Mankhwalaakugwiritsidwa ntchito kwambiri pazolinga za simenti, makamaka m'matavala owuma, chifukwa cha madzi awo abwinobwino komanso kukula kwake. Chifukwa chake, katundu ndi mawonekedwe acellulose ether Zowonjezera za simenti zosinthidwa ndi kulumikizana pakaticellulose ether Ndipo simenti pang'ono tsopano yayamba kuyang'ana kwambiri m'minda yomanga ndi ukadaulo m'zaka zaposachedwa. Zotsatira zambiri zofufuzira zatheka. Kuphatikiza kafukufuku akupita kwathu ndi kunja, alipo zovuta zotsatirazi pakufufuza ndi kugwiritsa ntchitocellulose ether Zinthu Zosinthidwa za Simenti:
1.Pali ndi mitundu yambiri yamankhwala.Ngakhalemankhwala Zogwiritsidwa ntchito mu simenti-zochokera kumenti zimagawidwa m'mitundu yambiri monga hec, hemc ndi hpmc chifukwa cha kuchuluka kwawo. Mtundu womwewo wamankhwalaKhalani ndi kusiyana kosiyanasiyana pamapangidwe azosamwa, kulemera kwa maselo, kuchuluka kwa zolowa m'malo. Pakadali pano, kafukufuku kwambiri kunyumba ndi kunja kumangoyang'ana imodzi kapena zingapomankhwala.Kusankha kwacellulose ether amangokhala ndi magawo awo a ntchito. Mawonekedwe opangidwa ndimankhwala sanawonedwe, ndipo oyimira kwawo sakhala oimira. Mapeto ake ndi chifukwa chosapeweka chifukwa cha "cholowa m'malo", ndipo palinso palimodzi ndi mikangano pakati pa zotsatira zoyeserera. Chifukwa chake, ndikofunikira kuphunzira mwadongosolo gulu ndi zinthu zamakhalidwe ndi mitundu yosiyanasiyana yacellulose ether zojambula zophatikizika.
Mabuku ophunzitsira aphunzirapomankhwala Pazinthu zosiyanasiyana za zinthu zopangidwa, ndikuchita kusanthula kwina kwa magwiridwe ake, koma alephera kudziwa ubale pakati pa ma molecularmankhwala ndi katundu wa simenti yosinthidwa. Nthawi zonse, ndipo pali zosiyana zodziwikiratu pamachitidwe awo. Pamodzicellulose etherZovala za simenti zochokera, pali maphunziro ochepa pazovala zokhala ndi zojambula zosiyanasiyana, zomwe sizingafotokoze momwe mapangidwe osiyanasiyana amapangiracellulose ether- Zovala za simenti. . Ngakhale mabuku ena amapezeka kutimankhwala Ndi zida zophatikizira zosiyanasiyana zimakhala ndi zovuta zosiyanasiyana pamzanga, zifukwa zoyambilira sizinaponderezenso.
3. Njira ya Mphamvu yacellulose ether Pa simenti hydration kinetics amaphunziridwanso. Pakadali pano, ponena za kuchedwa kwamankhwala a hydrate wacellulose ether, ngakhale ADSORASTION imawonedwa kuti ndi chifukwa chenicheni chochedwa hydration wacellulose ether, zimapezeka kuti mphamvu zolimbacellulose ether, kuchedwa kwamapulogalamu ambiri. Makina a ADSORASS pakatimankhwala ndi zinthu za simenti hydrate, komanso zifukwa zomwe adsorraps osiyanasiyana adsorration osiyanasiyanamankhwala ndi mankhwala opha ma simenti, sanaphunzirenso.
Mabuku ogulitsa 4.mankhwala imatha kukhudza kwambiri kapangidwe kazinthu za simenti.Mankhwala Amakhulupiriranso kuti ali patali ndipo amakhala ndi mphamvu yodzimangirira mpweya wabwino, potero amawonjezera chidwi cha ma slor a simenti olimba. Komabe, mphamvu yamankhwala Panthawi yokhazikika ndi kapangidwe kake kwa kagawi kamenti wa simenti sikukambirana kawirikawiri.
5. Zachilengedwe ndizofunikira pakugwiritsa ntchitomankhwala muzinthu zamimenti. Tsoka ilo, pali maphunziro ochepa pazambiri zacellulose ether simenti yosinthidwa kunyumba ndi kunja.
