Umyalo:

I-BMI, njenge-resin matrix enhle yokukhiqiza izinto zokwakha ezingamelana nokushisa kanye nezinto zokwenza ugesi u-H noma u-F, iya isetshenziswa kabanzi kwezindiza, i-aerospace, amandla kagesi, i-elekthronikhi, ikhompyutha, ukuxhumana, izitimela, ujantshi, ukwakhiwa kanye neminye imikhakha yezimboni . Ifaka ikakhulukazi:

1.Upende wokukhulelwa okumelana nokushisa okuphezulu (okususelwa ku-solvent-free ne-solvent-free), upende owenziwe nge-enameled, i-laminate, i-weft tape yamahhala, i-mica tape, i-electronic clad laminate, ipulasitiki ebunjiwe, i-epoxy modified F ~ H powder enamathela, izingxenye zokulingisa, njll. .; 2.I-resin ye-matrix eyinhlanganisela esezingeni eliphakeme, i-aerospace, izinto zokwakha zezindiza, i-carbon fiber ukushisa okuphezulu izingxenye ezingahambisani nokwakhiwa, ibhodi lesifunda eliphrintiwe eliphakeme nezinye izinto zokusebenza, njll;

3. Ukuqinisa isishintshi, i-ejenti ye-crosslinking ne-ejenti entsha yokwelapha injoloba yamaplastiki wobunjiniyela afana ne-PP, PA, ABS, APC, PVC, PBT, EPDM, PMMA, njll.

4.Gqoka izinto zokumelana: isondo lokugaya idayimane, isondo lokugaya umthwalo osindayo, ibhuleki lephedi, izinga lokushisa eliphakeme elinamathela, izinto kazibuthe, njll.

5. Ezinye izinto zamakhemikhali omanyolo (synthetic ammonia) imishini nemishini yokugcoba okungenawo uwoyela, izinto zokufaka uphawu ezinamandla nezimile nezinye izinkambu eziningi zobuchwepheshe.

Ukumelana nokushisa

I-BMI inokumelana okuhle nokushisa ngenxa yendandatho yayo ye-benzene, i-heideocycle ye-imide kanye nobukhulu obuphezulu be-crosslinking. I-TG yayo ngokuvamile inkulu kune-250 ℃, futhi ibanga layo lokushisa kwensizakalo lingaba ngu-177 ℃ ~ 232 ℃. Ku-aliphatic BMI, i-ethylenediamine iyona ezinze kakhulu. Ngokwanda kwenombolo ye-methylene, izinga lokushisa lokubola lokushisa lokuqala (TD) lizokwehla. I-TD ye-BMI enamakha ngokuvamile iphakeme kunaleyo ye-aliphatic BMI, kanti i-TD ye-2,4-diaminobenzene iphakeme kunezinye izinhlobo. Ngaphezu kwalokho, kukhona ubudlelwano obusondelene phakathi kwe-TD nokuxinana kokuxhumanisa. Ebangeni elithile, i-TD iyanda ngokwanda kokuqina kwe-crosslinking.

Ukuncibilika

I-BMI esetshenziswa ngokujwayelekile ingaqedwa kuma-reagents we-organic njenge-acetone ne-chloroform, futhi ingaqedwa kuma-solvents aqinile, anobuthi futhi abizayo njenge-dimethylformamide (DMF) ne-N-methylpyrrolidone (NMP). Lokhu kungenxa ye-polarity yamangqamuzana nokulinganisa kwesakhiwo kwe-BMI.

Impahla yemishini

Ukuphendula okwelaphayo kwe-resin ye-BMI kungokwengeza i-polymerization, engenayo imikhiqizo ephansi yamangqamuzana futhi kulula ukuyilawula. Ngenxa yokwakheka okuhlangene kanye nokukhubazeka okumbalwa, i-BMI inamandla aphezulu nemodyuli. Kodwa-ke, ngenxa yobuningi be-crosslinking density kanye nokuqina kwamaketanga okuqina komkhiqizo ophulukisiwe, i-BML iveza ukuqina okukhulu, okubonakala ngamandla amabi omthelela, ukunwebeka okuphansi ngesikhathi sekhefu nokuqina okuphansi kokuqina g1c (<5J / m2). Ubulukhuni obumpofu buyisithiyo esikhulu se-BMI ukuzivumelanisa nezidingo zobuchwepheshe obuphakeme nokwandisa izinkambu ezintsha zohlelo lokusebenza, ngakho-ke indlela yokwenza ubulukhuni isibe obunye bobuchwepheshe obuyinhloko bokunquma ukusetshenziswa nokuthuthukiswa kwe-BMI. Ngaphezu kwalokho, i-BMI inezakhiwo zikagesi ezinhle kakhulu, ukumelana namakhemikhali kanye nokumelana nemisebe.
