Bulk Buy Low Sodium White Fused Alumina Taiwan

Liming is the key process to determine the quality of glue solution(white aluminum oxide). First, the leather materials of different grades are classified according to the grades, and soaked in 1% lime water for 1-2 days to remove the surface stains and make them expand(white aluminum oxide 120 grit). Hydrodegreasing is to take advantage of the impact and mechanical force of water to remove fat and dirt, and make the fiber loose and soft, so as to facilitate ash leaching, which is called boiling gum.

The method is to immerse raw materials in 2-4% lime water solution (15 ℃, pH = 12-12.5) for 15-90 days(pink corundum). After liming, a large amount of water should be used for cleaning and neutralized with dilute hydrochloric acid. Boil the raw materials and water together to convert the collagen into gelatin(aluminium oxide 36 grit). When boiling gum, pay attention to the conditions such as temperature, time, pH value and glue concentration. It is then chopped to increase the contact area at the time of Liming.

Therefore, they are both acidic and alkaline(white corundum). At present, the multi-channel boiling method is generally adopted, that is, in the process of boiling, when the glue reaches a certain concentration, it will be taken out, which is called the first layer of glue, then boiled with supplementary water, and then taken out after boiling, which is called the second layer of glue, and so on(brown fused alumina grit). The quality of the first layer is good, which is gelatin, followed by the second layer and the last layer.

Amino acids contain not only basic amino-h2, but also acid hair shop-co0h(brown aluminum oxide blast media). The finished product is the boiled glue solution, which is filtered to remove impurities, concentrated, then condensed, sliced, dried, crushed and packed. However, the precipitate does not lose the ability to return to the solution(aluminium oxide grit 24 mesh). Generally, 5-6 layers of rubber can be used for leather with good quality. The freezing point (the critical temperature for gel to gel) is 22 ~ 25 ℃.

There are many production methods of animal glue, including alkali method, acid method, salt alkali method and enzyme method, etc.(brown fused alumina price), but the most important one is alkali method, taking skin glue as an example.The normal moisture content of finished rubber is about 15%. The production method of bone glue is more complicated than skin glue, but the basic principle is the same, so we will not repeat it here(black silicon carbide suppliers). Except glycine, they are asymmetric and have optical isomerism.

They are amphoteric electrolytes(white fused alumina). If the base number of ammonia is the same as that of carboxy, they are neutral amino acids. If there are many amino acids, they are alkaline; If there are many carboxyl groups, they are acidic. In the acidic medium, amino acids are in the form of cations with positive charge(corundum sand). In the alkaline solution, they are in the form of anions with negative charge. All proteins have the optical activity of turning the polarized light to the left.

Most proteins are amorphous in nature(black corundum). They are colloidal in solution and have many common properties, which are closely related to the properties of amino acids. They are soluble in alkali, a few proteins are soluble in water and dilute salt solution, but they are insoluble in organic solvents, such as anhydrous ethanol ether, benzene, etc(black silicon carbide factory). Amino acids are colorless crystals, soluble in water, insoluble in ketones, benzene, and other organic compounds.
