Soldering pulasitiki: Zida, Technology

Madzi ndi mpweya mapaipi, zopangidwa pulasitiki, mofulumira ndi molimba mtima m'malo zitsulo akapolo anzawo akale. Zimenezi n'zosadabwitsa, chifukwa zinthu ngati kulankhulana amasiyana kulemera kuwala, kudalilika, chomasuka unsembe. Komabe, pamene khazikitsa chitoliro pulasitiki zambiri zofunika kulenga kugwirizana ndi zotsatira matenthedwe pa m'mphepete zakuthupi. Tiyeni tione mmene angachitire soldering pulasitiki, zipangizo angagwiritsidwe ntchito zolinga zimenezi.

Pike makina apadera kuwotcherera

Soldering Pulasitiki ndi mtundu wa "chitsulo" muli maenje kwa mapaipi a diameters osiyana. M'mbali mwa yotsirizira anayikidwa mu mipata yoyenera, kenako usavutike kutentha kusungunuka.

soldering pulasitiki imagwiridwa ntchito chipangizo mu ndondomeko izi:

1. Chimodzimodzi mapeto kagawo ka chubu anaikapo mu Kutentha wamanja. chipangizo chikugwirizana ndi mains lapansi. Zitsulo ndege wagawo ndi mkangano kuti kutentha ankafuna. Komanso, m'mphepete mwa yamachubu pulasitiki ndi kusungunuka.
2. Pambuyo pokonza mfundo chubu mwadzidzidzi kuchotsedwa mwake ndipo ali cholukanalukana mu zovekera lapansi. Mu malo a m'mbali mating ayenera kupanga kuchuluka kwambiri zakuthupi chosungunula.
3. Pamaso chithandizo matenthedwe m'mbali mwa makina lotsatira chitoliro kuwotcherera bwino kutsukidwa ku zotsala za nkhaniyo mazira.

Soldering pulasitiki otentha zitsulo

The njira zophweka kwambiri, angakwanitse, koma zochepa odalirika kujowina zinthu zopangidwa nkhani pulasitiki - zotsatira matenthedwe ntchito zitsulo mkangano. Pankhaniyi ndi kutentha kokwanira mbale chitsulo kapena zina chida chilichonse abwino. Last zofunika logwirana mu vise, ndiyeno Osatsamira pamwamba otentha mbali m'mphepete. Kamodzi maphatikizidwe kumachitika zinthu zoyenera, ayenera kuchotsedwa mbale mbamuikha mwamphamvu pamodzi.

Pamaso soldering unapangidwa pulasitiki mu njira iyi, izo tikulimbikitsidwa kuti ayeretse pamwamba pa ziwalo kuchokera Mankhwala oipitsa iliyonse yomwe angathe kulepheretsa ngalawayo itafika kumzinda zinthu wandiweyani. Ngati zipangizo ali bii ophikira, monga mankhwala oyeretsera si mowa, acetone kapena mzimu woyera.

Soldering ntchito mpweya burner

Brazing pulasitiki manja awo angathe kuchitidwa mpweya mkangano wochokera burner nozzle. Monga adzapereke akhoza pano kutumikira winawake, carbon dioxide, argon. Kusankha mtundu wa chinthu gaseous zimadalira maonekedwe a pulasitiki kukhala atengeke kusungunuka. Khalani limasonyeza kuti mankhwala khola kwambiri pa ndondomeko matenthedwe mbali mankhwala pulasitiki zimathandiza kupeza Kutentha kwa argon kapena zinthu asafe.

Anapereka soldering luso chimathandiza kuphedwa kwa ntchito ndi popanda zina. Mbali yoyamba ntchito ndodo pulasitiki ndi awiri osati choposa 6 mm, zomwe zimathandiza kuti alenge maphatikizidwe ndi mokwanira woonda, zaukhondo, koma pa nthawi yomweyo msoko mphamvu. zowonjezera izipangidwa zakuthupi zofanana kwa membala kulumikiza.

Pamene ntchito mpweya burner pa kuchoka kwa nozzle zida kutentha ayenera anakhalabe osachepera 50 ° ^C kuposa Sungunulani otaya index zakuthupi kukonzedwa.

The njira processing ndi zogwirizana osati pakakhala kugwirizana chitoliro, komanso milandu kumene ayambe galimoto bampala, zinthu zamkati zina. Zikatero amagwiritsidwa ntchito kawirikawiri kwa soldering mauna pulasitiki yomwe superimposed pa malo zowonongeka, ndiye anatsanulira zinthu chosungunula.

choumitsira Brazing

Pakuti kugwirizana kwa zinthu pulasitiki yabwino kutentha mfuti. Apa, magetsi a pamwamba ntchito amaperekedwa ndi kulumikiza zida kuti mains lapansi.

Choumitsira kwa brazing limapangidwa limagwirira ndi amene amathandiza yunifolomu kufalitsidwa kwa mpweya mkangano pamwamba pa workpiece lapansi. Kuonetsetsa zolimba kugwirizana khalidwe mbali pulasitiki, mitundu yonse ya nozzles ntchito mu ndondomeko yadothi. kukula ndi mawonekedwe amasankhidwa malingana ndi chikhalidwe cha zipangizo ndi kukonzedwa.

Soldering ntchito solvents mankhwala

Kulumikizana mbali pulasitiki ndi njira pano kumaphatikizapo wetting zinthu zosungunulira. Patapita nthawi ya polima ayamba pathupi ndi kukhala dongosolo viscous. Pomaliza zinthu doko zokwanira ndi ena nthawi adzawalange opanikizika mpaka nthawi imene msoko ndi waumitsanso. Mankhwala kupeza mphamvu pambuyo maola angapo. Kuti imathandizira ndondomeko amaloledwa zimakhudzira padziko kutentha negligible, potero mofulumira vaporization wa zosungunulira kwa kapangidwe nsalu.

Pang'ono crystalline mapulasitiki ndi kugonjetsedwa solvents mankhwala. Choncho, apa umaimiridwa ndi soldering adzakhala sizithandiza. Nthawi zambiri agwiritsa ntchito pamene njira ya processing chizindikiro cha nkhani anapangidwa kuchokera thermoplastics amorphous.

Amagwiritsa ntchito mankhwala mutuluka njira zimakhalanso zotsika mtengo amachitira mbali pulasitiki. Komabe, Ndi bwino kuti agwiritsa ntchito pokha pokha kwambiri pamene palibe kuthekera kugwiritsa ntchito chida apadera. Monga solvents mu ambiri chakhala chikugwiritsidwa ntchito poizoni ndi evaporation zoipa thanzi.

pomaliza

Pamene mapeto tisaiwale kuti soldering pulasitiki bwino kukwaniritsa kutsogolo ndi mbali lamkati la zinthu, koma ndi khoma makulidwe a osachepera 5 mm. Pambuyo solidification la mankhwala amachitidwa komaliza akukuta kali ndi opukutidwa, shpaklyuyut ndi okonzekera kupenta. Monga mmene taonera, soldering pulasitiki ndi zotheka ndithu ntchito. Chofunika - ndi zida zofunikira ndi zinthu mwamphamvu malinga ndi malangizo.
