Kufanana ndi kusiyana kwa zipangizo zatsopano za refractory vitrified refractory silicon tepi ndi tepi ya refractory mica (1)

Zingwe zosagwira mototchulani zingwe zomwe zimatha kugwira ntchito motetezeka kwa nthawi inayake pansi pamoto woyaka.Muyezo wa dziko langa GB12666.6 (monga IEC331) umagawaniza kuyesa kukana moto m'magulu awiri, A ndi B. Kutentha kwamoto kwa kalasi A ndi 950 ~ 1000 ℃, ndipo nthawi yoperekera moto ndi 90min.Kutentha kwa lawi la kalasi B ndi 750 ~ 800 ℃, ndipo nthawi yoperekera moto ndi mphindi 90.min, pa nthawi yonse yoyesa, chitsanzocho chiyenera kupirira mtengo wamagetsi wotchulidwa ndi chinthucho.

Zingwe zosagwira moto zimagwiritsidwa ntchito kwambiri m'nyumba zokwera kwambiri, njanji zapansi panthaka, misewu yapansi panthaka, malo opangira magetsi akuluakulu, mabizinesi ofunikira amakampani ndi migodi ndi malo ena okhudzana ndi chitetezo chamoto ndi kuzimitsa moto ndi kupulumutsa moyo, monga mizere yamagetsi ndi mizere yowongolera. za zinthu zadzidzidzi monga zida zozimitsira moto ndi magetsi owongolera mwadzidzidzi.

Pakali pano, mawaya ambiri osagwira moto ndi zingwe kunyumba ndi kunja amagwiritsa ntchito magnesium oxide mineral insulated zingwe ndi mica tepi-bala-chilonda zosagwira moto;mwa iwo, mawonekedwe a magnesium oxide mineral insulated zingwe akuwonetsedwa pachithunzichi.

Magnesium oxide mineral insulated chingwe ndi mtundu wa chingwe chosagwira moto chomwe chimagwira bwino ntchito.Amapangidwa ndi copper core, copper sheath, ndi magnesium oxide insulating material.Amatchedwa MI (minerl insulated cables) mwachidule.Chingwe chosagwira moto cha chingwecho chimapangidwa ndi zinthu zosagwirizana ndi moto, pomwe chingwe chosagwirizana ndi zingwe zosagwirizana ndi moto chimapangidwa ndi zinthu zopanda organic ndi zinthu zambiri zachilengedwe.Chifukwa chake, magwiridwe antchito osagwira moto a zingwe za MI ndiabwino kuposa zingwe wamba zosagwira moto ndipo sizimayambitsa dzimbiri chifukwa cha kuyaka ndi kuwola.gasi.Zingwe za MI zili ndi zinthu zabwino zosagwira moto ndipo zimatha kugwira ntchito pa kutentha kwa 250 ° C kwa nthawi yayitali.Pa nthawi yomweyo, iwonso kuphulika-umboni, mphamvu dzimbiri kukana, lalikulu kunyamula mphamvu, kukana radiation, mkulu makina mphamvu, kakang'ono, kulemera kuwala, moyo wautali, ndi utsi zapaderazi.Komabe, mtengo wake ndi wokwera mtengo, ndondomekoyi ndi yovuta, ndipo kumanga ndi kovuta.M'madera othirira mafuta, nyumba zofunikira zamatabwa zamatabwa, malo otentha kwambiri ndi nthawi zina zomwe zimakhala ndi zofunikira zotsutsana ndi moto komanso chuma chovomerezeka, chingwe chamtunduwu chokhala ndi moto wabwino chingagwiritsidwe ntchito, koma chingagwiritsidwe ntchito pa Low voltage fire resistant. zingwe.

Chingwe chosagwira moto wokutidwa ndimica tepiimavulazidwa mobwerezabwereza ndi zigawo zingapo za tepi ya mica kunja kwa kondakitala kuteteza lawi kuti lisapse, potero kumatalikitsa nthawi yogwira ntchito yotetezeka ndikusunga mzere wosatsekeka kwa nthawi inayake.

magnesium oxide
White amorphous ufa.Zopanda fungo, zosakoma komanso zopanda poizoni.Ili ndi kukana kwamphamvu kwambiri komanso kotsika kutentha (kutentha kwa 2500 ℃, kutentha kochepa -270 ℃), kukana dzimbiri, kutchinjiriza, madulidwe abwino amafuta ndi mawonekedwe owoneka bwino, kristalo wopanda mtundu komanso wowonekera, malo osungunuka 2852 ℃.Magnesium oxide imakhala ndi mphamvu zolimbana ndi moto komanso zotsekera, ndipo imakhala ndi malo osungunuka kwambiri.Amagwiritsidwa ntchito popanga zingwe za magnesium oxide mineral insulated fire zosagwira zingwe.
Mica tepi

Mica ndi mchere wonyezimira wonyezimira, womwe umadziwika ndi kutsekereza, kukana kutentha kwambiri, kuwala, kukhazikika kwakuthupi ndi mankhwala, kutentha kwabwino, kukhazikika, kulimba komanso kusayaka, ndipo amachotsedwa kukhala zotanuka zamasamba owonekera.

Mica tepiamapangidwa ndi flake mica ufa mu mica pepala, amene amamatira ku galasi CHIKWANGWANI nsalu ndi zomatira.

Nsalu yagalasi yomwe imayikidwa kumbali imodzi ya pepala la mica imatchedwa "tepi ya mbali imodzi", ndipo yomwe imayikidwa kumbali zonse ziwiri imatchedwa "tepi yamitundu iwiri".Popanga, zigawo zingapo zimamatira pamodzi, zowumitsidwa mu uvuni, zomangika, ndi kuzidula kukhala matepi amitundu yosiyanasiyana.
Mica tepi, yomwe imadziwikanso kuti mica yosagwira moto, imapangidwa ndi (makina a mica tepi).Ndi mtundu wa zida zoteteza moto zosagwira.Malingana ndi ntchito yake, ikhoza kugawidwa mu: mica tepi ya injini ndi mica tepi ya zingwe.Malinga ndi kapangidwe kake, amagawidwa kukhala: lamba wambali ziwiri, lamba wamtundu umodzi, lamba wachitatu-mumodzi, lamba wamafilimu awiri, lamba wafilimu imodzi, etc. Malingana ndi mica, akhoza kugawidwa kukhala: kupanga. mica tepi, phlogopite mica tepi, ndi muscovite tepi.

(1) Kutentha kwanthawi zonse: tepi yopangira mica ndiyo yabwino kwambiri, yotsatiridwa ndi tepi ya muscovite, ndipo tepi ya phlogopite ndiyosauka.

(2) Kuchita kwa insulation pa kutentha kwakukulu: tepi yopangira mica ndiyo yabwino kwambiri, yotsatiridwa ndi tepi ya phlogopite mica, ndi tepi ya muscovite ndiyosauka.

(3) Kutentha kwapamwamba kwambiri: Tepi ya mica yopangidwa, ilibe madzi akristalo, malo osungunuka 1375 ° C, kukana kutentha kwambiri, phlogopite imatulutsa madzi akristalo pamwamba pa 800 ° C, kutsatiridwa ndi kukana kutentha kwakukulu, muscovite imatulutsa makhiristo pa 600. ° C Madzi, kukana kutentha kwambiri.

Ceramic refractory silikoni mphira
Chifukwa cha kuchepa kwa ndondomekoyi, chingwe chosagwira moto chomwe chimakulungidwa ndi tepi ya mica nthawi zambiri chimayambitsa zolakwika m'malo olumikizirana mafupa.Pambuyo pochotsa, tepi ya mica imakhala yolimba komanso yosavuta kugwa, zomwe zimapangitsa kuti zisawonongeke ndi moto.Kusungunula, kumakhala kosavuta kugwa pamene kugwedezeka, choncho n'zovuta kuonetsetsa kuti kuyankhulana kotetezeka komanso kosalala kwa nthawi yayitali ndi mphamvu pakakhala moto.

Magnesia mineral insulated insulated zingwe zosagwira moto zimafunika kuitanitsa zida zapadera, mtengo wake ndi wokwera mtengo kwambiri, ndipo ndalama zazikulu ndi zazikulu;kuonjezera apo, chikwama chakunja cha chingwechi ndi mkuwa, choncho mtengo wa mankhwalawa umapangitsanso kuti mankhwalawa akhale okwera mtengo;kuphatikiza Chingwe chamtunduwu chimakhala ndi zofunikira zapadera popanga, kukonza, kuyendetsa, kuyika mzere, kukhazikitsa ndi kugwiritsa ntchito, ndipo ndizovuta kufalitsa ndikuzigwiritsa ntchito pamlingo waukulu, makamaka m'nyumba za anthu.
