Redispersible polymer ntụ ntụ usoro mmepụta

Okwu mmalite

Redispersible polymer powder (RDP) bụ ụdị polymer ntụ ntụ nke nwere ike ịgbasa na mmiri iji mepụta emulsion kwụsiri ike. A na-eji ya eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu dị ka ihe mgbakwunye iji melite arụmọrụ nke ihe ndị dabeere na ciment. A na-emepụta RDP site na usoro a maara dị ka ịgbasa mmiri, nke gụnyere atomization nke ngwọta polymer n'ime ntụ ntụ dị mma. A na-akpọzi ntụ ntụ ma gwerie ya ka ọ bụrụ nha nha nke achọrọ.

Usoro mmepụta nke RDP gụnyere ọtụtụ usoro, gụnyere nhọrọ polymer, nkwadebe ngwọta, atomization, ihicha, na igwe igwe. Ogo nke ngwaahịa ikpeazụ na-adabere na ịdị mma nke akụrụngwa na usoro usoro eji eme ihe n'oge mmepụta.

Nhọrọ polymer

Nzọụkwụ mbụ na usoro mmepụta nke RDP bụ nhọrọ nke polymer kwesịrị ekwesị. Nhọrọ nke polymer dabeere na ihe ndị a chọrọ nke ngwaahịa ikpeazụ, dị ka mmiri na-eguzogide mmiri, adhesion, na mgbanwe. Ihe ndị a na-ejikarị eme ihe maka mmepụta RDP bụ vinyl acetate-ethylene copolymers, acrylic copolymers, na styrene-butadiene copolymer.

Nkwadebe ngwọta

Ozugbo ahọpụtara polymer, a na-agbaze ya na ihe mgbaze iji mepụta ngwọta. Ihe mgbaze a na-ejikarị eme ihe maka mmepụta RDP bụ mmiri na ihe mgbaze dị ka ethanol na isopropanol. Ntụnye nke ngwọta polymer na-adịkarị n'etiti 10-20%.

Atomization

Nzọụkwụ ọzọ na usoro mmepụta nke RDP bụ atomization. Atomization bụ usoro nke imebi ihe ngwọta polymer n'ime obere ụmụ irighiri mmiri. A na-emekarị nke a site na iji nozzle dị elu ma ọ bụ atomizer rotary. A na-akpọzi ụmụ irighiri mmiri ahụ n'ime mmiri na-ekpo ọkụ ka ọ bụrụ ntụ ntụ.

Ịkpọ nkụ

A na-akpọzi ntụ ntụ na mmiri na-ekpo ọkụ iji wepụ ihe mgbaze. A na-emekarị usoro ihicha na okpomọkụ n'etiti 80-120 Celsius. Oge ihicha na-adabere n'ụdị polymer ejiri mee ihe, ntinye nke ngwọta, na nha nha nke achọrọ.

Ịgba igwe

Nzọụkwụ ikpeazụ na usoro mmepụta nke RDP bụ igwe nri. Egwe ọka bụ usoro egweri ntụ ntụ ka ọ bụrụ nha nke kacha mma. A na-ejikarị igwe igwe hama ma ọ bụ igwe igwe bọọlụ eme nke a. Ogo urughuru nke ngwaahịa ikpeazụ na-adịkarị n'etiti 5-50 microns.

Mmechi

Redispersible polymer ntụ ntụ bụ ụdị polymer ntụ ntụ nwere ike redispersed na mmiri na-etolite a kwụsiri ike emulsion. A na-eji ya eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu dị ka ihe mgbakwunye iji melite arụmọrụ nke ihe ndị dabeere na ciment. Usoro mmepụta nke RDP gụnyere ọtụtụ usoro, gụnyere nhọrọ polymer, nkwadebe ngwọta, atomization, ihicha, na igwe igwe. Ogo nke ngwaahịa ikpeazụ na-adabere na ịdị mma nke akụrụngwa na usoro usoro eji eme ihe n'oge mmepụta.
