DRK208 Melt Flow Rate Tester
The DRK208 melt flow rate tester ke sesebelisoa sa ho lekanya thepa ea phallo ea polima ea polasetiki ka mocheso o phahameng ho latela mokhoa oa teko oa GB3682-2018. E sebelisoa bakeng sa polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics, joalo-joalo Tekanyo ea tekanyo ea ho qhibiliha ha polymer ka mocheso o phahameng. E loketse tlhahiso le lipatlisiso lifekthering, likhoebong le likarolong tsa lipatlisiso tsa saense.
Likarolo tsa mantlha:
1. Karolo ea Extrusion:
Bophara ba kou ea ho tsoa: Φ2.095±0.005 mm
Bolelele ba kou ea ho tsoa: 8.000±0.005 mm
Bophara ba silindara ea ho tjhaja: Φ9.550±0.005 mm
Bolelele ba barrel ea ho tjhaja: 160±0.1 mm
Piston molamu hlooho bophara: 9.475±0.005 limilimithara
Bolelele ba hlooho ea molamu oa piston: 6.350±0.100mm
2. Matla a tloaelehileng a teko (boemo ba borobeli)
Boemo ba 1: 0.325 kg = (molamu oa piston + terei ea boima + letsoho la ho kenya mocheso + 1 boima ba 'mele)
=3.187N
Boemo 2: 1.200 kg=(0.325+0.875 boima No. 2)=11.77 N
Boemo ba 3: 2.160 kg = (0.325 + No. 3 1.835 boima) = 21.18 N
Boemo 4: 3.800 kg=(0.325+No. 4 3.475 boima)=37.26 N
Boemo ba 5: 5.000 kg = (0.325 + No. 5 4.675 boima) = 49.03 N
Boemo 6: 10.000 kg=(0.325+No. 5 4.675 boima + No. 6 5.000 boima)=98.07 N
Boemo 7: 12.000 kg=(0.325+No. 5 4.675 boima+No. 6 5.000+No. 7 2.500 boima)=122.58 N
Boemo ba 8: 21.600 kg=(0.325+No. 2 0.875 boima+No. 3 1.835+No. 4
3.475+No.5 4.675+No.6 5.000+No.7 2.500+No.8 2.915 boima)=211.82 N
Phoso e amanang le boima ba 'mele ke ≤0.5%.
3. Boemo ba mocheso:50-300 ℃
4. Ho nepahala ha mocheso kamehla:±0.5℃.
5. Phepelo ea motlakase:220V±10% 50Hz
6. Maemo a tikoloho ea mosebetsi:mocheso o potolohileng ke 10 ℃-40 ℃; mongobo o lekanyelitsoeng oa tikoloho ke 30% -80%; ha ho na mokhoa o senyang o pota-potileng, ha ho na moea o matla; ha ho na vibrate ho potoloha, ha ho na tšitiso e matla ea makenete.
7. Litekanyo tsa ka ntle tsa sesebelisoa: 250×350×600=(bolelele×bophara×bophahamo)
Sebopeho le molao-motheo oa ts'ebetso:
DRK208 melt flow tester ke mitha ea polasetiki e pharalletseng. E sebelisa sebōpi sa mocheso o phahameng oa mocheso ho etsa hore ntho e lekantsoeng e fihle boemong bo qhibilihisitsoeng tlas'a boemo bo boletsoeng ba mocheso. Ntho ea teko sebakeng sena se entsoeng ka ho qhibilihisoa se kenngoa tekong ea extrusion ka lesoba le lenyenyane la bophara bo itseng tlas'a boima ba boima ba boima bo behiloeng. Tlhahisong ea polasetiki ea likhoebo tsa indasteri le lipatlisiso tsa likarolo tsa lipatlisiso tsa mahlale, "sekhahla sa ho qhibiliha (boima) se atisa ho sebelisoa ho hlalosa thepa ea 'mele ea thepa ea polymer sebakeng se qhibilihisitsoeng joalo ka fluidity le viscosity. Ho thoeng ke letšoao la ho qhibiliha le bolela boima bo tloaelehileng ba karolo e 'ngoe le e' ngoe ea extrudate e fetotsoeng ka molumo oa extrusion oa metsotso e 10.
