Lub ntsiab kev ntsuas ntawm coated cua txias aluminium ntawv ci

Coated aluminium ntawv ci yog tsim tom qab kev kho mob saum npoo ntawm lub hauv paus ntawm non-coated aluminium ntawv ci. Ntxiv nrog rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab qhov ntev geometric xav tau los ntawm cov lus hais saum toj no uas tsis yog-coated aluminium ntawv ci, nws yuav tsum muaj cov duab zoo thiab txheej txheej.

1. Cov duab ntawm aluminium ntawv ci

Ua ntej ntawm tag nrho cov, cov txheej txheem ntawm coated txhuas ntawv ci yuav tsum tau cov ntawv txhuas txhuas kom muaj ib tug zoo zoo, uas yog ib tug prerequisite rau zus tau tej cov coated txhuas ntawv ci. Chav ntsuas ntsuas phaj hom ntsuas yog I. Cov khoom siv txheej txheej dav dav yuav tsum muaj lub phaj zoo li ntawm 20-40I. Yog tias nws ntau dua li tus nqi no, ib qho kev nruj nruj yuav tsum tau ntxiv rau pem hauv ntej ntawm cov khoom siv txheej txheej. Feem ntau, txhuas sawb khiav txoj kev ntawm cov khoom siv txheej yog ntev, thiab muaj ntau cov txheej txheem ua thiab coj cov chais. Yog li ntawd, yog hais tias lub nro straightening system tsis tau nruab, ib zaug lub phaj zoo tsis zoo, nws yog ib qho yooj yim mus quav thaum lub sij hawm ua hauj lwm, uas ua rau tsis ua hauj lwm los tsim. Cov txheej txheem kev tsim cov tshuab cua txias kuj muaj cov kev xav tau siab dua ntawm cov duab ntawm aluminium ntawv ci. Feem ntau, cov kab ntau lawm ntawm cov ntawv sib pauv hluav taws xob xuas nrig ntaus siv lub tshuab nqus tsev nqus los hloov cov ntawv txhuas. Yog tias cov duab ntawm aluminium ntawv ci tsis zoo thiab qhov chaw tsis sib xws, lub tshuab nqus tsev nqus ntawm aluminium ntawv ci yuav tsis ua haujlwm ib txwm. Yog li ntawd, lub phaj zoo tsis yog tsuas yog ib qho tseem ceeb kev qhia ntawm coated aluminium ntawv ci, tab sis kuj tsis yog-coated aluminium ntawv ci.

2. Txheej kev ua haujlwm

Raws li tau hais ua ntej, muaj ntau hom coated aluminium foils rau cov khoom siv hluav taws xob. Cov coated aluminium foils siv nyob rau hauv kev ua lag luam feem ntau yog hydrophilic aluminium foils. Yog li ntawd, tsuas yog cov txheej txheem kev ua tau zoo ntawm hydrophilic aluminium foils yuav tau tham ntawm no.

3. Txheej thickness

Tsis muaj txoj cai nyuaj ntawm lub thickness ntawm txheej zaj duab xis rau ntawm qhov chaw ntawm aluminium ntawv ci, thiab nws feem ntau yog qis dua 3/1m. Vim tias tus nqi ntawm cov coatings feem ntau kim dua, qhov thinner lub txheej zaj duab xis thickness yog tswj raws li qhov ua tau raws li qhov yuav tsum tau ua, tus nqi qis dua. Lub thickness ntawm txheej ncaj qha cuam tshuam rau ntau yam kev ua tau zoo ntawm cov txheej txheem, yog li cov txheej txheej thickness ntawm cov ntawv txhuas yuav tsum tau ua kom zoo ib yam.

4. Txheej adhesion

Txheej adhesion yog qhov qhia tau tias ceev npaum li cas ntawm cov ntawv txhuas txhuas txuas rau nws cov txheej txheej. Yog tias txheej adhesion me me dhau lawm, cov yeeb yaj kiab txheej rau ntawm qhov chaw ntawm cov ntawv ci coated aluminium yuav yooj yim poob thaum lub sijhawm ua thiab siv ntxiv, uas yuav cuam tshuam rau qhov hnyav ntawm cov ntawv txhuas coated. Yog li ntawd, lub zog ntawm txheej adhesion, qhov zoo dua. Feem ntau, txheej adhesion tsuas tuaj yeem kuaj pom qhov zoo, thiab nws txoj kev tshawb pom tseem ceeb suav nrog kev kuaj kev puas tsuaj, khawb qhov ntsuas thiab cov txheej txheem cupping.

5. Hydrophilic zog

Tom qab cov ntawv ci hydrophilic aluminium siv rau lub sijhawm, kev ua haujlwm ntawm hydrophilic ntawm qhov chaw yuav cuam tshuam los ntawm ntau yam ib puag ncig. Yog li ntawd, qhov kev ua tau zoo ntawm hydrophilic feem ntau muab faib ua thawj qhov kev ua haujlwm ntawm hydrophilic thiab kev ua haujlwm ntawm hydrophilic tom qab kev ntsuas ib puag ncig. Qhov zoo ntawm hydrophilic kev ua tau zoo yog ntsuas los ntawm qhov loj ntawm lub kaum sab xis. Thawj qhov yuav tsum tau muaj hydrophilicity ntawm cov khoom siv dav dav yog a<100, and the hydrophilicity requirement after the environmental resistance test is a<250. The contact angle a can be measured by using a special contact angle measuring instrument; it can also be calculated from the area occupied by a certain volume of water droplets on the surface of the aluminum foil.

6. Corrosion kuj

Kev tiv thaiv corrosion feem ntau yog tshwm sim hauv peb yam: ib qho yog alkali tsis kam. Txij li cov roj lubricating ntawm qhov chaw ntawm lub tshav kub hloov pauv yuav tsum tau muab tshem tawm nrog cov tshuaj ntxuav alkaline, nws yuav tsum muaj cov txheej txheem ua haujlwm ntawm cov ntawv ci txhuas yuav tsum muaj qee qib ntawm alkali tsis kam. , Nws yog feem ntau yuav tsum tau tsau rau hauv 20 feem pua ​​​​NaOH tov rau 3 feeb yam tsis muaj foaming; Qhov thib ob yog ntsev tsuag corrosion kuj, feem ntau nyob rau hauv qhov kev ntsuas ntawm 35 oC, 3 feem pua ​​ntsev tsuag ib puag ncig yuav tsum tau 500 teev tsis muaj corrosion me ntsis. Cov ntsev tsuag tshuaj tiv thaiv corrosion yog ncaj qha cuam tshuam rau lub neej kev pab cuam ntawm lub tshav kub pauv fins. Nyob rau hauv cov ntug dej hiav txwv, vim muaj ntsev cov ntsiab lus nyob rau hauv cov huab cua, muaj siab yuav tsum tau rau cov ntsev tsuag corrosion kuj ntawm tshav kub pauv fins; Qhov thib peb yog cov cua sov thiab cov av noo tsis kam ua haujlwm, uas yog, kev tiv thaiv corrosion ntawm lub sijhawm ntev cia ntawm qee qhov kub thiab av noo. poj niam deev. Qhov kev ua tau zoo no kuj yog qhov taw qhia tseem ceeb los ntsuas cov huab cua tsis kam ntawm cov cua kub exchanger fins.
