Kwa simenti tlickener hpmc hydroxypyllfel

Hydroxypropyl methylcellulose (hpmc) ndi gawo losiyanasiyana lomwe limagwiritsidwa ntchito ngati simentaner mu mafakitale osiyanasiyana. Ndi malo ake apadera ndi ntchito zake zapadera, hpmc imachita mbali yofunika kwambiri yolimbikitsira ntchito ndi mtundu wazogulitsa za simenti.

1.Ccharaction of HPMC:

Kapangidwe ka mankhwala: hpmc ndi ether celluse yochokera ku cellulose, zachilengedwe. Amapangidwa ndi kuchiritsa cellulose ndi ma propylene oxide ndi methyl chloride.
Zachilengedwe: hpmc ndi hydrophilic kwambiri, kutanthauza kuti amatenga madzi ndikugwiritsa ntchito madzi. Katunduyu ndi wofunikira chifukwa cha udindo wa simenti, chifukwa umathandiza kusungidwa kwamadzi mu materix.
Kutha Kwakukulu: HPMC imawonetsa bwino kwambiri zinthu zomwe zimabalalitsidwa m'madzi. Imapanga njira yosinthira yomwe imasangalatsa kwambiri simenti, matope, ndi zida zina zomanga.
Mapangidwe a filimu: Pouma, hpmc amapanga mawonekedwe owonekera, osinthika, komanso ogwirizana. Kanemayo amachita ngati chotchinga, kukonza zomatira, kukana madzi, ndi kulimba kwa zinthu zopangidwa ndi simenti.
Khalidwe lokhazikika: HPMC imakhazikika pamawu ambiri, ndikupangitsa kuti zigwirizane ndi mapangidwe osiyanasiyana a simenti ndi mikhalidwe yomanga.

2.Paplictictions ya HPMC mu STEAME YOPHUNZITSIRA:

Tile zomata za Tile: HPMC imagwiritsidwa ntchito ngati thickiner mu ma tile omatira tile kuti musangalale, kutsatira, ndi kukana kwa sayansi. Zimawonjezera mphamvu yolumikizana pakati pa matailosi ndi magawo, ndikuwonetsetsa kukhazikitsa kosatha.
Matope: M'miyeso mavalo, hpmc amakhala odzisintha a rhelogy, kuwongolera mafakisoni ndikuletsa tsankho. Zimalimbikitsa kugawa yunifolomu ya ophatikizika, kumawonjezera kupatulidwa, ndikuchepetsa ming'alu yochepa.
Zodzikongoletsera zodzipangitsa: HPMC imadzipangitsa kuti ikhale yodzilimbitsa nokha kuti mudzichepetse zinthu zodzichepetsera, kuwongolera osalala komanso ngakhale pamalo. Imakhala bwinonso, imachepetsa zolakwika zapamwamba, ndikuwonjezera kumaliza.
Maulanje: HPMC imagwiritsidwa ntchito popanga ma prout kuti musinthe ma visction ndi kupewa kutsuka kwa tinthu tambiri. Ikuwonetsetsa kuti zodzaza ndi zokhumba, zimawonjezera chilulu, ndipo timachepetsa nthawi yovuta pakuchiritsa.
Kutulutsa kunja ndikumaliza ma Services (mabungwe a HPMC-vpm amagwiritsidwa ntchito pokana ndi nyengo yanyengo, kuthekera kovuta kwambiri, komanso chidwi chowoneka bwino. Zovala izi zimapereka chotetezera pamiyala yosasunthika, kukonza mphamvu ndi kulimba.

3.beneffets ogwiritsa ntchito hpmc ngati simenti ya simenti:

Kugwiritsa Ntchito Kugwirira Ntchito: HPMC imapereka bwino kwambiri kuyenda ndi kufalikira kwa simential mabulolemu, kulimbikitsa kugwira ntchito komanso kusavuta kugwiritsa ntchito.
Modelion Wowonjezera: Kapangidwe ka kama filimu ya HPMC kumathandizira kulimba mtima pakati pa zinthu za Cememention ndi magawo, zomwe zimapangitsa kuti zikhale zokhazikika komanso zokhazikika.
Kusunga kwamadzi: HPMC imasintha kwambiri kusanja kwamadzi mkati mwa mikangano yamapiko, kuchepetsa kuchepa kwamadzi kudzera mu kusintha ndikuwonetsetsa hydration yosiyanasiyana.
Kuchepetsa shrinkage: Mwa kuwongolera madzi osinthika ndikuwongolera coutheon, hpmc kumathandizira kuchepetsa ming'alu yovuta kwambiri pazida zochirikiza cemingsi, kulimbitsa umphumphu wawo.
Kusiyanitsa: HPMC imatha kuphatikizidwa mosavuta m'malo osiyanasiyana opangidwa ndi simenti, kupereka kusinthasintha ndikusintha magwiridwe antchito.

4.Kusintha kogwiritsa ntchito HPMC:

Mlingo woyenera wa HPMC zimatengera zinthu monga mtundu wa simenti, zomwe mukufuna kusintha, komanso zofunika kugwiritsa ntchito. Ndikofunikira kuchita mayesero kuti mudziwe kuchuluka koyenera kwa mitundu inayake.
Njira yosakanikirana: Kubala koyenera kwa HPMC ndikofunikira kuti mukwaniritse zofuna kukula. Iyenera kuwonjezedwa pang'onopang'ono m'madzi osakanikirana pomwe mukusunthira mosalekeza kuti mupewe mapangidwe a bump.
Kugwirizana: HPMC imatha kulumikizana ndi zowonjezera zina zomwe zimapezeka mu simenti. Mayeso ogwirizana ayenera kuchitika kuti atsimikizire kukhazikika ndi ntchito yomaliza.
Zinthu Zachilengedwe: Kutentha kozungulira ndi chinyezi kumatha kusokoneza magwiridwe antchito a HPMC. Maganizo apadera angafunikire nthawi yotentha kapena yowuma kuti ithetse kuyanika koyambirira komanso kusweka.
Kusungirako: HPMC iyenera kusungidwa pamalo ozizira, owuma kutali ndi dzuwa ndi chinyezi. Malo osungira bwino amathandizira kukhalabe ndi moyo wabwino komanso wa alumali.

HPMC ndi yowonjezera yofunika kwambiri yothira zinthu zochulukitsa za mmenga, kupereka mapindu ambiri monga kugwirira ntchito bwino, kutsatira madzi, kusungunuka kwamadzi, komanso kulimba. Mwa kumvetsetsa mawonekedwe ake, mapulogalamu, mapindu, ndi malingaliro, opanga komanso akatswiri omanga angathe kukonzekera kuthekera kwa HPMC kuti ikwaniritse magwiridwe antchito ndi mawonekedwe awo.
