Ukucubungula inkunkuma yeplastiki kwipropane - itekhnoloji yenkulungwane yama-21
Inkunkuma yeplastiki yintlungu ebuhlungu kulo naliphi na ilizwe elikwiplanethi enguMhlaba. Abanye bathi batshisa iipolymers, ngelixa abanye beziqokelela kwiindawo zokulahla inkunkuma. Kukho amazwe anobuchule bokurisayikilisha, emva kokuhlelwa okuntsonkothileyo ngohlobo lweplastiki. Isixhobo esilungileyo sokutshatyalaliswa kwenkunkuma yayibuchwephesha bepolymer granulation ukwenzela ukuveliswa okuqhubekayo kwendlela. Ilizwe ngalinye linendlela yalo yokurisayikilisha inkunkuma.
Abantu baseMelika bacebisa ukutshintsha imeko ngokuphinda kusetyenziswe iplastiki. IMassachusetts Institute of Technology yafumana indlela eyodwa. Iingcali zenzululwazi ziceba ukutshabalalisa iiplastiki zisebenzisa izinto ezicatalyst. Isiphumo kufuneka sibe yigesi yepropane. Ngaphezu koko, isivuno esiluncedo sifikelela kuma-80%. I-zeolite esekwe kwi-cobalt isetyenziswa njenge-catalyst.
Ukucubungula inkunkuma yeplastiki kwipropane - itekhnoloji yenkulungwane yama-21
Lo mbono unomdla. Ubuncinci into yokuba ukuveliswa kwepropane akuyimfuneko ukuchitha ixesha lokuhlela. Ukongezelela, kwixesha leengxaki zamandla eYurophu, le yindlela efanelekileyo yokuhlawula ukungabikho kwegesi yendalo. Isisombululo esinjalo soqoqosho siya kuvala imibuzo emininzi ngaxeshanye:
- Ukukhupha inkunkuma.
- Ukukwazi ukuqhubeka nokusebenzisa iplastiki ephantsi kwimveliso ngaphandle kokulimala kokusingqongileyo.
- Ukonga kwiinkuni. Ngokwenene, ngenxa yokuvalwa kweengxowa zeplastiki, amazwe amaninzi atshintshele ephepheni.
- Ukufumana igesi eluncedo (propane) kwicandelo lamandla.
Ngokuchasene nemvelaphi yazo zonke ezi zibonelelo, kukho enye into ebalulekileyo. Cobalt. Isinyithi esinzima sembiwa kumazwe alishumi elinesibini. Oko kukuthi, kwamanye amazwe apho kungambiwa khona, kuya kuba nexabiso elithile. Ngokwemvelo, ngokwembono yezoqoqosho, kuvela imibuzo - indlela esebenzayo ngayo indlela yokucubungula.
Ukuqwalasela ukuba kukho iidiphozithi ezinkulu ze-cobalt e-Afrika, e-China, e-Australia, eCanada naseRashiya, ukuqhutyelwa kweplastiki kwi-propane kuya kuba nomdla kuphela kumazwe adweliswe. Abanye kuya kufuneka babale ingeniso kunye neendleko ukuze bafumane imvumelwano ngalo mba.
