Hydroxypropyl methylcellulose (hpmc) ndi ma celluuse embic pompano omwe amagwiritsidwa ntchito kwambiri pomanga zomangira, chakudya, mankhwala opangira mankhwala ndi mankhwala a tsiku ndi tsiku. Ku Concerete, hpmc, monga owonjezera, amakhala ndi ntchito zambiri zapadera komanso zabwino ndipo zimatha kusintha konkriti.
Udindo wa HPMC mu konkriti
1. Sinthani kugwirira ntchito konkriti
Chimodzi mwazinthu zazikulu za HPMC ndikuwongolera kugwiritsidwa ntchito kwa konkriti, ndiye kuti, kumasuka kugwira ntchito ndi madzi. HPMC ili ndi mphamvu yabwino ndipo imatha kuwonjezera mafayilo a simeri, ndikupangitsa kukhala kosavuta kufalitsa ndi kupanga pomanga. Kuphatikiza apo, HPMC imatha kupititsa patsogolo madzi osalala a konkriti, kupewetsa madzi otentha kwambiri pansi pa kutentha kwambiri kapena kuyanika kwa mpweya, ndikusunga ma conclutity.
2. Thandizo la madzi osungirako konkriti
HPMC imatha kusintha madzi kolondola. Izi ndichifukwa choti hydroxyl magulu a methocy ku mabatani a HPMC ali ndi mayamwidwe amphamvu, omwe amatha kuyamwa ndikusunga madzi ndikuchepetsa kuchepa kwa madzi. Zotsatira za madziyi ndizofunikira kwambiri kuti ma conrete a konkriti, makamaka m'malo owuma, kuti ateteze ming'alu ya konkriti ndikuwonetsetsa kuti ma vanifolomu ndikukula konkriti.
3. Kuwongolera kukana kwa konkriti
HPMC imatha kusintha madzi opumira konkriti ndipo imalepheretsa madzi mwachangu, potero kuchepetsa ming'alu yofewa yoyambitsidwa ndi kutaya kwamadzi. Kuphatikiza apo, zotsatira za kukula kwa hpmc zimathandizanso kuchepetsa tsankho komanso magazi a scerete slowry, kuphatikiza kupezeka kwa ming'alu. Makamaka m'matumba a sikete kapena magetsi ambiri, kutentha kwambiri, zotsatira za anti-zotsutsa za HPMC ndizofunikira kwambiri.
4. Sinthani zitsamba za konkriti
HPMC imatha kukonza katundu wogwirizira konkriti ndi magawo osiyanasiyana. Izi ndichifukwa choti colloidal chinthu chopangidwa ndi HPMC kusungunuka m'madzi imatha kupanga filimu yopyapyala pamwamba pa konkriti kuti ipititse patsogolo mphamvu yolumikizirana ndi konkriti ndi zida zina. Izi ndizofunikira makamaka pazomwe zili ngati maphete ndi zomata za matayala, zomwe zimathandizira kulimbitsa thupi ndi kulimba.
5. Sinthani nthawi yokhazikitsa konkriti
HPMC ili ndi ntchito ina yowongolera nthawi. Malinga ndi zosowa, posintha kuchuluka kwa HPMC yowonjezeredwa, nthawi yokhala konkriti imatha kukulitsidwa kapena kufupikitsa, zomwe zimathandizira ntchito yomanga ndi kuwongolera patsogolo. Izi ndizofunikira kwambiri pamene zomangamanga zimafuna nthawi yayitali kapena kutentha kwambiri. Zimatha kupewa kumeterera kukhazikika mwachangu komanso kutsimikizira kukhala mkhalidwe womanga.
6. Sinthanitsani ku Freeze-Thaw kukana konkriti
Kusungidwa kwamadzi komanso kukula kwamphamvu kwa hpmc kumatha kusintha konkriti komwe ndikupanga, poyankha potengera kuzizira kwa konkriti. M'madera ozizira kapena mapulojekiti omwe amafunikira kuthana ndi zibowo za ku Freeze-thaw, kuwonjezera hpmc kumatha kupewa kuwonongeka ndikuwonongeka kwa konkriti komwe kumayambitsidwa ndi ming'alu yaulere ndikuwonjezera moyo wake.
Kugwiritsa ntchito HPMC mu konkriti
HPMC imagwiritsidwa ntchito kwambiri ku konkriti, makamaka pankhani izi:
1. Kusakaniza matope owuma
Mu matope osakanikirana, osakanizika a HPMC akhoza kusintha madzi osungidwa ndi matope, kuletsa madzi kuti asakane mwachangu, ndikuwongolera mphamvu yomanga. Kuphatikiza apo, HPMC imathanso kusintha kukana kwa matope ndikuwonjezera moyo wake wantchito.
2. Tile zomatira
Kuonjezera HPMC ku Tile ku Tile kuthandizira kuwoneka komwe kumapangitsa kuti mamasukidwe awo komanso mphamvu yolumikizana, onetsetsani kuti matailosiwo siosavuta kungoyenda ndikugwa nthawi yochepa. HPMC imatha kukonzanso chitetezo chamadzi komanso kupindika kwa matayala a ceramic tiles kuchokera kuwonongeka chifukwa cha kuchepa kwa madzi kapena kuchepa kwa madzi kapena zouma.
3. Kutayika matope
Pa matope opakata, hpmc imatha kusintha madzimadzi, ndikupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndi mawonekedwe pomanga, kuchepetsa zovuta zomanga. Nthawi yomweyo, hpmc amathanso kukulitsa kusokonekera kwamitundu ndi mphamvu ya matope kuti zitsimikizire kuti sizabwino komanso zolimba za pulasitiki.
4.. Pansi
Pakati pa zinthu zodzipangira pansi, hpmc zimatha kusintha madzima ndi kusungidwa kwake, onetsetsani kuti zinthu zapakhomo zitha kudzidalira pomanga, ndikuchepetsa zolakwika zomanga komanso zapamwamba. Kuphatikiza apo, hpmc amathanso kukulitsa kukana ndikuvala kukana zinthu pansi, kusintha moyo wawo wautumiki ndi zokopa.
Kugwiritsa ntchito hydroxypypyl methylcellulose (hpmc) ku konkriti kumakhala ndi zabwino zambiri ndipo kungakuthandizeni kwambiri, kusungidwa kwamadzi, kuphwanya ndi kuwuma kwa konkriti. Mwa kuwonjezera ndi kugwiritsa ntchito hpmc, mtundu womanga ndi kulimba kwa konkriti ungakonzekere kukwaniritsa zosowa zambiri zaukadaulo. M'tsogolomu, popititsa patsogolo ntchito za ukadaulo komanso kupititsa patsogolo ntchito mosalekeza, udindo wa HPMC ku konkriti udzakhala wofunika kwambiri, kubweretsa zachuma komanso chikhalidwe chawo.
