Sealant yog cov khoom siv sealing uas deforms rau hauv cov duab ntawm kev sib khi saum npoo, tsis yooj yim ntws, thiab muaj qee yam nplaum. Nws yog cov nplaum siv los sau cov khoob ntawm cov khoom los ua lub luag haujlwm sib khi. Nws muaj cov haujlwm ntawm kev tiv thaiv, qaug dej, anti--rwb thaiv tsev thiab rwb thaiv tsev kub.
Nws feem ntau yog raws li qhuav lossis tsis qhib lub hom phiaj viscous xws li asphalt, ntuj cob lossis hluav taws xob cob, roj hmab lossis hluavtaws roj hmab. Nws yog ua nrog cov inert filters xws li talc, av nplaum, carbon dub, thiab tom qab ntawd ntxiv cov tshuab nqus, cov sawv cev, cov neeg sawv cev kom nrawm, thiab lwm yam.
Ntawm kev muab xov huam
Sealant tuaj yeem muab faib ua cov xov xwm tshiab, ua kua Sealant Gasket thiab peb pawg ntawm kev sib khi PUTTY.
Raws li kev siv tshuaj lom neeg muaj pes tsawg leeg:Nws tuaj yeem muab faib ua cov hom roj hmab, cob hom roj, roj-roj thiab cov polymer ua las voos. Cov qauv kev faib tawm no tuaj yeem paub cov yam ntxwv ntawm cov ntaub ntawv polymer, infer lawv qhov kub tsis kam, sefting thiab kev yoog raws thiab yoog thiab yoog thiab hloov mus rau ntau yam xov xwm.
Roj Hmab Hom:Hom kev foob no yog raws li roj hmab. Cov roj hmab feem ntau yog cov roj hmab polysulfide, silicone roj hmab, polyurethane roj hmab, neoprete roj hmab thiab butyl roj hmab.
Resin Hom:Hom kev sib tw no yog ua raws cob. Feem ntau siv cov resins yog epoxy cob, unsaturated polyester cob, polyacrylic cob, polyvinyl chloride Resin, thiab lwm yam.
Roj-Raws Li:Hom kev foob no yog cov roj-raws. Cov roj siv feem ntau yog ntau cov roj cov roj xws li roj nqa, cov roj taum roj thiab roj roj xws li roj ntses.
Kev faib tawm raws li daim ntawv thov:Nws tuaj yeem faib ua cov hom siab kub, txias ua hom, hom siab thiab lwm yam.
Kev faib ua ke raws li cov khoom siv ua yeeb yam:Nws tuaj yeem muab faib ua cov nplaum nplaum qhuav, hom patable, tsis yog-qhuav nplaum hom viscoelastic.
Kev faib tawm los ntawm kev siv:Nws tuaj yeem muab faib ua cov khoom siv tshuab, cov tsheb sib foob, rwb thaiv tsev foob, ntim khoom siv tshuab, tsuas yog foob thiab lwm yam.
Raws li kev ua tau zoo tom qab kev tsim kho:Nws tuaj yeem faib ua ob hom: Kho sealant thiab semi-kho sealant. Ntawm lawv, kho sealant tuaj yeem faib ua kom nruj thiab hloov tau. Rigid Sealant yog cov khoom siv tom qab vulcanization lossis solidification, thiab tsis tshua muaj elasticity, tsis tuaj yeem khoov, thiab feem ntau yog cov nqaws tsis tau txav mus; Saj zawg zog sealants yog elastic thiab muag tom qab vulcanization. Qhov tsis yog-kho sealant yog qhov muag muag muag muag uas tseem tswj kev sib txuas tsis tau tom qab kev tsim kho thiab tsis tu ncua migrates rau saum npoo.
