Hydroxyethyl methylcellulose (HEMC), monga polima yosungunuka m'madzi yomwe imagwiritsidwa ntchito kwambiri, imakhala ndi maubwino ambiri pakupaka simenti. Kapangidwe kake kake kamalola kuti agwire ntchito yofunikira pakuwongolera magwiridwe antchito a simenti.
1. Kupititsa patsogolo ntchito yomanga
Panthawi yomanga zokutira zokhala ndi simenti, kusungunuka kwa madzi ndi kugwirira ntchito ndizofunikira zomwe zimakhudza ubwino wa zokutira ndi zomangamanga. HEMC ikhoza kupititsa patsogolo ntchito yomanga ya zokutira powonjezera kukhuthala komanso kusunga madzi kwa zokutira. Ntchito yeniyeni ndi:
Limbikitsani magwiridwe antchito a utoto: HEMC imatha kukulitsa kugwirizana kwa utoto, kupangitsa kuti ikhale yosavuta kuwongolera utoto panthawi yopaka ndikupewa zovuta monga kutulutsa utoto komanso kudontha.
Limbikitsani kusungirako madzi kwa zokutira: HEMC ikhoza kupititsa patsogolo kusungirako madzi kwa zokutira zopangira simenti, kuchepetsa kuthamanga kwa madzi a nthunzi, ndikuonetsetsa kuti zokutira ndizofanana komanso zokhazikika.
Izi ndizofunikira makamaka pazomangamanga zomwe zimafunikira ntchito yayitali. Zitha kuonetsetsa kuti slurry ya simenti siidzauma msanga panthawi yomanga nsabwe za m'masamba, motero kuonetsetsa kuti zokutira zili bwino.
2. Wonjezerani maola otsegulira
Nthawi yotseguka ya utoto wopangidwa ndi simenti ndi nthawi yomwe utoto utayikidwa kuti ukhoza kusinthidwa kapena kutha. Monga chowonjezera bwino, HEMC imatha kukulitsa nthawi yotsegulira zokutira zopangira simenti, motero kukulitsa kusinthika kwa zomangamanga. Pambuyo powonjezera HEMC ku zokutira zopangira simenti, ogwira ntchito yomanga akhoza kukhala ndi nthawi yochuluka yokonza zokutira ndi kudula kuti apewe mavuto omwe amadza chifukwa cha kuchira msanga.
3. Sinthani kumamatira kwa utoto
Mtengo HEMC imatha kupititsa patsogolo kumamatira pakati pa zokutira ndi gawo lapansi mu zokutira zopangira simenti, makamaka pamalo osalala kapena ovuta kulumikiza gawo lapansi (monga chitsulo, galasi, ndi zina). Kuphatikizika kwa HEMC kumatha kusintha kwambiri kumamatira kwa zokutira. Kuyikira Kwambiri. Mwa njira iyi, osati kukhazikika kwa zokutira kumangowonjezereka, komanso mphamvu yotsutsa-kugwa ya zokutira imakulitsidwa.
4. Sinthani kukana kwa ming'alu ya zokutira
Zovala zokhala ndi simenti zimatha kusweka panthawi yakuchiritsa, makamaka pazovala zolimba kapena m'malo otentha kwambiri. HEMC ikhoza kupititsa patsogolo kusungunuka kwa zokutira kudzera mu mawonekedwe ake apadera a maselo, kuchepetsa kuchepa kwa voliyumu chifukwa cha kusungunuka kwa madzi, ndi kuchepetsa kuchitika kwa ming'alu. HEMC imathanso kuyanjana ndi zigawo zina mu simenti kuti ipange mawonekedwe okhazikika a netiweki, kupititsa patsogolo kulimba komanso kukana kwa ming'alu.
5. Limbikitsani kukana kwamadzi kwa zokutira
Kukana kwamadzi kwa zokutira zotengera simenti ndikofunikira pakumanga kunja, zipinda zapansi, ndi madera ena omwe ali ndi chinyezi kapena madzi. Zomwe zimasunga madzi za HEMC zimatha kuchepetsa kutayika kwa madzi mu zokutira za simenti, motero kumapangitsa kuti madzi asamangidwe. Kuphatikiza apo, HEMC imatha kugwirizanitsa ndi zosakaniza mu simenti kuti ipititse patsogolo mphamvu yoletsa kulowa mkati mwa zokutira, potero kuwongolera magwiridwe antchito amadzi a zokutira.
6. Kupititsa patsogolo rheology ya zokutira
Kugwiritsa ntchito HEMC mu zokutira zopangira simenti kumatha kupititsa patsogolo kamvekedwe ka zokutira, ndikupangitsa kuti ikhale yamadzimadzi komanso yokhazikika. Pambuyo powonjezera HEMC ku zokutira zokhala ndi simenti, madzi amadzimadzi amadzimadzi pa nthawi yophimba amakongoletsedwa, ndipo pamwamba pake amatha kupanga chophimba chofewa komanso chofananira, kupeŵa zowonongeka zowonongeka chifukwa cha kukhuthala kwakukulu kapena kosagwirizana.
7. Kuchita kwa chilengedwe
Monga chotengera chachilengedwe cha polysaccharide,Mtengo HEMC ili ndi biodegradability yabwino motero ili ndi magwiridwe antchito abwino kwambiri a chilengedwe. Imatha kulowa m'malo mwa zowonjezera zamankhwala opangira ndikuchepetsa zinthu zovulaza mu zokutira, potero kuwongolera magwiridwe antchito achilengedwe a zokutira zokhala ndi simenti. Kwa zokutira zamakono zamakono, chitetezo cha chilengedwe chakhala cholinga cha msika ndi malamulo, kotero kugwiritsa ntchito HEMC kumagwira ntchito yabwino pakupititsa patsogolo chitetezo cha chilengedwe cha zokutira.
8. Sinthani kukhazikika kwa utoto
Kuphatikizika kwa HEMC kumatha kukulitsa kukana kuvala, kukana nyengo komanso kukana kwa UV kwa zokutira zokhala ndi simenti. Imatha kuchepetsa mavuto monga kutha ndi kung'ambika kwa zokutira zokhala ndi simenti chifukwa cha zinthu zachilengedwe zakunja monga kuwala kwa dzuwa ndi kukokoloka kwa mvula, ndikupangitsa kuti zokutirazo zikhale zolimba. Ubwinowu ndi woyenera makamaka kumanga zokutira kunja kwa khoma zomwe zimawonekera kunja kwa chilengedwe kwa nthawi yayitali ndipo zimatha kuwonjezera moyo wautumiki wa zokutira.
9. Limbikitsani antibacterial katundu wa zokutira simenti
Pamene zofunikira za thanzi ndi chitetezo cha zipangizo zomangira zikuwonjezeka, katundu wa antimicrobial mu zokutira akukhala muyeso wofunikira. HEMC palokha imakhala ndi antibacterial properties ndipo imatha kuteteza bwino kukula kwa nkhungu ndi mabakiteriya pamtunda wokutira. M'malo okhala ndi chinyezi chambiri, kuwonjezera kwa HEMC kumatha kuthandizira kuphimba kukana kukokoloka kwa nkhungu ndi bowa ndikuwongolera ukhondo ndi kukhazikika kwa zokutira.
10. Kupititsa patsogolo chitetezo cha zomangamanga za zokutira zopangira simenti
Monga mankhwala opanda poizoni komanso osakwiyitsa, HEMC ili ndi chitetezo chokwanira. Panthawi yomanga,Mtengo HEMCsichivulaza thupi la munthu ndipo imachepetsa mphamvu ya thanzi la ogwira ntchito yomanga. Kuphatikiza apo, HEMC imatha kuchepetsanso fumbi lomwe limapangidwa panthawi yomanga, potero kuwongolera mpweya wabwino wamalo omanga.
Kugwiritsa ntchito kwahydroxyethyl methylcellulosemu zokutira zokhala ndi simenti zili ndi zabwino zambiri. Sizingangowonjezera ntchito yomanga ❖ kuyanika, kukulitsa nthawi yotsegulira, ndikuwongolera kumamatira, komanso kumapangitsanso kukana kwa mng'alu, kukana madzi, rheology ndi kulimba kwa zokutira. Kuphatikiza apo, HEMC, monga chowonjezera chothandizira zachilengedwe komanso chopanda poizoni, sichimangowonjezera magwiridwe antchito, komanso imathandizira kuchepetsa zolemetsa zachilengedwe. Chifukwa chake, HEMC yakhala ikugwiritsidwa ntchito kwambiri pazoyala zamakono zokhala ndi simenti ndipo yakhala gawo lofunikira pakuwongolera bwino zokutira ndi zomangamanga.
