Cov khoom lag luam polyurethane feem ntau suav nrog cov khoom hauv qab no: ua npuas ncauj yas, elastomers, fiber ntau plastics, fibers, tawv khau resins, coatings, adhesives thiab sealants, ntawm cov uas ua npuas ncauj plastics account rau ntau tshaj plaws.

polyurethane foaming yas

Polyurethane ua npuas ncauj yog muab faib ua npuas ncauj thiab mos ua npuas ncauj 2 yam, muaj zoo elasticity, elongation, compressive zog thiab softness, thiab zoo tshuaj stability.Tsis tas li ntawd, polyurethane ua npuas ncauj kuj muaj kev ua haujlwm zoo, adhesion, rwb thaiv tsev thiab lwm yam khoom, belongs rau kev ua tau zoo ntawm cov khoom tsis zoo.

Kev tsim cov khoom siv polyurethane tau kis thoob plaws hauv North America.Nws tau tshaj tawm tias qhov nruab nrab txhua xyoo kev loj hlob ntawm North American polyurethane ua npuas ncauj lag luam yuav tsum ncav cuag li 6%.Kev loj hlob yuav tsum tsom mus rau thaj chaw thiab kev lag luam ntawm cov tshuaj tsuag polyurethane ua npuas ncauj, nrog rau kev siv tub rog mus txog xyoo 2020. Tsis tas li ntawd, polyurethane tseem yuav siv rau hauv kev lag luam kho mob kom tau raws sijhawm thiab kev kho mob ntawm qhov txhab.

polyurethane elastomer

Vim nws cov qauv nrog cov muag muag thiab tawv ob ntu ntu, polyurethane elastomers tuaj yeem muaj lub zog siab, zoo toughness, hnav tsis kam, roj kuj thiab lwm yam khoom zoo heev los ntawm kev tsim cov saw hlau molecular.Polyurethane, hu ua "cov roj hmab hnav-tiv taus", muaj cov roj hmab siab elasticity thiab rigidity ntawm cov yas.

Nyob rau hauv lub xyoo dhau los, vim qhov poob loj ntawm tus nqi ntawm cov roj crude, nyob rau hauv cov ntsiab lus ntawm lub ntiaj teb no kev lag luam kev nyuaj siab, kev loj hlob ntawm polyurethane elastomer lag luam nyob rau hauv peb lub teb chaws piv rau lub xyoo dhau los, kev loj hlob qeeb, kev tsis txaus ntawm cov khoom. thiab qhov kev thov sib piv tiag tiag ua rau tus nqi ntawm polyurethane elastomer tag nrho txoj kev nqis.Txawm li cas los xij, qhov tshwm sim no tsuas yog tshwm sim hauv cov khoom lag luam polyurethane.Cov ntsiab lus thev naus laus zis thiab qib siab ntawm kev tsim kho tshiab ntawm cov khoom siv elastomer xws li nano polyurethane elastomer cov ntaub ntawv kev lag luam kev cia siab, los yog ntau heev.
