MHEC LH 620M

A na-eji EipponCell MHEC LH 620M methyl hydroxyethyl cellulose mee ihe na gypsum slurry iji nye mmetụta nhịahụ pụtara ìhè.N'ime ụlọ okpomọkụ, ka viscosity na usoro onunu ogwu nke cellulose ether na-abawanye, mmetụta ya na-esiwanye ike na-apụtawanye ìhè.Otú ọ dị, ka okpomọkụ na-ebili, viscosity nke cellulose ether na-ebelata, na-eme ka ọ daa mbà n'obi nke mmetụta ya.Nke a na-eduga n'ịbelata nrụgide nke mkpụrụ osisi, viscosity plastik, na pseudoplasticity nke ngwakọta gypsum, n'ikpeazụ na-ebute ọrụ adịghị mma.

Cellulose ether na-akwalite njigide mmiri nke gypsum.Otú ọ dị, ka okpomọkụ na-abawanye, njide mmiri nke gypsum gbanwetụrụ na-ebelata nke ukwuu na ọbụna na-efunahụ mmetụta mmezi njide mmiri ya na 60 Celsius.A na-eme ka ọnụ ọgụgụ njide mmiri nke gypsum slurry dịkwuo mma site na cellulose ether, na ọnụ ọgụgụ njide mmiri ji nwayọọ nwayọọ rute ebe saturation na mmụba nke ọdịnaya maka HPMC gbanwetụrụ gypsum slurry nwere viscosities dị iche iche.N'ozuzu, njide mmiri nke gypsum dị nhata na viscosity nke cellulose ether, ma ọ na-enwe mmetụta dị nta na elu viscosity.

Mgbanwe na njide mmiri nke cellulose ethers na okpomọkụ nwere njikọ chiri anya na microscopic morphology nke cellulose ethers na mmiri mmiri mmiri.N'ebe ụfọdụ, cellulose ether na-agbakọta ma na-etolite nnukwu njikọ colloidal, na-egbochi ụzọ nnyefe mmiri nke ngwakọta gypsum nke ọma iji nweta njigide mmiri dị mma.Otú ọ dị, dị ka okpomọkụ na-ebili, ihe ndị na-ekpo ọkụ na-ekpo ọkụ nke cellulose ether na-eme ka ndị òtù colloidal buru ibu nke e hiwere na mbụ gbasaa, na-ebute mbelata nke njide mmiri.
