Cov tshuaj nplaum iav
Cov tshuaj nplaum iav yog ib yam khoom siv los sib txuas thiab kaw ntau hom iav nrog lwm cov ntaub ntawv tseem ceeb. Nws feem ntau muab faib ua ob pawg: silicone sealant thiab polyurethane sealant (PU). Silicone sealant muab faib ua acid sealant, neutral sealant, structural sealant, thiab lwm yam. Polyurethane sealant muab faib ua adhesive sealant thiab sealant.
Cov ntawv thov tshwj xeeb ntawm cov iav sealant
1.Haum rau kev kaw cov ntaub thaiv huab cua ntawm ntau yam phab ntsa ntaub thaiv, tshwj xeeb tshaj yog pom zoo rau kev kaw cov ntaub thaiv iav, cov phab ntsa ntaub thaiv vaj huam sib luag txhuas-yas, thiab pob zeb dai qhuav.
2. Kev sib khi ntawm cov hlau, iav, txhuas, vuas ceramic, iav organic thiab iav coated.
3. Siv rau kev sib khi cov pob zeb ua vaj tse, cement, masonry, pob zeb, marble, hlau, ntoo, txhuas anodized thiab txhuas pleev xim. Feem ntau tsis tas yuav siv cov tshuaj primer.
4. Nws muaj kev tiv thaiv huab cua zoo heev xws li kev tiv thaiv ozone thiab kev tiv thaiv ultraviolet, thiab muaj lub neej ua haujlwm ntev.
Kev taw qhia txog sealant
Cov tshuaj nplaum yog hais txog cov khoom siv sib khi uas hloov pauv raws li qhov zoo li ntawm qhov chaw sib khi, tsis yooj yim ntws, thiab muaj qee lub zog nplaum. Nws feem ntau yog ua los ntawm cov khoom siv qhuav lossis tsis qhuav xws li asphalt, cov roj hmab ntuj lossis cov roj hmab hluavtaws, roj hmab ntuj lossis roj hmab hluavtaws, thiab tom qab ntawd ntxiv cov khoom siv inert, ua raws li cov yas, cov kuab tshuaj, cov neeg sawv cev kho, cov khoom ua kom nrawm, thiab lwm yam. Tos kom tsim khoom. Cov tshuaj nplaum yog qhov sib txawv los ntawm kev ua tau zoo. Lawv tsuas yog ua haujlwm yog kaw. Cov tshuaj nplaum uas tiv taus huab cua, cov tshuaj nplaum silicone, thiab cov tshuaj nplaum polyurethane txhua tus muaj cov haujlwm sib khi, tab sis lawv kuj muaj lwm yam haujlwm tseem ceeb heev, xws li lub zog sib txuas siab thiab tiv taus huab cua zoo.
Cov ntawv thov tshwj xeeb ntawm cov sealant
1. Raws li kev faib tawm, nws muaj peev xwm muab faib ua cov khoom siv foob rau lub tsev, cov khoom siv foob rau lub tsheb, cov khoom siv rwb thaiv tsev, cov khoom siv ntim khoom, cov khoom siv foob rau kev khawb av thiab lwm hom.
2. Raws li kev faib tawm tom qab kev tsim kho, nws tuaj yeem muab faib ua cov khoom siv kho thiab cov khoom siv semi-cured. Cov khoom siv kho tuaj yeem muab faib ua cov khoom siv khov kho thiab cov khoom siv yooj ywm. Cov khoom siv khov kho yog cov khoom khov uas tsim tom qab vulcanization lossis solidification. Nws muaj me ntsis elasticity, tsis tuaj yeem khoov, thiab feem ntau qhov sib koom ua ke tsis tuaj yeem txav mus los; cov khoom siv yooj ywm yog elastic thiab mos tom qab vulcanization. Cov khoom siv tsis kho yog cov khoom siv mos-curing uas khaws nws cov tackifier tsis-qhuav thiab txuas ntxiv mus rau qhov chaw tom qab thov.
Cov tshuaj nplaum rau cov qauv
Cov tshuaj nplaum uas ua los ntawm cov khoom siv no muaj zog heev (lub zog nias > 65MPa, lub zog sib txuas ntawm hlau thiab hlau zoo > 30MPa, lub zog txiav > 18MPa), tuaj yeem tiv taus cov khoom hnyav, tiv taus kev laus, kev qaug zog, thiab kev xeb, thiab muaj kev ua tau zoo hauv nws lub neej xav tau. Cov nplaum ruaj khov uas haum rau kev sib txuas cov khoom siv uas tuaj yeem tiv taus lub zog muaj zog.
1. Feem ntau yog siv rau cov khoom siv sib txuas ua ke lossis tsis yog cov qauv ntawm cov iav ntaub thaiv phab ntsa hlau thiab iav.
2. Lub iav tuaj yeem txuas ncaj qha rau ntawm qhov chaw ntawm cov khoom hlau los tsim ib qho khoom sib dhos kom ua tau raws li qhov yuav tsum tau tsim ntawm cov thav duab zais tag nrho lossis cov ntaub thaiv phab ntsa semi-zais.
3. Kev sib txuas thiab kaw cov iav rwb thaiv tsev.
4. Haum rau kev sib txuas, caulking thiab sealing ntawm cov pob zeb porous, laminated iav, insulating iav, daim iav iav, coated iav, zinc, tooj liab, hlau thiab lwm yam ntaub ntawv.
