Njerwa Yopepuka ya Fireclay

Kufotokozera Kwachidule:

Njerwa zopepuka za fireclay zimapangidwa ndi magulu apamwamba opepuka ndipo zimakhala ndi ma micropores ambiri.High, otsika kachulukidwe chochuluka, ang'onoang'ono matenthedwe madutsidwe, mphamvu zabwino zopulumutsa ndi matenthedwe kutchinjiriza zotsatira, apamwamba ndi mtengo wotsika.

Njerwa zopepuka zamoto zimakhala ndi mawonekedwe opanda mapindikidwe, opanda poizoni komanso osanunkhiza, zomangamanga zotetezeka komanso zosavuta.Ndizinthu zabwino zopangira khoma, kutenthetsa kutentha ndi chipinda;sizingangowonjezera kutentha, kuchepetsa nthawi yotentha, komanso kuchepetsa mafuta.Ndipo ili ndi zotsekemera zomveka bwino komanso kuyamwa kwamawu, chomwe ndi chisankho chabwino kwambiri pazida zopulumutsa mphamvu komanso zoteteza chilengedwe.

Mawonekedwe

1. Kulemera kopepuka: mphamvu youma ya njerwa yopepuka ndi 500-700Kg/m*3 yokha, yomwe ndi 1/4 ya konkire wamba.
, 1/3 dongo, 1/2 ya chipika dzenje, chifukwa kachulukidwe ake chochuluka ndi chochepa kuposa madzi, amene amadziwika kuti aerated konkire akuyandama pamwamba pa madzi, kugwiritsa ntchito mankhwalawa pomanga akhoza kuchepetsa kudziletsa kulemera. nyumbayo ndi kuchepetsa kwambiri kulemera kwa nyumbayo.ndalama zonse.
2. Kuteteza kutentha ndi kusungunula kutentha: Panthawi yopangira konkire ya aerated, ma pores ang'onoang'ono amapangidwa mkati, ndipo poreswa amapanga mpweya wosanjikiza muzinthu, zomwe zimathandizira kwambiri kuteteza kutentha ndi kutentha kwa kutentha, kotero kuti kutentha kwa matenthedwe. konkire ya aerated ndi 0.11- 0.16W/MK.Mphamvu yotchinjiriza yamafuta ndi nthawi 5 kuposa njerwa zadongo ndi nthawi 10 kuposa konkriti wamba.
3. Mayamwidwe amawu ndi kutsekereza mawu: Kapangidwe ka porous konkire yopangidwa ndi mpweya imapangitsa kuti ikhale ndi mayamwidwe abwino a mawu komanso kutsekereza mawu, zomwe zimatha kukupatsirani mpata wamkati wosanjikiza mpweya.Akupatseni malo okhala abata komanso omasuka.
4. Mtengo wocheperako pang'ono: chifukwa chogwiritsa ntchito mchenga wamtsinje wapamwamba kwambiri ndi malasha opukutidwa ngati zida za siliceous, mtengo wa shrinkage ndi 0.1--0.5mm/m okha, ndipo kutsika kochepa kwazinthu zapamwamba kumatsimikizira kuti khoma lanu. sichidzasweka.
5. Kusalowa m'thupi: Kapangidwe ka pore kwa mankhwalawa kumapangitsa kuti pakhale vuto la capillary, ndipo imatenga madzi pang'onopang'ono ndikupangitsa chinyezi pang'onopang'ono.Nthawi yofunikira kuti madzi amwemomwemo kuti amwe madzi kuti achuluke ndi nthawi 5 kuposa njerwa zadothi.
6. Kuteteza chilengedwe: Njira zopangira, zoyendetsa ndi zogwiritsira ntchito ndizopanda zowononga, zimapulumutsa mphamvu komanso zimachepetsa kugwiritsa ntchito, komanso ndi zomangira zobiriwira komanso zoteteza chilengedwe.
7. Kusagwedezeka kwa chivomezi: Nyumba yomanga yomweyi imagwiritsa ntchito njerwa zopepuka kuti ziwongolere chivomerezi kuposa njerwa zadothi.
8. Kukhalitsa: Mphamvu ya nthawi yayitali ya konkire yopangidwa ndi mpweya imakhala yokhazikika.Pambuyo pa chaka chimodzi chodziwika ndi mlengalenga wa chitsanzocho, mphamvuyo yawonjezeka ndi 25%, ndipo imakhala yokhazikika patatha zaka khumi.
9. Processability: kulemera kuwala, zosiyanasiyana zazikulu, zosavuta misomali, kubowola, kuwaza, macheka, kukonza ndi kuyala mapaipi, ndi ntchito mapaipi kukula pakhoma, amene angathe kukonza mwachindunji makabati atapachikidwa, zoziziritsira mpweya, hoods osiyanasiyana, etc. inu Kuyika kwa madzi ndi magetsi, kukongoletsa kunyumba kumabweretsa kumasuka.
10. Refractory: Mlingo wa refractoriness ndi digiri, yomwe ndi kalasi yoyamba refractory zinthu.Kukana moto kwa midadada 100mm wandiweyani kumatha kufika mphindi 225, ndipo kukana kwa moto kwa midadada 200mm kumatha kufika mphindi 480.

Njira Yopangira

1.Kuwongolera khalidwe lazinthu zakuthupi kuphatikizapo kuyezetsa thupi ndi mankhwala.
2.Kuphwanya ndi kugaya zinthu zambiri zopangira.
3. Malinga ndi kasitomala deta pepala chofunika kusakaniza Raw Material.
Kukankhira kapena kuumba njerwa yobiriwira kumadalira zosiyanasiyana zopangira ndi mawonekedwe a njerwa.
4.Umitsani njerwa pa dryer kiln.
5.Ikani njerwa mu ng'anjo yowotcheramo kuti zipse ndi kutentha kwambiri kuyambira 1300-1800 deg.
6.Dipatimenti yoyang'anira khalidwe idzayendera njerwa zomalizidwa mwachisawawa.
