Isihloli sobulukhuni sisetshenziswa kakhulu ekuhlolweni kobulukhuni bensimbi ehlanganisiwe kanye nensimbi ehlanganisiwe enesakhiwo esingalingani. Ubulukhuni bensimbi ehlanganisiwe kanye nensimbi ehlanganisiwe empunga buhambisana kahle nokuhlolwa kokuthamba. Bungasetshenziswa futhi ezinsimbini ezingezona insimbi kanye nensimbi ethambile, kanti i-indenter encane yebhola enobubanzi ingalinganisa usayizi omncane kanye nezinto ezincane.
Ukuqina kubhekisela ekhonweni lento yokumelana nokuguquguquka kwendawo, ikakhulukazi ukuguquguquka kwepulasitiki, ukugoba noma ukuklwebheka, futhi kungenye yezinkomba ezibalulekile zokusebenza kwezinto zensimbi. Ngokuvamile, lapho ubunzima buphakeme, kulapho ukumelana nokuguguleka kuba ngcono khona. Kuyinkomba yokukala ubumnene nokuqina kwezinto. Ngokwezindlela ezahlukene zokuhlola, ubulukhuni buhlukaniswe ngezinhlobo ezintathu. Ake sibheke ngayinye yazo:
Ukuqina kokuklwebheka:
Isetshenziswa kakhulu ukuqhathanisa ubumnene nokuqina kwamaminerali ahlukene. Indlela iwukukhetha induku enokuphela okuqinile kanti okunye ukuphela kuthambile, ukudlulisa izinto ezizohlolwa eceleni kwenduku, bese kunqunywa ubulukhuni bezinto ezizohlolwa ngokuya ngendawo yokuklwebheka. Ngokwezinga, izinto eziqinile zenza imiklwebhe emide kanti izinto ezithambile zenza imiklwebhe emifushane.
Ukuqina kokucindezela:
Isetshenziswa kakhulu ezintweni zensimbi, indlela iwukusebenzisa umthwalo othile ukucindezela i-indenter ecacisiwe ezintweni ezizohlolwa, bese uqhathanisa ubumnene nobunzima bezinto ezizohlolwa ngobukhulu bokuguqulwa kwepulasitiki yendawo ebusweni bezinto. Ngenxa yomehluko we-indenter, umthwalo kanye nobude bomthwalo, kunezinhlobo eziningi zobulukhuni be-indenter, ikakhulukazi okuhlanganisa ubulukhuni bukaBrinell, ubulukhuni bukaRockwell, ubulukhuni bukaVickers kanye nobulukhuni obuncane.
Ubulukhuni bokubuyela emuva:
Isetshenziswa kakhulu ezintweni zensimbi, indlela iwukwenza isando esincane esikhethekile siwe ngokukhululeka sisuka ekuphakameni okuthile ukuze sithinte isampula yezinto ezizohlolwa, bese sisebenzisa inani lamandla okucindezeleka agcinwe (bese ekhishwa) kusampula ngesikhathi sokushaya (ngokubuya kwesando esincane) ukulinganisa ukuphakama kokugxuma) ukuze kutholakale ubulukhuni bezinto.
Isihloli sobulukhuni esikhiqizwe yiShandong Shancai/Laizhou Laihua Testing Instrument uhlobo lwethuluzi lokuhlola ubulukhuni lokugoba, olukhombisa ikhono lento yokumelana nokungena kwezinto eziqinile ebusweni bayo. Zingaki izinhlobo ezikhona?
1. Isivivinyo Sokuqina Kwe-Brinell: Sisetshenziswa kakhulu ukukala ubulukhuni bensimbi ephothiwe, insimbi, izinsimbi ezingezona i-ferrous kanye nama-alloy athambile. Kuyindlela yokuhlola ubulukhuni enembile kakhulu.
2. Umhloli wobulukhuni beRockwell: umhloli wobulukhuni beRockwell ongahlola ubulukhuni bensimbi ngokuthinta isampula ohlangothini olulodwa. Ithembele emandleni kazibuthe ukuze imunce ikhanda lomhloli wobulukhuni beRockwell ebusweni bensimbi, futhi ayidingi ukusekela isampula
3. Isivivinyo Sokuqina Kwe-Vickers: Isivivinyo Sokuqina Kwe-Vickers siwumkhiqizo wobuchwepheshe obuphezulu ohlanganisa i-optoelectronics kanye ne-electronics. Lo mshini unesimo esisha, unokwethenjelwa okuhle, ukusebenza kahle kanye nokuzwela. Imishini yokuhlola ukuqina kwe-S kanye ne-Knoop.
4. Umhloli wobulukhuni beBrockwell: Umhloli wobulukhuni beBrockwell ufanelekela ukunquma ubulukhuni bezinsimbi zensimbi, izinsimbi ezingezona insimbi, ama-alloy aqinile, izendlalelo ezifakwe i-carburized kanye nezendlalelo eziphathwe ngamakhemikhali.
5. Umhloli wokuqina kwe-Micro: Umhloli wokuqina kwe-Micro uyithuluzi lokunemba lokuhlola izakhiwo zezinto zensimbi emishinini, ezimbonini zensimbi nakwezinye izimboni, futhi lisetshenziswa kabanzi ezimbonini ezahlukahlukene.
6. Isivivinyo Sokuqina Kwe-Leeb: Isimiso sayo esiyisisekelo ukuthi umzimba othintekayo onobunzima obuthile uthinta ubuso besampula ngaphansi kwamandla athile okuhlola, futhi ulinganisa ijubane lomthelela kanye nejubane lokubuyela emuva komzimba othintekayo ebangeni elingu-1 mm ukusuka ebusweni besampula, kusetshenziswa izimiso ze-electromagnetic, kukhiqizwa i-voltage ehambisana nesivinini.
7. Umhloli wobulukhuni beWebster: Umgomo womhloli wobulukhuni beWebster uyi-indenter yensimbi eqinile enesimo esithile, ecindezelwa ebusweni besampula ngaphansi kwamandla okuhlola entwasahlobo ajwayelekile.
8. Isivivinyo Sokuqina Kwe-Barcol: Siyisivivinyo sokuqina kwe-indentation. Sicindezela i-indent ethile kusampula ngaphansi kwesenzo samandla esiphethu ajwayelekile, futhi sinquma ubunzima besampula ngokujula kwe-indentation.
Isikhathi sokuthunyelwe: Meyi-24-2023
