Acid and alkali resistant fabric core conveyor belt conveying an acid and alkali resistance, corrosion and other conditions of work zone, mainly is suitable for continuous production in the medium of acid and alkali environments. It is resistant to acid and alkali corrosion, into the

Good groove, high production efficiency, relatively low cost, is the general use of fabric core conveyor belt can not be replaced. Acid and alkali resistant fabric core conveyor belt is widely used in acid, alkali and the media about the chemical industry

And heavy industry.

Acid and alkali resistant fabric core conveyor belt core structure selection

Core body with skeleton polyamide fiber or polyester fiber material as a whole skeleton, has the very good toughness, high joint strength, good impact resistance.

Polyamide fiber

Polyamide fiber, American called nylon, nylon, our commodity name of cotton fiber. The basic performance:

(1) high strength, good impact resistance.

(2) high elasticity, good fatigue durability, resistance to deformation of rebound rate of 98%-100%, second only to polyester;

(3) with poor heat resistance, temperature rise, decline in strength fiber contraction, thermal performance than polyester, at 150 ℃ heated 1H, strength maintain 695;

(4) good abrasion resistance, better than other fibers, 4 times higher than that of polyester;

(5) poor fastness to light, because of its large molecules in the amide bond susceptible to the action of light and fracture occurs, resulting in a high degree of polymerization decreased.

Polyester

Polyester fiber, USA commonly known as dacron, our commodity called polyester fiber, basic performance:

(1) slightly lower strength than polyester, wet and dry roughly equal, impact strength is 4 times higher than that of polyamide fiber;

(2) high elasticity, rebound rate of 100%, the wrinkle resistance, fatigue resistance and good best;

(3) and heat resistance and stability, polyester fiber and heat resistance and good stability, the hot air is heated in 150 ℃ for 16 hours, strength loss alone 15%-30%, heating 1000 hours strength loss is 50%, and the

The general fiber under this condition after 200-300 hours namely decomposition;

(4) wear type, second only to cotton fiber;

(5) density and wet back rate, density than other synthetic fiber, the polyester molecular chain is not dear water molecular groups, only a very small moisture absorption ability, so the wet rate is very low;

(6) the chemical stability, polyester not alkali - resistant, under certain temperature conditions, in case of amine compounds can produce degradation;

(7) light fastness, polyester solarization resistant strength retention rate was 30%-40%.

Therefore, different environments, different requirements of polyamide fiber and polyester fiber 2 core body skeleton structure. Polyamide fiber type can be used NN100, NN150, NN200, NN250, NN300,

NN400, NN500, polyester fiber type can be used EP100, EP150, EP200, EP250, EP300, EP400, EP500.
