I-Liquid Epoxy Resin

Incazelo yokukhiqiza

Liquid I-Epoxy Resin iyancibilika ku-benzene, toluene, xylene, acetone nezinye izinyibilikisi zemvelo. I-fluidity enhle, kulula ukuyixuba nezinto ezisizayo, ukubumba okulula nokucutshungulwa, ukuzinza okuhle kwe-dimensional ngemva kokwelashwa, ukushwabana kungaphansi kuka-2%, kuyinhlaka enezinga lokushwabana elincane kakhulu le-thermosetting resin, i-thermal expansion coefficient 6-10.5% - ukubopha okuhle kakhulu ukusebenza, ukusebenza kahle kokufakwa kukagesi, ukusebenza kwemishini kanye nokuzinza kwamakhemikhali.

Isicelo

1. Ukuthelwa kwamaphakheji okufaka izinto zikagesi namamothoni: ukukhiqizwa kwamaphakheji okufaka ugesi avalwe ngokuphelele ezinto zikagesi ezinamandla kagesi aphezulu naphansi ezifana nozibuthe, amakhoyili okuxhumana, ama-transformer, uhlobo olomile, njll. Ithuthuke ngokushesha embonini kagesi. . Ithuthuke isuka ekuthululeni ingcindezi evamile kanye nokuthululwa kwe-vacuum kuya ekwakhekeni kwejeli yokucindezela okuzenzakalelayo.

2. I-Liquid Epoxy Resin isetshenziswa kabanzi ukuhlanganisa kanye nokwahlukanisa amadivaysi anezingxenye ze-elekthronikhi namasekethe. Sekuyizinto ezibalulekile futhi ezibalulekile zokuvikela embonini ye-elekthronikhi.

3. Inhlanganisela ye-electron grade epoxy molding isetshenziselwa ukupakishwa kwepulasitiki yezingxenye ze-semiconductor. Ithuthuke ngokushesha kakhulu eminyakeni yamuva. Ngenxa yokusebenza kwayo okuphezulu, inomkhuba omuhle wokufaka esikhundleni sensimbi yendabuko, i-ceramic kanye nengilazi.

4. Ipulasitiki ye-Epoxy laminated isetshenziswa kakhulu emikhakheni kagesi nekagesi. Ukuthuthukiswa kwe-epoxy copper clad laminate kuyashesha kakhulu, futhi sekungenye yezinto eziyisisekelo embonini ye-elekthronikhi. Ngaphezu kwalokho, i-epoxy insulating coatings, insulating adhesives kanye ne-adhesive kagesi nayo isetshenziswa kabanzi.

5. Amapulasitiki wobunjiniyela nezinto eziyinhlanganisela: amapulasitiki obunjiniyela be-epoxy ikakhulukazi ahlanganisa izinto zokubumba ze-epoxy, amapulasitiki e-epoxy laminated kanye namapulasitiki e-epoxy foam asetshenziselwa ukubumba okunomfutho ophezulu. Amapulasitiki obunjiniyela be-epoxy nawo angathathwa njengohlobo lwezinto ezihlanganisiwe ze-epoxy composite. Izinhlanganisela ze-epoxy ikakhulukazi zifaka amapulasitiki aqiniswe nge-epoxy glass fibre (inhlanganisela evamile) kanye nezinhlanganisela zesakhiwo se-epoxy, njengamaphrofayili e-epoxy aphukile, imikhiqizo ye-rotary engenalutho kanye nezinhlanganisela ezisebenza kahle kakhulu. I-epoxy composite iyinto ebalulekile yesakhiwo futhi esebenzayo embonini yamakhemikhali, ezondiza, i-aerospace, ezempi kanye nezinye izinkambu zobuchwepheshe obuphezulu.

6. Izinto ezisetshenziswa umphakathi zisetshenziswa kakhulu njenge-anti-corrosion floor, udaka lwe-epoxy kanye nemikhiqizo kakhonkolo, umgwaqo ogandayiwe wezinga eliphezulu kanye nomzila wezindiza, izinto zokulungisa ngokushesha, izinto zokugaya ukuze kuqiniswe isisekelo, izinto zokunamathisela nezingubo zokugqoka, njll.

Isakhiwo kanye Nobuntu

Izakhiwo eziphezulu zemishini. I-Liquid Epoxy Resin inokubumbana okuqinile kanye nesakhiwo samangqamuzana aminyene, ngakho-ke izakhiwo zayo zemishini ziphakeme kunalezo ezijwayelekile ze-thermosetting resin njenge-phenolic resin ne-polyester engagcwalisiwe.

Ukunamathela okuqinile. Uhlelo lokuphulukisa lwe-epoxy resin luqukethe iqembu le-epoxy, iqembu le-hydroxyl, isibopho se-ether, isibopho se-amine, isibopho se-ester namanye amaqembu ase-polar anomsebenzi omkhulu, ohlinzeka ngezinto eziphulukisiwe ze-epoxy ngokunamathela okuhle kakhulu kuma-polar substrates njengensimbi, i-ceramics, ingilazi, ukhonkolo. kanye nezinkuni.

Ukucutshungulwa okuhle: i-epoxy resin empeleni ayikhiqizi ama-molecular volatiles aphansi lapho yelashwa, ngakho-ke ingabunjwa ngaphansi kwengcindezi ephansi noma ingcindezi yokuxhumana. I-Epoxy resin E44 ingasetshenziswa nama-ejenti okwelapha ahlukahlukene ukwenza izimbotshana ezingancibiliki, eziqinile, eziyimpushana, okokunamathela emanzini nokunye okokuhambisana nemvelo.

Ukufakwa kukagesi okuhle kakhulu: I-epoxy resin ingenye yezinhlobo ezinhle kakhulu ze-thermosetting resin enezindawo zikagesi eziphakathi nendawo.

Ukuzinza okuhle nokumelana namakhemikhali. I-epoxy resin ngaphandle kokungcola okufana ne-alkali nosawoti akulula ukuwohloka. Uma nje igcinwe kahle (ivaliwe, ingenawo umswakama kanye nokushisa okuphezulu), isikhathi sokugcina unyaka ongu-1. Ingase isetshenziswe uma idlula ukuhlolwa ngemva kokuphelelwa yisikhathi. I-epoxy curing compound inokuqina okuhle kwamakhemikhali. Ukumelana nokugqwala kwayo ku-alkali, i-asidi, usawoti kanye neminye imithombo yezindaba ingcono kune-resin ye-polyester engagcwalisiwe, i-phenolic resin nezinye izinhlaka ze-thermosetting. Ngakho-ke, i-epoxy resin isetshenziswa kabanzi njenge-anti-corrosion primer. Ngenxa yokuthi i-epoxy resin ephulukisiwe inesakhiwo senethiwekhi enezinhlangothi ezintathu futhi imelana nokufakwa kukawoyela, isetshenziswa kakhulu odongeni lwangaphakathi lwamathangi kawoyela, amathangi kawoyela nezindiza.

Umehluko Phakathi kwe-E44 ne-E51

Inani le-epoxy liyinkomba ebaluleke kakhulu yokuhlonza izakhiwo ze-epoxy resin, futhi amamodeli e-epoxy resin yezimboni ahlukaniswa ngokwamanani ahlukene e-epoxy. Inani le-epoxy libhekisela enanini lokuqhuma kwezinto ezisekelwe epoxy eziqukethwe kuwo wonke ama-100g eresin. I-E-51 iwumkhiqizo, emele i-epoxy emaphakathi (51/100=0.51, inani le-epoxy N/100 ngu-0-18-0.54). I-E-44 epoxy resin imele isilinganiso senani le-epoxy lika-44/100, futhi (0.41-0.47) i-epoxy resin enevelu ephezulu ye-epoxy ine-viscosity ephansi, i-viscosity ephezulu kanye nokuqina okuphezulu ngemva kokwelapha.

Izisetshenziswa Zomkhakha

I-Hebei Linyuan Fine Chemical Co., Ltd. yasungulwa ngoJanuwari 2017, futhi yaxhaswa futhi yakhiwa yi-Hebei JingHong Electronic Technology Co., Ltd kanye nenkampani engaphansi kwayo i-Hongda Insulation Material Factory esebenza ngokukhethekile ekukhiqizeni i-3240 Epoxy Resin Board, i-FR4 Fiberglass. Ishidi, I-Phenolic Cotton Cloth Laminate Sheet 3026, i-phenolic paper board kanye ne-copper clad laminate.

I-JingHong yayinemboni ngaphambili e-Xionng'an New District, e-Hebei, eyakhiqiza i-E44 epoxy resin kuphela. Umthamo wokukhiqiza wawumncane futhi ingxenye yawo yayisetshenziselwa wona. Ngakho-ke, kwakungekho ukuthengisa okuningi emakethe. Ngenxa yokusetshenziswa okubanzi kwe-epoxy resin, i-China isibe ngumkhiqizi nomthengi omkhulu kunayo yonke emhlabeni wama-epoxy resin. Ukuze ihambisane nokuthambekela kwemakethe, inkampani yahlanganisa isimo senkampani, yahoxa e-Xionng'an New Area, futhi yakha imboni ye-epoxy resin ekhipha amathani angu-20,000 ngonyaka eCangzhou. Iphrojekthi isiqediwe futhi yafakwa ekukhiqizeni.

Le phrojekthi yakhelwe kusetshenziswa ubuchwepheshe baseJapan iToto Kasei. Ukukhiqizwa kwamanje kwama-epoxy resins kufaka phakathi i-E44, i-E51, njll., futhi izinhlobo zizongezwa kancane kancane ngokuya ngesidingo semakethe esikhathini esizayo. Umuntu ophethe inkampani uthe: Njengamanje, umthamo wokukhiqiza i-epoxy resin ungamathani angama-20,000. Ngokwesimo sangempela semakethe, amandla okukhiqiza azokhula abe amathani ayi-100,000.

Isitoreji Nokuthumela

Uma ugcina i-epoxy resin, sicela uqhelelane nelanga eliqondile, umthombo wokushisa, indawo yokuthungela nokungangeni kwamanzi. Izimpahla eziyingozi zizogcinwa ngokuvumelana nemithethonqubo. Uma zingasetshenzisiwe ngemuva kokuvulwa, zizovalwa ukuze zigcinwe. Isikhathi seshelufu se-epoxy resin ngokuvamile siyiminyaka engu-1, futhi singasetshenziswa ngemva kokuphumelela ukuhlolwa kabusha. Ngaphansi kwezimo ezihambisanayo, njengokugcinwa endaweni ebanda kakhulu, amanye ama-epoxy resins angase acwebezele, okuwushintsho olungokomzimba kuphela futhi olungashintshi izakhiwo zawo zamakhemikhali. Uma kwenzeka i-crystallization, i-resin ingashiswa ibe ngu-70-80 ° C futhi ibuyiselwe esimweni sayo sokuqala ngokushukumisa.

Ukusetshenziswa

  I-epoxy resin ayivamisile ukusetshenziswa iyodwa. Ngokuvamile, kusetshenziswa izinto ezisizayo ezifana nesigcwalisi se-ejenti yokwelapha. Izingxube ze-amine ezisezingeni eliphezulu zisetshenziswa njengama-ejenti elaphayo, okuvamise ukuba ngu-5 kuya ku-15% yenani leresin. I-Acid anhydride isetshenziswa njenge-ejenti yokwelapha, engu-0.1 kuya ku-3% yenani leresin. I-Polybasic adhesive isetshenziswa njengenzuzo yokwelapha. I-epoxy resin isikwe ku-1: 1 mol cal. I-703 isetshenziswa njenge-ejenti yokwelapha, engasetshenziswa ngokuya nge-1.0.4 (isilinganiso sesisindo)
