Zotsatira za hydroxethyl methl cellulose pazinthu za simenti

Hydroxyethyl methy cellose (hemc) ndi matope a simenti omwe amagwiritsidwa ntchito popanga ntchito zomanga. Ndi malo osungunuka osungunuka a polymer omwe adakhazikitsidwa ndi kusintha kwa mankhwala kwa cellulose. Kugwiritsa kwa hemc mu matope a SETRE kumathandizira kugwirira ntchito matope ndi matope amatope mwakusintha kwa matope a matope (monga madzi, kusungidwa kwamadzi, ndi zina).

1. Sinthani madzi amtundu wa simenti
Monga thicker, hemc imatha kusintha madzimadzi atawonjezeredwa matope a simenti. Mphamvu yake yochitapo makamaka ikuwonjezera kuyanja kwa simenti yotsika ndi mafoni am'madzi ndi zinthu zina mu simentant matrix, potero kukonza madzimadzi. Madzi a matope ndi abwino, sikovuta kugwiritsa ntchito ndi kukhala ndi mwayi pomanga, komanso amatha kupewa kukhazikika kapena kukhazikika kwame simenti, ndikuwongolera luso la kumanga ndi mtundu.

2. Sinthani mafayilo a matope
Hemc imakhala ndi madzi olimba. Pambuyo powonjezera matope a simenti, matope a matope adzatukuka. Kuchulukitsa kumathandizira kukonza matope omanga matope, makamaka pomanga matope owongoka, kuteteza matope kuchokera pansi kapena kugwa. Kuphatikiza apo, maonekedwe ochulukitsa a hemac nawonso amatenga mbali moyenera posintha matope a matope mu matope okwera kapena otsika nthawi yake.

3. Kulimbikitsa madzi osungira matope a simenti
Hemc imatha kusintha bwino madzi osungira matope a simenti, omwe ndi gawo lofunikira pakugwiritsa ntchito kwake popanga zomanga. Kusunga kwamadzi ndi chinthu chofunikira cha matope a simenti chomwe chimapangitsa madzi kukhala osasinthika pomanga. HemC imapanga filimu yoteteza kuti muchepetse madzi otetezedwa ndikusunga zonyowa mwachangu, popewa kuwuma msanga kwa simenti, ndikupewa kuwuma msanga kwa simenti, ndikuwonjezera nthawi ya matope a simenti kuti awonetsetse kuti ndalama zade.

4. Sinthani mikhalidwe yazikhalidwe za rheological
Pambuyo pa hemc amawonjezeredwa matope a simenti, curlogical curve akuwonetsa mawonekedwe a madzi osakhala achi Newtonia, ndiye kuti, mafayilo a matope ndi kusintha kwa mitsinje. Mawonekedwe owoneka bwino a matopewo ndi okwera, koma pomwepo mtengo wam'mangu ukuwonjezeka, matonthowo akuwonetsa kuti ndewu yopondereza. Hemc imatha kusintha izi moyenera, kotero kuti matope ali ndi mawonekedwe apamwamba pa kukhazikika kwa mtengo wochepa, ndikuonetsetsa kukhazikikako pomanga; Ali pamlingo wapamwamba wokwera, madzimadzi a matope amayenda bwino, kuchepetsa zovulala zamakina panthawi yomanga.

5. Sinthani kutseguka ndi kukhazikika kwa matope
Udindo wa hemo mu matope umawonetsedwanso pakulimbika kukhazikika ndi kubisala kwa matope. Hemc, ngati wotchinga, amatha kuwongolera mosamalitsa matope a matope ndikupewa stratization yake, kukhazikika ndi tsankho. Posintha kuchuluka kwa hemc kuwonjezeredwa, kukhazikika kwa matope ndi kukhazikika kumatheka malinga ndi zofunikira zosiyanasiyana zaukadaulo, makamaka pomanga kutentha kwakukulu ndi malo owuma, zotsatira za hemc ndizowonekeratu.

6. Ubwenzi wapakati pa kuchuluka kwa hemc ndi magwiridwe antchito
Kuchuluka kwa hemoc ndi imodzi mwazinthu zazikulu zomwe zimakhudza zamitundu yamitundu ya simenti. Nthawi zambiri, hemoc imawonjezeredwa, zoonekeratu zotsatira zake zotsatira za kusintha miyambo yachinyengo ili, koma palinso malire ena. Kuphatikiza mwambiri kwa hemc kumatha kuyambitsa matope ochulukirapo, omwe angakhudze mawonekedwe omanga. Chifukwa chake, mu ntchito zothandiza, ndikofunikira kusintha molondola kuchuluka kwa hemc malinga ndi kugwiritsa ntchito malo ndi zomanga za matope.

7. Mphamvu ya hemc pa matope a simenti atatha
Panthawi yolimba matope a simenti, gawo la hemmo lilipobe. Ngakhale hempc sitenga nawo mbali mwachindunji ndi simenti ya simenti, imatha kukhudza zinthu zakuthupi mutatha kuthana ndi madzi osungidwa ndi matope a simenti. Mwachitsanzo, hemo amatha kuchedwetsa ma simenti hydration, potero amalimbikitsa nyonga ndi kulimba kwa matope a simenti. Matope amathandizidwa ndi kuchuluka kwa hemc nthawi zambiri kumakhala ndi mphamvu yolimbana bwino komanso anti-odzipereka, komanso makamaka makamaka pantchito zomanga zomwe zimafunikira nthawi yogwira ntchito yomwe imafunikira nthawi yayitali.

Monga chowonjezera cha matope a simenti, hydroxyelyl methylcellulose (hemc) ndi gawo lofunikira pakuwongolera zinthu za nkhanza, kusungidwa kwamadzi, kukhazikika kwa matope. Hemo amatha kusintha madzimato, kusintha kwa matope a matope a simenti, kupewa matope ndi storimentar, ndikusintha matope. Komabe, kuchuluka kwa hemoc kumayenera kuwongolera kuti zitsimikizire kuti matope omwe amakwaniritsa zinthu zabwino kwambiri panthawi yogwira ntchito ndikupewa zovuta zomwe zimachitika chifukwa chowonjezera kwambiri. Chifukwa chake, pogwiritsa ntchito, kuchuluka kwa hemc kuwonjezeredwa kuyenera kusinthidwa malinga ndi zomangamanga zomangamanga zosiyanasiyana kuti athe kusewera mokwanira.
