YY-3000 Natural Rubber Rapid Plastometer

I.Summary

Nheyo yekutanga yekushanda kweiyo kukurumidza mapurasitiki mita ndeye: Kana mahwendefa maviri akafanana ane tembiricha ye100 ℃, umo iyo yekumusoro yekumanikidza ndiro yakagadzikwa padanda rinofamba uye yakaderera dhizaini ndiro inofambiswa parallel ndiro, sampu inomanikidzwa kusvika 1mm kutanga uye inochengeterwa 15s, kuitira kuti tembiricha yemuenzaniso isvike pane yakatarwa tembiricha, kukosha kweiyo 10N kukosha kweiyo 10N kukosha kwakaiswa pakati pechinhambwe cheiyo 10N. parallel plates inoyerwa 15s nekururama kwe0.01mm. Ukoshi uhwu hunomiririra kusimba kweiyo specimen, kureva kukurumidza kwepurasitiki kukosha Po.

Rapid plasticity mita inogona kushandiswa kuyera yakasikwa purasitiki retention rate (PRI), iyo yakakosha nzira ndeye: sample imwe yakakamurwa kuita mapoka maviri, rimwe boka rakananga kuyerwa kwekutanga kwepurasitiki kukosha Po, rimwe boka rinoiswa mubhokisi rekuchembera, pa140 ± 0.2 ℃ tembiricha, mushure mekuchembera kwemaminetsi makumi matatu, yakayera kukosha kwayo kwepurasitiki P30, iwo maviri seti calculation yedata:
PRI= ×100 ％
Pom-----------Median plasticity isati yachembera
P.30m----------Median plasticity mushure mekukwegura

Iyo PRI kukosha inoratidza iyo antioxidant zvimiro zverabha yechisikigo, uye iyo yakakwirira kukosha, zviri nani iyo antioxidant zvivakwa.

Ichi chiridzwa chinogona kuona kukosha kwepurasitiki yeraw mbishi uye isina kuvhurika rabha, uye inogona zvakare kuona chiyero chekuchengetedza epurasitiki (PRI) yerabha yakasikwa.

Sample kuchembera: Bhokisi rekuchembera rine 16 mapoka ekuchembera sampuli matireyi, anogona kuchembera 16×3 samples panguva imwe chete, uye tembiricha yekuchembera i140±0.2℃. Chiridzwa chinosangana nezvinodiwa zvehunyanzvi zve ISO2007 uye ISO2930.

1.Nheyo uye chimiro:

Iyo saiti inoumbwa nezvikamu zvina: mutoro, sampuli deformation kuratidza mita, bvunzo nguva yekudzora uye maitiro ekushanda.

Iyo yakagadziriswa mutoro unodiwa bvunzo inogadzirwa nerevheti uremu. Munguva yekuyedzwa, mushure memakore gumi nemashanu ekutanga kupisa, iyo electromagnetic coil yakaiswa mu plasticity mita inopihwa simba, uye uremu hwerevhisi hunoremerwa, kuitira kuti indenter iite mutoro papepa remuenzaniso rakaiswa pakati pepamusoro nepasi pepureti yekumanikidza, uye plastiki yemuenzaniso inoratidzwa nedhiyari chiratidzo chakaiswa padanda rekusimudza.

Kuti udzivise kurasikirwa nekupisa uye kuve nechokwadi chekushisa chinogara chiripo, mahwendefa epamusoro uye epasi ekumanikidza anopihwa adiabatic pads. Kuti zvizadzise zvinodikanwa zvekuyedzwa zvezvakapfava uye zvakaoma zverabha zvinhu, pamusoro pekuisa hombe yekutsikirira ndiro ine dhayamita ye1cm, iyo yakapfava uye yakaoma rabha inogona kutsiviwa kuve nechokwadi chekuti dial chiratidzo chiri pakati pe0.2 ne0.9mm, uye nekuvandudza bvunzo chaiyo.

(2) PRI Kuchembera Ovheni
I.Summary

PRI kuchembera hovhoni yakasarudzika yekuchembera yekuyera mwero wekuchengetedza epurasitiki yerabha rechisikigo. Iyo ine hunhu hwehunyoro hwekushisa nguva dzose, nguva chaiyo, yakakura sampuli kugona uye nyore kushanda. Iyo tekinoroji zviratidzo zvinosangana nezvinodiwa zve ISO-2930. Bhokisi rekuchembera rinoumbwa nerectangular aluminium furemu inogara ichipisa, tembiricha kutonga, nguva uye zvimwe zvikamu. Iyo thermostat ine magreenhouse mana anogara aripo, ayo akashongedzerwa nemagetsi muchoto waya uye mhepo yekutsinhana pombi, uye inotora kaviri-layer insulation material. Mhepo mercury inomanikidza mweya mutsva mukamuri yega yega yekufefetera. Imwe neimwe inogara yakasvibira greenhouse yakashongedzerwa nealuminium sampu rack uye mana emuenzaniso matireyi. Kana iyo sampuli rack inoburitswa kunze, nguva mukati mechiridzwa inomiswa, uye sampuli rack inosundirwa kumashure kuti ivharwe pamusuwo weinogara greenhouse.
Iyo pani yevheni yekuchembera inopihwa nedhijitari tembiricha inoratidzira.
