Ishishini lonyango lomphezulu

  Umphezulu weemveliso ezicandiweyo kufuneka unyangwe ngocoselelo phambi kokubekwa. Ukwehlisa igrisi kunye ne-etching ziinkqubo eziyimfuneko, kwaye ezinye iindawo zentsimbi kufuneka zicocwe kakuhle phambi konyango. I-APG isetyenziswa kakhulu kule ndawo.

Ukusetyenziswa kwe-APG ekucoceni kunye nokuhlanjululwa ngaphambi nangemva kokufakwa kwesinyithi kunye ne-electroplating. Ii-surfactants zecandelo elinye zinentsalela ecacileyo emva kokucoca, engakwaziyo ukukhawulelana neemfuno ze-pre-coating degreasing (inqanaba lokucoca i-oyile eyenziweyo ≥98%). Ngoko ke, ukuphucula ukusebenza kweentsimbi zokucoca kufuneka zidibanise ne-Alkyl Polyglucoside. Umphumo ococekileyo wokudibanisa nge-APG 0814 kunye ne-isomeric C13 i-polyoxyethylene ether ingaphezulu kwe-compounding yi-AEO-9 kunye ne-isomeric C13 polyoxyethylene ether. Abaphandi ngovavanyo loluhlu lwesikrini kunye novavanyo lwe-orthogonal. Idityaniswe i-APG0814 kunye ne-AEO-9, i-isomeric C13 polyoxyethylene ether, i-K12, kunye neziseko ezingaphiliyo, abakhi, njl. fumana i-non-phosphorus degreasing powder ye-eco-friendly, esetyenziswe kunyango lokucoca ubuso besinyithi. Ukusebenza kwayo okubanzi kuthelekiswa ne-BH-11 (i-phosphorus degreasing power) kwimarike. Abaphandi bakhethe ii-surfactants ezininzi ezinokonakala kakhulu, ezinje nge-APG, i-AES, i-AEO-9 kunye ne-tea saponin (TS), kwaye bazidibanisa ukuze baphuhlise isicoci esisekwe emanzini eco-friendly ebesisetyenziswa kwinkqubo yangaphambili yokwaleka ngesinyithi. Uphando lubonisa ukuba I-APG C12~14/AEO-9 kunye ne-APG C8~10/AEO-9 zineempembelelo ze-synergistic. Emva kokuhlanganiswa kwe-APGC12 ~ 14 / AEO-9, ixabiso layo le-CMC liyancitshiswa libe yi-0.050 g / L, kwaye emva kokuhlanganiswa kwe-APG C8 ~ 10 / AEO -9, ixabiso layo le-CMC liyancipha ukuya kwi-0.025g / L. umlinganiselo olinganayo wobunzima be-AE0-9/APG C8 ~ 10 yeyona ndlela yokuqulunqa. Ngokwem(APG C8~10): m(AEO-9)=1:1, ugxininiso yi 3g/L, kwaye yongezwe uNa₂CO₃njengento encedisayo kwi-ejenti yokucoca isinyithi, izinga lokucoca ukungcola kweoli eyenziweyo linokufikelela kwi-98.6%. Abaphandi baye bafunda ukukwazi ukucocwa konyango lomphezulu kwi-45# yentsimbi kunye ne-HT300 yentsimbi engwevu, enendawo ephezulu yamafu kunye nesantya sokucoca se-APG0814,Peregal 0-10 kunye ne-polyethylene glycol octyl phenyl ether surfactants nonionic kunye nesantya esiphezulu sokucoca i-anionic surfactants AOS.

izinga lokucocwa kwecandelo elilodwa le-APG0814 lisondele kwi-AOS, liphezulu kancinci kunePeregal 0-10; i-CMC yezimbini zangaphambili yi-5g / L engaphantsi kuneyokugqibela. Ukudibanisa kunye neentlobo ezine ze-surfactants kunye nezongezwayo kunye ne-rust inhibitors kunye nezinye izongezo zokufumana i-agent esebenzayo kunye neyokusingqongileyo-igumbi lobushushu obunobushushu obusekwe kwi-oyile yokucoca i-oyile, kunye nokucoca okungaphezulu kwe-90%. Ngokusebenzisa uthotho lweemvavanyo ze-orthogonal kunye novavanyo olunemiqathango, abaphandi bafunde isiphumo sabaninzi be-surfactants kwisiphumo sokuhla. Umyalelo obalulekileyo ngu-K12>APG>JFC>AE0-9, i-APG ingcono kune-AEO-9, kwaye sebenzisa eyona fomyula ingcono yi-K12 6%, AEO-9 2.5%, APG 2.5%, JFC 1%, idityaniswe nezinye izongezo. Izinga lokususwa kwe-oyile yamabala e-oyile kumphezulu wentsimbi ingaphezulu kwe-99%, i-eco-friendly kwaye iyabola. Abaphandi bakhetha i-sodium lignosulfonate kunye ne-detergency enamandla kunye ne-biodegradability enhle yokuxuba ne-APGC8-10 kunye ne-AEO-9, kunye ne-synergy ilungile.

I-aluminiyam yokucoca i-agent yokucoca. Abaphandi baye baphuhlisa i-agent engathathi hlangothi yokucoca i-aluminium-zinc alloys, edibanisa i-APG kunye ne-ethoxy-propyloxy, i-C8 ~ C10 utywala obunamafutha, i-fatty methyloxylate (CFMEE) kunye ne-NPE 3% ~ 5% kunye notywala, izongezo, njl. i-emulsification, i-dispersion and penetration, i-degreasing kunye ne-dewaxing ukufezekisa ukucocwa okungathathi hlangothi, akukho konakala okanye ukubola kwe-aluminium, i-zinc kunye ne-alloy. I-agent ye-magnesium aluminium yokucoca i-alloy iye yaphuhliswa. Uphando lwayo lubonisa ukuba i-ether yotywala ye-isomeri kunye ne-APG inefuthe le-synergistic, yenza umaleko we-adsorption we-monomolecular oxubeneyo kunye nokwenza i-micelles edibeneyo ngaphakathi kwesisombululo, esiphucula amandla okubopha i-surfactant kunye ne-oyile yebala, ngaloo ndlela iphucula amandla okucoca. iarhente yokucoca. Ngokongezwa kwe-APG, ukuxinana komphezulu wenkqubo kuncipha ngokuthe ngcembe. Xa inani elongezelelweyo le-alkyl glycoside lidlula i-5%, ukunyanzeliswa komphezulu wenkqubo akutshintshi kakhulu, kwaye inani elongezelelweyo le-alkyl glycoside li-5% ngokufanelekileyo. Ifomula eqhelekileyo yile: ethanolamine 10%, Iso-tridecyl alcohol polyoxyethylene ether 8%, APG08105%, potassium pyrophosphate 5%; Tetrasodium hydroxy ethyldiphosphonate 5%, sodium molybdate 3%, propylene glycol methyl ether 7%, amanzi 57%,i-agent yokucoca i-alkaline ebuthathaka, enefuthe elihle lokucoca, i-corrosiveness ephantsi kwi-magnesium aluminium alloy, i-biodegradation elula, kunye nokusingqongileyo. Xa amanye amacandelo ehlala engatshintshi, i-angle ye-touch angle ye-alloy surface iyanda ukusuka kwi-61 ° ukuya kwi-91 ° emva kokuba i-isotridecanol polyoxyethylene ether ithathelwe indawo yi-APG0810, ebonisa ukuba umphumo wokucoca we-APG0810 ungcono kuneyokuqala.

Ukongeza, i-APG ineepropathi ezingcono zokuthintela umhlwa kwiialloyi zealuminium. Iqela le-hydroxyl kwi-molecular structure ye-APG isabela ngokulula nge-aluminiyam ukuze ibangele i-adsorption yeekhemikhali. Abaphandi baye baphonononga iziphumo zokuthintela ukubola kwezinto ezininzi ezisetyenziswa ngokuqhelekileyo kwii-alloys ze-aluminium. Ngaphantsi kwemeko ye-acidic ye-pH = 2, i-corrosion inhibition effect ye-APG (C12 ~ 14) kunye ne-6501 ingcono. Umyalelo wayo we-corrosion inhibition effect yi-APG> 6501> AEO-9> LAS> AES, phakathi kwayo i-APG, i-6501 ingcono.

Ubungakanani be-corrosion ye-APG ebusweni be-aluminium alloy yi-0.25 mg kuphela, kodwa ezinye izixazululo ezintathu ze-surfactant 6501, i-AEO-9 kunye ne-LAS malunga ne-1 ~ 1.3 mg. phantsi kwemeko ye-alkaline ye-Ph = 9, i-corrosion inhibition effect ye-APG kunye ne-6501 ingcono. Ngaphandle kwemeko ye-alkaline, i-APG ibonakalisa uphawu lwesiphumo soxinaniso.

Kwisisombululo se-NaOH se-0.1mol / L, umphumo we-corrosion inhibition uya kwandisa inyathelo ngesinyathelo kunye nokunyuka koxinzelelo lwe-APG de ufikelele kwi-peak (1.2g / L), ngoko ke ngokunyuka koxinzelelo, umphumo we-corrosion isithintelo siya kubuya umva.

Abanye, njengensimbi engenasici, ukucocwa kwefoyile. Abaphandi baye benza isixhobo sokucoca i-stainless steel oxide. Iqulunqwe nge-30% ~ 50% ye-cyclodextrin, i-10% ~ 20% ye-asidi ye-organic kunye ne-10% ~ 20% ye-surfactant edibeneyo. I-surfactant edibeneyo ekhankanywe yi-APG, i-sodium oleate, i-6501 (1: 1: 1), enempembelelo engcono yokucoca i-oxide. Inamandla okutshintsha i-agent yokucoca i-stainless steel oxide layer eyona i-asidi ye-inorganic ngoku.

I-agent yokucoca yokucoca i-foil surface nayo iye yaphuhliswa, eyenziwa yi-APG kunye ne-K12, i-sodium oleate, i-hydrochloric acid, i-ferric chloride, i-ethanol kunye namanzi acocekileyo. Ngakolunye uhlangothi, ukongezwa kwe-APG kunciphisa ukunyanzeliswa komphezulu we-foil, okunceda ukuba isisombululo sisasazeke ngcono kwi-foil kunye nokukhuthaza ukukhutshwa kwe-oxide layer; kwelinye icala, i-APG inokwenza i-foam phezu kwesisombululo, esinciphisa kakhulu inkungu ye-asidi. Ukunciphisa umonakalo kumqhubi kunye nefuthe elibi kwisixhobo, Okwangoku, i-adsorption yekhemikhali ye-intermolecular ingabhengeza umsebenzi we-organic kwiindawo ezithile zomphezulu we-foil iimolekyuli ezincinci ukudala iimeko ezilungele ngakumbi inkqubo yokunamathela kwi-organic adhesive.
