whakawhanake i tētahi putanga rerekē o te CTBN Carboxyl terminated butadiene nitrile rubber(CTBN) CAS 25265-19-4 Carboxyl-Terminated Butadiene-Acrylonitrile CAS 25265-19-4/68891-46-3
Ko te wai carboxyl-terminated butadiene acrylonitrile tētahi momo rapa wai he rōpū carboxyl tōna hei rōpū mahi, ā, ko tōna waehere ko CTBN, ka taea te whakamahi whānui i roto i ngā wāhi rererangi me ngā ahumahi ā-iwi. I te nuinga o te wā ka whakamahia te CTBN me te kapia somatotype. Ka taea e te CTBN he rōpū carboxyl-terminated hohe te tauhohe ki te kapia epoxy hei whakarei ake i te pakari.
Ka taea te whakamahi i te CTBN hei:
- Ngā piripiri, te here, te hiri, te rehu, te whakatō ki roto i ngā kohua (te rererangi, te motuka, te hiko/hikohiko, te ahumahi, te moana me ngā mahi hanga...)
- Ngā paninga (wairewa, paura, wai)
- He pakari te CTBN ki te kapia epoxy, ā, he tino ngāwari ki te whakarerekē i ngā kapia whakamahana pērā i te epoxy, te phenolic, te polyester unsaturated me ngā kapia photosensitive.
1. Whakarei ake i te pakari me te ngāwari o ngā kapia thermoset
2. Whakapai ake i te piri ki ngā papa e uaua ana ki te piri
3. Ka whakanui ake i te ātete ki te pānga me te pakaru
4. Whakapai ake i te pakari (ātete ki te ngenge)
5. Whakanuia ngā āhuatanga ā-pūkaha o te pāmahana iti
6. Kei te wātea te putanga FDA
1. He tino pai te CTBN hei whakarerekē i te ngāwari o ngā kapia whakatakoto wera pērā i te epoxy, te phenolic, te polyester unsaturated me ngā kapia photosensitive. Ka taea e ia te whakapai ake i te ātete ki te pakarukaru me te ātete ki te pakaru o te hua whakamutunga.
2. Ko te piripiri whakarewa i hangaia mai i te kapia epoxy i whakarerekētia e te CTBN (25% te nui o te acrylonitrile), he pakari, he ngāwari, he ātete hoki ki te ngenge. Ka taea te whakamahi hei here i ngā wāhanga o te papatahi, tae atu ki te karāhe waro me te whitiki terylene. Ka taea hoki te whakamahi i tēnei piripiri hei piripiri mimiti o ngā momo rauemi kakahu pēnei i te muka karāhe, te terylene me te muka waro.
3. Ka taea te whakamaroke i te piripiri i hangaia mai i te CTBN me te kapia epoxy i te pāmahana noa, ka taea te whakamahi hei here i ngā rauemi konumohe, ka eke ki te kaha piripiri teitei rawa atu i muri i ngā hāora 72. Ko te kaha tihorenga he 0.55MPa, ā, ko te kaha tapahi he 26.7MPa. Ko te rauemi hiri huānga hiko i hangaia mai i te epoxy whakarerekētia CTBN, e whakarei ake ana i te ātete pakaru, kāore he pakaru i muri i te 200 ngā wā hangarua i te pāmahana i waenga i te -55.0℃ ki te 150℃.
4. Ka taea te whakamahi i te CTBN hei piripiri i roto i te huri me te wira tapahi, he pai ake te ātete ki te karawarawa engari he pai ake te ātete ki te wai wera, me te pai hoki o te oro.
5. Ko te CTBN te mea nui e whakamahia ana hei here mō ngā pūwero rōkete totoka.
6. CTBN mō ngā Paninga (wairewa, paura, wai).
7. Me ētahi atu momo whakamahinga maha
I tākaihia ki te 50kg/pahu, 180kg/pahu, Ko te wā rokiroki he 1 tau.
Ngā tohutohu haumaru:
Me penapena ki te wāhi matao, maroke, ā, me te hauhautanga. Ko te pāmahana pai rawa atu kei waenganui i te -20 ~ 38℃. E 12 marama te roa o te rokiroki, ki te pau te wā, ka whakamahia tonu mēnā kua tutuki i te paerewa mā te whakamātautau anō. Me karo i te ua, i te rā rānei i te wā e kawe ana. Kaua e whakaranua ki te waikura kaha.
