Polyurethane txheejyog cov khoom siv waterproof zoo heev thiab dav siv waterproof. Nws suav hais tias yog ib qho ntawm qhov siab - Kev ua yeeb yam waterpoof txheej, tshwj xeeb tshaj yog nyob rau hauv cov dej num uas xav tau siab heev, thiab daim ntawv thov ntawm cov chaw sib txawv.
Vim li cas Polyurethane muaj kev ua haujlwm zoo tshaj plaws waterproof?
1. Seamless nruam zaj duab xis
Polyurethane txheej tau thov hauv cov foos ua kua - los ntawm kev txhuam hniav, lossis txau rau hauv ib qho txuas ntxiv, ntom, seamless elastic membrane.
Daim ntawv no tau npog lub substrate no zoo li "Raincoat," tiv thaiv kev nkag mus.
2. Tshwj xeeb elasticity thiab elongation
Polyurethane Waterproof MiCBranes muaj elongation zoo heev (tshaj 300% lossis siab dua).
Thaum lub substrate (xws li pob zeb ua) nthuav dav, ntawv cog lus, lossis tawg vim qhov ntsuas kub lossis txias, cov khoom siv hluav taws xob tsis yeem, cov tshuaj lom ib txwm muaj dej ntws zoo li.
Txawm li cas los xij, txheej txheem polyurethane tuaj yeem ncab nrog kev txav ntawm cov nrib pleb tsis muaj tawg, yog li tswj kev ncaj ncees ntawm cov dej dej.
3. Cov nplaum muaj zog
Nws adheres zoo rau ntau yam substrates xws li pob zeb ua, hlau, ua rau nws resistant rau tev lossis delamination.
4. Tshuaj tiv thaiv thiab puas tsis kam
Polyurethane txheej tiv thaiv acids, alkalis, thiab ntsev rau qee yam.
Nws saum npoo yog tawv thiab hnav - tiv taus, ua rau nws haum rau cov chaw muaj ru tsev xws li ru tsev thiab balconies.
Cov Hom Polyurethane Waterproof Txheej
1. Ib {- sib xyaw polyurethane dej txheej
Composition: Prepolymer, siv ncaj qha los ntawm lub thawv; Kho kom zoo los ntawm nqus dej noo los ntawm huab cua.
Cov txiaj ntsig: Npaj siv, yooj yim thov, tsis tas yuav muaj kev sib xyaw lossis hnyav.
Qhov tsis zoo: Kev kho kom nrawm nyob ntawm seb muaj qhov kub thiab txias thiab huab cua sov thiab av noo; tob - txheej yuav kho tej zaum yuav qeeb.
Cov Kev Siv Cov Ntawv Zoo: Kev kho me me, tsis {{{}}} cov chaw nyob hauv kev sib xyaw.
2. Ob {{{{}} sib xyaw polyurethane Dej Txheej
Kev sib xyaw: muaj cov khoom sib xyaw ua ke (prepolymer) thiab cov prepolymer) thiab sib xyaw b (tus neeg sawv cev), uas yuav tsum tau sib xyaw rau hauv cov kev sib piv ua ntej siv.
Cov txiaj ntsig: Ntau ruaj khov ua tau zoo, kho tau lub sijhawm kho tau, thiab cov khoom siv zoo dua (lub zog thiab elasticity).
Qhov tsis zoo: Yuav tsum muaj qhov sib xyaw ua ke thiab meej stirring rau ntawm qhov chaw; Lauj kaub lub neej lub neej tom qab sib tov.
Cov ntawv thov raug: loj {- Cov phiaj xwm charnel, ntev- pas dej kawm, hauv qab,
Daim ntawv thov tseem ceeb
Lub ru tsev waterproofing: tshwj xeeb tshaj yog haum rau lub ru tsev tsis xwm yeem.
Hauv qab daus lim dej: zoo rau ntawm phab ntsa thiab plag tsev kom tiv thaiv cov dej hauv av siab.
Chav dej thiab chav ua noj ua noj: Xaiv eco - tus phooj ywg hom thiab ua kom muaj qhov cua zoo.
Pas dej da, tso tsheb hlau luam dej, thoob dej yug ntses: ua tau zoo nyob rau hauv ntev - lub sij hawm imipersion.
Txuas hniav, chaw nres tsheb lawj, thiab cov dej num hauv nroog.
Kev sib piv nrog lwm cov txheej txheej dej tsis muaj zog
vs. acrylic pleev xim:
Acrylics tseem yog elastic thiab ntau tus phooj ywg (dej {- raws li), tab sis lawv cov elasticity thiab durability yog feem ntau qis dua polyurethane.
Zoo dua rau kev sib tw ru tsev, tsis yog rau ntev - lub sij hawm lim dej raus dej.
JS JS POLYMER CAAS COASS COAs:
JS coatsings ua ke thiab rigidity, tuaj yeem thov rau ntub dej, thiab tsis yog {{{{{1} {1} tus phooj ywg.
Txawm li cas los xij, lawv elasticity yog qis dua polyurethane, yog li lawv feem ntau siv hauv tsev (piv txwv li, chav dej).
Vs. SBS / APP Hloov Bitumen Daim Duab:
Cov nyias nyias tau thov tab sis muaj cov ntsiab lus tsis muaj zog ntawm cov chaw sib txuas thiab cov chaw ua kom zoo rau cov dej - Thov polyurethane txheej.
