Hydroxypylm methylcellulose (hpmc) ndi polymer contraund yosiyanasiyana posintha cellulose zachilengedwe. Amagwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya ndi minda ina. Popanga zida zomangira, makamaka popanga matope, hpmc amatenga gawo lofunikira ndipo amatha kusintha zinthu zosiyanasiyana matope.
1. Kulimbikitsa madzi osungira matope
Kusunga kwamadzi kwa matope kumatanthauza kuthekera kwa matope kuti ukhale chinyezi chokwanira panthawi yomanga kapena kuwonongeka kwa madzi, komwe ndikofunikira kwambiri kwa matope. HPMC imatha kusintha bwino madzi osungira matope. Kupanga kwake molecular kuli ndi magulu ambiri a hydrophilic, omwe amatha kumwa madzi ndikupanga filimu ya hydration, potero kuchepetsa kuchuluka kwa madzi. Powonjezera hpmc ku matope, nthawi yomanga matope ikhoza kukulitsa ming'alu ndi kutsika kwamphamvu komwe kumachitika chifukwa cha kutaya madzi kwambiri.
2. Sinthani mwayi wazovuta ndi rheology ya matope
Kugwiritsa ntchito HPMC mu matope kungathandizenso kwambiri madzi ndi obisalamo. Ntchentche ya matope imatanthawuza madzi ndi kutumphukira kwake mothandizidwa ndi mphamvu zakunja, zomwe zimakhudza mosavuta pakumanga. HPMC, ngati polymer pofini, imatha kupanga mawonekedwe a colloidal, omwe amatha kupanga mayunifolomu ambiri komanso madzi ambiri nthawi yosakanikirana ndi kumanga, powonjezera kubizinesi kwake. Makamaka munjira monga zopaka ndi utoto, chivundi cha matope ndizofunikira kwambiri. Kuphatikiza kwa HPMC kumatha kupangitsa kuti matope azigwiritsa ntchito ndi chepetsa, kuchepetsa zovuta zomanga, ndikusintha ntchito.
3. Sinthani zotsatsa ndi anti-slip-malo a matope
Kutsatsa ndi chimodzi mwazomwe zimachitika kwambiri matope. Zimasankha chotsatsa pakati pa matope ndi gawo lapansi, ndipo limakhudza kukhazikika kwake ndi kukhazikika kwa nyumbayo. Mamolekyulu a HPMC ali ndi mphamvu yamphamvu komanso kapangidwe kake katatu, komwe kumapangitsa kutengera bwino pakati pa matope ndi gawo lapansi. Kafukufuku wawonetsa kuti matope ndi kuwonjezera kwa HPMC kumawonjezera cholumikizira pakati pa maziko, mwachangu ndikusintha mphamvu ya matope ndikuchepetsa mbale ndi maziko a matope ndi maziko.
HPMC ilinso ndi katundu wotsutsa-sliet, makamaka kutentha kwambiri komanso manyowa ambiri. HPMC imatha kupewa bwino matope kuchokera ku maluwa kapena kungoyambitsa, kuonetsetsa kuti matopewo amalumikizidwa kukhoma kapena malo ena omanga, makamaka popereka, ndi zina zambiri.
4. Sinthani kukana kwa matope
Munthawi yomangamanga, matope amayamba kugwedeza chifukwa cha zinthu zosiyanasiyana monga nyengo ndi maziko pansi. Kuphatikiza kwa HPMC kumatha kusintha kwambiri matope. Kapangidwe ka polymer kumatha kupanga mawonekedwe atatu okhala ndi matope, kukonza zotanuka komanso kusintha kwa matope, komanso kuthana ndi mavuto oyambitsidwa ndi kupanikizika kwakunja kapena kusintha kwa kutentha. Makamaka m'malo okhala ndi mizere yonyowa pafupipafupi komanso kusiyana kwa kutentha, hpmc imatha kuchepetsa kusokonekera ndikuyika matope ndikuwonjezera moyo wautumiki.
5. Sinthani mphamvu ndi kukhazikika kwa matope
Ngakhale HPMC yokha sitenga nawo mbali mwachindunji mu simenti ya simenti, imatha kusintha mphamvu ya matope posintha matope amkati. Pambuyo poti kuwonjezera HPMC, kufanana kwa matope kusinthidwa, kugawa kwa tinthu tating'onoting'ono kumakhala yunifolomu zambiri, ndipo zomwe pakati pa simenti ndi madzi ndizokwanira, zomwe zimathandizira kukonza zomaliza matope. Kuphatikiza apo, HPMC ilinso ndi luso linalake lotsutsa, lomwe limatha kusintha chibwibwi wamatope. Pogwiritsa ntchito nthawi yayitali, imatha kuchepetsedwa kuwonongeka ndi kuthamanga kwa matope.
6. Ntchito zina
Kuphatikiza pa zomwe zili pamwambazi pamwambapa, HPMC ili ndi ntchito zina mu matope, monga:
Sinthani ungwiro: hpmc imatha kuchepetsa kulowera kwa chinyezi ndi mpweya, kusintha chinyontho cha matope, kuletsa chinyezi kuti chisalowe mkati mwa nyumbayo, ndikuwonjezera kukana kwamadzi kwa nyumbayo.
Sinthani nthawi yowuma kwa matope: Posintha zomwe zili mu HPMC, nthawi ya matope ikhoza kulamulidwa bwino kuzolowera zomangamanga ndikuwonetsetsa kuti mukumanga kosavuta.
Sinthani kuteteza chilengedwe kwa matope: hpmc ndi zinthu zachilengedwe zabwinobwino. Kugwiritsa ntchito kumatha kuchepetsa kugwiritsa ntchito mankhwala owonjezera komanso kuchepetsa kuipitsa pachilengedwe.
Kugwiritsa ntchito hydroxypropyl methylcellulose mwa matope kungathe kukonza madzi, makamaka pokana, kusokoneza bongo, etc. M'tsogolomu, pofufuza za kafukufuku, kugwiritsa ntchito kwa HPMC ku matope kungayambike, kukonzanso kuchuluka kwa zinthu zomanga ndi ntchito yomanga.
