Ngaba iiBolts zeBanga lesi-8.8 ziyaxhathisa?
IBakala 8.8 iibholiti luhlobo olusetyenziswa ngokubanzi lwe-fastener ephezulu, ngakumbi ethandwa kulwakhiwo, iimoto, kunye nezicelo zobunjineli ngokubanzi ngenxa yamandla azo athembekileyo kunye nokuqina.
Iimpawu
1. Ukubunjwa kwezinto: Ngokuqhelekileyo, iibhotshi zeBanga le-8.8 zenziwe kwiintsimbi ze-alloy ephantsi okanye i-carbon steels ephakathi eziye zaphathwa ukushisa (zicinywe kwaye zifudumala) ukufezekisa izinto ezifunwayo zemishini.
2. IiPropati zoomatshini:
- Amandla Okuqina: IBakala 8.8 iibholiti ube namandla okuqina ama-800 N/mm² (800 MPa).
- Amandla eSivuno: Amandla esivuno, apho ibholithi iya kuqalisa ukonakala ngokweplastiki, ubuncinane yi-640 N/mm² (640 MPa), eyi-80% yamandla okuqina.
- Ubude: Ipesenteji yobude iqhelekile malunga ne-15%, ebonisa isakhono semathiriyeli ukolula phambi kokwaphuka.
3. Uyilo lwemisonto: Ezi bholithi zilandela iindlela zokuyila intambo eqhelekileyo, ziqinisekisa ukuhambelana nezinye izibophelelo kunye namacandelo kwiklasi yamandla efanayo.
4. Umphezulu wokuGqibela: Ngokuxhomekeke kwisicelo, iibholiti zeBanga lesi-8.8 zinokuza neentlobo ezahlukeneyo zokugqitywa komphezulu, kubandakanywa neengubo ezenziwe ngegalvanized, i-zinc plating, okanye ezinye iindlela zonyango ezichasene nokuhlwa ukunyusa ukuqina kwazo kwiimeko ezinzima.
Ngaba iiBolts zeBanga lesi-8.8 ziyaxhathisa?
IBakala 8.8 iibholiti baneempawu ezintle zomatshini kumaqondo obushushu okusetyenziswa ngokuqhelekileyo (ngokubanzi ngaphantsi kwe-100 ° C), kodwa ukusebenza kwabo kunokuchaphazeleka xa ubushushu budlula umda othile. Ngokuqhelekileyo, iibholithi zeBanga lesi-8.8 zisengawagcina amandla azo amaninzi malunga ne-150°C, kodwa amandla azo anokuncipha kakhulu xa ubushushu bunyuka ngakumbi. Ukongezelela, ukusetyenziswa kwexesha elide kwiindawo eziphezulu zokushisa kunokubangela i-Creep, i-Oxidation okanye enye i-degradation phenomena yezinto eziphathekayo, ezichaphazela ukuthembeka kunye nobomi benkonzo yeebholiti. Ukuba iibholiti kufuneka zisetyenziswe kwiindawo eziphakamileyo zokushisa, iibholiti ezinamabanga anamandla aphezulu (ezifana ne-10.9 okanye i-12.9) zivame ukukhethwa, okanye zenziwe ngokukodwa izixhobo ezichasene nobushushu obuphezulu njengensimbi enganyangekiyo, insimbi engenasici okanye i-nickel-based alloys isetyenziselwa ukuvelisa iibholiti ukuqinisekisa ukuba zisenako ukugcina amandla aneleyo kunye nokuzinza kumaqondo okushisa aphezulu.
Ngamafutshane, iibholiti ze-8.8 zinamandla athile okumelana namaqondo okushisa aphezulu, kodwa xa zidlula ukushisa kwazo, kuyacetyiswa ukuba ukhethe izinto ezifanelekileyo kunye namabakala e-bolt.
UMFUNDISI igxile kwimveliso ye-hardware echanekileyo efana ne-Screws, i-Bolts, i-Nuts, i-Washers, i-Rivets, i-Thread rods, izikhonkwane, i-Anchors kunye neZixhobo, njl.
