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?
For wood adhesion, excellent adhesion strength, and water resistance, durability and heat resistance characteristics. And the advantages of room temperature curing. Therefore, in water resistance requirements of wood processing and wood bonding, such as water resistant plywood, water resistant wood chip board, wooden keel and senior ski, and so on, has a very important position.
Q:What effect does the resin play on the paint?
There are many kinds of resin, and the resins used in coil coating are acrylic resin, epoxy resin, polyester resin and polyurethane resin. Different tree fat, its physical and chemical properties, as well as weather resistance, corrosion resistance and so on are not the same.
Q:Epoxy resin is not that we often say that ab?
Ordinary epoxy crystalline rubber is made of high-purity epoxy resin, curing agent and.Gracie crystal glue experts will be modified, the cured product with water resistance, chemical corrosion resistance, yellowing resistance, crystal clear of the characteristics.Currently on the market can be divided into: crystal plane, plane soft hard rubber, soft plastic, hard rubber, arc arc filling glue, glue, polishing process of false water.The use of crystal glue can play a protective role on the surface of handicrafts and ornaments, besides, it can also increase the glossiness and brightness of the product surface.The crystal glue is suitable for post production studio album, photo album cover, badges, panels, labels, signs, automotive panels, metal, glass, badges, belt buckle, solar panel, LED packaging products, wood, stone.
Q:How can I get a good fiberglass mesh with resin?
The resin has better flowability and longer impregnation time;If possible, the mesh cloth should not be too dense and can be treated with a coupling agent before impregnating, and then the bonding will be better
Q:Can the resin glasses break?
According to knock sound, knock the lens is crisp sound or blunt voice, the former is glass, the latter is resin. Resin lenses are not easily broken under normal use unless they are inferior resin lenses.
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 is the principle of exchange of sodium ion resin?
The sodium ion exchange principle is the atomic softening treatment by sodium cation exchange resin, so that the water hardness components Ca2+, Mg2+ and Na+ in resin exchange, and adsorption of Ca2+, Mg2+, the water softening. For example, "RNa" stands for sodium type resin and its exchange process is as follows:2RNa+ Ca2+==R2Ca+2Na+2RNa+ Mg2+==R2 Mg+2Na+That is, the water passes through the sodium ion exchanger, and the Ca2+ and Mg2+ in the water are replaced by Na+. After a primary Na+ exchange, the residual hardness of water is generally less than 1.5 * 10-2mmol/L, which can be used for low pressure boilers.
Q:In unsaturated resins, what do solids refer to?
Gel timeThe gelation time is generally gel time was measured at 25 DEG C or 80 DEG.25 DEG C refers to the resin from adding initiator and accelerator to become soft and gelatinous mobility lost time. Sometimes the gel time can also be interpreted as the resin in the actual construction process of the operational impact time. Very large temperature and humidity environment, the gel time of initiator and accelerator dosage on the resin.
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.;
Q:How much is the resin tile one square meter?
The price is really bad, unified said, you can ask, PVC tile is based on polyvinyl chloride resin (referred to as PVC) as the main raw material
