Tsatanetsatane wa redispersible emulsion ufa

Redispersible Emulsion Powder (RDP), yomwe imadziwikanso kuti redispersible polima ufa, ndi ufa wopanda madzi, woyera womwe umapezeka mwa kupopera ndi kuyanika emulsion wa vinyl acetate-ethylene copolymer kapena ma polima ena. Ndizowonjezera zosunthika zomwe zimagwiritsidwa ntchito pomanga kuti zithandizire kukonza zinthu monga kumamatira, kusinthasintha, kugwira ntchito, komanso kukana madzi. Nayi tsatanetsatane wa ufa wa emulsion wopangidwanso:

Zolemba:

• Polima Base: Chigawo chachikulu cha RDP ndi polymer yopangira, nthawi zambiri vinyl acetate-ethylene (VAE) copolymer. Ma polima ena monga vinyl acetate-vinyl versatate (VA/VeoVa) copolymers, ethylene-vinyl chloride (EVC) copolymers, ndi ma polima a acrylic angagwiritsidwenso ntchito malinga ndi zomwe mukufuna.
• Protective Colloids: RDP ikhoza kukhala ndi ma colloid oteteza monga ma cellulose ethers (mwachitsanzo, hydroxypropyl methylcellulose), polyvinyl alcohol (PVA), kapena wowuma kuti apititse patsogolo kukhazikika ndi kufalikiranso.

Ndondomeko Yopanga:

1. Emulsion Mapangidwe: The polima amamwazikana m'madzi pamodzi ndi zina monga zoteteza colloids, plasticizers, ndi dispersing wothandizira kupanga khola emulsion.
2. Kupopera Kutaya: The emulsion ndi atomized ndi sprayed mu kuyanika chipinda kumene mpweya otentha amasanduka nthunzi madzi, kusiya zolimba tinthu ta polima. The utsi-zouma particles amasonkhanitsidwa ndi gulu kupeza kufunika tinthu kukula kugawa.
3. Pambuyo pa Chithandizo: Tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono, monga kusinthidwa kwa pamwamba, granulation, kapena kusakanikirana ndi zina zowonjezera kuti zikwaniritse zinthu monga redispersibility, flowability, ndi kugwirizana ndi zigawo zina mu formulations.

Katundu:

• Redispersibility: RDP imawonetsa kusinthika kwabwino m'madzi, kupanga ma dispersibility okhazikika ofanana ndi emulsion yoyambirira pakubwezeretsanso madzi m'thupi. Katunduyu amatsimikizira kugawa kofananira komanso kugwira ntchito mosasintha pamagwiritsidwe ntchito omanga.
• Kupanga Mafilimu: Tinthu tating'onoting'ono ta RDP timatha kulumikizana ndikupanga makanema opitilira apolima akayanika, kupereka zomatira, kusinthasintha, komanso kulimba kwa zida zomangira monga matope, zomatira, ndi ma grouts.
• Kusungirako Madzi: RDP imapangitsa kuti madzi asungidwe m'makina a simenti, kuchepetsa kutayika kwa madzi pakukhazikitsa ndikuchiritsa ndikuwongolera magwiridwe antchito, kumamatira, ndi mphamvu zomaliza.
• Flexibility and Crack Resistance: Filimu ya polima yopangidwa ndi RDP imapereka kusinthasintha komanso kukana ming'alu kuzinthu zomangira, kuchepetsa chiwopsezo cha kusweka ndi delamination.
• Kugwirizana: RDP imagwirizana ndi zomangira simenti zosiyanasiyana, zodzaza, zophatikizika, ndi zowonjezera zomwe zimagwiritsidwa ntchito pomanga, kulola kugwiritsa ntchito mosiyanasiyana komanso kupangidwa.

Mapulogalamu:

• Ma Tile Adhesives ndi Grouts: RDP imathandizira kumamatira, kusinthasintha, komanso kukana madzi mu zomatira matailosi ndi ma grouts, kuwonetsetsa kukhazikitsidwa kokhazikika komanso kokhalitsa.
• Exterior Insulation and Finish Systems (EIFS): RDP imathandizira kusinthasintha, kukana kwanyengo, komanso kukana kwa ming'alu ya zokutira za EIFS, kupereka chitetezo ndi kukongola kwa makoma akunja.
• Ma Compounds Odziyimira pawokha: RDP imathandizira kuyenda bwino, kusanja, ndi kumaliza pamwamba pamagulu odziyimira pawokha, zomwe zimapangitsa kuti pakhale malo osalala komanso osalala.
• Konzani Mitondo ndi Zopereka: RDP imathandizira kumamatira, kulimba, komanso kukana kwa ming'alu pokonza matope ndi ma renders, kubwezeretsa ndi kulimbikitsa nyumba zowonongeka za konkriti.

Redispersible Emulsion Powder (RDP) imagwira ntchito yofunika kwambiri popititsa patsogolo magwiridwe antchito ndi kulimba kwa zida zomanga, zomwe zimathandizira kuti ntchito zomanga zikhale zabwino komanso zautali. Kusinthasintha kwake, kugwirizana kwake, komanso kuchita bwino kumapangitsa kuti ikhale chowonjezera chofunikira pamapulogalamu osiyanasiyana omanga.
