Ho hlahisa mekotla ea polyer e rekiloeng ke mokhoa o rarahaneng o kenyelletsang mekhahlelo e mengata, e 'ngoe le e' ngoe ea bohlokoa ho fihlela thepa le ts'ebetso ea ho qetela.
1. Selelekela bakeng sa phofo ea polymer polyer phofo
A. Tlhaloso le ts'ebeliso
Lipofo tsa polyer tse khutlisoang ke likokoana-hloko tsa polymer tse ka hasana habonolo metsing ho etsa emupi tse tsitsitseng. Makhoakhoa ana a sebelisoa haholo lisebelisoa tsa kaho, lidhesions, lidhems ha li ntse li ntlafatsa thepa ea mochini, ho sesa le ho feto-fetoha ha lihlahisoa tsena.
B. Motsoako oa mantlha
Metsoako e ka sehloohong ea Polymer ea polymer e kenyellelitsoeng:
Plymer Binder: Motsoako oa polymer ke karolo ea mantlha mme hangata ke copolymer of vinysa acetate kapa ea e loketseng Polymer. Sena se fana ka maemo a ho feto-fetoha le maemo a ho qetela le ho latela.
Khokahano ea Tsamaiso: Kenya likhakanyo kapa li-colloids tse sireletsang ho thibela likaroloana tsa polymer ho tloha botsitso nakong ea polokelo.
LITLHAKISO: Likjekello tse fapaneng, tse kang ho nyahama, tse ling, masesele, le lithibela, li ka kenyeletsa ho matlafatsa thepa e itseng ea phofo.
2. Ts'ebetso ea Tlhahiso
A. Emulsion polymerization
Khetho ea menomer: Mohato oa pele o kenyelletsa ho khetha basomi ba bohlokoa bakeng sa karabelo ea polymeriation, hangata e le Vinyl Acytate le Ethylene.
Emalfish: U sebelisa li-surfactant ho tlola masole a mafura ho theha emulusi e tsitsitseng.
Polymeriation: Qalong e eketsoa ho emulsion ho qala karabelo ea polymeriation. Metsotso ea polymer e hola 'me qetellong e etsa bilymer binder.
Mehato ea Boitšoaro: Mehato e Meng e kang ho laola PH le mocheso li bohlokoa ho fihlela thepa ea polymer eo u e batlang ea polymer.
B. Spray o omileng
Ho tsepamisa mohopolo: Ho tsepamisa mohopolo omumu ea polymer ho se anngoeng se lekanang se loketseng ho omella.
Fofa ho omella: emulsion e tsitsitseng e atile ka phapusing e meholo ea monko o omisang. Metsi a fetoha mouoane, a siea likaroloana tse tiileng tsa polymer.
Taolo ea boholo ba Karolelano: "Fokotsa liparame tse fapaneng ho kenyelletsa tekanyo ea lijo, mocheso le moralo oa nozzle ho laola boholo ba phofo e hlahisoang.
C. Powder Post-Post-Ts'ebetso
Ho eketsa lithupelo tse sireletsang: Mekhoa e sirelletsang hangata e kenyelletsa matla ho thibela karohano ea mokokotlo ebe u ntlafatsa ho eketseha.
Likhalase tse ling: Li-adtive tse ling li ka hlahisoa sethaleng sena ho matlafatsa thepa e tobileng ea phofo.
3. Taolo ea Boleng le Teko
A. Tlhahlobo ea boholo ba boholo
Tekanyetso ea Laser: Mekhoa ea tloaelo ea laser ea laser e tloaetse ho lekanya kabo ea boholo ba karoloana ea polyer.
Microscopy: Ho ka hlahlojoa puo ea microscoppic
B. Tlhahlobo ea Boitsebiso
Teko ea ho nchafatsa Metsi: Kopanya phofo ka metsi ho lekola bokhoni ba ho theha emululu e tsitsitseng.
Tlhahlobo e bona: Lekola ponahalo ea phofo e kentsoeng, ho kenyelletsa le li-clumps kapa liagglomerate.
C. Tlhahlobo ea lik'hemik'hale
Polymer Compution: Mekhoa e kang ea Trier Transforffer Spectrascopy (FTIR) li sebelisetsoa ho sekaseka sebopeho sa lik'hemik'hale sa polymer.
SEHLOOHO MOTANE MONTHOTR: Sebelisa li-chromatography tsa khase kapa mekhoa e meng ho fumana ho ba teng ha masome a setseng.
4 .. Liphephetso le Mehopolo
A. Tšitiso ea tikoloho
Khetho ea lintho tse bonahalang: Ho khetha bakuli ba tikoloho le thepa e tala ho ka fokotsa tšusumetso ea tikoloho ea ts'ebetso ea ho etsa thepa.
Matla arder: Ho phethela ts'ebeliso ea matla ethalong ea ho omisa ho omisa mehla, e etsa hore ho be le matla.
B. Ts'ebetso ea sehlahisoa
Polymer Commetion: Khetho ea polymer le sebopeho sa eona e ama haholo thepa ea polyer ea polyer e khutlisehang.
Ho nepahala ha ho boloka: Ho eketsa li-kgolohi tse sirelelitsoeng tse loketseng ho bohlokoa ho thibela phofo e tšetsoeng nakong ea polokelo.
Liphetho
Ho etsa lits'ila tsa Polyer tsa Proporching ho kenyelletsa motsoako o rarahaneng oa Emulsion Poulymerization, e fafatsa mehato ea ho omisa le ea poso. Mehato ea taolo ea boleng, ho kenyelletsa tlhahlobo ea boholo ba karohano le tlhahlobo ea ho khutlisa, li bohlokoa ho netefatsa hore sehlahisoa se lumellana le litlhaloso. Ho leka-lekanya sebaka sa tikoloho le ho leka-kenana le ho lekanyelitsoeng.
