Redispersible poda hupfu hwakaumbwa nespain yekumesa polymer emulsion, zvakare inonzi yakaoma poda rubha. Iyi poda inogona kukurumidza kuderedzwa kuita emulsion mushure mekubatana nemvura, uye inochengetedza zvivakwa zvakafanana neyeiyo yekutanga emulsion, ndiko kuti, firimu ichaumbwa mushure mekunge mvura yapwa. Iyi firimu ine yakakwirira shanduko, yakakwirira kupisa kudzivirira uye kwakanaka kuramba kune akasiyana siyana substrates. Yakakwira bonding mutsara.

Redispersible latex poda inonyanya kushandiswa muminda yekuvaka yakadai sekunze madziro ekuvharidzira, tile bonding, interface kurapwa, bonding jasi, stucco jasi, kuvaka mukati uye kunze madziro putty, dhongi rekushongedza, nezvimwewo, iro rakawanda rakawanda nzira yekushandisa uye musika wakanaka tarisiro.

Iko kusimudzira uye kushandiswa kweiyo redispersible latex poda yakavandudza zvikuru kushanda kwechinyakare zvekuvakisa zvinhu, yakavandudza zvakanyanya kubatana, kubatana, simba rekushanduka, kurwisa kupikisa, abrasion kuramba, kusimba, nezvimwe. Gadzira zvigadzirwa zvekuvaka nehunhu hwazvo uye zvemhando yepamusoro zvekuona mhando yemapurojekiti ekuvaka.

Redisersible poda

Parizvino inoshandiswa redispersible polymer mapoda muvhu ndeaya: Vinyl Acetate Polyvinyl Acetate (VAC / E), Terpolymer yeEthylene, Vinyl Chloride uye Vinyl Laurate (E / VC / VL), Vinyl Acetate Ester uye ethylene uye yakakwirira fatty acid vinyl ester ternary. Copolymer iribha poda (VAC / E / VeoVa), aya matatu marudzi eiyo redispersible polymer powder anotonga pamusika, kunyanya vinyl acetate uye ethylene Copolymer rubber poda VAC / E, Inzvimbo inotungamira mumunda wepasi rose, uye inomiririra hunyanzvi hwekugadzirisa zvakare. upfu. Kubva pane zvehunyanzvi ruzivo rwekushandisa dhiri-rakagadziriswa ma polymers, ichiri yakanyanya kunaka technical solution:

1. Ndiimwe yeanoshandiswa zvakanyanya ma polima munyika;

2. Ruzivo rwekushandisa zvakanyanya mundima yekuvaka;

3. Iyo inogona kusangana neyemamiriro ezvinhu eheki anodiwa nereti (ndokuti, basa rinodiwa);

4. Polymeric resin nemamwe monomers ine maitiro eiyo yakaderera organic volatile jambo (VOC) uye yakaderera inoshatisa gasi;

5. Iyo ine hunhu hweiyo yakanakisa UV kurwisa, kupisa kwakanaka kupisa uye kugadzira kwenguva refu;

6, nekudzivirirwa kwakanyanya kusvika saponization;

7, ine yakakurisa girazi shanduko tembiricha huwandu (Tg);

8. Ine yakanaka yakakwana kubatana, kuchinjika uye mehendi zvivakwa;

9. Iine ruzivo rwakareba kwazvo mukugadzirwa kwemakemikari uye maitiro ekuchengetedza chengetedzo mukugadzira zvigadzirwa zvemhando;

10.Zviri nyore kusanganisa neinodzivirira colloid (polyvinyl doro) yekuita

Mufananidzo 1 mufananidzo we redispersible poda inotengeswa pamusika

Zvimiro zvehutsi hunodzoreredza

1. Redispersible powder is a-soluble redispersible powder. Iyo kopolymer ye ethylene uye vinyl acetate, ine polyvinyl doro seiyo colloid inodzivirira.

2. VAE redispersible latex powder ine firimu-inogadzira pfuma, 50% aqueous solution inoumba emulsion, uye inogadzira epurasitiki-yakaita firimu mushure mekuiswa pagirazi kwemaawa makumi maviri nemana.

3. Iyo firimu yakaumbwa ine kumwe kuchinjika uye kuramba kwemvura. Inogona kusvika nyika zviyero.

4.Redispersible latex powder ine yakakwira kuita: ine yakakwira yekubatanidza kugona uye yakasarudzika mashandiro, yakanakisa mvura kuramba, simba rakanaka rekubatanidza, uye inopa iyo dhaka yakanakisa alkali kuramba, iyo inogona kunatsiridza iyo duri kunamatira uye kushanduka kwesimba Kuwedzera kune plastiki, pfeka kuramba uye kushanda, ine simba rakasimba kuchinjika mukukanganisa-unopisa dhaka.

Kushandiswa kweiyo redispersible latex poda mune yakaoma poda dhaka:

◆ Masonry dhaka uye plaster dhaka: Redispersible latex upfu ine yakanaka kusagadzikana, kuchengetedza mvura uye kuita chando kuramba, uye yakakwira yekubatanidza simba, iyo inogona kunyatso kugadzirisa kupaza uye kupinda mukati kuripo mune yechinyakare masonry dhaka. Uye zvimwe zvemhando nyaya.

◆ Yega-yekumisikidza dhaka uye pasi zvinhu: Redispersible latex upfu ine simba rakakwirira, kubatana kwakanaka, kunamatira uye kunoda kuchinjika. Inogona kuvandudza kuomerera, abrasion kuramba uye mvura kuchengetwa kwezvinhu. Inogona kuunza rheology yakanakisa, kushanda uye yakanyanya kunaka yekuzvishongedza kuita pasi pevhu rekukanda dhiramu uye screed.

◆ Tile inonamatira, tile yekujoinha mumiriri: Redispersible latex poda ine kunamatira kwakanaka, yakanaka yekuchengetedza mvura, kwenguva refu yakavhurika, kushandurwa, sag kuramba uye yakanaka kudziya-thaw kuramba. Inogona kuunza yakanyanya kunamatira, yakakwirira yekudzivirira kuramba uye yakanaka kuvaka mashandiro kune tira yekunamatira, yakaonda-dura tile inonamira uye yakabatana filler.

◆ Dutu risingabvumirwe nemvura: Redispersible latex poda inosimbisa chibvumirano chesimba kune ese matunhu, inogadzirisa elastic modulus, inowedzera kuchengetedza kwemvura, inoderedza kupinza kwemvura, uye inopa zvigadzirwa nekushanduka kwakanyanya, kukwirira kwemamiriro ekunze uye yakakwirira yekudzivirira mvura zvinodiwa. Iyo ine iyo yakareba-inoguma maitiro eiyo yekuisa chisimbiso pamwe nezvinodiwa zvekubvisa mvura uye kuramba kwemvura.

◆ Kunze kwemadziro kuputira dhaka: Redispersible emulsion upfu mune yekunze madziro ekunze ekuputira system inowedzera kubatana kweiyo dhaka uye inosunga simba kune iyo yekuvhara bhodhi, kuitira kuti iwe ugone kutsvaga kuputira uchidzikisa kushandiswa kwesimba. Kuti uwane inofanirwa kushanda, kusimba shanduko uye kushandisika mune ekunze kumadziro masimbi efurutse zvigadzirwa, unogona kuita kuti zvigadzirwa zvako zvevhu zviite zvakanaka zvinowirirana nehezheni yezvinyorwa zvekuisa uye hwaro. Panguva iyoyowo, zvinobatsirawo kuvandudza zvazvinoita nemishonga uye pamusoro mutswe nemishonga.

◆ Kugadzirisazve Inofa: Redispersible latex poda ine inodikanwa shanduko, shrinkage, yakakwirira kubatana, yakakodzera kutenderera uye inonetesa simba. Gadzira dhaka rekumusoro rinosangana nezvinodikanwa pamusoro pekugadziriswa kongiri isina kurongeka.

◆ Interface Mortar: Redispersible latex powder inonyanya kushandiswa kurapa pamusoro pekongiri, aerated kongiri, lime jecha zvidhinha uye kubhururuka madota zvidhinha, nezvimwewo, kugadzirisa dambudziko iro iro interface harisi nyore kunamatira nekuda kwekuwandisa kwemvura kunyorova kana kutsetseka. , uye plaster layer haina. Drum, kutsemuka, peeling, nezvimwewo. Inoita kuti kunamatirana kusimbe, kwete nyore kudonha uye kuramba kwemvura, uye yakanakisa chando-nyungudika kusagadzikana. Iyo ine kukosha kune mashandiro mashoma, nyore kuvaka.

Redispersible poda inonyanya kushandiswa mu:

Yemukati neyekunze madziro putty poda, mataira anonamira, mataira ejointing mumiriri, yakaoma poda interface mumiririri, kunze kwemadziro kuputira dhaka, yekuzvimiririra-kuyera dhaka, kugadzirisa matope, yekushongedza dhaka, isina mvura dhaka mune yekunze kupisa kupisa kuputira yakaoma-yakasanganiswa dhaka. Ese madhiri anoshandiswa kugadzirisa brittleness uye yakakwirira elastic modulus yetsika simende zvimedu, uye kuvapa zviri nani kuchinjika uye kwakasimba chisungo chisungo simba kuramba uye kunonoka chizvarwa chekuchera matura simende. Nekuti iyo polymer neye mortar fomu inopindira inopindira network, iyo inopfuurira polymer firimu inoumbwa mumapores, ayo anosimbisa kubatana pakati peanogoviga uye anovharira mamwe emapores ari muduri. Naizvozvo, iyo yakagadziriswa dhaka mushure mekuomesa ine zvirinani kuita pane simende dhaka. Pave nekuvandudzwa kukuru.
