(1 Mawu Oyambirira
Redispersible Polymer Powder (RDP) ndi ufa wosinthidwa wa polima womwe ukhoza kutulutsidwa mu emulsion pamene umalowa m'madzi. Amapangidwa ndi kuyanika kupopera ndipo makamaka amapangidwa kuchokera kuzinthu zoyambira monga ethylene vinyl acetate (VAE), acrylate copolymer ndi styrene-butadiene. M'makampani omangamanga, RDP yakhala yowonjezera yofunikira ndipo imagwiritsidwa ntchito kwambiri muzinthu zopangira simenti ndi gypsum, matope owuma, zomatira zamataipi a ceramic, pansi pawokha, makina otsekemera akunja ndi zina.
(2) Kupititsa patsogolo mgwirizano
1. Sinthani kumamatira pakati pa magawo
RDP ikagwiritsidwa ntchito pazida zopangira simenti ndi gypsum, imatha kupititsa patsogolo kwambiri zomangira zazinthuzo. Izi ndichifukwa choti RDP imatha kufalitsanso kupanga emulsion panthawi ya hydration, potero kupanga filimu yofananira polima pamwamba pa gawo lapansi. Kanemayu amatha kulowa mu pores ndi ming'alu yaying'ono ya gawo lapansi ndikuwonjezera kutsekeka kwamakina pakati pa magawowo, motero kumapangitsa kuti mgwirizano ukhale wolimba.
2. Sinthani mphamvu yolumikizana pakati pa zigawo
M'magawo osiyanasiyana, monga pansi pawokha, pulasitala, ndi zina zotero, RDP imatha kupititsa patsogolo mphamvu yomangira pakati komanso kupewa kusenda pakati. Popanga mawonekedwe olimba a polima network, zimatsimikizira magwiridwe antchito abwinoko pakati pa zigawo zosiyanasiyana ndikupereka mawonekedwe okhazikika.
(3) Sinthani kukana kwa mng'alu ndi kusinthasintha kwazinthu
1. Chepetsani kupezeka kwa ming'alu
Panthawi yowumitsa, zipangizo zopangira simenti zimakhala zosavuta kung'amba chifukwa cha kutuluka kwa madzi ndi kusintha kwa kutentha. Kuphatikiza kwa RDP kumatha kuchepetsa kuchitika kwa ming'alu. Filimu ya polima yopangidwa ndi RDP itatha kuumitsa imatha kuyamwa ndikuchepetsa kupsinjika kwazinthu ndikuchepetsa kuchitika kwa ming'alu. Izi ndizofunikira makamaka pamakina otchinjiriza pakhoma ndi zomatira matailosi, chifukwa izi zimayang'anizana ndi kutentha komanso kusintha kwa chinyezi.
2. Limbikitsani kusinthasintha kwa zipangizo
Zida zomangira ziyenera kukhala ndi kusinthasintha kwina pakumanga ndikugwiritsa ntchito kuti zigwirizane ndi zopindika zazing'ono zazinthu zoyambira popanda kusweka. RDP imatha kusintha kwambiri kusinthasintha kwa zinthuzo, kulola kuti zinthuzo zikhale ndi mphamvu zina zopindika pansi pa zochita za mphamvu zakunja popanda kuwononga, motero kuwonjezera moyo wautumiki wa zinthuzo.
(4) Kupititsa patsogolo ntchito yomanga
1. Kupititsa patsogolo ntchito yomanga
RDP ikhoza kupititsa patsogolo ntchito yomanga matope owuma. Ikhoza kuonjezera kusungunuka ndi kugwiritsira ntchito matope, kuti zikhale zosavuta kusakaniza, kufalikira ndi msinkhu. Izi ndizofunikira makamaka pa zomatira za matailosi ndi malaya a pulasitala omwe amafunikira kusamalidwa bwino.
2. Wonjezerani maola otsegulira
Panthawi yomanga, nthawi yotseguka ya zinthu (ndiko kuti, nthawi yomwe zinthuzo zimagwira ntchito) ndizofunikira kwambiri. RDP imatha kukulitsa nthawi yotsegulira posintha kasungidwe ka chinyezi pamatope, kupatsa ogwira ntchito yomanga nthawi yochulukirapo kuti asinthe ndi kukonza, komanso kukonza bwino ntchito yomanga.
(5) Sinthani kukhazikika komanso kukana kwa dzimbiri kwamankhwala
1. Limbikitsani kukana madzi
RDP imatha kupititsa patsogolo kukana kwamadzi pazinthu zopangira simenti. Amapanga filimu wandiweyani wa polima pamwamba pa zinthuzo kuti achepetse kulowa ndi kuyamwa kwa chinyezi ndikupewa kuwonongeka kwazinthu zomwe zimachitika chifukwa cha chinyezi. Katunduyu ndi wofunikira kwambiri pazida zomwe zimakhudzidwa ndi chinyezi kwa nthawi yayitali.
2. Kupititsa patsogolo kukana kwa dzimbiri kwa mankhwala
Zomangamanga zidzawonekera kuzinthu zosiyanasiyana zamakina pakagwiritsidwe ntchito, monga ma acid, alkalis, salt, etc. RDP ikhoza kupititsa patsogolo kukana kwa zinthuzo ku dzimbiri za mankhwala ndi kuchepetsa kuwonongeka kwa zipangizo ndi mankhwala, potero kuwonjezera moyo wautumiki wa zinthuzo. Izi ndizofunikira kwambiri pazogwiritsa ntchito monga zida zakunja zotchinjiriza khoma ndi zida zapansi za mafakitale.
(6) Kukonda chilengedwe
1. Kuchepetsa kuwononga chilengedwe
Monga zinthu zoteteza chilengedwe, njira yopangira RDP ndi yogwirizana ndi chilengedwe ndipo ingachepetse kuwononga chilengedwe. Kuphatikiza apo, imatha kuchepetsa kusweka kwa zinthu ndi kuwonongeka pakagwiritsidwe ntchito, potero kuchepetsa kukonzanso ndikusinthanso, komanso kuchepetsa kuwononga zinthu komanso kulemetsa zachilengedwe.
2. Chepetsani kutulutsa kwamtundu wa volatile organic compound (VOC).
Monga chinthu chopanda zosungunulira, RDP imatha kuchepetsa kwambiri mpweya wa volatile organic compounds (VOC) muzomangamanga, zomwe sizimangokwaniritsa zofunikira zachitetezo cha chilengedwe, komanso zimathandizira kuti mpweya wabwino wa malo omanga ukhale wabwino.
(7) Phindu lazachuma
1. Kuchepetsa ndalama zonse
Ngakhale kuti RDP yokha ikhoza kuwonjezera ndalama zina zamtengo wapatali, mwa kuwongolera magwiridwe antchito ndi kukhazikika kwa zinthuzo, mtengo wokonzanso ndikusinthanso zinthuzo ukhoza kuchepetsedwa, zomwe zimatha kuchepetsa mtengo wonse pakapita nthawi. RDP imatha kupanga zida zomangira kukhala zogwira mtima kwambiri komanso moyo wautali wautumiki, kuchepetsa zomanga zachiwiri ndi zinyalala zakuthupi, potero zimabweretsa phindu pazachuma.
2. Kupititsa patsogolo luso la zomangamanga
Kugwiritsa ntchito RDP kumatha kukonza bwino nyumbayo ndikuchepetsa kukonzanso ndi kukonza ndalama zomwe zimadza chifukwa cha zovuta zakuthupi. Kwa omanga ndi maphwando omanga, zida zomangira zapamwamba zimatanthawuza madandaulo ocheperako komanso zovuta zosamalira, potero zimakulitsa kukhulupirika ndi mpikisano wamsika wa polojekitiyi.
(8) Zitsanzo zogwiritsira ntchito
1. Zomatira matailosi
Kuonjezera RDP pa zomatira matailosi kumatha kukulitsa mphamvu yomangirira pakati pa matailosi ndi gawo lapansi, kupititsa patsogolo magwiridwe antchito a zomatira, ndikusintha magawo osiyanasiyana ndi momwe zimakhalira.
2. Njira yotchinjiriza kunja kwa khoma
M'makina akunja otchingira khoma, RDP imatha kupititsa patsogolo kumamatira pakati pawotchingira ndi zokongoletsera, kupititsa patsogolo kukhazikika kwadongosolo, ndikuwongolera kukana kwa ming'alu ndi kulimba kwa dongosolo.
3. Pansi pawokha
Kugwiritsiridwa ntchito kwa RDP pazipinda zodzipangira nokha kumatha kukulitsa kusalala ndi kulimba kwa pansi, kupititsa patsogolo ntchito yomanga, komanso kuzolowera zovuta zapansi.
Redispersible latex ufa uli ndi maubwino ambiri pakumanga. Ikhoza kupititsa patsogolo kugwirizanitsa kwa zinthuzo, kupititsa patsogolo kukana kwa mng'alu ndi kusinthasintha, kupititsa patsogolo ntchito yomanga, kupititsa patsogolo kulimba ndi kukana kwa dzimbiri, ndipo kumakhala ndi ubwino wa chilengedwe ndi zachuma. Pazomangira zamakono, kugwiritsa ntchito RDP kwakhala chimodzi mwazinthu zofunika kwambiri pakuwongolera magwiridwe antchito ndi zomangamanga. Ndi kupita patsogolo kwaukadaulo komanso kukulitsidwa kosalekeza kwa ntchito, RDP iwonetsa phindu lake lapadera ndi zabwino zake pazomanga zambiri.
