Isivavanyeli sobulukhuni sisetyenziselwa kakhulu uvavanyo lobulukhuni bentsimbi eqingqiweyo kunye nesinyithi esityhidiweyo esinesakhiwo esingalinganiyo. Ubulukhuni bentsimbi eqingqiweyo kunye nesinyithi esingwevu buhambelana kakuhle novavanyo lokuxinana. Ingasetyenziselwa neentsimbi ezingezizo i-ferrous kunye nesinyithi esithambileyo, kwaye i-indenter yebhola encinci inokulinganisa ubungakanani obuncinci kunye nezinto ezincinci.
Ukuqina kubhekisa kubuchule bezinto zokumelana nokuguquguquka kwendawo, ngakumbi ukuguquguquka kweplastiki, ukuxinana okanye imikrwelo, kwaye yenye yezona zibonakaliso zibalulekileyo zokusebenza kwezinto zesinyithi. Ngokubanzi, xa ubunzima buphezulu, kokukhona ukumelana nokuguguleka kungcono. Sisikhombisi sokulinganisa ukuthamba kunye nokuqina kwezinto. Ngokweendlela ezahlukeneyo zovavanyo, ubunzima bahlulwe baba ziintlobo ezintathu. Makhe sijonge nganye kuzo:
Ubunzima bokukrwela:
Isetyenziswa kakhulu ukuthelekisa ubuthambile kunye nobunzima beeminerali ezahlukeneyo. Le ndlela kukukhetha intonga enesiphelo esinye esiqinileyo nesinye esithambileyo, ukudlulisa izinto eziza kuvavanywa ecaleni kwentonga, kunye nokuchonga ubulukhuni bezinto eziza kuvavanywa ngokwendawo yokukrwela. Ngokwemigangatho, izinto eziqinileyo zenza imikrwelo emide kwaye izinto ezithambileyo zenza imikrwelo emifutshane.
Ubunzima bokufaka i-press-in:
Eyona ndlela isetyenziswa kakhulu kwizinto zesinyithi, kukusebenzisa umthwalo othile ukucinezela i-indenter echaziweyo kwizinto eziza kuvavanywa, kwaye uthelekise ukuthamba kunye nobunzima bezinto eziza kuvavanywa ngobukhulu bokuguqulwa kweplastiki yendawo kumphezulu wezinto. Ngenxa yomahluko phakathi kwe-indenter, umthwalo kunye nobude bomthwalo, kukho iintlobo ezininzi zobunzima bokugoba, ikakhulu kubandakanya ubunzima bukaBrinell, ubunzima bukaRockwell, ubunzima bukaVickers kunye nobunzima obuncinci.
Ukuqina kokubuyela umva:
Isetyenziswa kakhulu kwizixhobo zesinyithi, le ndlela kukwenza isando esincinci esikhethekileyo siwe ngokukhululekileyo ukusuka kubude obuthile ukuze sichaphazele isampuli yezinto eziza kuvavanywa, kwaye sisebenzise ubungakanani bamandla oxinzelelo agciniweyo (aze akhutshwe) kwisampuli ngexesha lokubetha (ngokubuya kwesando esincinci) ukulinganisa ukuphakama kokutsiba) ukufumanisa ubunzima bezinto.
Isivavanyeli sobulukhuni esenziwe yiShandong Shancai/Laizhou Laihua Testing Instrument luhlobo lwesixhobo sokuvavanya ubulukhuni esifakwa ngaphakathi, nto leyo ebonisa amandla ezinto ezisetyenziswayo okumelana nokungena kwezinto ezilukhuni kumphezulu wazo. Zingaphi iintlobo ezikhoyo?
1. I-Brinell Hardness Tester: Isetyenziswa kakhulu ukulinganisa ubulukhuni bentsimbi ephosiweyo, intsimbi, iintsimbi ezingezizo iintsimbi kunye nee-alloys ezithambileyo. Yindlela yokuvavanya ubulukhuni echanekileyo.
2. Umvavanyi wobulukhuni beRockwell: umvavanyi wobulukhuni beRockwell onokuvavanya ubulukhuni besinyithi ngokuchukumisa isampuli kwelinye icala. Uxhomekeke kumandla emagnethi ukufunxa intloko yomvavanyi wobulukhuni beRockwell kumphezulu wentsimbi, kwaye akufuneki uxhase isampuli.
3. IsiVavanyi soBulukhuni beVickers: IsiVavanyi soBulukhuni beVickers yimveliso yobuchwepheshe obuphezulu edibanisa i-optoelectronics kunye ne-elektroniki. Lo matshini unesimo esitsha, uthembekile, usebenza kakuhle kwaye uyaqondakala. Izixhobo zokuvavanya ubulukhuni beS kunye neKnoop.
4. Umvavanyi wobulukhuni beBrockwell: Umvavanyi wobulukhuni beBrockwell ufanelekile ukumisela ubulukhuni beentsimbi zentsimbi, iintsimbi ezingezizo iintsimbi, ii-alloys eziqinileyo, iileya ezine-carburised kunye neeleya eziphathwe ngeekhemikhali.
5. Isivavanyeli sobunzima be-Microhardness: Isivavanyeli sobunzima be-Microhardness sisixhobo esichanekileyo sokuvavanya iimpawu zezinto zesinyithi koomatshini, kwi-metallurgy nakwamanye amashishini, kwaye sisetyenziswa kakhulu kumashishini ahlukeneyo.
6. I-Leeb Hardness Tester: Umgaqo wayo osisiseko kukuba umzimba ochaphazelekayo onobunzima obuthile uchaphazela umphezulu wesampuli phantsi kwamandla athile ovavanyo, kwaye ulinganisa isantya soxinzelelo kunye nesantya sokubuyela umva komzimba ochaphazelekayo kumgama we-1 mm ukusuka kumphezulu wesampuli, kusetyenziswa imigaqo ye-electromagnetic, i-voltage ehambelana nesantya iyabangelwa.
7. Umvavanyi wobulukhuni beWebster: Umgaqo womvavanyi wobulukhuni beWebster sisithinteli sentsimbi eqinileyo esinomfanekiso othile, esicinezelwa kumphezulu wesampuli phantsi kwamandla ovavanyo lwentwasahlobo aqhelekileyo.
8. I-Barcol Hardness Tester: Sisivavanyeli sokuqina kwe-indentation. Sicinezela i-indent ethile kwisampulu phantsi kwesenzo samandla entwasahlobo aqhelekileyo, kwaye simisela ubunzima besampulu ngobunzulu be-indentation.
