Ngo-Okthoba, imakethe ye-acetone eChina yathola ukwehla kwamanani entengo ephakeme kanye namanani aphansi, ngemikhiqizo embalwa enokwanda kwenani. Ukungalingani phakathi kokuhlinzekwa kanye nokufunwa kanye nengcindezi yezindleko sekuphenduke izici eziphambili ezibangela ukuthi imakethe yehle. Ngokombono wenzuzo ephakathi kakhulu, yize imikhiqizo ephezulu yenyuka ikhuphuke kancane, inzuzo enkulu isagxilwe kakhulu emikhiqizweni esehlathini. Kulindeleke ukuthi ngoNovemba, i-Upstream Acetone chain chain idinga ukubheka ngokucophelela ukuhanjiswa kanye nesimo somdlalo, futhi imakethe ingakhombisa umkhuba wokusebenza nokusebenza okubuthakathaka.

Ngo-Okthoba, izintengo eziphakathi zanyanga zonke ze-acetone nemikhiqizo kumaketanga we-Upstream and Downstream Cains wakhombisa ukuthambekela kokuwa noma okuvuka. Ngokukhethekile, izintengo ezijwayelekile zanyanga zonke ze-acetone kanye ne-mibk zanda inyanga nenyanga, ngokwanda kwe-1.22% no-6.70%, ngokulandelana. Kodwa-ke, amanani aphakathi we-uptream pure Benzene, i-propylene, nemikhiqizo eyehlayo efana ne-bisphenol A, MMA, ne-isopropanol konke kwehle konke okuhlukahlukene. Ukungalingani phakathi kokuhlinzekwa kanye nokufunwa kanye nengcindezi yezindleko sekube yizici eziphambili ezibangela ukuncipha kwentengo.

Ngokombono wenzuzo enkulu ye-theoretical, inzuzo enkulu yenzuzo ye-uptream emsulwa i-benzene ne-Okthoba yayisondelene nomugqa wenzuzo nokulahlekelwa, okukodwa okuhle futhi okunye okulungile. Njengomkhiqizo ophakathi nendawo ecaleni lezimboni, i-Acetone isuse isikhungo sayo sentengo ngenxa yokuhlinzekwa kwezindleko nokusekelwa kwezindleko. Ngasikhathi sinye, amanani entengo ye-Phenol akhishwe phansi futhi abuye akhuphuke, okuholela ekukhuphukeni okucishe kube yi-13% inzuzo enkulu yezokwelapha ze-Phenol Ketone ngokuqhathaniswa nenyanga edlule. Kodwa-ke, emikhiqizweni ephansi, ngaphandle kwenzuzo enkulu yeBisphenol A ngezansi komugqa wenzuzo nokulahlekelwa, inzuzo ephakathi ye-MMA, i-A inyanga ngenyanga enyuselwa ngo-22.74%.

Kulindelwe ukuthi ngoNovemba, imikhiqizo ye-Acetone Chain Provent ingabonisa inkambiso yokusebenza ebuthakathaka futhi eshintshashintshayo. Ngakho-ke, kuyadingeka ukubheka eduze izinguquko ekuhlinzekeni nasekufunweni, kanye nokuholwa kwezindaba zemakethe, ngenkathi unaka izinguquko nobungako bokudluliswa kwezindleko.
