Q:Principle of resin purifying water quality
The resin in the water softener also has the function of regeneration, which makes the use cycle grow
Q:The resorcinol resin needs to be mixed with POM powder to produce the last adhesive used to glue the sheet. Usually, how much harmful substance will be produced in industrial production?
Resorcinol formaldehyde resin slurry by 1 mol 0.6~0.66 Moore resorcinol and formaldehyde, reaction in the presence of acid or alkaline catalyst, without catalyst, required reaction at 100 to 150 DEG C, cooling after dilution with ethanol, stabilizing the. Before use, add formaldehyde (paraformaldehyde), so that the ratio of phenol to aldehyde is 1:1 ~ 2, which can be cured at room temperature. The adhesive is water-soluble and is most stable at pH 3~4 and the gelation rate is fastest when pH is 6~10. As filler, there are sawdust, walnut shell powder, etc., as modifier or additive of corn protein, cement, polyvinyl alcohol and so on.
Q:Corrosion resistance of epoxy resinHow many pH value acids and bases are there?Is it antiseptic to use epoxy resin to resist water?
10% liquid, 100 degrees, can guarantee a month without damage.
Q:Why multistage dilution is used in the later production process of resin?
The chemical composition of epoxy resin is the main component: phenolic resin; phenolic resin is composed of phenol formaldehyde resin, under the condition of the catalyst by neutralization and washing and made of the phenol and formaldehyde resin as the most important. It is also the earliest synthetic polymer which is still very important in the world.
Q:The difference between an epoxy solvent and a non solvent type is that the resin is not the floor
If from the environmental point of view, of course, non solvent based good, non solvent based utilization rate, odorless, solvent type is generally solid epoxy dissolved good. Solvent type used in coating more, solvent type used in adhesives and other solvent free system is more.
Q:Lighting industry to do the lamp rack, there are many resin materials used, I ask what kind of material in the end, what are the advantages?
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.
Q:What is called Resol type phenolic resin and Resol type phenolic resin prepolymer?
May be liquids, semi solids, or solids. Soluble in ethanol, acetone and alkali solution, slightly soluble in water. After a long time of heating, gradually lose its soluble fusible property, and become insoluble, non melting solid.
Q:How long does it take to complete the whole resin filling
We should pay attention to 2 hours should not eat filling resin dental teeth, because the tree refers to a certain time to harden teeth, and teeth after eating to avoid chewing side teeth. When the resin has been hardened and cured, the normal diet function can be resumed. Dental fillings after the masticatory function of teeth seriously, how long can use after dental resin dental fillings so that should be paid attention to oral protection, attention must not bite should be excellent resin fillings filled teeth after food.
Q:What is resin? Where did it come from?
Resin is a plant derived from a variety of plants and is the secretion of hydrocarbons (hydrocarbons) from conifers. Because of special chemical structure, and can be used as adhesive and latex paint as materials, have attracted much attention for its value. It's a mixture of many polymers, so they have different melting points. Resin can be divided into two kinds of natural resin and synthetic resin. Only this kind of natural resin itself, but with the development of chemical industry, there are many from synthetic polymers, among the chemical and physical properties of some polymers and natural resin is very similar, therefore, the polymer is called synthetic resin.
Q:The same toys, vinyl resin and the two materials which is better?
Resins are made of natural resins and synthetic resins. Natural resin is an amorphous organic matter from the secretions of plants and animals in nature, such as rosin, shellac, amber, etc.. A synthetic resin is a resin product obtained by the chemical synthesis of a simple organic substance or by the chemical reaction of some natural products.
