Itandukaniro riri hagati ya hydroxypropyl starch ether (HPS) na selile ya ether

Hydroxypropyl ibinyamisogwe ether (HPS)naselile etherni ibintu bibiri bisanzwe byubaka imiti, bikoreshwa cyane mubikoresho byubwubatsi, nka minisiteri, ifu ya putty, coatings, nibindi. Nubwo bifite aho bihuriye mumitungo imwe n'imwe, hariho itandukaniro rigaragara mubintu byinshi nkibikoresho fatizo, ibikoresho bya shimi, imiterere yumubiri , Ingaruka zo gusaba, hamwe nigiciro.

1. Inkomoko yibikoresho nuburyo bwimiti
Hydroxypropyl ibinyamisogwe ether (HPS)
HPS ishingiye kuri krahisi isanzwe kandi iboneka binyuze muri etherification modification reaction. Ibikoresho byingenzi byingenzi ni ibigori, ingano, ibirayi nibindi bimera bisanzwe. Molekile ya krahisi igizwe nibice bya glucose bihujwe na α-1,4-glycosidic hamwe nubunini buke bwa α-1,6-glycosidic. Nyuma ya hydroxypropylation, itsinda rya hydrophilique hydroxypropyl ryinjijwe mumiterere ya molekile ya HPS, riguha ibikorwa bimwe byo kubyimba, kubika amazi no guhindura imikorere.

selile ether
Ether ya selile ikomoka kuri selile karemano, nka pamba cyangwa ibiti. Cellulose igizwe na glucose ibice bihujwe na β-1,4-glycosidic. Ethers isanzwe ya selile irimo hydroxypropyl methylcellulose (HPMC), methylcellulose (MC), hydroxyethyl selulose (HEC), nibindi.

2. Imiterere yumubiri
Ibiranga imikorere ya HPS
Kubyimba: HPS igira ingaruka nziza yo kubyimba, ariko ugereranije na selile ya selile, ubushobozi bwayo bwo kubyimba bugabanuka.
Kubika amazi: HPS ifite amazi meza kandi ikwiranye nibikoresho byubaka byo hagati cyangwa hagati.
Imikorere: HPS irashobora kunoza imikorere ya minisiteri no kugabanya kugabanuka mugihe cyo kubaka.
Kurwanya ubushyuhe: HPS yunvikana cyane nubushyuhe kandi yibasiwe cyane nubushyuhe bwibidukikije.

Ibiranga imikorere ya selile
Umubyimba: Cellulose ether igira ingaruka zikomeye kandi irashobora kongera cyane ububobere bwa minisiteri cyangwa putty.
Kubika amazi: Cellulose ether ifite uburyo bwiza bwo kubika amazi, cyane cyane mubushyuhe bwo hejuru, bushobora kongera igihe cyo gufungura minisiteri kandi bikarinda gutakaza amazi menshi.
Imikorere: Cellulose ether ninziza mugutezimbere imikorere kandi irashobora kugabanya neza ibibazo nko guturika no kumena ifu.
Kurwanya ubushyuhe: Ether ya selile ifite imbaraga zo guhuza n'imihindagurikire yubushyuhe kandi imikorere ihamye.

3. Ingaruka zo gusaba
Ingaruka yo gusaba yaHPS
Muri minisiteri yumye, HPS igira uruhare runini mu kunoza imikorere, kunoza imikoreshereze y’amazi, no kugabanya gusenya no gutandukanya. Nubukungu kandi burakwiriye gukoreshwa mubintu bisabwa kugenzura ibiciro, nkibisanzwe bisanzwe byurukuta rwimbere, ifu iringaniza hasi, nibindi.

Ingaruka yo gukoresha selile
Etherzikoreshwa cyane muri minisiteri ikora cyane, yometse kuri tile, ibikoresho bishingiye kuri gypsumu hamwe na sisitemu yo gukingira urukuta. Ubwiza bwayo buhebuje hamwe no kubika amazi birashobora kunoza cyane imbaraga zo guhuza hamwe no kurwanya kunyerera yibikoresho, kandi birakwiriye cyane cyane kumishinga ifite ibisabwa byinshi mubikorwa byubwubatsi nubwiza bwibicuruzwa byarangiye.

4. Ibiciro no kurengera ibidukikije
igiciro:
HPS ifite igiciro gito kandi irakwiriye gukoreshwa mumasoko yita kubiciro. Ether ya selile irahenze cyane, ariko ifite imikorere myiza kandi ihendutse mugusaba imishinga yubwubatsi.

Kurengera ibidukikije:
Byombi bikomoka kubikoresho bisanzwe kandi bifite ibidukikije byiza. Nyamara, kubera ko imiti mike ikoreshwa muburyo bwo gukora HPS, umutwaro w’ibidukikije urashobora kuba muke.

5. Ishingiro ryo gutoranya
Ibisabwa mu mikorere: Niba ufite ibisabwa byinshi kubyimbye no kubika amazi, ugomba guhitamo selile; kubikoresho byoroha ariko bisaba kunonosorwa mubikorwa, urashobora gutekereza gukoresha HPS.
Ikoreshwa ryikoreshwa: Kubaka ubushyuhe bwo hejuru, kubaka urukuta rwo hanze, gufatira tile hamwe nibindi bintu bisaba inkunga yimikorere ihanitse birakwiriye kuri selile ya selile; kurukuta rusanzwe rwimbere rushyizwemo cyangwa minisiteri yibanze, HPS irashobora gutanga ibisubizo byubukungu kandi bifatika.

Hydroxypropyl ibinyamisogwe ethernaselile ether buriwese afite ibyiza bye kandi afite uruhare rutandukanye mubikoresho byo kubaka. Guhitamo bigomba gusuzumwa neza hashingiwe kubisabwa mu mikorere, kugenzura ibiciro, ibidukikije byubaka nibindi bintu byumushinga runaka kugirango ugere ku ngaruka nziza zo gukoresha.
