0.Ijambo ry'ibanze

Polymer jelly ishingiye kumwirondoro ikoreshwa cyane mugukoresha amazi ya peteroli no kugenzura imyirondoro.Nyamara, mu myaka yashize, sisitemu yubushyuhe bukabije hamwe nubushyuhe bwo guhinduranya gel selulose ether gucomeka no kugenzura byahindutse buhoro buhoro ahantu h’ubushakashatsi bwo gucomeka amazi no kugenzura imyirondoro mu bigega bya peteroli biremereye..Imbaraga za gel ya selulose ether nimwe mubimenyetso byingenzi byerekana uburyo bwo gucomeka, ariko ntamahame amwe yuburyo bwo gupima imbaraga.Uburyo bukoreshwa muburyo bwo gusuzuma imbaraga za jelly, nkuburyo bwo kwitegereza - uburyo butaziguye kandi bwubukungu bwo gupima imbaraga za jelly, koresha imbonerahamwe yimbaraga za jelly kugirango umenye urwego rwimbaraga za gel zipimwa;uburyo bwo kuzunguruka - ibikoresho bisanzwe bikoreshwa ni Brookfield viscometer na rheometero, ubushyuhe bwikigereranyo cya viscometer ya Brookfield bugarukira muri 90°C;uburyo bwa vacuum inzira - iyo umwuka ukoreshwa kugirango ucike muri gel, gusoma cyane igipimo cyumuvuduko byerekana imbaraga za gel.Uburyo bwa gelling ya jelly ni ukongeramo umukozi uhuza umuti wa polymer.Umukozi uhuza ibice hamwe numuyoboro wa polymer uhujwe nububiko bwa chimique kugirango habeho imiterere yumurongo wa interineti, kandi icyiciro cyamazi kirazingizemo, kuburyo sisitemu yose itakaza amazi, hanyuma igahinduka Kuri jelly, iyi nzira ntishobora guhinduka kandi ni imiti ihinduka.Uburyo bwa gel ya selulose ether ni uko mubushyuhe buke, macromolecules ya selulose ether ikikijwe na molekile ntoya y'amazi binyuze mumigozi ya hydrogène kugirango bibe igisubizo cyamazi.Mugihe ubushyuhe bwigisubizo buzamutse, imigozi ya hydrogène irasenywa, hamwe na molekile nini ya selulose ether Leta aho molekile zihurira hamwe binyuze mumikoranire yitsinda rya hydrophobique kugirango ikore gel ni ihinduka ryumubiri.Nubwo uburyo bwa gelation bwibintu byombi butandukanye, isura ifite imiterere isa, ni ukuvuga ko imiterere yimodoka itagikoreshwa igizwe mumwanya-itatu.Niba uburyo bwo gusuzuma imbaraga za jelly bukwiranye no gusuzuma imbaraga za selulose ether gel ikeneye ubushakashatsi no kugenzura ubushakashatsi.Muri iyi nyandiko, uburyo butatu gakondo bukoreshwa mugusuzuma imbaraga za selile ya selile ya selile: uburyo bwo kwitegereza, uburyo bwo kuzunguruka hamwe nuburyo bwa vacuum bwa breakthrough, hamwe nuburyo bwiza bwo gutera imbaraga bushingiye kuriyi ngingo.

1. Igice cyubushakashatsi

1.1 Ibikoresho byingenzi byubushakashatsi

Amashanyarazi ahoraho yubushyuhe bwamazi, DZKW-S-6, Beijing Yongguangming Medical Instrument Co., Ltd.;ubushyuhe bwinshi hamwe na rheometero yumuvuduko mwinshi, MARS-III, Ubudage sosiyete HAAKE;kuzenguruka amazi menshi-pompe vacuum, SHB-III, Gongyi Red Instrument Equipment Co, Ltd.;sensor, DP1701-EL1D1G, Baoji nziza yo kugenzura ikoranabuhanga ryiza, Ltd.;sisitemu yo gushaka igitutu, Shandong Zhongshi Dashiyi Technology Co., Ltd.;umuyoboro w'amabara, mL 100, Tianjin Tianke Glass Instrument Manufacturing Co., Ltd.;icupa ryinshi ryikirahure cyikirahure, mL 120, Schott Glass Work, Ubudage;azote-isukuye cyane, Tianjin Gaochuang Baolan Gas Co., Ltd.

1.2 Ingero zigeragezwa no gutegura

Hydroxypropyl methylcellulose ether, 60RT400, Taian Ruitai Cellulose Co, Ltd.;gushonga 2g, 3g na 4g ya hydroxypropylmethylcellulose ether mumazi 50 mL ashyushye kuri 80℃, koga neza hanyuma wongereho 25℃y'amazi akonje ya mL 50, ingero zarashonze burundu kugirango habeho ibisubizo bya selile ya selile hamwe na 0.02g / mL, 0.03g / mL na 0.04g / mL.

1.3 Uburyo bwikigereranyo bwa selulose ether gel imbaraga zipimisha

(1) Yageragejwe nuburyo bwo kureba.Ubushobozi bwamacupa yikirahure yubushyuhe bukabije bwamacupa yikirahure akoreshwa mubigeragezo ni 120mL, nubunini bwumuti wa selulose ether ni 50mL.Shira ibisubizo bya selile yateguwe hamwe na 0.02g / mL, 0.03g / mL na 0.04g / mL mumacupa yikirahure yihanganira ubushyuhe bwinshi, uyihindure mubushyuhe butandukanye, hanyuma ugereranye ibitekerezo bitatu byavuzwe haruguru ukurikije code ya gel imbaraga Imbaraga za gelling ya selulose ether yamazi yumuti yageragejwe.

(2) Yageragejwe nuburyo bwo kuzunguruka.Igikoresho cyipimisha gikoreshwa murubu bushakashatsi ni ubushyuhe bwo hejuru hamwe na rheometero yumuvuduko mwinshi.Cellulose ether yamazi yumuti hamwe na concentration ya 2% iratoranijwe igashyirwa murugoma kugirango igerageze.Igipimo cyo gushyushya ni 5℃/ Iminota 10, igipimo cyogosha ni 50 s-1, naho igihe cyo gukora ni 1 min.Urwego rwo gushyushya ni 40～110℃.

(3) Byageragejwe nuburyo bwa vacuum.Huza imiyoboro ya colimetric irimo gel, fungura pompe ya vacuum, hanyuma usome gusoma cyane igipimo cyumuvuduko mugihe umwuka uciye muri gel.Buri cyitegererezo gikoreshwa inshuro eshatu kugirango ubone agaciro kagereranijwe.

(4) Gerageza ukoresheje igitutu cyiza.Dukurikije ihame ryuburyo bwa vacuum degre, twateje imbere ubu buryo bwo kugerageza kandi twakoresheje uburyo bwo gutera intambwe nziza.Huza imiyoboro ya colimetric irimo gel, hanyuma ukoreshe sisitemu yo gushaka igitutu kugirango ugerageze imbaraga za selulose ether gel.Ingano ya gel ikoreshwa mubigeragezo ni 50mL, ubushobozi bwumuyoboro wamabara ni 100mL, diameter yimbere ni 3cm, diameter yimbere yigitereko cyizunguruka cyinjijwe muri gel ni 1cm, naho ubujyakuzimu ni 3cm.Buhoro buhoro fungura kuri silindiri ya azote.Mugihe amakuru yerekana igitutu agabanutse gitunguranye kandi gikaze, fata ingingo nkuru nkimbaraga zisabwa kugirango ucike muri gel.Buri cyitegererezo gikoreshwa inshuro eshatu kugirango ubone impuzandengo.

2. Ibisubizo byubushakashatsi no kuganira

2.1 Ikoreshwa ryuburyo bwo kwitegereza kugirango ugerageze imbaraga za selulose ether

Nkigisubizo cyo gusuzuma imbaraga za gel ya selulose ether nukwitegereza, ugafata igisubizo cya selulose ether hamwe na 0,02 g / mL nkurugero, birashobora kumenyekana ko urwego rwimbaraga ari A mugihe ubushyuhe ari 65°C, n'imbaraga zitangira kwiyongera uko ubushyuhe bwiyongera, iyo ubushyuhe bugeze kuri 75℃, irerekana gel imiterere, urwego rwimbaraga ruhinduka kuva B kugeza D, kandi iyo ubushyuhe buzamutse bugera kuri 120℃, urwego rwimbaraga ruba F. Birashobora kugaragara ko ibisubizo byisuzuma ryubu buryo bwo gusuzuma byerekana gusa urwego rwimbaraga za gel, ariko ntirushobora gukoresha amakuru kugirango ugaragaze imbaraga zihariye za gel, ni ukuvuga ko yujuje ubuziranenge ariko sibyo ingano.Ibyiza byubu buryo nuko imikorere yoroshye kandi itangiza, kandi gel ifite imbaraga zisabwa irashobora kugenzurwa bihendutse nubu buryo.

2.2 Gukoresha uburyo bwo kuzunguruka kugirango ugerageze imbaraga za gel ya selile ether

Iyo igisubizo gishyushye kuri 80°C, ubwiza bwigisubizo ni 61 mPa·s, noneho ububobere bwiyongera vuba, kandi bugera ku giciro kinini cya 46 790 mPa·s kuri 100°C, hanyuma imbaraga ziragabanuka.Ibi ntabwo bihuye nibintu byagaragaye mbere yuko viscosity ya hydroxypropyl methylcellulose ether amazi yo mumazi atangira kwiyongera kuri 65°C, na geles bigaragara kuri 75°C n'imbaraga zikomeje kwiyongera.Impamvu yibi bintu ni uko gel yamenetse bitewe no kuzunguruka kwa rotor mugihe ugerageza imbaraga za gel ya selulose ether, bikavamo amakuru atariyo yimbaraga za gel mubushyuhe bukurikira.Kubwibyo, ubu buryo ntibukwiriye gusuzuma imbaraga za selile ya selile.

2.3 Gukoresha uburyo bwa vacuum bwa breakthrough kugirango ugerageze imbaraga za selulose ether

Ibisubizo byubushakashatsi bwa selulose ether gel imbaraga byasuzumwe nuburyo bwa vacuum.Ubu buryo ntabwo burimo kuzunguruka kwa rotor, bityo ikibazo cyo gukata colloidal no kumeneka biterwa no kuzunguruka kwa rotor birashobora kwirindwa.Duhereye kubisubizo byubushakashatsi byavuzwe haruguru, birashobora kugaragara ko ubu buryo bushobora kugereranya imbaraga za gel.Iyo ubushyuhe ari 100°C.Imbaraga za gel, ni ukuvuga, imipaka yo hejuru yimbaraga za gel zageragejwe nubu buryo ni 0.1 MPa.Muri ubu bushakashatsi, imbaraga za selulose ether gel irenze 0.1 MPa, ubwo buryo rero ntibukwiriye gusuzuma imbaraga za selulose ether gel.

2.4 Ikoreshwa ryuburyo bwiza bwokugerageza kugerageza imbaraga za gel ya selile

Uburyo bwiza bwumuvuduko bwakoreshejwe mugusuzuma ibisubizo byubushakashatsi bwa selulose ether gel imbaraga.Birashobora kugaragara ko ubu buryo bushobora gupima gel hamwe nimbaraga ziri hejuru ya 0.1 MPa.Sisitemu yo gukusanya amakuru yakoreshejwe mubigeragezo ituma ibisubizo byubushakashatsi birushaho kuba byiza kuruta imibare yo gusoma yakozwe muburyo bwa vacuum.

3. Umwanzuro

Imbaraga za gel ya selulose ether yerekanaga muri rusange kwiyongera hamwe nubushyuhe.Uburyo bwo kuzunguruka hamwe nuburyo bwa vacuum butambutse ntibukwiriye kumenya imbaraga za selulose ether gel.Uburyo bwo kwitegereza bushobora gupima gusa imbaraga za selulose ether gel, kandi uburyo bushya bwongewemo imbaraga zirashobora gupima imbaraga za selulose ether gel.
