HPMC yogwiritsidwa ntchito muWall Putty /Skim Coat

HPMC akhoza kugawidwa mu: kalasi yomanga, kalasi chakudya ndi mankhwala kalasi malinga ndi ntchito. Pakadali panoChina is kalasi yomanga kwambiri, m'kalasi yomanga,Wall putty/Skim Coat mlingo wachovala cha skim ufa ndi waukulu kwambiri. HPMC ufa ndi chiwerengero chachikulu cha zinthu zina zosakaniza powdery, mokwanira wothira blender, ndiye kuwonjezera madzi kupasuka, pa nthawi imeneyi HPMC akhoza kupasuka, koma osati agglomerate, chifukwa aliyense ngodya ting'onoting'ono, pang'ono HPMC ufa, madzi yomweyo kupasuka.Skim CoatMakampani opanga ufa ndi matope amagwiritsa ntchito njira iyi kwambiri. Hydroxypropyl methyl cellulose (HPMC) amagwiritsidwa ntchito ngati thickener ndi kusunga madzi mu putty mortar.

Kutentha kwa gel wa HPMC kumagwirizana ndi zomwe zili ndi methoxyl, kutsika kwa methoxylpansi, ndipamwamba kutentha kwa gel up. HPMC madzi ozizira yomweyo yankho mtundu ndi pambuyo glyoxal pamwamba mankhwala, kuika mu madzi ozizira mwamsanga omwazika, koma osati kusungunuka, mamasukidwe akayendedwe mmwamba, ndi kusungunuka. Thermosoluble Mtengo wa HPMC Mtunduwu sunapangidwe pamwamba ndi glyoxal. Kuchuluka kwa glyoxal ndi kwakukulu, kubalalitsidwa kumathamanga, koma mamasukidwe ake amachedwa, kuchuluka kwake ndi kochepa, m'malo mwake. HPMC akhoza kugawidwa mu nthawi yomweyo ndi kutentha sungunuka, mankhwala yomweyo, m'madzi ozizira mwamsanga omwazika, mbisoweka m'madzi, pa nthawi imeneyi madzi alibe mamasukidwe akayendedwe, chifukwa HPMC basi omwazika m'madzi, palibe kuvunda kwenikweni. Pafupifupi mphindi 2, kukhuthala kwamadzimadzi kumawonjezeka pang'onopang'ono, ndikupanga mawonekedwe a viscous colloid. Kutentha sungunuka mankhwala, mu madzi ozizira agglomeration, akhoza kukhala m'madzi otentha, mwamsanga omwazika, kutha m'madzi otentha, mpaka kutentha akutsikira kwa kutentha, mamasukidwe akayendedwe pang'onopang'ono kuoneka, mpaka mapangidwe mandala viscous colloid. Mtundu wosungunuka wa kutentha ungagwiritsidwe ntchito mkatiSkim Coat ndi matope, mu madzi guluu ndi ❖ kuyanika, akhoza kuwoneka chodabwitsa agglomeration, sungagwiritsidwe ntchito. Instant dissolve model, kuchuluka kwa ntchito ndikokulirapo pang'ono, mkatiSkim Coatufa ndi matope, ndi guluu wamadzimadzi ndi zokutira, zonse zitha kugwiritsidwa ntchito, zilibe vuto.

Njira yosungunulira ya HPMC imapangidwa ndi toluene, isopropyl mowa zosungunulira, ngati kutsuka sikwabwino kwambiri, padzakhala kukoma kotsalira. kugwiritsa ntchitoSkim Coat  ufa: chofunika ndi otsika, mamasukidwe akayendedwe 100000, ndikofunikira kuteteza madzi kuti akhale pafupi. Kugwiritsa ntchito matope: zofunikira zapamwamba, zofunikira za viscosity, 150000 kukhala bwino. Glue ntchito: kufunikira kwa zinthu pompopompo, kukhuthala kwakukulu. HPMC mu ntchito yeniyeni ya kuchuluka, ndi nyengo chilengedwe, kutentha, m'deralo imvi kashiamu khalidwe,Skim Coat formula ndi "zofuna zamakasitomala za khalidwe" zosiyana, ndipo pali kusiyana. Hydroxypropyl methyl cellulose (HPMC) ya viscosity -Skim Coatufa ndi100000, zina zazitali zomwe zimafunikira mumatope, zimafuna luso la 150,000 kugwiritsa ntchito. Komanso, ntchito yayikulu ya HPMC ndikusunga madzi, ndikutsatiridwa ndi makulidwe. MuSkim Coat, bola ngati kusungidwa kwa madzi kuli bwino, kukhuthala kumakhala kochepa (7-80000), ndizotheka, ndithudi, mamasukidwe akayendedwe ndi aakulu, kusungirako madzi wachibale kuli bwino, pamene mamasukidwe akayendedwe ndi oposa 100000, kukhuthala kwa kusungirako madzi sikokwanira; Zomwe zili mu Hydroxypropyl ndizokwera, kusunga madzi nthawi zambiri kumakhala bwinoko. Viscosity, kusungirako madzi, bwinoko, komanso kukhuthala, mumatope a simenti amagwiritsidwa ntchito bwino.

HPMC muSkim Coat, thickening, kusunga madzi ndi kumanga ntchito zitatu. Osatenga nawo mbali pazochita zilizonse. Chifukwa cha kuwira kungakhale madzi ochuluka, angakhalenso pansi si youma, pamwamba pa wosanjikiza kukala, komanso zosavuta kuwira. HPMC mu thickening zotsatira zaSkim Coat: mapadi akhoza unakhuthala kuti kuyimitsidwa, kotero kuti yankho kukhala yunifolomu mmwamba ndi pansi udindo odana otaya atapachikidwa. HPMC madzi posungira zotsatira muSkim Coat: kupangaSkim Coat youma pang`onopang`ono, wothandiza imvi kashiamu anachita pansi pa zochita za madzi. HPMC muSkim Coat ntchito yomanga: mafuta a cellulose, amatha kupangaSkim Coat ili ndi zomangamanga zabwino. HPMC sitenga nawo gawo pazosintha zilizonse zamakina, koma imangothandiza.

Wall putty/Skim Coat ufa ndi khalidwe lalikulu la phulusa la calcium lili ndi ubale waukulu, ndipo HPMC ilibe ubale waukulu. Kashiamu wochepa wa calcium yotuwira komanso kuchuluka kosayenera kwa CaO ndi Ca(OH)2 mu kashiamu wotuwira kumapangitsa kuti ufa ugwe. Ngati pali ubale pang'ono ndi HPMC, ndiye kuti HPMC kusasunga bwino madzi, kumayambitsanso ufa,Skim Coat ndi madzi, pa khoma, ndi zochita mankhwala, chifukwa cha m'badwo wa zinthu zatsopano, khoma laSkim Coat pansi pa khoma, pansi kukhala ufa, ndiyeno ntchito, osati mzere, chifukwa wapanga chinthu chatsopano (calcium carbonate). Zigawo zazikulu za ufa wa calcium imvi ndi: Ca(OH)2, CaO ndi kagawo kakang'ono ka CaCO3, CaO+H2O=Ca(OH)2 - Ca(OH)2+CO2=CaCO3↓+ H2O imvi kashiamu m'madzi ndi mpweya pansi zochita za CO2, mapangidwe kashiamu carbonate, ndi HPMC madzi okha, wothandiza imvi kashiamu bwino anachita, ake sanachite nawo chilichonse anachita.
