Usoro mmepụta nke ntụ ntụ Polymer Redispersible

Usoro mmepụta nke ntụ ntụ Polymer Redispersible

Usoro mmepụta nke redispersible polymer powder (RPP) gụnyere ọtụtụ usoro, gụnyere polymerization, ịgba ihicha, na nhazi nhazi. Nke a bụ nkọwapụta nke usoro mmepụta a na-ahụkarị:

1. Polymerization:

Usoro ahụ na-amalite site na polymerization nke monomers iji mepụta mgbasa ma ọ bụ emulsion polymer kwụsiri ike. Nhọrọ nke monomers dabere na ihe ndị a chọrọ na ngwa nke RPP. Ndị monomers a na-ahụkarị gụnyere vinyl acetate, ethylene, butyl acrylate, na methyl methacrylate.

  1. Nkwadebe monomer: A na-asachapụ monomers ma gwakọta ya na mmiri, ihe mmalite, na ihe mgbakwunye ndị ọzọ n'ime ụgbọ mmiri reactor.
  2. Polymerization: Ngwakọta monomer na-enweta polymerization n'okpuru ọnọdụ okpomọkụ a na-achịkwa, nrụgide, na ọnọdụ mkpali. Ndị mbido na-ebute mmeghachi omume polymerization, na-eduga n'ichebe ụdọ polymer.
  3. Nkwụsi ike: A na-agbakwunye surfactants ma ọ bụ emulsifiers iji mee ka mgbasawanye polymer kwụsie ike ma gbochie coagulation ma ọ bụ agglomeration nke mkpụrụ ndụ polymer.

2. ịgbasa nkụ:

Mgbe polymerization, na polymer dispersion na-doro ịgba ihicha iji tọghata ya n'ime a akọrọ ntụ ntụ ụdị. Ịkpọsa ihe fesa na-agụnye ịgbasasị na-agbasasị n'ime obere ụmụ irighiri mmiri dị mma, nke a na-akpọnwụ na mmiri na-ekpo ọkụ.

  1. Atọmịka: A na-ebufe ihe na-agbasa polymer n'ime oghere ịgba, ebe a na-etinye ya n'ime obere ụmụ irighiri mmiri na-eji ikuku abịakọrọ ma ọ bụ atomizer centrifugal.
  2. Ịkpọ nkụ: A na-ewebata ụmụ irighiri mmiri ndị ahụ n'ime ụlọ ihicha, ebe ha na-abanye na ikuku ọkụ (na-ekpo ọkụ na-ekpo ọkụ n'etiti 150 ° C ruo 250 ° C). Ngwa ngwa evaporation nke mmiri sitere na ụmụ irighiri mmiri na-eduga n'ịmepụta ihe siri ike.
  3. Mkpokọta urughuru: A na-anakọta ihe ndị a mịrị amị site n'ọnụ ụlọ ihicha site na iji cyclones ma ọ bụ nzacha akpa. Ezi ahụ nwere ike ịga n'ihu nhazi ọkwa iji wepụ ihe karịrị irighiri irighiri ma hụ na nkesa nha nha nha nha.

3. Nhazi mgbe emechara:

Mgbe ihichapụ ịgbasa, RPP na-enweta usoro nhazi post-processing iji melite akụrụngwa ya ma hụ na nkwụsi ike ngwaahịa.

  1. Ntu oyi: A na-eme ka RPP a mịrị amị mee ka ọ dị jụụ n'ime ụlọ iji gbochie mmịpụta mmiri ma hụ na nkwụsi ike ngwaahịa.
  2. Nkwakọ ngwaahịa: A na-etinye RPP jụrụ oyi n'ime akpa ma ọ bụ arịa na-eguzogide mmiri iji chebe ya pụọ ​​​​na mmiri na iru mmiri.
  3. Njikwa ogo: RPP na-enweta ule njikwa mma iji nyochaa njirimara anụ ahụ na kemịkal ya, gụnyere nha urughuru, njupụta buru ibu, ọdịnaya mmiri fọdụrụ na ọdịnaya polymer.
  4. Nchekwa: A na-echekwa RPP ngwugwu na ebe a na-achịkwa iji nọgide na-enwe nkwụsi ike na ndụ ndụ ruo mgbe a na-ebuga ya na ndị ahịa.

Mmechi:

Usoro mmepụta nke redispersible polymer ntụ ntụ na-agụnye polymerization nke monomers na-emepụta a polima dispersion, sochiri ịgba ihicha iji tọghata dispersion n'ime a akọrọ ntụ ntụ ụdị. Usoro nhazi mgbe emechara hụ na ịdịmma ngwaahịa, nkwụsi ike, na nkwakọ ngwaahịa maka nchekwa na nkesa. Usoro a na-enyere aka ịmepụta RPP dị iche iche na multifunctional eji na ụlọ ọrụ dị iche iche, gụnyere ihe owuwu, agba na mkpuchi, adhesives, na textiles.
