I-tungsten carbide strip ngokuyinhloko yenziwe nge-WC tungsten carbide kanye ne-Cobalt powder exutshwe ngendlela ye-metallurgical by pulverization, ukugaya ibhola, ukucindezela nokufaka i-sintering, izingxenye eziyinhloko ze-alloy yi-WC ne-Co, okuqukethwe kwe-WC ne-Co ekusetshenzisweni okuhlukene kwe-tungsten carbide strip. akufani, futhi ububanzi bokusetshenziswa bubanzi kakhulu.
Enye yezinto ezisetshenziswa kakhulu ze-tungsten carbide strips, ibizwa ngokuthi yi-rectangular shape yamapuleti (noma izikwele), eyaziwa nangokuthi i-tungsten carbide strip/plates. I-tungsten carbide strip inobulukhuni obuhle kakhulu, ukumelana nokugqokwa okuhle, i-modulus enwebekayo ephezulu, amandla okucindezela aphezulu, ukuzinza okuhle kwamakhemikhali (i-asidi, i-alkali, ukumelana ne-oxidation lokushisa eliphezulu), ukuqina komthelela ophansi, i-coefficient ephansi yokwandisa, ukuqhutshwa kwe-thermal kanye nogesi okufana ne-iron kanye nokuqina kwayo. ama-alloys.
Yiziphi izizathu ze-desolderingye-tungsten carbide strips? I-Chuangrui carbide izophendula ngokulandelayo:
(1) Indawo egandayayo ye-tungsten carbide ayigaywa ngesanti noma iphucuziwe ngaphambi kokushiselwa, futhi ungqimba lwe-oxide endaweni yokubhula yehlisa umphumela wokumanzisa wensimbi yokubhula futhi yenza buthaka amandla okubopha weld.
(2)I-Desolderingizokwenzeka futhi lapho i-agent yokubhoboza ingakhethiwe futhi isetshenziswe ngendlela engafanele, isibonelo, lapho i-borax isetshenziswa njenge-agent ye-brazing, i-borax ayikwazi ukudlala ngokuphumelelayo indima ye-deoxidizing ngoba i-borax iqukethe umswakama owengeziwe, futhi impahla yokubhoboza ayikwazi ukumanziswa kahle. ebusweni obune-brazed, futhidesolderingokwenzekayo.
(3) Izinga lokushisa elilungile lokubhokoza kufanele libe ngu-30 ~ 50 °C ngaphezu kwendawo yokuncibilika yensimbi egandayo, futhidesolderingkuzokwenzeka uma izinga lokushisa liphezulu kakhulu noma liphansi kakhulu. Ukushisa kakhulu kungabangela i-oxidation ku-weld. Ukusebenzisa i-zinc brazing metal kuzonikeza i-weld umbala oluhlaza okwesibhakabhaka noma omhlophe. Lapho izinga lokushisa lokushisa liphansi kakhulu, kuzokwakhiwa i-weld eqinile, futhi ingaphakathi le-weld lizohlanganiswa ne-porosity kanye ne-slag inclusions. Lezi zimo ezimbili ezingenhla zizonciphisa amandla e-weld, futhi kulula ukuyi-deweld uma ibukhali noma isetshenziswa.
