Etha wothira mu matope

Etha wothira sitachi Limbitsani matope, onjezerani kukana kwa kusamuka, kukana kwa kusamuka ndi rheology ya matopewo

Mwachitsanzo, popanga guluu wa matailosi, putty, ndi plastering mortar, makamaka tsopano popeza kupopera kwa makina kumafuna kusinthasintha kwakukulu, mwachitsanzo, ndikofunikira kwambiri mu plaster yopangidwa ndi gypsum (plaster yopopera makina imafuna kusinthasintha kwakukulu koma ingayambitse kutsika kwakukulu, starch Ether ikhoza kubwezeretsa cholakwikachi).

Kukana kwa madzi ndi kutsika kwa madzi nthawi zambiri kumakhala kotsutsana, ndipo kuwonjezeka kwa kutsika kwa madzi kudzachepetsa kukana kwa madzi. Chomangira chokhala ndi mphamvu za rheological chingathetse bwino kutsutsana kuti mphamvu yakunja ikagwiritsidwa ntchito, kukhuthala kwa madzi kumachepa, zomwe zimapangitsa kuti mphamvu yakunja igwire ntchito bwino komanso kuti ipope mosavuta, ndipo mphamvu yakunja ikachotsedwa, kukhuthala kwa madzi kumawonjezeka ndikuwonjezera kukana kwa madzi.

Pakuwonjezeka kwa malo a matailosi pakali pano, kuwonjezera starch ether kungathandize kuti guluu wa matailosi usagwedezeke.

2) Kuonjezera nthawi yotsegulira

Pa zomatira za matailosi, zimatha kukwaniritsa zofunikira za zomatira zapadera za matailosi zokhala ndi nthawi yayitali yotseguka (Kalasi E, imakula kuyambira mphindi 20 mpaka mphindi 30 mpaka kufika pa 0.5MPa).

a. Kukonza magwiridwe antchito pamwamba

Starch ether ingapangitse pamwamba pa matope opangidwa ndi gypsum ndi simenti kukhala osalala, osavuta kugwiritsa ntchito, komanso imakhala ndi zokongoletsa zabwino. Ndi yofunika kwambiri pa matope opangidwa ndi plaster ndi matope okongoletsa okhala ndi zigawo zoonda monga putty.

b. Kagwiridwe ka ntchito ka starch ether

Pamene starch ether isungunuka m'madzi, imafalikira mofanana mu simenti ya simenti. Chifukwa mamolekyu a starch ether ali ndi kapangidwe ka netiweki ndipo ali ndi mphamvu yoipa, amayamwa tinthu ta simenti tomwe tili ndi mphamvu yoipa, zomwe zingagwiritsidwe ntchito ngati mlatho wosinthira kuti zilumikize simenti, motero zimapatsa phindu lalikulu la slurry lomwe lingapangitse kuti pakhale mphamvu yoletsa kutsetsereka kapena kutsika.
