Iyini i-RDP Powder ye-Gypsum Based Plasters? Umhlahlandlela ophelele

I-RDP Powder ye-Gypsum Based Plasters: Incazelo Eyinhloko

I-RDP impushana ama-plaster asekelwe ku-gypsum iyi-free-flowing, impushana emhlophe eyenziwe ngokuyinhloko kusuka ku-a i-vinyl acetate-ethylene (IZINYAWO) i-copolymer. Uyengeza ekuhlanganiseni okomile kwe-gypsum formulations. Lapho uzosebenzisa kamuva ngamanzi. Lapho ukhonkolo sesomile, izinhlayiya ze-RDP zihlangana zibe ifilimu efana nepulasitiki kuyo yonke i-gypsum matrix eqinile. Lolu shintsho olulodwa lunikeza izakhiwo ze-plaster ezingakwazi ukuzifinyelela ngokwazo.

Impushana emhlophe egeleza yamahhala ye-RDP vinyl acetate-ethylene copolymer yokwenza udaka lwe-gypsum.

Indlela ye-RDP Powder ye-Gypsum Based Plasters

Sonke isikhwama se I-RDP powder yamapulasi asekelwe ku-gypsum iqukethe izigidi zama-polymer spheres amancane. Lezi zinhlayiya zomiswe nge-emulsion. Isihluthulelo izinyathelo chaza ukuthi isebenza kanjani.

  • Ukuxuba kanye Nokuhlakazeka: Uma uhlanganisa impushana eyomile ekhonjiwe namanzi, izinhlayiya ze-polymer kufanele ngokuphelele hlukana. Udinga ukugoqa ngokuphelele.
  • Ukugcina Amanzi: Izinhlayiya ze-polymer zivimba ezinye izimbotshana kusimende esisha. Lokhu kubamba amanzi eduze kwamakristalu e-gypsum isikhathi eside
  • Ukwakhiwa Kwefilimu: Amanzi ayahwamuka. Izinhlayiya ze-polymer ezihlakazekile ziyathinta, khubaza, futhi uhlangane ube okuqhubekayo, ifilimu engancibiliki emanzini.
  • Ukubhula
  • Ukukhuthazwa kokunamathela: Ifilimu ye-polymer nayo manzi i-substrate (ukhonkolo, isitini, i-drywall) kangcono kune-gypsum iyodwa.

Izinzuzo ze-RDP Powder ye-Gypsum Based Plaster

Umqondo uqondile: i-plaster ngaphandle kwe-RDP iyaphuka futhi amanzi-ebucayi. Engeza I-RDP powder yamapulasi asekelwe ku-gypsum, futhi uthola ukuthuthukiswa okuthuthukile.

1. Ukunamathela kanye Nokubumbana (Amakhulu Amabili)

I-Gypsum iyodwa ayinamathele kahle kusimende obushelelezi noma ezindaweni ezipendiwe. I-RDP inikeza i-polymer iqinisekisa izibopho ze-plaster odongeni. I-plaster inamathela ngokwayo (ukubumbana), ukuvimbela i-delamination

2. Ukuvumelana nezimo kanye ne-Crack Resistance

I-Gypsum ehlanzekile icishe ibe ne-zero tensile flexibility. udonga lunyakaza kancane, ukhonkolo uyaqhekeka. I i-polymer ifilimu inikeza ukhonkolo oqinile ipulasitiki, ikhwalithi eguquguqukayo. It uyamunca ukunyakaza okuncane kwe-substrate ngaphandle kokuqhekeka

3. Ukuxosha Amanzi

I-Gypsum iyancibilika emanzini. Ezindlini zokugezela ezinomswakama noma emakhishini, ukhonkolo olujwayelekile luyathambisa noma luncibilike. I-RDP kunciphisa ukumuncwa kwamanzi futhi kuthuthukisa ukuxosha amanzi. Ama-block pores, ukuvimbela amanzi awuketshezi kusuka ukungena.

4. Ukumelana ne-Abrasion

Izindawo ze-Gypsum ziklwebha kalula. Ifilimu ye-polymer ngaphakathi Impushana ye-RDP yamapulasi asekelwe ku-gypsum isebenza njengesibophezelo esiqinile. Imelana nokuklwebheka nokuklwebheka. Ingaphezulu lithinta ukuhlanza nsuku zonke.

5. Ukusebenziseka

Izinhlayiya ze-polymer zisebenza njengama-bearings amabhola amancane emiksini entsha. Lokhu kuthuthukisa ukusebenza ngaphandle kokwengeza amanzi engeziwe. Uthola i-creamier, i-trowel esakazeka kakhudlwana.

Ukushintshaniswa Kwesilinganiso kanye Nokusebenza

Kufanele ulinganise I-RDP powder yamapulasi asekelwe ku-gypsum ngemithamo ejwayelekile phakathi 1% futhi 5% ngesisindo sempushana eyomile eyomile. Sikhuluma ngezilinganiso:

  • 1-2%: Ukuthuthukiswa kokunamathela okuncane, ukunamathela okuthile nokumelana namanzi. Ifanele amajazi e-skim angaphakathi ingozi yomswakama ephansi iphansi.
  • 3-4%: Ukuguquguquka okuphawulekayo nokunamathela okuphezulu. Okujwayelekile kwezindonga zangaphakathi, ukwahlukanisa nalapho kubalulekile ukumelana nokuqhekeka.
  • 4-5%: Ubuningi bokuxosha amanzi kanye nokuguquguquka. Okokunikezwa kwangaphandle noma izindawo ezinomswakama kakhulu. Ukuhwebelana? Amandla acindezelayo ayehla. i-gypsum iba thambile. Uthola ukuguquguquka kodwa ulahlekelwe ubulukhuni.

Ungeqi 5% ezindaweni eziningi ze-gypsum spray noma i-trowel applications. I-plaster ingase ihlale ithambile kakhulu ukuba ingafakwa esihlabathini noma

I-plaster ethambile ethambile kakhulu ukuthi ingabi nesihlabathi ngemuva kokuyidlula 5% isicelo se-gypsum spray sidlula umkhawulo.

Ukuhambisana Nezinye Izithasiselo Ze-Gypsum

I-RDP powder yamapulasi asekelwe ku-gypsum isebenza ngezithasiselo ezijwayelekile ze-gypsum. Nansi ingqondo

    I-Cellulose Ethers (I-HPMC/MHEC: Lawa ma-thieners abamba amanzi isikhathi eside sokusebenza. I-RDP ayingqubuzani; empeleni kuyazuza ekugcineni amanzi. Zisebenziseni ndawonye.
  • Abalindi: Setha isikhathi esimisiwe. Umsebenzi we-RDP uzimele. Ungakwazi ukuhlehlisa isethi ngaphandle kokuphazamisa ukwakheka kwefilimu ye-polymer.
  • Ama-thickeners: Lungisa i-viscosity. I-RDP ayishubi ingxube. Engeza i-thickener ehlukile ukuvumelana kwakho okuhlosiwe

    • Isicelo-Iseluleko Esiqondile

    Impushana ye-RDP yangaphakathi I-Interior Gypsum Renders kanye ne-Skim Coats: 2-3% I-RDP inikeza ukunamathela okuhle nokumelana nokuqhekeka. Sebenzisa umthamo ophansi uma i-substrate ilukhuni noma imunca.

    I-Exterior Gypsum Renders: Izimo zangaphandle zidinga 4-5% I-RDP. Okuqukethwe kwe-polymer okuphezulu kuvikela emvuleni kanye nemijikelezo yokuqhwaza. Kodwa phawula: I-gypsum yangaphandle iyingozi kune-renders esekwe kusimende. Faka ijazi le-primer kuqala

    I-Gypsum-based Tile Adhesives: Ukuvumelana nezimo okuphezulu kubalulekile. Sebenzisa 4% RDP.5-5% RDP. I-polymer ihlinzeka induku emanzi futhi isibopho sokugcina edingekayo kumathayili e-ceramic ezindongeni.

    Isitoreji Nokuphatha

    • Igcine Yomile: Impushana ye-RDP imunca umswakama emoyeni. Uma sekunomswakama, kwenza izigaxa ezingaphinde zihlakazeke. Gcina kuvaliwe, izimo ezomile.
    • Hlanganisa Ngokufanelekile: Faka njalo impushana ye-RDP kumpushana wegypsum owomile kuqala. Bese wengeza amanzi. Uma wengeza i-RDP emanzini, iyaqumba.
    • Ikhwalithi Yokuhlakazwa kabusha: Izimpushana ze-RDP ezishibhile aziphinde zihlakazeke ngokugcwele. Umphumela? , ifilimu enamabala. Faka imali kwikhwalithi ephezulu I-RDP powder yamapulasi asekelwe ku-gypsum ukuze uthole imiphumela engaguquki.

      • Ithebula: Ireferensi esheshayo ye-RDP Powder ku-Gypsum Plasters
