Imibuzo Evame Ukubuzwa (FAQ)

Uyini umehluko phakathi kwamabhawodi eBanga 8.8 kanye neBanga 10.9?

Amabhawodi eBanga le-10.9 anokuqina okuphezulu futhi akhiqiza amandla kunamabhawodi eBanga lesi-8.8. Ikakhulukazi, iBanga le-10.9 linamandla okudonsa amancane angu-1040 MPa futhi likhiqiza amandla angu-940 MPa, kanti iBanga lesi-8.8 linama-MPa angama-800 kanye nama-MPa angu-640 akhiqiza amandla. Ibanga le-10.9 lisetshenziselwa izicelo ezibucayi kakhulu, ezinomthwalo omkhulu.

Ingabe amabhawodi anamandla aphezulu angasetshenziswa kabusha?

Ngokuvamile, amabhawodi esakhiwo anamandla aphezulu (afana ne-ASTM A325/A490 noma i-ISO 10.9) awanconywa ukuthi aphinde asetshenziswe ngemva kokuqiniswa ukuze alayishe ngokugcwele. Ukwelula nokuguqulwa kwentambo kungalimaza ubuqotho babo. Kuzinhlelo zokusebenza ezingabalulekile, uma ibhawudi lingabonisi zimpawu zokunwebeka noma ukulimala kwentambo, ingasetshenziswa futhi ngokuqapha, kodwa ukumiselela kuwumkhuba ongcono kakhulu wamajoyinti abalulekile ngokuphepha.

Ngiyivikela kanjani i-galvanic corrosion ngamabhawudi anamandla aphezulu?

Ukugqwala kwe-galvanic kwenzeka lapho izinsimbi ezingafani zithintana lapho kukhona i-electrolyte. Ukuze uvimbele lokhu, sebenzisa ama-bolts enziwe ngezinto eziseduze nesisekelo sensimbi ochungechungeni lwe-galvanic, noma sebenzisa ama-washers avikelayo nemikhono. Izembatho ezifana ne-Dacromet noma i-hot-dip galvanizing nazo zinikeza umgoqo. Gwema ukusebenzisa amabhawodi e-aluminium anezakhiwo zensimbi ngaphandle kokuhlukaniswa okufanele.

Ithini impilo yeshelufu yamabhawodi anamandla aphezulu?

Amabhawodi anamandla aphezulu awanayo idethi emisiwe yokuphelelwa yisikhathi, kodwa asengozini yokugqwala kanye nokugqwala kwe-hydrogen ngokuhamba kwesikhathi uma egcinwe ngendlela engafanele. Zigcine endaweni eyomile, yasendlini kude namakhemikhali. Uma amabhawodi egcinwe isikhathi esingaphezu kwezinyanga eziyisi-6, ikakhulukazi uma emboziwe, wahlolele ukugqwala noma ukuwohloka koqweqwe lwawo ngaphambi kokusetshenziswa. Ukuhlolwa kabusha kungase kudingeke ezinhlelweni ezibucayi.

Ingabe uhlinzeka ngamabhawodi wamandla aphezulu we-OEM?

Yebo, sinikezela ngezinsizakalo ze-OEM zobukhulu bangokwezifiso, izitayela zekhanda, namabanga wezinto ezibonakalayo. Ithimba lethu lonjiniyela lingasebenza ngemidwebo noma amasampula ukuze likhiqize izibophelelo ze-bespoke ezihlangabezana nezidingo ezithile zephrojekthi, inqobo nje uma lithobela izithiyo zokukhiqiza ezingenzeka kanye nezimiso zensimbi.
