Zithini imisebenzi ephambili ye-titanium dioxide kwimibhobho?

1, Imisebenzi engundoqo
Ukuphucula ukumelana nemozulu kunye nokumelana nokwaluphala: i-titanium dioxide (TiO2) inokuyilibazisa ngempumelelo inkqubo yokwaluphala kwemibhobho (njengemibhobho yePVC kunye nePE) kwindawo engaphandle, ithintele ukutyheli, ukuqhekeka kunye nokutshixeka komphezulu, kwaye yandise ubomi benkonzo ngokufunxa ukukhanya kwe-ultraviolet kunye nokuthintela impendulo ye-photochemical. I-Rutile titanium dioxide inamandla okukhusela i-UV aqinileyo ngenxa yonyango lokugquma (njenge-zirconia/alumina).
Ukuphucula ukugquma kunye nobumhlophe: Ipropati ephezulu ye-refractive index ivumela i-titanium dioxide ukuba isasaze ukukhanya okubonakalayo, igqume umbala osisiseko we-substrate yombhobho (njengombala otyheli okhanyayo wesiseko se-PVC), inika imveliso ubumhlophe obuphezulu, umbala ofanayo, kunye nembonakalo eqaqambileyo. Imodeli yethoni yesiseko sesigaba esiluhlaza okwesibhakabhaka inokwenza ngcono ubumhlophe obubonakalayo.
Ukuphucula ukusebenza kokucubungula kunye nozinzo: Ukufunxwa kweoyile okuphantsi (≤ 23g/100g) kunye neendlela zonyango lomphezulu wendalo (ezifana nokongeza ukukhanya kwe-TR-36) zonyusa ukusasazeka kwe-titanium dioxide kwiiplastiki ezinyibilikayo, zinciphisa ukusetyenziswa kwamandla emveliso, kwaye ziphephe iziphene ezifana neembobo kunye neempawu zokuhamba kwamanzi kumphezulu wemibhobho.
2, iimfuno zesicelo esikhethekileyo
Ukuziqhelanisa nokumelana nemozulu: Imibhobho yangaphandle kufuneka isebenzise i-rutile titanium dioxide (efana ne-SR-236, R-838), egqunywe yi-resin enokuxhathisa ukubola kwe-UV catalysis; Uhlobo lwe-titanium ebukhali luthambekele ekukhawuleziseni ukuguga kwemibhobho ngenxa yokuxhathisa kwemozulu embi.
Ithoni yombala kunye nolawulo lwesinyithi esinzima: I-titanium dioxide yesigaba esiluhlaza okwesibhakabhaka (efana ne-R-248) inokumelana nethoni etyheli yendalo yemibhobho ye-PVC kwaye iphucule ukubonakala kwayo; Ingqalelo kufuneka inikwe umxholo wesinyithi esinzima (efana ne-chromium kunye ne-lead) ye-titanium dioxide kwimibhobho enxulumene namanzi ukuze kuthintelwe ukungcolisa umgangatho wamanzi.
Ukuhambelana kokongeza: Imibhobho yePVC equlethe iziqinisi zetyuwa yelothe kufuneka ikhethwe kunye neemodeli ezifanelekileyo ukuthintela iimpembelelo ezimbi phakathi kwe-titanium dioxide kunye neziqinisi.
4, iingcebiso zokusetyenziswa
Isixa esongeziweyo: ngokuqhelekileyo yi-3% -5% yobunzima bezinto eziphathekayo, ezihlengahlengiswa ngokweemfuno zokumelana nemozulu;
Ukhuseleko lokusebenza: Kufuneka indawo yokugcina ingafumi, kwaye kufuneka kunxitywe iiglavu zokukhusela kunye neeglasi zokukhusela ngexesha lokusebenza.
Qaphela: Ukufuduka kwe-titanium dioxide kwi-heavy metal kwimibhobho enxulumene namanzi kufuneka kuqinisekiswe ngokungqongqo ukuqinisekisa ukuthotyelwa kwemigangatho yococeko.
