Polyurethane nplaum yog ib yam khoom uas muaj ntau yam zoo. Lub ntsiab yog nws versatility. Nws tuaj yeem siv rau kev sib txuas pob zeb, qhov chaw ua los ntawm iav, hlau, ntoo, ceramics, polyurethane thiab polystyrene, nrog rau ntau yam khoom siv. Qhov no yog vim lub siab adhesion ntawm no muaj pes tsawg leeg rau tag nrho cov hom ntawm cov ntaub ntawv. Polyurethane ua raws li kev khi ntawm no, uas yog qhov tseeb ntawm lub npe.

Kev sib txuas ntawm qhov chaw nrog nws lav tiv thaiv cov tshuaj, qhov kub thiab txias, ntau yam kev cuam tshuam ib puag ncig, kub thiab noo noo. Xws li kev sib txuas tuaj yeem ua haujlwm nyob rau hauv qhov dav dav ntawm qhov kub ntawm -60 txog +120 degrees Celsius. Tsis tas li ntawd, polyurethane nplaum muab kev sib txuas muaj zog, tiv taus cov xwm txheej zoo li no,zoo li pwm thiab kab mob ua rau cov kab mob. Cov cuab yeej foaming tso cai rau koj kom paub tseeb tias qhov chaw nruab nrab ntawm qhov chaw yuav tsum tau glued tag nrho nrog nws. Qhov tsis muaj cov kuab tshuaj thiab tsw qab ua kom muaj kev nyab xeeb siab tshaj plaws thaum lub sijhawm ua haujlwm.

Muaj ob lub ntsiab lus thiab ib qho khoom siv polyurethane nplaum. Qhov kev xaiv thib ob yog yooj yim siv thiab yooj yim dua rau kev ua haujlwm nrog. Nws muaj prepolymer ntawm isocyanates. Vim lub siab viscosity ntawm cov khoom, zoo heev pib tack yog guaranteed. Kev sib cuam tshuam ntawm isocyanates nrog atmospheric noo noo ua rau muaj tshuaj lom neeg cov tshuaj tiv thaiv. Nws qhov tshwm sim yog tsim cov ntawv cog lus hla-molecular, vim qhov kev sib txuas ua kom muaj zog li sai tau.

Ob-kos polyurethane nplaum muaj ib khub ntawm cov khoom uas, thaum unmixed, yog yus muaj los ntawm tsawg viscosity. Tsuas yog tom qab kev sib xyaw ua ke, isocyanate hardener thiab polyol sib xyaw ua ke, vim tias qhov ua haujlwm ntawm cov nplaum ua tiav. Nws yog ib qho tsim nyog yuav tsum sib xyaw cov khoom nrog ua tib zoo saib ntawm qee yam kev siv tshuab, uas yog, qhov xav tau proportions, ntev ntawm lub sijhawm, thiab kub. Nrog rau txoj hauv kev zoo rau cov txheej txheem, kev sib cuam tshuam ntawm cov khoom tshwm sim. Kev ua raws li txhua yam kev mob ua rau muaj qhov tseeb tias cov yam ntxwv ntawm lub zog ntawm kev sib txuas los ntawm polyurethane nplaum ua rau siab kawg.

Cov nplaum nplaum polyurethane tuaj yeem pab tau zoo thaum tso parquet flooring. Rau Lavxias teb sab kev khiav hauj lwm tej yam kev mob, nws yog pom zoo kom siv ob-tivthaiv formulations uas tsis muaj cov kuab tshuaj los yog dej. Xws li cov ntaub ntawv muaj peev xwm tiv taus yuav luag txhua qhov kev ua haujlwm, yog li nws yog ib qho tsim nyog los siv lawv rau nteg lub rooj tsavxwm lossis ib qho array. Polyurethane nplaum tuaj yeem siv rau yuav luag txhua hom substrate, tsis tas yuav tsum tau ua ntej priming. Tshem tawm qhov seem ntawm qhov system yog qhov yooj yim heev. Polyurethane nplaum guarantees siab shear zog.
