Kugwiritsa ntchito ufa wa VAE RDP mumatope osiyanasiyana omanga

1. Chiyambi:

Kutukuka kwa zida zomangira kwapangitsa kuti pakhale zowonjezera monga redispersible polymer powders (RDP), zomwe zimagwira ntchito yofunika kwambiri pakuwongolera matope omangira.Mwa mitundu yosiyanasiyana ya RDP, vinyl acetate-ethylene (VAE) RDP imadziwika chifukwa cha kusinthasintha kwake komanso kuchita bwino pamapangidwe osiyanasiyana amatope.

2. Makhalidwe a VAE RDP ufa:

VAE RDP ufa ndi copolymerized kuchokera vinyl acetate ndi ethylene.Izi zimapanga ufa wabwino, wopanda madzi komanso dispersibility wabwino kwambiri m'madzi.Zofunika kwambiri za VAE RDP zikuphatikiza mphamvu zomangira, kusinthasintha kwabwino komanso kugwirizana ndi zida zosiyanasiyana za simenti.Katunduwa amapangitsa VAE RDP kukhala chowonjezera choyenera pakuwongolera magwiridwe antchito a matope omanga.

3. Kugwiritsa ntchito VAE RDP mumatope osiyanasiyana omanga:

3.1.Zomata matailosi:

VAE RDP imathandizira kulimba kwa zomangira komanso kusinthasintha kwa zomatira matayala, zomwe zimapangitsa kuti chiwonjezeko champhamvu chomangira ndikuchepetsa kusweka.Zomwe zimasunga madzi zimathandizanso kukulitsa nthawi yotsegulira, kupanga matailosi kukhala osavuta kukhazikitsa.

3.2.Kutsekereza khoma ndi kumaliza (EIFS):

Mu EIFS, VAE RDP imathandizira kukana kwadongosolo pakusweka ndi nyengo.Imawonjezera kumamatira kwa primer ku gawo lapansi ndipo imapereka kusinthasintha kuti athe kukulitsa ndi kutsika kwamafuta.

3.3.Kudziyimira pawokha pansi:

VAE RDP imathandizira kuyenda komanso kudziwongolera kwa liner.Imawongolera kusalala kwa pamwamba ndikuchepetsa kuchepa, kupereka maziko ofananirako komanso okhazikika pazophimba pansi.

3.4.Patching mortars:

Pokonza matope, VAE RDP imapangitsa kuti mgwirizano ukhale wolimba komanso mgwirizano, kupititsa patsogolo kukhazikika komanso kukonzanso kwa nthawi yaitali.Zimathandizanso kuwongolera magwiridwe antchito ndikuchepetsa permeability, potero zimakulitsa chitetezo cha chinyezi.

4. Zotsatira za VAE RDP pakuchita matope:

4.1.Mphamvu yomatira:

VAE RDP imapangitsa kuti mgwirizano ukhale wolimba pakati pa matope ndi gawo lapansi, zomwe zimapangitsa kuti pakhale msonkhano wamphamvu, wokhazikika.Iwo akhoza kupanga kusintha filimu pa mawonekedwe kumapangitsanso adhesion pansi pa zinthu zosiyanasiyana.

4.2.Kusunga madzi:

Makhalidwe osungira madzi a VAE RDP amatalikitsa njira ya hydration, zomwe zimapangitsa kuchiritsa bwino komanso kukonza makina amatope.Izi zimatsimikizira kugwira ntchito bwino komanso kukhazikika kwa nthawi yayitali, makamaka m'malo ovuta.

4.3.Makhalidwe a Rheological:

VAE RDP imatha kusintha machitidwe a rheological of mortars, kuwongolera madzimadzi komanso kugwira ntchito.Amachepetsa kulekanitsa ndi kukhetsa magazi pamene amathandizira kumamatira, zomwe zimapangitsa kuti ntchito ikhale yosavuta komanso kukonzekera bwino pamwamba.

Ma ufa a VAE RDP amawonetsa kuthekera kwakukulu pakuwongolera magwiridwe antchito amatope osiyanasiyana omanga.Makhalidwe ake apadera amathandizira kulimbitsa mphamvu zama bond, kusunga madzi komanso machitidwe a rheological, potero kukhathamiritsa kapangidwe ka matope ndikuwongolera kulimba komanso kugwira ntchito.Pomvetsetsa kagwiritsidwe ntchito ka VAE RDP mumitundu yosiyanasiyana yamatope, akatswiri amatha kugwiritsa ntchito zabwino zake kuti akwaniritse zomanga zapamwamba.
