Munhandare dzendege, zvipatara, nzvimbo dzekutengesera, nzira dzepasi pevhu, zvivakwa zvepamusoro-soro uye dzimwe nzvimbo dzakakosha, kuitira kuti kuve nechokwadi chekuchengetedzwa kwevanhu kana pakaitika moto uye kushanda kwakajairwa kwehurongwa hwekukurumidzira, zvinodikanwa kushandisa tambo isingadzivirirwe nemoto uye tambo ine yakanakisa kudzivirira moto. Nekuda kwekuwedzera kutarisisa kuchengetedzeka kwemunhu, kudiwa kwemusika kwetambo dzinodzivirira moto kuri kuwedzera, uye nzvimbo dzekushandisa dziri kuramba dzichiwedzera, mhando yewaya isingadzivirirwe nemoto uye zvinodiwa netambo zviri kuwedzera zvakare.
Waya isingadziviriri moto uye tambo inoreva waya uye tambo ine kugona kushanda nguva dzose munzvimbo yakatarwa kana ichitsva pasi pemurazvo wakatsanangurwa nenguva, kureva kugona kuchengetedza kuperera kwemutsara. Waya isingadziviriri moto uye tambo kazhinji iri pakati pe conductor uye insulation layer pamwe nerefractory layer, iyo refractory layer inowanzove yakawanda-layer refractory mica tepi yakaputirwa zvakananga kutenderedza conductor. Inogona kupinzwa muchinhu chakaomarara, chakaomeswa insulator chakasungirirwa pamusoro pe conductor kana yaiswa pamoto, uye inogona kuve nechokwadi chekushanda kwakajairika kwemutsara kunyangwe iyo polima pamoto wakaiswa wakapiswa. Sarudzo yemoto isingadziviriri mica tepi saka inoita basa rakakosha mumhando yewaya dzinodzivirira moto uye tambo.
1 Kuumbwa kwematepi erefractory mica uye maitiro ega ega kuumbwa
Mune refractory mica tepi, iyo mica bepa ndiyo chaiyo magetsi ekuisa uye refractory zvinhu, asi iyo mica bepa pachayo rinenge risina simba uye rinofanirwa kusimbiswa nezvinhu zvinosimbisa kuti riwedzere, uye kuita kuti mica bepa uye inosimbisa zvinhu zvive munhu anofanira kushandisa chinonamira. Iyo mbishi yerefractory mica tepi saka inogadzirwa nebepa remica, inosimbisa zvinhu (jira regirazi kana firimu) uye resin adhesive.
1. 1 Mica bepa
Pepa reMica rakakamurwa kuita mhando nhatu zvichienderana nehunhu hwemica minerals inoshandiswa.
( 1) Mica bepa rakagadzirwa nechena mica;
( 2) Mica bepa rakagadzirwa negoridhe mica;
( 3) Mica bepa rakagadzirwa neyakagadzirwa mica seyakagadzirwa.
Aya marudzi matatu emapepa e mica ese ane hunhu hwawo
Mumhando nhatu dzepepa remica, tembiricha yekamuri yemagetsi ewhite mica bepa ndiyo yakanakisa, yekugadzira mica bepa ndeyechipiri, goridhe mica bepa haina kunaka. Zvimiro zvemagetsi pakupisa kwepamusoro, pepa rekugadzira mica ndiro rakanakisa, goridhe mica bepa ndiyo yechipiri kunaka, chena mica bepa haina kunaka. Synthetic mica haina crystalline mvura uye ine 1,370 ° C inonyunguduka, saka ine yakanyanya kupikisa kutonhora kwepamusoro; mica yegoridhe inotanga kusunungura mvura yekristalline pa800 ° C uye ine yechipiri yakanakisisa yekudzivisa kutonhora kwakanyanya; white mica inoburitsa crystalline mvura pa 600°C uye ine kushomeka kwekudzivirira kune tembiricha yakakwira. Goridhe mica uye synthetic mica inowanzo shandiswa kugadzira refractory mica matepi ane zvirinani zvinoramba.
1. 2 Kusimbisa zvinhu
Kusimbisa zvinhu zvinowanzova girazi jira uye firimu repurasitiki. Girazi jira ndeye inoenderera filament yegirazi fiber yakagadzirwa kubva kune alkali-isina girazi, iyo inofanirwa kurukwa. Iyi firimu inogona kushandisa marudzi akasiyana-siyana efirimu repurasitiki, kushandiswa kwefirimu yepurasitiki kunogona kuderedza mari uye kuvandudza kusagadzikana kweabrasion pamusoro pepamusoro, asi zvigadzirwa zvinogadzirwa panguva yekupisa hazvifaniri kuparadza kuvhara kwepepa remica, uye inofanira kuva nesimba rakakwana, ikozvino inowanzoshandiswa ifirimu yepolyester, firimu repolyethylene, nezvimwewo. kusimbiswa kunowanzo kukwirira kupfuura iyo mica tepi ine firimu reinforcement. Pamusoro pezvo, kunyangwe iyo IDF simba rematepi emica patembiricha yekamuri yakabatana nerudzi rwemica bepa, zvakare yakabatana zvakanyanya nesimbi yekusimbisa, uye kazhinji iyo IDF simba rematepi emica ine firimu reinforcement pakupisa kwekamuri yakakwira kupfuura iyo mica matepi pasina kusimbiswa kwefirimu.
1. 3 Resin adhesives
Iyo resin inonamatira inosanganisa iyo mica bepa uye yekusimbisa zvinhu kuita imwe. Iyo inonamira inofanirwa kusarudzwa kuti isangane nehupamhi hwechisungo chesimba remica bepa uye yekusimbisa zvinhu, iyo mica tepi ine kumwe kuchinjika uye haina char mushure mekupisa. Izvo zvakakosha kuti iyo mica tape haina kupisa mushure mekupisa, sezvo inokanganisa zvakananga kudzivirira kweiyo mica tape mushure mekupisa. Sekunamira, kana uchisunga mica bepa uye inosimbisa zvinhu, inopinda mukati me pores uye micropores yezvose zviri zviviri, inova mugero wemagetsi conductivity kana ichipisa uye char. Parizvino, iyo inowanzoshandiswa inonamira yerefractory mica tepi ndeye silicone resin adhesive, iyo inoburitsa chena silica poda mushure mekutsva uye ine yakanaka yemagetsi ekudzivirira zvinhu.
Mhedziso
( 1) Refractory mica matepi anowanzo gadzirwa uchishandisa goridhe mica uye synthetic mica, iyo ine zvirinani magetsi emagetsi pakupisa kwakanyanya.
(2) Kusimba kwesimba rematepi emica kune hukama nerudzi rwesimbi yekusimbisa, uye kusimba kwematepi emica tepi ane girazi rekusimbisa jira rinowanzo kukwirira kupfuura iwo emica matepi ane firimu reinforcement.
( 3) IDF simba rematepi e mica pane tembiricha yekamuri ine hukama nerudzi rwemica bepa, asiwo kune yekusimbisa zvinhu, uye kazhinji yakakwirira kune mica matepi ane firimu reinforcement pane avo vasina.
( 4) Zvinamira zvematepi asingadziviriri moto anowanzo kunamatira silicone.
