I-YY-3000 ye-Natural Rubber Rapid Plastometer

I.Isifinyezo

Isimiso esiyisisekelo sokusebenza semitha ye-plasticity esheshayo yile: Lapho amapuleti amabili ahambisanayo anezinga lokushisa elingu-100 ℃, lapho ipuleti yokucindezela ephezulu igxiliwe kugongolo olunyakazayo kanye nepuleti yokucindezela ephansi iyipuleti elihambisanayo eligudlukayo, isampula sicindezelwa ku-1mm kuqala futhi igcinwe ama-15s, ukuze izinga lokushisa lesampula lifinyelele izinga lokushisa elishiwo, inani le-10N lenani elisetshenzisiwe lishintsha inani eliphakathi kwe-10N kanye nenani elilinganiselwe le-10N. amapuleti parallel kukalwa 15s ngokunemba 0.01mm. Leli nani limelela ukucindezelwa kwesifanekiso, okungukuthi inani lepulasitiki elisheshayo elithi Po.

Rapid plasticity imitha ingasetshenziswa ukukala engokwemvelo plastic ukugcinwa rate (PRI), indlela eyisisekelo: isampula efanayo ihlukaniswe ngamaqembu amabili, iqembu elilodwa likalwa ngokuqondile inani plastic Po, elinye iqembu ibekwe ebhokisini ekhethekile ukuguga, at 140 ± 0.2 ℃ izinga lokushisa, ngemva kokuguga imizuzu engu-30, kukalwa ukubaluleka kwawo plastic P30, amasethi amabili calculation idatha:
PRI= ×100％
I-Pom------------Ipulasitiki yeMedian ngaphambi kokuguga
P.30m----------Ipulasitiki yeMedian ngemva kokuguga

Inani le-PRI libonisa izakhiwo ze-antioxidant zenjoloba yemvelo, futhi inani eliphakeme, liba ngcono izakhiwo ze-antioxidant.

Leli thuluzi linganquma inani elisheshayo lepulasitiki lenjoloba eluhlaza kanye nerabha engavuthisiwe, futhi lingaphinda linqume izinga lokugcinwa kwepulasitiki (PRI) lerabha eluhlaza yemvelo.

Isampula yokuguga: Ibhokisi lokuguga linamaqembu angu-16 amathreyi amasampula okuguga, angadala amasampula angu-16×3 ngesikhathi esifanayo, futhi izinga lokushisa lokuguga lingu-140±0.2℃. Ithuluzi lihlangabezana nezidingo zobuchwepheshe ze-ISO2007 kanye ne-ISO2930.

 II.Incazelo yensimbi
(1)Umsingathi
1.Isimiso nesakhiwo:

Umsingathi uqukethe izingxenye ezine: umthwalo, imitha yokubonisa isampula yokuguqulwa, ukulawula isikhathi sokuhlola kanye nendlela yokusebenza.

Umthwalo omisiwe odingekayo ekuhlolweni ukhiqizwa isisindo se-lever. Ngesikhathi sokuhlolwa, ngemva kweminyaka engu-15 yokushisisa kwangaphambili, ikhoyili kagesi efakwe kumitha yepulasitiki inikezwa amandla, futhi isisindo se-lever siyalayishwa, ukuze i-indenter ikhiphe umthwalo kusampula yeshidi efakwe phakathi kwamapuleti okucindezela angaphezulu naphansi, futhi ubupulasitiki besampula buboniswa yinkomba yokudayela efakwe kugongolo oluphakamisayo.

Ukuze ugweme ukulahlekelwa ukushisa futhi uqinisekise izinga lokushisa elihlala njalo, amapuleti okucindezela aphezulu naphansi anikezwa ngama-adiabatic pads. Ukuze kuhlangatshezwane nezidingo zokuhlola zezinto zenjoloba ezithambile neziqinile, ngaphezu kokufaka ipuleti elikhulu lokucindezela elinobubanzi obungu-1cm, irabha ethambile neqinile ingashintshwa ukuze kuqinisekiswe ukuthi inkomba yokudayela iphakathi kuka-0.2 no-0.9mm, futhi ithuthukise ukunemba kokuhlolwa.

(2) I-PRI Ukuguga Ihhavini
I.Isifinyezo

I-ovini yokuguga ye-PRI iyihhavini yokuguga ekhethekile yokulinganisa izinga lokugcinwa kwepulasitiki yenjoloba yemvelo. Inezici zokunemba okuphezulu kokushisa okungaguquki, isikhathi esinembile, umthamo omkhulu wesampula nokusebenza okulula. Izinkomba zobuchwepheshe zihlangabezana nezidingo ze-ISO-2930. Ibhokisi lokuguga lakhiwa unxande aluminium ifreyimu abamba ukushisa njalo, ukulawula izinga lokushisa, isikhathi kanye nezinye izingxenye. I-thermostat inezindlu zokushisa ezine ezingaguquki, ezifakelwe izintambo zikagesi zesithando somlilo kanye nepayipi lokushintshisana komoya, futhi yamukela izinto zokuvikela ezinezingqimba ezimbili. I-Air mercury icindezela umoya omusha ekamelweni ngalinye elingashintshi ukuze kungene umoya. I-greenhouse ngayinye engashintshi ifakwe isampula ye-aluminium yokubeka kanye namathreyi amasampula amane. Uma isampula yokubeka ikhishiwe, isikhathi esingaphakathi kwensimbi siyamiswa, bese isampula rack iphindiselwa emuva ukuze ivalwe emnyango we-greenhouse njalo.
Iphaneli lehhavini eliguga linikezwe isibonisi sokushisa sedijithali.
