Inqanaba 1: 0.325 kg = (Intonga yePiston + Ipani yokuLinganisa + Umkhono wokuGuqula + Ubunzima obuyiNombolo 1) = 3.187 N

Inqanaba lesi-2: 1.200 kg = (0.325 + Inani lesi-2 0.875 Ubunzima) = 11.77 N

Inqanaba lesi-3: 2.160 kg = (0.325 + Inani lesi-3 1.835 Ubunzima) = 21.18 N

Inqanaba lesi-4: 3.800 kg = (0.325 + Inani lesi-4 3.475 Ubunzima) = 37.26 N

Inqanaba lesi-5: 5.000 kg = (0.325 + Inani 5 4.675 Ubunzima) = 49.03 N

Inqanaba lesi-6: 10.000 kg = (0.325 + Inani 5 4.675 Ubunzima + Inani 6 5.000 Ubunzima) = 98.07 N

Inqanaba lesi-7: 12.000 kg = (0.325 + Inani 5 4.675 Ubunzima + Inani 6 5.000 + Inani 7 2.500 Ubunzima) = 122.58 N

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

Impazamo enxulumene nobunzima bobunzima yi ≤ 0.5%.

3. Uluhlu lobushushu: 50°C ~300°C

4. Uzinzo lobushushu: ± 0.5°C

5. Ubonelelo lwaMandla: 220V ± 10%, 50Hz

6. Iimeko zeNdawo yokuSebenza:

Ubushushu obuphakathi: 10°C ukuya kuma-40°C;

Umswakama oqhelekileyo: 30% ukuya kuma-80%;

Akukho Medium Yonakalisayo Kwiindawo Ezingqongileyo;

Ulwakhiwo kunye noMgaqo wokuSebenza:

Umvavanyi wezinga lokuhamba kwamanzi anyibilikisiweyo luhlobo lwemitha yeplastiki ephumayo. Phantsi kweemeko ezithile zobushushu, isampuli eza kuvavanywa ifudunyezwa ibe yimeko enyibilikisiweyo sisithando sobushushu obuphezulu. Isampuli enyibilikisiweyo emva koko ikhutshwa ngomngxuma omncinci onobubanzi obuthile phantsi komthwalo wobunzima obumiselweyo. Kwimveliso yeplastiki yamashishini emizi-mveliso kunye nophando lwamaziko ophando lwesayensi, "izinga lokuhamba kwamanzi anyibilikisiweyo" lidla ngokusetyenziswa ukumela ukugeleza, i-viscosity kunye nezinye iipropati zomzimba zezinto zepolymer kwimeko enyibilikisiweyo. Oko kubizwa ngokuba yi-melt index kubhekisa kubunzima obuphakathi kwecandelo ngalinye lesampuli ekhutshweyo eguqulwe yaba yimali ephumayo kwimizuzu eli-10.

Isixhobo sokutyibilika (ubunzima) siboniswa yi-MFR, apho iyunithi iyi: iigram ngemizuzu eli-10 (g/min).

Ifomula yile:

I-MFR(θ, mnom) = tref . m/t

Apho: θ —- ubushushu bovavanyo

Mnom— - umthwalo oqhelekileyo (Kg)

m —- ubunzima obuphakathi bomda, g

tref —- ixesha lesalathiso (imizuzu eli-10), S (imizuzwana engama-600)

t ——- ixesha eliphakathi lokuphela, s

Umzekelo:

Iqela leesampuli zeplastiki lanqunyulwa rhoqo emva kwemizuzwana engama-30, kwaye iziphumo zobunzima becandelo ngalinye zazi: 0.0816 grams, 0.0862 grams, 0.0815 grams, 0.0895 grams, 0.0825 grams.

Ixabiso eliphakathi m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (iigram)

Faka kule fomyula: MFR = 600 × 0.0843 / 30 = 1.686 (iigram ngemizuzu eli-10)
