2. Te Kaha Whakamātautau Paerewa (E Waru Taumata)

Taumata 1: 0.325 kg = (Toka Piston + Pae Taumaha + Ringaringa Whakamarumaru + Taumaha Nama 1) = 3.187 N

Taumata 2: 1.200 kg = (0.325 + Taumaha Nama 2 0.875) = 11.77 N

Taumata 3: 2.160 kg = (0.325 + Taumaha Nama 3 1.835) = 21.18 N

Taumata 4: 3.800 kg = (0.325 + Taumaha Nama 4 3.475) = 37.26 N

Taumata 5: 5.000 kg = (0.325 + Tau 5 4.675 Taumaha) = 49.03 N

Taumata 6: 10.000 kg = (0.325 + Tau 5 4.675 Taumaha + Tau 6 5.000 Taumaha) = 98.07 N

Taumata 7: 12.000 kg = (0.325 + Nama 5 4.675 Taumaha + Nama 6 5.000 + Nama 7 2.500 Taumaha) = 122.58 N

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

Ko te hapa whanaunga o te papatipu taumaha he ≤ 0.5%.

3. Awhe Pāmahana: 50°C ~300°C

4. Te Pūmautanga o te Pāmahana: ±0.5°C

5. Pūnaha Hiko: 220V ± 10%, 50Hz

6. Ngā Āhuatanga o te Taiao Mahi:

Pāmahana Āhua: 10°C ki te 40°C;

Makuku Whakawhanaunga: 30% ki te 80%;

Kāore he mea e whakangaro ai te taiao;

Kāore he Kawenga Hau Kaha;

Kore rawa he wiri, he pokanoa rānei ki te papa aukume kaha.

7. Ngā Ahu o te Taputapu: 280 mm × 350 mm × 600 mm (Roa × Whānui ×Teitei)

Hanganga me te Mātāpono Mahi:

Ko te whakamātautau tere rere rewa he momo mita kirihou whakaputa. I raro i ngā tikanga pāmahana kua tohua, ka whakamahanahia te tauira hei whakamātautau kia rewa mā te oumu pāmahana teitei. Kātahi ka whakaputahia te tauira rewa mā roto i tētahi kōhao iti o te diameter kua tohua i raro i te kawenga o tētahi taumaha kua whakaritea. I roto i te hanga kirihou o ngā umanga ahumahi me te rangahau o ngā whare rangahau pūtaiao, ka whakamahia te "tere rere rewa (papatipu)" hei tohu i te rere, te matotoru me ētahi atu āhuatanga ā-tinana o ngā rauemi polymer i roto i te āhua rewa. Ko te mea e kiia nei ko te taupū rewa e pā ana ki te taumaha toharite o ia wāhanga o te tauira whakaputa kua hurihia ki te nui o te whakaputa i roto i te 10 meneti.

Ko te taputapu tere rere (papatipu) rewa e tohuhia ana e te MFR, ko te waeine ko: karamu ia 10 meneti (karamu/min).

Ko te tātai ko:

MFR(θ, mnom) = tref . m / t

Kei hea: θ —- pāmahana whakamātautau

Mnom— - kawenga ingoa (Kg)

m —- te taumaha toharite o te tapahi, g

tref —- wā tohutoro (10 meneti), S (600s)

t ——- te wā o te tapahi, s

Tauira:

I tapahia he rōpū tauira kirihou i ia 30 hēkona, ā, ko ngā hua o te papatipu o ia wāhanga ko: 0.0816 karamu, 0.0862 karamu, 0.0815 karamu, 0.0895 karamu, 0.0825 karamu.

Ko te uara toharite m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (karamu)

Tāpirihia ki te tātai: MFR = 600 × 0.0843 / 30 = 1.686 (karamu ia 10 meneti)
