Note :
1 、 The amount of Al 2 O 3 equals to the balance after 100% minus the loss on ignition and the actual amount of impurities listed above.
2 、 The chemical composition listed is calculated according to 1h of dried basis with the temperature ranging 110 o C ± 5 ℃ .
3 、 The impurity composition listed is stipulated according to Provision 5.2 of GB8170 round number requirements.Appearance: Aluminum Hydroxide is white powder or sand-like crystal, with no impurities.
Water contained: The amount of water contained should be less than 14% 。
Extra requirements on Quality: If there is any special requirement on quality from the customer, it should be negotiated and settled down by both sides.
Testing method: the testing method of chemical composition and water contained in Aluminum Hydroxide should be carried out as defined in GB6610.
Chemical properties: the density of Aluminum Hydroxide should be 2340-2390kg/m 3 , as an amphoteric water-containing oxide, Aluminum Hydroxide can be considered either as an alkali or as an acid. It can have chemical reaction with either alkalis or acids.
Main uses: it is mainly used to produce aluminum oxides ,other Aluminum Hydroxide products, various inorganic aluminum salts such as fluoride aluminum, cryolite and vitriolic aluminum, fire retardant and water purifier.
Packing: It is packed in plastic-coated woven bags or woven bags with plastic film, with net weight of each bag equaling to 50 kg. If there is any special requirement from the customer, negotiation and confirmation is needed. The packing of exported products needs to be checked or accord with the requirements from the overseas customers . on the outside package, there mark the content ,name of product, registered brand ,serial number, net weight, supplier and the manufacturing place.
Quality certificates: attached to every product, there is a quality certificate , on which there are supplier, name and brand of product, serial number and weight ,testing result and the marks by the quality supervising institutions ,quality standard number, and the manufacture date.
