Kwiveki ephelileyo, imarike ye-epoxy resin yayibuthathaka, kwaye amaxabiso kwishishini awela ngokungapheliyo, okuqhelekileyo kube yi-bearish. Evekini, i-bisphenol A ekrwada yayisebenza kwinqanaba eliphantsi, kwaye enye imathiriyeli ekrwada, i-epichlorohydrin, iguquguquka ukuhla kuluhlu olumxinwa. Ixabiso lemathiriyeli ekrwada lilonke liye layenza buthathaka inkxaso yayo kwizinto ezithengiweyo. Izinto ezimbini eziluhlaza ziqhubekile nokuhla ngendlela ebuthathaka, kwaye imfuno yemarike yeresin ayizange iphucuke. Izinto ezininzi ezimbi ezikhokelele ekungakwazini ukufumana isizathu esilungileyo sexabiso le-epoxy resin. Iikowuteshini zenqanaba lesibini kunye nelesithathu iimpawu ze-LER kwimarike zinikezelwe kwi-15800 yuan/ton. Amaxabiso abavelisi abakhulu abaqhelekileyo baye bawela kwinqanaba eliphantsi kakhulu kulo nyaka, kwaye kusekho ulindelo lokunciphisa ixabiso.
Kwiveki ephelileyo, umzi-mveliso omkhulu oseJiangsu uye wema ukuze ulungiswe, yaye umthwalo wezinye izityalo utshintshe kancinci. Umthwalo oqalayo uwonke wehlile xa uthelekisa neveki ephelileyo. Ebudeni beveki, imfuno esezantsi yomlambo yayicolile, kwaye umoya weeodolo ezintsha wawulula. Kuphela kungoLwesithathu odlulileyo, umoya wokubuza kunye nokuzaliswa kwakhona uphuculwe kancinci, kodwa bekusalawulwa kukuphinda kufuneke. Uxinzelelo kubavelisi bentlaka yokuthumela ngenqanawa luphezulu, kwaye ezinye iifektri zivile ukuba uluhlu lwempahla luphezulu kancinane. Kukho i-margin eninzi kunikezelo, kwaye ingqwalasela yorhwebo lwemarike iphantsi.
I-Bisphenol A: Kwiveki ephelileyo, izinga lokusetyenziswa komthamo wezityalo zasekhaya ze-bisphenol A zazingama-62.27%, phantsi kweepesenti ze-6.57 ukusuka ngoNovemba 3. Kule veki ye-South Asia yokuvalwa kweplastiki kunye nokugcinwa kweplastiki, iNantong Star Bisphenol A Plant icwangciselwe ukuvalwa ukugcinwa kweveki enye ngoNovemba 7, kwaye i-Changthe icwangciswe kwi-industry ye-Industry ye-Industry iya kuvala okokuqala kwi-Chemical line. kuvalwe ngenxa yokusilela ngoNovemba 6, ekulindeleke ukuba ibe yiveki enye). I-Huizhou Zhongxin ivaliwe okwethutyana kangangeentsuku ezi-3-4, kwaye akukho kuguquguquka okucacileyo kumthwalo wezinye iiyunithi. Ke ngoko, izinga lokusetyenziswa kwamandla kwisityalo sasekhaya se-bisphenol A liyehla.
I-Epichlorohydrin: Kwiveki ephelileyo, izinga lokusetyenziswa kwamandla kwishishini lasekhaya le-epichlorohydrin lalingama-61.58%, linyuke nge-1.98%. Ngeveki, i-Dongying Liancheng 30000 t / isityalo sepropylene yavalwa ngo-Oktobha 26. Okwangoku, i-chloropropene iyona mveliso ephambili, kwaye i-epichlorohydrin ayizange iqalise kwakhona, kwaye ikwinkqubo yokulandelela; Imveliso yemihla ngemihla ye-epichlorohydrin yeQela le-Binhua yanda ukuya kwiitoni ze-125 ukulinganisa i-hydrogen chloride ephezulu; I-Ningbo Zhenyang 40000 t / isityalo senkqubo ye-glycerol yaqalwa kwakhona ngoNovemba 2, kwaye imveliso yemihla ngemihla yangoku malunga neetoni ezili-100; I-Dongying Hebang, i-Hebei Jiaao kunye ne-Hebei Zhuotai isekwimeko yokupaka, kwaye ixesha lokuqalisa kwakhona lilandela; Ukusebenza kwamanye amashishini kunotshintsho oluncinci.
Uqikelelo lwemarike yexesha elizayo
I-Bisphenol Ukuthengiswa kweemarike kunyuke kancinci kwimpelaveki, kwaye iifektri ezisezantsi zilumke kakhulu ekungeneni kwimarike. Abahlalutyi beemarike bakholelwa ukuba: ingqondo yabathengi kunye nabathengisi baya kuqhubeka bedlala imidlalo kwiveki ezayo, kunye notshintsho oluncinci kwizinto ezisisiseko zexesha elifutshane. Ulindelo olubuthathaka oluziswa sisixhobo esitsha luya kucinezela ingqondo yemarike, kwaye imarike kulindeleke ukuba ilungelelanise malunga nomgca weendleko.
Icyclic chloride yaqhubeka ibaleka. Uluhlu oluphezulu lwentlalo kunye namahemuhemu okuba iiyunithi eziphindwe kabini zaseNyakatho Mzantsi ziya kufakwa kwimveliso kwinyanga ezayo zenza abantu bemarike balumke kwaye umoya wokulinda kunye nokubona kwiimarike zahlala zingatshintshi. Ngokohlalutyo lwabangaphakathi, nangona imarike yangoku izinzile okwethutyana, kunokwenzeka ukuba imarike yexesha elizayo iya kuqhubeka nokuhla.
Ubonelelo lwemarike ye-LER alunayo nje imveliso eyongeziweyo yezixhobo zokulungisa, kodwa ikwanayo nemikhosi emitsha engena kwimarike. Kuyaqondwa ukuba isityalo se-epoxy eWuzhong, eZhejiang (i-Shanghai Yuanbang No.2 Factory) yafakwa ngempumelelo kulingo oluqhutywe kwiintsuku ezimbalwa ezidlulileyo. Emva kwebhetshi yesibini, umbala wemveliso ufikelele malunga ne-15 #. Ukuba iyaqhubeka nokuhlala izinzile kwixesha elizayo, imveliso ayiyi kungena kwimarike ixesha elide. I-LER iya kuqhubeka nokufowunelwa kwayo okubuthathaka, kunye nemfuno ephambili yokuthengwa kwempahla engqongqo, kwaye kunzima ukubona iimpawu zokubuyiswa kwexesha elifutshane.
