Ibikoresho bibisi bya pisitori ya Latex yagaruwe

Ifu ya redispersed latex (RDP) ni ubwoko bwifu ya polymer emulsion ikoreshwa cyane mubikorwa byubwubatsi kugirango ikoreshwe nka sima ishingiye kuri sima, ibyuma byishyira hamwe, hamwe na sisitemu yo hanze ndetse na sisitemu yo kurangiza. RDPs ikorwa no gutera spray yumye polymer emuliyoni, ikaba ari uruvange rwamazi, monomer cyangwa imvange ya monomers, surfactant, ninyongeramusaruro zitandukanye. Muri iki kiganiro, tuzaganira ku bikoresho fatizo bikoreshwa mu gutanga RDPs.

1. Monomers Monomers ikoreshwa mugukora RDPs irashobora gutandukana bitewe nibintu byifuzwa byibicuruzwa byanyuma. Monomers ikunze gukoreshwa harimo styrene, butadiene, aside acrylic, aside methacrylic, nibiyikomokaho. Ribber ya Styrene-butadiene (SBR) ni amahitamo akunzwe kuri RDPs kubera kuyifata neza, kurwanya amazi, no kuramba.
2. Surfactants Surfactants ikoreshwa mugukora RDPs kugirango ihagarike emulisiyo kandi irinde coagulation cyangwa flocculation. Ibikoresho bisanzwe bikoreshwa muri RDPs birimo anionic, cationic, na nonionic surfactants. Anionic surfactants nubwoko bukoreshwa cyane muri RDPs, kuko zitanga emulsiyo nziza ihamye kandi igahuzwa nibikoresho bya sima.
3. Stabilisateur Stabilisateur ikoreshwa mukurinda ibice bya polymer muri emulsiya guhuriza hamwe cyangwa guteranya mugihe cyo kubika no gutwara. Stabilisateur zikoreshwa muri RDP zirimo inzoga za polyvinyl (PVA), hydroxyethyl selulose (HEC), na carboxymethyl selulose (CMC).
4. Initiators Initiators ikoreshwa mugutangiza polymerisation reaction hagati ya monomers muri emulsion. Abatangizi basanzwe bakoreshwa muri RDPs barimo abatangiza redox, nka potasiyumu persulfate na sodium bisulfite, hamwe nabatangiza ubushyuhe, nka azobisisobutyronitrile.
5. Ibikoresho bidafite aho bibogamiye bikoreshwa muguhindura pH ya emulsiyo kurwego rukwiye rwa polymerisation no gutuza. Ibikoresho bisanzwe bitesha agaciro bikoreshwa muri RDPs birimo ammonia, hydroxide ya sodium, na hydroxide ya potasiyumu.
6. Ibikoresho byambukiranya imiti ikoreshwa muguhuza iminyururu ya polymer muri emulsion, ishobora kunoza imiterere yubukanishi hamwe n’amazi yo kurwanya ibicuruzwa byanyuma. Ibikoresho bisanzwe bihuza bikoreshwa muri RDPs harimo fordehide, melamine, na urea.
7. Amashanyarazi akoreshwa mu kunoza imikorere n'imikorere ya RDPs. Amashanyarazi asanzwe akoreshwa muri RDPs arimo polyethylene glycol (PEG) na glycerol.
8. Abuzuza buzuza bongerewe muri RDP kugirango batezimbere imashini zabo kandi bagabanye ibiciro. Ibisanzwe byuzuzwa bikoreshwa muri RDP birimo calcium karubone, talc, na silika.
9. Pigment Pigment yongewe kuri RDPs kugirango itange ibara kandi itezimbere ubwiza bwibicuruzwa byanyuma. Ibisanzwe bisanzwe bikoreshwa muri RDPs birimo dioxyde ya titanium na okiside ya fer.

Mu gusoza, ibikoresho fatizo bikoreshwa mugukora RDPs birashobora gutandukana bitewe nibintu byifuzwa byibicuruzwa byanyuma. Monomers, surfactants, stabilisateur, abitangiza, ibintu bitagira aho bibogamiye, ibintu bihuza, plasitike, ibyuzuza, hamwe na pigment byose bikoreshwa mugukora RDPs.
