Kutheni isithungu okanye isitsali sifuna ukwenziwa mnyama ngephosphate?

I I-PULEY yinxalenye yodidi lwe hub, kwaye imathiriyeli ngokuqhelekileyo iyintsimbi. Inkqubo yokwenziwa kwemveliso ngokubanzi isekelwe kwi-casting kunye ne-forging. Ke ngoko, iimveliso zepulley ngaphandle konyango lomphezulu ziqhelekile kwi-burrs kumphezulu kwaye zinokulimaza izandla zakho. Zisenokukhula umhlwa emva kokusetyenziswa ixesha elide kwindawo efumileyo. umhlwa isenzeko.

Okwangoku, unyango oluqhelekileyo olusetyenziswa phantsi kweepulleys yi-phosphating kunye ne-blackening. Inkqubo yokususwa kwe-oyile kunye nomhlwa - ukucocwa kwamanzi - ukulungiswa komphezulu - i-phosphating - ukucocwa kwamanzi - unyango lwe-chromate - ukomisa - igrisi okanye unyango lokudaya:

Emva kokuba i-pulley yenziwe i-phosphated kwaye ibe mnyama, i-pulley inembonakalo engcono kakhulu emnyama. Into ebalulekileyo kukuba emva kokuba i-pulley i-phosphated kwaye imnyama, akulula ukugqwala. Ubomi benkonzo ye-pulley yandiswa kakhulu, enokuthi incede ngokufanelekileyo abathengi ukunciphisa iindleko.
