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.

Gypsum Adhesive

Gypsum adhesive is used to attach gypsum plasterboard and cornice to masonry wall vertically. Gypsum adhesive is also used in laying gypsum blocks or panel and filling gaps between blocks.

Because fine hemihydrate gypsum is the main raw material, gypsum adhesive forms durable and powerful joints with strong adhesion.

The primary function of HPMC gypsum adhesive is to prevent material separation and to improve adhesion and bonding. Also it helps in terms of anti-lumping.

Q:Is there a difference in the additives that chevron and shell use in their REGULAR gas?
The additives in both of these gases is designed to clean your engine valves of gunk. Gunk is a thick, black dirty kind of soot that collects on the engine valves which can cause the engine to run poorly after a while and eats more gas because they are dirty. They are not better gas, but it is the cleaning additives that are supposed to make them better for your engine because they keep the INSIDES of the engine cleaner. I have found that by using them, occasionally, they do clean the engine, keep it running smoother, and give just a bit better gas mileage. They cost more money, and so I use them and fill up with them from empty, if I feel my engine is getting a bit sluggish or the gas mileage is suffering, and they usually help. You do not need to use them 100% of the time, but it is good occasionally, when the tank is empty to fill it with Chevron or Shell, and then maybe a second tank full. It is also always better to stick to name brand, well know, gasoline. Cheap gas has no additives to clean your engine, and it can also be dirty which can clog your fuel pump, leading to engine failure.
