I-Spring Pad Ecwengisisiwe Enamandla Aphezulu

Isithombe Esifakiwe Se-Spring Pad Ecwengisisiwe Enamandla Aphezulu

Incazelo emfushane:

Ukusetshenziswa kwe-spring washer
1. Ukuze kuxhunywe amabhawodi ajwayelekile, ama-washer ayisicaba kufanele abekwe ngaphansi kwekhanda lebhawodi kanye ne-nut ukuze kwandiswe indawo ethwala ingcindezi.
2. Kuma-bolts nama-anchor bolts aklanyelwe izidingo zokulwa nokukhulula, kufanele kusetshenziswe i-nut noma i-spring washer yedivayisi yokulwa nokukhulula, futhi i-spring washer kumele ibekwe eceleni kwe-nut.
3. Ukuze kuxhunywe amabholidi anemithwalo enamandla noma izingxenye ezibalulekile, ama-spring washer kufanele abekwe ngokwezidingo zomklamo, kanti ama-spring washer kumele abekwe eceleni kwe-nut.
4. Kuma-I-beams kanye nezinsimbi zesiteshi, kufanele kusetshenziswe ama-washer athambekele lapho kusetshenziswa ukuxhumana kwe-integrated plane ukuze kwenziwe ubuso bokuthwala be-nut kanye ne-bolt head buqonde ngqo kusikulufu.

Inqubo yokwelapha ubuso

1. Ukwenziwa mnyama (oluhlaza okwesibhakabhaka) Izinamathiseli ezizokwenziwa mnyama zifakwa ethangini lesisombululo (145±5 °C) se-sodium hydroxide (NaOH) kanye ne-sodium nitrite (NaNO2) oxidant ukuze kufudunyezwe futhi kufakwe i-oxidize, ukuze ubuso besinamathiseli sensimbi bukhiqize ifilimu ye-magnetic ferric tetroxide (Fe3O4), ubukhulu ngokuvamile bungu-0.6-0.8μm, mnyama noma luhlaza okwesibhakabhaka-mnyama. Izindinganiso ze-HG/20613-2009 kanye ne-HG/T20634-2009 zezinamathiseli zemithambo yokucindezela zidinga ukwelashwa kwe-bluing.

2. I-phosphate phosphating inqubo yokusabela kwamakhemikhali kanye ne-electrochemical ukwakha ifilimu yokuguqulwa kwamakhemikhali e-phosphate, kanti ifilimu yokuguqulwa kwe-phosphate eyakhiwe ibizwa ngokuthi ifilimu yokuguqulwa kwe-phosphate. Inhloso eyinhloko ye-phosphate ukuhlinzeka ngesivikelo sensimbi eyisisekelo nokuvimbela insimbi ukuthi ingagqwali ngezinga elithile, ukuthuthukisa ukunamathela kanye nekhono lokulwa nokugqwala kwengqimba yefilimu yopende ngaphambi kokupenda, kanye nokunciphisa ukungqubuzana kanye nokugcoba enkambisweni yokusebenza ebandayo yensimbi. Izikhonkwane ezinkulu ezinezinhlangothi ezimbili zemithambo yokucindezela ziyadingeka ukuze zigqwaliswe nge-phosphate.

3. I-hot-dip galvanizing iwukucwilisa izingxenye zensimbi eziphukile ku-zinc encibilikisiwe encibilikisiwe ekushiseni okuphezulu okungaba ngu-600 °C, ukuze ubuso bezingxenye zensimbi bunamathele kungqimba ye-zinc, futhi ubukhulu bengqimba ye-zinc akufanele bube ngaphansi kuka-65μm kumapuleti amancane angaphansi kuka-5mm, futhi kungabi ngaphansi kuka-86μm kumapuleti amakhulu angu-5mm nangaphezulu. Ukuze kudlale inhloso yokulwa nokugqwala.

4. I-Dacromet I-Dacromet iyisifinyezo se-DACROMET, esibizwa ngokuthi i-Dacromet, i-Dacromet, i-Dicron. Ibizwa ngokuthi i-zinc-chromium coating eShayina, iwuhlobo olusha lwe-anticorrosive coating ene-zinc powder, i-aluminium powder, i-chromic acid kanye namanzi acwebezelwe njengezingxenye eziyinhloko. Ayikho inkinga ye-hydrogen embrittlement futhi ukuhambisana kwe-torque-preload kuhle. Kungakhathaliseki ukuthi i-hexavalent chromium iyinkinga engokwemvelo, empeleni ifaneleka kakhulu kuma-fasteners anamandla aphezulu anezidingo eziphezulu zokuvikela ukugqwala.
