Amakuru ya Tekinike uss Ikiganiro kuri Brazing Technology ya Aluminium Ubushyuhe

Ibisobanuro

Imirasire yiboneye ibisekuruza bitatu byiterambere, aribyo imirasire yumuringa, aluminiyumu yahimbwe na radiyo ya aluminiyumu.Kugeza ubu, radiyo ya aluminiyumu imaze guhinduka ibihe, kandi gushakisha aluminium ni uburyo bushya bwo guhuza inganda mu nganda zikora za radiyo ya aluminium.Iyi ngingo iraganira cyane cyane kumahame shingiro hamwe nuburyo rusange bwimikorere yiyi tekinoroji ya aluminium igaragara.

1. Ibyiza nibibi bya aluminium brazing

Gukata ni bumwe muburyo butatu bwo gusudira bwo gusudira fusion, gusudira igitutu, no gushakisha.Gukata aluminiyumu ikoresha kugurisha icyuma hamwe no gushonga munsi yicyuma cyo gusudira.Shyushya uwagurishije no gusudira kugeza munsi yubushyuhe bwo gushonga kwa weld no hejuru yubushyuhe bwo kugurisha.Nuburyo bwo gukoresha umugurisha wamazi kugirango atose ibyuma bya weldment, yuzuza urwego ruto rwurugingo kandi akurura mugenzi we hamwe na molekile yicyuma yicyuma fatizo kugirango agere kumigambi yo guhuza gusudira.

akarusho:

1) Mubihe bisanzwe, gusudira ntibizashonga mugihe cyo gushakisha;

2) Ibice byinshi cyangwa imiterere-yuburyo bwinshi hamwe nudusudo twiziritse dushobora gutondekwa icyarimwe;

3) Irashobora gukata ibice bito cyane kandi byoroshye, kandi irashobora no gutwika ibice bifite itandukaniro rinini mububyimbye no mubyimbye;

4) Ihuriro rifatanije ryibikoresho bimwe na bimwe birashobora gusenywa no kongera gushyirwaho.

ibitagenda neza:

Kurugero: 1) Imbaraga zihariye zo gufatira hamwe ziri munsi yubwa felding yo gusudira, bityo ingingo za lap zikoreshwa kenshi kugirango zongere ubushobozi bwo gutwara;

2) Ibisabwa kugirango urwego rwogusukura rwubuso bwubuso bwibikorwa bya brazing hamwe nubwiza bwinteko yibikorwa biri hejuru cyane.

2. Ihame n'inzira ya aluminiyumu

Ihame rya aluminium

Mubisanzwe, mugihe cyo gushakisha, habaho firime yuzuye ya okiside hejuru ya aluminiyumu na aluminiyumu, ibyo bikaba bibuza gutemba no gutembera kwagurishijwe.Kubwibyo, kugirango ugere kumurongo mwiza wo gusudira, iki gice cya firime ya oxyde igomba gusenywa mbere yo gusudira.Mugihe cyo gushakisha, iyo ubushyuhe bugeze ku bushyuhe bukenewe bwa flux, flux itangira gushonga, kandi amazi yashongeshejwe akwirakwira hejuru ya aluminiyumu kugirango ashongeshe firime ya oxyde nkuko ubushyuhe buzamuka cyane.Amavuta ya Ai-Si atangira gushonga, kandi atembera mu cyuho cyo gusudira binyuze mu mitsi ya capillary, gutose no kwaguka kugira ngo bihuze.

Nubwo amahame ya brazing ya radiatori ya aluminiyumu arasa cyane, arashobora kugabanwa mumashanyarazi, guhumeka ikirere na Nocolok.guswera ukurikije inzira yo gushakisha.Ibikurikira nimwe mubigereranya byihariye muribi bikorwa bitatu byo gushakisha.

Mubikorwa bitatu, Nocolok.brazing ninzira yibanze ya aluminium radiator yo gushakisha.Impamvu Nocolok.gushakisha noneho birashobora kuba igice cyingenzi cyibikorwa bya aluminiyumu yumurongo wa brazing biterwa ahanini nubwiza bwiza bwo gusudira bwibicuruzwa.Kandi ifite ibiranga gukoresha ingufu nke, umusaruro mwinshi, ingaruka nke kubidukikije, hamwe no kurwanya ruswa.Nuburyo bwiza bwo gushakisha.

Nocolok.Inzira ya Brazing

Isuku

Hariho isuku itandukanye yibice no guhanagura ingirangingo.Muri iki gihe, kugenzura ubushyuhe nubushuhe bwumukozi ushinzwe isuku no kugumana ubushyuhe nubushuhe bwumukozi ushinzwe isuku ku gaciro gakwiye nintambwe zingenzi mugusukura.Ubunararibonye bufatika bwerekana ko ubushyuhe bwo gukora isuku bwa 40 ° C kugeza kuri 55 ° C hamwe nubushakashatsi bwibikoresho bya 20% nindangagaciro nziza zo gusukura ibice bya radiyo ya aluminium..

Niba hari flux ihagije, birashoboka gutwika igihangano cyakazi utabanje gukora isuku, ariko isuku izavamo inzira ihuriweho, ishobora kugabanya ubwinshi bwamazi yakoreshejwe no kubona ibicuruzwa bisa neza.Isuku yakazi ikora nayo izagira ingaruka kumubare wa flux.

Koresha flux

Gutera flux hejuru yibice bya aluminium ninzira yingenzi muri Nocolok.Igikorwa cyo gushakisha, ubwiza bwa spray flux bizagira ingaruka kuburyo butaziguye.Kuberako hari firime ya oxyde hejuru ya aluminium.Filime ya oxyde kuri aluminiyumu izabuza ubushuhe bwo hejuru no gutembera kwa fibre yashongeshejwe.Filime ya oxyde igomba gukurwaho cyangwa gutoborwa kugirango ikorwe.

Uruhare rwa flux: 1) Gusenya firime ya oxyde hejuru ya aluminium;2) Guteza imbere kugurisha no gutembera neza kubagurisha;3) Irinde ubuso kutongera okiside mugihe cyo gushakisha.Nyuma yo gushakisha birangiye, flux izakora firime ikingira hamwe ifatanye cyane hejuru yigice cya aluminium.Uru rupapuro rwa firime ahanini ntiruhindura ingaruka kumikorere yibicuruzwa, ariko birashobora kuzamura cyane ubushobozi bwibice bya aluminiyumu yo kurwanya ruswa.

Ingano ya flux ifatanye: Mugihe cyo gushakisha, ingano ya flux ifatanye: muri rusange 5g ya flux kuri metero kare;3g kuri metero kare nayo irasanzwe muri iki gihe.

Uburyo bwo kongeramo ibintu:

1) Hariho uburyo bwinshi butandukanye: gutera umuvuduko ukabije, gukaraba, gutera umuvuduko ukabije, kwibiza, gutera amashanyarazi;

2) Uburyo busanzwe bwo kongeramo flux muburyo bugenzurwa nikirere (c AB) ni ugutera gutera;

3) Imiterere yumubiri na chimique ya flux itera gutera amazi guhitamo bwa mbere;

4) Ku rwego rwisi, ukurikije imibare: 80% bakoresha spray itose, 15% bakoresha spray yumye, 5% bahitamo gutera spray cyangwa pre-coat;

Gutera ibishishwa biracyari uburyo busanzwe bwo gutembera mu nganda kandi butanga ibisubizo byiza cyane.

Kuma

Kugirango hamenyekane ubuziranenge bwibice bya brazing, urupapuro rwakazi rugomba gukama neza mbere yo kurigata kugirango ukureho ubuhehere.Ikintu gikomeye cyane mugukama ni ukugenzura ubushyuhe bwumye n'umuvuduko wa mesh;niba ubushyuhe buri hasi cyane cyangwa umuvuduko wa mesh urihuta cyane, intangiriro ntizakama, bikaviramo kugabanuka kwubwiza bwa brazing cyangwa desoldering.Ubushyuhe bwo gukama buri hagati ya 180 ° C na 250 ° C.

Brazing

Ubushyuhe bwa buri karere mugice cyo gushakisha, umuvuduko wa net hamwe nikirere cy itanura ryaka bigenzura ubwiza bwa brazing.Ubushyuhe bukabije hamwe nigihe cyo gushakisha bizagira ingaruka itaziguye kumiterere yibicuruzwa.Hatitawe ku kuba ubushyuhe buri hejuru cyane cyangwa buri hasi cyane, bizagira ingaruka mbi kubicuruzwa, nko kugabanya ubuzima bwa serivisi bwibicuruzwa, bikaviramo umuvuduko muke wuwagurishije, no kugabanya umunaniro wibicuruzwa;kubwibyo, kugenzura ubushyuhe nigihe cyo gushakisha ni urufunguzo rwibikorwa.

Ikirere kiri mu itanura ryaka ni ikintu cyingenzi kigira ingaruka ku gipimo cyo gusudira.Mu rwego rwo gukumira flux n'ibice bya aluminiyumu kuba okiside ihumeka ikirere, umuvuduko wa mesh ntugena gusa uburebure bwigihe cyo gushakisha, ahubwo unagena umusaruro ukorwa.Iyo ingano ya radiatori nini ari nini, kugirango ubone ubushyuhe buhagije kuri buri karere (pre-brazing zone, zone ashyushya na zone brazing) mugihe cyo gushakisha.Umuvuduko wurusobe ugomba kugenda gahoro kugirango ubushyuhe bwubuso bushobore kugera kubikorwa byiza.Ibinyuranye, iyo ingano yumurongo wa radiator ari nto, umuvuduko wurusobe ugomba kwihuta.

3. umwanzuro

Imirasire yiboneye ibisekuruza bitatu byiterambere, aribyo imirasire yumuringa, aluminiyumu yahimbwe na radiyo ya aluminiyumu.Kugeza ubu, imirasire ya aluminiyumu yahindutse ibaye ibihe, hamwe niterambere rihoraho niterambere ryikoranabuhanga, hamwe niterambere ryimodoka zoroheje.Imirasire ya aluminiyumu yakoreshejwe cyane kubera imbaraga zikomeye zo kwangirika, gutwara neza ubushyuhe hamwe nuburemere bworoshye.Hamwe nogukoresha kwinshi kumirasire ya aluminiyumu, ubushakashatsi ku ihame rya tekinoroji ya brazing nabwo buratera imbere mu koroshya no gutandukanya ibintu, kandi gushakisha ni tekinoroji igaragara yo gusudira mu nganda zikora za radiyo ya aluminium.Irashobora kugabanywamo ibyiciro bibiri: nta flux brazing na flux brazing.Gakondo ya flux brazing ikoresha chloride nka flux kugirango isenye firime ya oxyde hejuru ya aluminium.Ariko, gukoresha chloride flux bizana ibibazo bishobora kwangirika.Kugira ngo ibyo bishoboke, isosiyete ya aluminium yateje imbere ibintu bitangirika byitwa Nocolok.buryo.Nocolok.Brazing nicyerekezo cyiterambere kizaza, ariko Nocolok.Brazing nayo ifite aho igarukira.Kuva Nocolok.flux ntishobora gushonga mumazi, biragoye gutwikira flux kandi igomba gukama.Muri icyo gihe, fluoride flux irashobora kwitwara hamwe na magnesium, igabanya ikoreshwa ryibikoresho bya aluminium.Fluoride flux brazing ubushyuhe buri hejuru cyane.Nocolok.buryo buracyakenewe kunozwa.
