Hydroxypropyl methylcellulose (hpmc)ndi polymer-sungunuka wamadzi wochokera ku cellulose, bipolymer yachilengedwe.Dyera®HPMC imagwiritsidwa ntchito kwambiri m'makampani omanga, makamaka mu matope ndi mapangidwe apapa. Udindo wake womwe umagwiritsidwa ntchito ndikuwongolera malo osungira matope, omwe ndi ofunikira kuti akwaniritse njira zoyenera kusakanikirana ndi njira zamagwiritsidwe.
Udindo wamadzi kusungiramo matope
Kusungidwa kwamadzi mu matope kumatanthauza kuthekera kwa kusakaniza kwa madzi atayika pamtunda, kumangolola kuti zikhale zolimba komanso zopanda pake. Kusungidwa kwa madzi kumatsimikizira kuti matope amatha kukhala ogwirizana kwambiri ndi gawo lapansi komanso kumalepheretsa mavuto monga kusokonekera, shsing, kapena modikira bwino. Kusungidwa kwamadzi kosakwanira kumatha kukhala kosakwanira, kumapangitsa kuti olumikizira matope, amachepetsa mphamvu, kapena kuumitsa msanga.
Kusungidwa kwamadzi ndikofunikira kwambiri kwa matope owuma, omwe ndi zophatikizira za simenti, mchenga, ndi zowonjezera. Akasakanizidwa ndi madzi pamalo ogwiritsira ntchito, mavule mafoni azikhala ndi chinyezi chokwanira chokwanira kuchiza, potero amatha kukhala ndi mphamvu zambiri komanso kukhazikika. Pankhaniyi, HPMC imachita mbali yofunika kwambiri pakuwongolera madzi ndikuthandizira kugwiritsidwa ntchito ndi matope.
Momwe HPMC imathandizira kuti mavule a mavule
Madzi-solsubility ndi gel opanga: HPMC ndi polymer yosungunuka yamadzi yomwe imapanga kapangidwe kake ngati gel osakanikirana ndi madzi. Kupanga kwa gel kumeneku kumatha kuyika mamolekyulu amadzi ndikuchepetsa kufalikira kwa madzi, potero kuwonjeza kuchuluka kwa madzi osungika. Gel ayopheretsa matope mwachangu, kukhala ndi chinyezi choyenera panthawi yomwe mwachiritsa.
Kuwongolera ma viru: Makulidwe a kusakaniza matope amakhudzidwa ndi kukhalapo kwa HPMC, yomwe imathandizira kukhazikika. Mwakuwonjezereka ma virus, hpmc amatsimikizira kuti madzi amagawidwanso nthawi yonse yosakaniza ndikuthandizira kupewa tsankho la madzi ndi tinthu tokhazikika. Maonekedwe oyendetsedwa sangowongolera kusungidwa kwa madzi komanso kumathandiziranso kugwira ntchito, kupangitsa kuti ikhale yosavuta kuigwiritsa ntchito ndikufalikira.
Kupewa Kuthana Kwatsopano: Mukamagwiritsa ntchito matope, kusangalatsidwa msanga kumatha kuchitika chifukwa cha kuchepa kwa madzi mwachangu. HPMC imathandizira kuchepetsa njirayi pochita ngati wololera madzi. Izi zikuwonetsetsa kuti matonthowo amakhala onyowa nthawi yayitali, kulola kutsatira bwino malo ndikupewa ming'alu yomwe ingapangire chifukwa cha mankhwala osokoneza bongo.
Chotsanda bwino: Monga HPMC imathandizira kusungidwa kwamadzi, kumatsimikizira kuti pali chinyezi chosasinthasintha kwa simenti tating'onoting'ono tomwe timakhala ndi hydrate moyenera komanso ophatikizika. Izi hydrateted imapangitsa kuti pakhale kulumikizana mwamphamvu pakati pa matope ndi gawo lapansi, kukonza zomatira komanso ntchito zonse. Ndizopindulitsa kwambiri mukamagwira ntchito ndi zida zapamwamba, monga njerwa kapena konkriti, zomwe zimakonda kuyamwa chinyezi mwachangu.
Ubwino wa HPMC ku matope
| Pindula | Kaonekeswe |
| Kusunga kwamadzi | HPMC imapanga gel yomwe imathandizira kukonza madzi mu matope, kupewetsa kuyanika ndikuwonetsetsa kuthirako. |
| Onjezerani kugwirira ntchito | Kuwonjezeka kwa ma visction kumathandiza kusakaniza kwa kusakanikirana kwa kusakanikirana kwa kusakanikirana kwa kusakanikirana kwa kusakanikirana kwa kusakanikirana kwa kusakanikirana kwa, kufalikira, ndi mawonekedwe. |
| Kuchepetsa shrinkage ndi kusokonekera | Poletsa madzi oyambilira, hpmc amathandizira kuchepetsa kupezeka kwa ming'alu yomwe imatha kukula chifukwa cha shrinkage. |
| Kupewera Kusankha | HPMC imathandizira kukhazikika pakusakaniza ndikuonetsetsa kufalitsa kwamadzi ndi okalamba, kupewa kupatukana. |
| Zomatira zosintha komanso zomangira | Kusungidwa kwa chinyezi komwe kumaperekedwa ndi HPMC kumalimbikitsa kwambiri mgwirizano pakati pa matope ndi gawo lapansi, zomwe zimathandizira kulimba komanso mphamvu. |
| Kuchuluka kotseguka | Matope omwe ali ndi HPMC amakhalabe okhwima kwa nthawi yayitali, amalola nthawi yambiri yosintha ndikuwongolera panthawi yomwe ntchito. |
| Kulimbikitsa magwiridwe antchito owuma | M'madera omwe ali ndi mitengo yokwera kwambiri, kuthekera kwa HPMC kuyika madzi kumatsimikizira kuti matonthowo amakhala okhwima ndipo sauma msanga. |
Ntchito za HPMC kutope
HPMC imagwiritsidwa ntchito kawirikawiri m'mitundu yosiyanasiyana yamati, kuphatikiza:
Zilonda za Tile: Matanda matope, hpmc amasintha kusungidwa kwamadzi, kuonetsetsa hydration koyenera kwa tinthu tating'onoting'ono ndi kukulimbikitsani.
Matope ogona owonda: Manyanga omagona, omwe amagwiritsidwa ntchito poika ma tale, apindule ndi hpmc popeza amathandizira kukhalabe ndi chinyezi choyenera kuti mukhale ndi chinyezi choyenera komanso chokwanira.
Konzani matope: Pokonza ming'alu ndi malo owonongeka, hpmc imathandizira kusungidwa kwamadzi kwa matope, kuloledwa kulima ndi nyumba zomwe zilipo ndikuletsa kuyanika.
Pulasitala ndi stucco: Pakufunsira mapulogalamu, hpmc amaonetsetsa kuti kusakaniza matonthoyo amasunga madzi okwanira komanso kuchiritsa bwino, makamaka m'malo otentha kapena owuma.
Owuma matope: Zogulitsa za matope osakanikirana, kuphatikizapo zomangajambula komanso zomanga zambiri, zimapindulitsa ndi madzi a HPMC, zomwe zimasintha kusungidwa ndi magwiridwe antchito.
Zinthu zomwe zikukhudza kufunika kwa HPMC ku matope
Ngakhale HPMC imapereka zabwino zambiri, kugwira ntchito kwake pokonza madzi kusungitsa kungatengedwe ndi zinthu zingapo:
Kukhazikika kwa hpmc: Kuchuluka kwaDyera®HPMC yogwiritsidwa ntchito mu savar kusakaniza kwa matope mwachindunji zimakhudzanso malo ake osasunga madzi. HPMC yaying'ono kwambiri singapatse kusungidwa kwamadzi, pomwe kuchuluka kwambiri kumatha kukhumudwitsa matope a matope komanso kugwirira ntchito.
Lembani ndi kalasi ya HPMC: Mitundu Yosiyanasiyana ndi Maphunziro a HPMC alipo, iliyonse yokhala ndi madigiri osiyanasiyana a mafakisoni, kusungunuka, ndi luso la gel. Kusankha mtundu woyenera wa hpmc kuti mugwiritse ntchito mwapadera ndikofunikira kuti mukwaniritse madzi osungidwa ndi matope.
Zinthu Zachilengedwe: Kusakaniza matope ndi HPMC kumatha kukhala mosiyanasiyana mu chilengedwe chonse. Kutentha kwambiri kapena chinyezi chochepa kwambiri kumatha kuwonjezera mitengo ya Evapooment, yomwe mwina imachepetsa mphamvu ya HPMC mumadzi posungira. M'mikhalidwe yotere, njira zowonjezereka zingafunikire kuonetsetsa kuti mumayenera kugwiritsa ntchito mankhwala oyenera.
Kugwirizana ndi zina zowonjezera: Kusakaniza matope nthawi zambiri kumakhala ndi zowonjezera zosiyanasiyana, kuphatikizapo ma pulasitiki, ogulitsa, kapena othamanga. Kuyanjana pakati pa HPMC ndi zosakaniza zina kuyenera kuwonedwa kuti zitsimikizire kuti amagwira ntchito mobwerezabwereza kuti apititse matope.
Hpmcndizowonjezera mphamvu kwambiri pamatope, makamaka chifukwa cha kuthekera kwake kukonza madzi. Popanga mawonekedwe a gel osamalira mamolekyulu amadzi, hpmc amathandizira kuyanika kwa nthawi yokhazikika, kumawonjezera kugwiritsidwa ntchito kwa kusakaniza, ndikuwonetsetsa kuti ndizabwino kwambiri tinthu tating'onoting'ono. Izi zimathandizira kuti zisinthe mokweza, kuchepa, komanso kukulitsa matope. Kugwiritsa ntchito Dyera®HPMC imapindulitsa makamaka m'malo okhala ndi mitengo yokwera kapena yogwiritsira ntchito pofuna kutero. Kumvetsetsa zinthu zomwe zimapangitsa magwiridwe antchito a HPMC ndikusankha zolondola ndi mtundu wa nthawi iliyonse kugwiritsa ntchito kumatha kukonza matope.
