Calcium Carbonate Biodegradable Plastic Masterbatch babban aikin masterbatch ne wanda aka ƙera don magance matsalolin robobi na gargajiya na gargajiya kamar rashin isasshen ƙarfi, juriya mara kyau, tsada mai tsada, da rashin daidaituwa na tarwatsawa na yau da kullun na calcium carbonate wanda ke haifar da m saman. Waɗannan robobi na gargajiya na gargajiya sun haɗa da samfuran PBAT/PLA da samfuran PHA. Yana mai da hankali kan ba da samfura tare da ingantaccen ƙarfi, juriya da fa'idodin tsada yayin kiyaye haɓakar halittu da aiwatar da robobin da ba za a iya jurewa ba, suna ba da mafita na musamman don kayan tebur da za a iya zubar da su, fina-finan ciyawa na noma da fakitin marufi. Yana amfani da guduro PBAT mai jituwa azaman mai ɗaukar kaya tare da ƙimar narkewa na 1.5-3.0g / 10min, yana tabbatar da dacewa sama da 96% tare da nau'ikan nau'ikan filastik na biodegradable (tsarkake PBAT, PBAT / PLA blends, PHA resins) don guje wa haɓakar calcium carbonate agglomeration ko lahani na ƙasa, yayin da yake riƙe da ƙimar raguwar 6% watanni a karkashin yanayin takin zamani).
Abubuwan da ke cikin sa sun haɗa da gyare-gyaren calcium carbonate: nano-sized activated calcium carbonate bi da tare da stearic acid, tare da girman barbashi 50-200nm da adadin adadin 40% -60%, wanda ke haɓaka modul zuwa 1800-2500MPa, yana inganta juriya ta 30% -40% kuma rage farashin -25% Abubuwan da suka dace: maleic anhydride grafted PBAT tare da ƙarin adadin 4% -8%, kiyaye ≥85% elongation a hutu; da masu gyara kayan aiki: haɗaɗɗen PE kakin zuma da resin silicone tare da ƙarin adadin 2% -5%, haɓaka ƙimar narkewa ta 10% -15%. Ta hanyar haɗuwa da tagwayen dunƙule a 120-140 ℃, daidaituwar rarrabuwar calcium carbonate ya kai ≥97% tare da saurin narkewar ruwa ≤4%.
Masterbatch ya haɗu da ingantaccen kayan haɓaka injiniyoyi da haɓaka farashi tare da daidaitawa mai ƙarfi na sarrafawa. Barga a -30 ℃-65 ℃, yana aiki a 120-165 ℃ tare da daidaitacce Bugu da kari 10% -50%, adana ≥85% elongation da saduwa GB 4806.7-2016 abinci lamba matsayin. Ya dace da PBAT/PLA calcium carbonate-reinforced tableware (rigid), calcium carbonate-cilled mulch movies (ƙasa-taki), PHA marufi pallets (daukar nauyi), da kuma yau da kullum bukatun (scratch-resistant), rage muhalli gurbatawa da kuma samar da kudin.
