Daim ntawv VCI tiv thaiv xeb

VCI antirust daim ntawv qhia txog:

Kev tiv thaiv xeb theem vapor yog dab tsi?

Ua ntej tshaj, nkag siab tias xeb yog dab tsi.

Xeb yog ib qho txheej txheem uas hlau xav rov qab kho nws lub xeev oxide ruaj khov, uas yog nws cov qauv mineral qub. Lub zog ntau dua siv rau hauv kev ua kom cov mineral tshwj xeeb mus rau hauv ib qho hlau, qhov ceev ntawm kev xeb ntawm cov hlau. Kev xeb yog ib qho txheej txheem hloov pauv electrochemical. Muaj me me ntawm cov ions hluav taws xob nyob rau ntawm qhov chaw hlau tsis kho, thiab cov khoom me me no yuav txav mus los ntawm thaj chaw muaj zog siab (anode) mus rau thaj chaw muaj zog qis (cathode), yog li tsim cov hluav taws xob, uas hu ua xeb.

Daim ntawv vapor phase antirust yog ua kom zoo los ntawm cov txheej txheem tshwj xeeb. Hauv qhov chaw kaw, VCI uas muaj nyob hauv daim ntawv pib sublimate thiab volatilize cov roj antirust ntawm qhov kub thiab txias ib txwm muaj, uas diffuses thiab permeates rau ntawm qhov chaw ntawm cov khoom antirust thiab adsorbs nws los ua ib txheej tiv thaiv tuab nrog ib qho molecule thickness, yog li ua tiav lub hom phiaj ntawm antirust.

Cov yam ntxwv ntawm cov ntawv vapor-theem antirust

1. Cov ntim khoom tsis muaj roj, tsis muaj kev pleev xim, tshem roj thiab ntxuav cov txheej txheem, txuag cov nqi zog thiab lub sijhawm.

2. Kev ua tau zoo VCI yog uniformly muaj nyob rau hauv antirust daim ntawv, uas tuaj yeem ua rau sai sai antirust nyhuv tom qab ntim.

3. Kev tiv thaiv xeb zoo tuaj yeem ua tiav txawm tias tsis muaj kev sib cuag ncaj qha nrog hlau, tshwj xeeb tshaj yog rau cov hlau uas muaj tsos nyuaj.

4. Nws muaj ob txoj haujlwm ntawm kev tiv thaiv xeb thiab ntim khoom.

5. Piv nrog rau lub tshuab nqus tsev, nws pheej yig thiab yooj yim siv.

6. Huv si, tsis muaj teeb meem, tsis muaj tshuaj lom, zoo rau ib puag ncig thiab muaj kev nyab xeeb.

Cov hlau siv tau: 

hlau hlau, hlau alloy, hlau cam khwb cia, tooj liab, tooj dag, tooj dag, hlau electroplated, zinc thiab alloy, chromium thiab alloy, cadmium thiab alloy, nickel thiab alloy, tin thiab alloy, txhuas thiab alloy thiab lwm yam khoom siv hlau thiab khoom.

Cov kev ceev faj rau kev siv:

1. Daim ntawv tiv thaiv xeb yuav tsum nyob ze rau ntawm qhov chaw ntawm cov khoom tiv thaiv xeb, thiab yuav tsum tsis muaj kev cuam tshuam ntawm lawv.
2. Ua ntej ntim khoom, qhov chaw ntawm cov khoom siv tiv thaiv xeb yuav tsum huv, qhuav thiab tsis muaj cov khoom txawv teb chaws.
3. Yog tias qhov chaw ntawm cov khoom siv tiv thaiv xeb yog qhov tsis tu ncua, txoj kev npog tag nrho tuaj yeem ua tau
4. Hnav hnab looj tes huv si thaum ntim khoom, thiab tsis txhob kov cov khoom tiv thaiv xeb nrog tes liab qab.
5. Nws tsis muaj nitric acid, phosphoric acid, chromic acid, silicon thiab lwm yam hlau hnyav, thiab muaj kev nyab xeeb thiab tsis muaj kuab paug.

Lub sijhawm tiv thaiv xeb: 

1 ~ 3 xyoos (siv raws li qhov yuav tsum tau ua thiab cov lus qhia)

Kev Khaws Cia thiab Khaws Cia: Ntim khoom kaw, khaws cia rau qhov chaw txias thiab qhuav, tsis txhob muab tso rau hauv tshav ntuj ncaj qha, tsis txhob cia raug hluav taws thiab cov tshuaj corrosive. Lub txee lub neej yog 12 lub hlis txij li hnub xa khoom.

Cov txheej txheem tsim khoom:

Cov pulp tshiab yog ua los ntawm cov ntoo kraft tsis tau bleached, ntaus, sizing, sau (khoom siv), theej rau ntawm lub tshuab ntawv, thiab tom qab ntawd coated nrog xeb remover (xws li sodium benzoate, sodium benzoate thiab sodium nitrite sib tov) rau ntawm daim ntawv los ntawm kev dipping, txhuam lossis kua nplaum txheej, thiab tom qab ntawd ziab.

Daim ntawv tiv thaiv xeb muaj lub zog siab thiab tiv taus kev quav, tab sis kuj tsis muaj cov khoom siv uas yuav ua rau xeb hlau. Siv rau kev ntim hlau ferrous ntawm cov hlau cam khwb cia, hlau, cov khoom lag luam hlau galvanized, thiab ntau xim hlau ntim ntawm cov khoom tooj liab thiab tooj liab alloy. Yog tias ib sab ntawm daim ntawv hauv paus yog coated nrog paraffin wax lossis polyethylene resin, thiab lwm sab yog coated nrog vapor phase antirust inhibitor, vapor phase antirust daim ntawv tuaj yeem ua tau.

Qhov sib txawv ntawm cov txheej txheem tiv thaiv xeb theem vapor thiab cov txheej txheem tiv thaiv xeb ib txwm muaj;

Vim yog qhov cuam tshuam ntawm huab cua, qhov chaw nyob, cov ntaub ntawv khoom thiab lwm yam, ntau yam workpieces yuav muaj xeb ntawm lawv cov nplaim. Thaum xaiv cov khoom tiv thaiv xeb, ntau tus phooj ywg tsis paub yuav ua li cas xaiv cov ntawv vapor-phase anti-rust thiab cov ntawv tiv thaiv xeb ib txwm muaj, yog li cia peb qhia qhov txawv ntawm cov ntawv vapor-phase anti-rust thiab cov ntawv tiv thaiv xeb ib txwm muaj.

Daim ntawv vapor theem tiv thaiv xeb yog cov khoom ntim khoom tshwj xeeb tiv thaiv xeb, uas yog raws li daim ntawv tshwj xeeb tsis muaj zog, coated nrog ntau yam tshuaj tshwj xeeb-VCI, thiab tom qab ua tiav ntau yam. Ntawm ntau cov ntaub ntawv hauv kev lag luam ntim khoom, daim ntawv vapor-theem tiv thaiv xeb yog ib hom khoom siv high-tech, thiab nws cov thev naus laus zis tseem ceeb yog embodied hauv VCI. VCI thev naus laus zis yog cov thev naus laus zis ua tiav kev sib xyaw ua ke cov organic synthesis, lub cev chemistry, corrosion thiab kev tiv thaiv, cov ntaub ntawv hlau, kev ua ntawv thiab polymer thev naus laus zis. Cov txheej txheem VCI sib txawv muaj qhov sib txawv loj hauv kev nyab xeeb, kev ua haujlwm siab, kev tiv thaiv ib puag ncig thiab kev siv tau, yog li lawv tau embodied ua cov khoom nrog ntau yam duab thiab kev ua haujlwm.

Daim ntawv tiv thaiv xeb ib txwm muaj yog daim ntawv tiv thaiv xeb hom sib cuag lossis daim ntawv tiv thaiv xeb me ntsis uas muaj ib qho khoom tiv thaiv xeb. Cov ntsuas, qhov xwm txheej ntawm qhov chaw, cov khoom siv lub cev thiab cov nyhuv tiv thaiv xeb ntawm daim ntawv tiv thaiv xeb ib txwm tsis zoo heev. Txawm li cas los xij, daim ntawv tiv thaiv xeb vapor-phase tam sim no, nrog kev ua haujlwm siab thiab cov tshuaj tiv thaiv xeb vapor-phase qis, muaj cov khoom tiv thaiv xeb vapor-phase thiab kev sib cuag, nrog cov nyhuv zoo, thiab tuaj yeem ua tiav ntau yam qauv kom tau raws li cov kev xav tau sib txawv ntawm lub zog ntim khoom.

Piv nrog rau cov ntawv tiv thaiv xeb ib txwm muaj, qhov zoo ntawm cov ntawv vapor-theem antirust yog raws li nram no:

1. Nws tuaj yeem tiv thaiv cov hlau kom tsis txhob ntub.

2. Lub sijhawm tiv thaiv xeb yog 1-2 xyoos.

3. Nws tuaj yeem rov siv dua thiab biodegradable.

4. Tsis muaj tshuaj lom thiab tsis ua rau mob.
