Zotsatira za hemc hydroxyethyl methl cellulose pa simenti hydration

Hemo Amakhala ndi gawo pakuwongolera madzimadzi amakatira ndikuchedwetsa ma simenti hydrate. Mu mankhwala hydration a simenti, hemoc ali ndi chidaliro china pa chithandizo chamankhwala chamankhwala komanso simenti.

1. Zoyambira za hemc
Hemc ndi polymer wopangidwa ndi kusintha kwa mankhwala a cellulose. Kapangidwe kake kazithunzi kumakhala ndi magalamu awiri, hydroxyethyl ndi methyl, omwe amapangitsa kuti akhale ndi kuthekera bwino, kusinthika kwa mavidiyo ndikupanga mafilimu. Monga kuphatikizika kwa simenti, hemoc kumatha kusintha madzimadzi ake, zomangamanga, ndi kubisala, mu phala la simenti, ndipo amatha kusintha mphamvu ndi kukhazikika pambuyo polimba mtima.

2. Zotsatira za hemc pa simenti hydraction njira
Mafuta a simenti ndi njira ya simenti ndi matenda. Kudzera mu izi, phala limayang'ana pang'onopang'ono matrix olimba. Monga kuphatikizika, hemac amathanso kusewera maudindo osiyanasiyana mu simenti njira. Zotsatira zake ndi izi:

2.1 Kukonza madzimadzi a simenti slorry
Kumayambiriro kwa simenti hmenti, madzi a simenti sakhala osauka, omwe angakhudzidwe pomanga. Hemc imatha kusintha madzimadzi olekanitsidwa chifukwa cha maonedwe ake ndi kusungunuka kwa madzi abwino. Imabalalitsa tinthu tating'onoting'ono tambiri ndikuchepetsa kusokoneza pakati pa tinthu tambiri, potero kumawonjezera kusasinthika kwa simenti slorry, kumapangitsa kukhala kosavuta kugwira ntchito ndikutsanulira pomanga.

2.2 Chemement Stement hydrate
Gulu la hydroxyethyl mu hemoc lili ndi mphamvu yamphamvu. Itha kupanga filimu ya hydration pamwamba pa simenti tinthu, ndikuchepetsa kuthamanga pakati pa tinthu tambiri tinthu tambiri tinthu tating'onoting'ono ndi madzi. Kusintha kumeneku ndikofunikira makamaka kutentha kwambiri kapena zomangamanga mwachangu. Itha kupewa kukula kwamphamvu chifukwa cha hydration wa simenti, ndipo imatha kuwonjezera nthawi yomanga kuti isavutitse mavuto.

2.3 Kukonzanso kukhazikika kwa simenti slorry
Panthawi yamavuto a simenti slorry, hemc imatha kukonza bwino kukhazikika kwa slurry. Magulu a hydroxyethyl ndi methyl molekyu ya hemc amatha kuyanjana ndi mitengo ya simenti kudzera pamalanda a hydrogen ndi van der walker kuti apange kapangidwe kake. Kukhazikika kumeneku kumathandizira kupewa stratization pasti, potero kumawonjezera kufanana kwa simenti ya simenti ndikuonetsetsa kukhazikika kwa njira ya simenti.

2.4 Kuwongolera microstructuctuctuctuctustection
Hemc imatha kukonza microstructuction ya zinthu zothandizira simenti posintha madzimadzi ndi mafayilo a phala phala. Mwachitsanzo, mu gawo la pambuyo pake la simenti hydration, hemc limatha kusokoneza mapangidwe ndi magawidwe azogulitsa ma cementi mu smentium caltery (CSH) Gel. Panthawi ya simenti, mapangidwe a CSH gel gel ndi chinthu chofunikira kudziwa mphamvu ndi kulimba kwa simenti. Momic imatha kulimbikitsa kugawa yunifolomu ya CSH geel ndikusintha kachulukidwe ndi kulimba kwa simenti posintha aion kukhazikika pakuchita kwa simentart hydration.

2.5 Zotsatira za mphamvu ya simenti
Mphamvu ya hemo pa simenti imagwirizana kwambiri ndi simenti. Kumayambiriro kwa simenti hmentation, mphamvu yoyambirira ya simenti imachepa kwambiri chifukwa cha kubwezeretsa kwa hemc. Komabe, monga momwe simenti ya ma simenti ya sime imapitilira, hemoc amatha kupanga mawonekedwe a simenti a simenti, potero amalimbikitsa kulimba mtima kwa pulanga pakuchiritsa. Kuphatikiza apo, hemc imatha kukonza zolimba za simenti, zimawonjezera ungwiro kwa simenti, ndikusintha baramenti.

3. Zotsatira zina za hemc pa simenti
Kuphatikiza pa zomwe zatchulidwazi pamwambapa pa simenti njira, hemc zimabweretsanso zovuta zina pa simenti, makamaka kuphatikiza:

3.1 Kupititsa patsogolo chisanu ndi kufooka kwa simenti
Hemo amatha kukonza microstructuction simenti, kuti ipangitse matrix a simenti a simenti. Kapangidwe kameneka kamatha kuchepetsa nkhawa mkati mwa simenti, poti apange chisanu kukana ndi kufooka kwa simenti. Panthawi yovuta kwambiri, kukana chisanu ndi kupanda ungwiro kwa kapangidwe ka sikofunika kukhazikika kwakanthawi kokhazikika kwa nyumba.

3.2 Kuwonjezera Kukana kwa Simenti
Popeza Hemoc amasintha kachulukidwe ka mmero, umathanso kuchepetsa kukhalapo kwa ma porement mkati mwa siranti, kuchepetsa kulowa kwa madzi, mpweya kapena mankhwala, ndikuwongolera kuwonongeka kwa simenti. Makamaka m'malo onyowa kapena acid-acid, hemoc amatha kuthandiza kukulitsa moyo wa ntchito ya simenti.

4. Kuchuluka ndi zotsatira za hemc
Zotsatira za kuchuluka kwa hemoc pa simenti hydration njira ndi chinthu chofunikira. Nthawi zambiri, kuchuluka kwa hemoc adawonjezera kuyenera kusinthidwa malinga ndi zosowa zenizeni. Hemc yochuluka imatha kuyambitsa simenti kuti ikhale yovuta kwambiri ndikukhudza ntchito yomanga; Ngakhale kuti sizabwino zowonjezera sizingasewerere mbali yake pokonza simenti. Nthawi zambiri, kuchuluka kwa hemc kuwonjezeredwa kwa simenti ndi 0,2% mpaka 1.0% (ndi simenti

Monga kuphatikizika kwa simenti, hemac amatenga gawo lofunikira pakusintha madzimadzi a Slomer, atacheza ndi simenti hydratection njira, ndikuwongolera microption sime. Kugwiritsa ntchito moyenera hemc kumatha kukonza magwiridwe antchito mpaka pamlingo wina, makamaka kukonza bata, kukulitsa nthawi yolerera, komanso kulimbikitsa mphamvu ndi kukhazikika kwa simenti yolimba. Komabe, kuchuluka kwa hemo. Pomanga, kugwiritsa ntchito hemc kumathandizira kukonza bwino komanso kukhazikika kwa zinthu za simenti.
