Setene sa boapeelo bakeng sa sebopi sa indasteri

Melemo ea lihlahisoa: ho hanyetsa mocheso o phahameng, ho hanyetsa khoholeho ea mobu, matla a phahameng a sebopeho, botšepehi bo botle, botsitso bo botle ba mocheso, bophelo bo bolelele ba ts’ebeletso, jj.

Kopo ea lihlahisoa Khafetsa liphetoho tsa mocheso, litlhoko tse phahameng tsa matla, ho roala,

Tlhaloso ea Sehlahisoa

Setsi sa boapeelo se boetse se bitsoa boapeelo, e leng sesebelisoa sa ho tuka ha boema-kepe ba khase setofong sa mafura sa indasteri, mme se ka utloisisoa e le “nozzle ea mollo”. Hangata e bua ka karolo ea ‘mele ea sesebelisoa sa mollo, se nang le pompo ea peterole, lesoba la moea le lesoba la spray, le bapalang karolo ea ho aba mafura le moea o tšehetsang mollo le ho o fafatsa ka tsela e itseng bakeng sa mollo. Ho na le lits’ebetso tse peli tse sebelisoang hangata tsa tlhahiso ea litene, moetso oa litene o hahelletsoeng hape o entsoe ka bohlokoa. Litene tsa boapeelo tse sebelisoang hajoale li entsoe ka li-castable tse haelloang mme li sisinngoa ka nako e le ‘ngoe ka hlobo e khethehileng.

Mesebetsi ea litene tsa boapeelo ke hore:

1. futhumatsa mafura ka setene sa boapeelo ho a etsa hore ho be bonolo ho hotetsa le ho chesa kapele;

2. Boloka mocheso o itseng o phahameng setene sa boapeelo ho tsitsisa ts’ebetso ea ho tuka le ho qoba ho phatloha kapa ho sitisoa hoa ho tuka;

3. Hlophisa sebopeho sa lelakabe ho fihlela litlhoko tsa ts’ebetso ea ho futhumatsa;

Ho ntšetsa pele mafura le moea.

Ho latela lisebelisoa tse fapaneng, e arotsoe ka mekhahlelo e mene: corundum, aluminium e phahameng, silicon carbide le mullite. Ho latela litlhoko, ho khethoa lisebelisoa tse fapaneng e le kakaretso le phofo, ‘me ho kenyelletsoa likhakanyo tse kopaneng. Aluminium phosphate e sebelisoa e le binder. Ho thothomela ho thehoa le ho besoa. Eba. ,
