Muna 2022, ethylene yekugadzira ethylene yeChina yakasvika 49.33 miriyoni matani, yakapfuura United States, ikava mugadziri mukuru wepasi rose we ethylene, ethylene yakaonekwa sechiratidzo chakakosha chekuona chiyero chekugadzira cheindasitiri yemakemikari.Zvinotarisirwa kuti panosvika 2025, huwandu hweChina hwekugadzira ethylene huchapfuura matani emamiriyoni makumi manomwe, izvo zvinozozadzisa zvinodiwa mudzimba, kana zvimwe zvakasara.

Indasitiri ye ethylene ndiyo musimboti weindasitiri yepetrochemical, uye zvigadzirwa zvayo zvinodarika 75% yezvigadzirwa zvepetrochemical uye zvinotora chinzvimbo chakakosha muhupfumi hwenyika.

Ethylene, propylene, butadiene, acetylene, benzene, toluene, xylene, ethylene oxide, ethylene glycol, etc. Inogadzirwa nemafuta ethylene, ndiwo magadzirirwo ezvinyorwa zvesimba idzva uye minda itsva yezvinhu.Pamusoro pezvo, mutengo wekugadzira ethylene unogadzirwa nehukuru hwakabatanidzwa hwekunatsa uye mabhizinesi emakemikari wakaderera.Kuenzaniswa nemabhizinesi ekunatsa echiyero chakafanana, kukosha kwakawedzerwa kwezvigadzirwa zvekunatswa zvakabatanidzwa uye mabhizinesi emakemikari zvinogona kuwedzerwa ne25% uye kushandiswa kwesimba kunogona kudzikiswa ne15%.

Polycarbonate, lithium bhatiri separator, photovoltaic EVA (ethylene - vinyl acetate copolymer) inogona kugadzirwa kubva ethylene, alpha olefin, POE (polyolefin elastomer), carbonate, DMC (dimethyl carbonate), ultra-yakakwirira molecular uremu hwe polyethylene (UHMWPE) nezvimwe zvigadzirwa zvitsva.Zvinoenderana nenhamba, kune gumi nemasere marudzi ethylene yakadzika zvigadzirwa zvine chekuita nesimba idzva, zvinhu zvitsva uye mamwe maindasitiri ane mhepo.Nekuda kwekukurumidza kusimudzira kwesimba idzva uye maindasitiri matsva senge mota nyowani dzemagetsi, photovoltaic uye semiconductors, kudiwa kwezvinhu zvitsva zvigadzirwa kuri kuwedzera.

Ethylene, semusimboti weindasitiri yepetrochemical, inogona kunge iri mukuwedzera, ichimaka iyo petrochemical indasitiri yakatarisana nekudzokororwa uye kusiyanisa.Kwete chete mabhizinesi emakwikwi anobvisa mabhizinesi ekumashure, iyo yepamusoro soro inobvisa iyo yekudzokera kumashure, asi zvakare kuparara uye kuzvarwa patsva kwemabhizinesi anotungamira ethylene yakadzika indasitiri chain chikamu.

Makambani makuru anogona kuchinja

Ethylene inogona kunge iri mune yakawandisa, ichimanikidza kukwenenzverwa kwakabatanidzwa uye makemikari mayuniti kuti arambe achiwedzera ketani, kuwedzera ketani uye kusimbisa cheni kuvandudza kukwikwidza kwechikwata.Kutanga kubva kumafuta asina kuchena, zvinodikanwa kuvaka iyo yakaomeswa zvinhu mukana wekubatanidzwa.Chero bedzi paine tarisiro yemusika kana zvigadzirwa zvine humwe huwandu hwemusika, mutsara unodhirowewa, uyo zvakare unomhanyisa kubviswa kwevanokunda uye vanorasikirwa muindasitiri yese yemakemikari.Kugadzirwa uye maitiro ezvigadzirwa zvemakemikari akawanda uye zvigadzirwa zvakanaka zvemakemikari zvinounza shanduko.Mhando dzekugadzira uye chiyero chinozowedzera uye chinowedzera, uye huwandu hwemabhizinesi huchadzikira zvishoma nezvishoma.

Midziyo yekutaurirana, nharembozha, midziyo inopfekwa uye zvimwe zvemagetsi zvevatengi, hungwaru hwemotokari, minda yehungwaru yemidziyo yemumba iri kukura nekukurumidza, zvichifambisa kukurumidza kukura kwekudiwa kwezvinhu zvitsva zvemakemikari.Izvi zvitsva zvemakemikari zvinhu uye monomer inotungamira mabhizinesi ane maitiro ekukura anoshanduka nekukurumidza, senge 18 nyowani simba uye zvigadzirwa zvitsva zvemukati pasi pe ethylene.

Fan Hongwei, sachigaro weHengli Petrochemicals, akataura kuti kuchengetedza kwakasimba kukwikwidza kwakasimba uye kutora mamwe mapoinzi matsva muhurongwa hwese indasitiri chain mashandiro idambudziko rinoda kutariswa.Isu tinofanirwa kupa kutamba kwakazara kune zvakanakira indasitiri yekumusoro, kuwedzera uye kudzamisa indasitiri yeindasitiri yakatenderedza zvigadzirwa zvepasi kuti tigadzire mabhenefiti matsva emakwikwi, uye kuyedza kusimudzira kuwedzera kwakasimba kwezvigadzirwa zvepasi kuti zvivake cheni yakanaka yeindasitiri yemakemikari.

Kang Hui New Material, inotsigira Hengli Petrochemical, inogona kuburitsa 12 micron silicon kuburitsa laminated lithium bhatiri yekudzivirira firimu online, Hengli Petrochemical inogona misa kuburitsa zvakatemwa 5DFDY zvigadzirwa, uye yayo MLCC yekuburitsa base firimu maakaundi anodarika makumi matanhatu neshanu muzana ekugadzirwa kwepamba.

Kutora kunatsa uye kubatanidzwa kwemakemikari sepuratifomu yekuwedzera yakatwasuka uye yakatwasuka, isu tinowedzera nekusimbisa niche nzvimbo uye kuumba kusimudzira kwakabatana kwenzvimbo dze niche.Kana kambani yangopinda mumusika, inogona kupinda mumabhizinesi anotungamira.Iwo 18 mabhizinesi anotungamira emagetsi matsva uye zvigadzirwa zvitsva zvepasi peethylene anogona kutarisana nekushanduka kwevaridzi vobva pamusika.

Muchokwadi, pakatanga 2017, Shenghong Petrochemicals yakatanga mazana matatu ezviuru ematoni / gore EVA vachishandisa zvakanakira iyo yese indasitiri cheni, kupera kwe2024 zvishoma nezvishoma kuchaisa mukugadzira mamwe 750,000 matani eEva, kuti aiswe mukugadzirwa muna 2025, ne ipapo, Shenghong Petrochemicals ichava iyo huru-yekupedzisira yepamusoro-yekupedzisira EVA yekugovera base.

China iripo kemikari yevasungwa, nhamba yemapaki uye mabhizinesi mumatunhu makuru emakemikari achaderedza zvishoma nezvishoma, Shandong anopfuura 80 mapaki emakemikari achatoita zvishoma nezvishoma kuderedza kusvika hafu, Zibo, Dongying nedzimwe nzvimbo dzemabhizimusi emakemikari akazara achabviswa hafu.Kune kambani, kwete iwe hauna kunaka, asi vakwikwidzi vako vakasimba kwazvo.

"Zviri kuramba zvichioma" kuderedza mafuta uye kuwedzera chemistry

"Kudzikiswa kweoiri uye kuwedzera kwemakemikari" yave shanduko yekutungamira yekunatsa mafuta epamba uye indasitiri yemakemikari.Ikozvino kushandura chirongwa chezvinochenesa chinonyanya kuburitsa basic organic makemikari mbishi zvinhu senge ethylene, propylene, butadiene, benzene, toluene uye xylene.Kubva pamaitiro ezvino ekuvandudza, ethylene uye propylene zvichine imwe nzvimbo yekuvandudza, nepo ethylene inogona kunge iri mune yakawandisa, uye zvichava zvakanyanya kuoma "kuderedza mafuta uye kuwedzera kemikari".

Chokutanga pane zvose, zvakaoma kusarudza mapurojekiti uye zvigadzirwa.Kutanga, kudiwa kwemusika uye huwandu hwemusika zviri kuramba zvichinetsa kusarudza zvigadzirwa zvine tekinoroji yakakura.Chechipiri, kune kudiwa kwemusika uye huwandu hwemusika, zvimwe zvigadzirwa zvinoenderana zvachose nezvigadzirwa zvinotengeswa kunze kwenyika, hazvigone tekinoroji yekugadzira, senge yakakwira-end synthetic resin zvinhu, high-end synthetic rubber, high-end synthetic fibers uye monomers, yakakwirira. -kuguma carbon fiber, engineering plastics, high-purity electronic chemicals, etc .. Zvose izvi zvigadzirwa zvinotarisana nedambudziko re "mutsipa", uye zvigadzirwa izvi hazvibviri kuunza seti yakakwana ye teknolojia, uye inogona kungowedzera mari mukutsvakurudza uye development.

Iyo indasitiri yese kuderedza mafuta uye kuwedzera makemikari, uye pakupedzisira inotungamira kune yakawandisa kugona kwemakemikari zvigadzirwa.Mumakore achangopfuura, iyo yekunatsa uye yemakemikari yekubatanidza purojekiti inonyanya kukoshesa "kuderedza mafuta uye kuwedzera chemistry", uye aripo ekunatsa uye emakemikari mabhizinesi anotorawo "kuderedza mafuta uye kuwedzera chemistry" segwara rekushandura nekusimudzira.Mumakore maviri kusvika matatu apfuura, huwandu hutsva hwemakemikari hweChina hwakada kudarika huwandu hwemakore gumi apfuura.Indasitiri yose yokunatsa iri “kuderedza oiri uye kuwedzera kemisitiri.Mushure mepamusoro pekugadzirwa kwekemikari, iyo indasitiri yese inogona kunge iine chikamu chekuwedzera kana kuwandisa.Zvizhinji zvemakemikari matsva uye zvigadzirwa zvemakemikari zvakanaka zvine misika midiki, uye chero bedzi paine budiriro mune tekinoroji, pachava nekumhanyisa, zvichitungamira mukuwedzeredza uye kurasikirwa kwepurofiti, uye kunyange muhondo yemutengo mutete.
