Ii-cellulose ethers ezisetyenziswa rhoqo ziquka i-HEC, i-HPMC, i-CMC, i-PAC, i-MHEC nezinye ezifana nazo. I-non-ionic water-soluble cellulose ether ine-adhesiveness, i-dispersion stability kunye ne-water-retaining capacity, kwaye sisixhobo esisetyenziswa rhoqo kwizixhobo zokwakha. I-HPMC, i-MC okanye i-EHEC zisetyenziswa kakhulu kwizakhiwo ezisekwe kwisamente okanye kwi-gypsum, ezifana ne-masonry mortar, i-cement mortar, i-cement coating, i-gypsum, i-cementitious mixture, kunye ne-milky putty, njl.njl., ezinokuphucula ukusasazeka kwesamente okanye isanti kwaye ziphucule kakhulu i-Adhesion, ebaluleke kakhulu kwi-plaster, i-tile cement kunye ne-putty. I-HEC isetyenziswa kwisamente, kungekuphela nje njenge-retarder, kodwa nakwi-arhente yokugcina amanzi. I-HEHPC nayo inalo olu setyenziso.
Iimveliso zeHydroxypropyl methylcellulose HPMC zidibanisa iipropati ezininzi zomzimba nezekhemikhali zibe ziimveliso ezikhethekileyo ezineendlela ezahlukeneyo zokusetyenziswa kunye neepropati:
Ukugcinwa kwamanzi: Ingagcina amanzi kwiindawo ezinemingxuma efana neebhodi zesamente eludongeni kunye nezitena.
Ukwenziwa kwefilimu: Ingenza ifilimu ecacileyo, eqinileyo nethambileyo enokumelana kakuhle negrisi.
Ukunyibilika kwezinto eziphilayo: Le mveliso iyanyibilika kwezinye izinto eziphilayo, ezifana nomlinganiselo ofanelekileyo we-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane kunye nenkqubo yokunyibilikisa eyenziwe zizinto ezimbini eziphilayo.
I-gelation yobushushu: Xa isisombululo samanzi semveliso sishushu, kuya kuvela ijeli, kwaye ijeli eyenziweyo iya kubuyela kwisisombululo xa ipholile.
Umsebenzi womphezulu: Ubonelela ngomsebenzi womphezulu kwisisombululo ukuze kufezekiswe i-emulsification efunekayo kunye ne-colloids ezikhuselayo, kunye nokuzinzisa isigaba.
Ukumiswa: I-Hydroxypropyl methylcellulose ithintela amasuntswana aqinileyo ukuba angahlali, ngaloo ndlela ithintela ukwakheka kwesamente.
IiColloids eziKhuselayo: Zithintela amathontsi kunye namasuntswana ukuba angadibani okanye ajijeke.
Amanzi Anyibilikayo: Imveliso inokunyibilikiswa emanzini ngobuninzi obahlukeneyo, uxinaniso oluphezulu lunqunyelwe kuphela yi-viscosity.
Ukungangeni kwe-ionic: Le mveliso yi-non-ionic cellulose ether engadibaniyo neetyuwa zesinyithi okanye ezinye ii-ion ukuze zenze iiprecipitates ezinganyibilikiyo.
Uzinzo lwe-asidi-base: ifanelekile ukusetyenziswa kuluhlu lwe-PH3.0-11.0.
