1. Kusunga kwamadzi
Kusunga kwamadzi kokha matope ndi kofunikira.Hydroxypropyl methylcellulose (hpmc)ili ndi mphamvu yolimba yamadzi. Pambuyo powonjezera matope opaka matope, imatha kupanga ma netiweki osungira matope mkati mwa matope kuti madzi asamale kapena kuti asungunuke mwachangu. Mwachitsanzo, mukakhala pamiyala ina yowuma, ngati palibe njira yabwino yosungira madzi, madzi m'tavalayo adzayamwa msanga ndi maziko, zomwe zimapangitsa kuti simenti yosakwanira. Kukhalapo kwa HPMC kuli ngati "micro-reservoir". Malinga ndi maphunziro oyenera, kuyika matope ndi kuchuluka kwa hpmc yoyenera kusunga chinyezi kwa maola angapo kapena ngakhale masiku angapo osakhala ndi HPMC pansi pa malo omwewo. Izi zimapatsa nthawi yokwanira kuti ichitike hydration machitidwe, mwakuwonjezera mphamvu ndi kukhazikika kwa matope owoneka bwino.
Kusungidwa koyenera kumathandizanso kukonza matope opangira matope. Ngati matoniwo ataya madzi mwachangu, imakhala youma komanso yolimba kuti igwiritsidwe ntchito matope, kuti omanga omanga amakhala ndi nthawi yokwanira kuti akhale ndi matope okwanira.
2. Modelion
HPMC imatha kukulitsa kutsatira pakati pa matope a plaster ndi maziko. Ili ndi mgwirizano wabwino, womwe umatha kupangitsa matonthoyo kutsatira pansi malinga ndi makoma ndi simenti. Pamapulogalamu othandiza, izi zimathandiza kupewa kusala ndi kugwa kwa matope a pulasitiki. Pamene hpmc mamolekyulu amalumikizana ndi pansi ndikuti tinthu tating'onoting'ono tating'ono, network yolumikizira imapangidwa. Mwachitsanzo, mukamayala pamalo ena osalala, matope a pulasitiki omwe ali ndi HPMC omwe amawonjezeredwa kwambiri pamtunda, kukonza kukhazikika kwa kapangidwe kake, ndikuwonetsetsa kuti polojekiti yopatulikitsa.
Kwa zigawo za zinthu zosiyanasiyana, hpmc zimatha kukhala ndi gawo labwino lolimbitsa mtima. Kaya ndi zomanga, nkhuni kapena chitsulo, bola ngati zili pamalo pomwe pulasitiki zimafunikira, HPMC imatha kukonza momwe mukugwirira ntchito.

Sinthani kutopa. Kuphatikiza kwa HPMC kumapangitsa matope owoneka bwino, ndipo matonthowo amakhala odetsedwa komanso osalala, omwe ndi abwino pantchito yomanga. Ogwira ntchito zomanga amatha kufalitsa ndikupukusa matope mosavuta ndikamazigwiritsa ntchito zovuta komanso kugwira ntchito yomanga. Izi ndizofunikira kwambiri pamapulojekiti akulu opangira zojambula zazikulu, zomwe zitha kupititsa patsogolo luso la kumanga ndi mtundu.
Odana ndi osaka. Mukakhala pamalo ofukula kapena okonda, kuvala matope amayamba kusaka, ndiye kuti, matope amayenda pansi mothandizidwa ndi mphamvu yokoka. HPMC imatha kuwonjezera mafayilo ndi kusasinthika kwa matope ndikupewa kusamba. Zimathandizira matope kukhalabe m'malo osakhazikika kapena kuyenda ndi kusokonekera, ndikuonetsetsa kuti ndi kukongola. Mwachitsanzo, kupanga matope opaka pakhomo, pomwepo ndi HPMC yowonjezeredwa imatha kusintha zofunikira zomanga kukhosi, ndipo zomanga sizingakhudzidwe.
4. Mphamvu ndi Kukhazikika
KuyambiraHpmcamawonetsetsa kamenti wathunthu, mphamvu ya matope yopatulika yakhala bwino. Kukwera kwambiri kwa simenti hydration, zinthu zamatsenga zimapangidwa. Zogulitsa izi hydrate ndizolumikizana kuti zipange kapangidwe kake, mwakuwonjezerani mphamvu zosonyeza mphamvu za matope, monga kuponderezana komanso kuthamangitsidwa ndi kuthekera kwathupi. Pakapita nthawi, izi zimathandizanso kukonza chibwibwi cha matope oyala.
Potengera kulimba, hpmc imathanso kusewera gawo linanso kukana. Zimachepetsa kupezeka kwa ming'alu yowuma chifukwa chongoyambitsidwa ndi chinyezi chosasinthika posungabe kugawa chinyontho. Nthawi yomweyo, madzi osungira HPMC amathandizira kuti athetse kukokoloka kwa zinthu zachilengedwe pakapita nthawi yayitali, monga kupewa kuwonongeka kwa chinyezi etc.
