Q:Use of sealant: 0 ° C or more, ± 12.5% of the average width of the joint at the time of sealing, 0 ° C or less, the total amount of ± 5% of the average width of the joint

Q:How to control the concentration and the amount of alcohol: Upstairs said anti. The use of the appropriate concentration of ethanol as a binder (in fact, can only be said to be wetting agent, because you do not add other adhesives), when the granulation of dry particles too much or too hard to consider increasing the ethanol concentration To reduce the concentration of water), if the particles are too soft or too little to reduce the ethanol concentration (equivalent to increase the concentration of water)

Q:How to distinguish between good steak and made from the meat of the "synthetic steak": The meat of the steak is processed deep, and various ingredients are added, and in order to make the meat sticky tightly, the general use of xanthan gum, carrageenan, glutamine aminotransferase such food additives, when you see the ingredients table Such words, you can determine it is stitching beef.

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:In the conservation company has shares, and later to the toll station, now the toll station withdrawal, you can continue to protect the company to work, what can be based on?: Concrete crack treatment, refers to the scientific approach to the repair of concrete cracks in the technology. Concrete cracks generally have three states: static cracks, active cracks, is developing cracks. The choice of concrete crack treatment methods generally to consider the factors: to determine whether the cracks are active or static; repair the main purpose of what? Is to reduce the excessive leakage, so that the cracks at the complete water; whether the need for reinforcement treatment; crack the main reason is what; cracks in the future changes (value and direction) how. - 13 common methods of concrete crack treatment: 1. resin infusion method; 2. surface sealing method; 3. drilling insert method; 4. flexible sealing method; 5. surface additional reinforcement method; 6. grouting method; . Dry insert method; 8. nail method; 9. polymer immersion method (gravity infiltration and vacuum infiltration); 10. Die surface layer and surface treatment method and so on.

Q:Characteristics and Uses of General Purpose AB Adhesive: General AB adhesive characteristics and use: high strength, good toughness, durability, good weather resistance. Widely used in decoration, stone processing, furniture manufacturing, machinery construction, technology toys, electronics manufacturing and other industries. Can be bonded metal, plastic, wood, cement, ceramics and so on.

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:OKorder where to sell the United States He can adhesives, sealants? United States Hernon: He was founded in 1978 in New York's Queens. In 1990 the company moved to Sanford, Florida, an area of 25,000 square feet and with the neighboring industries continue to expand the county.

Hernandy's products are used in the following areas: aerospace, military defense, military other areas, automotive, high-end audio, electronics and other high-tech fields.

Q:What is the use of glass glue and sealant? waterproof: This thing depends on the individual. Glasses are materials that bond and seal various glasses with other substrates. Mainly divided into two categories: silicone rubber and polyurethane adhesive (PU). Silicone rubber sealant - that is, we usually say that the glass glue, and sub-acidic and neutral two (neutral plastic is divided into: stone sealant, anti-mildew sealant, fire sealant, pipe sealant,

Q:How do you define Henkel anaerobic adhesive products?: Anaerobic adhesive sealant (referred to as anaerobic adhesive) is an anaerobic curing characteristics of the adhesive sealant, if the two functions by bonding and sealing points, anaerobic adhesive although there are bonding, but the main The role is sealed lock.
