Umhloli wokuqina usetshenziselwa ikakhulukazi ukuhlolwa kokuqina kwensimbi efojiwe kanye nensimbi eyinsimbi enesakhiwo esingalingani.Ukuqina kwensimbi efojiwe kanye nensimbi empunga kunokuxhumana okuhle nokuhlolwa okuqinile.Ingase futhi isetshenziselwe izinsimbi ezingezona ayoni kanye nensimbi emnene, futhi i-indenter yebhola yodayamitha encane ingakala usayizi omncane nezinto ezizacile.
Ukuqina kusho ikhono lempahla ukumelana nokuguquguquka kwendawo, ikakhulukazi ukuwohloka kwepulasitiki, ukuhlehla noma ukuklwebheka, futhi kungenye yezinkomba zokusebenza ezibalulekile zezinto zensimbi.Ngokuvamile, ukuphakama kokuqina, kungcono ukumelana nokugqoka.Kuyinkomba yokukala ukuthamba nobulukhuni bezinto.Ngokwezindlela ezihlukene zokuhlola, ubulukhuni buhlukaniswe ngezinhlobo ezintathu.Ake sibheke ngayinye yazo:
Ukuqina kokuklwebha:
Ngokuyinhloko isetshenziselwa ukuqhathanisa ukuthamba nobulukhuni bamaminerali ahlukene.Indlela yokukhetha induku enomkhawulo owodwa oqinile kanti enye ithambile, udlulise izinto okufanele zihlolwe eduze kwenduku, futhi unqume ubulukhuni bento okufanele ihlolwe ngokuya ngokuma kokuklwebheka.Uma sikhuluma ngokufaneleka, izinto eziqinile zenza imihuzuko emide kanti izinto ezithambile zenza imihuzuko emifushane.
Ukuqina kokucindezela:
Ikakhulukazi esetshenziselwa izinto zensimbi, indlela iwukusebenzisa umthwalo othile ukuze ucindezele i-indenter eshiwo entweni ezohlolwa, futhi uqhathanise ukuthamba nobulukhuni bezinto okufanele zihlolwe ngosayizi we-deformation yepulasitiki yendawo ebusweni bendawo. impahla.Ngenxa yomehluko we-indenter, ubude bomthwalo nomthwalo, kunezinhlobo eziningi zokuqina kokuhlehlisa, ikakhulukazi okuhlanganisa ukuqina kwe-Brinell, ukuqina kwe-Rockwell, ubulukhuni be-Vickers kanye nokuqina okuncane.
Ukuqina kokubopha kabusha:
Ikakhulukazi esetshenziselwa izinto zensimbi, indlela yokwenza isando esincane esikhethekile siwe ngokukhululekile ukusuka ekuphakameni okuthile ukuze sibe nomthelela kusampula yezinto ezizohlolwa, futhi sisebenzise inani lamandla obunzima agcinwe (bese ekhululwa) kusampula ngesikhathi sokuhlolwa. umthelela (ngokubuya kwesando esincane) isilinganiso sobude bokweqa) ukuze kunqunywe ubulukhuni bento.
Umhloli wobulukhuni okhiqizwe i-Shandong Shancai/Laizhou Laihua Testing Instrument wuhlobo lwethuluzi lokuhlola ubulukhuni be-indentation, elibonisa ikhono lempahla yokumelana nokungena kwezinto eziqinile endaweni yayo.Zingaki izinhlobo ezikhona?
1. I-Brinell Hardness Tester: Isetshenziselwa ikakhulukazi ukukala ubulukhuni bensimbi ekhonjiwe, insimbi, izinsimbi ezingenayo insimbi nama-alloys athambile.Kuyindlela yokuhlola ubulukhuni bokunemba okuphezulu.
2. Umhloli wokuqina we-Rockwell: umhloli wokuqina we-Rockwell ongahlola ubulukhuni bensimbi ngokuthinta isampula ohlangothini olulodwa.Ithembele kumandla kazibuthe ukuze ikhangise ikhanda lomhloli wokuqina we-Rockwell endaweni yensimbi, futhi ayidingi ukusekela isampula.
3. I-Vickers Hardness Tester: I-Vickers Hardness Tester iwumkhiqizo wobuchwepheshe obuphezulu ohlanganisa i-optoelectronics kanye ne-electronics.Umshini unomumo wenoveli, unokwethenjelwa okuhle, ukusebenza kahle nokunembile.Imishini yokuhlola ubulukhuni be-S ne-Knoop.
4. Umhloli wokuqina we-Brockwell: Umhloli wokuqina we-Brockwell ufanelekile ukunquma ubulukhuni bezinsimbi ezisansimbi, izinsimbi ezingenayo insimbi, ama-alloys aqinile, izendlalelo ze-carburized kanye nezendlalelo eziphathwe ngamakhemikhali.
5. Umhloli we-Microhardness: Umhloli we-Microhardness iyithuluzi elinembile lokuhlola izakhiwo zensimbi emishinini, i-metallurgy nezinye izimboni, futhi isetshenziswa kabanzi ezimbonini ezihlukahlukene.
6. I-Leeb Hardness Tester: Isimiso sayo esiyisisekelo siwukuthi umzimba onomthelela onesisindo esithile uthinta indawo engaphezulu yesampula ngaphansi kwamandla athile okuhlola, futhi ukala isivinini somthelela kanye nesivinini sokuphindaphindeka somzimba onomthelela ebangeni elingu-1 mm ukusuka endaweni. indawo yesampula, kusetshenziswa izimiso zozibuthe kagesi, i-voltage elingana nesivinini iyangeniswa.
7. I-Webster hardness tester: Isimiso se-Webster hardness tester iyi-indenter yensimbi eqinile enomumo othile, ecindezelwa ebusweni besampula ngaphansi kwamandla okuhlola entwasahlobo ajwayelekile.
8. I-Barcol Hardness Tester: Isihloli sokuqina sokuqina.Icindezela i-indenter ethile kusampula ngaphansi kwesenzo samandla avamile asentwasahlobo, futhi inquma ubulukhuni besampula ngokujula kokuhlehlisa.
