never have to resort to using disposable plastic bags when unexpected
The working steel pipe layer generally chooses seamless steel pipe, spiral steel pipe and straight seam steel pipe according to the design and customer requirements. After the surface of steel pipe is treated by advanced shot blasting derusting process, the derusting grade of steel pipe can reach the Sa2 grade of GB8923-1988 standard, and the surface roughness can reach R = micron in the standard. Polyurethane insulation layer: a high-pressure foaming machine is used to inject rigid polyurethane foam solution into the cavity formed between the steel pipe and the outer protective layer at one time, which is commonly known as “pipe foaming”. High density polyethylene protective layer: prefabricated black or yellow polyethylene plastic pipe with a certain wall thickness. One of its functions is to protect the polyurethane insulation layer from mechanical hard material damage, and the other is anti-corrosion and waterproof.
Niu Jianguo, General Manager of Yiyi plastic Industry Co., Ltd., General Manager of Jiaxin Packaging Materials Co., Ltd., founder and Chairman of Bei Ying Ness (Guangzhou) Daily Chemical Co., Ltd., Vice Chairman of Sichuan-Chongqing Chamber of Commerce. From the initial rental of two or three offices to start with packaging cosmetics, to Bei Yingnai (Guangzhou) Daily Chemical Co., Ltd. has become a legend in the development of the industry. After meeting the baptism and precipitation of building bridges over and over again, Niu Jianguo and his enterprises galloped in the time turntable depicted by the years for more than ten years. In the face of the rapid iterative market demand and fierce market competition, they sized up the situation, had insight into the first opportunity, maintained the vitality of innovation and opened up a red sea in the inheritance and iteration of the industry.
As we weigh the pros and cons of small plastic bags, it is important to strike a balance between convenience and environmental sustainability. This balance can be achieved through individual responsibility, by reusing these bags whenever possible or investing in reusable alternatives.

Waterborne polyurethane adhesive refers to the bonding of automobile ceiling, floor, carpet, dashboard, door panel and other interior decoration parts. With water as the dispersion medium, waterborne polyurethane adhesive not only has the excellent properties of solvent-based polyurethane adhesive, but also is non-flammable, non-toxic and pollution-free. It is a new type of adhesive rising under the background of increasing environmental awareness in the world. Its spraying and other processing is convenient, it is thermally activated at a lower temperature, has a good adhesion to the substrate, and has higher initial bonding strength, higher final bonding strength, good moisture resistance, plasticizer resistance and heat resistance.
Do a good job of heat preservation and anti-freezing of temporary water pipes and fire pipes, wrap the exposed pipelines with rubber and plastic sponges and wrap them with waterproof cloth. The faucet is surrounded by brick and filled with thermal insulation sawdust. A drain outlet can be added to the exposed horizontal pipe, and a special person is sent to turn on and off the drain valve.
Furthermore, the Baggu Small Reusable Shopping Bag is designed with a focus on minimizing waste. Its compact size enables it to be easily folded into a small pouch, so you can conveniently store it in your handbag or pocket when not in use. This thoughtful design allows you to carry the bag with you all the time, ensuring that you never have to resort to using disposable plastic bags when unexpected purchases arise.

Plastic sheathed steel polyurethane foam insulation pipe Shuifu-Longdu pipe is a new type of water supply and drainage, anti-corrosion green large diameter pipe, which is more and more widely used in various industries in China. Generally use the combination of internal and external fixed pier, the internal fixed pier is used to ensure that there is no displacement between the working pipe and the outer pipe at the set point. The external fixing pier is used to fix the outer tube, and its main function is to prevent or limit the thermal displacement of the outer casing. The steel sleeve steel may have a large thermal expansion, and the stress of the elbow casing may exceed the limit, so the steel sleeve steel pipe must be equipped with external fixed pier in the project. Polyurethane directly buried insulation pipe is divided into three layers from inside to outside:
