Yuav ua li cas xaiv iav sealant?

Cov iav sealant yog cov khoom siv rau kev sib txuas thiab sib khi ntau lub iav rau lwm cov substrates.

Muaj ob hom sealant: silicone sealant thiab polyurethane sealant.

Silicone sealant - qhov peb feem ntau hu ua iav sealant, muab faib ua ob hom: acidic thiab nruab nrab (nruab nrab sealant muab faib ua: pob zeb sealant, mildew-proof sealant, fireproof sealant, pipe sealant, etc.). nruab nrog ib rab phom sealant thaum siv nws.Thaum siv nws, nws yog ib qho yooj yim kom tau tawm ntawm lub raj mis sealant nrog rab phom sealant, thiab qhov chaw tuaj yeem txiav nrog spatula lossis ntoo chips.Rau ntau hom sealant, kev kho ceev kuj txawv.Feem ntau, acid sealant thiab nruab nrab pob tshab sealant yuav tsum kho tsis pub dhau 5-10 feeb, thiab nruab nrab variegated sealant yuav tsum tau kho tsis pub dhau 30 feeb.Lub sijhawm kho ntawm iav sealant nce raws li qhov tuab ntawm daim ntawv cog lus nce, thiab lub sijhawm kho yog txiav txim siab los ntawm qhov nruj ntawm lub foob.

Tsis tas li ntawd, thaum lub sij hawm kho cov kua qaub iav sealant, lub volatilization ntawm acetic acid yuav tsim ib tug qaub tsw, uas yuav ploj mus thaum lub sij hawm kho, thiab yuav tsis muaj ib tug peculiar tsw tom qab kho, yog li tsis txhob txhawj txog seb puas muaj ntxhiab tsw. raug tshem tawm.Thaum xaiv, tsis tsuas yog pib ntawm tus nqi, tab sis kuj sib piv qhov zoo.Thiab thaum xaiv iav sealant, nws nyob ntawm koj qhov kev ua tau zoo thiab kev siv.

1.Thov dtsis maj mus yuaviav sealant

Qee cov neeg siv khoom yuav cov iav sealant yam tsis tau nkag siab txog cov kev paub yooj yim ntawm cov khoom, thiab pom muaj ntau yam teeb meem hauv kev siv nws.Xws li: Dab tsi yog qhov txawv ntawm acid sealant thiab nruab nrab sealant?Vim li cas tsuas yog cov txheej txheem nplaum tuaj yeem ua tiav kev sib txuas ntawm cov iav?Vim li cas ib co pob tshab iav sealant hloov xim?Cov khoom siv hauv tsev twg tuaj yeem iav sealant daim ntawv cog lus?thiab lwm yam. Yog tias koj nkag siab txog kev faib tawm, kev siv, kev txwv, kev siv cov txheej txheem thiab lub sijhawm cia ntawm iav sealant ua ntej kev yuav khoom, koj tuaj yeem txuag tau nyiaj thaum tsim kho, txo kev rov ua dua thaum tsim kho, thiab ua kom lub neej ntev ntawm cov iav sealant.

2.Thov dtsis yuav pheej yigiavsealant

Txawm hais tias iav sealant tau siv dav hauv kev tsim kho lossis kho kom zoo nkauj, cov neeg siv feem ntau (qee tus neeg siv qub uas tau siv iav sealant rau lub sijhawm ntev) tseem muab cov khoom pheej yig hauv thawj qhov chaw.Tsuav yog qhov project tog A tsis qhia meej lub iav sealant hom, xaiv tus nqi qis qis yog qhov yuav tsum tau zam, tab sis kev siv cov khoom siv qis qis tsis yog tsuas yog cuam tshuam rau qhov zoo thiab kev pabcuam lub neej ntawm qhov project, tab sis tseem ceeb tshaj, nws tseem ceeb heev. yooj yim ua rau rework, ncua lub sij hawm tsim kho, thiab txawm ua rau lub luag hauj lwm xwm txheej.Txhawm rau kom tau txais txiaj ntsig loj, cov tub lag luam uas tsis paub zoo tuaj yeem ua kom yuam kev ntawm kev ntim khoom, siv cov ntim ntim tuab kom txo qhov hnyav ntawm sealant, thiab hloov cov sealant nrog cov sealant tsis zoo.Cov txiaj ntsig loj heev uas lawv tau txais yog nyob ntawm tus nqi.Ib qib qis iav sealant ntawm tib qhov hnyav tuaj yeem yog 3 zaug pheej yig dua li hom iav sealant, tab sis lub viscosity thiab nro ntawm hom iav sealant yog 3-20 npaug zog dua qib qis iav sealant, thiab lub neej kev pab cuam yog 10-50. sij hawm ntev.Yog li ntawd, engineering units yuav tsum tsis txhob txuag teeb meem, thiab tsuas yog los ntawm kev yuav khoom ib puag ncig lawv tuaj yeem ua kom ntseeg tau qhov zoo ntawm qhov project;cov neeg siv khoom yuav tsum tsis txhob khav theeb rau pheej yig, thiaj li tsis cuam tshuam rau lub neej ntawm kev kho kom zoo nkauj sab hauv.

3.Yog tias koj tsis paub qhov ua tau zoo ntawm iav sealant, tsis txhob siv qhov muag tsis pom.

Muaj ntau hom iav sealant nyob rau hauv kev ua lag luam, nrog rau cov kua qaub iav sealant, nruab nrab huab cua-resistant sealant, silicic acid nruab nrab qauv sealant, silicone pob zeb sealant, nruab nrab anti-mildew sealant, hollow iav sealant, tshwj xeeb sealant rau txhuas-yas panels, tshwj xeeb sealant rau thoob dej yug ntses, tshwj xeeb sealant rau iav loj, tshwj xeeb sealant rau chav dej los tiv thaiv mildew, acid structural sealant, thiab lwm yam., cov neeg siv tsis nkag siab tag nrho cov yam ntxwv ntawm kev faib tawm, kev siv, kev txwv thiab kev tsim kho ntawm iav sealant, thiab feem ntau ntawm lawv. tsis tau kov nws.Qee cov chav nyob lossis cov neeg siv khoom suav nrog iav sealant yog "universal sealant".Tom qab ib xyoos, lawv pom tias qhov chaw siv lub iav sealant tau poob los yog hloov xim, yog li lawv tshawb xyuas qhov kev siv ntawm iav sealant.Nws hloov tawm tias cov khoom siv hauv tsev sib txawv yuav tsum xaiv ntau hom iav.sealant.Yog li ntawd, tsis txhob dig muag siv iav sealant yog ib qho ntawm cov xwm txheej rau kev xaiv cov khoom tsim nyog.

4.Ua tib zoo saib rau hnub tsim khoom

Kev ua tau zoo ntawm txhua yam ntawm cov iav sealant uas tas sij hawm tau txo qis heev.

5. Sim los ntawm tes.

Tshem tawm ib feem ntawm lub iav sealant overflowing ntawm ntug ntawm cov roj hmab stopper, pinch thiab rub nws maj mam nrog koj txhais tes.Yog hais tias nws yog tag nrho ntawm elasticity thiab mos, qhov zoo yog zoo.Yog hais tias nws yog ib qho nyuaj thiab nkig, qhov zoo ntawm sealant yog questionable.

6.Tom qab kho tag nrho

① Saib qhov gloss nto.Cov iav kho kom zoo tag nrho, qhov zoo dua thiab ua kom zoo dua qhov gloss, qhov zoo dua qhov zoo.tus

② Txheeb xyuas qhov pores.Pores qhia tias cov tshuaj tiv thaiv tsis sib xws, thiab tej zaum yuav muaj teeb meem nrog cov qauv.tus

③ Xyuas seb qhov chaw yog oily.Yog tias muaj roj to, nws txhais tau hais tias txhawm rau txo tus nqi, cov roj dawb ntau dhau ntxiv thiab qhov zoo tsis zoo.

④ Tshawb xyuas cov hmoov ntawm qhov chaw.Yog hais tias nws yog hmoov, muaj ib yam dab tsi tsis ncaj ncees lawm nrog cov mis.tus

⑤ Saib qhov adhesion.Tshem tawm cov iav sealant ntawm lub substrate los ntawm tes, yog tias nws tuaj yeem tawg tau yooj yim, nws txhais tau tias qhov adhesion tsis zoo txaus.Ntawm qhov tsis sib xws, nws yog qib siab tshaj plaws.

⑥ Sim hloov pauv.Tshem ib feem ntawm lub iav sealant thiab rub nws los ntawm tes.Lub elongation ntawm zoo iav sealant tuaj yeem ncav cuag ob mus rau peb zaug ntawm qhov qub.Tom qab tso tes, nws tuaj yeem rov qab mus rau qhov qub ntev.Qhov ntev ntawm elasticity yog khaws cia, qhov zoo ntawm cov sealant.Saib xyuas cov xim thaum rub mus rau qhov txwv, qhov me me ntawm cov xim hloov, qhov zoo dua qhov zoo.

⑦ Saib cov impurities.Buckle lub iav sealant nrog koj txhais tes kom txog thaum nws tawg, thiab xyuas seb lub puab sab hauv yog qhov sib npaug thiab muag heev.Qhov ntau dua thiab muag qhov zoo yog, qhov zoo dua.tus

⑧ Saib kab mob mildew.Qhov ntev nws tsis tau moldy, qhov zoo dua sealant.

⑨ Saib seb nws puas hloov xim.Qhov ntev ntawm cov xim tsis hloov mus rau ib lub sij hawm ntev, lub sealant zoo dua.

⑩ Kev ruaj ntseg zoo.Qhov no suav nrog ntau yam, suav nrog kev tsim, cov khoom siv raw, cov cuab yeej tsim khoom thiab kev ruaj ntseg ntawm cov kws tshaj lij tsim khoom.Cov iav sealant zoo yuav tsum zoo ib yam rau txhua pawg ntawm cov khoom.

7.

Tsis tas li ntawd, nws tau hais meej tias rau tib qib ntawm iav sealant, pob tshab iav sealant muaj kev ua tau zoo dua li lwm cov xim iav sealant;rau tib qib ntawm iav sealant, acidic iav sealant muaj kev ua tau zoo dua li nruab nrab iav sealant.Qhov zoo ntawm cov iav sealant ntim rau hauv tib qhov tshwj xeeb tsis tuaj yeem txiav txim siab qhov zoo, vim tias qhov tshwj xeeb lub ntiajteb txawj nqus ntawm cov mis sib txawv rau ntau lub hom phiaj.Txawm tias cov iav sealant rau tib lub hom phiaj tsis yog qhov siab dua qhov tshwj xeeb lub ntiajteb txawj nqus, qhov zoo dua qhov zoo.
