Thaum ua haujlwm cov khoom siv hluav taws xob evaporation, koj yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thiab ua raws li cov txheej txheem ua haujlwm thiab cov txheej txheem kom raug. Ua ntej, koj yuav tsum xyuas seb cov khoom puas zoo lawm, tom qab ntawd qhib lub tshuab cua sov, thiab tos kom cov cuab yeej ncav cuag qhov kub thiab txias ua ntej yuav ntxiv cov khoom siv. Do tsis tu ncua thaum lub sij hawm noj cov txheej txheem los tiv thaiv cov aluminium alloy los ntawm agglomerating. Ntxuav cov cuab yeej tam sim ntawd tom qab siv thiab ua kom cov cuab yeej huv si thiab huv si.
Brazing kub sib txawv nrog cov khoom sib txawv, txheej txheem thiab khoom siv. Feem ntau hais lus, lub tshav kub-melted roj av stent yuav tsum tau siv ntawm 160 ° C; lub brazed stent nrog zoo ndlwg yuav siv tau ntawm 135 ~ 248 ° C, los yog ua hauj lwm raws li cov khw muag khoom cov lus qhia; cov kua roj av stent rhuab los ntawm thee tar yuav siv tau ntawm qhov kub thiab txias. Kev siv hluav taws xob sib sau ua ke tuaj yeem siv tau.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias qhov kub thiab txias yuav ua rau cov emulsification thiab hydrophobic cuam tshuam thiab yuav tsum tau hloov cov khoom ntawm ncauj tsev menyuam. Yog li ntawd, kev tsim kho thiab siv yuav tsum tau ua nruj me ntsis raws li cov kev cai cuam tshuam los xyuas kom meej qhov project zoo thiab cov kev xav tau.
Kev tu cov cuab yeej siv kuj tseem ceeb heev. Xyuas cov cuab yeej tsis tu ncua kom ntseeg tau tias txhua yam khoom siv ua haujlwm zoo. Yog tias pom muaj kev hnav lossis kev puas tsuaj, hloov lossis kho nws raws sijhawm. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj rau cov khoom siv tu, xws li lubrication, tiv thaiv xeb, thiab lwm yam, txhawm rau txuas lub neej kev pabcuam ntawm cov khoom siv.
Hauv luv luv, nws yog ib qho tseem ceeb heev rau kev khiav lag luam thiab tswj cov khoom siv asphalt melting kom raug los xyuas kom meej cov khoom siv ua haujlwm zoo, txhim kho kev ua haujlwm zoo, thiab txuas ntxiv lub neej ntawm cov khoom siv.
