Anaiia Aluminum me ko lakou mau lima: pehea, hana, i na mea maalea

Aluminum mea he kŘpa a pahee metala. Kekahi huahana mai ka mea e ho'ōla haalele i kona palapala ano, ma ka ili honua hemahema pohole, na oxides, ke huahana mae. Inā 'oe makemake e haawi kahiko mea i ka hou? Ueony, ia E e anaiia Aluminum. E hana i kēia, kekahi o na kēia mau kiʻina hana hiki ke hoʻohana:

• electropolishing;
• Nine Inch anaiia;
• Nani Loa etching.

Aluminum anaiia epekema: Nine Inch iaoia

Kēia enehana He environmentally aloha, noonoo ole, a 'ano ola. He mea hiki ke hoʻomaopopo, me kaʻakika-hoʻopale kila, a e lilo i kumu o ke anaiia bata. Inā o ka buke o ka hana, kŘpa a uuku, he mea hiki ke hana ipu hoʻoheheʻe i ka porcelain. Ua piha ka ipu me kaʻakika pāʻoihana:

• sulfuric;
• nitric;
• Phosphoric.

Products ua kuu iho la i loko o ka wela pāʻoihana, ka mahana e ka ÷ 90 a hiki i 120 ° C, o ka hope loa cia, e hilinaʻi ma luna o nā papa o ka Aluminum. I hooleiiaʻi mawaho Aluminum haku mele 'ana pono ia i loko o 30 kekona a minuke, oe a hana i kahi o 6 manawa. Ma waena o ka holoi māhele, a me kā lākou nele i mau lulu.

chemically anaiia Aluminum mea maikaʻi ka wā hoʻohana i ka pahu kaʻapuni māmā holo. Ma hope o ka pau ana o na manipulations ma luna o ka honua, e leka uila i ke keleawe pepa kini. It E e wehe 'ia ma ka holoiʻia ia ma lalo o ka wai e kahe me ka haʻahaʻa ana wela. Kēia i hanaʻia i loko o ka hei ai lakou. Ma ka pili ke kahua o ka huina hoonui hoʻokō '30 pakeneka nitricʻakika.

Additional koi ma luna o ka hana

Aluminum anaiia hiki ke hoʻokōʻia e kona'ākilikai pāʻoihana:

• trisodium posapahate;
• paʻakai nitrate;
• caustic soda;
• paʻakai nitrate.

Lākou wela pono e oi aku i hoohalikeia me kaʻakika iaoia, ke kali nei 120-140 ° C. Products pono ke ku imua o kahi o 5-20 kekona. Ka wā o kēiaʻano hana ua hoʻohana 'ia, i ke poho e e like i ka Aluminum o ma kahi o 8 microns ka huina, ahu iho kona mānoanoa.

Ka hoʻohana o electro-

Aluminum anaiia hiki ke hana ia ma kekahi alanui. Pela ka mea, Ua hiki e loaa ka lā'ī a me Kaulu, a me ka, i ka hoʻomaʻemaʻe mea o kiʻekiʻe e like ai. Electrolytes no ia mau hana i loko o ka hapanui hihia noho sulfuric a me ka phosphoricʻakika, ka mea'ē aʻe eiiiiiaiou e hilinaʻi ma luna o ka mea.

Electrolytes ke loaʻa iā gloss ma hope paʻaʻana. No ka mea kaʻina mahana e e haʻahaʻa ma mua i loko o ka luna hihia, ka mahana palena mea like i 60 me 90 ° C.

Anaiia pono e lawe mai no 5 minuke, oiai ka he nuʻa i e like no 10-50 A / dm². Kaʻina hana no ka anaiia cathodes komo ai i ka hoʻohana 'ana o ke kēpau, akā, ma laila nō nā oka a i hoomakaukau ai no ka pono o kuhiliʻole kila. Anaiia pono ai ka hana o ka duralumin ka wehe, e like me ka electrolyte auau me ka polyethylene, kēpau a PTFE aaioee. Oe Pono e hoomakaukau i kona'ākilikai electrolyte, ka mea i emi pipiʻi.

Ma ke kaʻina kiko'î e loli i ka haku mele 'ana o ka electrolyte, mahana kali i ĸokoĸa ana nä pane mai ka 40 a hiki i 95 ° C me ka pili ana i ka waiū, e mau mai ka 3 a hiki i 6 minuke, akā, i ka he nuʻa ma ka anode mea he kali no 3-20 A / dm². E koho cathodes, nikala mea ia e makemake ko.

Features Nani Loa etching

Aluminum anaiia hana i e Nani Loa. Kēiaʻano hana lawelawe 'ana me ka subspecies o electropolishing. Aluminum oka a i etched e anodes? Eia phosphorus-chromium electrolyte. Ma ka ili o ka 'atikala i hana mea pōaka kumu hoʻolike a i ka palapala o ke kumu a me ka hau. Ma ka anode koʻokoʻo kau mai i nā lāliʻi, a lailaʻoe e hoʻomaka i ka iapaau ana. Manipulation e halihaliia oia iwaho ma ke anakahi uila o 25-30 V. By ka hopena anakahi uila e pii ai i ka 35-40 V, ka anodic he nuʻa mea like i ka palena o ka 8-12 A / dm², oiai o ka mahana, e oko a mai ka 50 a hiki i 80 ° C.

Kahi o 20 minuke ma hope hoikeia unuhi. Inā ke anakahi uila, e hoomaka i ka ala o ka 'elele, ua hiki ke kuhi ana o ka kaʻina ka piha. Ma hope iho o ka pau ana o ka manipulation huahana e holoi, pono maloo, ua lawe mai ia anodizing ma luna o lākou. Aluminum Ua laila, make iho la ke aloha HW.

Aniani Aluminum hiki ke loaa ma kekahi papa hana alohilohi a me anodic etching, i ua kapaia iskritom. A hiki i keia huahana ma mua, a ma hope o ka kaʻina ua hoolilo e hoʻa'ā i lapaʻau i ka kūikawā noaia. Hiki nō ke hoʻohana i ka anodic etching "Snowball", a leie aku oe e hana i kekahi matteʻilikai sparkling.

He aha ke ala i ka maikaʻi hoʻohana ma ka hale

Ke kāpili ma luna no ka anaiia o kekahi o ka loa pinepine ia na mea paahana ma ka hale no ka anaiia Aluminum. O ke kumu ho i ka mea i ka Nine Inch mele o kekahi virulence, ka mea, ua pilikia ke kanaka ola. Anaiia hiki ke hoʻohana:

• sandpaper;
• scrubbing brushes;
• lacquer;
• lole popopo;
• ka hoʻomaʻemaʻe nā huahana no ke 'ano o ka waiʻona.

koho sandpaper mea nui ka wā,ʻaʻole i ka overdo ia i ka palaoa, no ka mea, i ole ia ka mea makemake i ke haalele scratches. No ka hoʻoikaika 'ana i ka Wear ia'ku a me ka mea maikaʻi, e hoʻohana i ka gloss lacquer.

Hiʻona o electrochemical anaiia

Electrochemical anaiia o Aluminum eaaaony no ka hoʻokō 'ana i ka laua hana ma ka Nine Inch a me ka pou ololi. E like me ka 'ike loea hou o ia i ka papa hana lawelawe' ana i kekahi hapa o ka anode'ūholo uila, ka mea, ua pili i ka maikaʻi DC lako kumu. Workpiece me ka kuu iho la i kaʻikena iā ia pono e bapetizoia ma ka? Aieeeua a ua piha i electrolyte. Ke kūlana o ka lua o ka'ūholo uila i hooleiiaʻi mawaho keleawe cathodes.

E ho ohana i ka anaiia mīkini

Machine no ka anaiia mea he kūpono mea, e hai aku i ka Aluminum o ka palapala gloss. Hiki nō ke hoʻohana i ka buff i ka 1000, a ua huakaʻi o i ka wai. Huahuakai a lole pono e pili ana i ka hoʻokō 'wai hapa. Eia hookomoia anaiia mīkini 1400 Hope no minuke. A hiki aku ia i kaʻehu ana, e hoopuehu aku a puni 1 m.

Aluminum 'ilikai e e pii kai, i ka wai, e evaporate. Oe pono e hoʻomākaukau no ka mea i ka hoa kanaka, e e hana Aluminum "porridge". Nolaila, o kela mea keia minuke o ka mīkini E e pani, e holoiʻia ia i ka wili huila me ka pulu huahuakai ma lalo o ka wai kahe. No keia hopena, kekahi paahana hoʻohanaʻike mau bryzgalku.

"Porridge" E e ua holoiʻia e like me nā lāliʻi. Alohilohi mai, ina oe e aiiieieoaeuii ke hoʻohana i ikeia. Kēia kahua o kekahi o ka mea nui. Ka mea, e hilinaʻi mai ia 80% o ka hopena hope loa. I manao ai e ana 10 mm o ma kela aoao o ka waihona ipu kaiapili e e huakaʻi o, hoohainu i ka wai i kona bryzgalku. Detail ua huakaʻi o me ka pulu ka huahuakai. Ke kāpili ma luna Ua hoʻohana 'ia Polish i ka ino, kona noi e halihaliia oia iwaho ma ka workpiece, ma mua o ka hoa kanaka.

ka hopena

Aluminum anaiia me kona mau lima ke e keʻano o nā mea, akā, kekahi o ka loa ka hoʻokō mea he kāpili ma luna. Ia, aole ia e apo ia ammonia mea hoʻonui, a hiki mālie maemae mai scratches a me roughness ka'ikamu. Me keia 'ole ia mea hiki ke kū i ka palapala alohilohi. Ke aiiay, ahu iho e hookaawale ia oxidations helehelena no ka lōʻihi wā.
