I-HRB-150TS yePlastiki yeBhola yePlastiki yokuJonga uBulukhuni

I-HRB-150TS yePlastiki yeBhola yePlastiki yokuJonga ubuMnandisi boMfanekiso oFakelweyo

Inkcazelo emfutshane:

Iinkcukacha zeMveliso

Iithegi zeMveliso

Intshayelelo:

Umvavanyi wobulukhuni bebhola ye-indentation yenzelwe kwaye yenziwe ngokweemfuno ze-GB3398.1-2008 zePlastiki yoBulukhuni bokuQinisekisa Icandelo le-1 yeBhola ye-Indentation Method kunye ne-ISO 2039-1-2001 yePlastiki yokuQinisekisa iSigaba se-1 yeBhola yeNdlela yokuNxinzelela.

Umgangatho we-ISO 2039-2 uchaza ukumiselwa kwexabiso lobulukhuni ngomatshini wokuvavanya ubulukhuni beRockwell, usebenzisa i-Rockwell ubulukhuni isikali E, L, M kunye ne-R, efana neIndlela yeRockwell.

Isicelo:

I-HRB-150TS yeBhola yePlastiki eIndentity Hardness Tester (4)

Lo mvavanyi wobulukhuni bebhola ungasetyenziselwa ukuvavanya ubulukhuni bezinto kwiiplastiki zobunjineli beemoto, irabha enzima, izinto zokwakha zeplastiki kunye namanye amashishini, kwaye inokusebenza kwaye iprinte idatha.

Ingcaciso yeMveliso:

Ukuqina kweplastiki kubhekiselele kwisakhono semathiriyeli yeplastiki ukuxhathisa ukucinezelwa kuyo ngenye into eqinileyo ethathwa ngokuba ayizukwenziwa i-elastic and plastic deformation.

Uvavanyo lobulukhuni be-indentation lwebhola yeplastiki kukusebenzisa ibhola yentsimbi kunye nobubanzi obuchaziweyo ukucinezela ngokuthe nkqo kumphezulu wesampuli phantsi kwesenzo somthwalo wovavanyo, kwaye ufunde ubunzulu bokungena emva kokubamba ixesha elithile.Ixabiso lobunzima lifunyanwa ngokubala okanye ukujonga itafile.

I-1, ubukhulu besampulu abukho ngaphantsi kwe-4mm, isantya sokulayisha sinokuhlengahlengiswa ngaphakathi kwemizuzwana ye-2-7, ngokuqhelekileyo imizuzwana ye-4-6, kunye nexesha lokulayisha imizuzwana engama-30 okanye imizuzwana engama-60;Ubungakanani bomthwalo kufuneka bukhethwe ngokobunzima obulindelekileyo besampuli, kwaye ubunzima obuphezulu bunokukhetha umthwalo omkhulu;Ngaphandle koko, umthwalo omncinci usetyenziswa.Ukuba ubunzima besampulu abukwazi ukuqikelelwa, kufuneka buphuculwe ngokuthe ngcembe ukusuka kumthwalo omncinci, ukuze ungonakalisi i-indenter yebhola kunye nesampuli;Ngokuqhelekileyo, uvavanyo lunokuthi luqhutywe ngokude nje umthwalo ukhethwa ngokweemfuno ezichaziweyo zesampuli.

I-2, ubulukhuni be-indentation yebhola bubhekiselele kububanzi obuchaziweyo bebhola yentsimbi, phantsi kwesenzo somthwalo wokuvavanya ucinezele ngokuthe nkqo kumphezulu wesampuli, ugcine ixesha elithile, uxinzelelo oluqhelekileyo kwindawo nganye yeyunithi ukuya kwi-Kgf / mm2 okanye i-N / mm2 ebonakalisiweyo
