Q:What is the reason that the performance of self - curing resin is lower than that of heat - curing resin?
Weather resistanceWeather resistance is one of the main characteristics of silicone resin and is widely used as base material for weather resistant coatings. The simplest way to test the weather resistance of coatings is to expose the test panels coated with silicone to the outside, and to observe the changes in gloss or color of the coating, as well as cracking. But because sunlight exposure, the specimens received in outdoor temperature changes, rain, snow, wind and frost attack, floating in the air and dust pollution of various chemical substances are not the same, so it is difficult to have strict standards. Making comparison and analysis difficult. In addition, the results of the cycle is long (in years), so the use of this method has been less, and now use accelerated aging test machine, to obtain weather resistance data. Under the condition of accelerated test, the coating gloss 60%, alkyd resin coating is 250h, containing 30% (mass fraction) silicone alkyd resin coating is 750H, containing 50% (mass fraction) silicone alkyd resin coating is 2000h, and the silicone coating after 3000h, the gloss retention is still higher than 80%. Among the many factors that cause coating aging, sunlight, especially ultraviolet radiation, is the major cause of low gloss and powder surface. It is known that the light spectrum in the wavelength spectrum of the solar spectrum on the earth's surface is very sensitive, which is the root cause of the poor weather resistance of organic resins. Known, methyl siloxane hardly absorb the ultraviolet light, containing PhSiO1.5 or Ph2SiO links are only following the absorption of 280nm silicone (including a small amount of ultraviolet light), the sun has little effect on the silicon resin, which is the main reason of silicon resin coating with excellent weatherability.
Q:Can water make a thinner of transparent resin that day?
Other used such as unsaturated polyester, epoxy resin or AB water such as 8014 corresponding active diluents were styrene, propylene carbonate and polyester polyol / styrene, can dilute the viscosity of resin and become a part of crosslinking in the framework. That day, the water because there is no cross-linking structure, can only be said to open dilute, plus 5-6% is already the limit. Unless the material is in short supply, it is not recommended to use the water thinner as molding resin. I hope it will help you.
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 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 difference between acrylic and resin?
Acrylic: name of polymethyl methacrylate (PMMA), we often say is organic glass. Good transparency and high hardness. It's a kind of plastic.
Q:The difference between resin anchoring agent and cement coil
The cement roll anchor is one of the bonded bolt, which is often used in the initial support of highway tunnel.
Q:Is the resin lens good or glass good?
Say the lens first:The biggest advantage is light resin, glass is 1/3, and, if broken, the resin will not like glass, a glass bar, usually just opened, so relatively safe, especially for children who love slapstick.
Q:What is the chemical name of the resin?
Commonly used are phenolic resins.
Q:What is the density of unsaturated resins?
The density is 1.4-2.2g/cm3Unsaturated polyester resin is a thermosetting resin. When it is heated or initiated, it can be solidified into a insoluble, insoluble polymer network. But the mechanical strength of the polymer is very low, can not meet the use requirements, when reinforced with glass fiber can become a kind of composite material, commonly known as "steel and glass" (English Fiber Reinforced Plastics referred to as FRP). Compared with resin casting, the mechanical strength of glass fiber reinforced plastics has been greatly improved.
Q:What is the use of self - hardening furan resin? Where should I use it?
Properties and applications of furan resins: uncured furan resin has very good miscibility with many thermoplastic and thermosetting resins, so it can be modified with epoxy resin or phenolic resin.
