hpmc rdp yogwiritsidwa ntchito mu Cement Render & Plaster EIFS & ETICS
JINJI® HPMC ili ndi zinthu zosiyanasiyana zomwe zimapangitsa kuti ikhale yogwira mtima komanso yokondedwa pa EIFS&ETICS.
Thermal insulation board system, yomwe nthawi zambiri imaphatikizapo ETICS (EIFS) (External Thermal Insulation Composite System / Exterior Insulation Finish System), kuti mupulumutse mtengo wamagetsi otentha kapena ozizira, matope abwino omangirira ayenera kukhala: osavuta kusakaniza, osavuta kugwiritsa ntchito. , mpeni wopanda ndodo; Zabwino zoletsa kupachika zotsatira; Kumamatira kwabwino koyambirira ndi mawonekedwe ena. Dongo la pulasitala liyenera kukhala: losavuta kugwedezeka, losavuta kufalitsa, mpeni wosagwira, nthawi yayitali yachitukuko, luso lonyowa pansalu yaukonde, losavuta kuphimba ndi zina. Zomwe zili pamwambazi zitha kukwaniritsidwa powonjezera zinthu zoyenera za cellulose ether monga Hydroxypropyl Methyl Cellulose (HPMC) kumatope.
Zogulitsa zathu za cellulose za HPMC ndi mankhwala a RDP zimapereka zosintha zotsatirazi ku EIFS:
• Kupititsa patsogolo mphamvu zomatira ndi kusinthasintha: mapadi amakhala ndi ntchito yabwino yowonjezereka ndi mafuta, zomwe zingathe kupititsa patsogolo mphamvu zomatira ndi kusinthasintha kwa zomatira za EIFS.
• Kusungika kwa madzi ndi nthawi yotalikirapo yogwira ntchito: kumachepetsa kutayika kwa madzi mu magawo omwe amayamwa mumipangidwe. Kutha kusunga madzi kwa cellulose kumapangitsanso kwambiri mphamvu yomatira ya zomatira za EIFS. Izi ndichifukwa choti zomangira zimakhala ndi nthawi yokwanira ya hydration ndipo nthawi yomweyo samataya madzi.
• Kusasinthika kwazinthu ndi rheology: mapadi ndizofunikira kwambiri kuti zisinthe kusasinthika koyenera mumatope atsopano. Kusasinthasintha koyenera kumathandizira pulasitala watsopano kumamatira bwino pamakoma komanso kupangitsa kuti malo azikhala osalala komanso ogwiritsidwa ntchito mosavuta popanda kumamatira. Njira yamadzimadzi ya MelaColl ndi njira yosakhala ya Newtonian, ndipo katundu wake amatchedwa thixotropy.
• Kupititsa patsogolo kwa hydrophobicity: Pambuyo powonjezera cellulose, hydrophobicity ya EIFS yasintha, mphamvu yoletsa madzi imawonjezeka kwambiri.
• Kupititsa patsogolo ntchito: Kuwongolera bwino ndi kuchepetsa kukhazikika kwa cellulose kungagwiritsidwe ntchito mosavuta ku zomatira za EIFS, zosavuta kugwira ntchito ndi zomangamanga, ndipo zingathe kupititsa patsogolo ntchito yomanga.
• Limbikitsani ntchito zokutira ndi mphamvu zoyambilira: mapadi amaphatikiza kuphatikiza kwa zinthu za polima komanso kulimba kwa zinthu zopanda organic. Amatha kutsimikizira mphamvu yoyambirira ya matope ndi zinthu zina zofunika ku EIFS ndi zomangamanga zatsopano.
• Kusamva bwino kwa madzi, kuyanjana kwabwino ndi zinthu zonse: mapadi amachepetsa kutayika kwa madzi mu magawo omwe amayamwa mumipangidwe. Kutha kusunga madzi kwa cellulose kumapangitsanso kwambiri mphamvu yomatira ya zomatira za EIFS. Izi ndichifukwa choti zomangira zimakhala ndi nthawi yokwanira ya hydration ndipo nthawi yomweyo samataya madzi.
• Onetsani mphamvu zambiri, zomatira zolimba, ndi kukana kwa alkali: mapadi ali ndi kusunga bwino, katundu wochuluka, katundu wokhazikika wa mankhwala amatsutsa bwino kuukira kwa alkali.
