Q:What's the difference between a macroporous resin and a polyamide resin?
Macroporous resin1. principle: macroporous adsorption resin is based on styrene and propionate as monomer, adding ethylene, benzene as cross-linking agent, toluene and xylene as pore forming agent, they are cross-linked and polymerized to form a porous skeleton structureDifferent from the ion exchange resin used in the past, macroporous adsorption resin is a separation material which combines the principle of adsorption and screeningAdsorption is the result of van Edward force or hydrogen bondingThe screening is due to its porous structureTherefore, the organic compounds can be separated according to the adsorption force and the molecular weight, depending on the adsorption mechanism and screening principle of the resin
Q:Using unsaturated resin to make glass fiber reinforced plastic products, without adding accelerant, only curing agent, can I? What is the function of accelerant?
The curing reaction of unsaturated polyester resin is free radical polymerization, and its curing agent is actually an initiator, usually organic peroxide.
Q:How about resin glasses?
1, light quality, comfortable wearing.2, material elasticity is good, not easy to cause destructive deformation (for example, put on a chair, a butt sit up? Most resins, frames, glasses, and the possibility of continued use.3, the lens in the high impact of fragmentation, resulting in small hardness, edge than glass crystal debris sharpness is small, reducing the damage to the eye. High standard resin goggles are the standard safety protection equipment for foreign labor protection and shooting training. (some shooting goggles can withstand 6 mm gun shot front)
Q:Resin buttons, wool, plates and bars what is the difference between the price, which is more expensive, what are their respective characteristics?
Because the plate is washed into a cylindrical, like drawing on a white paper round, round between the circle there is a gap, this gap is the charge. This bar no trouble, although he also has what we call the head, but the cost is not expected to be too much
Q:Epoxy resin coating
Interpenetrating network wear-resistant coating. After curing, a interpenetrating network polymer anticorrosion coating between epoxy resin chain and rubber chain is formed, thereby effectively preventing the change of coating and improving the weatherability of coating.
Q:What kind of sandpaper should be used for sanding the resin model?
Don't use a piece of money ah what domestic Eagle like this one, and, with rich Tamiya, followed by Germany warriors are good.GK pieces are relatively hard, usually 600 or 800 of the whole body grinding, remove the nozzle and parting line, and then fill the surface bubbles. Then use 1000 sanding and then 1500 sanding to remove surface scratches.
Q:What is the difference between resin, plastic, fiber and rubber?
Synthetic resin is the main ingredient of plastics, plastics content in general 40% ~ 100%. due to the content, and properties of the resin is often decided by the plastic properties, so people often think of resin as a synonym for plastic.
Q:In unsaturated resins, what do solids refer to?
acid valueIs that the extent of reaction resin acid value index. The acid value is defined as the number of milligrams of KOH required with 1g resin, the acid value in mgKOH/g. Generally speaking, the smaller the reaction of high acid resin, resin acid and its formula but a great relationship, eventually stuffed formula values of different resins different.
Q:Epoxy resin conductive, do not let it conductive, can you?
Epoxy resin paint is needed to prevent static electricity. It is necessary to buy special anti-static floor paint of epoxy resin. This kind of floor paint is divided into two kinds:1, general anti-static floor, usually add conductive powder2, self leveling anti-static flooring, generally are adding conductive fiber.The main application scene of anti-static floor:Computer room, precision instrument production workshop, etc.
Q:How much is the epoxy floor?
Focus on high-end environmentally friendly epoxy flooring customization;Epoxy flooring series is various, including flat coating epoxy floor, epoxy mortar floor, epoxy self leveling flooring, epoxy flooring sand, non slip epoxy flooring, epoxy anti-static floor etc.;
