Ufa wa Polima Wosungunukanso (RDP)
Ufa wa Polima Wosungunukanso (RDP)
CAS: 24937-78-8
Ufa wa polima wosungunukanso(RDP) ndi ufa wa latex wouma wothiranso womwe umatha kusungunuka, wopangidwira makampani omanga kuti awonjezere mphamvu za matope ouma, womwe umatha kusungunukanso m'madzi ndikuchitapo kanthu ndi simenti/gypsum ndi stuffing, ndikupanga nembanemba yophatikizika yokhala ndi mphamvu yabwino.
Zimathandiza kuti matope ouma azigwiritsidwa ntchito bwino, monga kutsegula nthawi yayitali, kumamatira bwino ndi zinthu zovuta, kuchepetsa kugwiritsa ntchito madzi, kusweka bwino komanso kukana kugwedezeka.
Pambuyo poumitsa, VAE emulsion imasanduka ufa woyera womwe ndi copolymer ya ethyl ndi vinyl acetate. Imayenda momasuka ndipo ndi yosavuta kuisakaniza. Ikafalikira m'madzi, imapanga emulsion yokhazikika. Pokhala ndi makhalidwe wamba a VAE emulsion, ufa uwu woyenda momasuka umapereka mwayi waukulu wogwirira ntchito ndi kusungira. Ingagwiritsidwe ntchito posakaniza ndi zinthu zina zonga ufa, monga simenti, mchenga ndi zinthu zina zopepuka, ndipo ingagwiritsidwenso ntchito ngati chomangira mu zipangizo zomangira ndi zomatira.
Ufa wa Redispersible Polymer Powder (RDP) umasungunuka m'madzi mosavuta ndipo umapanga emulsion mwachangu. Umathandiza kuti matope ouma azigwiritsidwa ntchito bwino, nthawi yayitali yotsegulira, kumamatira bwino ndi zinthu zovuta, kuchepetsa kugwiritsa ntchito madzi, kusweka bwino komanso kukana kugwedezeka.
Colloid yoteteza: Polyvinyl mowa

KiyiKatundu:
Ufa wa Redispersible Polymer Powder RDP ukhoza kukulitsa kumatirira, mphamvu yopindika, kukana kukwawa, kusinthasintha. Uli ndi rheology yabwino komanso kusunga madzi, ndipo ukhoza kuwonjezera kukana kwa zomatira za matailosi, ukhoza kupanga zomatira za matailosi zokhala ndi mphamvu zabwino kwambiri zosagwa komanso putty yokhala ndi mphamvu zabwino.
Zinthu zapadera:
Ufa wa Redispersible Polymer Powder RDP sukhudza thanzi la rheological ndipo ndi wochepa mpweya woipa,
Ufa wogwiritsidwa ntchito nthawi zonse womwe uli pakati pa Tg. Ndi woyenera kwambiri
kupanga mankhwala amphamvu kwambiri.

Kupaka:
Chogulitsa cha RDP chimayikidwa m'thumba la mapepala la magawo atatu ndi thumba lamkati la polyethylene lolimbikitsidwa, kulemera konse ndi 25kg pa thumba lililonse.
Malo Osungira:
Sungani m'nyumba yosungiramo zinthu zozizira komanso zouma, kutali ndi chinyezi, dzuwa, moto, kapena mvula.
Kima Chemical Co., Ltd. ndi wopanga waluso kwambiri wodziwika bwino ndi Redispersible Polymer Powder (RDP), pakati pa zinthu zina za cellulose ether. Kampaniyo ili ndi mphamvu yopangira matani 20,000 pachaka, ikutumikira mafakitale osiyanasiyana monga zomangamanga, utoto, zodzoladzola, ndi zotsukira. Kudzipereka kwa Kima Chemical kuzinthu zabwino komanso zambiri kumatiyika ngati ogulitsa odalirika a RDP ndi zinthu zina za cellulose ether, zomwe zimakwaniritsa zosowa zosiyanasiyana zamafakitale.
