Nyob rau hauv niaj hnub kev lag luam khoom siv hauv tsev, ntau thiab ntau polyurethane tuaj yeem pom hauv khw.Polyurethane yog cov khoom siv ntau yam, tab sis ntau tus neeg tsis nkag siab tias polyurethane yog dab tsi lossis nws ua li cas.Hauv kev teb rau qhov xwm txheej no, tus editor tau sau cov ntaub ntawv hauv qab no los muab kev tshawb fawb nrov rau koj.“

Polyurethane yog dab tsi?

Lub npe tag nrho ntawm polyurethane yog polyurethane, uas yog lub ntsiab lus dav dav rau macromolecular compounds uas muaj cov pawg urethane rov ua dua ntawm cov saw tseem ceeb.Polyurethane yog ib pawg ntawm cov urethane hauv kuv lub teb chaws, thiab nws tseem tuaj yeem muaj ether ester urea biuret urea pawg thawj pawg qhia txog polyurethane.Nws yog tsim los ntawm polyaddition ntawm organic diisocyanate los yog polyisocyanate thiab dihydroxyl los yog polyhydroxyl compound.Cov khoom siv polyurethane muaj ntau yam kev siv, nws tuaj yeem hloov cov roj hmab, yas, nylon, thiab lwm yam, siv 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:

Polyurethane tuaj yeem siv rau hauv kev tsim cov yas, roj hmab, fibers, nruj thiab yoog raws foams, adhesives thiab coatings, thiab lwm yam. Nws tuaj yeem siv rau ntau yam ntawm tib neeg lub neej thiab muaj ntau yam kev siv.

1. Polyurethane ua npuas ncauj: muab faib ua polyurethane ua npuas ncauj, semi-rigid polyurethane ua npuas ncauj thiab saj zawg zog polyurethane ua npuas ncauj.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 txhua hnub ( txaj, sofas, thiab lwm yam. pads, tub yees, cua txias, thiab lwm yam., rwb thaiv tsev txheej, thiab surfboards. , thiab lwm yam. core material. ), thiab txhais tau tias kev thauj mus los (cov khoom xws li cushions thiab qab nthab rau tsheb, dav hlau, thiab tsheb ciav hlau).

2. Polyurethane elastomer: Polyurethane elastomer muaj qhov zoo ntawm lub zog tensile zoo, lub zog tsim kua muag, kev cuam tshuam tsis kam, tsis kam tiv taus, huab cua tsis kam, hydrolysis tsis kam, roj tsis kam thiab lwm yam.Feem ntau yog siv rau cov ntaub ntawv txheej (xws li kev tiv thaiv hoses, ntxhua khaub ncaws, log tsheb, rollers, iav, kav dej, thiab lwm yam), insulators, khau khau, thiab cov log tsheb.

3. Polyurethane waterproof khoom: Polyurethane waterproof khoom yog yooj yim heev rau siv.Nws tuaj yeem muab sib xyaw thiab coated rau ntawm qhov chaw thiab kho nrog qhov kub thiab txias, thiab cov txheej txheem dej tsis muaj seams, roj hmab elasticity thiab kev ua haujlwm zoo tuaj yeem tau txais.Thiab yooj yim kho tom qab kev puas tsuaj.Feem ntau siv los ua cov ntaub ntawv paving, cov ntaub ntawv taug qab thiab teb cov ntaub ntawv, racetracks, cov khoom siv hauv av, cov ntaub ntawv thermal rwb thaiv tsev qhov rais, thiab lwm yam.

4. Polyurethane txheej: Polyurethane txheej muaj zog adhesion, thiab txheej zaj duab xis tau zoo heev hnav tsis kam, dej tsis kam thiab tshuaj lom neeg.Feem ntau yog siv rau rooj tog coatings, tsev cov ntaub ntawv coatings thiab industrial printing inks.

5. Polyurethane nplaum: Qhov kev ua tau zoo ntawm cov khoom kho tuaj yeem hloov kho los ntawm kev kho qhov piv ntawm isocyanate thiab polyol, kom nws tuaj yeem ua tiav siab adhesion rau substrate, zoo heev dej tsis kam, roj kuj thiab tshuaj tiv thaiv.Polyurethane adhesives yog siv rau hauv ntim, kev tsim kho, ntoo, tsheb, shoemaking thiab lwm yam lag luam.

6. Biomedical cov ntaub ntawv: Polyurethane muaj biocompatibility zoo heev, yog li nws maj mam siv los ua cov ntaub ntawv biomedical.Nws tuaj yeem siv rau hauv kev tsim cov khoom siv dag zog hauv lub plawv, cov hlab ntsha, cov pob txha, cov hlab ntsha, cov raum, cov khoom siv lim ntshav, thiab lwm yam.

Cov saum toj no yog qee cov ntaub ntawv hais txog dab tsi yog cov khoom siv polyurethane thiab lub luag haujlwm ntawm polyurethane uas tus editor tau muab tso ua ke rau koj.Polyurethane maj mam nce qhov chaw ruaj khov hauv cov khoom siv hauv tsev vim nws khawb tsis kam thiab lwm yam ntxwv.Netizens tuaj yeem yuav raws li lawv tus kheej xav tau kev txhim kho tsev.
