Chii Chatinofanira Kuziva Nezve "Tinning Rods"

Kugadzirira uye zvemhando zvinodiwa zvetinning tsvimbo / mitsetse

Tin tsvimbo, sezvinoreva zita kuti danda solder, inonzi tin rod industry. Inonyanya kushandiswa kune wave soldering uye kunyudzwa welding, parizvino ndiyo yakanyanya kushandiswa yemagetsi solder akasiyana; mari shoma inoshandiswawo pakupisa moto kana solder iron welding yezvikamu zvakakura zvechimiro uye marefu welds. Ndiyo inonyanya kukosha uye yakakosha yekubatanidza zvinhu kune zvese zvigadzirwa zvemagetsi nemagetsi uye kushandiswa kwepagore kwepasi rose kunosvika zana rematani.

Nzira yekugadzirira yetin strip iri nyore, kusanganisira batching, kunyunguduka uye kukanda, uye dhigirii ye oxidation uye zviri mukati mesimbi uye kwete-metal tsvina inodzorwa zvakasimba. Tembiricha yekunyungudika uye tembiricha yekukanda zvine simba guru pamhando yerata. Kugadzirira kwemarata mitsetse kuri nyore uye tekinoroji chikumbaridzo chakaderera, saka kukwikwidza kunotyisa zvakanyanya. Mutengo wazvino uno unongowedzera mari shoma yekugadzira pamutengo wezvigadzirwa. Kana mutengo wezvigadzirwa zvemarata uchinge wachinja zvakanyanya munguva pfupi, purofiti shoma inogona kudzimwa, kana kurasikirwa.

Izvo zvinonyanya kudiwa zvemhando ye tin strip ndezvizvi:

(1) Pepa rerata rakatsetseka;

(2) Kunaka fluidity uye wettability panguva welding;

(3) Yakanaka michina zvinhu;

(4) Bright solder joint;

(5) Mashoma oxidation akasara.

Kukanganisa kwakajairika pamusoro pemarata tambo mavara emaruva uye mabhuru. Izvi zvinokanganisa zvinokonzerwa nekugadzirwa kwekugadzira uye kushandiswa kwezviumbwa. Semuenzaniso, hapana scraping pamusoro panguva yekugadzira, iyo inotonhorera system haina kunaka, uye molds haina kutsvedza, izvo zvinotungamira kumatambudziko ari pamusoro. Chikonzero chekuputika kune chokuita nemamiriro ekunze ayo akaitwa. Vashandi vekugadzira vanotora bhati yetini, usashandise zvakananga ruoko, unyoro huri muruoko huchakanganisa kupenya kwebhati yeti, tin bar version yekushandiswa kwakanakisisa kwepepa repurasitiki, zvose zvinogona kuona kupenya, uye kwete kunyorova. Kana nguva yekuchengetera yareba kana kuti nzvimbo yekuchengetera yanyanya kunyorova, pachave nechikamu che oxide pamusoro pe tin strip, iyo ichaitawo kuti kupenya kwe tin strip kudzima, asi haina mhedzisiro pakushandisa. .

Kukamurwa kwetin strips:

Marata anoiswa muchikamu nekuchengetedzwa kwezvakatipoteredza, kusanganisira marata ane lead nemarata asina lead-isina.

Parizvino, marata anowanzo shandiswa e-lead-free tin strips ndeaya: tin copper lead-free tin strip (Sn99.3Cu0.7), tin silver copper lead-free tin strip (Sn96.5Ag3.0Cu0.5), 0.3 silver lead- yemahara tin strip (Sn99Ag0.3Cu0.7), yakakwirira tembiricha mhando lead-isina tin strip (SnSb).

Iyo inowanzoshandiswa lead tin electrode inonyanya kusanganisira: 63/37 solder bar (Sn63/Pb37), 60/40 solder bar (Sn60/Pb40) uye yakakwirira tembiricha solder bar (400 madhigirii pamusoro welding).

Mukuwedzera kune zvinhu zvikuru zveti, mutungamiri, mhangura, sirivha, kazhinji ine zvishoma zvezvimwe zvinhu, zvakadai se nickel, antimony, bismuth, in, rire pasi uye zvichingodaro.

Aya madiki alloy zvinhu mu tin strip ane simba guru pane yemuviri uye mechanical zvimiro zve tin strip: bismuth inogona kuderedza kunyunguduka tembiricha yetin strip uye kugadzirisa kunyorova nekuparadzira chivakwa, asi yakawandisa bismuth inoderedza kuneta hupenyu uye plasticity ye solder. majoini, uye huwandu hwakakodzera hwebismuth hunenge 0.2 ~ 1.5%. Ni inogona kuvandudza ma mechanic properties uye kuneta hupenyu hwe solder joints nekushandura microstructure uye kunatsa zviyo. Mukugadzirwa kwakarongeka kwemakemikari ekuumbwa, mugadziri ari pachena anotarisira kuti tin strip inogona kuwana chiyero chakaringana muzvinhu zvakasiyana-siyana zvekuita, senge welding performance, tembiricha yekunyungudika, simba, plastiki uye kuneta hupenyu, nezvimwe.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi pepeji rino.
