Ma cellulose ether omwe amagwiritsidwa ntchito kwambiri ndi HEC, HPMC, CMC, PAC, MHEC ndi zina zotero. Non-ionic madzi sungunuka cellulose ether ali ndi adhesiveness, kubalalitsidwa bata ndi mphamvu posungira madzi, ndipo ndi ambiri ntchito zowonjezera zomangira. HPMC, MC kapena EHEC ntchito zambiri simenti ofotokoza kapena gypsum ofotokoza zomangamanga, monga zomangamanga matope, simenti matope, ❖ kuyanika simenti, gypsum, cementitious osakaniza, ndi yamkaka putty, etc., amene angathe kumapangitsanso dispersibility wa simenti kapena mchenga. ndi bwino kwambiri Adhesion, yomwe ndi yofunika kwambiri kwa pulasitala, matailosi simenti ndi putty. HEC imagwiritsidwa ntchito mu simenti, osati ngati cholepheretsa, komanso ngati chosungira madzi. HEHPC ilinso ndi izi.
Mankhwala a Hydroxypropyl methylcellulose HPMC amaphatikiza zinthu zambiri zakuthupi ndi zamankhwala kukhala zinthu zapadera zomwe zimagwiritsidwa ntchito ndi zinthu zosiyanasiyana:
Kusunga madzi: Imatha kusunga madzi pamalo otsekeka monga matabwa a simenti ndi njerwa.
Kupanga filimu: Itha kupanga filimu yowonekera, yolimba komanso yofewa yokhala ndi mphamvu yokana mafuta.
Organic solubility: Mankhwalawa amasungunuka mu zosungunulira za organic, monga kuchuluka koyenera kwa ethanol/madzi, propanol/madzi, dichloroethane ndi zosungunulira zopangidwa ndi zosungunulira ziwiri za organic.
Thermal gelation: Madzi amadzimadzi a chinthu akatenthedwa, gel osakaniza amapangidwa, ndipo gel opangidwawo amabwereranso kukhala yankho atakhazikika.
Zochita zapamtunda: Imapereka zochitika zapamtunda munjira yothetsera kuti mukwaniritse ma emulsification ofunikira ndi ma colloids oteteza, komanso kukhazikika kwa gawo.
Kuyimitsidwa: Hydroxypropyl methylcellulose imalepheretsa tinthu tating'ono kuti tisakhazikike, motero kulepheretsa mapangidwe a matope.
Chitetezo cha Colloids: Pewani madontho ndi tinthu ting'onoting'ono kuti tisagwirizane kapena kuti tifanane.
Madzi Osungunuka : Mankhwalawa amatha kusungunuka m'madzi mosiyanasiyana, ndende yochuluka imakhala yochepa kokha ndi mamasukidwe akayendedwe.
Non-ionic inertness: Chogulitsacho ndi ether yosakhala ya ionic cellulose yomwe sagwirizana ndi mchere wachitsulo kapena ma ion ena kuti apange mpweya wosasungunuka.
Kukhazikika kwa acid-base: koyenera kugwiritsidwa ntchito mumitundu ya PH3.0-11.0.
