HydroxyPropyl methylcellse (HPMC) ni urujijo rwa polymer rwabonetse muguhindura imiti ya selile selile. Ifite amazi meza, adafite uburozi, odorlessness hamwe na biocompat. Kubwibyo, ikoreshwa cyane mu irangi, kubaka, imiti, ibiryo nibindi bice. Mu nganda zisize irangi, HPMC igira uruhare runini nkuwijimye, gishobora kunoza imikorere, gushikama no gutunganya ikoranabuhanga.
1. Uruhare rwa HPMC nka paing chicker
HPMC igira uruhare rukurikira nkuwijimye mu irangi:
(1) Ongera viscosiya
HPMC irashobora gukuramo amazi ikabyimba ahantu hashingiye kumazi ahanini binyuze mumirongo ya Polymer, ongera imikoranire iri hagati ya molekile, bityo yongera vinole yirangi. Ubwiyongere bwabasura butezimbere ibintu byimiterere no kuzamura imikorere ya pati irangi. By'umwihariko, HPMC irashobora gutuma imikorere yo gukaraba no gutera imbaraga zoroshye kandi irinde kunyeganyega cyane cyangwa gutonyanga.
(2) Kunoza ibintu byimiterere yibitekerezo
Gushyira mu bikorwa HPMC mubice birashobora kunoza uburyo bwabo bwimiterere, cyane cyane mubihe byinshi hamwe nigipimo cyinkombe nke, kandi birashobora gukomeza vicosi nziza no gutuza. Ibi ni ngombwa cyane mugutunganya amatara muburyo butandukanye, cyane cyane kubikorwa byubwubatsi mugihe cyoza ahantu hanini. Muguhindura uburemere bwibanze nuburemere bwa HPMC, amazi yo gupfukirana arashobora gutegekwa, kuburyo bidashoboka gutemba vuba mugihe cyo gukoresha, kandi ushobora gukomeza imiterere yubwubatsi.
(3) Kunoza ikwirakwizwa rya horizontal
Ingaruka zijimye za HPMC mubikota ntabwo ari ukuzuza virusi, ahubwo no kunoza urwego rwibiganiro. Gukwirakwiza gutambitse bivuga ubushobozi bwo gukwirakwiza bugabanijwe neza hejuru ya substrate nyuma yo koza nta ngaruka zidasanzwe cyangwa zitaringaniye. HPMC yongerera impagarara zo hejuru kandi igahitamo ibiranga ingurute, kugirango igikona kibe film imwe kandi yoroshye yo gutwikira hejuru.
(4) Kwiyongera igihe cyo gufungura
Nkumupfakazi, HPMC ifite kandi imikorere yo kurambura igihe cyo gukingira. Igihe cyeruye kivuga igihe coating ikomeza kugirira akamaro mugihe cyo gusaba. Kurera iki gihe gifasha gukumira ifuro yo kumisha vuba mugihe cyo koza, kiganisha ku kimenyetso kitaringaniye cyangwa brush ibimenyetso. HPMC itezimbere igipimo cyo guhumeka, yemerera igikoma gishingiye ku mazi gukomeza vino ikwiye igihe kirekire, ibuza inzira yo gutora.
(5) Kuzamura ituze ry'ikirere
Ingaruka zikabije za HPMC nazo zifasha kuzamura imihanda ihamye yo kwifuza, cyane cyane muri sisitemu ishingiye ku mazi, birashobora guhungabanya ibice bikomeye nka pigment n'abahuze, birinda kwikuramo. Muguhindura uburemere bwa moleculand nurwego rwo gusimbuza HPMC, gushikama kw'igitero birashobora kuba byiza kugirango bitagereranywa cyangwa bikaba byiza mugihe cyo kubika igihe kirekire.
2. Gusaba HPMC mumavuta ashingiye kumazi
Amazi ashingiye ku mazi yazamuwe cyane mu myaka yashize kubera kurengera ibidukikije, bidafite uburozi, ndetse n'umwanda muke. Gusaba HPMC mumavuta ashingiye kumazi ni ngombwa cyane. Ntabwo ari ugukora gusa nk'abakira, ahubwo binagira uruhare runini mu ngingo zikurikira:
(1) Kunoza amazi no gukorana
Amazi yibintu bishingiye kumazi akunze kwibasirwa nibirimo n'amazi. HPMC irashobora guhindura imiterere yamazi ashingiye ku mazi kugirango akomeze ubutwari bwo hejuru ku gipimo cy'iminsi mike, bityo akabona ko igikombe kigira uruhare runini mu gihe cyo guhinga. Byongeye kandi, HPMC irashobora kandi kunoza thixotropy yo kwifuza, ni ukuvuga, igikoma gifite ubukwe runaka muri leta ihamye, ariko irashobora kugabanya vuba vicosity mugihe cyo koroshya.
(2) Kunoza amazi yo kurwanya amazi
Molekile ya HPMC ikubiyemo amatsinda ya hydrophilic, ashobora kongeramo ubuhinzi bwo gutura mumazi kumazi. Mugihe cyumye cyo gupfuka, HPMC irashobora kugabanya neza ikibazo cyo guswera guterwa no guhumeka byihuse, utezimbere kurwanya amazi no gupfusha.
(3) Kuzamura umucyo na gloss yo gutwikira
Kubera ubwitonzi bwayo bworoshye, HPMC irashobora gufasha amabara ashingiye ku mazi akomeza gukorera mu mucyo na gloss. Mubyiciro byihariye byo gupima, nkibisanzwe no guhuza amakuru, gukoresha HPMC birashobora kugumana uburangare bwo gupfuka no kunoza urutare rwimpimbano ya nyuma.
3. Gusaba HPMC mumavuta ashingiye kuri peteroli
Mu mavuta ashingiye kuri peteroli, HPMC ikoreshwa cyane nkabakiranye na redulator na rheology. Nubwo HPMC ubwayo irimo gushonga amazi menshi, ingaruka nziza zijimye mumavuta ashingiye kuri peteroli iracyakoreshwa cyane. Mu rupapuro rushingiye kuri peteroli, HPMC irashobora guhindura neza viscolity ya irangi, itezimbere irangi kandi rifite imbaraga zo gukomera, kubuza imyanda, no kugabanya ikariso.
4. Ibyiza bya HPMC nka Thuckener
Ugereranije nababyimba gakondo, gusaba HPMC mu irangi bifite ibyiza bikurikira:
Kurengera ibidukikije: HPMC ni ukomoka kuri selile karemano kandi ntabwo birimo ibintu byangiza, ni byiza rero gukoresha mu gushushanya kandi ntabwo byera ibidukikije.
Amazi akomeye yonyine: HPMC ifite umubyibutozo mwiza kandi ituje mumashusho ashingiye kumazi, arashobora gutanga ingaruka nziza yijimye, kandi ntabwo izagira ingaruka kubindi bintu byirashe.
Imikorere myiza yubwubatsi: HPMC irashobora kunoza imikorere yubwubatsi yirangi, irinde gukata imburagihe no kugategabikorwa, kandi bikwiranye nibisabwa muburyo butandukanye.
Kunoza ihungabana ryububiko: HPMC irashobora gutuza imitungo yumubiri na shimi ya gusiga irangi kandi igabanya ibintu byimvura bishobora kubaho mugihe cyo kubika.
Nka irangi impimbano, HPMC ntishobora kongera ubukwe bwamashusho kandi itezimbere imiterere, ariko kandi izamura ituze, murwego rwo gushyira urwego rwirangi. Bikoreshwa cyane mumashusho ashingiye kumazi hamwe namashusho ashingiye kuri peteroli. Muguhindura imiterere yacyo hamwe nibitekerezo byayo, imikorere yicyubahiro irashobora guhinduka muburyo bwo guhangana nubwoko butandukanye bwibintu. Hamwe no gukenera kwiyongera kubanya bishingiye ku bidukikije no mu buryo buke-bwonyine, ibyifuzo bya HPMC bizagukwirakwiza kandi bizahinduka kimwe mu byongeyeho inyongeramusaruro.
