Cellulose Acetate Butyrate, yakapfupikiswa seCAB, ine fomura yemakemikari (C6H10O5) n uye huremu hwemamorekuru hunosvika mamiriyoni. Chinhu chakaita sehupfu hwakasimba chinonyungudika mune zvimwe zvinonyungudutsa zve organic, zvakaita se acetic acid ne acetic acid. Kunyungudika kwayo kunowedzera nekupisa kuri kuwedzera. Cellulose acetate butyrate inewo kugadzikana kwekupisa uye haiore nyore pakupisa kwemumba.
Cellulose Acetate Butyrate ine hunhu hwakanaka hwakadai sekudzivirira hunyoro, kudzivirira UV, kudzivirira kutonhora, kuchinjika, kujeka, uye kuputira magetsi, uye inoenderana zvakanaka nemaresini uye mapurasitiki ane poindi yakawanda yekufashaira. Mapurasitiki, ma substrates, mafirimu, uye machira ane hunhu hwakasiyana anogona kugadzirwa zvichienderana nehuwandu hwakasiyana hwebutyryl. Inogona kugadzirwa ne extrusion, injection molding, rotary molding, blow molding, nezvimwewo, kana nekufashaira. Kuwedzera kune hydroxyl ne acetyl groups, cellulose acetate butyrate inewo butyryl groups, uye hunhu hwayo hwakabatana nehuwandu hwemapoka matatu anoshanda. Poindi yayo yekunyunguduka uye simba rekudhonza inowedzera nekuwedzera kwehuwandu hwe acetyl, uye kubatana kwayo ne plasticizers uye kuchinjika kwefirimu kunowedzera mukati meimwe nzvimbo nekudzikira kwehuwandu hwe acetyl. Kuwedzera kwehuwandu hwe hydroxyl kunogona kukurudzira kunyunguduka kwayo mu polar solvents. Kuwedzera kwehuwandu hwemapoka e butyryl kunoguma nekudzikira kwe density uye kuwedzera kwe dissolving range.
Kushandiswa kweCellulose Acetate Butyrate
Cellulose Acetate Butyrate inoshandiswa sechinhu chinoenzanisa uye chinogadzira firimu kuti igadzire kujeka kwakanyanya uye kudzivirira mamiriro ekunze, mafirimu, uye machira akasiyana-siyana. Kuwedzera kwehuwandu hwemaboka ebutyryl kunoguma nekudzikira kwehuwandu uye kuwedzera kwehuwandu hwekunyungudika. Ine 12% kusvika 15% yemapoka eacetyl uye 26% kusvika 29% yemapoka ebutyryl. Chinhu chakapfava kana chisina kujeka, chine magadzirirwo akaomarara uye chinodzivisa kutonhora zvakanaka. CAB inogona kushandiswa sezvinhu zvekugadzira mapurasitiki, mapurasitiki ekutora mifananidzo yemuchadenga, mafirimu matete, nezvimwewo. Inogona zvakare kushandiswa sezvinhu zvekutakura mapaipi, mibato yezvishandiso, tambo, zviratidzo zvekunze, mabhokisi ezvishandiso, nezvimwewo. Pamusoro pezvo, inogona zvakare kushandiswa sezvinhu zvekugadzira machira anobviswa, machira ekudzivirira, machira emhando yepamusoro anodzivirira mamiriro ekunze, uye machira ekugadzira.
Hunhu hwe cellulose acetate butyrate
Cellulose acetate butyrate ine hunhu hwakasiyana hunoita kuti izivikanwe zvakanyanya mukushandiswa kwayo. Chekutanga, ine kunyungudika kwakanaka uye inonyungudika, uye inogona kusanganiswa zvizere nezvimwe zvinhu kuti iwane kushanda kwakanaka kwekugadzirisa. Chechipiri, cellulose acetate butyrate ine hunhu hwakanaka hwekunwisa hunyoro uye hunyoro, izvo zvinogona kuchengetedza hunyoro uye kugadzikana kwezvinhu. Pamusoro pezvo, inewo hutano hwakanaka uye haizove nemigumisiro yakaipa pamuviri wemunhu kana nharaunda.
Mazano ekushandisa cellulose acetate butyrate
Pakushandisa cellulose acetate butyrate, pane mazano nematanho ekudzivirira anogona kubatsira kushandisa mashandiro ayo zvizere. Chekutanga, cellulose acetate butyrate inofanira kuomeswa isati yashandiswa kuti ivandudze kunyunguduka kwayo uye kugadzikana kwayo. Chechipiri, panguva yekugadzirisa, mamiriro ekupisa kwakanyanya uye acidity anofanira kudzivirirwa kudzivirira kuora nekuora kwecellulose. Pamusoro pezvo, mitemo yakakodzera inofanirwa kuteverwa panguva yekushandisa kuti ive nechokwadi chekuti zvinhu zvinotevedzera mitemo uye zvakachengeteka.
Maitiro ekutonga mhando ye cellulose acetate butyrate
Hunhu hwe cellulose acetate butyrate hunogona kutongwa kubva pazvinhu zvinotevera. Chekutanga, hunogona kuonekwa nekutarisa kana chitarisiko chayo chakaoma uye chisina tsvina yakajeka. Chechipiri, kunyunguduka kwayo uye kugadzikana kwayo zvinogona kuyedzwa, uye cellulose acetate butyrate yepamusoro inofanira kunge yakanyunguduka zvakanaka uye yakagadzikana pakupisa. Pamusoro pezvo, zvinokwanisikawo kutarisa mukurumbira uye mamiriro echitupa evatengesi uye kusarudza vatengesi vane mukurumbira uye vane hunyanzvi kuti uve nechokwadi chemhando uye kuvimbika kwechigadzirwa.
Unilong Industry yakazvipira kutsvagurudza maester ecellulose uye inopa pasi rose zvigadzirwa zveCAB neCAP. Inogona kugadzira matani 4000 ecellulose acetate propionate (CAP) uye cellulose acetate butyrate (CAB) pagore, uye inoshandiswa zvakanyanya mukugadzirisa zvigadzirwa zvekutengesera kunze kwenyika zvakaita sekuputira, kurongedza chikafu, matoyi evana, zvinhu zvekurapa, nezvimwewo.
