Ama-Carbides ahlukahlukene

Yize i-tungsten carbide idlala indima ebalulekile emakethe yezimboni, amanye ama-carbide amaningi akhona ezimbonini ezahlukahlukene. Kulesi sihloko, uzokwazi izinhlobo ezahlukene ze-carbides. Kunjalo:

1. I-Boron carbide;

2. I-silicon carbide;

3. Tungsten carbide;

I-Boron carbide

I-Boron carbide iyinhlanganisela ye-crystalline ye-boron ne-carbon. Iwuhlobo lwempahla ekhiqizwe ngokwenziwa enobulukhuni obuphezulu ukuze isetshenziswe kabanzi emikhiqizweni eqhumayo nengagugi, izinto eziyinhlanganisela engasindi, futhi ingasetshenziswa ezindongeni zokulawula ukukhiqiza amandla enuzi.

Njengempahla yezimboni, i-boron carbide inezakhiwo eziningi. Inobulukhuni be-Mohs obungu-9 kuya ku-10, futhi ingenye yezinto ezisetshenziswayo ezinzima kakhulu. Ngobunzima obunjalo obuphezulu kanye nokuminyana okuphansi, i-boron carbide ingasetshenziswa njenge-ejenti yokuqinisa i-aluminium ezempi. Ukumelana nokugqokwa kwayo okuphezulu kwenze kwaba nokwenzeka ukuthola izinhlelo zokusebenza njengezinto zemibhobho eqhumayo eqhumayo kanye nezimpawu zokupompa. I-Boron carbide ingasetshenziswa njenge-abrasive efomini eliyimpushana ekuhuqweni okuhle kwemikhiqizo yensimbi neye-ceramic. Nokho, ngezinga lokushisa eliphansi le-oxidation elingu-400–500° C, i-boron carbide ayikwazi ukumelana nokushisa kwezinsimbi zamathuluzi eziqinile zokugaya.

I-silicon carbide

I-silicon carbide iyinhlanganisela ye-crystalline ye-silicon ne-carbon. Yatholwa ngo-1891 ngumsunguli waseMelika. Khona-ke i-silicon carbide isetshenziswa njengento ebalulekile yama-sandpaper, amasondo okugaya, namathuluzi okusika. Kuze kube yilapho imboni yesimanje i-silicon carbide itholakala ukuthi isetshenziswa ezingxenyeni ezingakwazi ukumelana namaphampu ngisho nezinjini zamarokhethi, njalo njalo.

Ngaphambi kokutholwa kwe-boron carbide, i-silicon carbide yayiyinto enzima kakhulu. Iphinde ibe nezici zokuphuka, ukuqhutshwa kokushisa okuphezulu, amandla okushisa aphezulu, ukunwetshwa okuphansi kokushisa, nokumelana nokusabela kwamakhemikhali.

I-tungsten carbide

I-Tungsten carbide iyithuluzi elisetshenziswa kakhulu embonini yesimanje, equkethe i-tungsten carbide powder kanye nenani elithile le-cobalt noma i-nickel powder njenge-binder. I-Tungsten carbide iyinto eminyene ngokumpunga okukhanyayo. Kuhlukile ukuncibilika ngephuzu eliphezulu lokuncibilika. I-Tungsten carbide inobulukhuni obuphezulu, ukumelana nokugqoka, ukumelana nomthelela, ukumelana nokushaqeka, namandla futhi ingasebenza isikhathi eside. Futhi i-tungsten carbide ingenziwa ibe yizinhlobo ezahlukene kanye nezinhlobo zemikhiqizo ye-tungsten carbide, njengezinkinobho ze-tungsten carbide, ukufaka i-tungsten carbide, izinduku ze-tungsten carbide, imichilo ye-tungsten carbide, amabhola e-tungsten carbide, ama-tungsten carbide valves, nezikhonkwane ze-tungsten carbide punch. Zisetshenziswa kakhulu ezimbonini zanamuhla, njengezimayini, igesi, uwoyela, ukusika, ukukhiqiza, ukulawula uketshezi, njalonjalo.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
