Kev xaiv cov kua hloov cua sov (HTF) zoo yuav tsum tau sib npaug ntau yam kev siv tshuab thiab kev ua haujlwm kom ua tiav kev ua tau zoo, kev nyab xeeb, thiab kev siv nyiaj tsim nyog. Txawm hais tias qhov kev txiav txim siab zoo li nyuaj, kev tsom mus rau ob peb yam tseem ceeb tuaj yeem ua rau cov txheej txheem ntsuam xyuas yooj yim dua.
Kub ua tus qhia tseem ceeb
Qhov kub thiab txias ntawm koj lub tshuab yog qhov tseem ceeb tshaj plaws rau cov lim dej. Raws li qhov no, cov kua dej feem ntau muaj ob pawg tseem ceeb:
• Kev Siv Kub Siab (>175°C / 350°F): Rau cov xwm txheej nyuaj no, cov kua organic synthetic lossis cov kua silicone raug pom zoo. Lawv tswj tau qhov kub thiab txias txog li 400°C (750°F), muaj qhov siab vapor qis piv rau cov tshuab pa, thiab muaj kev ua haujlwm txhim khu kev qha thoob plaws qhov kub thiab txias dav dav, ua kom ntseeg tau tias muaj kev ua haujlwm kub thiab muaj peev xwm twj tau kub qis.
• Cov Kev Siv Uas Tsis Txhob Kub/Kub Qis Los Yog Tiv Thaiv Kev Khov (≤175°C / 350°F): Cov kua glycol-dej uas raug txwv feem ntau yog cov kev daws teeb meem uas koj xaiv. Cov kua no muab kev hloov pauv cua sov zoo nrog rau kev tiv thaiv kev khov, ua rau lawv haum rau cov kab ke uas raug rau qhov chaw txias dua.
Kev Xaiv Kua Dej Uas Muaj Glycol: Ethylene vs. Propylene
Yog tias cov kua glycol-based sib haum nrog koj cov kev xav tau thermal, qhov kev txiav txim siab tom ntej no cuam tshuam nrog hom glycol puag:
• Cov kua ua los ntawm Ethylene Glycol (EG):Feem ntau nyiam vim lawv cov viscosity qis dua, uas ua rau kev hloov pauv cua sov zoo dua thiab txo cov zog twj. Lawv sawv cev rau kev xaiv pheej yig thiab ua tau zoo rau ntau lub kaw lus kev lag luam kaw.
• Cov kua uas muaj Propylene Glycol (PG):Xaiv thaum muaj qhov tshuaj lom tsawg dua yog qhov tseem ceeb. Cov kua PG feem ntau yog teev nyob rau hauv cov ntawv thov uas muaj peev xwm nyob ze rau kev ua zaub mov, dej haus, lossis hauv qhov chaw uas cov kua xau ua rau muaj kev nyab xeeb lossis kev txhawj xeeb txog ib puag ncig.
Tshaj Kub: Cov Yam Xaiv Ntxiv
Txawm hais tias qhov kub thiab hom kua dej muab qhov pib zoo, kev ntsuam xyuas kom ntxaws kuj yuav tsum xav txog:
• Kev ruaj khov ntawm thermal thiab lub neej ua haujlwm ntawm cov kua dej uas xav tau.
• Kev siv tau lub zog thiab kev ua kom viscosity thoob plaws qhov ntau thiab tsawg ua haujlwm.
• Cov khoom siv sib xws nrog cov khoom ntawm lub kaw lus.
• Kev nyab xeeb, ib puag ncig, thiab cov kev cai lij choj.
• Tag nrho cov nqi ntawm kev muaj, suav nrog kev saib xyuas thiab lub sijhawm hloov roj.
Ib txoj hauv kev xaiv HTF uas siv cov txheej txheem tshwj xeeb—pib nrog cov kev xav tau ntawm qhov kub thiab cov kev txwv tshwj xeeb rau daim ntawv thov—ua kom cov kua dej uas xaiv los txhawb nqa kev ua haujlwm zoo, kev nyab xeeb, thiab kev lag luam ua haujlwm mus sij hawm ntev.
