Paninga Galvanic. -Hiko Technology. -hiko

paninga Galvanic Ko te tikanga paninga o te whakarewa i roto i te tahi mau atu tikanga o te iahiko. kawea ana tēnei tukanga i roto i te whakamahi i ngā tikanga rumaki tikanga. I muri i tenei preconditioning e utaina papa iahiko ki te pati whakakikorua, i te mea he āheipuringa o te insulator ki tonu nei i te he kawehiko me ngā ki anodes (kia ratou wairewa me rewakore) me te pūrere mō te whakaū i te pāmahana me te whakaoho i te otinga.

utu tukatuka

Tuku o DC arata'i ki te meka e kua hipoki e te apa o te nika koura etahi matotoru ranei te kanohi paruru kitea, me te tūhono ki te wahi kawehiko o te poari. whakarite tūnga tika o nga anodes e te matotoru paninga ko āhua ōrite.

Kei te nuinga o te wā whakamana whakakikorua koura PCB te whakamahi i te tukanga e rua-taahiraa. Tuatahi, kei te rumakina ratou i roto i te pati, tono ai te te nika i-hiko. Ka whakamahia e tēnei te nui kiato nāianei, ai whakatakotoria he otinga waikawa o te apa nika te, he matotoru o 0.05-0.1 microns. Ka āta whakarite tēnei kaha adhesion o konukoreko me parahi, i te whakaiti i te porosity o te paninga me hoki ki te ārai, kătahi o parahi ki te apa koura. I muri i horoi, e te nuinga o te tuhinga neke i roto i te pati gilding te wahi i hanga te kaha e o apa koura ki te 0.5 m i te kawehiko.

Hiko me te whakapaipai

Ahakoa i roto i nga wa onamata reira ko he whakapaipai o te whakarewa toi. production Modern fokotuu e ki whakawhiwhi etahi āhuatanga ngā o te whakarewa maimoatanga mata galvanic kia whakamahia. Ka taea te whiwhi coatings tiaki o te konganuku rangatira i roto i ngā rerenga o konganuku i te brines raro i te mana o te nāianei hiko. Ki enei coatings he taea hoki ki te rawa he wa roa mau tonu te tae, me te mau umeraa o te whakapaipai. e kore ratou ārai anake pouri o nga hua, engari kua hoki he pānga oro pai. Hei tauira, whakakikoruatia ki te koura te hiriwa ranei ka taea ki te tiaki i te tae me te mau umeraa o te whakapaipai tūturu.

He maha ngā rerekētanga rerekē o tenei tukanga, ia o nei whai wāhi te whakamahi o te whakarewa:

- Konqueror;

- parahi whakakikorua;

- konutea;

- nika;

- he paninga tine-bismuth;

- hāora matū;

- passivation matū;

- anodizing;

- electropolishing.

chromium-whakakikorua

Tenei waiwai E ruia ana mata chromium maitai whakatakoto i runga i ngā wāhanga o te rauemi papanga i te kawehiko raro i te mahi o te nāianei hiko ranei. I roto i tenei take, e arotahi-hiko kei runga i te tiaki waikura te whakamahia mō te whakapaipai mo te whakanui ake i te tohu o te pakeke mata ranei. I whakakikoruatia i roto i te ahumahi, a taea te whakamahi mō te whakapaipai. I roto i tenei take, te whāinga matua o te tukanga -'oatu he umeraa mata konganuku o ataahua mīharo. Detail i mua i tono o chromium e ia kia orohia.

āhuatanga paninga

āhuatanga Hard whakakikorua Konqueror e ātete wera, kākahu tiketike resistance, wettability rawakore, te waku iti, me plasticity iti. I tua atu, e tango te mata taua āhuatanga rite te pūmautanga i roto i ngā o te waku, kaha ki te tu i te tohatoha utanga, me te te āhuatanga e pā ana ki te whakangaromanga ngāwari hāngai i te pikaunga ru. I whakakikoruatia chromium i roto i te puka o te waiu he iti o te pakeke, me te kakahu ātete, porosity iti. tiakina te mata te i te waikura i te tiaki i te ahua whakapaipai ātaahua.

Ko te whakamahi o te Konqueror ahumahi whakakikorua

Ko te whakaaro matua mō nei whakamahia te reira i roto i te ahumahi, tenei homai taipitopito o taua āhuatanga, pērā i nui haere mauroa, nui haere ātete ki te waikura, me te whakaiti i te waku. Na roto i tenei tukanga, riro te parahi kaha, e kore e te hau i raro ki te waikura, me te kore e ngaro i roto i te moana, me te wai noa, te waikawa hauota. paninga Galvanic o tenei momo arata'i ki te meka e riro nui anake te mea o te mea kua hiahiatia ki te hanga tukatuka atu nga kohakore mata, i roto i tenei take e kore pānga tīaroaro mai.

copperplating

Mā te coatings parahi e hāngai ana i roto i aua wā, ina te hiahiatia reira ki te whakapiki ake i te kawe ia hiko, me te ratou whakamahinga hei paparanga takawaenga i runga i te hua maitai i mua i te takoto te reira Konqueror, nika atu paninga ranei. Ko te kupu e taea ana ki te whakarato pai adhesion, ka whakarei ake i te kaha paruru. Parahi whakakikorua e kore te tikanga e whakamahia rite te motuhake whakapaipai ranei. Nā ki Ko te ahei o te ārai i te hanganga o korakora te whakarewa kaha, e taea te whakamahi i te hua i roto i te hinu, me te hau ahumahi.

Ko te whakamahi o te parahi whakakikorua

Kei te whakamahia i tēnei tukanga mō te paninga o te parahi i runga i te hua maitai te waea rino ranei. E mea pinepine, whakamahia tenei momo o te paninga te ki te tiaki i ngā wāhi o ngā hua parahi i sima, me tukatuka i te wa ano wāhi ki aua wāhi e e tūmanakohia ana ki te atu tukatuka mā te tapahi.

-Hiko paninga whakarewa i roto i tenei take maha whakamahia i roto i te hinu, me te hau ahumahi ki te ārai i te hanganga o muramura, i te mara hiko mo te waipara muri o coatings multilayer hangaia mo te tiaki me te whakapaipai, i roto i te hanga o te papa iahiko tā, ki te whakapai ake i te whakapiringa, me te tokomaha noa atu. whiwhi Mata tae i māwhero marama ki whero pouri. Ko te atarangi e kore te nuinga e te papa'iraa.

galvanizing

Ko tētahi o nga tikanga tino noa mo te tiaki o ngā hua whakarewa te galvanizing. Ko te tikanga te whakamahia ai mo te maimoatanga o te momo o te koranu waro rino ranei kōeke. -Hiko o tenei momo he rawaka tono mo te tiaki o ngā tuhinga i hanga o waea me toromoka. Whiwhi i roto i te taiao hou, te mata o te konutea tavini rite te pitoake, ko te kupu tērā hāora tauhohe, me te whakarewa matua i te fariiraa i tiaki i ngā āhuatanga taiao kino.

taea anake te whakamahi hiko o tenei momo i muri ki te tukatuka i te hua whakarewa i roto i te ara motuhake. Ki te rave i te reira, ūkui ratou i waikura, tauine, pūmārō meangiti tono hinu. A, no te te tukanga o galvanizing he oti, me waiho i raro i te hua ki te whakamārama, i.e. te maungärongo reira ki te otinga ngoikore o te waikawa hauota, aru i te passivation. Heoi e kore taea anake ki te whakapiki ake i te ātete o ngā hua piauau ki te āhuatanga kino, engari ano ki te hanga a ratou whakapaipai ake, e ko, ki te tāpiri whiti me te tetahi hue. -Hiko Hangarau i roto i tenei take tā te matotoru kahu konutea o 6 microns ki 1.5 mm.

nika-whakakikorua

Ka taea te rite tiaki o ngā hua whakarewa mā te whakamahi i te whānuitanga o ngā hangarau. Ko tētahi o te rongonui tino me noa i te kau, ko te sēniti. Ko e tika ana ki te āhuatanga matū o te konukoreko taua rongonui. Roaa te reira i te tohu tiketike o te ātete ki te te waikura i roto i te reo waiwai, ka ārai te ōkai nika pitihāoratanga atu o te whakarewa. I tua atu, nika painga Nireaha ki tai, waikawa me kawakore, ki te haunga o te waikawa hauota. Hei tauira, he matotoru whakakikorua 0,125 mm o tiaki ki te nuinga o hau ahumahi ki nui haere fakaaoao. He mea tino nui, me te kau taua: nika whakakikoruatia Nireaha ki tata katoa konganuku, kia taea te whakamahi i tēnei tikanga mō te tukatuka atu o ngā hua.

Ko te whakamahi o te nika he tika hoki te whānuitanga o ngā mahi whānui:

- te tiaki o ngā hua whakarewa;

- te whakamahi rite coatings whakapaipai;

- apa hanga i mua i-ki kia i raro ki te tukatuka atu;

- ora o nga wahi me hahi.

huru no te paninga e ātete kākahu tiketike, me te pakeke, me te tūtohutia hoki wāhanga e whakahaere i roto i ngā āhuatanga o te waku, rawa i roto i te ngaro o tetahi whakahinuhinu, whakamahia hoki te tiaki te waikura, me whakarato hoki solders pāmahana brazing kounga iti, whakaritea katoa i roto i ISO. Kua nui haere coatings Electroplated brittleness, Heoi e kore e tūtohu ki te whakaputa i flaring me te piko wahi haere tukanga nika whakakikorua. E tūtohutia ana ki te tono mō ngā taipitopito slozhnoprofilirovannyh. I muri i te tukanga maimoatanga wera i raro i ngā āhuatanga o 400 degrees paninga riro pakeke mōrahi.

Tin-bismuth

āhuatanga te paninga tine e ātete ki te mahi o pūhui-whanariki kei roto, e tūtohu ana hoki te wahi e kei i whakapā ki te rapa me kirihou. I roto i taea te huaina ona āhuatanga adhesion pai ki te turanga whakarewa, elasticity, kaha ki piko, tuhi, takahi, mumura, pēhia-pai, me te pupuri pai i roto i te āhua. ohaoha paninga tine korari iho pai ki te whakapiringa.

ngā kitenga

Whakakikorua whakapiki i nga āhuatanga o nga wahi conductive, hoatu ratou āhuatanga mātao hiko pai, me te tiaki ki te pānga o ngā matū rerekē. Ano, ka taea tenei tikanga ki te whiwhi mata pai he tirohanga hangarite, me te whaihanga i te paninga i tohu. He uaua ki te faarahi-hiko te faufaa i roto i te ahumahi hou rite te whanaketanga o te hangarau whakaaetia ki te hanga atu tino te tukanga.
