1. Incamake ya HPMC
Hydroxypropyl methylcellulose (HPMC muri make) ni ibikoresho bisanzwe bikoreshwa na polymer bisanzwe, bikoreshwa cyane mubwubatsi, gutwikira, ubuvuzi, ibiryo nibindi bice. HPMC iboneka muguhindura imiti ya selile karemano, ikagira amazi kandi ikabangikanya, kandi ntigishobora gukemuka mumashanyarazi. Bitewe n’amazi meza cyane yo gukomera, gufatana, kubyimba, guhagarikwa nibindi bintu, HPMC yakoreshejwe cyane mubikorwa byubwubatsi, cyane cyane mugukoresha ifu yuzuye.
2. Uruhare rwa HPMC mumashanyarazi
Ifu yuzuye ni ibikoresho byubaka bikoreshwa mugutunganya urukuta, kandi ibyingenzi byingenzi ni ibyuzuza hamwe. HPMC, nkibisanzwe byiyongera kandi bigumana amazi, birashobora kunoza neza imikorere yifu yifu, cyane cyane harimo ibi bikurikira:
Ingaruka yibyibushye: HPMC ikora igisubizo cya colloidal nyuma yo gushonga mumazi, ifite ingaruka zikomeye zo kubyimba, irashobora kunoza imiterere ya rheologiya yifu yifu, bigatuma igira ubukonje bukwiye, ikirinda kunanuka cyane mugihe uyisabye, kandi ikanoza imikorere.
Kunoza imikorere yubwubatsi: Ingaruka ya HPMC ntishobora gutuma ifu ya putty idashobora gusa kugabanuka cyangwa gutonyanga mugihe cyo gusaba, ariko kandi ikanongerera ifu yifu yifu, byoroshye kuyikoresha kurukuta, bityo bikazamura imikorere yubwubatsi.
Kunoza gufata neza amazi: HPMC irashobora kugumana neza amazi muri poro yuzuye kandi igabanya umuvuduko wamazi. Ibi birashobora kubuza ubuso bwifu yifu yumye vuba, kwemeza imikorere yayo mugihe cyubwubatsi, no kwirinda kumeneka no kumeneka.
Kunoza gukorakora no kugaragara neza: HPMC ntishobora kongera gusa ihindagurika ryifu yifu, ariko kandi irashobora kunoza ubuso bwayo, bigatuma igipande cyoroshye cyoroha, kikaba gifasha mubikorwa byo gusiga amarangi. Mugihe cyubwubatsi, HPMC irashobora gutanga ubworoherane no kugabanya kubyara inenge ninshi.
Kunoza ubwubatsi buhamye: Kwiyongera kwa HPMC birashobora kunoza imvura irwanya imvura yifu, birinda ko hajyaho uduce duto duto, kandi tukareba ko ubwiza n’imikorere yifu ya putty bitazahinduka cyane mugihe cyo kubika igihe kirekire.
Kunoza uburyo bwo guhangana n’amazi: Binyuze mu gufata amazi no kongera umubyimba wa HPMC, guhangana n’ifu ya putty birashobora kunozwa, gucika ku rukuta birashobora kwirindwa, kandi ubuzima bwa serivisi burashobora kongerwa.
3. Ubukonje bukwiye bwa HPMC
Ingaruka ya HPMC muri powder yifu ifitanye isano rya bugufi nubwiza bwayo. Guhitamo ibishishwa bigomba kugenwa hakurikijwe ibisabwa byihariye bya porojeri n'ibidukikije byubaka. Muri rusange, ubwiza bwa HPMC buva ku bihumbi magana kugeza ku bihumbi mirongo bya milipoise (mPa · s), muri byo ibimera bitandukanye bikwiranye nubwoko butandukanye bwifu yifu nibisabwa mubwubatsi.
Ubukonje buke HPMC (hafi 1000-3000 mPa · s): ibereye ifu yoroheje yoroheje cyangwa ifu fatizo, ikoreshwa cyane cyane mubihe bikenewe amazi menshi. Ubukonje buke HPMC burashobora gutanga imikorere myiza yo gutwikira, bigatuma ifu ya putty yoroshye gukora, ariko kubika amazi no kurwanya ibimeneka birakomeye.
Hagati ya viscosity HPMC (hafi 3000-8000 mPa ·) HPMC yiyi viscisi ntishobora gusa kuzuza ibisabwa mugihe cyo kubaka, ariko kandi irashobora gukumira neza ibibazo nko guturika no kugwa.
Ubukonje bwinshi HPMC (hafi 8000-20000 mPa · s): bubereye ibice byimbuto byifu cyangwa ibihe bisaba ingaruka zikomeye. Ubukonje bukabije HPMC irashobora gutanga uburyo bwiza bwo gutwikira neza kandi butajegajega, kandi burakwiriye muburyo bwo gutwikira busaba gukoraho gukomeye no koroshya, ariko twakagombye kumenya ko ubukonje bwinshi cyane bushobora gutuma ifu ya putty iba nziza cyane kandi bikagira ingaruka kubikorwa byubwubatsi.
Mubikorwa bifatika, ubwiza bwa HPMC bugomba gutoranywa ukurikije uburyo bwo gukoresha hamwe nuburyo bwo kubaka ifu ya putty. Kurugero, mugihe hejuru yurukuta rusa nkaho rukomeye cyangwa inyubako nyinshi zirakenewe, HPMC irashobora gutoranywa kugirango irusheho gukomera no guhangana nigitambara; mugihe mubihe bisaba gutemba kwinshi nubwubatsi bwihuse, hasi no hagati ya viscosity HPMC irashobora gutoranywa.
Hydroxypropyl methylcelluloseninyongera yingirakamaro yinyubako ishobora kunoza cyane imikorere yubwubatsi, kubika amazi, gufatira hamwe no kurwanya ifu yimbuto. Guhitamo neza neza HPMC ni ngombwa mugukoresha ifu yuzuye. Ibinyuranyo bitandukanye birashobora guhinduka ukurikije ubwoko bwifu ya putty, ibidukikije byubaka, nibisabwa gukora. Mubikorwa nyabyo nubwubatsi, kugenzura ubwiza bwa HPMC birashobora kugera kubikorwa byiza byubwubatsi nibikorwa byigihe kirekire. Kubwibyo, ukurikije ibyangombwa bitandukanye byubwubatsi, guhitamo neza no guhindura ubwiza bwa HPMC nintambwe yingenzi yo kwemeza imikorere nubuziranenge bwifu yifu.
