Kev piav qhia txog khoom
Polyurea yog ib qho tshuaj siv dav dav uas tau siv tau zoo hauv kev tiv thaiv xeb ntawm cov thoob dej cia khoom, kev tiv thaiv dej ntawm cov qauv pob zeb xws li chaw nres tsheb, pas dej, thiab qhov av, thiab ua cov khoom sib koom ua ke lossis cov khoom foob.
- Muaj ntau daim ntawv teev cov khoom siv uas siv los ua cov tshuaj pleev xim tiv thaiv dej. Tau ntau pua xyoo, tsuas muaj cov khoom siv ua los ntawm asphalt xwb. Hauv xyoo pua 20th, ntau lwm yam khoom siv tau tsim, suav nrog epoxy thiab vinyl ester.
- Polyurea yog cov txheej txheem txheej txheem tshiab tshaj plaws. Cov khoom siv no, tsim rau kev lag luam tsheb thaum xyoo 1980s, tam sim no siv dav hauv ntau qhov chaw. Vim nws kho sai, tiv taus corrosion, thiab tiv taus hnav, nws tau ua tiav kev vam meej hauv kev tsim dej tsis pub dej nkag hauv 10 xyoo dhau los.
- Thaum polyurea tau tsim tawm, nws tau cia siab tias yuav muaj cov khoom siv polyurethane uas tsis tshua muaj zog rau dej. Los ntawm kev hloov cov pawg carboxyl hauv polyurethane nrog cov pawg amino, cov khoom uas peb hu ua polyurea tam sim no tau txais. Cov khoom no tsis tshua muaj zog rau dej ntau dua li lwm cov txheej polyurethane.
- Polyurea muaj ob hom uas siv ntau. Aromatic polyurea siv ntau dua. Kev ua haujlwm ntawm cov khoom no tuaj yeem sib txawv ntau, yog li muaj ntau yam kev siv sib txawv. Qhov tseeb, qhov tsis zoo ntawm cov txheej no yog qhov tsis ruaj khov UV. Lwm hom yog aliphatic polyurea. Los ntawm kev siv cov txheej txheem tshuaj sib txawv kom nws muaj kev ruaj khov UV zoo dua, yuav raug nplua tus nqi. Tus nqi ntawm polyurea no feem ntau yog ob npaug ntawm aromatic polyurea.
Cov yam ntxwv ntawm cov khoom
Polyurea coatings, ua ib hom tshiab ntawm kev ua haujlwm siab, muaj ntau yam ntxwv zoo kawg nkaus.
- Nws muaj cov khoom zoo heev, xws li kev tiv thaiv kev hnav zoo, uas ua rau lub txheej txheej no khaws nws qhov kev ncaj ncees thiab kev tiv thaiv ntev txawm tias nyob rau hauv ib puag ncig uas muaj kev sib txhuam thiab kev hnav ntau zaus;
- Tib lub sijhawm, nws muaj kev tiv thaiv kev cuam tshuam zoo heev, tiv taus kev cuam tshuam sab nraud thiab tiv thaiv qhov chaw ntawm cov khoom coated los ntawm kev puas tsuaj.
- Hais txog cov khoom siv tshuaj lom neeg, cov txheej polyurea ua rau pom kev tiv thaiv corrosion zoo heev. Txawm tias ntsib kev puas tsuaj ntawm cov kua qaub, alkalis, lossis hauv cov chaw muaj tshuaj lom neeg hnyav xws li cov av noo siab thiab cov tshuaj tsuag ntsev ntau, lawv tuaj yeem ruaj khov rau lub sijhawm ntev thiab tsis yooj yim rau cov tshuaj lom neeg uas ua rau cov txheej puas tsuaj.
- Ntxiv mus, nws muaj kev tiv thaiv huab cua zoo, tswj nws qhov kev ua tau zoo nyob rau hauv ntau yam huab cua, xws li qhov kub siab, qhov kub qis, thiab ultraviolet hluav taws xob, yam tsis muaj teeb meem xws li hmoov av, xim tsis zoo, lossis tev tawm vim muaj kev hloov pauv huab cua. Qhov ceev kho ntawm polyurea coatings yog ceev heev, uas ua rau kev tsim kho zoo dua thiab ua rau cov txheej txheem tiav thiab siv tau hauv lub sijhawm luv luv.
- Tsis tas li ntawd xwb, nws muaj kev nplaum zoo rau ntau yam khoom siv, muaj peev xwm nplaum tau zoo rau ntawm cov hlau, pob zeb, ntoo, thiab lwm yam, tsim ib txheej tiv thaiv ruaj khov thiab ruaj khov.
COV KHOOM ZOO TSHAJ PLAWS
- Ib qho ntawm cov laj thawj uas ua rau cov txheej polyurea tau nrov sai yog lawv cov yam ntxwv zoo heev. Lub vev xaib Polyurea.com tau hais tias hais txog cov yam ntxwv ntawm lub cev muaj, tsis muaj lwm cov txheej hauv ntiaj teb tuaj yeem sib piv polyurea. Los ntawm kev kho cov mis, cov khoom polyurea tuaj yeem muaj ntau yam ntxwv, los ntawm kev ntev mus rau lub zog tensile zoo heev, tab sis qhov no cuam tshuam nrog cov mis ntawm cov khoom siv thiab kev siv kom raug. Polyurea muaj kev sib txuas zoo rau ntau yam substrates suav nrog cov pob zeb, hlau, thiab ntoo, txawm tias tsis muaj primer, thiab tuaj yeem siv rau hauv cov chaw uas muaj ntau qhov kub thiab txias thiab av noo sib txawv. Tej zaum qhov zoo tshaj plaws ntawm polyurea yog nws txoj kev kho sai heev. Thaum siv, polyurea tuaj yeem ncav cuag qhov tuab xav tau hauv ib txheej, uas yog ntau zaus sai dua li siv cov txheej ib txwm muaj, tso cai rau tus tswv rov qab siv lub chaw thiab txo qhov poob vim lub sijhawm tsis ua haujlwm.
- Qhov tuab ntawm ib daim ntawv thov ntawm polyurea txheej tuaj yeem yog txij li 0.5 hli txog 12.7 hli, thiab lub sijhawm kho yog txij li tam sim ntawd mus txog kwv yees li 2 feeb, uas yog qhov zoo rau kev ncav cuag lub xeev siv tau sai.
- Ua ib txheej txheej tuab uas kho sai, thaum xav tau ib daim ntaub thaiv dej tsis muaj dej thiab ruaj khov, polyurea yog qhov kev xaiv zoo tshaj plaws. Lwm yam khoom, xws li xav tau kev tiv thaiv kev plam thiab kev ntxhib los mos ntawm qhov chaw, kuj tuaj yeem ua tiav los ntawm qee txoj kev. Cov txheej txheej no tuaj yeem pleev xim thiab txawm tias siv tau rau hauv cov chaw uas ua tau raws li qhov yuav tsum tau ua ntawm dej haus.
- Vim nws muaj ntau yam kev ua tau zoo, polyurea muaj ntau yam kev siv. Sab hauv ntawm cov thoob dej cia khoom, cov txheej tiv thaiv thib ob, thiab kev tiv thaiv ntawm cov choj yog cov sijhawm siv dav tshaj plaws rau hom khoom siv no. Qhov tseeb, qhov ua tau ntawm kev siv polyurea yuav luag tsis muaj kev txwv.
- Cov thoob dej ntawm cov chaw kho dej khib nyiab feem ntau raug kev txom nyem los ntawm vortex, scouring, thiab ntau cov pa roj hydrogen sulfide thaum lub sijhawm lim, sib tov, thiab dehydration. Kev siv polyurea tuaj yeem muab cov khoom tiv thaiv kev hnav, kev tiv thaiv tshuaj lom neeg, thiab kev tiv thaiv kev cuam tshuam, thiab tuaj yeem rov qab ua haujlwm ntawm lub Hoobkas sai sai, uas yog sai dua li ntau lwm txoj hauv kev.
- Thaum siv rau cov choj thiab lwm qhov chaw uas raug kev co thiab kev hloov chaw, qhov yooj ywm ntawm polyurea yog lwm qhov zoo dua li cov txheej txheej nyias dua thiab tsis yooj ywm xws li epoxy.
Cov Khoom Tsis Zoo
- Tau kawg, polyurea kuj muaj qee qhov tsis zoo. Cov khoom siv uas xav tau rau kev siv cov txheej polyurea kim heev, txij li $ 15,000 txog $ 50,000 lossis siab dua. Lub platform tsim kho mobile uas muaj tag nrho cov khoom siv tuaj yeem raug nqi txog $ 100,000.
- Tus nqi ntawm cov ntaub ntawv polyurea kuj siab dua li lwm cov txheej txheej. Tus nqi pib siab dua li ntawm epoxy. Txawm li cas los xij, txij li thaum lub neej ua haujlwm ntawm polyurea txheej yog 3 txog 5 npaug ntawm lwm cov khoom, qhov kev siv nyiaj tau zoo thaum lub sijhawm ua haujlwm tseem muaj qhov zoo.
- Ib yam li lwm yam khoom siv tiv dej, kev tsim kho tsis raug kuj tuaj yeem ua rau daim ntawv thov tsis ua haujlwm. Txawm li cas los xij, qhov yuav tsum tau ua rau kev tsim kho nrog polyurea coatings yog qhov siab heev. Kev kho qhov chaw xws li sandblasting lossis priming yog qhov tseem ceeb heev rau polyurea. Feem ntau cov haujlwm polyurea coating tsis ua haujlwm yuav luag tsis muaj feem cuam tshuam nrog polyurea nws tus kheej, tab sis yog tshwm sim los ntawm kev kho qhov chaw tsis raug lossis tsis zoo.
Kev Tsim Kho
- Feem ntau cov polyurea siv rau kev tiv thaiv dej yog tsim los ntawm kev siv cov khoom siv txau ntau yam. Feem ntau, siv ob lub tshuab, nrog rau cov amino resin sib xyaw thiab cov khoom siv isocyanate sib cais hauv cov thawv 50-gallon. Thaum lub sijhawm tsim kho ntawm qhov chaw ua haujlwm, cov ntsiab lus ntawm cov thawv 50-gallon raug xa mus rau lub tank ntawm cov khoom siv txau thiab cua sov rau qhov kub tsim nyog (60-71 ° C). Tom qab ntawd, cov isocyanate thiab cov polyol resin raug xa mus los ntawm lub raj cua sov mus rau rab phom txau.
- Qhov piv ntawm ob yam khoom no raug tswj hwm nruj me ntsis, feem ntau ntawm qhov piv 1:1.
- Lub sijhawm kho ntawm polyurea yog ntsuas hauv vib nas this, yog li cov tshuaj no tsuas yog tuaj yeem sib xyaw thaum lawv tawm hauv rab phom tsuag; txwv tsis pub, lawv yuav kho thiab tawv hauv rab phom tsuag.
- Muaj ib txhia chaw tsim khoom muag cov tshuab txau tshuaj uas txav tau tag nrho, suav nrog txhua yam cuab yeej thiab khoom siv, uas tau teeb tsa rau ntawm cov tsheb laij teb lossis cov txaj tsheb thauj khoom.
