Ts'ebetso ea Tlhahiso ea Phofo ea Polymer e Nchafalitsoeng

Ts'ebetso ea tlhahiso ea phofo ea polymer e qhalakanngoang hape (RPP) e kenyelletsa mekhahlelo e 'maloa, ho kenyeletsoa le ho etsa polymerization, ho omisa ka spray, le ho sebetsana le eona ka mor'a ts'ebetso. Mona ke kakaretso ea ts'ebetso e tloaelehileng ea tlhahiso:

1. Ho etsa hore e be polymer:

Ts'ebetso e qala ka ho polymerisa ha li-monomer ho hlahisa ho hasana ha polymer ho tsitsitseng kapa emulsion. Khetho ea li-monomer e itšetlehile ka thepa e lakatsehang le ts'ebeliso ea RPP. Li-monomer tse tloaelehileng li kenyelletsa vinyl acetate, ethylene, butyl acrylate, le methyl methacrylate.

1. Tokisetso ea Monomer: Li-monomer lia hloekisoa 'me li kopanngoa le metsi, li-initiator le lintho tse ling tse ekelitsoeng ka har'a sejana sa reactor.
2. Ho etsa hore lintho li be polymer: Motsoako oa monomer o feta ho etsa hore lintho li be polymer tlas'a maemo a laoloang a mocheso, khatello le ho sisinyeha. Ba qalang ba qala karabelo ea ho etsa lintho li be polymer, e leng se lebisang ho thehoeng ha liketane tsa polymer.
3. Ho Tsitsisa: Li-surfactant kapa li-emulsifier lia eketsoa ho tsitsisa ho hasana ha polymer le ho thibela ho hoama kapa ho kopana ha likaroloana tsa polymer.

2. Ho omisa ka Spray:

Kamora ho etsa polymerization, ho hasana ha polymer ho omisoa ka spray ho e fetola mofuta wa phofo e omileng. Ho omisa ka spray ho kenyelletsa ho etsa atomization ya ho hasana hore e be marothodi a manyane, ao ebe a omiswa ka hara molapo o chesang wa moya.

1. Atomization: Ho hasana ha polymer ho pompeloa ho ea nozzle ea spray, moo e atomized ho ba marotholi a manyane ho sebelisoa moea o hatelletsoeng kapa atomizer ea centrifugal.
2. Ho omisa: Marotholi a kenngoa ka phaposing ea ho omisa, moo a kopanang le moea o chesang (hangata o futhumatsoa ho fihlela mochesong o pakeng tsa 150°C le 250°C). Ho mouoane ka potlako ha metsi a tsoang marotholing ho lebisa ho thehoeng ha likaroloana tse tiileng.
3. Pokello ea Likaroloana: Likaroloana tse omisitsoeng li bokelloa ka phapusing ea ho omisa ho sebelisoa lifefo kapa li-filter tsa mekotla. Likaroloana tse tšesaane li ka 'na tsa hlophisoa ka lihlopha tse ling ho tlosa likaroloana tse kholo le ho netefatsa hore boholo ba likaroloana boa lekana.

3. Kamora ho Sebetsa:

Kamora ho omisa ka spray, RPP e feta mehatong ya kamora ho sebetsa ho ntlafatsa thepa ya yona le ho netefatsa botsitso ba sehlahiswa.

1. Ho Pholisa: RPP e omisitsoeng e phodiswa mochesong wa kamore ho thibela ho monyela mongobo le ho netefatsa botsitso ba sehlahiswa.
2. Pakete: RPP e phodisitsweng e kentswe ka hara mekotla kapa dijana tse hanelang mongobo ho e sireletsa mongobong le mongobong.
3. Taolo ea Boleng: RPP e feta litekong tsa taolo ea boleng ho netefatsa thepa ea eona ea 'mele le ea lik'hemik'hale, ho kenyeletsoa boholo ba likaroloana, bongata ba bongata, mongobo o setseng, le litaba tsa polymer.
4. Polokelo: RPP e phuthetsweng e bolokwa tikolohong e laolwang ho boloka botsitso ba yona le nako ya ho e boloka e le teng ho fihlela e romelwa ho bareki.

Qetello:

Ts'ebetso ea tlhahiso ea phofo ea polymer e qhalakantsoeng hape e kenyelletsa ho polymerization ea li-monomers ho hlahisa ho hasana ha polymer, ho lateloa ke ho omisa ka spray ho fetola ho hasana hore e be foromo ea phofo e omileng. Mehato ea kamora ts'ebetso e netefatsa boleng ba sehlahisoa, botsitso le sephutheloana bakeng sa polokelo le kabo. Ts'ebetso ena e nolofalletsa tlhahiso ea li-RPP tse feto-fetohang le tse sebetsang ka bongata tse sebelisoang liindastering tse fapaneng, ho kenyeletsoa kaho, pente le lipente, likhomaretsi le masela.
