Packing & Delivery

Packing: 25kg, 50kg,1000kg plastic-lined plastic woven bags or as client’s request.

Delivery: For the sample order we will be able to arrange delivery within 1-4 days on receipt of payment.

                   For the bulk order such as 1 or 10MT the delivery will be within 2-3 weeks on receipt of payment or L/C.


Properties

Properties: a white crystalline powder or flake triclinic axis, shiny crystals, a creamy feel, no odor.Soluble in water, alcohol, glycerol, ethers and essential oils in a weak acid solution. Large for the glass (optical glass, acid glass, heat-resistant glass, glass fiber insulation materials) industry, to improve the heat glass, transparent performance, increase mechanical strength,shorten the melting time.

     Boric acid is actually oxidation boron hydrate (B2O3, 3H2O), for white powder crystallization or three inclined shaft side flake crystallization, have satiny gloss, no odor. Handle Proportion 1.435 (15 °C). Soluble in water, alcohol, glycerin, ethers and oils, aqueous show weakly acidic. The solubility of boric acid in water with temperature and increase, and can change with steam volatile, In the solubility inorganic acid than in water solubility of small. Heated to 70 to 100 °C gradually dehydration generating partial boric acid, 150 ~ 160 °C when coke boric acid, 300 °C generated boric acid anhydride (B2O3).

Applications

Usage:

Boric acid is used extensively for the glass industry, in particular E-glass fibers, but also can not be sbstituted borax.
In the enamel, ceramic industry, products used to enhance the gloss and fastness. Can be used for medicine and wood
preservation. Fungicides can be done in agriculture, pesticides, and trace element fertilizers. Boric acid is produced diboride matrix material, and its metal welding, leather, precious stones, electronics, defense and scientific research departments have widely applied. 

Storage: Seal save. Should be stored in a dry, clean inside storeroom, open air are not, should avoid to rain or moisture.
