Zotsatira za HPMC pa kusungidwa kwamadzi ndikupanga matope a simenti

Hydroxypropyl methylcellulose (hpmc)ndi polymer osungunuka wamadzi nthawi zambiri amagwiritsidwa ntchito pomanga. Amagwiritsidwa ntchito kwambiri pa matope a simenti, putty ufa, zomatira matamandi ndi zinthu zina. HPMC imasintha zinthu zabwino za simenti pochulukitsa mamasukidwe a dongosololi, kukonza njira yosungitsa madzi ndikusintha magwiridwe antchito.

1. Zotsatira za hpmc pa madzi osungira matope a simenti
Kusunga kwamadzi kwa matope a simenti kumatanthauza kuthekera kwa matope kuti asunge madzi asanakhazikitsidwe. Kusungidwa kwabwino kwamadzi kumathandiza kuti simenti yonse komanso imalepheretsa kusokonekera ndi kuwonongeka kwamphamvu chifukwa cha kutaya madzi kwambiri. HPMC imathandizira kuti matope a simenti mu njira zotsatirazi:

Kuchulukitsa mafayilo
Pambuyo pa HPMC imasungunuka mu matope a simenti, imapanga mawonekedwe a yunifolomu, imawonjezera mawilo a matope, amagawana madzi mkati mwa matope ndikuchepetsa kutayika kwa madzi aulere, potero kukonza madzi aulere. Izi ndizofunikira makamaka pakupanga kutentha kwambiri kumalimwe kapena zigawo zokhala ndi mayamwidwe amphamvu.

Kupanga chotchinga chinyezi
Mamolekyu a HPMC ali ndi mayamwidwe olimba, ndipo yankho lake limatha kupanga filimu ya hydration mozungulira tinthu tating'onoting'ono, zomwe zimapanga gawo lopindika madzi ndikuchepetsa madzi osintha ndi mayamwidwe. Filimu yamadziyi imatha kupitilira matope mkati mwa matope, kulola kuti ma sime hydrate hydrate apitirize bwino.

Kuchepetsa magazi
HPMC imatha kuchepetsa magazi a matope, ndiye kuti, vuto la madzi kuwombera matope ndikuyandama pambuyo pa matope atasakanikirana. Powonjezera ufawu komanso mawonekedwe am'madzi am'madzi, hpmc imatha kulepheretsa kugawa madzi mu matope, ndikuwonjezera matope athunthu.

2. Mphamvu ya HPMC pa kapangidwe ka simenti
Udindo wa HPMC mu matope sikuti ndi kusungidwa kwamadzi, komanso kumakhudzanso kapangidwe kake, monga tikuwonetsera pansipa:

Akukhudza njira ya simenti
Kuphatikiza kwa hpmc kumachepetsa ma hydration hydration hydration koyambilira, ndikupanga mapangidwe a ma hydrate zinthu zambiri yunifolomu, zomwe zimapangitsa kuti pakhale matope. Kuchedwa kumeneku kumatha kuchepetsa kuchepa kwadzidzidzi ndikuwongolera kukana kwa matope.

Kusintha zopangira zam'matontho
Mukatha kusungunula, hpmc imatha kuwonjezera matope ndi kugwirira ntchito matope, ndikupangitsa kuti ikhale yosavuta panthawi yogwiritsa ntchito kapena kugona, komanso kuchepa magazi ndi tsankho. Nthawi yomweyo, hpmc imatha kupereka matootropy yina, kuti ikhale yowoneka bwino kwambiri mukayimirira, ndipo madziwo amalimbikitsidwa pansi pa ntchito yomanga, yomwe ndi yothandiza pakumanga.

Kupangitsa kukulitsa mphamvu kwa matope
Ngakhale HPMC imathandizira matope a matope, zingakhalenso zovuta pa mphamvu yake yomaliza. Popeza HPMC ipanga filimu mu matope a simenti, zitha kuzengereza mapangidwe azogulitsa hydration m'nthawi yochepa, ndikupangitsa mphamvu kuti ichepetse. Komabe, pamene simenti hydrate ikupitilira, chinyezi chosungidwa ndi HPMC chitha kulimbikitsanso zomwe zimachitika pambuyo pake, kuti mphamvu zomaliza zitha kusintha.

Monga chowonjezera cha matope a simenti,HpmcItha kusintha bwino madzi osungira matope, kuchepetsa kuchepa kwamadzi, sinthani magwiridwe antchito, ndikukhudza simenti hydrate njira zina. Posintha mlingo wa HPMC, yabwino kwambiri pakati pa kusungidwa kwamadzi, kugwiritsidwa ntchito ndi mphamvu zitha kupezeka kuti mukwaniritse zosowa za prenarios yosiyanasiyana. Pomanga, kugwiritsa ntchito kwa HPMC ndikofunikira kwambiri kukonza matoma ndi kukulitsa.
