Ipropylene oxide(PO) yikhompawundi yeekhemikhali eziguquguqukayo enemisebenzi emininzi yoshishino. I-China, ingumenzi obalaseleyo kunye nomthengi we-PO, ibone ukwanda kwemveliso kunye nokusetyenziswa kwale khompawundi kwiminyaka yakutshanje. Kweli nqaku, sijonga nzulu ukuba ngubani owenza ipropylene oxide eTshayina kunye nezinto eziqhuba oku kukhula.

Ukuveliswa kwe-propylene oxide e-China ngokuyinhloko kuqhutywa yimfuno yasekhaya ye-PO kunye ne-derivatives yayo. Ukukhula kuqoqosho lwaseTshayina, kunye nokwandiswa kwamashishini asezantsi afana neemoto, ulwakhiwo, kunye nokupakishwa, kukhokelele ekunyukeni kwemfuno yePO. Oku kukhuthaze abavelisi basekhaya ukuba batyale imali kwizibonelelo zemveliso ye-PO.

Abadlali abaphambili kwimarike yaseTshayina yePO babandakanya iSinopec, BASF, kunye neDuPont. Ezi nkampani ziseke amaziko emveliso emikhulu ukuhlangabezana nemfuno ekhulayo ye-PO elizweni. Ukongeza, kukho abavelisi abaninzi abancinci abathatha inxaxheba ebalulekileyo kwimarike. Aba badlali bancinci bahlala beswele itekhnoloji ephezulu kwaye bayasokola ukukhuphisana neenkampani ezinkulu kumgangatho kunye nokusebenza kakuhle kweendleko.

Ukuveliswa kwepropylene oxide eChina kukwaphenjelelwa yimigaqo-nkqubo kunye nemimiselo karhulumente. Urhulumente waseTshayina uye wakhuthaza uphuhliso lweshishini lemichiza ngokunika inkuthazo kunye nenkxaso kubavelisi basekhaya. Oku kukhuthaze iinkampani ukuba zenze utyalo-mali kuphando nophuhliso (R&D) imisebenzi yokuvelisa izinto ezintsha kunye nokuphuhlisa ubugcisa obutsha bemveliso yePO.

Ngaphezu koko, ukusondela kweTshayina kubaboneleli bezinto ezikrwada kunye neendleko eziphantsi zabasebenzi bayinike inzuzo yokhuphiswano kwimarike ye-PO yehlabathi. Uthungelwano oluluqilima lwekhonkco lonikezelo lwelizwe kunye nenkqubo yolungiselelo esebenzayo nayo idlale indima ebalulekileyo ekuxhaseni isikhundla sayo njengomvelisi ophambili wePO.

Ukuqukumbela, ukuveliswa kwe-propylene oxide yaseChina kuqhutywa yindibaniselwano yezinto ezibandakanya imfuno eqinile yasekhaya, inkxaso karhulumente, kunye neenzuzo zokukhuphisana kwizinto eziluhlaza kunye neendleko zabasebenzi. Ngoqoqosho lwaseTshayina olucetywayo ukuqhubeka lukhula ngesantya esiqinileyo, imfuno ye-PO kulindeleke ukuba ihlale iphezulu kwiminyaka ezayo. Oku kuthetha kakuhle kubavelisi be-PO belizwe, nangona kuya kufuneka bahlale besazi ngenkqubela phambili yezobuchwepheshe kwaye bathobele imithetho engqongqo karhulumente ukugcina ukhuphiswano lwabo.
