Matope onyowa ndi simenti, ophatikizika, kuphatikizika, madzi ndi zigawo zingapo zotsimikiza molingana ndi magwiridwe antchito. Malinga ndi gawo linalake, atayezedwa ndi kusakaniza mu malo osakanikirana, amatengedwa kupita kumalo osakanizika, ndikuyika muyezo wapadera womwe umasungidwa mu chidebecho ndikugwiritsa ntchito nthawi yodziwika.
Hydroxypylpyl imagwiritsidwa ntchito ngati wothandizira madzi ndikubwezeretsa matope a simenti kuti apangitse matope. Kugwiritsidwa ntchito ngati binder mu pulasitala yopaka, imasintha ndikupitilira nthawi yogwira ntchito. Kusunga kwamadzi kwa Hydroxypypyl HPMYCEAS HPMC kumalepheretsa kusala chifukwa cha kuwonongeka chifukwa cha kuwuma mwachangu pambuyo pogwiritsa ntchito. Kusunga kwamadzi ndikofunikira kofunikira kwa hydroxypylropyl hpmc, ndipo ndi ntchito yomwe anthu ambiri osakanikirana amasakanikirana. Zinthu zomwe zikukhudza madzi kubwezeretsa madzi osakanizidwa ndi HPMC yowonjezeredwa, mafayilo a ma tinthu, komanso kutentha kwa malo ogwiritsira ntchito.
Udindo wofunikira wa hydroxypropyl a methylcellulose hpmc mu matope onyowa makamaka, ina ndiyabwino pa matope osakaniza, ndipo chachitatu ndi kulumikizana ndi simenti. Madzi osunga ma cellulose ethel ether amatengera madzi ophatikizika, kapangidwe ka matope, makulidwe a matope, kufunidwa kwamadzi kwa matope. Zowonjezera zowonjezera za hydroxypropyl methylcelulose, kukonzanso kwamadzi.
Zinthu zomwe zikukhudza madzi osungira madzi osakaniza zimaphatikizapo mawonedwe a celluuse, kuwonjezera, tinthu tating'onoting'ono komanso kugwiritsa ntchito kutentha. Kuunika kwa cellulose ether ether, yabwinobwino. Makulidwe ndi gawo lofunikira la hpmc. Pazinthu zomwezo, chidwi cha mafayilo omwe chimayesedwa ndi njira zosiyanasiyana ndizosiyana kwambiri, ndipo ena amakhala ndi kusiyana pang'ono. Chifukwa chake, poyerekeza mawonekedwe, ziyenera kuchitika pakati pa njira zomwezi, kuphatikizapo kutentha, rotor, etc.
Nthawi zambiri, mafakiti apamwamba, abwinobwino amadzisungira madzi. Komabe, mafayilo apamwamba komanso okwera kwambiri kwa kulemera kwa HPMC, kutsika kolingana kofananira mu kusungunuka kwake kumabweretsa zovuta pa nyonga ndi matope omanga. Maonekedwe ake, zoonekeratu kuti zimakula kwambiri patavala matope, koma siyofanana mwachindunji. Matope owoneka bwino, ndiye kuti, pomanga, amawonetsedwa ngati kumamatira ku starpiper ndi kutsatira kwakukulu kwa gawo lapansi. Koma sizothandiza kukulitsa mphamvu ya matonthozo onyowa. Pakumanga, magwiridwe antchito a Anti-Anti-sag sizachidziwikire. M'malo mwake, ena osinthidwa methylcellulose kapena mawonekedwe apakati komanso otsika ali ndi mapangidwe abwino kwambiri pokonzanso mphamvu ya matope onyowa.
Kuchuluka kwa cellulose ether hpmc yowonjezeredwa mu matope osakanikirana, magwiridwe antchito abwino a madzi, komanso mawonekedwe owoneka bwino, abwinowo omwe amasunga madzi. Ubwino ndi mndandanda wofunikira wa magwiritsidwe antchito a hydroxypropyl methylcellulose.
Chisangalalo cha hydroxypropyl methylcellulose umakhudzanso kusungidwa kwamadzi. Nthawi zambiri, hydroxypropyll methylcellulose ndi mawu omwewo koma njira zosiyanasiyana, yabwino kwambiri yomwe madzi osamala amakhala bwino.
M'matope onyowa, osakanizika a ether hpmc ndi otsika kwambiri, koma amatha kusintha matope opangira matope osakanizika, ndipo ndi chowonjezera cha chonyowa chomwe chimakhudza matope omanga. Kusankha koyenera kwa hydroxypypyl methylcellulose ali ndi mphamvu kwambiri pakusintha kwa matope osakanizika.
