Qhov ceev ntawm cov menyuam ntawm lub zeb qhib muaj qhov cuam tshuam tseem ceeb ntawm kev ua tau zoo roj hmab.
Thaum cov menyuam siv cov menyuam khiav nrawm dua, qhov tsim nyog shear zog thiab extrusion siab tuaj yeem tsim tawm, uas yog conducive rau cov kev sib cais ntawm cov compound rau cov roj hmab. Piv txwv li, qhov nrawm yog nyob rau hauv cov roj hmab tsim nyog, kev sib xyaw ua ke tau zoo dua, thiab cov teeb meem ntawm cov teeb meem sib xyaw ua ke tuaj yeem zam tau zoo.
Yog tias cov menyuam yaus txoj kev ceev nrawm heev, lub zog shear yuav loj dhau. Ntawm ib sab tes, nws yuav dhau ntais cov roj hmab molecular, rhuav tshem cov khoom qub ntawm roj hmab, thiab txo cov roj hmab thiab elasticity roj hmab. Ntawm qhov tod tes, nrawm nrawm nrawm tuaj yeem ua rau cov compound tau ceev ceev los ntawm cov menyuam tsis muaj kev sib tsoo, ua rau tsis sib xws dispersion ntawm lub compound.
Thaum cov menyuam siv cov menyuam ua haujlwm qeeb qeeb, lub zog shear thiab extrusion siab tsis txaus. Qhov no yuav ua rau nws nyuaj rau cov compound kom tau sib xyaw puv rau hauv cov roj hmab, thiab nws yuav siv sij hawm sib xyaw ntev dua kom ua tiav cov nyhuv xav tau. Ntxiv mus, kev sib xyaw ntev dhau kuj tseem yuav ua rau poob qis hauv cov roj hmab kev ua haujlwm thiab txo qis kev ua haujlwm.
