Blow moulding

Details

北京赛车25 l barrels, holding all kinds of solvents, liquid is used, corrosion resistance

Blow mouldingPrinciple: using high polymer delayed elastic deformation of the temperature dependence of the relaxation time, near the above polymer glass transition temperature of Tf, make polymer semi-finished products (pipe, hollow profiles etc) rapid deformation, deformation, and then keep in a relatively short period of time below the glass transition temperature and crystallization temperature, cooling the molding material deformation was frozen down, this is the principle of viscoelastic hollow molding。Hollow molding principle: using high polymer delayed elastic deformation of the temperature dependence of the relaxation time, near the above polymer glass transition temperature of Tf, make polymer semi-finished products (pipe, hollow profiles etc) rapid deformation, deformation, and then stay in a relatively short period of time below the glass transition temperature and crystallization temperature, cooling the molding material deformation was frozen down, this is the principle of viscoelastic hollow molding。
