Copper-phosphorus solder ngokuba nobhedu ngelotha

Amaxesha amaninzi, kuba lo mbutho kweenkqubo amanzi asetyenziswa imibhobho yobhedu. Ukongeza, ezi zinto idla ngokusetyenziswa kuyilo kweendawo zokuhlala yokubhala steampunk. Kungakhathaliseki ukusetyenziswa ekujongwe izinto ezinjalo, imibhobho yobhedu umele ukuba ngandlel 'uqhagamshelo. Indlela elula yokwenza oku ngokusebenzisa copper-phosphorus solder. Kulo mzekelo, okuhlangana uya icocekile kwaye tight. Emva Ukuqinisa i beentanda, uyilo iya kuba namandla pipe mnye-sifuba. Noko ke, ngaphambi kokuba baqale ngelotha yobhedu-phosphorus solder kufuneka ukwazi ezinye iinkalo ngesixhobo apho uya khona wena emsebenzini.

ulwazi Iluncedo malunga ngobhedu

Soft ingxubevange metal waqalisa ukusetyenziswa nokuba kumaxesha amandulo ukuba ayenza. Namhlanje, le nto iye yaba yinto encinane kancane, kodwa inkqubo zokufudumeza kunye vodopovoda eyenziwe imibhobho yobhedu, kusekho i eside kakhulu ethembekileyo ixesha elide.

Ukufakelwa ndlela ikhutshwa phandle ngelotha. Ukusebenza, izinto zesinyithi aba kunye solder - material ngokukodwa esikhethiweyo ukuba indawo yokunyibilika kufuneka ibe ngaphantsi ukuze kugqitywe workpiece.

Inkqubo elula kakhulu ngelotha. Eyona nto ibalulekileyo - ukukhetha umbandela uqhagamshelo ekunene. Kwimeko yethu, le ubhedu-phosphorus solder. Kwakhona kuyimfuneko ukuba kuchazwa indlela ngelotha. Zazo ezininzi.

Iindlela for brazing ubhedu

Ngokuzimeleyo ukudibanisa kombhobho evela imibhobho yobhedu ngeendlela ezimbini:

• lobushushu Low. Le ndlela ilula ezininzi eziqhele ukusetyenziswa kweli khaya. Kule meko a solder elithambileyo inkcenkce, ukukhokela okanye aluminium lwezi methali kongezwe isahlulo zesilivere. Xa esezantsi-ubushushu lokuqhubeka lobushushu yokunyibilika ukuba izinto brazing sobhedu-phosphorus ayikho ngaphezu kweqondo lama-450.
• lobushushu eliphezulu (okuqinileyo). ngelotha olunjalo kunzima yaye kuziindleko ukuba aququzelele ekhaya, njengokuba kulo mzekelo, indawo ukunyibilika umbandela kufuneka ibe phakathi degrees 600 ukuya 900.

Ziziphi izixhobo izofuneka

To connect umgangatho nelembande, kufuneka ngoko nangoko ukulungiselela ezi zixhobo zilandelayo:

• Umsiki. Ngaphandle kwalo, mayingabi sakhululwa ncam kunqunyulwa izinto emgceni. Nikela mgawuli umbhobho, ungenza wenze cut ogqibeleleyo.

solder

Phambi ngelotha umbhobho solder yobhedu-phosphorus, kufuneka uthenge umbandela oza kusebenza njenge yokubopha. Solder nayo iza ngeendlela ezimbini:

• Solid. Loo solder evela ngokohlobo kweentonga elide. Ubume yokuqhagamshelana izinto brand Cu94 P6 kunye Cu92 P6 Ag2 uhlobo eziqinileyo ziquka-6 ekhulwini phosphorous additive, ngoko iqondo eliphezulu avumelekile yesiqalo sayo yokunyibilika na izinyuko 750. Xa olunye uhlobo solder iqulethe akukho ziimveliso ukunciphisa unyango kunokwenzeka thermal, ukuze libe shushu ukuya degrees 900. izinto khabhayithi kokwehla adla ngokusetyenziswa loqhakamshelwano umbhobho igesi, kunye moya amanzi ashushu, kwakunye nangexesha imigca ibandla olusebenza ngamandla.
• Soft. Le solder yale hlobo oluvelayo ngokohlobo ucingo ezingcakacileyo, netoti apho kunqabile idlula 3 mm. izinto Soft ilungele ukusetyenziswa kweli khaya, kwintlangano lothungelwano yonikezelo lwamanzi.

Ukongezelela, kucetyiswa ukuba bathenge wampompoza for solders zobhedu-phosphorus. Le into paste-like, kuthengiswa iingqayi kuyimfuneko ukuze ngokukhawuleza nangempumelelo ekucoceni indawo ipipi amalungu. Wobhobhozayo ususa oxide kunye welds, ukuze ngokwenjenjalo kuphuculwe kakhulu iimpawu solder. Ngaphezu koko, eli candelo kuphucula adhesion le solder kunye umphezulu zobhedu.

Pasta zaveliswa ngenxa solder ethambileyo kunye nzima. Ngoko ke, imfuneko ukukhetha wampompoza esekelwe indlela ekhethiweyo yombhobho joint.

Ngaphandle solder, izitofu kunye nezinye izixhobo, kucetyiswa ukuba ukulungiselela izixhobo. Baya kucelwa ukuba kufuneka wenze ajike main amanzi. Ezi zinto azibizi.

I-copper-phosphorus brazing eziphathekayo ukuze brazing copper: iimpawu

Ukuba sithethe ngale nto, kufuneka sinikele ingqalelo yokuba uye fluidity elungileyo. Ingasetyenziswa kuphela ngokuba nobhedu, kodwa ezinye aluminium.

Ukususela ukwakhiwa kwale nto iquka phosphorus, eye nokumelana, wobhobhozayo nezi- phambili.

Solders uhlobo copper-phosphorus isetyenziswa ngokubanzi yoqhagamshelo izakhi izixhobo abafumana avareji imithwalo vibratory. Ukuba nokwakhiwa umbandela joint kuquka nesilivere, plasticity liphuma amacandelo.

Iintlobo solder ngokuba nobhedu

Ukusingatha imibhobho izinto zilandelayo ezifanelekileyo kule nto;

• 102. Kulo solder-candelo ezintathu ezenziwe ngobhedu, iphosphate ayikho ngaphezu kwe-2% yesilivere. Ngenxa plasticity eliphantsi kuqamba sandiswa kancinci. Ifanele kumacandelo ngelotha yeyiphi akayi ukothuka eyomeleleyo okanye lokungcangcazela.
• 105. Solder copper-phosphorus kunye nesilivere (5%) nazo kakhulu kancinci kwanwenwa, kodwa a ductility ephakamileyo. Efunyenwe ngoncedo zithi ukumelana imithwalo ezincinane ezivela intlokoma.
• 115. Enye solder izithathu, equlethe, ngaphandle yobhedu phosphorus eziqulathwe-15 ekhulwini yesilivere. Yinto impahla entle yeplastiki, ngalo ungenza amalungu koohola abafumana umthwalo eqinile.

Emva kokukhetha onke amacandelo afunekayo iqalisiwe.

ngelotha

Elisezantsi lobushushu-solder efanelekileyo for obandayo uthungelwano unikezelo ukufudumeza amanzi, okanye, ukuba iqondo lobushushu njengesipholisi Iqondo lobushushu lihle laya ngaphantsi kwama-130, yaye sangqa imibhobho yobhedu ayikho ngaphezu kwe-10 cm.

Ukuze enze ngelotha efunekayo:

• Coca imiphezulu ukukhwela.
• Faka ithende kubo.

• Faka izinto zibe omnye komnye.
• Fudumeza indawo joint yi nesikopi ukuya degrees 200-250.
• Faka solder ku iinkcukacha ezininzi buthelezi.
• Ngokuqhubekayo ezihambayo zisiza libe shushu ambaxa imizuzwana 15-20.
• Xa wobhobhozayo kube mnyama, kuyimfuneko ukuba babeke phezu kummandla ngelotha a solder kancinane. Xa izinto eziphathekayo kwakuza kuba phezu kobuso eshushu, kwangoko uqala ukunyibilika kwaye ligcwalise isithuba phakathi kombhobho nezisekelo.

Brazing

Le ndlela wokujoyina imibhobho kuyimfuneko ukuba lobushushu operation Mcetywa lingaphezu degrees 110. Kulo mzekelo, ngelotha lwenziwa yi indlela flame annealing kwaye ithathe izinto zokusebenza.

Xa impahla eqinileyo ayikho kuyimfuneko unyango kumphezulu obhobhozayo.

Ukwenza uqhagamshelwano, kufuneka:

• Qokelela kunye kokumisa efudumeleyo station.
• Yazisa izinto brazing ukuya kummandla apho kwisokethi kunye ityhubhu izinto ezihambelanayo.
• Wathambisa izinto ngokusebenzisa nesikopi gas. Kuyimfuneko ukuqinisekisa ukuba imveliso akuthethi shushu ngokugqithisileyo, ngoko itotshi Kucetyiswa ukuba rhoqo ukuhamba.
• uya izinto umgca nokuhlangana ephambili, jikeleza Xa umbhobho baze ke solder etyhidiweyo kwinxalenye okufuphi.

Le ndlela nzima ngakumbi edlulileyo, kodwa ngelotha oko zinezibonelelo ezininzi:

• Ezivuzayo zinamandla ngakumbi yaye ithembekile.
• Kuyenzeka ukunciphisa kancinci Ububanzi uxhulumaniso, kangangokuba umthungo uya kukhangela zicocekile.

Ukongeza, le ndlela enokusetyenziswa xa ukuyinyusa iinkqubo asebenza kwiqondo lobushushu eliphezulu.

Brazing ubhedu copper-phosphorus brazing yenziwa ngokwe ubuchwepheshe efanayo.

iimpazamo kunokwenzeka njani ukuba sihambisane ngexesha ngelotha

Kule nkqubo, abanye abantu musa ithathele ingqalelo iziphene phezu evele eziqalelo ukuba iqhagamshele. rhoqo ukuba kuvela emva ahlabayo imibhobho. Ukuba ushiya ezi zinto zingalunganga indiva, ngoko akayi kuba robust omhlophe njengoko kuyimfuneko.

Flux kufuneka isetyenziswe ngokulinganayo, ngaphandle izikhewu. Ukuba oko kuya kuba nayiphi na indawo, yombhobho kuqale ngokukhawuleza Rust.

Ukuba inqawe ebilayo kakhulu, i Cola obhobhozayo samaxesha nje. Asinto kwakhona kuhle kakhulu.

Xa ukusebenza ukuba ngokulula ukutsha kakhulu (hayi kuphela edangatyeni inkcukacha, kodwa phezu ukunxibelelana zizinto izidubuli), ngoko phambi kokuba ngelotha, anxibe iiglavu zokuzikhusela, izibuko kunye nempahla.
