Polyanionic selile (PAC) mubyukuri ni polymer, cyane cyane ikomoka kuri selile.Uru ruganda rushimishije rusanga ibikorwa byinshi mubikorwa bitandukanye bitewe nimiterere yihariye n'imikorere.
Imiterere ya Cellulose ya Polyanionic:
Polyanionic selulose ikomoka kuri selile, ikaba ari imwe muri polymers karemano ku isi.Cellulose ni umurongo wa polysaccharide ugizwe no gusubiramo ibice bya glucose bihujwe hamwe na β (1 → 4) glycosidic.Ikora ibice byibanze byubaka urukuta rwibimera.Cellulose ya polyanionic yahinduwe selile, aho amwe mumatsinda ya hydroxyl yiminyururu ya selile asimbuzwa amatsinda ya anionic.Iri tsinda rya anionic akenshi ririmo karubisi (-COO⁻), sulfonate (-SO₃⁻), cyangwa fosifate (-PO₄⁻).Itangizwa ryaya matsinda anionic ritanga amazi hamwe nibindi bintu bitandukanye byifuzwa kuri polymer.
Synthesis ya Polyanionic Cellulose:
Cellulose ya polyanionic isanzwe ikomatanyirizwa hamwe hakoreshejwe imiti ya selile.Uburyo bumwe busanzwe burimo gukora selile hamwe na anhydride ivanze mubihe byihariye kugirango tumenye amatsinda ya anionic kumugongo wa selile.Imiterere yimyitwarire nubwoko bwa anhydride ikoreshwa igena urwego rwo gusimbuza (DS) yitsinda rya anionic kumurongo wa selile.Indangagaciro za DS zohejuru zitanga amazi menshi kandi akanonosora imikorere mubikorwa bimwe.
Ibyiza bya Cellulose ya Polyanionic:
Polyanionic selulose yerekana ibintu byinshi byihariye bituma ikwiranye nuburyo butandukanye bwa porogaramu:
Amazi meza: Gutangiza amatsinda ya anionic bitanga amazi ya selile ya polyanionic selile, bigatuma itanga ibisubizo bihamye cyangwa bikwirakwizwa mumazi.Uyu mutungo ni ingirakamaro cyane mubisabwa aho sisitemu ishingiye kumazi.
Guhindura umubyimba na Rheologiya: Cellulose ya polyanionic ikoreshwa cyane nkumubyimba woguhindura no guhindura rheologiya mubikorwa bitandukanye, harimo ibiryo, imiti, nibicuruzwa byita kumuntu.Itanga ubwiza kandi igatezimbere ituze hamwe nimiterere.
Kugenzura igihombo no kurwanya ibicurane: Mu nganda nko gucukura peteroli, selile ya polyanionic ikoreshwa mubushobozi bwayo bwo guhinduranya ibintu byahagaritswe no kugenzura igihombo cyamazi.Ifasha kubungabunga neza neza kandi ikongera imikorere yo gucukura.
Ubwuzuzanye: Cellulose ya polyanionic ihujwe nubwoko butandukanye bwimiti ninyongeramusaruro, bigatuma ihindagurika kugirango ikorwe mubikorwa bitandukanye.Irashobora kwinjizwa byoroshye muri sisitemu zitandukanye idateye ibibazo byo guhuza.
Biodegradabilite: Nubwo ihindagurika ryayo, selile ya polyanionic igumana biodegradabilite ya selile.Ibi biranga ni ngombwa mu kugabanya ingaruka z’ibidukikije, cyane cyane mu bikorwa aho kujugunya ari impungenge.
Gukoresha Cellulose ya Polyanionic:
Polyanionic selulose isanga porogaramu zitandukanye mubikorwa byinshi:
Inganda zikomoka kuri peteroli na gazi: Mu rwego rwa peteroli na gaze, PAC ikunze gukoreshwa nka viscosifier hamwe n’inyongeramusaruro yo gutakaza amazi mu gucukura amazi.Ifasha kubungabunga neza neza, kongera isuku, no kunoza imikorere.
Inganda z’ibiribwa: Mu nganda z’ibiribwa, PAC ikora nk'umubyimba, stabilisateur, hamwe n’inyandiko mu bicuruzwa bitandukanye nka sosi, imyambarire, ibikomoka ku mata, hamwe n’ubutayu.Itezimbere umunwa, ikongerera ituze, kandi ikarinda synereze mu gutegura ibiryo.
Imiti ya farumasi: Cellulose ya polyanionique ikoreshwa muburyo bwa farumasi nkibikoresho, bidahuza, kandi bigenzurwa mubisohoka muri tableti na capsules.Ifasha muri tablet cohesion, itanga imiti imwe irekurwa, kandi igateza imbere abarwayi.
Ibicuruzwa byita ku muntu ku giti cye: Mu bicuruzwa byita ku muntu ku giti cye, PAC ikoreshwa nkibyimbye, igahagarika, hamwe na stabilisateur ya emulsion mu bicuruzwa nka shampo, amavuta yo kwisiga, hamwe na cream.Yongera ibicuruzwa byijimye, itezimbere imiterere, kandi irinda gutandukana icyiciro.
Ibikoresho byubwubatsi: PAC ikoreshwa mubikorwa byubwubatsi nkumukozi wo gufata amazi, kubyimba, hamwe na rheologiya muguhindura sima nka minisiteri, grout, na plaster.Itezimbere imikorere, igabanya igihombo cyamazi, kandi ikongerera gukomera kubutaka.
Ingaruka ku bidukikije no Kuramba:
Mugihe polyanionic selile itanga inyungu zitandukanye mubijyanye nimikorere n'imikorere, ingaruka zayo kubidukikije nazo zigomba gutekerezwa.Nkibikomoka kuri selile, PAC igumana biodegradabilite ya polymer yababyeyi.Ibi bivuze ko mugihe gikwiye, selile ya polyanionic ishobora gusenywa na mikorobe ikabyara umusaruro utagira ingaruka, bikagira uruhare mukubungabunga ibidukikije.
Byongeye kandi, imiterere ishobora kuvugururwa ya selile nkibikoresho fatizo bya synthesis ya PAC itanga inyungu muburyo bwo kuboneka no kugabanya gushingira ku bicanwa biva mu kirere.Harimo gushyirwaho ingufu kugirango turusheho kunoza imikorere ya synthesis no kuzamura ibinyabuzima byangiza ibinyabuzima biva muri polyanionic selulose kugirango bigabanye ibidukikije.
polyanionic selulose ni polymer itandukanye ikomoka kuri selile, itanga ibintu byinshi mubikorwa bitandukanye.Imiterere yihariye, harimo gukemura amazi, ubushobozi bwo kubyimba, guhuza, hamwe na biodegradabilite, bituma iba ikintu ntagereranywa muburyo bwinshi.Nubwo gutanga inyungu zingenzi zikorwa, imbaraga zirakomeje kugirango selile ya polyanionic n'ibiyikomokaho bikorwe kandi bikoreshwe muburyo bwangiza ibidukikije, bityo binganize ibikenerwa ninganda nintego zirambye.
