Putty nibikoresho byingenzi byubaka bikoreshwa mukuringaniza urukuta, kandi imikorere yabyo igira ingaruka itaziguye kumirangi hamwe nubwiza bwubwubatsi. Mugutegura putty, selile ya ether inyongeramusaruro igira uruhare runini.Hydroxypropyl Methylcellulose (HPMC), nkimwe mumyanya ikoreshwa cyane ya selile, irashobora kunoza neza ububobere, imikorere yubwubatsi hamwe nububiko bwa putty.
1. Ibintu shingiro bya Hydroxypropyl Methylcellulose
HPMC ni polymer idafite amazi-elegitoronike ifite umubyimba mwiza, kubika amazi, gutatanya, emulisitiya hamwe nibikorwa bya firime. Ubukonje bwacyo bugira ingaruka ku rwego rwo gusimburwa, urwego rwa polymerisation hamwe nuburyo bwo gukemura. Igisubizo cyamazi ya AnxinCel®HPMC yerekana ibiranga amazi ya pseudoplastique, ni ukuvuga, iyo igipimo cyogosha cyiyongereye, ubwiza bwumuti buragabanuka, nibyingenzi mukubaka kubaka putty.
2. Ingaruka za HPMC kuri viscosity
2.1 Ingaruka
HPMC ikora igisubizo kinini cyijimye nyuma yo gushonga mumazi. Ingaruka yabyimbye igaragarira cyane cyane mubice bikurikira:
Kunoza thixotropy ya putty: HPMC irashobora kugumya gushira hejuru cyane mugihe ihagaze kugirango yirinde kugabanuka, kandi igabanye ubukonje mugihe cyo gusiba no kunoza imikorere yubwubatsi.
Gutezimbere imikorere ya putty: Umubare ukwiye wa HPMC urashobora kunoza amavuta ya putty, bigatuma gusiba byoroha no kugabanya kurwanya ubwubatsi.
Ingaruka ku mbaraga zanyuma za putty: Ingaruka yibyibushye ya HPMC ituma ibintu byuzuza hamwe na simaitima muri putty bitatanye, birinda amacakubiri no kunoza imikorere ikomera nyuma yo kubaka.
2.2 Ingaruka kubikorwa byo kuyobora
HPMC ifite uburyo bwiza bwo gufata amazi, bushobora kugabanya guhumuka vuba kwamazi murwego rwa putty, bityo bikongerera igihe cyo kuvomera amazi ashingiye kuri sima no kunoza imbaraga no kurwanya ibishishwa. Nyamara, ubukonje bukabije bwa HPMC buzagira ingaruka ku ihindagurika ry’ikirere no kwihuta kwumuvuduko, bigatuma ubwubatsi bugabanuka. Kubwibyo, ingano ya HPMC ikeneye kwemeza imikorere mugihe wirinze ingaruka mbi mugihe gikomeye.
2.3 Isano iri hagati yuburemere bwa molekuline ya HPMC nubwiza bwa putty
Uburemere buremereye bwa HPMC, niko ubwiza bwumuti wabwo wamazi. Muri putty, gukoresha HPMC ifite ubukana bwinshi (nkubwoko bufite ubukonje burenga mPa · s 100.000) burashobora kunoza cyane gufata neza amazi hamwe no kurwanya kugabanuka kwa putty, ariko birashobora no gutuma igabanuka ryakazi. Kubwibyo, mubisabwa bitandukanye byubwubatsi, HPMC ifite ubukonje bukwiye igomba guhitamo kuringaniza gufata amazi, gukora nibikorwa byanyuma.
2.4 Ingaruka za dosiye ya HPMC kuri viscosity
Ingano ya AnxinCel®HPMC yongeyeho igira ingaruka zikomeye ku bwiza bwa putty, kandi dosiye isanzwe iri hagati ya 0.1% na 0.5%. Iyo urugero rwa HPMC ruri hasi, ingaruka zo kubyimba kuri putty iba mike, kandi ntishobora kunoza neza imikorere no gufata amazi. Iyo dosiye ari ndende cyane, ubwiza bwa putty ni bunini cyane, ubwubatsi bwubaka bwiyongera, kandi bishobora kugira ingaruka kumisha yumuvuduko. Niyo mpamvu, birakenewe guhitamo umubare ukwiye wa HPMC ukurikije formula ya putty nibidukikije byubaka.
Hydroxypropyl methylcellulose igira uruhare mukubyimba, gufata amazi no kunoza imikorere muri putty. Uburemere bwa molekile, urwego rwo gusimbuza hamwe ninyongera yaHPMCBizagira ingaruka kuri viscosity ya putty. Umubare ukwiye wa HPMC urashobora kunoza imikorere no kurwanya amazi ya putty, mugihe kwiyongera birenze bishobora kongera ingorane zo kubaka. Kubwibyo, mubikorwa nyabyo byo gushira, ibiranga ubwiza bwibisabwa hamwe nubwubatsi bwa HPMC bigomba gusuzumwa byimazeyo, kandi formula igomba guhindurwa muburyo bwiza kugirango ibone imikorere myiza yubwubatsi nubwiza bwa nyuma.
