1. Uru na adịghị ike nke aluminum brazing

Brazing bụ otu n'ime ụzọ ịgbado ọkụ atọ nke ngwakọta ịgbado ọkụ, ịgbado ọkụ, na brazing.Aluminom brazing na-eji ígwè eme ihe nwere ebe mgbaze dị ala karịa nke metal welded.Kpoo ihe na-ere ahịa na welded ruo mgbe ọ dị n'okpuru okpomọkụ na-agbaze nke weldment na n'elu okpomọkụ na-agbaze nke ihe na-ere ahịa.Ọ bụ usoro iji mmiri na-ere mmiri na-eme ka mmiri dị nchara nke welding, jupụta ihe dị mkpa nke nkwonkwo ahụ ma na-adọta ibe ha na ngwongwo ígwè nke isi metal iji nweta nzube nke ijikọta weldment.

uru:

1) N'okpuru ọnọdụ nkịtị, weldment agaghị agbaze n'oge brazing;

2) Otutu akụkụ ma ọ bụ multi-layer Ọdịdị na akwu weld nwere ike brazed n'otu oge;

3) Ọ nwere ike braze ihe dị gịrịgịrị ma dị gịrịgịrị, yana nwekwara ike mebie akụkụ nwere nnukwu ọdịiche dị na ọkpụrụkpụ na ọkpụrụkpụ;

4) The brazed nkwonkwo nke ụfọdụ kpọmkwem ihe nwere ike dissembled na brazed ọzọ.

adịghị ike:

Dịka ọmụmaatụ: 1) Ike a kapịrị ọnụ nke nkwonkwo brazing dị ala karịa nke njikọ welding, ya mere a na-ejikarị nkwonkwo ụkwụ na-eme ka ikike ibu;

2) Ihe ndị a chọrọ maka ogo nhicha nke nkwonkwo nkwonkwo nke brazing workpiece na àgwà mgbakọ nke workpiece dị oke elu.

2. Ụkpụrụ na usoro nke brazing aluminum

Ụkpụrụ nke brazing aluminum

Ọtụtụ mgbe, n'oge brazing, a na-enwe nnukwu ihe nkiri oxide n'elu aluminom na aluminom alloy, nke na-egbochi wet na eruba nke a wụrụ awụ.Ya mere, iji nweta ezigbo nkwonkwo brazing nke welding, a ghaghị ibibi oyi akwa nke ihe nkiri oxide tupu ịgbado ọkụ.N'oge a na-eme brazing, mgbe okpomọkụ rutere n'ọnọdụ okpomọkụ achọrọ nke flux, mmiri na-amalite ịgbaze, na mgbawa nke a wụrụ awụ na-agbasa n'elu aluminum iji gbazee ihe nkiri oxide ka okpomọkụ na-arị elu.Alloy Ai-Si na-amalite ịgbaze, ma na-asọba na oghere ahụ ka a na-agbado ya site na mmegharị capillary, mmiri na-agbasawanye iji mepụta njikọ.

Ọ bụ ezie na ụkpụrụ brazing nke aluminom radiators yiri nke ọma, enwere ike kewaa ha na vacuum brazing, air brazing na Nocolok.brazing dị ka usoro brazing si dị.Ndị a bụ ntụnyere ụfọdụ akọwapụtara nke usoro brazing atọ ndị a.

N'ime usoro atọ ahụ, Nocolok.brazing bụ isi usoro nke aluminum radiator brazing usoro.Ihe mere Nocolok.brazing nwere ike ugbu a bụrụ akụkụ bụ isi nke usoro ịgbado ọkụ nke aluminum radiator bụ n'ihi ịdị mma ịgbado ọkụ nke ngwaahịa a.Ma o nwere njirimara nke oriri ume dị ala, nrụpụta nrụpụta dị elu, obere mmetụta gburugburu ebe obibi, yana nguzogide corrosion siri ike.Ọ bụ ezigbo usoro brazing.

Enwere nhicha dị iche iche nke akụkụ na nhicha nke cores radiator.N'oge a, ịchịkwa okpomọkụ na itinye uche nke onye na-ehicha ihe na idebe okpomọkụ na ntinye nke onye na-ehicha ihe dị mma bụ isi ihe na-eme ka ọ dị ọcha.Ahụmahụ bara uru na-egosi na okpomọkụ ihicha nke 40 ° C ruo 55 Celsius C na ntinye nke onye na-ehicha ihe nke 20% bụ ụkpụrụ kachasị mma maka ihicha akụkụ radiator aluminum.(Nke a na-ezo aka na onye na-ahụ maka nchekwa gburugburu ebe obibi aluminom, uru pH: 10; ndị ọrụ nhicha nke ụdị dị iche iche ma ọ bụ ọkwa pH kwesịrị nkwenye tupu ejiri ya)

Ọ bụrụ na enwere mmiri zuru ezu, ọ ga-ekwe omume ịkwanye workpiece na-enweghị ihicha, ma ihicha ga-eme ka a na-ahazi nhazi usoro, nke nwere ike belata ọnụ ọgụgụ nke flux na-eji na-enweta ezigbo mma welded ngwaahịa.Ịdị ọcha nke workpiece ga-emetụtakwa ọnụọgụ nke mkpuchi flux.

Ịgbasa mmiri n'elu akụkụ aluminom bụ usoro dị mkpa na Nocolok.Usoro brazing, ịdị mma nke ịgba mmiri ga-emetụta ogo brazing ozugbo.N'ihi na enwere ihe nkiri oxide n'elu aluminom.Ihe nkiri oxide nke dị na aluminom ga-egbochi mmiri mmiri n'elu na ntinye nke eriri a wụrụ awụ.A ghaghị iwepụ ma ọ bụ dụpuo ihe nkiri oxide iji mepụta weld.

Ọrụ nke mgbanwe: 1) Mebie ihe nkiri oxide n'elu aluminom;2) Kwalite wetting na ire ụtọ eruba nke solder;3) Gbochie elu ka ọ ghara ịdịghachi oxidizing n'oge usoro brazing.Mgbe emechara brazing, flux ga-etolite ihe nkiri nchebe nke nwere nrapado siri ike n'elu akụkụ aluminom.Nke a oyi akwa nke film isi enweghị oghom mmetụta na arụmọrụ nke ngwaahịa, ma ọ nwere ike ukwuu welie ike nke aluminom akụkụ iguzogide mpụga corrosion.

Ọnụ ego a na-ejikọta: N'oge usoro brazing, ọnụọgụ nke agbakwunyere: n'ozuzu 5g nke flux kwa square mita;3g kwa square mita bụkwa ihe a na-ahụkarị n'oge a.

Usoro mgbakwunye Flux:

1) E nwere ọtụtụ ụzọ dị iche iche: ịgbasa obere nrụgide, ịchafụ, nrịbama dị elu, ntanye, ịgbasa electrostatic;

2) Usoro a na-ahụkarị nke ịgbakwunye flux na brazing ikuku na-achịkwa (c AB) bụ nkwusioru spraying;

3) Njirimara anụ ahụ na nke kemịkalụ nke flux na-eme ka mmiri spraying nhọrọ mbụ;

4) Na ọnụ ọgụgụ zuru ụwa ọnụ, dị ka ọnụ ọgụgụ: 80% na-eji mmiri na-agba mmiri, 15% na-eji mmiri akọrọ, 5% na-ahọrọ nke ọma ma ọ bụ uwe mkpuchi;

Ịfesa mmiri mmiri ka bụ usoro a na-ejikarị eme ihe na ụlọ ọrụ ma na-enye ezigbo nsonaazụ.

Iji hụ na ịdị mma nke akụkụ brazing, a ga-ehichapụrịrị workpiece n'ihu brazing iji wepụ mmiri mmiri na mkpuchi flux.Ihe kachasị mkpa na usoro ihicha bụ ịchịkwa okpomọkụ ihicha na ọsọ ntupu;Ọ bụrụ na ọnọdụ okpomọkụ dị oke ala ma ọ bụ ọsọ ntupu dị oke ngwa ngwa, isi ya agaghị akpọnwụ, na-ebute mbelata n'ịdị mma brazing ma ọ bụ ịtọhapụ ya.Okpomọkụ ihicha na-adịkarị n'etiti 180 ° C na 250 Celsius.

Na-agba ọsọ

Ọnọdụ okpomọkụ nke mpaghara ọ bụla na ngalaba brazing, ọsọ nke net na ikuku nke ọkụ brazing na-achịkwa àgwà brazing.Okpomọkụ brazing na oge brazing ga-enwe mmetụta ozugbo na ogo ngwaahịa ahụ.N'agbanyeghị ma okpomọkụ dị oke ma ọ bụ dị ala, ọ ga-enwe mmetụta na-adịghị mma na ngwaahịa ahụ, dị ka ibelata ndụ ọrụ nke ngwaahịa ahụ, na-eme ka mmiri na-adịghị mma nke onye na-ere ahịa, na-ebelata ike ọgwụgwụ nke ngwaahịa ahụ;ya mere, ịchịkwa okpomọkụ na oge brazing bụ isi ihe na-emepụta usoro mmepụta.

Igwe ikuku dị na ọkụ brazing bụ ihe dị mkpa na-emetụta ọnụego ịgbado ọkụ.Iji gbochie ntụgharị na akụkụ aluminom site na ikuku oxidized, ọsọ nke ntupu ọ bụghị naanị na-ekpebi ogologo oge brazing, kamakwa na-ekpebi nrụpụta ọrụ.Mgbe olu nke isi radiator buru ibu, iji nweta okpomọkụ zuru oke maka mpaghara ọ bụla (mpaghara tupu brazing, mpaghara ọkụ na mpaghara brazing) n'oge usoro brazing.Ọsọ nke netwọk kwesịrị iji nwayọọ nwayọọ ka okpomọkụ dị n'elu wee ruo uru usoro kachasị mma.N'ụzọ megidere nke ahụ, mgbe ụda olu nke radiator dị ntakịrị, ọsọ nke netwọk kwesịrị ịdị ngwa ngwa.
