Dab tsi yog qhov ntom thiab viscosity ntawm Mixed Xylene?
Xylene (CAS 1330-20-7)muaj qhov ntom ntom ntawm kwv yees li0.860-0.870 g / cm³ ntawm 20 degreethiab ib txwm kinematic viscosity ntawm kwv yees li0.6-0.8 cP (mPa·s) ntawm 20 degree, nyob ntawm qhov tseeb isomer piv ntawm cov batch. Ob lub zog no yog ib qho tseem ceeb tshaj plaws ntawm lub cev tshwj xeeb cov qauv tshuaj xyuas thaum siv cov xylene sib xyaw ua cov kuab tshuaj hauv cov xim, coatings, nplaum thiab inks, vim tias lawv ncaj qha cuam tshuam qhov hnyav npaum li cas thaum sib xyaw rau hauv cov txheej txheem resin thiab siv rau saum npoo.
Qhov ntom ntom thiab viscosity los ntawm Isomer
Txij li kev lag luam sib xyaw xylene yog ib qho kev sib xyaw ntawm o-xylene, m-xylene, p-xylene thiab feem ntau taug qab ethylbenzene, nws qhov ntom thiab viscosity zaum nyob rau hauv ntau yam uas tau hais los ntawm nws tus kheej cov khoom:
| Cheebtsam | Qhov ceev ntawm 20℃(g / cm³, approx.) | Viscosity ntawm 20℃(cP, approx.) |
|---|---|---|
| o-Xylene (CAS 95-47-6) | 0.880 | 0.81 |
| m-Xylene | 0.864 | 0.62 |
| p-Xylene | 0.861 | 0.65 |
| Ethylbenzene | 0.867 | 0.67 |
| Commercial Mixed Xylene | ~0.860–0.870 | ~0.6–0.8 |
- Nco tseg: Cov no yog cov ntawv luam tawm raws li kev siv ntau yam. Qhov tseeb qhov ceev thiab viscosity sib txawv me ntsis los ntawm cov khoom tsim tawm thiab isomer piv - ib txwm lees paub tawm tsam TDS / COA tam sim no rau qib tshwj xeeb uas koj yuav.
Vim li cas qhov ntom ntom ntom hauv txheej txheej txheej thiab logistics
Qhov ntom ntom cuam tshuam rau ob qho tib si kev tsim thiab kev txiav txim siab ntawm cov saw hlau:
- Formulation los ntawm qhov hnyav vs- Ntau cov qauv txheej yog tsim los ntawm qhov hnyav, yog li kev paub txog kev sib xyaw xylene qhov ntom yog tsim nyog los hloov qhov tseeb ntawm qhov hnyav thiab ntim ntim.
- Cov ntsiab lus ntawm cov khoom thiab VOC suav- Qhov ceev yog siv los xam cov khoom ntim thiab VOC cov ntsiab lus (g/L) hauv cov txheej txheem tiav, uas yog ib qho tseem ceeb rau kev ua raws cai hauv ntau lub khw.
- Kev npaj thauj khoom thiab ntim khoom- Vim hais tias sib xyaw xylene feem ntau yog muag thiab xa mus rau hauv nruas, IBC totes lossis ISO tso tsheb hlau luam, qhov ceev yog siv los xam cov khoom hnyav, cov nqi thauj khoom thiab cov thawv thauj khoom - nthuav dav peb pab pawg logistics hauv txhua qhov kev txiav txim ntau.
Vim li cas Viscosity Matters hauv Txheej Txheej Txheej
Viscosity txiav txim siab yooj yim npaum li cas sib xyaw xylene ntws thiab nws txo cov viscosity ntawm cov tshuaj resin:
- Thinning zog- Sib xyaw xylene cov viscosity tsawg (piv rau ntau cov resins thiab hnyav hnyav) ua rau nws muaj txiaj ntsig zoo rau kev txo cov viscosity rau lub hom phiaj tshuaj tsuag, txhuam los yog dip - daim ntawv thov ntau yam.
- Flow thiab leveling- Kev tswj kom zoo viscosity cuam tshuam zoo npaum li cas cov txheej txheej tawm tom qab thov, cuam tshuam gloss, sib xws ntawm zaj duab xis thiab muaj cov txhuam hniav lossis cov txiv kab ntxwv tev.
- Compatibility nrog cov cuab yeej siv- Cov phom phom, tshwj xeeb, yuav tsum muaj cov qauv hauv lub qhov rais viscosity; sib xyaw xylene feem ntau yog siv los coj siab - cov khoom lossis siab - viscosity resin systems rau hauv ntau yam tshuaj tsuag.
Vim hais tias viscosity thiab evaporation tus nqi ua hauj lwm ua ke los txiav txim kom qhuav tus cwj pwm, formulators feem ntau tshuaj xyuas cov xylene viscosity sib xyaw nrog nws cov evaporation profile.
Yuav ua li cas ceev thiab viscosity cuam tshuam rau lwm cov khoom sib xyaw Xylene
Qhov ntom thiab viscosity tsis ua nyob rau hauv kev sib cais - lawv cuam tshuam nrog boiling point thiab flash point los txhais tag nrho cov kuab tshuaj ua tau zoo profile ntawm tov xylene:
| Khoom | Tus nqi | Hais txog tsab xov xwm |
|---|---|---|
| Boiling Range | ~ 137-140 degree | Mixed Xylene Boiling Point |
| Flash Point (Closed Cup) | 27-32 ° C | Mixed Xylene Flash Point |
| Qhov ceev ntawm 20 degree | 0.860–0.870 g/cm³ | Zaj lus no |
| viscosity ntawm 20 degree | 0.6-0.8 hli | Zaj lus no |

FAQ: Mixed Xylene ntom thiab viscosity
Q: Vim li cas sib xyaw xylene qhov sib txawv me ntsis ntawm cov neeg muag khoom?
Qhov ceev nyob ntawm qhov tseeb isomer piv (o-, m-, p-xylene) thiab ethylbenzene cov ntsiab lus ntawm cov khoom tsim tshwj xeeb, uas tuaj yeem sib txawv me ntsis los ntawm qhov chaw tsim khoom. Nco ntsoov xyuas cov batch- tshwj xeeb COA kom pom tseeb.
Q: Puas yog sib xyaw xylene ntau dua lossis tsawg dua li dej?
Mixed xylene's viscosity (~ 0.6-0.8 cP ntawm 20 degree) yog qis dua dej (~ 1.0 cP ntawm 20 degree), txhais tau tias nws ntws yooj yim dua thiab muaj txiaj ntsig zoo ntawm kev txo cov viscosity ntawm thicker resin daws.
Q: Yuav siv qhov ceev li cas thaum xam VOC cov ntsiab lus hauv txheej?
Qhov ntom ntom hloov cov qauv ntsuas qhov hnyav-raws li cov ntsiab lus hnyav rau hauv ntim-raws li VOC cov ntsiab lus (g/L), uas yuav tsum tau ua raws li kev tshaj tawm hauv ntau txoj haujlwm tswj hwm. Formulators yuav tsum siv tus nqi ceev los ntawm kev sib xyaw xylene TDS tam sim no rau kev xam kom raug.
