Zinthu Zamalonda
(1) Zinthu ndi Mphamvu
Chitsulo Chapamwamba: Chopangidwa ndi chitsulo chapamwamba kwambiri monga 42CrMoA, kuonetsetsa kuti bolt ili ndi mphamvu zambiri komanso kulimba bwino kuti ipirire kugwedezeka kwakukulu komanso kugwedezeka kwa ma excavator ndi ma bulldozer pa ntchito yovuta.
Mphamvu Yaikulu: Mphamvu yofanana ikuphatikizapo 8.8, 10.9, ndi 12.9. Maboluti a kalasi 10.9 ali ndi mphamvu yokoka ya 1000-1250MPa ndi mphamvu yokoka ya 900MPa, zomwe zimakwaniritsa zofunikira pakugwiritsa ntchito makina ambiri omanga; Maboluti a kalasi 12.9 ali ndi mphamvu yokoka ya 1200-1400MPa ndi mphamvu yokoka ya 1100MPa, yoyenera magawo apadera omwe ali ndi mphamvu yayikulu kwambiri.
(2) Kapangidwe ndi Kapangidwe
Kapangidwe ka Mutu: Kawirikawiri kapangidwe ka mutu wa hexagonal, komwe kumapereka mphamvu yayikulu yolimbitsa kuti bolt ikhale yolimba ikagwiritsidwa ntchito ndipo sikophweka kumasula. Nthawi yomweyo, kapangidwe ka mutu wa hexagonal kamakhalanso kosavuta kuyika ndi kusokoneza ndi zida wamba monga ma wrench.
Kapangidwe ka Ulusi: Ulusi wolondola kwambiri, nthawi zambiri umagwiritsa ntchito ulusi wokhuthala, umakhala ndi magwiridwe antchito abwino odzitsekera wokha. Ulusiwo umakonzedwa bwino kuti ukhale wolondola komanso wolondola, zomwe zimapangitsa kuti bolt ikhale yolimba komanso yodalirika.
Kapangidwe Koteteza: Maboluti ena ali ndi chivundikiro choteteza pamutu. Mbali yakumtunda ya chivundikiro choteteza ndi malo opindika, omwe amatha kuchepetsa kukangana pakati pa boluti ndi nthaka panthawi yogwira ntchito, kuchepetsa kukana, ndikuwonjezera magwiridwe antchito a ma excavator ndi ma bulldozer.
(3) Chithandizo cha pamwamba
Chithandizo cha Galvanizing: Kuti botolo lisamavutike ndi dzimbiri, nthawi zambiri limapangidwa ndi galvanized. Chogwirira cha galvanized chimatha kuteteza dzimbiri ndi dzimbiri la botolo m'malo ozizira komanso owononga, zomwe zimapangitsa kuti botolo likhale ndi moyo wautali.
Chithandizo cha Phosphating: Maboluti ena amapangidwanso ndi phosphate. Phosphating layer imatha kuonjezera kuuma ndi kukana kuwonongeka kwa pamwamba pa boluti, komanso kumawonjezera kukana dzimbiri kwa boluti.
