Tsiku lililonse Q & A pa gypsum ntchito zamankhwala

Kodi lingaliro lokhazikika la ether ndi liti?
Yankho: Mafuta owoneka bwino amagwiritsidwa ntchito pomanga matope, omwe angakhudze kuchuluka kwa matope, simenti ndi laimu, ndikusintha kapangidwe ka matope ndi kukana kwa matope. Kukhuta manja nthawi zambiri kumagwiritsidwa ntchito molumikizana ndi celluselose yosinthika komanso yosinthidwa. Ndioyenera kwa onse osalowerera ndale komanso alkaline, ndipo amagwirizana ndi zowonjezera zambiri mu gypsum ndi zowonjezera, MC, wowuma ndi ma polymer ena osungunuka.

Makhalidwe a wowuma ether amagona mu:
(1) Sinthani kukana kwa Aleg;
(2) Kupititsa patsogolo kugwirizana;
(3) zokolola zapamwamba.

Kodi ntchito yayikulu yowuma ndi matope a gypsum?
Yankho: Ether ether ndi imodzi mwazowonjezera zazikulu za matope a ufa. Itha kukhala yogwirizana ndi zina zowonjezera. Amagwiritsidwa ntchito kwambiri m'masamba a Tile, kukonza matope, kupatuka gypsum, omwe ndi oyang'anira grace, oyimira matope, oyenera kutulutsa matope kapena matope a Sypsum. Imagwira ntchito motere:

(1) Nthawi zambiri ether nthawi zambiri imagwiritsidwa ntchito limodzi ndi methyl cellulose ether ether, yomwe imawonetsa zotsatira zabwino pakati pa awiriwo. Kuwonjezera kuchuluka kwa ether ether to methyl cellulose ether ether ether amatha kusintha matope ndi kukana matope, ndi mtengo wambiri wotalika.

Kodi ndi zabwino zamagetsi ndi njira zosungira za ether ether?
Yankho: Itha kugwiritsidwa ntchito ngati chogwiritsira ntchito mankhwala a simenti, mankhwala a gypsum ndi aspium.

(1) Ubwino ndi Mapulogalamu:

a. Zimakhudza kukula kwa matope, zimatha kumangika mwachangu, ndikukhala ndi mkaka wabwino;
b. Mlingowu ndi wocheperako, ndipo kuchuluka kochepa kwambiri kumatha kukhala kovuta;
c. Sinthani luso lotsutsa matope;
d. kuwonjezera nthawi yotseguka;
e. Sinthani magwiridwe antchito a zinthuzo ndikupangitsa opareshoni.

(2) Kusungira:

Chogulitsacho chimatha kukhala chinyezi ndipo chimayenera kusungidwa pamalo owuma komanso abwino mu ma CD. Ndikofunika kugwiritsa ntchito mkati mwa miyezi 12. (It is recommended to be used in conjunction with high-viscosity cellulose ether, and the general ratio of cellulose ether to starch ether is 7:3~8:2)

Kodi gawo la methyl cellulose ether pamatope a ufa wa ufa ndi chiyani?
Yankho: Methyl hydrothyl cellulose ether (mhec) ndi methyl hydroxpyl cellulose ether ethelose ether.

Mu gawo la matope a ufa, methyl cellulose ether ether ndi chinthu chofunikira chosinthika cha matope a ufa wowuma monga matope a glasive, matope a matope, utsi wa matope komanso nkhani zokopa. M'malo osiyanasiyana owuma a ufa, methyl cellulose ether amagwiritsa ntchito gawo la kusungidwa kwamadzi ndikukula.

Kodi kupanga methylcellulose ndi chiyani?
Yankho: Choyamba, cellulose zimaphwanyidwa, kenako imanyengedwa komanso yokometsedwa ndi koloko ya caustic. Onjezani Olefin oxide (monga ethylene oxide kapena propylen oxide) ndi methyl chloride kuti mukwaniritse. Pomaliza, kutsuka madzi ndi chiyeretso kumachitika kuti zitheke kukhala ufa woyera. Ufa uwu, makamaka yankho lake la matenda, lili ndi zinthu zosangalatsa. Cellulose ether yomwe imagwiritsidwa ntchito mu makampani omanga ndi methyl hydrothyl cellulose ethel ethelose ethelose ether kapena methyl hydrobropyl hydroxpyl. Izi zimachita gawo lofunikira kwambiri m'munda wamatontho owuma ufa. Udindo Wofunika.
