Major Properties:

1. Physical properties:

A: The appearance is flowing white granular powder, with density of 0.17-0.4g/cm3 temperature lowering to 60, and vitrification temperature being 57, and softening temperature being 60-75.

B: Dissolution: PVB is not soluble in water but in many organic solvents such as alcohol, ester, and ketone. Furthermore, it can mix with many kinds of plasticisers, such as PBT, Fatty Acid Esters and etc. The film formed by them has strong adhesive force, good transparency, water-resistance, and light-resistance. In addition, it can be mix with various resins such as phenolic resin, Urea Resin, epoxy resin, and natural resins and etc.

C: It is resistant to inorganic acid and fat as well as excellent insulation, climate-resistance, water-resistance, and strong aging-resistance.

2. Chemical Properties:

(1)PVB is stable in chemical nature. It can decompose in the acid or alkali.

(2)It starts to decompose when the temperature reaches 100. It decomposes completely at 200-240.

(3)It can undertake Ethylene saponification reaction, hydroxy esterification reaction,

A: Hydrolyzation will occur in dilute acid, when there are some double bonds upon the cross junction between the molecules, with the Acetic Acid hydrolyzes further.

B: It will produce transparent solvent when heated, at the same time aldehyde comes out of it.

C: It can neutralize the free acid, and improve the stability of resin when heated in dilute alkali of 1%.

D. If it boils with alkali of 3%, the acetic acid will further hydrolyze.

E. Salt in it works as catalyst in acetal process. Too much of salt will harm the process for example Zncl2. Cacl2. Alcl2. NaHso3.

4)Reaction with organic matters

A, With the alcohol as solvent, PVB will emit some of aldehyde under the function of phosphoric acid

B. PVB in the glacial acetic acid can produce ester in the reaction with ACETIC ANHYDRIDE with Zncl2 as catalyst.

C. PVB emits lots of hydroxide in the alcohol with acid in it.

Paints: As there are many advantages for PVB such as high binding force, anti-coldness, oil-resistance, anti-wearing, and good anti-corrosion, It has been widely applied in the following aspects:

(1)Wood paints

(2)Metal paints

(3)Bottom paint of metal

(4)Metal ink

(5)Paint of Metal tank.

(6)Dope for braising and plating in vacancy.

(7)Dope for concrete: PVB can improve the anti- wear of paint film.

(8)Dope of water-proof.

(9)Dope for leather.

(10)Varnish protecting dope.

3. Adhesive: PVB contains (hydroxy, acetyl and aldehyde), possessing strong felt nature, so it can be made into all kinds of adhesive. (1)Adhesive of glass: PVB has strong binding force, proper spring and softness. So it can be used to conglutinate glass.

(2)Adhesive of metal.

(3)Conglutination of enameled wire loop.

(4)Heat sealing adhesive.

(5)Adhesive for transfer label trademark.

(6)Film for conglutination.

(7)Press-sensitive adhesive.

(8)Other adhesives.

4. The application in fiber processing:

(1)Smearing

(2)Fiber treatment agent

(3)Printing and dyeing of the fabrics

(4)Arrangement of other resins

(5)Making

Bamboo charcoal's absorptive theory, far infrared function and the characteristic of blocking electromagnetic wave to produce all kinds of fruit deodorant, all kinds of animals deodorant and other different style. Bamboo charcoal can absorb dampness, dry, diminish inflammation, resist bacteria, prevent moth and mildew, absorb peculiar smell including formaldehyde, benzene, sweat, smoke, refrigerator's peculiar smell, etc. Also pruify indoor air, basing on economy and practice, it is rapidly accepted by common peoples.

Our company provide and sale a kind of material that can adsorb and displace gold(Au) from electroplate liquid or solution including cyaniding gold ion ( AuCN-). In some electroplate factory there are a lot of electroplate liquid including cyaniding gold ion ( AuCN-), so we can get a lot of gold (Au) from this electroplate liquid.

This material look like a kind of filter net that have ability to adsorb or displace gold (Au) from solution including cyaniding gold ion( AuCN-), so it can be used to get or withdraw gold(Au) from AuCN- liquid

Operation method:

Put this material (look like filter net) into electroplate liquid for some time, about 3-5 hours later when the electroplate liquid is heat to 50-60 temperature, it can automatically absorb and displace gold(Au) directly from this liquid including cyaniding gold ion( AuCN-)

A piece of material (a piece of net) can adsorb and displace about 10 gram

Gold(Au) from electroplate liquid including AuCN-

Price: USD10.00 a piece (25cm*15cm) can absorb 10g gold from liquid

Minimal quantity: 50 piece USD 500.00

We can provide special discount if you buy a great deal of this material.

The activated carbon is capable of absorbing all types of harmful and corrosive gases. Depending on the conditions, extremely large amounts of hydrogen sulphide, sulphur oxide and other acidic gases can be adsorbed into the carbon. The impregnating agent acts as a catalyst, converting hydrogen sulphide and sulphur oxide compounds as well as other acidic gases into non-volatile, inorganic compounds. This eliminates the possibility of desorption.

The lignin sulfonic acid sodium is a kind of anion surface-active agent made of sulphite whose main raw material is the northeast white pine, following the process of concentration, sugar-exclusion, displacement, etc.

It is used in dyestuffs industry mainly. This product has many kinds of different function, for instance viscidity control, colour adjusted etc., but main function is the scattering of the dyestuffs, this product has hydrophilic and hydrophobia radicel. It creates double membrane layers when interacting with the moisture molecular. Prevent the dyestuffs particle from condensing once again to improve grinding.
