HRB-150 Ibikoresho bya plastiki umupira

Ibisobanuro bigufi:

Ibisobanuro birambuye

Ibicuruzwa

Intangiriro:

Umupira undentation Hardness Tester yateguwe kandi yakozwe hakurikijwe ibisabwa na GB339.1-2008.

Standard Iso 2039-2 isobanura kugena agaciro gakomeye hamwe na mashini igoye yo gupima, ukoresheje gukomera gukomera umunzani e, l, m na r, bisa naUburyo bwa Rockwell.

Gusaba:

Uyu mupira undentation Hardness Dester irashobora gukoreshwa mugupima gukomera kwibikoresho muri plastiki yubuhanga, reberi ikomeye, ibikoresho byubaka bya plastike nibindi nganda, kandi birashobora gutunganya no gucamo amakuru.

Ibisobanuro by'ibicuruzwa:

Gukomera kwa plastike bivuga ubushobozi bwibikoresho bya pulasitike kugirango barwanye kubikwa muribindi kintu gikomeye gifatwa nkicyitegererezo cya elastiki na plastike.

Indentation Ikizamini cyumupira cya pulasitike ni ugukoresha umupira wicyuma hamwe na diameter yagenwe kugirango uhamagare hejuru yicyitegererezo mugikorwa cyikizamini cyo kwipimisha, no gusoma indentation yimbitse nyuma yo gufata igihe runaka. Agaciro katoroshye kuboneka mugukaba cyangwa kureba kumeza.

1, ubunini bwicyitegererezo ntabwo ari munsi ya 4mm, umuvuduko wo gupakira urashobora guhinduka mumasegonda 2-7, mubisanzwe amasegonda 4-6, kandi igihe cyo gupakira ni amasegonda 30 cyangwa amasegonda 60; Ingano yumutwaro igomba gutorwa ukurikije ubushishozi bwicyitegererezo, kandi ubuto bworoshye bushobora guhitamo umutwaro munini; Bitabaye ibyo, umutwaro muto ukoreshwa. Niba gukomera kwicyitegererezo, bigomba kuzamurwa buhoro buhoro mumutwaro muto, kugirango utangiza umupira usohora umupira nicyitegererezo; Mubisanzwe, ikizamini kirashobora gukorwa igihe cyose umutwaro watoranijwe ukurikije ibisabwa byagenwe byicyitegererezo.

2, indentation itoroshye bivuga diameter yagenwe yumupira wamaguru, munsi yibikorwa byikizamini bikabije
