Umyalo:

Isetshenziselwa ukuguqulwa kwe-bismaleimide resin (BMI), enganciphisa kakhulu izindleko zokufaka isicelo se-BMI resin futhi ithuthukise ukusebenza nokusebenza kwe-resin ye-BMI. Ubulukhuni, ukumelana nokushisa nokubumba impahla ye-BMI resin yathuthukiswa. Ingasetshenziselwa ukwenza: materials izinto zokufaka kagesi, amabhodi wesekethe agqoke ithusi, upende wokukhulelwa ophakeme, ukuvikela amapende opende, ukubumba amapulasitiki, njll. Ar Gqoka izinto ezingamelana, isondo lokugaya idayimane, isondo lokugaya umthwalo osindayo, iphedi yokubopha, ukushisa okuphezulu ingcina, njll. materials Izinto zokwakha ze-Aerospace. Izinto zokusebenza ezisebenzayo. Njenge-antioxidant yerabha, ukufaka i-1-3% BBA kurabha kungathuthukisa kakhulu ukumelana nokuguga kwenjoloba

Ukuphulukisa i-kinetics nezakhiwo zemishini ye-diallyl bisphenol a resin cyanate ester resin kwafundwa: I-Diallyl bisphenol A(I-DBA) isetshenziselwe ukuguqula i-cyanate ester resin (CE). Amapharamitha we-kinetic aphulukisayo wesistimu ye-resin eguquliwe abalwa yindlela yokuguqula ye-Flynn wall Ozawa kanye nendlela yeKissinger extremum, ngokulandelana. Izici zemishini nezakhiwo ezinamandla zomshini we-resin ephulukisiwe zafundwa. Imiphumela ikhombise ukuthi i-DBA ibinomphumela osobala wokuthonya kanye nomphumela othinta amandla ku-cyanate ester resin, Amandla wokuvula okuphulukisa ukusabela kwe-resin eguquliwe equkethe i-5% DBA bekuncane kakhulu (62.16 kJ / mol). Lapho okuqukethwe kwe-DBA bekuyi-10%, amandla okuthelela we-resin ephulukisiwe bekuyizikhathi eziyi-2.07 zalapho kucutshungulwa i-cyanate ester resin. Imoduli yokugcina kanye nokushisa kwengilazi kokushintshwa kwe-CE resin equkethe i-DBA yehlile

I-Diallyl bisphenol A(dabpa) yasetshenziselwa ukuguqula i-resin ye-bismaleimide ngesakhiwo se-ether ketone (ek-bmi). I-kinetics ephulukisayo yohlelo lwe-ek-bmi / dabpa yafundwa ngamakhalori okuskena ashukumisayo ashukumisayo, i-Fourier eguqula ukubonwa kwe-infrared, indlela ye-Kissinger crane nezinga lokushisa lokushisa izinga le-extrapolation, Izici zemishini, ukuqina kokuqina nokuqina kokushisa kwesistimu ye-ek-bmi / dabpa wafunda. Imiphumela ikhombise ukuthi inqubo yokwelapha inqubo ye-ek-bmi / dabpa yayiyi-165 ℃ × 2 H + 180 ℃ × 2 H + 238 ℃ × 4 h, izimo zangemva kokwelashwa zaziyi-250 ℃ × 5 h, amandla abonakalayo okusebenza yayingu-97.50 kJ / mol, isici semvamisa sasingu-2.22 × 107 s-1, futhi ukuhleleka kokuphendula kwaba ngu-0.9328, Amandla aqine namandla okugoba angama-89.42 MPa nama-152 MPa, ngokulandelana, kanti ithempelesha yokuguquka kwengilazi ingu-278 ℃. Isengagcina izakhiwo ezinhle zomshini ku-260 ℃. Isici esibucayi sokuqina kwengcindezi kanye nesilinganiso sokukhishwa kwamandla esibucayi esibucayi singafinyelela ku-1.14 MPa · m0.5 no-276.6 J / m2, ngokulandelana, kukhombisa ukuqina okuhle kokuqhekeka, Ukushisa kokuqala kokubola kohlelo kungu-412.95 ℃ (T5%), ukugcinwa kwesisindo isilinganiso singama-37.91% kuma-600 ℃ kuthi ama-32.17% abe ngu-900 ℃

Ukupakisha: 200kg / isigubhu.

Izinyathelo zokuphepha zesitoreji: gcina endaweni yokugcina impahla epholile, eyomile nenomoya.

Amandla wonyaka: Amathani ayi-1000 / ngonyaka
