2. Tokisetso ea Emulsion
KHETHA LITLHAKISO TSE KHOLO TSE TSOANG HO MABAPITSA HO PAYMETEGE ACT PHARA PELYMER ENMLSON EMPRES E NANG LE LITLHAKISO TSE KHOLO. Nakong ea ho hlophisoa ha emulsion, mehato e latelang ea bohlokoa e lokela ho hlokometsoe:
Khetho ea Monotor le kakaretso: Khetha Mosomimers e loketseng, Vinyl Acetate, joalo ka sepheo sa bona ho netefatsa hore ts'ebetso ea emulsion.
Emulsion Poulymerization: Hangata e lokoloha polymerization ea methapo e sebelisetsoang ho qobella batho ba bangata hore ba kene lesapo la polymer. Tsela ea polymeria e hloka ho etsoa tlasa maemo a laoletsoeng ka thata, ho kenyelletsa le lebelo, le susumetsang ka lebelo, sekhahla sa pelehi, jj.
Ho eketsoa ha koluoa e sireletsang le setaele: Kenya li-colloid tse sireletsang tse sirelelitsoeng le ho hlonepha ho thibela emulsion nakong ea ho omisa ho latela nako eo u e palameng.
3. Pretloa ea Emulsion
Pele ho omella, emulsion e hloka ho etsoa, haholo-holo mehato e latelang:
Ho fitlisetsa litšila: Tlosa litšila ho emulsion ka filthara kapa centrifuge ho netefatsa bohloeki ba emulsion.
Tsepamisa maikutlo: Shebella emulsion ho li-sekhele tse loketseng ka ho fetoha mouoane kapa membrane ea moea ho ntlafatsa ts'ebetso e omileng.
4. Spray o omileng
Ho omella ke ts'ebetso ea mantlha bakeng sa ho etsa phofo ea morao-rao ea morao. Mehato e ikhethileng e tjena:
Khetho ea Tora ea Flip e forahang: Khetha lisebelisoa tse nepahetseng tsa ho omisa ho latela thepa le litlolo tsa emulsion. Sesebelisoa se sebelisoang hangata se kenyelletsa tora ea sengoatho le khatello ea khatello ea khatello ea khatello ea maikutlo.
Ho lupa ha lijalo tsa moea tse ommeng: Beha mocheso o loketseng oa moea, mocheso oa moea le ho fafatsa khatello. Ka kakaretso, mocheso oa moea oa kokoana-hloko o laoloa ka 150-200 ℃, mocheso oa moea o ahle o laoloa ho 60-80 ℃.
E fafatsa ts'ebetso ea ho omella: Emulsion e netefalitsoeng e amana marotholi a matle ka moea o chesang, 'me metsi a mouoane ho theha likaroloana tse ntle tse omileng.
Pokello ea Power: Phokotso ea Latax e amiloeng e bokelloa ke karohano ea letsopa kapa filimi ea mokotla. Polao e bokelletsoeng ea mor'a ho phuthoa e hloka ho foka le likokoana-hloko tse kholo li tlosoa ka ho hlahlobisisa sehlahisoa.
5. Ts'ebetso ea poso le ho paka
Polao e omisitsoeng ea morao-rao e hloka ho sebetsoa hantle ho netefatsa ts'ebetso ea eona e tsitsitseng le polokelo e bolokehileng. Ho sebetsa ka poso ho kenyelletsa:
Phekolo ea Anti-Caking: Kenya li-agents tsa Anti-Caking (joalo ka phofo ea phofo, silicon dioxide) ho thibela phofo ho thibela phofo le ho tsamaisa thepa le lipalangoang.
Ho paka: Ho latela litlhoko tsa bareki, phofo ea bonex e kenella bopaking ba mongobo le mekotla ea masene kapa lireswana. Mongobo o hloka ho laoloa ka kotloloho nakong ea pakete ho thibela phofo ho tsoa ho ho amohela mongobo.
6. Taolo ea boleng
Nakong ea tlhahiso ea tlhahiso, taolo ea boleng bo matla e hlokahala ho netefatsa hore matšoao a ts'ebetso ea phofo ea morao-rao ea Polax ea morao-rao e fihlela litlhoko. Lintho tse tloaelehileng tsa taolo ea boleng ba boleng bo akaretsang:
Tsamaiso ea boholo ba eona
Matla a khomarela: Leka matla a khomarela phofo e fapaneng ka lehlakoreng le fapaneng ho netefatsa ts'ebetso ea eona ea ho ikarola.
Ho itšireletsa: Kopanya phofo ea latex e nang le metsi ho boloka hore na e ka hasana ka matla le ho khutlisetsoa haholo.
7. Sesebelisoa le Litlhokomelo
Polao ea Lamelax e rekiloeng e sebelisoa haholo ho hahoang kertar, lidolara tsa polasetiki, lerako le sililoeng le masimo a mang. Lintlha tse latelang li hloka ho tsejoa ha u sebelisa:
Maemo a polokelo: Polao ea Latex e lokela ho bolokoa tikolohong e omileng le e pholileng ho qoba mocheso le mongobo o phahameng.
Tekanyetso ea ts'ebeliso: ho latela litlhokahalo tse khethehileng tsa ts'ebeliso, eketsa phofo ea morao-rao ho fumana ts'ebetso e ntle ka ho fetisisa.
Ka litlatsetso tse ling: Ho fokotsa phofo ea latex hangata ho sebelisoa le litlatsetso tse ling (tse kang cellulose ether, Defoamer) ho ntlafatsa ts'ebetso ea thepa eo.
Ho khutlisoa phofo ea latex e nang le ts'ebetso e ntle e ka etsoa ka katleho. Ho tlhahiso ea 'nete, ho hlokahala hore u tloaelane le maemo a tlhahiso le litlhokahalo tsa sehlahisoa ho netefatsa boleng bo tsitsitseng le bo tšepahalang ba sehlahisoa sa ho qetela.
