Cellulose ana ana vana inoshandiswa zvakanyanya mukuunganidzwa senge manhamba nekuda kwezvivakwa zvavo zvakasarudzika uye zvinoshanda. Vanosimudzira vhiza yejasi, vachipa yakavandudzwa mashandiro emidziyo uye kupera-chigadzirwa kuita. Kunzwisisa basa ravo sezvinoita manhamba kunoda kubviswa mumanyorerwo avo emanyorerwo, zvidimbu zvine mimwe manhamba mune zvekutara, pamwe nemhedzisiro yavo pane rheology uye mafirimu ekuumbwa.
1. Molecular chimiro:
Cellulose anaiters ana vana vanobva kumasero, chisikwa chinoitika phermer inowanikwa mumadziro echitokisi. Kuburikidza nemakemikari kugadziridzwa, sekutsausa, hydroxyprupropropylation, kana carboxymethylation, cellaulose ana anaitwe. Izvi zvinoshandurwa kuunza mapoka anoshanda kune iyo cellulose backbone, inoshandura iyo solubility uye yekudyidzana ine sol sol.
2. Solubility uye kuzvimba:
Cellulose ana ana vana vane madhigirii akasiyana ekugadzirisa mumvura uye organic sol soles, zvichienderana nerudzi uye degree rekutsiva. Mune majasi ejasi, cellaulose etana kazhinji anozvimba mumvura-yakavakirwa masisitimu, achiumba mazwi ekugadzirisa kana gels. Uku kuzvimba kunoita kuti avo vakabatikana mhedzisiro, sezvo iyo yakazvimba polymer cheni inopinda uye kukanganisa kuyerera kweiyo solvent.
3. Hydrogen kusungwa:
Kubatira kweHydrogen kunoita basa rakakosha mukuwirirana pakati pevaCellulose anahers uye mamorekuru emvura kana zvimwe zvikamu mukubika. Mapoka eHydroxyl aripo muCellulose anaiters anogona kuumba hydrogen zvisungo nemamolekyudhi emvura, kusimudzira kuumbwa nekuzvimba. Pamusoro pezvo, hydrogen yekubatanidza inobata kutaurirana pakati pevaCellulose vaither uye vamwe polymers kana masimba muhukama hwekugadzira, vachipesvedzera zvivakwa.
4. Rheology shanduko:
Cellulose ana ana anaita senhau nekuchinja zvivakwa zvetsiva zvemakonzo. Ivo vanopa masheya ekutetepa-kutetepa, zvichireva kuti viscosity inoderera pasi pekushushikana kweshoko panguva yekunyorera asi inozodzikira pakushushikana. Ichi chivakwa chinotungamira kusununguka kwekushandisa apo uchipa vhiza yakakwana kudzivirira kusekerera kana kudonha kwekucheka.
5. Film formation uye kugadzikana:
Munguva yekuomesa uye kuporesa maitiro, cellulose ana ana anomirira kuumbwa kweyunifomu uye firimu rakagadzikana. Sezvo iyo solvent inoputika, iyo cellulose ether molecules inoenderana uye nyanza kuti ugadzire chimiro chefirimu. Iyi firimu inopa simba rekusimba, kudenha kune iyo substrate, uye kuramba kune zvinhu zvakatipoteredza zvakadai sekusiga uye abrasion.
6. Kuenderana uye Synergy:
Cellulose eter inoratidza kuenderana nehuwandu hwakawanda hwekubatanidza zvikamu, kusanganisira zvisungo, pigments, uye zvinowedzera. Ivo vanogona synergistically kudyidzana nevamwe vatatu kana rheology modifiers, vachiwedzera kushanda kwavo mubatanidzwa. Nekutsvagisa kusarudzwa uye kusanganisa cellulose ana vana nevamwe vanowedzera, vagadziri vanogona kuwana zvaunoda rheological zvivakwa uye maitiro ekuita mumakotari.
7..
Cellulose anaiters inofarirwa mumakonzo mafambiro nekuda kweiyo biodergradability yavo, inovandudzwa sosi, uye kutevedzera zvinodiwa nekuchengetedza kwezvakatipoteredza uye nehutano kuchengeteka. Sevatengi pamwe nevatengi masangano anowedzera kuwedzeredza kudiwa uye eco-hushamwari zvigadzirwa, kushandiswa kwe cellulose ana anaitle kunoenderana nezvinangwa izvi.
Cellulose eriners inoshanda seyakafanana nejasion nekukasira maitiro avo, mashura uye zvimwe zvikamu, zvimamwe kugadzirwa, mafirimu ekuumba, uye zvakanakira, uye zvakanakira zvakatipamhama. Chisikwa chavo chose uye chaunga chikuru chinovaita vanowedzera vanowedzera mujasi, vachiparira kuita basa rekuita, aesthetics, uye kusimba.
