Isitovu sokukhuphela kwiziko leziko

Isitovu sokukhuphela kwiziko leziko

Izibonelelo zeMveliso: ukumelana nobushushu obuphezulu, ukumelana nokhukuliseko lomhlaba, amandla aphezulu esakhiwo, ukuthembeka okuhle, uzinzo olomeleleyo lokukhwankqiswa kobushushu, ubomi benkonzo ende, njl.

Isicelo seMveliso: Izitshisi zecandelo lezolimo ezinje ngeekheram zokwakha kunye nokusetyenziswa kweekeramiki zemihla ngemihla. Ukutshintsha kobushushu rhoqo, iimfuno zamandla aphezulu, ukunxiba ukumelana,

Ingcaciso yeMveliso

Isitshisi sikwabizwa ngokuba sisitshisi, esisisixhobo sokutsha kwizibuko legesi kwisitovu sepetroli seshishini, kwaye sinokuqondwa “njengombhobho womlilo”. Ngokwesiqhelo ibhekisa kwinxalenye yomzimba yesixhobo sokutsha, esine-petroli, ukungena komoya kunye nomngxunya wokutshiza, odlala indima yokuhambisa ipetroli kunye nokutsha komoya kunye nokutshiza ngendlela ethile yokutsha. Zimbini iinkqubo ezisetyenziswayo zokuvelisa izitena, izitena zokwakha izitena kunye nolungelelwaniso lokudibanisa. Izitena zokutshisa ezisetyenziswayo ngoku zenziwe ngezinto ezilahlayo kwaye zishukunyiswa ngaxeshanye ngumbumba okhethekileyo.

Imisebenzi yezitena ezitshisayo eziko yile:

1. Fudumeza isibane kwisitena sokutshisa sisebenzise iqondo lobushushu ukuze ucofe umlilo ngokukhawuleza;

2. Gcina iqondo lobushushu eliphezulu kwizitena zokukhulisa inkqubo yokutsha kunye nokuphepha ukubetha okanye ukuphazamiseka komlilo;

3. Cwangcisa imilo yedangatye ukuhlangabezana neemfuno zenkqubo yokufudumeza;

4. Ukuqhubeka nokuxuba amafutha kunye nomoya.

Ngokwezixhobo ezahlukeneyo, yahlulwe yangamacandelo amane: i-corundum, i-aluminium ephezulu, i-silicon carbide, kunye ne-mullite. Ngokweemfuno, izixhobo ezahlukeneyo zikhethwe ngokudibeneyo kunye nomgubo, kunye nezongezo ezihlanganisiweyo zongezwa. Aluminium phosphate isetyenziswa njengesibopheleli. Ukungcangcazela kwenziwa kwaye kubhakwa. Yiba. ,
