Polyurethane
Nws muaj ntau yam polyurethane. Polyurethanes yog tsev neeg muaj kab xev, lossis tshwj xeeb ntau, elastomeric polymers, uas suav nrog roj hmab, uas, txij li thawj zaug tsim tawm xyoo 1937, tau yoog kom tsim cov khoom lag luam dav dav. Cov khoom siv yog qhov tshwj xeeb ntau yam, ruaj khov, hloov tau, hloov tau, thiab resilient. Tsim los ntawm kev sib txuas ntawm poly-isocyanate thiab polyol, polyurethane tuav txhua yam khoom uas muab nws lub zog ntawm cov tawv yas thiab cov elasticity ntawm roj hmab.
Cov ntawv thov polyurethane yog ze li tsis muaj qhov kawg, thiab nws feem ntau siv hloov ntoo, hlau, pleev xim, lossis paj rwb rau ntau qhov chaw thiab qhov chaw rau cov neeg siv khoom thiab cov khoom lag luam. Ua npuas dej hauv cov txaj thiab rooj tog txaj txaj - rooj zaum, rooj zaum, rooj tog zaum rooj - yog ua los ntawm polyurethane, thiab yog li ua npuas mos muag pom hauv cov khoom ua si thiab hauv ncoo. Kev rwb thaiv tsev hauv cov phab ntsa thiab ru tsev, kua pleev xim rau xim thiab xim pleev xim, cov menyuam siv cov log, cov khoom siv ua kom yooj yim, cov khoom siv lossis khoom siv hauv tsheb, khoom siv kho mob, khau, nplaum, ntim, thiab hauv av yog txhua tus ua nrog polyurethanes.
Roj Hmab
Zoo li polyurethane, roj hmab yog elastomer. Vim hais tias ntawm lawv cov yam ntxwv elastic, elastomers feem ntau thiab aptly tau piav raws li rubbery cov ntaub ntawv. Ntau tus neeg tseem tuaj yeem xav txog feem ntau ntawm cov khoom siv roj hmab tau txais los ntawm nws cov qauv ntuj, uas yog los ntawm cov organic latex tua tau los ntawm cov roj hmab ntoo, ntau dua li cov roj hmab hluavtaws ua los ntawm roj av los ntawm kev ua haujlwm. Txawm hais tias cov roj hmab organic tseem tau sau tseg rau siv, feem ntau ntawm cov khoom siv roj hmab tsim tawm niaj hnub no yog ua nrog cov roj hmab hluavtaws. Nyob rau hauv tag nrho, tom kawg tso nyiaj rau kwv yees li ob feem peb ntawm kev tsim khoom hauv ntiaj teb txhua xyoo.
Cov roj hmab yog zoo sib xws nrog cov log tsheb, thiab nws tsis muaj qhov xav tsis tau. Nws txoj kev ua kom yooj yim, thev taus thiab ua kom tawv los ua cov roj hmab ua cov khoom siv yooj yim rau kev tsim cov log tsheb rau lub tsheb, tsheb npav, tsheb thauj khoom, dav hlau, thiab tsheb kauj vab. Cov roj hmab feem ntau tsim tawm rau kev lag luam tsheb. Ib nrab ntawm tag nrho cov roj hmab tsim tawm mus rau qhov tsim cov log tsheb rau tsheb ib leeg. Qhov feem pua loj nkag mus rau cov khoom siv tshuab thiab cov sib xyaw xws li bushings, mountings, gaskets, hoses, thiab siv tawv. Lwm cov khoom siv roj hmab ua yog tsim rau cov neeg siv khoom siv xws li khau, khoom ua si, khaub ncaws, thiab rooj tog zaum.
