Yakasiyana-siyana mashandisirwo e cellulose uye mabudiro ayo

Cellulose is a macromolecular polysaccharide inoumbwa neglucose, inowanikwa muhuwandu hwakawanda mumiti yakasvibira uye zvipenyu zvemugungwa. Ndiyo yakanyanya kuparadzirwa uye yakakura kwazvo yakasikwa polymer zvinhu mune zvakasikwa. Iyo ine yakanaka biocompatibility, inovandudzwa uye Biodegradable uye zvimwe zvakanakira. Kuburikidza nephotosynthesis, zvidyarwa zvinogona kugadzira mazana emamiriyoni ematani e cellulose gore rega rega.

Cellulose Application Tarisiro

Yechinyakare cellulose yakashandiswa zvakanyanya nekuda kweiyo yega yemuviri uye makemikari zvimiro, nepo yakasikwa polymer material cellulose ine akasiyana ekushanda zvimiro mushure mekugadzirisa uye kugadzirisa, izvo zvinogona kusangana nezvinodiwa zvakasiyana zvemaindasitiri akasiyana. Iko kushanda kwekushandiswa kwe cellulose inoshanda zvinhu zvave zvechisikigo Mafambiro ekuvandudza uye tsvakiridzo hotspots dzepolymer zvinhu.

Cellulose derivatives inogadzirwa ne esterification kana etherification ye hydroxyl mapoka mu cellulose polymers ane makemikari reagents. Zvinoenderana nehunhu hwemagadzirirwo ezvigadzirwa, zvinobuda mu cellulose zvinogona kupatsanurwa muzvikamu zvitatu: cellulose ethers, cellulose esters, uye cellulose ether esters.

1. Cellulose ether

Cellulose ether izwi rinowanzoreva nhevedzano yezvinobva muselulosi zvinoumbwa nekuita kwealkali cellulose uye etherifying agent mune mamwe mamiriro. Cellulose ether imhando ye cellulose inotorwa nemhando dzakasiyana-siyana, yakakura application minda, hombe yekugadzira vhoriyamu uye yakakwirira yekutsvagisa kukosha. Kushandiswa kwaro kunosanganisira minda yakawanda yakadai seindasitiri, kurima, indasitiri yemakemikari yemazuva ese, kuchengetedza kwezvakatipoteredza, aerospace uye kudzivirira kwenyika.

Macellulose ethers anonyanya kushandiswa mukutengesa ndeaya: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose uye hydroxypropyl methylcellulose Cellulose nezvimwe.

2. Cellulose esters

Cellulose esters inoshandiswa zvakanyanya muminda yekudzivirira yenyika, indasitiri yemakemikari, biology, mushonga, kuvaka uye kunyange aerospace.

Ma cellulose esters anonyanya kushandiswa pakutengeserana ndeaya: cellulose nitrate, cellulose acetate, cellulose acetate butyrate uye cellulose xanthate.
3. Cellulose ether ester

Cellulose ether ester maester-ether akasanganiswa anobva kunze.

Nzvimbo yekushandisa

1. Pharmaceutical field

Cellulose ether uye ester derivatives inoshandiswa zvakanyanya mumushonga wekukora, excipient, kusunungurwa kwakasimba, kuburitswa kunodzorwa, kugadzira firimu uye zvimwe zvinangwa.

2. Coating munda

Cellulose esters inoita basa rakakosha mukuputira maapplication. Cellulose esters anoshandiswa mumabinders, akagadziridzwa resins kana pre-firimu zvinhu kupa machira ane akawanda akanakisa zvivakwa.

3. Membrane technology field

Cellulose uye zvinhu zvinobuda zvine zvakanakira kubuda kukuru, kuita kwakagadzikana, uye kudzokorodza. Kuburikidza ne layer-by-layer self-assembly, phase inversion nzira, electrospinning tekinoroji uye dzimwe nzira, membrane zvinhu zvine yakanakisa kupatsanura kuita zvinogona kugadzirwa. Mumunda we membrane tekinoroji inoshandiswa zvakanyanya.

4. Munda wekuvaka

Cellulose ethers ine high thermally reversible gel simba uye naizvozvo inobatsira sekuwedzera muzvikamu zvekuvaka, zvakadai sesimende-based tile adhesive additives.

5. Aerospace, motokari itsva dzemagetsi uye zvigadzirwa zvemagetsi zvepamusoro

Cellulose-based functional optoelectronic zvinhu zvinogona kushandiswa mune aerospace, itsva simba mota uye yepamusoro-yekupedzisira zvigadzirwa zvemagetsi.

6. Mimwe minda

Matambudziko uye Mhinduro muCellulose Application

Parizvino, cellulose ichine zvimwe zvikanganiso zvekuzvarwa. Nekuda kwehunhu hwechimiro chayo chakaunganidzwa, cellulose haigone kunyungudutswa uye inonetsa kunyungudika mune zvakajairwa zvinonyungudutsa, izvo zvinoderedza zvakanyanya kukura uye kushandiswa kwezvinhu zve cellulose. Zvakadai sekushaya kunyungudika mune zvakajairika zvinonyungudutsa, kushaya thermoplasticity, yakakwira hydrophilicity uye kushaikwa kweantibacterial properties.

Naizvozvo, dhizaini nekuvakwa kwezvinhu zvitsva zvinobva muselulosi ndiyo hwaro hwekushandiswa nemazvo kwe cellulose, uye kuvandudzwa kwehunyanzvi uye hunoshanda hwekugadzira cellulose dissolution tekinoroji inzira yakakosha uye vimbiso yekushandiswa nemazvo kwe cellulose.
