Calcium carbonate yakashandiswa se inorganic filler mupurasitiki kuzadza kwemakore mazhinji.Munguva yakapfuura, calcium carbonate yaiwanzo shandiswa sekuzadza kwechinangwa chikuru chekudzikisa mari, uye yakagamuchira zvibereko zvakanaka.Mumakore achangopfuura, nekushandiswa kwakawanda mukugadzira uye nhamba huru yezviwanikwa zvekutsvaga, kuzadza huwandu hwakakura hwe calcium carbonate hakugonewo kuderedza zvakanyanya kuita kwechigadzirwa, uye kunyange kuvandudza zvakanyanya zvimwe zvinhu, senge mechanical properties, thermal properties. , nezvimwewo.
Muchiitiko chaicho chekushandisa, calcium carbonate kazhinji haina kuwedzerwa zvakananga kupurasitiki.Kuti iite kuti calcium carbonate iparadzwe zvakaenzana mupurasitiki uye iite basa mukugadzirisa mashandiro, iyo yepamusoro activation kurapwa kwe calcium carbonate inofanira kutanga yaitwa.
Zvinoenderana nemaitiro ekuumba uye kuita zvinodiwa zvechigadzirwa chepurasitiki chekupedzisira, calcium carbonate ine imwe saizi yehukuru inosarudzwa, inotanga kuvhurwa uye kurapwa neanobatsira maajenti senge coupling agent, dispersant, lubricant, nezvimwe, uyezve imwe chiyero chekutakura. resin inowedzerwa kusanganisa zvakaenzana.Sirusa extruder kuburitsa uye granulate kuti uwane calcium carbonate film masterbatch.Muzhinji, iyo calcium carbonate yemukati mu masterbatch ndeye 80wt%, iyo yakazara yemukati yezvakasiyana additives inenge 5wt%, uye inotakura resin i15wt%.
Kuwedzerwa kwecalcium carbonate kunogona kuderedza zvakanyanya mutengo wemapurasitiki
Calcium carbonate yakanyanya kuwanda uye kugadzirira kwayo kuri nyore, saka mutengo wakachipa.Mukutaura kwezvinhu zvakakosha zvepombi, mutengo we polyethylene (ine kabhoni dema) kumba nekune dzimwe nyika wakakwira, uye mutengo wakasiyana kwazvo necalcium carbonate.Iyo yakawanda calcium carbonate inowedzerwa kupurasitiki, iyo yakaderera mutengo.
Zvechokwadi, calcium carbonate haigoni kuwedzerwa nekusingaperi.Tichifunga nezvekuoma kwezvigadzirwa zvepurasitiki, huwandu hwekuzadza kwecalcium carbonate hunowanzo dzorwa mukati me50wt% (data rinopihwa nevagadziri vecalcium carbonate filler).Pakugadzirwa kwepurasitiki nesimbi-yeplastic composite pombi, mapurasitiki ndiwo makuru emidziyo, uye kudzikisa zvakanyanya mutengo wemapurasitiki pasina mubvunzo kuchaderedza zvakanyanya mutengo wekugadzira uye kubatsira mukuvandudza purofiti.
