Sei chisote kana chinodhonza chichida kuita phosphate blackening?
The PULLEY chikamu chemhando yehubhu, uye zvinhu zvacho zvinowanzoita simbi yakakandwa. Iyo nzira yekugadzira inowanzoenderana nekukanda uye kuforoma. Naizvozvo, zvigadzirwa zvepulley zvisina kurapwa kwepamusoro zvinowanzoita maburrs pamusoro uye zvinogona kukuvadza maoko ako. Vanogonawo kuita ngura mushure mekushandiswa kwenguva refu munzvimbo ine hunyoro. ngura chiitiko.
Parizvino, iyo inowanzo shandiswa pamusoro pekurapa kwepulleys ndeye phosphating uye blackening. Maitiro acho kubvisa mafuta uye ngura - kucheneswa kwemvura - kugadzirisa kwepasi - phosphating - kuchenesa mvura - chromate kurapwa - kuomesa - girizi kana dhayi kurapwa:
Mushure mekunge pulley yave phosphated uye yakasviba, pulley ine zviri nani zvese-dema chitarisiko. Chinhu chakakosha ndechekuti mushure mekunge pulley iri phosphated uye yakasviba, hazvisi nyore kuita ngura. Upenyu hwebasa hwepulley hunowedzera zvakanyanya, izvo zvinogona kunyatsobatsira vatengi kuderedza mari.
