ATPB Amino-terminated polybutadiene (ATPB)
He ʻōpala polibutadiene wai ka ATPB me nā hui amine ma nā wēlau ʻelua o ke kaulahao molekala. Ke hoʻohālikelike ʻia me nā hui hydroxyl, ʻoi aku ka wikiwiki o ka hopena ma waena o nā hui amine a me nā isocyanates, a ʻoi aku ka wikiwiki o ka hopena ma ka mahana o ka lumi. E hoʻohui i ka lawa. Hiki ke hoʻōla ʻia me ka mea hoʻōla isocyanate a i ʻole e hana me nā hui epoxy no ka hoʻōla ʻana.
Loaʻa i ka mea i hoʻōla ʻia ʻo ATPB ka insulation uila maikaʻi loa a me nā waiwai mechanical, ʻoi aku ka pale ʻana i ka waikawa a me ka alkali, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa haʻahaʻa.
Hoʻohana nui ʻia ʻo ATPB no nā mea hoʻopili, nā uhi, nā mea hoʻopili polyurethane potting, nā kaila polyurethane, nā elastomers polyurethane kūpaʻa haʻahaʻa, 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.
