Seyakakosha polymer yekuwedzera,redispersible polymer poda (RDP)inoshandiswa zvakanyanya muhunyanzvi hwakaoma dhaka (senge mataira anonamira, plaster madhaka, pasi kugadzirisa zvinhu, nezvimwewo), inonyanya kushandiswa kuvandudza mashandiro edhaka. Ihupfu chena, kazhinji inogadzirwa nekupfapfaidza kuomeswa kwepolymer emulsion. Kuwedzera kwayo kune dhaka rakaoma haingogone kuvandudza kusimba kwechisungo chedhaka, asiwo kunatsiridza mashandiro ayo ekuvaka uye kusimba, iyo ine zvakakosha zvehunyanzvi kukosha uye kukosha kwekushandisa.
1. Zvivakwa zve redispersible latex powder
Redispersible latex poda ndeye polymer zvimedu zvine kunaka kunyungudika kwemvura. Kana mvura yawedzerwa, inogona kuparadzirwa zvakare kuita yunifomu emulsion, nokudaro ichipa dhaka zviri nani zvemuviri. Mapolima akasiyana (akadai se acrylic asidhi, vinyl acetate, chloroprene, nezvimwewo) anogona kugadzira mhando dzakasiyana dzeadzokororwa latex poda ane maitiro akasiyana ekuita. Zvayakanakira zvikuru zvinosanganisira:
Kuwedzeredzwa kunamatira: Redispersible latex poda inogona kunyatso kusimudzira kunamatira pakati pedhaka rakaoma uye substrate (senge mataira, matombo, kongiri, nezvimwewo), uye kuvandudza kunaka kwekuvaka kwedhaka.
Kuvandudzika kuchinjika: Doka rine yakawedzera redispersible latex poda inotsiga uye inochinjika, inogona kuchinjika kudiki deformation, uye kudzivirira kutsemuka.
Kuwedzeredzwa kwekudzivirira kwemvura uye kuramba kwemamiriro ekunze: Iyi mhando yepolymer inogona kuvandudza kugadzikana kwedhaka munzvimbo yemvura, inonatsiridza kusamira kwayo uye kuramba kwemamiriro ekunze, uye inonyanya kukodzera maapplication mumadziro ekunze uye nzvimbo dzakanyorova.
Kuvandudzwa kwemvura uye kushanda kwekushanda: Redispersible latex powder inogona kugadzirisa fluidity uye kuvaka kwekuita kwedhaka, zvichiita kuti zvive nyore kuvaka uye kudzivisa kuputika kukuru kwemvura.
2. Basa rekudhindwa kwelatex poda mune yakakosha dhaka rakaoma
Special yakaoma dhaka kazhinji mhando dhaka rakagadzirirwa kusangana chinokosha pakuvaka zvinodiwa, kusanganisira asi kwete kuganhurirwa uriri kugadzirisa dhaka, mataira adhesive, kunze rusvingo insulation dhaka, yakaoma upfu unhani, etc. Vanowanzoda zviri nani muviri uye kemikari ehupfumi pane zvakajairika dhaka. Basa redhispersible latex poda mune izvi zvigadzirwa rinonyanya kuratidzwa mune zvinotevera zvinhu:
2.1 Kuwedzera kubatana
Mumatairi anonamira, kubatana pakati pematairi uye substrates kunonyanya kukosha. Kunyanya mune dzimwe nzvimbo dzakanyorova, dzinotonhora kana dzakanyanyisa kupisa, kugadzikana kwechisungo kwakabatana zvakananga nekugara kwechinhu. Kuwedzera redispersible latex poda kudhaka kunogona kuwedzera zvakanyanya kushanda kwechisungo chedhaka, kunyanya panzvimbo dzakaita sematairi, matombo kana marble, kudzivirira kupeuka kwechisungo chekubatanidza chinokonzerwa nekuwedzera kwekupisa uye kudonha kana hunyoro.
2.2 Kuvandudza kusamira kwekuputika
Kuwedzerwa kwe redispersible latex powder kunogona kuvandudza kushanduka kwedhaka uye kudzivisa kuputika mudhaka kana yakaoma, kuchinja kwekushisa kana kuzviisa pasi pekunetseka kwemuviri. Kune mashandisirwo akadai sekunze kwemadziro ekugadzirisa dhaka uye elastic plaster dhaka, kushandisa redispersible latex poda inogona zvinobudirira kuvandudza crack resistance.
2.3 Kuvandudza kusamira kwemvura
Iyo redispersible latex poda mudhaka rakaoma inogona kuvandudza zvakanyanya kudzivirira kwayo kwemvura uye anti-kupinza zvivakwa. Munzvimbo dzine hunyoro dzakadai sedzimba dzekugezera nekicheni, zvekunamira mataira uye mamwe madhaka asingapindi mvura zvinoda chivharo chakasimba chekunyorova. Mushure mekuwedzera redispersible latex poda, dhaka rinogona kuramba kupinza hunyoro uye kuwedzera hupenyu hwayo hwesevhisi.
2.4 Kuvandudza kushanda kwedhaka
Kushanda kwedhaka kunobata zvakananga kushanda kwekuvaka uye kunaka kwevashandi vekuvaka. Kuwedzerwa kwe redispersible latex powder kunogona kuvandudza zvakanyanya kushanda kwedhaka, kunyanya kana kuvhara, neine fluidity uye kugadziriswa, zvichiita kuti kuvaka kuve nyore uye kuderedza kuitika kwemvura.
2.5 Kuvandudza kutonhora-kunyungudika kuramba
Mune mamwe maapplication akakosha, senge ekunze madziro ekuisa dhaka uye imwe yekunze yekugadzira dhaka, kuomesa-kunyungudika kuramba kwakakosha. Mushure mekuwedzera redispersible latex poda, kutonhora-kunyungudutswa kwedhaka kunovandudzwa, iyo inogona kuramba kuputika uye kukuvara munzvimbo dzakaderera dzekushisa uye kuenderana nezvinodiwa zvekuvaka kwenzvimbo dzinotonhora.
3. Mienzaniso yekushandisa yakajairika
3.1 Tile inonamira
Mumataira anonamira, kushandiswa kweredispersible latex poda kunogona kuvandudza zvakanyanya kusimba kwechisungo chedhaka, kunyanya kunamatira kwakasimba kumadziro mataira uye pasi mataira. Paunenge uchiisa mataira pasi kana kumadziro, iyo yakanamatira inowanzodikanwa kuti ive nekubatana kwakasimba, nguva yakareba yakazaruka uye yakakwirira kudzivirira kwemvura. Kuwedzerwa kwe redispersible latex powder kunoita kuti tile yekunamatira ikurumidze kusvika kune yakakwana yekubatanidza simba, ichivandudza kugadzikana kwayo kwekuvaka uye kusimba.
3.2 Mudhuri wekunze wekuvharisa madziro
Ekunze madziro evhavha dhaka inoshandiswa pakudzivirira kurapa kwekunze kwemadziro ezvivakwa uye inoda kuve ne-anti-freeze-thaw, kudzivirira kwemvura uye kusagadzikana kwekuputika. Kuwedzerwa kweredispersible latex poda kunosimudzira kuchinjika uye kushorwa kwemvura kwedhaka, nekudaro kudzivirira matambudziko akadai sekudurura uye kuputika kweiyo insulation layer, uye kuwedzera hupenyu hwebasa remadziro ekunze kwechivako.
3.3 Floor kugadzirisa dhaka
Floor repair mortar inoshandiswa mukugadzirisa kwakasiyana-siyana kwepasi nekugadzirisa kuvaka, kunyanya kugadzirisa kwekare. Nekuwedzera redispersible latex powder, kunamatira, fluidity uye kushanduka kwevhu kunovandudzwa, kuve nechokwadi chokuti pasi rekugadzirisa zvinhu zvinogona kuvakwa zvakanaka uye zvinobudirira uye kuchengetedza kugadzikana kwenguva refu.
Sekuwedzera kwakakosha kune yakakosha dhaka rakaoma,redispersible latex podainoita basa rakakosha mukuvandudza mashandiro edhaka, kuwedzera kunamatira kwayo, kusamira kwemvura uye kuramba kutsemuka. Pakati pemhando dzakasiyana dzezvigadzirwa zvedhaka rakaoma, basa rayo uye mabhenefiti ari kuwedzera kuve akakurumbira, kunyanya mundima dzekushandisa dzemataira anonamira, ekunze emadziro ekudzivirira madhaka uye pasi pekugadzirisa madhaka. Sezvo indasitiri yekuvaka ichiramba ichiwedzera zvinodiwa pakuita kwezvinhu, kushandiswa kweredispersible latex poda kuchawedzera.
