Kuchengetedzeka pamoto chinhu chakakosha muindasitiri yekuvaka, zvichikonzera kudiwa kwezvinhu zvinopisa zvine simba guru zvinogona kuramba kupisa kwakanyanya, kupararira kwemoto zvishoma nezvishoma, uye kuderedza kutamiswa kwekupisa. Ma-mica flakes asingatsvi, ane kugadzikana kwawo kwakanyanya pakupisa (achitsungirira kupisa kusvika 1200°C), kufambiswa kwemhepo kushoma, uye hunhu husingatsvi, zvave chinhu chakakosha mukuvaka zvinhu zvisingatsvi. Kusiyana nezvinhu zvinodzivirira moto zvakagadzirwa zvinogona kuburitsa magasi ane chepfu kana zvapiswa, ma-mica flakes ndeechisikigo, haana chepfu, uye anochengetedza chimiro chawo kunyangwe pakupisa kwakanyanya, zvichiita kuti zvive zvakanaka pamasuo emoto, maketeni emoto, uye mapaneru ekudzivirira madziro.

Mukugadzira magonhi emoto, ma mica flakes anosanganiswa nefiber yehuni kana mineral fiber kugadzira zvinhu zvepakati zvinodzivirira moto. Kana 20%-30% yema mica flakes asingatsvi moto (saizi yezvikamu 40-80 μm) akawedzerwa kune chinhu chepakati, chiyero chekudzivirira moto chegonhi remoto chinogona kuvandudzwa kubva pamaminitsi makumi matatu kusvika pamaminitsi makumi mapfumbamwe nemakumi maviri. Izvi zvinodaro nekuti ma mica flakes anoumba layer yakakora, inochengetedza kupisa kana yaiswa pamoto, ichidzivirira kutamiswa kwekupisa uye ichidzivirira gonhi kuti risatsvi kana kudonha. Mugadziri wezvinhu zvekuvaka muUK akaedza magonhi edu emoto akasimbiswa ne mica pasi pemamiriro emoto akajairwa (ISO 834): magonhi akachengetedza kugadzikana kwawo kwemaminetsi zana negumi, tembiricha yekumashure ichiramba iri pasi pe140°C (muganho wekupararira kwemoto), ichipfuura zvinodiwa zvemagonhi emoto eClass B.

Uyezve, magonhi emoto ane ma mica flakes akaratidza kushanda kwakanaka mumoto chaiwo. Mumoto wechivako chekugara chine nhurikidzwa dzakawanda muAustralia, magonhi emoto ane ma mica flakes akanonotsa kupararira kwemoto nehutsi, zvichipa nguva yakawanda kuti vagari vabude zvakachengeteka. Mushure memoto, zvakaonekwa kuti magonhi aya akachengetedza chikamu chakakura chehunhu hwawo, izvo zvakabatsira kuderedza kukuvara kwese kwechivako.

Pamusoro pezvo, ma mica flakes anovandudza simba remakemikari ema cores emoto, zvichideredza kukotama nekutsemuka panguva yekuisa nekushandisa. Chimiro chinobatana chinoumbwa nema mica flakes mukati mechinhu chepakati chinoshanda se network yekusimbisa, zvichipa rutsigiro rwakawedzerwa uye kugadzikana. Izvi hazvingowedzeredzi chete kudzivirira moto asiwo zvinowedzera hupenyu hwebasa rema mica doors.

Pamaketeni emoto—zvidziviriro zvinochinjika zvinoshandiswa kuvhara nzvimbo dzinopisa muzvivakwa zvemabhizinesi—macheni emumica anoputirwa pamachira anodzivirira kupisa kwakanyanya akadai segirazi fiber kana aramid fiber. Chidziviriro chemumica (chine 50%-60% mica flakes) chinoshanda sechidziviriro chekupisa, chichiratidza kusvika ku85% yekupisa kunopenya uye chichidzivirira jira kuti risanyunguduke. Imwe nzvimbo yekutengesa muSpain yakaisa maketeni emoto akagadzirwa nemacheni edu emumica anodzivirira kupisa: panguva yekuedzwa kwemoto kwakaedzwa, maketeni akamisa kupararira kwemoto kwemaminitsi makumi masere, zvichipa nguva yakakwana yekubvisa uye kudzima moto.

Uyezve, tsvakiridzo yakaratidza kuti kurongeka kwema mica flakes mu coating kunogona kukanganisa zvakanyanya mashandiro emaketeni emoto. Kana ma mica flakes akarongwa zvakanaka panguva yekurongeka, anogona kugadzira chidziviriro chinoshanda zvakanyanya pakupisa nemoto. Chikwata chedu cheR&D chakagadzira nzira yakasiyana yekurongeka iyo inovimbisa kurongeka kwakanaka kwema flake, zvichiwedzera hunhu hwemaketeni husingatsvi.

Kusiyana nemachira echinyakare ekudzivirira moto anoora mushure mekushandiswa kakawanda, machira ekudzivirira akavakirwa pamica anogara kwenguva refu, achichengetedza hunhu hwawo husingatsvi moto kwemakore anosvika gumi pasina kugadziriswa kwakawanda. Kugara kwenguva refu uku kunoita kuti machira ekudzivirira moto akafukidzwa nemica ave mhinduro inodhura zvishoma yezvivakwa zvemabhizinesi, zvichideredza kudiwa kwekutsiviwa kakawanda uye mari yekugadzirisa inoenderana nazvo.

Mumapaneru ekudzivirira madziro, maflakes e-mica anosanganiswa muzvinhu zvekudzivirira gypsum kana simende kuti awedzere kudziya kwekupisa uye kudzivirira moto. Kuwedzera 15%-25% yemaflakes e-mica kumapaneru ekudzivirira gypsum kunoderedza kufambiswa kwekupisa kubva pa0.17 W/(m·K) kusvika pa0.12 W/(m·K), zvichivandudza kushanda kwesimba ne25%-30%. Panguva imwe chete, kudzivirira moto kwemapaneru kunowedzera zvakanyanya—haabatidzi kana kuburitsa utsi hune chepfu kana hwakaiswa pamoto wakavhurika, zvichisangana nezvinodiwa zvakasimba zvekuchengetedza moto zveEuropean Union (EN 13501-1) neUnited States (ASTM E84).

Pamusoro pekuvandudza kudzivirira moto uye kupisa, ma mica flakes anobatsirawo mukushanda kwema acoustic panels ekuputira madziro. Maumbirwo ema mica anopwanyika anobatsira kunyudza nekudzikamisa mafungu eruzha, zvichideredza kutapurirana kweruzha pakati pemakamuri. Izvi zvinoita kuti ma mica-reinforced insulation panels ave sarudzo yakanaka yezvivakwa uko kudzivirira ruzha kuchikoshawo, zvakaita semahotera, zvikoro, nezvipatara.

Chirongwa chekuvaka dzimba muGermany chakashandisa mapaneru aya ekudzivirira kupisa akasimbiswa ne mica: zvivakwa zvakawana BREEAM Excellent rating yekushanda nesimba, uye bvunzo dzekuchengetedza moto dzakasimbisa kuti mapaneru aya akabatsira kudzikira kwe40% munjodzi yekupararira kwemoto zvichienzaniswa neaya akajairwa ekudzivirira kupisa. Kubudirira kwechirongwa ichi kwakaita kuti pave nekufarira kukuru mumapaneru ekudzivirira kupisa akasimbiswa ne mica muEurope yese, nevagadziri vakawanda nevakondirakiti vachivasarudza kuti vashande pamapurojekiti avo.

Maflakes edu emuca asingatsvi anowanikwa muzvikamu zviviri: maflakes emuscovite mica asingatsvi anopisa zvakanyanya (akagadzikana kusvika 750°C) uye maflakes ephlogopite mica anodziya zvakanyanya (akagadzikana kusvika 1200°C). Zviratidzo zvikuru zvehunyanzvi zvinosanganisira: hunyoro ≤0.3%, ash content ≤0.5%, thermal conductivity ≤0.08 W/(m·K), uye flame retardancy rating (UL94) V-0. Zvigadzirwa zvese zvinoedzwa zvakanyanya, kusanganisira thermal stability testing (mu muffle furnace), flame spread testing (uchishandisa cone calorimeter), uye chepfu gasi emission testing (zvichienderana ne ISO 19702), kuona kuti mitemo yekudzivirira moto inotevedzwa pasi rose.

Kuti tive nechokwadi chekuti ma mica flakes edu akanaka uye anowirirana, takaisa hurongwa hwakasimba hwekudzora mhando padanho rega rega rekugadzira. Kubva pakutsvaga zvinhu zvakabikwa kusvika pakurongedza kwekupedzisira, batch yega yega yema mica flakes inoongororwa nekunyatsoongororwa.

Tinopa rutsigiro rwakagadzirirwa vagadziri vezvinhu zvekuvaka. Kune vagadziri vemasuo emoto, tinokurudzira kushandisa phlogopite mica flakes pakushandiswa pakupisa kwakanyanya uye kubatsira mukuvandudza chiyero chekusanganisa kuti chienzane nekudzivirira moto nemutengo. Kune vanoputira machira emoto, tinopa ma micronized mica flakes (saizi yezvikamu 10-20 μm) anoumba coating yakatsetseka, yakafanana pasina kukanganisa kuchinjika kwejira. Chikwata chedu chehunyanzvi chinoitisawo kudzidziswa panzvimbo yacho nezve matekiniki ekupararira kwe mica flake, tichiona kuti zvinhu zvinopararira zvakaenzana kudzivirira nzvimbo dzisina kusimba mukudzivirira moto.

Pamusoro perutsigiro rwehunyanzvi, tinopawo masevhisi ekugadzira zvigadzirwa zvakagadzirwa nemaoko edu. Kana vatengi vaine zvinodiwa chaizvo zvehunhu hwemica flake, zvakaita sekupararira kwehukuru hwezvidimbu, kugadziriswa kwenzvimbo, kana ruvara, timu yedu yeR&D inogona kushanda pamwe chete navo kugadzira mhinduro yakagadzirwa nenzira yakakodzera. Kuchinjika uku kunotibvumira kusangana nezvinodiwa zvakasiyana-siyana zvevatengi vedu muindasitiri yezvinhu zvekuvaka.

Mukugadzira zvinhu, tinoshandisa mapakeji akavharwa nekupisa, asingatsvedzeri hunyoro (25 kg/bhegi) kudzivirira kuti ma flakes e mica asatore hunyoro, izvo zvinogona kuderedza kushanda kwawo kusingatsve. Tinoshanda pamwe chete nemakambani ekutakura zvinhu ane hunyanzvi mukugadzira zvinhu zvekuvaka, tichiendesa zvigadzirwa kuEurope, North America, neMiddle East mukati memazuva makumi maviri kusvika makumi matatu nemashanu.
