Inqubo yokukhiqiza ye-polymer powder evuselelayo

Inqubo yokukhiqiza ye-polymer powder (RPP) ifaka izigaba eziningana, kufaka phakathi i-polymerization, ukomisa okufafaza, nokusebenza ngemuva. Nakhu ukubuka konke kwenqubo ejwayelekile yokukhiqiza:

1. I-Polymerization:

Inqubo iqala nge-polymerization yama-monomer ukukhiqiza ukuhlakazeka okuzinzile kwe-polymer noma i-emulsion. Ukukhethwa kwama-monomers kuncike kwizakhiwo ezifiselekayo kanye nokusetshenziswa kwe-RPP. Ama-monomers ajwayelekile afaka i-vinyl acetate, ethylene, i-butyl acrylate, no-methyl methacrylate.

1. Ukulungiselela Monomer: AmaMonomers ahlanzwa futhi ahlanganiswa namanzi, abaQamanga, kanye nezinye izengezo esitsheni sokuphendula.
2. I-Polymerization: Ingxube ye-monomer iqhubekela phambili kwe-polymerization ngaphansi kokushisa okulawulwayo, ingcindezi, kanye nezimo zokuphazamiseka. Abaqambi baqala ukusabela kwe-polymerization, okuholela ekwakhiweni kwamaketanga we-polymer.
3. Ukuzinza: Ama-surfactants noma ama-emulsifiers angezwa ukuqinisa ukusabalalisa kwe-polymer futhi avikele ukuhlangana noma ukuhlangana kwama-polymer.

2. Spray COMSE:

Ngemuva kwe-polymerization, ukuhlakazeka kwe-polymer kufakwa ngaphansi komiswa ukuwuguqula kube yifomu elomile kafulawa. Ukuchomisa okufafaza kufaka phakathi ukusabalalisa ukuhlakazeka kube amaconsi amahle, asuswe emfuleni oshisayo womoya.

1. I-Atomization: Ukuhlakazwa kwe-polymer kubhejwa i-nozzle yokufafaza, lapho ingena khona ngamaconsi amancane asebenzisa umoya ocindezelwe noma i-athomizer ye-centrifugal.
2. Drying: The droplets are introduced into a drying chamber, where they come into contact with hot air (usually heated to temperatures between 150°C to 250°C). Ukuhanjiswa kwamanzi ngokushesha okuvela kumaconsi kuholela ekwakhekeni kwezinhlayiya eziqinile.
3. Ukuqoqwa kwezinhlayiya: Izinhlayiya ezomile ziqoqwa egumbini lokumisa zisebenzisa izivunguvungu noma izihlungi zesikhwama. Izinhlayiya ezinhle zingahle zihlukaniswe ukususa izinhlayiya eziqine futhi ziqinisekise ukusatshalaliswa kosayizi abafanayo.

3. I-Post-Iyacubungula:

Ngemuva kokomiswa kwesifutho, i-RPP ithola izinyathelo zokusebenza ngemuva kokuthuthukisa izakhiwo zayo futhi iqinisekise ukuqina komkhiqizo.

1. Ukupholisa: I-RPP eyomile ipholile ekushiseni kwegumbi ukuvikela ukumuncwa umswakama futhi kuqinisekiswe ukuzinza komkhiqizo.
2. Ukupakishwa: I-RPP epholile ifakwe kwizikhwama ezivimbela umswakama noma iziqukathi zokuyivikela kusuka kumswakama nasemswakama.
3. Ukulawulwa kwekhwalithi: I-RPP ithola ukuhlolwa kwekhwalithi yekhwalithi ukuqinisekisa izakhiwo zayo zomzimba neyomakhemikhali, kufaka phakathi usayizi wezinhlayiyana, ubungako obuningi, okuqukethwe okusele komswakama, okuqukethwe okuyisisekelo komswakama, okuqukethwe kwe-polymer.
4. Isitoreji: I-RPP ehlanganisiwe igcinwa endaweni elawulwayo ukuze ikwazi ukuqina nokuphila kweshelufu kuze kuthunyelwe kumakhasimende.

Isiphetho:

Inqubo yokukhiqiza ye-polymer powder evuselelayo ifaka ama-polymerization ama-monomer ukukhiqiza ukuhlakazeka kwe-polymer, kulandelwe ukomisa isifutho ukuguqula isimo sefomu elomile. Izinyathelo zokufaka ukucubungula ziqinisekisa ikhwalithi yomkhiqizo, ukuqina, kanye nokupakisha ukugcinwa nokusatshalaliswa. Le nqubo inika amandla ukukhiqizwa kwama-RPPs aguquguqukayo kanye nama-RPPs asetshenzisiwe ezimbonini ezahlukahlukene, kufaka phakathi ukwakhiwa, ukupenda kanye nokumboza, ukunamathela kanye nezindwangu.
