1 Isingeniso
Izinto zokwakha zamakhemikhali ziwuhlobo lwesine olusha lwezinto zokwakha zesimanje emva kwensimbi, izinkuni kanye nosimende, ikakhulukazi okuhlanganisa amapayipi epulasitiki, iminyango yepulasitiki namafasitela, izinto zokwakha ezingangeni manzi, izinto zokuhlobisa, njll. Impahla eluhlaza eyinhloko i-polyvinyl chloride (PVC).
I-PVC isetshenziswa kakhulu njengezinto zokwakha futhi amaphrofayili ayo epulasitiki asetshenziswa kabanzi eminyango yasendlini nangaphandle namafasitela ezakhiwo kanye nemboni yokuhlobisa, enezici ezinhle kakhulu njengokugcina ukushisa, ukubeka uphawu, ukonga amandla, ukwahlukanisa umsindo nezindleko ezimaphakathi, njll. isingeniso, umkhiqizo uthuthukiswe ngokushesha.
Kodwa-ke, amaphrofayili e-PVC aphinde abe nokubi okuthile, okufana nokuqina kwezinga lokushisa eliphansi, amandla omthelela ophansi, nobunzima bokucubungula.Ngakho-ke, izakhiwo zomthelela kanye nezakhiwo zePVC zePVC kumele zithuthukiswe.Ukwengeza izilungisi ku-PVC kungathuthukisa ngempumelelo ukuqina kwayo, kodwa izilungisi kufanele zibe nalezi zinto ezilandelayo: Izinga lokushisa eliphansi lokushintsha kwengilazi;ihambisana ngokwengxenye ne-PVC resin;ihambisana ne-viscosity ye-PVC;akukho mphumela obalulekile ezicini ezibonakalayo neziwumshini ze-PVC;izakhiwo ezinhle zezulu kanye nokwanda okuhle kokukhululwa kwesikhunta.
Iziguquli zomthelela ze-PVC ezivame ukusetshenziswa yi-chlorinated polyethylene (CPE), i-polyacrylates (ACR), i-methyl methacrylate-butadiene-styrene terpolymer (MBS), i-acrylonitrile-butadiene-styrene copolymer (ABS), i-ethylene i-vinyl acetate copolymer (EVA), i-ethylene i-vinyl acetate copolymer (EVA), (EPR), njll.
Inkampani yethu ithuthukise futhi yakhiqiza i-core-shell modifier ye-PVC JCS-817.Lesi siguquli sinomthelela omuhle ekuthuthukiseni ukwenziwa kwepulasitiki namandla omthelela we-PVC.
2 Umthamo onconyiwe
Inani lesilungisi JCS-817 lingu-6% ngezingxenye eziyi-100 zesisindo se-PVC resin.
3 Ukuqhathaniswa kokuhlolwa kokusebenza phakathi kwezilungisi ezihlukene nalesi silungisi JCS-817
1. Lungiselela isisekelo sokuhlolwa kwe-PVC ngokuya ngefomula kuThebula loku-1
Ithebula 1
| Igama | Izingxenye ngesisindo |
| 4201 | 7 |
| 660 | 2 |
| I-PV218 | 3 |
| I-AC-6A | 3 |
| I-Titanium Dioxide | 40 |
| I-PVC (S-1000) | 1000 |
| I-Organic Tin Stabilizer | 20 |
| I-calcium carbonate | 50 |
2. Ukuqhathanisa ukuhlola amandla omthelela: Hlanganisa ukwakheka okungenhla bese uxuba inhlanganisela no-6% wesisindo se-PVC nezilungisi ze-PVC ezihlukene.
Izinto ezisetshenziswayo zikalwe ngesigayo esivulekile esinamarola amabili, i-vulcanizer eyisicaba, ukwenziwa kwesampula, kanye nomshini wokuhlola wendawo yonke kanye nesihloli esilula se-beam njengoba kuboniswe kuThebula 2.
Ithebula 2
| Into | Indlela yokuhlola | Izimo zokuhlola | Iyunithi | Izinkomba zobuchwepheshe (JCS-817 6phr) | Izinkomba zobuchwepheshe (CPE 6phr) | Izinkomba zobuchwepheshe (Isampula yokuqhathanisa i-ACR 6phr) |
| Umthelela (23℃) | I-GB/T 1043 | 1A | KJ/mm2 | 9.6 | 8.4 | 9.0 |
| Umthelela (-20℃) | I-GB/T 1043 | 1A | KJ/mm2 | 3.4 | 3.0 | Lutho |
Kusukela kudatha ekuThebula 2, kungaphethwa ngokuthi amandla omthelela we-JCS-817 ku-PVC angcono kunawe-CPE ne-ACR.
3. Hlola ukuqhathanisa izakhiwo ze-rheological: Hlanganisa ukwakheka okungenhla bese wengeza u-3% wesisindo se-PVC enkomponi ngeziguquli ezihlukene ze-PVC bese uxuba.
Izakhiwo zepulasitiki ezikalwa nge-rheometer ye-Harper ziboniswa kuThebula 3.
Ithebula 3
| Cha. | Isikhathi sePlastiki (S) | I-Balance torque (M[Nm]) | Isivinini sokuzungezisa (rpm) | Hlola izinga lokushisa (℃) |
| I-JCS-817 | 55 | 15.2 | 40 | 185 |
| CPE | 70 | 10.3 | 40 | 185 |
| I-ACR | 80 | 19.5 | 40 | 185 |
Kusuka kuThebula 2, isikhathi sokwenziwa kwepulasitiki se-JCS-817 ku-PVC sincane kune-CPE ne-ACR, okungukuthi, i-JCS-817 izoholela ezimweni eziphansi zokucubungula ze-PVC.
4 Isiphetho
Amandla omthelela kanye nempahla yokwenza ipulasitiki yalo mkhiqizo i-JCS-817 ku-PVC ingcono kune-CPE ne-ACR ngemva kokuqinisekisa ukuhlolwa.
