1 Kev Taw Qhia
Polyvinyl chloride (PVC) tau siv dav hauv kev ua neej nyob los ntawm kev tsim txiaj ntawm nws cov kev ua tau zoo, tus nqi qis, siab zog thiab siab corrosion kuj, thiab nws cov kev siv yog qhov thib ob loj tshaj plaws ntawm cov khoom yas tom qab polyethylene.Txawm li cas los xij, vim qhov ua tsis tau zoo ntawm PVC, cov khoom siv ntxiv yuav tsum tau ntxiv, qhov tseem ceeb tshaj plaws yog plasticizer.Cov yas siv hauv PVC feem ntau yog phthalate esters, thiab cov yas yas me me uas sawv cev los ntawm DOP muaj cov nyhuv plasticizing zoo thiab zoo sib xws nrog cov yas, tab sis lawv kuj muaj ntau yam tsis zoo.Lawv yuav tsiv mus nyob rau saum npoo ntawm cov khoom yas thaum lub sij hawm mus sij hawm ntev daim ntawv thov ntawm cov ntaub ntawv, muaj loj extraction nyob rau hauv tshwj xeeb ib puag ncig, thiab nws yuav ua rau tsis ua hauj lwm nyob rau hauv qhov chaw txias los yog kub kub, thiab cov deficiency no heev txo lub sij hawm siv thiab functionality ntawm cov khoom.
Los ntawm qhov kev xav ntawm ntau qhov kev ua haujlwm, kev tiv thaiv ib puag ncig thiab kev ua haujlwm ntev, peb lub tuam txhab tsim cov khoom siv polymer ntxiv, hloov qhov hnyav molecular ntawm cov khoom ntxiv los txhim kho cov kav ntev thiab kub kub tsis kam ntawm cov additives, thiab ua rau lawv sib haum nrog PVC los ntawm cov Ntxiv nrog rau kev ua haujlwm monomers txhawm rau txhim kho cov kev tsiv teb tsaws chaw thiab kev tshem tawm tsis kam ntawm cov additives.Peb tau ntxiv cov khoom siv hluavtaws ntxiv rau cov khoom siv PVC los tshawb xyuas cov txiaj ntsig ntawm cov khoom siv polymer no siv rau PVC hauv kev sib piv nrog cov khoom me me DOP.Cov kev tshawb pom tseem ceeb yog raws li hauv qab no: Hauv txoj kev tshawb no, peb xaiv emulsion polymerization los ua ke ntawm methacrylate polymers siv methyl methacrylate (MMA), styrene (st) thiab acrylonitrile (AN) ua copolymer monomers.Peb tau kawm txog kev cuam tshuam ntawm cov neeg pib sib txawv, emulsifiers, cov tshuaj tiv thaiv kub thiab qhov sib piv ntawm txhua yam ntawm cov txheej txheem polymerization hauv emulsion polymerization, thiab thaum kawg tau txais siab molecular hnyav plasticizing pab ADX-1001 thiab qis molecular hnyav plasticizing pab ADX-1002, thiab Cov khoom lag luam muaj kev sib raug zoo nrog PVC, uas tuaj yeem txo lub sijhawm plasticizing ntawm PVC resin, txo qhov kub thiab txias, ua kom cov khoom muag muag thiab siv rau kev txhaj tshuaj molding.
2 Pom zoo noj
Tus nqi ntawm cov khoom siv yas ADX-1001 yog 10 feem ntawm 100 qhov hnyav ntawm PVC cob.
3 Kev sib piv nrog Plasticizer DOP
1. Npaj cov khoom siv PVC raws li cov qauv hauv cov lus hauv qab no
Table 1
| Lub npe | Stabilizer | 4201 ib | Titanium Dioxide | Calcium Carbonate | PVC | SIB 218 | AC-6A | 660 | DOP |
| Dosage (g) | 30 | 10 | 60 | 75 | 1500 | 4.5 | 4.5 | 3 | 150 |
Rooj 2
| Lub npe | Stabilizer | 4201 ib | Titanium Dioxide | Calcium Carbonate | PVC | SIB 218 | AC-6A | 660 | AWM-1001 |
| Dosage (g) | 30 | 10 | 60 | 75 | 1500 | 4.5 | 4.5 | 3 | 150 |
Table 3
| Lub npe | Stabilizer | 4201 ib | Titanium Dioxide | Calcium Carbonate | PVC | SIB 218 | AC-6A | 660 | AW-1002 |
| Dosage (g) | 30 | 10 | 60 | 75 | 1500 | 4.5 | 4.5 | 3 | 150 |
2. Kev ua cov kauj ruam ntawm cov khoom siv PVC: Muab cov txheej txheem saum toj no cais thiab ntxiv cov khoom sib xyaw rau lub rheometer.
3. Sib piv cov txiaj ntsig ntawm ADX-1001 thiab DOP ntawm PVC ua los ntawm kev soj ntsuam cov ntaub ntawv rheological.
4. Cov khoom ua tiav ntawm PVC tom qab ntxiv cov yas sib txawv yog qhia hauv Table 4 hauv qab no.
Rooj 4
| Tsis muaj. | Plasticizing lub sij hawm (S) | Qhov sib npaug Torque (M [Nm]) | Kev sib hloov ceev (rpm) | Qhov kub thiab txias (°C) |
| DOP | 100 | 15.2 | 40 | 185 |
| AWM-1001 | 50 | 10.3 | 40 | 185 |
| AW-1002 | 75 | 19.5 Nws | 40 | 185 |
4 Kev xaus
Tom qab kev sim ua pov thawj, cov khoom siv plasticizing tsim los ntawm peb lub tuam txhab tuaj yeem txo lub sij hawm plasticization ntawm PVC resin thiab txo qhov kub ua piv rau DOP.
