Muva nje, intengo yemikhiqizo yamakhemikhali inyukile: Kunezinhlobo eziningi kanye nezinhlobo ezinkulu. Ngo-Agasti, amanani emikhiqizo yamakhemikhali aqale ukukhuphuka. Phakathi kwentengo yemikhiqizo yamakhemikhali engu-248 esiyilandelele, imikhiqizo engu-165 inyukile ngentengo ngokukhuphuka okumaphakathi okungu-29.0%, kanti imikhiqizo engu-51 kuphela ehle ngentengo ngokwehla okumaphakathi okungu-9.2%. Phakathi kwayo, amanani e-pure MDI, i-butadiene, i-PC, i-DMF, i-styrene neminye imikhiqizo akhuphuke kakhulu.

Isidingo semikhiqizo yamakhemikhali sivame ukuba nezinkathi ezimbili eziphakeme, okungukuthi uMashi-Ephreli ngemuva koMkhosi waseNtwasahlobo kanye noSepthemba-Okthoba engxenyeni yesibili yonyaka. Idatha yomlando ye-China Chemical Product Price Index (CCPI) kusukela ngo-2012 kuya ku-2020 nayo iqinisekisa umthetho wokusebenza kwale mboni. Futhi njengalo nyaka, amanani emikhiqizo aqhubeke nokukhuphuka kusukela ngo-Agasti, futhi angene onyakeni wentshiseko enganciphi ngoNovemba, kuphela ngo-2016 nango-2017 okuqhutshwa izinguquko ohlangothini lokuhlinzeka.

Intengo kawoyela ongahluziwe idlala indima ebalulekile emananini emikhiqizo yamakhemikhali. Ngokuvamile, amanani emikhiqizo yamakhemikhali ngokuvamile ayakhuphuka futhi ehle ngokuhambisana nokushintshashintsha kwamanani kawoyela ongahluziwe. Kodwa-ke, enkambisweni yokwenyuka kwentengo yemikhiqizo yamakhemikhali, amanani kawoyela ongahluziwe ahlale eshintshashintsha, futhi amanani kawoyela ongahluziwe amanje asephansi kunamanani okuqala kuka-Agasti. Uma sibheka emuva eminyakeni eyi-9 edlule, intengo yemikhiqizo yamakhemikhali kanye nowoyela ongahluziwe yehle kakhulu izikhathi ezi-5 kuphela, kaningi esikhathini sokushaqeka okukhulu noma esiphansi, futhi amanani kawoyela ongahluziwe akhuphuke ngenkathi amanani emikhiqizo yamakhemikhali ehlala ephansi noma ephansi. Kuphela kulo nyaka lapho intengo yemikhiqizo yamakhemikhali ikhuphuka kakhulu, kuyilapho intengo kawoyela ongahluziwe ishintshashintsha. Ngaphansi kwezimo ezinjalo, ukwenyuka kwamanani emikhiqizo yamakhemikhali kuye kwandisa kakhulu inzuzo yezinkampani ezihlobene.

Izinkampani zamakhemikhali ngokuvamile zingenye yezixhumanisi ochungechungeni lwezimboni, futhi iningi lamakhasimende azo aphezulu noma aphesheya nawo ayizinkampani zamakhemikhali. Ngakho-ke, lapho intengo yomkhiqizo yebhizinisi A ikhuphuka, izindleko zebhizinisi B, okuyibhizinisi eliphansi, nazo zizokhuphuka. Ibhekene nalesi simo, inkampani B inciphisa ukukhiqizwa noma imise ukukhiqizwa ukuze inciphise ukuthengwa, noma inyuse intengo yemikhiqizo yayo ukuze ishintshe ingcindezi yezindleko ezikhuphukayo. Ngakho-ke, ukuthi intengo yemikhiqizo engezansi ingakhuphuka yini kuyisisekelo esibalulekile sokwahlulela ukusimama kokwenyuka kwentengo yemikhiqizo yamakhemikhali. Njengamanje, ezinhlotsheni eziningi zezimboni, intengo yemikhiqizo yamakhemikhali isiqalile ukusabalala kahle.

Isibonelo, intengo ye-bisphenol A inyusa intengo ye-PC, i-silicon metal inyusa intengo ye-silicon ephilayo, eqhuba intengo yamakhemikhali enjoloba neminye imikhiqizo, intengo ye-adipic acid iqhuba intengo ye-slurry ne-PA66, kanti intengo ye-MDI emsulwa ne-PTMEG iqhuba intengo ye-spandex.

Phakathi kwentengo yemikhiqizo yamakhemikhali engu-248 esiyilandelele, amanani emikhiqizo angu-116 ayesephansi kunentengo yangaphambi kobhubhane; uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule, amanani emikhiqizo angu-125 ayephansi kunesikhathi esifanayo ngonyaka odlule. Sisebenzisa intengo emaphakathi yemikhiqizo ngo-2016-2019 njengentengo emaphakathi, kanti amanani emikhiqizo angu-140 asephansi kunentengo emaphakathi. Ngesikhathi esifanayo, phakathi kokusabalala kwemikhiqizo yamakhemikhali okungu-54 esikulandelele, ukusabalala okungu-21 kusephansi kunokusabalala kwangaphambi kobhubhane; uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule, ukusabalala kwemikhiqizo okungu-22 kuphansi kunesikhathi esifanayo ngonyaka odlule. Sisebenzisa ukusabalala kwemikhiqizo okumaphakathi kuka-2016-2019 njengokusabalala kwemikhiqizo emaphakathi, kanti ukusabalala kwemikhiqizo okungu-27 kusephansi kunokusabalala kwemikhiqizo emaphakathi. Lokhu kuhambisana nemiphumela yedatha ye-PPI yonyaka nonyaka kanye nemiphumela yedatha yekota ngayinye.
