Ko nga rauemi mo te raima ko te SWRCH15A, ML15AL, ML15 ranei, me nga tira waro noa Q195 ...

Ko te matotoru o te kiriata konutea passivation tae ko 8-15μm, ko te whakamatautau rehu tote he nui atu i te 72 haora, a ko te ahua he kopere-tae. I te wa e whakamahia ana te paahitanga chromium trivalent, he pai te mahi tiaki taiao.

Ko te mahunga he hoahoa countersunk whiti, ka taea te huna ki roto i te mata whakauru kia mau tonu te mata. Ko te diameter moka drill he rite ki te diameter miro (pērā i te ST4.2 drill bit diameter 4.2mm), e ū ana ki te paerewa GB/T 15856.1-2002.

Na roto i te maimoatanga wai passivation pango kei roto te tote hiriwa (c2D), ka hangaia he paninga 10-15μm, ka neke atu i te 96 haora te whakamatautau rehu tote. Ko te whakakikorua konutea pango he pai ki te taiao e whakamahi ana i te chromium passivation trivalent, karekau he chromium hexavalent, ka whai ki nga paerewa RoHS.

Rainbow chromate passivation (c2C) i runga i te electrogalvanizing, paninga matotoru 8-15μm, whakamatautau rehu tote mo te neke atu i te 72 haora. I te wa e whakamahi ana i te tukanga passivation chromium trivalent, ka tutuki ki te RoHS te whakamarumaru taiao, a ko te ihirangi chromium hexavalent he ≤1000ppm.

Hanga o 1022A waro maitai, te pakeke mata tae HV560-750 i muri i te maimoatanga wera, me te pakeke matua tae HV240-450. Ko te mata he electro-galvanized ki te hanga i te paninga 5-12μm, e tutuki ana te paerewa GB / T 13912-2002, a ka tae te whakamatautau rehu tote ki nga haora 24-48 kaore he waikura ma.

He rite ano ki te pereti whakauru electrogalvanized, te whakamahi i te Q235 ranei Q355 waro maitai, pereti maitai matotoru 8-50mm, punga pae diameter 10-32mm, i roto i te rārangi ki GB / T 700 paerewa.

Q235 ranei Q355 waro maitai, te matotoru o te paraharaha maitai ko te nuinga o 6-50mm, te diameter o te pae punga ko 8-25mm, i roto i te rārangi ki GB / T 700 ranei GB / T 1591 paerewa.

Na roto i te maimoatanga wai passivation pango (c2D) kei roto te tote hiriwa, te tote parahi ranei, ka hangaia he kiriata passivation pango me te matotoru o te 10-15μm. He nui te utu engari he ahurei te ahua.

Whakamahia te paheketanga konutea tae (c2C), te matotoru paninga 8-15μm, ka taea e te whakamatautau rehu tote te neke atu i te 72 haora, te ahua karakara, te pai ake o te mahi anti-corrosion.

GB / T 882-2008 "Pin" paerewa, nominal diameter 3-100mm, rauemi ngā waro maitai, kowiri tira, me ētahi atu, electrogalvanized paparanga matotoru 5-12μm, i roto i te rārangi ki c1B c1A ranei whakaritenga muri maimoatanga.

Ko te tukanga whakawhiti o te konutea tae (c2C) ka tangohia, ko te matotoru o te paninga he 8-15μm, a ko te parenga waikura o te whakamatautau rehu tote he nui atu i te 72 haora, he mahi anti-corrosion me nga mahi whakapaipai.
