<\/p>","protected":false},"excerpt":{"rendered":"Ahoj! Po\u010duli ste niekedy o Alumina 92? Nie? Tak sa prip\u00fatajte, preto\u017ee sa v\u00e1m chyst\u00e1m vyf\u00faknu\u0165 hlavu nejakou keramickou vedou, ktor\u00e1 je vlastne celkom fajn.<\/p>\n
Tak\u017ee, Alumina 92. Je to tvrd\u00e1 keramika s obsahom oxidu hlinit\u00e9ho 92%. T\u00fdch \u010fal\u0161\u00edch 8%? To s\u00fa len nejak\u00e9 n\u00e1hodn\u00e9 oxidy, ktor\u00e9 sa tam hodili pre zauj\u00edmavos\u0165. Ale e\u0161te nez\u00edvajte - tento materi\u00e1l je naozaj p\u00f4sobiv\u00fd.<\/p>\n
Po prv\u00e9, Alumina 92 je hardcore. Hovor\u00edme tu o n\u00e1ro\u010dnosti na \u00farovni pre\u017eitia apokalypsy. T\u00e1to keramika sa smeje tv\u00e1rou v tv\u00e1r extr\u00e9mnym hor\u00fa\u010dav\u00e1m, odol\u00e1va kor\u00f3zii ako ni\u010d a zost\u00e1va pevn\u00e1. Je to v podstate Termin\u00e1tor sveta materi\u00e1lov.<\/p>\n
Mo\u017eno si teraz hovor\u00edte: \"Dobre, je to \u0165a\u017ek\u00e9. Ve\u013ek\u00e9 hal\u00f3.\" Ale po\u010dkajte chv\u00ed\u013eu. V\u010faka tejto h\u00fa\u017eevnatosti je Alumina 92 skuto\u010dn\u00fdm expertom na v\u0161etko. Potrebujete nie\u010do, \u010do sa neroztop\u00ed vo va\u0161ej \u0161ialene hor\u00facej priemyselnej peci? Alumina 92 sa o v\u00e1s postar\u00e1. M\u00e1te nepr\u00edjemn\u00fd chemick\u00fd roztok, ktor\u00fd v\u0161etko pre\u017eerie? T\u00e1to keramika hovor\u00ed \"prive\u010fte ju\". Dokonca ju strkaj\u00fa \u013eu\u010fom do tela na implant\u00e1ty bedrov\u00fdch k\u013abov. Hovor\u00edme o univerz\u00e1lnosti!<\/p>\n
Po\u010fme sa na chv\u00ed\u013eu pozrie\u0165 trochu do tajov \u0161prtania. Na Mohsovej stupnici tvrdosti (\u00e1no, to je skuto\u010dn\u00e1 vec) m\u00e1 hlin\u00edk 92 sk\u00f3re 9 z 10. Diamant m\u00e1 10 bodov. Tak\u017ee tento materi\u00e1l je tvrd\u0161\u00ed ako klince - je tvrd\u0161\u00ed ako takmer v\u0161etko okrem doslovn\u00fdch diamantov. V\u00e1\u0161 kuchynsk\u00fd n\u00f4\u017e by nemal \u0161ancu.<\/p>\n
Hlin\u00edk 92 v\u0161ak nie je len tvrd\u00fd - v\u00fdborne zn\u00e1\u0161a aj opotrebovanie. V\u010faka tomu je ide\u00e1lny pre veci, ktor\u00e9 musia \u010deli\u0165 ve\u013ek\u00e9mu treniu. Spome\u0148te si na \u010dasti strojov, ktor\u00e9 sa o seba neust\u00e1le tr\u00fa. A e\u0161te toto - pou\u017e\u00edva sa v nepriestreln\u00fdch vest\u00e1ch. \u00c1no, t\u00e1to keramika dok\u00e1\u017ee zastavi\u0165 gu\u013eky. \u010co poviete na trik na p\u00e1rty?<\/p>\n
Teraz sa po\u010fme porozpr\u00e1va\u0165 o teple. Hlin\u00edk 92 zvl\u00e1dne teploty, ktor\u00e9 by v\u00e4\u010d\u0161inu vec\u00ed zmenili na kalu\u017ee. Hovor\u00edme o teplot\u00e1ch nad 3000 \u00b0C. To je teplej\u0161ie ako povrch Venu\u0161e, v\u00e1\u017een\u00ed. V\u010faka tomu sa v\u00fdborne hod\u00ed na veci, ako je n\u00e1bytok do pece - viete, veci, ktor\u00e9 dr\u017eia in\u00e9 veci, k\u00fdm sa vypa\u013euj\u00fa v super hor\u00facich peciach.<\/p>\n
Ale po\u010dkajte, je toho viac! (Prisah\u00e1m, \u017ee sa v\u00e1m nesna\u017e\u00edm ni\u010d preda\u0165.) Hlin\u00edk 92 je tie\u017e skvel\u00fd na udr\u017eiavanie elektriny pod kontrolou. Je ako pr\u00edsny rodi\u010d vo svete materi\u00e1lov, ktor\u00fd sa star\u00e1 o to, aby sa elektr\u00f3ny spr\u00e1vali slu\u0161ne.<\/p>\n
Pre\u010do teda tento z\u00e1zra\u010dn\u00fd materi\u00e1l nepou\u017e\u00edvame na v\u0161etko? M\u00e1 nieko\u013eko nev\u00fdhod. Po prv\u00e9, jeho v\u00fdroba nie je lacn\u00e1. Proces zah\u0155\u0148a varenie pr\u00e1\u0161kov\u00e9ho oxidu hlinit\u00e9ho pri teplot\u00e1ch, pri ktor\u00fdch by sa \u010dervenala aj sopka. To nie je pr\u00e1ve projekt na z\u00e1hradu.<\/p>\n
Aj oxid hlinit\u00fd 92 m\u00f4\u017ee by\u0165 trochu kr\u00e1\u013eovnou dr\u00e1my, ke\u010f pr\u00edde k n\u00e1hlym n\u00e1razom. Je ve\u013emi tvrd\u00fd, ale sta\u010d\u00ed do neho udrie\u0165 a m\u00f4\u017ee praskn\u00fa\u0165. To je d\u00f4vod, pre\u010do nem\u00e1me taniere Alumina 92. Viete si predstavi\u0165, \u017ee by v\u00e1m jeden z nich spadol na prst na nohe? Au.<\/p>\n
V\u00fdroba tejto z\u00e1zra\u010dnej keramiky je pomerne n\u00e1ro\u010dn\u00fd proces. Za\u010d\u00ednaj\u00fa s ve\u013emi \u010dist\u00fdm pr\u00e1\u0161kom oxidu hlinit\u00e9ho, primie\u0161aj\u00fa do neho \u010fal\u0161ie l\u00e1tky a potom ho tvaruj\u00fa, ako chc\u00fa. Potom prich\u00e1dza z\u00e1bavn\u00e1 \u010das\u0165 - v podstate ju varia v r\u00fare dostato\u010dne hor\u00facej na to, aby sa roztopila hornina. Je to ako pe\u010denie su\u0161ienok, keby va\u0161e su\u0161ienky vydr\u017eali n\u00e1vrat z vesm\u00edru.<\/p>\n
Po tom v\u0161etkom musia hlin\u00edk 92 \u010dasto br\u00fasi\u0165 alebo reza\u0165 do kone\u010dn\u00e9ho tvaru. Je to pribli\u017ene tak\u00e9 jednoduch\u00e9, ako to znie - potrebuj\u00fa n\u00e1stroje s diamantov\u00fdmi hrotmi, aby urobili len ryhu. Je to ako pok\u00fa\u0161a\u0165 sa vyreza\u0165 sochu z naozaj tvrdej keramiky.<\/p>\n
Napriek tomu, \u017ee pr\u00e1ca s hlin\u00edkom 92 je nepr\u00edjemn\u00e1, \u013eudia st\u00e1le nach\u00e1dzaj\u00fa nov\u00e9 sp\u00f4soby jeho vyu\u017eitia. Nach\u00e1dza sa vo v\u0161etkom, od fantastick\u00fdch palivov\u00fdch \u010dl\u00e1nkov a\u017e po umel\u00e9 zuby. Kto by povedal, \u017ee ten ist\u00fd materi\u00e1l, ktor\u00fd sa pou\u017e\u00edva v priemyseln\u00fdch peciach, m\u00f4\u017ee skon\u010di\u0165 vo va\u0161ich \u00fastach?<\/p>\n
Vedci sa neust\u00e1le sna\u017eia, aby bol oxid hlinit\u00fd 92 e\u0161te chladnej\u0161\u00ed. Niektor\u00ed prid\u00e1vaj\u00fa drobn\u00e9 \u010dastice, aby ho e\u0161te viac posilnili. In\u00ed sa ho sna\u017eia vytla\u010di\u0165 3D tla\u010dou, preto\u017ee be\u017en\u00e1 3D tla\u010d zrejme nebola dos\u0165 n\u00e1ro\u010dn\u00e1.<\/p>\n
Tak to m\u00e1te - Alumina 92 v celej svojej kr\u00e1se. Je odoln\u00fd, univerz\u00e1lny a pravdepodobne sa nach\u00e1dza vo viacer\u00fdch veciach okolo v\u00e1s, ne\u017e si mysl\u00edte. Nabud\u00face, ke\u010f budete na ve\u010dierku a niekto spomenie Alumina 92 (preto\u017ee to sa st\u00e1va st\u00e1le, v\u0161ak?), m\u00f4\u017eete ich oslni\u0165 svojimi keramick\u00fdmi znalos\u0165ami. Len sa nepok\u00fa\u0161ajte demon\u0161trova\u0165 t\u00fdm, \u017ee by ste zhodili nejak\u00fd tanier Alumina 92 - mohol by sa od\u0161tiepi\u0165 a v\u00e1\u0161 hostite\u013e by to pravdepodobne neocenil.<\/p>\n
Nakoniec je Alumina 92 ako ten nen\u00e1padn\u00fd superhrdina, ktor\u00fd sa skr\u00fdva pred o\u010dami. Mo\u017eno nie je tak\u00fd ok\u00e1zal\u00fd ako niektor\u00e9 in\u00e9 materi\u00e1ly, ale v tichosti zachra\u0148uje situ\u00e1ciu nespo\u010detn\u00fdmi sp\u00f4sobmi. Tak\u017ee na Alumina 92 - nech je aj na\u010falej neopievan\u00fdm hrdinom sveta materi\u00e1lov, jedna aplik\u00e1cia odoln\u00e1 vo\u010di kor\u00f3zii pri vysokej teplote za druhou!<\/p>\n
