Sula i-Epoxy Resin

Incazelo yokukhiqiza

Sula i-epoxy resin zihlukaniswe ngamamodeli we-E44/6101 kanye ne-E51/128, okungeye-epoxy resin matrix kanye nemikhiqizo eqediwe. Imikhiqizo yabo ayikwazi ukusetshenziswa ngokuqondile ukwenza imikhiqizo eqediwe, futhi eminye imikhiqizo esekelayo idinga ukwengezwa.

I-ejenti yokwelapha iyisengezo esibalulekile futhi ngeke selapheke ngaphandle kwayo.

I-resin enevelu ye-epoxy emaphakathi (0.25~0.45) izosetshenziswa njengento enamathelayo; I-resin enevelu ephezulu ye-epoxy (>0.40) esetshenziswa njenge-castable; I-resin enenani eliphansi le-epoxy (<0.25) izosetshenziswa njengokwemboza.

Impahla kanye Isicelo

1. Ngokuphathelene nokugqoka, i-epoxy resin ilandisa ingxenye enkulu ekusetshenzisweni kokugqoka. Ingenziwa ibe izinhlobo ezinezici ezihlukene kanye nokusetshenziswa, ikakhulukazi esetshenziswa njengopende wokunqanda ukugqwala, i-metal primer kanye nopende wokuvikela.

2. Mayelana ne-adhesive. Sula i-Epoxy resin ngezinto ezihlukahlukene zensimbi ezifana ne-aluminium, insimbi, insimbi, ithusi; Izinto ezingezona ezensimbi njengengilazi, ukhuni, ukhonkolo, njll. Futhi amapulasitiki e-thermosetting, njenge-phenolic, amino, i-polyester engagcwalisiwe, njll., anezakhiwo ezinhle kakhulu zokubopha, ngakho abizwa ngokuthi ama-adhesives jikelele. I-epoxy adhesive iwuhlobo olubalulekile lokunamathela kwesakhiwo.

3. Mayelana nezinto zikagesi nezikagesi. I-Epoxy resin isetshenziswe kabanzi ekufakeni nasekupakisheni izinto zikagesi ezinamandla aphezulu naphansi, izinjini nezingxenye ze-elekthronikhi ngenxa yokusebenza kwayo okuphezulu kwe-insulation, amandla aphezulu esakhiwo, ukusebenza kahle kokuvala kanye nezinye izinzuzo eziningi eziyingqayizivele.

4. Kobunjiniyela bepulasitiki nezinto eziyinhlanganisela. Amapulasitiki wobunjiniyela be-epoxy ikakhulukazi afaka amapulasitiki okubumba ama-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.

5. Ngokwezinto zokwakha zobunjiniyela bomphakathi, i-epoxy resin isetshenziswa 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 zokuhlanganisa.

Inqubo Yokukhiqiza

Ukufundisa

Sula i-Epoxy resin ayivamisile ukusetshenziswa iyodwa. Ngokuvamile, kusetshenziswa izinto ezisizayo ezinjengama-ejenti okwelapha asetshenziswayo. Izingxube ze-amine ezisezingeni eliphezulu zisetshenziswa njengama-ejenti elaphayo, okungama-5-15% yenani le-resin. I-Acid anhydride isetshenziswa njenge-ejenti yokwelapha, engu-0.1-3% yenani le-resin. I-Polyamine isetshenziswa njenge-ejenti yokwelapha, enesilinganiso se-molar esingu-1:1 ku-epoxy resin. I-7.3 isetshenziswa njenge-ejenti yokwelapha, engasetshenziswa ngesilinganiso se-1: 0.4 (isilinganiso sesisindo).

Ukubukeka Nomehluko

I-E44 ine-viscosity ephakeme, i-E51 ine-viscosity ephansi kanye ne-fluidity enhle.

Inani le-epoxy le-epoxy resin libhekisela enanini lezinto ezisekelwe epoxy eziqukethwe kuwo wonke ama-100g eresin.

I-E44 imele ukuthi inani le-epoxy elimaphakathi ngu-44/100, futhi inani le-epoxy ngu-(0.41~0.47)

I-E44 inesisindo samangqamuzana aphezulu kanye nenani elincane le-hydroxyl ku-molecule, evumelana nokwandisa amandla okubopha kanye nesivinini sokuphulukisa, futhi ifanele ukusetshenziswa njengezinto zokumboza nezinamatheliso.

I-E51 imele inani le-epoxy elimaphakathi 51/100, futhi inani le-epoxy ngu-(0.48~0.54)

Imikhiqizo ye-E51 epoxy resin inenani eliphakeme le-epoxy, i-viscosity ephansi, umbala okhanyayo, ubulukhuni obuphezulu kanye nokumelana okuhle kwamakhemikhali. Zifanele imboni ye-elekthronikhi futhi zisetshenziswa kabanzi njengezinamatheliso, izimbotshana ezingancibilikiyo, izinto zokuzilinganisa phansi nezinto ezifakwayo.

Njengopende ophansi we-epoxy, ukuze kuthuthukiswe ukusebenza kukonke, kuyadingeka ukwengeza izithasiselo ezifanele, izincibilikisi, ama-leveling ejenti, izisabalalisi, ama-defoam, njll. Isilinganiso se-primer esivamile (2:1,4,15:1)

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)
