Cov ntsiab lus ntawm redispersible emulsion hmoov

Redispersible Emulsion Powder (RDP), tseem hu ua redispersible polymer hmoov, yog dawb-ntws, dawb hmoov tau los ntawm cov tshuaj tsuag kom qhuav ib emulsion ntawm yas acetate-ethylene copolymer los yog lwm yam polymers. Nws yog ntau yam additive siv nyob rau hauv cov ntaub ntawv tsim kho los txhim kho cov khoom xws li adhesion, yooj, workability, thiab dej tsis kam. Nov yog cov ntsiab lus ntawm redispersible emulsion hmoov:

Kev sib xyaw:

• Polymer Base: Lub hauv paus tseem ceeb ntawm RDP yog cov khoom siv hluavtaws, feem ntau yog vinyl acetate-ethylene (VAE) copolymer. Lwm cov polymers xws li vinyl acetate-vinyl versatate (VA / VeoVa) copolymer, ethylene-vinyl chloride (EVC) copolymers, thiab acrylic polymers kuj tseem siv tau nyob ntawm seb cov khoom xav tau.
• Kev Tiv Thaiv Colloids: RDP tuaj yeem muaj cov tshuaj tiv thaiv colloids xws li cellulose ethers (xws li, hydroxypropyl methylcellulose), polyvinyl cawv (PVA), los yog hmoov txhuv nplej siab los txhim kho kev ruaj ntseg thiab rov ua dua tshiab.

Txheej txheem ntau lawm:

1. Emulsion Tsim: Cov polymer yog dispersed nyob rau hauv dej nrog rau lwm yam additives xws li tiv thaiv colloids, plasticizers, thiab dispersing agents los tsim ib tug ruaj khov emulsion.
2. Txau kom qhuav: Cov emulsion yog atomized thiab txau rau hauv lub tshuab ziab khaub ncaws uas cov cua kub evaporates cov dej, tawm hauv cov khoom ntawm polymer. Cov tshuaj tsuag-dryed hais yog sau thiab cais kom tau qhov xav tau particle loj tis.
3. Tom qab Kev Kho Mob: Cov khoom qhuav qhuav tuaj yeem dhau los ua cov txheej txheem tom qab kho xws li kev hloov kho saum npoo, granulation, lossis sib xyaw nrog lwm cov tshuaj ntxiv kom zoo dua cov khoom xws li redispersibility, flowability, thiab compatibility nrog rau lwm yam hauv formulations.

Khoom:

• Redispersibility: RDP pom zoo redispersibility nyob rau hauv dej, tsim ruaj khov dispersions zoo ib yam li thawj emulsion thaum rehydration. Cov cuab yeej no ua kom muaj kev faib khoom sib xws thiab kev ua tau zoo ib yam hauv kev tsim kho.
• Zaj duab xis tsim: RDP hais tuaj yeem sib koom ua ke thiab tsim cov yeeb yaj kiab polymer txuas ntxiv thaum ziab, muab adhesion, yooj, thiab ua haujlwm ntev rau cov khoom siv xws li mortars, adhesives, thiab grouts.
• Kev tuav dej: RDP txhim kho cov dej tuav hauv cov txheej txheem cementitious, txo cov dej poob thaum lub sij hawm teeb tsa thiab kho thiab txhim kho kev ua haujlwm, adhesion, thiab lub zog kawg.
• Flexibility thiab Crack Resistance: Lub polymer zaj duab xis tsim los ntawm RDP imparts yooj thiab tawg tsis kam rau cov ntaub ntawv tsim kho, txo qhov kev pheej hmoo ntawm kev tawg thiab delamination.
• Compatibility: RDP yog sib xws nrog ntau yam cementitious binders, fillers, aggregates, thiab additives siv nyob rau hauv kev tsim formulations, tso cai rau ntau yam kev siv thiab formulations.

Daim ntawv thov:

• Pobzeb Adhesives thiab Grouts: RDP txhim kho adhesion, saj zawg zog, thiab dej tsis kam nyob rau hauv cov pobzeb adhesives thiab grouts, kom ntseeg tau tias ruaj thiab kav ntev.
• Sab nrauv Insulation thiab Finish Systems (EIFS): RDP txhim kho qhov yooj yim, huab cua tsis kam, thiab tawg tsis kam ntawm EIFS txheej, muab kev tiv thaiv thiab kev zoo nkauj rau sab nrauv phab ntsa.
• Self-Leveling Compounds: RDP txhim kho flowability, leveling, thiab nto tiav nyob rau hauv tus kheej-leveling tebchaw, ua rau hauv pem teb du thiab theem.
• Kho Mortars thiab Renders: RDP txhim kho adhesion, durability, thiab tawg tiv thaiv nyob rau hauv kho mortars thiab renders, restoration thiab ntxiv dag zog rau cov pob zeb puas.

Redispersible Emulsion Powder (RDP) ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm thiab ua haujlwm ntev ntawm cov ntaub ntawv tsim kho, ua rau muaj txiaj ntsig zoo thiab kev ua haujlwm ntev ntawm lub tsev. Nws versatility, compatibility, thiab kev ua tau zoo ua rau nws muaj txiaj ntsig zoo ntxiv hauv ntau daim ntawv thov kev tsim kho.
