Yintoni ekufuneka siyazi malunga ne "Tinning Rods"

Ukulungiswa kunye neemfuno zomgangatho weentonga/imicu yokutofa

Intonga yenkcenkce, njengoko negama lithetha ukuba i-solder yentonga, ibizwa ngokuba kushishino lwentonga. Ikakhulu isetyenziselwa ukuthengiswa kwamaza kunye nokuntywiliselwa kwe-welding, okwangoku lolona setyenziso lukhulu lweentlobo ze-solder ze-elektroniki; isixa esincinci sikwasetyenziselwa ukutshisa idangatye okanye ukuwelda intsimbi yeendawo ezinkulu zesakhiwo kunye neewelds ezinde. Yeyona imathiriyeli ibalulekileyo nebalulekileyo yokudibanisa kuzo zonke iimveliso zombane kunye nezombane kwaye ukusetyenziswa kwehlabathi ngonyaka malunga neetoni eziyi-100,000.

Inkqubo yokulungiselela i-tin strip ilula, kubandakanywa ukuxutywa, ukunyibilika kunye nokuphosa, kunye neqondo le-oxidation kunye nomxholo wesinyithi kunye nokungcola okungeyona isinyithi kulawulwa ngokungqongqo. Ubushushu bokunyibilika kunye nobushushu bokuphosa bunempembelelo enkulu kumgangatho wetoti. Ukulungiswa kwemigca ye-tin kulula kwaye umda wezobugcisa uphantsi, ngoko ke ukhuphiswano lunzima kakhulu. Amaxabiso akhoyo ongeza kuphela umrhumo omncinci wokusetyenzwa kwiindleko zemathiriyeli ekrwada. Xa ixabiso lezinto zenkcenkcesha liguquguquka kakhulu kwixesha elifutshane, inzuzo encinci inokupheliswa, okanye ilahleko.

Iimfuno eziphambili zomgangatho we-tin strip zezi zilandelayo:

(1) Umphezulu wenkcenkce ugudile;

(2) Ukumanzi kakuhle kunye nokumanzisa ngexesha le-welding;

(3) Iimpawu ezilungileyo zoomatshini;

(4) I-solder eqaqambileyo;

(5) Intsalela ye-oxidation encinci.

Iziphene eziqhelekileyo kumphezulu we-tin strip ngamachokoza eentyatyambo kunye namaqamza. Ezi ziphene zibangelwa yinkqubo yokuvelisa kunye nokusetyenziswa kwe-molds. Ngokomzekelo, akukho ndawo yokukrazula ngexesha lokuvelisa, inkqubo yokupholisa ayilungile, kwaye i-molds ayilungile, okuya kubangela iingxaki ezingentla. Unobangela wokugqabhuka kwamadyungudyungu unxulumene nemozulu eyenziwe kuyo. Abasebenzi bemveliso bathatha i-tin bar, musa ukusebenzisa ngokuthe ngqo isandla, ukufuma kwisandla kuya kuchaphazela ukuqaqamba kwe-tin bar, inguqu ye-tin bar yolona setyenziso lungcono lwephepha leplastiki, bobabini banokubona ukukhanya, kwaye akukho manzi. Xa ixesha lokugcina lide okanye indawo yokugcina imanzi kakhulu, kuya kubakho umaleko we-oxide phezu komphezulu we-tin strip, oya kwenza ukuba ukukhanya kwe-tin strip kuphele, kodwa kunempembelelo encinci kwisiphumo sokusetyenziswa. .

Ulwahlulo lwemicu yetoti:

Imicu yenkcenkce ihlelwa ngokokhuseleko lwendalo esingqongileyo, kuquka imicu yetoti enelothe kunye nemicu yetoti engenalothe.

Okwangoku, imicu yetoti engenalothe esetyenziswa ngokuqhelekileyo zezi: i-tin copper-free tin strip (Sn99.3Cu0.7), i-tin strip ye-tin esiliva yobhedu engenalothe (Sn96.5Ag3.0Cu0.5), i-0.3 yesilivere ekhokelayo- free tin strip (Sn99Ag0.3Cu0.7), uhlobo lobushushu eliphezulu lead-free tin strip (SnSb).

I-electrode ye-tin esetyenziswa ngokuqhelekileyo ibandakanya: 63/37 ibha ye-solder (Sn63 / Pb37), ibha ye-solder ye-60/40 (Sn60 / Pb40) kunye ne-bar ye-solder ephezulu yokushisa (ama-400 degrees ngaphezu kwe-welding).

Ukongeza kwizinto eziphambili ze-tin, ilothe, ubhedu, isilivere, zihlala zinenani elincinci lezinye izinto, njenge-nickel, i-antimony, i-bismuth, in, umhlaba onqabileyo njalo njalo.

Ezi zinto zincinci ze-alloy kwi-tin strip zinempembelelo enkulu kwizinto ezibonakalayo kunye nezomatshini ze-tin strip: i-bismuth inokunciphisa ubushushu obunyibilikayo be-tin strip kwaye iphucule ipropathi yokumanzisa kunye nokusabalalisa, kodwa i-bismuth eninzi iyakunciphisa ubomi bokudinwa kunye neplastiki ye-solder. amalungu, kunye nemali efanelekileyo ye-bismuth malunga ne-0.2 ~ 1.5%. I-Ni inokuphucula iimpawu zoomatshini kunye nobomi bokudinwa kwamalungu e-solder ngokuguqula i-microstructure kunye nokucoca ingqolowa. Kuyilo olucwangcisiweyo lokwakheka kweekhemikhali, ngokuqinisekileyo umyili unethemba lokuba umtya wetin unokufezekisa ulungelelwaniso olufanelekileyo kwimiba eyahlukeneyo yokusebenza, njengokusebenza kwe-welding, ubushushu obunyibilikayo, amandla, iplastiki kunye nobomi bokudinwa, njl.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL ezantsi kweli phepha.
