Hais txog yaj ntws Performance index

Dab tsi yog mob ndlwg Performance index?

Qhuav khiav tus nqi los yog nqaij ntuag Performance index, raug xa mus rau hauv cov qauv ua kua. Xa mus rau qhov loj lossis qhov ntim ntawm qhov standard tuag capillary dhau los ntawm cov yaj txhua txhua 10 feeb hauv qab qhov kub thiab txias. Qhia hauv MFR.

Nws piav qhia txog cov khoom siv ntawm cov khoom yas hauv txoj kev txhaj tshuaj molding thiab muaj ib cov nyhuv rau ntawm qhov kev lees paub thiab kev hloov ntawm cov txheej txheem hauv kev txhaj tshuaj molding. Lub pob txha muaj kev ntxhov siab feem ntau yog siv los ua ib qho kev ntsuas rau kev tswj cov thermoplastic resins thiab molding txheej txheem.

Qhov tseem ceeb ntawm kev ntsuas cov yas yaj tsom Performance index

1. Qhov siab ntawm lub yaj yog hais txog kev ua tau zoo ntawm cov yas. Cov khoom siv raw khoom feem ntau muaj lub siab yaj index, thiab qhov fluidity loj, txoj kev molding yog yooj yim, qhov nruj thiab cov cuab yeej barrier zoo; qhov feem xyuam rau cov cuab yeej ua tsis ncaj ncees, qhov chaw ntxhov siab tsis zoo rau tus kheej, cov khoom vaj tse sab nraud, thiab cov khoom nruab nrab ntawm cov tshuaj tsis haum; qhov me me ntawm kev ntsuas pib, txhuam Lub zog, qhov nyuaj, lub zog, thiab kev laus muaj kev ruaj ntseg.

2. Polyester spinning thiab txhaj tshuaj molding yog ua tiav nyob rau hauv ib lub raj ntswg. Lub viscosity ntawm yaj yog ib qho ntawm cov tseem ceeb tshaj plaws nyob rau hauv nws cov rheological thaj chaw, thiab nws tseem yog tus yuam sij rau kom cov khoom zoo.

3. Lub pob txha ua paj yog qhov kev ntsuas uas yog qhov kev ntsuas ntawm cov khoom feedstock nyob rau hauv lub hau ntswj. Qhov fluidity ntawm lub polymer yog txiav txim siab rau ib qho kev sib zog quab yuam kom raug thiab cuam tshuam txog shear thiab kub.

4. Cov khoom uas muaj siab yaj index muaj ib qho kev ntsuas me ntsis ntawm kev sib txhuam nrog cov ntsia hlau rau hauv lub extruder, thiab yog li cov zis yog tus me me. Feem ntau cov khoom siv tshuaj yaj yeeb muaj feem ntau ntau, thiab lub siab ntawm lub taub hau ntawm lub taub hau loj, uas yog qhov yuav ua rau lub network blockage.

5. Txawm tias cov khoom ntim ntawm cov khoom siv sib tw tuaj yeem ua tau raws li cov kev xav tau, yog tias kev kuaj tsis tsim nyog, lawv tsis tuaj yeem siv ua raw khoom rau kev tsim khoom.
