Abstract:Tus neeg sawv cev tiv thaiv phaj JCS-310, ib hom tshiab ntawm kev pab cuam uas yog tsim los txhim kho kev nthuav qhia ntawm phaj-tawm hauv kev ua ntawm PVC.Nws yog tsim los ntawm kev hloov kho OPE wax high-density, nrog kev sib raug zoo nrog PVC thiab tuaj yeem cuam tshuam lossis txo cov phaj tawm hauv PVC ua rau lub hauv paus tsis cuam tshuam rau nws tus kheej demolding.
Lo lus tseem ceeb:Plastic Additives, Anti Plate-out Agent, Plate-out, Processing Aid

1 Kev Taw Qhia
Polyvinyl chloride (PVC) yog dav siv nyob rau hauv lub teb ntawm lub neej vim nws cov kev ua tau zoo heev, tsis tshua muaj nqi, siab zog thiab muaj zog corrosion kuj.Nws yog hom thib ob loj tshaj plaws ntawm cov khoom yas tom qab polyethylene.Vim yog cov yam ntxwv ntawm cov khoom siv hauv PVC, stabilizers, tso cov neeg ua haujlwm, lubricants thiab lwm yam khoom siv yuav tsum tau ntxiv los tsim cov khoom nrog kev ua haujlwm zoo hauv PVC.Txawm li cas los xij, qee cov khoom ntawm PVC yuav yog phaj-tawm thiab ua raws li cov menyuam lub siab, cov ntsia hlau, cov tub ntxhais sib txuas, cov hlua los yog cov phab ntsa tuag uas maj mam tsim cov nplai, uas yog hu ua "plate-out".Tuag impression, tsis xws luag, gloss poob thiab lwm yam defects nto los yog cov zoo li tej zaum yuav tshwm sim nyob rau hauv lub extruded qhov chaw thaum muaj phaj-tawm, ua rau ib tug series ntawm cov teeb meem yog hais tias nws yog heev, xws li complexes yog tev tawm ntawm cov khoom thiab ua rau cov khoom nto paug. .Tom qab ib lub sij hawm ntawm lub sij hawm, cov yaj adheres rau cov hlau nto thiab degrades tom qab rhuab, ua rau tuag muab tshuaj txhuam thiab corrosion ntawm cov khoom, uas tas mus li ntau lawm voj voog ntawm lub tshuab ntau lawm yog shortened thiab siv sij hawm ntau zog, ntau lawm lub sij hawm, ntau lawm nqi los ntxuav. .
Nws tuaj yeem pom tau tias yuav luag tag nrho cov ntsiab lus ntawm cov qauv sib xyaw tuaj yeem yog phaj-tawm, tab sis tus nqi sib txawv.Cov yam ntxwv cuam tshuam rau cov phaj-tawm ntawm PVC ua haujlwm yog qhov nyuaj, uas yog qhov tshwm sim ntawm kev sib cuam tshuam ntau yam uas yuav hloov nrog cov txheej txheem sib txawv thiab kev siv.Txij li cov mis ntxiv hauv PVC ua yog ntau yam thiab nyuaj, nrog rau kev ua haujlwm sib txawv thiab cov khoom siv ua haujlwm, kev tshawb fawb ntawm phaj-tawm mechanism yuav nyuaj heev.Tam sim no, PVC ua kev lag luam nyob rau hauv tag nrho cov teb tau besetting los ntawm phaj-tawm.
Tus neeg sawv cev tiv thaiv phaj JCS-310 tsim los ntawm peb lub tuam txhab tau yooj yim ua ke nrog PVC vim nws cov yam ntxwv ntawm cov qauv, uas ua raws li lub hauv paus ntsiab lus ntawm kev sib raug zoo.Nws yog siv nyob rau hauv PVC ua raws li kev pab cuam, uas tsis tsuas yog muaj zoo heev demoulding, tab sis kuj yuav inhibit phaj-tawm.
2 Pom Zoo Ntxiv Tus Nqi
Nyob rau hauv txhua txhua 100 qhov chaw los ntawm qhov hnyav ntawm PVC resin, tus nqi ntawm cov tshuaj tiv thaiv phaj tawm JCS-310 yog raws li nram no: 0.5 ~ 1.5 qhov chaw los ntawm qhov hnyav ntawm anti-plate-outagent JCS-310.
3 Kev Sib Piv Ntawm Plate-Out Experim-Ents Nrog Ntau Yam Ntawm Ib-Ti Plate-Out Agent JCS-310
1.Npaj cov khoom siv PVC raws li formu-la hauv Table 1 hauv qab no.
Table 1
| Plate-out Experiments | ||||
| Raw Khoom | Kev sim 1 | Kev sim 2 | Kev sim 3 | Kev sim 4 |
| PVC | 100 | 100 | 100 | 100 |
| Calcium Carbonate | 20 | 20 | 20 | 20 |
| Stabilizer | 4 | 4 | 4 | 4 |
| CPE | 8 | 8 | 8 | 8 |
| PE WAX | 1 | 1 | 1 | 1 |
| TSO2 | 4 | 4 | 4 | 4 |
| ACR | 1 | 1 | 1 | 1 |
| Anti phaj-tawm Tus neeg sawv cev JCS-310 | 0 | 0.05 Nws | 0.10 | 0.15 |
2.Ua cov kauj ruam ntawm PVC cov khoom: muab cov qauv saum toj no, ntxiv cov khoom sib xyaw rau hauv lub thawv extruder, thiab ua tiav kev sim extrusion.
3.Cov nyhuv ntawm JCS-310 ntawm kev ua PVC tau muab piv los ntawm kev soj ntsuam cov phaj-tawm hauv qhov tuag thiab cov tsos ntawm cov khoom siv PVC.
4.Qhov kev ua haujlwm ntawm PVC nrog qhov sib txawv-nt tus nqi ntawm cov khoom siv JCS-310 yog sho-wn hauv Table 2.
Rooj 2
| Kev ua tiav | |
| Kev sim 1 | Muaj ntau lub phaj-tawm hauv qhov tuag, qhov chaw ntawm cov khoom tsis yog smooth nrog ntau khawb. |
| Kev sim 2 | Muaj me ntsis phaj-tawm hauv qhov tuag, qhov chaw ntawm cov khoom yog sm- ooth nrog ob peb khawb. |
| Kev sim 3 | Tsis muaj phaj-tawm hauv qhov tuag, qhov chaw ntawm cov khoom yog du tsis muaj khawb. |
| Kev sim 4 | Tsis muaj phaj-tawm hauv qhov tuag, qhov chaw ntawm cov khoom yog du tsis muaj khawb. |
4 Kev xaus
Cov txiaj ntsig kev sim tau lees paub tias tus neeg sawv cev tiv thaiv phaj JCS-310 tsim los ntawm peb lub tuam txhab tuaj yeem cuam tshuam cov phaj-tawm hauv PVC ua, thiab txhim kho cov khoom zoo ntawm PVC.
