Koj puas paub yuav ua li cas xaiv cov xim xim coils?

Koj puas paub xaiv li cas Xim-Coated Steel Coils?
Kev xaiv cov xim-coated steel coils tsuas yog hais txog kev xaiv cov cuab yeej siv kho tshuab, hom kev ua haujlwm sab nrauv thiab cov kev ua haujlwm ntawm pem hauv ntej thiab rov qab. Daim ntawv thov, ib puag ncig kev corrosion, kev pab cuam lub neej, kev ua kom ruaj khov, kev ua yeeb yam thiab kev tawm tsam yog qhov tseem ceeb los txiav txim siab thaum xaiv cov ntaub ntawv.
1. Xaiv cov tshuab khoom siv, txheej txheem hom thiab txheej hnyav
Cov khoom siv neeg kho tshuab tsuas yog xaiv raws li cov ntawv thov, kev ua qauv thiab kev ua haujlwm ntawm deformation. Piv txwv li, lub ru tsev panels ntawm cov tuam tsev feem ntau tsis thauj-kabmob, thiab deformation tsis nyuaj thaum lub sijhawm ua, yog li TDC51d feem ntau raug xaiv. Rau qhov chaw nrog cov qib kev sib txawv ntawm deformation, cov ntaub ntawv nrog kev tsim zoo xws li TDC52D thiab TDC53D yuav tsum tau xaiv. Rau cov khoom siv nrog cov qauv hnyav, tsim qauv qauv siv rau cov qauv siv, ts3500Gd, koj yuav tsum xaiv raws li cov yam ntxwv ntawm txhua txoj kev ua. Ib qho ntxiv, txij li cov kws kho tshuab ntawm substrate feem ntau yog siv los hloov cov cuab yeej siv cov khoom siv ntawm cov khoom siv cov khoom siv ntawm kev hloov pauv, qhov no yuav tsum tau sau tseg. Hom txheej (hom txheej) thiab qhov hnyav ntawm txheej yog xaiv tau raws li lub hom phiaj, ib puag ncig kev corrosion, ib puag ncig lub neej thiab kav ntev. Anti-corrosion yog ib qho ntawm cov khoom siv tseem ceeb ntawm cov nplooj ntawv xim, thiab qhov hnyav ntawm cov khoom siv feem cuam tshuam ntawm cov khoom siv xeb ntawm cov xim xim. Txij li thaum cov nplooj ntawv coated rau kev tsim kho feem ntau yog pom ncaj qha rau thaj chaw huab cua, substrates xws li zoo corrosion thiab tuab txheej tswj tau raug xaiv. Tsis tas li ntawd, cov corrosion resistance ntawm ntau hom ntawm cov txheej txheej kuj yog qhov sib txawv. Piv txwv li, nyob rau hauv tib co txheej tuab, corrosion tsis kam ntawm kub-dip txheej txhuas yog siab tshaj qhov ntawm kub-dip galvanized txheej. Tsis tas li ntawd, corrosion tsis kam feem ntau nce nrog nce ntawm cov xim hnyav, yog li cov nplooj ntawv tiv thaiv kab mob xim nrog kev ua haujlwm siab thiab / lossis nce qhov hnyav. Muaj ntau yam sib txawv ntawm kev txiav corrosion tsis kam ntawm kev txiav cov phiaj ntawm cov phiaj hlau nrog hom sib txawv, uas yuav tsum tau sau tseg. Ib qho ntxiv, kev pabcuam lub neej thiab cov kev pabcuam lub neej thiab cov kev pabcuam siv tau tseem yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej thaum xaiv cov ntaub ntawv. Yog tias lub neej pabcuam ntev thiab siab ntev yog yuav tsum tau, ib substrate nrog zoo corrosion tsis kam lossis hnyav txheej hnyav yuav tsum tau xaiv. Txij li thaum cov txheej ntawm galvanized cov ntaub ntawv muaj txog 55% aluminium (al), txhuas yog cov hlau bipolar uas tuaj yeem hnov ​​nrog ob qho kua qaub thiab alkali. Tom qab cement thiab dej yog sib xyaw rau hauv kev ua vaj tse xuab zeb, nws yog alkaline heev. Nyob rau hauv xws li ib puag ncig alkalinity, aluminium (al) (al) (Al) Yog li ntawd, galvanized dawb nplooj ntawv, suav nrog cov nplooj ntawv xim uas muaj cov nplooj ntawv galvanized, tsis haum rau kev sib cuag ntub nrog kev sib chwv ntub nrog cov cement ntub.
2. Xaiv rau ntawm cov txheej txheem hauv ntej
Kev xaiv ntawm cov txheej txheem ua haujlwm tseem ceeb yog hais txog cov txheej txheej, txheej xim tawv, pleev xim, txheej durability, thiab lwm yam kev xaiv ua tau zoo.
Hom tsho tiv no 1. Topcoat
Cov Topcoats muaj polyester, hloov kho polyester, muaj cov tshuaj fluoridene siab, R thiab Polyvinylidene fluoride. Muaj qee yam sib txawv hauv hardness, yooj yim / adhesion, corrosion tsis kam, e thiab lwm yam ntawm cov topcoats sib txawv. Polyester yog qhov feem ntau siv cov txheej ntawm tam sim no, nrog lub hardness dav dav, zoo ntawm cov txheej, thiab tus nqi nruab nrab. Lub durability, ci, thiab xim khaws cia ntawm silicon-hloov polyester tau txhim kho, tab sis qhov hloov tau ntawm txheej yog txo me ntsis. High-durable polyester muaj qhov zoo ntawm polyester thiab tau txhim kho nyob rau hauv lub durability, nrog tus nqi siab. Polyvinylidide muaj cov tshuaj fluinity muaj cov divability zoo tshaj plaws thiab kev siv hluav taws xob zoo ntawm cov txheej, cov xim muaj tsawg, thiab tus nqi kim heev. Txhawm rau cov ncauj lus kom ntxaws ntawm ntau cov tolycoats, thov saib rau cov ntaub ntawv cuam tshuam lossis sab laj cov kws txawj sib xws. Topcoats yog feem ntau tau txiav txim siab raws li cov txheej txheem, ib puag ncig corrosion, kev pabcuam lub neej, kav ntev, kev ua yeeb yam thiab degree ntawm deformation.
2. Primer
Cov primers suav nrog epoxy, polyester thiab polyurethane. Muaj qee yam sib txawv hauv cov nplaum, hloov tau yooj yim, corrosion tsis kam thiab lwm yam ntawm cov primers sib txawv. Epoxy muaj cov kev sib raug zoo nrog cov substrate thiab siab corrosion tsis kam, tab sis nws yooj yooj yog tsis zoo li lwm cov primers. Polyester tau ua kom zoo nrog lub substrate nrog lub substrate thiab zoo heev hloov, tab sis nws corrosion tsis kam yog tsis zoo li epoxy. Polyurethane yog qhov primer nrog cov kev ua tau zoo zoo. Cov ncauj lus kom ntxaws ntawm cov ntsuas kev ua tau zoo ntawm ntau tus primers tuaj yeem raug xa mus rau cov ntaub ntawv uas cuam tshuam lossis sab laj nrog cov kws txawj. Primers feem ntau yog txiav txim los ntawm cov tuam ntxhab raws li cov txheej txheem ntau lawm, siv, ib puag ncig corrosiveness, thiab txuam nrog kev sib raug zoo nrog cov topcoats.
3. Txheej tuab tuab
Lub corrosion tsis kam ntawm cov xim-coated daim hlau yog ze ze rau txheej txheej txheej txheej tuab. Feem ntau, corrosion kuj nce ntxiv nrog kev nce ntawm coating tuab. Qhov tsim nyog coating This yuav tsum txiav txim siab raws li ib puag ncig corroseness, kev pabcuam lub neej, thiab kav ntev.
4. Txheej xim sib txawv
Cov paib hlau-coated yuav muaj xim sib txawv thaum tsim khoom thiab siv. Txij li xim sib txawv tau cuam tshuam los ntawm ntau yam xws li ntau lawm, siv sijhawm, siv, lawv feem ntau yog kev sib ceg ntawm ob tog khoom thiab cov khoom siv thaum xaj.
5. Txheej ci ci
Lub teeb ci ci yog tsuas yog xaiv raws li lub hom phiaj thiab kev siv tus cwj pwm. Piv txwv li, cov paib hauv tsev rau kev tsim kho feem ntau xaiv nruab nrab thiab qis dua cov phiaj rau cov khoom siv hauv tsev feem ntau xaiv cov gloss.
6. Coating Hardness
Txheej hardness yog lub peev xwm ntawm txheej kom tiv taus cov neeg siv zog xws li khawb, sib txhuam, kev sib tsoo, thiab kev sib tsoo, thiab kev sib tsoo, thiab kev sib tsoo, thiab kev sib tsoo, thiab kev nyuaj siab. Nws yog ze ze rau cov kos tsis kam, hnav tsis kam, thiab indentation tiv thaiv ntawm cov xim-coated phaj. Nws yog tsuas yog xaiv raws lub hom phiaj, kev ua qauv, kev cia khoom thiab kev thauj mus los, thiab lwm yam.
7. TXHEEJ TXHEEM / ADHESIONS
Txheej txheej / Adhesion yog ze ze rau cov txheej txheem ntawm cov xim xim-coated phaj. Nws yog tsuas yog xaiv raws txoj kev ua, deformation degree, thiab lwm yam yog qhov loj me, xim me me lub zog muaj nqi yuav tsum tau xaiv.
8. Txheej tsis ruaj khov
Txheej xob durabilabe yog qhov ua tau zoo ntawm cov xim xim-coated daim hlau thaum siv, uas feem ntau yog ntsuas los ntawm lub sijhawm pabcuam kev pabcuam. Txheej Durability feem ntau cuam tshuam los ntawm cov khoom xws li txheej txheej, txheej tuab, thiab ib puag ncig corrosion. Qhov tseeb durability ntawm txheej tuaj yeem txiav txim siab los ntawm kev kuaj mob hauv atmospheric. Lub peev xwm ua kom muaj txiaj ntsig kuj tseem yuav raug tshuaj xyuas los ntawm kev ntsuas kev laus. Lub nruab nrab ntsev tsuag tshuaj tsuag tsuag tsuag yog ib qho yooj yim thiab feem ntau siv cov kev sim siab ua haujlwm sai thiab cov kev sim siab tseem ceeb. Ib qho ntxiv, cov ntoo co xim xim yuav siv tau rau hauv cov chaw tshwj xeeb xws li cov kua qaub los nag thiab av noo. Nyob rau lub sijhawm no, kev ntsuas khoom cuav khoom yuav tsum tau xaiv rau kev tshuaj xyuas. Nws yuav tsum raug sau tseg tias cov kev xeem cuav no feem ntau tsis tuaj yeem sim sim ua qhov chaw siv tiag tiag.
