Kodi Zomwe Zimayambitsa Dzimbiri Pazikhombo Zodzikhomera Ndi Chiyani Ndi Momwe Mungakulitsire?

Zomwe zimatchedwa self-tapping screws ndi zomangira zomwe zimatha kudzigwedeza zokha, choncho ndizoyenera kumangirira mbali zopanda zitsulo kapena zitsulo zomwe sizifuna mabowo apansi ndi kugwedeza. Komabe, zomangira zoterezi zikachita dzimbiri, zidzakhudza kumangika kwake, chifukwa chake tiyenera kupeza chomwe chimayambitsa dzimbiri ndikupereka njira zowongolera.

Zomangira wamba nthawi zambiri zimakhala zathyathyathya-mutu, ndipo makulidwe amutu amakhala osasinthasintha, komazomangira zokhaamalozedwera, kuti athe kumaliza ntchito ya "self-tapping". Akhoza kudalira mawonekedwe awo a ulusi pazinthu zomwe zikuphatikizidwa. Thupi lophatikizidwa limagwiritsidwa ntchito kuti likwaniritse ulusi womwe umagwirizana nawo pogwiritsa ntchito "kugogoda, kubowola, kufinya ndi kukanikiza", kotero kuti thupi lophatikizidwa limakhazikika pamodzi.

Zifukwa za screw dzimbiri zimawunikidwa motere:

1. Nkhani za ndondomeko ya Electroplating. Pa electroplating, ngati zomangira siziuma panthawi yowumitsa, nthunzi yamadzi imakhalabe. Kapena zaumitsidwa, koma madzi a condensation amapangidwa panthawi yolongedza, zomwe zimapangitsa kuti pakhale mankhwala pakati pa madzi ndi zomangira, ndipo zomangira zimakhala dzimbiri. Kuonjezera apo, ngati plating ndi yosauka ndipo makulidwe a plating wosanjikiza siwoyenera, kukana kwa dzimbiri kwa zomangira kumakhala kofooka ndipo kumachita dzimbiri mosavuta.

2. Nkhani zosungirako kapena kugwiritsa ntchito chilengedwe. Panthawi yosungira kapena kugwiritsa ntchito, malo osasangalatsa a chilengedwe amachititsa kuti zomangira zichite dzimbiri. Mwachitsanzo, malo okhala ndi mchere wambiri, acidity, saltiness, kutentha kwambiri, ndi chinyezi chambiri amapangitsa dzimbiri ndi okosijeni wa zomangira, zomwe zimapangitsa dzimbiri.

Njira yowonjezera ili motere:

1. Electroplating ndondomeko. Pamene electroplating, yesani kusankha plating mtundu ndi yaitali mchere kutsitsi nthawi kuyesa. Kuchita electroplating mosamalitsa malinga ndi ndondomeko electroplating ndi kulamulira makulidwe a wosanjikiza electroplated. Pofuna kupititsa patsogolo mphamvu yolimbana ndi dzimbiri, utoto wotsutsa-dzimbiri ukhoza kupoperanso pamwamba pa zomangira.

2. Malo osungira. Ikani zomangirazo pamalo opumira mpweya, owuma kutali ndi dzuwa. Payenera kukhala mtunda wina pakati pa zomangira ndi pansi.

Chifukwa chomwe zomangira zomangira dzimbiri nthawi zambiri ndichifukwa choti njira yopangira ma electroplating ndiyosayenerera kapena malo osungira ndikugwiritsa ntchito si abwino. Chifukwa chake, ngati mukufuna kuti zomangira zisachite dzimbiri, muyenera kuyang'ana mbali ziwirizi.

Monga wopanga zida zodzipangira okha ku China,Aozhan Fastenerswakhala akudzipereka kupereka makasitomala ndi apamwamba, odalirika kudziona pogogoda wononga mankhwala mu zosiyanasiyana specifications ndi zitsanzo. Timatengera luso lazopangapanga zapamwamba komanso kuwongolera kokhazikika kuti tiwonetsetse kuti wononga chilichonse chodzipangira chokha chimatha kukwaniritsa zosowa zamakasitomala ndikuchita bwino kwambiri m'magawo osiyanasiyana ogwiritsira ntchito. Aozhan Fasteners apitiliza kugwira ntchito molimbika kuti apatse makasitomala zinthu zabwinoko komanso ntchito zambiri zamaluso, ndikukhala bwenzi lodalirika la makasitomala.
