Kev ceev faj rau txheej txheej ntau lawm

1. Kev saib xyuas yuav tsum tau them rau kev teeb tsa cov khoom pleev xim rau ntawm cov kab ntau lawm.Npaj lub hanger thiab txoj kev mounting cov khoom ntawm txheej txheej ntau lawm kab los ntawm kev sim dipping ua ntej kom paub tseeb tias lub workpiece nyob rau hauv qhov zoo tshaj plaws txoj hauj lwm thaum lub sij hawm dipping txheej txheem.Lub dav hlau loj tshaj plaws ntawm cov khoom yuav tsum tau coated yuav tsum ncaj, thiab lwm lub dav hlau yuav tsum nthuav tawm lub kaum sab xis ntawm 10 ° txog 40 ° nrog txoj kab rov tav, kom cov xim seem tuaj yeem ntws tawm ntawm cov xim pleev xim.

2. Thaum pleev xim rau, txhawm rau tiv thaiv cov kuab tshuaj los ntawm kev sib kis hauv lub rhiav thiab tiv thaiv cov plua plav los ntawm kev sib xyaw rau hauv lub tank xim, lub dipping tank yuav tsum tau khaws cia.

3. Tom qab cov khoom loj yog dipped thiab coated, lawv yuav tsum tau tos kom cov kuab tshuaj kom tag evaporate ua ntej xa lawv mus rau hauv chav tsev kom qhuav.

4. Nyob rau hauv cov txheej txheem ntawm painting, xyuam xim rau lub viscosity ntawm cov xim.Lub viscosity yuav tsum tau kuaj 1-2 zaug ib zaug.Yog hais tias lub viscosity nce 10%, nws yog tsim nyog los ntxiv hnyav nyob rau hauv lub sij hawm.Thaum ntxiv cov kuab tshuaj, lub dip txheej yuav tsum tau nres.Tom qab sib tov sib xyaw, xyuas cov viscosity ua ntej, thiab tom qab ntawd ua haujlwm ntxiv.

5. Lub thickness ntawm cov xim zaj duab xis txiav txim siab qhov nrawm nrawm ntawm cov khoom ntawm cov kab ntau lawm thiab cov viscosity ntawm cov tshuaj pleev xim.Tom qab tswj cov viscosity ntawm cov xim pleev xim, cov kab ntau lawm yuav tsum txiav txim siab qhov tsim nyog rau pem hauv ntej raws li qhov siab tshaj plaws ntawm cov xim zaj duab xis txog 30um, thiab raws li cov khoom sib txawv, kev sim.Ntawm tus nqi no, cov khoom yuav tsum tau coated yog tusyees advanced.Tus nqi ua ntej yog ceev, thiab cov xim pleev xim yog nyias;tus nqi ua ntej yog qeeb, thiab cov xim pleev xim yog tuab thiab tsis sib xws.

6. Thaum lub sij hawm dip txheej ua hauj lwm, tej zaum yuav muaj qhov sib txawv ntawm cov thickness ntawm cov xim zaj duab xis yog coated thiab lub hauv qab, tshwj xeeb tshaj yog tuab tsub zuj zuj nyob rau hauv qis ntug ntawm cov khoom coated.Txhawm rau txhim kho qhov zoo nkauj ntawm cov txheej, thaum dipping hauv cov khoom me me, cov txheej txheem txhuam yuav tsum tau siv los tshem tawm cov xim pleev xim ntxiv, los yog lub zog centrifugal lossis cov khoom siv electrostatic attraction tuaj yeem siv los tshem tawm cov xim tee.

7. Thaum dipping cov ntoo, xyuam xim rau lub sij hawm tsis ntev heev kom tsis txhob ntoo nqus cov xim ntau dhau, ua rau qeeb ziab thiab khib nyiab.

8. Txhim kho cov khoom cua kom tsis txhob muaj kuab paug vapor puas tsuaj;ua tib zoo saib xyuas cov txheej txheem ntawm kev tiv thaiv hluav taws thiab tsis tu ncua xyuas cov txheej txheem ntau lawm.
