Libolo tsa Alumina tsa ho Sila
Jwalo ka sesebediswa sa ho sila sa ceramic se sebetsang hantle haholo,Libolo tsa Alumina tsa ho SilaLi entsoe ka mokhoa o ikhethang oa ho sila, ho sila le ho qhalakanya lits'ebetso ho pholletsa le makala a fapaneng a indasteri. Li entsoe ka aluminium oxide e hloekileng haholo (Al₂O₃) e le karolo ea mantlha le theknoloji e tsoetseng pele ea ho sila ea letsopa, libolo tsena li hlahella ka ho ba thata ha tsona ho feta tekano, ho hanyetsa ho tsofala le botsitso ba lik'hemik'hale, e leng se etsang hore e be khetho ea pele bakeng sa ts'ebetso e sebetsang hantle le e nepahetseng ea thepa.
1. Tlhophiso ho latela Dikahare tsa Alumina
(1) Libolo tsa Aluminium tse Mahareng (60%-65% Al₂O₃):Khetho e theko e tlase bakeng sa lits'ebetso tse akaretsang tsa ho sila. E loketse lisebelisoa tsa ho sila tse nang le bothata bo tlase, joalo ka seretse sa mashala, manyolo le liminerale tse tloaelehileng. E loketse bareki ba batlang ts'ebetso e leka-lekaneng le litharollo tse theko e tlase.
(2) Libolo tsa Aluminium tse Mahareng-Holimo (75%-80% Al₂O₃):Ho hanyetsa ho tsofala ho ntlafetseng ha ho bapisoa le libolo tsa aluminium tse mahareng. E sebelisoa haholo ho sileng thepa e tala ea letsopa, thepa ea kaho, le lihlahisoa tsa lik'hemik'hale tse sa senyeheng haholo. Khetho e feto-fetohang bakeng sa ho sila indastering e mahareng.
(3) Libolo tsa Aluminium e Phahameng (≥90% Al₂O₃):Sehlopha sa boleng bo holimo se nang le ts'ebetso e felletseng e phahameng. Se arotsoe hape ka lihlopha tse ka tlase tsa 90-ceramic, 92-ceramic, 95-ceramic, le 99-ceramic. Har'a tsona, libolo tsa 92-ceramic ke tsona tse tsebahalang haholo ka lebaka la tekano ea tsona e ntle ea ts'ebetso le litšenyehelo, tse sebelisoang haholo ho sileng hantle ha li-glaze tsa ceramic, thepa ea elektroniki le lisebelisoa tse tala tsa lik'hemik'hale tse hloekileng haholo. Libolo tsa 99-ceramic, tse nang le alumina e ngata ka ho fetisisa, li etselitsoe ho sila ka nepo haholo liindastering tsa maemo a holimo joalo ka semiconductor le sefofane.
2. Litšebeletso tsa ho Etsa Lintho ka Bohona
Rea utloisisa hore bareki ba fapaneng ba na le litlhoko tse ikhethang tsa ho sila. Ho fihlela litlhoko tsa hau tse ikhethileng, re fana ka lits'ebeletso tse felletseng tsa ho iketsetsa:
Dikahare tsa alumina tse ikgethileng ho tsamaellana le tikoloho ya hao ya ho sila le dibopeho tsa thepa.
Boholo bo ikhethileng (ho tloha ho 1mm ho isa ho 50mm) le dibopeho (tse chitja, tse silindara, jj.).
Kalafo e khethehileng ea bokaholimo bakeng sa khanyetso e matla ea ho tsofala kapa ho fokotseha ha tšilafalo.
Litharollo tsa ho paka tse ikhethileng (ho paka ka bongata, ho paka ka mekotla, jj.) ho nolofatsa ho tsamaisoa le ho bolokoa.
Likaroloana:
Ho ba thata le ho hanyetsa ho apara ka matla:Bothata ba Mohs bo fihla ho 9 (haufi le daemane), ka sekhahla se tlase sa ho tsofala (<0.03%/1,000 lihora bakeng sa mehlala e hloekileng haholo). E hanela ho robeha le ho thothomela ha e siloa ka nako e telele, e leng se fellang ka bophelo bo bolelele ba ts'ebeletso.
Botebo bo Holimo le Bokgoni bo Holimo ba ho Sila:Ka bongata ba 3.6-3.9 g/cm³, e fana ka matla a matla le ho beola nakong ea ho sila, e ntlafatsa thepa kapele ho fihlela boemong ba micron, ka katleho e phahameng ka 20%-30% ho feta libolo tsa aluminium tsa maemo a mahareng le a tlase.
Litšila tse Tlase le Botsitso ba Lik'hemik'hale:Mehlala e hloekileng haholo e na le litšila tse ka tlase ho 1% (joalo ka Fe₂O₃), e thibelang tšilafalo ea thepa. E hanela boholo ba li-acid le li-alkali (ntle le li-acid tse matla le li-alkali tse kopaneng), mocheso o phahameng (kaholimo ho 800°C), 'me e loketse mefuta e fapaneng ea litsamaiso tsa ho sila.
Boholo bo Tenyetsehang le ho Sebeletsana:E fumaneha ka bophara ho tloha ho 0.3 ho isa ho 20 mm, bolo e ka sebelisoa ka boholo bo le bong kapa bo tsoakiloeng, e tsamaellana le li-ball mill, li-sand mill le lisebelisoa tse ling, e fihlela litlhoko tsohle ho tloha ho tse thata ho isa ho tse silang hantle.
