Mirayiridzo:

Inonyanya kushandiswa kuchinjisa bismaleimide resin (BMI), iyo inogona kudzikisa zvakanyanya mutengo wekushandisa weBMI resin uye nekuvandudza mashandiro uye kugadziriswa kweBMI resin. Iko kuomarara, kupisa kupisa uye kuumba chivakwa cheBMI resin kwakagadziridzwa. Inogona kushandiswa kwe: materials magetsi ekuisa zvinhu, emhangura-akapfeka wedunhu mabhodhi, yakanyanya tembiricha inomisikidza pendi, inodzivirira pendi laminates, kuumba mapurasitiki, nezvimwewo. inonamira, nezvimwewo. ③ Aerospace zvivakwa zvemukati. Materials Anoshanda zvinhu. Seye antioxidant yerabha, kuwedzera 1-3% BBA murabha kunogona kuvandudza zvakanyanya kusagadzikana kwekukwegura kwerabha

Kurapa kinetics uye zvemagetsi zvimiro zve diallyl bisphenol yakagadziridzwa cyanate ester resin yakadzidzwa: Diallyl bisphenol A(DBA) yakashandiswa kugadzirisa cyanate ester resin (CE). Iyo inorapa kinetic parameter yeiyo yakagadziriswa resin system yakaverengerwa naFlynn madziro Ozawa nzira yekushandura uye Kissinger extremum nzira, zvichiteerana. Iyo michina zvivakwa uye zvine simba zvemagetsi zvimiro zveiyo yakaporeswa resin zvakadzidzwa. Mhedzisiro yacho yakaratidza kuti DBA yaive nemhedzisiro yekukonzeresa uye kuomarara kwecyanate ester resin, Iyo yekumisikidza simba yekurapa maitiro eakagadziriswa resin ane 5% DBA yaive diki (62.16 kJ / mol). Kana zvirimo zveDBA zvaive gumi muzana, simba rekurapa reresini yakaporeswa yaive 2.07 nguva yeiyo yakachena cyanate ester resin. Iyo modulus yekuchengetedza uye girazi shanduko tembiricha yeEC resin ine DBA yakadzikira

Diallyl bisphenol A(dabpa) yakashandiswa kugadzirisa iyo bismaleimide resin ine ether ketone mamiriro (ek-bmi). Iyo inorapa kinetics ye ek-bmi / dabpa system yakadzidzwa neyakajeka kusiyanisa scanning calorimetry, Fourier shandura infrared spectroscopy, Kissinger crane nzira uye tembiricha yekupisa mwero yekuwedzera nzira, Iyo michina zvivakwa, kutsemuka kuomarara uye kupisa kwemafuta kwe ek-bmi / dabpa system zvaive akadzidza. Mhedzisiro yacho yakaratidza kuti iyo yekurapa maitiro parameter ye ek-bmi / dabpa system yaive 165 ℃ × 2 H + 180 ℃ × 2 H + 238 ℃ × 4 h, mamiriro ekurapa mushure mawo aive 250 h × 5 h, iri pachena simba rekuita yaive 97.50 kJ / mol, iyo frequency factor yaive 2.22 × 107 s-1, uye reaction order yaive 0.9328, Iyo tensile simba uye kukotama simba ndeye 89.42 MPa uye 152 MPa, zvichiteerana, uye girazi rekuchinja tembiricha iri 278 ℃. Iyo ichiri inogona kuchengetedza yakanaka michina zvivakwa pa270 ℃. Iyo yakakosha kushushikana kusimba chinhu uye yakakosha strain simba kuburitsa mwero inogona kusvika 1.14 MPa · m0.5 uye 276.6 J / m2, zvichiteerana, kuratidza kwakanaka kutsemuka kuomarara, Iyo yekutanga yekuora tembiricha yeiyo system iri 412.95 ℃ (T5%), iyo yakawanda yekuchengetedza chiyero chiri 37.91% pa600 ℃ uye 32.17% pa900 ℃

Kurongedza: 200kg / dhiramu.

Kuchengetedza kwekuchengetedza: chitoro mune inotonhorera, yakaoma uye yakachena mweya yekuchengetera.
