Kodi pamafunika matope angati kuti timange njerwa?

Njerwa zaumbali ndi zinthu zofunika kwambiri popanga zophikira mafakitale ndi uvuni. Musanakhazikike njerwa, konzekerani slurry yomwe agwiritsa ntchito. The pazipita tinthu kukula kwa slurry sayenera upambana 20% ya zimfundo zomangamanga. Mphamvu zakuthupi ndi mankhwala zamatope ziyenera kufanana ndi mtundu wa njerwa zomwe zimatsitsimula. Mukamagula njerwa zopangira, ndibwino kusankha wopanga kuti akonze matope oyeserera kuti asasakanikirane.

Procedures: Njira zosakira matope

Zomwe zimafunikira pakukonzekera matope oyenera kuyenera kutengera mtundu wa zomangamanga, ndipo kusasinthasintha ndi zinthu zamadzimadzi za slurry ziyenera kutsimikizika potengera mayeso. Nthawi yomweyo, onetsetsani ngati zomangamanga (nthawi yolumikiza) ya grout ikukwaniritsa zofunikira pamiyala. Nthawi yolumikizana ya grout imadalira pazinthu komanso kukula kwa chinthu chosakanikirana, nthawi zambiri sayenera kupitirira mphindi 2, ndipo kuchuluka ndi kusasinthika kwama grout osiyanasiyana amasankhidwa malinga ndi mtundu wa zomangamanga.

Kutsimikiza kwa kusasunthika kwa matope kudzachitika malinga ndi zofunikira za mafakitale apadziko lonse lapansi “Njira Yoyeserera Yosagwirizana Pamatope”. Nthawi yolumikizana ndi slurry imatsimikiziridwa molingana ndi zofunikira za mafakitale apadziko lonse lapansi “Njira Yoyesera Nthawi Yotsalira Yamatope”.

Pali njira ziwiri zokonzera matope: kuphatikiza kwachilengedwe kwa madzi ndi kuphatikiza kwa mankhwala. Pomanga nyumba zamatabwa ndi ma kilns, ambiri aiwo amapangidwa ndi mankhwala, ndipo coagulant yofananira imawonjezeredwa. Amadziwika ndi liwiro lolimba lolimba, kulumikizana kwakukulu, komanso kulimba pakakhala kutentha. Komabe, mutatha kugwiritsa ntchito matope omata amadzi, madzi otentha kwambiri mu uvuni amavutitsa, matope omanga matope ndiosavuta kukhala osweka, ndipo zomangamanga sizolimba. Kuphatikiza apo, slurry ya refractory yokonzedwa tsiku lomwelo iyenera kugwiritsidwa ntchito tsiku lomwelo.

2: Njira yowerengera yogwiritsira ntchito matope

Pakadali pano, palibe njira yabwino yoyezera kufunika kwa matope oyaka moto m’ng’anjo yonse yamafuta. Chifukwa cha mitundu ingapo yama ng’anjo yamakampani ndi njerwa, ndizotheka kupanga njerwa zapadera zofananira. Njerwa zosakhazikika kapena zomanga ndizosiyana, ndipo kuchuluka kwa matope omwe amagwiritsidwa ntchito pomanga njerwa limodzi pakhoma la ng’anjo ndiyenso. Pansi pa ng’anjo ndi zosiyana. Pakadali pano, maziko ogwiritsira ntchito dothi losunthira mu bajeti kapena kuyerekezera kwa uinjiniya wamoto ndi njerwa zomwe zimagwiritsidwa ntchito pomanga makoma amoto. Kuphatikiza apo, kutchulidwenso kulumikizana ndi matope omanga, omwe ndi gawo loyesa kuyeza matope omwe amagwiritsidwa ntchito mu njerwa zokhazikika. Mitengo yamatabwa yamatabwa iyenera kukhazikitsidwa koyamba. Msoko wa phulusa woyamba ndi wochepera 1mm, msoko wachiwiri wa phulusa ndi wochepera 2mm, ndipo msoko wachitatu wa phulusa ndi wochepera 3mm. Pa mitundu itatu ya matope olumikizirana matope, ziwalo zachiwiri zamatope zimagwiritsidwa ntchito popanga njerwa zadothi kapena njerwa zapamwamba za aluminiyamu.

Mwachitsanzo, kuwerengera kuchuluka kwa matope osakira omwe amafunikira zidutswa 1000 za njerwa zapamwamba zopangira alumina, njira yowerengera iyenera kudziwika koyamba: a = matope omata olowa (2mm) B = kukula kwa njerwa mbali imodzi (T-3 kukula 230 * 114 * 65)

C = mtundu wa matope omwe amagwiritsidwa ntchito (matope ambiri ndi 2300kg / m3) d = kuchuluka kwa matope ofunikira njerwa iliyonse. Pomaliza, kugwiritsa ntchito matope d = 230 * 114 * 2 * 2500 = 0.13kg (kugwiritsidwa ntchito pa block). Kugwiritsa ntchito njerwa zokwana 1000 zokhala ndi alumina okwera pafupifupi pafupifupi 130kg za zotchinga. Njira yowerengera ndi njira yowerengera, ndipo momwe amagwiritsidwira ntchito ayenera kukhala opitilira 10% yazambiri.
