1. Kubatsira uye kuipa kwealuminium brazing

Brazing ndiyo imwe yenzira nhatu dzekushongedza dzekusanganisa welding, pressure welding, uye brazing.Aluminium brazing inoshandisa simbi solder ine nzvimbo yakanyunguduka yakaderera pane iyo yeweldment simbi.Pisa solder uye weldment kusvika yave pasi pe tembiricha yekunyungudika ye weldment uye pamusoro pekunyungudika kweiyo solder.Inzira yekushandisa solder yemvura kunyorovesa simbi yeweldment, kuzadza musono wakatetepa wejoint uye kukwezva mumwe nemumwe nemamorekuru esimbi e base metal kuzadzisa chinangwa chekubatanidza weldment.

advantage :

1) Pasi pemamiriro akajairika, iyo weldment haizonyungudika panguva yebrazing;

2) Zvikamu zvakawanda kana akawanda-layer dhizaini uye nested weldments inogona kugadzirwa panguva imwe chete;

3) Inogona kubhuroka zvitete uye zvakatetepa zvikamu, uye zvakare inogona kusungira zvikamu zvine misiyano yakakura mukukora uye ukobvu;

4) Majoini akashongedzwa ezvimwe zvinhu chaiwo anogona kupatsanurwa uye kubvongodzwa zvakare.

kushomeka:

Semuyenzaniso: 1) Iyo chaiyo simba remajoini ekubhuroka yakaderera pane iyo yekubatanidza welding, saka majoini emakumbo anowanzoshandiswa kuwedzera simba rekutakura;

2) Izvo zvinodikanwa zvedhigirii rekuchenesa kweiyo yakabatana pamusoro peiyo brazing workpiece uye gungano remhando yeworkpiece yakakwirira kwazvo.

2. Nheyo uye nzira yealuminium brazing

Nheyo yealuminium brazing

Kazhinji, panguva yebrazing, pane dense oxide firimu pamusoro pealuminium uye aruminiyamu alloy, iyo inotadzisa kunyorova uye kuyerera kweakanyungudutswa solder.Naizvozvo, kuti uwane yakanaka brazing joint ye weldment, iyi layer ye oxide film inofanira kuparadzwa isati yatungirwa.Munguva yekupisa, kana tembiricha ichisvika painoda tembiricha yekuyerera, iyo inoyerera inotanga kunyunguduka, uye iyo yakanyungudutswa flux inopararira pamusoro pealuminium kuti iparadze iyo oxide firimu sezvo tembiricha ichiwedzera.Iyo Ai-Si alloy inotanga kunyunguduka, uye inoyerera ichienda kune gaka kuti isungirwe kuburikidza nekufamba kwecapillary, inonyorova uye inowedzera kuita mubatanidzwa.

Kunyangwe iyo misimboti yearuminiyamu radiators yakangofanana, inogona kukamurwa kuita vacuum brazing, air brazing uye Nocolok.brazing maererano nekugadzirisa.Izvi zvinotevera kumwe kufananidzwa kwakananga kweaya matatu maitiro ekubhurosa.

Pakati pematatu maitiro, Nocolok.brazing ndiyo yakakosha maitiro ealuminium radiator brazing process.Chikonzero nei Nocolok.brazing ikozvino inogona kuve yepakati chikamu chealuminium radiator brazing process inonyanya kukonzerwa nekunaka kwemhando yewelding yechigadzirwa ichi.Uye ine hunhu hwekushomeka kwesimba rekushandisa, yakakwira kugadzirwa kwesimba, diki mhedzisiro yemamiriro ekunze, uye yakasimba corrosion resistance.Iyo inzira yakanaka yekubhuroka.

Nocolok.Brazing Process

Kuchenesa

Kune kwakasiyana kucheneswa kwezvikamu uye kucheneswa kwema radiator cores.Panguva ino, kudzora tembiricha uye kusangana kwemugadziri wekuchenesa uye kuchengetedza tembiricha uye kusangana kwemugadziri wekuchenesa pane yakakosha kukosha ndiwo matanho akakosha mukuchenesa.Chiitiko chinoshanda chinoratidza kuti tembiricha yekuchenesa ye40 ° C kusvika 55 ° C uye kusangana kwekuchenesa mumiririri we20% ndiyo yakanakisa kukosha kwekuchenesa aluminium radiator zvikamu.(Apa zvinoreva aruminiyamu yekudzivirira yekuchenesa nharaunda, pH kukosha: 10; maejenti ekuchenesa emhando dzakasiyana kana mazinga epH anofanirwa kusimbiswa asati ashandiswa)

Kana paine flux yakakwana, zvinokwanisika kubhuroka basa pasina kuchenesa, asi kucheneswa kunozoguma nekuita kwakarongeka, izvo zvinogona kuderedza huwandu hwekuyerera hunoshandiswa uye kuwana inotaridzika-yakasungwa chigadzirwa.Iko kuchena kweiyo workpiece kuchakanganisawo kuwanda kwe flux coating.

Spray flux

Kupfapfaidza flux pamusoro pezvikamu zvealuminium inzira yakakosha muNocolok.Iyo brazing process, iyo mhando yekupfapfaidza yekupfapfaidza ichakanganisa zvakananga kunaka kwebrazing.Nokuti pane firimu reoxide pamusoro pealuminium.Iyo oxide firimu paaluminium inotadzisa kunyorova kwepamusoro uye kuyerera kwefiber yakanyungudutswa.Iyo oxide film inofanirwa kubviswa kana kubaiwa kuti iite weld.

Basa rekuyerera: 1) Kuparadza iyo oxide firimu pane aruminiyamu pamusoro;2) Kurudzira kunyorova uye kuyerera kwakatsetseka kwe solder;3) Dzivirira nzvimbo kubva pa-oxidizing panguva yekugadzira brazing.Mushure mokunge brazing yapera, iyo inoyerera ichaita firimu rekudzivirira nekunamatira kwakasimba pamusoro pechikamu chealuminium.Iri bhaisikopo harina mhedzisiro yakashata pakuita kwechigadzirwa, asi rinogona kuwedzera zvakanyanya kugona kwezvikamu zvealuminium kuti zvirambe kuora kwekunze.

Huwandu hwekuyerera hwakanamirwa: Munguva yekugadzira brazing, huwandu hwekuyerera hwakasungirirwa: kazhinji 5g yekuyerera pamamita mana;3g per square metre yakajairika mazuva ano.

Flux yekuwedzera nzira:

1) Kune nzira dzakawanda dzakasiyana: kupfapfaidza kwepasi-kudzvanya, kukwesha, kupfapfaidza kwepamusoro-soro, kunyura, kupfapfaidza kwemagetsi;

2) Nzira yakajairika yekuwedzera flux mu controlled atmosphere brazing (c AB) process is suspension spraying;

3) Izvo zvemuviri uye zvemakemikari zvimiro zvekuyerera zvinonyorova kupfapfaidza sarudzo yekutanga;

4) Pasi rose, maererano nenhamba: 80% inoshandisa mvura yakapfapfaidza, 15% inoshandisa spray yakaoma, 5% inosarudza spray kana pre-jasi;

Kupfapfaidza kwemvura ichiri nzira yakajairika yekuyerera muindasitiri uye inopa mhedzisiro yakanaka.

Kuomesa

Kuti uve nechokwadi chemhando yezvikamu zvebrazing, iyo workpiece inofanirwa kuomeswa zvizere isati yabvongodzwa kuti ibvise hunyoro kubva pakuputira.Chinhu chinonyanya kukosha mukuomeswa ndechekudzora tembiricha yekuomesa uye mesh kumhanya;kana tembiricha yakadzikira kana mesh yekumhanyisa inokurumidza, musimboti hauzoomeswa, zvichikonzera kudzikira kwemhando yebrazing kana desoldering.Tembiricha yekuomesa kazhinji iri pakati pe180°C ne250°C.

Brazing

Kupisa kwenzvimbo imwe neimwe muchikamu chebrazing, kukurumidza kwemambure uye mamiriro ekunze echoto chemoto chinodzora kunaka kwebrazing.Kupisa kwebrazing uye nguva yebrazing ichave nemigumisiro yakananga pahutano hwechigadzirwa.Pasinei nokuti kutonhora kwakanyanya kana kuderera, kuchava nemigumisiro yakaipa pane chigadzirwa, sekuderedza hupenyu hwebasa rechigadzirwa, zvichiita kuti urombo husina kunaka hwemutengesi, uye kuderedza kuneta kwechigadzirwa;saka, kudzora tembiricha uye brazing nguva ndiyo kiyi yekugadzira maitiro.

Mhepo iri muchoto chebrazing chinhu chakakosha chinokanganisa chiyero chewelding.Kuti udzivise kuyerera uye zvikamu zvealuminium kubva pakusvibiswa nemhepo, kumhanya kwemesh hakungotaridzi urefu hwenguva yekubhuroka, asi zvakare inotarisisa kugona kwekugadzira.Kana huwandu hweiyo radiator core yakakura, kuitira kuti uwane kupisa kwakakwana kune imwe neimwe nzvimbo (pre-brazing zone, heat zone uye brazing zone) panguva yekushongedza.Iko kumhanya kwetiweki kunoda kunonoka kuitira kuti tembiricha yepasi isvike pakukosha kwemaitiro.Pane zvinopesana, kana huwandu hweiyo radiator core idiki, kumhanya kwetiweki kunoda kuve nekukurumidza.

3. mhedziso

Radiators vakawana zvizvarwa zvitatu zvebudiriro, zvinoti mhangura mhangura, aruminiyamu akagadzirwa marayadhiya uye aluminium brazed radiators.Parizvino, aluminium brazed radiators yave maitiro enguva, nekuenderera mberi kwekusimudzira uye kufambira mberi kwehunyanzvi, uye kuvandudzwa kwemotokari dzakareruka.Aluminium radiators ave achishandiswa zvakanyanya nekuda kwesimba rawo rekudzivirira, kunaka kwekupisa uye huremu huremu.Nekushandiswa kwakakura kwemaaruminiyamu radiators, tsvakiridzo pamusimboti weiyo brazing tekinoroji iri kusimukira zvakare yakanangana nekurerutsa uye kusiyanisa, uye brazing ichiri kubuda welding tekinoroji muindasitiri yekugadzira yealuminium radiators.Inogona kukamurwa kuita mapoka maviri: hapana flux brazing uye flux brazing.Traditional flux brazing inoshandisa chloride se flux kuparadza iyo oxide firimu pane aruminiyamu pamusoro.Nekudaro, kushandiswa kwechloride flux kuchaunza matambudziko anogona kuita ngura.Kuti izvi zviitike, kambani yealuminium yakagadzira isina-corrosive flux inonzi Nocolok.nzira.Nocolok.Brazing ndiyo ramangwana rekusimudzira maitiro, asi Nocolok.Brazing inewo mimwe miganhu.Kubva Nocolok.flux haina kunyungudika mumvura, zvakaoma kupfekedza iyo flux uye inoda kuomeswa.Panguva imwecheteyo, fluoride flux inogona kuita ne magnesium, iyo inomisa kushandiswa kwealuminium zvinhu.Fluoride flux brazing tembiricha yakakwira zvakanyanya.Naizvozvo, iyo Nocolok.nzira ichiri kuda kuvandudzwa.
