Cov roj hmab silicone - yam peb feem ntau hu ua cov roj hmab iav, muab faib ua ob hom: acidic thiab neutral (cov roj hmab nruab nrab muab faib ua: cov roj hmab pob zeb, cov roj hmab tiv taus pwm, cov roj hmab hluav taws, cov roj hmab yeeb nkab, thiab lwm yam). Feem ntau, cov roj hmab iav yuav tsum muaj rab phom roj hmab thaum siv nws. Thaum siv nws, nws yooj yim kom tau nws tawm ntawm lub raj mis roj hmab nrog rab phom roj hmab, thiab qhov chaw tuaj yeem txiav nrog spatula lossis ntoo chips. Rau ntau hom roj hmab sib txawv, qhov ceev kho kuj txawv. Feem ntau, cov roj hmab acid thiab cov roj hmab pob tshab nruab nrab yuav tsum tau kho kom zoo hauv 5-10 feeb, thiab cov roj hmab sib txawv nruab nrab feem ntau yuav tsum tau kho kom zoo hauv 30 feeb. Lub sijhawm kho ntawm cov roj hmab iav nce ntxiv raws li qhov tuab ntawm daim ntawv cog lus nce ntxiv, thiab lub sijhawm kho yog txiav txim siab los ntawm qhov nruj ntawm lub foob.

Tsis tas li ntawd xwb, thaum lub sijhawm kho cov kua qaub iav sealant, qhov ua rau cov kua qaub acetic yuav ua rau muaj ntxhiab tsw qab, uas yuav ploj mus thaum lub sijhawm kho, thiab yuav tsis muaj ntxhiab tsw qab tom qab kho, yog li tsis txhob txhawj txog seb puas tuaj yeem tshem tawm cov ntxhiab tsw. Thaum xaiv, tsis yog pib ntawm tus nqi xwb, tab sis kuj piv qhov zoo. Thiab thaum xaiv cov kua qaub iav sealant, nws nyob ntawm koj qhov kev ua tau zoo thiab kev siv.

1. Thov dtsis txhob maj mus yuavcov tshuaj nplaum iav

Muaj ib txhia neeg siv khoom yuav cov tshuaj nplaum iav yam tsis nkag siab txog cov khoom siv, thiab pom ntau yam teeb meem thaum siv. Xws li: qhov txawv ntawm cov tshuaj nplaum kua qaub thiab cov tshuaj nplaum nruab nrab yog dab tsi? Vim li cas tsuas yog cov nplaum uas muaj cov qauv thiaj li ua tau cov qauv sib txuas ntawm cov iav?

Yog tias koj nkag siab txog kev faib tawm, kev siv, kev txwv, cov txheej txheem siv thiab lub sijhawm khaws cia ntawm cov tshuaj nplaum iav ua ntej yuav, koj tuaj yeem txuag tau nyiaj thaum lub sijhawm tsim kho, txo kev ua haujlwm dua thaum lub sijhawm tsim kho, thiab ua kom lub neej ua haujlwm ntawm cov tshuaj nplaum iav ntev dua.

2. Thov dtsis txhob yuav pheej yigiavcov tshuaj nplaum

Txawm hais tias cov tshuaj nplaum iav tau siv dav hauv cov haujlwm tsim kho lossis kho kom zoo nkauj, feem ntau cov neeg siv (qee tus yog cov neeg siv qub uas tau siv cov tshuaj nplaum iav ntev) tseem muab cov khoom pheej yig tso rau hauv thawj qhov chaw. Tsuav yog tus neeg ua haujlwm A tsis qhia meej txog hom tshuaj nplaum iav, xaiv cov tshuaj nplaum pheej yig yog qhov tsis zam, tab sis kev siv cov tshuaj nplaum pheej yig tsis tsuas yog cuam tshuam rau qhov zoo thiab lub neej ua haujlwm ntawm qhov project, tab sis qhov tseem ceeb dua, nws yooj yim heev rau kev ua haujlwm dua, ncua lub sijhawm tsim kho, thiab txawm tias ua rau muaj kev raug mob. Txhawm rau kom yeej cov txiaj ntsig loj, cov tub luam tsis muaj kev ntseeg siab tuaj yeem ua si dag ntxias ntawm kev ntim khoom, siv cov fwj ntim khoom tuab kom txo qhov hnyav ntawm cov tshuaj nplaum, thiab hloov cov tshuaj nplaum hom nrog cov tshuaj nplaum qis dua. Cov txiaj ntsig loj uas lawv tau txais yog raws li tus nqi. Cov tshuaj nplaum iav qib qis uas muaj tib qhov hnyav tuaj yeem pheej yig dua li cov tshuaj nplaum iav hom 3 zaug, tab sis qhov viscosity thiab kev nruj ntawm cov tshuaj nplaum iav hom yog 3-20 npaug muaj zog dua li cov tshuaj nplaum iav qib qis, thiab lub neej ua haujlwm yog 10-50 npaug ntev dua. Yog li ntawd, cov chav haujlwm engineering yuav tsum tsis txhob txuag teeb meem, thiab tsuas yog los ntawm kev mus yuav khoom ib puag ncig lawv thiaj li ua kom qhov zoo ntawm qhov project; cov neeg siv khoom yuav tsum tsis txhob ntshaw nyiaj pheej yig, yog li ntawd kom tsis txhob cuam tshuam rau lub neej ntawm kev kho kom zoo nkauj sab hauv.

3. Yog tias koj tsis paub txog kev ua haujlwm ntawm cov iav sealant, tsis txhob siv nws dig muag.

Muaj ntau hom tshuaj nplaum iav hauv khw, suav nrog cov tshuaj nplaum iav acid, cov tshuaj nplaum uas tsis yooj yim rau huab cua, cov tshuaj nplaum silicic acid uas tsis yooj yim rau cov qauv, cov tshuaj nplaum pob zeb silicone, cov tshuaj nplaum tiv thaiv pwm tsis yooj yim, cov tshuaj nplaum iav khoob, cov tshuaj nplaum tshwj xeeb rau cov vaj huam sib luag txhuas-yas, cov tshuaj nplaum tshwj xeeb rau cov thoob dej yug ntses, cov tshuaj nplaum tshwj xeeb rau cov iav loj, cov tshuaj nplaum tshwj xeeb rau chav dej tiv thaiv pwm, cov tshuaj nplaum acid, thiab lwm yam. Cov neeg siv tsis nkag siab tag nrho txog cov yam ntxwv ntawm kev faib tawm, kev siv tau, kev txwv tsis pub siv thiab cov txheej txheem tsim cov tshuaj nplaum iav, thiab feem ntau ntawm lawv yeej tsis tau kov nws. Qee lub chaw lossis cov neeg siv khoom suav tias cov tshuaj nplaum iav yog "cov tshuaj nplaum thoob ntiaj teb". Tom qab ib xyoos, lawv pom tias qhov chaw uas siv cov tshuaj nplaum iav tau poob lossis hloov xim, yog li lawv tshawb xyuas seb cov tshuaj nplaum iav siv tau li cas. Nws hloov tawm tias cov ntaub ntawv tsim kho sib txawv yuav tsum xaiv cov tshuaj nplaum iav sib txawv. Yog li ntawd, tsis txhob siv cov tshuaj nplaum iav tsis paub qhov twg yog ib qho ntawm cov xwm txheej rau kev xaiv cov khoom tsim nyog.

4.Ua tib zoo saib hnub tsim khoom

Qhov kev ua tau zoo ntawm txhua yam ntawm cov tshuaj nplaum iav uas tas sij hawm lawm raug txo qis heev.

5. Sim ua los ntawm tes.

Tshem tawm qhov seem ntawm cov tshuaj nplaum iav uas ntws los ntawm ntug ntawm lub hau roj hmab, nias thiab rub nws maj mam nrog koj txhais tes. Yog tias nws puv nrog elasticity thiab mos, qhov zoo yog qhov zoo. Yog tias nws nyuaj me ntsis thiab brittle, qhov zoo ntawm cov tshuaj nplaum tsis meej.

6. Tom qab kho tag nrho

①Saib ntawm qhov ci ntsa iab ntawm qhov chaw. Cov tshuaj nplaum iav uas tau kho tag nrho, qhov ci ntsa iab ntawm qhov chaw zoo dua thiab du dua, qhov zoo dua.

② Xyuas qhov chaw kom paub seb puas muaj qhov hws. Qhov hws qhia tias qhov tshuaj tiv thaiv tsis sib npaug, thiab tej zaum yuav muaj teeb meem nrog cov mis.

③ Xyuas seb qhov chaw puas muaj roj. Yog tias muaj roj xau, nws txhais tau tias yuav kom txo tus nqi, yuav tsum ntxiv roj dawb ntau dhau thiab qhov zoo tsis zoo.

④Xyuas seb puas muaj hmoov nyob rau saum npoo. Yog tias nws yog hmoov, muaj qee yam tsis raug nrog cov mis.

⑤ Saib seb daim iav lo rau qhov twg. Siv tes rhuav daim iav sealant ntawm lub substrate, yog tias nws yooj yim rhuav tawm, nws txhais tau tias daim iav lo tsis zoo txaus. Ntawm qhov tod tes, nws yog qib siab tshaj plaws.

⑥ Sim ua kom yooj ywm. Tshem ib feem ntawm cov tshuaj nplaum iav thiab rub nws nrog tes. Qhov ntev ntawm cov tshuaj nplaum iav zoo tuaj yeem ncav cuag ob mus rau peb zaug ntawm qhov qub. Tom qab tso tes, nws tuaj yeem rov qab mus rau qhov ntev qub. Qhov ntev ntawm qhov elasticity tau khaws cia, qhov zoo ntawm cov tshuaj nplaum zoo dua. Saib cov xim thaum rub mus txog qhov txwv, qhov hloov pauv xim me dua, qhov zoo dua.

⑦ Saib seb puas muaj tej yam tsis huv. Siv koj txhais tes los zawm lub sealant iav kom txog thaum nws tawg, thiab xyuas seb sab hauv puas sib npaug thiab mos. Qhov zoo sib npaug thiab mos npaum li cas, qhov zoo dua.

⑧ Saib seb puas tiv taus pwm. Yog nws tsis pwm ntev npaum li cas, qhov sealant yuav zoo dua.

⑨Saib seb nws puas hloov xim. Yog tias xim tsis hloov ntev ntev, qhov sealant yuav zoo dua.

⑩Kev ruaj khov zoo. Qhov no suav nrog ntau yam, suav nrog kev tsim cov qauv, cov khoom siv raw, cov khoom siv tsim khoom thiab kev ruaj khov ntawm cov kws tshaj lij tsim khoom. Cov tshuaj nplaum iav zoo yuav tsum zoo ib yam rau txhua pawg khoom.

7.

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