Q:EVA material is plastic or rubber?
EVA resin is a copolymer of ethylene vinyl acetate, ethylene vinyl acetate (VA) content in 5% ~ 40%. compared with polyethylene, EVA in molecular chain was introduced in vinyl acetate monomer, thereby reducing the high crystallinity, improved flexibility, impact resistance, filler compatibility and heat sealing performance, is widely used in the foaming shoes material, functional films, packaging film, hot melt adhesive, wire and cable and toys and other fields.
Q:Are resins the same as polyurethane?
As far as polyurethanes are concerned, it is obtained by the reaction of polyols and isocyanates.
Q:What is the difference between PVC material and resin?
Resin usually refers to softening or melting range after heating. When softening, it tends to flow under external force. At normal temperature, it is solid, semi solid, and sometimes liquid organic polymer. Broadly speaking, any polymer compound that can be used as plastic material for processing raw materials is called resin. Resin is the main raw materials for the manufacture of plastics, paint is also used the system (the main film-forming material, coating such as alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in the Yangtze River Delta and Pearl River Delta are also relatively strong in the paint industry, such as Changxin chemical, Nuplex resin, three resin, Ying DSM syntech resins), adhesives, insulating material, synthetic resin in industrial production, is widely used in separation and purification of impurities in liquid, with macroporous adsorption resin, ion exchange resin, and some special resin.
Q:What is resin sand casting, what is called coated sand casting?What are the advantages and what are they used for?
When heated in the resin coated sand coated sand surface melting, the decomposition of methylene urotropin under the action of the body structure of molten resin is composed of linear structure quickly into the melt, so that the coated sand curing. The coated sand is generally dry granular, in recent years China has been a manufacturer to develop wet and sticky the shape of coated sand.
Q:Who knows where the pine resin should be sold? What is the general market price? Consult your experts.
The resin is colorless and transparent when it flows out of the resin duct of the pine trunk, and its terpene content is up to 36%. After contact with air, terpenes evaporate rapidly, while the resin acid crystallizes in a crystalline form, and the rosin itself becomes dense and half fluid like a honey. Resin from the forest zone to the factory often contains a variety of mechanical mixtures, including pine needles, bark, wood chips, insects, and dust.
Q:How much can the epoxy resin floor be able to bear?
Several common epoxy floor thickness, its load-bearing capacity:When building epoxy flooring, the surface requirement is very high.The concrete foundation ground, flatness and surface strength can be used 1 thin epoxy floor coating, if the surface smoothness and the poor strength of the ground, need to repair the ground leveling, strength and smoothness, can use 1 ~ 3 mm epoxy mortar floor, according to senior engineering can use 2 ~ 3 mm epoxy self leveling floor; the wear resistance, load stress properties such as surface decorative effect than ordinary epoxy and epoxy mortar floor is better, it is very important to choose a suitable color epoxy floor, can be their own choice, general garage parking Ping commonly used color: grey, blue, green, paint color yellow, white.
Q:Unsaturated resin flame retardant classification and description, who can provide?
Flame retardant, organic phosphorus polymer added metaphosphate type flame retardant flame retardant the combustion generated can form a stable, covered on the surface of the composite materials from oxygen and combustible, play the effect of flame retardant, the flame retardant effect is better than that of bromide, to achieve the same effect of flame retardant, bromide dosage phosphide 4 ~ 7 times. This type of flame retardants are mainly phosphorus (phosphine) ester and Halogenated Phosphate and phosphorus halide, widely used in epoxy resin, phenolic resin, polyester, polyurethane, polycarbonate, polyvinyl chloride, polyethylene, polypropylene, ABS etc..
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:What is called regeneration of ion exchange resins?
The regeneration characteristics of resin are closely related to its type and structure. The regeneration of strong acid and strong alkaline resin is difficult. The regeneration dose is much higher than the theoretical value, while the weak acid or weak base resin is easy to regenerate, and the regeneration dose needs only a little more than the theoretical value. In addition, resins with large pass and low cross linking degree are easy to regenerate, while those with gel type and high crosslinking degree have longer regeneration reaction time.The type of recycling agent should be selected according to the ion type of resin, and appropriate choice of lower prices of acids, bases or salts. For example: sodium type strong acid cation resin can be used to regenerate the 10%NaCl solution, 2 times of dosage for its exchange capacity (NaCl 117g/ l resin); hydrogen type strong acidic resin with strong acid regeneration, reaction with sulfuric acid to produce calcium sulfate precipitate with calcium sulfate to prevent by resin adsorption. For this reason, it is better to pass through the dilute sulfuric acid regeneration of 1 ~ 2%.
Q:Use of rosin resins?
Woodrosin is from residual rosin pile or root by solvent extraction, distillation and separation of volatile oil and preparation, quality as well. The quality of rosin rosin by color, acid value, softening point and so on. In more than 90% grade rosin for various isomers of abietic acid, the other is the acid some esters and unsaponifiable matter. Abietic acid is a weak acid, esterification and saponification reaction can be carried out; is very sensitive to the role of oxygen, oxidation of the rosin become darker in color, also can be polymerized to form a dimer of two; in 250 ~ 260C. The thermal decomposition of rosin is mainly used for soap, paper and other industries, made all kinds of processing products such as soap, such as pine rosin ester rosin used in coating industry. In China production, mainly in the southwest and Southern China.
