Solder yesilivere ntoni na? Properties neefoto

Ukuze songe imali, abaninzi ezenziwe solder zesilivere ngesandla. Makhe achaze iimpawu ubuchwepheshe, izicelo ze ingxubevange ogqityiweyo.

Ukuba uqinisekile amakhono abo, kungcono ukuthenga ipasta esele zenziwe kwaye ukuchitha ixesha imifuniselo ezingaqondakaliyo.

Yintoni i ingxubevange

loqobo - a metal ethambileyo, ngoko ke akukho ezifanelekileyo umsebenzi. Ngokomthetho iinkosi kusebenza umxube leyo ubunjwe zinc, nickel,-aluminiyam, ikopolo kunye isiqalelo esithambileyo esimhlophe. Le solders isilivere ngaphezu kwesilivere ziquka izinc nangobhedu. Le umthungo wakhiwa sisincoko onjalo, wafumana olomeleleyo ixesha elide.

Le iikhompawundi zesilivere, nobhedu, nezinki, ube nekhono eliphezulu ukuya kwawe. Bona zisetyenziselwa solder yesilivere. Ukulawula isakhiwo layo lenzala yenzelwe GOST 19746 74. Solders, ibakala isilivere usoloko kucacisiwe imiyalelo ukuya kwimveliso. Solder umthungo, nto leyo ifunyenwe kule ndlela ifunyenwe a eqinileyo.

PSrMts Solder brand 37

wire solder yesilivere (37 PSrMts kunye Yosep-25) isetyenziselwa ukudibanisa Imiphezulu ezenziwe ngobhedu. Ifomu ngokuba yezandla walo iphepha okuqhubekayo. It isikwe imicu olulingana 1.5-2 mm. Izikhewu phakathi iindawo wokujoyina azaliswe solder yesilivere, ekwaziyo withstanding deformation ngoomatshini kunye ukungcangcazela.

chemical ukubunjwa

inkqubo technology isekelwe phezu ukusetyenziswa solder zesilivere, eyenzelwe ngelotha inyathelo. Njengoko solder kufuneka zingamelana ukuya ku-600 ° C, amacandelo alo: 33% isiqalelo esithambileyo esimhlophe, 30% zesilivere,-16% zinc,-20% zezobhedu. Le yokuqamba kunokuba ethe, abakwazi ukumelana intlokoma. Xa isixa zesilivere 52% umxube ulwelo ifunyenwe ukumelana ngelotha multistage.

Main yokupheka iresiphi solder yesilivere

Makhe sibone ukuba ukwenza njani na solder yesilivere ekhaya. Kukho iinketho eziliqela umenzi wayo, nganye bokuqonda yayo. Ukuze ufumane i-ingqekembe ingxubevange iyafuneka (iirandi ezingamashumi amahlanu) 1924 , kwakunye iisenti ezintlanu ngo-1962. Ukuze asebenze ezidingekayo: Ingus, nesilivere, sokukhuphela igesi, ngecephe.

Manufacturing of solder zesilivere iqala bayinyibilikisa metal anqabileyo. Emva koko faka lwemali nickels. Ukuze udlwabevu ngokupheleleyo, umxube lwaqatsela phezu icephe. Ngethuba lokuqhuba kwale nkqubo kuxhomekeke kwiziphumo lokugqibela elisetyenziswa. Igalelo elibi eli bugcisa ukutshisa amacandelo yemichiza ezifunekayo ukuze solder. Okulandelayo, i wizard qamba izandla zakhe ingxubevange uyitha libe Ingus ngaphandle ukudubula rolls. Le solder Umphumela uba sample-900. Xa ngelotha ekubhobhozeni kufuneka ilungiswe entsha, ukuqinisekisa umgangatho womsebenzi. Master igcina umkhondo idangatye kwi zisiza igesi ukutywina ifunyenwe noba kwaye ixesha elide.

imisebenzi technical

Kuba amaphepha zobugcisa solder yesilivere eziquka iindawo 80 zesilivere, nobhedu 16, 4 zinc kusetyenziswa. Of umdla solder ubucwebe yesilivere, ogama yokuqamba: 2.8 iindawo nobhedu, 7 - zesilivere, 0.2 - zinc. Phambi kokuba umsebenzi ikhutshwa phandle bavune ngobhedu oxide film. Ukuze ufumane 10 iigrem le solder 999 yisilivere otyhidiweyo. Brass idityaniswe intsimbi engamanzi, likuxhoxhela icephe. Emva yokunyibilika epheleleyo umxube lahlanganisa zinc, ukwakhiwa ngenxa liqengqwa. sheet Further liqengqiwe, uyagawulwa kunye izikere ndamlinganisela phezu esikalini. Kuba umsebenzi ngempumelelo ezifunekayo: icephe, sandpaper, nesikopi igesi, isikali, izaphulelo zemali, kuba icephe ukuxuba. solders Silver musa nobhedu, nesilivere, izinc ecocekileyo iboraksi. Manufacturing isisombululo yobugcisa isilivere solder iisampulu 94 okanye 96. Fumana itoti metal ngexesha yokutsha Stars: qhina, qhina, brocades.

solder kwawe

Ziya kunyibilika iintsimbi ezo ziyinxalenye umxube afunyenwe kwi solder ngokuyinyibilikisa zesilivere for steel. Beka gel kwelo ziko, ukulungiselela izixhobo ezizodwa: iboraksi, isikhongozelo yamanzi, umxube గుర్తులు ibhaloni zentsimbi hook ngokuyinyibilikisa. Okokuqala kuyimfuneko ukunyibilika eliyinjubaqa uze kongezelelwa ngomxube zesinyithi fusible. Ukwenza ngezandla zakhe solder umgangatho ophezulu, umsebenzi kufuneka yahlulwe ngezigaba ezibini. Okokuqala, lo ngokuyinyibilikisa yasuswa kule ngokuyinyibilikisa, wajoyina isikhongozeli ezaliswe ngamanzi metal. Ngenxa yoko, kukho zamathontsana emihle solder. Atshe, koko zasuka zanyibilika kwakhona, egubungele empahleni. Xa intsimbi inyibilikiswa ngokupheleleyo, kuba agalelwa ngumngundo ezizodwa. Emva Ukuqinisa i imivalo okanye tiles ezityikitywe ube ziziqwenga ezibhityileyo. Kuba ukusetyenziswa kweziveliso ze-aqingqiweyo kwi lathe kwi ucingo obhityileyo.

Iimpawu ngezakhiwo meltability medium

Zeziphi solders ekhaya isilivere? iimpawu zabo ziyafana nezo zililo ukuba kwimeko yamashishini. Siye wafumana amandla aphezulu brazing, nokumelana, libya indawo yokunyibilika, conductivity eliphezulu thermal. Ngexesha ukusebenza, Wawuzalisa ukwakhiwa isithuba yonke phakathi imiphezulu solder, inika umthungo anencasa ixesha elide. Ukuba ufuna ukwenza uphawu PSP-72 ingxubevange kubalulekile ukukhumbula ukuba kweziyobisi kwindawo lithium ukunyibilika ngobhedu lifinyele. Loo sisincoko ilungele ukuba brazing amalungu zentsimbi ezingamelanga zidibane umhlwa imichiza.

Ukulungiselela i solder ekhaya: iimpawu kunye algorithm

brazing Silver ekhaya ifuna inkqubo umva - uguqulelo etyhidiweyo kurhulumente eqinileyo. Okokuqala, kubalulekile ukunyibilika ngokupheleleyo isilivere, uze ke uthi lwayiwisela ku Ingus. Lo msebenzi yahlulwe ngezigaba ezithathu: eyimveliso amacephe - Foundry, i ukubhobhoza additive, makafakwe yeflawa ibhetshi, oluxonxiweyo, impahla ekrwada, uyibeka e Ingus.

Beka amacephe kwi emazantsi ibhokisi encinane yekhadibhodi, ngoko elibonakayo ezinkulu kancinane, ngoko wayisonga ngohlangothi ngecephe. Ke ngokomgangatho okroqiweyo, ikhadibhodi sheets. Umandlalo kufuneka ibe phakathi ukuphumeza isiphumo ezinqwenelekayo. inkqubo yokunyibilika solder ekhaya ingapheli, ngoko ube nomonde. batch yokuhlela lwenziwa kwi esikalini izacholo. Master kufuneka ezi zinto zilandelayo:

• nezacholo, isikali elektroniki;
• 20 g ezilahliweyo yesilivere iisampuli 916;
• isiliva scrap iisampulu 875;
• loqobo (12 grams);
• borax;
• solder metal;
• sokukhuphela igesi

Nebhetshi yonke yahlulwe ziimfumba eziliqela ka 18-20 grams. Mixed isilivere ezilahliweyo kunye iisampuli 875. Kuba lokunyibilikisa kufuna phantse 6 iigrem ezilahliweyo kunye 42% ecocekileyo. Magnet icocwe ukusuka ukungcola zentsimbi.

iisampulu 875 nithabathe isilivere nobhedu ukuze ukwenziwa solder, umlinganiselo kufuneka 4: 1 (amashumi amahlanu eerandi kwaye zifuna imali ezinkozo lobhedu ezintathu zesilivere). Kuba ekubhobhozeni wasebenzisa yeboraksi om-1 ukuya kwi-10 Okulandelayo, wenza uhlengahlengiso ilangatye. Asazi singacebisi umlilo kakhulu, oko kuya kukhokelela ekubeni ngokutshiswa isinyithi, kunokuba zinyibilike. Ngaphezu zisiza igesi ibekwa icephe. Kwinkqubo ngokunyityilikiswa yahluka umbala yesilivere, yiyo phantsi ezantsi.

Further Ingus ibekwe kufuphi lilangatye ebilandelwa. Kuba ezikumgangatho ophezulu zinyibilike waluqaba kuqala nge ngumthwebeba. Musa ukuvumela Ukupholisa baphele kunye isilungiseleli seglosi, kuya esilimaza iimpawu zobugcisa solder. metal ulwelo obuthululwayo kancinci esotha Ingus. Emva koko ke amanzi abandayo. Emva epheleleyo bar ukupholisa ukutsala kuyo, kule fomu sakujika. Asbestos okanye ikhadibhodi ukutyabeka ingasetyenziselwa 3-5, ebanjwe.

Ukulungiswa Stars

Beautiful imixhaka, nezacholo, namajikazi, neefolokhwe, neenkamba, iitreyi ezincinci ezenziwe ngesiliva ezihonjiswe ubomi babantu. Kodwa ngokuhamba kwexesha, iimveliso zesinyithi elinqabileyo phula phantsi, sifuna ukulungiswa kunye nokubuyiselwa. Ukuze enze loo msebenzi solder yesilivere ezifunekayo. Kuba 925 oko kunokwenziwa ngesandla, esebenzisa icebiso bejewellery abaqeqeshiweyo. Umsebenzi kufuneka ezi zibonelelo zilandelayo nezixhobo: ngelotha eliqhelekileyo kwaye engaphumi ekubunjweni solder, ezilahliweyo zesilivere. Inguqulelo elula indlela yokulungisa kwikhonkco eqwengiweyo - uyithabathe ibe othengisa. Kodwa uyakwazi ukujongana nengxaki kwaye nasekhaya ukuze wonge imali. Ukuze ngesandla soldered isilivere, kufuneka sifunde algorithm yezenzo, iindlela zeteknoloji, ukuze bafunde iimpawu ezibonakalayo zesilivere aluminium yayo.

Imithetho ngelotha Stars

Ukuze enze ezi zenzo kubalulekile ukuba ulwazi malunga neempawu physico-eekhemikhali eziphathekayo. Silver lokunyibilika - degrees 960 Celsius. Ukususela ngokombono bejewellery i-avareji. Umzekelo, enyibilikayo sobhedu kunokwenzeka kwi 1083ºS igolide linyibilike e 1063ºS.

Kuxhomekeka amacandelo ezibandakanywe zesilivere ziya kwahluka iqondo lobushushu. Ukuze ukuchonga ngokuchanekileyo iimpawu ingxubevange, kuyenzeka ukuba basebenzise kweencwadana zobugcisa. Ukuphawula solders zesilivere Russian ibandakanya ukulandelelana oonobumba kunye neenamba. Amanani agcwele ipesenti kwensimbi amanene kwi solder.

Yokulungisa imveliso yesilivere, kufuneka ukulungiselela i intsimbi ngelotha, ukucoca umphezulu. solder Silver ivumela, iijoyinti tight, ukumelana umhlwa. Xa nokulungisa izinto isicelo solder equlathe ngaphezu kwe-70 zesilivere ekhulwini, okanye solder yintlama okhethekileyo.

Ekhaya, ukuba bayilungise izacholo ezincinane aluminiyamu zesilivere efanelekileyo, izinc, ubhedu kunye isiqalelo esithambileyo esimhlophe. Eliphezulu "monki" iya kuba kokwakhiwa ilandelayo: isilivere iindawo 45, 25 - nangobhedu, 30 - zinc. Ukunyibilika amacandelo oluqhutywa eziko lingavakali zifuna ukubhobhoza. Lo mxube yahlaliswa echithwa a zeendawana, emva okupholisa, lidlule kumatshini lothuli ukufumana zizixwexwe. ubukhulu yabo kufuneka ngaphezu 0.5 mm. Kuba ngelotha ekhaya kwakufuneka semaphepheni ububanzi 1-3 mm. kuba ukudla Home for zesiliva akufuneki ukusebenzisa zililo equlethe isiqalelo esithambileyo esimhlophe. Le metal kubangela iingxaki zempilo ezinzulu. indawo ngelotha zibekwe ngasemoyeni, oxides kwakheka. Ukunqanda le meko, esetyenziswa umxhesho ekhaya isigcino (ukubhobhoza). Phezu inyibilikiswa le solder yesilivere kubalulekile ukulandela nokwabiwa efanayo yokumpompoza kumphezulu ngayo. Ukuba kukho ukuthandabuza izakhono nolwazi nemiqathango inkqubo ngelotha, kungcono ukuba uqhagamshelane othengisa yobungcali.

Akukhuthazwa ukuba zisetyenziswe kule zililo ekhaya equlathe isiqalelo esithambileyo esimhlophe, njengoko komphunga yena impilo iba nefuthe elibi. Ukuthintela inkqubo oxidative kunye nezinye abasabela elibi inokuba ukusebenzisa wampompoza (isigcino). Kubalulekile ukuba kubenge- isasazwe phezu komhlaba intsimbi.

isiphelo

brazing Silver ifuna izakhono ezizodwa ukususela inkosi kunye nesibindi. Isiphumo efunekayo kunokwenzeka kuphela xa ekhethiweyo kakuhle wampompoza, solder zesilivere. ngokungasebenzi yesilivere ezingafanelekanga ukulungiswa ekhaya, ukususela kwindawo yokunyibilika lingaphantsi kunolo izinto zibuyiselwe. Ayifanelekile ukusebenza kunye nokwenziwa ukuba ilingana ne loqobo zinyibilike index. Oku kuya kubangela ukuhamba ngexesha ukunyibilika le solder.
