Ho roala ho roala ke thepa e thusang e koahetsoeng holim'a hlobo kapa mokokotlo, e phethang karolo ea bohlokoa ho ntlafatsa boleng ba holim'a li-castings. Litsebi tsa pele tsa mesebetsi ea matsoho tsa Chaena, lilemong tse fetang 3000 tse fetileng, li lokisitse 'me li atlehile ho sebelisa li-casting coating, li kenya letsoho haholo ntlafatsong ea theknoloji ea ho lahla.
Ka nts'etsopele ea tlhahiso le theknoloji, litlhoko tsa boleng ba ho lahla li ntse li eketseha letsatsi le letsatsi. Bakeng sa ho matlafatsa tlholisano ea lihlahisoa tsa bona, litsi tse ngata li inehela ho etsa lipatlisiso tsa liphahlo ka lebaka la mathata a tlhahiso.
E latelang, ka bokhutšoane mabapi le ho roala ho roala ha mathata a 'maloa.
Ntlha ea pele, litaba tse tiileng le matla a ho roala
Hona joale, ho roala ho sebelisoang bakeng sa lehlabathe le tlanngoeng ke resin ho hloka hore ho be le lintho tse tiileng tse phahameng le matla a phahameng, a bakoang haholo ke lintlha tse peli.
1. Ikamahanya le litšobotsi tsa hlobo ea lehlabathe
Nakong e fetileng, mofuta oa lehlabathe o metsi o sa pente, pente e sebelisoa feela bakeng sa mofuta o omileng oa letsopa. Ka lebaka la matla a letsopa lehlabathe omileng mofuta o tlaase haholo, 'me ho etsa castings bohlokoa kapa e khōlō castings, tlhokahalo ea barbotage eseng feela ho theha ho itšehla thajana lera,' me e hloka infiltration lahla barbotage holim'a tse latelang, molemo ka ho fetisisa. ho kenyelletsa lehlabathe la 3 ~ 4, etsa hore bokaholimo ba hlobo bo ntlafatsoe, ka hona, viscosity ea pente e ke ke ea phahama haholo, litaba tse tiileng ha li phahame haholo.
2. Nahana ka ho boloka matla, ho sireletsa tikoloho le ho fokotsa litšenyehelo tsa tlhahiso
Lijari tsa metsi tse sebelisoang ho koahela, haholo-holo metsi le lino tse tahang. Lilemo tse makholo a 20 70 ~ 80 nako, e sebelisitsoeng ha e hloke ho omisa kapa ho hotetsa, e ka etsa hore li-hydrocarbon tsa chlorine li fetohe, joalo ka dichloromethane, joalo ka sejari sa pente. Ka lebaka la chefo ea eona, tšusumetso e mpe ea eona tikolohong ha e fetoha mouoane sepakapakeng, le litšenyehelo tsa eona tse phahameng, hona joale ha e sebelisoe haholo.
Ea bobeli, lisebelisoa tse tala tse sebelisetsoang ho roala
Ho na le mefuta e mengata ea lisebelisoa tse tala tse sebelisoang ho roala, 'me li tla tlatselletsoa khafetsa motheong oa nts'etsopele ea indasteri ea thepa.
1. refractory aggregate
Refractory aggregate ke karolo e ka sehloohong ea ho roala, 'me boleng ba eona le khetho ea eona li na le tšusumetso e kholo holim'a phello ea tšebeliso ea ho roala. Ka nako e ts'oanang, ha re khetha kakaretso, re boetse re lokela ho etsa tlhahlobo e feletseng ea bohloeki ba indasteri le moruo.
2. mojari,
Lisebelisoa tse ka sehloohong tse sebelisoang ho roala liaparo ke metsi, joala le li-hydrocarbon tse chlorine. Hona joale, ka lebaka la ho nahanisisa ka theko le likarolo tsa tikoloho, tse sebelisoang haholo ho chlorine hydrocarbon e le mojari oa ho roala, ka kakaretso ke ho roala metsi le ho roala joala.
