Fili brazing aluminum sassa amfani da masana'antu da kuma a cikin gida. Alal misali, a yau ta bike Frames an sanya daga aluminum gami - a cikin matsananci tuki, su sau da yawa karya. A tambaya shi ne: abin da irin solder zabi?

An yi imani da cewa soldering na aluminum - wani hadadden tsari. Amma a gaskiya wannan shi ne yanayin, idan a cikin tsari da yin amfani da kayan for bakin karfe ko tagulla, karfe, tagulla. Dalilin wannan - da oxide fim. Wannan shi ba ya ba da ake so matakin da wettability kuma ba ya soke da tushe karfe.

A soldering aluminum da kuma ta gami

Cewa za a yi aikin a kan kari matakin, da solder for soldering na aluminum kamata dauke da silicon, aluminum, jan, tutiya da azurfa. Yau, kasuwa zai iya samun qagaggun a cikin abin da duk wadannan abubuwan da suke a daban-daban rabbai.

Zabar wani abin dogara solder, shi ne muhimmanci a yi la'akari da wadannan. Matsakaicin lalata juriya da kuma high ƙarfi zai yi da fili da aka yi tare da solder, wanda ya ƙunshi mai yawa tutiya.

Har ila yau aluminum za a iya amfani da mahadi da kuza, da darma akai. Amma yana da muhimmanci sosai shirya aikin surface, goga don tsabtace bakin karfe, da kuma yin amfani da aiki fluxes. Amma masana ba da shawarar yin amfani da irin wannan kashi.

Duk wani solder for high zazzabi aluminum brazing. A mafi kyau duka, da cewa ba da damar samun abin dogara dangane, - aluminum-silicon da aluminum-jan-silicon.

Yadda solder jan?

Kamar yadda aka ambata a sama, yana yiwuwa su yi aiki da mafiya yawa daga cikin qagaggun. Ana iya amfani da a matsayin low-zazzabi low-narkewa da brazing filler karafa. Wani amfani qagaggun dangane tin-gubar, da kuza, da azurfa, da tagulla, da na azurfa, kuma tutiya.

Idan kana so ka gyara kwamfuta motherboard ko gyara TV a kasar, za ka iya amfani da wani fusible abubuwa. Idan ya zama dole to solder kayan aiki a kan bututu ko aikin famfo ko gyara firiji, sa'an nan kawai za su dace da brazing abu don brazing tagulla. Saboda haka yana yiwuwa a sami high quality sakamakon.

bakin karfe

Idan kana so ka hada sassa daga bakin karfe, da kwararru da shawarar yin amfani da maɗaurai da kuza, da darma. kayan da cadmium ne ma da dace. Za ka iya amfani fusible gami bisa tutiya. Duk da haka, da suka kamata ba a yi amfani a tare da carbon ko low-gami steels. Mafi solder for soldering na bakin karfe - mai abun da ke ciki dangane da tsarki tin. Bugu da kari, kawai tin da aka yarda idan soldering wuri zai zama a lamba tare da abinci.

Idan aikin zai iya yi a cikin bushe ko da makera yanayi, sa'an nan su yi amfani da azurfa don manganese, nickel-chromium ko tsarki jan solder (kuma mafi zai fi dacewa tagulla). Lokacin da soldering wajibi ne a lalatattu mahalli, yi amfani da azurfa tinoli karamin sashi na nickel.

Pike karfe

Haša sassa biyu ba su da wuya a juna. Araha da kuma inganci solder for soldering na karfe - POS-41. Akwai kuma wani POS-60 da kuma wasu, ko da m tin za a iya amfani da su. Amma tutiya qagaggun dace bad. Musamman lõkacin da ta je carbon ko low-gami kayan.

Fluxes for brazing

A lokacin aiki da juyi taka wata rawa karami fiye da solder. Wannan sunadarai sauran ƙarfi absorber da oxides. Yana kuma kare da karfe daga hadawan abu da iskar shaka da kuma ƙaruwa wetting.

Don aiki tare da abubuwa a kan tushen da gubar da tin a matsayin juyi za a iya amfani da hydrochloric acid, tutiya chloride. Ma dace rawar soja, ammonium chloride. Wannan aiki fluxes. Domin m hada rosin, man fetur jelly, man zaitun, da kuma wasu abubuwa.

Alal misali, hydrochloric acid mafita za a iya amfani da taushi solders. Tutiya chloride da ake amfani da tagulla, da jan karfe, karfe. Ammonia, barci daidai raba da dissolves da m abubuwa. Domin aluminum amfani da wani abun da ke ciki na tung mai, rosin, calcined tutiya chloride. Zaka kuma iya amfani da wani dabzar phosphoric acid.

Saboda haka, da muka samu daga abin da suke da solders, da kuma wanda yake mafi kyau don amfani a daban-daban lokuta.
