Raws li ib qho khoom siv dav hlau siv rau hauv kev lag luam niaj hnub, kev txhaj tshuaj cov khoom muaj qhov cuam tshuam ncaj qha rau lawv qhov zoo, thiab lub neej. Kev tshawb fawb kev nthuav tawm tsuas yog tiv thaiv cov khoom deformation thiab kev laus, tab sis kuj tseem txo cov kev hnav thiab kua muag, kom ntseeg tau thaum siv sijhawm siv.
Ua ntej, ib puag ncig tswj yog qhov tseem ceeb hauv kev cia ntawm kev txhaj tshuaj molding cov khoom. Kev txhaj tshuaj cov khoom siv hluav taws xob yuav tsum muab cia rau hauv ib puag ncig nrog qhov ntsuas kub uas tsim nyog thiab av noo. Qhov zoo tshaj plaws cia kub yog 15 qib mus rau 25 degree, thiab cov txheeb ze cov av noo yog tswj tau ntawm 40% thiab 60%. Kev kub dhau los lossis qis qis tuaj yeem ua rau cov khoom siv yas kom nthuav dav thiab cog lus, cuam tshuam rau seem seem. Kev nqus dej ntau dhau tuaj yeem ua rau dej noo ntau thiab deformation, tshwj xeeb tshaj yog rau hygroscopic plastics xws li nylon thiab abs.
Thib ob, zam kev ua tshav ntuj ncaj qha thiab cov roj av hluav taws xob hluav taws xob. Ntev ntev ntawm kev txhaj tshuaj tuaj rau lub teeb muaj zog, nthuav dav cov laus ntawm cov ntaub ntawv yas, ua rau kev sib deev yas, embrittlement, thiab txawm tias tsawg dua hauv lub zog. Yog li no, cia yuav tsum khaws cia rau hauv qhov chaw txias, tsaus thiab them nrog UV {{}} tiv taus ntim yog tsim nyog.
Kev Ntaus Khoom Tsim Nyog thiab Kev Tiv Thaiv yog tseem tseem ceeb. Kev txhaj tshuaj cov khoom siv tau yuav tsum muaj kev tiv thaiv los ntawm kev kub siab lossis nyem kom tiv thaiv kev puas tsuaj lossis kev puas tsuaj saum npoo. Rau cov khoom noj lossis tsis yooj yim, nws raug nquahu kom siv cov ntaub ntawv cushioning (xws li ua npuas ncauj lossis kev tiv thaiv kom ntseeg tau yooj yim thiab tiv thaiv kev puas tsuaj yooj yim thiab tiv thaiv kev puas tsuaj yooj yim thiab tiv thaiv kev puas tsuaj yooj yim thiab tiv thaiv kev puas tsuaj yooj yim thiab tiv thaiv kev puas tsuaj.
Thaum kawg, ib txwm tshuaj xyuas thiab thawj -}} ua ntej- Cov qauv tseem ceeb. Txhaj pwm cov khoom khaws cia rau lub sijhawm ntev yuav tsum tau tshuaj xyuas rau cov cim ntawm noo noo, deformation, lossis laus. Ua raws li cov "thawj {- hauv {}} thawj cov khoom lag luam qub los txo cov kev pheej hmoo loj los txo cov kev pheej hmoo qub los txo cov kev pheej hmoo qub los txo cov kev pheej hmoo qub los txo cov kev pheej hmoo qub los txo cov kev pheej hmoo qub los txo cov kev pheej hmoo loj uas cuam tshuam nrog ntev}} sijhawm cia.
Hauv cov ntsiab lus, kev tshawb xyuas kev tshawb fawb ntawm kev txhaj tshuaj tuaj ntawm ib puag ncig, teeb tsa kev tswj hwm kom ntseeg tau tias cov khoom lag luam nyob rau hauv kev cia thiab muaj kev tsim khoom ntxiv lossis siv cov kev xav tau.
