Yog tias silicone sealant muaj teeb meem zoo, nws yuav ua rau cov dej xau, cua nkag thiab lwm yam teeb meem, uas yuav cuam tshuam rau huab cua nruj thiab dej nruj ntawm lub qhov rooj thiab qhov rais.
Kev tawg thiab dej ntws los ntawm qhov tsis ua haujlwm ntawm lub qhov rooj thiab qhov rais sealant
Yog li yuav ua li cas peb xaiv lub sealant zoo rau lub qhov rooj thiab qhov rais?
1. Xaiv cov khoom kom raug raws li cov qauv
Thaum xaiv cov sealant, yuav tsum tau them nyiaj mloog tsis tsuas yog rau tus qauv nws ua tau raws li, tab sis kuj rau nws cov theem hloov chaw.Kev xaav muaj peev xwm yog qhov ntsuas tseem ceeb tshaj plaws los ntsuas qhov elasticity ntawm sealant.Qhov siab dua qhov muaj peev xwm hloov chaw, qhov zoo dua elasticity ntawm silicone sealant.Kev ua thiab kev teeb tsa ntawm lub qhov rooj thiab qhov rais yuav tsum xaiv cov khoom uas muaj peev xwm hloov tsis tau tsawg dua 12.5 kom ntseeg tau tias huab cua nruj thiab dej nruj ntawm lub qhov rooj thiab qhov rais.
Thaum lub sij hawm kev teeb tsa thiab siv lub qhov rooj thiab qhov rais, qhov sib txuas ntawm cov sealant zoo tib yam thiab cov cement pob zeb feem ntau yog qhov phem tshaj qhov uas nrog cov txhuas profile lossis iav ntawm qhov rooj thiab qhov rais.Yog li ntawd, nws yog qhov tsim nyog los xaiv cov khoom ua raws li JC / T 881 raws li lub sealant rau kev teeb tsa lub qhov rooj thiab qhov rais.
Cov khoom uas muaj kev hloov pauv siab muaj peev xwm tiv taus kev sib koom ua ke hloov pauv.Nws raug nquahu kom xaiv cov khoom uas muaj kev hloov pauv siab kom deb li deb tau.
2. Xaivsiliconesealant khoom kom raug raws li lub hom phiaj
Npog thav duab qhov rais thiab zais thav duab qhib kiv cua xav tau cov qauv sealant los ua lub luag haujlwm ntawm kev sib koom ua ke.Silicone structural sealant yuav tsum tau siv, thiab nws txoj kev sib txuas dav thiab tuab yuav tsum ua tau raws li cov qauv tsim.
Thaum lub sij hawm installation ntawm lub qhov rooj thiab qhov rais, lub sealant rau pob zeb pob qij txha los yog cov pob qij txha nrog pob zeb ntawm ib sab yuav tsum yog cov tshwj xeeb sealant rau pob zeb uas ua tau raws li tus qauv ntawm GB / T 23261.
Fireproof sealant yog tsim rau fireproof qhov rooj thiab qhov rais los yog sab nraud qhov rooj thiab qhov rais ntawm lub tsev uas yuav tsum tau hluav taws kev ncaj ncees.
Nyob rau hauv daim ntawv thov qhov chaw tshwj xeeb rau kev tiv thaiv pwm, xws li chav ua noj, chav dej huv thiab qhov chaw tsaus thiab ntub dej, kev sib khi ntawm lub qhov rooj thiab qhov rais yuav tsum siv cov pwm pov thawj sealant.
3. Tsis txhob xaiv silicone sealant uas muaj roj!
Tam sim no, kev ua lag luam yog tag nrho ntawm cov roj puv qhov rooj thiab qhov rais sealants, uas muaj cov roj ntxhia ntau thiab muaj kev laus tsis zoo, uas yuav ua rau muaj ntau yam teeb meem zoo.
Silicone sealant sib xyaw nrog cov roj ntxhia hu ua "roj ntim silicone sealant" hauv kev lag luam.Mineral roj belongs rau saturated alkane petroleum distillation.Vim tias nws cov qauv molecular txawv ntawm cov silicone, nws qhov kev sib raug zoo nrog silicone sealant system tsis zoo, thiab nws yuav tsiv thiab nkag mus rau ntawm silicone sealant tom qab lub sijhawm.Yog li ntawd, "roj filling sealant" muaj qhov elasticity zoo thaum xub thawj, tab sis tom qab siv rau ib lub sijhawm, cov roj ntxhia tau hloov pauv thiab nkag mus los ntawm cov sealant, thiab cov sealant yuav ntsws, tawv, tawg, thiab txawm tias muaj teeb meem ntawm tsis sib txuas.
Feem ntau tus nqi qis silicone sealants nyob rau hauv kev ua lag luam muaj cov roj ntxhia, thiab cov ntsiab lus ntawm silicone yooj yim polymer yog tsawg dua 50%, thiab qee qhov tseem tsawg dua 20%.
Yog hais tias lub sealant ntawm cov roj filling qhov rais tiv tauj nrog lub iav insulating, cov roj ntxhia uas muaj roj yuav txav mus los thiab nkag mus rau hauv cov iav insulating, uas ua rau tawg ntawm lub sealing butyl roj hmab ntawm cov iav insulating thiab roj ntws.
Xaiv cov khoom zoo sealant.Txawm hais tias tus nqi ntawm sealant yuav nyob rau theem pib yog me ntsis siab dua, nws qhov kev ua tau zoo tuaj yeem khaws cia rau lub sijhawm ntev yam tsis muaj teeb meem zoo.Xaiv tus nqi qis qis "roj filling sealant", txawm tias tus nqi pheej yig, tus nqi pib pib qis dua me ntsis;Txawm li cas los xij, tom qab muaj teeb meem tshwm sim, cov nqi kho mob tom qab, cov nqi khoom lag luam, cov nqi ua haujlwm, cov khoom lag luam poob, thiab lwm yam thaum lub sij hawm rov ua hauj lwm yuav yog ob peb zaug los sis txawm kaum ob lub sij hawm tus nqi ntawm sealant nws tus kheej;Tsis tsuas yog nws tsis txuag nyiaj, tab sis nws ntxiv teeb meem ntau rau cov neeg siv.
