Umyalelo:

Isetyenziselwa ukuguqulwa kwe-bismaleimide resin (BMI), enokunciphisa kakhulu iindleko zesicelo se-BMI resin kunye nokuphucula ukusebenza kunye nokusebenza kwe-BMI resin. Ukuqina, ukumelana nobushushu kunye nokubumba ipropathi ye-BMI resin yaphuculwa. Ingasetyenziselwa: materials izinto zokwambathisa zombane, iibhodi zesekethe ezinxibe ubhedu, iqondo lobushushu eliphezulu lokumisa ipeyinti, i-laminates yepeyinti yokwambathisa, iiplastikhi zokubumba, njl. Ar Nxiba izinto ezinganyangekiyo, ivili lokusila ledayimani, ivili lokusila elinzima izinto ezincamathelayo, njl njl. Materials Izixhobo zokusebenza. Njenge-antioxidant yerabha, ukongeza i-1-3% ye-BBA kwirabha inokuphucula kakhulu ukuxhathisa kwerabha

Ukuphilisa i-kinetics kunye neepropathi zoomatshini be-diallyl bisphenol i-cyanate ester resin yafundwa: U-Diallyl bisphenol A(DBA) yayisetyenziselwa ukuguqula i-cyanate ester resin (CE). Ukunyanga iiparameter zekinetic zenkqubo ye-resin eguqulweyo kwabalwa indlela yokuguqula i-Flynn eludongeni lwendlela ye-Ozawa kunye nendlela ye-Kissinger extremum ngokulandelelana. Iipropathi zoomatshini kunye neempawu ezinamandla zomatshini we-resin ephilisiweyo zafundwa. Iziphumo zibonise ukuba i-DBA inefuthe elibonakalayo le-catalytic kunye nefuthe elibi kwi-resin ye-cyanate ester, Amandla okunyanga okusabela kwempendulo ye-resin eguqulweyo ene-5% ye-DBA yayiyeyona incinci (62.16 kJ / mol). Xa umxholo we-DBA wawuyi-10%, amandla eempembelelo e-resin ephilisiweyo ayengama-2.07 amaxesha elo ye-cyanate ester resin emsulwa. Imodyuli yokugcina kunye neqondo lokutshintsha kweglasi kwi-resin ye-CE equlathe i-DBA yehlile

U-Diallyl bisphenol A(dabpa) yayisetyenziselwa ukuguqula i-bismaleimide resin kunye ne-ether ketone structure (ek-bmi). Ukunyanga i-kinetics yenkqubo ye-ek-bmi / dabpa yafundwa ngovavanyo olunamandla lokwahlulahlula i-calorimetry, i-Fourier eguqula ukubonwa kwe-infrared, indlela ye-Kissinger crane kunye neendlela zokufudumeza iqondo lobushushu, Iipropathi zoomatshini, ukuqina kobukrelekrele kunye nokuzinza kobushushu kwenkqubo ye-ek-bmi / dabpa wafunda. Iziphumo zabonisa ukuba inkqubo yokuphilisa iiparameter ze-ek-bmi / dabpa system yayiyi-165 ℃ × 2 H + 180 ℃ × 2 H + 238 ℃ × 4 h, iimeko zasemva konyango zazingama-250 ℃ × 5 h, amandla okubonakalayo yayingu-97.50 kJ / mol, into ephindaphindayo yayiyi-2.22 × 107 s-1, kwaye i-odolo yokuphendula yayingu-0.9328, Amandla oqiniseko kunye namandla okugoba zii-89.42 MPa kunye ne-152 MPa ngokwahlukeneyo, kwaye iqondo lobushushu beglasi ngu-278 ℃. Isengagcina iipropathi ezilungileyo zoomatshini kwi-260 ℃. Eyona nto ibalulekileyo yoxinzelelo kunye namandla okuphuma kwamandla anokufikelela kwi-1.14 MPa · m0.5 kunye ne-276.6 J / m2, ngokwahlukeneyo, ebonisa ukuqina okuhle, Ubushushu bokuqala bokubola benkqubo yi-412.95 ℃ (T5%), ukugcinwa kobunzima ireyithi ngama-37.91% kuma-600℃ kunye nama-32.17% kuma-900 ℃

Ukupakisha: 200kg / igubu.

Amanyathelo okhuseleko: gcina kwindawo yokugcina izinto epholileyo, eyomileyo kunye nomoya.
