ACR-401, monga chithandizo chopangira PVC, ili ndi kusiyana kwakukulu pa malo ogwirira ntchito, kapangidwe ka mamolekyulu, ndi zochitika zogwiritsidwa ntchito. Kuyerekeza kwake ndi motere:
1. Kusiyana kwa malo ogwirira ntchito
ACR-401: Yopangidwa makamaka kuti iwonjezere kusungunuka, imapanga mfundo zolumikizirana kudzera mu kapangidwe ka chipolopolo chapakati (chipolopolo cholimba/chofewa), zomwe zimawonjezera mphamvu yosungunuka ndi 300%, makamaka yoyenera zinthu zopangidwa ndi thovu (monga ma board a thovu).
ACR-201: Kuyang'ana kwambiri pa kulimbikitsa kupangidwa kwa pulasitiki, kuchepetsa nthawi yosungunuka ya PVC ndi masekondi 40-60, yoyenera kugwiritsidwa ntchito pokonza zinthu monga mapaipi olimba ndi ma profiles.
ACR-530: Kulinganiza mafuta ndi pulasitiki, kulumikiza magulu a stearic acid kungachepetse mphamvu ndi 15-20% ndikuthetsa vuto la mvula ya mutu wa nkhungu.
2. Makhalidwe a kapangidwe ka maselo
ACR-401: Kugwiritsa ntchito kapangidwe ka core-shell ka methyl methacrylate (MMA) ndi acrylic ester copolymer, yokhala ndi hard core yomwe imapereka mfundo zolumikizirana komanso chipolopolo chofewa chomwe chimawonjezera kusinthasintha kwa kusungunuka.
Zowonjezera za MBS: zokhala ndi styrene butadiene ngati core ndi methyl methacrylate ngati chipolopolo, zomwe zimayang'ana kwambiri pakuwonekera bwino komanso kukana kukhudzidwa, koma zokhala ndi kukana koyipa kwa nyengo.
Zowonjezera za mtundu wa CPE: Kapangidwe ka polyethylene yopangidwa ndi chlorine, komwe kumawonjezera kulimba kudzera mu pulasitiki, koma kumatha kuchepetsa mphamvu yosungunuka mosavuta.
3. Kusiyana kwa magawo aukadaulo
Kukhuthala kwa mkati: ACR-401 ndi 2.0-5.0, yokwera kuposa ACR-201 (2.0-3.0), yomwe ikuwonetsa kulemera kwake kwakukulu kwa mamolekyulu.
Kuchuluka kowonjezera: ACR-401 mu zinthu za thovu imafuna 1.5-3phr, pomwe ACR-201 yonse imafuna 0.5-2phr yokha.
