Ammonium alginate CAS 9005-34-9

Preparation of a new type of antibacterial seaweed fiber.

It is characterized in that the preparation process is as follows: adding alginic acid and a certain amount of compound ammonium salt into a reactor for reaction, preparing ammonium alginate, dissolving ammonium alginate in water to prepare a spinning stock solution with a mass percentage of 3-8%, In an ammonia water coagulation bath containing ammonium chloride and basic copper carbonate, the antibacterial cupric ammonium alginate fiber is obtained by a wet spinning process.

The copper ammonium alginate fiber obtained by the invention has the advantages of soft texture, high moisture absorption, antistatic, safe for human body and no toxic and side effects, and has long-lasting antibacterial function; it can be used to manufacture medical non-woven fabrics, and can also be mixed with cotton, linen, viscose, etc. , Bamboo fiber, silk, Tencel and other blends are used to manufacture high-end clothing and mask base fabrics.

Preparation of flaky carbonaceous heat source for cigarettes.

The method includes the following steps: mixing sodium alginate or ammonium alginate or potassium alginate with carbon powder and water, stirring to form a colloid, wherein the mass ratio of sodium alginate or ammonium alginate or potassium alginate to carbon powder is 1 : 5-45, then extrude the jelly into a thin sheet, fully contact the thin sheet with the calcium salt solution to obtain a solidified product; the solidified product is rinsed and dried to make the water content reach 10-20%, That is, the sheet-like carbonaceous heat source material for cigarettes is obtained.

The invention not only reduces the harm caused by the glass fiber inhaled into the human body, but also improves the flammability of the carbonaceous heat source, and has the characteristics of simple method, short production period and low cost.
