DRK208 Melt Flow Rate Tester
Iyo DRK208 melt flow rate tester chiridzwa chekuyera kuyerera kwezvivakwa zvepurasitiki mapolymer patembiricha yakakwira zvinoenderana neyeyedzo nzira yeGB3682-2018. Inoshandiswa kune polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics, etc. Kuyera kwekunyunguduka kwekuyerera kwepolymer pakupisa kukuru. Yakakodzera kugadzirwa uye kutsvagisa mumafekitori, mabhizinesi uye masainzi ekutsvagisa zvikamu.
Main Features:

Hurefu hwechiteshi chekuburitsa: 8.000±0.005 mm
Diameter ye silinda yekuchaja: Φ9.550±0.005 mm
Kureba kwedhiramu yekuchaja: 160±0.1 mm
Piston tsvimbo musoro dhayamita: 9.475±0.005 mm
Piston tsvimbo musoro kureba: 6.350±0.100mm
2. Standard test force (level sere)
Level 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
Nhamba 8: 21.600 kg=(0.325+No. 2 0.875 uremu+Nhamba. 3 1.835+No. 4
3.475+No.5 4.675+No.6 5.000+No.7 2.500+No.8 2.915 uremu)=211.82 N
Iko kukanganisa kwehuremu huremu ndeye ≤0.5%.
3. Tembiricha yakasiyana:50-300 ℃
4. Constant tembiricha kururama:±0.5℃.
5. Simba rekupa:220V±10% 50Hz
6. Mamiriro emamiriro ekushanda:tembiricha iri pakati pe10 ℃-40 ℃; hunyoro hunyoro hwenharaunda ndeye 30% -80%; hapana svikiro rinopisa rakatenderedza, hapana kutenderera kwemhepo kwakasimba; hapana vibration yakatenderedza, hapana simba remagineti kupindira.
7. Zviyero zvekunze zvechiridzwa: 250 × 350 × 600 = (kureba × upamhi × urefu)
Chimiro uye nheyo yekushanda:
DRK208 melt flow rate tester ndeye extruded plastiki 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.
Melt (mass) flow rate mita inotaridzwa neMFR, iyo unit ndeye: magiramu/10 maminetsi (g/min), uye fomula inoratidzwa 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 yenguva s
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.
Zvekungwaririra:
1. Chigadziko chemagetsi chimwechete chinofanira kuva negomba rekuisa pasi uye chakavimbika.
2. Kana chiratidziro chisina kujairika chikaonekwa paLCD, chidzime kutanga, wozogadzirisa tembiricha yekuyedza mushure mekuibatidza, uye tanga basa.
3. Panguva yekushanda kwemazuva ose, kana tembiricha yechoto inopfuura 300 ° C, software ichaidzivirira, inokanganisa kupisa, uye kutumira alarm.
4. Kana chiitiko chisina kujairika chikaitika, senge tembiricha haigone kudzorwa kana kuratidzwa, nezvimwewo, inofanira kuvharwa uye kugadziriswa.
5. Paunenge uchichenesa tsvimbo yepiston, usatsvaira nezvinhu zvakaoma.
Ongorora: Nekuda kwekufambira mberi kwetekinoroji, ruzivo rwunozoshandurwa pasina chiziviso. Chigadzirwa chacho chiri pasi pechigadzirwa chaicho munguva inotevera.
