HPMC (Hydroxypropyl Methylcellulose)ndi polima osungunuka m'madzi osinthidwa kuchokera ku cellulose wachilengedwe. Amagwiritsidwa ntchito kwambiri m'magawo ambiri monga zomangamanga, zokutira, zamankhwala, ndi zakudya. M'makampani omanga, HPMC, monga chowonjezera chofunikira chamatope, imatha kusintha kwambiri magwiridwe antchito amatope ndikuwonjezera kuthekera kwake, kusunga madzi, kugwira ntchito, kumamatira, ndi zina zambiri.
1. Ntchito zoyambira ndi ntchito za HPMC
HPMC ili ndi zotsatirazi:
Kukhuthala:AnxinCel®HPMCakhoza kwambiri kuonjezera mamasukidwe akayendedwe a matope, kupanga matope yunifolomu ndi khola, ndi yosavuta kugwiritsa ntchito pomanga.
Kusungirako madzi: HPMC imatha kuchepetsa kutuluka kwa madzi mumatope, kuchedwetsa kuuma kwa matope, ndikuwonetsetsa kuti matopewo sauma msanga panthawi yomanga, potero kupewa kuchitika kwa ming'alu.
Rheology: Posintha mtundu ndi mlingo wa HPMC, madzi amadzimadzi amatha kusintha, kupangitsa kuti ikhale yosavuta komanso yosavuta kupanga panthawi yogwiritsira ntchito.
Kumamatira: HPMC ili ndi gawo lina la zomatira ndipo imatha kukulitsa mphamvu yolumikizirana pakati pa matope ndi zinthu zoyambira, zomwe ndizofunikira kwambiri pakugwiritsa ntchito monga matope owuma ndi matope okongoletsa akunja.
2. Kugwiritsa ntchito HPMC mumatope osiyanasiyana
2.1 Kugwiritsa ntchito pulasitala matope
Plastering mortar ndi mtundu wa matope omwe amagwiritsidwa ntchito pomanga. Nthawi zambiri amagwiritsidwa ntchito popenta ndi kukongoletsa makoma, kudenga, ndi zina. Ntchito zazikulu za HPMC popaka matope ndi awa:
Kupititsa patsogolo magwiridwe antchito: HPMC imatha kuwongolera kuchuluka kwa pulasitala matope, kupangitsa kuti ikhale yofananira komanso yosalala panthawi yomanga, kuti zikhale zosavuta kwa ogwira ntchito yomanga kuti azigwira ntchito ndikuchepetsa kulimbikira kwa ogwira ntchito.
Kusungidwa kwamadzi kowonjezera: Chifukwa cha kusungidwa kwa madzi kwa HPMC, matope opaka pulasitala amatha kusunga chinyezi chokwanira kuti matope asaume mwachangu, zomwe zimayambitsa mavuto monga ming'alu ndi kukhetsa panthawi yomanga.
Limbikitsani kumamatira: HPMC imatha kukonza zomatira pakati pa matope ndi gawo lapansi la khoma, kuteteza matope kuti asagwe kapena kusweka. Makamaka m'mapulojekiti opaka khoma akunja, amatha kupewa kuwonongeka kwamapangidwe chifukwa cha zinthu zakunja monga kusintha kwa kutentha.
2.2 Kugwiritsa ntchito mumatope otsekereza khoma
Kunja kwa khoma kutchinjiriza matope ndi mtundu wa matope ophatikizika, omwe nthawi zambiri amagwiritsidwa ntchito pomanga zosanjikiza zomangira makoma akunja. Kugwiritsiridwa ntchito kwa HPMC mumtondo wakunja wotchinjiriza pakhoma kumawonekera makamaka pazinthu izi:
Kumamatira kowonjezera: Dongo lakunja lotchingira khoma liyenera kuphatikizidwa kwambiri ndi matabwa otchingira (monga EPS, matabwa a XPS, matabwa a ubweya wa miyala, ndi zina). HPMC ikhoza kupititsa patsogolo kumamatira pakati pa matope ndi zinthu izi kuti zitsimikizire kulimba ndi kukhazikika kwa wosanjikiza wotsekemera. kugonana.
Limbikitsani ntchito: Popeza matope otsekemera amatenthedwa nthawi zambiri amakhala ngati ufa wowuma, HPMC ikhoza kusintha madzi ake ndi zinthu zoyambira pambuyo powonjezera madzi, kuonetsetsa kuti matope amatha kugwiritsidwa ntchito mofanana panthawi yomanga ndipo sichikhoza kugwa kapena kusweka.
Limbikitsani kukana kwa ming'alu: M'mapulojekiti akunja otchingira khoma, kusintha kwakukulu kwa kutentha kungayambitse ming'alu. HPMC akhoza kusintha kusinthasintha kwa matope, potero mogwira kuchepetsa kuchitika kwa ming'alu.
2.3 Kugwiritsa ntchito mumatope osalowa madzi
Tondo lopanda madzi limagwiritsidwa ntchito makamaka poletsa madzi komanso mapulojekiti osagwirizana ndi chinyezi, makamaka m'malo omwe nthawi zambiri amalowetsedwa ndi madzi monga zipinda zapansi ndi mabafa. Kugwiritsa ntchito kwa HPMC mumatope osalowa madzi ndi motere:
Kusungidwa kwamadzi kowonjezera: HPMC imatha kukonza bwino kusungidwa kwamadzi mumatope, kupanga wosanjikiza wopanda madzi kukhala yunifolomu komanso wosasunthika, ndikuletsa madzi kuti asatuluke mwachangu, potero kuwonetsetsa kupanga ndi kumanga kwa wosanjikiza wosanjikiza madzi.
Limbikitsani kumamatira: Pomanga matope opanda madzi, kumamatira pakati pa matope ndi zinthu zoyambira ndizofunikira kwambiri. HPMC imatha kupititsa patsogolo kumamatira pakati pa matope ndi zida zoyambira monga konkriti ndi zomangira kuti ateteze wosanjikiza wosalowa madzi kuti asagwe ndi kugwa. .
Sinthani madzimadzi: Tondo lopanda madzi limafunikira kuti mukhale ndi madzi abwino. HPMC kumawonjezera fluidity ndi bwino workability kuti matope madzi akhoza wogawana kuphimba zinthu m'munsi kuonetsetsa kuti madzi.
2.4 Kugwiritsa ntchito mumatope odzipangira okha
Mtondo wodziyimira pawokha umagwiritsidwa ntchito pokweza pansi ndipo nthawi zambiri umagwiritsidwa ntchito pomanga pansi, kuika zinthu zapansi, ndi zina zotero.AnxinCel®HPMCmu matope odzipangira okha ndi awa:
Limbikitsani madzimadzi komanso kudziwongolera: HPMC imatha kusintha kwambiri madzi amadzimadzi odzipangira okha, ndikupangitsa kuti ikhale yabwinoko, ndikupangitsa kuti iziyenda mwachilengedwe ndikufalikira mofanana, kupewa thovu kapena malo osagwirizana.
Kusungika kwamadzi kowonjezereka: Tondo lodziyimira palokha limafuna nthawi yayitali kuti ligwire ntchito pomanga. Kusunga madzi kwa HPMC kumatha kuchedwetsa nthawi yoyambira matope ndikupewa zovuta zomangira chifukwa chowumitsa msanga.
Limbikitsani kukana kwa mng'alu: Tondo wodziyimira pawokha ukhoza kukhala ndi nkhawa panthawi yakuchiritsa. HPMC ikhoza kuonjezera kusinthasintha ndi kukana kwa matope ndi kuchepetsa chiopsezo cha ming'alu pansi.
3. Ntchito yonse ya HPMC mumatope
Monga chowonjezera chofunikira mumatope, HPMC imatha kupititsa patsogolo magwiridwe antchito ake posintha mawonekedwe akuthupi ndi mankhwala amatope. Mwa mitundu yosiyanasiyana ya matope, kugwiritsa ntchito HPMC kumatha kusinthidwa malinga ndi zosowa zenizeni kuti mukwaniritse ntchito yabwino yomanga ndikuchita kwanthawi yayitali:
Mu pulasitala matope, makamaka bwino workability, madzi posungira ndi adhesion wa matope;
Mu matope akunja otchinjiriza khoma, mphamvu yolumikizirana ndi zida zotchinjiriza imalimbikitsidwa kuti ipititse patsogolo kukana kwa mng'alu ndikugwira ntchito;
Mumatope opanda madzi, amawonjezera kusunga madzi ndi kumamatira, komanso amawongolera ntchito yomanga;
Mumtondo wodziyimira pawokha, umapangitsa kuti madzi asasunthike, kusungika kwa madzi komanso kukana ming'alu kuonetsetsa kuti zomangamanga zikuyenda bwino.
Monga chowonjezera cha polima chochita ntchito zambiri, AnxinCel®HPMC ili ndi chiyembekezo chokulirapo pantchito yomanga matope. Ndi chitukuko chosalekeza chaukadaulo wa zomangamanga, mitundu ndi ntchito za HPMC zipitilira kukonzedwa, ndipo gawo lake pakuwongolera magwiridwe antchito amatope, kukonza bwino ntchito yomanga, ndikuwonetsetsa kuti ntchitoyo ikhale yofunika kwambiri. M'tsogolomu, kugwiritsa ntchito HPMC pantchito yomanga kudzawonetsa njira yochulukirapo komanso yosiyana.
