Hydroxypropyl Methyl Cellulose imakhudzanso mphamvu ya matope a simenti

Kumayambiriro kwa matope a simenti, hydroxypropyl methyl cellulose imatha kuchepetsa mphamvu. Ichi ndi chifukwa kuonjezera porosity wa matope kumlingo winawake ndi adsorb mbali ya madzi, potero zimakhudza yachibadwa hydration anachita ndondomeko simenti ndi kulepheretsa chitukuko cha oyambirira mphamvu kumlingo wakutiwakuti.

1. Kukhudza kwanthawi yayitali

M'kupita kwa nthawi, mphamvu ya hydroxypropyl methyl cellulose pa mphamvu ya matope a simenti ndizovuta kwambiri. Kumbali imodzi, zotsatira zake zosungira madzi zimatha kuonetsetsa kuti simenti ikupitirizabe kukhala ndi madzi kwa nthawi yaitali, kuti mphamvuyo ikhale yowonjezereka. Kumbali inayi, imatha kusintha kapangidwe ka mkati mwa matope, kukulitsa kukhazikika kwake komanso kukhazikika, komanso kukhala ndi zotsatira zabwino pamphamvu pamlingo wina.

Kawirikawiri, mphamvu ya hydroxypropyl methyl cellulose pa mphamvu ya matope a simenti si imodzi. Zinthu zingapo ziyenera kuganiziridwa mozama, ndipo kusintha koyenera ndi kuwongolera kuyenera kupangidwa malinga ndi momwe zinthu zilili pakugwiritsa ntchito.

Hydroxypropyl methyl cellulose (HPMC) imagwira ntchito yofunika kwambiri mumatope.

1. Ntchito

Kusunga madzi

1. Zingalepheretse madzi mumtondo kuti asatayike mwachangu ndikusunga matope kuti akhale ndi ntchito yomanga komanso yogwira ntchito kwa nthawi yayitali. Izi zimathandiza kuonetsetsa kuti matope sangagwedezeke ndipo mphamvu sizidzachepetsedwa chifukwa cha kutuluka kwa madzi mofulumira panthawi yopaka, kumanga ndi zina.
2. Kusungidwa bwino kwa madzi kumatha kulola simenti kukhala ndi nthawi yokwanira yochitira hydration, potero kumapangitsa mphamvu ndi kulimba kwa matope.

Kukhuthala katundu

1. Wonjezerani kukhuthala kwa matope kuti zikhale zosavuta kuti muzipaka mofanana panthawi yomanga ndikupewa kugwedezeka. Nthawi yomweyo, matope okhuthala amatha kumamatira bwino pamtunda ndikuwongolera kumamatira.
2. Zimathandizira kukulitsa kukana kwa sag ya matope. Makamaka pomanga pamakoma oyima kapena kudenga, zimatha kuwonetsetsa kuti matopewo asasunthike chifukwa cha mphamvu yokoka.

Limbikitsani magwiridwe antchito

1. Pangani matope kuti azigwira ntchito bwino komanso kuti azikhala osavuta kugwedezeka, kusuntha ndi kupanga. Ogwira ntchito amatha kupulumutsa khama kwambiri panthawi yogwira ntchito ndikupititsa patsogolo ntchito yomanga.
2. Zingathe kuchepetsa kuponyedwa ndi kuwononga matope panthawi yomanga ndi kusunga malo omangapo aukhondo.

Limbikitsani kulimba

1. Limbikitsani kupirira kwa chisanu ndi kusasunthika kwa matope. M'madera ozizira, HPMC imatha kuletsa madzi mumtondo kuzizira ndikukulitsa ndikuwononga kapangidwe kake; m'malo achinyezi, imatha kuteteza madzi kuti asalowe ndikuteteza nyumba kuti zisakokoloke.
2. Zimathandiza kuchepetsa kuchepa ndi kung'ambika kwa matope ndikutalikitsa moyo wautumiki wa nyumba.

1. Kusamala kuti mugwiritse ntchito

Kuwongolera mlingo

1. Mlingo wa HPMC uyenera kusinthidwa molingana ndi zinthu monga mtundu wa matope, zofunikira zomanga ndi chilengedwe. Nthawi zambiri, mlingo wochepa kwambiri sungathe kugwira ntchito yake, pamene mlingo wochuluka ukhoza kukhudza mphamvu ndi zina za matope.
2. Pogwiritsira ntchito, mlingo woyenera kwambiri ukhoza kudziwitsidwa mwa kuyesa.

Kusakaniza yunifolomu

1. Powonjezera HPMC, ziyenera kuwonetseredwa kuti zagwedezeka mokwanira kuti zizitha kusewera bwino mumatope. Kukondoweza kumakina kungagwiritsidwe ntchito, ndipo nthawi yosonkhezera isakhale yaifupi kwambiri.

Zosungirako

1. HPMC iyenera kusungidwa pamalo owuma ndi mpweya wokwanira kupewa chinyezi komanso kuwala kwa dzuwa. Kutentha kosungirako sikuyenera kupitirira 30 ° C kuti zisakhudze magwiridwe ake.
2. Posungira ndikugwiritsa ntchito, chidwi chiyenera kuperekedwa popewa kukhudzana ndi mankhwala ena kuti mupewe zovuta.
