I-calcium carbonate isetyenziswe njenge-inorganic filler ekuzalweni kweplastiki iminyaka emininzi.Kwixesha elidlulileyo, i-calcium carbonate yayisetyenziswa ngokuqhelekileyo njengento yokuzalisa eyona njongo yokunciphisa iindleko, kwaye ifumene iziphumo ezilungileyo.Kwiminyaka yakutshanje, ngokusetyenziswa ngokubanzi kwimveliso kunye nenani elikhulu leziphumo zophando, ukuzalisa isixa esikhulu se-calcium carbonate nako akunakunciphisa kakhulu ukusebenza kwemveliso, kwaye nokuphucula kakhulu ezinye iinkalo, ezifana neempawu zomatshini, iipropati zokushisa. , njl.
Kweyona nkqubo yokusetyenziswa, i-calcium carbonate ayidityaniswanga ngokuthe ngqo kwiplastiki.Ukuze wenze i-calcium carbonate ihlakazeke ngokulinganayo kwiplastiki kwaye idlale indima ekuphuculeni ukusebenza, unyango olusebenzayo lwe-calcium carbonate kufuneka luqhutywe kuqala.
Ngokwenkqubo yokubumba kunye neemfuno zentsebenzo yemveliso yokugqibela yeplastiki, i-calcium carbonate enesayizi ethile ye-particle ikhethiwe, iqale isebenze kwaye iphathwe ngama-agent ancedisayo njenge-agent yokudibanisa, i-dispersant, i-lubricant, njl., kwaye emva koko inani elithile lomphathi i-resin yongezwa ukuxuba ngokulinganayo.Screw extruder ukukhupha kunye negranulate ukufumana i-calcium carbonate film masterbatch.Ngokuqhelekileyo, umxholo we-calcium carbonate kwi-masterbatch yi-80wt%, umxholo opheleleyo wezongezo ezahlukeneyo malunga ne-5wt%, kunye ne-resin carrier carrier yi-15wt%.
Ukongezwa kwe-calcium carbonate kunokunciphisa kakhulu iindleko zeplastiki
I-calcium carbonate ininzi kakhulu kwaye ukulungiswa kwayo kulula kakhulu, ngoko ke ixabiso lincinci.Ngokubhekiselele kwizinto ezikhethekileyo zemibhobho, ixabiso le-polyethylene (nge-carbon black) ekhaya nakwamanye amazwe liphezulu, kwaye ixabiso lihluke kakhulu kwi-calcium carbonate.I-calcium carbonate eninzi yongezwa kwiplastiki, iindleko eziphantsi.
Ngokuqinisekileyo, i-calcium carbonate ayinakongezwa ngokungapheliyo.Ukuqwalasela ukuqina kweemveliso zeplastiki, inani lokuzaliswa kwe-calcium carbonate ngokuqhelekileyo lilawulwa ngaphakathi kwe-50wt% (idatha enikwe ngabavelisi be-calcium carbonate filler).Ukuveliswa kweplastiki kunye nemibhobho edibeneyo yentsimbi, iiplastiki zizona zixhobo eziphambili, kwaye ukunciphisa kakhulu iindleko zeeplastiki ngokuqinisekileyo kuya kunciphisa kakhulu iindleko zemveliso kwaye kube luncedo ekuphuculeni inzuzo.
