PMMA recycled materials | SENXIN plastic | recycled materials

Way to identify a common plastic, density method: test all kinds of plastic density liquid as the medium, testing its ups and downs in a liquid medium plastic to roughly identify the categories of plastic, such as a piece of plastic on the water, floating in the water it can be concluded PC renewable materials, materials other than PVC (PVC due to the density of> 1). 2 475 renewable materials, combustion method: the main test of the flame color and smell and smoke emitted by combustion, in general, polyolefin materials combustion flame is blue or light blue more, smell more moderate and light, smoke was white, while the majority of raw materials with benzene or chlorine burn easily after black smoke, strong odors. In addition, as PE, PP a drop burning phenomenon, but no drop burning PVC, etc., but there is a self-extinguishing phenomenon. 3, the optical method: the main test transparency material, commonly used as transparent materials: PS, PC, PMMA, AS; translucent raw materials: PE, random copolymer PP, homo-PP, soft PVC, transparent ABS renewable materials etc., other materials substantially opaque. 4, the color resolution method: In general, raw materials without additives, if itself contains a double bond, the color will display a little yellow, renewable materials such as ABS, due butadiene copolymer, polymer after polymerization still contains double key, thus significantly slightly yellow. HIPS recycled plastic material of the first article inspection steps to confirm whether the product is the law review. Many varieties of exports of plastic products, inspection staff should be good distinction. Required to implement the export inspection of plastic products mainly include the following four: tableware, such as cups, bowls, bottles, forks, placemats, knife; kitchen utensils, water dish, storage tanks, hopper; other household appliances, such as ashtrays, thermos , trash, tablecloths; health and Toiletries renewable materials, such as washing pots, spittoons, soap dish, toothbrush holder, towel hook. HIPS plastic modified second time to get ready application materials. In addition to inspection personnel documents ready for routine inspection and outbound cargo inspection alone, export contracts, export invoices, export packing list, etc. In addition, the settlement letter of credit, and must be accompanied by a letter of credit. Plastics inspection must also provide corporate self-declaration, the material composition of the list and export commodity inspection reports. Third, to ensure consistency between the single permit. Plastic products use more imported raw materials, according to the National Development and Reform Commission, the Ministry of Finance on the "entry-exit inspection and quarantine fees approach" of the relevant provisions of PMMA recycled materials, feed processing required to verify the Customs Manual, qualified inspection fee concessions. When Customs manual verification HIPS renewable materials, often found in the exporting country, contract number and inconsistent inspection. Further investigation, because the contract provided when customs registration of export contracts and inspection is not the same, resulting in commodity inspection, and record exports to countries differ. HIPS plastic fourth modification, inspection single entry must be standardized. "Consignor" Note to fill the foreign trade contract seller; "cargo name," according to foreign trade contracts on the name listed in the fill; "weight" to fill net, do not fill GW; "packaging types and quantities", generally fill xx cartons; consistent document "marks and numbers" and contracts, invoices, etc., unmarked numbers fill "N / M", do not be left blank; the inspection form to stamp, inspection staff autograph.
