Cov txheej txheem dejyog cov txheej txheem txheej txheej loj tshaj plaws uas siv thoob ntiaj teb thiab xav tias yuav loj hlob ntxiv raws li ib feem pua ​​​​ntawm tag nrho cov txheej txheem txheej txheem. Los ntawm 2022, lubntiaj teb no ua lag luam lojntawm cov txheej txheem dej yuav tsum yog tshaj $ 146 billion USD. Kev loj hlob nyob rau hauv loj ib feem yog vim nce ntim hauv kev tsim kho thiab kev lag luam tsheb nrogacrylicsyog ib hom dej loj tshaj plaws ntawm cov khoom siv dej uas sawv cev rau ntau dua 80% ntawm tag nrho cov dej ua lag luam.

Qhov no yog Athena.MIT-IVY INDUSTRY feem ntau koom nrog cov dej-raws li kev lag luam xim, Kuv paub tias koj xav tau cov khoom zoo, pheej yig tus nqi thiab cov khoom siv txhawb nqa, peb muaj ISO certification, tshwj xeeb tshaj yog cov khoom catalog nrog tus nqi. Peb tsuas yog ntseeg siab zoo,

Thiab hauv peb cov neeg siv khoom txaus siab. Yog koj xav nug, thov hu rau kuv. ️ Tiv tauj peb:

Tsav tshebRau kev siv ntau dua ntawm cov txheej txheem dej muaj xws li:

• Lower VOC
• Yooj yim ntawm kev ntxuav hauv feem ntau
• Txo hluav taws kub txaus ntshai
• Tus nqi pov hwm qis dua
• Tsawg zog siv rauci txheejvim qhov xav tau qhov cub tsawg ua kom cua
• Qhov kev xav tau ntawm kev txo qis ntawmroj av- raws li cov ntaub ntawv.

Raws li lub Tsib Hlis, 2014 Prospector tsab xov xwm ntawmFlow, Leveling thiab viscosity Control nyob rau hauv dej-raws li txheejqhia tau hais tias, ob chav loj tshaj plaws ntawm cov txheej txheem dej muaj xws lidej-txothiablatex, nrog rau feem ntau ntawm ci coatings ntog nyob rau hauv thawj qeb nrog feem ntau ntawm cov architectural coatings teej tug mus rau lub thib ob qeb. Lub sij hawmdej-txoyog siv rau resins ua nyob rau hauv hnyav thiab txo nyob rau hauv dej los tsim ib tug dispersion ntawm resin nyob rau hauv dej.Latexresins ntawm qhov tod tes yog npaj los ntawm emulsion polymerization hauv dej.

Qhov tsis zoo rau kev siv cov txheej txheem dej muaj xws li:

• High dependence ntawm evaporation tus nqi ntawm cov txheeb ze humidity
• Kev kub siab ntawm evaporation rau dej yuav tsum tau 2260 J / g rau dej thiab piv txwv li tsuas yog 373 J / g rau2-butoxyethanol, ib tug nquag sivcosolvent
• Nonlinear viscosity txo nkhaus rau coatings siv dej txo resins
• High dependence ntawm ntws thiab tsos ntawm tus txheeb ze humidity
• High nto nro ntawm dej (poorer wetting) yuav tsum tau ntxiv ntawmsurfactantsuas nyob rau hauv ntau yam detracts los ntawm humidity kuj
• Waterborne coatings yog corrosive ntau tshaj li hnyav yug coatings thiab yog li yuav tsum tau lined ntim, yas los yog stainless hlau kom tsis txhob xeb.
• Cov txheej txheem dej muaj ntau dua tuaj yeem ua rau hauv daim ntawv thov ci vim tias kev tsim cov yeeb yaj kiab pib tshwm sim ua ntej dej evaporates los ntawm zaj duab xis (saib Table I)

Txawm li cas los xij, txuas ntxiv kev nce qib hauv cov ntaub ntawv tshawb fawb kom suav nrog kev tsim kho tshiab hauv resin chemistry, surfactants,cov neeg ua dej ntub dejthiabcov neeg khiav dej numyuav pab kom muaj kev loj hlob ntxiv ntawm cov txheej txheem dej.

Daim duab kuv sawv cev rau ntau theem hauv kev ziab ntawm cov xim pleev xim latex. Thawj theem yog evaporation ntawm dej. Qhov thib ob theem suav nrog qhov txuas ntxiv evaporation ntawm cov dej thiab cov cosolvent mus rau qhov chaw uas cov latex particles kov thiab pib coalescence los ua ib zaj duab xis uas yog ib nrab qhuav.

Cov theem kawg suav nrog kev sib txuas ntxiv thiab kev kho mob (hauv kev sib txuas sib txuas) los tsim cov yeeb yaj kiab kho, qhuav adherent xim.

Ib qho ntawm cov kev xav tseem ceeb hauv kev siv cov txheej txheem dej yog lub luag haujlwm kom cov av noo ntxiv rau qhov kub thiab txias plays hauv daim ntawv thov thiab kho cov txheej txheem no. Piv txwv li, txhawm rau muab cov khoom siv tau zoo, ob qho tib si kub thiab av noo yuav tsum tau ua tib zoo tswj raws li tau piav qhia hauv daim duab II. Cov nyhuv ntawm cov av noo ntawm cov coatings uas muaj dej-organic hnyav yuav tsis raug ignored.

Piv txwv li, tus txheeb ze evaporation tus nqi (E) ntawm dej ntawm 0 - 5% RH ntawm 25 ° C yog 0.31, tab sis ntawm 100% RH tus E yog 0. E ntawm 2-butoxyethanol, ib tug nquag siv cosolvent, yog 0.077. Thaum qis RH, dej evaporates sai dua thiab yog li qhov piv ntawm 2-butoxyethanol rau dej nce; qhov thim rov qab yog qhov tseeb ntawm cov av noo siab.

Thaum siv cov txheej txheem dej, yog tias cov av tsis quav ntsej, kev hloov pauv ntawm cov khoom siv thiab cov tsos yuav tshwm sim. Piv txwv li yog tias qhov kub ntawm daim ntawv thov xyoo puag ncig yog 70 ° - 80 ° F, daim ntawv thov qhuav (tsis ntws) yuav ua rau lub caij ntuj no vim cov av qis tshwj xeeb tshaj yog nyob rau hauv cov huab cua txias thiab cov dej ntws ntau dhau yuav raug pom nyob rau lub caij ntuj sov (cov av noo siab) . Ib qho piv txwv ntawm qhov teeb meem tom qab yog tias ntawm li 65% Kwv Tij Humidity / 25 ° C, cov txheej txheem dej uas muaj 10.6% 2-butoxyethanol ntawm volatiles, evaporation tus nqi ntawm cov dej thiab 2-butoxyethanol yog sib npaug. Qhov txheeb ze humidity no hu ua Critical Relative Humidity.

Daim duab II Daim ntawv thov kev vam khom ntawm cov txheej txheem dej ntawm cov av noo thiab kub.

Cov lus kuv piav qhia txog qhov muaj kev vam khom ntawm cov txheej txheem dej ntawm cov dej ntws ntawm ntau cov yeeb yaj kiab thicknesses thaum piv rau cov kuab tshuaj yug los.

Table I Critical Film Thickness for Popping in Microns, Organic Coatings, Wiley-Interscience, 2007, Zeno W. Wicks Jr., Frank N. Jones, S. Peter Pappas, Douglas A. Wicks

Waterborne coatings muaj xws li ntau yam resin hom xws liacrylic xim,alkyd,tshuaj urethane,polyester,epoxy,tshuaj fluoropolymer, waterborne hmoov zoo li kho chemistry suav nrogUV kho,aminoplasttshuaj urethane,epoxy-polyamide,oxidativethiabcua qhuav thermoplastichom. Raws li Table II qhia, particle loj thiab particle architecture (xws li core plhaub) kuj pab txhawb rau qhov kawg zaj duab xis cov khoom ntawm txheej. Hauv cov ntsiab lus, ib zaug cov teeb meem tshwj xeeb cuam tshuam nrog kev siv cov txheej txheem dej tau pom zoo tias lawv muaj kev ua tau zoo hauv ntau yam kev siv.
