Nā noi:

ʻO ka mea hoʻāʻo kahe hoʻoheheʻe YYP-400E kahi mea hana no ka hoʻoholo ʻana i ka hana kahe o nā polymers plastik i nā mahana kiʻekiʻe e like me ke ʻano hoʻāʻo i hoʻākāka ʻia ma GB3682-2018. Hoʻohana ʻia ia e ana i ka kahe hoʻoheheʻe o nā polymers e like me ka polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon, a me nā fluoroplastics i nā mahana kiʻekiʻe. Pili ia i ka hana ʻana a me ka noiʻi ʻana i nā hale hana, nā ʻoihana a me nā ʻoihana noiʻi ʻepekema.

Nā palena loea nui:

1. ʻĀpana hoʻokuʻu extrusion:

Ke anawaena o ka puka hoʻokuʻu: Φ2.095 ± 0.005 mm

Ka lōʻihi o ke awa hoʻokuʻu: 8.000 ± 0.007 millimeters

ʻO ke anawaena o ka cylinder hoʻouka: Φ9.550 ± 0.007 mm

Ka lōʻihi o ka paukū hoʻouka: 152±0.1 mm

Ke anawaena o ke poʻo o ke koʻokoʻo piston: 9.474 ± 0.007 mm

Ka lōʻihi o ke poʻo o ke koʻokoʻo piston: 6.350±0.100 mm

2. Mana Hoʻāʻo Maʻamau (ʻEwalu Pae)

Pae 1: 0.325 kg = (Piston Rod + Weighing Pan + Insulasi Sleeve + Helu 1 Kaumaha) = 3.187 N

Pae 2: 1.200 kg = (0.325 + Helu 2 0.875 Kaumaha) = 11.77 N

Pae 3: 2.160 kg = (0.325 + Helu 3 1.835 Kaumaha) = 21.18 N

Pae 4: 3.800 kg = (0.325 + Helu 4 3.475 Kaumaha) = 37.26 N

Pae 5: 5.000 kg = (0.325 + Helu 5 4.675 Kaumaha) = 49.03 N

Pae 6: 10.000 kg = (0.325 + Helu 5 4.675 Kaumaha + Helu 6 5.000 Kaumaha) = 98.07 N

Pae 7: 12.000 kg = (0.325 + Helu 5 4.675 Kaumaha + Helu 6 5.000 + Helu 7 2.500 Kaumaha) = 122.58 N

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

ʻO ka hewa pili o ke kaumaha he ≤ 0.5%.

3. Pae Mahana: 50°C ~300°C

4. Paʻa o ka Mahana: ±0.5°C

5. Lako Mana: 220V ± 10%, 50Hz

6. Nā Kūlana o ke Kaiapuni Hana:

Mahana Ambient: 10°C a i 40°C;

Ka Haumākū Pili: 30% a i 80%;

ʻAʻohe mea ʻino i nā wahi a puni;

ʻAʻohe Hoʻoili Ea Ikaika;

ʻAʻohe haʻalulu a i ʻole ke komo ʻana o ke kahua magnetic ikaika.

7. Nā Ana o ka Mea Hana: 280 mm × 350 mm × 600 mm (Lōʻihi × Laulā ×Kiʻekiʻe)

ʻAno a me ke Kumumanaʻo Hana:

ʻO ka mea hoʻāʻo kahe kahe he ʻano mika plastik extrusion. Ma lalo o nā kūlana mahana i kuhikuhi ʻia, hoʻomehana ʻia ka hāpana e hoʻāʻo ʻia i kahi mokuʻāina heheʻe e kahi umu wela kiʻekiʻe. A laila hoʻopuka ʻia ka hāpana heheʻe ma o kahi lua liʻiliʻi o ke anawaena i kuhikuhi ʻia ma lalo o ke kaumaha o ke kaumaha i kuhikuhi ʻia. I ka hana plastik o nā ʻoihana ʻoihana a me ka noiʻi ʻana o nā ʻoihana noiʻi ʻepekema, hoʻohana pinepine ʻia ka "kahe kahe heheʻe (mass)" e hōʻike i ka wai, ka viscosity a me nā waiwai kino ʻē aʻe o nā mea polymer i ke mokuʻāina heheʻe. ʻO ka mea i kapa ʻia ʻo ka helu hoʻoheheʻe e pili ana i ke kaumaha awelika o kēlā me kēia ʻāpana o ka hāpana extruded i hoʻololi ʻia i ka nui extrusion i loko o 10 mau minuke.

Hōʻike ʻia ka mea hana o ka nui o ke kahe ʻana o ka heheʻe (mass) e MFR, me ke anakahi: grams no 10 mau minuke (g/min).

ʻO ke ʻano hana:

MFR(θ, mnom) = tref . m / t

Ma hea: θ —- mahana hoʻāʻo

Mnom— - ukana maʻamau (Kg)

m —- ka nuipaʻa awelika o ka ʻoki ʻana, g

tref —- manawa kuhikuhi (10 mau minuke), S (600s)

t ——- ka manawa o ka ʻoki ʻana, s

Laʻana:

Ua ʻoki ʻia kahi hui o nā laʻana palaki i kēlā me kēia 30 kekona, a ʻo nā hopena o ke kaumaha o kēlā me kēia ʻāpana: 0.0816 gram, 0.0862 gram, 0.0815 gram, 0.0895 gram, 0.0825 gram.

ʻO ka awelika waiwai m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (grams)

E pani i loko o ke ʻano hana: MFR = 600 × 0.0843 / 30 = 1.686 (grama no 10 mau minuke)
