Q:What are gypsum powder reinforced resins?
(lightweight high-strength foam gypsum handicraft, weight ratio), gypsum powder 89-99%, rubber polymer latex 2.8, starch 0.5-5, surfactant 0.1~0.2. Dosage of water and gypsum; latex foaming agent 0.1~0.2; preparation and use; dissolve additives in water; then mix with gypsum powder to make.
Q:What is resin chemistry?
Resin chemical is related to the chemical resin baaNot a plastic resin, the resin is heated usually a softening or melting range, softening tendency to flow under the external force, room temperature is solid, semi-solid, sometimes can be a liquid organic polymer. Broadly speaking, any polymer can be used as raw materials for plastic products are called resins.Resin and synthetic resinnatural resin of the points. The natural resin is amorphous organic matter from the secretions of plants and animals in nature, such as rosin, shellac, amber. Synthetic resin is chemically synthesized from simple organic compounds or some natural products obtained by chemical reaction of the resin product.Purpose: food grade industrial grade; grade; analysis; nuclear grade resin; double bed; high velocity with mixed bed resin; and the filter cover resin with moving bed.
Q:What can be used to make phenolic resins not so thick?
But there are certain toxic and volatile phenolic resin, in addition to doing very directly to bakelite plate dilution, wear a mask to do protective measures, health first. Hope to be of some help to you.
Q:What are the differences in the properties of petroleum resins and rosin resins in adhesive bonding?
We predict that rosin resin will replace petroleum resin more in the next few years. By 2015, the proportion of rosin resin will reach more than 30%, and the demand will exceed 280 thousand tons.Rosin resin is used as a tackifier in adhesive products to increase initial adhesion, improve wettability and plasticity, and promote mixing of fillers and polymers. As mentioned above, compared with petroleum resin, both have their own advantages. Generally speaking, the initial viscosity of rosin resin is good, and the aging resistance of petroleum resin is good. Moreover, in the further development of technology and technology, the performance of rosin resin in the aging resistance is also gradually improved, and compared with the oil resin, the gap is not big.
Q:What is the resin PP material?
Copolymer type PP material has lower thermal distortion temperature (100C), low transparency, low gloss and low rigidity, but has stronger impact strength. The strength of PP increases with the increase of ethylene content. PP VEKA softening temperature is 150C. Because of its high crystallinity, the surface stiffness and scratch resistance of this material are very good.
Q:The difference between resin, plexiglass and glass fiber reinforced plastics
Glass fiber reinforced plastic is another name for glass fiber reinforced plastics, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastic. Depending on the fiber used, glass fiber reinforced plastics (GFRP), carbon fiber reinforced plastic (CFRP), boron fiber reinforced composite plastics and so on are classified. It is a kind of composite material made of glass fiber and its products (glass cloth, band, felt, yarn, etc.) as reinforcing material and synthetic resin as base material. Fiber reinforced composites are composed of reinforced fibers and matrix. Fiber (or whisker) diameter is very small, generally below 10 mu m, less defects and smaller, fracture strain of about 30/1000, is brittle material, easy to damage, fracture and corrosion. The matrix is much lower in strength and modulus than fiber, but it can withstand large strains, often with viscoelasticity and elasticity, and is a ductile material.
Q:Ask for some introduction of thermosetting materials, it is best to have advantages and disadvantages are issued
Characteristics of epoxy resins (usually bisphenol A epoxy resins)1., the application of epoxy resin is very low value, it needs to be used in conjunction with the curing agent, it has practical value.2. high bonding strength: in synthetic adhesive, the adhesive strength of epoxy resin is in the forefront.3. curing shrinkage is small, in the adhesive, the shrinkage of epoxy resin is the smallest, which is also the reason for the high adhesion of epoxy resin adhesive
Q:Make leather shoes, polyurethane resin glue
These things are secret, generally commercial secrets ah, the answer here do not believe in chaos ah!
Q:What is the chemical name of the resin?
Rosin, benzoin is a natural resin, phenolic resin, polyvinyl chloride resin, synthetic resin.
Q:What kind of sandpaper should be used for sanding the resin model?
Water, fill the soil, do as much as 1000 of the soil, five stars with 1200 or 1000 of the soil can be.Use 1500 sanding paper to inspect the surface. The surface is hollow and filled with toothpaste.By spraying, mending and sanding several times, the surface is smooth and without bubbles.
