1 Isingeniso
I-Polyvinyl chloride (PVC) isetshenziswe kakhulu emkhakheni wezempilo ngenxa yokusebenza kwayo okuhle kakhulu, intengo ephansi, amandla aphezulu kanye nokumelana nokugqwala okuphezulu, futhi ukusetshenziswa kwayo kuyisigaba sesibili esikhulu semikhiqizo yepulasitiki ngemuva kwe-polyethylene.Kodwa-ke, ngenxa yokungahambi kahle kwe-PVC, izithasiselo zidinga ukungezwa, okubaluleke kakhulu okuyi-plasticizer.Ama-plasticizer asetshenziswa ku-PVC ikakhulukazi ama-phthalate esters, futhi ama-plasticizers amancane e-molecule amelwe i-DOP anomphumela omuhle kakhulu we-plasticizing kanye nokuhambisana okuhle namapulasitiki, kodwa futhi aneziphambeko eziningi.Bazothuthela phezu kwemikhiqizo yepulasitiki ngesikhathi sokusetshenziswa kwesikhathi eside kwezinto, babe nesizinda esibucayi ezindaweni ezikhethekile, futhi bathambekele ekuhlulekeni ezindaweni ezibandayo noma ezishisayo, futhi lokhu kusilela kunciphisa kakhulu isikhathi sokusebenzisa nokusebenza kwemikhiqizo.
Ngokombono wokusebenza okuningi, ukuvikelwa kwemvelo nokuqina, inkampani yethu iklama uchungechunge lwezithako ze-polymer, ishintsha isisindo samangqamuzana ezithasiselo ukuze kuthuthukiswe ukuqina nokumelana nokushisa okuphezulu kwezithasiselo, futhi izenze zihambisane kakhulu ne-PVC ngokusebenzisa ukungezwa kwama-monomers asebenzayo ukuthuthukisa ukumelana nokufuduka kanye nokumelana nokukhipha kwezithasiselo.Sengeze isengezo esihlanganisiwe ezintweni ze-PVC ukuze siphenye umphumela wokucubungula walesi sengezo se-polymer esisetshenziswa ku-PVC uma siqhathaniswa ne-molecule encane ye-DOP.Okutholakele okuyinhloko kungokulandelayo: Kulolu cwaningo, sikhethe i-emulsion polymerization ukuze sihlanganise uchungechunge lwama-polymers e-methacrylate kusetshenziswa i-methyl methacrylate (MMA), i-styrene (st) ne-acrylonitrile (AN) njenge-copolymer monomers.Sifunde umthelela wabaqalisi abahlukene, ama-emulsifiers, izinga lokushisa lokuphendula kanye nesilinganiso sengxenye ngayinye enqubweni ye-polymerization ku-emulsion polymerization, futhi ekugcineni sathola izinsiza eziphakeme zamangqamuzana ze-plasticizing ADX-1001 kanye nezinsiza eziphansi ze-plasticizing aid ADX-1002, kanye imikhiqizo inokuhambisana okuhle ne-PVC, enganciphisa ngempumelelo isikhathi se-plasticizing ye-PVC resin, ukunciphisa izinga lokushisa lokucubungula, ukwenza imikhiqizo ithambe futhi isebenze ekubumbeni umjovo.
2 Umthamo onconyiwe
Inani lezinsiza ze-plasticizing ADX-1001 yizingxenye eziyi-10 ngezingxenye eziyi-100 zesisindo se-PVC resin.
3 Ukusebenza Ukuqhathanisa NePlasticizer DOP
1. Lungiselela imikhiqizo ye-PVC ngokuya ngefomula kuthebula elilandelayo
Ithebula 1
| Igama | Isiqinisi | 4201 | I-Titanium Dioxide | I-calcium carbonate | I-PVC | I-PV218 | I-AC-6A | 660 | DOP |
| Umthamo (g) | 30 | 10 | 60 | 75 | 1500 | 4.5 | 4.5 | 3 | 150 |
Ithebula 2
| Igama | Isiqinisi | 4201 | I-Titanium Dioxide | I-calcium carbonate | I-PVC | I-PV218 | I-AC-6A | 660 | I-ADX-1001 |
| Umthamo (g) | 30 | 10 | 60 | 75 | 1500 | 4.5 | 4.5 | 3 | 150 |
Ithebula 3
| Igama | Isiqinisi | 4201 | I-Titanium Dioxide | I-calcium carbonate | I-PVC | I-PV218 | I-AC-6A | 660 | I-ADX-1002 |
| Umthamo (g) | 30 | 10 | 60 | 75 | 1500 | 4.5 | 4.5 | 3 | 150 |
2. Izinyathelo zokucubungula imikhiqizo ye-PVC: Hlanganisa ukwakheka okungenhla ngokuhlukana bese wengeza inhlanganisela ku-rheometer.
3. Qhathanisa umphumela we-ADX-1001 kanye ne-DOP ekucutshungulweni kwe-PVC ngokubheka idatha ye-rheological.
4. Izici zokucubungula ze-PVC ngemva kokwengeza ama-plasticizers ahlukene aboniswa kuThebula lesi-4 ngezansi.
Ithebula 4
| Cha. | Isikhathi Sokwenza Plasticizing (S) | I-Balance Torque (M[Nm]) | Isivinini Sokuzungezisa (rpm) | Izinga lokushisa (°C) |
| DOP | 100 | 15.2 | 40 | 185 |
| I-ADX-1001 | 50 | 10.3 | 40 | 185 |
| I-ADX-1002 | 75 | 19.5 | 40 | 185 |
4 Isiphetho
Ngemuva kokuqinisekiswa kokuhlolwa, izinsiza ze-plasticizing ezithuthukiswe inkampani yethu zingafinyeza ngempumelelo isikhathi seplastiki ye-PVC resin futhi zehlise izinga lokushisa lokucubungula uma liqhathaniswa ne-DOP.
