Cov hmoov txhuv nplej siab ether feem ntau yog siv hauv kev sib xyaw ntawm cug, Maas thiab txiv qaub, thiab kev hloov pauv ntawm cug. Cov hmoov txhuv nplej siab feem ntau yog siv rau hauv kev sib txuas nrog cov neeg tsis tau hloov kho thiab hloov kho cellulos. Nws yog qhov haum rau ob qho nruab nrab thiab cov tshuab alkaline, thiab tau tshaj tawm nrog feem ntau cov ntxiv hauv gypsum thiab cov hmoov txhuv nplej siab thiab dej-soluble polymers xws li polyvinyl acetate).
Lub ntsiab muaj nuj nqi
(1) Cov peev xwm ua kom zoo sai: Nruab nrab viscosity, cov dej siab khaws cia;
(2) Qhov ntau npaum li cas yog me me, thiab ib qho qis dua yuav muaj cov nyhuv zoo;
(3) Txhim kho cov tshuaj tiv thaiv kev tiv thaiv kev tiv thaiv cov khoom ntawm nws tus kheej;
(4) Nws muaj lubric dej zoo, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv thiab ua rau kev ua haujlwm smoother.
Cov yam ntxwv tseem ceeb
Cov yam ntxwv ntawm cov hmoov txhuv nplej siab ether feem ntau yog dag hauv:
(a) txhim kho sag tiv taus;
(b) txhim kho kev tsim muaj peev xwm;
(c) Txhim kho cov dej khaws cov tshuaj cug.
Cov khoom noj qab zib
Starch ether feem ntau yog siv rau kev sib xyaw nrog methyl cellulose ether, uas qhia tau tias muaj kev sib tw zoo ntawm ob. Ntxiv ib qho nyiaj tsim nyog ntawm cov hmoov txhuv nplej siab ether rau methyl cellulose cellulose tuaj yeem txhim kho cov sag tiv thaiv thiab swb tsis kam ntawm lub cug. Cov txiaj ntsig ntau dua tus nqi.
Nyob rau hauv culture methyl cellulose cellulose ether, ntxiv tus nqi tsim nyog ntawm cov hmoov txhuv nplej siab thiab txhim kho cov tshuaj khib thiab txhim kho smoother thiab scoother.
Nyob rau hauv culture methyl cellulose cellulose ether, ntxiv tus nqi tsim nyog ntawm cov hmoov txhuv nplej siab ether tuaj yeem ua kom cov dej tawm ntawm lub tshuaj khib thiab ntev dua lub sijhawm qhib.
Starch ether yog qhov hloov kho cov hmoov txhuv nplej siab ether soluble, siv cov ntaub qhwv sab nrauv, cov khoom siv sab nrauv, cov ntaub ntawv sab hauv, cov neeg sawv cev sab hauv, masonry cug.
Starch ether yog haum rau txhua yam ntawm (MAAs, gypsum, based calcium putty, thiab ntau hom kev sib nraws kab cug.
Nws tuaj yeem raug siv ua ib admixture rau cov cement-based khoom, gypsum-based khoom thiab kua qaub-calcium cov khoom. Starch ether muaj kev sib haum zoo nrog lwm yam kev tsim kho thiab kev txhim kho; Nws yog qhov haum rau kev tsim kho kom qhuav xws li tshuaj cug, cov nplaum, plastering thiab dov cov ntaub ntawv. Starch ether thiab methyl cellulose ether (Tylosemc qib, muaj zog qauv, sag tsis kam thiab yooj yim ntawm kev tuav. Lub viscosity ntawm mortars, cov nplaum, cov yas thiab yob cov tshuaj tua neeg muaj zog los ntawm kev ntxiv ntawm cov hmoov txhuv nplej siab.
