Ukucubungula i-PVC kusiza kanjani ukuthuthukisa ukusebenza kokugcoba?

Indima yezinsiza zokucubungula i-ACR ekucutshungulweni kwe-PVC ibonakala kakhulu ekukhuthazeni ukwenziwa kwepulasitiki, ukuthuthukisa izakhiwo zokuncibilika, ukuthuthukisa ukuzinza kokucubungula, ukwenza ngcono ikhwalithi yomkhiqizo, kanye nokuthuthukisa ukuzivumelanisa nezimo kwenqubo ekhethekile.
1. Khuthaza ukwenziwa kwepulasitiki
I-ACR ixhumana namaketanga e-PVC molecular ngokusebenzisa amaqembu e-polar, inciphisa ukungqubuzana phakathi kwezinhlayiya, isheshise ukuncibilika kwepulasitiki, inciphise isikhathi sokucubungula (njenge-ACR-201, enciphisa isikhathi sokubumba ipulasitiki ngemizuzwana engama-40-60), futhi inganciphisa izinga lokushisa lokubumba ipulasitiki ngo-10-20 ℃ (kumamodeli aqukethe amaqembu e-carboxylic acid).
2. Lungiselela ukusebenza kokuncibilika
Thuthukisa amandla okuncibilika: Amaketanga amade ama-molecule akha inethiwekhi exhumene ngokomzimba, okwandisa amandla okuncibilika ngo-300% (ACR-401), okuvimbela ukuqhekeka kokuncibilika kokuphuma (njengokwenzeka kwesikhumba sikashaka);
Thuthukisa ukugeleza: nciphisa ukuncibilika kokuncibilika ngo-10-15% futhi uthuthukise ukusebenza kahle kokugcwalisa ngamanani aphezulu okusika.
3. Thuthukisa ukuzinza kokucubungula
Nqanda ukushisa kakhulu kwendawo, phakamisa izinga lokushisa lokuqala lokubola kokushisa kwe-PVC kusuka ku-190 ℃ kuya ku-210 ℃, nciphisa ukushintshashintsha kwezinga lokushisa lokuncibilika, futhi wehlise i-torque ngo-15-20% uma kuhlanganiswa nezinto zokugcoba (ACR-530).
4. Thuthukisa ikhwalithi yomkhiqizo
Ukususa amaphutha ebusweni njengamehlo enhlanzi kanye nezimpawu zokugeleza, okuthuthukisa kakhulu ukushelela (njengomhwamuko <3%, ukucwebezela okungaphezu kuka-90%); Ukuthuthukisa ukuqina komthelela (okwenyuka izikhathi ezi-5-10 kwamandla omthelela wokushisa okuphansi) kanye nokumelana nesimo sezulu.
5. Sekela izinqubo ezikhethekile
Insimu yegwebu: Thuthukisa amandla okuncibilika ukuze wenze izimbobo zegwebu zifane futhi zibe nkulu;
Umkhiqizo obonakalayo: inkomba yokukhanya ye-PVC ehambisanayo (i-ACR-Z30 haze<3%);
Insimu yezokwelapha: Nciphisa imvula (amamodeli aqukethe amaqembu e-carboxylic acid anciphisa ukukhishwa kwe-HCl ngo-60%).
Amamodeli ahlukene afanele izinqubo ezithile: I-ACR-401 (i-extrusion/rolling) ithuthukisa amandla okuncibilika, i-ACR-201 (i-injection/blow molding) ithuthukisa ukugeleza kwamanzi, i-ACR-530 ilinganisa uhlelo lokuthambisa.
