Kev Ruaj Ntseg Ntawm Lub Hnab Ntim Ntim Tiv Thaiv Ntawm Ntim Sab Hauv

Nrog rau lub zog tensile thiab elongation ntawm so, nws qhia txog lub peev xwm ntawm cov khoom kom tiv taus ncab thaum siv. Yog tias yam khoom no tsis tsim nyog, lub hnab ntim khoom noj yuav ua rau tawg thiab puas thaum siv.

Ib qho ntxiv, nws kuj suav nrog cov khoom thaiv cov pa xws li cov pa permeability; roj tsis kam, tiv tshav kub, tiv taus txias, thiab tiv taus nruab nrab; lub sealing tev quab yuam ntawm lub hnab, lub zog tiv taus thiab poob qis ntawm lub hnab, thiab lwm yam ntsuas. Cov ntsuas no qhia txog kev ua haujlwm ntawm lub hnab ntim khoom noj. Kev ntseeg tau ntawm kev tiv thaiv ntawm lub ntim sab hauv.

Kev ua cov hnab yas zaj duab xis yuav tsum dhau los ntawm cov txheej txheem cua sov, thiab cov yas muaj teeb meem ntawm kev tawg, oxidation, kev puas tsuaj, thiab kev puas tsuaj thaum ua kom sov. Yog li ntawd, thaum ua cov yas zaj duab xis lossis hnab nrog cob, ntxiv cov tshuaj tua kab mob, Cov tshuaj ntxiv xws li cov tshuaj tiv thaiv tshav kub. Qee lub hnab ntim zaj duab xis yuav tsum tau tiv thaiv zoo li qub, tiv thaiv hws, thiab poob siab vim xav tau kev ntim tshuab thiab tshuab lossis cov khoom, yog li cov tshuaj ntxiv xws li cov tshuaj tiv thaiv zoo li qub, cov tshuaj tiv thaiv huab cua, cov roj nplua nyeem, thiab qhib cov neeg sawv cev kuj tseem ntxiv . Tag nrho cov koom haum no yuav tsum tau sim ua ntej los ntawm GB15139&"; Khoom Noj Khoom Nyab Xeeb Toxicology Kev Ntsuam Xyuas Txheej Txheem &"; los ua pov thawj tias lawv tsis muaj tshuaj lom ua ntej lawv tuaj yeem siv tau, tab sis kuj tseem muaj qhov txwv ntawm qhov nyiaj ntxiv. Yog li ntawd, hauv cov khoom lag luam, cov tshuaj qis-molecular-hnyav uas tuaj yeem muab rho tawm, uas yog, cov kua evaporation, lossis yam uas tuaj yeem oxidized thiab tsis zoo, uas yog, kev noj cov tshuaj potassium permanganate, tsis tuaj yeem tshaj qhov tau teev tseg, thiab yog tias nws tshaj nws, nws siv tsis tau. . Yog li, yuav tsum muaj cov qauv kev huv huv rau cov khoom lag luam. Lub hom phiaj yog txhawm rau tiv thaiv kev siv tsis raug thiab siv tsis raug ntawm cov tshuaj ntxiv, thiab txhawm rau ua kom zoo dua tias cov khoom ntim ncaj qha thiab sib cuag nrog zaub mov muaj qib kev huv huv thiab nyab xeeb.
