Olee otú ịhọrọ a soldering agbanwe oge

The kasị mkpa maka idozi ọ bụla ngwa bụ soldering. Solder, agbanwe agbanwe oge, solder tapawa - niile a ga-atụle mgbe arụ di ike. Ọ bụrụ na solder niile dịtụ doro anya na - a na-eji maka nke a tin-edu ndú solders dị iche iche na -agbaze okpomọkụ (dabere na alloy mejupụtara), ihe banyere agbanwe oge? Gịnị ka ọ bụ n'ihi na?

Isi nzube nke a agbanwe oge - wepụ oxides n'elu, na-ibelata n'elu erughị ala ka mma n'ịgbasa solder. Ọzọkwa, agbanwe agbanwe oge maka soldering na-eje ozi na-echebe nkwụsị si mpụga gburugburu ebe obibi.

Gịnị bụ fluxes

Site ya ihe, dọgburu na metal na-ebupụta, fluxes bụ nke ndị na-esonụ ụdị.

• Active (na-akpọ acidic). Na ha mejupụtara nwere hydrochloric acid, fluorides na chlorides ọla. Active brazing agbanwe oge dissolves ngwa ngwa oxide film kpụrụ na metal n'elu, si otú na-enye elu n'ibu ike n'ọdịnihu njikọ. Ọ ga-eti na-arụsi ọrụ ike agbanwe agbanwe oge adịghị mma maka idozi ọkụ na ngwá, dị ka ya remnants emecha corrode e jikọtara.
• Acid-free. Ndị a gụnyere rosin, nakwa dị ka kwadebere na ndabere nke rosin agbanwe oge na mgbakwunye na nke turpentine, mmanya ma ọ bụ glycerin. Acid-free soldering agbanwe oge bụghị naanị na ọ dị ọcha na metal n'elu oxides, ma na-echebe ya si n'ihu ọxịdashọn. Ọzọkwa, na ojiji nke rosin adịghị akpata corrosion nke elu. A na-eji maka soldering ọla kọpa, ọla kọpa na ọla ngwaahịa.
• Rụọ ọrụ. Na-kwadebere si rosin, nke na-kwukwara obere site ma ọ bụ aniline hydrochloride, salicylic acid na diethylamine hydrochloride. The ọrụ agbanwe oge maka soldering ga-eji na a dịgasị iche iche nke ọla na alloys (ígwè, ọla kọpa, nickel, ọla kọpa, nickel chromium, silver, nchara). Ọ nwekwara ike-eji maka brazing akụkụ mere nke oxidized ọla kọpa alloys enweghị tupu agba.
• Anticorrosion. Ndị a fluxes na-mere nke phosphoric acid na mgbakwunye na nke dị iche iche organic solvents na ogige. Ọzọkwa, ihe ndị mejupụtara nke ụfọdụ n'ime ndị a fluxes pụrụ ịgụnye organic asịd. Corrosive agbanwe oge na-eji maka brazing ọla kọpa na ya alloys, na ọla-ọcha, platinum na constantan.
• Echebe. Ndị a gụnyere olive mmanụ, waxes, mmanụ ala jelii, powdered sugar. Echebe fluxes enweghị metal chemical ihe, dị ka nke ọma dị ka chebe kpochara n'elu site ọxịdashọn.

Ke adianade do, solder ngwaahịa si nkedo ígwè, carbon steels, na ọla kọpa na ya alloys na-eji borax (sodium tetraborate), nke bụ a na-acha ọcha crystalline ntụ ntụ na-enwe a agbaze okpomọkụ nke 741 ° ^C.

Ọzọkwa borax (ma ọ bụ kama, ya ngwakọta na boric acid na a ruru nke 1: 1) na-eji maka brazing igwe anaghị agba nchara na ihe siri ike elu-okpomọkụ alloys.

Dị ka agbanwe agbanwe oge maka ọla ngwaahịa, a ngwakọta esịnede hà akụkụ nke sodium chloride na calcium chloride.

Brazing nke aluminum isiokwu a chọrọ agbanwe agbanwe oge na-enwe a ala agbaze ebe. A, agbanwe agbanwe oge maka aluminum brazing gụnyere 30 50% potassium chloride.

Agbanwe oge maka soldering ike-emepụta n'ụdị ntụ ntụ, mmiri mmiri ma ọ bụ tapawa. Ọzọkwa, e nwere ndị pụrụ iche solder tapawa nke solder ahụ na-ẹdude ọnụ na-ama submerged.

Gịnị bụ mkpa ịma mgbe brazing

Mgbe ị na-ahọrọ a brazing agbanwe oge na-sonye na akaụntụ bụghị naanị ihe ọmụma si na nke mere ka akụkụ na-soldered, ma nke na-eji solder. The agbaze n'ókè nke agbanwe agbanwe oge ekwesịghị gafere agbaze okpomọkụ nke solder.

N'agbanyeghị nke ụdị soldering agbanwe oge ohere mgbe ngwa ga-kpochapụrụ na a ákwà tinye ke acetone ma ọ bụ adị spirit. Mgbe ahụ, hichaa ebe a ahịhịa ma ọ bụ ahịhịa gwara ọ bụla mgbaze wepụ agbanwe oge residues. Nke a bụ eziokwu karịsịa nke nọ n'ọrụ agbanwe oge, ebe ọ bụ ya decomposition ngwaahịa adịghị naanị emetọ brazed ma na-n'ekwú corrosion.
