Me pēhea te whiriwhiri i te kaiwhakaora tika mō te Hydroxyl-Terminated Polybutadiene (HTPB) CAS Nama 69102-90-5? Me whai mahi motuhake tō tono, ā, ko te whakautu kei runga i te taurite. Me paunatia e koe ngā whāinga miihini pēnei i ngā mea kume...

Ka wetekina e te octoate stannous (T-9) te hononga pai rawa atu mā te tere tere i te tauhohenga urethane, ka hangaia he whatunga polymer kiato ake, kia kaha ake hoki e piri pūmau ana ki ngā momo matūriki. Ko tōna ihirangi stannous teitei (≥27.8%) ka taea te...

Kei te huri haere a CTBN me HTPB i te hangarau piri. Ka hangaia e rāua he hononga e tu atu ana i te ahotea nui, i ngā huringa pāmahana, me ngā taiao uaua. He maha ngā wā ka pakaru ngā piri tuku iho i te pānga. Ka tukuna e ngā pūnaha rapa wai he pakari me te...

Kei te mahi koe i ngā wāhanga rapa e pupuhi ana, e pakaru ana, e pakaru wawe ana rānei? Me whakahaere tika te whakapūkara - ka puta he hapa i te kore taurite, ā, ahakoa te iti rawa o te 1% o te horapa o ngā matū whakaora ka arahi pea ki te...

Me whiwhi koe i te māka tika mō tō kaupapa. Ko te Fullerene C60 taumata-whakauru CAS Nama 99685-96-8 me te paura Fullerene C60 taumata-whakauru ka tukuna he parakore 99.9%, e whakanui ana i te nekehanga irahiko mā te 2.44 ngā wā i roto i ngā hikohiko. Ko te tikanga 99...

He iti te taumaha-ngota o ngā rapa wai tauhohe, ā, he rōpū pito tauhohe matū. Ka whakapai ake i te pakari, te ngāwari, me te piri ki ngā piripiri, ngā paninga, me ngā mea whakakotahi. Ko ngā momo matua ko te HTPB, CTBN, me te CTPB, ia mea he ...

Kei roto i te DDI (Dimeryl Diisocyanate) he pūtake waikawa dimer C36 me te iti o te paitini monomer. Kāore i rite ki te TDI kakara me te MDI, ko tōna hanganga aliphatic ngāwari ka puta he polyurethanes pumau UV, kore-kōwhai, me te hydrophobic. Ka whiriwhiria e ngā kaihanga D...

Me nui ake ngā pāmahana e hiahiatia ana mō te rapa wai kua whakawhāitihia ki te carboxyl (CTBN, CAS No. 25265-19-4) kia tauhohe ai ki ngā mowhiti epoxy. Ka piri tahi te rapa wai kua whakawhāitihia ki te amine (ATBN, CAS No. 68683-29-4) ki ngā whakapakeke epoxy i te pāmahana rūma...

Ka hangaia e ngā kaihanga te 99% Pyruvic aldehyde dimethyl acetal cas 6342-56-9 Methylglyoxal Dimethylacetal mā te whakapūtanga waikawa o te methylglyoxal me te methanol anhydrous i raro i te whakamaroketanga whakahaeretia. Ko tēnei ārai...

Ko ngā whakarewa toenga me ngā fullerene teitei ake e whakatau ana i ngā taumata parakore i roto i te parakore teitei 99.5% 99.9% 99.95% Fullerene C60 paura cas 99685-96-8. Ka whakarerekē ngā poke i te nekehanga irahiko i roto i ngā optoelectronics, ā, ka puta he paitini koiora rūpahu. Ko te tohu tika...

Ko te tauhohenga nucleophilic i waenga i ngā rōpū hydroxyl me ngā rōpū isocyanate ka hanga hononga urethane kaha i roto i ngā pūnaha here. Ko ngā whakatakotoranga e whakamahi ana i te Dimeryl Diisocyanate (DDI CAS NO. 68239-06-5) HTPB (Hydroxyl-terminated polibutadiene CAS 69102...

Ka taea e koe te whakakaha ngāwari i ngā kapia epoxy mā te whakamahi i te epoxidized hydroxyl-terminated polibutadiene (EHTPB). Ka hangaia e ngā tuara polibutadiene ngāwari ngā rohe iti e mimiti ana i te pūngao i roto i tō matrix. Ka āwhina ngā rōpū tauhohe takirua i te EHTPB ki te here i te covalen...
