Redispersible polymer poda (RDP) chinhu chekuvaka chinowedzera chinoshandura emulsion yepolymer kuita fomu yehupfu kuburikidza nekupfapfaidza kuomesa maitiro. Kana hupfu uhu hwasanganiswa nemvura, hunogona kuparadzirwa zvakare kuti hugadzire latex suspension yakagadzikana inoratidza zvinhu zvakafanana neyekutanga latex. Nyaya iyi yakashandiswa zvakanyanya muindasitiri yekuvaka, kunyanya mukugadzira dhaka rakaoma uye zvinonamira zvekuvaka.
1. Basic ingredients uye gadziriro yekugadzirira
Izvo zvekutanga zvinongedzo zveredispersible latex poda zvinowanzo sanganisira polymer matrix, inodzivirira colloid (senge polyvinyl doro), additives (senge defoamers uye plasticizers) uye mamwe inorganic fillers (senge calcium carbonate). Iyo polymer matrix ndiyo chikamu chikuru che redispersible latex poda. Mapolima akajairika anosanganisira ethylene-vinyl acetate copolymer (EVA), acrylate copolymer uye styrene-butadiene copolymer.
Maitiro ekugadzira redispersible latex poda anonyanya kusanganisira anotevera matanho:
Emulsion polymerization: Kutanga, gadzirira emulsion ine mvura ine polymer. Kuburikidza ne emulsion polymerization tekinoroji, mamonomers anogadzirwa mumvura kuti agadzire emulsion-senge polymer particles.
Kupfapfaidza kuomesa: Iyo yakagadzirwa polymer emulsion yakaomeswa kuburikidza nespray dryer. Iyo emulsion inopfapfaidzwa mumadonhwe akanaka uye nekukasira kuomeswa kuita zvidimbu zvepolymer.
Kurapa kwepamusoro: Munguva kana mushure mekuoma, mamwe majekiseni ekurapa epamusoro (senge polyvinyl doro) anowanzowedzerwa kuti avandudze kugadzikana uye kudhindwa kwehupfu.
2. Maitiro ekuita
Redispersible latex poda ine zvakawanda zvakasiyana zvivakwa zvinoita kuti ive yakakurumbira mukuvaka maapplication:
Redispersibility: Iyi poda inogona kuparadzirwa zvakare mumvura uye kudzorerwa kune emulsion state, ichipa zvinhu zvinhu zvakafanana nekutanga emulsion.
Kuwedzeredzwa kunamatira: Mune yakasanganiswa yakaoma dhaka kana inonamira, latex poda inogona kuvandudza kunamatira pakati pechinhu uye substrate.
Kuvandudzwa kuchinjika: Inogona kuvandudza kuchinjika uye kutsemuka kuramba kwechinyorwa uye kuderedza njodzi yekupwanya kunokonzerwa nekushushikana kushushikana kana shanduko yekushisa.
Kuramba kwemvura uye kuramba kwemamiriro ekunze: Redispersible latex poda inogona kuvandudza kudzivirira kwemvura uye kuramba kwemamiriro ekunze kwezvinhu, zvichiita kuti zvigadzikane mumamiriro ekunze ane hunyoro kana anoshanduka.
Zviri nyore kuvaka: Zvishandiso zvine redispersible latex poda yakawedzerwa zvine kushanda kuri nani panguva yekuvaka, senge yakavhurika nguva yakareba uye chiyero chiri nani.
3. Nzvimbo dzekushandisa
Redispersible latex poda ine huwandu hwakasiyana hwekushandisa muindasitiri yekuvaka, kunyanya kusanganisira zvinotevera zvinhu:
Tile adhesive: Latex poda inogona kuvandudza zvakanyanya kusimba kwekubatanidza uye kuchinjika kwematairi ekunamatira, uye yakakodzera kune akasiyana substrates uye mataira marudzi, kunyanya mugeothermal pasi uye kunze kwemadziro ekudzivirira masisitimu.
Mvura isingapindi mvura: Mumuumbi wedhaka rekusapinda mvura, latex poda inogona kukwidziridza kutsemuka uye kusapinda mvura kwedhaka, zvichiita kuti iite zvakanaka munzvimbo dzine hunyoro dzakadai semba yekugezera nekicheni.
Zvishandiso zvepasi: Latex poda inogona kuvandudza kuyerera uye kupfava kwezvinhu zvekuzvimisa pasi, kuve nechokwadi chekuti pasi pakatsetseka, yakasimba uye haisi nyore kutsemuka mushure mekuvaka.
External wall insulation system: Mune ekunze madziro ekudzivirira masisitimu (akadai sekunze kwemadziro ekudzivirira uye emukati masisitimu ekudzivirira), latex poda inogona kuvandudza kusimba kwekubatanidza pakati pebhodhi rekudzivirira uye base layer, kuve nechokwadi kutendeseka uye kusimba kweiyo insulation system.
Kugadzirisa dhaka: Latex poda inobata basa mukusimudzira kusungirirwa uye kutsemuka kusagadzikana mukugadzirisa dhaka, kuve nechokwadi kusanganiswa kwakanaka kwenzvimbo yekugadzirisa ine chimiro chepakutanga uye kuwedzera hupenyu hwebasa rechivako.
4. Kuchengetedzwa kwezvakatipoteredza uye kusimba
Nekuvandudzwa kwekuziva kwezvakatipoteredza, hunhu hwekuchengetedza kwezvakatipoteredza hwezve dispersible latex poda yakabhadharwawo. Vagadziri vazhinji vanotora maitiro ekugadzira ane hushamwari kwezvakatipoteredza kuti aderedze kushandiswa kwezvinhu zvinokuvadza, uye chinhu ichi chinogona kuderedza marara uye kugadzirisa zviwanikwa zvekushandisa zvakanaka mukuvaka zvikumbiro. Pamusoro pezvo, nekuvandudza mashandiro ezvivakwa zvekuvaka, latex poda inogona zvakare kuderedza mutengo wekugadzirisa uye kushandiswa kwesimba kwezvivakwa, nekudaro zvichibatsira mukuvandudzwa kwezvivakwa zvinogara.
5. Tarisiro yemusika uye mafambiro ebudiriro
Nekuwedzera kuri kuita kudiwa kwepamusoro-kuita uye zvakatipoteredza zvine hushamwari zvinhu muindasitiri yekuvaka, tarisiro yemusika yezve inodispersible latex poda yakakura. Mafambiro ekuvandudza mune ramangwana anosanganisira:
Performance optimization: Ramba uchivandudza mashandiro e latex poda, sekusimudzira kupikisa kwemamiriro ekunze uye kuramba kwemakemikari, kusangana nezvinodiwa zveakasiyana mashandisirwo mamiriro.
Kugadzirwa kwegirini: Deredza iyo kabhoni tsoka uye nharaunda kukanganisa kwemaitiro ekugadzira kuburikidza negirinhi chemistry uye inoenderera maitiro.
Zvigadzirwa zvakagadzirirwa: Ipa zvakagadziridzwa latex poda zvigadzirwa zvinoenderana nezvinodiwa chaizvo nevatengi kuti vajairane neakakosha maficha ekushandisa, senge yakaderera-tembiricha yekuvaka, yakakwirira-humidity nharaunda, nezvimwe.
Redispersible latex poda, sechinhu chakakosha chekuvaka chinowedzera, ine huwandu hwakasiyana hwemashandisiro ekushandisa. Kuita kwayo kwakanakisa hakungonatsiridza kunaka kwezvinhu zvekuvaka, asi zvakare inosimudzira indasitiri yekuvaka kuti ikure mune yakawedzera hushamwari uye yakagadzikana kutungamira.
