Txheej Polyurea rau kev kho dua tshiab ntawm phab ntsa: Ib qho kev xaiv tshiab uas zoo rau ib puag ncig thiab ua haujlwm tau zoo rau cov tsev
Nyob rau hauv lub ntsiab lus ntawm kev loj hlob tas mus li ntawm kev thov rau kev kho dua tshiab hauv nroog thiab kev kho dua tshiab lub tsev qub, ib hom tshiab ntawm cov khoom siv txheej phab ntsa uas sib xyaw ua ke kev phooj ywg ib puag ncig, kev ruaj khov thiab kev zoo nkauj - polyurea txheej - maj mam dhau los ua "nyiam tshiab" hauv kev lag luam kev tsim kho. Tsis ntev los no, cov haujlwm kho dua tshiab ntawm cov chaw nyob qub hauv ntau thaj chaw tau siv cov txheej txheem polyurea txheej ua ntej, muab cov kev daws teeb meem tshiab rau kev kho dua tshiab phab ntsa.
Kev Tsim Kho Tshiab: Cov txiaj ntsig "Core" ntawm Polyurea Coatings
Cov txheej Polyurea yog ib hom khoom siv elastomer uas tsim los ntawm kev sib xyaw ntawm cov khoom isocyanate thiab cov amino compounds. Lawv muaj cov yam ntxwv xws li kev kho sai heev, elasticity siab, tiv taus corrosion, thiab cov khoom tiv thaiv kev laus. Piv rau cov xim latex ib txwm muaj, cov vuas ceramic, thiab lwm yam khoom siv kho dua tshiab, lawv cov kev ua haujlwm tsim kho tau nce 3-5 zaug. Ib daim ntawv thov tuaj yeem ua tiav ntau yam haujlwm xws li kev tiv thaiv dej, tiv thaiv pwm, thiab tiv thaiv kev hnav, thiab tsis tas yuav tsum tau saib xyuas ntau zaus. Lawv lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 10 xyoo.
Kev txhawb nqa ib puag ncig: Kev tsim kho ntsuab pab txhawb rau kev txhim kho kom ruaj khov
Cov yam ntxwv ib puag ncig ntawm cov txheej polyurethane kuj tau nyiam ntau qhov kev saib xyuas. Thaum lub sijhawm tsim kho, lawv tsis tso tawm VOCs (cov organic compounds volatile), zam cov ntxhiab tsw phem thiab huab cua uas tshwm sim thaum lub sijhawm tsim kho cov txheej ib txwm muaj; tib lub sijhawm, cov khoom siv nws tus kheej tuaj yeem rov ua dua tshiab, ua tau raws li qhov yuav tsum tau ua ntawm "dual carbon" txoj kev npaj rau kev hloov pauv ntsuab ntawm kev lag luam tsim kho. Cov kws tshaj lij los ntawm Tuam Tshoj Academy of Building Research tau taw qhia tias: "Kev txhawb nqa cov txheej polyurethane yog ib qho cim tseem ceeb ntawm kev hloov pauv hauv kev kho dua tshiab ntawm lub tsev los ntawm 'kev hais txog cov txiaj ntsig' mus rau 'kev hais txog cov txheej txheem'."
Kev nthuav dav ntawm daim ntawv thov: Kev them nqi ntau yam los ntawm kev nyob hauv tsev mus rau kev lag luam
Tam sim no, cov thev naus laus zis tshiab ntawm polyurea coatings tau siv dav hauv cov zej zog nyob, cov tsev lag luam, cov nroj tsuag kev lag luam, thiab lwm yam teb. Hauv cov xwm txheej kev lag luam, nws cov kua qaub thiab alkali tsis kam, nrog rau kev cuam tshuam tsis kam, tuaj yeem ua tau zoo rau cov chaw nyuaj xws li cov nroj tsuag tshuaj thiab cov tsev rau khoom; hauv cov xwm txheej kev lag luam, cov txheej txheem elastic heev tuaj yeem hloov kho rau qhov kev hloov pauv me me ntawm cov qauv tsev thiab zam kev tawg thib ob.
Txij li "kho" mus rau "hloov kho dua tshiab", cov txheej polyurethane siv lub zog thev naus laus zis los hloov kho "qib tsos" thiab "kev noj qab haus huv" ntawm cov tsev hauv nroog. Tsav los ntawm kev txhawb nqa txoj cai thiab kev thov ntawm kev ua lag luam, cov khoom siv tshiab no yuav ua rau muaj kev hloov pauv tom ntej hauv kev kho dua tshiab phab ntsa.
