Gukoresha selile ya polyanionic (PAC) mumazi ashingiye kumazi

Cellulose ya polyanionic (PAC) ikoreshwa cyane cyane kugabanya igihombo cyamazi, kongerera imbaraga ubukana hamwe na rheologiya mugucukura amazi. Uru rupapuro rusobanura muri make ibipimo ngenderwaho by’umubiri n’imiti bya PAC, nk'ubukonje, rheologiya, uburinganire busimburana, ubuziranenge n’ikigereranyo cy’imyunyu ngugu, hamwe n’ibipimo byerekana mu gucukura amazi.
Imiterere idasanzwe ya PAC ituma yerekana imikorere myiza mumazi meza, amazi yumunyu, amazi yinyanja namazi yumunyu wuzuye. Iyo ikoreshejwe nk'igabanya rya filtrate mu gucukura amazi, PAC ifite ubushobozi bwo kugenzura neza gutakaza amazi, kandi cake y'ibyondo ikozwe ni nto kandi ikomeye. Nka viscosifier, irashobora kunoza byihuse ubwiza bugaragara, ububobere bwa plastike nimbaraga zogosha imbaraga zogucukura amazi, no kunoza no kugenzura imvugo yicyondo. Ibikoresho byo gusaba bifitanye isano rya hafi nibimenyetso bifatika nibicuruzwa byabo.

1. Ubukonje bwa PAC nuburyo bukoreshwa mugutobora amazi

Ubukonje bwa PAC nicyo kiranga igisubizo cya colloidal cyakozwe nyuma yo gushonga mumazi. Imyitwarire ya rheologiya yumuti wa PAC igira uruhare runini mubikorwa byayo. Ubukonje bwa PAC bufitanye isano nurwego rwa polymerisiyasi, igisubizo cyibisubizo hamwe nubushyuhe. Muri rusange, urwego rwo hejuru rwa polymerisiyonike, niko ubwiza bwiyongera; Ubukonje bwiyongereye hamwe no kwiyongera kwa PAC; Igisubizo cyijimye kigabanuka hamwe no kwiyongera kwubushyuhe. Ubusanzwe NDJ-79 cyangwa Brookfield viscometer ikoreshwa mugupima ubukonje mubipimo bifatika na chimique byibicuruzwa bya PAC. Ubukonje bwibicuruzwa bya PAC bugenzurwa ukurikije ibisabwa. Iyo PAC ikoreshwa nka tackifier cyangwa rheologiya igenzura, ubusanzwe PAC irakenewe cyane (icyitegererezo cyibicuruzwa ni pac-hv, pac-r, nibindi). Iyo PAC ikoreshwa cyane nkigabanya igihombo cyamazi kandi nticyongere ubwiza bwamazi yo gucukura cyangwa guhindura rheologiya yamazi yo gucukura ikoreshwa, harasabwa ibicuruzwa bya PAC bitagaragara neza (ibicuruzwa byibicuruzwa ni pac-lv na pac-l).
Mubikorwa bifatika, imvugo yamazi yo gucukura ifitanye isano na: (1) ubushobozi bwamazi yo gucukura gutwara ibiti byo gucukura no gusukura iriba; (2) Imbaraga z'abazungu; (3) Ingaruka zifatika ku rukuta rw'imigozi; (4) Gukoresha igishushanyo mbonera cyo gucukura. Imvugo ya dring fluid isanzwe igeragezwa na viscometer yihuta 6: 600 rpm, 300 rpm, 200 rpm, 100 rpm na 6 rpm. 3 Ibisomwa bya RPM bikoreshwa mukubara ububobere bugaragara, ububobere bwa plastike, imbaraga zogosha imbaraga nimbaraga zogosha zihamye, byerekana imvugo ya PAC mumazi yo gucukura. Muri icyo gihe kimwe, uko ubukonje bwa PAC buri hejuru, niko bigaragara cyane ubwiza bwikaraga hamwe nubusembwa bwa plastike, hamwe nimbaraga nini yo gukata hamwe nimbaraga zihamye.
Byongeye kandi, hari ubwoko bwinshi bwamazi ashingiye kumazi (nk'amazi meza yo gutobora amazi meza, kuvura imiti yo kuvura imiti, kuvura imiti ya calcium yo kuvura, amazi yo gucukura saline, amazi yo mu nyanja, n'ibindi), bityo rheologiya ya PAC muburyo butandukanye sisitemu yo gucukura amazi aratandukanye. Kuri sisitemu yihariye yo gucukura, hashobora kubaho gutandukana kwinshi mugusuzuma ingaruka kumazi yo gutobora amazi gusa uhereye kumurongo wijimye wa PAC. Kurugero, muri sisitemu yo gucukura amazi yo mu nyanja, kubera umunyu mwinshi, nubwo ibicuruzwa bifite ubukonje bwinshi, urugero rwo gusimbuza ibicuruzwa bizatuma umunyu muke urwanya ibicuruzwa, bikaviramo kutagira ubukana bwiyongera. y'ibicuruzwa mugikorwa cyo gukoresha, bikavamo ubukonje buke bugaragara, ubukonje buke bwa plastike hamwe nimbaraga nke zogosha zamazi yo gucukura, bikavamo ubushobozi buke bwamazi yo gucukura gutwara ibiti, bishobora gutuma umuntu akomera cyane manza.

2.Icyiciro cyo gusimbuza uburinganire bwa PAC nuburyo bukoreshwa mugucukura amazi

Urwego rwo gusimbuza ibicuruzwa bya PAC mubisanzwe birenze cyangwa bingana na 0.9. Ariko, kubera ibikenerwa bitandukanye byabakora inganda zitandukanye, urwego rwo gusimbuza ibicuruzwa bya PAC ruratandukanye. Mu myaka yashize, amasosiyete akora ibijyanye na peteroli yakomeje kunoza ibisabwa mu bikorwa by’ibicuruzwa bya PAC, kandi n’ibicuruzwa bya PAC bifite urwego rwo hejuru rwo gusimbuza biriyongera.
Impamyabumenyi yo gusimbuza hamwe nuburinganire bwa PAC bifitanye isano rya bugufi nu kigereranyo cyumunyu mwinshi, kurwanya umunyu no gutakaza ibicuruzwa. Mubisanzwe, urwego rwo hejuru rwo gusimbuza PAC, niko arirwo rusimburanya, kandi niko igereranyo cyumunyu mwinshi, kurwanya umunyu no kuyungurura ibicuruzwa.
Iyo PAC imaze gushonga mumashanyarazi akomeye ya electrolyte inorganic umunyu, ubwiza bwumuti buzagabanuka, bikavamo icyo bita ingaruka zumunyu. Iyoni nziza ionisiyoneri yumunyu na - coh2coo - Igikorwa cyitsinda rya H2O rya H2O rigabanya (cyangwa rikuraho) homoelectricity kumurongo wuruhande rwa molekile ya PAC. Bitewe n'imbaraga zidahagije zo kwanga amashanyarazi, urunigi rwa molekile ya PAC iragoramye kandi igahinduka, hamwe na hydrogène zimwe na zimwe zihuza iminyururu ya molekile ziracika, zangiza imiterere yumwanya wambere kandi zigabanya cyane ubwiza bwamazi.
Kurwanya umunyu wa PAC mubisanzwe bipimwa nigipimo cyumunyu mwinshi (SVR). Iyo SVR agaciro ari hejuru, PAC yerekana ituze ryiza. Mubisanzwe, urwego rwo hejuru rwo gusimbuza nuburyo bwiza bwo gusimburana, niko agaciro ka SVR niko hejuru.
Iyo PAC ikoreshwa nkigabanya rya filtrate, irashobora ionize mumurongo muremure wiminyururu myinshi mugutobora amazi. Amatsinda ya hydroxyl na ether ogisijeni mumurongo wacyo wa molekuline akora hydrogène ya hydrogène hamwe na ogisijeni hejuru yuturemangingo twinshi cyangwa gukora imikoranire ihuza na Al3 + kumurongo uhuza ibice byibumba, kugirango PAC ishobore kwerekanwa kubumba; Kuvomera amatsinda menshi ya sodium carboxylate yongerera firime hydrata hejuru yubutaka bwibumba, ikabuza kwegeranya ibice byibumba mo ibice binini bitewe no kugongana (kurinda kole), kandi ibice byinshi byibumba bizashyirwa kumurongo wa molekile ya PAC kuri icyarimwe kugirango ukore imiyoboro ivanze ikubiyemo sisitemu yose, kugirango tunonosore igiteranyo cyimiterere yibice byijimye, urinde ibirimo ibice byamazi yo gucukura no gukora cake yuzuye ibyondo, Kugabanya kuyungurura. Urwego rwo hejuru rwo gusimbuza ibicuruzwa bya PAC, niko ibintu byinshi biri muri sodium karubasi ya sodium, niko bigenda bihinduka kimwe cyo gusimbuza, hamwe na firime hydrata imwe, ibyo bigatuma imbaraga zo kurinda gel za PAC mu gucukura amazi, bityo rero bigaragara ingaruka zo kugabanuka kwamazi.

3. Isuku ya PAC no kuyikoresha mugutobora amazi

Niba sisitemu yo gucukura itandukanye, igipimo cyumuti wogutwara amazi hamwe nubuvuzi buratandukanye, bityo dosiye ya PAC muburyo butandukanye bwo gucukura irashobora kuba itandukanye. Niba igipimo cya PAC mumazi yo gutobora cyerekanwe kandi amazi yo gucukura afite rheologiya nziza no kugabanya kuyungurura, birashobora kugerwaho muguhindura ubuziranenge.
Mubihe bimwe, hejuru yubuziranenge bwa PAC, nibikorwa byiza. Nyamara, ubuziranenge bwa PAC nibikorwa byiza byibicuruzwa ntabwo byanze bikunze biri hejuru. Impirimbanyi hagati yimikorere nubuziranenge bigomba kugenwa ukurikije uko ibintu bimeze.

4. Gukoresha imikorere ya PAC antibacterial no kurengera ibidukikije mumazi yo gucukura

Mubihe bimwe na bimwe, mikorobe zimwe na zimwe zizatera PAC kubora, cyane cyane mugikorwa cya selile na pey amylase, bikaviramo kuvunika urunigi nyamukuru rwa PAC no gushiraho isukari igabanya, urugero rwa polymerisiyasi rugabanuka, kandi ubwiza bwigisubizo bukagabanuka. . Ubushobozi bwo kurwanya enzyme ya PAC buterwa ahanini nuburinganire bwa molekuline nuburinganire bwo gusimburwa. PAC hamwe nuburyo bwiza bwo gusimbuza kandi urwego rwo hejuru rwo gusimbuza rufite imikorere myiza yo kurwanya enzyme. Ni ukubera ko urunigi rwuruhande ruhujwe n ibisigazwa bya glucose bishobora kurinda enzyme kubora.
Urwego rwo gusimbuza PAC ruri hejuru cyane, bityo ibicuruzwa bifite imikorere myiza ya antibacterial kandi ntibizatanga impumuro ya putrid bitewe na fermentation ikoreshwa mubyukuri, ntabwo rero bikenewe kongeramo imiti idasanzwe, ifasha kubaka ahakorerwa.
Kubera ko PAC idafite uburozi kandi ntacyo itwaye, ntabwo ihumanya ibidukikije. Byongeye kandi, irashobora kubora mugihe cya mikorobe yihariye. Kubwibyo, biroroshye kuvura PAC mumazi yo gucukura imyanda, kandi ntabwo byangiza ibidukikije nyuma yo kuvurwa. Kubwibyo, PAC ninyongera nziza yo kurengera ibidukikije byongera amazi.
