ʻoihana lapaʻau ʻili

  Pono e hoʻomaʻamaʻa maikaʻi ʻia ka ʻili o nā huahana plated ma mua o ka plating. ʻO ka degreasing a me ka etching nā hana pono ʻole, a pono e hoʻomaʻemaʻe pono ʻia kekahi mau mea metala ma mua o ka mālama ʻana. Hoʻohana nui ʻia ka APG ma kēia wahi.

ʻO ka hoʻohana ʻana o APG i ka hoʻomaʻemaʻe a me ka degreasing ma mua a ma hope o ka hoʻopili metala a me ka electroplating. Loaʻa i nā surfactants ʻāpana hoʻokahi ke koena ma hope o ka hoʻomaʻemaʻe ʻana, ʻaʻole hiki ke hoʻokō i nā koi o ka degreasing pre-coating (artificial oil stain cleaning rate ≥98%). No laila, e hoʻomaikaʻi i ka hana o nā mea hoʻomaʻemaʻe metala pono e hui pū me Alkyl Polyglucoside. ʻOi aku ka hopena maʻemaʻe o ka hui ʻana e APG 0814 a me ka isomeric C13 polyoxyethylene ether ma mua o ka hoʻohui ʻana e AEO-9 a me ka isomeric C13 polyoxyethylene ether. ʻO nā mea noiʻi ma o ka hoʻāʻo ʻana o ka pale a me ka hoʻokolohua orthogonal. Hoʻohui ʻia ʻo APG0814 me AEO-9, isomeric C13 polyoxyethylene ether, K12, a hoʻohui i nā kumu inorganic, nā mea kūkulu hale, etc. loaʻa i ka pauka degreasing non-phosphorus o ka eco-friendly, i hoʻopili ʻia i ka hoʻomaʻemaʻe ʻana i ka ʻili metala. Hoʻohālikelike ʻia kāna hana holoʻokoʻa me BH-11 (kahi mana phosphorus degreasing) ma ka mākeke. Ua koho ka poʻe noiʻi i kekahi mau surfactant biodegradable loa, e like me APG, AES, AEO-9 a me tea saponin (TS), a hoʻohui iā lākou i mea e hoʻomohala ai i kahi mea hoʻomaʻemaʻe wai-pili i hoʻohana ʻia i ka hana mua o ka uhi metala. Hōʻike ka noiʻi i kēlā APG C12 ~ 14 / AEO-9 a me APG C8 ~ 10 / AEO-9 loaʻa nā hopena synergistic. Ma hope o ka hui ʻana o APGC12 ~ 14 / AEO-9, ua hoʻemi ʻia kāna waiwai CMC i 0.050 g / L, a ma hope o ka hui ʻana o APG C8 ~ 10 / AEO -9, ua hoʻemi ʻia kāna waiwai CMC i 0.025g/L. ʻo ka like o ka lakio nui o AE0-9 / APG C8 ~ 10 ka mea maikaʻi loa. No ka m(APG C8~10): m(AEO-9)=1:1, ʻo 3g/L ka hoʻonui ʻana, a hoʻohui ʻia ʻo Na₂CO₃ma ke ʻano he mea kōkua i ka hui ʻana i ka mea hoʻomaʻemaʻe metala, hiki i ka 98.6% ka hoʻomaʻemaʻe ʻana o ka pollution aila artificial. Ua aʻo pū nā mea noiʻi i ka hiki ke hoʻomaʻemaʻe i ka mālama ʻana i ka ʻili ma 45 # kila a me ka hao hina hina HT300, me ka helu kapuaʻi kiʻekiʻe a me ka helu hoʻomaʻemaʻe o APG0814, Peregal 0-10 a me ka polyethylene glycol octyl phenyl ether nonionic surfactants a me ka helu hoʻomaʻemaʻe kiʻekiʻe o ka anionic surfactants AOS.

ʻo ka hoʻomaʻemaʻe ʻana o ka mea hoʻokahi APG0814 kokoke i AOS, ʻoi aku ka kiʻekiʻe ma mua o Peregal 0-10; ʻO ka CMC o nā mea mua ʻelua he 5g/L haʻahaʻa ma mua o ka hope. Hoʻohui ʻia me nā ʻano surfactants ʻehā a hoʻohui ʻia me nā mea hoʻopaneʻe ʻōpala a me nā mea hoʻohui ʻē aʻe e loaʻa ai kahi mea hoʻomaʻemaʻe ʻoi aku ka maikaʻi a me ke kaiapuni ʻana i ka lumi hoʻomaʻemaʻe wai hoʻomaʻemaʻe wai, me ka hoʻomaʻemaʻe ʻoi aku ma mua o 90%. Ma o nā hoʻokolohua orthogonal a me nā hoʻokolohua kūlana, ua aʻo nā mea noiʻi i ka hopena o kekahi mau surfactants ma ka hopena degreasing. ʻO ke kauoha koʻikoʻi ʻo K12>APG>JFC>AE0-9, ʻoi aku ka maikaʻi o APG ma mua o AEO-9, a e hana i ke ʻano maikaʻi loa ʻo K12 6%, AEO-9 2.5%, APG 2.5%, JFC 1%, hoʻohui ʻia me nā mea ʻē aʻe. mea hoʻohui. ʻOi aku ka nui o ka 99% o ka hoʻoneʻe ʻana i ka aila o nā ʻaila ʻaila ma luna o 99%, eco-friendly a biodegradable. Ua koho nā mea noiʻi i ka sodium lignosulfonate me ka detergency ikaika a me ka biodegradability maikaʻi e hui pū me APGC8-10 a me AEO-9, a maikaʻi ka synergy.

Mea hoʻomaʻemaʻe alumini alumini. Ua hoʻomohala nā mea noiʻi i kahi mea hoʻomaʻemaʻe kūʻokoʻa no nā aluminika-zinc alloys, e hui pū ana i ka APG me ka ethoxy-propyloxy, C8 ~ C10 fatty alcohol, fatty methyloxylate (CFMEE) a me NPE 3% ~ 5% a me ka waiʻona, additives, etc. emulsification, dispersion a me ke komo ʻana, degreasing a me ka dewaxing e hoʻokō ai i ka hoʻomaʻemaʻe kūʻokoʻa, ʻaʻohe corrosion a discoloration paha o ka aluminika, zinc a me ka alloy. Ua kūkulu ʻia kekahi mea hoʻomaʻemaʻe alumini alumini magnesium. Hōʻike kāna noiʻi ʻana he hopena synergistic ka isomeric alcohol ether a me APG, e hana ana i kahi monomolecular adsorption layer a me ka hana ʻana i nā micelles i hui ʻia i loko o ka hopena, e hoʻomaikaʻi ai i ka hiki ke hoʻopaʻa ʻia o ka surfactant a me ka ʻaila ʻaila, e hoʻomaikaʻi ai i ka hiki ke hoʻomaʻemaʻe. ka mea hoomaemae. Me ka hoʻohui ʻana o APG, e emi mālie ka ʻili o ka ʻōnaehana. Ke ʻoi aku ka nui o ka alkyl glycoside ma mua o 5%, ʻaʻole loli nui ka ʻili o ka ʻōnaehana, a ʻoi aku ka maikaʻi o ka hoʻohui ʻana o ka alkyl glycoside he 5%. ʻO ke kumu maʻamau: ethanolamine 10%, Iso-tridecyl alcohol polyoxyethylene ether 8%, APG08105%, ʻO ka pāhana pyrophosphate 5%, Tetrasodium hydroxy ethyldiphosphonate 5%, sodium molybdate 3%, propylene glycol methyl ether 7%, wai 57 %,ʻO ka mea hoʻomaʻemaʻe he alkaline nāwaliwali, me ka hopena hoʻomaʻemaʻe maikaʻi, haʻahaʻa haʻahaʻa i ka magnesium alumini alumini, maʻalahi biodegradation, a me ke aloha kaiapuni. Ke hoʻololi ʻole ʻia nā mea ʻē aʻe, piʻi ka huina pā o ka ʻili alloy mai 61 ° a 91 ° ma hope o ka hoʻololi ʻana o ka isotridecanol polyoxyethylene ether e APG0810, e hōʻike ana i ka hopena hoʻomaʻemaʻe o APG0810 ʻoi aku ka maikaʻi ma mua o ka mua.

Eia kekahi, ʻoi aku ka maikaʻi o ka APG i nā waiwai inhibition corrosion no nā alumini alumini. ʻO ka hui hydroxyl i loko o ka molecular structure o APG e hana maʻalahi me ka alumini e hana i ka adsorption kemika. Ua aʻo ka poʻe noiʻi i nā hopena pale ʻino o kekahi mau surfactants maʻamau i hoʻohana ʻia ma nā alumini alumini. Ma lalo o ke kūlana acidic o pH = 2, ʻoi aku ka maikaʻi o ka hopena inhibition corrosion o APG (C12 ~ 14) a me 6501. ʻO kāna kauoha o ka hopena inhibition corrosion ʻo APG> 6501> AEO-9> LAS> AES, ma waena o APG, 6501 ʻoi aku ka maikaʻi.

ʻO ka nui o ka corrosion o APG ma ka ʻili o ke alumini alumini he 0.25 mg wale nō, akā ʻo nā mea ʻē aʻe ʻekolu surfactant solutions 6501, AEO-9 a me LAS ma kahi o 1 ~ 1.3 mg. ma lalo o ke kūlana alkaline o Ph=9, ʻoi aku ka maikaʻi o ka hopena inhibition corrosion o APG a me 6501. Ma waho aʻe o ke kūlana alkaline, ke hōʻike nei ka APG i ka hiʻohiʻona o ka hopena koʻikoʻi.

Ma ka hopena NaOH o 0.1mol / L, e hoʻonui ka hopena o ka corrosion inhibition i kēlā me kēia pae me ka piʻi ʻana o ka neʻe ʻana o APG a hiki i ka piko (1.2g / L), a laila me ka piʻi ʻana o ka ʻike, ka hopena o ka corrosion. e hāʻule i hope ka inhibition.

ʻO nā mea ʻē aʻe, e like me ke kila kila, hoʻomaʻemaʻe foil. Ua hoʻomohala ka poʻe noiʻi i kahi detergency no ke kila kila kila. Ua haku ia o 30% ~ 50% cyclodextrin, 10% ~ 20% organic waika a me 10% ~ 20% composite surfactant. ʻO ka surfactant composite i ʻōlelo ʻia ʻo APG, sodium oleate, 6501(1:1:1), ʻoi aku ka maikaʻi o ka hoʻomaʻemaʻe oxide. Loaʻa iā ia ka mea hiki ke hoʻololi i ka mea hoʻomaʻemaʻe o ke kila kila kila ʻokikene ka nui o ka waika inorganic i kēia manawa.

Ua hoʻomohala ʻia kahi mea hoʻomaʻemaʻe no ka hoʻomaʻemaʻe ʻana i ka foil, i haku ʻia me APG a me K12, sodium oleate, hydrochloric acid, ferric chloride, ethanol a me ka wai maʻemaʻe. Ma kekahi ʻaoʻao, ʻo ka hoʻohui ʻana o APG e hōʻemi i ka ʻili o ka ʻili o ka foil, he mea kōkua i ka hoʻonā e hoʻolaha maikaʻi ma luna o ka ʻili o ka foil a hoʻoikaika i ka wehe ʻana o ka papa oxide; ma ka ʻaoʻao ʻē aʻe, hiki i ka APG ke hana i ka huʻa ma ka ʻili o ka hopena, kahi e hoʻemi nui ai i ka noe waikawa. No ka ho'ēmiʻana i ka pōʻino i ka mea hoʻohana a me ka hopena corrosive i nā mea hana, I kēia manawa, hiki i ka intermolecular chemical adsorption ke adsorp i ka hana organik i kekahi mau wahi o ka ʻili o nā molekele liʻiliʻi o ka foil e hana i nā kūlana maikaʻi loa no ke kaʻina hana hoʻopili organik.
