Redispersible latex powder ke phofo e fumanoang ka ho omisa emulsion ea polymer ebe e eketsa lintho tse fetotsoeng, tse ka fetisoang hape ho etsa emulsion ha e kopana le metsi. Redispersible latex powder e sebelisoa haholo-holo e le tlatsetso bakeng sa seretse se omeletseng, se nang le mesebetsi ea ho ntlafatsa ts'ebetso ea seretse, ho ntlafatsa metsi, ho ntlafatsa momahano, le ho eketsa matla a ho kopanya. Ke mofuta o mocha oa thepa e baballang tikoloho. Hajoale, phofo ea latex e hloka ho eketsoa ho tlamahano ea lithaele, ho kenella ka ntle ho lebota, ho ikemela, phofo ea putty, joalo-joalo ho ntlafatsa bonding le sag resistance ea seretse.
Emulsion ea polymer e sebelisoang ka boteng ba latex phofo ke haholo-holo emulsion ea polymer e entsoeng ka ho eketsa monomers e le 'ngoe kapa tse peli ho vinyl acetate e le monoma Chaena. Hona joale, vinyl acetate-ethylene copolymer emulsion, vinyl acetate - Haholo-holo ethylene tertiary carbonate copolymer emulsion, li-additives li tla kenngoa ho phofo ea latex e hlahisoang ho ntlafatsa anti-caking le redispersibility. Leha ho le joalo, ka lebaka la sebopeho sa vinyl acetate, matla a eona a pele le matla a ho folisa metsi ha a ntle mabapi le ho khomarela mapolanka a ho kenya letsoho le li-substrates tsa samente.
Acrylic emulsion e na le khanyetso e ntle ea metsi 'me e sebelisoa haholo indastering ea thepa ea mohaho, empa mokhoa oa eona oa ho omisa ka ho toba le oa ho fafatsa phofo ha oa hōla,' me karolo ea eona ka redispersible emulsion phofo e nyenyane haholo, 'me ho khomarela ha acrylic emulsion ho futsanehile,' me ho joalo. e khomaretseng seretse. Ntlafatso e sa lekaneng ea matla a tlamahano e fokotsa tšebeliso ea li-emulsion tsa acrylic.
Sepheo sa novel acrylic latex powder le mokhoa oa ho lokisa ke ho fumana lihlahisoa tsa latex powder tse nang le matla a holimo a kopantsoeng le ho khomarela hantle.
1. Phofo ea latex e redispersible e na le momahano o babatsehang, o ka ntlafatsang momahano oa seretse sa mohaho, ho ntlafatsa ho khomarela pakeng tsa seretse le lisebelisoa tsa motheo, le ho ntlafatsa ho sebetsa. E loketse lisebelisoa tsa mohaho le liretse tse hlokang matla a holimo a tlamahano. tšimo, tebello ea 'maraka e pharaletseng.
2. Tsamaisong ea tlhahiso ea phofo ea latex e redispersible, mefuta e fapaneng ea emulsion ea polymer e thehiloeng ho emulsion ea acrylic e khethiloe 'me e kopantsoe ho ea ka karo-karolelano e loketseng, e ka fanang ka papali e feletseng ho melemo ea bona, ho ntlafatsa ts'ebetso ea phofo ea latex, le eketsa bophara ba phofo ea latex. bophara ba kopo.
3. Ha ho lokisoa phofo ea latex e ka sebelisoang hape, mokelikeli oa spray o futhumetse ka ho toba ka ho futhumatsa ka marang-rang, e leng ho ntlafatsang ho tsosolosoa ha phofo ea latex.
4. Ka mokhoa o hlophisitsoeng oa phofo ea morao-rao ea morao-rao, mefuta e 'meli ea metsoako ea calcium carbonate, phofo ea talcum, kaolin le silicon dioxide e khethoa e le li-anti-caking agents tse nang le karolelano ea boima ba 1: 1-2, e le hore phofo ea latex. likaroloana Ho phuthela ho tšoana haholo 'me thepa ea anti-caking ea phofo ea latex e ntlafatsoa.
5. Ka mokhoa oa ho hlophisoa ha phofo ea latex e redispersible, e le 'ngoe kapa motsoako oa silicone defoamer le oli ea diminerale defoamer e khethoa e le defoamer ka tekanyo ea boima ba 1: 1, e ntlafatsang Thepa ea ho etsa filimi ea phofo ea latex. e ntlafatsa matla a maqhama a seretse.
6. Mokhoa oa ho itokisa oa phofo ea latex e redispersible e bonolo ebile e bonolo ho hlokomela indasteri.
