Cov menyuam txheej tau dhau los ua txoj hauv kev nyiam siv cov txheej txheem ntawm aluminium coils vim nws cov txiaj ntsig thiab kev ua tau zoo.Nrog rau qhov kev thov ntau ntxiv rau cov khoom lag luam zoo thiab ruaj khov coated aluminium, cov menyuam txheej tau dhau los ua cov txheej txheem tseem ceeb hauv kev lag luam txhuas.Txawm li cas los xij, txhawm rau ua tiav cov txiaj ntsig xav tau, nws yog ib qho tseem ceeb kom nkag siab txog cov kev xav tau tshwj xeeb rau cov menyuam txheej.Nyob rau hauv no blog, peb yuav delve rau hauv qhov tseem ceeb ntawm kev ua tau zoo uas cov menyuam txheej txheej txheej yuav tsum ua kom tiav, tsom rau viscosity thiab leveling zog, ceev curing, zoo nkauj nta, thiab huab cua tsis kam.
1. Tsim nyog viscosity thiab zoo leveling zog:
Cov txheej txheem txheej txheej txheej txheej yuav siv txoj siv ceev ceev, cov menyuam txheej txheej, kub kub ci, thiab cua txias ceev.Txhawm rau ua kom pom qhov zoo tshaj plaws, nws yog ib qho tseem ceeb rau cov menyuam txheej txheej kom siv cov xim txaus rau ntawm cov khoom siv txhuas.Yog li ntawd, cov menyuam txheej txheej txheej yuav tsum muaj qhov tsim nyog viscosity thiab zoo leveling zog.Cov txheej txheej viscosity yuav tsum tau ua tib zoo tsim los ua kom yooj yim daim ntawv thov thaum tuav nws lub peev xwm kom qib sib npaug ntawm cov txhuas.Ua kom tiav qhov zoo viscosity tshuav nyiaj li cas yog qhov tseem ceeb hauv kev tiv thaiv cov teeb meem xws li tsis sib xws txheej thickness, streaks, thiab txiv kab ntxwv tev los.
2. Ceev curing:
Vim yog qhov ceev ceev ntawm cov menyuam txheej cov kab ntau lawm, kev kho ceev ceev yog qhov tseem ceeb rau cov menyuam txheej txheej txheej.Tsis muaj kev txhawb nqa thiab txwv lub qhov cub ntev ntev, lub sij hawm muaj xim los kho tau txo qis.Cov xim siv rau hauv cov menyuam txheej yuav tsum tau tsim los kho nyob rau hauv lub sijhawm luv luv, zoo dua tsawg dua 60 vib nas this.Tsis tas li ntawd, cov txheej txheem kho yuav tsum khaws cov xim hauv qab ntawm qhov kub ntawm 260°C los tiv thaiv cov khoom los ntawm deformation los yog lwm yam kev cuam tshuam tsis zoo.Kev xaiv cov kuab tshuaj kom zoo yog qhov tsim nyog kom ua tiav kev kho sai yam tsis muaj kev cuam tshuam cov txheej txheem kev ncaj ncees, zam cov teeb meem xws li bubbling, pinholes, thiab tsis zoo leveling.
3. Kho kom zoo nkauj nta:
Dhau li ntawm kev ua haujlwm zoo, cov menyuam txheej txheej txheej yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom zoo nkauj.Polyester xim feem ntau txaus rau kev ua tiav qhov kev xav tau nrog ib daim ntawv thov.Txawm li cas los xij, thaum siv fluorocarbon txheej, primer thiab topcoat yog tsim nyog rau kev pom kev zoo nkauj.Cov primer yuav tsum muaj kev tiv thaiv corrosion zoo heev thiab adhesion rau ob qho tib si substrate thiab topcoat, thaum lub topcoat yuav tsum muaj qhov zoo nkaum lub zog thiab cov khoom zoo nkauj.Ib lub tsho tiv no ntawm primer ua raws li ib lub tsho tiv no ntawm topcoat tuaj yeem ua rau lub ntsej muag zoo nkauj uas ua tau raws li qhov xav tau ntawm kev zoo nkauj thiab kev ua haujlwm.
4. Huab cua tsis kam:
Cov menyuam txheej txheej txheej yuav tsum muaj cov huab cua tshwj xeeb, tshwj xeeb tshaj yog thaum siv rau cov khoom siv sab nraum zoov.PVDF fluorocarbon coatings feem ntau yog siv los muab kev ua tau zoo tiv thaiv yam xws li kav ntev, kua qaub nag, huab cua paug, corrosion, sawv stains, thiab pwm.Nyob ntawm qhov chaw tshwj xeeb, ob, peb, lossis plaub lub tsho ntawm PVDF txheej tuaj yeem siv tau.Qhov no ua kom muaj kev tiv thaiv ntev thiab kev ua haujlwm siab tshaj plaws, tso cai rau cov coated aluminium coil tuaj yeem tiv taus txawm tias qhov hnyav tshaj ib puag ncig.
Xaus:
Hauv kev xaus, kev ua tiav qhov tshwj xeeb ntawm cov menyuam txheej txheej rau aluminium coils yuav tsum tau ua tib zoo xav txog cov txheej txheem viscosity thiab qib qib, muaj peev xwm kho tau sai, kho kom zoo nkauj, thiab huab cua tsis kam.Los ntawm kev nkag siab thiab ua raws li cov kev xav tau ntawm kev ua tau zoo, cov tuam ntxhab tuaj yeem tsim cov khoom lag luam zoo coated aluminium uas ua tau raws li cov qauv xav tau ntawm ntau yam kev lag luam.Raws li qhov kev thov rau kev txhim khu kev qha thiab pom kev zoo nkauj aluminium coils txuas ntxiv mus, nws yog ib qho tseem ceeb rau kev xaiv qhov tseem ceeb thiab kev siv cov txheej txheej txheej txheej uas tuaj yeem ua tiav cov kev ua haujlwm tseem ceeb.
