Redispersible latex poda (RDP)chinhu chepolymer chinoshandiswa zvakanyanya muindasitiri yekuvaka, chinowanzo shandiswa sekuwedzera kune putty, coating, adhesive uye zvimwe zvigadzirwa. Basa rayo guru nderokuvandudza kushanduka, kunamatira, kudzivirira mvura uye anti-kuchembera zvinhu zvechigadzirwa.
1. Kuvandudza kusungirirwa kweputty
Kuwedzerwa kweiyo inodhindwazve latex poda kune putty inogona kunyatso kusimudzira kunamatira pakati peputty nepasi pepamusoro (senge simende, gypsum board, nezvimwewo). Mushure mekunge latex poda yanyungudika mumvura, inoumba colloidal chinhu, chinogona kumisa simba rakasimba remuviri uye kemikari yekubatanidza pakati peputty nenzvimbo yepasi. Kuwedzeredzwa kunamatira kunogona kuvandudza zvakanyanya maitiro ekuvaka kweputty, kudzivirira kupaza, kudurura uye mamwe matambudziko, uye kuwedzera hupenyu hwebasa reputty.
2. Kuvandudza kushanduka uye kuputika kupikisa kweputty
Iko kuchinjika kweputty chinhu chakakosha chinokanganisa kusimba kwayo uye kuita kwekuvaka. Redispersible latex poda inoita basa mukuwedzera elasticity uye kuchinjika mu putty. Nekuda kwekuita kweiyo molecular chain ye latex poda, putty inogona kuwana imwe elasticity mushure mekuoma, uye inogona kuchinjika kudiki deformation yepasi pevhu, nekudaro ichidzikisa kuputika kunokonzerwa nezvinhu zvakaita sekuchinja kwekushisa uye kushanduka kwehumidity. Izvi zvakakosha pakunaka uye kusimba kwekushongedza kwemadziro.
3. Kuvandudza kudzivirira kwemvura uye kusagadzikana kwemamiriro ekunze kweputty
Latex poda inogona kunyatso kuvandudza kudzivirira kwemvura kweputty nekuvandudza hydrophobicity ye putty. Traditional putty inotora mvura nyore uye inozvimba munzvimbo ine hunyoro, zvichiita kuti putty layer ibvire uye mold. Mushure mekuwedzera redispersible latex poda, iyo yekunyudza mvura yeputty inodzikiswa zvakanyanya, uye inogona kuramba imwe nhanho yekukukurwa kwemvura. Mukuwedzera, kuwedzerwa kwelatex powder kunovandudzawo kupikisa kwemamiriro ekunze kweputty, kuitira kuti putty irambe ichichengetedza kushanda kwakanaka mushure mekugara kwenguva refu kune nharaunda dzakaoma dzakadai semhepo, mvura uye zuva.
4. Kuvandudza kushanda kwekuvaka kweputty
Redispersible latex poda inogona kuvandudza kuita kwekuvaka kwe putty. Kuwedzerwa kwelatex powder kunoita kuti putty ive nyore kushandisa uye kushanda, kuderedza kuoma uye simba rekushanda kwekuvaka. Iyo fluidity uye operability ye putty ichave iri nani, uye kupfava uye kunamatira kwejasi kunogona kuvandudzwa. Latex poda inoita kuti putty ive neimwe inononoka kurapa chivakwa panguva yekuomeswa, kudzivirira kutsemuka kana kusaenzana kuvharika kunokonzerwa nekunyanya kuoma kweputty panguva yekuvaka.
5. Kuvandudza kupikisa kwechando kweputty
Munzvimbo dzinotonhora, putty inogona kurasikirwa nebasa rayo rekutanga nekuda kwekushisa kwakadzika, uye kunyange kukonzera matambudziko akadai sekuputika uye kudonha. Kuwedzerwa kwe redispersible latex powder kunogona kuvandudza zvakanyanya kusimba kwechando kweputty. Latex poda inogona kuchengetedza kugadzikana kwakanaka kwechimiro pasi peyakadzika tembiricha mamiriro uye kudzivirira matambudziko emhando yeputty nekuda kwechando. Nokudaro, kushandiswa kweputty ine latex powder munzvimbo dzinotonhora dzakadai sekuchamhembe kunogona kuvandudza zvakanyanya kugadzikana uye kuvimbika kwechigadzirwa.
6. Deredza porosity uye uwedzere kuwanda kweputty
Kuwedzerwa kwe latex powder kunogona kunyatso dzikisa porosity ye putty uye kuwedzera kuwanda kwe putty. Munguva yekugadzira firimu rekugadzira putty, latex poda inogona kuzadza madiki pores mukati me putty, kuderedza kupinda kwemhepo nemvura, uye kuwedzera kuvandudza kudzivirira kwemvura, kuramba kusvibiswa uye kukanganisa kuramba kweputty. Iyo compactness ye putty ine kukosha kwakakosha pakusimba kwese kwemadziro, uye inogona zvinobudirira kuvandudza kunaka kwemadziro mushure mekushandisa kwenguva refu.
7. Kuvandudza anti-kusvibiswa pfuma ye putty
Iyo putty layer ndiyo base layer yepende. Kugara kwenguva refu kune guruva, mafuta, acidic uye alkaline zvinhu mumhepo uye zvimwe zvinosvibisa zvinokanganisa mhedzisiro yekupedzisira yepende. Redispersible latex poda inobatsira kuderedza adsorption kugona kweiyo putty pamusoro, nekudaro kuderedza kunamatira kwezvinosvibisa. Izvi hazvisi kungovandudza kusimba kweputty, asiwo kunochengetedza kunaka kwepende yemadziro.
8. Wedzera hupamhi hwekuvakwa kweputty
Sezvo latex poda inogona kunyatso kuvandudza kushanda kwekubatana uye fluidity ye putty, putty uchishandisa latex poda inogona kutsigira yakakura yekuvaka ukobvu. Ichi chiitiko chinonyanya kukosha kune mamwe madziro anoda hukuru hukuru kugadzirisa, izvo zvinogona kuve nechokwadi kuti rusvingo rwakagadziridzwa rwakapfava uye harugone kutsemuka panguva yekushandiswa kwenguva refu.
Kufurira kweredispersible latex podapa putty ine mativi mazhinji, anonyanya kuratidzwa mukuvandudza kunamatira, kuchinjika, kuramba kwemvura, kupikisa chando, kuita kwekuvaka uye anti-kusvibiswa kweputty. Seyakanakisa modifier, latex poda haingogone chete kuvandudza kunaka kweputty uye kuwedzera kusimba kwayo, asiwo kuita kuti putty iwedzere kuchinjika munzvimbo dzakasiyana dzekuvaka. Sezvo zvinodikanwa zveindasitiri yekuvaka zvemhando yekuvaka kwemadziro zvichiwedzera, kushandiswa kweiyo redispersible latex poda kunowedzera uye kwakawedzera, uye kukanganisa kwayo pane zvigadzirwa zve putty kuchawedzera kukosha.
