Qhov sib txawv tseem ceeb ntawm polysulfide thiab polyurethane sealants yog tias polysulfide sealants yog qhov zoo tshaj plaws rau cov pob qij txha uas tiv taus ntev rau hauv cov kua dej, hos polyurethane sealants yog qhov zoo tshaj plaws rau cov pob qij txha-rau-lawv.
Polysulfide sealant yog hom sealant tsim rau cov pob qij txha uas yuav tsum tau tiv thaiv kom ntev rau hauv cov kua. Polyurethane sealant yog ib hom sealant uas muaj ib qho khoom siv elastomeric sealant uas zoo li qhuav ntawm cov av noo thiab hauv chav tsev kub.
Polysulfide Sealant yog dab tsi?
Polysulfide sealant yog hom sealant tsim rau cov pob qij txha uas yuav tsum tau tiv thaiv kom ntev rau hauv dej. Feem ntau, hom sealant no yog siv rau cov pas dej da dej, cov qhov dej, cov yees txias, roj, thiab cov chaw khaws tshuaj, kev kho dej khib nyiab, thiab cov nroj tsuag petrochemical.
Polysulfide sealant muab lub zog ruaj khov, elastomeric, huab cua-nruj foob rau cov pob qij txha hauv kev lag luam thiab kev lag luam tseem ceeb. Nws muaj txiaj ntsig tshwj xeeb thaum raug rau cov kuab tshuaj. Ob hom polysulfide sealant uas muaj thiab muag muag yog Pecora Synthacalk GC2+ thiab TAMMSFLEX SL.
Feem ntau, polysulfide sealants kho ntawm qhov kub thiab txias los ntawm kev tsim cov tawv elastomeric foob uas nyiam ua raws li kev ua siab ntev rau masonry, hlau, thiab ntoo. Tsis tas li ntawd, hom sealant no muaj peev xwm tiv taus kev nthuav dav thiab kev cog lus thiab nyob twj ywm los ntawm kev hloov pauv txhua hnub thiab lub caij nyoog ntawm qhov kub thiab txias. Ntxiv mus, polysulfide sealants muaj cov tshuaj zoo heev, hnyav, thiab dej tsis kam nrog rau kev sib koom ua ke mus txog qhov sib txawv ntawm 25%.
Qhov tseem ceeb ntawm Polysulfide Sealant
- Muaj peev xwm siv lossis sib koom ua ke ntawm cov khoom zoo sib xws thiab tsis sib xws
- Resistant rau txaws thiab nchuav nrog dav hlau roj
- Zoo rau cov pob qij txha dynamic uas raug tshuaj lom neeg
- Ntau qhov kev pabcuam kub
YPolyurethane Sealant yog dab tsi?
Polyurethane sealant yog hom sealant uas muaj ib qho khoom siv elastomeric sealant uas zoo li qhuav ntawm cov av noo thiab hauv chav tsev kub. Peb tuaj yeem siv polyurethane sealant rau sealing thiab gluing. Hom sealant no tau siv dav vim nws muaj cov khoom zoo elastic, thiab nws lub zog ntawm qhov sib txawv yog siab. Tsis tas li ntawd, polyurethane sealant muaj kev tiv thaiv zoo rau kev cuam tshuam thiab kev co. Nws kuj muaj lub zog txhua yam zoo piv rau silicone.
Polyurethane sealants yog cov organic. Yog li ntawd, lawv qhia tsis tshua muaj zog piv rau qee qhov zoo silicone sealants. Piv txwv li, lub txee lub neej ntawm cov khoom no yog li ntawm 5-10 xyoo, nrog rau ntau yam teebmeem.
Polyurethane sealants muaj txiaj ntsig zoo hauv cov ntawv thov kev lag luam, cov cuab yeej ua si, khoom siv tes ua, thiab lwm yam. Nws yog qhov tseem ceeb rau kev sib khi thiab cov qauv sib koom ua ke thiab tsim nyog rau qhov chaw uas muaj dej noo. Ntxiv mus, cov sealants no muaj cov khoom zoo heev, uas qhia tau hais tias muaj kev cuam tshuam zoo rau kev ua haujlwm ntev thiab kev ua haujlwm ntawm cov ntaub ntawv, thiab nws muaj txiaj ntsig zoo hauv qhov chaw muaj kev vibrations.
Qhov tseem ceeb ntawm Polyurethane Sealants
- siab adhesion rau ntau qhov chaw
- Resistance ntawm noo noo thiab lwm yam huab cua
- Resistance rau corrosive agents
- siab yoog tau
- Resistance to tshav ntuj
Qhov txawv ntawm Polysulfide thiab Polyurethane Sealant yog dab tsi?
Qhov sib txawv tseem ceeb ntawm polysulfide thiab polyurethane sealants yog tias polysulfide sealants yog qhov zoo tshaj plaws rau cov pob qij txha uas yuav tsum tau ua kom ntev rau hauv cov kua dej, hos polyurethane sealants yog qhov zoo tshaj plaws rau kev sib koom ua ke.
Cov hauv qab no qhia txog qhov sib txawv ntawm polysulfide thiab polyurethane sealants nyob rau hauv daim ntawv tabular rau ib sab sib piv.
Summary – Polysulfide vs Polyurethane Sealant
Polysulfide sealant yog hom sealant tsim rau cov pob qij txha uas yuav tsum tau tiv thaiv kom ntev rau hauv dej. Polyurethane sealant yog ib hom sealant uas muaj ib qho khoom siv elastomeric sealant uas zoo li qhuav ntawm cov av noo thiab hauv chav tsev kub. Qhov sib txawv tseem ceeb ntawm polysulfide thiab polyurethane sealants yog tias polysulfide sealants yog qhov zoo tshaj plaws rau cov pob qij txha uas yuav tsum tau ua kom lub sijhawm ntev rau hauv cov kua, hos polyurethane sealants yog qhov zoo tshaj plaws rau kev sib koom ua ke.
