Monga gawo lofunikira la zida zamakono zomangira, ma polima opangidwanso a polymer powders (RDP) amagwira ntchito yofunikira pazinthu zambiri monga matope, ma putty, grouts, zomatira matailosi ndi makina otenthetsera matenthedwe.Kuthekera kopanga filimu kwa RDP ndichinthu chofunikira kwambiri chomwe chikukhudza mtundu wa chinthu chomaliza.The redispersibility wa ufa pambuyo kusungidwa, zoyendera ndi kusakaniza n'kofunika.Ichi ndichifukwa chake njira zoyezera mwatsatanetsatane komanso mozama ndizofunikira kuti zinthu za RDP zikhale zoyenerera komanso zogwira mtima.
Chimodzi mwamayesero ofunikira kwambiri a luso lopanga filimu ya RDP ndi njira yoyesera yopangira emulsion ya ufa.Njira yoyeserayi imagwiritsidwa ntchito kwambiri pakuwunika kwazinthu komanso njira ya R&D yazinthu za RDP.Njira yoyesera yopangira filimu ya ufa wopangidwanso ndi polima ufa ndi njira yosavuta komanso yosavuta yoyesera, yomwe imatha kuwunika bwino luso lopanga filimu pazinthu za RDP.
Choyamba, redispersibility ya ufa iyenera kuyesedwa musanayambe kuyesa kupanga mafilimu.Kusakaniza ufa ndi madzi ndi kusonkhezera kufalitsanso ma polima particles amaonetsetsa kuti ufa ndi mokwanira zinchito mayeso.
Kenako, Powder Redispersible Polymer Powder Film Formation Njira Yoyeserera ikhoza kuyambika.Kutentha kokhazikika ndi chinyezi chachifupi zimafunikira kuti pakhale malo okhazikika kuti filimuyo ichire bwino.Zinthuzo zimapopera pa gawo lapansi pa makulidwe omwe afotokozedwa kale.Zomwe zili pansi zimatengera zofunikira zomwe zimagwiritsidwa ntchito.Mwachitsanzo, kugwiritsa ntchito matope kungafunike gawo lapansi la konkriti.Pambuyo kupopera mbewu mankhwalawa, zinthuzo zimaloledwa kuti ziume kwa nthawi yoikika, pambuyo pake luso lopanga filimu likhoza kuyesedwa.
Njira Yoyesera Yopanga Mafilimu a Powder Redispersible Emulsion Powder imawunika zinthu zingapo.Izi zikuphatikizapo mapeto a pamwamba, kumamatira ndi kusinthasintha kwa filimuyo.Kumapeto kwa pamwamba kumatha kuyesedwa mwakuwona poyang'ana kapena kugwiritsa ntchito maikulosikopu.Kumamatira kwa filimuyo ku gawo lapansi kunatsimikiziridwa pogwiritsa ntchito kuyesa kwa tepi.Kumamatira kokwanira kumasonyezedwa pamene mzere wa tepi umagwiritsidwa ntchito pazinthu zakuthupi ndipo filimuyo imakhalabe yotsatiridwa ndi gawo lapansi pambuyo pochotsedwa tepiyo.Kusinthasintha kwakanema kungayesedwenso pogwiritsa ntchito mayeso a tepi.Tambasulani filimuyo musanachotse tepiyo, ngati ikhalabe yotsatiridwa ndi gawo lapansi, imasonyeza mlingo woyenera wa kusinthasintha.
Ndikofunikira kutsatira njira zoyenera zoyezera kuti muwonetsetse zotsatira zofananira.Zinthu zingapo zoyeserera kupanga mafilimu ziyenera kukhazikitsidwa kuti zithetse kusiyana pakati pa magulu osiyanasiyana oyesa.Izi zikuphatikizapo njira zokonzekera, kutentha, chinyezi, makulidwe a ntchito ndi nthawi yochiritsa.Kuyesa kwa tepi kumafunikanso kuchitidwa ndi kukakamizidwa komweko kuti mupeze zotsatira zofanana.Kuphatikiza apo, zida zoyeserera ziyenera kuyesedwa musanayesedwe.Izi zimatsimikizira miyeso yolondola komanso yolondola.
Pomaliza, kutanthauzira kolondola kwa zotsatira za Powder Redispersible Emulsion Powder Film Formation Test Method ndikofunikira.Zotsatira zomwe zimapezedwa ndi njira yoyesera kupanga mafilimu ziyenera kufananizidwa ndi miyezo yokhazikitsidwa pakugwiritsa ntchito zinthu zina.Ngati filimuyo ikukwaniritsa zofunikira ndi zofunikira, khalidwe lake limatengedwa kuti ndilovomerezeka.Ngati sichoncho, malondawo angafunike kuyengedwa kwina kapena kusinthidwa kuti apange mawonekedwe ake opanga mafilimu.Zotsatira zoyeserera zingathandizenso kuthana ndi zovuta ndikuzindikira zovuta zilizonse zopanga kapena zolakwika zazinthu.
Mwachidule, njira yoyesera yopanga filimu ya ufa wa polima dispersible imagwira ntchito yofunika kwambiri pakuzindikiritsa mphamvu ya mankhwala a ufa wa polima.Monga chimodzi mwazinthu zofunika kwambiri pazomangira zamakono, luso lopanga mafilimu la RDP ndilofunika kwambiri pakuchita kwake.Kuwonetsetsa kuti luso lopanga filimu ya RDP likukwaniritsa zomwe mukufuna ndikofunikira kuti mukwaniritse bwino ntchito komanso moyo wonse wa chinthu chomaliza.Kutsatira moyenera njira zoyesera ndikofunikira kuti mupeze zotsatira zofananira.Kutanthauzira koyenera kwa zotsatira za mayeso kungaperekenso chidziwitso chofunikira pakupanga ndi kupanga zinthu zapamwamba za RDP.
