Cellulose Acetate Butyrate ine zvivakwa zvakanakisa senge hunyoro kuramba, UV kuramba, kutonhora kutonhora, kuchinjika, kujeka, uye kuvharirwa kwemagetsi, uye inoenderana zvakanaka neresin uye yakakwira yekubikira mapurasitiki.Plastics, substrates, mafirimu, uye machira ane akasiyana zvivakwa anogona kugadzirwa zvinoenderana neyakasiyana yemukati yebutyryl.Inogona kuumbwa neextrusion, jekiseni kuumba, kuumbwa kwe rotary, kuvhuvhuta, nezvimwewo, kana nekufashaidza kupfapfaidza.Kuwedzera kune hydroxyl uye acetyl mapoka, cellulose acetate butyrate zvakare ine butyryl mapoka, uye zvimiro zvayo zvine chekuita nezviri mumapoka matatu anoshanda.Kunyungudika kwayo uye kusimba kwesimba kunowedzera nekuwedzera kweacetyl yemukati, uye kuenderana kwayo nemaplasticizers uye kuchinjika kwefirimu kunowedzera mukati mehumwe huwandu nekuderera kweacetyl content.Kuwedzera kweiyo hydroxyl yemukati kunogona kukurudzira kunyungudika kwayo mumapolar solvents.Kuwedzera kwezviri mukati meboka rebutyryl kunoguma nekudzikira kwedensity uye kuwedzera kweiyo dissolution range.
Kushandiswa kweCellulose Acetate Butyrate
Cellulose Acetate Butyrate inoshandiswa sechinhu chinoyeresa uye firimu-inogadzira zvinhu kugadzira kujeka kwakanyanya uye yakanaka yemamiriro ekunze kuramba epurasitiki substrates, mafirimu, uye akasiyana machira.Kuwedzera kwezviri mukati meboka rebutyryl kunoguma nekudzikira kwedensity uye kuwedzera kweiyo dissolution range.Iine 12% kusvika 15% acetyl mapoka uye 26% kusvika 29% butyryl mapoka.Transparent or opaque granular material, ine kuoma kwekugadzirwa uye yakanaka kutonhora kuramba.CAB inogona kushandiswa seyakagadzirwa kugadzirwa kwemafirimu substrates, aerial photography substrates, matete films, etc. Inogonawo kushandiswa semidziyo yekufambisa mapaipi, mibato yemidziyo, tambo, zviratidzo zvekunze, mabhokisi emidziyo nezvimwe. Uye zvakare, inogona zvakare kushandiswa seyakagadzirwa simbi yekugadzira machira anopeeka, machira ekudzivirira, anodzivirira mamiriro ekunze akakwira-magumo machira, uye mafibhi ekugadzira.
Hunhu hwe cellulose acetate butyrate
Cellulose acetate butyrate ine humwe hunhu hwakasarudzika hunoita kuti izivikanwe zvakanyanya mumashandisirwo.Chekutanga, ine yakanaka solubility uye adsorbability, uye inogona kusanganiswa zvizere nezvimwe zvinhu kuti iwane yakanakira kugadzirisa kuita.Kechipiri, cellulose acetate butyrate ine yakanaka kunyudza hunyoro uye inonyorovesa zvivakwa, izvo zvinogona kunyatso kuchengetedza hunyoro uye kugadzikana kwechinhu.Uye zvakare, ine zvakare yakanaka biocompatibility uye haizove nemhedzisiro yakaipa pamuviri wemunhu kana nharaunda.
Mazano ekushandiswa kwe cellulose acetate butyrate
Paunenge uchishandisa cellulose acetate butyrate, pane mamwe mazano uye matanho ekudzivirira anogona kubatsira kushandisa zvizere kuita kwayo.Chekutanga, cellulose acetate butyrate inofanira kuomeswa isati yashandiswa kuvandudza kunyungudika kwayo uye kugadzikana.Chechipiri, panguva yekugadzira, tembiricha yakakwira uye acidic mamiriro anofanirwa kudzivirirwa kudzivirira kuparara uye kuparara kwe cellulose.Uye zvakare, mirau yakakodzera uye mitemo inofanirwa kutevedzwa panguva yekushandiswa kuve nechokwadi chekuteerera uye kuchengetedzeka kwezvinhu.
Maitiro ekutonga kunaka kwe cellulose acetate butyrate
Hunhu hwe cellulose acetate butyrate hunogona kutongwa kubva kune zvinotevera zvinhu.Kutanga, inogona kutariswa nekutarisa kana chitarisiko chayo chakaoma uye chisina kusvibiswa kuri pachena.Kechipiri, kunyungudika kwayo uye kugadzikana kunogona kuyedzwa, uye yemhando yepamusoro cellulose acetate butyrate inofanirwa kuve nesolubility yakanaka uye kugadzikana kwekupisa.Pamusoro pezvo, zvinogoneka zvakare kutaura kune mukurumbira uye chitupa chimiro chevatengesi uye sarudza vane mukurumbira uye vanokwanisa vatengesi kuti vave nechokwadi chemhando yechigadzirwa uye kuvimbika.
Unilong Indasitiri yakazvipira kutsvagurudzo ye cellulose esters uye inopa pasi rose weCAB uye CAP zvigadzirwa.Inogona kuburitsa 4000 matani e cellulose acetate propionate (CAP) uye cellulose acetate butyrate (CAB) gore negore, uye inoshandiswa zvakanyanya mukugadzirisa zvinhu kunze kwenyika senge machira, kurongedza chikafu, matoyi evana, zvekurapa, nezvimwe.
