Silica gel used for gas drying, gas absorption, liquid dehydration, chromatography, catalysts, etc.

Regeneration temperature

Silica gel can be removed moisture by the way of thermal desorption, desorption temperatures as follows:

Type C silica gel≤600℃

Type A silica gel≤200℃

Allochroic silica gel≤120℃

Silica alumina gel≤350℃

Mainly used for drying and moistureproof, may also be used as catalyst carriers, adsorbents, separators and variable pressure adsorbents, etc.

Type B Silica Gel

Type B silica gel pore structure is between silochrom and fine-pored silica gel.

Mainly used for liquid absorbent, humidity regulator, desiccant, catalyst, catalyst carrier, spices carrier, silica sand, pet bedding, whitening agent and used as the raw material of chromatography silica gel and other fine chemical products.

Silica Gel Cat Litter

Silica gel cat sand actually is Type C silica gel

Silica gel cat litter is non-toxic and pollution-free, it is hard to be broken, can inhibit bacterial from growing. Yuanying cat litter has the following merits:

1. It can absorb and hold the urine and feces odor and keep your room air fresh.

2. It can completely absorb the cat urine immediately although adsorption liquid is over 80% of its own weight and still can keep its appearance dry.

3. 4 lbs cat litter for one cat can be used for one month.

4. It can inhibit bacterial from growing.

Cat litter itself is white, can be made more colors according to user requirements, can also be added fragrances. Common fragrances include rose, lavender, jasmine, lemon, sweet-scented osmanthus, ocean, apples, oranges, strawberries, etc. Packing specifications are 3.6L, 3.8L, 4L, 5L, 7.6L, 8L, 10L, 15kg, 20kg and so on. Packaging can be customized according to customer's requirements.

How to use

1. Fill litter box with silica gel cat litter to the lever of 15 inches.

2. Clean up the rubbish after use to keep clean periodically.

3. For more than one cat, you can reduce the period of replacing cat litter in proportion, rather than placing much more cat litter in the box, the proposed way to use one 3.6 L bag is following: a cat, one month, two Cats, about 15 days, three cats, about 10 days.

4. After the solid waste is dehydrated, scoop it out without any litter.

5. Store Cat litter box or silica gel cat litter in clean, non-moisture places, to extend its service life.

Silica Alumina Gel

Molecular formula: mSiO2·nAl2O3·xH2O

Silica alumina gel, which is a kind of special products formed by adding a certain amount of alumina in fine-pored silica gel, different aluminum oxide content has different performance. Yuanying has 17% water resistant silica alumina gel, 0.5% ~ 8% fine-pored silica alumina gel.

17% Silica Alumina Gel

17% silica alumina gel is a kind of fine-pored water-resistant silica alumina gel, generally used as a protective layer for fine-pored silica gel and fine-pored silica alumina gel. It can also be used alone under a high content of free water (liquid water). Although operating system contains liquid water, this product still can achieve a lower dew point.

Mainly used for drying air in the process of air separation; acetylene adsorption in the production process of liquid ammonia and liquid nitrogen; compressed air drying and all kinds of industrial gases drying; as liquid adsorbent and catalyst carrier in the petrochemical industry, electric utility and brewing; as protective layer for common silica gel and silica alumina gel.

0.5%~8% Silica Alumina Gel

The appearance of 0.5 ~ 8% silica alumina gel is slightly yellow, it has good chemical stability, not burning, not dissolved in any solvent. Comparing with fine-pored silica gel, this product has the same adsorption capacity at low relative humidity, but adsorption capacity exceeds 6~10% at high relative humidity, and thermal stability is 150 ℃ higher than fine-pored silica gel (200 ℃), high above. It is very suitable for temperature swing adsorption, separating agent.

It is mainly used for natural dehydration, and light hydrocarbon separation of temperature swing adsorption (PSA), etc. also can be used for petroleum industrial catalyst and catalyst carrier, industrial desiccant, liquid adsorbent and gas separation, etc.

Blue Silica Gel

Blue silica gel can be divided into blue indicating silica gel, color-changing silica gel and blue silica gel. Its appearance is blue or light blue glass-like ball or lump.

Blue silica gel can be regenerated, it will be returned to the original color after heating-dehydration

Related information

Allochroic silica gel is divided into 3 types: blue silica gel, cobalt-free blue silica gel, orange silica gel.

Cobalt-free blue silica gel (yellow to red) contains congo red, congo red itself can be used as an acid-base indicator, colour change interval PH3.5 ~ 5.2, alkali state to red, acid state to violet.

Orange Silica Gel

Orange silica gel mainly used as a desiccant, humidity indicator, indicating dry degree and environmental humidity. Widely used in household appliances, food, clothing, leather, petrochemical industry, pharmaceutical, aerospace, military industry, instrument industry, etc.

Allochroic silica gel is divided into 3 types: blue silica gel, cobalt-free blue silica gel, orange silica gel.
