It is a multi-cationic hydroxy inorganic polymer flocculant, polynuclear complex body appearance as a pale yellow solid. Notable feature of this product is water effect is obvious, flocculation and sedimentation speed, fast settling, good activity, without additional alkaline additives. Wide range of adaptation PH; low corrosion of plumbing: can effectively remove the color quality SS, COD, BOD and arsenic, mercury and other heavy metals; The products are widely used in drinking water, industrial water and wastewater treatment. The products are mainly used as drinking water, domestic and industrial waste water (such as oily wastewater, printing and dyeing, papermaking wastewater, sewage and other mills) coagulant treatment, as well as highly toxic heavy metals and fluorine-containing waste water treatment; in addition, in the precision casting , leather and so on are also widely used. Poly aluminum chloride characteristics: This product is suitable for a variety of high turbidity in source water, especially for the high turbidity water purification particularly significant effect, it formed alum fast, easy settlement, a suitable source of water PH range wide, corrosive, low labor intensity. PAC use: the best flocculant effect and economic benefits, according to different user source water turbidity, different seasons and different reaction conditions, thousands of tons of water per experimentally determined the optimal dosage to achieve. When using this product dubbed 3% -5% aqueous solution (by weight of the product is calculated) poly aluminum chloride test rules: All indicators project a standard for the type of test items, under normal production conditions, every three at least once a month type test. Wherein the density, alumina, salt degree, not substance, PH value and other indicators of the project should be batch tested. For each batch determination coagulation performance of poly aluminum chloride, 2 drinking water tested by using poly aluminum chloride production plant of Quality Supervision, Inspection departments in accordance with this standard, the manufacturer shall ensure that all manufactured products should be comply with this standard. Each batch of products should be accompanied by quality certificates, including: manufacturer, product name, type, net mass, lot number and date of manufacture, product quality in line with the present standard of proof and this standard number. 3 units have the right to use the provisions of this standard to the received product acceptance. 4 each batch of liquid should not exceed 200t, solids should not exceed 60t. 5 Determine the number of sampling units by GB / T6678 requirements. For bottled liquid product, sampling depth should the sampler barrel, from the upper, middle and lower parts of the sample volume less than 100ML. The sampled product mix, which removed about 800ML, packed in two clean, dry glass bottle, sealed. For bagged solid product, sampling should be inserted into the bag sampler vertical depth of three-quarters of food sampling, product sampling bag which not less than 100g. The sampled product mix, reduced by quartering to about 500g, packed in two clean, dry plastic bottles, poly aluminum chloride sealed. For tank fitted with a halo of liquid products, applications sampler from the tank, middle and lower parts of the sample. Each part of the sample volume less than 250ml will be sampled product mix, remove 800ml, dispensing with two clean, dry plastic bottle, seal glue on the seal of the vial label stating: manufacturer name, product name, batch number, date of sampling, and sampling by name. Bottle for test use, saving three months another bottle for future reference. 6 test results if there is an index does not meet the requirements of this standard, should be re-packing unit from double sampling verification. Verification results one does not meet this standard, the entire batch of products to be ineligible. 7 when the supply and demand sides of the product quality opposition occur, in accordance with the "People's Republic of China Product Quality Law" shall apply. Standards, packaging, transportation and storage of a drinking water with the poly aluminum chloride (solid) packaging by brushing firmly clear signs, including: production plant name, product name, trademark, net mass, lot number and production date, the standard number and GB / T191 provisions "logo 7 Pa wet." 2 drinking water using poly aluminum chloride (solid) Double packaging, the packaging using polyethylene film bags, thickness not less than 0.05mm, the packaging should be greater than the volume of packaging, packaging performance and test methods should be consistent with GB / T8946 regulations. Net weight quality 25kg, 50kg (customer requirements). 3 drinking polyethylene plastic drums with poly aluminum chloride (liquid). When the user needs, drinking water with poly aluminum chloride (liquid) can also be tank shipment. 4 poly aluminum chloride in drinking water in transit should be covered to avoid rain, moisture: and maintain packaging integrity signposted. 5 poly aluminum chloride in drinking water should be stored in ventilated and dry warehouse. Liquid product shelf life of months, solid product shelf life of 12 months.
