Umhloli wobulukhuni usetyenziselwa uvavanyo lobulukhuni bentsimbi ekhandiweyo kunye nentsimbi ephoswe ngesakhiwo esingalinganiyo.Ubunzima bentsimbi ekhandiweyo kunye nentsimbi engwevu inembalelwano elungileyo kunye novavanyo olunzima.Ingasetyenziselwa iintsimbi ezingezizo i-ferrous kunye nentsimbi ethambileyo, kwaye i-indenter yebhola encinci inokulinganisa ubungakanani obuncinci kunye nezixhobo ezincinci.
Ukuqina kubhekiselele kwisakhono semathiriyeli ukuchasa ukuguqulwa kwendawo, ngakumbi ukuguqulwa kweplastiki, ukunyanzeliswa okanye imikrwelo, kwaye yenye yezalathisi ezibalulekileyo zokusebenza kwezixhobo zetsimbi.Ngokubanzi, okukhona ukuqina kokuqina, kokukhona ukuxhathisa ukunxiba bhetele.Isalathiso sokulinganisa ukuthamba kunye nobunzima bezinto eziphathekayo.Ngokweendlela ezahlukeneyo zokuvavanya, ubulukhuni buhlulwe kwiintlobo ezintathu.Makhe sijonge nganye kuzo:
Ukuqina komkrwelo:
Isetyenziselwa ikakhulu ukuthelekisa ukuthamba kunye nobunzima beeminerali ezahlukeneyo.Indlela yokukhetha intonga enesiphelo esinye esinzima kunye nesinye isiphelo esithambileyo, ukudlula izinto eziza kuvavanywa kunye nentonga, kwaye unqume ubulukhuni bezinto eziza kuvavanywa ngokwendawo yokukrala.Xa sithetha ngokomgangatho, izinto eziqinileyo zenza imikrwelo emide kwaye izinto ezithambileyo zenza imikrwelo emifutshane.
Ubulukhuni bokucinezela:
Ikakhulu isetyenziselwa izinto zetsimbi, indlela kukusebenzisa umthwalo othile ukucinezela i-indenter echaziweyo kwizinto eziza kuvavanywa, kwaye uthelekise ukuthamba kunye nokuqina kwezinto eziza kuvavanywa ngobungakanani bokuguqulwa kweplastiki yendawo kumphezulu we izinto eziphathekayo.Ngenxa yomahluko we-indenter, umthwalo kunye nobude bexesha lomthwalo, kukho iintlobo ezininzi zobunzima bokungena, ngakumbi kubandakanywa ukuqina kwe-Brinell, ukuqina kwe-Rockwell, ubulukhuni beVickers kunye nobunzima obuncinci.
Ukuqina kwakhona:
Ikakhulu isetyenziselwa izinto zetsimbi, indlela kukwenza isando esikhethekileyo esincinci siwe ngokukhululekileyo ukusuka kumphakamo othile ukuchaphazela isampuli yezinto eziza kuvavanywa, kwaye usebenzise isixa samandla oxinzelelo agcinwe (kwaye akhululwe) kwisampulu ngexesha lovavanyo. impembelelo (ngokubuyiswa kwehamile encinci) umlinganiselo wobude bomtsiba) ukumisela ukuqina kwezinto.
Umvavanyi wobulukhuni oveliswe nguShandong Shancai / Laizhou Laihua Testing Instrument luhlobo lwesixhobo sokuvavanya ubulukhuni be-indentation, esibonisa ukukwazi kwezinto eziphathekayo ukuchasana nokungena kwezinto ezinzima kwindawo yayo.Zingaphi iindidi ezikhoyo?
1. I-Brinell Hardness Tester: Isetyenziselwa ukulinganisa ubunzima bentsimbi, isinyithi, isinyithi esingenawo i-ferrous kunye ne-alloys ethambileyo.Yindlela yokuvavanya ubulukhuni obuphezulu.
2. Umhloli wobulukhuni be-Rockwell: umhloli wobunzima be-Rockwell onokuvavanya ubulukhuni besinyithi ngokuchukumisa isampuli kwelinye icala.Ixhomekeke kumandla kazibuthe ukuze ibhengeze intloko yomvavanyi wobulukhuni beRockwell kumphezulu wentsimbi, kwaye ayifuni kuxhasa isampuli.
3. I-Vickers Hardness Tester: I-Vickers Hardness Tester yimveliso ye-high-tech edibanisa i-optoelectronics kunye ne-electronics.Umatshini unoveli ngokumila, unokuthembeka okulungileyo, ukusebenza kunye nokuqondakala.Izixhobo zokuvavanya ubulukhuni be-S kunye ne-Knoop.
4. Umvavanyi wobulukhuni be-Brockwell: Umhloli wobulukhuni be-Brockwell ufanelekile ukumisela ubulukhuni besinyithi, isinyithi esingenamvubelo, i-alloys eqinile, i-carburized layers kunye neengqimba eziphathwe ngamachiza.
5. Umhloli we-Microhardness: Umhloli we-Microhardness sisixhobo esichanekileyo sokuvavanya iimpawu zezixhobo zetsimbi kumatshini, i-metallurgy kunye namanye amashishini, kwaye isetyenziswa ngokubanzi kumashishini ahlukeneyo.
6. I-Leeb Hardness Tester: Umgaqo wayo osisiseko kukuba umzimba wempembelelo onobunzima obuthile uchaphazela umphezulu wesampuli phantsi kwamandla athile ovavanyo, kwaye ulinganisa isantya sempembelelo kunye nesantya sokubuyela kwakhona somzimba wempembelelo kumgama we-1 mm ukusuka kumandlalo wovavanyo. Umphezulu wesampulu, usebenzisa imigaqo yombane wombane, umbane olingana nesantya owenziweyo.
7. Umhloli we-Webster hardness tester: Umgaqo we-Webster hardness tester yi-indenter yensimbi enzima enemilo ethile, ecinezelekile kumphezulu wesampuli phantsi komgangatho oqhelekileyo wokuvavanya entwasahlobo.
8. I-Barcol Hardness Tester: I-indentation tester yobunzima.Icinezela i-indenter ethile kwisampulu phantsi kwesenzo se-spring force eqhelekileyo, kwaye imisela ubulukhuni besampuli ngobunzulu be-indentation.
