Wowuma ether makamaka ntchito zomangamanga matope, amene angakhudze kusasinthasintha matope zochokera gypsum, simenti ndi laimu, ndi kusintha kumanga ndi sag kukana matope.Ma ethers owuma nthawi zambiri amagwiritsidwa ntchito limodzi ndi ma cellulose ether omwe sanasinthidwe komanso osinthidwa.Ndizoyenera kuzinthu zonse zopanda ndale komanso zamchere, ndipo zimagwirizana ndi zowonjezera zambiri muzinthu za gypsum ndi simenti (monga ma surfactants, MC, starch ndi polyvinyl acetate ndi ma polima ena osungunuka m'madzi).
Zofunikira zazikulu:
(1) Wowuma ether nthawi zambiri amagwiritsidwa ntchito limodzi ndi methyl cellulose ether, zomwe zikuwonetsa kuyanjana kwabwino pakati pa awiriwa.Kuonjezera mlingo woyenerera wa starch ether ku methyl cellulose ether kungathandize kwambiri kuti sag resistance ndi kutsetsereka kwa matope, ndi zokolola zambiri.
(2) Kuonjezera mlingo woyenerera wa starch ether ku matope omwe ali ndi methyl cellulose ether akhoza kuonjezera kusasinthasintha kwa matope ndikusintha madzimadzi, kupangitsa kuti zomangamanga zikhale zosavuta komanso zopalasa bwino.
(3) Kuonjezera mlingo woyenerera wa starch ether ku matope omwe ali ndi methyl cellulose ether kungapangitse kusungirako madzi mumatope ndikutalikitsa nthawi yotseguka.
(4) Wowuma etha ndi mankhwala osinthidwa wowuma etha sungunuka m'madzi, n'zogwirizana ndi zina zowonjezera mu matope youma ufa, ntchito kwambiri zomatira matailosi, kukonza matope, pulasitala pulasitala, mkati ndi kunja khoma putty, gypsum-based ophatikizidwa Mgwirizano ndi kudzaza zipangizo. , mawonekedwe othandizira, matope omanga.
Makhalidwe a wowuma ether makamaka amakhala mu: (a) kukulitsa kukana kwa sag;(b) kuwongolera magwiridwe antchito;(c) kuwongolera kuchuluka kwa kusunga madzi mumatope.
Kagwiritsidwe:
Wowuma ether ndi oyenera mitundu yonse ya (simenti, gypsum, laimu-kashiamu) mkati ndi kunja khoma putty, ndi mitundu yonse ya kuyang'ana matope ndi pulasitala matope.
Itha kugwiritsidwa ntchito ngati chophatikizira pazinthu zopangira simenti, zopangidwa ndi gypsum ndi zinthu za lime-calcium.Wowuma ether amagwirizana bwino ndi zomangamanga ndi zosakaniza zina;ndizoyenera kwambiri pomanga zosakaniza zowuma monga matope, zomatira, pulasitala ndi zida zopukutira.Ma starch ethers ndi methyl cellulose ethers (Tylose MC grade) amagwiritsidwa ntchito limodzi pomanga zosakaniza zowuma kuti apereke kukhuthala kwakukulu, kapangidwe kolimba, kukana kwa sag komanso kugwirika kosavuta.Kukhuthala kwa matope, zomatira, pulasitala ndi ma rolls okhala ndi ma ether apamwamba a methyl cellulose amatha kuchepetsedwa powonjezera ma starch ethers.
