1 、Imbaraga zisoko ryibikoresho fatizo

1.Bisphenol A: Icyumweru gishize, igiciro cyibibanza cya bispenol A cyerekanye ihindagurika ryizamuka. Kuva ku ya 12 Mutarama kugeza ku ya 15 Mutarama, isoko rya bispenol Isoko ryagumye rihamye, aho abayikora bohereje bakurikije ibicuruzwa byabo bwite ndetse n’injyana yabo yo kugurisha, mu gihe abaguzi bo hasi bakenera byihutirwa baguze ibintu byoroshye bakurikije uko isoko ryifashe.

Icyakora, guhera ku wa kabiri, igiciro cyibikoresho fatizo benzene yazamutse cyane, bituma izamuka ry’ibiciro bya ketone ya fenolike, bityo byongera igiciro cy’umusaruro wa bispenol A. Guhura n’iki kibazo, ubushake bw’abakora ibicuruzwa n’abahuza kuri kuzamura ibiciro byazamutse cyane. Muri icyo gihe, amasoko yo hepfo nayo arimo guhunika cyane, guteza imbere ibikorwa byubucuruzi byiyongera ku isoko rya bisphenol A. Kubera iyo mpamvu, ibiciro byisoko mu turere dutandukanye byagiye byiyongera kuburyo butandukanye. Ku wa kane mu gitondo ubucuruzi, ibiciro byavuzwe haruguru bya bispenol A byariyongereye bigera kuri 9600 yu / toni, kandi ibiciro mu tundi turere nabyo byariyongereye. Ariko, kubera guhindagurika no guhuriza hamwe gato kw'ibiciro fatizo byo hejuru, ishyaka ryo kugura ku isoko ryo hasi ryarakonje, kandi ibintu byo mu rwego rwo hejuru byagabanutse.

Amakuru yerekana ko igipimo cy’inganda cyageze kuri 70.51% mu cyumweru gishize, kikaba cyiyongereyeho 3,46% ugereranije n’icyumweru gishize. Guhera ku ya 19 Mutarama, igiciro rusange cyumvikanyweho na bisphenol A mu Bushinwa bwo mu Burasirazuba gishingiye kuri 9500-9550 Yuan / toni, kikaba cyiyongereyeho 75 Yuan / toni ugereranije na 12 Mutarama.

2. Epichlorohydrin: Icyumweru gishize, isoko rya epichlorohydrin ryakoraga neza. Mu cyumweru, kubera izamuka ry’ibiciro by’ibikoresho fatizo propylene na chlorine y’amazi, hamwe n’imihindagurikire idahwitse ya glycerol, igiciro cy’umusaruro wo gutegura epichlorohydrin ukoresheje uburyo bwa propylene cyiyongereye, kandi n’inyungu rusange yagabanutse.

Kugeza ubu, isoko ryamasoko nibisabwa birasa nkintege nke, kandi ababikora muri rusange bafite imyifatire yubwitonzi, hamwe nibisobanuro bihamye. Twabibutsa ko ibikoresho nka Dongying Liancheng, Binhua Group, na Zhejiang Zhenyang bikiri mu gihagararo, mu gihe ibindi bigo bitanga umusaruro byibanda cyane cyane ku musaruro no kuwukoresha, kandi umutungo uhari ni muto. Nyamara, abacuruzi bamwe ntibafite ikizere ku isoko ry'ejo hazaza, bigatuma habaho isoko ridahenze ku isoko. Isoko ryo hasi ryisoko ryuzuye nyuma yo kuzuzwa mubyiciro byambere, bigatuma igabanuka ryibazwa ryibicuruzwa bishya byinjira kumasoko. Byongeye kandi, mugihe ikiruhuko cyibiruhuko cyegereje, ibigo bimwe na bimwe byo hepfo birashobora gufata ikiruhuko hakiri kare, ibyo bikarushaho kunaniza umwuka wubucuruzi ku isoko. Hagati aho, ibikorwa nyabyo birashobora kumvikana byoroshye.

Ku bijyanye n’ibikoresho, igipimo cy’inganda cyagumye ku rwego rwa 42.01% mu cyumweru gishize. Guhera ku ya 19 Mutarama, igiciro rusange cyumvikanyweho cya epichlorohydrin mu Bushinwa bwo mu Burasirazuba gishingiye kuri 8300-8400 Yuan / toni.

2 、Tanga isesengura ryibihe

Icyumweru gishize, imikorere yimikorere murugoepoxy resininganda zateye imbere gato. By'umwihariko, igipimo cyimikorere ya resin yamazi ni 50.15%, mugihe igipimo cyimikorere ya resin ikomeye ni 41.56%. Igipimo rusange cy’inganda cyageze kuri 46.34%, cyiyongereyeho 0% ugereranije nicyumweru gishize. Uhereye kumikorere, ibikoresho byinshi byamazi bigumana imikorere ihamye, mugihe ibikoresho bikomeye bya resin bikomeza urwego rusanzwe. Muri rusange, igipimo cyimikorere yinganda ziriho ubu ni gito, kandi hari ibicuruzwa bihagije kurubuga.

3 、Impinduka kuruhande rusabwa

Ibisabwa muri rusange kumasoko yo hepfo yerekana ibiranga amasoko ateganijwe, hamwe nibisabwa bike. Muri icyo gihe, ibigo bimwe byo hasi byinjiye buhoro buhoro aho imodoka zihagarara, bikomeza kugabanuka ku isoko.

4 、Iteganyirizwa ry'isoko ry'ejo hazaza

Biteganijwe ko isoko rya epoxy resin rizakomeza guhindagurika gake muri iki cyumweru. Ihinduka ryibiciro kuruhande rwibiciro biteganijwe ko rizakomeza guhagarara neza, mugihe isoko ryo hasi risabwa gukurikiranwa nabyo bizaba bike. Mugihe ibigo bimwe byamanuka buhoro buhoro biva kumasoko muminsi mikuru, umwuka wubucuruzi kumasoko urashobora gukomeza guceceka. Muri ibi bihe, ku bakora ibikorwa by’ivunjisha bazarushaho kugira amakenga mu kureba imikorere y’isoko n’imihindagurikire y’ibisabwa, mu gihe banita ku mikorere y’isoko ryo hejuru no mu majyepfo no guteza imbere icyifuzo.
