Dab tsi yog polyurethane thiab nws qhov zoo yog dab tsi

Polyurethane yog ib qho polymer compound tsim los ntawm kev sib xyaw thiab ua kom muaj zog xws li isocyanate thiab polyol. Nws muaj qhov zoo hauv qab no:

1. Kev puas tsuaj thiab kev cuam tshuam: cov ntaub ntawv polyurethane muaj lub zog siab thiab ua haujlwm ntev, thiab tuaj yeem tiv taus siab thiab hnyav hnyav nrog kev ua haujlwm siab heev rau kev puas tsuaj thiab cuam tshuam.

2. Tshuaj tiv thaiv: Polyurethane muaj cov tshuaj lom neeg muaj zog thiab tuaj yeem tiv taus ntau cov kua qaub, muaj zog hauv paus thiab lwm yam tshuaj lom neeg.

3. Kev ua haujlwm zoo rwb thaiv tsev: polyurethane muaj kev rwb thaiv tsev zoo thiab tsim nyog rau kev tsim khoom siv hluav taws xob xws li cov hluav taws xob hluav taws xob.

4. Zoo elasticity thiab saj zawg zog: Polyurethane muaj elasticity thiab saj zawg zog thiab muaj peev xwm tsim ib tug heev elastic khoom qauv, uas yog haum rau lub chaw tsim tshuaj paus.

ntawm cov pob qij txha, gaskets thiab lwm yam ntaub ntawv.

5. Kev ua haujlwm yooj yim: cov ntaub ntawv polyurethane muaj cov txheej txheem zoo, suav nrog kev sib xyaw molding, txhaj tshuaj molding, extrusion molding thiab ntau lwm txoj kev.

Qhov no ua rau polyurethane haum rau kev tsim khoom ntawm ntau yam kev lag luam, xws li tsheb, rooj tog, khoom siv kho mob, thiab lwm yam.
