Utshintsho olutsha kwiPateni yoRhwebo lwaNgaphandle lweTitanium Dioxide: Ukunyuka kweeMarike eziKhulayo kunye nokuHlanganisa iiMarike zeMveli

Kutshanje, i-titanium dioxide ibonakalise iimpawu ezintsha zepateni kwinqanaba lorhwebo lwamazwe ngamazwe. Kwiimarike ezikhulayo, amazwe afana neIndiya neBrazil abone uphuhliso olukhawulezayo lwemizi-mveliso, kwaye imfuno ye-titanium dioxide inyuke kakhulu. Amashishini okwakha neemoto eIndiya aphuhla ngokukhawuleza, eqhuba ukuchuma kweshishini lokugquma, ngaloo ndlela enyusa umthamo wokungenisa we-titanium dioxide nge-30% kwiinyanga ezintandathu ezidlulileyo. Abathengisi abaninzi be-titanium dioxide bamazwe ngamazwe bajike ingqalelo yabo kwimarike yaseIndiya kwaye bahlangabezana neemfuno zemarike ngokusebenzisana nabasasazi basekuhlaleni okanye ukuseka iziseko zemveliso. Kwiimarike zemveli zaseYurophu naseMelika, nangona sele kukho ishishini le-titanium dioxide elivuthiweyo, ngenxa yeendleko eziphezulu zemveliso zasekhaya kunye nokulungiswa kwamandla kwamanye amashishini, isixa esikhulu se-titanium dioxide kusafuneka singeniswe kwimarike yamazwe ngamazwe. Amanye amashishini amakhulu okuvelisa iplastiki eYurophu aseke ubudlelwane bexesha elide nobuzinzileyo bokubonelela nabavelisi be-titanium dioxide eAsia ukuze kuncitshiswe iindleko kwaye kufumaneke iimveliso ezikumgangatho ophezulu. Umzekelo, emva kokuba ishishini lokuvelisa i-titanium dioxide eTshayina liphumelele isiqinisekiso somgangatho esingqongqo seManyano yaseYurophu, langena ngempumelelo kwiikhonkco zokubonelela zamashishini amaninzi eplastiki aziwayo eYurophu, kwaye umthamo walo wokuthumela ngaphandle uye wanda unyaka nonyaka. Ukongeza, ngokuphuculwa kolwazi lwendalo jikelele, i-titanium dioxide eluhlaza neyongameleyo ikhuphisana ngakumbi kwimarike yorhwebo lwangaphandle. Iimveliso ze-titanium dioxide ezinokusetyenziswa kwamandla aphantsi kunye nongcoliseko oluphantsi oluveliswa ziinkqubo ezintsha azifumaneki kwimarike yamazwe ngamazwe. Oku akukhuthazi nje kuphela amashishini emveliso ukuba andise utyalo-mali kuphando nophuhliso lwetekhnoloji yokukhusela okusingqongileyo, kodwa kukwakhuthaza lonke ishishini lorhwebo lwangaphandle lwe-titanium dioxide ukuba liphuhlise kwicala eliluhlaza nelizinzileyo.
