Ngaphambi nasemva kweDragon Boat Festival, imakethi yepropylene oxide yasekhaya ibonakalise uluhlu oluncinci lokuguquguquka, emva kokunyuka okuncinci kwesitokhwe ngaphambi komnyhadala, imakethi yazinza, uxinzelelo lwehla emva komnyhadala, kodwa ngenxa yokuhla kwexabiso, ezinye zeenkqubo zifikelele kumgca weendleko kufutshane nemakethi efanelekileyo yenkxaso, kwaye kutshanje zibonise ukuvalwa, kodwa ingqiqo yokusebenza kwemakethi elandelayo kulindeleke ukuba ibonelele kwaye ifune, iindleko zongezelelwe, emva kokungavisisani, kusalindeleke ukuba kube buthathaka.

一. Icala lokubonelela lizinzile kwaye imakethi enyukayo ikhululekile kancinci

Phakathi kuJuni, xa kuqalwa ukusebenza kwezixhobo zesigaba soku-1 zeZhenhai, izixhobo zeJiahong eziNtsha, iQixiang Tengda izinzile, unikezelo lwemarike luye lwanda kancinci kancinci, lwafikelela kwindawo ephezulu kunyaka, idatha kaJuni 29, imveliso yemihla ngemihla yepropylene oxide yasekhaya inokufikelela kwiitoni ezili-12,800, izinga lokusetyenziswa komthamo liyi-74.67%, unikezelo lwemarike lukhululekile.

KwiDragon Boat Festival, urhwebo lwemarike luzinzile kwaye lulula, icala lokubonelela linengcinezelo ethile kwifektri yemveliso, ixabiso liyathetha phantsi, isibonelelo sehle siye kwi-9200 yuan/ton (ifektri yokutshintshiselana ngeendawo yaseShandong) emva kweholide, ukubuyiswa kokuthunyelwa kwayo iyonke, kunciphisa uxinzelelo lwangaphambili kwimarike ukuba lunciphe, kodwa kulungelelaniswe iNissan kuphela, uluhlu oluthile lokugaya ukutya okuncinci, akukho santya sicacileyo sokunyuka, imeko yemarike izinzile.

Kwinkqubo elandelayo, isixhobo se-HPPO seTaixing Yida esiziitoni ezili-150,000 ngonyaka kunye nesixhobo se-Wanhua Phase 2 esiziitoni ezingama-300,000 ngonyaka kulindeleke ukuba siqalise kwakhona ekuqaleni kukaJulayi, isixhobo se-PO/SM seZhejiang esiziitoni ezingama-270,000 ngonyaka okwangoku siphantsi komthwalo omncinci, kwaye kulindeleke ukuba sibekwe kwimarike ekuqaleni kwenyanga, kunye ne-cashews ezikhulayo emantla nasezantsi. Ukuncipha kungama-300,000 kuphela eetoni ngonyaka zokulandelela okanye ukucima indawo yokupaka iJincheng, iyonke isaqhubeka ngokwanda, kwaye icala lokubonelela kunzima ukulixhasa.

二. Umgca weendleko zokubuyisa ixabiso lezinto ezisetyenzisiweyo ube ngumgca wokuzikhusela ngexabiso

Ngokuphathelele iindleko nenzuzo, ngexesha leeholide zeDragon Boat Festival, ixabiso lepropylene kunye ne-chlorine engamanzi linyukile, ingakumbi ixabiso le-chlorine engamanzi litshintshile ukusuka kwi-negative ukuya kwi-positive, kwaye ixabiso linyusiwe kakhulu. Ngexesha leeholide zeDragon Boat Festival, ixabiso le-hydrogen peroxide libuyele ngaphezulu kwe-8000 yuan/ton okokuqala. Kwangaxeshanye, ngokwembono yenkqubo ye-HPPO, ixabiso le-hydrogen peroxide linyuke kancinci, kwaye ixabiso lethiyori yi-9000-9200 yuan/ton. Ukunyuka koxinzelelo lweendleko zezixhobo ze-HPPO kukwaxhasa indlela yokucinga yemarike ukuya kwinqanaba elithile, kwaye abanye abangaphantsi bajonga umgca wokuqala wokukhusela amaxabiso e-CIC, balandela ngokulinganisela ukuthengwa, kwaye imakethi ivaliwe okwethutyana kwixabiso le-9200 yuan/ton emva komnyhadala.

Kwingxelo elandelayo, ixabiso lepropylene linokuba nokwehla okuncinci, kwaye ixabiso le-chlorine engamanzi kunye ne-hydrogen peroxide lidityaniswa kakhulu, nangona ixabiso lingasetyenziswa njengomgca wokuzikhusela ukudlala indima ethile exhasayo kwixabiso, kodwa impembelelo yeziseko zobonelelo kunye nemfuno inkulu kakhulu.

三. Ukuthenga okusezantsi kuthe saa ukulinda ngononophelo

Ngokwembono yecala leemfuno ezisezantsi, ukuthengwa kusasazeka kakhulu kulo lonke inyanga, kwaye imvakalelo yokuqala ye-bearish isalawulwa kukufuna nje ukulandela, kwaye ii-terminals ezisezantsi azinanjongo zokuqokelela. Ngamanye amaxesha, ukugcinwa ngengozi kwezixhobo enyangeni kubangela ukuba indawo iqine kancinci, kwaye ukuthengwa okusezantsi kuncinci, kodwa ukuzinza akwanelanga. Inzuzo yeshishini lesibini le-propylene glycol kunye ne-alcohol ether elisezantsi liphantsi, kwaye izinga lokusetyenziswa kwamandla oshishino liphantsi, nto leyo enenkxaso encinci kwimarike ye-cyclopropylene.

UJulayi olandelayo usesexesha lokungabikho kwemveliso, kunye nokwanda kwezixhobo zokubonelela ngoncedo, iimvakalelo zokwehla kwemveliso aziphucukanga kwaye ziyaqhubeka nokuthengwa ngononophelo, okulindeleke ukuba zifumane inkxaso encinci kwimarike.

Kulindeleke ukuba ihlale ibuthathaka emva kokungavisisani

Isiphelo (sexesha elifutshane):Ubonelelo kunye nemfuno yemarike ye-cyc ikwimeko entle, kwaye ikwingxaki okwangoku, kodwa kwiveki ezayo, ngenxa yokwanda kwezixhobo ezithile ekuqaleni kwenyanga, kunokubakho ukwehla okuncinci.

Isiphelo (sexesha eliphakathi nelide):NgoJulayi, ukunyuka kwecala lokubonelela kuyabonakala, inkxaso esezantsi ngaphandle kwexesha lonyaka ilinganiselwe, kunye nephethini yokubonelela kunye nemfuno iyanda ngakumbi, umgca wokuqala weendleko okanye impembelelo ilinganiselwe, ixabiso lemarike kusalindeleke ukuba lehle ikakhulu kuluhlu oluncinci, umkhwa uyancipha, kodwa ixabiso lendlela ye-chlorol njengomgca wesibini wokhuselo kulindeleke ukuba libe nenkxaso ethile kwimarike, kwaye ukwehla kuncinci ngakumbi. Kulindeleke ukuba ixabiso le-cyclopropyl litshintshe ngaphakathi koluhlu lweendleko ze-HPPO kunye neendleko ze-chlorol, kodwa kuyimfuneko ukuqwalasela ukuguquguquka okungalindelekanga komphezulu wesixhobo kunye nempembelelo yokunciphisa amandla obushushu aphezulu ehlotyeni. Ingqiqo yokusebenza kwexabiso le-cyC isasekelwe kubonelelo kunye nemfuno, yongezwa yindleko.

Isilumkiso somngcipheko: ukungaqiniseki kwexesha elinyukayo lomphezulu wesixhobo; Ukuba uxinzelelo lweendleko emva kokuba ishishini linomdla wokuqalisa; Imfuno ecaleni kokusetyenziswa kokwenyani.
