Chithandizo cha pamwamba pa pulley

Thepulley yonyamula katundupamwamba pake pakhoza kukonzedwa m'njira zosiyanasiyana malinga ndi malo ndi zochitika zinazake. Njira zochiritsira zimagawidwa m'mitundu iyi:

1. Gkuyeretsa

Galvanization ndi yoyenera zida zamafakitale zomwe zimagwiritsidwa ntchito m'makampani opepuka, zida zamagetsi, mafakitale amagetsi, makina aulimi, makampani oteteza dziko, ndi zina zotero. Monga njira yodziwika kwambiri yochizira pamwamba pa pulley pakadali pano, ndi yoteteza chilengedwe ndipo ili ndi makhalidwe otsatirawa poyerekeza ndi galvanizing yachikhalidwe:

(1) Musagwiritse ntchito cyanide ya poizoni, kuti madzi otayira omwe apangidwawo athe kuchiritsidwa mosavuta.

(2) Chophimbacho chili ndi makristalo abwino, kuwala bwino, ndipo mphamvu yobalalitsira ndi mphamvu yophimba kwambiri zili pafupi ndi njira yothetsera cyanide, yomwe ndi yoyenera kupangira zigawo zokhala ndi mawonekedwe ovuta pogwiritsa ntchito electroplating.

(3) Njira yokhazikika yopangira ma plating ndi ntchito yabwino

(4) Zipangizo sizingawonongeke ndi dzimbiri

(5) Mtengo wotsika

 

2. Chrombale

Chromamiyamu yokongoletsera imagwiritsidwa ntchito kwambiri m'magalimoto, njinga, zida zapakhomo, zida zapakhomo, zosinthira zida, zida zamakanika ndi zida zina ndi zinthu zina. Kukongoletsa kwa Chromium pogwiritsa ntchito ukadaulo wa nickel, nickel chromium kuti zitsimikizire mtundu wa malonda. Pamwamba pake ndi siliva woyera, wokongoletsedwa ndi chrome yokhala ndi kukana dzimbiri kwamphamvu komanso kukongoletsa bwino, wokhala ndi coefficient yayikulu yowunikira.

3. Chophimba cha rabara

Chitoliro chachitsulo chachitsulo chimakutidwa ndi rabala, kenako chimapangidwa kuti chikhale pulley yophimba rabala. Poyerekeza ndi pulley wamba, pulley yophimba rabala imakhala ndi mawonekedwe otanuka, osagwirizana ndi kutopa, osagwirizana ndi asidi ndi alkali, osagwirizana ndi mafuta (NBR), osagwirizana ndi kutentha komanso osagwirizana ndi dzimbiri ndi zina zotero; Zipangizo zopangira ndi zomatira zochokera kunja zimagwiritsidwa ntchito. Rabala yachilengedwe ndi NBR zimagwiritsidwa ntchito kwambiri. Mitundu yakuda, yobiriwira komanso imvi yopepuka ndi yomwe imalimbikitsidwa.

4. Chophimba cholimba cha chrome

Chromium yolimba imadziwikanso kuti chromium yosatha, mankhwalawa amatha kuwonjezera kuuma kwa pamwamba pa pulley, kusintha kukana kuvala, kutentha ndi kukana dzimbiri, amagwiritsidwa ntchito mu nkhungu yamakina, nkhungu ya pulasitiki, ma valve osatha dzimbiri, kusindikiza, kukonza ndi kuyeza ma pulley ndi nsalu ndi mapepala, pamwamba pake ndi siliva woyera.
