Hauv thaj tsam ntawm cov txheej txheem thiab cov xim, cov neeg ua hauj lwm qib ua lub luag haujlwm tseem ceeb hauv kev ua tiav kev sib luag, zoo ib yam, thiab qhov tsis xws luag - dawb tiav. Raws li tus neeg muag khoom qib theem, kuv tau pom ua ntej txog ntau yam kev xav tau ntawm kev lag luam sib txawv thiab cov yam ntxwv ua tau zoo ntawm ntau tus neeg ua haujlwm qib. Hauv qhov blog no, kuv yuav tshawb nrhiav qhov sib txawv ntawm ntau hom kev sib txawv ntawm cov neeg ua haujlwm sib txawv, ua kom pom kev ntawm lawv cov khoom, kev siv, thiab lawv yuav ua li cas zoo tshaj plaws rau koj cov kev xav tau txheej.
Chemical Composition thiab Structure
Ib qho ntawm qhov sib txawv ntawm cov neeg ua hauj lwm qib yog nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg. Muaj ntau pawg tseem ceeb, suav nrog silicone - raws, acrylic - raws, thiab fluorocarbon - raws li cov neeg ua haujlwm qib.
Silicone - raws li cov neeg ua haujlwm theem tau zoo - paub txog lawv cov dej num zoo heev. Lawv feem ntau muaj cov pob txha silicone nrog ntau pawg organic txuas. Cov saw hlau silicone muab qhov nro qis, uas tso cai rau tus neeg sawv cev kis tau sai sai thoob plaws txheej txheej. Qhov kev sib kis sai sai no pab tshem tawm qhov tsis xws luag xws li txiv kab ntxwv tev, craters, thiab txhuam cov cim. Piv txwv li, hauv automotive topcoats, silicone - raws li leveling agents tuaj yeem tsim ib lub siab - gloss, iav - zoo li tiav. Lawv cov qauv molecular tshwj xeeb kuj tseem ua rau muaj kev cuam tshuam zoo thiab tiv thaiv - thaiv cov khoom, uas muaj txiaj ntsig zoo hauv cov ntawv thov uas cov chaw coated tuaj yeem sib cuag nrog ib leeg thaum tuav lossis khaws cia.
Acrylic - raws li tus neeg sawv cev theem, ntawm qhov tod tes, yog cov polymers tau los ntawm acrylic monomers. Lawv feem ntau sib xws nrog ntau yam txheej txheej resins piv rau silicone - raws li cov neeg ua haujlwm. Acrylic leveling cov neeg ua haujlwm tuaj yeem txhim kho qhov ntws thiab theem ntawm cov txheej txheem los ntawm kev txo cov kev sib txhuam sab hauv hauv cov zaj duab xis txheej. Lawv feem ntau siv nyob rau hauv architectural coatings, qhov twg lawv pab kom ua tiav ib tug du thiab txawm tag rau ntawm phab ntsa thiab qab nthab. Lawv compatibility nrog dej - raws thiab hnyav - raws systems ua rau lawv muaj ntau yam kev xaiv rau ntau txheej formulations.
Fluorocarbon - raws li cov neeg ua haujlwm theem muaj qhov nro qis tshaj plaws ntawm peb hom no. Cov pa roj carbon muaj zog - fluorine bonds nyob rau hauv lawv cov qauv muab tshwj xeeb rau lawv cov dej thiab roj repellency, nrog rau zoo heev los tiv thaiv - cov khoom paug. Hauv cov txheej txheem kev lag luam, tshwj xeeb tshaj yog cov siv hauv siab - kev ua tau zoo xws li aerospace thiab marine coatings, fluorocarbon - raws li cov neeg ua hauj lwm theem tuaj yeem muab kev tiv thaiv ntev - ntev tiv thaiv ib puag ncig hnyav. Txawm li cas los xij, lawv feem ntau kim dua li silicone thiab acrylic - raws li cov neeg ua haujlwm, uas txwv tsis pub lawv siv hauv qee qhov nqi - rhiab daim ntawv thov.
Cov yam ntxwv ua haujlwm
Nto Nrho Kev Txom Nyem
Txhua tus neeg ua haujlwm qib yog tsim los txo qhov nro ntawm cov txheej txheej, tab sis qhov kev txo qis sib txawv. Silicone - raws li cov neeg ua haujlwm tuaj yeem txo qhov nro ntawm qhov chaw, feem ntau ua tiav cov txiaj ntsig qis dua 20 mN / m. Qhov no ua rau lawv muaj txiaj ntsig zoo hauv kev txhawb nqa kev sib kis sai thiab qib, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem nrog cov viscosity siab. Acrylic - raws li cov neeg ua haujlwm feem ntau txo qhov nro saum npoo mus rau theem nrab, feem ntau yog nyob rau hauv thaj tsam ntawm 25 - 35 mN / m, uas yog txaus rau feem ntau - lub hom phiaj txheej txheej. Fluorocarbon - raws li cov neeg ua hauj lwm muab qhov kev txo qis ntawm qhov chaw siab tshaj plaws, ncav cuag qhov muaj nqis tsawg li 10 - 15 mN/m nyob rau qee kis, muab qhov tsis sib xws ntawm qib thiab tiv thaiv - kev sib kis.
Kev sib haum xeeb
Compatibility nrog txheej resin yog ib qho tseem ceeb. Silicone - raws li cov neeg ua hauj lwm tej zaum yuav ua rau muaj teeb meem kev sib raug zoo, tshwj xeeb tshaj yog nyob rau hauv tej yam dej - raws li systems los yog thaum siv ntawm high concentrations. Lawv tuaj yeem ua rau muaj teeb meem xws li hawb pob, ntses - ob lub qhov muag, lossis tsis zoo inter - lub tsho tiv no. Acrylic - raws li cov neeg ua haujlwm muaj kev sib raug zoo nrog ntau hom resins, suav nrog alkyds, polyurethanes, thiab acrylic resins lawv tus kheej. Qhov no ua rau lawv muaj kev ntseeg siab rau kev tsim cov txheej txheem nrog cov chemistry sib txawv. Fluorocarbon - raws li cov neeg sawv cev kuj tuaj yeem muaj kev sib tw sib tw vim lawv cov tshuaj lom neeg tshwj xeeb, tab sis kev xaiv thiab kev tsim kom zoo tuaj yeem txo cov teeb meem no.
Zaj duab xis Properties
Hom leveling tus neeg sawv cev siv kuj tuaj yeem cuam tshuam rau cov yeeb yaj kiab kawg. Silicone - raws li cov neeg ua haujlwm tuaj yeem ua kom cov gloss thiab smoothness ntawm txheej zaj duab xis. Lawv kuj tuaj yeem txhim kho mar thiab khawb tsis kam rau qee qhov. Txawm li cas los xij, qee zaum, lawv tuaj yeem txo qhov adhesion ntawm cov khaubncaws sab nraud povtseg yog tias tsis tsim nyog. Acrylic - raws li tus neeg sawv cev tuaj yeem txhim kho qhov yooj thiab hardness ntawm txheej zaj duab xis, thaum tuav zoo adhesion. Fluorocarbon - raws li cov neeg ua haujlwm tuaj yeem txhim kho cov dej thiab roj, nrog rau cov huab cua ntawm cov txheej, tab sis lawv yuav muaj kev cuam tshuam rau cov khoom siv ntawm cov yeeb yaj kiab yog tias siv ntau dhau.
Daim ntawv thov Scenario
Cov kev lag luam sib txawv muaj cov kev xav tau sib txawv rau cov neeg ua haujlwm qib.
Hauv kev lag luam tsheb, siab - gloss thiab khawb - resistant finishes yog qhov tseem ceeb. Silicone - raws li cov neeg ua haujlwm theem tau dav siv hauv tsheb clearcoats kom ua tiav qhov du, tsis xws luag - dawb nto nrog zoo gloss tuav. Lub peev xwm ntawm cov neeg ua haujlwm silicone los txo qhov kev sib txhuam ntawm qhov chaw kuj tseem pab txo qis qhov pom ntawm micro - khawb los ntawm kev ntxuav tsheb lossis ib puag ncig.
Architectural txheej yuav tsum ua kom zoo nkauj thiab ntev - kav ntev. Acrylic - raws li tus neeg sawv cev qib yog qhov kev xaiv nrov rau ob qho tib si sab hauv thiab sab nrauv phab ntsa. Lawv tuaj yeem muab qhov ua tiav du uas zais qhov tsis zoo ntawm qhov chaw, thiab lawv cov kev sib raug zoo nrog dej - cov txheej txheem ua rau lawv ib puag ncig zoo.
Hauv kev lag luam txheej txheej, tshwj xeeb tshaj yog rau kev siv xws li cov kav dej, txuas hniav, thiab cov tshuab hnyav, cov txheej txheem yuav tsum tau tiv taus ib puag ncig hnyav. Fluorocarbon - raws li cov neeg ua hauj lwm qib feem ntau tau muab tso rau hauv cov txheej txheem no los txhim kho lawv cov corrosion kuj, weatherability, thiab tus kheej - tu khoom.
Tus nqi - Kev Ntsuam Xyuas Cov txiaj ntsig
Thaum nws los txog rau kev xaiv tus neeg sawv cev theem, tus nqi - kev txheeb xyuas qhov txiaj ntsig yog qhov tseem ceeb. Silicone - raws li tus neeg sawv cev qib yog tus nqi - zoo. Lawv muab qhov sib npaug zoo ntawm kev ua tau zoo thiab tus nqi, ua rau lawv haum rau ntau yam kev siv. Acrylic - raws li tus neeg sawv cev kuj yog tus nqi tsim nyog, tshwj xeeb tshaj yog xav txog lawv cov kev sib raug zoo thiab ntau yam. Fluorocarbon - raws li tus neeg sawv cev yog qhov kim tshaj plaws, tab sis lawv cov kev ua tau zoo tshaj hauv siab - kawg daim ntawv thov tuaj yeem ua pov thawj tus nqi. Piv txwv li, nyob rau hauv aerospace coatings qhov twg lub durability thiab kev ua tau zoo yuav tsum tau siab heev, kev nqis peev nyob rau hauv fluorocarbon - raws li leveling agents yuav ua rau kom ntev - lub sij hawm txuag nyob rau hauv cov nqe lus ntawm txo cov txij nkawm thiab hloov cov nqi.
