Zithini izinto ezisetyenziswa kwi-emulsion powder ephinda inyibilike?

I-Redispersible Emulsion Powder (RDP) ngumxube ontsonkothileyo wezinto ezininzi, nganye inegalelo ekusebenzeni kwayo kunye nokusebenza kwayo. Nangona iifomyula zinokwahluka ngokuxhomekeke kumenzi othile kunye nesicelo esicwangcisiweyo, izinto eziqhelekileyo ze-RDP ziquka:

1.Isibopheleli sePolymer: Inxalenye ephambili ye-RDP yi-polymer binder, edla ngokuvela kwi-vinyl acetate ethylene (VAE), i-vinyl acetate versatate (VeoVA), i-ethylene vinyl chloride (EVC), okanye ezinye ii-copolymers. Le polymer binder inika iipropati zokuncamathelisa kwaye yenza ifilimu edibeneyo xa yomile.

2.I-Colloid ekhuselayo: Ukuze kuzinziswe i-emulsion kwaye kuthintelwe ukujiya okanye ukuxinana kwamasuntswana e-polymer, kongezwa i-colloid ekhuselayo. Ii-colloid ezikhuselayo eziqhelekileyo ziquka ii-cellulose ethers (umz., i-hydroxyethyl cellulose, i-methyl cellulose), i-polyvinyl alcohol (PVA), kunye ne-starch derivatives.

3.Izinto zokucoca: Iiplastiki zifakelwe ukuphucula ukuguquguquka nokusebenza kakuhle kwefilimu ye-RDP. Zinceda ekunciphiseni ukuqhekeka kunye nokuphucula ukunamathela, ingakumbi kwiifomyula ezishukumayo okanye eziguquguqukayo.

4.Izizalisi: Izithambisi ezingezizo zendalo ezifana ne-calcium carbonate, i-talc, i-silica, okanye udongwe zingongezwa kwi-RDP formulations ukuphucula uxinano olukhulu, ukunciphisa iindleko, kunye nokutshintsha iimpawu zoomatshini. Izithambisi zikwanceda ukulawula i-rheology kunye nokuphucula iimpawu zokusetyenziswa kweengubo kunye neemortar.

5.Izinto zokuthambisa i-defoam: Iiarhente zokungcolisa i-foam ziyabandakanywa ukunciphisa ukwakheka kwe-foam ngexesha lokuveliswa nokusetyenziswa kwe-RDP. I-foam egqithisileyo inokuchaphazela kakubi ukusebenza kunye nokubonakala kwe-coating kunye ne-adhesives.

6.Izinto zokuzinzisa: Izibambisi-ndlela zisetyenziselwa ukugcina uzinzo lwe-emulsion kunye nokuthintela ukwahlukana kwesigaba okanye ukuhlangana kwamasuntswana e-polymer. Zinceda ukuqinisekisa ukusebenza okuzinzileyo kunye nozinzo lokugcina lweemveliso ze-RDP.

7.Iiarhente zokusasaza: Ii-arhente zokusasazeka zinceda ekusasazekeni kwee-RDP particles emanzini, zikhuthaza ukusasazwa okufanayo kwaye zithintele ukuhlangana. Ziyandisa ukusasazeka kwakhona kwee-RDP powders kwiinkqubo zamanzi, zinceda ukufakwa kwazo kwiifomyula.

8.Izinto zokungaqandisi: Kwimozulu ebandayo okanye ngexesha lokugcina kumaqondo obushushu aphantsi, ii-antifreeze agents zingongezwa ukuthintela ukubanda nokugcina uzinzo lwee-RDP emulsions.

9.Izinto ezibangela iintsholongwane: Ii-biocides zingafakwa ukuthintela ukukhula kweentsholongwane kunye nokwandisa ubomi beshelufu yeemveliso ze-RDP, ingakumbi kwiifomyula ezisengozini yongcoliseko.

10.Ezinye izongezo: Ngokuxhomekeke kwiimfuno ezithile zesicelo esicetywayo, izongezo ezongezelelweyo ezifana nezithina, izisasazi, ii-agents ezidibanisayo, kunye nezixhobo zokwenza ifilimu zinokufakwa kwi-RDP formulations ukuze zilungelelanise iipropati zazo kunye neempawu zokusebenza.

Lilonke, ukukhethwa ngononophelo kunye nokulinganisela kwezi zinto kudlala indima ebalulekileyo ekumiseleni ukusebenza, uzinzo, kunye nokuguquguquka kweRedispersible Emulsion Powder kwiindlela ezahlukeneyo zokwakha kunye nokufaka i-coating.
