Kodi ndi zinthu ziti zomwe zimagwiritsidwa ntchito mu ufa wa emulsion wosungunukanso?
Ufa wa Redispersible Emulsion (RDP) ndi chisakanizo chovuta cha zigawo zingapo, chilichonse chimathandizira magwiridwe antchito ake. Ngakhale kuti mapangidwe amatha kusiyana kutengera wopanga ndi momwe akufunira kugwiritsa ntchito, zigawo za RDP zomwe zimagwiritsidwa ntchito nthawi zambiri ndi izi:
1.Chomangirira cha Polima: Gawo lalikulu la RDP ndi chomangira cha polima, chomwe nthawi zambiri chimachokera ku vinyl acetate ethylene (VAE), vinyl acetate versatate (VeoVA), ethylene vinyl chloride (EVC), kapena ma copolymer ena. Chomangira cha polima ichi chimapereka mphamvu zomatira ndipo chimapanga filimu yogwirizana ikauma.
2.Colloid Yoteteza: Kuti tinthu ta polymer tisamaundane komanso kuti tinthu ta polymer tisamaundane, timawonjezera colloid yoteteza. Ma colloid oteteza omwe amagwiritsidwa ntchito nthawi zambiri amakhala ndi ma cellulose ethers (monga hydroxyethyl cellulose, methyl cellulose), polyvinyl alcohol (PVA), ndi zinthu zotengedwa ngati starch.
3.Zopangira pulasitiki: Mapulasitiki amaphatikizidwa kuti akonze kusinthasintha ndi kugwira ntchito kwa filimu ya RDP. Amathandiza kuchepetsa kusweka ndikuwongolera kumamatira, makamaka m'mapangidwe omwe amasunthidwa kapena kusinthika.
4.Zodzaza: Zodzaza zopanda organic monga calcium carbonate, talc, silika, kapena dongo zitha kuwonjezeredwa ku RDP formulations kuti ziwongolere kuchuluka kwa zinthu, kuchepetsa mtengo, komanso kusintha mawonekedwe a makina. Zodzaza zimathandizanso kuwongolera rheology ndikuwongolera mawonekedwe a zophimba ndi ma mortars.
5.Zoletsa kuipitsidwa kwa mpweya: Mankhwala ochotsera thovu amaphatikizidwa kuti achepetse kupangika kwa thovu panthawi yopanga ndi kugwiritsa ntchito RDP. Thovu lochulukirapo likhoza kusokoneza magwiridwe antchito ndi mawonekedwe a zokutira ndi zomatira.
6.Zokhazikika: Zokhazikika zimagwiritsidwa ntchito kusunga kukhazikika kwa emulsion ndikuletsa kulekana kwa gawo kapena kuphatikizika kwa tinthu ta polima. Zimathandiza kuonetsetsa kuti zinthu za RDP zikugwira ntchito bwino komanso kukhazikika kwa kusungirako.
7.Othandizira Kubalalitsa: Zinthu zotulutsira madzi zimathandiza kufalitsa tinthu ta RDP m'madzi, kulimbikitsa kufalikira kofanana komanso kupewa kusonkhana kwa ufa. Zimathandizira kuti ufa wa RDP usungunukenso m'madzi, zomwe zimathandiza kuti ulowe m'madzi.
8.Zinthu Zoletsa Kuzizira: Mu nyengo yozizira kapena nthawi yosungiramo kutentha kochepa, mankhwala oletsa kuzizira angawonjezedwe kuti asaundane ndikusunga kukhazikika kwa ma RDP emulsions.
9.Mankhwala Ophera Tizilombo Toyambitsa Matenda: Mankhwala ophera tizilombo toyambitsa matenda angaphatikizidwe kuti aletse kukula kwa tizilombo toyambitsa matenda ndikuwonjezera nthawi yogwiritsira ntchito mankhwala a RDP, makamaka m'mankhwala omwe angathe kuipitsidwa.
10.Zowonjezera Zina: Kutengera ndi zofunikira zenizeni za ntchito yomwe mukufuna kugwiritsa ntchito, zowonjezera zina monga zothina, zosakaniza, zolumikizirana, ndi zothandizira kupanga filimu zitha kuphatikizidwa mu RDP formulations kuti zigwirizane ndi mawonekedwe awo ndi magwiridwe antchito.
Ponseponse, kusankha mosamala ndi kulinganiza bwino kwa zigawozi kumachita gawo lofunika kwambiri pakutsimikiza magwiridwe antchito, kukhazikika, komanso kusinthasintha kwa Redispersible Emulsion Powder m'magwiritsidwe osiyanasiyana omanga ndi opaka.
