Zviyedzo zvinhu: Zvinoshandiswa kuona kunyunguduka kuyerera kwe polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics uye mamwe mapolymer pakupisa kwakanyanya.

Iyo XNR-400C melt flow rate tester chiridzwa chekuyeresa kuyerera kwezvivakwa zvepurasitiki mapolymer pane tembiricha yepamusoro zvinoenderana neyeyedzo nzira yeGB3682-2018. Inoshandiswa ku polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, uye nylon fluorine. Chiyero chekunyungudika kuyerera kwema polymers senge mapurasitiki pakupisa kwakanyanya. Yakakodzera kugadzirwa uye kutsvagisa mumafekitori, mabhizinesi uye masainzi ekutsvagisa zvikamu.

Piston tsvimbo musoro dhayamita: 9.475±0.005 mm
Piston tsvimbo musoro kureba: 6.350±0.100mm
2. Standard test force (level sere)
Nhamba 1: 0.325 kg = (piston tsvimbo + uremu tireyi + kupisa kupisa sleeve + 1 uremu muviri) = 3.187N
Level 2: 1.200 kg=(0.325+0.875 uremu Nha. 2)=11.77 N
Nhamba 3: 2.160 kg = (0.325 + No. 3 1.835 uremu) = 21.18 N
Nhamba 4: 3.800 kg=(0.325+No. 4 3.475 uremu)=37.26 N
Nhamba 5: 5.000 kg = (0.325 + No. 5 4.675 uremu) = 49.03 N
Level 6: 10.000 kg=(0.325+No. 5 4.675 uremu + Nha. 6 5.000 uremu)=98.07 N
Level 7: 12.000 kg=(0.325+No. 5 4.675 uremu+No. 6 5.000+No. 7 2.500 uremu)=122.58 N
Level 8: 21.600 kg=(0.325+0.875 uremu hweNhamba 2+1.835 uremu hweNo.4+3.475+No.5 4.675+No.6 5.000+No.7 2.500+No.8 2.915 uremu)=211.8 N hama kukanganisa ≤ 0.5%.
3. Tembiricha yemhando: 50-300 ℃
4. Constant tembiricha kururama: ± 0.5 ℃.
5. Simba rekushandisa: 220V±10% 50Hz
6. Mamiriro ekushanda emamiriro ezvinhu: tembiricha yepakati ndeye 10 ℃-40 ℃; hunyoro hunyoro hwenharaunda ndeye 30% -80%; hapana svikiro rinopisa rakatenderedza, hapana kutenderera kwemhepo kwakasimba; hapana kuzunguzika kwakatenderedza, hapana kupindira kwakasimba kwemagineti.

Chimiro uye nheyo yekushanda:
Iyo melt flow rate mita ndeye extruded epurasitiki mita. Inoshandisa choto chekupisa chepamusoro-soro kuita kuti chinhu chakayerwa chisvike pakunyunguduka pasi pemamiriro ekushisa akataurwa. Chinhu chekuyedzwa chiri munzvimbo iyi yakanyungudutswa chinoiswa pasi pekuyedzwa kweextrusion kuburikidza negomba diki reimwe dhayamita pasi pekuremerwa kwehuremu hwakatemwa. Mukugadzirwa kwepurasitiki kwemabhizinesi emaindasitiri uye kutsvagisa kwesainzi mayuniti ekutsvagisa, iyo "melt (mass) flow rate" inowanzo shandiswa kuratidza humiro hwezvinhu zvepolymer zvakanyungudutswa senge fluidity uye viscosity. Iyo inonzi melt index inoreva huremu hwepakati hwechikamu chimwe nechimwe che extrudate yakashandurwa kuita extrusion volume yemaminetsi gumi.
The melt (mass) flow rate mita inotaridzwa neMFR, iyo unit ndeiyi: magiramu/10 maminetsi (g/min), uye chimiro chinoratidzwa ne: MFR (θ, mnom )=tref .m/t
Mune fomula: θ—— tembiricha yekuyedza
mmmm- zita remutoro Kg
m -- chiyero chepakati chekucheka g
tref —— referensi nguva (10min), S (600s)
T —— kugura nguva s
Muenzaniso: Seti yemasampuli epurasitiki anochekwa masekonzi makumi matatu ega ega, uye mibairo yechikamu chimwe nechimwe ndeiyi: 0.0816 g, 0.0862 g, 0.0815 g, 0.0895 g, uye 0.0825 g.
Avhareji m = (0.0816+0.0862+0.0815+0.0895+0.0825)÷5=0.0843(g)
Tsiva mufomula: MFR=600×0.0843/30=1.686 (g/10 maminitsi)
Ichi chiridzwa chinoumbwa nechoto chekudziya uye tembiricha yekudzora system uye yakaiswa pazasi pemuviri (column).
Iyo tembiricha yekudzora chikamu inotora iyo single-chip microcomputer simba uye tembiricha yekudzora nzira, ine yakasimba anti-kupindira kugona, yakakwirira tembiricha kutonga, uye yakagadzikana kutonga. Iyo yekupisa waya muchoto inokuvadzwa padanda rekudziya zvinoenderana nerumwe murairo kuti kuderedze tembiricha gradient kuti isangane neyakajairwa zvinodiwa.
