Kodi Grade 8.8 Bolts High-Temperature Resistant?
Gulu 8.8 mabawuti ndi mtundu wogwiritsidwa ntchito kwambiri wa zomangira zolimba kwambiri, zomwe zimatchuka kwambiri pakumanga, zamagalimoto, komanso uinjiniya wamba chifukwa cha mphamvu zawo zodalirika komanso kulimba.
Makhalidwe
1. Mapangidwe Azinthu: Kawirikawiri, ma bolts a Giredi 8.8 amapangidwa kuchokera kuzitsulo zotsika kwambiri kapena zitsulo zapakatikati za kaboni zomwe zimatenthedwa ndi kutentha (zozimitsidwa ndi kutenthedwa) kuti zikwaniritse zofunikira zamakina.
2. Katundu Wamakina:
- Mphamvu Yamphamvu: Gulu 8.8 mabawuti khalani ndi mphamvu zocheperako za 800 N/mm² (800 MPa).
- Mphamvu Zokolola: Mphamvu ya zokolola, yomwe ndi pamene bolt idzayamba kupunduka pulasitiki, ndi osachepera 640 N/mm² (640 MPa), yomwe ndi 80% ya mphamvu zolimba.
- Kutalikira: Kutalikirako kumakhala pafupifupi 15%, zomwe zikuwonetsa kuthekera kwazinthu kutambasuka musanasweke.
3. Kupanga Ulusi: Ma bolts awa amatsata machitidwe opangira ulusi, kuwonetsetsa kuti zikugwirizana ndi zomangira zina ndi zigawo zomwe zili mugulu lamphamvu lomwelo.
4. Pamwamba Pamwamba: Kutengera kugwiritsa ntchito, mabawuti a Giredi 8.8 amatha kubwera ndi zomaliza zosiyanasiyana, kuphatikiza zokutira zamagalasi, zokutira zinki, kapena mankhwala ena oletsa dzimbiri kuti apititse patsogolo kulimba kwawo m'malo ovuta.
Kodi Grade 8.8 Bolts High-Temperature Resistant?
Gulu 8.8 mabawuti kukhala ndi makina abwino pa kutentha kwabwino (nthawi zambiri pansi pa 100 ° C), koma ntchito yawo ingakhudzidwe pamene kutentha kumadutsa malire ena. Kawirikawiri, mabawuti a Giredi 8.8 amatha kukhalabe ndi mphamvu zambiri pafupifupi 150 ° C, koma mphamvu zawo zimatha kuchepetsedwa kwambiri kutentha kumakwera kwambiri. Kuonjezera apo, kugwiritsidwa ntchito kwa nthawi yaitali m'madera otentha kwambiri kungayambitse Creep, Oxidation kapena zochitika zina zowonongeka za zinthu, zomwe zimakhudza kudalirika ndi moyo wautumiki wa ma bolts. Ngati mabawuti akuyenera kugwiritsidwa ntchito m'malo otentha kwambiri, mabawuti okhala ndi mphamvu zapamwamba (monga 10.9 kapena 12.9) nthawi zambiri amasankhidwa, kapena zida zopangidwa mwapadera zothana ndi kutentha monga chitsulo chosagwira kutentha, chitsulo chosapanga dzimbiri kapena ma aloyi a faifi tambala amagwiritsidwa ntchito popanga mabawuti kuti atsimikizire kuti atha kukhalabe ndi mphamvu zokwanira komanso kukhazikika pakutentha kwambiri.
Mwachidule, mabawuti a giredi 8.8 amatha kupirira kutentha kwambiri, koma akamapitilira kutentha kwawo, tikulimbikitsidwa kusankha zida zoyenera komanso magiredi a bawuti.
ABUSA imayang'ana pakupanga zida zolondola monga Screws, Bolts, Nuts, Washers, Rivets, Thread rods, Misomali, Anchors ndi Zida, ndi zina zotero.
