Intsimi yesicelo se-tungsten

I-Tungsten eyaziwa ngokuba yi-wolfram, yikhemikhali enophawu lwe-W kunye nenombolo ye-athomu ngu-74. Sisinyithi esikhethekileyo esinoluhlu olubanzi lokusebenzisa ubuchwepheshe bale mihla. Intsimbi yeTungsten yintsimbi enzima kwaye enqabileyo. Inokufumaneka kuphela emhlabeni kwiikhompawundi zemichiza. Uninzi lweekhemikhali zayo ze-tungsten oxide kwaye uninzi lwemigodi ye-tungsten yafunyanwa eTshayina. Ngokukodwa kwiphondo laseHunan kunye neJiangxi. Ngenxa yendawo ephezulu yokunyibilika kwayo, ubunzima obuphezulu, ukumelana nokugqwesa okugqwesileyo, ukuhanjiswa kakuhle kombane, kunye nokuhanjiswa kwe-thermal, iye yaba yenye yezona zinto zibalulekileyo ezisebenzayo kushishino lwanamhlanje. Isetyenziswa kakhulu kwi-alloy, i-electronics, ikhemikhali, unyango, kunye nezinye iinkalo.

1. Kwintsimi ye-Industrial alloys

I-metallurgy yomgubo yindlela yokuvelisa iimveliso ze-tungsten sintered. I-tungsten powder iyona nto ibalulekileyo ekrwada kunye nesiqalo semveliso ye-tungsten mineral. Umgubo weTungsten wenziwa ngokurosa kunye nokufudumeza i-tungsten oxide kwiatmosfera yehydrogen. Ubunyulu, ioksijini, kunye nobungakanani bamasuntswana abaluleke kakhulu ekulungiseleleni umgubo we-tungsten. Inokuxutywa kunye nezinye izinto zomgubo ukwenza iindidi ezahlukeneyo ze-tungsten alloys.

I-tungsten esekwe kwi-carbide enesamente:

I-tungsten carbide ihlala isetyenziselwa ukuxuba kunye nezinye isinyithi ukunyusa ukusebenza kwayo. Umxube wesinyithi uquka i-cobalt, i-titanium, isinyithi, isilivere, kunye ne-tantalum. Isiphumo kukuba i-tungsten carbide-based cemented carbide inokumelana nokunxiba okuphezulu kunye neempawu eziphezulu zokuchasa. Zisetyenziswa kakhulu kwimveliso yokusika izixhobo, izixhobo zemigodi, umzobo wocingo uyafa, njl njl. Iimveliso ze-carbide ezisekelwe kwi-tungsten ezisekelwe kwi-carbide zikhethwa nangaphezu kwensimbi engenasici ngenxa yobunzima babo obumangalisayo kunye nokuchasana nokunxiba kunye nokukrazula. Ingasetyenziswa ngokubanzi kwizicelo zokwakha zorhwebo, izinto zombane, ukwenziwa kweegiya zamashishini, izixhobo zokukhusela iradiation, kunye neshishini lokubhabha.

Ingxubevange yobushushu kunye ne-alloy ekwazi ukumelana nokunxitywa:

Indawo yokunyibilika ye-tungsten yeyona iphakamileyo kuzo zonke iintsimbi, kwaye ukuqina kwayo kukwesibini kwidayimane. Ngoko ke isoloko isetyenziselwa ukuvelisa i-alloys ekwazi ukumelana nobushushu kunye nokunxiba. Ngokomzekelo, ii-alloys ze-tungsten kunye nezinye iintsimbi eziphikisayo (i-tantalum, i-molybdenum, i-hafnium) zihlala ziveliswa kwiindawo eziphakamileyo ezifana ne-nozzles kunye neenjini zeerokethi. Kwaye i-alloys ye-tungsten, i-chromium, kunye nekhabhoni zihlala zisetyenziselwa ukuvelisa amandla aphezulu kunye namalungu angaguqukiyo, njengeevalvu zeenjini zenqwelomoya, amavili omoya, njl.

2. Kwintsimi yeekhemikhali

Iikhompawundi zeTungsten ziqhele ukusetyenziswa ukuvelisa iintlobo ezithile zeepeyinti, ii-inki, izinto zokuthambisa, kunye nezinto zokuthambisa. Ngokomzekelo, i-tungsten oxide enombala wobhedu isetyenziselwa ukupeyinta, kwaye i-calcium okanye i-magnesium tungsten isetyenziswa ngokuqhelekileyo kwi-phosphors.

3. Kwintsimi yomkhosi

Iimveliso zeTungsten zisetyenziselwe ukubuyisela ilothe kunye nemathiriyeli ye-uranium ephelelweyo ukwenza ii-bullet warheads ngenxa yeempawu zazo ezingenatyhefu kunye nokhuseleko lokusingqongileyo, ukuze kuncitshiswe ungcoliseko lwezixhobo zomkhosi kwindalo esingqongileyo. Ukongeza, i-tungsten inokwenza umlo wokulwa weemveliso zomkhosi uphakame ngenxa yokuqina kwayo okuqinileyo kunye nokumelana nobushushu obuphezulu.

I-Tungsten ayinakusetyenziswa kuphela kule mimandla ingasentla kodwa nakwindlela yokuhamba, amandla eathom, ukwakha iinqanawa, ishishini leemoto, kunye neminye imimandla. Ukuba unomdla kwi-tungsten okanye unemibuzo malunga nayo. Nceda uqhagamshelane nathi ngoku.
