Ibisobanuro bigufi:

Udupira twa Mica, dufite imiterere yihariye ya lamellar, ubushobozi bwo kudahinduka mu binyabutabire, kandi duhuye neza n'udupira twa rubber, twerekanye ko ari utwuma dukora neza mu nganda za rubber. Bitandukanye n'utwuma dusanzwe nka karubone black cyangwa calcium carbonate, utwo dupira twa mica dutanga uburyo bwihariye bwo kongera imbaraga mu byuma, guhangana n'ikirere, no kudahinduka mu buryo bungana, bigatuma tuba amahitamo meza ku bicuruzwa bya rubber bikorera ahantu habi, harimo n'udupira tw'imodoka, imiyoboro ya rubber yo mu nganda, n'imikandara yo kohereza ibicuruzwa.

Mu rwego rw'udupfundikizo tw'imodoka, harimo udupfundikizo tw'inzugi, udupfundikizo tw'amadirishya, na gasket za moteri, udupfundikizo twa mica tugira uruhare runini mu kongera ubushobozi bwo kudacika no gukora neza. Utwo dupfundikizo duhura n'ibibazo byinshi bya mekanike, ihindagurika ry'ubushyuhe kuva kuri -40°C kugeza kuri 120°C, no kumara igihe kinini uhura n'imirasire ya UV, ibintu bishobora gutuma udupfundikizo dusanzwe twa rubber ducika, tugakomera, cyangwa tugatakaza ubushobozi bwo guhagarara uko igihe kigenda gihita.

Kongeraho 8%-15% by'udupira twa mica two mu rwego rwo hejuru, dufite ingano ya 30-80 μm n'igipimo cya ≥100, kuri ethylene-propylene-diene monomer (EPDM) rubber bitanga umusaruro utangaje. Ingufu zo gucika kw'urubber ziyongeraho 40%-60%, mu gihe igipimo cyo gukanda, gipimwe nyuma y'amasaha 70 kuri 100°C, kigabanuka cyane kuva kuri 35% kigera kuri 15%. Uruganda rukora ibikoresho by'imodoka rukomeye mu Budage rwakoze ibizamini byinshi rukoresheje udupira twa mica two mu masanduku y'inzugi ya EPDM. Ibisubizo byari bitangaje: udupira twa mica twakomeje kugira ubushobozi bwo gufunga no gufungura mu gihe cy'amasaha 500.000 yo gufungura no gufunga, ugereranyije n'udupira 300.000 gusa twa mica tudafite udupira twa mica. Ubu buzima bwongerewe ntibugabanya gusa ikiguzi cyo kubungabunga imodoka ahubwo bunanongera icyizere cy'ibicuruzwa by'imodoka.

Ku miyoboro ya rubber ikoreshwa mu kohereza imiti, amavuta n'amazi, mica flakes ni ingenzi mu kongera ubushobozi bwo kurwanya imiti no kurwanya umuvuduko. Iyi miyoboro ikunze guhura n'ibintu byangiza kandi igomba kwihanganira umuvuduko mwinshi w'imbere wa MPa 10. Mica flakes, hamwe n'imiterere yayo ya lamellar idapfa kwinjira, ikora uruzitiro rwiza muri matrix ya rubber, ikagabanya kwinjira kwa chemicals ku kigero cya 50%-70%.

Iyo yongewe mu miyoboro ya nitrile rubber (NBR) ku gipimo cya 10%-20%, mica flakes yongera cyane umuvuduko w'umuyoboro ku kigero cya 25%-35% kandi yongera igihe cyo kuyikoresha mu guhererekanya amavuta kuva ku mwaka 1 kugeza ku myaka 2-3. Uruganda rw'imiti rwo mu Buholandi rwagerageje imiyoboro yacu ya NBR yashyizwemo mica mu guhererekanya aside sulfure 20%. Ibisubizo byari byuzuye: nyuma y'amezi 12 yo gukoreshwa buri gihe, imiyoboro nta kimenyetso cyagaragaye cyo kubyimba cyangwa kuva amazi, mu gihe imiyoboro isanzwe ya NBR yananiwe nyuma y'amezi 4 gusa. Byongeye kandi, mica flakes yongera ubushobozi bwo kugumana imiyoboro ya rubber, ikagabanya gukama kw'imiyoboro mu gihe cyo gukurura vulcanization ku kigero cya 15%-25% kandi ikanatuma ikwirakwira neza n'ibihuza.

Uduce twose twa mica twujuje ibisabwa mu nganda mu bijyanye n'ibipimo by'ingenzi bya tekiniki. Ubushuhe ni ≤0.3%, ivu ni ≤0.5%, amavuta ni ≤25 mL/100g, kandi turwanya ubushyuhe neza, tugakomeza kumera neza ku bushyuhe bugera kuri 600°C. Byongeye kandi, ibicuruzwa byacu byubahiriza amabwiriza ya RoHS na REACH, aho ibyuma biremereye biri munsi y'amategeko mpuzamahanga (lead ni ≤0.0005%, arsenic ni ≤0.0003%).

Ku bijyanye n'ibijyanye n'ubwikorezi, dushyira imbere ubwiza n'ubuziranenge bw'ibicuruzwa byacu. Uduce twa mica dupfunyitse mu mifuka idapfa guhumeka (25 kg/umufuka), dufite agapira k'imbere ka polyethylene n'umufuka w'impapuro wo hanze kugira ngo hirindwe ko amazi yakwinjira mu gihe cyo gutwara abantu mu mazi. Twashyizeho ubufatanye bukomeye n'ibigo bikomeye by'ubwikorezi nka Maersk na COSCO, duharanira ko abakiriya bo mu Burayi, Amerika ya Ruguru, na Aziya y'Amajyepfo y'Uburasirazuba bagezwa ku gihe mu minsi 15-30.

Ibisobanuro birambuye ku gicuruzwa

Ibirango by'ibicuruzwa

Mica ni izina rusange ry'imyunyu ngugu ya mica. Ni aluminosilicate ya potasiyumu, aluminiyumu, manyeziyumu, icyuma, lithiyumu n'ibindi byuma, byose bikaba bifite imiterere imwe kandi bigizwe n'ibice bibiri. Kristale ni pseudohexagonal lamellae cyangwa plate like, rimwe na rimwe columnar. Lamellar breakavage yuzuye cyane, ifite ikirahure gisa n'urupapuro rworoshye. Igipimo cyo kugarura ubushyuhe cya mica kiriyongera uko icyuma cyiyongera, kuva ku gice gito kugeza ku gice kiringaniye. Ubwoko budafite icyuma ntibugira ibara mu gice. Uko icyuma kiri hejuru, niko ibara ryijimye, kandi niko gikora polychromatic kandi gifata.

Ingano y'udusate twa Mica: mesh 6-10, mesh 10-20,
Ifu ya Mica: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh na 5000mesh.

Porogaramu
Mu nganda, biotite ikoresha cyane cyane uburyo bwayo bwo gukingira no kurwanya ubushyuhe, ndetse no kurwanya aside, kurwanya alkali, kurwanya gukanda no kurwanya gushishwa, nk'ibikoresho byo gukingira ibikoresho by'amashanyarazi n'ibikoresho by'amashanyarazi; icya kabiri, ikoreshwa mu gukora amadirishya n'ibice bya mekanike by'amaboilers y'umwuka n'amatanura ashongeshwa. Uduce twa Mica n'ifu ya mica bishobora gutunganywa mu mpapuro za mica, kandi bishobora no gusimbura impapuro za mica kugira ngo bikore ibikoresho bitandukanye bihendutse kandi bifite ubunini bungana.

Muscovite ni yo ikoreshwa cyane mu nganda, ikurikirwa na phlogopite. Ikoreshwa cyane mu nganda z'ibikoresho by'ubwubatsi, inganda zirwanya inkongi, ibikoresho bizimya umuriro, inkoni yo gusudira, pulasitiki, amashanyarazi akingira, gukora impapuro, impapuro za asphalt, kabuti, ibara ry'urutare n'izindi nganda zikora imiti.

Ifu ya mica nziza cyane ikoreshwa nk'inyunganiramirire ya pulasitiki, irangi, irangi, rabha n'ibindi, bishobora kongera imbaraga zayo mu ikoranabuhanga, kongera gukomera, gufatana, kurwanya gusaza no kurwanya ingese.
