I-ACR impact modifier yi-acrylic copolymer enesakhiwo se-core-shell, edlala iindima ezibalulekileyo ekucutshungulweni kweplastiki njenge-PVC.
1. Ukuphucula ukuxhathisa impembelelo
Ngokufaka imigca yesilivere kunye neebhendi zokucheba kwi-elastomer yomaleko ongundoqo, amandla ombane ayafunxwa, nto leyo ephucula kakhulu amandla ombane wemveliso (ingakumbi kwiindawo ezinobushushu obuphantsi); Uyilo lwesakhiwo se-core-shell lunokunyusa amandla ombane we-impact ngaphezu kwamaxesha ama-6 kwaye lugcine ukuqina kwe-90% kwi--40 ℃.
2. Ukuphucula ukusebenza kweenkqubo
Khuthaza ukwenziwa kweplastiki yePVC, nciphisa ixesha lokucubungula, phucula ukuhamba kwamanzi kunye nozinzo lokunyibilika; Nciphisa imeko yokuqhekeka kwamanzi anyibilikayo kwaye uphucule umgangatho wokukhupha iiprofayili ezintsonkothileyo zecandelo elinqamlezileyo
3. Uphuculo olupheleleyo lokusebenza
Ukuphucula ukugudiswa komphezulu wemveliso kwaye kususe iziphene ezifana namehlo eentlanzi kunye neempawu zokuhamba kwamanzi; Ukuphucula ukumelana nemozulu, ukumelana nobushushu, kunye nozinzo lweekhemikhali, ngakumbi ezifanelekileyo kwiimveliso zangaphandle.
4. Iingenelo zesicelo esikhethekileyo
Ukuhambelana okuhle kakhulu ne-PVC, isasazwe ngokulinganayo ukuze kuthintelwe ukuhlangana; Xa kuthelekiswa nezilungisi ezifana ne-CPE, i-ACR inomgangatho obanzi wobushushu bokucubungula kunye nokusebenza kakuhle kokuguqula; I-ACR ecacileyo inokugcina ukuhanjiswa kokukhanya okungaphezulu kwe-85% kwaye ifanelekile kwiimveliso ezibonakalayo; Isixa esiqhelekileyo sokongeza yi-0.5-5phr, kwaye ukuxuba ngokuthe ngqo nezizalisi ze-alkaline kufuneka kuthintelwe. Okwangoku, i-Bangtai Petrochemical ACR ibe yenye yezilungisi ezikhethwayo kwiiprofayili ze-PVC eziqinileyo, iipayipi, kunye nee-alloys zeplastiki zobunjineli.
5. Khetha imodeli ye-ACR efanelekileyo
Iprofayili/Ipayipi: Iimodeli ezinobunzima obukhulu beemolekyuli ziyathandwa, ezinobunzima beemolekyuli obungaphezulu kwe-500000, ezinokunyusa amandla okunyibilika ngaphezulu kwe-40% kwaye zithintele ngempumelelo ukwaphuka kokunyibilika kwe-extrusion; Iimveliso ezibunjiweyo ngenaliti/iimveliso eziludonga oluncinci: Iimodeli ezinobunzima beemolekyuli eziphantsi ziyacetyiswa, ezinobunzima beemolekyuli obuyi-300000 ukuya kwi-5000000 ukunciphisa i-melt viscosity kunye nokunyusa isantya sokuzalisa nge-25% -30%; Iimveliso ezicacileyo kufuneka zidityaniswe ne-MBS (ipharamitha yokunyibilika 9.4-9.5) yokusetyenziswa okuhlanganisiweyo, kunye nokuhanjiswa kokukhanya okungaphezulu kwe-85%
