Do you know PVA glue / polyvinyl alcohol adhesive making process?
Polyvinyl alcohol is an important chemical raw material for the manufacture of polyvinyl acetate, gasoline pipe and vinylon synthetic fiber, fabric treatment agent, emulsifier, paper coating, adhesives, glue and so on. As a professional manufacturer specializing in pva glue full plant more than 15 years, are you interested in knowing about PVA glue / Polyvinyl alcohol adhesive making process
PVA Glue Manufacturing plant
1) The preparation of initiator and emulsion is respectively in the initiator tank and in the emulsion tank.
2) Add water, emulsion and initiator in proportion into the reactor by pump, stirring it. Then start the heating system to reach the point can be reaction, at the same time, start the cooling system to control the temperature.
3) Next step, control the stirring speed.
4) When the production is finished, filter the materials, then discharge and pack them.
As you can see in the production process, to make PVA glue / polyvinyl alcohol adhesive, some main equipment you need to have such as initiator tank, emulsion tank, glue making reactor, heating system, cooling system, filter, packaging machine and so on. We can design program to meet actual needs of each client. If you want to start pva glue / polyvinyl alcohol adhesive project

*Mixing system for reactor
Mixing system is the core component of reactor, a custom-made stirrer is your key to success. stirrer selection is related with the material’s viscosity, liquid-solid ratio, proportion of liquid, solid’s internal pipe coil etc.
*Main feature
Chemical Processing Machine: stainless steel chemical reaction vessel(reactor) is heated by the external coil or jacket to supply heat transfer conduction oil / steam / water, it is an ideal equipment of low power and high heating temperature and large volume.
A) Reduce the thickness of tank and increase its loading capacity.
B) Increase heat transfer efficiency.
C) Reduce power consumption and cost.
D) Reduce the total diameter of tank and be good for the layout of workshop.
