Likhetho tsa lintho tse bonahalang tsa Nozzles
Likhetho tsa lintho tse bonahalang tsa Nozzles
Ha ho tluoa tabeng ea ho khetha thepa e nepahetseng bakeng sa nozzle, ho bohlokoa ho nahana ka lintlha tse kang ho tšoarella, ho lumellana le lik'hemik'hale, ho hanyetsa mocheso, le litšobotsi tse lakatsehang tsa ts'ebetso. A re hlahlobeng tse ling tsa likhetho tse sebelisoang hangata ho etsa li-nozzles.
1.Aluminium
Li-nozzles tsa aluminium li bobebe ebile li na le chelete e ngata, li etsa hore li tšoanelehe bakeng sa lisebelisoa tse sa hlokeng letho. Leha ho le joalo, ha li tšoarelle nako e telele joaloka lisebelisoa tse ling 'me li ka' na tsa apara habonolo ha li sebelisoa ka thepa e senyang haholo.
2.Silicon carbide
Li-nozzle tsa silicon carbide ke li-nozzles tsa sandblasting tse entsoeng ka thepa e kopantsoeng e kopanyang likaroloana tsa silicon carbide bakeng sa ho hanyetsa ka mokhoa o ikhethang oa ho apara ka thepa ea matrix bakeng sa ho ba thata le ho tšoarella, ho fana ka bophelo bo bolelele ba tšebeletso le ts'ebetso e ntlafetseng.
3.Tungsten Carbide
Tungsten carbide ke khetho e tsebahalang ka lebaka la boima ba eona bo ikhethang le ho hanyetsa ho roala. E khona ho mamella melapo e hlabang ea lebelo le phahameng 'me e loketse ho sebelisoa ka li-abrasives tse matla., empa e boima hobane e na le tšubuhlellano e kholo.
4.Boron Carbide
Boron carbide ke ntho e 'ngoe e tšoarellang haholo e tsejoang ka ho hanyetsa ho hoholo ha eona. E bobebe 'me e khona ho mamella litlamorao tsa lebelo le phahameng, e etsa hore e tšoanelehe bakeng sa lisebelisoa tse batloang ke sandblasting.
Mona ke papiso ea bophelo ba ts'ebeletso ka lihora tse fapaneng bakeng sa lisebelisoa tse fapaneng tsa li-nozzle mecheng ea litaba e fapaneng ea ho phatloha:
Thepa ea Nozzle | Sethunya sa tšepe / Grit | Lehlabathe | Aluminium oxide |
Aluminium oxide | 20-40 | 10-30 | 1-4 |
Motsoako oa silicon carbide | 500-800 | 300-400 | 20-40 |
Tungsten Carbide | 500-800 | 300-400 | 50-100 |
Boron Carbide | 1500-2500 | 750-1500 | 200-1000 |
Bophelo bona ba tšebeletsoba li fapana ho ipapisitse le lintlha tse fapaneng joalo ka maemo a ho phatloha, thepa ea mecha ea litaba e hlabang, moralo oa nozzle, le maemo a ts'ebetso. Ke habohlokoa ho nahana ka lintlha tsena ha u khetha thepa e loketseng ea nozzle bakeng sa lisebelisoa tsa sandblasting ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele.
Hopola ho hlahloba le ho boloka li-nozzle tsa hau khafetsa ho lelefatsa bophelo ba tsona le ho boloka ts'ebetso e tsitsitseng. Ho bohlokoa ho latela melaoana ha u etsa mesebetsi ea ho hloekisa.
