HPMC Hydroxypropyl methyl selulose nigipimo cya sima nikihe?
Amashanyarazi adafite amazi, ibiranga biterwa nuburemere bukurikira bwibikoresho fatizo bikozwe: beto 30-340, ubwubatsi bwubwubatsi bwamatafari yamatafari 40-50, lignin fibre 20-24, calcium ikora 4-6, hydroxypropyl methyl selulose 7-9, ifu ya karubone ya silikoni 40-45, ifu ya calcium hydroxide 10-4, ifu yumujyi wa sulfate 5-4 carboxymethyl Base ya krahisi 20-24, ibikoresho byahinduwe nanotehnologiya ifu ya karubone 4-6, amazi 600-650; Amashanyarazi adashobora gukoreshwa n’amazi y’iki gicuruzwa afite ubushyuhe bukabije, kurwanya umuriro neza, guhuza bikomeye n’urukuta, imbaraga zo kwikomeretsa, imikorere idahwitse, kurwanya gusaza neza, kurengera ibidukikije neza, kutagira amazi meza, kutavunika, kwirinda kugwa. Uyu munsi tuzavuga kubyerekeranye na viscosity ya hydroxypropyl methyl selulose igisubizo cyamazi byose mubice ki? Reka rwose twige.
1. 2. 3. Iyo ibintu byinshi biri muri selile ya selile, niko ubwinshi bwibisubizo byigisubizo, bityo rero mugushyira mubikorwa gusaba twakagombye kwitondera umubare ukwiye wo kwishyiriraho, gukumira kwishyiriraho ni byinshi cyane, kandi bigira ingaruka kuburyo butaziguye kubiranga sima ya beto na sima; 4. Kimwe na byinshi mubisubizo, viscosity nayo izagabanuka hamwe no kwiyongera kwubushyuhe, hiyongereyeho nibiri muri selile ya selile, niko ingaruka mbi zubushyuhe; Mubyongeyeho, ingaruka zifatika nazo ziratandukanye ukurikije ubwinshi bwamazi akoreshwa muri sima epoxy.
Hydroxypropyl methyl selulose aqueous solution viscosity nayo irashobora kuba nkumuhuza wingenzi kubitekerezo kubitekerezo biranga selile ya selile, uko hejuru yubukonje bwumuti wamazi, umubyimba wibikoresho bya sima ya epoxy nibyiza, nibyiza, inyuma yibintu bya plaque, ariko niba ibishishwa ari binini cyane, byangiza ibintu bya epoxy ciment. Kubijyanye na minisiteri imwe yo kwisuzumisha ifite amazi menshi, ubwiza bwa selile ya ether bizerekanwa ko biri hasi.
Cellulose ether yamazi yumuti numubiri wa pseudoplastique, twe mugice cyanyuma cyo kumenya igipimo cyogosha ni kinini, viscosity ni nto.
Kubwibyo, muri make ni: guhuriza hamwe kwa sima ya sima bizagabanywa nimbaraga zo hanze, zifasha mubwubatsi bwubwubatsi inyuma, ariko igisubizo cyamazi ya selulose ether mugihe habaye agaciro gake cyane, bizagaragaza ibiranga amazi atari Newtonian, kurundi ruhande, mugihe agaciro kokwiyongera kwinshi, igisubizo cyamazi kizaba kiranga pseudoplastique.
Kubika amazi muri hydroxypropyl methyl selulose nimwe mubintu byingenzi bya hydroxypropyl methyl selulose. Igipimo cyuka cyamazi yibintu bivangwa na minisiteri ivanze nibicuruzwa bya plasta bigira ingaruka kubushyuhe bwa gaze, ubushyuhe nigipimo cyumuvuduko. Kubwibyo, mubihe bitandukanye, wongeyeho hydroxypropyl methyl selulose ingano yingirakamaro yibicuruzwa byamazi bifite itandukaniro.
Muri rusange, uko ubukonje bwa hydroxypropyl methyl selulose bugenda burushaho kuba bwiza, niko ingaruka nziza yo gufata amazi izaba nziza, ariko ingaruka z’ubukonje bwo gufata amazi zizagabanuka nyuma yubukonje burenze 100.000 Mpa. s. Iyo ubwiza bwa HYDROXYpropyl methyl selulose burenga 100.000, igipimo cyo gufata amazi kirashobora kunozwa cyane mukongera ubwinshi bwa hydroxypropyl methyl selulose.
Mubikorwa birambuye byubwubatsi, ingaruka zo gufata amazi ya slurry zirashobora guhinduka muguhindura ingano ya hydroxypropyl methyl selulose. Hydroxypropyl methyl selulose yibicuruzwa birashobora gukemura neza ikibazo cyo gufata amazi munsi yubushyuhe bukabije. Mubihe byubushyuhe bukabije, cyane cyane ahantu hashyushye kandi harambiranye no kubaka chromatografiya kuruhande rwizuba, HYDROXYpropyl methyl selulose yujuje ubuziranenge irasabwa kugirango amazi agabanuke.
Ubwiza buhebuje bwa hydroxypropyl methyl selulose, bufite uburinganire bwiza, butili ya gatatu ya butyl na hydroxypropyl ogisijeni ikora hamwe na fibre molekulari yimiterere ihuriweho hamwe, irashobora guteza imbere itsinda rya methyl aldehyde hamwe na ogisijeni, kandi ubwiza bwamazi yububiko bwa digitale burashobora guhinduka, guhinduka amazi n'amazi yo gutatanya, hanyuma bikagenzura neza ikirere gikabije cyamazi.
Ubwiza bwa hydroxypropyl methyl selulose burashobora guhuza ubutaka bwubucuruzi nubucuruzi mubicuruzwa bivanze na minisiteri ivanze na pompe, hamwe nuduce twinshi twinshi cyst, itose, ikonje, kandi ikora urwego rwa firime, ubuhehere mugihe kirekire kirekuye buhoro buhoro buva mukibanza, hamwe nogutangira ibinyabuzima bivangwa ningaruka ziterwa na hydration reaction, hanyuma byemeza guhuza ibikoresho fatizo imbaraga zo gukomeretsa nimbaraga zikomeye. Mugihe cyubushyuhe bwo hejuru bwubushyuhe bwo mu cyi rero, kugirango bigere kumazi, bigomba kuba bihuye na resept yumubare runaka nubwiza bwibicuruzwa bya hydroxypropyl methyl selulose, bitabaye ibyo, bizerekana kurambirana byihuse kandi bitera hydratiya idahagije, kugabanya imbaraga zo kwikuramo, gucamo ibice, kwerekana imico nka metope ingoma yubusa no gushidikanya, nayo ihujwe nubushobozi bwubwubatsi bwabakozi. Mugihe ubushyuhe bugabanutse, ingano ya hydroxypropyl methyl selulose irashobora kugabanuka buhoro buhoro kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
Niba ether ya selile yongeyeho, chromatografi ya sima nshya ya sima izuma vuba, gukora beto ntishobora kuyoborwa muburyo busanzwe, bikavamo isima ya sima ntishobora gukomera no kubona neza. Muri icyo gihe, iyongerwaho rya selile ether ituma sima ya sima igira ihindagurika ryiza kandi igahinduka, kandi igahindura imbaraga zo guhuza imbaraga za sima ya sima.
1, hydroxypropyl methyl selulose ingano yubunini
Ingano yubunini bwa selile ether yangiza imbaraga zayo. Ether nziza ya selile nziza, niko umuvuduko wacyo wangirika mumazi kandi niko biranga amazi. Kubwibyo, ingano yubunini bwa selile ether igomba gushyirwa mubushakashatsi bwa kimwe mubiranga. Muri rusange, selile ya ether ingano ya 80 mesh ishingiye.
2, hydroxypropyl methyl selulose yumye nta gipimo cya rukuruzi
Manic yumye nta gipimo cya rukuruzi, bivuga ubushyuhe runaka bwa manic selulose ether yumye, gutakaza ubuziranenge bwimiti byagize ubwiza bwicyitegererezo cyambere cyijana cyibigize. Kubwiza runaka bwa selulose ether yumye idafite umuvuduko ukabije ni mwinshi, bizagabanya ibice bijyanye na selulose ether, byangiza ingaruka nyazo zo gukoresha ibigo byo hasi, ariko kandi bizamura igiciro cyubuguzi. Mubisanzwe selile yumye ya selile idafite igipimo cyingufu ntishobora kurenga 5.0%.
3, hydroxypropyl methyl selulose potassium thiocyanate ivu
Kubwiza runaka bwa selulose ether mubirimo ivu ni byinshi cyane, bizagabanya ether ya selulose mubice bijyanye, byangiza ingaruka zifatika zo gukoresha amasosiyete yo hasi, selulose ether potassium thiocyanate ivu ni byo byibanze byingenzi byerekana agaciro kayo.
4, hydroxypropyl methyl selulose viscosity
Hydroxypropyl methyl selulose igumana amazi ningaruka zo kubyimba nurufunguzo rwo kongeramo sima mortar selulose ether mubwiza bwayo no kuyishyiramo.
5, hydroxypropyl methyl selulose PH agaciro
Ubukonje bwibicuruzwa bya hydroxypropyl methyl selulose bigabanuka buhoro buhoro ku bushyuhe bwo hejuru cyangwa nyuma yo kubikwa igihe kirekire, cyane cyane kubicuruzwa byijimye cyane, bityo agaciro ka pH kagomba kuba gake. Mubisanzwe biteganijwe ko icyiciro cya PH agaciro ka selile ether igomba gukoreshwa nka 5-9.
6. Kwanduza hydroxypropyl methyl selulose
Ibyiza nibibi byo kwanduza hydroxypropyl methyl selulose irashobora kugira ingaruka itaziguye ingaruka zikoreshwa ryayo mubikoresho byubaka. Ibintu byibanze byangiza ihererekanyabubasha rya selile ether ni
1) ubwiza bw'ibikoresho fatizo; (2) ingaruka nyazo zo gukuraho; (3) Gutunganya ikoranabuhanga; (4) gutegura ibishishwa kama; (5) Ingaruka nyayo ya zhonghe.
Ukurikije ingaruka zifatika zifatika, kwanduza selile ya selile ntigomba kuba munsi ya 80%.
7, hydroxypropyl methyl selulose ikekwa ubushyuhe
Hydroxypropyl methyl selulosemubice bya sima nkurufunguzo rwo kongera ibifatika, ibishishwa hamwe nogukoresha amazi, bityo ubukonje nubushyuhe bwa gel nicyo kintu cyingenzi cyerekana agaciro ka hydroxypropyl methyl selulose. Ubushyuhe bukoreshwa muguhitamo ubwoko nibisobanuro bya selile ya selile, kandi urwego rwo gusimbuza ether selile.
8. Byongeye kandi, umunyu nibisigara nabyo bizangiza ubushyuhe bwa kole. Iyo ubushyuhe bwumuti wamazi buzamutse, fibre polymer ibura buhoro buhoro amazi, kandi ubwiza bwumuti wamazi buragabanuka. Iyo ingingo ifatika igeze, polymer yumye rwose kandi ifata umusaruro. Kubwibyo, ubushyuhe bwimikorere yabanyamuryango ba sima mubusanzwe buri munsi yubushyuhe bwambere bwa kole. Muri iki gipimo, ubushyuhe buri hasi, niko hejuru yubukonje, ningaruka zikomeye zifatika zo kwifata no kubika amazi.
