Cellulose microcrystalline Usage And Synthesis:
General Description Odorless, white powdery fibers. Density 1.5 g cm-3. The biopolymer composing the cell wall of vegetable tissues. Prepared by treating cotton with an organic solvent to de-wax Cellulose microcrystalline and removing pectic acids by extration with a solution of sodium hydroxide. The principal fiber composing the cell wall of vegetable tissues (wood, cotton, flax, grass, etc.). Technical uses depend on the strength and flexibility of its fibers. Insoluble in water. Soluble with chemical degradation in sulfuric aicd, and in concentrated solutions of zinc chloride. Soluble in aqueous solutions of cupric ammonium hydroxide (Cu(NH3)4(OH)2).
Reactivity Profile Cellulose microcrystalline is combustible. Incompatible with strong oxidizing agents including bromine pentafluoride, sodium nitrate, fluorine, perchlorates, perchloric acid, sodium chlorate, magnesium perchlorate, F2, zinc permanganate, sodium nitrite, sodium nitrate, sodium peroxide. Nitration with a mixture of nitric and sulfuric acids produces Cellulose microcrystalline nitrates (celluloid pyroxylin, soluble pyroxyline, guncotton) which are flammable or explosive.
Application:
1. Used for tablet binders, disintegrating agents,stabilizer,dilute agent
2. Applicable to the textile, food, paper industries,nutritional supplements

The quality control process:
1)Purchasing
Thorough market research, understand the price of raw materials and performance.To the procurement source to understand fully, and fully guarantee the quality of the procurement of raw materials.
2) Inspection
Four steps: sampling, sample pretreatment, measuring and data processing.
3) Producing
a)Each operator must do self-inspection of products and make the corresponding inspection records.
b)Full-time inspectors through check the operator self-inspection, and review and sign in the corresponding record. Full-time inspection is responsible for inspection of finished product, and make the finished product incoming inspection records.
4) Before selling
Test result can be provided before selling.
Third-party detection institution is allowed if you are not satisfied with test results.
