Polymer powder (RDP) na-agbanwe agbanwe maka ciment ụrọ

Redispersible polymer powder (RDP) bụ ntụ ntụ na-edozi mmiri nke a pụrụ iji mee ka ihe dị mma na simenti dịkwuo mma. Emere RDP site na polymerizing vinyl acetate na ethylene n'ime emulsion aqueous. Emulsion nke si na ya pụta wee fesa akpọnwụ ka ọ bụrụ ntụ ntụ na-asọ n'efu.

A na-eji RDP mee ihe n'ụdị ngwa agha na ngwaahịa ciment gụnyere:

tile nrapado

ngwa agha na-ebuli onwe ya elu

Putty ntụ ntụ

mgbape mgbape

Ngwa mkpuchi mkpuchi

Plasta dabeere na ciment

Ihe mkpuchi ciment

RDP na-eme ka arụrụ ọrụ nke ngwa agha na simenti dịkwuo mma site na:

mụbaa njide mmiri

Melite ikike ịrụ ọrụ

mụbaa ike tensile

mụbaa ike mgbada

belata shrinkage

mụbaa iguzogide mmiri

mụbaa nguzogide ọkụ

Usoro mmepụta nke RDP bụ nke a:

Vinyl acetate na ethylene bụ polymerized na emulsion mmiri.

A na-efesa emulsion ahụ ka ọ bụrụ ntụ ntụ n'efu.

A na-akwakọba ntụ ntụ ma zigara onye ahịa ya.

Nke a bụ ụfọdụ isi ihe na-emetụta ogo RDP:

Ụdị polymer eji

arọ molekụla polymer

mkpokọta polymer

Nha urughuru ntụ ntụ

ọnụnọ nke adịghị ọcha

RDP bụ ngwaahịa dị iche iche nke enwere ike iji mee ka arụmọrụ nke ngwa ngwa dị iche iche na ngwaahịa ciment dịkwuo mma. Site n'ịghọta usoro mmepụta ihe na isi ihe na-emetụta àgwà, ndị na-emepụta ihe nwere ike ịmepụta RDP nke na-egbo mkpa ndị ahịa.

Nke a bụ ụfọdụ uru agbakwunyere nke iji RDP na ngwa ngwa na ngwaahịa ciment:

RDP na-enyere aka belata oke mmiri dị mkpa na ngwa ngwa na ngwakọta ciment. Nke a nwere ike bute ego nchekwa ego na uru gburugburu ebe obibi.

RDP na-enyere aka melite arụ ọrụ nke ngwa agha na ngwakọta ciment. Nke a nwere ike ime ka itinye ngwaahịa ahụ n'ọrụ dị mfe ma nwee ike belata ihe ize ndụ nke njehie.

RDP na-enyere aka ịbawanye ike na ịdịte aka nke ngwa ngwa na ngwaahịa ciment. Nke a na-agbatị ndụ ngwaahịa ma belata mkpa nrụzi.

N'ozuzu, RDP bụ ngwá ọrụ bara uru nke nwere ike iji mee ka arụmọrụ nke ngwa ngwa na ngwaahịa ciment dịkwuo mma. Site n'ịghọta uru nke RDP na ihe ndị na-emetụta àgwà ya, ndị na-emepụta ihe nwere ike ịme mkpebi mara mma banyere otu esi eji ngwaahịa ahụ iji meziwanye ngwaahịa na usoro ha.
