High Grade Flexible Polyurethane Foam Material

Q:Use of sealant: Construction surface should be clean, hard, dry and no oil, grease and surface dirt such as release agent, curing film and hydrophobic agent. Thoroughly remove all loose particles and ash to search for dust

Q:How does ethyl cellulose act as a large particle binder: Ethyl cellulose due to its water insoluble, mainly for tablet adhesives and film coating materials, can also be used as a skeleton material blockers, the preparation of various types of skeleton sustained-release tablets; used as a mixture of materials preparation coating Sustained release tablets, sustained-release pellets; used as encapsulation materials to prepare sustained-release microcapsules, so that the sustained release of efficacy, to avoid the role of some water-soluble drugs prematurely; can also be used for a variety of pharmaceutical formulations for dispersant, , Water-retaining agent, to prevent the deterioration of drugs and improve the safe storage of tablets.

Q:Polyurethane sealant: One-component polyurethane sealant is used to fill the gap (holes, joints, joints, etc.) materials, both bonding and sealing two functions. Polyurethane sealant and silicone sealant, polysulfide sealant composition of the current high-grade sealant of the three major varieties.

Q:Where the production of acrylic surface hardening agent manufacturers, it is best to tell me about the performance of hardening agent and hardening process: Q Jiangmen Cato Chemical Co., Ltd. is a Sino-foreign joint venture which integrates research and production of advanced chemical building materials. The company's production base covers an area of 30,000 square meters, adjacent to the western coastal highways, water and land transportation, geographical advantages, and has strong scientific research and technology, with more than Dr., master of chemical professional researchers, product research And development, and with a number of foreign chemical building materials research institute long-term cooperation, the application of advanced technology, and continuously improve the product quality, leading the trend, driving the market.

Q:Common types of glue?: This kind of sealant rubber as the base material, commonly used rubber polysulfide rubber, silicone rubber, polyurethane rubber, chloroprene rubber and butyl rubber.

Q:How to do 888 paint?: Is the most high-end products Dulux pearl light A888 it?

Q:703 adhesive sealant can be used for mobile phone screen: 703 is used for electronic product bonding seal, the phone screen is not very appropriate.

Q:Will the kind of adhesive soluble in water (preferably powder), melting temperature of about 800 degrees, was neutral or weak alkaline, thank you!: Alginate is slightly soluble in water and insoluble in most organic solvents. It is dissolved in alkaline solution, so that the solution is viscous. Sodium alginate alginate is hygroscopic and the amount of moisture contained in the equilibrium depends on the relative humidity. The dried sodium alginate is stored fairly stable in a well-sealed container at 25 ° C and below. Sodium alginate solution is stable at pH 5 to 9. The degree of polymerization (DP) and the molecular weight are directly related to the viscosity of the sodium alginate solution, and the decrease in viscosity during storage can be used to estimate the degree of sodium alginate de-polymerization. High degree of polymerization of sodium alginate stability is less than the degree of polymerization of sodium alginate. It is reported that sodium alginate can be catalyzed by proton hydrolysis, which depends on time, pH and temperature. The propylene glycol alginate solution is stable at room temperature at pH 3 to 4; when the pH is less than 2 or greater than 6, the viscosity will decrease even at room temperature. The sodium powder is wet with water and the hydration of the particles makes the surface sticky. The particles are then quickly bonded together to form clumps, and the agglomerates are slowly and completely hydrated and dissolved. Alginate is more difficult to dissolve in water if it contains other compounds that compete with alginate for hydration. Water in the sugar, starch or protein will reduce the rate of sodium alginate hydration, mixing time necessary to extend. A monovalent cation (such as NaCl) also has a similar effect at concentrations above 0.5%. The pH of sodium alginate in 1% distilled water was about 7.2....

Q:What kind of "adhesive" ah? For example: PVA, bentonite, what kind of?: Casting with it? In addition to clay there are water glass, resin, etc., you can find a website on the casting process to see.

Q:What happens to concrete cracks in bridge construction?: Flexible sealing method is usually the active cracks into sports joints is a more appropriate way. Open a groove along the edge of the crack and fill in the appropriate flexible material. Use the isolation layer at the bottom of the joint.
