Sechisikigo chepolymer musanganiswa, cellulose ine huwandu hwakasiyana hwekushandisa mukugadzira. Inonyanya kutorwa kubva kumadziro emadziro emiti uye ndeimwe yezvakanyanya kuwanda kwazvo pasi pano. Cellulose yakashandiswa zvakanyanya mukugadzira mapepa, machira, mapurasitiki, zvinhu zvekuvakisa, mishonga, chikafu uye mamwe maindasitiri nekuda kweiyo yakasarudzika mamorekuru maumbirwo, kushatisa kwezvakatipoteredza uye kunaka kwemuviri nemakemikari zvinhu.
1. Indasitiri yekugadzira mapepa
Iyo indasitiri yekugadzira mapepa ndiyo huru yekushandisa ndima ye cellulose. Mafibisi ekudyara anogona kugadzirwa kuita pulp mushure memuchina kana kurapwa kwemakemikari. Cellulose inopa simba uye kusimba sechinhu chikuru mukuita uku. Mukugadzira mapepa, kunyura kwemvura, kutsvedzerera uye kusimba kwepepa kunogona kudzorwa nekuwedzera makemikari ekuwedzera uye kushandisa akasiyana fiber musanganiswa. Kubuda kwepepa rakadzokororwa kunowedzera kusimbisa kusimba uye kudzokororwa kweselulosi, zvichiita kuti zvive zvakanyanya kubatsira mune zvakatipoteredza zvine hushamwari zvinhu.
2. Textile industry
Cellulose fibers (senge donje) inoshandiswa zvakanyanya mukugadzira machira seyakakosha zvinhu zveindasitiri yemachira. Cotton fibers ine inopfuura 90% cellulose, iyo inoita kuti ive yakapfava, hygroscopic, inofema uye zvimwe zvinhu zvakanakisa, zvakakodzera kugadzirwa kwemhando dzakasiyana dzembatya. Mumakore achangopfuura, cellulose fibers inogona kugadzirwa nekemikari kuti igadzire yakagadziridzwa cellulose fibers seviscose fibers uye modal fibers, ichiwedzera kuwedzera kushandiswa kweselulosi muindasitiri yemachira. Aya mafiber haasi chete akapfava uye akasununguka, asiwo ane yakanaka antibacterial uye biodegradable properties.
3. Bioplastics uye biodegradable zvinhu
Cellulose inogona kushandiswa kugadzira biodegradable mapurasitiki muindasitiri yepurasitiki, inova imwe yeakakosha nzira dzekutsvagisa dzekugadzirisa dambudziko re "kusvibiswa kuchena". Nekugadzirisa cellulose mu cellulose acetate kana cellulose ether, inogona kushandiswa kugadzira eco-friendly epurasitiki mafirimu, tableware, etc. Zvinhu izvi zvine simba rakasimba remakemikari uye zvinhu zvemuviri, uye zviri nyore kukanganisa mumamiriro echisikigo, kuderedza kukanganisa kwe tsvina yepurasitiki pane ecological environment.
4. Zvinhu zvekuvaka
Muindasitiri yekuvaka, cellulose inoshandiswa zvakanyanya kugadzira fiber simende mabhodhi, fiber yakasimbisa gypsum board uye thermal insulation zvinhu. Kubatanidza cellulose fiber nezvimwe zvinhu zvinogona kukwidziridza kupikisa kwavo, kusimba kwesimba, uye kunatsiridza kupisa kwemafuta uye kuvharisa inzwi. Semuyenzaniso, cellulose thermal insulation material ndeye zvakatipoteredza ine hushamwari hwekupisa kupisa. Nekuisa jekiseni cellulose poda kana cellulose zvimedu mumadziro echivako, inogona kunyatso kuvharira uye kuderedza ruzha, uye hunhu hwayo hwechipembenene hunodzivirira hunoita kuti huwedzere kushandiswa mukuvaka.
5. Chikafu neindasitiri yemishonga
Cellulose derivatives senge carboxymethyl cellulose (CMC) uye methyl cellulose (MC) zvakare ine zvakakosha mashandisirwo mumaindasitiri ezvekudya nemishonga. Carboxymethyl cellulose inoshandiswa zvakanyanya seyakakora, stabilizer uye emulsifier muchikafu, nepo methyl cellulose ichiwanzo shandiswa se disintegrant mumapiritsi nekuda kwekunamira kwayo kwakanaka uye biocompatibility. Uye zvakare, cellulose inogona zvakare kuwedzerwa kuchikafu sekudya fiber kubatsira vanhu kuvandudza intestinal hutano.
6. Cosmetics industry
Cellulose inowanzoshandiswa seyakakora uye inodzikamisa muzvizoro. Semuenzaniso, yakajairwa carboxymethyl cellulose uye microcrystalline cellulose inogona kuwedzera viscosity uye kugadzikana kwezvizoro uye kudzivirira stratification yezvigadzirwa. Mukuwedzera, kusvibiswa uye kusina-chepfu ye cellulose inoita kuti ive yakakodzera kushandiswa mukuchenesa zvigadzirwa, zvigadzirwa zvekuchengetedza ganda uye makeup.
7. Zvinhu zvakatipoteredza uye sefa zvinhu
Nekuda kweiyo porous chimiro uye yakanaka adsorption ye cellulose, iri kuwedzera kushandiswa musefa zvinhu. Cellulose membranes uye cellulose nanofibers anoshandiswa mukusefa kwemhepo, kurapwa kwemvura uye kugadzirwa kwetsvina yeindasitiri. Cellulose sefa zvinhu hazvigone chete kubvisa zvakamiswa zvimedu, asiwo adsorb zvinhu zvinokuvadza, zvine zvakanakira kushanda kwakanyanya uye kuchengetedza kwezvakatipoteredza. Pamusoro pezvo, iyo tsvakiridzo yekushandisa ye cellulose nanofibers inoita kuti ive nehukuru hwekugona mune ramangwana kusefa uye maindasitiri ekuchengetedza kwezvakatipoteredza.
8. Simba remunda
Cellulose biomass zvakare yakakwezva kutarisisa kwakawanda mumunda wesimba. Cellulose inogona kugadzira simba rinogoneka senge bioethanol uye biodiesel kuburikidza ne biodegradation uye kuvirisa. Kuenzaniswa nepetrochemical simba, izvo zvinopisa zvigadzirwa zvebiomass simba zvine hushamwari zvakatipoteredza uye zvinoenderana nepfungwa yekusimudzira. Tekinoroji yekugadzira ye cellulose biofuel iri kuvandudza zvishoma nezvishoma, ichipa mikana mitsva yesimba rakachena mune ramangwana.
9. Kushandiswa kwenanotechnology
Cellulose nanofibers (CNF) kufambira mberi kwakakosha mukutsvagisa cellulose mumakore achangopfuura. Nekuda kwesimba ravo rakakwirira, kuderera kwehudhi uye yakanaka biocompatibility, ivo vanoshandiswa zvakanyanya mumhando dzakasiyana siyana dzakaumbwa. Kuwedzerwa kwe cellulose nanofibers kunogona kuvandudza zvakanyanya mechanical properties ye composite zvinhu, uye zvichienzaniswa nemamwe nanomaterials, cellulose nanofibers inogona kudzokororwa uye biodegradable, saka vane ruzivo rwakakura mumagetsi emagetsi, sensors, mishonga yekurapa uye yakakwirira-kushanda zvinhu.
10. Kudhinda uye inkjet teknolojia
Mukudhinda uye inkjet tekinoroji, ma cellulose anotorwa anoshandiswa kuvandudza fluidity uye adsorption yeingi, zvichiita kuti kudhinda kuwedzere kufanana. Mune inkjet yekudhinda ingi, cellulose inogona kuita kuti mavara ave akazara uye akajeka. Pamusoro pezvo, kujeka uye kusimba kwe cellulose kunogona kuvandudza kunaka kwebepa rakadhindwa uye kuderedza kupararira kweinki, nekudaro kugadzira zvigadzirwa zvakadhindwa zvemhando yepamusoro.
Sechinhu chinovandudzwa uye chinoshatisa chepolymer zvinhu, cellulose yave chimwe chezvinhu zvakakosha mukugadzira kwemazuva ano. Kushandiswa kwayo kwakakura munzvimbo dzakasiyana-siyana kunoratidza kusiyana kwayo uye kuchengetedza kwezvakatipoteredza, uye inosimudzira shanduko yakasvibirira yemaindasitiri mazhinji. Mune ramangwana, nekuenderera mberi kwesainzi uye tekinoroji uye kubudirira kwe cellulose nanotechnology, kushandiswa kwe cellulose kuchave kwakasiyana.
