Cov menyuam yaus ceev ntawm lub zeb qhib yog cuam tshuam nrog lub sijhawm sib xyaw.
Thaum cov menyuam yaus ceev nrawm nrawm, lub zog shear thiab extrusion siab yog loj, qhov kev faib tawm ntawm cov khoom siv roj hmab yuav nrawm, thiab cov sib tov ua tiav tau ua tiav hauv lub sijhawm luv. Txawm li cas los xij, nrawm nrawm nrawm tuaj yeem ua rau cov roj hmab ntau dua, scorch lossis tsis sib xws ntawm cov compound, yog li koj tsis tuaj yeem nce qhov nrawm tsis muaj kev txwv kom luv luv lub sijhawm sib xyaw.
Ntawm qhov tsis sib xws, thaum cov menyuam siv hluav taws xob qeeb qeeb, lub zog shear thiab extrusion ceev yog me me, kev sib txuas qeeb qeeb, thiab cov txheej txheem sib xyaw xav tau ntau lub sijhawm ntxiv. Tab sis qeeb dhau ib txoj kev ceev yuav ua rau cov khoom siv tau tsawg. Hauv kev tsim khoom tiag tiag, nws yog ib qho tsim nyog los sib npaug ntawm cov menyuam cov roj hmab, thiab kom muaj nuj nqis raws li cov khoom siv sib xyaw, yog li kom ua tiav lub hom phiaj zoo thiab kev ua haujlwm siab.
