Amagqabantshintshi ngomgubo wepolymer oDispersible

I-re-dispersible polymer powder (RDP) luhlobo lwe-polymer material olusetyenziswa ngokubanzi kwishishini lokwakha. Ingumgubo omhlophe okanye omhlophe owenziwe nge-spray-drying polymer emulsions. Umgubo obangelwayo unokuxutywa ngokulula namanzi ukwenza ukumiswa okuzinzileyo okungasetyenziswa njenge-binder, i-adhesive, okanye i-coating.

I-RDPs isetyenziswa ngokuqhelekileyo kwiintlobo ezininzi zezicelo zokwakha, kubandakanywa i-tile adhesives, i-grouts, i-self-leveling compounds, kunye ne-insulation yangaphandle kunye neenkqubo zokugqiba (EIFS). Zikwasetyenziswa xa kuveliswa udaka oluxubeneyo olomileyo, oluyimixube yesamente, isanti, nezinye izinto ezisetyenziselwa ukwenza ikhonkrithi, udaka nezinye izinto zokwakha.

Iipropati ze-RDP zinokwahluka ngokuxhomekeke kuhlobo oluthile lwepolymer esetyenzisiweyo, kunye nenkqubo yokuvelisa. Nangona kunjalo, ngokubanzi, ii-RDPs zinezi mpawu zilandelayo:

1. Amandla aphezulu okubopha: I-RDPs inokwenza izibophelelo ezinamandla kunye neentlobo ezahlukeneyo ze-substrates, kubandakanywa ikhonkrithi, ukhuni kunye nesinyithi.

2. Ukumelana namanzi: Ii-RDPs zixhathisa kakhulu emanzini, okwenza ukuba zilungele ukusetyenziswa kwiindawo ezimanzi.

3. Ukuguquguquka: Ii-RDPs zinokuqulunqwa ukuba ziguquguquke, ezivumela ukuba zikwazi ukumelana noxinzelelo kunye nokunyakaza ngaphandle kokuqhekeka okanye ukuphuka.

4. Ukusebenza kakuhle: Ii-RDPs zinokuxutywa ngokulula namanzi ukwenza intlama egudileyo, esebenzayo okanye ukumiswa.

5. Ukubambelela kakuhle: I-RDPs inokubophelela kakuhle kwiintlobo ezahlukeneyo ze-substrates, kubandakanywa iindawo ezinqabileyo kunye nezingekho.

6. Ukumelana neekhemikhali ezilungileyo: Ii-RDPs zixhathisa kakhulu kwiikhemikhali ezininzi, kuquka i-acids, iziseko kunye nezinyibilikisi.

Kukho iintlobo ngeentlobo zee-RDP ezifumanekayo kwimarike, nganye ineempawu zayo ezizodwa kunye neempawu zayo. Ezinye zezona ntlobo zixhaphakileyo ziquka:

1. I-ethylene-vinyl acetate (EVA) copolymers: Ezi RDPs ziguquguquka kakhulu kwaye zinamathele ngokugqwesileyo kuluhlu olubanzi lwee-substrates. Ngokuqhelekileyo zisetyenziselwa ukunamathiswa kweetayile, i-grouts, kunye ne-EIFS.

2. I-Vinyl acetate-ethylene (VAE) copolymers: Ezi RDPs ziyakwazi ukumelana namanzi kwaye zinamathele kakuhle kwiintlobo ezahlukeneyo ze-substrates. Ngokuqhelekileyo zisetyenziselwa ukugquma kwangaphandle kunye neenkqubo zokugqiba (EIFS), kunye ne-adhesives tile kunye ne-grouts.

3. I-Styrene-butadiene (SB) copolymers: Ezi RDPs ziguquguquka kakhulu kwaye zinamathele ngokugqwesileyo kwiintlobo ezahlukeneyo ze-substrates. Ngokuqhelekileyo zisetyenziselwa ukunamathiswa kweetayile, i-grouts, kunye ne-EIFS.

4. I-Acrylics: Ezi RDPs ziyakwazi ukumelana namanzi kwaye zinamathele kakuhle kwiintlobo ezahlukeneyo ze-substrates. Ngokuqhelekileyo zisetyenziselwa ukugquma kwangaphandle kunye neenkqubo zokugqiba (EIFS), kunye ne-adhesives tile kunye ne-grouts.

5. I-Polyvinyl alcohol (PVA): Ezi RDP zi-soluble kakhulu emanzini kwaye zinamathele kakuhle kwiintlobo ezahlukeneyo ze-substrates. Ngokuqhelekileyo zisetyenziselwa umxube owomileyo kunye ne-binder kwiingubo zephepha.

Ukongeza ekusebenziseni kwabo kushishino lokwakha, ii-RDPs zikwasetyenziswa kwiintlobo ngeentlobo zezinye izicelo, ezibandakanya:

1. Iingubo zokwaleka: Ii-RDPs zinokusetyenziswa njengengubo yokwaleka amalaphu ukuphucula ukuxhathisa kwamanzi kunye nokuqina.

2. Iipeyinti kunye neengubo: I-RDPs ingasetyenziswa njenge-binder kwiipende kunye neengubo zokuphucula ukubambelela kunye nokuxhathisa kwamanzi.

3. I-Adhesives: I-RDPs ingasetyenziselwa njenge-binder kwi-adhesives ukuphucula amandla abo kunye nokuchasana kwamanzi.

4. Iimveliso zokunyamekela: Ii-RDPs zingasetyenziselwa kwiimveliso zokunyamekela komntu, njengeegels zeenwele kunye ne-skin creams, ukuphucula ukuthungwa nokuzinza kwazo.

Ngokubanzi, iipolymer powders eziphinda zihlakazwe ziyinto eguquguqukayo kwaye ibalulekileyo kushishino lokwakha nangaphaya. Ngeempawu zabo ezizodwa kunye noluhlu olubanzi lwezicelo, baqinisekile ukuba baya kuqhubeka nokudlala indima ebalulekileyo kumashishini amaninzi kwiminyaka ezayo.
