Yuav ua li cas xaiv cov ntaub ntawv yas rau lub tshuab nqus tsev

Mar 28, 2022

Rau lub tshuab nqus tsev txheej tshuab, yas kuj tuaj yeem coated, uas yog ib qho kev txhim kho, tab sis tsis yog txhua yam yas tuaj yeem coated nrog lub tshuab nqus tsev, vim qee cov yam ntxwv ntawm cov yas nws tus kheej yog cov txheej txheem txheej txheem tam sim no tseem unsolvable.

Yog li dab tsi ntawm cov yas tuaj yeem coated nrog lub tshuab nqus tsev vacuum? Txhawm rau ua kom tiav, nws tuaj yeem xaiv hauv peb lub ntsiab lus.

Ua ntej ntawm tag nrho cov, yuav tsum muaj ib tug tej yam affinity ntawm cov yas nws tus kheej thiab txheej txheej. Tsuas yog thaum cov zaj duab xis txheej thiab cov khoom ua haujlwm sib txuas ua ke tuaj yeem tsis yooj yim poob thiab muaj lub neej ntev. Qee cov plastics tsis tuaj yeem ua ke zoo nrog cov khoom siv quav ciab. Cov kws tshawb fawb pom tau hais tias ib txheej ntawm cov xim uas pab txhawb kev sib raug zoo ntawm cov zaj duab xis txheej yog thawj zaug siv rau ntawm cov yas, uas daws qhov teeb meem ntawm adhesion. Cov txheej txheem ntawm ob qho xwm txheej tsis yooj yim nrhiav tau. Tsuas yog qee cov yas tuaj yeem nrhiav tau cov txheej txheem sib xws, tab sis qee cov yas tseem tsis tau pom, thiab cov yas no tsis tuaj yeem coated nrog lub tshuab nqus tsev.

Qhov thib ob, cov yas nws tus kheej yuav tsum muaj qee qhov tsis haum tshuaj tsis haum, uas yuav volatilize thiab khiav tawm raws li qhov kub thiab txias, tab sis raws li cov khoom ua haujlwm uas tuaj yeem coated, cov khoom tsis zoo uas tuaj yeem zam tau raug txwv, yog li thaum xaiv cov khoom yas rau lub tshuab nqus tsev, nws Nws yog ib qho tsim nyog yuav tau xaiv ib qho uas tsis tshua muaj outgassing, yog li kev ntsuas tuaj yeem tswj xyuas qhov cuam tshuam ntawm lub tshuab nqus tsev kawm ntawv thaum lub sijhawm ua haujlwm ntawm lub tshuab nqus tsev. Yog tias muaj ntau ntau, lub tshuab nqus tsev kawm ntawv yuav tsis raug tswj thiab lub tshuab nqus tsev kawm ntawv yuav raug txo, uas yuav cuam tshuam rau cov txheej txheem zoo.

Qhov kawg yog thermal stability ntawm yas. Yas yog siv dav vim nws tuaj yeem tsim cov duab xav tau raws li tus tsim qauv xav tau nyob rau hauv lub xeev rhuab. Qhov no yog thermal deformation, tab sis nyob rau hauv ib puag ncig txheej txheej ntawm lub tshuab nqus tsev txheej, ib tug tej yam kub yuav tsum generated. Yog tias cov yas tsis ruaj khov thaum cua sov, nws yuav deform. Txawm hais tias txheej txheej yog zoo, lub workpiece tau deformed. Txawm li cas los xij, lub melting point ntawm qee cov plastics yog tsawg heev, thiab cov cuab yeej siv tam sim no tseem tsis tau daws, yog li cov yas no tsis haum rau txheej txheej ntawm lub tshuab nqus tsev.

Kev txhim kho tas mus li ntawm lub tshuab nqus tsev txheej tshuab tau ua rau muaj ntau yam ntaub ntawv uas tsis tuaj yeem coated ua ntej kom ua tiav cov txheej txheem, tab sis tseem muaj qee cov ntaub ntawv uas tsis tau tsim cov kev daws teeb meem, tab sis kuv tab tom tos ntsoov rau nws, vim tias kev siv tshuab tsis muaj qhov kawg, thiab ntau yam thev naus laus zis. uas tsis tuaj yeem xav txog ua ntej, tam sim no siv, thiab nplooj ntawv tshiab yuav tsum tshwm sim yav tom ntej.
