I. Cov ntsiab lus tseem ceeb thiab muaj nuj nqis ntawm cov txheej txheem txau

Txau, kuj hu uatxheej txheej, yog ib lub tshuab uas sib npaug siv cov xim rau cov khoom nto nrog cov cuab yeej tshaj lij. Haum rau cov yas, hlau, ceramics thiab lwm yam ntaub ntawv, nws lub hom phiaj kom ua tau raws li cov kev cai tseem ceeb xws li kub tsis kam, kev sib txhuam tsis kam, UV tiv thaiv thiab corrosion kuj. Rau cov tsom iav, tshuaj tsuag ua kom zoo nkauj thiab ua rau lub neej ua haujlwm ntev. Unsprayed thav duab yog nquag oxidation, khawb thiab muaj ib qho xim. Kev tshaj lij txau muab cov xim sib txawv (xws li, matte dub, gradient xiav, xim hlau nyiaj) kom tau raws li qhov xav tau ntawm kev zoo nkauj, thaum tsim cov yeeb yaj kiab tiv thaiv kom tiv thaiv kev sib txhuam txhua hnub, hws corrosion thiab sab nraum zoov UV hluav taws xob, ua kom cov iav zoo nkauj ntev ntev -.

Hauv kev lag luam tsom iav, nws tseem hu ua "xim txau" lossis "lacquer spraying" (transliterated los ntawm lus Askiv "lacquer", txhais tau tias cov kua roj vanish). Txawm tias muaj npe sib txawv, nws cov ntsiab lus tseem ceeb yog qhov sib xws: kev sib koom ua ke zoo nkauj thiab kev tiv thaiv los ntawm kev tswj cov xim adhesion thiab uniformity.

II. Core Spraying Equipment: Txhim kho los ntawm Phau Ntawv Qhia rau Kev Tswj Tus lej

Kev xaiv cov cuab yeej txau ncaj qha cuam tshuam rau txheej txheej zoo thiab kev ua haujlwm zoo. Kev lag luam muaj "phau ntawv- semi- tsis siv neeg- puv tsis siv neeg" gradient configuration kom tau raws li ntau haiv neeg thiab precision xav tau.

Cov tshuab phau ntawv yog rau me me -batch ntau lawm, qauv lossis cov thav duab nyuaj. Nrog rau cov qauv yooj yim ntawm rab phom txau, cua siab adjuster thiab workbench, cov neeg ua haujlwm kho lub kaum sab xis, nrug (15-25cm) thiab ceev. Lawv muab kev yooj yim rau kev tswj cov tuab tuab tab sis xav tau cov neeg ua haujlwm txawj kom tsis txhob muaj qhov tsis xws luag xws li cov tshuaj tsuag ploj thiab sagging, haum rau kev kho kom haum vim qhov ua haujlwm qis.

Semi- cov tshuab tsis siv neeg yog cov khoom siv loj, ntsuas qhov yooj yim thiab ua haujlwm tau zoo. Nrog ib tug rotatable workbench, thav ntawv yog tsau los ntawm fixtures. Cov neeg ua haujlwm siv ko taw hloov mus rau 360℃tsis sib xws, thiab cov phom rails txo cov neeg ua yuam kev. Lub kaw lus kaw nrog lub kaw lus tso tawm cov xim pos huab, tiv thaiv kev noj qab haus huv thiab ib puag ncig, haum rau nruab nrab -batch standardized ntau lawm.

Kev sib xyaw roj tsis siv neeg + cov khoom siv cov lej tswj tau qib siab rau cov khoom loj - teev ntau lawm. Nws nta precision thiab automation: lub mixing system ua raws li preset qauv kom tsis txhob muaj xim sib txawv, thaum tus lej tswj teeb tsa phom tsis siv neeg txau yam tsis muaj kev cuam tshuam los ntawm phau ntawv. Nws ua tiav ± 0.01mm thickness yuam kev, 5-8 npaug ntawm kev ua haujlwm siab dua li kev siv tshuab, thiab 85% + kev siv xim. Cov qauv high-end muaj kev tshawb nrhiav online los xyuas kom meej qhov kev tsim nyog.

III. Xim xaiv: Sib npaug ntawm cov qauv thiab cov nyhuv

Kev xaiv xim sib npaug zoo li, kev tiv thaiv thiab cov khoom siv hloov tau yooj yim, feem ntau muab faib ua cov toner -cov xim sib xyaw ua ke thiab cov xim tiav, txhua qhov zoo thiab qhov tsis zoo.

Toner - cov kuab tshuaj sib xyaw xim muaj ntau, muaj cov toner, cov kuab tshuaj (xws li, ethyl acetate) thiab cob. Kev sib xyaw ua ke kom tsis txhob muaj xim xim. Nws muaj cov qauv hloov tau yooj yim, tus nqi qis, haum rau feem ntau thav ntawv, thiab nws cov matte zoo nkauj tiv thaiv khawb, zoo tagnrho rau huab hwm coj- tsom iav khw.

Cov xim tiav yog npaj tau - rau - siv nrog cov xim xim siab. Nws cov viscosity siab yuav tsum muaj kev tswj xyuas meej kom tsis txhob muaj qhov tsis xws luag. Nws muaj xim saturation siab rau xim hlau / ci xim thiab zoo dua hnav tsis kam, tiv thaiv hlau thav duab los ntawm oxidation.

Xim yuav tsum phim cov ntaub ntawv: yas thav duab xim xav tau yooj yim kom tsis txhob tawg; hlau ncej xim yuav tsum muaj zog adhesion, feem ntau nrog ib tug primer los txhim kho kev sib raug zoo.

IV. Kev ziab kom qhuav: Kev tswj qhov kub thiab txias yog qhov tseem ceeb

Kev ziab yog qhov tseem ceeb rau txheej txheej, ua raws li "cov ntaub ntawv hloov kho thiab tswj qhov kub thiab txias" kom ntseeg tau tias qhov zoo.

Yas thav duab (TR90, PC) muaj cov cua sov tsis zoo, ziab ntawm 60-80℃rau 20-30 feeb. Overheating ua rau deformation; qhuav tsis txaus ua rau peeling. Cov cua kub qhov cub kom zoo ib yam, thiab cov qauv high-end siv segmented ziab kom tsis txhob blistering.

Hlau ncejyog kub-resistant, qhuav ntawm 120-180℃rau 30-45 feeb. Kev kub siab ntxiv dag zog rau cov yeeb yaj kiab tiv thaiv. Infrared ncu ua kom sib sib zog nqus curing, lub sij hawm luv dua thiab ua haujlwm ntau dua.

V. Kev Txhim Kho Ib puag ncig: Kev siv dej dav dav -Raws li xim

Tsav los ntawm ib puag ncig cov cai, dej- cov xim pleev xim los ua qhov tseem ceeb. Cov roj ib txwm siv - cov xim pleev xim emits VOCs, ua phem rau ib puag ncig thiab kev noj qab haus huv. Dej- cov xim pleev xim siv dej ua cov kuab tshuaj, uas yuav luag tsis muaj VOCs thiab tsis muaj ntxhiab tsw, daws teeb meem muaj kuab paug.

Nws tuav ib puag ncig tus phooj ywg thiab kev ua tau zoo, nrog cov xim hloov tau yooj yim sib xyaw thiab sib npaug tiv thaiv roj - xim xim. Cov kev ntsuam xyuas paub meej tias nws cov kav ntev, thiab cov khoom lag luam tseem ceeb tau txais nws, ua tiav cov txiaj ntsig kev lag luam thiab kev sib raug zoo.

VI. Kev soj ntsuam zoo: Ua kom tiav qhov kawg ntawm cov txheej txheem txau

Kev soj ntsuam nruj me ntsis yuav tsum tau ua ua ntej sib dhos, tsom mus rau cov tsos thiab kev ua tau zoo.

Kev tshuaj xyuas qhov tshwm sim: Kev kuaj pom thiab 10x lub iav tsom iav kom paub meej cov txheej txheem tsis muaj qhov tsis xws luag, xim sib xws (ΔE Tsawg dua lossis sib npaug rau 1.5) thiab tsis muaj xim sib xyaw rau ntawm qhov chaw zais.

Kev tshuaj xyuas kev ua tau zoo suav nrog kev sib txhuam, hws tiv thaiv, siab - kub thiab UV ntsuas. Tsuas yog cov khoom tsim nyog nkag mus rau cov txheej txheem tom ntej kom tau raws sijhawm ntev - siv cov kev xav tau.
