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. Products, the solubility is very poor under acidic or neutral conditions, and slow-dissolving hydroxypropyl methylcellulose can be dissolved in gypsum products, but slow-dissolving cellulose has a significant disadvantage, it is easy to agglomerate (when gypsum After the mortar is stirred on the wall for a short time, small granular spots tend to appear on the surface). Waqtigan xaadirka ah, alaabada gypsum, gaar ahaan hoobiyeynta lagu buufiyo, waxaa loo baahan yahay in ether cypsum si buuxda loo kala firdhiyo loona kala diri karo muddo aad u yar, kaas oo naga dooda inaan si qoto dheer u sameysanno geedi socodka dib-u-soo-dejinta unugyada. 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 hannaanka qaddarka ee nasashada ee nasashada, isku-darka (sibidhka, waxaa loo isticmaali karaa budada kaalshiyamka ee methyl-ka, oo la ballaariyo perlite, dib-u-dhigista perlite, respard reslars-ka) doorashada qaaciddada abuurka.
Hydroxypropyl byluyl celther etherMadaafiicda gypsum wuxuu leeyahay daahir sare iyo shaqooyin wanaagsan, waxaana si weyn loogu ammaanay madaafiicda gypsum-ka.
