②Iintlobo zezinto ezisebenzayo: Zisebenza kwizixhobo zesinyithi ezinobunzima obuphakathi, ezifana nee-alloys zobhedu, ii-alloys ze-aluminium, kunye nentsimbi enobunzima obuphakathi. ③ Iimeko eziqhelekileyo zokusetyenziswa: Ulawulo lomgangatho wezixhobo zesinyithi ezinobunzima obuphakathi. Uphando nophuhliso lwezinto kunye novavanyo lwelebhu. Uvavanyo lobunzima bezinto ngexesha lokwenziwa kunye nokucutshungulwa. ④ Iimpawu kunye neenzuzo: Umthwalo ophakathi: Zisebenza kwizixhobo ezinobunzima obuphakathi kwaye zinokulinganisa ngokuchanekileyo ubunzima bazo. Ukusetyenziswa okuguquguqukayo: Zisebenza kwiintlobo ngeentlobo zezinto ezinobunzima obuphakathi ezinokuguquguquka okunamandla. Ukuphindaphinda okuphezulu: Zibonelela ngeziphumo zokulinganisa ezizinzileyo nezihambelanayo.
⑥Amanqaku okanye imida: Ukulungiswa kwesampulu: Umphezulu wesampulu kufuneka ube tyaba kwaye ucoceke ukuqinisekisa ukuchaneka kweziphumo zokulinganisa. Imida yezinto: Kwizinto ezithambileyo kakhulu okanye eziqinileyo kakhulu, ezinye iindlela ezifanelekileyo zokuvavanya ubulukhuni zinokufuneka zikhethwe. Ukugcinwa kwezixhobo: Izixhobo kufuneka zilinganiswe kwaye zigcinwe rhoqo ukuqinisekisa ukuchaneka nokuthembeka komlinganiselo.
(3)HB2.5/187.5
① Indlela yokuvavanya kunye nomgaqo: Sebenzisa ibhola yentsimbi enobubanzi obuyi-2.5 mm ukuze ucinezele kumphezulu wezinto phantsi komthwalo oyi-187.5 kg, kwaye ulinganise ububanzi bokutsalwa ukuze ubale ixabiso lobunzima.
②Iintlobo zezinto ezisebenzayo: Zisebenza kwizinto zesinyithi ezithambileyo kunye nezinye ii-alloys ezithambileyo, ezifana ne-aluminium, i-alloy ye-lead, kunye nentsimbi ethambileyo.
③Iimeko eziqhelekileyo zokusetyenziswa: Ulawulo lomgangatho wezinto zesinyithi ezithambileyo. Uvavanyo lwezinto kwimizi-mveliso ye-elektroniki kunye nombane. Uvavanyo lokuqina kwezinto ezithambileyo ngexesha lokwenziwa nokucutshungulwa.
④Iimpawu kunye neenzuzo: Umthwalo ophantsi: Isebenza kwizinto ezithambileyo ukuze kuthintelwe ukuxinana kakhulu. Ukuphinda-phinda okuphezulu: Ibonelela ngeziphumo zokulinganisa ezizinzileyo nezihambelanayo. Uluhlu olubanzi lwezicelo: Iyakwazi ukuvavanya iintlobo ngeentlobo zezinto zesinyithi ezithambileyo.
