Kule veki iphelileyo, imakethi ye-Epoxy Rerin yayibuthathaka, kwaye amaxabiso akumzi-mveliso ayeke ngokungasebenziyo, eyayingasebenzi rhoqo. Evekini, i-bisphenol eluhlaza esebenza kwinqanaba eliphantsi, kwaye enye into eluhlaza, i-epichlorohydrin, iguqukele ezantsi kuluhlu olucekeceke. Ixabiso lezinto eziphathekayo zexabiso elipheleleyo liye labuthathaka inkxaso yayo kwiimpahla zendawo. Izinto eziluhlaza ezimbini ziqhubekile nokwehla ngendlela ebuthathaka, kwaye imfuno yentengiso ye-resin ayiphucukanga. Izinto ezimbi ezininzi ezikhokelela ekungakwazi ukufumana isizathu esihle sexabiso le-epoxy resin. Iikowuteshini ze-cier yesibini neyesibini ye-tier ye-ler kwimarike zisiwe ngo-15800 Yuan / Ton. Amaxabiso abavelisi abaphambili abaphambili baye bawela kwinqanaba eliphantsi kulo nyaka, kwaye kusekho ulindelo lokuncitshiswa kwamaxabiso.
Kule veki iphelileyo, umzi-mveliso omkhulu eJiangssu wema wesondlo, kwaye umthwalo wezinye izityalo utshintshile kancinci. Umthwalo oqala uphela unciphile xa kuthelekiswa neveki ephelileyo. Ebuweni, imfuno esezantsi ye-odolo yayiyigudi, kwaye imeko yemiyalelo emitsha yayikukukhanya. Kuphela ngoLwesithathu odlulileyo, umoya wokubuza kunye nokugcwaliswa kwakhona kwaphuculwe kancinane, kodwa kwakusenziwa ngokufumana nje ukuphinda ubuze kwakhona. Ingcinezelo ekuboniseni abavelisi be-resin ukuba inqanawa iphezulu, kwaye ezinye iifektri zivile ukuba uluhlu lweempahla luphezulu kancinci. Kukho umdaniso oninzi kwisithembiso, kwaye ugxininiso lokurhweba kwimakethi lusezantsi.
I-Bisphenol A: Iveki ephelileyo, inqanaba lokusetyenziswa kwesikhundla se-bisphenol yasekhaya yayingama-62.27%, i-6.57 i-onfic screen bispheness icwangcisiwe ukuba ivalwe imigca emibini eya kuvalwa ngenxa yokungaphumeleli ngoNovemba I-6, kulindeleke ukuba ibe yiveki enye). I-huizhou zhongxin ivaliwe okwethutyana iintsuku ezi-3-4, kwaye akukho dumo ngokucacileyo kumthwalo weeyunithi. Ke ngoko, inqanaba lokusebenzisa amanyathelo e-bisphenol yasekhaya isityalo siyancipha.
I-Epichlorozydrin: kwiveki ephelileyo, inqanaba lokusetyenziswa kwesikhundla seshishini le-Epichlozydrin yayingama-61.58%, up 1.98%. Kwiveki, i-piancheng liacheng i-30000 t / isityalo se-proplene savalelwa nge-26 ka-Okthobha. Okwangoku, i-chloroPopene yeyona mveliso iphambili, kwaye ikwinkqubo yokulandelwa; Iziphumo zemihla ngemihla ze-epichlohydrin yeqela le-binhua inyuke ukuya kwi-125 yeetoni zokulinganisa i-hydrogen chlorige; I-Ningbo Zheying 40000 T / Inkqubo ye-glycerol ye-Glycerol yaqala nge-2 kaNovemba, kunye nemveliso yemihla ngemihla malunga neetoni ezili-100; I-Dong Hebang, eHebei Jiaao noHebhee Zhuiotai basekwimeko yokupaka, kwaye ixesha lokuqalisa liyalandela; Ukusebenza kwamanye amashishini anotshintsho oluncinci.
Isimo sentengiso semali
I-Bisphenol i-turnover yentengiso ithathe kancinci ngempelaveki, kwaye iifeksi ezisezantsi zazilumkile kakhulu ekungeneni kwintengiso. Abahlalutyi bemakethi bakholelwa ukuba: Ingqondo yabathengi kunye nabathengisi baya kuqhubeka nokudlala imidlalo kwiveki ezayo, betshintshana ngezinto ezisisiseko. Izinto eziluncedo ezibuthathaka eziziswe sisixhobo esitsha ziya kucinezela ubuchule bentengiso, kwaye imakethi kulindeleke ukuba ihlengahlengise umgca wendleko.
I-cyclic chloride yaqhubeka nokuqhuba endle. Uluhlu oluphezulu lwentlalo kunye namahemuhemu ukuba iiyunithi eziPhezulu zoPhepha eziPhezulu zoMzantsi ziya kumiliselwa kwinyanga ezayo yenze abantu abathengi bentengiso kwaye belindile kwaye babone imeko yentengiso bahlala bengaguquki. Ngokutsho kohlalutyo lwangaphakathi, nangona imakethi yangoku iZizinza okwethutyana, kunokwenzeka ukuba imakethi yexesha elizayo iya kuqhubeka ukwehla.
Ukubonelelwa kwentengiso ye-ler ayinayo kuphela imveliso eyongezelelweyo yezixhobo zesondlo, kodwa inamandla amatsha angena kwintengiso. Kuyaqondwa ukuba isityalo se-Epoxy eWuzhong, Zhejiang (Shanghai Yuanbang No..2 Umzi-mveliso) wabekwa ngempumelelo kwityala elidlulileyo. Emva kwebhetshi yesibini, umbala wemveliso ufikelele kwi-15 #. Ukuba iyaqhubeka nokuzinza kwixesha elizayo, imveliso ayizukungena kwintengiso ixesha elide. I-Ler iya kuqhubeka nembuyekezo yayo ebuthathaka, enemfuno ikakhulu ekuthengweni kwengqondo, kwaye kunzima ukubona iimpawu zokubuyisa kwixesha elifutshane.
