Metal spraying: usoro, nkà na ụzụ, na ngwá

The ewu na n'ichepụta ndi a na-eji elu-ike plastik. Ha na-elu na omenala ike ihe ruru ya ala ibu, nnabata na njikwa na irè. Ma metal na-nọgidere na ọtụtụ ọrụ dị ka ndị kasị adaba na okwu nke ihe onwunwe n'ịgwa nke ike, isi na anwụ ngwa ngwa. N'otu oge ahụ ọ na-adịghị mgbe niile ziri ezi na-eji nke a siri ike Ọdịdị. Esiwanye spraying Usoro e ji mee ka ọla, nke na-enye ohere workpiece akụkụ endow Njirimara kacha adabara na okwu nke ọrụ alloy.

General ozi na metallization teknụzụ

N'etiti oge a ụzọ mgbe galvanic metallization n'elu mkpuchi na-etinyere, na nmikpu na gbazee. Ot technology na-enyekwa a agụụ sputtering nhazi nke nwere ya nhazi ọkwa dabere na-arụsi ọrụ ike media. Agbanyeghị, ọ bụla deposition nke ọla bụ imeso ndị isi ihe onwunwe iji nweta ndị a ma ọ bụ ndị ọzọ na-echebe àgwà. Nke a nwere ike ịbụ corrosion na-eguzogide ọgwụ oyi akwa guzobere, mgbake nke furu efu ma ọ bụ idozi owuwu arụmọrụ eyi.

N'ihi ya na-arụ ọrụ n'elu ya onwe ya bụ na ọtụtụ ikpe doro ikpo ọgwụgwọ. Tupu itinye na metal ahụ na-gbazee burners, inductors, ma ọ bụ site na ala-na-okpomọkụ plasma ikpughe. N'ihi ya njikere mkpụrụ na ezigbo physico-chemical àgwà, na nke ozokwa metal deposition bụ na e mere a ntụ ntụ ụdị. Ihe, dị ka isi ihe nwere ike na-ejere otu metal, iko, ụfọdụ plastik ma ọ bụ osisi na nkume.

Chemical chromium plating usoro

Dị ka ihe na-arụsi ọrụ ike akụrụngwa ka e si otú ahụ deposition ahu nagide chemical reagents. Classical mejupụtara mejupụtara chromous chloride, sodium, acetic acid na mmiri na sodium hydroxide. spraying usoro a rụrụ na okpomọkụ nke banyere 80 Celsius C. Ọrụ amalite na njikere nke ihe onwunwe. A, chrome-eji maka n'imeso metal na-ebupụta, karịsịa ígwè. Tupu ọrụ nke bụ isi mkpuchi ihe onwunwe bụ a ọla kọpa oyi akwa. Next mepụtara chemical chrome sandblaster, jikọọ na Compressor echichi. Mgbe mmezu nke usoro ngwaahịa-na-asa na ọcha na mmiri na Fikiere.

ire ọkụ ọgwụgwọ usoro

Ọ bụrụ na ndị gara aga technology na-enye ọma ọzụzụ bases, nke a ga-akwagide na mkpuchi, na nke a, uche pụrụ iche na-akwụ ụgwọ ndị metallization ahụ. Modern ire ọkụ spraying nwere ike rụrụ iji polima powder, waya ma ọ bụ a eriri ihe onwunwe. Nke a uka na-eduzi n'ime oku oxy-propane ma ọ bụ oxyacetylene ọwa, na nke-agbaze na Mbugharị na ndabere nke abịakọrọ ikuku na-sprayed. Ọzọkwa, ihe ndị mejupụtara cools na-etolite a njikere na-eji mkpuchi.

Iji a Usoro ihe nwere ike nweta corrosion-eguzogide ma na n'ibu ume. N'ọrụ ihe nwere ike a na-emeso aluminum, nickel, zinc, ígwè na ọla alloys. Akpan akpan, bụ ire ọkụ spraying na-eji aka arụmọrụ nke na eji biarin, mkpuchi coatings, eletriki akụkụ, na na. D. Ke adianade do, technology-eji na ime imewe na ụkpụrụ ụlọ aghụghọ na-enye ji achọ Njirimara.

Agụụ deposition usoro

Na nke a, ọ bụ a otu ụzọ, nke na-agụnye guzobe mkpa fim ke agụụ n'okpuru nduzi nke kpọmkwem uzuoku odide. The technology na-emejuputa atumatu na ụzọ dị iche iche, gụnyere site thermal mmetụta, evaporation electronic na laser ibé. Ọ na-eji agụụ deposition iji melite technical àgwà nke akụkụ, na ngwá na ngwaọrụ. Ka ihe atụ, a nhazi-enye ohere na-etolite pụrụ iche "na-arụ ọrụ" coatings nke nwere ike welie eletriki conductivity, egbochi ihe Njirimara, na-eyi ndị na-eguzogide na corrosion nchedo.

The technology ji kee na ji achọ coatings. Na nke a, na Usoro nwere ike ejikwara na arụmọrụ nke chọrọ ka elu kpọmkwem. Ka ihe atụ, agụụ deposition na-eji na imewe awa na ọlaedo, n'ihi na aesthetic ntem okpokolo agba na dị ka. D.

Ọtụtụ mgbe na-eji maka spraying igwe, onwem na a supersonic nozulu. -Eji a obere size electric okpomọkụ arụ ọrụ na abịakọrọ ikuku ọkọnọ. A atụmatụ nke na-adịbeghị anya nlereanya bụ ikike ịgbanwe okpomọkụ 600 Celsius C. Ruo mgbe na-adịbeghị anya, na ojiji nke ọkọlọtọ ngwaọrụ yiri ụkpụrụ nke ime ihe nke pneumatic egbe, gbagwojuru anya site eziokwu na ahụ nká na ngwá ọrụ na-ekekọta. The ngwá ọrụ ọgbara ọhụrụ, ekele nke a rụrụ metal deposition, na-eji ụkpụrụ nke ihe atomizer. Nke a pụtara na n'oge Itie nke na-arụ ọrụ gas ajụ ọkọnọ ọwa nke ugboelu eruba ike ọsọ na-abawanye dị ka ibelata nke ọjà. N'otu oge tụlee na static nsogbu.

Iji belata na-eri nke n'ichepụta arụmọrụ maka nchedo nke metal si mpụta mmetụta na-eji ukwuu pụrụ iche, ma na-erughị irè n'aka. N'otu oge ahụ ọ na-enyere ịzọpụta na metal plating, ego nke nke bụ nkezi nke 8-10 puku. Ete. maka nkọwa. Financial viability n'ihi na eziokwu na ndị dị otú coatings nwere ike inye multiple ọtọ àgwà. Dị ka ihe atụ, na-emeso ndị metal akụrụngwa nke ụlọ Ọdịdị, i nwere ike inwe atụmatụ dị ka Anti-corrosion, iguzogide mmetụta nke mmiri ozuzo, n'ibu nchebe. E nwekwara pụrụ iche dara mkpuchi na pụrụ isi chebe ndị akụkụ si ike ike chemical na thermal mmetụta.
