Chiyambi cha Zamalonda
Chithandizo chapamwamba: Kukhuthala kwa filimu yamtundu wa zinc passivation ndi 8-15μm, mayeso opopera mchere ndi opitilira maola 72, ndipo mawonekedwe ake ndi amtundu wa utawaleza. Mukamagwiritsa ntchito trivalent chromium passivation, chitetezo cha chilengedwe chimakhala chabwino kwambiri.
Kuwongolera magwiridwe antchito: Kukana kwa dzimbiri ndikwambiri kuwirikiza katatu kuposa electrogalvanizing, ndipo ndikoyenera nyumba zakunja (monga ma awnings, sunshades) ndikuyika zida za bafa. Mphamvu yometa ubweya wa mawonekedwe a M5 mu mbale yachitsulo chosapanga dzimbiri ndi ≥35kN.
Zochitika zogwiritsira ntchito: unsembe wa zikwangwani zakunja, zitsulo zotayidwa pakhomo ndi kukonza zenera, zokongoletsera zamkati za ngalawa, ndi zina zotero, zomwe ziyenera kuganizira kukana kwa dzimbiri ndi kukongola.
Kufananiza kwakukulu ndi malingaliro osankhidwa

Malingaliro osankha:
Zinthu zachilengedwe: Kwa malo akunja kapena a chinyezi chambiri, kupaka utoto wa zinki kapena plating yakuda ya zinki ndizokonda; kwa malo owuma amkati, electroplating zinc ikhoza kusankhidwa.
Zofunikira pa katundu: Pazochitika zolemetsa kwambiri (monga milatho ndi makina olemera), zomangira zakuda za zinc zokhala ndi hexagonal zobowola mchira ziyenera kusankhidwa. Zomwe zili pamwamba pa M8 ziyenera kuyesedwa ma torque malinga ndi GB/T 3098.11.
Zofunikira pa chilengedwe: Electroplating zinki (yopanda chromium) ndiyovomerezeka m'mafakitale azachipatala ndi chakudya; trivalent chromium passivated color zinki plating kapena black zinki plating akhoza kusankhidwa ntchito wamba mafakitale.
Mafotokozedwe oyika:
Kuwongolera kuthamanga kwa kubowola kwamagetsi: zomangira za 3.5mm zobowola mchira zimalimbikitsidwa kuti zikhale 1800-2500 rpm, ndipo zomangira za 5.5mm zobowola mchira zimalimbikitsidwa kuti zikhale 1000-1800 rpm.
Kuwongolera kwa torque: Torque ya mawonekedwe a M4 ndi pafupifupi 24-28kg ・ cm, ndipo mawonekedwe a M6 ndi pafupifupi 61-70kg ・ cm. Pewani mapindikidwe a gawo lapansi chifukwa chomangika kwambiri.
