Sida loo doorto hydroxypropyl methylcelrellase madaafiic lagu ridayaa?

Qiimaha General PH ee Alaabta GYPSUM waa aashito ama dhexdhexaad. Hadda waxaa jira laba nooc oo fasalka dhismaha ahhydroxypropyl methylrcelluloseSuuqa: Kala-saaridda unugyada unugyada unugyada ah iyo qolka yar ee maskaxda. Cilmi-socodka degdega ah ee degdegga ah kuma haboona nidaamyada gypsum. Alaabada, xaruuftu waxay aad ugu liitaa xaalado aashitada ah ama dhexdhexaad ah, iyo in si tartiib tartiib ah loo kala qaybiyo hydroxypropylylkyllcelrelolose waxaa lagu kala diri karaa wax faafinta, laakiin waa sahlan tahay in hoobiyeynta loo yaqaan 'your'. Darbiga muddo gaaban, dhibco yar yar oo granralar ah ayaa u muuqda inay dusha sare ka soo baxaan). Waqtigan xaadirka ah, alaabada gypsum, gaar ahaan madaafiicda lagu buufiyo, waxaa loo baahan yahay in ether cypsum si buuxda loo kala firdhi karo loona kala diri karo waqti aad u yar, kaas oo naga dooda inaan si qoto dheer u sameyno cilmi-baarista qoto-dheer ee chet-ka habka wax soo saarka. DIIWAANKA DARYEELKA (MAYA waxa loogu yeero iskugeynta waxyaabaha kale ee lagu daro ee kadhadashada fasalka caadiga ah ee chelka caadiga ah), si ay ula qabsadaan nidaamka hoolka-hoolka ee gypsum. Hydroxypropyl methylulose ether oo leh daaweyn qoto dheer ayaa lahaan kara waqti deggan oo xasilloon iyo mowduuc farsamo oo wanaagsan, waxayna si weyn u hagaajin kartaa heerka iyo habka dhameystirka hoobitaanka.

Machine-sprayed gypsum mortar generally uses relatively low-viscosity hydroxypropyl methylcellulose ether between 20,000 and 75,000, and the addition amount is generally 0.2% to 0.4%. Waqtiga dejinta ee mashiinka mashiinka lagu buufiyay ayaa la xakameeyaa qiyaastii 1 saac. Waxaan u isticmaalnaa hoobiyeynta gypsum, viscosity caag ah, thathotropy, rheology iyo is-xakameyn ah si aan u xukumo waxqabadka madaafiicda loo yaqaan 'gysum'.

Waxaan u tixgelinaynaa kontaroolka tayada ee ah ee ah hannaanka qaddarka ee burburka, isku-darka (sibidhka, waxaa loo isticmaali karaa budada kaalshiyamka culus, budada kacaanka (poludroxypropyl ether, oo la ballaariyey perlite, dib-u-dhacyada. Qaaciddada wax soo saarka ee waxtarka leh.

Hydroxypropyl byluyl celther etherMadaafiicda gypsum wuxuu leeyahay daahir sare iyo shaqooyin wanaagsan, waxaana si weyn loogu ammaanay madaafiicda gypsum-ka.
