YYP-400E Melt Flow Indexer (MFR)

Kufotokozera Kwachidule:

Mapulogalamu:

Choyesera kuchuluka kwa madzi osungunuka cha YYP-400E ndi chida chodziwira momwe ma polima apulasitiki amagwirira ntchito kutentha kwambiri motsatira njira yoyesera yomwe yafotokozedwa mu GB3682-2018. Chimagwiritsidwa ntchito poyesa kuchuluka kwa madzi osungunuka a ma polima monga polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nayiloni, ndi fluoroplastics kutentha kwambiri. Chimagwiritsidwa ntchito popanga ndi kufufuza m'mafakitale, m'mabizinesi ndi m'mabungwe ofufuza zasayansi.

Magawo akuluakulu aukadaulo:

1. Gawo lotulutsa madzi:

M'mimba mwake wa doko lotulutsa mphamvu: Φ2.095±0.005 mm

Kutalika kwa doko lotulutsira: 8.000±0.007 mamilimita

M'mimba mwake mwa silinda yonyamula katundu: Φ9.550±0.007 mm

Kutalika kwa silinda yonyamula katundu: 152±0.1 mm

M'mimba mwake wa mutu wa ndodo ya pistoni: 9.474±0.007 mm

Utali wa mutu wa ndodo ya pistoni: 6.350±0.100 mm

2. Mphamvu Yoyesera Yokhazikika (Magawo Asanu ndi Atatu)

Gawo 1: 0.325 kg = (Ndodo ya Pistoni + Chidebe Choyezera + Chikwama Choteteza + Kulemera Kwa Nambala 1) = 3.187 N

Gawo 2: 1.200 kg = (0.325 + Nambala 2 0.875 Kulemera) = 11.77 N

Gawo 3: 2.160 kg = (0.325 + Nambala 3 1.835 Kulemera) = 21.18 N

Gawo 4: 3.800 kg = (0.325 + Nambala 4 3.475 Kulemera) = 37.26 N

Mulingo 5: 5.000 kg = (0.325 + Nambala 5 4.675 Kulemera) = 49.03 N

Gawo 6: 10.000 kg = (0.325 + Nambala 5 4.675 Kulemera + Nambala 6 5.000 Kulemera) = 98.07 N

Mulingo 7: 12.000 kg = (0.325 + Nambala 5 4.675 Kulemera + Nambala 6 5.000 + Nambala 7 2.500 Kulemera) = 122.58 N

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

Cholakwika cha kulemera kwa thupi ndi ≤ 0.5%.

3. Kutentha: 50°C ~300°C

4. Kukhazikika kwa Kutentha: ± 0.5°C

5. Mphamvu Yoperekera Mphamvu: 220V ± 10%, 50Hz

6. Mikhalidwe Yogwirira Ntchito:

Kutentha kwa Malo: 10°C mpaka 40°C;

Chinyezi: 30% mpaka 80%;

Palibe Chophimba Chowononga Pamalo Ozungulira;

Palibe Mpweya Wamphamvu Wozungulira;

Yopanda Kugwedezeka kapena Kusokonezedwa ndi Mphamvu ya Magnetic Field.

7. Miyeso ya Chida: 280 mm × 350 mm × 600 mm (Kutalika × M'lifupi ×Kutalika)

Choyesera kuchuluka kwa madzi osungunuka ndi mtundu wa choyezera pulasitiki chotulutsa madzi. Pansi pa mikhalidwe yodziwika bwino ya kutentha, chitsanzo chomwe chiyenera kuyesedwa chimatenthedwa mpaka kusungunuka ndi ng'anjo yotentha kwambiri. Kenako chitsanzo chosungunuka chimatulutsidwa kudzera mu dzenje laling'ono la mainchesi odziwika pansi pa katundu wolemera wovomerezeka. Pakupanga pulasitiki kwa mabizinesi amafakitale ndi kafukufuku wa mabungwe ofufuza asayansi, "kusungunuka (kuchuluka) kwa madzi osungunuka" nthawi zambiri kumagwiritsidwa ntchito kuyimira kusinthasintha, kukhuthala ndi zinthu zina zakuthupi za zinthu za polima zomwe zili mu mkhalidwe wosungunuka. Chomwe chimatchedwa kusungunuka kwa madzi chimatanthauza kulemera kwapakati pa gawo lililonse la chitsanzo chotulutsidwacho chomwe chasinthidwa kukhala kuchuluka kwa madzi otulutsidwa mu mphindi 10.

Chida choyezera kuchuluka kwa madzi chomwe chimasungunuka (misa) chimawonetsedwa ndi MFR, pomwe gawoli ndi: magalamu pa mphindi 10 (g/min).

Fomula yake ndi iyi:

MFR(θ, mnom) = tref . m/t

Kumene: θ —- kutentha koyesera

Mnom— - katundu wodziwika (Kg)

m —- kulemera kwapakati kwa chodulidwacho, g

tref —- nthawi yowunikira (mphindi 10), S (masekondi 600)

t ——- nthawi yomaliza, s

Chitsanzo:

Gulu la zitsanzo za pulasitiki linadulidwa masekondi 30 aliwonse, ndipo zotsatira za kulemera kwa gawo lililonse zinali: magalamu 0.0816, magalamu 0.0862, magalamu 0.0815, magalamu 0.0895, magalamu 0.0825.

Mtengo wapakati m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (magalamu)

Lowetsani mu fomula iyi: MFR = 600 × 0.0843 / 30 = 1.686 (magalamu pa mphindi 10)
