Kev kho deg kev lag luam

  Qhov saum npoo ntawm cov khoom plated yuav tsum tau kho kom zoo ua ntej plating. Degreasing thiab etching yog cov txheej txheem tseem ceeb, thiab qee qhov chaw hlau yuav tsum tau ntxuav kom huv si ua ntej kho. APG tau siv dav hauv cheeb tsam no.

Daim ntawv thov ntawm APG hauv kev ntxuav thiab degreasing ua ntej thiab tom qab hlau txheej thiab electroplating. Ib leeg-cov khoom siv surfactants muaj qhov seem seem tom qab ntxuav, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ua ntej txheej degreasing (cov roj pleev xim pleev xim tu tus nqi ≥98%). Yog li, txhawm rau txhim kho kev ua haujlwm ntawm cov tshuaj ntxuav hlau yuav tsum tau ua ke nrog Alkyl Polyglucoside. Cov nyhuv huv ntawm kev sib xyaw ua ke los ntawm APG 0814 thiab isomeric C13 polyoxyethylene ether yog ntau tshaj qhov sib xyaw los ntawm AEO-9 thiab isomeric C13 polyoxyethylene ether. Cov kws tshawb fawb los ntawm kev sim tshuaj ntsuam thiab kev sim orthogonal. Ua ke APG0814 nrog AEO-9, isomeric C13 polyoxyethylene ether, K12, thiab ntxiv inorganic bases, builders, thiab lwm yam. Tau txais cov hmoov tsis-phosphorus degreasing hmoov ntawm eco-phooj ywg, uas yuav tsum tau siv rau hauv kev kho hlau deg. Nws txoj kev ua tau zoo yog piv rau BH-11 (phosphorus degreasing zog) hauv khw. Cov kws tshawb fawb tau xaiv ntau yam biodegradable surfactants, xws li APG, AES, AEO-9 thiab tshuaj yej saponin (TS), thiab muab lawv los tsim ib qho dej hauv eco-phooj ywg detergency uas siv nyob rau hauv cov txheej txheem ua ntej ntawm cov hlau txheej. Kev tshawb fawb qhia tias APG C12 ~ 14 / AEO-9 thiab APG C8 ~ 10 / AEO-9 muaj kev sib koom ua ke. Tom qab kev sib xyaw ntawm APGC12 ~ 14 / AEO-9, nws tus nqi CMC raug txo rau 0.050 g / L, thiab tom qab sib xyaw ntawm APG C8 ~ 10 / AEO -9, nws tus nqi CMC raug txo rau 0.025g / L. qhov sib npaug ntawm huab hwm coj piv ntawm AE0-9 / APG C8 ~ 10 yog qhov zoo tshaj plaws formulation. Ib m (APG C8 ~ 10): m (AEO-9) = 1: 1, qhov concentration yog 3g / L, thiab ntxiv Na₂CO₃Raws li ib qho kev pabcuam rau kev sib xyaw hlau ntxuav tus neeg saib xyuas, kev tu tus nqi ntawm cov roj ntsha tuaj yeem ncav cuag 98.6%. Cov kws tshawb fawb kuj tau kawm txog kev tu lub peev xwm ntawm kev kho deg ntawm 45 # steel thiab HT300 grey cam khwb cia hlau, nrog siab clouded point thiab tu tus nqi ntawm APG0814, Peregal 0-10 thiab polyethylene glycol octyl phenyl ether nonionic surfactants thiab siab tu tus nqi ntawm anionic surfactants AOS.

kev tu tus nqi ntawm ib feem APG0814 yog ze rau AOS, me ntsis siab dua Peregal 0-10; CMC ntawm tus qub ob yog 5g / L qis dua tom kawg. Kev sib xyaw nrog plaub hom surfactants thiab ntxiv nrog cov tshuaj tiv thaiv xeb thiab lwm yam tshuaj ntxiv kom tau txais txiaj ntsig zoo thiab ib puag ncig tus phooj ywg chav dej-kub dej-raws li cov roj stain tu tus neeg saib xyuas, nrog kev tu kom zoo ntawm ntau dua 90%. Los ntawm ntau qhov kev sim orthogonal thiab cov kev sim ntsuas, cov kws tshawb fawb tau kawm txog cov txiaj ntsig ntawm ntau cov surfactants ntawm cov nyhuv degreasing. Qhov kev txiav txim tseem ceeb yog K12> APG> JFC> AE0-9, APG zoo dua AEO-9, thiab ua haujlwm tawm cov qauv zoo tshaj plaws yog K12 6%, AEO-9 2.5%, APG 2.5%, JFC 1%, ntxiv nrog rau lwm yam. tshuaj ntxiv. Cov roj tshem tawm ntawm cov roj stains ntawm cov hlau saum npoo yog tshaj 99%, eco-friendly thiab biodegradable. Cov kws tshawb fawb xaiv sodium lignosulfonate uas muaj zog detergency thiab biodegradability zoo sib xyaw nrog APGC8-10 thiab AEO-9, thiab kev sib koom ua ke yog qhov zoo.

Aluminium alloy ntxuav tus neeg saib xyuas. Cov kws tshawb fawb tau tsim cov tshuaj ntxuav tes tsis tu ncua rau txhuas-zinc alloys, sib txuas APG nrog ethoxy-propyloxy, C8 ~ C10 fatty cawv, fatty methyloxylate (CFMEE) thiab NPE 3% ~ 5% thiab cawv, additives, thiab lwm yam. Nws muaj cov haujlwm ntawm emulsification, dispersion thiab nkag mus, degreasing thiab dewaxing kom ua tiav qhov nruab nrab tu, tsis muaj corrosion lossis discoloration ntawm txhuas, zinc thiab alloy. Ib tug magnesium aluminium alloy ntxuav tus neeg sawv cev kuj tau tsim. Nws cov kev tshawb fawb qhia tau hais tias cov isomeric cawv ether thiab APG muaj ib tug synergistic nyhuv, tsim ib tug sib xyaw monomolecular adsorption txheej thiab tsim sib xyaw micelles nyob rau hauv lub puab ntawm kev daws, uas txhim kho lub binding muaj peev xwm ntawm surfactant thiab cov roj stain, ntawm no txhim kho lub peev xwm ntawm tu. tus neeg saib xyuas tu. Nrog rau qhov sib ntxiv ntawm APG, qhov nro ntawm qhov system maj mam txo. Thaum qhov sib ntxiv ntawm alkyl glycoside ntau dua 5%, qhov nro ntawm lub cev tsis hloov ntau, thiab qhov sib ntxiv ntawm alkyl glycoside yog 5% zoo dua. Cov mis mos yog: ethanolamine 10%, Iso-tridecyl cawv polyoxyethylene ether 8%, APG08105%, poov tshuaj pyrophosphate 5%, Tetrasodium hydroxy ethyldiphosphonate 5%, sodium molybdate 3%, propylene glycol methyl ether 7%, dej 57%,Tus neeg saib xyuas yog tsis muaj zog alkaline, nrog kev tu zoo, tsis tshua muaj corrosiveness rau magnesium aluminium alloy, yooj yim biodegradation, thiab ib puag ncig tus phooj ywg. Thaum lwm cov khoom tseem tsis tau hloov pauv, qhov kov lub kaum sab xis ntawm lub alloy nto nce ntawm 61 ° mus rau 91 ° tom qab isotridecanol polyoxyethylene ether hloov los ntawm APG0810, qhia tias cov nyhuv tu ntawm APG0810 zoo dua li qub.

Tsis tas li ntawd, APG muaj zoo dua corrosion inhibition zog rau txhuas alloys. Cov pab pawg hydroxyl nyob rau hauv cov qauv molecular ntawm APG yooj yim reacts nrog txhuas los ua tshuaj adsorption. Cov kws tshawb fawb tau kawm txog kev tiv thaiv corrosion ntawm ob peb feem ntau siv surfactants ntawm aluminium alloys. Nyob rau hauv acidic mob ntawm pH = 2, lub corrosion inhibition nyhuv ntawm APG (C12 ~ 14) thiab 6501 yog zoo dua. Nws qhov kev txiav txim ntawm corrosion inhibition nyhuv yog APG> 6501> AEO-9> LAS> AES, ntawm cov APG, 6501 zoo dua.

Tus nqi ntawm corrosion ntawm APG nyob rau saum npoo ntawm aluminium alloy tsuas yog 0.25 mg, tab sis lwm qhov peb cov kev daws teeb meem surfactant 6501, AEO-9 thiab LAS yog li 1 ~ 1.3 mg. nyob rau hauv alkaline mob ntawm Ph = 9, corrosion inhibition nyhuv ntawm APG thiab 6501 yog zoo dua. Dhau li ntawm qhov xwm txheej alkaline, APG nthuav qhia cov yam ntxwv ntawm cov nyhuv concentration.

Nyob rau hauv cov tshuaj NaOH ntawm 0.1mol / L, cov nyhuv ntawm corrosion inhibition yuav nce ib qib zuj zus nrog rau qhov nce ntawm concentration ntawm APG kom txog rau thaum mus txog rau lub ncov (1.2g / L), ces nrog nce concentration, cov nyhuv ntawm corrosion. inhibition yuav poob rov qab.

Lwm yam, xws li stainless hlau, ntawv ci tu. Cov kws tshawb fawb tau tsim cov tshuaj ntxuav tes rau stainless hlau oxide. Nws yog tsim los ntawm 30% ~ 50% cyclodextrin, 10% ~ 20% organic acid thiab 10% ~ 20% composite surfactant. Hais txog kev sib xyaw surfactant yog APG, sodium oleate, 6501 (1: 1: 1), uas muaj txiaj ntsig zoo ntawm kev ntxuav oxide. Nws muaj peev xwm los hloov tus neeg saib xyuas ntawm stainless hlau oxide txheej uas yog inorganic acid nyob rau tam sim no.

Ib tus neeg saib xyuas kev tu cov ntaub ntawv tseem tau tsim, uas yog tsim los ntawm APG thiab K12, sodium oleate, hydrochloric acid, ferric chloride, ethanol thiab dej ntshiab. Ntawm qhov tod tes, qhov sib ntxiv ntawm APG txo qhov nro ntawm cov ntawv ci, uas yuav pab tau rau cov tshuaj kom kis tau zoo dua ntawm cov ntawv ci thiab txhawb kev tshem tawm cov oxide txheej; Ntawm qhov tod tes, APG tuaj yeem tsim ua npuas dej ntawm qhov chaw ntawm cov tshuaj, uas txo cov kua qaub ntau. Txhawm rau txo qhov kev puas tsuaj rau tus neeg teb xov tooj thiab cov nyhuv corrosive ntawm cov cuab yeej, Meanwhile, cov tshuaj intermolecular adsorption tuaj yeem nqus cov organic ua haujlwm nyob rau hauv qee qhov chaw ntawm cov ntawv ci me me molecules los tsim cov kev mob zoo rau cov txheej txheem txuas ntxiv ntawm cov organic nplaum.
