Q:Carbon fiber bicycle, advantages and disadvantages

Advantages of carbon fiber bicycles:1, light weight. The carbon fiber is less than 1/4 of steel, and the frame weight is made of carbon fiber. It is 1/4 of the common alloy frame.2, impact absorption is good. Carbon fibers are used in making special springs and are used in various fields because they absorb shock and have excellent performance. A bicycle without a shock absorber can also be made3, modelling is easy. A variety of shapes of frames can be made from carbon fibers. Because a fiber sheet is spread on the mold, and then flows into the resin and burns solid, it can be made into a carbon fiber frame with various shapes, which is very convenient.

Q:What's the difference between high density fiberboard, oak and fir?

Are oak and fir trees pure solid wood? Or MDF, wood, oak, fir? Or MDF, PVC, oak and cedar? The price difference between the three is great.MDF is man-made board. Is a number of wood debris, in accordance with a certain proportion of glue, through some process of repression, and there is a green index, divided into E0, E1, E2 three levels. Strength, hardness, you can rest assured, if you ventilation indoor, moldy, do not worry.Oak, pine, fir wood is relatively scarce, in general, if the oak is solid, then it is oak finger board or fir finger board, the cabinet is more environmentally friendly, but also through some process can be used to make the cabinet, so rest assured you will not moldy.

Q:How about the fabric panties of bamboo fiber?

Bamboo fiber is a kind of cellulose fiber extracted from natural bamboo. It is the fifth natural fiber after cotton, hemp, wool and silk.Bamboo fiber has the characteristics of good air permeability, instant water absorption, strong abrasion resistance and good dyeing property. Meanwhile, it has the functions of natural antibacterial, bacteriostasis, mite removal, deodorization and anti ultraviolet. Bamboo fiber is a kind of natural environmental friendly green fiber in real sense. The bamboo fiber textile completely replicates the natural characteristics of the bamboo fiber.Buy a high content of bamboo fiber, so that it is comfortable to wear, washing to use medium washing liquid.

Q:What is the accuracy of the hollow fiber and the ceramic filter core of the filter?

The filtration accuracy of the hollow fiber membrane is 0.01 microns, and the filtered water can intercept most of the bacteria and viruses, and the purification effect is only second to the reverse osmosis membrane. Ceramic filter accuracy to see the quality of ceramics.

Q:What fabric is sticky fiber?

Usage: because of good moisture absorption, comfortable wearing and good spinnability, it is often blended with cotton, wool or synthetic fiber, and used in all kinds of clothing and decorative textiles. High strength viscose fiber can also be used in tire cord, conveyor belt and other industrial products.

Q:Can polyester fiber have static electricity?

Electrostatic.The disadvantage of polyester fiber is that it is easy to absorb dust and produce static electricity. Wearing polyester fiber fabric clothes are easily contaminated by dust, not only caused not beautiful, most people dislike is static, not only feel tingling, and if it is also because the static relationship between pants pants close to the skin, completely lost clothing, not very beautiful.

Q:What's the difference between polyester fiber and cotton?

Polyester fiber is an important variety of synthetic fiber, and it is the commodity name of polyester fiber in our country. It is a pure terephthalic acid (PTA) or terephthalic acid methyl ester two (DMT) and ethylene glycol (EG) as a fiber polymer, polyethylene terephthalate as raw materials by esterification or transesterification and polycondensation prepared (PET), the spinning and postprocessing fibers.

Q:Why does pure cotton fabric fall off?

Although a lot of floating hair has been reduced, but the plant fiber has also lost its original vitality, so the treated fabric will easily cause residual chemical components, long-term exposure will have a greater harm to human health.

Q:What are the elastic fibers and collagen fibers?

Elastic fibers (elastic fiber) elastic fiber yellow in loose connective tissue slightly, strong refraction, elastic. Generally more delicate than collagen fibers, fibers have branches, arranged scattered. Its chemical composition is mainly elastin (elastin), which has greater tolerance to traction. Elastic fibers of the skin and tendons are produced by fibroblasts, which are produced by smooth muscle cells in large vessels. Elastic fiber Description: dyed blue, purple, a single distribution, has branches, and woven into a net. SEM observation showed that elastic fiber contained two components: Micro fibril and homogeneous substance. Fibrils are arranged in the form of structural glycoproteins that surround the homogeneous substance, elastin.

Q:Why carbon fiber is an inorganic macromolecule compound?

Between high and low molecular weight probably with molecular weight 2000 division, carbon fiber structure has no clear judgment, but somewhat similar to graphite and graphite, for a large number of a plurality of graphene layers connected each other with a pi bond, as a whole, big molecular weight, it can be divided into sub score
