Tag nrho cov no yog cuam tshuam nrog cov sealant qhov rooj thiab qhov rais!
Cov tshuaj nplaum qhov rooj thiab qhov rai feem ntau yog siv los kaw qhov rooj thiab qhov rai thiab iav, thiab kaw cov thav qhov rai thiab cov nplaum phab ntsa. Thaum muaj teeb meem nrog cov tshuaj nplaum qhov rooj thiab qhov rai, cov khoom siv rwb thaiv tsev, rwb thaiv cua sov, rwb thaiv suab, tiv thaiv dej thiab lwm yam haujlwm ntawm qhov rooj thiab qhov rai yuav ploj mus, thiab yuav muaj ntau yam xwm txheej teev saum toj no tshwm sim.
Thaum nws los txog rau cov tshuaj nplaum qhov rooj thiab qhov rai, ntau tus neeg xav txog: Dab tsi? Puas yog cov tshuaj nplaum iav? Yog lawm, nws yog cov tshuaj nplaum iav uas tshwm sim ntau zaus hauv peb lub qhov ncauj. Tab sis nws tsis yog cov tshuaj nplaum iav xwb.
Lub Sijhawm Tshawb Fawb Nrov
Q: Vim li cas nws thiaj hu ua iav sealant?
A: Vim tias cov silicone sealant tsim nyob rau theem thaum ntxov yog acidic thiab tsuas yog siv tau los ntaus iav, yog li txhua tus hu nws ua iav sealant los ntawm kev lig kev cai. Cov neeg siv khoom ib txwm paub me ntsis txog kua nplaum, yog li txhua tus pib hu nws ua iav sealant.
Q: Vim li cas nws tsis yog tsuas yog cov sealant iav xwb?
A: Vim tias tam sim no nrog kev txhim kho sai ntawm kev lag luam roj hmab silicone, cov sealants tsis yog tsuas yog acidic sealants, tab sis kuj tseem muaj cov khoom siv tshiab ntawm cov sealants silicone nruab nrab tau tshwm sim. Peb siv nws rau ntawm qhov rooj thiab qhov rai, thiab nws hu ua silicone qhov rooj thiab qhov rai kua nplaum.
Cov tshuaj nplaum iav uas muaj kua qaub feem ntau yog siv rau kev tiv thaiv dej thiab kev kaw. Nws qhov tsis zoo yog tias nws muaj qee qib ntawm kev xeb, yog li cov ntaub ntawv uas siv tau tsawg. Tsis tas li ntawd, lub neej dav dav yog 2 txog 3 xyoos, thiab nws yooj yim ua rau tawg tom qab ntawd; cov tshuaj nplaum iav nruab nrab muaj ntau yam kev siv, tsis xeb, thiab ruaj khov. Nws qhov tsis zoo yog tias nws kho qeeb me ntsis. Kev xaiv cov tshuaj nplaum tshwj xeeb yuav tsum tau txiav txim siab raws li cov xwm txheej tiag tiag.
Q: Cov tshuaj sealant rau qhov rooj thiab qhov rai puas tiv taus huab cua?
A: Cov hom sealant siv rau ntawm qhov rooj thiab qhov rai suav nrog: silicone sealant, polyurethane sealant, dej-raws li sealant thiab silane-modified polyether sealant, ntawm cov silicone sealant yog qhov nyiam. Silicone sealant muaj qhov zoo tshaj plaws tiv taus huab cua, thiab nws cov saw hlau tshuaj lom neeg lub zog tseem ceeb siab dua lub zog ntawm 300nm ultraviolet lub teeb, yog vim li cas silicone sealant tuaj yeem tswj tau kev ua tau zoo hauv qab lub teeb ultraviolet rau lub sijhawm ntev.
Piv txwv li, siway 666 yog ib qho khoom siv silicone uas tsis ua rau ib puag ncig puas tsuaj. Ua ntej tshaj plaws, nws yog ib qho khoom siv silicone uas tsis ua rau ib puag ncig puas tsuaj, yog li nws txoj kev tiv thaiv huab cua zoo heev. Yog li ntawd, txawm tias lub npe puas yog cov khoom siv tiv thaiv huab cua, qhov kev tiv thaiv huab cua ntawm silicone sealant tsis tuaj yeem raug nug.
Yuav ua li cas xaiv cov tshuaj sealant rau qhov rooj thiab qhov rai
Cov tshuaj sealant tsuas yog suav txog 1 ~ 3% ntawm tag nrho cov nqi ntawm cov qhov rooj thiab qhov rai txuag hluav taws xob, tab sis nws qhov zoo cuam tshuam ncaj qha rau qhov zoo thiab kev txuag hluav taws xob ntawm tag nrho qhov project, thiab kuj cuam tshuam ncaj qha rau peb txoj kev nyob. Cov neeg feem ntau them sai sai rau "cov khoom loj" xws li iav thiab cov profile, thiab tsis quav ntsej txog cov khoom me me ntawm sealant. Cov neeg me ntsis paub tias cov sealant qhov rooj thiab qhov rai yog cov khoom tseem ceeb. Kev poob hluav taws xob los ntawm kev ua tsis tiav ntawm qhov rooj thiab qhov rai sealing yog ntau dua li kev txuag hluav taws xob uas tuaj yeem ua tiav los ntawm kev xaiv cov iav thiab cov profile zoo dua. Kev tham txog kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig hauv lub tsev uas xau cua thiab nag zoo ib yam li kev hais lus khoob.
Kev kaw qhov rooj thiab qhov rai uas tiv taus huab cua thiab dej tsis nkag yog ib qho project uas muaj txheej txheem, ib yam li cov phab ntsa ntaub thaiv, suav nrog kev kaw ntawm cov thav duab qhov rai thiab iav, kev kaw ntawm cov phab ntsa sab nraud thiab cov thav duab qhov rooj thiab qhov rai, thiab lwm yam. Thaum lub caij ntuj sov, lub hnub ci muaj zog thiab huab cua hnyav xws li cua daj cua dub thiab nag xob nag cua feem ntau tshwm sim. Nws yog lub sijhawm muaj teeb meem ntawm qhov rooj thiab qhov rai ntau. Peb yuav tsum xyuam xim rau cov teeb meem twg thaum xaiv thiab siv cov tshuaj silicone sealant rau qhov rooj thiab qhov rai?
1. Xaiv cov khoom lag luam ib txwm uas ua tau raws li cov qauv hauv tebchaws
GB/T 8478-2020 "Qhov Rooj thiab Qhov Rai Aluminium Alloy" tau hais txog cov kev cai rau kev sib khi thiab cov ntaub ntawv sib txuas rau qhov rooj thiab qhov rai aluminium alloy. Tsis tas li ntawd, GB/T 14683-2017 "Silicone thiab Modified Silicone Building Sealant", JC/T 881-2017 "Sealant for Concrete Joints", JC/T 485-2007 "Elastic Sealant for Building Windows" thiab lwm cov qauv kuj tau teeb tsa cov cim qhia txog cov sealant rau qhov rooj thiab qhov rai hauv tsev.
2. Xaiv ib lub hom lag luam loj uas ntseeg tau
Kev lag luam kua nplaum rau qhov rooj thiab qhov rai muaj ntau yam sib xyaw, nrog rau cov hom lag luam ib txwm muaj thiab cov hom lag luam theej tawm hauv cov kwj deg tsis kawg, thiab kuj muaj cov khoom cuav. Xaiv lub hom lag luam loj ib txwm muaj nrog lub zog thev naus laus zis los ua kev tshawb fawb txog kev ua tau zoo ntawm cov khoom, tswj hwm cov khoom siv raw thiab cov txheej txheem tsim khoom nruj me ntsis, thiab cov khoom tsuas yog tuaj yeem xa tuaj tom qab ntau txheej kev tshuaj xyuas, yog li qhov zoo tau lees paub.
3. Ua tib zoo saib xyuas qhov kev ua tau zoo ntawm ib puag ncig ntawm cov khoom
Hais txog qhov volatility, VOC cov ntsiab lus, cov hlau hnyav, thiab lwm yam ntawm cov sealant, nws nyuaj rau cov neeg siv khoom pom cov lus qhia los ntawm cov khoom nrog lawv lub qhov muag liab qab. Nws raug pom zoo kom them sai sai rau cov kev cai tiv thaiv ib puag ncig ntawm cov chaw tsim khoom, xws li seb nws puas tau dhau ISO9001 kev tswj hwm zoo, ISO14001 kev tswj hwm ib puag ncig, ISO45001 kev noj qab haus huv thiab kev nyab xeeb hauv chaw ua haujlwm, thiab seb nws puas muaj daim ntawv pov thawj tiv thaiv ib puag ncig thib peb.
4. Kev tsim kho kom raug
Cov roj hmab silicone sealant raug cuam tshuam loj heev los ntawm ib puag ncig (kub thiab av noo). Feem ntau siv rau hauv ib puag ncig huv si nrog qhov kub ntawm 5 ~ 40 ℃ thiab av noo ntawm 40% ~ 80%. Yog li ntawd, nws tsis pom zoo kom siv cov kua nplaum rau hauv ib puag ncig dhau qhov ntau saum toj no.
Tsis tas li ntawd xwb, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov chaw huv thiab qhuav ntawm cov qhov rooj thiab qhov rai uas yuav tsum tau tsim. Thaum lub caij ntuj sov, qhov kub thiab txias thiab av noo siab, thiab yuav tsum tau them sai sai rau kev thov kua nplaum sai li sai tau (yog tias xav tau primer, thov kua nplaum sai li sai tau tom qab thov primer), thiab kev txiav yuav tsum tau ua tam sim ntawd tom qab ua tiav. Tom qab ntawd, nws yuav tsum tau kho rau ntau tshaj 12 teev nyob rau hauv cov xwm txheej zoo li qub thiab tsis muaj kev ntxhov siab raws li cov xwm txheej kho ntawm cov khoom sib txawv.
5. Khaws cia kom raug
Huab cua kub thiab av noo ntau yuav ua rau lub sijhawm khaws cia ntawm cov khoom luv dua thiab ua rau cov khoom puas ua ntej lub sijhawm. Yog li ntawd, nws raug pom zoo kom siv cov sealant sai li sai tau tom qab qhib thaum lub caij ntuj sov. Thaum lub caij ntuj sov, nws yog noo thiab los nag. Nws yuav tsum nco ntsoov tias cov sealant yuav tsum tau khaws cia rau hauv qhov chaw cua thiab txias nrog thaj chaw siab kom tiv thaiv cov sealant kom tsis txhob raug nag lossis dej los ntawm huab cua hnyav, uas yuav cuam tshuam rau lub sijhawm khaws cia ntawm cov khoom thiab ua rau muaj teeb meem kho hauv cov khoom ntim.
Muaj ntau tus neeg siv khoom tsis muaj kev ua haujlwm zoo ntawm cov qhov rooj thiab qhov rai hauv tsev, thiab thawj qhov kev xav yog hloov cov qhov rooj thiab qhov rai - tam sim no peb paub tias qhov no tsis tsim nyog. Ua ntej, ua tib zoo xyuas seb cov kua nplaum ntawm qhov rooj thiab qhov rai puas tau tawg, tawv, lossis muaj kev ua haujlwm tsis zoo. Yog tias qhov teeb meem nyob nrog cov sealant, ces koj tsuas yog yuav tsum hloov nws nrog cov sealant silicone zoo nrog kev lees paub zoo.
