1.What cov nyhuv twg yog cov menyuam txheej txheem txheej txheem muaj rau ntawm cov xim sib txawv?

Txheej Txheej (pem hauv kev vasating vs rov qab txheej): Rov qab txheej: Cov txheej txheej txheej puv ntawm kev coj rov qab ntawm cov sawb khiav.
Cov txiaj ntsig zoo: thinner thiab ntau cov txheej txheej me me, tuaj yeem txo cov kab txaij ntev ("cov menyuam cim"), du thiab zoo nkauj xim uniformity.
Daim Ntawv Thov: High-Precision Topcoat Topcoat Topcoat Topcoat Topcoat Txheej Txheem, Ntau Tshaj Plaws, Nws Cov Khoom Uas Tsis Txaus Ntseeg).
Forward txheej: cov txheej txheej txheej puv ua ke rau tib txoj kev taug qab raws li sawb khiav.
Qhov tsis zoo: Cov txheej yog thicker thiab yog nquag mus rau cov cim uas muaj tseeb. Cov khaub ncaws tuab yog cov tsis tau zoo, uas yuav ua rau lub teeb thiab kab txaij tsaus nti los yog xim sib txawv pom rau lub qhov muag liab qab.
Daim ntawv thov: Primer lossis tuab txheej nrog cov dej num tsawg.

 

Cov menyuam qhov raug thiab cov xwm txheej: kev khiav tawm: Cov menyuam ua haujlwm lossis kev sib txawv ntawm cov txheej txheem kab rov tav "(sib tshuam mus rau qhov kev coj ua).
Cov txheej txheem saum npoo av: Hnav, khawb, thiab paug (qhuav xim (ua kom qhuav) yuav ncaj qha rau saum npoo av, ua rau cov kab ua haujlwm ncaj qha, zoo li cov kab lossis flaky me ntsis.
Kev daws: zom / hloov cov menyuam tsis tu ncua thiab nruj me ntsis huv thiab tswj hwm nws.

Txheej txheej hnyav: Tswj kev hloov kho tas li los ntawm kev tswj qhov sib txawv ntawm cov txiv nkhaus ntawm chais, siab, nrawm sib txawv, thiab txheej viscosity.
Cov kev hloov pauv: kev hloov pauv hauv cov txheej txheem hnyav tuaj yeem ua rau muaj kev sib txawv hauv cov yeeb yaj kiab tuab, uas nyeg cuam tshuam:
Hwj lub zog: Cov yeeb yaj kiab nyias nyias thaj chaw yuav qhia tau los ntawm hauv qab (primer lossis cov xim substrate yog qhia).
Xim: Ci ntsa iab: Txawv hauv Filks Thickness ua rau cov xim sib txawv (tshwj xeeb rau pob tshab / transcent pigments).
Kev cuam tshuam hlau / Phaw Striaure: Variations hauv zaj duab xis tuab cuam tshuam rau cov kev sib txawv ntawm cov nyhuv pigments, ua rau tsis sib haum xeeb lossis xim txawv.

2.Hyog li cas ua ntej kev kho mob (hloov tshuaj rau kev hloov tshuaj) cuam tshuam rau kev sib cuam tshuam xim xim?

Tsis ncaj ncees huv: Ua tsis tiav dej lossis tsis muaj dej tsis txaus, uas tsis zoo yuav ua rau "qhov muag tsis zoo" lossis "ntses ntses", puas tsuaj los ntawm kev ua kom cov xim sib txuas.
Tsis muaj kev hloov pauv zaj duab xis: tsis sib xws, ntsuas kub, ua kom muaj zog ntawm cov yeeb yaj kiab sib xyaw, thiab cov khoom siv ntawm cov khoom siv ntawm cov kua nplaum nyias nyias, thiab cov khoom siv hluav taws xob tsis muaj zog rau hauv cov duab tshiab (ua rau hauv qab). Cov yeeb yaj kiab tuab yuav hloov cov yam ntxwv ntawm cov txheej hauv qab thiab cuam tshuam cov xim ntawm lub sab topcoat.

3.Yuav tus txheej txheem kho tau cuam tshuam rau xim stability?

Cov ris tsho kub: Qhov kub ntawm kab rov tav ntawm sab laug thiab sab xis ntawm qhov chaw kho kom zoo, thiab cov xim yog qhov yooj yim hloov pauv thaum lub sijhawm (xim sib txawv nrog thaj chaw ib txwm). Cov cheeb tsam uas raug nplua dhau: Kev sib txuas ntau dhau ntawm lub cob cov khaub ncaws yuav ua rau yi ye ua rau yellowing (tshwj xeeb yog xim xim), lossis xim decomposition thiab discoloration.
Kev hloov ntsuas kub ntev dua: Tsis khov ua kom sov rauv taws lossis kev hloov pauv PMT (peak hlau kub), uas ua rau sib txawv thiab xim txawv.
Kho lub sijhawm: Cov Sawb tsis nyob hauv cov tshuaj tiv thaiv txaus, thiab cov xim tsis txaus ntseeg), cuam tshuam cov xim sib txawv thiab cov xim sib txawv.

4.Qhov xaiv cov txheej txheej thiab cov txheej txheem haum?

Leveling: Cov xim nrog cov khoom tsis zoo yog qhov nyuaj rau tshem tawm cov me me tom qab cov txiv kab ntxwv rau cov menyuam yaus, thiab ua rau muaj kev kho thiab xim tsis sib xws thiab xim. Cov txheej txheem ua kom zoo: Kho cov kuab cua evaporation tus nqi thiab nce cov txheej kub (preheating) txhawm rau txhim kho qib.
Kev Tawm Tawm: Evaporation dhau sai tuaj yeem ua rau yooj yim ua rau "benard hlwb" thiab daim ntawv nees txaij qauv; Kev qeeb heev tuaj yeem yooj yim ua rau sagging thiab rhuav tshem kev sib dhos.
Xim Dispersion Stability: Cov xim pigment sedimentation thiab flocculation thaum lub sijhawm tsim khoom lossis kev khaws cia rau cov txheej txheem sab saud thiab qis dua ntawm cov xim. Yog tias siv yam tsis muaj txaus pluaj, nws yuav ua rau cov xim sib txawv hauv lossis nruab nrab.

 

5.Yuav ua li cas ua ib puag ncig thiab khoom siv cuam tshuam rau cov khaub ncaws xim xim?

Kev nyiam huv ntawm lub rhiav: hmoov av nyob rau hauv huab cua ntog ntawm cov duab ntub los ua cov ntsiab lus ntub dej tom qab salmness, rhuav tshem lub tiaj tiaj thiab xim sib xws.
Hluav taws xob zoo li qub: qhov hluav taws xob zoo li cas yog qhov yooj yim los nqus cov hmoov av thaum lub sijhawm ua haujlwm siab, thiab muaj ion cua bar yuav tsum tshem tawm cov hluav taws xob zoo li qub. Kev nruj kev hloov pauv: Tsis ruaj khov ntawm txoj kab ntau lawm yuav ua rau cov kab txaij ntau lawm yuav ua rau kom me ntsis, ua rau muaj cov txheej txheem tom qab.
