Yini Okufanele Siyazi Nge "Tinning Rods"

Ukulungiselela kanye nezidingo zekhwalithi zezinti zokuthayela/iziqephu

I-tin rod, njengoba igama lisho ukuthi i-rod solder, ibizwa ngokuthi imboni ye-tin rod. Ikakhulukazi esetshenziselwa i-wave soldering kanye nokucwiliswa kwe-welding, okwamanje ukusetshenziswa okukhulu kwezinhlobonhlobo ze-solder electronic; inani elincane liphinde lisetshenziswe ekushiseni ilangabi noma ukushisela insimbi ye-soldering yezingxenye ezinkulu zesakhiwo kanye nokushisela okude. Iyinto ebaluleke kakhulu nebalulekile yokuxhuma kuyo yonke imikhiqizo kagesi kanye nekagesi futhi ukusetshenziswa komhlaba wonke ngonyaka kungamathani ayi-100,000.

Inqubo yokulungiselela i-tin strip ilula, kufaka phakathi i-batching, ukuncibilika nokuphonsa, futhi izinga le-oxidation kanye nokuqukethwe kokungcola kwensimbi nokungewona okwensimbi kulawulwa ngokuqinile. Izinga lokushisa elincibilikayo kanye nezinga lokushisa lokuphonsa kunethonya elikhulu kwikhwalithi yethini. Ukulungiswa kwama-tin strips kulula futhi umkhawulo wezobuchwepheshe uphansi, ngakho-ke ukuncintisana kushube kakhulu. Intengo yamanje yengeza kuphela imali encane yokucubungula ezindlekweni zezinto zokusetshenziswa. Uma intengo yezinto ezingavuthiwe i-tin ishintshashintsha kakhulu esikhathini esifushane, inzuzo encane ingase isulwe, noma ngisho nokulahlekelwa.

Izidingo eziyinhloko zekhwalithi ye-tin strip yilezi ezilandelayo:

(1) Ubuso bomucu kathayela bushelelezi;

(2) Uketshezi oluhle kanye nokumanzisa ngesikhathi sokushisela;

(3) Izakhiwo ezinhle zemishini;

(4) Inhlanganisela ye-solder ekhanyayo;

(5) Izinsalela ze-oxidation encane.

Amaphutha avamile ebusweni be-tin strip amabala ezimbali namabhamuza. Lezi zinkinga zibangelwa inqubo yokukhiqiza kanye nokusetshenziswa kwesikhunta. Isibonelo, ayikho indawo yokugebha ngesikhathi sokukhiqiza, uhlelo lokupholisa alulungile, futhi isikhunta asibushelelezi, okuzoholela ezinkingeni ezingenhla. Imbangela yokuqhuma kwamabhamuza ihlobene nesimo sezulu enziwe ngaso. Abasebenzi bokukhiqiza bathatha ibha yethini, bangasisebenzisi ngokuqondile isandla, umswakama osesandleni uzothinta ukukhanya kwebha yethayela, inguqulo yebha ye-tin yokusetshenziswa okungcono kakhulu kwephepha lepulasitiki, bobabili bangabona ukukhanya, hhayi ukumanzi. Uma isikhathi sokugcina siside noma indawo yokugcina imanzi kakhulu, kuzoba nongqimba lwe-oxide ebusweni bomucu wethini, okuzokwenza nokukhanya kwe-tin strip kufiphele, kodwa kunomphumela omncane emphumeleni wokusetshenziswa. .

Izigaba ze-tin strips:

Amapheshana kathayela ahlukaniswa ngokuvikelwa kwemvelo, okuhlanganisa amapheshana kathayela omthofu namapheshana angenawo umthofu.

Okwamanje, imichilo yamathini angenawo umthofu asetshenziswa kakhulu yilena: umucu kathayela we-tin copper ongenawo umthofu (Sn99.3Cu0.7), i-tin silver copper-free free tin strip (Sn96.5Ag3.0Cu0.5), 0.3 silver lead- umucu kathayela wamahhala (Sn99Ag0.3Cu0.7), umucu kathayela ongenayo umthofu wohlobo lokushisa eliphezulu (SnSb).

I-electrode ye-lead tin evame ukusetshenziswa kakhulu ihlanganisa: ibha ye-solder engu-63/37 (Sn63/Pb37), ibha ye-solder engu-60/40 (Sn60/Pb40) kanye nebha yokushisa ephezulu (ama-degree angu-400 ngaphezu kokushisela).

Ngaphezu kwezakhi eziyinhloko ze-tin, i-lead, ithusi, isiliva, ngokuvamile iqukethe inani elincane lezinye izakhi, njenge-nickel, i-antimony, i-bismuth, in, umhlaba ongavamile njalonjalo.

Lezi zakhi ezincane ze-alloy ku-tin strip zinethonya elikhulu ezintweni ezibonakalayo nezomshini zomucu we-tin: i-bismuth inganciphisa izinga lokushisa elincibilikayo le-tin strip futhi ithuthukise indawo yokumanzisa nokusabalalisa, kodwa i-bismuth eningi izonciphisa impilo yokukhathala kanye ne-plasticity ye-solder. amalunga, futhi inani elifanele le-bismuth lingaba ngu-0.2 ~ 1.5%. I-Ni ingathuthukisa izakhiwo zemishini nempilo yokukhathala yamalunga e-solder ngokushintsha i-microstructure nokucwenga okusanhlamvu. Eklanyweni ehlelekile yokwakheka kwamakhemikhali, umklami ngokusobala uthemba ukuthi umugqa we-tin ungafinyelela ibhalansi efanele ezicini ezihlukahlukene zokusebenza, njengokusebenza kokushisela, izinga lokushisa elincibilikayo, amandla, ipulasitiki kanye nempilo yokukhathala, njll.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGAXHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi kwaleli khasi.
