Lisebelisoa tse tala tsa phofo ea Latex e Hasoang hape

Redispersed latex powder (RDP) ke mofuta oa phofo ea polymer emulsion e sebelisoang haholo indastering ea kaho bakeng sa lits'ebetso tse kang li-adhesives tse entsoeng ka samente, metsoako ea ho itšehla thajana, le lisebelisoa tsa ka ntle le lisebelisoa tsa ho qetela. Li-RDP li entsoe ka ho fafatsa emulsion ea polymer, e leng motsoako oa metsi, monoma kapa motsoako oa li-monomers, surfactant, le li-additives tse fapaneng. Sehloohong sena, re tla tšohla lisebelisoa tse tala tse sebelisoang hangata ho hlahisa li-RDP.

1. Li-monomers Li-monomers tse sebelisoang tlhahisong ea li-RDP li ka fapana ho ea ka thepa e lakatsehang ea sehlahisoa sa ho qetela. Li-monomers tse sebelisoang ka tloaelo li kenyelletsa styrene, butadiene, acrylic acid, methacrylic acid, le tse tsoang ho tsona. Rabara ea styrene-butadiene (SBR) ke khetho e tsebahalang bakeng sa li-RDP ka lebaka la ho khomarela hantle, ho hanyetsa metsi, le ho tšoarella nako e telele.
2. Li-surfactants li sebelisoa tlhahisong ea li-RDPs ho tsitsisa emulsion le ho thibela coagulation kapa flocculation. Li-surfactants tse tloaelehileng tse sebelisoang ho li-RDP li kenyelletsa li-anionic, cationic, le li-surfactants tsa nonionic. Li-surfactants tsa anionic ke mofuta o sebelisoang ka ho fetisisa ho li-RDP, kaha li fana ka botsitso bo botle ba emulsion le ho lumellana le lisebelisoa tsa cementitious.
3. Li-stabilizers li sebelisoa ho thibela likaroloana tsa polymer ka har'a emulsion ho tloha ho kopanya kapa ho bokellana nakong ea polokelo le lipalangoang. Li-stabilizer tse tloaelehileng tse sebelisoang ho li-RDP li kenyelletsa joala ba polyvinyl (PVA), hydroxyethyl cellulose (HEC), le carboxymethyl cellulose (CMC).
4. Li-Initiator Initiators li sebelisoa ho qala karabelo ea polymerization lipakeng tsa li-monomers ka har'a emulsion. Li-initiator tse tloaelehileng tse sebelisoang ho li-RDP li kenyelletsa li-initiators tsa redox, tse kang potassium persulfate le sodium bisulfite, le li-initiators tsa mocheso, tse kang azobisisobutyronitrile.
5. Li-neutralizing agents li sebelisetsoa ho fetola pH ea emulsion ho ea boemong bo loketseng bakeng sa polymerization le botsitso. Lisebelisoa tse tloaelehileng tse sebelisoang ho RDPs li kenyelletsa ammonia, sodium hydroxide, le potasiamo hydroxide.
6. Li-Crosslinking agents li sebelisoa ho tšela liketane tsa polymer ho emulsion, e ka ntlafatsang thepa ea mochini le ho hanyetsa metsi a sehlahisoa sa ho qetela. Lisebelisoa tse tloaelehileng tse sebelisoang ho RDPs li kenyelletsa formaldehyde, melamine, le urea.
7. Plasticizers Plasticizers e sebelisoa ho ntlafatsa ho tenyetseha le ho sebetsa ha RDPs. Li-plasticizers tse tloaelehileng tse sebelisoang ho RDPs li kenyelletsa polyethylene glycol (PEG) le glycerol.
8. Li-Fillers Filler li eketsoa ho li-RDP ho ntlafatsa thepa ea bona ea mochini le ho fokotsa litšenyehelo. Li-filler tse tloaelehileng tse sebelisoang ho li-RDP li kenyelletsa calcium carbonate, talc, le silica.
9. Li-Pigments Pigments li eketsoa ho li-RDP ho fana ka mebala le ho ntlafatsa botle ba sehlahisoa sa ho qetela. Li-pigments tse tloaelehileng tse sebelisoang ho RDPs li kenyelletsa titanium dioxide le iron oxide.

Qetellong, lisebelisoa tse tala tse sebelisoang tlhahisong ea li-RDP li ka fapana ho latela thepa e lakatsehang ea sehlahisoa sa ho qetela. Li-monomers, surfactants, stabilizers, initiator, neutralizing agents, crosslinking agents, plasticizers, fillers, le pigments kaofela li sebelisoa ka tloaelo tlhahiso ea RDPs.
