ʻO ka Cellulose Acetate Butyrate, i hoʻopau ʻia ʻo CAB, loaʻa ke ʻano kemika (C6H10O5) n a me ke kaumaha molekala o nā miliona.He pauda paʻa e like me ka mea hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe organik, e like me ka acetic acid a me ka acetic acid.Piʻi ka solubility me ka piʻi ʻana o ka mahana.Loaʻa i ka cellulose acetate butyrate kekahi ʻano paʻa wela a ʻaʻole hiki ke hoʻoheheʻe ʻia ma ka lumi wela.
Loaʻa i ka Cellulose Acetate Butyrate nā waiwai maikaʻi e like me ke kūpaʻa ʻana o ka wai, ka pale ʻana o UV, ke kūpaʻa anuanu, ka maʻalahi, ka ʻike, a me ka insulation uila, a he kūpono maikaʻi me nā resins a me nā plasticizers paila kiʻekiʻe.Hiki ke hana ʻia nā plastic, substrates, nā kiʻiʻoniʻoni, a me nā uhi me nā waiwai like ʻole e like me ka ʻokoʻa o ka butyryl.Hiki ke hana ʻia e ka extrusion, injection molding, rotary molding, blow molding, etc., a i ʻole ma ka paila ʻana.Ma waho aʻe o nā pūʻulu hydroxyl a me acetyl, cellulose acetate butyrate kekahi pūʻulu butyryl, a ua pili kona mau waiwai i ka ʻike o nā hui hana ʻekolu.Hoʻonui ʻia kona helu heheʻe a me ka ikaika tensile me ka hoʻonui ʻana i ka ʻike acetyl, a me kona kūlike me nā plasticizers a me ka maʻalahi o ka kiʻiʻoniʻoni e hoʻonui i loko o kahi ʻano me ka emi ʻana o ka ʻike acetyl.ʻO ka hoʻonui ʻana i ka ʻike hydroxyl hiki ke hoʻoikaika i kona solubility i nā solvents polar.ʻO ka hoʻonui ʻana i ka ʻike o nā pūʻulu butyryl ka hopena i ka emi ʻana o ka density a me ka hoʻonui ʻana i ka pae hoʻoheheʻe.
Hoʻohana i ka Cellulose Acetate Butyrate
Hoʻohana ʻia ʻo Cellulose Acetate Butyrate ma ke ʻano he mea hoʻokalakupua a me ka mea hana kiʻiʻoniʻoni no ka hana ʻana i ke aniani kiʻekiʻe a me ka maikaʻi o ka wā e pale ai i nā substrate plastic, nā kiʻiʻoniʻoni, a me nā ʻano uhi like ʻole.ʻO ka hoʻonui ʻana i ka ʻike o nā pūʻulu butyryl ka hopena i ka emi ʻana o ka density a me ka hoʻonui ʻana i ka pae hoʻoheheʻe.Loaʻa iā 12% a 15% mau pūʻulu acetyl a me 26% a 29% mau pūʻulu butyryl.ʻO nā mea kikoʻī a opaque paha, me ke ʻano paʻakikī a me ke kūpaʻa anu.Hiki ke hoʻohana ʻia ʻo CAB ma ke ʻano he kumu no ka hoʻomākaukau ʻana i nā substrates kiʻiʻoniʻoni, nā kiʻi kiʻi ea, nā kiʻi ʻoniʻoni lahilahi, a me nā mea ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hana ʻana i nā peelable coatings, insulation coatings, weather resistant high-end coatings, a me nā fiber artificial.
Nā hiʻohiʻona o ka cellulose acetate butyrate
Loaʻa i ka cellulose acetate butyrate kekahi mau hiʻohiʻona kūʻokoʻa i ʻike nui ʻia i nā noi.ʻO ka mea mua, loaʻa iā ia ka solubility maikaʻi a me ka adsorbability, a hiki ke hui pū ʻia me nā mea ʻē aʻe e hoʻokō ai i ka hana hoʻoponopono kūpono.ʻO ka lua, ʻo ka cellulose acetate butyrate ka maikaʻi o ka moisture absorption a me ka moisturizing waiwai, hiki ke mālama pono i ka haʻahaʻa a me ke kūpaʻa o ka mea.Eia kekahi, loaʻa iā ia ka biocompatibility maikaʻi a ʻaʻole e loaʻa nā hopena maikaʻi ʻole i ke kino kanaka a i ʻole ke kaiapuni.
Manaʻo no ka hoʻohana ʻana i ka cellulose acetate butyrate
Ke hoʻohana nei i ka cellulose acetate butyrate, aia kekahi mau ʻōlelo aʻoaʻo a me ka mālama ʻana 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 paʻa.ʻO ka lua, i ka wā o ka hana ʻana, pono e pale ʻia nā kūlana kiʻekiʻe a me ka acidic e pale i ka decomposition a me ka degradation o cellulose.Eia kekahi, pono e hahai ʻia nā lula pili a me nā lula 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 ka maikaʻi o ka cellulose acetate butyrate mai nā ʻano aʻe.ʻO ka mea mua, hiki ke hoʻoholo ʻia ma ka nānā ʻana inā ua maloʻo kona helehelena a ʻaʻohe o nā haumia maopopo.ʻO ka lua, hiki ke hoʻāʻo ʻia kona solubility a me kona kūpaʻa, a ʻo ka cellulose acetate butyrate kiʻekiʻe kiʻekiʻe e loaʻa i ka solubility maikaʻi a me ka paʻa wela.Eia hou, hiki ke kuhikuhi i ke kūlana kaulana a me ke kūlana hōʻoia o nā mea hoʻolako a koho i nā mea hoʻolako kaulana a kūpono e hōʻoia i ka maikaʻi o ka huahana a me ka hilinaʻi.
Hana ʻia ʻo Unilong Industry i ka noiʻi ʻana i nā esters cellulose a he mea hāʻawi honua i nā huahana CAB a me CAP.Hiki iā ia ke hana i ka 4000 tons o cellulose acetate propionate (CAP) a me cellulose acetate butyrate (CAB) i kēlā me kēia makahiki, a hoʻohana nui ʻia i ka hana ʻana i nā huahana e hoʻokuʻu aku e like me ka uhi, ka meaʻai meaʻai, nā mea pāʻani a nā keiki, nā lāʻau lapaʻau, etc.
