Novokart launches folding bike, Ireland embraces cycling.

As Ireland emerged from the blockade, one thing became clear: the country's love of cycling. Bike shops across the country have sold out of bikes as a large number of people see cycling as a way to spend more time outdoors and to be closer to home.

Aware of the demand for bike-related items, Aldi will sell folding bikes (349.99 euros) in 142 Aldi stores across the country from Thursday, August 6.

A folding bike is any bike designed to fold into a more compact form, making it easier to carry, store, or fit in an area that would normally not be able to carry a regular bike. They are intermodal bikes because you can transport them from the back of a car to a train or bus and then cycle the rest of the way!

FRP Raw Materials

Posted by marking2020 marking2020·Jul 06

I. Overview

It has been more than 60 years since the birth of FRP. It has developed from simple hand lay-up process to today’s computer-controlled operation. Our products have different performances and varieties, which are all over our life.

II. Raw materials of FRP

I) Glass fiber

Glass fiber is made of glass, which is pulled down in high temperature melting state. Its diameter is generally 0.5-30 μ m, and its surface is treated with coupling agent, which improves the adhesion with resin. It is a reinforced material in FRP, mainly providing strength.
Classification, performance and products

According to the chemical composition, it can be divided into non alkali, medium alkali and high alkali glass fibers, which are expressed by E, C and a respectively. E glass has high strength, alkali resistance, water resistance, heat resistance, good electrical insulation and poor acid resistance. C glass a glass has better acid resistance, but other properties are not as good as E glass. The specific gravity of glass fiber is about 2.5. The surface felt, chopped felt, winding yarn and alkali free cloth used by our company belong to e glass.

Common products–

1) winding yarn

According to the production process, it can be divided into direct yarn and indirect yarn (composite yarn)

Model: 1200tex, 2400tex, 4800tex. Tex: 1000 m single strand yarn weight.

2) chopped felt: it is made of 50-70mm short fiber. Common specification: 300g / m2450g / m2

3) knitted felt: common specifications: 380g / m2, 450g / m2

4) glass fiber cloth: the unique production process of glass fiber surface felt determines that it has the characteristics of smooth surface, uniform fiber dispersion, smooth handle, good air permeability and fast resin penetration. The surface felt is used for FRP products. Its good air permeability can make the resin penetrate quickly and eliminate bubbles and white stains completely. Its good formability is suitable for any kind of complex products and molded products. It can cover the cloth grain, improve the surface finish and leakproofness. At the same time, it can enhance the interlaminar shear strength and surface toughness, and improve the corrosion resistance and weather resistance of the products It is necessary for making high partial strand FRP mould and products. The products are suitable for FRP hand lay up, winding, pultrusion, continuous plate, vacuum absorption molding and other processes.

Neutral alkali cloth — 0.2:180g / m2; 0.4:360g / m2

Alkali free cloth — 0.4:400g / m2; 0.6:570g / m2, etc

5) surface felt: as above

Specification: 30g / m2, 50g / m2

II) Resin

Resin is the matrix material in FRP, its function is to transfer force load between fibers, it determines the heat resistance, corrosion resistance and aging resistance of FRP. There are two kinds of resins: thermoplastic and thermosetting. The commonly used FRP is produced by thermosetting resin. The so-called thermosetting resin refers to the formation of insoluble and insoluble materials after curing. If the temperature is too high, it will break down. Commonly used are unsaturated polyester resin, epoxy resin, phenolic resin. This paper mainly introduces unsaturated polyester resin.

Classification of unsaturated polyester resin

The classification of unsaturated polyester resin is generally divided into general type, heat-resistant type, chemical resistant type, light stable type, self extinguishing type and sewing type. According to the chemical composition, it can be divided into ortho benzene type, m-benzene type, bisphenol a type and vinyl type.

Among the commonly used brands, 192a and p65-90119119886 belong to o-benzene resin, which is mostly used for structural fabrication; 2028972 belongs to m-benzene type, which can be used as lining or structural layer: 9503 is p-benzene type; 3301197382941 belongs to bisphenol a type, which is used for lining fabrication, which is used for places with high requirements of chemical corrosion resistance; 470430590.3201, MFE-2 and w2-1 belong to vinyl type or improved type C-type resin, used for chemical corrosion resistance, higher temperature requirements. 2028382976a belongs to food grade resin, which is used to make FRP pipes or containers for conveying or storing tap water or food.

III) Auxiliary materials

Colorant (pigment), wear-resistant agent (quartz powder, diamond powder, etc.), flame retardant (halide), quartz sand with increased rigidity, antistatic agent (graphite), etc.

I have to sleep with a quilt, Buffy Breeze keeps me cool

I consider myself a fairly good sleeper, as long as my bedroom is quiet, dark, cool and has a bed with a fluffy quilt.It's midnight, 90 degrees, 90% humidity doesn't matter, I want to snuggle under the clouds I made, I don't want to feel a drop of sweat.That's why, after hearing the 145th podcast AD for Buffy Breeze Comforter ($219), I was the game to give it a try.

My favorite podcasts brag that this blanket feels like any winter heavyweight, but because it's made from 100% eucalyptus stuffing, it won't capture the heat like polyester or down.It is also made from recycled thread and feels cool, with a eucalyptus fibre shell that regulates temperature.So much for that.This blanket is for the down carpet stalwarts who can't give up the comfortable feeling...Even in July.

When my Breeze Comforter box arrived, I was surprised. It felt heavy.Like, I wonder if I accidentally ordered a weighted blanket.But when I opened up the minimalist packaging -- hats off to Buffy, even in that category -- I didn't see a weighted blanket, just an ultra-thin duvet.In fact, it's actually a fairly thin blanket, but I can confirm that its wavy quilt detail looks as cool as it does on Instagram.(It also helps to keep the down in place, fYI.)The thin outline of the blanket has also proved to be a benefit of tucking it into the down quilt cover;Once I tie the four rings and shake the lid over them, the whole process is easier than my oversized winter duvet.Sure, my bed doesn't look as perfect as one covered with four-inch down feathers, but that's to be expected from a thinner blanket.

So, on my first night, by the way, how did the daffodil blanket fare without air-conditioning and with only one fan in the room?Still, I had to dance in and out for comfort, but once I did, I dozed off, slept through the night and woke up feeling cool (and not sweating).Yes, there is no overheating.A few nights later, when it was time to turn on the air conditioner for the first time, the comforter settled in.

Still, feeling is more than just sleeping under the sheets. That's what I learned before puffing on the bed.Daffodil is still a blanket, and the eucalyptus stuffing does make you feel warm, but it doesn't burn.Especially if, like me, you sleep on the top of a feather mattress, which is known to trap a little extra heat.

But here's something: I can actually see myself using this blanket all year round, not just during the summer months.When layered with cozy cashmere or wool, it's warm enough deep in winter, and it's sure to be my favorite place throughout the fall.While I don't like Buffy's suggestion to take it to the dry cleaner (because it's sure to cost a fortune), the fact that the blanket is made in a sustainable way does, literally, help me sleep better at night.

So if you're looking for a life-changing blanket that feels like you're sleeping in an air conditioner on the hottest day of the year, this isn't it.However, if you are looking for a lightweight duvet that works every season, is environmentally friendly and comfortable AF and won't make you sweat in your sleep, Buffy is it.Have a nice dream

Brompton Bicycle’s UK online sales soar fivefold during lockdown
Brompton ​Bicycle has said it sold five times as many bikes online since launching its Direct to Home initiative at the start of April, a week after the UK entered lockdown.
Many of the bike shops the West London-based company would usually trade through are either closed completely or restricting their activities to servicing and repairs.
The shift online has therefore helped Brompton satisfy demand for its folding bikes, much of it from people looking to switch to cycling for their commutes and avoid public transport.
A spokesperson for the company told Telegraph.co.uk: (link is external) “Online sales from both our accredited retailers and via Brompton have grown rapidly (five times higher than the previous month) since the launch of our Direct To Home service at the start of April.”
They added that organic web traffic for the UK had also risen by 62 per cent during the past five weeks as people browse its bikes online.
To cater for the surge in online interest, the company has now introduced a video call service, named Brompton Live In-Store Expert, which puts customers in touch with staff from the Brompton Junction store opened last year at London’s Westfield White City.
The service, available from 10am-4pm Monday to Friday, enables customers to seek advice on Brompton’s range of bikes as well as accessories and clothing.

Stephen Loftus, Brompton’s chief commercial officer, said: “We have always been committed to deliver the highest level of customer service we can, and I am delighted we are able to now offer our customers an engaging way to access the expertise of our retail staff so that they can have confidence in finding their perfect Brompton and have it delivered to one our accredited retail stores or straight to their door.
“This new service is an example of how we are adapting and developing our business to meet the changing consumer needs due to the impact of COVID-19,” he added.
In March, the company’s Brompton Bike Hire arm started letting NHS key workers hire its bikes for free to enable them to get to work while avoiding public transport.
> Brompton Bike Hire in fundraising drive to make more bikes for NHS workers – here’s how you can help
Brompton also turned over part of the production facilities at its Greenford factory to support the Wheels For Heroes initiative enabling more bikes to be made available to NHS staff, and launched a crowdfunding campaign (link is external) so the public could also back it, with more than £300,000 raised to date.

Don't let your garden wilt in July's heat
After a cool spring, the last few weeks have been hot and dry in upstate New York. Although we can water to help with the drought, there’s not much we can do to protect our plants from the heat. And unfortunately, it can lead to lots of problems in our gardens.

Cool-season crops like peas and spinach just can’t take the heat. At Cornell AgriTech, my research includes an acre of peas with dozens of varieties. High temperatures are causing the peas to ripen quickly, from sweet and tender to hard and starchy in 24 hours. Spinach responds to heat by flowering and going to seed. Lettuce bolts too, but may take the heat a little better.
Although we think of tomatoes as heat-loving plants, they prefer more seasonable summer temperatures. Hot days over 90 degrees and warm nights over 80 degrees result in pollen sterility.

Heat impacts squash, zucchini and cucumbers both directly and indirectly. High temperatures lead to more male flowers at the expense of females. And it’s the female flowers we need to get fruit. Plus, hot days keeps bees from foraging and pollinating. So even if you have female flowers, you may notice them fall off as bees fail to do their job.

Tomatoes are not immune to the heat either. Although we think of them as heat-loving plants, they prefer more seasonable summer temperatures. Hot days over 90 degrees and warm nights over 80 degrees result in pollen sterility. Similar to squash, without viable pollen, you may notice flowers and pea-sized fruit fall off the plants.

Gardening in upstate NY: Cover crops can enrich soil, smother weeds

Gardening in upstate NY: If you need a snack, your plants may need one, too.

The condition is temporary, and fruiting will return to normal when it cools down. But that might explain the lack of fruit you might see about six weeks from now. That’s just about when the fruit that should be setting now would be ready for harvest. Peppers too have a similar problem with fruit and flowers falling off.

Snap bean flowers may also abort in the heat. That’s not a big problem for gardeners as production picks up again when the weather cools down. It is a huge problem for commercial growers, however, since they don’t have the luxury of picking a few beans every day. They get one chance to harvest their field with mechanical harvesters, so they need everything to ripen at one time.

The heat causes quality problems too. Cucumbers become more bitter due to a high level of cucurbitacin, a compound that occurs naturally in the fruit but usually at low levels. Stress of any kind tends to increase its level. The compound tends to accumulate in the stem end of the fruit and the skin. Just cut off the ends and peel to make a more palatable fruit.

Beets and carrots tend to lose color (and phytonutrients) as well as stored sugars in the heat. Better to wait until the weather cools down to harvest. Wait until autumn to harvest for the best root crops.

Is there anything you can do to minimize heat problems? First thing to do is keep up with watering. Dry soils make problems worse. To keep plants from wilting and drying up completely, water needs to move continuously from the soil into the roots and up through the leaves. The water is needed for photosynthesis, which of course powers the plant. But it also cools the leaf as it evaporates. Just like people, evaporation keeps plants cooler.

If it’s dry, the small pores on the leaves called stomata close.That stops water from evaporating from the leaves. This not only shuts down photosynthesis but causes leaves to heat up.

Midday sprinkling helps cool plants by increasing evaporation from leaf surfaces. Water lightly as your goal is to just wet the leaves and not provide a week’s worth of irrigation. Don’t overuse this method as it can increase disease problems due to the higher humidity. But it can help on the hottest days.

You can also try throwing some shade cloth over plants on hot days. Depending on the type of cloth, it can reduce the sunlight and the temperature a bit. This technique is probably best for crops like lettuce and spinach.

Now is a good time to add a layer of organic mulch to your soil. Wood chips, straw, shredded paper and grass clippings will reduce evaporation of water from the soil and keep it cooler.

Protecting your brassicas without chemicals
Brassica — better known as bok choy, broccoli, brussels sprouts, cabbage, cauliflower and kale — are all members of the Crucifer family of plants.

If you have grown these plants in your garden, you can hardly wait to munch on the first bunch of broccoli or crunchy leaves of kale.

As days pass, you might see big holes and chewed edges of plants or they may even be missing! Woodchucks and bunnies like these plants even more than you.

Both critters do major damage in very short order.

While scouting your garden, you may see green caterpillars (they are the same green color as the leaves) munching on your plants. The caterpillars are the larva of the Pieris rapae a.k.a. the cabbage butterfly — that is the innocent looking small mostly white butterfly you see fluttering about.

This is all very discouraging.

The caterpillars can be controlled chemically but this may not be something you are not willing to do. Also, spraying a Brassica plant can be a problem because the spray tends to roll right off.

Woodchuck and bunny control is a whole other article. As far as wildlife is concerned, if the attraction is removed, the critters will also move along.

After years of gardening I have found a non-chemical fix for all of this.

Covering your plants with cicada netting creates a physical barrier to block the woodchucks and bunnies from eating your plants and keeps the cabbage butterfly from laying its eggs.

You might have heard the saying “An ounce of prevention equals a pound of cure.” Cicada netting is plastic netting with a ¼-inch grid. You may have to order it from a supplier. Be sure that it is at least 12 feet wide.

Here is what I do.

First create a row of support hoops for the netting. You will need two 12 inch lengths of ½ inch rebar and a 10-foot piece of flexible ½-inch PVC pipe per hoop. To make a hoop, first place the rebar across from one another on either side of the row and push it into the ground as least half way. I make the distance between the rebar about 4 feet. I place the hoops about 10 feet apart.

On each end place a 10-foot piece of PVC pipe on the rebar to make a hoop. The 10-foot length makes for a high enough hoop to work under. Make enough hoops to cover the row. Then cover with the netting and secure the bottom. I used the landscape staples, but rocks, bricks, whatever you have around will do.

Since none of the Brassica plants need to be pollinated, the netting only needs to be removed for weeding and harvesting. (Weed cloth prior to planting can also be a good addition to this project.) The hoops also make a great support for shade cloth to protect these cool weather crops from the summer heat and then later they can support row covers to extend the season. I hope that you will give this a try.

Note: The cicada netting is great for bird protection of small fruits. It can be laid directly on top of blue berries or strawberries.
