Kwintsimi yeeplastiki, ukusetyenziswa kwezongezo kunye nokuzalisa kubalulekile ukuphucula iimpawu kunye nokusebenza kwemveliso yokugqibela. I-Titanium dioxide sisongezo esifumana ingqalelo eninzi. Xa yongezwa kwipolypropylene masterbatch, i-titanium dioxide inokubonelela ngoluhlu lweenzuzo, ukusuka ekuphuculeni ukuchasana kwe-UV ukuya kwisibheno esiphuculweyo sobuhle.
I-Titanium dioxide yi-titanium oxide eyenzeka ngokwemvelo eyaziwa ngokukwazi ukunika ubumhlophe, ukuqaqamba, kunye nokungafihli kwizinto ezahlukeneyo. Kwiiiplastiki, idla ngokusetyenziswa njenge-pigment ukuphumeza imibala eqaqambileyo kunye nokubonelela ngokhuseleko kwimiphumo eyingozi yemitha ye-UV. Kwi-polypropylene masterbatch, ukongezwa kwe-titanium dioxide kunokuba nefuthe elibi kumgangatho opheleleyo wemveliso yokugqibela.
Enye yezona zinto ziluncedo zokongeza i-titanium dioxide kwi-polypropylene masterbatch kukukwazi ukonyusa ukumelana ne-UV. I-Polypropylene yipolymer ethandwayo ye-thermoplastic eyaziwa ngokuguquguquka kwayo kwaye isetyenziswa kuluhlu olubanzi lwezicelo ukusuka kwipakethe ukuya kwiindawo zemoto. Nangona kunjalo, ukukhanya kwelanga ixesha elide kunokubangela ukuba izinto eziphathekayo zithotywe, okukhokelela ekuguqulweni kombala kunye nokunciphisa iimpawu zoomatshini. Ngokufaka i-titanium dioxide kwi-masterbatch, imveliso ye-polypropylene enesiphumo inokumelana ngcono nemiphumo eyingozi yemitha ye-UV, ukwandisa ubomi bayo kunye nokugcina ukubonakala kwayo.
Ukongeza, ukongezwa kwetitanium dioxideinokuphucula kakhulu iipropati zobuhle bepolypropylene masterbatch. I-pigment isebenza njenge-ejenti emhlophe, inyusa ubumhlophe kunye ne-opacity yezinto. Oku kunenzuzo ngakumbi kwizicelo apho kufuneka inkangeleko ecocekileyo, efanayo, njengokuveliswa kwezinto zabathengi, iimpahla zendlu kunye nezixhobo zonyango. Isibheno esibonakalayo esongeziweyo ngokusetyenziswa kwe-titanium dioxide inokunyusa ixabiso eliqikelelwayo leemveliso zokugqibela, zizenze zibe nomtsalane ngakumbi kubathengi nakubasebenzisi bokugqibela.
Ukongeza kwiinzuzo ezibonakalayo kunye nokukhusela, i-titanium dioxide inokuphucula ukusebenza ngokubanzi kwe-polypropylene masterbatches. Ngokusasaza ngokufanelekileyo kunye nokubonakalisa ukukhanya, i-pigments inokunceda ukunciphisa ukwakhiwa kobushushu ngaphakathi kwezinto, ngaloo ndlela inceda ukuphucula ukuzinza kwe-thermal. Oku kubaluleke kakhulu kwizicelo apho ukumelana nobushushu kuyimba ephambili, njengokwenziwa kwezixhobo zemoto kunye nezixhobo zombane.
Kubalulekile ukuqaphela ukuba ukufakwa ngempumelelo kwe-titanium dioxide kwi-polypropylene masterbatch kuxhomekeke ekusetyenzisweni komgangatho ophezulu we-masterbatch formulation. Ukusasazwa kwee-pigments kwi-polypropylene matrix kubalulekile ukuqinisekisa umbala ofanayo kunye nokusebenza kakuhle. Ke ngoko, abavelisi kufuneka bakhethe ngononophelo umthengisi we-masterbatch onobuchule kunye netekhnoloji ukufezekisa ukusasazwa kwe-titanium dioxide engaguqukiyo kwaye ethembekileyo.
Isishwankathelo, ukongeza i-titanium dioksidi kwi-polypropylene masterbatch ibonelela ngezinto ezininzi ezilungileyo, ukusuka kwi-UV ephuculweyo yokuchasa ukuya kuphuculo lobuhle kunye nokusebenza. Njengoko imfuno yemveliso yeplastiki ekumgangatho ophezulu, entle kunye nehlala ixesha elide iqhubeka nokunyuka, indima ye-titanium dioxide kwi-polypropylene masterbatches iya kubaluleka ngakumbi. Ngokusebenzisa amandla ale pigment eguquguqukayo, abavelisi banokuphucula umgangatho kunye nokuthengiswa kweemveliso zabo zepolypropylene ukuhlangabezana neemfuno eziguqukayo zamashishini ahlukeneyo kunye nabathengi.
