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 otu monomers na-agụnye 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 ịgbasa n'ime 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.
