Iithegi zeMveliso

Intshayelelo:

Isivavanyeli sokuqina kwebhola esiyilwe kwaye senziwe ngokweemfuno ze-GB3398.1-2008 Plastic Hardness Determination Part 1 Ball Indection Method kunye ne-ISO 2039-1-2001 Plastic Hardness Determination Part 1 Ball Pressure Method.

I-ISO 2039-2 esemgangathweni ichaza ukumisela ixabiso lobunzima ngomatshini wokuvavanya ubunzima beRockwell, kusetyenziswa izikali zobunzima beRockwell E, L, M kunye ne-R, ezifana nezikaliIndlela yeRockwell.

Isivavanyeli soBulukhuni beBhola yePlastiki yeHRB-150TS (4)

Esi sivavanyi sokuqina kwebhola singasetyenziselwa ukuvavanya ubunzima bezinto ezisetyenziswa kwiiplastiki zobunjineli beemoto, irabha eqinileyo, izixhobo zokwakha zeplastiki kunye namanye amashishini, kwaye sinokuyicubungula kwaye siyiprinte idatha.

Ingcaciso yeMveliso:

Ukuqina kweplastiki kubhekisa kubuchule bezinto zeplastiki bokumelana nokucinezelwa kwenye into eqinileyo ethathwa njengengaguquguqukiyo kwaye iplastiki iguquguquke.

Uvavanyo lokuqina kwebhola yeplastiki kukusebenzisa ibhola yentsimbi enobubanzi obuthile ukuze icinezelwe ngokuthe nkqo kumphezulu wesampuli phantsi kwesenzo somthwalo wovavanyo, kwaye ifunde ubunzulu bokuqina emva kokubamba ixesha elithile. Ixabiso lobunzima lifumaneka ngokubala okanye ukukhangela phezulu etafileni.

1, ubukhulu besampulu abungaphantsi kwe-4mm, isantya sokulayisha singalungiswa kwimizuzwana emi-2-7, ngesiqhelo imizuzwana emi-4-6, kwaye ixesha lokulayisha liyimizuzwana engama-30 okanye imizuzwana engama-60; Ubungakanani bomthwalo kufuneka bukhethwe ngokobunzima obulindelekileyo besampulu, kwaye ubunzima obuphezulu bunokukhetha umthwalo omkhulu; Ngaphandle koko, kusetyenziswa umthwalo omncinci. Ukuba ubunzima besampulu abunakuqikelelwa, kufuneka buphuculwe kancinci kancinci ukusuka kumthwalo omncinci, ukuze kungonakalisa i-indenter yebhola kunye nesampulu; Ngokubanzi, uvavanyo lunokwenziwa logama nje umthwalo ukhethwe ngokweemfuno ezichaziweyo zesampulu.

2, ubulukhuni bokutsalwa kwebhola bubhekisela kububanzi obuchaziweyo bebhola yentsimbi, phantsi kwesenzo somthwalo wovavanyo ocinezelwe ngokuthe nkqo kumphezulu wesampuli, ukugcina ixesha elithile, uxinzelelo oluphakathi kwindawo nganye yeyunithi ukuya kwi-Kgf/mm2 okanye i-N/mm2 echazwe
