What is meat adhesive?

Upstairs to the mechanism of action has been generally speaking, so I do not repeat. Meat adhesives are also divided into many kinds, one is the same type of powder is soluble. Dusting for large pieces of meat, water-soluble for small pieces of meat bonding, there is a TG enzyme, but TG enzyme price of more than 300 kilograms or very expensive, greatly increased the cost, especially Chicken products, then the chicken products on the very cheap if the application of TG enzyme binding meat, then the cost of high, small businesses now we do not recommend the application.

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 powder wet with water, the hydration of particles to make its surface with a 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%. Sodium alginate has a pH of about 7.2 in 1% distilled water.

Polyurethane sealant

, One-component polyurethane sealant (paste) is a solvent-free one-component room temperature curing sealant. The sealant is creamy and can be extruded or applied. There is anti-drooping, embedded vertical joints and the top seam is not flowing. The cured layer is rubbery and elastic. Of the metal, rubber, wood, cement components, ceramics, glass and other adhesives. Sealant is used to fill the gap (holes, joints, joints, etc.) of the material, both the bonding and sealing two functions.
