Yintoni na ngelotha kweetyhubhu zobhedu

Ngelotha - inkqubo uqhagamshelwano lweziqalelo ezenziwe ngezinto ezahlukeneyo, ngokuthi unike solder phakathi kwabo. Ukongeza, le nkcazelo iye indawo yokunyibilika ngaphantsi koko ezinye iindawo. Olo tyando Isetyenziswa ngokubanzi ndlela bond kakhulu ezikumgangatho ophezulu. Brazing zokutyubhisha ubhedu ukuba sandise ubomi compound enjalo, beentanda yayo uphawu phantsi koxinzelelo, ukuqinisekisa ukumelana eliphezulu ukuya umhlwa.

Phambi kokuba uqale umsebenzi wakho, kungakuhle ukuba baqhelane ngeekhomponenti asisiseko odolo yazo ukuthintela imbonakalo bugs ezingafunekiyo uze ekugqibeleni uqhagamshelwano olusemgangathweni elungileyo.

Wenza ngelotha sobhedu kwemibhobho kunye solder ethambileyo okanye nzima. Le ezibonakalayo kuqala lisetyenziswa kwi lobushushu malunga 425 ° C, yaye iqondo yesibini kuvumelekile besukelana 560 ° C. Ukumisela uhlobo solder kuxhomekeke kwimali zekopolo nezinye izinto ezifumaneka kumafa yayo. Kwimeko apho solder for ngelotha ityhubhu ubhedu iqulethe zesilivere, iqondo layo ukunyibilika kufuneka incitshiswe.

Ukuze ufumane uqhagamshelwano olusemgangathweni elungileyo, kungcono ukuba kusetyenziswe izinto yobhedu-phosphor, kodwa ingongoma yabo yokunyibilika kuthelekiswa isilivere iphezulu kakhulu. Ngokuba nobhedu-yobhedu nobhedu-zobhedu izinto meltable kusetyenziswa ithende for ngelotha imibhobho yobhedu. ukusetyenziswa kwayo kulingana ngexabiso zabo ngomatshini amacandelwana phambi nkqubo, nto leyo ukunqanda ukuvela kukho umboniso oxide, nto leyo ibaluleke kakhulu kule nkqubo. Ngokubanzi ukubhobhoza isetyenziswa ukuba uhlobo paste, apho ngelotha lemibhobho sobhedu siya kuba lula kakhulu.

Ukwenzela ukuphepha iimpazamo iindawo ezimbaxa, ke kwakhona kufuneka bathobele imithetho ethile. Umchiza kufuneka lingadlulanga umenshaetsya idangatye, nto leyo idala ukufudumeza ubuninzi. Kuyimfuneko ukuba enze bamafutha kwemiphezulu yesinyithi. Izikhewu phakathi izakhi kwizikhundla zawo kufuneka lutshekishwe ngononophelo.

Brazing zokutyubhisha copper iquka isicelo evela ngaphandle izixa compound encinane ngobhobhozo. Kwakhona, indawo le ukuba ukufudumala ngokufanayo kwiqondo lobushushu efunekayo. Emva koko, lo solder ukuze mayifakwe kwi ezimbaxa kubenge- yasasazwa kulo ngokuthi brazing itotshi. Xa uhlobo otyhidiweyo, kuya kungena kwicala isiphambuka, leyo itshiswa ngakumbi.

Ekugqityweni ngelotha, iintsalela ngobhobhozo kufuneka isuswe. Kakhulu kubalulekile font eyodwa imithetho eziphambili: umjikelo ubushushu kufuneka xesha lide kakhulu, yaye nobushushu nakanye ngaphandle kule nkqubo. Ngaphezu koko, kuyimfuneko ukuba umoya ngokwaneleyo ukuthintela ziyingozi kakhulu umzimba umsi equlathe isiqalelo esithambileyo esimhlophe, umphunga.

Ukuthobela iingcebiso ngasentla ziya lula kakhulu ekwenziweni komsebenzi, ukonga ixesha kunceda ukufezekisa iziphumo ezinqwenelekayo.
