Txau Polyurea Elastomer (Txau Polyurea Elastomer, tom qab no hu ua SPUA) thev naus laus zis nyob txawv teb chaws kaum xyoo dhau los, cov txheej txheej muaj cov khoom siv siab, dej pleev xim txheej, hluav taws xob pleev xim txheej, hmoov txheej, xws li qis (tsis muaj) paug qias neeg tom qab txheej txheej tshuab , txhawm rau ua kom tau raws li ib puag ncig kev tsim kho thiab kev tsim kho, kev txhim kho ib hom tshiab ntawm cov kuab tshuaj tsis muaj kuab paug, kuab paug tsis pub dawb ntsuab siv tshuab, nws yog nyob rau hauv cov tshuaj tiv thaiv kev txhaj tshuaj molding (RIM) thev naus laus zis tsim ntawm lub hauv paus ntawm, nws cov khoom siv raw. tau tsim los ntawm cov tuam txhab Texaco / Huntsman hauv Tebchaws Meskas ua ntej xaus amino poly propylene oxide ether amino polyether (kawg), Lub npe lag luam yog Jeffamine. Xim muab tshuaj yog muaj li ntawm kawg amino polyether, kua amine saw extender, xim, muab tub lim thiab lwm tus neeg sawv cev (R), thiab lwm pab pawg tau npaj los ntawm cov tshuaj tiv thaiv ntawm isocyanate thiab oligomer diol lossis ternary cawv (A tivthaiv). Lub Cheebtsam A thiab R raug txau lossis nrum polyurea elastomers dhau los ntawm H series lub tshuab loj thiab gx-7 series tshuaj tsuag phom uas tsim hauv Gusmer, Asmeskas. Cov tshuab no yog rau cov tshuaj tiv thaiv nrawm nrawm, qhov txheej txheem cov khoom siv tsis muaj cov kuab tshuaj, kev kho sai yog nrawm, cov txheej txheem yog yooj yim, tuaj yeem yooj yim rau hauv qhov nce, qhov nkhaus saum npoo txau kaum millimeters tuab txheej tsis tau dai. SPUA thev naus laus zis tau tawg los ntawm cov kev txwv ntawm ib txwm muaj kev tiv thaiv ib puag ncig txheej txheem thev naus laus zis. Yog li no, thaum cov thev naus laus zis los, nws tau tsim kho sai heev.
SPUA thev naus laus zis yog "txheej txheem tshiab" txheej txheem technology, uas yog suav hais tias yog qhov kev pom zoo tshaj plaws hauv kev ua haujlwm ntawm kev siv cov tshuab thiab txheej txheej tom kawg ntawm xyoo pua 20th. Nws muab cov thev naus laus zis tshiab, cov khoom siv tshiab thiab cov thev naus laus zis tshiab, thiab yog ib qho kev hloov pauv ntawm txoj kev tsim kho tshiab hauv kev lag luam. Nws tau siv rau hauv North America thiab lwm lub tebchaws tau tsim rau ntau dua kaum xyoo, thiab kev lag luam xav tau muaj zog heev.
Polyurea yog ua los ntawm semi-prepolymer, amino-terminated polyether, amine saw extender thiab hais txog. Nws yog qhov tsis tshua muaj neeg hydrophobic, tsis cuam tshuam rau cov av noo ib puag ncig, thiab muaj peev xwm txawm txau rau dej (los yog dej khov) rau hauv zaj duab xis, nyob rau hauv ib puag ncig huab puag ncig muaj peev xwm yog ib qho kev tsim kho, tshwj xeeb tshaj yog kev ua tau zoo. Cov tsos ntawm polyurea kiag li tsoo lub tswv yim ib txwm ntawm antisepsis thiab kev tiv thaiv thiab teeb tsa tus qauv siab dua rau cov khoom siv tiv thaiv kev lag luam. Urea-coated saj zawg zog, ua nruj, nplua nuj xim, nws yog ntom, txuas ntxiv, tsis muaj nqaws, cais kiag li ntawm qhov cuam tshuam ntawm dej thiab oxygen hauv huab cua, tiv thaiv xeb thiab kev tiv thaiv kev ua tsis tiav. Nws muaj ntau lub zog xws li hnav-resisting, waterproof, poob siab tsis kam, qaug zog tsis kam, laus kuj, kub tsis kam, nuclear hluav taws xob tsis kam, thiab lwm yam, yog li nws tau siv dav. Tsis muaj kev xav txhua txhua hnub muaj qhov tshiab tshiab kev siv ntawm cov kws ua haujlwm SPUA cov khoom.
Polyurea thev naus laus zis yuav yog yav tom ntej ntawm Tuam Tshoj rau kev tsim kho cov vaj tsev loj, xws li kev tiv thaiv chemical, pipeline tiv thaiv kev tiv thaiv tsis zoo, Tubrog nkoj, kev kho qhov choj, kev tiv thaiv, kev tiv thaiv dej, pas dej ua ke lub zog, kev cog ru tsev, cov khoom tsim tawm, fender chaw tsim khoom thiab lwm yam, muab ib qho kev txhim kho tshaj dhau hwv tiv thaiv kev tiv thaiv, tsis muaj dej tsis haum, hnav tsis kam thiab cov ntaub ntawv kho kom zoo nkauj, thiab kev tsim kho yooj yim tshaj plaws thiab sai.
