Kev ua haujlwm thiab cov yam ntxwv ntawm cov khoom siv polyurethane

Dab tsi yog polyurethane
Lub npe tag nrho ntawm polyurethane yog polyurethane, uas yog lub ntsiab lus dav dav rau macromolecular compounds uas muaj cov pawg carbamate rov ua dua hauv cov saw tseem ceeb. Polyurethane tuaj yeem muaj ether ester urea biuret urea pawg qhia los ntawm polyurethane hauv Suav teb. Nws yog tsim los ntawm kev sib ntxiv ntawm cov organic diisocyanates los yog polyisocyanates nrog dihydroxy los yog polyhydroxy compounds. Cov khoom siv polyurethane muaj ntau yam kev siv thiab tuaj yeem hloov cov roj hmab, yas, nylon, thiab lwm yam. Nws yog siv rau hauv tshav dav hlau, tsev so, cov khoom siv hauv tsev, tsheb factories, thee mines, cement factories, high-end apartments, villas, landscaping, colourstones. art, chaw ua si, thiab lwm yam.
Lub luag haujlwm ntawm polyurethane:
1. Polyurethane ua npuas ncauj cov ntaub ntawv: muab faib ua polyurethane ua npuas ncauj, semi rigid polyurethane ua npuas ncauj thiab mos polyurethane ua npuas ncauj ntaub ntawv. Rigid polyurethane ua npuas ncauj yog tsuas yog siv rau lub tsev thermal rwb thaiv tsev cov ntaub ntawv, thermal rwb thaiv tsev cov ntaub ntawv (thermal rwb thaiv tsev ntawm pipeline chaw, thiab lwm yam), cov khoom siv rau txhua hnub (cov ntaub ntawv txaj txaj, sofas, thiab lwm yam., thermal rwb thaiv tsev txheej ntawm tub yees, cua txias, thiab lwm yam, thiab cov ntaub ntawv tseem ceeb ntawm surfboards, thiab lwm yam), thiab cov cuab yeej thauj mus los (lub ncoo, qab nthab, thiab lwm yam ntawm tsheb, dav hlau, thiab tsheb ciav hlau)
2. Polyurethane waterproof khoom: Kev siv cov khoom siv polyurethane waterproof yog qhov yooj yim heev, thiab nws tuaj yeem muab sib xyaw thiab coated rau ntawm qhov chaw rau chav sov noo noo curing kom tau ib txheej waterproof uas tsis muaj pob qij txha, roj hmab elasticity, thiab kev ua tau zoo. Thiab nws yog ib qho yooj yim los kho tom qab kev puas tsuaj. Feem ntau siv los ua cov ntaub ntawv hauv pem teb, cov ntaub ntawv taug qab thiab teb cov ntaub ntawv, racetracks, cov ntaub ntawv chaw ua si hauv pem teb, insulated qhov rais thav ntawv, thiab lwm yam.
3. Polyurethane elastomer: Polyurethane elastomer muaj lub zog tensile zoo heev, tsim kua muag tsis kam, cuam tshuam tsis kam, hnav tsis kam, huab cua tsis kam, hydrolysis tsis kam, roj tsis kam, thiab lwm yam zoo. Feem ntau yog siv los ua cov ntaub ntawv txheej (xws li hoses, gaskets, log tsheb, rollers, gears, pipelines, thiab lwm yam), insulators, khau khau, thiab internship log tsheb.
4. Polyurethane txheej: Polyurethane txheej muaj zog adhesion, thiab txheej zaj duab xis muaj zoo heev hnav tsis kam, dej tsis kam, thiab tshuaj tiv thaiv. Feem ntau yog siv rau cov rooj tog zaum, cov ntaub ntawv hauv tsev, thiab cov ntawv luam ntawv inks.
5. Polyurethane nplaum: Qhov kev ua tau zoo ntawm cov khoom siv kho tau tuaj yeem hloov kho los ntawm kev kho qhov sib piv ntawm isocyanates thiab polyols, ua tiav cov adhesion siab rau cov substrate, dej tsis kam, roj tsis kam, thiab tshuaj lom neeg. Polyurethane adhesives feem ntau yog siv hauv kev lag luam xws li ntim khoom, kev tsim kho, ntoo, tsheb, thiab khau.
6. Cov ntaub ntawv biomedical: Polyurethane muaj biocompatibility zoo heev thiab maj mam siv los ua cov khoom siv biomedical, uas tuaj yeem siv rau hauv kev tsim khoom ntawm lub plawv dhia pacemakers, cov hlab ntsha, cov pob txha, cov hlab ntsha, cov hlab ntsha, lub raum, thiab lwm yam. .
