1. Mawu Oyamba
Polystyrene particle insulation mortar ndi zinthu zomwe zimagwiritsidwa ntchito pomanga kunja kwa khoma. Zimaphatikiza ubwino wa polystyrene particles (EPS) ndi matope achikhalidwe, kupereka zabwino zotsekemera komanso makina. Pofuna kupititsa patsogolo ntchito yake yonse, makamaka kupititsa patsogolo kumamatira kwake, kukana ming'alu ndi ntchito yomanga, redispersible latex powder (RDP) nthawi zambiri imawonjezeredwa. RDP ndi emulsion ya polima mu mawonekedwe a ufa omwe amatha kutulutsidwanso m'madzi.
2. Kufotokozera mwachidule za ufa wa latex (RDP)
2.1 Tanthauzo ndi katundu
Redispersible latex ufa ndi ufa wopangidwa ndi kutsitsi kuyanika ndi polima emulsion akamagwira emulsion polymerization. Ikhoza kubwezeretsedwanso m'madzi kuti ipange emulsion yokhazikika yokhala ndi mafilimu abwino opanga mafilimu ndi zomatira. Ma RDP wamba akuphatikizapo ethylene-vinyl acetate copolymer (EVA), acrylate copolymer ndi styrene-butadiene copolymer (SBR).
2.2 Ntchito zazikulu
RDP imagwiritsidwa ntchito kwambiri pazomangira ndipo ili ndi ntchito zotsatirazi:
Limbikitsani kumamatira: Perekani ntchito yabwino yomatira, kupangitsa mgwirizano pakati pa matope ndi gawo lapansi, matope ndi ma polystyrene particles kukhala olimba.
Limbikitsani kukana kwa crack: Limbikitsani kukana kwa matope popanga filimu yosinthika ya polima.
Limbikitsani ntchito yomanga: Wonjezerani kusinthasintha ndi kupanga madzimadzi amatope, osavuta kufalikira komanso mulingo.
Limbikitsani kukana kwamadzi ndi kukana kuzizira kwamadzi: Limbikitsani kukana kwamadzi ndi kukana kwamadzi kuzizira kwamatope.
3. Kugwiritsa ntchito RDP mumatope a polystyrene particle insulation
3.1 Kupititsa patsogolo mgwirizano
Mu polystyrene tinthu kutchinjiriza matope matope, adhesion ndi ntchito yofunika. Popeza tinthu tating'onoting'ono ta polystyrene ndi zida za hydrophobic, ndizosavuta kugwa kuchokera pamatope amatope, zomwe zimapangitsa kulephera kwa insulation system. Pambuyo powonjezera RDP, filimu yopangidwa ndi polima yomwe idapangidwa mumatope imatha kuphimba tinthu tating'onoting'ono ta polystyrene, kuonjezera malo omangira pakati pawo ndi masanjidwewo amatope, ndikuwongolera mphamvu yolumikizirana.
3.2 Kupititsa patsogolo kukana kwa crack
Filimu ya polima yopangidwa ndi RDP imakhala yosinthasintha kwambiri ndipo imatha kupanga ma mesh mkati mwa matope kuti ateteze kufalikira kwa ming'alu. Filimu ya polima imathanso kuyamwa kupsinjika komwe kumapangidwa ndi mphamvu zakunja, potero kuteteza bwino ming'alu yomwe imayambitsidwa ndi kufalikira kwamafuta ndi kutsika kapena kuchepa.
3.3 Kupititsa patsogolo ntchito yomanga
Mtondo wa polystyrene particle Insulation umakonda kusayenda bwino komanso kuvuta kufalikira pomanga. Kuphatikizika kwa RDP kumatha kupangitsa kuti matope azikhala osavuta komanso osavuta kugwiritsa ntchito, ndikupangitsa kuti matopewo akhale osavuta kupanga komanso kukonza bwino ntchito yomanga. Kuonjezera apo, RDP ikhoza kuchepetsanso kugawanika kwa matope ndikupanga kugawa zigawo zamatope kukhala zofanana.
3.4 Kupititsa patsogolo kukana madzi ndi kulimba
Mtondo wa polystyrene particle insulation uyenera kukhala ndi madzi olimba pakagwiritsidwe ntchito kwanthawi yayitali kuti madzi amvula asakokolole zosanjikiza. RDP imatha kupanga hydrophobic wosanjikiza mumtondo kudzera muzinthu zake zopanga filimu, zomwe zimalepheretsa chinyezi kulowa mumatope. Kuphatikiza apo, filimu yosinthika yoperekedwa ndi RDP imathanso kupititsa patsogolo kuzizira ndi kusungunuka kwamatope ndikukulitsa moyo wautumiki wa matope otsekemera.
4. Njira yochitira zinthu
4.1 Zotsatira zopanga mafilimu
Pambuyo RDP imabalalitsidwanso m'madzi mumtondo, tinthu tating'onoting'ono ta polima timaphatikizana kukhala imodzi ndikupanga filimu yopitilira polima. Kanemayu amatha kutseka bwino tinthu ting'onoting'ono tating'onoting'ono mumatope, kuteteza kulowerera kwa chinyezi ndi zinthu zovulaza, ndikuwonjezera mphamvu yolumikizana pakati pa tinthu ting'onoting'ono.
4.2 Kupititsa patsogolo mawonekedwe
Pa kuumitsa ndondomeko ya matope, RDP akhoza kusamukira ku mawonekedwe pakati matope ndi polystyrene particles kupanga mawonekedwe wosanjikiza. Kanemayu wa polima ali ndi zomatira zolimba, zomwe zimatha kusintha kwambiri mphamvu yolumikizirana pakati pa tinthu tating'onoting'ono ta polystyrene ndi masanjidwe amatope ndikuchepetsa kufalikira kwa ming'alu.
4.3 Kusinthasintha kosinthika
Popanga mawonekedwe osinthika a netiweki mkati mwa matope, RDP imawonjezera kusinthasintha konse kwa matope. Maukonde osinthikawa amatha kusokoneza kupsinjika kwakunja ndikuchepetsa kupsinjika, potero kumapangitsa kuti matope asasunthike komanso kukhazikika kwa matope.
5. Zotsatira za kuwonjezera RDP
5.1 Ndalama zowonjezera zoyenera
Kuchuluka kwa RDP yowonjezeredwa kumakhudza kwambiri magwiridwe antchito a matope a polystyrene particle insulation. Nthawi zambiri, kuchuluka kwa RDP yowonjezeredwa kumakhala pakati pa 1-5% ya misa yonse ya simenti. Kuchuluka kwake kukakhala kocheperako, kumatha kupititsa patsogolo mphamvu zomangirira, kukana ming'alu ndi ntchito yomanga matope. Komabe, kuwonjezereka kwakukulu kungapangitse mtengo ndi kukhudza kuuma ndi mphamvu yopondereza ya matope.
5.2 Ubale pakati pa kuchuluka kwa kuchuluka ndi magwiridwe antchito
Mphamvu ya mgwirizano: Pamene kuchuluka kwa RDP kuwonjezeredwa kumawonjezeka, mphamvu yomangirira ya matope imawonjezeka pang'onopang'ono, koma itatha kufika pagawo linalake, zotsatira za kuwonjezera kuchuluka kwa ndalama zomwe zimawonjezeredwa pa kupititsa patsogolo mphamvu zomangira zimakhala zochepa.
Kukana kwa Crack: Kuchuluka koyenera kwa RDP kumatha kupititsa patsogolo kukana kwa matope, ndipo kuwonjezera pang'ono kapena mochulukira kungakhudze zotsatira zake.
Ntchito yomanga: RDP imapangitsa kuti matope asamayende bwino, koma kuwonjezera kwambiri kumapangitsa kuti matopewo azikhala owoneka bwino, zomwe sizingagwire ntchito yomanga.
6. Kugwiritsa ntchito ndi zotsatira zake
6.1 Nkhani yomanga
M'mapulojekiti enieni, RDP imagwiritsidwa ntchito kwambiri pamakina otsekera kunja (EIFS), matope a pulasitala ndi matope omangira. Mwachitsanzo, pakumanga kwakunja kwa khoma lotsekera nyumba yayikulu yamalonda, powonjezera 3% RDP ku matope a polystyrene tinthu tating'onoting'ono, ntchito yomanga ndi kutsekereza kwa matope idakula kwambiri, ndipo chiopsezo chosweka panthawi yomanga chinali. bwino kuchepetsedwa.
6.2 Kutsimikizira koyeserera
Kafukufuku woyeserera adawonetsa kuti matope a polystyrene particle insulation ndi kuwonjezera kwa RDP anali ndi kusintha kwakukulu mu mphamvu yomangira, mphamvu yopondereza komanso kukana ming'alu pamasiku 28. Poyerekeza ndi zitsanzo zowongolera popanda RDP, mphamvu yolumikizira ya RDP-yowonjezera zitsanzo idakula ndi 30-50% ndipo kukana kwa ming'alu kumawonjezeka ndi 40-60%.
Redispersible latex powder (RDP) ili ndi mtengo wofunikira wogwiritsira ntchito mumatope a polystyrene particle insulation. Imawongolera bwino magwiridwe antchito a matope otsekemera powonjezera mphamvu zomangira, kuwongolera kukana kwa ming'alu, kupititsa patsogolo ntchito yomanga, ndikuwongolera kulimba kwa madzi ndi kulimba. Muzochita zogwiritsidwa ntchito, kuwonjezera koyenera kwa RDP kungathe kupititsa patsogolo kukhazikika ndi kukhazikika kwa makina otsekemera, kupereka chitsimikizo chofunikira chomanga kusungirako mphamvu ndi chitetezo cha zomangamanga.
