Lawv txhua tus muaj zog adhesion, cov khoom siv tshuaj lom neeg ntawm cov khoom yog ruaj khov, lawv tuaj yeem tiv taus lub hnub ci ntev, lawv muaj lub zog siab, loj elongation, zoo elasticity thiab zoo waterproof nyhuv.
Nws tuaj yeem siv rau ntawm qhov chaw ntub dej, thiab tuaj yeem kho tau rau hauv cov khoom tsis muaj tshuaj lom, tsis muaj ntxhiab, muaj zog elastic waterproof zaj duab xis tom qab txheej.
Nws yog ib tiam tshiab ntawm ib puag ncig tus phooj ywg waterproof khoom.
Qhov zoo ntawm cov dej-raws li polyurethane txheej
① Kev hnav zoo heev.
② Cov tshuaj lom neeg thiab roj ua haujlwm zoo heev.
③ Muaj zog adhesion.
④ Tsawg kub kho kev ua haujlwm.
⑤ Kev ua haujlwm zoo nkauj zoo nkauj.
⑥ Kev ua tau zoo sib txawv thiab kho tau.
Los ntawm kev txhim kho cov qauv, txheej zaj duab xis ntawm polyurethane tuaj yeem ua rau hauv cov zaj duab xis txheej nrog cov tawv tawv, thiab tuaj yeem ua rau hauv cov txheej txheem elastic nrog kev yooj yim heev, uas zoo heev txhim kho cov ntawv thov ntawm polyurethane txheej.
⑦ Kub kub thiab kub tsis kam.
⑧Cov zaj duab xis txheej yog non-toxic tom qab kho.
⑨ Ib puag ncig tus phooj ywg qis VOC txheej.
Disadvantages ntawm dej-raws li polyurethane txheej
① Lub crosslinking ceev yog tsawg, thiab tag nrho cov kev ua tau zoo ntawm waterborne polyurethane txheej tseem muaj qee qhov sib txawv piv nrog cov kuab tshuaj raws li polyurethane (PU).
② Kev ua haujlwm tsis zoo los tiv thaiv corrosion.
③ Tsawg hydrolyzable me ntsis.
Kev siv:
1. Zuag qhia tag nrho waterproofing ntawm lub tsev ru tsev dav hlau, qhov chaw siab tshaj, sab hauv thiab sab nrauv phab ntsa, chav ua noj thiab da dej, pas dej da dej, gutters thiab lwm yam.
2. Hauv qab daus: pob zeb hauv pem teb, hauv pem teb beams, shear phab ntsa, tuav phab ntsa, thiab lwm yam.
3. Waterproofing tunnels, subway tej yaam num, ditches, of elevator shafts, sluices, thiab dej phwj kho tanks.
4. Txhim kho cov kev sib khi ntawm cov kav dej hauv phab ntsa, cov kav dej downpipes, nthuav cov pob qij txha, thiab cov pob qij txha.
5. Anti-corrosion rau saum npoo ntawm cov kav dej hlau, tsis muaj dej tsis zoo thiab tiv thaiv corrosion ntawm galvanized ntawv ru tsev.
