Makhalidwe a HPMC mu matope owuma

Mu matope owuma, hydroxypropyl methl cellulose (hpmc) amagwiritsidwa ntchito kwambiri. Kugwiritsa ntchito kwa matope owuma kumakhudza kwambiri ntchito yomanga, kusungidwa kwamadzi, kugwiritsidwa ntchito, kusokonekera kwa matope ndi zinthu zina mwa matope. Kuchita bwino kwambiri kwa HPMC kumapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri popanga zida zomangira, makamaka mu matope owuma, pomwe imakhala ndi gawo lofunikira.

1. Zotsatira za kukula
HPMC ili ndi kukula kwakukulu, kulola matope owuma kuti akwaniritse bwino pomanga. HPMC imapanga njira yokhazikika ya viscous mutatha kusungunuka m'madzi, zomwe zimawongolera mwayi wogwiritsa ntchito ndi anti-sag-sag - kapangidwe ka sayansi powonjezera matope. Pomanga zomanga monga kupatsirana ndi matayala, kukana kwabwino kwa salg kumapangitsa kuti matonthowo agawidwe kukhosi ndipo pewani kutsikira chifukwa cha mphamvu yokoka. Nthawi yomweyo, kukula koyenera kumathanso kuyendetsa madzi ndi makulidwe a matope, kukonza zolondola zomanga.

2. Kusunga kwamadzi
Khalidwe lofunikira la HPMC mu matope owuma ndi malo ake osunga madzi abwino. Popeza HPMC ili ndi hydrophilicity yabwino ndi manyowa amadzi, imatha kuyamwa mwaluso ndikusunga chinyezi. Kusungidwa kwamadzi kwamtunduwu ndikofunikira kwambiri pa matope owuma, chifukwa pamalo owuma, makamaka kutentha kwambiri komanso chinyezi cham'madzi ndikosavuta kuwunika madzi ndi kugwirira ntchito zomwe zili pasadakhale, zomwe zikukhudzanso mphamvu pambuyo pake. mawonekedwe. HPMC imatha kukulitsa nthawi ya madzi, potero kuonetsetsa kupita patsogolo kwambiri kwa ma simenti a simenti. Kuphatikiza apo, kusungidwa kwamadzi kumathanso kuchepetsa kupezeka kwa ming'aluyo ndikupewa ming'alu yocheperako m'matope.

Kugwira ntchito kumatanthauza kuthekera kwa matope owuma nthawi yosakanikirana ndi ntchito yomanga. HPMC imatha kusintha kwambiri matope, ndikupangitsa kuti zikhale zosavuta kuyambitsa matopewo komanso kuchepetsa ulamuliro pomangidwa. Kanema wopaka mafuta wopangidwa ndi HPMC mu matope amapangitsa matope kukhala osakanikirana ndikugwiritsira ntchito, kuthandiza kuchepetsa zovuta zomanga. Kuphatikiza apo, kapangidwe ka HPMC kumathandizira kusintha madzimadzi, ndikupangitsa kuti ikhale yosavuta kufala, potengera luso la ntchito.

4. Sinthani kukana kukana
Ming'alu yoyambitsidwa ndi kuyanika ndi vuto lomwe lili m'matayala, ndipo madzi osasunga a HPMC amathandizira kupezeka kwa ming'aluyo. Mwakutalikira nthawi yopanduka ya madzi m'toto, hpmc imatha kuchepetsa nkhawa zomwe zimachitika chifukwa cha kuchepa kwa madzi kwadothi. Kuphatikiza apo, kusintha kwakukulu kwa HPMC kumatha kukonzanso mphamvu yakutonthoza kwa matope, potero kumalimbikitsa kukana kwa matope. Izi zotsutsa-zotsutsa zimagwira gawo lofunikira pakuchepetsa kukonzanso ndi kukonzanso m'gawo limodzi momanga.

5. Kusintha Kulimbana Kwaku Freeze-Thaw
HPMC imathandizanso kukonza matope owuma. M'malo omanga ozizira, chinyezi mu matope a simenti chitha kuwaza, ndikuwononga mawonekedwe amkati mwa matope. Kusungidwa kwamadzi komanso kukula kwa HPMC kungachepetse mphamvu ya matope a Freeze-Thaw pamlingo wina. Zimachepetsa kuwonongeka kwa matope omwe amayamba chifukwa cha kuzizira ndi kufulumira kwamadzi nthawi ya freeze-thaw pochepetsa madzi aulere m'matope.

6. Sinthani chosalala
Kupatuka ndikukhazikitsa matope, hpmc amathanso kusintha mosalala komanso kufanana kwa nkhope ya matope. Kukula kwamphamvu ndi madzi osungidwa ku HPMC kupanga matonthowo kumapangitsa kuti chivundi chikhale chofananira nthawi yopuma ndikuchepetsa kukhazikika kwa dothi. Kwa mankhusu omwe amafuna zapamwamba, monga mkati mwa khomo lolowera khoma, pansi, etc., kugwiritsa ntchito HPMC kumatha kukonza ntchito yopukutira.

7. Sinthani nthawi yotseguka ya matope
Panthawi yomanga, nthawi yotseguka ya matope yowuma ndiyofunikira kuti antchito agwire ntchito. Nthawi yotsegulira ikunena za nthawi yomwe matopewo itayikidwa komanso pomwe matope amayamba kutaya mphamvu yake. Kusunga kwamadzi kwa HPMC kumachepetsa kuchuluka kwa madzi mu matope, kumapitirira nthawi yotseguka kwa matope, ndikuwonjezera kusinthasintha kwa ogwira ntchito panthawi yomanga, makamaka pamachitidwe ogwirira ntchito.

8. Kupititsa patsogolo mphamvu
HPMC imatha kusintha bwino kulimba kwa matope owuma, makamaka m'matate a ceramic tiles. Kapangidwe ka polymer kopangidwa ndi HPMC mu njira yamadzi am'madzi kungalimbikitse chigoba chamkati cha matope, motero kumawongolera chipilala cha matope a matope. Kusintha kumeneku ndikofunikira kwambiri pakugwiritsa ntchito kofunikira kulimbikira kwambiri monga zomata za matayala ndi mafuta opindika.

Monga chowonjezera chowuma cha matope, chopota cha HPMC, kusunthika kwamadzi, kukhazikika ndi zina zambiri kukonzanso matope owuma ndipo ndioyenera kusiyanasiyana kangana.
