Copper-phosphorus solder for zethusi nokunamathisela ngomthofu

Ngokuvamile, le nhlangano yamanzi izinhlelo esetshenziswa amapayipi zethusi. Ngaphezu kwalokho, lezi zinto avame ukusetshenziswa lapho kwenziwa umklamo kwezakhiwo zokuhlala isitayela Steampunk. Kungakhathaliseki ukusetshenziswa okuhloswe izici eziningana ezinjengolwazi, amapayipi zethusi kumelwe ngandlela-thile kuchunywa. Indlela elula yokwenza lokhu ngokusebenzisa yethusi-phosphorus solder. Kulokhu, lapho kuhlangana ngeke lihlale ezihambisanayo. Ngemva solidification we ezivuzayo, umklamo kuyoba njengoba donsile njengoba eyodwa isiqeshana ipayipi. Nokho, ngaphambi kokuba baqale nokunamathisela ngomthofu zethusi-phosphorus solder kufanele wazi izici ezithile ezibonakalayo ngawo ozosebenza.

Ulwazi olubalulekile mayelana zethusi

Soft ingxubevange metal zaqala ukusetshenziswa ngisho endulo ngoba ayenza lezi zinhlamvu. Namuhla, le nto isibe kancane kancane ethandwa, kodwa uhlelo Ukushisa vodopovoda eyenziwe amapayipi ithusi, Namanje eside kakhulu okunokwethenjelwa futhi iqine.

Ukufakwa migwaqo Kwenziwa nokunamathisela ngomthofu. Ngo kokuhlinzwa, izakhi zensimbi zihlangene ne solder - material ezikhethiwe kokuba lokuncibilika Kufanele ibe ngaphansi ukuze endaweni workpiece.

I silula inqubo nokunamathisela ngomthofu. Into esemqoka - ukukhetha ilungelo impahla uxhumano. Esimweni sethu, lokhu solder zethusi-phosphorus. Kuyadingeka ukuba achazwe nge indlela nokunamathisela ngomthofu. Zabo ziyisiliva eziningana.

Izindlela ze-copper brazing

Ngokuzimela ukuxhuma ipayipi kusuka amapayipi zethusi ngezindlela ezimbili:

• lokushisa okuphansi. Le ndlela iyona elula futhi ngokuvamile ezisetshenziswa ekhaya. Kulokhu a solder ezithambile tin, ukuhola noma Alloys lezi zinsimbi ne kwalokho ingxenye esiliva. Lapho aphansi-lokushisa kucutshungulwa lokushisa ukuncibilika zethusi-phosphorus brazing impahla akuyona degrees abangaphezu kuka-450.
• lokushisa High (okuqinile). nokunamathisela ngomthofu enjalo kunzima futhi kuyabiza ukuhlela ekhaya, njengoba kulokhu, iphuzu ukuncibilika impahla kumele abe phakathi degrees 600 kuya ku-900.

Yimaphi amathuluzi kuyodingeka

Ukuze uxhume izinga ipayipi, kumelwe ngokushesha ukulungiselela amathuluzi ezilandelayo:

• Umsiki. Ngaphandle kwayo, asikwazi ngempela usike izakhi umugqa. Esebenzisa umsiki ipayipi, ungenza Imi ephelele.

• skimmers Flat. Leli thuluzi kuyadingeka elizofinyezwa emaphethelweni Imi ashanele ipayipi ukuba baphathe eliphezulu dock izingxenye.
• Expander. Uma e inqubo uhlela ukusebenzisa couplings kanye nokufakwa kwayo, sibonga leli thuluzi ke sizokwazi ngokushesha ukwandisa ingxenye ye-ipayipi usayizi oyifunayo.
• Emabhulashini kanye shayela. Ngemva brazing, tube kubalulekile ukuhlanza zokwakheka oxide.
• Kugqame. It is ogibele umlomo wombhobho sikaphalafini ukuze uqondise ilangabi endaweni ethize. Uma ungenalo wamisa kugqame, ie ingozi ukulimala izinto eziseduze.
• Sikaphalafini igesi. Yenzelwe amalahle brazing zethusi-phosphorus.

On the last ithuluzi zokusebenza kufanele ukukutshela okwengeziwe.

igesi sikaphalafini

Lokho iphayiphi is soldered kahle, udinga ukuba banakekele kukhethwa sikaphalafini efanelekayo. Amathuluzi kukhona:

• Nge amasilinda alahlwayo (yasendlini).
• Nge isilinda umile.
• Acetyl umoya-mpilo.

Uhlobo lokugcina eliphezulu uxhumano amapayipi zethusi. Lokho ithoshi futhi udinga ukuthenga.

Futhi, amadivayisi zingafani amandla Ukushisa solder. Ayanda lokushisa Ukushisa, yidivayisi enamandla ngaphezulu kumele. Ngakho:

• Ukuze solder ezithambile eshibhile ofanele futhi isibani kangako. Ngakho-ke, ungakwazi ngokuphepha ukuthenga ithuluzi lulwimi professional nge gas termofenom. a sikaphalafini ezinjalo okwazi lokushisa kuze kufinyelele 650 degrees. Inzuzo enkulu ithuluzi ezifana ukuthi kungenzeka elawula umfutho ilangabi. Ngakho, kungenzeka ukukhetha elikhulu lokushisa ukuncibilika imodi.
• Ukuze braze kudingeka ithuluzi professional, obiza kuyoba izikhathi eziningana ephakeme. Ngakho-ke, akunandaba mqondo ukuchitha imali, kodwa uma ufuna ngempela, ke kungani kungenjalo.

solder

Ngaphambi nokunamathisela ngomthofu ithusi-phosphorus solder ipayipi, udinga ukuthenga impahla ukuthi uyokwenza njengendlela yokuhlanganisa. Solder futhi kunhlobo ezimbili:

• Solid. a solder okunjalo ikhiqizwa ngesimo izinduku ezinde. Isakhiwo yokuxhuma izinto brand Cu94 P6 futhi Cu92 P6 Ag2 uhlobo okuqinile zihlanganisa kwamaphesenti angu-6 phosphorous okufakiwe, ngakho esiphezulu lokushisa avumelekile ukuncibilika yayo Iphuzu liwukuthi 750 degrees. Kolunye uhlobo solder aluqukethanga izinto okuyinto ukunciphisa kungenzeka ukwelashwa ezishisayo, ukuze bakwazi sishiswa kuze kube degrees 900. Waqinisa Carbide izinto avame ukusetshenziswa yokuxhuma ipayipi igesi ukuthengisela, namanzi ashisayo conditioning, kanye ngesikhathi inhlangano imigqa ezisebenza ngomfutho ophakeme.
• Soft. I solder yalolu hlobo ikhiqizwa ngesimo wire elincanyana, ububanzi okuyinto akuvamile idlula 3 mm. impahla Soft kuyinto ekahle ukusetshenziswa ekhaya, enhlanganweni amanzi amanethiwekhi.

Ngaphezu kwalokho, kunconywa ukuthenga yokucucuza zethusi-phosphorus solders. Le into unamathisele-like, sithengiswa izimbiza kuyadingeka ukuze ngokushesha nangempumelelo ukuhlanza indawo pipe amalunga omzimba. Yokucucuza kususa oxide ne welds ezinhle, kanjalo ngcono kakhulu izimfanelo solder. Ngaphezu kwalokho, le ngxenye sithuthukisa adhesion we solder kanye ebusweni zethusi.

Pasta okukhiqizwayo solder esithambile futhi kanzima. Ngakho-ke, isidingo ukhethe ecucuza esekelwe indlela ekhethiwe joint ipayipi.

Ngaphandle solder, izitofu kanye namanye amathuluzi, kutuswa ukulungiselela nokufakwa. Bayobe kuyadingeka uma kufanele wenze Uphendula amanzi main. Lezo zinto engabizi.

Ithusi-phosphorus brazing zethu ezingokwenyama brazing yethusi: izici

Uma sikhuluma lento, kufanele sinake yokuthi anakho fluidity ezinhle. Ingasetshenziselwa hhayi kuphela zethusi, kodwa nezezinye Alloys.

Kusukela Ukwakheka kwale nto kuhlanganisa i-phosphorus, esesikhundleni ukugqwala ukumelana, yokucucuza ungaqhubeka ukuthola.

Solders zethusi-phosphorus uhlobo ngokuvamile esetshenziselwa uxhumano izakhi imishini uhlangabezana isilinganiso imithwalo vibratory. Uma indlela yokwakheka impahla ngokuhlanganyela kuhlanganisa nesiliva, plasticity liphuma izingxenye.

Izinhlobonhlobo solder for zethusi

Ukusingatha amapayipi izinto ezilandelayo Site le nto:

• 102. Kulesi solder emithathu ingxenye ezazenziwe ngethusi ne phosphorus akuyona ezingaphezu kuka-2% esiliva. Ngenxa plasticity ongaphakeme Ukwakheka zibhebhetheka kancane. Ifanele izingxenye nokunamathisela ngomthofu ezingenakho ibhekane ukushaqeka eqinile noma vibration.
• 105. Solder zethusi-phosphorus kanye nesiliva (5%) nazo ngempela kancane zibhebhetheka, kodwa has a ductility ephakeme. Etholwe ngosizo ngokuhlanganyela zingamelana imithwalo encane evela kunyakaza.
• 115. Omunye solder ternary, equkethe, ngaphandle zethusi ne phosphorus equkethwe amaphesenti 15 esiliva. Kuyinto impahla kuhle plastic, ngawo ungakha emalungeni emigwaqweni uhlangabezana umthwalo ngempela eqinile.

Ngemva kokukhetha zonke izakhi ezidingekayo iqalisiwe.

nokunamathisela ngomthofu

Low-lokushisa solder efanelekayo lokukhuphula Ukushisa kwamanzi emapayipini noma, uma izinga lokushisa kokupholisayo lingaphansi kuka 130 degrees, futhi ububanzi we amapayipi zethusi akuyona engaphezu kuka-10 cm.

Ukuze enze nokunamathisela ngomthofu ezidingekayo:

• Hlanza evele kokuzalela.
• Sebenzisa ecucuza kubo.

• Faka izakhi ku nomunye.
• Shisisa endaweni ngokuhlanganyela ngumuntu sikaphalafini ukuba 200-250 degrees.
• Sebenzisa solder lemininingwane kakhulu onqenqemeni.
• Ngokuqhubekayo ezihambayo sikaphalafini ukufudumeza kwakwakhe imizuzwana 15-20.
• Lapho yokucucuza kube mnyama, kubalulekile ukuba walala phezu zone nokunamathisela ngomthofu a solder kancane. Uma le ndaba phezu evuthayo, ngokushesha uqala zigcwale amanzi bese ugcwalisa isikhala esiphakathi ipayipi nezisekelo.

Brazing

Le ndlela zokujoyina amapayipi ezidingekayo uma ukusebenza iphayiphi lokushisa udlula degrees 110. Kulokhu, nokunamathisela ngomthofu wenziwa ilangabi annealing indlela wacabangela material ukusebenza.

Lapho impahla okuqinile akudingekile ekwelapheni evele yokucucuza.

Ukuze wenze uxhumano, kumele:

• Qoqa bese uMpheme weNsiza yeDeskithophu efudumele.
• Ukwethula izinto brazing ku esifundeni lapho isokhethi kanye tube aba oxhumene.
• Ukuthambisa impahla esebenzisa sikaphalafini igesi. Kuyadingeka ukuqinisekisa ukuthi umkhiqizo akusho overheat, ngakho ithoshi Kunconywa ukuba njalo ukuhambisa.
• Izoqala nini le eyinhloko izakhi elihlangana umugqa, ukushintshanisa ipayipi futhi umoya solder oncibilikisiwe kungxenye eduze.

Le ndlela nokunamathisela ngomthofu nzima langaphambilini, kodwa kunezinzuzo eziningana:

• Ezivuzayo kukhona eziqine kakhudlwana futhi enokwethenjelwa.
• Kungenzeka ukuba kancane ukunciphisa ububanzi uxhumano, ukuze umphetho uyobheka kwenetha.

Ngaphezu kwalokho, le ndlela singasetshenziswa lapho obandayo izinhlelo letisebenta okushisa kuqhathaniswa eliphezulu.

Brazing zethusi zethusi-phosphorus brazing Kwenziwa ngokuvumelana ubuchwepheshe obufanayo.

amaphutha kungenzeka ukuthi kungenziwa ibekezelelwe ngesikhathi nokunamathisela ngomthofu

Phakathi nalokho kubingelelana, abanye abantu musa acabangele izici Laphezu izici ukuba axhunyiwe. Isikhathi esining impela avele emva ukusika amapayipi. Uma ushiya lezi ukukhubazeka zishaywa indiva, bese umphetho ngeke eyizingqabavu njengoba kudingeka.

Flux okumele asetshenziswe ngokulinganayo, ngaphandle izikhala. Uma-ke ngeke kunoma iyiphi indawo, iphayiphi angaqala angabacwasi ngokushesha nokugqwala.

Uma ipayipi is ebilayo kakhulu, unama ecucuza nje ashise. Libuye kahle.

Ngo ukusebenza kalula nje ubangele i ukusha sina (hhayi kuphela ilangabi sikaphalafini, kodwa futhi phezu contact nge izinto esisheshayo), ngakho ngaphambi nokunamathisela ngomthofu, ukugqoka zokuzivikela amagilavu, amagogolo nezingubo ngokuphazima kweso.
