Izidingo zokwelashwa kwesihlabathi ngesikhathi sokuphonsa isihlabathi

Enqubweni yokuphonsa isihlabathi, kunezidingo ezibalulekile zokuphatha isihlabathi ukuze kuqinisekiswe ukuthi isihlabathi kanye nokubunjwa kwekhwalithi ephezulu kuyatholakala. Nazi ezinye izidingo ezijwayelekile:

1. Isihlabathi esomile: Isihlabathi kufanele some futhi akufanele sibe nomswakama. Isihlabathi esimanzi sizodala ukukhubazeka ebusweni bokubunjwa, futhi kungase kubangele izinkinga ezifana ne-porosity kanye ne-warping.

2. Isihlabathi esihlanzekile: isihlabathi kufanele sihlanzwe ukuze kukhishwe ukungcola nezinto eziphilayo. Ukungcola kanye nezinto eziphilayo kuzoba nomthelela omubi kwikhwalithi yokubunjwa futhi kungase kubangele ukukhubazeka ebusweni besikhunta sesihlabathi.

3. I-granularity yesihlabathi efanelekile: i-granularity yesihlabathi kufanele ihlangabezane nezidingo ezithile zokuqinisekisa izinga eliphezulu lesihlabathi namandla esikhunta. Izinhlayiya zesihlabathi ezimaholoholo noma ezincane kakhulu zingaba nomthelela omubi ekubumbeni nasekuthululeni.

4. I-viscosity enhle yesihlabathi kanye ne-plasticity: i-viscosity kanye ne-plasticity yesihlabathi kubalulekile ekwakhekeni kwesihlabathi esiqinile. Izinto zesihlabathi kufanele zibe nokuhlangana okufanele kanye nepulasitiki ukuze kugcinwe ukwakheka nokuzinza kwesikhunta sesihlabathi.

5. Inani elifanelekile lezithasiselo zesihlabathi: Ngokuya ngezidingo ezithile zokuphonsa, kungase kudingeke ukuba kwengezwe ama-agent asizayo esihlabathini, njengama-binders, ama-plasticizer, ama-pigments, njll. Izinhlobo namanani alezi zithako kudingeka zilungiswe ukuze ukuhlangabezana nezidingo ezithile zokusakaza.

6. Ukulawulwa kwekhwalithi yesihlabathi: Enqubweni yokuthenga nokusebenzisa isihlabathi, ukulawulwa kwekhwalithi nokuhlolwa kuyadingeka. Qinisekisa ukuthi ikhwalithi yesihlabathi isezingeni nokuthi isihlabathi esinesici noma esingcolile asisetshenziswa.

7. Ukugaywa kabusha kwesihlabathi: Lapho kungenzeka khona, ukugaywa kabusha kwesihlabathi nokusetshenziswa kabusha kufanele kwenziwe. Ngokwelashwa nokuhlolwa okufanele, isihlabathi esilahlwayo sigaywa kabusha, kuncishiswe izindleko kanye nokumoshakala kwezinsiza.

Kumele kuqashelwe ukuthi izidingo ezithile zokuphatha isihlabathi zingase zihluke kuye ngokuthi uhlobo nempahla yokubunjwa, indlela yokulungiselela kanye nokugeleza kwenqubo yesikhunta sesihlabathi. Ngakho-ke, ohlelweni lokuphonsa, kufanele lusekelwe esimweni esithile ukuze kuqinisekiswe ukuthi ukwelashwa kwesihlabathi kuhlangabezana nezidingo.
