Bubble-resistant tubali

An kuma kira tubalin da ke ɗauke da sinadarin phosphate mai ƙarfi na aluminium wanda ake kira tubalin da ke da tsayayyen takin. Tubalan da ke iya jurewa da Phosphate wani nau’in kayan ƙyama ne, waɗanda ke da ƙima mai ƙarfi bauxite clinker ko m phosphoric acid bayani a matsayin babban kayan albarkatun ƙasa, ko maƙalar phosphate na aluminium, Bayan an matse shi kuma ya ƙera shi da injin bushewa, ana kula da shi da zafi. a 400-600 ℃ don yin samfuran ƙuntatawa masu alaƙa da sinadarai. An haɗa shi da tubalin. Don guje wa manyan raguwa yayin amfani da samfurin a yanayin zafi mai zafi, yawancin abubuwan da ake buƙata suna buƙatar gabatar da kayan haɓaka haɓaka dumama, kamar kyanite, sillimanite, pyrophyllite, da carbide silicon. Sintered tare da manyan alumina tubalin da yumbu, juriya ga peeling ya fi kyau, amma zafin zafin yana ƙasa da juriya, don haka ana buƙatar ƙaramin adadin fused corundum, mullite, da sauransu don ƙarfafa matrix. Dangane da phosphoric acid da phosphoric acid masu jurewa bulo, tsayayyun tubalin da aka yi da manyan tubalin alumina ta hanyar fasaha ta musamman da ƙari na sunadarai sun inganta haɓakar abrasion da zazzabi mai laushi, mafi girma fiye da manyan tubalin alumina, ƙarfi mai kyau, saurin sanyaya da saurin juriya mai zafi, Mai tsayayya da lalacewar sunadarai da abrasion. Kamanninsa ya fi na manyan tubalin alumina a cikin siminti rotary kilns.

Ayyukan fasaha:

(1) Babban aikin juriya na zafin jiki yana da kyau, zafin zazzabi ya fi digiri 1770, yana iya tsayayya da yanayin zafi mai ɗorewa, kuma sauye -sauye a yanayin zafi ba su da babban tasiri.

(2) Kyakkyawan kwanciyar hankali na zafi, juriya ga saurin sanyi da saurin zafi, kuma babu delamination ko peeling ƙarƙashin canje -canjen zafin jiki.

(3) Juriya na sinadarai, babu fashewa da peeling da zai faru a cikin yanayin Co a zazzabi na 400-600 ° C.

(4) Kyakkyawan juriya da ƙarfi mai ƙarfi.

An gane tubalin Phosphate a matsayin manyan bulo na rufi mai inganci don murhun siminti da murhun lemun tsami.

Akwai manyan tubalin alumina guda biyu na phosphate: ɗaya shine tubalin allurar phosphate (wanda ake kira tubalin phosphate), ɗayan kuma shine tubalin aluminna mai ɗauke da sinadarin phosphate (wanda ake kira tubalin da zai iya sawa).

Bricks na phosphoric suna amfani da maganin phosphoric acid tare da maida hankali daga 42.5% zuwa 50% a matsayin mai ɗaurewa, kuma tarin shine bauxite clinker calcined a zazzabi sama da 1600 ° C a cikin injin juyawa. Yayin amfani da bulo, acid phosphoric yana amsawa tare da madaidaicin bauxite foda a cikin bulo don yin aiki tare da yumɓu mai ƙyalƙyali, kuma a ƙarshe ya zama mai ɗaurin gindi wanda ya ƙunshi cristobalite aluminum orthophosphate. Bricks masu jurewa suna amfani da sinadarin phosphoric na masana’antu da aluminium hydroxide na masana’antu don shirya maganin allurar phosphate azaman mai ɗauri. Matsayinsa na molar shine Al2O3: P2O5 = 1: 3.2. Adadin da aka yi amfani da shi iri ɗaya ne da na tubalin phosphate. A yayin amfani da tubali, kamar phosphate, an ƙirƙiri wani mai ɗauri dangane da cristobalite-type aluminum orthophosphate.

Bubbugar phosphate sun dace da bakin kiln na yankin canza wuri na murjani na juyawa da sauran sassan inda tubalin yake da sauƙin faɗuwa, kuma yana da fa’ida ga yankin harbi. Hakanan ana amfani da shi a cikin injin keken injin, kiln lemun tsami, masana’antar carbon carbon rotary kilns, da sauransu.

Ayyukan samfur: Yana da halaye na babban ƙarfin matsa lamba a cikin zafin jiki na ɗakin, kwanciyar hankali mai ɗorewa mai ɗorewa, zazzabi mai taushi mai nauyi, madaidaicin madaidaici, ƙarar girma, da juriya mai kyau.
