Izinto Eziluhlaza Zempushana Ye-latex Ehlakazekile Kabusha

I-latex powder ehlanjululwe kabusha (RDP) iwuhlobo lwe-polymer emulsion powder olusetshenziswa kakhulu embonini yezokwakha ukuze kufakwe izicelo ezifana nokunamathiswa kwamathayela asekelwe kusimende, izinhlanganisela zokuzilinganisa, kanye ne-insulation yangaphandle kanye nezinhlelo zokuqeda. Ama-RDP enziwa ngokufafaza okomisa i-polymer emulsion, eyingxube yamanzi, i-monomer noma ingxube yama-monomers, i-surfactant, nezithasiselo ezihlukahlukene. Kulesi sihloko, sizoxoxa ngezinto zokusetshenziswa ezivame ukusetshenziselwa ukukhiqiza ama-RDP.

1. Ama-Monomers Ama-monomer asetshenziswa ekukhiqizeni ama-RDP angahluka kuye ngezici ezifiselekayo zomkhiqizo wokugcina. Ama-monomers avame ukusetshenziswa afaka i-styrene, i-butadiene, i-acrylic acid, i-methacrylic acid, kanye nokuphuma kwayo. Irabha ye-styrene-butadiene (SBR) iyinketho ethandwayo yama-RDP ngenxa yokunamathela kwayo okuhle, ukumelana namanzi, nokuqina.
2. Ama-surfactants Ama-surfactants asetshenziswa ekukhiqizeni ama-RDP ukuze kunzinziswe i-emulsion nokuvimbela ukuhlangana noma ukugoqa. Ama-surfactants avamile asetshenziswa kuma-RDP afaka ama-anionic, cationic, nama-nonionic surfactants. Ama-Anionic surfactants awuhlobo olusetshenziswa kakhulu kuma-RDP, njengoba ehlinzeka ngokuzinza okuhle kwe-emulsion nokuhambisana nezinto zikasimende.
3. Ama-Stabilizers Ama-Stabilizer asetshenziselwa ukuvimbela izinhlayiya ze-polymer ku-emulsion kusukela ekuhlanganiseni noma ukuhlanganisa ngesikhathi sokugcina nokuhamba. Iziqinisi ezijwayelekile ezisetshenziswa kuma-RDP zifaka i-polyvinyl alcohol (PVA), i-hydroxyethyl cellulose (HEC), ne-carboxymethyl cellulose (CMC).
4. Ama-initiators Ama-initiators asetshenziselwa ukuqalisa ukusabela kwe-polymerization phakathi kwama-monomers ku-emulsion. Iziqalisi ezivamile ezisetshenziswa kuma-RDP zihlanganisa iziqalisi ze-redox, ezifana ne-potassium persulfate ne-sodium bisulfite, neziqalisi ezishisayo, njenge-azobisisobutyronitrile.
5. Ama-Neutralizing agents asetshenziselwa ukulungisa i-pH ye-emulsion ibe sezingeni elifanele le-polymerization nokuzinza. Ama-ejenti avamile wokungathathi hlangothi asetshenziswa kuma-RDP ahlanganisa i-ammonia, i-sodium hydroxide, ne-potassium hydroxide.
6. Ama-Crosslinking agents asetshenziselwa ukunqamula amaketanga e-polymer ku-emulsion, engathuthukisa izakhiwo zemishini kanye nokumelana namanzi komkhiqizo wokugcina. Ama-ejenti ajwayelekile okuxhumanisa asetshenziswa kuma-RDP afaka i-formaldehyde, i-melamine, ne-urea.
7. Ama-Plasticizers Ama-Plasticizer asetshenziselwa ukuthuthukisa ukuguquguquka nokusebenza kwama-RDP. Amapulasitiki avamile asetshenziswa kuma-RDP ahlanganisa i-polyethylene glycol (PEG) ne-glycerol.
8. Ama-Fillers Fillers ayengezwa kuma-RDPs ukuthuthukisa izakhiwo zawo zemishini nokunciphisa izindleko. Izigcwalisi ezijwayelekile ezisetshenziswa kuma-RDP zifaka i-calcium carbonate, i-talc, ne-silica.
9. Ama-Pigments Pigments anezelwa kuma-RDP ukuze anikeze umbala futhi athuthukise ubuhle bomkhiqizo wokugcina. Izingulube ezivamile ezisetshenziswa kuma-RDP zihlanganisa i-titanium dioxide ne-iron oxide.

Sengiphetha, izinto zokusetshenziswa ezisetshenziswa ekukhiqizeni ama-RDP zingahluka kuye ngezici ezifiselekayo zomkhiqizo wokugcina. Ama-monomers, ama-surfactants, ama-stabilizer, ama-initiators, ama-ajenti ahlukanisayo, ama-crosslinking agents, ama-plasticizer, ama-filler, nama-pigments konke kuvame ukusetshenziswa ekukhiqizeni ama-RDP.
