Kufotokozera Kwachidule:

Njerwa Yotenthetsera Silika Yopepuka ndi mtundu umodzi wa njerwa zotenthetsera zopepuka zokhala ndi silika yoposa 91% komanso zosakwana 1.2g/cm3, njerwa zotenthetsera silica zimatha kugwira ntchito kutentha kwakukulu pakati pa 1500 ~ 1550℃ kwa nthawi yayitali ndipo njerwa zotenthetsera silikoni zimagwiritsidwa ntchito kwambiri potenthetsera ng'anjo yamafakitale monga ng'anjo yagalasi ndi ma boiler ena a ng'anjo okhala ndi kulemera kopepuka, mphamvu yayikulu komanso kutentha kochepa.

Kufotokozera kwa Njerwa Zotetezera Silika

Njerwa Yotenthetsera Silika Yopepuka imagwiritsa ntchito miyala ya silika yogawanika bwino ngati zopangira. Kukula kwa tinthu tofunikira sikupitirira 1mm, momwemo kukula kwa tinthu toposa 90% ndi kochepera 0.5mm. Njerwa yotenthetsera silica imapangidwa powonjezera chinthu choyaka moto mu njira yolemetsa kapena kugwiritsa ntchito mpweya kuti ipange kapangidwe kake koboola kudzera mu kuwombera, njerwa zotenthetsera silica zimathanso kupangidwa kuti zikhale zosayaka.

Katundu wa Njerwa Yotetezera Silika Yopepuka

Kuyendetsa bwino kutentha,
Kutupa pang'ono kotsala,
Kuwonongeka kwa slag kolimba kosagonjetsedwa ndi asidi,
Kulemera kopepuka komanso kotetezeka ku chilengedwe,
Kukana kutentha bwino,
Kusintha kwa voliyumu yokhazikika kutentha kwambiri,
Mphamvu yamphamvu yamakina yotentha kwambiri.

Njira Yopangira Njerwa Yoteteza Silika Yopepuka

Njerwa Yopepuka Yotetezera Silika imayika zinthu zopangira ndi madzi mu chipangizo chopangira ulusi molingana ndi kuchuluka kwake kenako n’kusakaniza matope, kupanga matope kukhala njerwa kudzera mu makina kapena anthu ogwira ntchito. Kenako pukutani njerwa mpaka madzi otsalawo atakhala otsika kuposa 0.5%, zomwe zimaletsa kukula kwa voliyumu kuchokera ku kusintha kwa kristalo kwa SiO2 ndikuwotcha njerwa zooneka ngati zofewa kutentha kwambiri.

Kugwiritsa Ntchito Njerwa Yoteteza Silika Yopepuka

Njerwa zotetezera kutentha kwa silika zitha kugwiritsidwa ntchito mu uvuni wagalasi ndi chitofu chotentha, chipika chotetezera kutentha kwa silika chingagwiritsidwenso ntchito mu uvuni wa coke, uvuni wa carbon forging ndi ng'anjo zina zilizonse zamafakitale.
