Likarolo tsa phofo ea emulsion e qhalanngoang hape ke life?
Phofo ea Emulsion e Nchafalitsoeng (RDP) ke motsoako o rarahaneng oa likarolo tse 'maloa, e' ngoe le e 'ngoe e tlatsetsa ts'ebetsong le ts'ebetsong ea eona. Leha mekhoa e ka fapana ho latela moetsi ea itseng le ts'ebeliso e reriloeng, likarolo tse tloaelehileng tsa RDP li kenyelletsa:
1.Sehokelo sa Polymer: Karolo e ka sehloohong ea RDP ke sehokelo sa polymer, seo hangata se nkiloeng ho vinyl acetate ethylene (VAE), vinyl acetate versatate (VeoVA), ethylene vinyl chloride (EVC), kapa li-copolymer tse ling. Sehokelo sena sa polymer se fana ka thepa ea sekhomaretsi 'me se etsa filimi e kopaneng ha e oma.
2.Colloid e Sireletsang: Ho tsitsisa emulsion le ho thibela ho kopana kapa ho phaphamala ha dikarolwana tsa polymer, ho eketsoa colloid e sireletsang. Di-colloid tse sireletsang tse tlwaelehileng di kenyeletsa di-ether tsa cellulose (mohlala, hydroxyethyl cellulose, methyl cellulose), polyvinyl alcohol (PVA), le di-derivatives tsa starch.
3.Lisebelisoa tsa polasetiki: Li-plasticizer li kenyelelitsoe ho ntlafatsa ho tenyetseha le ho sebetsa ha filimi ea RDP. Li thusa ho fokotsa ho robeha le ho ntlafatsa ho khomarela, haholo-holo mefuteng e tsamaisoang ke motsamao kapa ho fetoha ha sebopeho.
4.Li-filler: Li-filler tse sa pheleng tse kang calcium carbonate, talc, silica, kapa letsopa li ka eketsoa mefuteng ea RDP ho ntlafatsa bongata ba lintho tse ngata, ho fokotsa litšenyehelo le ho fetola litšobotsi tsa mechini. Li-filler li boetse li thusa ho laola rheology le ho ntlafatsa litšobotsi tsa ts'ebeliso ea lipente le li-mortar.
5.Li-defoamer: Ho kenyelelitsoe disebediswa tse silafatsang letlalo ho fokotsa ho thehwa ha foam nakong ya tlhahiso le tshebediso ya RDP. Foam e feteletseng e ka ama hampe tshebetso le ponahalo ya dikobo le dikhomaretsi.
6.Li-stabilizer: Li-stabilizer li sebelisoa ho boloka botsitso ba emulsion le ho thibela karohano ea mekhahlelo kapa ho kopana ha likaroloana tsa polymer. Li thusa ho netefatsa ts'ebetso e tsitsitseng le botsitso ba polokelo ea lihlahisoa tsa RDP.
7.Baemeli ba ho qhalanya: Disebediswa tse hasanyang di thusa ho hasanyeng ha dikarolwana tsa RDP ka metsing, di kgothaletsa kabo e tshwanang le ho thibela ho kopana ha tsona. Di ntlafatsa ho qhalana ha phofo ya RDP ditsamaisong tsa metsi, di thusa ho kenngwa ha tsona ka hara dihlahiswa.
8.Lisebelisoa tsa ho Thibela ho Hatsela: Maemong a batang kapa nakong ea polokelo maemong a batang a mocheso o tlase, lintho tse thibelang ho hoama li ka eketsoa ho thibela ho hoama le ho boloka botsitso ba li-emulsion tsa RDP.
9.Likokoana-hloko: Li-biocide li ka kenyelletsoa ho thibela kholo ea likokoana-hloko le ho atolosa bophelo ba lihlahisoa tsa RDP, haholo-holo mefuteng e kotsing ea ho silafatsoa.
10.Lisebelisoa tse ling: Ho latela ditlhoko tse ikgethang tsa tshebediso e rerilweng, di-additives tse ding tse kang di-thickeners, dispersants, di-crosslinking agents, le di-film-forming helps di ka kenyeletswa mefuteng ya RDP ho etsa hore thepa ya tsona le dibopeho tsa tshebetso di tshwane.
Ka kakaretso, khetho e hlokolosi le tekano ea likarolo tsena li bapala karolo ea bohlokoa ho khethoeng ha ts'ebetso, botsitso le ho tenyetseha ha Redispersible Emulsion Powder lits'ebetsong tse fapaneng tsa kaho le ho koahela.
