Kodi Starch Ether ndi chiyani?

Wowuma etheramagwiritsidwa ntchito makamaka pomanga matope, omwe angakhudze kusasinthika kwa matope opangidwa ndi gypsum, simenti ndi laimu, ndikusintha kumanga ndi kukana kwamatope.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 ma polima osungunuka m'madzi monga polyvinyl acetate).

Ntchito yaikulu

(1) Good mofulumira thickening luso: sing'anga mamasukidwe akayendedwe, mkulu madzi posungira;

(2) Mlingo ndi wochepa, ndipo mlingo wochepa ukhoza kukhala ndi zotsatira zabwino;

(3) Kupititsa patsogolo luso la anti-sag la zinthu zomwezo;

(4) Ili ndi lubricity yabwino, yomwe imatha kusintha magwiridwe antchito azinthu ndikupangitsa kuti ntchitoyo ikhale yabwino.

Mndi mawonekedwe

Makhalidwe a starch ether amakhala motere:

(a) Kupititsa patsogolo kukana kwa sag;

(b) Kupititsa patsogolo luso lomanga;

(c) Kuwongolera kuchuluka kwa kusunga madzi mumatope.

Synergy

Wowuma ether nthawi zambiri amagwiritsidwa ntchito limodzi ndi methyl cellulose ether, zomwe zimawonetsa kuyanjana kwabwino pakati pa ziwirizi.Kuonjezera kuchuluka koyenera kwa wowuma ether ku methyl cellulose ether kumatha kusintha kwambiri kukana kwa sag komanso kukana kwamatope.Zokolola zapamwamba.

Mu matope omwe ali ndi methyl cellulose ether, kuwonjezera kuchuluka koyenera kwa wowuma ether kumatha kukulitsa kugwirizana kwa matope ndikusintha madzimadzi, kupangitsa kuti nyumbayo ikhale yosalala komanso kukanda bwino.

Mu matope omwe ali ndi methyl cellulose ether, kuwonjezera kuchuluka koyenera kwa wowuma ether kumatha kuwonjezera kusungidwa kwamadzi mumatope ndikutalikitsa nthawi yotseguka.

Starch ether ndi wowuma wosinthidwa ndi mankhwala osungunuka m'madzi, ogwirizana ndi zina zowonjezera mumatope owuma, omwe amagwiritsidwa ntchito kwambiri pomatira matailosi, matope okonza, pulasitala, mkati ndi kunja kwa khoma putty, gypsum-based caulking and filling Equipment, othandizira mawonekedwe, matope a miyala.

Wowuma ether ndi oyenera mitundu yonse ya (simenti, gypsum, laimu kashiamu ofotokoza) mkati ndi kunja khoma putty, ndi mitundu yosiyanasiyana ya akukumana matope 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;ndi oyenera kumanga zowuma zowuma monga matope, zomatira, pulasitala ndi zida zokutira.Wowuma ether ndi methyl cellulose ether (KimaCellMC grade) amagwiritsidwa ntchito limodzi pomanga zosakaniza zowuma kuti apereke kukhuthala kwamphamvu, mawonekedwe amphamvu, kukana kwa sag komanso kuwongolera kosavuta.Kukhuthala kwa matope, zomatira, pulasitala ndi ma rolls okhala ndi ma ether apamwamba a methyl cellulose amatha kuchepetsedwa powonjezera ma starch ethers.
