Qhov sib txawv ntawm dej raws polyurethane thiab roj raws polyurethane
Dej-raws polyurethane dej txheej yog ib puag ncig tus phooj ywg high-molecular polymer elastic waterproof khoom nrog zoo adhesion thiab impermabeability. Nws muaj cov nplaum zoo rau txoj cai xis mas raws li cov kev ua kom zoo li pob zeb thiab pob zeb thiab hlau. Cov khoom lag luam muaj cov tshuaj ruaj khov thiab tuaj yeem tiv taus ntev ntev rau hnub ci. Nws muaj cov yam ntxwv ntawm elasticity thiab elongation loj.
Khoom Muag Khoom Zoo Ntaw
1. Pom: Cov khoom yuav tsum muaj kev ywj pheej los ntawm cov lumps tom qab nplawm thiab nyob hauv lub xeev tsis zoo.
2. Nws muaj lub zog siab tensile, siab elongation, zoo elongation, kev ua tau zoo nyob rau hauv siab thiab qis hloov mus rau qhov kev cog lus, tawg, thiab deformation ntawm substrate.
3. Nws adhesion yog qhov zoo, thiab tsis muaj kev kho mob primer rau ntau yam uas ua tau raws li qhov yuav tsum tau ua.
4. Tus txheej dries thiab ua zaj duab xis tom qab uas nws yog dej-resistant, corrosion-resistant, thiab qaug zog-resistant.
5. Nws txoj kev ua tau zoo ib puag ncig yog qhov zoo, vim tias nws tsis muaj benzene lossis thee tar tej, thiab tsis tas yuav muaj cov kuab tshuaj ntxiv thaum lub sijhawm kev tsim kho.
6. Nws yog ib qho ib-tiv thaiv, cov khoom txias-thov cov khoom uas yooj yim siv thiab siv.
Daim ntawv thov tau txais cov khoom lag luam
1. Haum rau cov chav nyob hauv av, chaw nres tsheb hauv av ntau, qhib-txiav subway thiab tunnels
2. Chav ua noj, chav ua noj, chav dej, chav tsev slabs, balconies, ru tsev uas tsis yog ru tsev.
3. Ntsug waterproofing thiab waterproofing thiab waterproofing ntawm cov ces kaum, pob qij txha thiab lwm yam paub zoo, nrog rau kev sib khi ntawm cov pob qij txha waterproofing.
4. Dej ntsw rau cov pas dej da dej, chaw ua luam dej, tso tsheb hlau luam, thiab irrigation raws.
5. Dej tsis pub rau chaw nres tsheb ntau thiab square ru tsev.
Roj-based polyurethane dej txheej yog lub siab molecular waterproof txheej uas muaj kev tawm tsam ntau thiab solidifies ntawm saum npoo. Nws yog ua los ntawm Isocyanates thiab Polyols ua cov khoom siv tseem ceeb, nrog ntau cov txheej txheem ua haujlwm ntawm cov txheej txheem tshwj xeeb uas muaj lub cev qhuav dej tsis muaj zog thiab cov tshuaj tiv thaiv. Thaum siv, nws tau thov rau waterproof substrate, thiab nyuaj, yoog raws pawg ntawm polyurethane Prepolymer thiab noo noo nyob saum huab cua.
Khoom Muag Khoom Zoo Ntaw
1. Pom: Cov khoom yog cov khoom siv viscous uas tsis muaj gel thiab qog.
2. Tib txoj kev, npaj siv rau ntawm qhov chaw, kev tsim kho txias, yooj yim siv, thiab qhov yuav tsum tau ua rau cov neeg noo noo ntawm cov txheej av tsis nruj.
3. Cov nplaum muaj zog: zoo adhesion rau qhob, c tov khoom, ntoo, thiab lwm yam, thiab lwm yam, tawg thiab deformation ntawm substrate.
4. Zaj duab xis yam tsis muaj nqaws: tsis xav tau thov primer ntawm ntau hom substrates uas ua tau raws li qhov yuav tsum tau ua.
5. Lub zog tensile ntawm cov yeeb yaj kiab, loj elongation tus nqi, zoo elongation, zoo adjectability rau shrinkage thiab deformation ntawm substrate.
6. Tshuaj lom neeg Kuj, tsis tshua muaj cua kub, tsis tshua muaj kev tiv thaiv, pwm tiv taus, tsis muaj dej tsis zoo. Daim ntawv thov tau txais cov khoom lag luam
Roj-Raws Polyurethane Dej Txheej Yuav siv tau rau kev lim dej ua haujlwm tshiab thiab cov chav dej, ua luam dej, cov chav dej, thiab lwm yam.
Qhov sib txawv ntawm cov roj-raws polyurethane thiab dej-raws polyurethane:
Roj-raws Polyurethane muaj cov ntsiab lus hnyav dua li cov txheej txheem dej thiab cov roj hmab, thiab ntau yam kev tshem tawm dej num tshwj xeeb, xws li dej tshem tawm dej thiab polymerization. Nws muaj qib kev ua qias tuaj ntau dua, piv rau cov dej polyurethane, uas yog cov khoom ntsuab thiab ib puag ncig ib puag ncig yam tsis muaj pa. Nws yog qhov haum rau kev siv nyob sab hauv, xws li chav ua noj thiab chav dej.
