Incazelo emfushane:

Izicelo:

Isivivinyo sezinga lokugeleza kokuncibilika kwe-YYP-400E siyithuluzi lokunquma ukusebenza kokugeleza kwama-polymer epulasitiki emazingeni okushisa aphezulu ngokuhambisana nendlela yokuhlola echazwe ku-GB3682-2018. Sisetshenziselwa ukukala izinga lokugeleza kokuncibilika kwama-polymer njenge-polyethylene, i-polypropylene, i-polyoxymethylene, i-ABS resin, i-polycarbonate, i-nylon, kanye ne-fluoroplastics emazingeni okushisa aphezulu. Sisebenza ekukhiqizweni nasekucwaningweni emafektri, emabhizinisini nasezikhungweni zocwaningo lwesayensi.

Amapharamitha obuchwepheshe ayinhloko:

Izinga 1: 0.325 kg = (Induku yePiston + Ipani Lokukala + Isikhwama Sokuvikela + Isisindo Senombolo 1) = 3.187 N

Izinga 2: 1.200 kg = (0.325 + Inombolo 2 0.875 Isisindo) = 11.77 N

Izinga 3: 2.160 kg = (0.325 + Inombolo 3 1.835 Isisindo) = 21.18 N

Izinga 4: 3.800 kg = (0.325 + Inombolo 4 3.475 Isisindo) = 37.26 N

Izinga 5: 5.000 kg = (0.325 + Inombolo 5 4.675 Isisindo) = 49.03 N

Izinga 6: 10.000 kg = (0.325 + Inombolo 5 4.675 Isisindo + Inombolo 6 5.000 Isisindo) = 98.07 N

Izinga 7: 12.000 kg = (0.325 + Inombolo 5 4.675 Isisindo + Inombolo 6 5.000 + Inombolo 7 2.500 Isisindo) = 122.58 N

Izinga 8: 21.600 kg = (0.325 + Inombolo 2 0.875 Isisindo + Inombolo 3 1.835 + Inombolo 4 3.475 + Inombolo 5 4.675 + Inombolo 6 5.000 + Inombolo 7 2.500 + Inombolo 8 2.915 Isisindo) = 211.82 N

Iphutha elihlobene lesisindo liyi-≤ 0.5%.

3. Ububanzi Bokushisa: 50°C ~300°C

4. Ukuqina Kwezinga Lokushisa: ± 0.5°C

5. Ukunikezwa Kwamandla: 220V ± 10%, 50Hz

6. Izimo Zendawo Yokusebenza:

Izinga Lokushisa Eliphakathi: 10°C kuya ku-40°C;

Umswakama ohlobene: 30% kuya ku-80%;

Akukho Medium Egqwalisayo Ezindaweni Ezizungezile;

Akukho Umoya Oqinile Ongenawo Amandla;

Ayinawo Ukudlidliza noma Ukuphazamiseka Kwensimu Yama-Magnetic Okunamandla.

7. Ubukhulu Bezinsimbi: 280 mm × 350 mm × 600 mm (Ubude × Ububanzi ×Ukuphakama)

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Isakhiwo kanye nesimiso sokusebenza:

Umhloli wezinga lokugeleza kokuncibilika uhlobo lwemitha yepulasitiki yokuncibilika. Ngaphansi kwezimo zokushisa ezicacisiwe, isampula ezohlolwa ishiswa ibe sesimweni esincibilikile ngesithando sokushisa esiphezulu. Isampula encibilikile ibe isikhishwa ngembobo encane enobubanzi obucacisiwe ngaphansi komthwalo wesisindo esinqunyiwe. Ekukhiqizweni kwepulasitiki kwamabhizinisi ezimboni kanye nocwaningo lwezikhungo zocwaningo lwesayensi, "izinga lokugeleza kokuncibilika (ubuningi)" livame ukusetshenziswa ukumela ukugeleza, i-viscosity kanye nezinye izakhiwo zomzimba zezinto ze-polymer esimweni esincibilikile. Okubizwa ngokuthi i-melt index kubhekisela esisindweni esimaphakathi sengxenye ngayinye yesampula encibilikisiwe eguqulwe ibe inani lokuncibilika ngemizuzu eyi-10.

Ithuluzi lokugeleza kwesilinganiso sokuncibilika (ubuningi) liboniswa yi-MFR, kanti iyunithi iyi: amagremu ngemizuzu eyi-10 (g/min).

Ifomula ithi:

I-MFR(θ, mnom) = tref . m/t

Kuphi: θ —- izinga lokushisa lokuhlola

Mnom— - umthwalo ojwayelekile (Kg)

m —- isisindo esimaphakathi somkhawulo, g

isikhathi sokubhekisela (imizuzu eyi-10), S (amasekhondi angu-600)

t ——- isikhawu sesikhathi sokuphela, s

Isibonelo:

Iqembu lamasampula epulasitiki lasikwa njalo ngemizuzwana engama-30, futhi imiphumela yesisindo sengxenye ngayinye yayiyi: amagremu angu-0.0816, amagremu angu-0.0862, amagremu angu-0.0815, amagremu angu-0.0895, amagremu angu-0.0825.

Inani elimaphakathi m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (amagremu)

Faka esikhundleni sefomula: MFR = 600 × 0.0843 / 30 = 1.686 (amagremu ngemizuzu eyi-10)
