Q:What's the resin like? Did you buy a money box today?
Piggy is small crafts, fell to see resistance intolerant thickness, may not like other materials, it all go bad, but fell, how much will be missing a little bit! More resistant than other materials!
Q:Principle of resin purifying water quality
Regeneration process:When all exchanged ions on the resin are converted to calcium and magnesium, the resin becomes saturated and fails to regenerate. The process is as follows: firstly, the backwash flush surface closure of the impurity in the recycled salt salt absorption valve, high concentration brine by resin, calcium and magnesium ions on the resin squeezed out, will be fully restored to the ion exchange resin will restore the sodium ion and sodium ion resin.
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 resin called soft resin, curing is very soft, twisting, bending are not deformed
Polyurethane material is the abbreviation of polyurethane. The English name is polyurethane. It is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the "Fifth Plastic", because of its outstanding performance has been widely used in many areas of the national economy.
Q:What is the difference between acrylic and resin?
Plastic: plastic (Plastics): plastic behavior of the material, the so-called plastic refers to the external force of the deformation occurs, the external force can be maintained after the abolition of the state of force. The elastic modulus of plastic is between rubber and fiber, and it can deform in a certain way. Soft plastics close to rubber, hard plastics, close to fiber.
Q:What is the difference between polyester and resin?
Polyester mainly refers to a class of substances that contain ester groups
Q:What is resin? What's it for?
Some of the trees, when injured, it will secrete a thick, a little sticky substance, sometimes it is solid, this is the resin (Resins). We often come into contact with benzoin (Benzoin) is a kind of resin.
Q:What is the difference between thermosetting and thermoplastic?
The first heating can soften the flow, heating to a certain temperature, a chemical reaction, a chain solidified and hardened, this change is irreversible, and then again heating, it can no longer soft flow. It is by virtue of this characteristic of molding, the use of the first heating of the plastic flow, under pressure filled cavity, and then solidified into a shape and size of the product. This material is called thermosetting plastic.Thermosetting resins are linear or branched before curing, forming a chemical bond between the molecular chains after curing, becoming a network of three degrees, not only without melting, but also insoluble in solvents. Bakelite, formaldehyde, melamine, formaldehyde, epoxy, unsaturated polyester, silicone and other plastics are thermosetting plastics.
Q:Definition and difference of wet real density and wet apparent density of resin?
Wet density: the density of resin particles when a resin expands sufficiently in water. This value is generally between 1.04 and 1.3.
Q:What is the difference between resin, plastic, fiber and rubber?
Plastic refers to the organic synthetic resin as the main ingredient, added or not with other materials (additive) and artificial material. It is usually in the heat and pressure under the condition of plastic devices made with a certain shape. Plastic is a synthetic high molecular organic compounds with plasticity.
