DRK208 Melt Flow Rate Tester

The DRK208 melt flow rate tester ndi chida choyezera kuchuluka kwa ma polima apulasitiki pa kutentha kwakukulu molingana ndi njira yoyesera ya GB3682-2018. Amagwiritsidwa ntchito pa polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nayiloni fluoroplastics, etc. Kuyeza kwa Sungunulani otaya mlingo wa polima pa kutentha kwambiri. Ndizoyenera kupanga ndi kufufuza m'mafakitale, mabizinesi ndi magawo ofufuza asayansi.

Zofunika Kwambiri:

1. Gawo la Extrusion:
Diameter of the discharge port: Φ2.095±0.005 mm
Kutalika kwa doko lotulutsa: 8.000± 0.005 mm
Diameter of charger silinda: Φ9.550±0.005 mm
Utali wa mbiya yolipiritsa: 160±0.1 mm
pisitoni ndodo mutu awiri: 9.475±0.005 mm
Piston ndodo mutu kutalika: 6.350±0.100mm

2. Mphamvu yoyesera yokhazikika (mlingo wachisanu ndi chitatu)
Level 1: 0.325 kg = (ndodo ya pistoni + thireyi yolemetsa + manja otsekereza kutentha + 1 thupi lolemera)
=3.187N
Msinkhu 2: 1.200 kg=(0.325+0.875 kulemera No. 2)=11.77 N
Mzere 3: 2.160 kg = (0.325 + No. 3 1.835 kulemera) = 21.18 N
mlingo 4: 3.800 kg=(0.325+No. 4 3.475 kulemera)=37.26 N
Mzere 5: 5.000 kg = (0.325 + No. 5 4.675 kulemera) = 49.03 N
Mlingo 6: 10.000 kg=(0.325+No. 5 4.675 kulemera + No. 6 5.000 kulemera)=98.07 N
mlingo 7: 12.000 kg=(0.325+No. 5 4.675 kulemera+No. 6 5.000+No. 7 2.500 kulemera)=122.58 N
Mlingo 8: 21.600 kg=(0.325+No. 2 0.875 kulemera+No. 3 1.835+No. 4
3.475+No.5 4.675+No.6 5.000+No.7 2.500+No.8 2.915 kulemera)=211.82 N
Cholakwika chachibale cha kulemera kwake ndi ≤0.5%.

3. Kutentha kosiyanasiyana:50-300 ℃
4. Kulondola kwa kutentha kosasintha:± 0.5 ℃.
5. Magetsi:220V ± 10% 50Hz
6. Malo ogwirira ntchito:kutentha kozungulira ndi 10 ℃-40 ℃; chinyezi wachibale wa chilengedwe ndi 30% -80%; palibe zowononga pozungulira, palibe mpweya wamphamvu; palibe kugwedezeka mozungulira, palibe kusokoneza kwamphamvu kwa maginito.
7. Miyeso ya kunja kwa chida: 250 × 350 × 600 = (kutalika × m'lifupi × kutalika)
Kapangidwe ndi mfundo zogwirira ntchito:
DRK208 melt flow rate tester ndi mita yotulutsa pulasitiki. Amagwiritsa ntchito ng'anjo yotentha kwambiri kuti chinthu choyezeracho chifike pamalo osungunuka pansi pa kutentha komwe kwatchulidwa. The mayeso chinthu mu chikhalidwe chosungunuka ichi ndi pansi pa mayeso extrusion kudzera dzenje laling'ono la m'mimba mwake pansi pa katundu yokoka ya kulemera analamula. Popanga pulasitiki yamabizinesi akumafakitale komanso kafukufuku wamayunitsi ofufuza asayansi, "kusungunuka (misala) kuthamanga" nthawi zambiri kumagwiritsidwa ntchito kuwonetsa mawonekedwe akuthupi a zinthu za polima mumkhalidwe wosungunuka monga fluidity ndi mamasukidwe akayendedwe. Zomwe zimatchedwa kusungunula index zimatanthawuza kulemera kwapakati pa gawo lililonse la extrudate lotembenuzidwa kukhala voliyumu ya extrusion ya mphindi 10.
Melt (mass) flow rate mita imawonetsedwa ndi MFR, gawoli ndi: magalamu/mphindi 10 (g/min), ndipo chilinganizocho chimawonetsedwa ndi: MFR (θ, mnom)
=tref .m/t
Mu chilinganizo: θ—— kuyesa kutentha
mmmm- mwadzina katundu Kg
m -- pafupifupi kulemera kwa odulidwa g
tref —— nthawi yofotokozera (10min), S (600s)
t -- kudula nthawi s
Chida ichi chimapangidwa ndi ng'anjo yowotchera komanso njira yoyendetsera kutentha ndipo imayikidwa pansi pa thupi (gawo).
Gawo lowongolera kutentha limagwiritsa ntchito mphamvu ya single-chip microcomputer ndi njira yowongolera kutentha, yomwe ili ndi mphamvu zotsutsana ndi kusokoneza, kuwongolera kutentha kwambiri, komanso kuwongolera kokhazikika. Waya wotenthetsera mu ng'anjoyo amavulazidwa pa ndodo yowotchera molingana ndi lamulo linalake kuti achepetse kutentha kuti akwaniritse zofunikira.

Kusamalitsa:
1. Soketi yamagetsi imodzi iyenera kukhala ndi dzenje loyambira ndikukhala pansi modalirika.
2. Ngati chiwonetsero chachilendo chikuwoneka pa LCD, chizimitseni choyamba, kenaka bwererani kutentha kwa mayeso mutatha kuyatsa, ndikuyamba ntchito.
3. Panthawi yogwira ntchito bwino, ngati kutentha kwa ng'anjo kuli kwakukulu kuposa 300 ° C, mapulogalamuwa amateteza, kusokoneza kutentha, ndi kutumiza alamu.
4. Ngati chochitika chachilendo chikuchitika, monga kutentha sikungathe kuyendetsedwa kapena kuwonetsedwa, ndi zina zotero, ziyenera kutsekedwa ndi kukonzedwa.
5. Poyeretsa ndodo ya pisitoni, musakolole ndi zinthu zolimba.

Zindikirani: Chifukwa cha kupita patsogolo kwaukadaulo, zambiri zidzasinthidwa popanda chidziwitso. Chogulitsacho chimagwirizana ndi chinthu chenichenicho panthawi yamtsogolo.
