Yuav ua li cas yogpolyurethane sib xyaw polyolsiv hauv kev thauj mus los thiab cov khoom siv dej?
Ntxiv nrog rau cov ntaub ntawv rwb thaiv tsev rau cov tsheb thauj mus los hauv tub yees, cov khoom siv polyurethane ua npuas ncauj kuj tseem siv rau hauv lwm cov khoom siv hauv tsheb, tsheb ciav hlau, nkoj thiab lwm yam tsheb.
Polyurethane txhav ua npuas ncauj yog tam sim no dav siv nyob rau hauv tsheb qab nthab thiab sab hauv qhov chaw. Yav dhau los, nws yog tsim los ntawm cov ntaub los yog polyvinyl chloride zaj duab xis thiab polyurethane mos ua npuas ncauj. Tam sim no, Polyurethane txhav ua npuas ncauj cov ntaub ntawv yog siv, xws li cam khwb cia nyuaj ua npuas ncauj, tshuaj tsuag tawv ua npuas ncauj, iav Fiber-reinforced rigid ua npuas ncauj thiab thermoformed rigid ua npuas ncauj nplooj ntawv thiab thermo-pressed composites ntawm zoo nkauj fabrics, thiab lwm yam ntawm qhib-cell ua npuas ncauj pab txhim kho lub tsheb sib dhos efficiency, thiab nws lub zog, seem stability, thermal rwb thaiv tsev, suab haum, thiab lwm yam yuav ua tau raws li qhov yuav tsum tau ntawm kev siv.
Rigid polyurethane structural ua npuas ncauj yog siv nyob rau hauv ntau yam automotive Cheebtsam, xws li lub qhov rooj vaj huam sib luag, trunk hau, cav hoods, thiab lwm yam Lub tsheb ciav hlau siv Polyurethane rigid ua npuas ncauj rau thermal rwb thaiv tsev, thiab cov nyhuv yog zoo kawg li.
PU rigid ua npuas ncauj kuj tseem siv los ua cov khoom siv thermal rwb thaiv tsev rau cov tsheb tub yees, cov thawv txias, thiab lwm yam, uas tuaj yeem ua kom ntseeg tau tias qhov kub ntawm cov khoom noj khov yog nyob rau hauv qhov yuav tsum tau ua thaum thauj mus los ntev. Nws kuj tseem siv tau los ua cov khoom siv rwb thaiv tsev rau cov tsheb thauj khoom cua txias.
Rigid foam plastics kuj tseem siv los ua cov ntaub ntawv pov thawj cryogenic rau cov nkoj roj liquefied thiab cov roj liquefied roj cia tank. Lawv muaj tus nqi qis gasification thiab zoo dua li cov ntxhia wool thiab lwm yam khoom siv thermal rwb thaiv tsev.
Thaum tsim kev tsheb ciav hlau thiab txoj kev loj hauv thaj chaw permafrost thiab cov av khov nyob rau lub caij ntuj sov, yuav tsum tau ua raws li kev tiv thaiv khov kho kom tsis txhob muaj huab cua sov los yog melting kev puas tsuaj rau txoj kev noob, uas yuav ua rau poob loj. Rigid polyurethane ua npuas ncauj tau siv los ua cov khoom siv rwb thaiv tsev hauv cov chaw permafrost ntawm Qingkang Txoj Kev Loj thiab Qinghai-Tibet Railway hauv kuv lub tebchaws. Muaj ob txoj kev tsim kho rau kev siv cov nplaum polyurethane ua npuas ncauj rau ntawm txoj kev: tso cov nplaum nplaum thiab cov txheej txheem txau rau ntawm qhov chaw.
Polyurethane txhav ua npuas ncauj nrog kaw cell qauv siv tau los ua cov khoom ntim ntawm lifebuoys thiab muaj qhov zoo ntawm lub teeb yuag, siab zog thiab dej tsis kam. Filled polyurethane fender (pob) yog lub teeb yuag ntab fender system uas siv lub teeb yuag, tawv thiab ua npuas ncauj ua npuas ncauj li qhov nruab nrab buffering. Nws muaj lub zog nqus zoo dua li cov fenders inflatable, yog lub teeb yuag thiab hloov tau yooj yim, thiab tau siv dav hauv yachts, nkoj me, Nkoj-rau-nkoj ua haujlwm xws li nkoj nkoj.
