I-YY-3000 ye-Rapid Rapid yePlastometer yeNdalo
I. Isishwankathelo
Umgaqo osisiseko wokusebenza wemitha yeplastiki ekhawulezayo kukuba: Xa iipleyiti ezimbini ezihambelanayo ezinobushushu be-100 ℃, apho ipleyiti yoxinzelelo ephezulu igxininiswe kwi-beam ehambayo kwaye ipleyiti yoxinzelelo ephantsi yipleyiti ehambayo ehambayo, isampuli ixinzelelwe kwi-1mm kuqala kwaye igcinwe kwi-15s, ukuze ubushushu besampuli bufikelele kwiqondo lokushisa elichaziweyo, ixabiso lexabiso le-10N lisetyenzisiweyo, ixabiso lexabiso le-10N lisetyenziswayo. iipleyiti ezihambelanayo zilinganiselwa kwi-15s ngokuchaneka kwe-0.01mm. Eli xabiso limele ukunyanzeliswa komzekelo, oko kukuthi ixabiso leplastiki elikhawulezayo lePo.
Rapid plasticity imitha zingasetyenziswa ukulinganisa inqanaba ukugcinwa kweplastiki yendalo (PRI), indlela esisiseko yile: isampuli efanayo yahlulwe ngamaqela amabini, elinye iqela ngqo ukulinganisa ixabiso lokuqala leplastiki Po, elinye iqela ibekwe kwibhokisi ekhethekileyo ukwaluphala, kwi 140 ± 0.2 ℃ lobushushu, emva kokwaluphala imizuzu engama-30, walinganisa ixabiso layo leplastiki P30, iiseti ezimbini calculation data:
PRI= ×100％
Pom------------Iplastiki yeMedian ngaphambi kokuguga
P.30m-----------Iplastiki yeMedian emva kokuguga
Ixabiso le-PRI libonisa iimpawu ze-antioxidant ze-rubber yendalo, kwaye ixabiso eliphezulu liphezulu, ngcono i-antioxidant properties.
Esi sixhobo sinokumisela ixabiso leplastiki elikhawulezayo lerabha eluhlaza kunye nerubha engavulwanga, kwaye inokugqiba izinga lokugcinwa kweplastiki (PRI) yerabha eluhlaza yendalo.
Ukuguga kwesampulu: Ibhokisi yokuguga inamaqela ali-16 eetreyi zeesampulu zokuguga, ezinokuthi zibe neminyaka eyi-16 × 3 iisampulu ngaxeshanye, kunye nobushushu bokwaluphala yi-140±0.2℃. Isixhobo sihlangabezana neemfuno zobugcisa ze-ISO2007 kunye ne-ISO2930.
II.Inkcazo yesixhobo
(1)Umamkeli
1.Umgaqo kunye nesakhiwo:
Umninimzi uqulunqwe ngamacandelo amane: umthwalo, imitha yokubonisa i-deformation deformation, ulawulo lwexesha lokuvavanya kunye nendlela yokusebenza.
Umthwalo omiselweyo ofunekayo kuvavanyo uveliswa ngubunzima be-lever. Ngexesha lovavanyo, emva kwe-15s yokufudumeza kwangaphambili, i-coil ye-electromagnetic efakwe kwimitha yeplastiki inamandla, kwaye ubunzima be-lever bulayishiwe, ukuze i-indenter ikhuphe umthwalo kwisampuli yephepha efakwe phakathi kweeplate zoxinzelelo eziphezulu kunye nezantsi, kunye neplastiki yesampuli ibonakaliswe ngesalathisi sokudayela esifakwe kwi-beam yokuphakamisa.
Ukuze ugweme ukulahleka kobushushu kunye nokuqinisekisa ukushisa okungapheliyo, iiplati eziphakamileyo eziphezulu kunye nezantsi zinikezelwa ngeepads ze-adiabatic. Ukuze kuhlangatyezwane neemfuno zovavanyo lwezixhobo zerabha ezithambileyo nezinzima, ngaphezu kokufaka ipleyiti enkulu yokushicilela kunye nobubanzi be-1cm, irabha ethambileyo nenzima inokutshintshwa ukuze kuqinisekiswe ukuba isalathisi sokudayela siphakathi kwe-0.2 kunye ne-0.9mm, kwaye siphucule ukuchaneka kovavanyo.

(2) I-Oven yokuguga ye-PRI
I. Isishwankathelo
I-oven yokuguga ye-PRI yi-oven ekhethekileyo yokuguga yokulinganisa izinga lokugcinwa kweplastiki yerabha yendalo. Ineempawu zokuchaneka kobushushu obungapheliyo, ixesha elichanekileyo, umthamo omkhulu wesampulu kunye nokusebenza ngokulula. Iimpawu zobugcisa ziyahlangabezana neemfuno ze-ISO-2930. Ibhokisi yokuguga yenziwe ngesakhelo se-aluminium exande rhoqo, i-greenhouse, ulawulo lobushushu, ixesha kunye nezinye iindawo. I-thermostat ine-greenhouses ezine eziqhubekayo, ezixhotyiswe ngocingo lombane kunye nombhobho wokutshintshiselana komoya, kwaye yamkela izinto zokugquma kabini. Imekyuri yomoya icinezela umoya omtsha kwigumbi ngalinye elingaguqukiyo ukuze kungene umoya. I-greenhouse nganye eqhubekayo ixhotyiswe nge-rack ye-aluminiyam yesampuli kunye neetereyi ezine zesampulu. Xa i-rack yesampula ikhutshwe, ixesha elingaphakathi kwesixhobo limisiwe, kwaye isampuli yesampuli ityhilwa umva ukuba ivalwe ekungeneni kwe-greenhouse rhoqo.
Iphaneli ye-oven yokuguga inikezelwa ngokubonisa ubushushu bedijithali.
