IiCarbides ezahlukeneyo

Nangona i-tungsten carbide idlala indima ebalulekileyo kwimarike yemizi-mveliso, ezinye ii-carbides ezininzi zikhona kumashishini ahlukeneyo. Kweli nqaku, uya kukwazi iintlobo ezahlukeneyo ze-carbides. Bazi:

1. I-Boron carbide;

2. I-silicon carbide;

3. I-tungsten carbide;

I-Boron carbide

I-Boron carbide yi-crystalline compound ye-boron kunye ne-carbon. Luhlobo lwemathiriyeli eveliswe ngokwenziwa enobunzima obuphezulu ukuze isetyenziswe ngokubanzi kwiimveliso ezirhabaxa nezinganxibiyo, imathiriyeli edityanisiweyo ekhaphukhaphu, kwaye ingasetyenziswa kwiintonga zolawulo zokuvelisa amandla enyukliya.

Njengempahla yoshishino, i-boron carbide ineepropati ezininzi. Inobulukhuni be-Mohs be-9 ukuya kwi-10, kwaye ikwayenye yezona zixhobo ezinzima kakhulu. Ngobunzima obuphezulu kunye noxinzelelo oluphantsi, i-boron carbide ingasetyenziselwa njenge-agent yokuqinisa i-aluminium emkhosini. Ukunganyangeki kwayo okuphezulu kwenza ukuba kube lula ukufumana izicelo njengezinto zemibhobho eqhumayo kunye nezitywina zokumpompa. I-Boron carbide ingasetyenziswa njenge-abrasive kwifom yomgubo kwi-abrading emihle yesinyithi kunye neemveliso ze-ceramic. Nangona kunjalo, ngeqondo eliphantsi le-oxidation ye-400-500 ° C, i-boron carbide ayikwazi ukumelana nobushushu bokugaya izixhobo ezilukhuni zentsimbi.

I-silicon carbide

I-silicon carbide yi-crystalline compound ye-silicon kunye ne-carbon. Yafunyanwa ngo-1891 ngumqambi waseMelika. Emva koko i-silicon carbide isetyenziswa njengento ebalulekileyo kwi-sandpapers, amavili okugaya, kunye nezixhobo zokusika. Kuze kube yilapho i-silicon carbide yoshishino yanamhlanje ifunyenwe ukuba isetyenziswe kwiindawo zokuxhathisa iimpompo kunye neenjini ze-rocket, njalo njalo.

Ngaphambi kokufunyanwa kwe-boron carbide, i-silicon carbide yayiyeyona nto inzima. Ikwanayo neempawu zokuqhekeka, ukuhanjiswa okuphezulu kwe-thermal, amandla obushushu obuphezulu, ukwandiswa kwe-thermal ephantsi, kunye nokuchasana nokusabela kweekhemikhali.

I-tungsten carbide

I-Tungsten carbide sesona sixhobo sisetyenziswa kakhulu kwishishini lanamhlanje, elibandakanya i-tungsten carbide powder kunye nenani elithile le-cobalt okanye i-nickel powder njenge-binder. I-Tungsten carbide yinto eshinyeneyo engwevu. Kwahlukile ukunyibilika kwindawo ephezulu yokunyibilika. I-Tungsten carbide inobunzima obuphezulu, ukumelana nokunxiba, ukuxhathisa impembelelo, ukuxhathisa ukothuka, kunye namandla kwaye inokusebenza ixesha elide. Kwaye i-tungsten carbide inokuveliswa kwiimilo ezahlukeneyo kunye neentlobo zeemveliso ze-tungsten carbide, ezifana namaqhosha e-tungsten carbide, i-tungsten carbide inserts, i-tungsten carbide rods, i-tungsten carbide strips, iibhola ze-tungsten carbide, i-tungsten carbide valves, kunye ne-tungsten carbide punch pins. Zisetyenziswa kakhulu kumashishini anamhlanje, afana nemigodi, igesi, ioli, ukusika, ukuvelisa, ukulawula ulwelo, njalo njalo.

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