Q:Lightning protection with a TV antenna?
while your hair is wet you can do two things: braid it and sleep on it/let it dry. This won't really be curly but it is a different, pretty look twist it around your finger and twirl it into a bun on top of your head. Secure with a bobby pin and sleep on it/let it dry the curls won't be perfect but they will look ok.
Q:Is there any food grade epoxy resin?
No Although the epoxy resin itself is non-toxic, but due to the addition of solvents and other toxins in the preparation process, resulting in a lot of epoxy resin "toxic.".
Q:Epoxy flooring construction program has several steps
Blow more than two times epoxy quartz mortar. Quartz sand and putty parts are used for leveling the base surface of the floor and increasing the coating thickness in order to improve the abrasion resistance of the floor. Because quartz sand filling rough, so floor paint mortar layer is relatively rough, there are more pores, the first mortar can effectively leveling floor paint construction surface.
Q:How about the resin strap?
The strap is more comfortable to wear. But if wet, with some stained plastic or other objects put together, it is contaminated with color, and once it's dyed, it's hard to get out. Therefore, I do not advocate buying white resin strap. I used to have a watch with a white strap and it was dirty a week later. In addition, if the resin strap is not cleaned for a long time, sweat and dust are gathered on it, which will speed up the aging of the strap and cause bacteria to produce odor. Therefore, it is best to buy the anti bacteria, odor watchband (e.g. Casio, G-shock), of course, the price is also more expensive. Also, the resin strap will be aging, and don't let it be exposed to intense sunlight for a long time.
Q:How can the resin lenses be repaired?
The lenses are worn out and can not be repaired. Usually can pay attention to the maintenance of lenses, can extend the service life.The resin lens is an optical lens with resin as material.
Q:What is the resin PP material?
It is polypropylene resin, and PP is a semi crystalline material. It is harder than PE and has a higher melting point.
Q:What is bakelite?
It has the advantages of water resistance, oil resistance, wear resistance, chemical resistance, mildew resistance, aging resistance and good electrical insulation performance. Itself is easy to modify, but also to other adhesives modified. In addition, it is brittle, low peel strength, shock resistance, vibration, the need for high temperature and high pressure curing for a long time, the shrinkage rate is greater, the color of the adhesive layer is deeper.
Q:Classification of resin flakes (by refractive index)
1.56, 1.61.1.67 is a relatively common refraction rate of 1.499 is generally not white resin coated, is not common. 1.74 and 1.76 are ultra wave high-end lenses, even if the general brand is also a few thousand dollars a pair
Q:Why should the new resin be disposed of? How do we deal with it?
The new ion exchange resin, because often contain a small amount of low polymer and end in polymerization material, in addition to the organic matter, usually contains iron, aluminum, copper and other inorganic substances; therefore, when in contact with water, acid, alkali resin or other solution, the soluble impurities will be transferred to the solution and influence water quality. Therefore, the new resin should be treated before use.
Q:Fusible polytetrafluoroethylene and poly perfluoroalkoxy resin what is the difference?
PFA is polytetrafluoroethylene modified, temperature can reach 260 degrees, perfluoroalkyl resin, PFA resin is relatively new melt processable fluorine plastic. The melting point of PFA is about 580 degrees Fahrenheit, density of 2.13 - 2.16g/cc (g / cm3). PFA is similar to PTFE and FEP, but at 302 degrees above, mechanical performance is better than FEP, and can be as high as 500 degrees Fahrenheit temperature of use, its chemical resistance and PTEF. PFA's products include granular products for molding and extrusion, powder products for rotational molding and coatings, and semi-finished products including membranes, panels, rods and tubing.
