Umvavanyi wobulukhuni sisixhobo sokulinganisa ubulukhuni bemathiriyeli. Ngokwezixhobo ezahlukeneyo ezilinganiswayo, umvavanyi wobulukhuni unokusetyenziswa kwiindawo ezahlukeneyo. Abanye abavavanyi bobulukhuni basetyenziswa kwishishini lokulungisa oomatshini, kwaye ubukhulu becala balinganisa ubulukhuni bemathiriyeli yentsimbi. Ezinje: Brinell umvavanyi ubulukhuni, Rockwell ubulukhuni umvavanyi, Leeb ubulukhuni tester, Vickers umvavanyi ubulukhuni, microhardness umvavanyi, Shore ubulukhuni umvavanyi, Webster ubulukhuni umvavanyi njl. Imida yesicelo ethile yaba bavavanyi ubulukhuni ngolu hlobo lulandelayo:
Brinell ubulukhuni tester:ikakhulu isetyenziselwa uvavanyo lobulukhuni bentsimbi ekhandiweyo kunye nentsimbi ekhatywayo enesakhiwo esingalinganiyo. Ukuqina kweBrinell yentsimbi ekhandiweyo kunye nentsimbi engwevu inembalelwano elungileyo kunye novavanyo lokuqina. Uvavanyo lobulukhuni beBrinell lunokusetyenziselwa iintsimbi ezingenayo i-ferrous kunye nentsimbi ethambileyo. I-indenter yebhola encinci inokulinganisa ubungakanani obuncinci kunye nezixhobo ezibhityileyo, kwaye ilinganise iindawo zokulungisa ubushushu kunye namasebe okuhlola umzi-mveliso weefektri ezahlukeneyo zoomatshini. I-Brinell hardness tester isetyenziswa kakhulu ekuhloleni imathiriyeli ekrwada kunye neemveliso ezigqityiweyo. Ngenxa yokungeniswa okukhulu, ngokuqhelekileyo ayisetyenziselwa ukuhlolwa kwemveliso egqityiweyo.
Rockwell ubulukhuni umvavanyi:Vavanya iintlobo ngeentlobo zesinyithi kunye ne-non-ferrous, vavanya ubulukhuni bentsimbi ecinyiweyo, intsimbi ecinyiweyo kunye nobushushu, intsimbi ene-annealed, i-case-hardened steel, iipleyiti ezinobunzima obahlukeneyo, imathiriyeli ye-carbide, imathiriyeli ye-metallurgy yomgubo, i-thermal spray, i-castings epholileyo, i-castings enokuthenjwa. , ii-alloys ze-aluminiyam, intsimbi yokuthwala, iipleyiti zetsimbi eziqinileyo, njl.
Superficial Rockwell Hardness Tester:Isetyenziselwa ukuvavanya ubulukhuni bentsimbi yentsimbi, umbhobho wodonga oluncinci, intsimbi eqinile kunye namalungu amancinci, i-alloy eqinile, i-carbide, i-case hardened, i-sheet hardened, i-hardened sheet, intsimbi eqinile, i-quenched and tempered steel, intsimbi epholileyo, isinyithi, i-aluminium, ubhedu, i-magnesium kunye nezinye iintsimbi ze-alloy.
Umvavanyi wobulukhuni beVickers: ukulinganisa iindawo ezincinci, iipleyiti zetsimbi ezibhityileyo, iifoyile zetsimbi, iishiti ze-IC, iingcingo, iileya eziqinileyo, iileya ze-electroplated, iglasi, ubucwebe kunye neeseramics, isinyithi esinesinyithi, isinyithi esingeyontsimbi, iishiti ze-IC, iingubo zomphezulu, iintsimbi ezilaminethiweyo; iglasi, iiseramics, iagate, amatye anqabileyo, njl.; ubunzulu kunye novavanyo lobulukhuni begradient yeeleya zekhabhoni kunye nokucima iileya ezilukhuni. Ukusetyenzwa kwehardware, ishishini lombane, izincedisi zokungunda, ishishini lokubukela.
Knoopumvavanyi wobulukhuni:isetyenziselwa ngokubanzi ukulinganisa ubuncinci bezinto ezincinci kunye nezincinci, iingubo zokungena phezulu kunye nezinye iisampuli, kunye nokulinganisa ubulukhuni be-Knoop bezinto ezinqabileyo kunye nezilukhuni ezifana neglasi, i-ceramics, i-agate, amatye anqabileyo, njl njl., ububanzi obusebenzayo: unyango lobushushu, i-carburization, ukucima umaleko wokuqina, ukwambathisa umphezulu, intsimbi, iintsimbi ezingezizo i-ferrous kunye neenxalenye ezincinci nezincinci, njl.
Leeb umvavanyi wobulukhuni:intsimbi kunye nentsimbi, intsimbi yentsimbi, intsimbi engwevu, isinyithi sentsimbi, intsimbi ye-aluminium, i-alloy ye-copper-zinc (ubhedu), i-copper-tin ialloy (ubhedu), ubhedu olusulungekileyo, isinyithi esibunjiweyo, intsimbi ye-carbon, i-chrome steel, i-chrome- intsimbi ye-vanadium, intsimbi ye-chrome-nickel, intsimbi ye-chrome-molybdenum, intsimbi ye-chrome-manganese-silicon, intsimbi yokuqina okuphezulu kakhulu, intsimbi engenasici, njl.
Shintsimbiumvavanyi wobulukhuni:Ikakhulu isetyenziselwa ukulinganisa ubulukhuni beeplastiki ezithambileyo kunye nerabha yobulukhuni eqhelekileyo, njengerabha ethambileyo, irabha yokwenziwa, iirola zerabha yoshicilelo, i-thermoplastic elastomers, ufele, njl. ukuqina kweeplastiki eziqinileyo kunye nerabha eqinile, njenge-thermoplastic hard resins, izinto zomgangatho, iibhola zokubhola, njl. ifanelekile kwisiza sokulinganisa ubulukhuni berabha kunye neemveliso zeplastiki ezigqityiweyo.
Webster ubulukhuni umvavanyi:esetyenziselwa ukuvavanya i-aluminium alloy, ubhedu oluthambileyo, ubhedu oluqinileyo, i-alloy ye-aluminium enzima kakhulu kunye nentsimbi ethambileyo.
Barcol Hardness Tester:Ilula kwaye ifanelekile, esi sixhobo siye saba ngumgangatho kwintsimi okanye uvavanyo lwezinto eziluhlaza zeemveliso zokugqibela, ezifana neebhodi ze-fiberglass, iiplastiki, i-aluminium kunye nezinto ezinxulumene nazo. Esi sixhobo sihlangabezana neemfuno ze-American Fire Protection Association NFPA1932 kwaye isetyenziselwa ukuvavanywa kwintsimi yezitebhisi zomlilo kwiqondo lokushisa eliphezulu. Izinto zokulinganisa: i-aluminiyam, i-alloys ye-aluminiyam, isinyithi esithambileyo, iiplastiki, i-fiberglass, iileli zomlilo, izinto ezidibeneyo, irabha kunye nesikhumba.
