Nta Ntawm Cov Khoom Qab Zib Ntau Lawm Kab

'Cov khoom siv yooj yim rau cov khoom qab zib nyuaj yog qab zib, uas suav txog 60% txog 75% ntawm cov khoom qab zib nyuaj. Qhov teeb meem yuav tsum tau daws nyob rau hauv cov khoom qab zib nyuaj yog yuav ua li cas tig crystallized qab zib rau hauv cov khoom amorphous. Tom qab qab zib yaj hauv dej, nws hloov los ntawm lub xeev crystalline mus rau lub xeev amorphous, uas yuav tsum tau dehydrated thiab concentrated. Thaum cov kua qab zib ntshiab yog lub cev qhuav dej thiab muaj zog, qhov kawg tshwm sim tseem yog siv lead ua. Txhawm rau kom tau txais cov tshuaj amorphous lossis non-crystalline, cov tshuaj uas tuaj yeem cuam tshuam crystallization yuav tsum tau ntxiv. Cov tshuaj no tuaj yeem ua rau kom cov kua qab zib ntau ntxiv thiab tiv thaiv cov kua qab zib los ntawm crystallizing thaum nws yog oversaturated. Ntawm qhov tod tes, los ntawm kev ua kom cov viscosity ntawm cov kua qab zib, lub zog molecular ntawm cov kua qab zib los ntawm kev hloov mus rau hauv ib daim ntawv crystalline kuj tuaj yeem ua rau qeeb.
