Ni irihe tandukaniro riri hagati ya firime ya iPhone 9D na 9H?

9H bivuga gukomera naho 9D bivuga kugabanuka kwa membrane.
Ariko nta 9D nyayo ihari, niyo yaba firime zingahe D yagabanijwemo ibice bitatu gusa: indege, 2.5D, na 3D.
9H bivuga ubukana, mubyukuri bivuga ubukana bwikaramu, ntabwo ubukana bwa Mohs.Ndetse agace k'ikirahure karashobora kurenga ubwo bukomere, nabwo ni gimmick yo kwamamaza.

Gukomera bigabanijwemo:
1. Shushanya gukomera.Ikoreshwa cyane cyane kugereranya urwego rwubworoherane nubukomezi bwamabuye y'agaciro atandukanye.Uburyo nuguhitamo inkoni ifite impera imwe ikomeye kandi imwe yoroshye kurundi, hanyuma ugashushanya ibikoresho byageragejwe kuruhande, hanyuma ukamenya ubworoherane nubukomezi bwibikoresho byapimwe ukurikije umwanya wikibanza.Mu buryo bufite ireme, ibishushanyo bikozwe nibintu bikomeye ni birebire, kandi ibishushanyo bikozwe nibintu byoroshye ni bigufi.
2. Kanda cyane.Ahanini ikoreshwa mubikoresho byicyuma, uburyo nugukanda indenter yerekanwe mubikoresho byageragejwe hamwe numutwaro runaka, hanyuma ukagereranya ubukana bwibikoresho byapimwe nubunini bwa disiki ya plastike yaho hejuru yibikoresho.
Bitewe no gutandukanya indenter, umutwaro nigihe cyo kwikorera, hariho ubwoko bwinshi bwokwerekana indentation, cyane cyane ubukana bwa Brinell, ubukana bwa Rockwell, ubukana bwa Vickers na microhardness.

3. Ongera ukomere.Ahanini ikoreshwa mubikoresho byicyuma, uburyo nugukora inyundo ntoya idasanzwe igwa kubuntu kuva murwego runaka kugirango bigire ingaruka kubikoresho bigomba kugeragezwa, hanyuma ukoreshe ingano yingufu zibitswe (hanyuma zirekurwa) nicyitegererezo mugihe cya inzira yingaruka (binyuze mugusubiza inyundo nto).gusimbuka uburebure) kugirango umenye ubukana bwibikoresho.
Uburyo bwo gupima ubukana bwa Rockwell nuburyo SP y'Abanyamerika Yasabwe na Rockwell mu 1919, ahanini yatsinze amakosa yavuzwe haruguru yibibazo bya Brinell.Indenter ikoreshwa mubukomezi bwa Rockwell ni cone ya diyama ifite inguni ya taper ya 120 ° cyangwa umupira wicyuma ufite diameter ya 1/16 santimetero (santimetero 1 ihwanye na mm 25.4), kandi ubujyakuzimu bwifashishwa nkibanze kugirango uhindure ubukana. agaciro.
