Iphepha le-VCI lokuchasa ukwazisa:

Yintoni uthintelo lomhlwa kwisigaba somphunga?

Qala uqonde ukuba yintoni na umhlwa.

Umhlwa yinkqubo apho isinyithi ifuna ukubuyisela isimo sayo esizinzileyo se-oxide, yifom ye-mineral yokuqala.Ukuba mkhulu amandla asetyenzisiweyo ekusulungekiseni iminerali ethile ibe yintsimbi, kokukhona ukukhawuleza kwesantya sokubola kwesinyithi.I-Corrosion yinkqubo yokutshintsha kwe-electrochemical.Kukho inani elincinci leeyoni zombane kumphezulu wesinyithi ongalungiswanga, kwaye la masuntswana aya kuhamba ukusuka kwindawo ephezulu yamandla (i-anode) ukuya kwindawo yamandla aphantsi (i-cathode), ngaloo ndlela ivelisa umsinga, obizwa ngokuba yi-corrosion.

Iphepha lokulwa nesigaba somphunga licokiswa yinkqubo ekhethekileyo.Kwisithuba esivaliweyo, i-VCI equlethwe kwiphepha iqala ukuthoba kwaye iguqule igesi ye-antirust kubushushu obuqhelekileyo kunye noxinzelelo, olusasazeka kwaye lungene kumphezulu wento echasene ne-antirust kwaye iyibhengeze ukuba yenze umaleko oshinyeneyo wefilimu ekhuselayo enobunzima bemolekyuli enye. , ngaloo ndlela kuphunyezwa injongo yokungathembeki.

Iimpawu zephepha le-antirust lesigaba somphunga

1. Ukupakishwa okungenawo ioli, akukho kuthambisa, ukucocwa kunye neenkqubo zokucoca, ukonga iindleko zomsebenzi kunye nexesha.

2. Ukusebenza okuphezulu kwe-VCI kuqulethwe ngokufanayo kwiphepha le-antirust, elinokuthi lisebenzise ngokukhawuleza i-antirust effect emva kokupakishwa.

3. Ukuthintela ukugqwala okusebenzayo kunokufezekiswa nangaphandle kokudibanisa ngokuthe ngqo kwintsimbi, ngokukodwa kwiinqununu zetsimbi ezinobunzima obubonakalayo.

4. Inemisebenzi emibini yokuthintela umhlwa kunye nokupakishwa.

5. Xa kuthelekiswa nokupakishwa kwevacuum, ineendleko eziphantsi kwaye kulula ukuyisebenzisa.

6. Icocekile, ayinabungozi, ayinabungozi, inobuhlobo nokusingqongileyo kwaye ikhuselekile.

Iintsimbi ezisebenzayo: 

intsimbi yesinyithi, intsimbi yensimbi, isinyithi, ubhedu, ubhedu, ubhedu, isinyithi se-electroplated, i-zinc kunye ne-alloy, i-chromium kunye ne-alloy, i-cadmium kunye ne-alloy, i-nickel kunye ne-alloy, i-tin kunye ne-alloy, i-aluminium kunye ne-alloy kunye nezinye izinto zetsimbi kunye neemveliso.

Imiqathango yokusetyenziswa:

1. Iphepha le-antirust kufuneka linxibelelane ngokusondeleyo nomhlaba we-antirust into , kwaye akufanele kubekho umqobo phakathi kwabo.
2. Ngaphambi kokupakisha, ubuso bento echasene ne-antirust kufuneka buhlambuluke, bome kwaye bungabikho kwi-particle yangaphandle.
3.Ukuba umphezulu we-antirust into eqhelekileyo, indlela yokugubungela ngokupheleleyo ingaba
4. Nxiba iiglavu ezicocekileyo xa upakisha, kwaye ungachukumisi izinto ze-antirust ngezandla ezingenanto.
5. Ayinayo i-nitric acid, i-phosphoric acid, i-chromic acid, i-silicon kunye nezinye izinyithi ezinzima, kwaye ikhuselekile kwaye ayinakungcoliswa.

Ixesha lokuthintela umhlwa: 

1 ~ 3 iminyaka (sebenzisa ngokweemfuno kunye neenkcukacha)

Ukugcinwa nokugcinwa: Ipakethe etywiniweyo, igcinwe kwindawo epholileyo neyomileyo, kuthintelwe ukukhanya kwelanga, kuphephe ukudibana nemithombo yomlilo kunye nezinto ezidliwayo.Ubomi beshelufu ziinyanga ezili-12 ukususela kumhla wokuhanjiswa.

Inkqubo yokwenziwa kwemveliso:

Ipulp yevirgin yenziwe ngepulp yeplanga yekraft engaxutywanga, ibethwe, igayiwe, izaliswe (izinto), ikhutshelwe kumatshini wephepha, ize iqatywe ngerust remover (efana nesodium benzoate, sodium benzoate kunye nesodium nitrite umxube) kwiphepha lesiseko. ukudipha, ukuxukuxa okanye ukutyabeka ngeglu, emva koko yomiswe.

Iphepha le-anti rust linokuqina okuphezulu kunye nokuxhathisa ukusonga, kodwa alinayo nayiphi na into enokubangela umhlwa wesinyithi.Isetyenziselwa ukupakisha isinyithi sentsimbi, intsimbi, iimveliso zetsimbi, kunye nemibala emininzi yokupakishwa kwesinyithi kunye nemveliso yealloy yobhedu.Ukuba elinye icala lephepha lesiseko liqatywe ngeparafini wax okanye ipolyethylene resin, kwaye elinye icala liqatywe nge-vapor phase antirust inhibitor, isigaba somphunga sephepha le-antirust linokwenziwa.

Umahluko phakathi komphunga itekhnoloji ye-antirust kunye neteknoloji ye-antirust yemveli;

Ngenxa yempembelelo yemozulu, indawo, imathiriyeli yemveliso kunye nezinye izinto, izinto ezininzi zokusebenza ziya kuba nomhlwa kumphezulu wazo.Xa ukhetha iimveliso ezichasene nomhlwa, abahlobo abaninzi abazi ukuba banokukhetha njani iphepha lokuchasa umhlwa kunye nephepha lemveli lokuchasa umhlwa, ngoko ke makhe sazise umahluko phakathi komphunga-isigaba sokuchasa umhlwa kunye nephepha lemveli elichasayo.

Isigaba somphunga sephepha lokuchasa umhlwa yinto ekhethekileyo yokupakisha i-rust, esekelwe kwiphepha elikhethekileyo elingathathi hlangothi, elifakwe kwizinto ezikhethekileyo ezahlukeneyo-VCI, kwaye emva koluhlu lwe-post-processing.Phakathi kwezinto ezininzi kumzi mveliso wokupakisha, iphepha le-antirust lesigaba somphunga luhlobo lwemveliso yobuchwepheshe obuphezulu, kwaye itekhnoloji engundoqo ifakwe kwi-VCI.Itekhnoloji yeVCI yitekhnoloji ebanzi yokudibanisa i-organic synthesis, ikhemistri yomzimba, ukubola kunye nokukhuselwa, izinto zetsimbi, ukusetyenzwa kwephepha kunye nobuchwepheshe bepolymer.Iinkqubo ezahlukeneyo ze-VCI zinokumahluko omkhulu kukhuseleko, ukusebenza kakuhle, ukukhuselwa kwendalo kunye nokusebenziseka, ngoko ke zifakwe njengeemveliso ezineendlela ezahlukeneyo kunye nemisebenzi.

Iphepha lemveli lokuchasa umhlwa luhlobo loqhagamshelwano lwephepha lokuchasa umhlwa okanye umphunga wesigaba esincinci sephepha lokuchasa umhlwa elinecandelo elinye le-corrosion inhibitor.Isalathiso, isimo somphezulu, iipropathi ezibonakalayo kunye nefuthe lokuchasa umhlwa lephepha lemveli lokuchasa umhlwa azilunganga kakhulu.Nangona kunjalo, iphepha le-antirust langoku le-vapor-phase, elinokusebenza okuphezulu kunye ne-low vapor-phase corrosion inhibitor, ine-vapor-phase antirust kunye neempawu zokulwa ne-antirust, enesiphumo esihle, kwaye inokufikelela kwiifom ezahlukeneyo zesakhiwo ukuhlangabezana neemfuno ezahlukeneyo zamandla okupakisha.

Xa kuthelekiswa nephepha lemveli le-antirust, izibonelelo zephepha le-antirust lesigaba somphunga zezi zilandelayo:

1. Inokuthintela ngokufanelekileyo isinyithi kumswakama.

2. Ixesha le-anti rust yiminyaka eyi-1-2.

3. Ingaphinda isetyenziswe kwaye i-biodegradable.

4. Ayinatyhefu kwaye ayinabungozi.
