KEV TSHAWB FAWB
1. Qhia Txog Qhia
No eco-zoo yasizer JD81 yog los ntawm cov khoom cog roj. Nws yog tsim los ntawm cov txheej txheem ntawm purifying linseed roj derivatives thiab saturating unsaturated bonds uas yuav cuam tshuam rau intermiscibility thiab stability. Yog li no lub teeb xim yog zoo soluble nrog PVC dua DOTP, DINP thiab muaj cov yas plasticizing, mechanical vaj tse, processability, tsuas ua tsis yog khoom, txias ua khoom thiab cov huab cua ua tsis zoo.
2. Kev tsim qauv qis
Formulation Raw khoom | A | B |
| LG PVC cob | 100 | 100 |
| JD81 | 72 | |
| DINP | 72 | |
| Ca-Zn stabilizer | 1.25 | 1.25 |
| Exxsol D70 (viscosity reducer) | 20 |
3. ua zoo thiab ua rau sim kawm
①: kev txheeb xyuas kev sib piv
Yam khoom | JD81 | DINP |
Tsos | transparency kua | transparency kua |
Density 20 ℃ (g / cm3) | 0.965-0.985 | 0.973-0.977 |
Taw tes taw (taw tes) | ≥200 | ≥219 |
txhawm rau txheeb xyuas qhov tseeb | 1.483 | 1.491 |
molecular phaus | <> | 418.6 |
Viscosity 20 ℃ (mpa.s) | 22.0 | 37.5 |
Kev ntsuam xyuas tau:
a, Viscosity ntawm JD81 yog qhov yooj yim dua thiab yooj yim mus disperse
b, Nws yog qhov yuav pab tau tsim cov hnab tes hnyav hnyav vim yog JD8's low density
c, zoo dua cov nyhuv yas vim lub cev tsis muaj molecular nyhav
D, Cov cua sov poob ntawm JD81 yuav siab dua vim tsis tshua muaj qhov taw qhia
②, Qhov sib txawv ntawm cov viscosity rau pvc gel thaum lub sij hawm (tsis muaj Exxsol D70)
Lub sijhawm / h | 0 | 4 | 8 | 12 | 16 | 20 | 24 | |
viscosity / mpa.s | A | 702 | 615 | 864 | 2405 | > 5000 | ||
B | 617 | 681 | 830 | 918 | 994 | 1148 | 1277 | |
Peb tuaj yeem nkag siab ntawm daim ntawv saum toj no, qhov qis tshaj ntawm tus qauv formula A (JD81) yog 615 map.s tom qab 4 xuab moos, thiab viscosity nce mus txog 2500+ daim ntawv qhia tom qab 16 xuab moos.the viscosity siab ntawm formula B (DINP) yog 617 daim .s nyob rau hauv thawj pib, thiab nce qeeb raws li lub sij hawm mus
③, Qhov sib txawv ntawm cov viscosity rau pvc gel los ntawm kub (tsis muaj Exxsol D70)
Kub / ℃ | Viscosity / mpa.s | |
A | B | |
45 | 702 | 617 |
48 | 1027 | 628 |
51 | 3840 | 673 |
54 | > 5000 | 813 |
57 | 994 | |
60 | 996 | |
62 | 1180 | |
66 | 1426 | |
70 | 2230 | |
75 | 3372 | |
Peb tuaj yeem to taub ntawm qhov saum toj no uas yog formula A (JD81) ntau tshaj rau qhov ntsuas kub, qhov nce mus rau 4000 mpa.s thaum ntsuas kub yog 54 ℃ Thiab qhov sib txawv ntawm kev hloov ntawm formula B (DINP) yooj yim dua los tswj
4, qhov sib txawv ntawm kev tawm ntawm viscosity by viscosity reducer
Lub mis | A | B |
Initial Viscosity η / mpa.s | 696 | 612 |
Exxsol D70 (viscosity reducer) / Phr | 20 | 20 |
Thaum kawg Viscosity η / mpa.s | 66.8 | 70.5 |
Lub voj voos (Initial viscosity) ntawm cov mis A (JD81) yog 13.7% siab dua mis B (DINP), tiam sis yuav 5% qis dua tom qab nrog viscosity reducer
5, Tshaj tawm ntawm pvc hnab looj tes
formula A (JD81) VS formula B (DINP)
Peb tuaj yeem pom los ntawm cov duab saum toj no uas cov xim formula A (JD81) yuav yog xim daj tsawg dua cov mis B (DINP).
