Inkcazo
I-Flux: Ikhemikhali enokuthi incede kwaye ikhuthaze inkqubo ye-welding, kwaye inefuthe lokukhusela kwaye ithintele ukuphendula kwe-oxidation. I-Flux inokwahlulwa ibe yinto eqinileyo, engamanzi kunye negesi. Ikakhulu ibandakanya "ukuncedisa ukuqhubela ubushushu", "ukususa i-oxides", "ukunciphisa ukuxinana komphezulu wezinto ezidityanisiweyo", "ukususa amabala e-oyile kumphezulu wezinto ezidityanisiweyo, ukwandisa indawo ye-welding", kunye "nokuthintela i-reoxidation" . Phakathi kwale miba, eyona misebenzi mibini ibaluleke kakhulu yile: "ukususa i-oxides" kunye "nokunciphisa ukuxinana komphezulu wezinto ezidityanisiweyo".
Ukukhethwa kwe-flux Umsebenzi we-flux kukuphucula ukusebenza kwe-welding kunye nokwandisa ukuqina kwe-welding. I-Flux inokususa i-oksidi kumphezulu wesinyithi kwaye iyithintele ukuba ingaqhubeki ne-oxidize, iphucule umsebenzi we-solder kunye nesinyithi, ngaloo ndlela inyusa amandla okumanzisa kunye nokunamathela.
I-Flux ibandakanya i-asidi eqinile, i-asidi ebuthakathaka, i-neutral flux kunye nezinye iintlobo. Iintsholongwane ezisetyenziswa ngokuqhelekileyo kumbane zibandakanya i-rosin, isisombululo se-rosin, i-solder paste kunye neoli ye-solder, njl. I-solder paste kunye ne-oyile ye-solder ziyadla kwaye azinakusetyenziselwa ukuthengisa izinto ze-elektroniki kunye neebhodi zesekethe. Emva kwe-solder, i-solder paste eseleyo kunye neoli ye-solder kufuneka ihlambuluke. I-rosin kufuneka isetyenziswe njenge-flux xa ucofa izikhonkwane zamalungu. Ukuba ibhodi yesekethe eprintiweyo ifakwe kwisisombululo se-rosin, akukho flux efunekayo xa i-soldering amacandelo.
Kubavelisi, akukho ndlela yokuvavanya ukubunjwa kwe-flux. Ukuba ufuna ukwazi ukuba i-solvent ye-flux iyaguquguquka, unokulinganisa ngokulula ubunzima obuthile. Ukuba i-gravity ethile inyuka kakhulu, kunokugqitywa ukuba i-solvent iye yaguquka.
Xa ukhetha i-flux, kukho iingcebiso ezilandelayo zabavelisi:
Okokuqala, vumba ivumba ukuze ubone kwangaphambili ukuba luhlobo luni lwesinyibilikisi esisetyenziswayo. Ngokomzekelo, i-methanol inevumba elincinane kodwa ixutywe kakhulu, i-isopropyl alcohol inevumba elinzima, kwaye i-ethanol inevumba elimnandi. Nangona umthengisi angasebenzisa i-solvent exubeneyo, ukuba umthengisi uceliwe ukuba anike ingxelo yokuqulunqa, baya kubonelela ngokubanzi; nangona kunjalo, ixabiso le-isopropyl alcohol limalunga ne-3-4 amaxesha e-methanol. Ukuba ixabiso liyancipha kakhulu kunye nomthengisi, kunokuba nzima ukuthetha oko kungaphakathi
Okwesibini, misela isampuli. Le yeyona ndlela isisiseko yokuba uninzi lwabavelisi bakhethe i-flux. Xa uqinisekisa isampuli, umthengisi kufuneka acelwe ukuba anike ingxelo efanelekileyo yeparameter kwaye ayithelekise kunye nesampuli. Ukuba isampuli iqinisekisiwe Kulungile, ukuhanjiswa okulandelayo kufuneka kuthelekiswe neeparamitha zokuqala. Xa kusenzeka izinto ezingaqhelekanga, umxhuzulane okhethekileyo, ixabiso le-asidi, njl. njl. kufuneka lihlolwe. Ubungakanani bomsi owenziwe yi-flux kwakhona luphawu olubaluleke kakhulu.
Okwesithathu, imarike ye-flux ixutywe. Xa ukhetha, kufuneka ube nokuqonda okucacileyo kwemigangatho yemfundo yomthengisi. Ukuba kuyimfuneko, ungaya kumenzi ukuze ubone umzi-mveliso. Ukuba ngumenzi we-flux ongekho sikweni, uyoyika kakhulu le seti. Indlela yokusebenzisa i-flux Ngaphambi kokwazisa indlela yokusetyenziswa, makhe sithethe ngokuhlelwa kwe-flux. Inokwahlulwa ibe luluhlu lwe-non-polar flux. Le ithengiswa kwimarike ibizwa ngokuba "ioli ye-solder". Qinisekisa ukuba uyihlambulule emva kokusetyenziswa, ngaphandle koko kulula ukubola kunye nokonakalisa into edibeneyo.
Olunye uhlobo yi-organic series flux, enokukhawuleza ukubola kwaye ishiye iintsalela ezingasebenzi. Olunye uhlobo yi-resin esebenzayo series flux. Olu hlobo lwe-flux alunakugqwala, lukhusela kakhulu kwaye lunozinzo olude. Eyona isetyenziswa ngokuqhelekileyo kukongeza i-activator kwi-rosin flux.
Ngokuqhelekileyo, indlela yokusebenzisa i-aluminium flux ilula. Okokuqala, sula utywala kwi-weld ukususa amabala e-oyile, kwaye emva koko unokusebenzisa i-flux kumphezulu ukuba udityaniswe, kwaye ke unako ukuthunga. Kodwa kufuneka ukhumbule ukuyicoca emva kwe-welding, kwaye ubeke ingqalelo kukhuseleko ngexesha lokusetyenziswa, kwaye ungavumeli ukuba ungene emlonyeni, impumlo, umqala kwaye uqhagamshelane nolusu. Xa ingasetyenziswa, yitywine kwaye uyibeke kwindawo epholileyo nengena umoya.
Isitshixo kwiisekethe ze-soldering ezinemivalo ye-tin kukucoca indawo ye-soldering, ukufudumala kunye nokunyibilikisa i-rosin kwindawo yokuthungatha okanye ukusebenzisa i-flux kwizinto eziza kuthengiswa, kwaye emva koko usebenzise i-iron ye-soldering ukuyicoca kwaye uyibhekise kwinqanaba. ukuba ithengiswe. Ngokubanzi, i-rosin isetyenziselwa ukuthengisa izinto ezincinci, kwaye i-flux isetyenziselwa ukuthengisa izinto ezinkulu. I-rosin isetyenziswe kwiibhodi zeesekethe, kwaye i-flux isetyenziselwa i-solder-piece-piece.
