ʻO ka Polybutadiene i hoʻopaʻa ʻia (EPB)
ʻO EPB kahi hui epoxy i hoʻokomo ʻia i loko o ke kaulahao molekala PB, nona nā pono o ke kūpaʻa ʻaila, ke kūpaʻa ʻelemakule, ka mālamalama maikaʻi, ka hana haʻahaʻa haʻahaʻa, a pēlā aku. ʻO ka hui epoxy i loko o ke kaulahao molekala he hui reactive, hiki ke ho'ōla ʻia me nā ʻano isocyanates a me nā mea hoʻōla epoxy.
Loaʻa i ka polymer i hoʻōla ʻia nā waiwai kino a me nā kemika maikaʻi, ka ikaika hoʻopili maikaʻi loa i ka metala a me ke aniani a me nā mea ʻē aʻe ʻaʻole metala, nā waiwai dielectric maikaʻi, ka helu shrinkage haʻahaʻa, ka paʻakikī kiʻekiʻe, kūpaʻa i ka alkali a me ka hapa nui o ka leo, hiki ke hoʻomaikaʻi nui i nā waiwai mechanical, ka ikaika hoʻopili a me ke kūpaʻa wela o nā mea polyurethane.
Hoʻomaikaʻi nā hui polar i nā waiwai hoʻopaʻa o ka huahana me nā mea metala a me nā mea ʻole metala; Hiki ke hoʻohana ʻia i nā mea hoʻopili, nā mea hoʻopaʻa, nā uhi, ka hoʻoikaika ʻana o ka epoxy resin, nā elastomers polyurethane, a pēlā aku.
Hoʻopaʻa ʻia i loko o 50kg/pahu, 170kg/pahu, ʻO ka manawa mālama he 1 makahiki.
Nā kuhikuhi palekana:
Pono e mālama ʻia ma kahi anuanu, maloʻo a me ka ea. ʻO ke kūlana maikaʻi loa ma waena o -20 ~ 38℃. ʻO ke ola o ka papa he 12 mau mahina, inā pau, e hoʻohana mau ʻia inā kū i ke kūlana ma o ka hoʻāʻo hou ʻana. I ka wā e lawe ai, pono e pale i ka ua a me ka lā. Mai hoʻohuihui me ka oxidizer ikaika.
