Umhloli wokuqina ithuluzi lokulinganisa ubulukhuni bezinto. Ngokuya ngezinto ezihlukene ezilinganiswayo, umhloli wokuqina ungasetshenziswa ezinkambu ezahlukene. Abanye abahloli bokuqina basetshenziswa embonini yokucubungula imishini, futhi bakala kakhulu ubulukhuni bezinto zensimbi. Okufana nokuthi: Umhloli wokuqina we-Brinell, umhloli wokuqina we-Rockwell, umhloli wokuqina ka-Leeb, umhloli wokuqina we-Vickers, umhloli we-microhardness, Umhloli wokuqina ogwini, umhloli wokuqina we-Webster njll. Izikophu zohlelo ezithize zalaba bahloli bokuqina zimi kanje:
Umhloli wokuqina we-Brinell:ikakhulukazi esetshenziselwa ukuhlola ubulukhuni bensimbi ekhandiwe nensimbi ekhonjiwe enesakhiwo esingalingani. Ukuqina kwe-Brinell yensimbi efojiwe kanye nensimbi empunga inokuxhumana okuhle nokuhlolwa kwe-tensile. Ukuhlolwa kokuqina kwe-Brinell kungaphinda kusetshenziselwe izinsimbi ezingezona ayoni kanye nensimbi ethambile. I-indenter yebhola elingudayamitha encane ingakala usayizi omncane nezinto ezizacile, futhi ikale izindawo zokulungisa ukushisa kanye neminyango yokuhlola ifekthri yezimboni zemishini ehlukahlukene. I-Brinell tester hardness isetshenziswa kakhulu ekuhloleni izinto ezingavuthiwe kanye nemikhiqizo eseqediwe kancane. Ngenxa yokuhlehlisa okukhulu, ngokuvamile akusetshenziselwa ukuhlolwa komkhiqizo oqediwe.
Umhloli wokuqina we-Rockwell:Hlola izinsimbi ezihlukahlukene ezingayoni nezingezona insimbi, hlola ubulukhuni bensimbi ecishiwe, insimbi ecishiwe nethambile, insimbi exutshwe nensimbi, ikesi eliqinile, amapuleti anobukhulu obuhlukahlukene, izinto ze-carbide, izinto zokusansimbi eziyimpuphu, izimbozo ezishisayo, ukubunjwa okubandayo, ukubunjwa okubambekayo. , ama-alloys e-aluminium, insimbi enensimbi, amapuleti ensimbi aqinile, njll.
I-Superficial Rockwell Hardness Tester:Isetshenziselwa ukuhlola ubulukhuni beshidi lensimbi elincanyana, ipayipi elincane lodonga, ikesi eliqinile nezingxenye ezincane, i-alloy eqinile, i-carbide, ikesi lensimbi eqinile, ishidi eliqinile, insimbi eqinile, insimbi ecishiwe nepholile, insimbi ephonsiwe, insimbi ekhonjiwe, i-aluminium, ithusi, i-magnesium nezinye izinsimbi ze-alloy.
Umhloli wobulukhuni be-Vickers : kala izingxenye ezincane, amapuleti ensimbi azacile, amafoil ensimbi, amashidi e-IC, izintambo, izendlalelo eziqinile eziqinile, izendlalelo ezifakwe ugesi, ingilazi, ubucwebe namaceramics, izinsimbi ezisansimbi, izinsimbi ezingenayo ayoni, amashidi e-IC, okokumbozwa kwendawo, izinsimbi ezilayiniwe; ingilazi, izitsha zobumba, i-agate, amatshe ayigugu, njll.; ukujula kanye nokuhlolwa kokuqina kwegradient kwezingqimba ze-carbonized kanye nokucisha izendlalelo eziqinile. Ukucutshungulwa kwezingxenyekazi zekhompyutha, imboni yezogesi, izesekeli zesikhunta, imboni yokubuka.
Knoopumhloli wokuqina:esetshenziswa kabanzi ukukala ubulukhuni bemifanekiso emincane nencane, okokumbozwa kwendawo okungaphezulu nezinye izibonelo, kanye nokukala ubulukhuni be-Knoop bezinto eziphukayo neziqinile njengengilazi, izitsha zobumba, i-agate, amatshe ayigugu okwenziwa, njll., ububanzi obusebenzayo: ukwelashwa kokushisa, i-carburization, ungqimba oluqinile olucishayo, ukumbozwa kwendawo, insimbi, izinsimbi ezingenayo insimbi nezingxenye ezincane nezincane, njll.
Umhloli wokuqina ka-Leeb:insimbi nensimbi ecijile, insimbi yensimbi eyingxubevange, insimbi empunga, i-ductile iron, cast aluminium alloy, ingxubevange ye-copper-zinc (ithusi), i-copper-tin alloy (ithusi), ithusi elimsulwa, insimbi efojiwe, insimbi ye-carbon, insimbi ye-chrome, i-chrome- insimbi ye-vanadium, insimbi ye-chrome-nickel, insimbi ye-chrome-molybdenum, insimbi ye-chrome-manganese-silicon, insimbi enamandla kakhulu, insimbi engagqwali, njll.
Shinsimbiumhloli wokuqina:Ikakhulu isetshenziselwa ukukala ubulukhuni bepulasitiki elithambile kanye nenjoloba yobulukhuni obujwayelekile, njengenjoloba ethambile, irabha yokwenziwa, amarola enjoloba okuphrinta, ama-thermoplastic elastomers, isikhumba, njll. Isetshenziswa kabanzi embonini yepulasitiki, imboni yenjoloba nezinye izimboni zamakhemikhali, okuhlanganisa ubulukhuni bepulasitiki eqinile nerabha eqinile, njengezinhlaka eziqinile ze-thermoplastic, izinto zaphansi, amabhola e-bowling, njll. Ikakhulukazi ilungele ukukala ubulukhuni esizeni berabha nemikhiqizo eqediwe yepulasitiki.
Umhloli wokuqina we-Webster:esetshenziswa ukuhlola ingxubevange ye-aluminium, ithusi elithambile, ithusi eliqinile, ingxubevange ye-aluminium eqinile nensimbi ethambile.
I-Barcol Hardness Tester:Ilula futhi ifaneleka, leli thuluzi seliyindinganiso emkhakheni noma ukuhlolwa kwempahla engavuthiwe yemikhiqizo yokugcina, njengamabhodi e-fiberglass, amapulasitiki, i-aluminium kanye nezinto ezihlobene. Leli thuluzi lihlangabezana nezidingo ze-American Fire Protection Association NFPA1932 futhi lisetshenziselwa ukuhlolwa kwenkundla yezitebhisi zomlilo emazingeni aphezulu okushisa. Izinto zokulinganisa: i-aluminium, ingxubevange ye-aluminium, izinsimbi ezithambile, amapulasitiki, i-fiberglass, izitebhisi zomlilo, izinto eziyinhlanganisela, irabha nesikhumba.
