Ibanga B kunye nebanga C ziibanga ezimbini ezahlukeneyo phantsi komgangatho we-ASTM A500.
I-ASTM A500ngumgangatho ophuhliswe yi-ASTM International wemibhobho yesakhiwo sentsimbi yekhabhoni edityanisiweyo nengenamthungo.
Okulandelayo, masizithelekise size sizithelekise ngeendlela ezahlukeneyo ukuze siqonde ukuba zifana kwaye zahluke kangakanani.
Umahluko
I-ASTM A500 Grade B kunye ne-C zahluke kakhulu kwimilo yeekhemikhali, iipropati zokuxinana, kunye neendawo zokusetyenziswa.
Umahluko kwiComposition yeKhemikhali
Kwimigangatho ye-ASTM A500, kukho iindlela ezimbini zokuhlalutya ukwakheka kweekhemikhali zentsimbi: uhlalutyo lobushushu kunye nohlalutyo lwemveliso.
Uhlalutyo lobushushu lwenziwa ngexesha lenkqubo yokunyibilikisa intsimbi. Injongo yalo kukuqinisekisa ukuba ukwakheka kweekhemikhali zentsimbi kuyahlangabezana neemfuno zomgangatho othile.
Uhlalutyo lwemveliso, kwelinye icala, lwenziwa emva kokuba intsimbi sele yenziwe imveliso. Le ndlela yohlalutyo isetyenziselwa ukuqinisekisa ukuba ulwakhiwo lweekhemikhali lwemveliso yokugqibela luyahlangabezana neemfuno ezichaziweyo.
Akumangalisi ukuba umxholo wekhabhoni kwiBanga C uphantsi kancinci kunoweBanga B, nto leyo ethetha ukuba iBanga C linokuqina okungcono xa kudityaniswa naxa kusenziwa i-molding.
Umahluko kwiipropati zokuThatha
Ibanga BNgokuqhelekileyo inezinga eliphezulu lokuguquguquka, nto leyo evumela ukuba inwebeke xa ixinene ngaphandle kokuqhekeka, kwaye ifanelekile kwizakhiwo ezifuna ukugoba okanye ukuguqulwa okuthile.
Ibanga C: Inamandla aphezulu okutsalwa kunye nokukhupha isivuno ngenxa yokwakheka kwayo ngamakhemikhali, kodwa isenokuba ne-ductile encinci kuneGrade B.
Umahluko kwiSicelo
Nangona zombini zisetyenziswa kwizicelo zesakhiwo nezenkxaso, ugxininiso lwahlukile.
Ibanga BNgenxa yeempawu zayo zokuwelda nokwakha ezingcono, isetyenziswa rhoqo kwizakhiwo zokwakha, ukwakhiwa kweebhulorho, ukuxhasa izakhiwo, njl.njl., ingakumbi xa izakhiwo kufuneka ziweldwe kwaye zigotywe.
Ibanga C: Ngenxa yokuba inamandla aphezulu, isetyenziswa rhoqo kwizicelo ezithwalwa yimithwalo ephezulu, njengokwakhiwa kwemizi-mveliso, izakhiwo zenkxaso yoomatshini abanzima, njalo njalo.
Ukufana
Nangona iBanga B neBanga C zahlukile ngeendlela ezahlukeneyo, zikwafana ngeempawu ezifanayo.
Imilo efanayo yeCandelo eliQhelekileyo
Iimilo zecandelo elingenanto zingqukuva, zisikwere, zixande, kwaye zimile okweqanda.
Unyango lobushushu
Zonke zivumela intsimbi ukuba ikhululeke kuxinzelelo okanye ivalwe.
Iinkqubo zovavanyo ezifanayo
Zombini iiBanga B kunye ne-C kufuneka zihlangabezane neemfuno ze-ASTM A500 zohlalutyo lobushushu, uhlalutyo lwemveliso, uvavanyo lokuxinana, uvavanyo lokuthamba, uvavanyo lokutshaya, kunye novavanyo lokuqhekeza iWedge.
Unyamezelo Olufanayo
Umzekelo wecandelo elingqukuva elingenanto.
Iimveliso zethu eziNxulumeneyo
Xa ukhetha ukuba uza kusebenzisa na iityhubhu ze-ASTM A500 Grade B okanye Grade C, kufuneka kuqwalaselwe iimfuno zobunjineli kunye nokusebenza kakuhle kweendleko.
Umzekelo, kwizakhiwo ezingadingi amandla aphezulu kodwa ezomeleleyo, iBanga B lisenokuba lolona khetho lungabizi kakhulu. Kwiprojekthi ezifuna amandla angakumbi kunye nomthamo wokuthwala umthwalo, iBanga C libonelela ngokusebenza okufunekayo, nangona kubiza kakhulu.
Iithegi: astm a500, ibanga b, ibanga c, ibanga b vs c.
