Silicio karbidas (SiC) yra nat\u016bralus mineralas, vadinamas karborundu. Be to, egzistuoja ir dirbtin\u0117 jo forma, vadinama sintetiniu moisanitu.<\/p>\n
Akmenys yra klasikiniai ir universal\u016bs galandinimo \u012frankiai, ta\u010diau prie\u0161 naudojim\u0105 juos reikia reguliariai mirkyti ir lyginti, kad pavir\u0161ius b\u016bt\u0173 lygus. Apval\u016bs akmenys paprastai tur\u0117t\u0173 b\u016bti naudojami kaip galandinimo sekos dalis, pradedant nuo indi\u0161ko arba kristalinio akmens.<\/p>\n
Galandimo akmenys nuo seno naudojami kaip veiksminga priemon\u0117 a\u0161men\u0173 briaunoms gal\u0105sti. \u0160\u012f proces\u0105, vadinam\u0105 honing, galima atlikti naudojant nat\u016brali\u0105 arba dirbtin\u0119 abrazyvin\u0119 med\u017eiag\u0105, kuri skirstoma \u012f skirtingus gr\u016bd\u0117tumo lygius pagal tai, kokio \u0161iurk\u0161tumo yra kiekvienas akmuo; \u0161iurk\u0161tesni akmenys paprastai skirti sunkesn\u0117ms u\u017eduotims atlikti, pavyzd\u017eiui, pa\u017eeistiems ar \u012fskilusiems kra\u0161tams pertvarkyti, o smulkesniais akmenimis galima poliruoti ir tobulinti jau u\u017ea\u0161trint\u0105 briaun\u0105. Kombinuotuose rinkiniuose da\u017enai b\u016bna stambesn\u0117s ir smulkesn\u0117s pus\u0117s, tod\u0117l naudotojai gali atlikti ir sunk\u0173 darb\u0105, ir poliruoti bei tobulinti jau u\u017ea\u0161trint\u0105 briaun\u0105 - puik\u016bs kombinuotieji rinkiniai b\u016bna su stambesn\u0117mis pus\u0117mis, skirtomis sunkiam darbui ir smulkiam u\u017ebaigimui!<\/p>\n
Vandens akmenys - tai naujovi\u0161ki galandinimo akmenys, pagaminti i\u0161 nat\u016brali\u0173 ir sintetini\u0173 med\u017eiag\u0173, kuriems naudojamas vanduo kaip lubrikantas. Prie\u0161 naudojant \u0161iuos akmenis reikia kelias minutes pamirkyti, kad visas abrazyvinis gr\u016bd\u0117tumas b\u016bt\u0173 padengtas skys\u010diu ir peiliai ar \u012frankiai, pavyzd\u017eiui, gal\u0105stuvai, b\u016bt\u0173 itin glotn\u016bs. Galima rinktis i\u0161 daugyb\u0117s form\u0173, i\u0161 kuri\u0173 populiariausia yra sta\u010diakamp\u0117 - trikampiai ir apval\u016bs akmenys gali tur\u0117ti lenktus pavir\u0161ius, tinkamus \u012frankiams, kuri\u0173 pavir\u0161iai apval\u016bs, pavyzd\u017eiui, gal\u0105stuvams, gal\u0105sti.<\/p>\n
Kai kuriuose plienuose, pavyzd\u017eiui, D2 ir 440C, yra kiet\u0173j\u0173 karbid\u0173, kurie l\u0117tina \u0161lifavim\u0105 ant aliuminio oksido arba nat\u016bralaus akmens pavir\u0161iaus. Siekiant grei\u010diau ir efektyviau pjauti tokius metalus, silicio karbido akmenys si\u016blo 25% kietesnes pjovimo briaunas, kurios leid\u017eia grei\u010diau pjauti nei j\u0173 aliuminio oksido analogai.<\/p>\n
Apdirbant tokius metalus kaip mink\u0161tasis aliuminis, gali b\u016bti naudingiau apdirbti silicio karbido, o ne aliuminio oksido akmeniu, nes \u0161lifuojant kietieji abrazyvai ma\u017eiau \u012fkaista ir galima i\u0161gauti lygesn\u0119 apdail\u0105, ma\u017eiau pa\u017eeid\u017eiant med\u017eiag\u0105.<\/p>\n
Silicio karbid\u0105 galima naudoti dekoratyviniam graviravimui ant stiklo ir brangakmeni\u0173 pavir\u0161i\u0173, taip pat aliuminio liejini\u0173 \u0161lifavimui. Juo i\u0161gaunama smulkesn\u0117 apdaila nei Arkanzaso akmenimis, ta\u010diau jis palieka tamsesnius, prislopintus atspalvius nei deimantiniai frezos - puikiai tinka naudoti mink\u0161t\u0173j\u0173 metal\u0173 detal\u0117ms, kurias gali reik\u0117ti baigti apdirbti naudojant alternatyvius sm\u0117liavimo b\u016bdus, pvz., \u0161\u012f alternatyv\u0173 mink\u0161t\u0173j\u0173 metal\u0173 pavir\u0161i\u0173 poliravimo metod\u0105.<\/p>\n
Silicio karbido akmenys taip pat gali b\u016bti idealus pasirinkimas med\u017eio rai\u017einiams ir stiklui apdirbti, nes juos lengviau kontroliuoti nei \u0161lifavimo akmenis, o j\u0173 apdaila yra tolygesn\u0117. Ta\u010diau reik\u0117t\u0173 pa\u017eym\u0117ti, kad silicio karbido akmenys d\u0117visi grei\u010diau nei tradiciniai stendiniai akmenys, tod\u0117l, norint i\u0161laikyti tolyg\u0173 pavir\u0161i\u0173, juos reikia reguliariai lyginti.<\/p>\n
Silicio karbido akmenys gali b\u016bti naudojami peiliams gal\u0105sti, ta\u010diau d\u0117l kietesnio sukibimo paprastai naudojami tik apdailos akmenims. Kadangi \u0161ie akmenys reikalauja agresyvaus \u0161lifavimo, juos reikia tepti vandeniu arba aliejumi, kad neperkaist\u0173 ir nesusid\u0117v\u0117t\u0173; naudojimo metu juos taip pat reikia da\u017enai ap\u0161lakstyti vandeniu, nes palikti vieni jie greitai i\u0161d\u017ei\u016bsta.<\/p>\n
Silicio karbido \u0161lifavimo akmenys da\u017enai naudojami marmuro ir granito pavir\u0161iams \u0161lifuoti, ta\u010diau jie taip pat gerai tinka metalui \u0161lifuoti, gipskartonio plok\u0161\u010di\u0173 apdailai ir kam\u0161tienos apdailai. J\u0173 siauros formos dalel\u0117s greitai \u012fsir\u0117\u017eia \u012f med\u017eiag\u0105, naudojant minimal\u0173 spaudim\u0105, ir i\u0161gaunamas itin lygus pavir\u0161ius, kurio prie\u0161 blizgant nereikia tiek daug \u0161lifuoti! Be to, silicio karbido akmenys gali pad\u0117ti nu\u0161lifuoti aliuminio liejinius.<\/p>\n
Tokios kokyb\u0117s granul\u0117s idealiai tinka plienui, mink\u0161tiesiems metalams (variui, bronzai, auksui ir sidabrui), taip pat mink\u0161tosioms med\u017eiagoms, pavyzd\u017eiui, marmurui ir stiklui, \u0161lifuoti. Taip pat galima naudoti rankinius arba elektra ir oru varomus \u0161lifuoklius.<\/p>\n
\u0160ie \u017eali silicio karbido akmen\u0117liai pad\u0117s jums i\u0161gauti smulkesn\u012f ir detalesn\u012f dekoratyvin\u012f graviravim\u0105 ant stiklo, akmens ir brangakmeni\u0173. Be to, juos rekomenduojama naudoti graveriams, norintiems ant ner\u016bdijan\u010diojo plieno ir kit\u0173 juod\u0173j\u0173 metal\u0173 i\u0161gauti \u0161velnesn\u0119 pavir\u0161iaus apdail\u0105 nei naudojant deimantinius frezus.<\/p>\n
Silicio karbidas, da\u017eniau vadinamas karborundu, nat\u016braliai randamas kaip retas mineralas moisanitas, ta\u010diau masi\u0161kai prad\u0117tas gaminti 1893 m. ir naudojamas kaip abrazyvin\u0117 ir pramonin\u0117 sunkiai d\u0117vima med\u017eiaga. Gaminamas reaguojant ir pirolizuojant i\u0161garintus polisiloksanus \u012f silicio karbid\u0105, naudojant reakcijos\/piroliz\u0117s procesus, SiAlON sujungimo arba cheminio gar\u0173 nusodinimo b\u016bdu galima gaminti \u012fvairi\u0173 form\u0173 silicio karbid\u0105.<\/p>\n
Silicio karbido akmen\u012f (ir net nat\u016bral\u0173) reikia nuolat \u0161lifuoti, kad i\u0161likt\u0173 plok\u0161\u010dias. Vienas i\u0161 b\u016bd\u0173 - naudoti birius sic miltelius su vandeniu arba da\u017e\u0173 skiedikliu; trinti jo pavir\u0161i\u0173 pirmyn ir atgal, kartais sukamaisiais judesiais; taip nudau\u017eomos bet kokios auk\u0161tos akmens vietos ir atstatomas jo plok\u0161tumas.<\/p>\n
Karborundas (SiC) yra itin kietas ir patvarus puslaidininkinis junginys, sudarytas i\u0161 silicio ir anglies. Nors SiC nat\u016braliai randamas ribotais kiekiais kaip moisanito mineral\u0173 telkiniai, nuo 1893 m. j\u012f gaminant milteli\u0173 ir kristal\u0173 pavidalu buvo galima pla\u010diai naudoti kaip abrazyvin\u0119 ir keramin\u0119 med\u017eiag\u0105 srityse, kuriose reikia didelio patvarumo, pavyzd\u017eiui, automobili\u0173 stabd\u017eiuose ir sankabose arba neper\u0161aunamose liemen\u0117se; be to, jis populiariai naudojamas kaip brangakmeni\u0173 med\u017eiaga, pavyzd\u017eiui, sintetinis moisanitas.<\/p>\n
Silicio karbidas yra nuo bespalvio iki rudo atspalvio, o d\u0117l gele\u017eies priemai\u0161\u0173, esan\u010di\u0173 gele\u017eies sud\u0117tyje, pasi\u017eymi vaivoryk\u0161tiniu blizgesiu. Jis yra puikus elektros laidininkas ir gali net pasi\u017eym\u0117ti metaliniu laidumu, jei yra dopingas boru, fosforu ar aliuminiu.<\/p>","protected":false},"excerpt":{"rendered":"
