Mokhoa o nepahetseng oa ho haha ​​oa refractory castable

Matsatsing ana, lisebelisoa tsa refractory tse bobebe li se li amohetsoe ke basebelisi ba bangata, mme ts’ebeliso ea lisebelisoa tse thibelang mocheso tse thibelang mocheso li ntlafalitse ho ba karolo ea lisebelisoa tsa refractory tse se nang sebopeho sa boima bo bobebe bo bobebe. Joale mokhoa oa ho sebelisa li-castable tse refractory ka nepo ts’ebetsong ea letsatsi le letsatsi? Kajeno ke tla u isa ho utloisisa:

1. The refractory castable haholo-holo e kopantsoe ke mixer ts’ebetsong ea sebele, ‘me ho kopanya ka letsoho ho thibetsoe. Ha ho se na mokhoa o mong, motsoako oa matsoho o tla amoheloa. Empa ho hloekisa fatše, ho lahla ho lokela ho ekeletsoa ka coagulant. Palo ea coagulant ke 3%. Haeba e le sebakeng sa marang-rang, o ka eketsa 5% ho kopanya ka ho lekana ebe o eketsa 8% PA80 glue bakeng sa ho kopanya ka potlako le tšebeliso e potlakileng, ho netefatsa hore e ka sebelisoa nakong ea metsotso e 10 ho feta.

2. Pele o tšela, qala ka ho roala ankora e tiileng ka lera la asphalt le pente. Ha botenya ba ho tšela bo ka hare ho 250mm, bo lokela ho tšeloa ho botenya bo boletsoeng ka nako e le ‘ngoe,’ me u thothomele ho fihlela bo kopane ka ho feletseng.

3. Sebelisa motsoako ho kopanya li-castable, tšela lesela ka har’a motsoako pele, ‘me u kenye 5-3% ea condensate. Fetola ho ya ka nako ya ho thatafatsa. Ka kakaretso, ha mocheso o le ≤25 ℃ ka hoetla, o ka eketsa 5%. Mohlala, ha mocheso oa karolo e tla hahuoa e le ≥30℃, o ka eketsa 3%. Tšela sebakeng se boletsoeng ho fihlela qetellong.

4. Ha u lahla li-castable tse boima bo bobebe le mocheso o phahameng, ho hlokahala hore u leke boleng ba ladle le palo ea linako tse jereng mojaro ka makhetlo a mangata. Ebang ke crane high-themperature castable ladle kapa portable ladle, e hlahloba likhoeli tse ling le tse ling tsa 2 1 Ea bobeli, hlahloba likarolo tsa bohlokoa bakeng sa mapetsong, deformation, ho ruruha, joalo-joalo.

5. Hlobo e tlameha ho hloekisoa pele ho hlobo ea inch, ‘me hlobo e tlameha ho kenngoa ka lera la oli nakong ea hlobo ea inch.

E ka holimo ke mokhoa o nepahetseng oa ho haha ​​​​mohaho oa refractory, ke tšepa hore ho tla ba molemo ho uena ha u sebelisa thepa ena ea refractory castable.
