Maitiro ekupururudza emaserolose ana asherulose anosanganisira matanho akati wandei ekubvisa mheremellose manyorerwe kubva pazvinhu zvakabikwa uye nekukasira kuita cellulose. Cellulose ana ana makomputa akasiyana nemagetsi mune akasiyana maindasitiri, kusanganisira mishonga yemishonga, chikafu, zvinyorwa uye kuvaka. Maitiro ekupururudza akakosha kuti awane yakakwirira-mhando cellulose, iyo mbichana yekugadzirwa kwe cellulose ana vana. Izvi zvinotevera kutsanangurwa kwakadzama kweiyo cellulose ethy shamped maitiro:
1. Sarudzo yezvinhu:
Maitiro ekupururudza anotanga nesarudzo yemidziyo yakaomeswa ine cellulose. Zviitiko zvakajairika zvinosanganisira huni, machira, uye zvimwe zvirimwa fushi. Iko kusarudzwa kwezvinhu zvisina kugadzirwa zvinoenderana nezvinhu zvakaita se cellulose auto kuwanikwa, mutengo uye zvaunoda zvivakwa.
2. PUMP Kugadzira Maitiro:
Kune nzira dzakawanda dze cellulose kuputira, kunyanya kusanganisira makemikari kukanda uye mechancal kuputika.
3. Kemical Pulping:
Kraft kukanda: inosanganisira kurapa machipisi ehuni nemusanganiswa wesodium hydroxide uye sodium sulfide. Kuita uku kunopera lignin, kusiya kuseri kwemaseru cellulosic.
Sulfite Pulping: Uchishandisa Sulfuus Acid kana Bisulfite kuputsa Lignin muDeDESTOCK.
Organic solvent inoburitsa: uchishandisa organic sol solenic yakadai se ethanol kana methanol yekunyungudutsa lignin uye kuparadzaniswa cellulose machira.
4. Mechancal kukanda:
Dombo-rombo rombo rinobuda: rinosanganisira kugaya huni pakati pematombo kusvika pakuzvikamisa mafambiro.
Refiner Mechancal Pulping: Inoshandisa mashini masimba kuti aparadzanise mafuti nekunatsa matanda ehuni.
5. Kusvina:
Mushure mekuputika, cellulose inopa nzira yekujekesa kuti ibvise kusvibiswa uye ruvara. Chlorine, chlorine dioxide, hydrogen peroxide kana oksijeni inogona kushandiswa panguva yekubatanidza.
5 .. Cellulose Kugadziridzwa:
Mushure mekunatswa, cellulose inoshandurwa kuti igadzire cellulose ana vana. Nzira dzakajairika dzinosanganisira kuwedzerwa, itsirwo uye mamwe makemikari maitiro ekuchinja zvemuviri uye zvemakemikari zvivakwa zve cellulose.
6. Kuwedzera Kugadzirisa:
Alkalization: Kurapa cellulose neAlkali (kazhinji sodium hydroxide) kuburitsa Alkali cellulose.
Kuwedzera Eterafying Evhiziri: Alkaline Cellever Inotsvaga Vamiririri (vakadai saAlkyl mersides kana alkylene ollides) kusuma mapoka mapoka muCellulose chimiro.
Kusarerekera: Kusarerekera iyo yekuita musanganiswa wekupedza maitiro uye kuwana iyo yaunoda cellulose etera chigadzirwa.
7. Kugeza uye kuoma:
Iyo cellulose etera chigadzirwa chinogezwa kuti ubvise ne-zvigadzirwa uye kusachena. Mushure mekuchenesa, zvinyorwa zvacho zvakaomeswa kuti uwane izvo zvinodikanwa zvinyoro-nyoro.
8. Kukuya uye kuongorora:
Dry cellulose etana inogona kuvhiyiwa kuti uwane chaiwo sizi. Kusvetuka kunoshandiswa kupatsanura zvimedu zvehukuru hunodiwa.
8. Hunhu kutonga:
Hunhu hwekudzora matanho anoitwa kuti ave nechokwadi chekuti vana ma cellulose vaanosangana nematanho akatsanangurwa. Izvi zvinosanganisira kuyedzwa kwe viscosity, degree rekutsiva, zvinyoro-nyoro uye zvimwe zvikamu zvakakodzera.
9. Kukwikwidza uye kuendesa:
Iyo yekupedzisira cellulose etera chigadzirwa yakaiswa uye yakagoverwa kune dzakasiyana-siyana maindasitiri. Kurapa kwakakodzera kunovimbisa kuti mhando yechigadzirwa inochengetwa panguva yekuchengetedza uye yekufambisa.
Maitiro ekupururudza e cellulose genther akateedzana matanho anosanganisira kusarudzika kwekusarudza, kupururudza, cellaumose kushandurwa, kugeza, kuomesa, kuomesa uye kusakura uye kukanganisa Nhanho yega yega inokosheswa mukusarudza mhando uye zvivakwa zve cellulose ether yakagadzirwa, ichiita kuti iite yakakodzera kune huwandu hwakawanda hwekushandisa. Kufambira mberi kwehunyanzvi kunoenderera mberi nekuvandudza uye gadzirisa maitiro aya kuti uwedzere kushanda uye kusimba kwemherekukweretesa ether kugadzirwa.
