  Iyo yepamusoro yezvigadzirwa zvakaputirwa inofanira kunyatsogadziriswa isati yaiswa.Degreasing uye etching ndiwo maitiro akakosha, uye mamwe masimbi emarata anoda kunyatsocheneswa asati arapwa.APG inoshandiswa zvakanyanya munzvimbo iyi.

Iko kushandiswa kweAPG mukuchenesa uye kudhiza isati yasvika uye mushure mekuputira simbi uye electroplating.Single-component surfactants ine zviri pachena zvakasara mushure mekuchenesa, izvo zvisingakwanisi kuzadzisa zvinodiwa zve pre-coating degreasing (artificial oil stain cleaning rate ≥98%). Naizvozvo, kuti uvandudze mashandiro esimbi yekuchenesa maajenti inoda kusanganisa neAlkyl Polyglucoside.Mhedzisiro yakachena yekubatanidza neAPG 0814 uye isomeric C13 polyoxyethylene ether yakawanda kupfuura iyo yekubatanidza neAEO-9 uye isomeric C13 polyoxyethylene ether. Vatsvagiri kuburikidza neyakatevedzana bvunzo yekrini uye orthogonal kuyedza.Yakasanganiswa APG0814 neAEO-9, isomeric C13 polyoxyethylene ether, K12, uye yakawedzera inorganic base, vavaki, nezvimwe. tora isiri-phosphorus degreasing poda ye eco-inoshamwaridzika, iyo inoshandiswa musimbi yekuchenesa kurapa.Kuita kwayo kwakazara kunofananidzwa neBH-11 (fosforasi degreasing simba) mumusika.Vatsvaguri vakasarudza akati wandei ane biodegradable surfactants, senge APG, AES, AEO-9 uye tii saponin (TS), uye akaasanganisa kuti agadzire eco-inoshamwaridzika mvura-based detergency iyo yaishandiswa mupre-kuita kwesimbi coating.Tsvakurudzo inoratidza izvozvo APG C12~14/AEO-9 uye APG C8~10/AEO-9 zvine synergistic mhedzisiro.Mushure mekusanganiswa kweAPGC12 ~ 14/AEO-9, kukosha kwayo kweCMC kunoderedzwa kusvika pa0.050 g/L, uye mushure mekusanganiswa kweAPG C8~10/AEO -9, kukosha kwayo kweCMC kunoderedzwa kusvika pa0.025g/L.iyo yakaenzana yehuwandu hwehuwandu hweAE0-9/APG C8~10 ndiyo yakanyanya kuumbwa.Per m(APG C8~10): m(AEO-9)=1:1, iyo concentration i3g/L, uye akawedzera Na₂CO₃semubatsiri kusanganisa simbi yekuchenesa mumiriri, mwero wekuchenesa wekusvibiswa kwemafuta ekugadzira unogona kusvika 98.6%. Vatsvakurudzi vakadzidzawo kugona kwekuchenesa kwekurapa kwepamusoro pa45# simbi uye HT300 grey cast iron, ine makore akakwirira uye chiyero chekuchenesa cheAPG0814,Peregal 0-10 uye polyethylene glycol octyl phenyl ether nonionic surfactants uye high cleaning rate yeanionic surfactants AOS.

chiyero chekuchenesa chechikamu chimwe chete APG0814 chiri pedyo neAOS, zvishoma kudarika Peregal 0-10;iyo CMC yevaviri vekare i5g/L yakaderera pane yekupedzisira.Kusanganiswa nemhando ina dzemasurfactants uye yakawedzerwa nerust inhibitors uye zvimwe zvinowedzera kuti uwane inoshanda uye ine hushamwari mukamuri-tembiricha yemvura-yakavakirwa mafuta ekuchenesa tsvina, iine kuchenesa kunodarika 90%.Kuburikidza nenhevedzano yeongororo yeorthogonal uye zviyedzo zvezvimiro, vaongorori vakaongorora mhedzisiro yevanoverengeka vano surfactants pane iyo degreasing maitiro.Iyo yakakosha kurongeka ndeye K12> APG> JFC> AE0-9, APG iri nani pane AEO-9, uye tsvaga yakanakisa formula ndeye K12 6%, AEO-9 2.5%, APG 2.5%, JFC 1%, yakawedzerwa nemamwe additives.Mwero wekubviswa kwemafuta emafuta emarara pasimbi pamusoro pe99%, eco-hushamwari uye biodegradable.Vatsvakurudzi vanosarudza sodium lignosulfonate ine detergency yakasimba uye yakanaka biodegradability kusanganisa ne APGC8-10 uye AEO-9, uye synergy yakanaka.

Aluminium alloy yekuchenesa mumiririri. Vatsvakurudzi vakagadzira imwe nzvimbo yekuchenesa aluminium-zinc alloys, ichibatanidza APG ne ethoxy-propyloxy, C8 ~ C10 mafuta ane doro, mafuta methyloxylate (CFMEE) uye NPE 3% ~ 5% uye doro, zvinowedzera, nezvimwewo. Iine mabasa e emulsification, kupararira uye kupinda, kuderedza uye kunyunguduka kuti uwane kucheneswa kusina kwazvakarerekera, pasina kuora kana kupera kwealuminium, zinc uye alloy.Iyo magnesium aluminium alloy yekuchenesa mumiriri yakagadziridzwa zvakare.Tsvagiridzo yaro inoratidza kuti iyo isomeric doro ether uye APG ine synergistic mhedzisiro, ichigadzira yakasanganiswa monomolecular adsorption layer uye kugadzira micelles yakasanganiswa mukati memushonga wemhinduro, izvo zvinovandudza kugona kwekusunga kweiyo surfactant uye tsvina yemafuta, nekudaro kuvandudza kugona kwekuchenesa. mumiririri wekuchenesa.Nekuwedzera kweAPG, kushushikana kwepasi peiyo system kunoderera zvishoma nezvishoma.Kana huwandu hwekuwedzera hwealkyl glycoside hunopfuura 5%, kushushikana kwepasi kweiyo system hakuchinji zvakanyanya, uye huwandu hwekuwedzera hwealkyl glycoside i5% zviri nani.Yakajairika fomula ndeiyi: ethanolamine 10%, Iso-tridecyl doro polyoxyethylene ether 8%, APG08105%, potassium pyrophosphate 5%; Tetrasodium hydroxy ethyldiphosphonate 5%, sodium molybdate 3%, propylene glycol methyl ether 7%, mvura 57%,iyo yekuchenesa mumiriri haina kusimba alkaline, ine yakanaka yekuchenesa mhedzisiro, yakaderera corrosiveness kune magnesium aluminium alloy, nyore biodegradation, uye nharaunda inoshamwaridzana.Kana zvimwe zvikamu zvikaramba zvisina kuchinjwa, iyo inobata angle ye alloy surface inowedzera kubva 61 ° kusvika 91 ° mushure mokunge isotridecanol polyoxyethylene ether inotsiviwa neAPG0810, zvichiratidza kuti kuchenesa kweAPG0810 kuri nani kupfuura yekare.

Mukuwedzera, APG ine zvirinani corrosion inhibition zvivakwa zvealuminium alloys.Iro hydroxyl boka mune molecular chimiro cheAPG chinopindirana nyore nealuminium kukonzera kemikari adsorption.Vatsvagiri vakadzidza nezve corrosion inhibition mhedzisiro yeakawanda anowanzo shandiswa surfactants pane aruminiyamu alloys.Pasi peiyo acidic mamiriro pH = 2, iyo corrosion inhibition mhedzisiro yeAPG (C12 ~ 14) uye 6501 iri nani.Kurongeka kwayo kwecorrosion inhibition effect ndeye APG> 6501> AEO-9> LAS> AES, pakati peiyo APG, 6501 iri nani.

Kuwanda kwekuora kweAPG pamusoro pealuminium alloy inongova 0.25 mg, asi mamwe matatu surfactant solutions 6501, AEO-9 uye LAS inenge 1 ~ 1.3 mg.pasi peiyo alkaline mamiriro ePh = 9, iyo corrosion inhibition mhedzisiro yeAPG uye 6501 iri nani.Kunze kwepasi peiyo alkaline mamiriro, iyo APG inopa chimiro chekuisa pfungwa.

Mumhinduro yeNaOH ye0.1mol/L, mhedzisiro yecorrosion inhibition ichawedzera nhanho nhanho inoperekedzwa nekuwedzera kweiyo APG kusvika pakusvika panhongonya (1.2g/L), zvino nekuwedzera kwekufungisisa, mhedzisiro yekuora. inhibition ichadzokera kumashure.

Zvimwe, zvakadai sesimbi isina tsvina, foil cleaning.Vatsvakurudzi vakagadzira detergency yestainless steel oxide.Inoumbwa ne30% ~ 50% cyclodextrin, 10% ~ 20% organic acid uye 10% ~ 20% composite surfactant.Anotaurwa anoumbwa surfactant ndeye APG, sodium oleate,6501(1:1:1), iyo ine zvirinani mhedzisiro yekuchenesa oxide.Iyo ine mukana wekutsiva iyo yekuchenesa mumiriri westainless simbi oxide layer iyo inonyanya inorganic acid parizvino.

Mushandi wekuchenesa wefoil surface yekuchenesa yakagadziridzwa zvakare, iyo inoumbwa neAPG neK12, sodium oleate, hydrochloric acid, ferric chloride, ethanol uye mvura yakachena.Kune rumwe rutivi, kuwedzerwa kweAPG kunoderedza kukanganiswa kwepamusoro kwepepi, iyo inobatsira kuti mhinduro ipararire zviri nani pamusoro pepamusoro uye kukurudzira kubviswa kwe oxide layer;kune rumwe rutivi, APG inogona kuumba furo pamusoro pemhinduro, iyo inoderedza zvikuru mhute yeasidhi.Kudzikisa kukuvadza kune mushandisi uye corrosive mhedzisiro pamidziyo, Zvichakadaro, iyo intermolecular kemikari adsorption inogona kushambadza iyo organic chiitiko mune dzimwe nzvimbo dzepamusoro pefoil mamorekuru madiki kuti agadzire mamwe mamiriro akanaka kune anotevera organic adhesive bonding process.
