M'munda wamapulasitiki, kugwiritsa ntchito zowonjezera ndi zodzaza ndikofunikira kuti pakhale mawonekedwe ndi magwiridwe antchito a chinthu chomaliza. Titanium dioxide ndi chowonjezera chomwe chikupeza chidwi kwambiri. Mukawonjezeredwapolypropylene masterbatch, titaniyamu woipa angapereke ubwino wambiri, kuchokera ku mphamvu yolimbana ndi UV mpaka kukongola kokongola.
Titanium dioxide ndi titaniyamu oxide yomwe imapezeka mwachilengedwe yomwe imadziwika ndi kuthekera kwake kopatsa kuyera, kuwala, ndi kusawoneka kuzinthu zosiyanasiyana. Mumapulasitiki, nthawi zambiri amagwiritsidwa ntchito ngati pigment kuti apange mitundu yowoneka bwino komanso kuteteza ku zotsatira zoyipa za cheza cha UV. Kwa polypropylene masterbatch, kuwonjezera kwa titaniyamu woipa kumatha kukhudza kwambiri mtundu wonse wa chinthu chomaliza.
Ubwino umodzi wowonjezera wowonjezera titaniyamu ku polypropylene masterbatch ndikutha kwake kukulitsa kukana kwa UV. Polypropylene ndi polima lodziwika bwino la thermoplastic lomwe limadziwika ndi kusinthasintha kwake ndipo limagwiritsidwa ntchito pazinthu zosiyanasiyana kuyambira pakupakira kupita kuzinthu zamagalimoto. Komabe, kuyang'ana padzuwa kwa nthawi yayitali kungapangitse kuti zinthuzo ziwonongeke, zomwe zimapangitsa kuti zisinthe komanso kuchepetsa mphamvu zamakina. Pophatikiza titaniyamu woipa mu masterbatch, chopangidwa ndi polypropylene chimatha kukana kuwononga kwa radiation ya UV, kukulitsa moyo wake ndikusunga mawonekedwe ake.
Komanso, kuwonjezera patitaniyamu dioxideimatha kusintha kwambiri zokongoletsa za polypropylene masterbatch. Pigment imagwira ntchito ngati yoyera, ndikuwonjezera kuyera komanso kusawoneka bwino kwa zinthuzo. Izi ndizopindulitsa makamaka pakugwiritsa ntchito komwe kumafunikira mawonekedwe osawoneka bwino, monga kupanga zinthu zogula, katundu wapakhomo ndi zida zamankhwala. Kuwoneka kowonjezereka kogwiritsa ntchito titanium dioxide kumatha kukulitsa mtengo wazinthu zomaliza, kuzipangitsa kukhala zokopa kwa ogula ndi ogwiritsa ntchito.
Kuphatikiza pa zabwino zowoneka ndi zoteteza, titaniyamu woipa amatha kupititsa patsogolo magwiridwe antchito a polypropylene masterbatches. Mwa kufalitsa bwino komanso kuwunikira kuwala, ma pigment angathandize kuchepetsa kutentha mkati mwa zinthuzo, motero zimathandiza kuti kutentha kukhale bata. Izi ndizofunikira makamaka pamapulogalamu omwe kukana kutentha ndi chinthu chofunikira kwambiri, monga kupanga zida zamagalimoto ndi zida zamagetsi.
Ndikofunika kuzindikira kuti kuphatikizika bwino kwa titanium dioxide mu polypropylene masterbatch kumadalira kugwiritsa ntchito kapangidwe kapamwamba ka masterbatch. Kubalalika kwa pigment mu polypropylene matrix ndikofunikira kuti zitsimikizire mtundu wofananira komanso magwiridwe antchito abwino. Chifukwa chake, opanga ayenera kusankha mosamala wopereka masterbatch ndi ukatswiri ndi ukadaulo kuti akwaniritse kupezeka kosasinthika komanso kodalirika kwa titaniyamu dioxide.
Mwachidule, kuwonjezera titanium dioxide ku polypropylene masterbatch kumapereka maubwino ambiri, kuyambira kulimbitsa kukana kwa UV mpaka kukongola ndi magwiridwe antchito. Pomwe kufunikira kwa zinthu zapulasitiki zapamwamba, zokongola komanso zolimba zikupitilira kukwera, gawo la titanium dioxide mu polypropylene masterbatches likhala lofunikira kwambiri. Pogwiritsa ntchito kuthekera kwa pigment yosunthikayi, opanga amatha kukonza bwino komanso kugulitsa zinthu zawo za polypropylene kuti akwaniritse zosowa zamakampani ndi ogula osiyanasiyana.
