Silicone sealant yog ib qho tseem ceeb ntawm cov nplaum, feem ntau yog siv los khi ntau yam iav thiab lwm yam substrates. Nws yog dav siv nyob rau hauv tsev neeg lub neej, thiab muaj ntau ntau hom silicone sealants nyob rau hauv lub lag luam, thiab lub zog ntawm daim ntawv cog lus ntawm silicone sealants feem ntau qhia. Yog li, yuav ua li cas siv silicone sealant? Nws siv sijhawm ntev npaum li cas rau silicone sealant los kho?
Cov kauj ruam siv silicone sealant
1. Tshem tawm cov dej noo, roj, plua plav thiab lwm yam kuab paug rau ntawm qhov chaw. Thaum tsim nyog, siv cov kuab tshuaj (xws li xylene, butanone) los ntxuav lub ntsej muag, thiab tom qab ntawd siv cov ntaub qhwv huv los so tag nrho cov seem kom nws huv si thiab qhuav.
2. Npog qhov chaw nyob ze ntawm lub interface nrog cov ntaub nplaum yas. Txhawm rau kom ntseeg tau tias txoj kab sib khi ua haujlwm zoo meej thiab huv si.
3.Txiav lub sealing hose lub qhov ncauj thiab nruab lub taw tes nozzle yeeb nkab. Tom qab ntawd raws li qhov loj me me, nws raug txiav ntawm 45 ° Lub kaum sab xis.
4.Nruab cov phom nplaum thiab nias tawm cov khoom siv kua nplaum raws qhov sib txawv ntawm 45 ° Lub kaum sab xis kom ntseeg tau tias cov khoom siv kua nplaum nyob ze rau ntawm qhov chaw ntawm cov khoom siv hauv paus. Thaum lub seam dav ntau dua 15 mm, rov qab gluing yog yuav tsum tau. Tom qab gluing, luas lub npoo nrog ib rab riam kom tshem tawm cov kua nplaum ntau dhau, thiab tom qab ntawd rub tawm daim kab xev. Yog tias muaj stains, tshem lawv nrog ib daim ntaub ntub dej.
5.sealant nyob rau hauv chav tsev kub tom qab 10 feeb ntawm nto vulcanization, ua tiav vulcanization yuav siv sij hawm 24 teev los yog ntau tshaj, raws li lub thickness ntawm txheej thiab kub thiab av noo ntawm ib puag ncig.
Silicone sealant kho lub sijhawm
Silicone sealant sticking lub sij hawm thiab kho lub sij hawm:
Silicone sealant curing txheej txheem yog tsim los ntawm qhov chaw mus rau sab hauv, cov yam ntxwv sib txawv ntawm sealant nto lub sij hawm qhuav thiab lub sij hawm kho tsis zoo ib yam, yog li yog tias koj xav kho qhov chaw yuav tsum tau nqa tawm ua ntej sealant nto qhuav. Ntawm lawv, kua qaub kua nplaum thiab cov kua nplaum nruab nrab pob tshab feem ntau yuav tsum tsis pub dhau 5 ~ 10 feeb, thiab cov kua nplaum nruab nrab feem ntau yuav tsum tsis pub dhau 30 feeb. Yog tias daim ntawv sib cais xim yog siv los npog ib qho chaw, tom qab siv cov kua nplaum, nws yuav tsum tau muab tshem tawm ua ntej daim tawv nqaij tsim.
Lub sijhawm kho ntawm silicone sealant (ntawm chav tsev kub ntawm 20 ° thiab av noo ntawm 40%) nce nrog kev nce ntawm kev sib khi tuab. Piv txwv li, 12 hli tuab acid silicone sealant yuav siv sij hawm 3-4 hnub los teeb, tab sis tsis pub dhau 24 teev, 3 hli txheej txheej tau kho. Yog tias qhov chaw siv lub sealant yog ib feem los yog tag nrho kaw, ces lub sij hawm kho yog txiav txim los ntawm qhov nruj ntawm lub foob. Hauv ntau lub sijhawm sib txuas, suav nrog cov xwm txheej airtight, cov txiaj ntsig kev sib txuas yuav tsum tau kuaj xyuas tag nrho ua ntej siv cov cuab yeej sib txuas. Kev kho yuav qeeb ntawm qhov kub qis (hauv qab 5 °) thiab av noo (hauv qab 40%).
