Ib hom tshiab ntawm "universal" txheej tshuab
Kev taw qhia
Polyurea yog ib hom tshuaj uas tsim los ntawm cov tshuaj tiv thaiv ntawm isocyanate Cheebtsam thiab cov amino compounds. Cov khoom siv isocyanate tuaj yeem yog monomer, polymer, isocyanate derivative, prepolymer, thiab semi-prepolymer.
Polyurea yog ntau yam zoo heev. Nws daim ntawv thov teb tau muab faib raws li hauv qab no: kev tiv thaiv pob zeb rau 60%, tsheb hnav-tiv taus hauv ob sab phlu nyiaj rau 15%, steel qauv tiv thaiv corrosion rau 10%, ru tsev waterproofing nyiaj rau 10%, thiab lwm tus account rau 5%.
Polyurea yog txau rau ntawm qhov chaw los ntawm cov khoom siv raw xws li semi-prepolymer, amino-terminated polyether, thiab amine chain extender. Nws yog hydrophobic heev thiab insensitive rau ib puag ncig humidity. Nws tuaj yeem muab txau rau hauv dej (lossis dej khov) los ua ib zaj duab xis. Nws tuaj yeem tsim tau ib txwm nyob rau hauv ib puag ncig hnyav hnyav, thiab nws qhov kev ua tau zoo tshwj xeeb tshaj yog. Qhov tshwm sim ntawm polyurea kiag li tsoo lub ntsiab lus ntawm kev tiv thaiv corrosion thiab kev tiv thaiv thiab teeb tsa tus qauv siab dua rau kev lag luam tiv thaiv cov khoom. Polyurea txheej yog hloov tau, nruj, thiab muaj yeeb yuj. Nws yog ntom, nruam, thiab seamless. Nws tag nrho thaiv qhov nkag mus ntawm cov dej noo thiab oxygen hauv huab cua thiab muaj qhov tsis sib xws los tiv thaiv corrosion thiab tiv thaiv cov khoom. Nws kuj muaj ntau yam kev ua haujlwm, xws li hnav tsis kam, tsis muaj dej tsis zoo, cuam tshuam tsis kam, qaug zog tiv thaiv, kev laus ua haujlwm, kub kub tsis kam, hluav taws xob hluav taws xob, thiab lwm yam, yog li nws muaj ntau yam kev siv. Tsis xav tias engineers nrhiav tau tej yam yees siv tshiab siv rau SPUA cov ntaub ntawv txhua hnub.
Raws li kev siv thev naus laus zis, polyurea thev naus laus zis feem ntau yog siv hauv plaub qhov loj: kev tiv thaiv dej, tiv thaiv corrosion, tiv thaiv abrasion, thiab kho kom zoo nkauj.
Cov yam ntxwv
1. Peb cov khoom siv tsim khoom sawv cev rau nws cov khoom tshwj xeeb. Nws kho sai heev, tsis tas yuav tsum tau catalysts. Nws tuaj yeem siv rau txhua qhov chaw, yog nws nkhaus, inclined, lossis ntsug, tsis muaj sagging. Nws tsim cov gel hauv tsuas yog 5 vib nas this thiab ncav cuag lub zog taug kev hauv 1 feeb xwb.
2. Nws tsis rhiab rau cov dej noo thiab kub thiab tsis cuam tshuam los ntawm ambient kub thiab av noo thaum lub sij hawm tsim kho (nws tuaj yeem tsim tau ntawm -28 degree; nws tuaj yeem txau thiab kho rau dej khov).
3. Peb cov khoom siv yog ob qho tib si, 100% cov ntsiab lus ntawm cov khoom siv. Nws yog dawb los ntawm volatile organic compounds (VOCs), ua rau nws ib puag ncig tus phooj ywg thiab tsis muaj kuab paug xaiv rau kev tsim kho. Nws tseem muaj kev nyab xeeb rau kev tu cev, ua kom muaj kev noj qab haus huv thiab kev noj qab haus huv ntawm koj cov neeg ua haujlwm.
4. Thermal spraying los yog pouring: lub thickness ntawm ib qho kev tsim kho tuaj yeem nyob ntawm ntau pua microns mus rau ob peb centimeters, kov yeej qhov tsis zoo ntawm ntau qhov kev tsim kho yav dhau los.
5. Cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, muaj zog tensile feem ntau, yoog raws, hnav tsis kam, tiv thaiv plam, kev laus, thiab corrosion kuj.
6. Nws muaj thermal stability zoo, tuaj yeem siv tau ntev ntawm 120 degree, thiab tuaj yeem tiv taus lub sijhawm luv luv thermal shock ntawm 350 degree.
7. Cov qauv tsim muaj kev tsim tawm zoo; cov txheej yog nruam thiab ntom, tsis muaj seams thiab tsis muaj pinholes, thiab zoo nkauj, tswv yim, thiab ruaj khov.
8. Peb cov khoom siv yog tsim los rau kev ua haujlwm zoo. Nws los nrog cov cuab yeej ua tiav, ua rau cov txheej txheem tsim kho tau zoo heev. Nws tuaj yeem ua tiav qhov tsim tsim thickness hauv ib lub sijhawm tsim kho. Cov cuab yeej yog nruab nrog ntau hom kev hloov pauv, tso cai rau ob qho tib si txau thiab nchuav. Ntxiv rau, kev tswj cov txheej txheem tsim ua kom muaj kev tiv thaiv kev poob siab, ntxiv rau nws cov kev ua tau zoo thiab kev nyab xeeb.
9. Nws muaj qhov adhesion zoo thiab tuaj yeem txau rau ntawm txhua lub substrate, xws li steel, ntoo, pob zeb, thiab lwm yam.
Spray Polyurea Elastomer (tom qab no hu ua SPUA) thev naus laus zis tau tsim tawm txawv teb chaws nyob rau hauv kaum xyoo dhau los, ua raws li cov txheej txheem qis (tsis muaj) cov pa phem xws li cov txheej txheem siab, dej-raws li txheej, hluav taws xob curing coatings, hmoov txheej, thiab lwm yam. , txhawm rau hloov mus rau kev tiv thaiv ib puag ncig. Ib qho tshiab hnyav-dawb, tsis muaj kuab paug ntsuab siv tshuab tsim raws li kev xav tau ntawm kev lag luam. Nws yog tsim los ntawm cov tshuaj tiv thaiv txhaj tshuaj molding (RIM) tshuab. Nws cov khoom tseem ceeb yog cov amino-terminated amino acid ua ntej tsim los ntawm American tuam txhab Texaco/Huntsman. Polyoxypropylene ether (amino-terminated polyether), lub npe hom yog Jeffamine. Cov txheej txheem no yog cov tshuaj tua kab mob ceev ceev. Cov khoom siv raw khoom tsis muaj cov kuab tshuaj, muaj kev kho sai sai, thiab yooj yim hauv cov txheej txheem. Nws tuaj yeem yooj yim tshuaj tsuag txheej ntawm ntau tshaj kaum millimeters tuab ntawm facades thiab nkhaus nto yam tsis muaj sagging.
Spua Technology Application
SPUA thev naus laus zis yog ib hom tshiab ntawm "universal" txheej thev naus laus zis thiab yog lub npe hu ua qhov kev tshawb pom loj tshaj plaws hauv cov txheej txheem txheej txheej thiab txheej txheej txheej txheej thaum xaus ntawm lub xyoo pua nees nkaum. Nws sib txuas cov thev naus laus zis tshiab, cov khoom siv tshiab, thiab cov txheej txheem tshiab thiab yog kev hloov pauv hloov pauv hauv kev tsim kho ib txwm siv thev naus laus zis. Nws tau siv nyob rau hauv cov teb chaws tsim xws li North America rau ntau tshaj kaum xyoo, thiab kev lag luam xav tau muaj zog heev.
Spua Technology Application
SPUA thev naus laus zis tau ua tiav dhau los ntawm cov kev txwv ntawm ib puag ncig tus phooj ywg pleev xim thev naus laus zis. Yog li ntawd, thev naus laus zis tau tsim kho sai sai thaum nws tawm los.
Tam sim no, nws tau raug lees paub thiab lees txais los ntawm tib neeg, thiab tau nyiam cov neeg nyiam thiab thim rov qab thoob ntiaj teb.twentieth century. Nws sib txuas cov thev naus laus zis tshiab, cov khoom siv tshiab, thiab cov txheej txheem tshiab thiab yog kev hloov pauv hloov pauv hauv kev tsim kho ib txwm siv thev naus laus zis. Nws tau siv nyob rau hauv cov teb chaws tsim xws li North America rau ntau tshaj kaum xyoo, thiab kev lag luam xav tau muaj zog heev.
