I-Mica Powder yi-mineral powder eguquguqukayo eyenziwe ngokuyintloko yi-aluminium silicate minerals, eneempawu ezifana nokufakelwa kombane, ukumelana nobushushu, kunye nokuzinza kweekhemikhali. Eyona nto iphambili kwi-mica powder yi-potassium aluminium silicate enesakhiwo esikhethekileyo sekristale esiqhekekileyo, ngelixa ikwanazo nezixa ezincinci zokungcola ezifana ne-iron, i-magnesium, kunye ne-sodium. Iimpawu ezizodwa zomzimba nezekhemikhali ze-Mica Powder zenze ukuba ibe yinto engabalulekanga kumashishini ahlukeneyo kwihlabathi liphela, kunye nezicelo eziquka ubunjineli bombane, ii-coating, izinto zokuthambisa, kunye nemveliso ephucukileyo.

1. Ukwenziwa koMgquba weMica: Ummangaliso weJografi owadalwa luQhoko loMhlaba nexesha

Eyona nto iphambili kwi-mica powder yendalo ziiminerali ze-mica ezenziwe nzulu ngaphakathi kolusu loMhlaba. Ngexesha leenkqubo zejoloji, i-magma etyebileyo kwi-aluminium kunye nee-hydrothermal fluids ziyasebenzisana phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo. Kwiminyaka emininzi edlulileyo, ezi zinto ziyaqina zibe yi-phyllosilicate yesakhiwo se-mica esahlukileyo, senza i-basal cleavage egqibeleleyo evumela ukwahlukana kube ngamaphepha amancinci, acacileyo. I-synthetic mica yenziwa ngokudibanisa okuphantsi kobushushu obuphezulu kwesanti ye-quartz, i-aluminium oxide, kunye nezinye izinto eziluhlaza, okwenza iikristale zokwenziwa ezinobunyulu obuphuculweyo kunye nokusebenza. Ngexesha lokucubungula, i-mica iyagaywa ibe ziinxalenye ezahlukeneyo zobukhulu—ukusuka kwii-coarse flakes (6-10 mesh) ukuya kwi-ultrafine powder (1250 mesh)—ngaloo ndlela ibeka isiseko sezicelo ezahlukeneyo ze-mica powder.

Namhlanje, umgubo we-mica osemgangathweni ophezulu uveliswa kwihlabathi liphela. Iindawo eziphambili zendalo ezivelisa i-mica ziquka iIndiya, iTshayina, iRashiya, kunye ne-United States. ETshayina, amaziko okucubungula agxile kwimveliso ye-mica eyomileyo, emanzi, kunye neyokwenziwa. Ezi mveliso zahlukile kwiindlela zokucubungula kunye namanqanaba omgangatho (ezihlelwe njenge-mica eyomileyo, i-mica emanzi, i-sericite mica, i-synthetic mica, i-pearlescent mica, i-golden mica, kunye ne-black mica), kodwa zonke zigcina iimpawu eziphambili ze-mica powder—ubushushu bombane obuhle kakhulu, uzinzo lobushushu, kunye ne-platy particle morphology evela kwisakhiwo sekristale esinomgangatho owahlukileyo.

2. Iimpawu eziphambili zeMica Powder: Kutheni imangalisa kangaka?

Ukusebenza kakuhle kwe-mica powder kuvela kwisakhiwo sayo esikhethekileyo sekristale kunye nokwakheka kwayo kweekhemikhali.

Ukufakwa kombane okugqwesileyo: I-Mica inesinye sezona zibalo ziphezulu zamandla e-dielectric phakathi kweeminerali zendalo (ukuya kuthi ga kwi-150-200 kV/mm), nto leyo eyenza ukuba ibe sisixhobo sokukhusela umbane esibalaseleyo kwizicelo ze-high-voltage kunye nezixhobo ze-elektroniki.

Ukumelana nobushushu okubalaseleyo: I-Mica ihlala izinzile kumaqondo obushushu afikelela kwi-600-800°C, kwaye amanye amanqanaba okwenziwa amelana ne-1000°C. Olu zinzo lobushushu luvumela ukusetyenziswa kwiindawo ezinobushushu obugqithisileyo ngaphandle kokuwohloka.

Ukungasebenzi kakuhle kweekhemikhali: I-Mica izinzile ngokweekhemikhali, imelana nee-asidi, ii-alkali, kunye nezinyibilikisi, ayinabungozi, kwaye inobuhlobo nokusingqongileyo. Ayisebenzi lula kwizinto ezininzi, iqinisekisa ukhuseleko kunye nokuthembeka kwiindlela ezahlukeneyo zokusebenza.

Ukucoca okugqibeleleyo kweBasal kunye nolwakhiwo oluqhekekileyo: Ulwakhiwo olukhethekileyo oluneeleya luvumela i-mica ukuba yahlulwe ibe ngamaphepha amancinci, aguquguqukayo anemilinganiselo ephezulu yobukhulu (ububanzi ukusuka kwi-15:1 ukuya kwi-80:1), enika iipropati zokuthintela, ukuqinisa, kunye nokugubungela umphezulu.

Ukuqhuba okuphantsi kobushushu: I-Mica ibonelela ngobushushu obuhle kakhulu ngelixa igcina ubushushu bombane, indibaniselwano enqabileyo exabisekileyo kwiindlela zokusetyenziswa kobushushu nombane.

Ukumelana nemozulu kunye nokuzinza kwe-UV: I-Mica ibonakalisa imisebe ye-ultraviolet kwaye imelana nemozulu embi, igcina ukusebenza kwayo kwiimeko zangaphandle nezinzima zendalo.

Iimpawu zokuthambisa kunye ne-Anti-Stick: Imiphezulu egudileyo neqhekekileyo inciphisa ukungqubana kwaye ithintele ukunamathela, iluncedo ekugqumeni nasekusetyenzisweni kokubumba.

Ezi mpawu zisebenza ngokubambisana, nto leyo eyenza umgubo we-mica ube yinto esetyenziswa kakhulu. Ingasetyenziswa njengesigqubuthelo sombane, isizalisi sokuqinisa, i-pigment yesithintelo, icandelo elimelana nobushushu, okanye isongezo esisebenzayo ukuhlangabezana neemfuno ezahlukeneyo zomsebenzi wemizi-mveliso eyahlukeneyo.

Umgubo weMica usetyenziswa ngokubanzi kwaye udityaniswe nzulu kuzo zonke iindawo zoqoqosho lwelizwe, udlala indima engenakutshintshwa kubunjineli bombane, ukuvelisa, ukwakha, kunye neemveliso zabathengi.
