Kev txhaj tshuaj cov khoom siv tau dav siv hauv kev lag luam niaj hnub, suav nrog cov khoom siv hauv nruab nrog, suav nrog cov khoom lag luam niaj hnub, thiab qhov chaw tsheb. Kev siv thiab kho kom raug yog qhov tseem ceeb los xyuas kom muaj kev ua tau ruaj khov thiab txuas ntxiv rau lawv lub neej pabcuam. Nov yog qee cov lus qhia tswv yim.
1. Zam kev kub heev
Qhov kub tsis kam ntawm kev txhaj tshuaj moulded cov khoom sib txawv raws cov khoom (piv txwv, PP, ABS, PC, thiab lwm yam). Zam kev ntev ntev los yog qhov kub tsawg dua li cov khoom siv tsis taus ntau yam. Piv txwv li, zoo tib yam plastics yuav deform ntawm high kub, thaum thaum tsis tshua muaj kub uas lawv yuav raug nplawm, ua rau tawg lossis puas tsuaj. Nws raug nquahu kom yim sab laj rau cov ntaub ntawv cov ntaub ntawv kom paub meej tias cov khoom siv tau ntsuas kub.
2. Tiv thaiv cov tshuaj corrosion
Ntau cov khoom moulded yog rhiab rau cov tshuaj lom neeg xws li cov kua qaub, alkalis, thiab cov kuab tshuaj organic. Hu rau detergents, roj, lossis corrosive chemical tuaj yeem ua rau muaj kev tsis txaus siab, o, lossis txawm muaj kev cuam tshuam. Yog tias muaj kev sib tiv thaiv nrog cov tshuaj yeeb dej num zoo li no, nws raug pom zoo kom xaiv cov khoom siv tshuaj lom neeg ntau dua (piv txwv li, PVDF) lossis kom huv si thiab qhuav cov khoom kom sai tom qab siv.
3. Ua kom tu thiab tu
Rau kev ntxuav txhua hnub, siv daim ntaub mos muag thiab xab npum nruab nrab. Zam txhob siv cov phuam qhwv caj dab lossis cov ntaub plaub hlau kom tsis txhob ua rau muaj kev puas tsuaj saum npoo av lossis cov khawb. Kev txhaj tshuaj - moulded seem uas siv rau lub tsev ua haujlwm ntev (xws li tshuaj ntsuam xyuas cov kab nrib pleb lossis kev soj ntsuam tuaj yeem ua rau lawv lub neej pabcuam.
4. Tsim Nyog Loading thiab zam dhau kev tshaj lij
Lub zog ntawm kev txhaj tshuaj - moulded seem yog nyob ntawm lawv cov phab ntsa tuab thiab khoom siv. Kev muab nyiaj ntau dhau los yog khoov ntawm kev tsoo. Piv txwv li, nyias -} cov khoom siv cov khoom siv hnyav, thiab cov clips thiab cov pob qij txha yuav tsum ua kom tiv thaiv kev puas tsuaj los ntawm kev ntxhov siab.
Ua raws li cov lus qhia no yuav tsis tsuas txhim kho kev ua tau zoo ntawm kev txhaj tshuaj} moulding tsis tseem ceeb thiab kua muag, ua kom muaj txiaj ntsig zoo hauv ntau cov ntawv thov.
