production methods of Small diameter seamless steel tube
Aluminum vacuum transfer method technology to produce packaging materials due to low cost,Guest Posting good quality and appearance, the wells can be no election probe substrate and with the known world. The process has worldwide patents that the transfer of the zinc oxide technology, the United States to the United Kingdom, Spanish, France, South Korea, Myanmar, Mexico and Brazil and other countries, and payment of technology licenses.
China has been in the large aluminum tubes production of vacuum aluminum and aluminum / plastic composite packaging materials. But development has been relatively slow due to the lack of restrictions of the raw materials Division, is not very extensive range of applications. Aluminum vacuum transfer method, so actively promoting the expansion of the use of the base tree, reducing the cost of packaging and tree Branch, has very important significance to the development of China’s packaging industry, narrowing the gap with developed countries.
Transferring vacuum aluminum is a new technology developed basing on the aluminum vacuum technology and equipments. The titanium dioxide production process can be divided into following steps: coating the carrier membrane separating agent; carrier film is generally a two-way stretch poly the brew membrane (BoPET) and two-way pull polypropylene film (BOPP). Direct vacuum aluminum. Coated with a good separation of the other carrier membrane surface directly vacuum aluminum, aluminum methods and technology and our existing aluminum equipment much the same. The carrier film coated with adhesive, then with the other substrate complex. The composite tree branches and then by drying box for drying. The stratified transfer. After drying, the aluminum layer on the carrier-based tree is firmly drill knot together, and then the carrier membrane
