I-ACR impact modifier iyi-acrylic copolymer enesakhiwo se-core-shell, edlala izindima eziningi ezibalulekile ekucutshungulweni kwepulasitiki njenge-PVC
1. Ukuthuthukiswa kokumelana nomthelela
Ngokufaka imigqa yesiliva kanye nama-shear band ngokusebenzisa i-elastomer yesendlalelo esiyinhloko, amandla omthelela ayamuncwa, okuthuthukisa kakhulu amandla omthelela womkhiqizo (ikakhulukazi ezindaweni ezishisa kakhulu); Ukwakheka kwesakhiwo segobolondo eliyinhloko kungandisa amandla omthelela ngokuphindwe izikhathi ezingaphezu kweziyisithupha futhi kugcine ukuqina okungu-90% ku--40 ℃
2. Ukuthuthukisa ukusebenza kokucubungula
Khuthaza ukwenziwa kwepulasitiki kwe-PVC, nciphisa isikhathi sokucubungula, thuthukisa ukugeleza kokuncibilika kanye nokuqina; Nciphisa isimo sokuqhekeka kokuncibilika futhi uthuthukise ikhwalithi yokukhipha amaphrofayili ayinkimbinkimbi ezingxenyeni ezihlukene
3. Ukuthuthukiswa kokusebenza okuphelele
Thuthukisa ukushelela kobuso bomkhiqizo futhi ususe amaphutha afana namehlo enhlanzi kanye nezimpawu zokugeleza; Thuthukisa ukumelana nesimo sezulu, ukumelana nokushisa, kanye nokuqina kwamakhemikhali, okulungele kakhulu imikhiqizo yangaphandle.
4. Izinzuzo ezikhethekile zohlelo lokusebenza
Ukuhambisana okuhle kakhulu ne-PVC, okuhlakazeke ngokulinganayo ukuze kugwenywe ukuhlangana; Uma kuqhathaniswa neziguquli ezifana ne-CPE, i-ACR inobubanzi bokushisa bokucubungula kanye nokusebenza kahle kokuguqulwa okuphezulu; I-ACR ecacile ingagcina ukuhanjiswa kokukhanya okungaphezu kuka-85% futhi ifanele imikhiqizo ecacile; Inani elijwayelekile lokwengeza lingu-0.5-5phr, futhi ukuxuba ngqo nama-alkaline fillers kufanele kugwenywe. Njengamanje, i-Bangtai Petrochemical ACR isibe ngesinye seziguquli ezikhethwayo zamaphrofayili e-PVC aqinile, amapayipi, kanye nama-alloy epulasitiki obunjiniyela.
5. Khetha imodeli ye-ACR efanele
Iphrofayili/Ipayipi: Kukhethwa amamodeli anesisindo sama-molecule aphezulu, anesisindo sama-molecule esingaphezu kuka-500000, okungandisa amandla okuncibilika ngaphezu kuka-40% futhi kuvimbele ngempumelelo ukuqhekeka kokuncibilika kwe-extrusion; Izingxenye ezibunjiwe ngomjovo/imikhiqizo enodonga oluncane: Kunconywa amamodeli anesisindo sama-molecule esiphansi, anesisindo sama-molecule esingu-300000 kuya ku-500000 ukuze kuncishiswe i-viscosity yokuncibilika futhi kwandiswe isivinini sokugcwalisa ngo-25% -30%; Imikhiqizo ecacile idinga ukuhlanganiswa ne-MBS (ipharamitha yokuncibilika 9.4-9.5) ukuze isetshenziswe ngokuhlanganisiwe, ngokudlulisa ukukhanya okungu->85%
