Siv rau cov khoom siv ntawm PP, PE, POM, AR, PC, ABS plastics thiab cov khoom siv yas, nws yog dav siv hauv cov khoom siv raw khoom, kev lag luam petrochemical, kev tshawb fawb tshawb fawb thiab kev soj ntsuam cov khoom muag.
Test txoj cai
Qhov ntsuas yog siv los txiav txim tus nqi ntawm extrusion ntawm molten thermoplastic resins siv lub extrusion plastometer. Tom qab lub sij hawm preheating tau teev tseg, resin yog extruded los ntawm ib tug tuag nrog ib tug ntev thiab orifice txoj kab uas hla nyob rau hauv lub preservation ntawm kub, load, thiab piston txoj hauj lwm nyob rau hauv lub chim.
Melt-mass flow rate method (MFR) feem ntau yog siv los txiav txim siab yaj ntawm cov khoom siv thermoplastic. Nws yog raws li kev ntsuas ntawm qhov loj ntawm cov khoom uas extrudes los ntawm cov tuag nyob rau lub sij hawm muab. Qhov ntsuas ntsuas yog grams ntawm cov khoom / 10 feeb (g / 10 min).
Melt-volume flow rate method (MVR) siv los txiav txim siab lub ntim ntim ntawm cov khoom siv thermoplastic. Raws li kev txiav txim siab ntawm qhov ntim ntawm cov khoom siv extruded los ntawm qhov tuag nyob rau lub sijhawm. Kev ntsuas MVR raug tshaj tawm hauv cubic centimeters/10minutes (cm³/10 min).
Cov qauv

Nta
◆ Kov npo ua kom nrawm, raug ntsuas qhov ntsuas ntsuas thiab tso saib cov ntaub ntawv.
◆ Tsis siv neeg txiav cov qauv tso cai rau kho lub sij hawm thiab lub sij hawm luv luv ntawm yaj txiav kom raug thiab rov ua dua ntawm qhov kev xeem.
◆ Tso cai rau ob txoj kev sim, qhov hnyav / MFR (Melt Flow Rate) thiab ntim / MVR (Ntshav Volume Rate).
◆ Tus neeg siv-phooj ywg kev lag luam kev tshaj lij software nrog kev sib txuas yooj yim, siv tau yooj yim thiab yooj yim los teeb tsa cov txheej txheem xeem.
