Njengomsebenzi wesibini omkhulu we-titanium dioxide, ishishini leplastiki lelona candelo likhula ngokukhawuleza kwiminyaka yakutshanje, kunye nesantya sokukhula sonyaka se-6%.Phakathi kwamabanga angaphezu kwama-500 etitanium dioxide ehlabathini, ngaphezu kwama-50 amabanga anikezelwe kwiiplastiki.Ukusetyenziswa kwe-titanium dioxide kwiimveliso zeplastiki, ukongeza ekusebenziseni amandla ayo aphezulu okufihla, amandla aphezulu achromatic kunye nezinye iimpawu ze-pigment, kunokuphucula ukuxhathisa ubushushu, ukuchasana nokukhanya kunye nokumelana nemozulu yeemveliso zeplastiki, ukuze iimveliso zeplastiki zikhuselwe. Ukukhanya kwe-UV.Ukuhlasela, ukuphucula iimpawu zomatshini kunye nombane weemveliso zeplastiki.
Ekubeni iimveliso zeplastiki zityebile kakhulu kunepeyinti nee-inki, ayifuni umthamo omkhulu woxinaniso lwebala, kwaye inamandla okufihla aphezulu kunye negunya eliqinileyo le-tinting, kwaye idosi ngokubanzi yi-3% ukuya kwi-5 kuphela.Isetyenziswe phantse kuzo zonke iiplastiki ze-thermosetting kunye ne-thermoplastic, ezifana ne-polyolefins (ikakhulukazi i-polyethylene ephantsi kakhulu), i-polystyrene, i-ABS, i-polyvinyl chloride, njl.Isigaba solwelo seplastiki sixutywe, kwaye ezinye zisetyenziswa emva kokucubungula i-titanium dioxide kwi-masterbatch.

Uhlalutyo oluthile lwesicelo se-titanium dioxide kwishishini leplastiki kunye noshishino lwe-masterbatch yombala

Uninzi lwetitanium diokside yeeplastiki zinesuntswana elincinane ngokwentelekiso.Ngokuqhelekileyo, i-particle size ye-titanium dioxide yokwaleka yi-0.2 ~ 0.4μm, ngelixa i-particle size ye-titanium dioxide yeeplastiki yi-0.15 ~ 0.3μm, ukwenzela ukuba imvelaphi eluhlaza okwesibhakabhaka inokufumaneka.Uninzi lwee-resin ezinesigaba esityheli okanye ii-resin ezilula ukuba zityheli zinempembelelo yokufihla.

I-Titanium dioxide kwiiplastiki eziqhelekileyo aziyi kunyango lomphezulu, kuba i-titanium dioxide iqatywe ngezinto ezingaphiliyo ezifana ne-alumina ye-hydrated yesiqhelo, xa ukufuma okuhambelanayo kungama-60%, amanzi alingana ne-adsorption malunga ne-1%, xa iplastiki icinezelwe kwiqondo lokushisa eliphezulu. .Ngexesha lokucubungula, ukuphuphuma kwamanzi kuya kubangela ukuba i-pores ibonakale kumphezulu weplastiki.Olu hlobo lwe-titanium dioxide ngaphandle kokugquma kwe-inorganic ngokuqhelekileyo kufuneka lwenziwe unyango lwe-organic surface (i-polyol, i-silane okanye i-siloxane), kuba i-titanium dioxide isetyenziselwa iiplastiki.Eyahlukileyo kwi-titanium dioxide yokwaleka, eyokuqala iyacutshungulwa kwaye ixutywe kwintlaka ephantsi-polarity ngamandla okucheba, kunye ne-titanium dioxide emva konyango lomphezulu we-organic inokusasazwa kakuhle phantsi kwamandla afanelekileyo okucheba oomatshini.

Ngokunyuka okuqhubekayo koluhlu lwesicelo seemveliso zeplastiki, iimveliso zeplastiki zangaphandle ezininzi, njengeengcango zeplastiki kunye neefestile, izinto zokwakha kunye nezinye iimveliso zeplastiki zangaphandle, nazo zineemfuno eziphezulu zokuxhathisa imozulu.Ukongeza ekusebenziseni i-rutile titanium dioxide, unyango olungaphezulu luyafuneka.Olu nyango lwangaphezulu alufaki i-zinc, kuphela i-silicon, i-aluminium, i-zirconium, njl.I-silicon ine-hydrophilic kunye ne-dehumidifying effect, enokuthintela ukubunjwa kwee-pores ngenxa yokuphuma kwamanzi xa iplastiki ikhutshwe kwiqondo lokushisa eliphezulu, kodwa inani lale arhente yonyango ngokuqhelekileyo ayikho kakhulu.
