Oku kubizwa ngokuba ngama-pharmaceutical intermediates enyanisweni zezinye izinto zekhemikhali ekrwada okanye iimveliso zekhemikhali ezisetyenziswa kwinkqubo yokwenziwa kweziyobisi.Olu hlobo lwemveliso yeekhemikhali, aludingi kudlula ilayisenisi yokuvelisa amayeza, inokuveliswa kwisityalo sekhemikhali esiqhelekileyo, xa sifikelela kwinqanaba elithile, singasetyenziswa ekudibaneni kweziyobisi.
Abaphakathi bamayeza ngamakhonkco abalulekileyo kwikhonkco loshishino lwamayeza.
Abaphakathi bezonyango bahlulwe babaphakathi abaphambili kunye nabaphakathi abaphambili.Phakathi kwabo, ababoneleli abaphambili abaphakathi banokubonelela kuphela imveliso elula ephakathi kwaye bangaphambili kwikhonkco lezoshishino, apho uxinzelelo olukhuphisanayo kunye noxinzelelo lwexabiso lulo lukhulu.Ke ngoko, ukuguquguquka kwexabiso lezinto ezisisiseko zeekhemikhali kunempembelelo enkulu kubo.
Ngakolunye uhlangothi, ababoneleli abaphakathi abaphambili abanalo kuphela igunya eliqinileyo lokuxoxisana nababoneleli abaphambili, kodwa okona kubaluleke kakhulu, kuba benza imveliso yabaphakathi abaphambili kunye nomxholo ophezulu weteknoloji kunye nokugcina uqhagamshelwano olusondeleyo kunye neenkampani zamazwe ngamazwe, ngoko ke abachatshazelwa kancinci ngexabiso. ukuguquguquka kwemathiriyeli ekrwada.
I-Midstream ikwishishini lemichiza elungileyo.Abavelisi bamayeza aphakathi adibanisa amayeza aphakathi okanye akrwada apis kwaye athengise iimveliso ngohlobo lweemveliso zekhemikhali kumashishini axuba amayeza, athi emva koko azithengise njengamachiza emva kokusulungekiswa.
Umzi-mveliso waseTshayina wamayeza aphakathi aphuhliswe kakhulu ngo-2000.
Ngelo xesha, iinkampani ezixuba amayeza kumazwe aphuhlileyo zanikela ingqalelo ngakumbi nangakumbi kuphando lwemveliso kunye nophuhliso kunye nophuhliso lwemarike njengolona khuphiswano lungundoqo, kwaye zakhawulezisa ukudluliselwa kwamayeza aphakathi kunye nokudibanisa amachiza asebenzayo kumazwe asakhasayo aneendleko eziphantsi.Ngesi sizathu, ishishini eliphakathi kwezamayeza lifumene uphuhliso oluhle ngeli thuba.Emva kweminyaka engaphezu kweshumi yophuhliso oluzinzileyo, ngenkxaso yolawulo nolawulo jikelele lwesizwe kunye nemigaqo-nkqubo eyahlukeneyo, ilizwe lethu liye laba sisiseko esibalulekileyo semveliso ephakathi kulwahlulo lwehlabathi lwabasebenzi kushishino loxubo-mayeza.
Ukususela ngo-2016 ukuya ku-2021, ukuveliswa kwamayeza e-China kunyuke ukusuka kwi-8.1 yezigidi zeetoni, kunye nobukhulu bemarike malunga ne-168.8 yebhiliyoni ye-yuan, ukuya kwi-10.12 yezigidi zeetoni, kunye nobukhulu bemarike ye-yuan ye-2017 yezigidigidi.
