Kodi solder

Funso ndi momwe solder, chifukwa masiku kunyumba amisiri ndi amaphunzitsidwa madokotala Sikuti lero. Koma pamene izo zifika mpaka ku izo, likukhalira ngati kuti nthabwala za Leo Tolstoy, amene ankakonda kusewera balalaika, koma mwatsoka sakanakhoza.

Popeza ambuye anaphunzira kusungunula otsogolera malata anali tinkers, amene ankachita akusowekapo soldering zitsulo.

Anayamba isanayambe soldering ndi kuwavula ndi degreased ndi mafuta. Mbola mkangano soldering chitsulo choviikidwa mu rosin kapena ammonia. Ngati utsi amawonetsa ofooka, zikutanthauza kuti chitsulo soldering ndi wokonzeka ntchito.

Ayeretsa rosin soldering nsonga kwa oxides zitsulo. Woyengeka soldering nsonga choviikidwa mu solder (zambiri malata) ndipo unachitikira kumeneko kufikira yokutidwa ndi zojambulazo. filimuyi imafalira pamwamba pa danga yakumapeto, i.e. "Tin" izo. Ndiye, pa mphambano ya anasamutsa chochuluka solder chimene chili chofunika kugwirizanitsa workpieces.

Kodi solder popanda kugwiritsa ntchito chitsulo soldering? N'zotheka ntchito mankhwala omwe akhoza kumasula "solder" ndi kuwonjezeka mu kutentha awo. Izi solder phala. Iwo n'zofunika kwambiri soldering ku malo akutali. phala The umagwiritsidwa ntchito pa malo ziwirizi ndi mkangano.

Tsopano tiyeni tiwone momwe solder zotayidwa. Si zophweka kuchita, popeza kuyeretsa pamwamba pa filimu zotayidwa okusayidi aumbike kachiwiri. Kukhalapo filimu imeneyi amachepetsa chomangira mphamvu. Choncho, nthawi yomweyo pambuyo kukonza pamwamba pa malo mphambano pa workpiece zotayidwa anatsanulira kamwazi chabe. Iyi ndi rosin, glycerol ndipo aliyense wa mafuta zidulo.

Zotayidwa solder ndi amphamvu soldering. Ngati bwino anasankha kamwazi, zitsulo zotayidwa mosavuta soldered. pamwamba pake cha waya tinned mkuwa akhoza soldered popanda vuto.

Pali njira ina: pamwamba wosanjikiza zotayidwa nakonza preform ndi afewetsedwa rosin, mkuwa ufa n'kuwaza. Pambuyo opaleshoni, soldering mbali angathe kuchitidwa mu alipidwa soldering lata.

Si kale m'malo mwa mipope zitsulo anabwera katundu pulasitiki. Kodi solder mipope pulasitiki? Iwo umachita izo kovuta ngati pali chida zofunika kuwotcherera awo.

Pa Kutentha zida Ufumuyo nozzle chofunika kukula. The yang'anira wayikidwa kutentha pa 2700 Celsius.

Ngakhale nozzle mkangano pa makina kuwotcherera, kukonzekera ndi kudula kutalika ofunikira chitoliro lapansi. Amafuna burrs kuchotsedwa ndi roughness, kenako chitoliro aikidwa chizindikiro wofanana ndi akuya koyenera lapansi. Pambuyo Kutentha chitoliro akulowa koyenera pa inu limatanthauza kutalika. The pamalo kuwotcherera ali degreased. Tsopano ndi nthawi Kutentha ndi soldering.

The nozzle mkangano kutayidwa kumbali imodzi ya zida za kuwotcherera koyamba kuvala loyenera, chifukwa akusonyeza makoma chachikulu, chimene chimafuna Kutentha yaitali. M'pake ayenera kutsimikiza pansi pa nozzle lapansi. Mosiyana ndi kuwotcherera makina kwa nozzle chachiwiri "akukhala" chitoliro pulasitiki.

Zochangamutsa nthawi ya chitoliro ndi koyenera ndi kutchulidwa malangizo kwa makina kuwotcherera. Pa nthawi ya magetsi a mbali iwo sayesa atembenuza, kuyambira zingayambitse psinjika pulasitiki.

Atakula Kutentha nthawi, zinthu ndi kuchotsedwa nozzles, ndipo umayamba pang'onopang'ono mu chitoliro koyenera chizindikiro anapanga kale. Kupotokola zidutswa ntchito sangathe.

Tsopano inu mukudziwa momwe solder mipope pulasitiki.
