Dab tsi yog Cov Khoom Tseem Ceeb ntawm Cov Khoom Siv Polyurethane?
Polyurethane (tseem hu ua PUR lossis PU) yog lub npe nrov rau nws lub zog tshwj xeeb thiab ua haujlwm ntev, ua tsaug rau nws cov qauv polymer tshwj xeeb uas ua los ntawm kev hloov cov mos thiab tawv copolymer ntu. Qhov kev sib cais nyob rau hauv cov qauv no ua rau nws muaj peev xwm ua tau ntau yam, ua rau nws tsim tau rau hauv cov ntaub ntawv sib txawv ntawm cov tawv nqaij, hardness, thiab ntom.
1. Cov khoom siv tau yooj yim thiab lub zog: Polyurethane tshwj xeeb sib xyaw ua ke ntawm cov roj hmab yooj yim nrog lub zog ntawm cov yas tawv, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau ob qho tib si yooj thiab toughness.
2. Durability thiab Elasticity: Cov khoom siv tau zoo heev thiab muaj zog, muaj peev xwm tiv taus kev siv ntau zaus thiab raug rau qhov chaw hnyav yam tsis muaj kev puas tsuaj lossis poob nws cov khoom ua haujlwm.
3. Impact and Wear Resistance: Polyurethane excels nyob rau hauv ob qho tib si kev cuam tshuam thiab hnav tsis kam, ua kom lub neej ntev kev pab cuam thiab kev ntseeg tau txawm nyob rau hauv kev nyuaj thiab abrasive tej yam kev mob.
Kev cai formulations ntawm polyurethane tso cai rau kev ua tau zoo tus yam ntxwv uas yuav ua tau zoo-tuned kom tau raws li tej yam kev thov. Tsis tas li ntawd, nws cov tshuaj tiv thaiv thiab kev kub siab ua rau nws yog cov khoom siv zoo tagnrho rau ntau qhov kev lag luam uas xav tau cov kev daws teeb meem siab. Zuag qhia tag nrho, polyurethane cov khoom sib txawv ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev lag luam uas xav tau cov ntaub ntawv uas xa ob lub zog thiab hloov tau.
BEIQIAO polyurethane raw khoomyog cov chaw tsim khoom hauv Suav teb rau polyurethane raw khoom, tuaj yeem muab cov khoom sib xyaw polyol, polyester polyol, polyurethane prepolymer, TPU thiab lwm yam.
