Txhais cov nyhuv calendering
Thaum lub sij hawm calendering txheej txheem, thaum cov khoom dhau los ntawm qhov sib txawv ntawm lub calendering cov menyuam, nws yuav raug rau lub simultaneous txiav txim ntawm shearing quab yuam thiab tensile kev nyuaj siab, thiab cov polymer yuav ua raws li cov kev taw qhia calendering, kom cov khoom yog lub cev thiab mechanically anisotropic nta
