Redispersible emulsion latex poda

Redispersible emulsion latex powder (RDP) yakaoma, iri nyore kubata poda iyo inowanzoshandiswa sechinhu chinowedzera mumatope nemapurasita kuti vawedzere kushanda kwavo. Iyo inonyanya kuumbwa necopolymer yevinyl acetate uye ethylene, iyo inogadzirwa kuburikidza nemaitiro emulsion polymerization.

RDP ihupfu hwakasiyana-siyana uye hunoshanda hwakasiyana-siyana hunopa huwandu hwemabhenefiti mumashandisirwo ekuvaka. Inovandudza kunamatira, kushanduka, kushanda, uye kuchengetwa kwemvura yematope nemapurasita, zvichiita kuti zvishandiswe mumamiriro akasiyana-siyana. RDP inogona zvakare kuwedzera kusimba uye kusimba kwezvivakwa zvekuvaka, zvichiita kuti zvisarambe kuputika, kuderera, uye mamwe maitiro ekukuvadza.

Pamusoro pekushandiswa kwayo mukuvaka, RDP inoshandiswawo mune mamwe maindasitiri, senge machira, zvinonamira, uye machira. Mukuputira, RDP inoshandiswa sebhainda uye firimu-inogadzira mumiriri, inovandudza kunamatira uye kusimba kwependi uye machira. Mukunamatira, RDP inovandudza kusimba uye kunamatira kwekunamatira, zvichiita kuti ive yakakodzera kushandiswa mumhando dzakasiyana dzekushandisa. Mumicheka, RDP inoshandiswa senge saizi mumiriri, inovandudza kusimba uye kusimba kwejira.

Imwe yemabhenefiti akakosha eRDP kugona kwayo kuparadzirwa nyore nyore mumvura mushure mekuoma. Izvi zvinoreva kuti inogona kuchengetwa sehupfu hwakaoma uye wobva wasanganiswa nyore nemvura pazvinenge zvichidiwa, zvichiita kuti ive yakanakira uye inodhura yekuwedzera. Iyo redispersibility yeRDP inotsamira pane akati wandei zvinhu, zvinosanganisira particle size, polymer kuumbwa, uye dhigirii rekuyambuka.

RDP inowanzowedzerwa kune madhaka uye plasters muzvikamu kubva pa 0.5% kusvika 10% nehuremu, zvichienderana nechaiyo application uye inodiwa zvivakwa. Inowanzosanganiswa nezvimwe zvinhu zvakaoma, zvakadai semendi, jecha, uye mafiritsi, zvisati zvasanganiswa nemvura. Musanganiswa unoguma unokwanisa kuiswa kune akasiyana siyana, kusanganisira kongiri, masonry, uye huni.

RDP chinhu chakachengeteka uye chine hushamwari kwezvakatipoteredza chakayedzwa zvakanyanya kuchengetedzeka uye kushanda kwayo. Iyo haina chero zvinhu zvine njodzi uye haina chero yakakosha hutano kana njodzi yezvakatipoteredza. RDP yakatenderwa kuti ishandiswe neanoverengeka masangano anodzora, kusanganisira US Environmental Protection Agency (EPA) uye European Chemicals Agency (ECHA).

Mukupedzisa, redispersible emulsion latex poda ihwo hupfu hwakasiyana-siyana uye hunoshanda huzhinji hunopa huwandu hwemabhenefiti mukuvaka uye mamwe maindasitiri. Kugona kwayo kuvandudza kunamatira, kuchinjika, kushanda, uye kuchengetedza mvura kunoita kuti ive yekuwedzera yakakosha mumadhaka, plasters, machira, anonamira, uye machira. Kusununguka kwayo kwekushandisa, kuchengetedzeka, uye nharaunda-hushamwari inoita kuti ive sarudzo yakasarudzika kune akawanda maapplication.
