Product introduction

Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether, made by natural high polymer cellulose as raw material and series of chemical processing. They provide water retention and cohesiveness to mixtures. With special modification, it can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.

It is widely used as thickener, adhesive, water preserving agent, film-foaming agent in building materials, industrial coatings, synthetic resin, ceramic industry, medicine, food, textile, agricultural, cosmetic and other industries.

Q:What do you need to pay attention to using fuel additives?
Add the ratio is generally 1: 1000,1 bottle 50ml additive can be equipped with 50 liters of fuel. In addition, the addition should be depending on the vehicle conditions, models, the vehicle is good for the first time the continuous use of three bottles or so; the situation down, less power vehicles need to use more than 5 bottles until the car condition improved, and then select the box to add once or every Every 1000 km to add once. If the engine is running in good condition, it can be reduced.
Q:Additive function a: R → R is an increasing function .it is continus.why?
Any additive increasing function α: R → R is linear of the form α(x) = α(1)x, hence is continuous. Proof. Suppose that (1) α(x + y) = α(x) + α(y), for any x, y in R, and (2) α(x) ≤ α(y), for any x, y in R, x ≤ y. Applying (1) we have: α(0) = α(0+0) = α(0)+α(0) ==> α(0) = 0 0 = α(0) = α(x+(–x)) = α(x) + α(–x) ==> α(–x) = – α(x), for any x in R α(x – y) = α(x + (–y)) = α(x) + α(–y) = α(x) – α(y), for any x, y in R If n is a positive integer then, for any x in R α(nx) = α(x+x+...+x) = α(x)+α(x)+...+α(x) = nα(x) If n is a positive integer then, for any x in R α(x) = α(n(x/n)) = nα(x/n) ==> α(x/n) = (1/n)α(x) If m, n are positive integers then, for any x in R α((n/m)x) = α(n(x/m)) = nα(x/m) = n((1/m)α(x)) = (n/m)α(x) Collecting the previous results, we have α(qx) = qα(x), for any x in R, q in Q In particular, α(q) = α(1)q, for any q in Q Next I apply (2) to show that α(x) = α(1)x, for any x in R. Fix x in R. Since Q is dense in R, given ε > 0 there are p, q in Q such that p < x < q an q–p < ε. Then α(1)p = α(p) ≤ α(x) ≤ α(q) = α(1)q, so –α(1)(x–p) ≤ α(x) – α(1)x ≤ α(1)(q–x) –|α(1)|ε ≤ α(x) – α(1)x ≤ |α(1)|ε The previous inequality holds for any ε > 0, hence α(x) – α(1)x = 0 bye
Q:What roles do food additives play in the colour and flavour of food and in the preservation of some food items?
Additives in food can increase the nutrition value e.g. added fiber, Vitamin C, Vitamin D etc. Obviously additives are used to preserve foods making them last longer and also to change or enhance the color of foods. I've heard that some supermarkets use additives to keep the outside of fresh meat looking red or pink so it looks fresh longer than it should.
