ʻO ka Cellulose Acetate Butyrate, i hoʻopōkole ʻia ʻo CAB, he ʻano kemika (C6H10O5) n a he kaumaha molekala o miliona. He mea like ia me ka pauka paʻa i hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe organik, e like me ka waikawa acetic a me ka waikawa acetic. Hoʻonui kona solubility me ka hoʻonui ʻana o ka mahana. Loaʻa i ka Cellulose acetate butyrate kekahi kūpaʻa wela a ʻaʻole maʻalahi ka palaho ʻana i ka mahana o ka lumi.
Loaʻa i ka Cellulose Acetate Butyrate nā waiwai maikaʻi loa e like me ke kūpaʻa ʻana i ka makū, ke kūpaʻa ʻana o ka UV, ke kūpaʻa anu, ka maʻalahi, ka transparency, a me ka insulation uila, a he kūpono maikaʻi me nā resins a me nā plasticizers kiʻekiʻe. Hiki ke hana ʻia nā plastics, substrates, films, a me nā coatings me nā waiwai like ʻole e like me nā ʻano like ʻole o ka butyryl. Hiki ke hana ʻia ma o ka extrusion, injection molding, rotary molding, blow molding, etc., a i ʻole ma ka paila ʻana. Ma waho aʻe o nā hui hydroxyl a me acetyl, loaʻa pū ka cellulose acetate butyrate i nā hui butyryl, a pili kona mau waiwai i ka ʻike o nā hui hana ʻekolu. Hoʻonui kona kiko heheʻe a me ka ikaika tensile me ka hoʻonui ʻana o ka ʻike acetyl, a ʻo kona kūlike me nā plasticizers a me ka maʻalahi o ke kiʻiʻoniʻoni e hoʻonui i loko o kahi pae me ka emi ʻana o ka ʻike acetyl. ʻO ka hoʻonui ʻana o ka ʻike hydroxyl hiki ke hoʻolaha i kona solubility i nā solvents polar. ʻO ka hoʻonui ʻana o ka ʻike o nā hui butyryl e hopena i ka emi ʻana o ka density a me ka hoʻonui ʻana o ka pae dissolution.
Ka Hoʻohana ʻana o ka Cellulose Acetate Butyrate
Hoʻohana ʻia ʻo Cellulose Acetate Butyrate ma ke ʻano he mea hoʻohālikelike a me ka mea hana kiʻiʻoniʻoni no ka hana ʻana i nā substrates plastic transparency kiʻekiʻe a me ke kūpaʻa maikaʻi i ka wā, nā kiʻiʻoniʻoni, a me nā ʻano uhi like ʻole. ʻO ka hoʻonui ʻia ʻana o ka nui o nā hui butyryl e hopena i ka emi ʻana o ka density a me ka hoʻonui ʻana o ka laulā dissolution. Loaʻa iā 12% a 15% mau hui acetyl a me 26% a 29% mau hui butyryl. Mea granular transparency a opaque paha, me ke ʻano paʻa a me ke kūpaʻa anu maikaʻi. Hiki ke hoʻohana ʻia ʻo CAB ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā substrates kiʻiʻoniʻoni, nā substrates kiʻi kiʻi lewa, nā kiʻiʻoniʻoni lahilahi, a pēlā aku. Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka lawe ʻana i nā pipelines, nā lima hana, nā kaula, nā hōʻailona waho, nā pahu hana, a pēlā aku. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hana ʻana i nā uhi peelable, nā uhi insulation, nā uhi kiʻekiʻe kūpaʻa i ka wā, a me nā fiber artificial.
Nā ʻano o ka cellulose acetate butyrate
Loaʻa i ka cellulose acetate butyrate kekahi mau ʻano kūikawā e hoʻomaopopo nui ʻia ai i nā noi. ʻO ka mea mua, he solubility maikaʻi a me ka adsorbability, a hiki ke hui piha ʻia me nā mea ʻē aʻe e hoʻokō ai i ka hana hana kūpono. ʻO ka lua, loaʻa i ka cellulose acetate butyrate nā waiwai omo wai a me ka moisturizing, hiki ke mālama pono i ka makū a me ke kūpaʻa o ka mea. Eia kekahi, he biocompatibility maikaʻi hoʻi a ʻaʻohe hopena maikaʻi ʻole i ke kino kanaka a i ʻole ke kaiapuni.
Manaʻo no ka hoʻohana ʻana i ka cellulose acetate butyrate
I ka wā e hoʻohana ai i ka cellulose acetate butyrate, aia kekahi mau manaʻo a me nā hana palekana e hiki ke kōkua i ka hoʻohana piha ʻana i kāna hana. ʻO ka mea mua, pono e hoʻomaloʻo ʻia ka cellulose acetate butyrate ma mua o ka hoʻohana ʻana e hoʻomaikaʻi i kona solubility a me ke kūpaʻa. ʻO ka lua, i ka wā o ka hana ʻana, pono e pale ʻia ke kiʻekiʻe o ka mahana a me nā kūlana acidic e pale aku i ka palaho a me ka hōʻino ʻana o ka cellulose. Eia kekahi, pono e hahai ʻia nā lula a me nā lula pili i ka wā e hoʻohana ai e hōʻoia i ka hoʻokō a me ka palekana o nā mea.
Pehea e hoʻoholo ai i ka maikaʻi o ka cellulose acetate butyrate
Hiki ke hoʻoholo ʻia ke ʻano o ka cellulose acetate butyrate mai nā ʻano aʻe. ʻO ka mea mua, hiki ke hoʻoholo ʻia ma ka nānā ʻana inā maloʻo kona ʻano a ʻaʻohe haumia maopopo. ʻO ka lua, hiki ke hoʻāʻo ʻia kona solubility a me ke kūpaʻa, a pono i ka cellulose acetate butyrate kiʻekiʻe ke loaʻa ka solubility maikaʻi a me ke kūpaʻa wela. Eia kekahi, hiki nō hoʻi ke kuhikuhi i ka kaulana a me ke kūlana hōʻoia o nā mea hoʻolako a koho i nā mea hoʻolako kaulana a kūpono hoʻi e hōʻoia i ka maikaʻi a me ka hilinaʻi o ka huahana.
Ua kūpaʻa ʻo Unilong Industry i ka noiʻi ʻana i nā esters cellulose a he mea hoʻolako honua ia no nā huahana CAB a me CAP. Hiki iā ia ke hana i 4000 tons o ka cellulose acetate propionate (CAP) a me ka cellulose acetate butyrate (CAB) i kēlā me kēia makahiki, a hoʻohana nui ʻia i ka hana ʻana i nā huahana hoʻokuʻu aku e like me nā uhi, nā ʻōpala meaʻai, nā mea pāʻani a nā keiki, nā mea lapaʻau, a pēlā aku.
