Los ntawm kev xav ntawm cov chaw tsim khoom, qhov teeb meem ntawm kev laus cov khoom siv roj hmab
Tsis muaj teeb meem dab tsi, muaj lub neej ncua, thiab yog li roj hmab. Tom qab siv sijhawm ntev, yuav muaj teeb meem kev laus. Yog li dab tsi yog qhov tshwm sim ntawm kev laus rau cov khoom siv roj hmab? Qhov laj thawj yog dab tsi? Puas muaj kev daws teeb meem? Tom ntej no, kuv yuav tham txog nws los ntawm qhov kev xav ntawm cov neeg tsim khoom
Yog li dab tsi yog aging, thiab dab tsi yog nws manifestations? Cov kev ua tau zoo tshwj xeeb yog softening, hardening, stickiness, thiab lwm yam, piv txwv li, log tsheb yuav tawg tom qab lub sij hawm ntev, uas kuj yog ib qho kev tshwm sim ntawm kev laus, thiab piv txwv li, cov khoom tau siv rau lub sij hawm ntev ua ntej nws yuav ncab thiab cuam tshuam resistant. Cov no kuj muaj nyob rau hauv. Nws yog qhov poob ntawm lub cev thiab tshuaj lom neeg ntawm cov khoom siv roj hmab, uas yog hu ua roj hmab aging.
Yog vim li cas? Hauv kev nthuav dav, raws li cov khoom siv roj hmab, nws tuaj yeem tiv nrog oily, corrosive thiab lwm yam kua. Nws kuj tseem tuaj yeem siv los ua lub foob pob thiab cushioning, lossis log tsheb, thiab lwm yam, los yog siv tau. Txhawm rau tiv nrog cov kab mob thiab lwm yam kab mob. Nws tuaj yeem pom tau tias vim nws qhov kev ua tau zoo thiab kev lag luam, nws tau siv ntau qhov chaw, uas tseem ua rau nws muaj hnub nyoog yooj yim, uas tuaj yeem muab faib ua peb yam: physics, chemistry, thiab biology.
Tsis tas li ntawd, puas muaj txoj hauv kev los tiv thaiv kev laus ntawm cov roj hmab? Hmoov tsis, qhov no tsis muaj tseeb. Ib yam li kev yug me nyuam, kev laus, kev mob nkeeg thiab kev tuag, cov xov tooj ntawm tes yuav daig tom qab siv sijhawm ntev. Nws yog inevitable. Txawm li cas los xij, peb tuaj yeem ncua kev laus. Peb tuaj yeem pib los ntawm ob yam: ib qho yog zam, thiab lwm qhov yog cuam tshuam.
Kev zam yog sim zam kom tsis txhob muaj qhov ua rau muaj kev laus thaum cov khoom siv roj hmab siv. Piv txwv li, yog tias cov khoom siv roj hmab tsis tiv taus cov roj, lawv yuav tsum tsis txhob kov cov roj. Cov khoom uas tsis tiv taus qhov kub thiab txias yuav tsum tsis txhob raug rau qhov kub thiab txias ib puag ncig.
Kev cuam tshuam yog hais txog kev nquag ntxiv qee yam tshuaj tiv thaiv kev laus thaum lub sijhawm tsim khoom, xws li thermal stability, antioxidants, thiab lwm yam.
