Isivivinyo Sokuqina Kokuqina Kwebhola Lepulasitiki le-HRB-150TS

Isivivinyo Sokuqina Kokugoba Kwebhola Lepulasitiki le-HRB-150TS Isithombe Esifakiwe

Incazelo emfushane:

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Isingeniso:

Isihloli sokuqina kwebhola lokugoba siklanywe futhi sakhiqizwa ngokwezidingo ze-GB3398.1-2008 Plastic Hardness Determination Part 1 Ball Indection Method kanye ne-ISO 2039-1-2001 Plastic Hardness Determination Part 1 Ball Pressure Method.

I-ISO 2039-2 ejwayelekile ichaza ukunqunywa kwenani lobulukhuni ngomshini wokuhlola ubulukhuni we-Rockwell, kusetshenziswa izikali zobulukhuni ze-Rockwell E, L, M kanye ne-R, ezifana ne-Indlela yeRockwell.

Isivivinyo Sokuqina Kokugoba Kwebhola Lepulasitiki le-HRB-150TS (4)

Lo mhloli wokuqina kwebhola ungasetshenziswa ukuhlola ubulukhuni bezinto zokwakha kumapulasitiki obunjiniyela bezimoto, irabha eqinile, izinto zokwakha zepulasitiki kanye neminye imboni, futhi ungacubungula futhi uphrinte idatha.

Incazelo Yomkhiqizo:

Ubulukhuni bepulasitiki bubhekisela ekhonweni lezinto zepulasitiki lokumelana nokucindezelwa kwenye into eqinile okubhekwa njengokungabi nokunwebeka kanye nokuguqulwa kwepulasitiki.

Ukuhlolwa kokuqina kwebhola lepulasitiki ukusebenzisa ibhola lensimbi elinobubanzi obuthile ukucindezela ngokuqondile ebusweni besampula ngaphansi kwesenzo somthwalo wokuhlola, nokufunda ukujula kokuqina ngemva kokubamba isikhathi esithile. Inani lokuqina litholakala ngokubala noma ukubheka etafuleni.

1, ubukhulu besampula abungaphansi kuka-4mm, isivinini sokulayisha singalungiswa zingakapheli imizuzwana engu-2-7, ngokuvamile imizuzwana engu-4-6, kanti isikhathi sokulayisha singamasekhondi angu-30 noma imizuzwana engu-60; Usayizi womthwalo kufanele ukhethwe ngokuya ngobunzima obulindelwe besampula, futhi ubunzima obuphezulu bungakhetha umthwalo omkhulu; Ngaphandle kwalokho, kusetshenziswa umthwalo omncane. Uma ubunzima besampula bungenakubikezelwa, kumele buthuthukiswe kancane kancane kusuka kumthwalo omncane, ukuze kungalimazi i-indenter yebhola kanye nesampula; Ngokuvamile, ukuhlolwa kungenziwa inqobo nje uma umthwalo ukhethiwe ngokuya ngezidingo ezicacisiwe zesampula.

2, ubulukhuni bokugoba ibhola bubhekisela kububanzi obucacisiwe bebhola lensimbi, ngaphansi kwesenzo somthwalo wokuhlola ocindezelwe ngokuqondile ebusweni besampula, gcina isikhathi esithile, ingcindezi emaphakathi ngeyunithi ngayinye ibe yi-Kgf/mm2 noma i-N/mm2 evezwe
