Polyanionic cellulose (PAC) zvirokwazvo ipolymer, kunyanya kubva kune cellulose.Iyi komputa inonakidza inowana yakakura maapplication mumaindasitiri akasiyana siyana nekuda kweiyo yakasarudzika zvivakwa uye kushanda kwayo.
Mamiriro ePolyanionic Cellulose:
Polyanionic cellulose inotorwa kubva ku cellulose, inova imwe yemapolymer echisikigo akawanda paPasi.Cellulose is linear polysaccharide inoumbwa nekudzokorora zvikamu zveglucose zvakabatanidzwa pamwe ne β (1 → 4) glycosidic bonds.Iyo inoumba chikamu chekutanga chechimiro chechirimwa masero madziro.Polyanionic cellulose inogadziriswa cellulose, uko mamwe emapoka ehydroxyl emaketani e cellulose anotsiviwa nemapoka eanionic.Aya mapoka eanionic anowanzo sanganisira carboxylate (-COO⁻), sulfonate (-SO₃⁻), kana phosphate (-PO₄⁻) mapoka.Kuunzwa kweaya mapoka eanionic kunopa kunyungudika kwemvura uye nezvimwe zvakasiyana siyana zvinodiwa kune iyo polymer.
Synthesis yePolyanionic Cellulose:
Polyanionic cellulose inowanzo gadzirwa kuburikidza nekugadziriswa kwekemikari ye cellulose.Imwe nzira yakajairika inosanganisira kuita cellulose neanhydride kompani pasi pemamiriro chaiwo kuunza mapoka eanionic pamusana we cellulose.Mamiriro ekuita uye rudzi rweanhydride inoshandiswa inosarudza chiyero chekutsiva (DS) yemapoka eanionic pacheni ye cellulose.Yakakwirira DS tsika inoguma mukunyungudika kukuru kwemvura uye nekunatsiridza mashandiro mune mamwe maapplication.
Zvinhu zvePolyanionic Cellulose:
Polyanionic cellulose inoratidza akati wandei akasiyana zvivakwa zvinoita kuti ive yakakodzera kune akasiyana siyana ekushandisa:
Kunyungudika kweMvura: Kuiswa kwemapoka eanionic kunopa kunyungudika kwemvura kune polyanionic cellulose, ichibvumira kuti igadzire mhinduro dzakagadzikana kana kupararira mumvura.Ichi chivakwa chinonyanya kubatsira mukushandisa uko mvura-yakavakirwa masisitimu inosarudzwa.
Kuwedzera uye Rheology Kugadziriswa: Polyanionic cellulose inoshandiswa zvakanyanya seyakakora mumiriri uye rheology modifier mumaindasitiri akasiyana, kusanganisira chikafu, mishonga, uye zvigadzirwa zvekuchengeta munhu.Inopa viscosity uye inovandudza kugadzikana nekugadzirwa kwemaitiro.
Flocculation uye Fluid Kurasika Kudzora: Mumaindasitiri akadai sekuchera oiri, polyanionic cellulose inoshandiswa pakugona kwayo kuyerera yakamiswa solids uye kudzora kurasikirwa kwemvura.Inobatsira kuchengetedza wellbore kugadzikana uye inowedzera kushanda zvakanaka kwekuchera.
Kugarisana: Polyanionic cellulose inoenderana nehuwandu hwakawanda hwemamwe makemikari uye ekuwedzera, zvichiita kuti ive inogoneka pakuumbwa mukushandisa kwakasiyana.Inogona kuiswa nyore nyore mumasisitimu akasiyana pasina kukonzera nyaya dzekuenderana.
Biodegradability: Pasinei nekugadziriswa kwayo, polyanionic cellulose inochengetedza iyo yekuzvarwa biodegradability ye cellulose.Hunhu uhu hwakakosha mukuderedza kukanganiswa kwezvakatipoteredza, kunyanya mumashandisirwo apo kuraswa kuri kunetseka.
Zvishandiso zvePolyanionic Cellulose:
Polyanionic cellulose inowana mashandisirwo akasiyana mumaindasitiri akawanda:
Indasitiri yeOiri neGasi: Muchikamu cheoiri negesi, PAC inowanzoshandiswa seviscosifier uye yekurasikirwa kwemvura yekudzora yekuwedzera mumvura yekuchera.Inobatsira kuchengetedza wellbore kugadzikana, inosimudzira kuchenesa gomba, uye inovandudza kuchera.
Indasitiri yeChikafu: Muindasitiri yechikafu, PAC inoshanda seyakakora mumiriri, inosimbisa, uye texturizer mune zvakasiyana zvigadzirwa zvakaita sesosi, madhirezi, zvigadzirwa zvemukaka, uye madhiri.Inovandudza muromo, inowedzera kugadzikana, uye inodzivirira syneresis mukugadzirwa kwezvokudya.
Mishonga: Polyanionic cellulose inoshandiswa mukugadzirwa kwemishonga sebhainda, disintegrant, uye inodzorwa kuburitsa mumiririri mumapiritsi nemakapisi.Inobatsira mukubatana kwehwendefa, inovimbisa kusunungurwa kwezvinodhaka zvakafanana, uye inovandudza kutevedza kwevarwere.
Personal Care Zvigadzirwa: Muzvigadzirwa zvekuchengeta munhu, PAC inoshandiswa seyakakora, inomisa mumiriri, uye emulsion stabilizer muzvigadzirwa zvakaita se shampoos, lotions, uye makirimu.Inowedzera viscosity yechigadzirwa, inovandudza manyorerwo, uye inodzivirira kuparadzaniswa kwechikamu.
Zvishandiso Zvekuvaka: PAC inoshandiswa muindasitiri yekuvaka sechinhu chekuchengetedza mvura, thickener, uye rheology modifier mune simende-based formulations sedhaka, grouts, uye plaster.Inovandudza kushanda, inoderedza kurasikirwa kwemvura, uye inowedzera kunamatira kune substrates.
Environmental Impact uye Sustainability:
Nepo polyanionic cellulose ichipa mabhenefiti akasiyana maererano nekuita uye kushanda, kukanganisa kwayo kwezvakatipoteredza kunofanirwawo kutariswa.Sekubva kune cellulose, PAC inochengetedza biodegradability yemubereki wayo polymer.Izvi zvinoreva kuti pasi pemamiriro akakodzera, polyanionic cellulose inogona kuputswa nema microorganisms kuita zvisingakuvadze byproducts, zvichibatsira mukuchengetedzeka kwezvakatipoteredza.
Zvakare, iyo inovandudzwa hunhu hweselulosi seyakagadziriswa yePAC synthesis inopa zvakanakira maererano nekuwanikwa kwezviwanikwa uye kuderedzwa kutsamira pamafuta efosi.Nhamburiko dziri kuenderera mberi nekunatsiridza maitiro ekugadzira uye kuwedzera biodegradability ye polyanionic cellulose derivatives kuti ideredze tsoka yavo yezvakatipoteredza.
polyanionic cellulose i polymer inoshanda zvakasiyana-siyana inotorwa kubva ku cellulose, inopa huwandu hwakasiyana hwekushandisa mumaindasitiri akasiyana siyana.Hunhu hwayo hwakasiyana, hunosanganisira kunyungudika kwemvura, kugona kukora, kuenderana, uye biodegradability, inoita kuti ive chinhu chakakosha mumigadziriso yakawanda.Ndichiri kupa mabhenefiti akakosha ekuita, kuedza kuri kuenderera mberi kuona kuti polyanionic cellulose uye zvinobva pairi zvinogadzirwa uye kushandiswa nenzira ine hanya kwezvakatipoteredza, nekudaro kuenzanisa zvinodiwa mumaindasitiri nezvinangwa zvekusimudzira.
