1. Sebopeho le khetho ea thepa

(1) Phofo e sa sebelisoeng e lahliloeng ke foam e na le litlhokahalo tse tharo tsa bohlokoa bakeng sa khetho ea phofo e qhekellang: Pele, boholo ba phatsa ea phofo e sa ts'oanelang e lokela ho ba mahoashe, empa haeba e le mahoashe haholo, khanyetso ea lehlabathe ea seaparo e tla ameha, mme lehlabathe le lwantshang thupa le tla elwa hloko. Le e phahameng permeability moea, khetha phatsa boholo ba 0.08 ～ 0.071mm (180/200 letlooeng); ea bobeli, ho potoloha sebopeho sa phofo e hanyetsang, ho betere, phofo e chitja e na le moea o kenang hantle; ea boraro ke hore phofo e hanyetsang e na le moea o kenang hantle; Lihlahisoa tsa pyrolysis tsa polasetiki ea foam li tlameha ho ba le matla a adsorption. E le hore ho ntlafatsa tshebetso ka kakaretso ea barbotage, phahameng ea alumina bauxite clinker phofo (phatsa boholo 0.08mm) le mica phofo (phatsa boholo 0.071mm) ba khethoa e le phofo refractory. Phofo e phahameng ea alumina bauxite e na le sebopeho se nang le lithollo tse lekaneng, se ka ntlafatsang moea o kenang oa seaparo le matla a adsorption a lihlahisoa tsa foam pyrolysis; phofo ea mica ke silicate e khabisitsoeng e tsoang mohahong, e sa keneleng mocheso ebile e sa keneng, ts'ebetso ea ho kenya lintho hantle, ho tenyetseha hantle le ho tenyetseha, ho eketsa karolo e itseng ea phofo ea mica ho bararo ho ka ntlafatsa tšireletso, ho kenella hoa moea o phahameng le ho sinterability ea ho roala.
(2) Binder EPC barbotage binder ke karolo ea bohlokoa ea barbotage ea. Ha e fane feela ka matla le ho ata ha seaparo, empa e ama le ho kenella hoa moea le ho emisoa ha seaparo. Hangata, ho kopana ha binder e sa tloaelehang le binder ea manyolo ha ho netefatse feela matla a ho roala ka mocheso oa mohatsela le mocheso o phahameng, empa hape e ntlafatsa katleho ea moea oa seaparo. Ka lebaka la molumo o moholo le lebota le tšesaane la nyeoe ea phetisetso le nyeoe ea phetisetso, molemong oa ho netefatsa ho tiea, matla le moea o kenang molemong oa ho roala, mefuta e meraro ea likhomaretsi, latex e tšoeu, starch ea starch le phofo ea RSF e nang le phello ea metsi. khethiloe.

Ka lebaka la boholo ba mahoashe a phofshoana le ponahalo e kholo ea seaparo, ha ho lokisoa liaparo, Lithium bentonite le attapulgite li sebelisoa e le mahlahana a emisang. Lithium bentonite le attapulgite li ka theha sebopeho sa marang-rang se nang le mahlakore a mararo ka metsing. Motsoako oa tse peli o ka ntlafatsa ho fanyeha ha seaparo le ho ntlafatsa rheology le ts'ebetso ea ts'ebetso ea ho roala.
