Inkqubo yeMveliso yePolymer Powder eDispersible

Inkqubo yokuvelisa i-polymer powder ehlaziywayo (RPP) ibandakanya izigaba ezininzi, kubandakanywa i-polymerization, i-spray drying, kunye ne-post-processing. Nantsi isishwankathelo senkqubo yemveliso eqhelekileyo:

1. Ukwenziwa kwePolymerization:

Inkqubo iqala nge-polymerization ye-monomers ukuvelisa i-polymer dispersion okanye i-emulsion ezinzileyo. Ukukhethwa kweemonomers kuxhomekeke kwiipropati ezifunwayo kunye nokusetyenziswa kwe-RPP. Iimonomers eziqhelekileyo ziquka i-vinyl acetate, i-ethylene, i-butyl acrylate, kunye ne-methyl methacrylate.

1. Ukulungiswa kwe-Monomer: I-Monomers iyahlanjululwa kwaye ixutywe namanzi, abaqalisi, kunye nezinye izongezo kwisitya se-reactor.
2. I-Polymerization: Umxube we-monomer wenziwa i-polymerization phantsi kobushushu obulawulwayo, uxinzelelo, kunye neemeko zokuphazamiseka. Abaqalisi baqalisa i-polymerization reaction, ekhokelela ekwakhiweni kwamakhonkco e-polymer.
3. Uzinziso: Ii-surfactants okanye i-emulsifiers zongezwa ukuzinzisa ukusasazwa kwepolymer kunye nokuthintela ukuhlangana okanye ukudityaniswa kwamasuntswana epolymer.

2. Ukutshiza ukomisa:

Emva kwepolymerization, i-polymer dispersion iphantsi komiswe ngokutshiza ukuyiguqula ibe yifomu eyomileyo yomgubo. Ukomisa ukutshiza kubandakanya ukusasazwa ngeathomu ibe ngamathontsi acolekileyo, athi emva koko omiswe kumlambo oshushu.

1. I-Atomization: I-polymer dispersion impontshelwa kumbhobho wokutshiza, apho ithi i-atom ibe ngamathontsi amancinci kusetyenziswa umoya ocinezelweyo okanye i-atomizer ephakathi.
2. Ukomisa: Amathontsi angeniswa kwindawo yokomisa, apho adibana nomoya oshushu (udla ngokufudunyezwa kumaqondo obushushu aphakathi kwe-150°C ukuya kuma-250°C). Ukunyuka ngokukhawuleza kwamanzi kumathontsi kukhokelela ekubunjweni kwamasuntswana aqinileyo.
3. Ukuqokelelwa kweNqaku: Amasuntswana omisiweyo aqokelelwa kwigumbi lokomisa kusetyenziswa iinkanyamba okanye izihluzi zengxowa. Amasuntswana amahle anokuthi aqhubeke nokwahlulwa ukuze asuse amasuntswana amakhulu kwaye aqinisekise ukuhanjiswa kobungakanani bamasuntswana afanayo.

3. Emva kokulungiswa:

Emva kokumisa ukutshiza, i-RPP ithatha amanyathelo emva kokulungiswa kokuphucula iimpawu zayo kunye nokuqinisekisa ukuzinza kwemveliso.

1. Ukupholisa: I-RPP eyomileyo ipholile kwiqondo lokushisa kwegumbi ukukhusela ukufunxa ukufuma kunye nokuqinisekisa ukuzinza kwemveliso.
2. Ukupakishwa: I-RPP epholileyo ipakishwe kwiingxowa okanye kwizikhongozeli ezinganyangekiyo ukufuma ukufuma nokufuma.
3. Ukulawulwa komgangatho: I-RPP ivavanywa ngokulawulwa komgangatho ukuze iqinisekise iimpawu zayo zomzimba kunye neekhemikhali, kubandakanya ubungakanani bamasuntswana, ukuxinana kobuninzi, ukufuma okushiyekileyo, kunye nomxholo wepolymer.
4. Ukugcinwa: I-RPP epakishweyo igcinwe kwindawo elawulwayo ukuze igcine uzinzo kunye nobomi beshelufu ide ithunyelwe kubathengi.

Isiphelo:

Inkqubo yokuvelisa i-polymer powder edispersible ibandakanya i-polymerization ye-monomers ukuvelisa i-polymer dispersion, ilandelwa ngokumisa ukutshiza ukuguqula ukusasazeka kwifom eyomileyo. Amanyathelo okuthunyelwa emva kokuqinisekisa umgangatho wemveliso, ukuzinza, kunye nokupakishwa kokugcinwa kunye nokuhanjiswa. Le nkqubo yenza ukuba ukwenziwa kwee-RPP eziguquguqukayo nezisebenzayo ezisetyenziswa kumashishini ahlukeneyo, kubandakanywa ulwakhiwo, iipeyinti kunye nezaleko, izinto zokuncamathelisa, kunye namalaphu.
