Kugeza muri Nyakanga 2023, igipimo rusange cya epoxy resin mu Bushinwa cyarengeje toni miliyoni 3 ku mwaka, kigaragaza umuvuduko w’ubwiyongere bwihuse bwa 12.7% mu myaka yashize, aho iterambere ry’inganda rirenze umuvuduko w’ubwiyongere bw’imiti myinshi.Birashobora kugaragara ko mumyaka yashize, kwiyongera kwimishinga ya epoxy resin byihuse, kandi ibigo byinshi byashora imari kandi birateganya kubaka umushinga munini.Nk’uko imibare ibigaragaza, mu gihe kiri imbere igipimo cy’ubwubatsi bwa epoxy resin mu Bushinwa kizarenga toni miliyoni 2.8, kandi umuvuduko w’inganda uzakomeza kwiyongera kugera kuri 18%.
Epoxy resin ni polymerisation ya bispenol A na Epichlorohydrin.Ifite ibiranga imiterere yubukanishi buhanitse, guhuzagurika gukomeye, imiterere ya molekile yuzuye, imikorere myiza yo guhuza, kugabanuka gukira kugabanuka (ingano yibicuruzwa irahagaze, guhangayika imbere ni nto, kandi ntabwo byoroshye kumeneka), kubika neza, kurwanya ruswa, ituze ryiza, hamwe nubushyuhe bwiza (kugeza 200 ℃ cyangwa hejuru).Kubwibyo, ikoreshwa cyane mubitambaro, ibikoresho bya elegitoroniki, ibikoresho byinshi, ibifatika hamwe nizindi nzego.

Umusaruro wa epoxy resin muri rusange ugabanijwe muburyo bumwe n'intambwe ebyiri.Uburyo bumwe bwintambwe nugukora epoxy resin ukoresheje reaction ya bisphenol A na Epichlorohydrin, isanzwe ikoreshwa muguhuza uburemere buke bwa molekile hamwe nuburemere buke bwa epoxy resin;Uburyo bwintambwe ebyiri burimo gukomeza kwitwara kwa molekuline nkeya hamwe na bispenol A. Uburemere bukabije bwa epoxy resin irashobora guhuzwa hakoreshejwe intambwe imwe cyangwa intambwe ebyiri.
Intambwe imwe yintambwe ni ukugabanya bispenol A na Epichlorohydrin munsi ya NaOH, ni ukuvuga gukora impeta zifungura no gufunga loop mugihe kimwe.Kugeza ubu, umusaruro munini wa E-44 epoxy resin mu Bushinwa urahuzwa binyuze mu ntambwe imwe.Inzira ebyiri ni uko bispenol A na Epichlorohydrin bibyara diphenyl propane chlorohydrin ether hagati binyuze muri reaction reaction mu ntambwe yambere ikorwa na catalizator (nka Quaternary ammonium cation), hanyuma igakora reaction ifunze imbere ya NaOH kugirango kubyara epoxy resin.Ibyiza byuburyo bubiri ni igihe gito cyo kwitwara;Igikorwa gihamye, ihindagurika ryubushyuhe buto, byoroshye kugenzura;Igihe gito alkali yongeyeho irashobora kwirinda hydrolysis ikabije ya epichlorohydrin.Inzira ebyiri zintambwe yo guhuza epoxy resin nayo ikoreshwa cyane.

Inkomoko yishusho: Ubushinwa Amakuru yinganda
Ukurikije imibare ifatika, ibigo byinshi bizinjira muri epoxy resin inganda mugihe kiri imbere.Kurugero, toni 50000 yibikoresho bya elegitoroniki ya Hengtai / ibikoresho byumwaka bizashyirwa mubikorwa mu mpera za 2023, naho toni 150000 zumusozi wa Huangshan Meijia ibikoresho bishya / ibikoresho byumwaka bizashyirwa mubikorwa mu Kwakira 2023. Zhejiang Zhihe Ibikoresho bishya 100000 / ibikoresho byumwaka biteganijwe ko bizashyirwa mubikorwa mumpera za 2023, ibikoresho bya elegitoroniki byo muri Aziya yepfo (Kunshan), Ltd birateganya gushyira mubikorwa toni 300000 yumwaka ibikoresho nibikoresho hafi ya 2025, hamwe na Yulin Jiuyang High Technology Materials Co. , Ltd irateganya gushyira mu bikorwa ibikoresho 500000 toni / yumwaka hafi 2027. Dukurikije imibare ituzuye, izikuba kabiri mugihe kiri imbere nko muri 2025.

Kuki abantu bose bashora imari muri epoxy resin imishinga?Impamvu zisesengura nizi zikurikira:
Epoxy resin nibikoresho byiza bya elegitoroniki bipakira
Ikidodo ca elegitoronike bivuga urukurikirane rw'ibikoresho bya elegitoronike hamwe n'ibikoresho bifashisha mu gufunga ibikoresho bya elegitoroniki, harimo gufunga, gufunga, no kubumba.Ibikoresho bya elegitoroniki bipfunyitse birashobora gukinisha amazi, kutagira inkuba, kutagira umukungugu, kurwanya ruswa, gukwirakwiza ubushyuhe, n’uruhare rw’ibanga.Kubwibyo, kole igomba gupakirwa ifite ibiranga ubushyuhe bwo hejuru, kurwanya ubushyuhe buke, ingufu za Dielectric nyinshi, kubika neza, kurengera ibidukikije n'umutekano.
Epoxy resin ifite ubushyuhe buhebuje, kubika amashanyarazi, gufunga, imiterere ya dielectric, imiterere yubukanishi, no kugabanuka guke hamwe no kurwanya imiti.Nyuma yo kuvangwa nubuvuzi bukiza, burashobora kugira imikorere myiza nibiranga ibintu byose bisabwa mugupakira ibikoresho bya elegitoroniki, kandi bikoreshwa cyane mubice nko gupakira ibikoresho bya elegitoroniki.
Dukurikije imibare yaturutse mu kigo cy’igihugu gishinzwe ibarurishamibare, umuvuduko w’ubwiyongere bw’inganda zikora amakuru mu buryo bwa elegitoronike mu 2022 wiyongereyeho 7,6% umwaka ushize, naho umuvuduko w’imikoreshereze y’ibicuruzwa bimwe na bimwe bya elegitoroniki urenga 30%.Birashobora kugaragara ko inganda za elegitoroniki zo mu Bushinwa zikiri mu nzira y’iterambere ryihuse, cyane cyane mu nganda za elegitoroniki zireba imbere nka semiconductor na 5G Mu rwego nk’ubwenge bw’ubukorikori na interineti y’ibintu, umuvuduko w’ubunini bw’isoko wahozeho imbere.
Kugeza ubu, ibigo bimwe na bimwe bya epoxy resin mu Bushinwa bihindura imiterere y’ibicuruzwa no kongera imigabane y’ibicuruzwa bya epoxy resin bijyanye n’inganda zikoresha ibikoresho bya elegitoroniki.Byongeye kandi, ibyinshi mu bigo bya epoxy resin biteganijwe kubakwa mubushinwa byibanda cyane kubintu byerekana ibikoresho bya elegitoroniki.
Epoxy resin nibikoresho byingenzi byumuyaga wa turbine
Epoxy resin ifite imiterere myiza yubukanishi, imiti itajegajega, hamwe no kurwanya ruswa, kandi irashobora gukoreshwa nkibikoresho byubatswe, umuhuza, hamwe n’amashanyarazi y’umuyaga.Epoxy resin irashobora gutanga imbaraga nyinshi, gukomera kwinshi, hamwe no kurwanya umunaniro, bigatuma umutekano uhagaze neza kandi wizewe, harimo imiterere ifasha, skeleton, hamwe no guhuza ibice byicyuma.Byongeye kandi, epoxy resin irashobora kandi kunoza imishwarara yumuyaga no kurwanya ingaruka zicyuma, kugabanya kunyeganyega n urusaku rwibyuma, no kunoza imikorere yumuriro wumuyaga.
Mu gutwikira umuyaga wa turbine, gukoresha epoxy resin nabyo ni ngombwa cyane.Mugutwikiriye hejuru yicyuma hamwe na epoxy resin, kurwanya kwambara no kurwanya UV birwanya ibyuma birashobora kunozwa, kandi igihe cyumurimo wicyuma kirashobora kongerwa.Muri icyo gihe, irashobora kandi kugabanya uburemere no kurwanya ibyuma no kunoza imikorere y’amashanyarazi.
Kubwibyo, epoxy resin igomba gukoreshwa cyane mubice byinshi byinganda zumuyaga.Kugeza ubu, ibikoresho byinshi nka epoxy resin, fibre karubone, na polyamide bikoreshwa cyane nkibikoresho byo kubyara ingufu z'umuyaga.
Imbaraga z'umuyaga w'Ubushinwa ziri ku mwanya wa mbere ku isi, aho impuzandengo ya buri mwaka izamuka irenga 48%.Gukora ibikoresho bifitanye isano ningufu zumuyaga nimbaraga nyamukuru zitera kwiyongera byihuse byokoresha ibicuruzwa bya epoxy resin.Biteganijwe ko umuvuduko w’inganda zikoresha ingufu z’umuyaga mu Bushinwa uzakomeza kwiyongera kurenga 30% mu gihe kiri imbere, kandi ikoreshwa ry’ibisigazwa bya epoxy mu Bushinwa na byo bizerekana ko iterambere ryiyongera.
Epoxy yihariye kandi idasanzwe izaba inzira nyamukuru mugihe kizaza
Inzira yo hasi ya porogaramu ya epoxy resin ni nini cyane.Nubwo biterwa niterambere ryinganda nshya zingufu, inganda zateye imbere byihuse mubipimo, iterambere ryimikorere, itandukaniro, ninzobere nabyo bizaba imwe mubyerekezo byingenzi byiterambere byinganda.
Icyerekezo cyiterambere cya epoxy resin yihariye ifite icyerekezo gikurikira.Ubwa mbere, ikibaho cyumuringa kitagira halogene gifite icyifuzo cyo gukoresha umurongo wa fenolike epoxy resin na Bisphenol F epoxy resin;Icya kabiri, ibikenerwa byo gukoresha o-methylphenol formaldehyde epoxy resin hamwe na hydrogenated bisphenol Resin ya epoxy iriyongera cyane;Icya gatatu, ibiryo byo mu rwego rwa epoxy resin nigicuruzwa cyongeye kwezwa na epoxy resin gakondo, gifite ibyerekezo bimwe byiterambere mugihe gikoreshwa mubikono byicyuma, byeri, ibinyobwa bya karubone, hamwe nu mutobe wimbuto;Icya kane, umurongo wibikorwa byinshi bya resin ni umurongo utanga umusaruro ushobora kubyara epoxy resin zose hamwe nibikoresho fatizo, nkibikoresho bisukuye byo mu rwego rwo hasi..
Ku ruhande rumwe, itwarwa nogukoresha murwego rwo hasi rwa elegitoroniki, naho kurundi ruhande, uburyo butandukanye bwo gukoresha no kugaragara kwa moderi nyinshi zo mu rwego rwo hejuru byazanye ahantu henshi hashobora gukoreshwa mu nganda za epoxy resin.Biteganijwe ko mu gihe kizaza ikoreshwa ry’inganda zitwa epoxy resin mu Bushinwa zizakomeza kwiyongera byihuse hejuru ya 10%, kandi iterambere ry’inganda za epoxy rirashobora kwitezwaho.
