Combined use of polyacrylamide and polyaluminum chloride combined use of polyacrylamide and polyaluminum chloride many people say that polyacrylamide and polyaluminum chloride are water purification materials and play a key role in the treatment of water purification, sewage and industrial wastewater. Why are the use methods different? Is there a difference? Polyacrylamide, referred to as PAM for short, is an organic molecule that plays a role in flocculation and sedimentation in water treatment. Therefore, it plays a very key role in some industrial water treatment and domestic drinking water.
Anionic polyacrylamide can be polymerized from acrylamide and anionic monomer. Acrylamide sodium acrylate copolymer is a widely used anionic polymer flocculant
Polyacrylamide (PAM) product introduction: polyacrylamide (PAM) is a water-soluble polymer material, which does not dissolve most solvents. It has excellent inclined plate sedimentation tank performance and can reduce the friction resistance in the middle of the liquid. According to the characteristics of positive ions, it can be divided into non-ionic polyacrylamide, anionic polyacrylamide Cationic polyacrylamide and zwitterionic polyacrylamide.
Common problems of polyacrylamide during transportation are as follows:
1. Aren't they dangerous chemicals?
Polyacrylamide is not a dangerous chemical. Generally, it is not necessary to issue a chemical certificate for logistics transportation. Generally, when delivering in batch, the product batch, product certificate of conformity and operation manual are attached to the delivery of wave purified water. Send several bags of samples by rail or air. According to different regulations, some places need to issue product risk identification reports, etc.
2. Won't it get damp?
The product packaging adopts the form of moisture-proof paper plastic composite bag + lining bag, which can effectively avoid the product loss caused by rainy days during the transportation of polyacrylamide. When choosing delivery logistics, you can also choose a regular and responsible logistics company for consignment.
3. About delivery time.
Generally speaking, after receiving the delivery order, the logistics department arranges polyacrylamide products according to the order content, confirms the delivery location and scheduled delivery cycle with relevant business personnel, and notifies the production department for coordination and the customer to renegotiate the delivery cycle when the product model is insufficient. Usually, wave clean water can be delivered by lightning on the same day.
4. Selection of shipping form.
The common forms of consignment in China are the company's special vehicles, the logistics company's automobile transportation, railway transportation, bus transportation, etc. the logistics company's automobile transportation is mostly used. The company's special vehicles are mainly in the province and a large number of orders. The selection of logistics companies is determined through negotiation with customers or designated by customers. Railway transportation is generally an emergency small order.
