Redispersible polymer powder (RDP) sisongezo sepolymer esisetyenziswa ngokubanzi esiguqule intsimi yezinto zokwakha. Idlale indima ebalulekileyo ekuphuculeni umgangatho kunye nokuqina kwezinto ezahlukeneyo zokwakha. Nangona kunjalo, ukuchonga i-RDP kunokuba nzima kancinci, ngakumbi kwabo bangaqhelananga neempawu zayo.
Nanga amanye amacebiso ngendlela yokuchonga ngokufanelekileyo iRDP:
1. Ukuqulunqwa kweekhemikhali
I-RDP yi-copolymer ye-vinyl acetate kunye ne-ethylene. I-polymerized ukusuka kwi-vinyl acetate, i-ethylene kunye nezinye ii-monomers phambi kwee-surfactants kunye ne-colloids ezikhuselayo. Ukwakhiwa kweekhemikhali zeRDP kudlala indima ebalulekileyo ekusebenzeni nasekuziphatheni kwayo. Ke ngoko, kubalulekile ukufunda imichiza ye-RDP ngaphambi kokuyisebenzisa kwizinto zokwakha.
2. Iimpawu
I-RDP ineempawu ezithile ezibonakala lula. Okokuqala, ngumgubo omhlophe ocolekileyo, ongekho mhlophe okanye okhanyayo otyheli. Okwesibini, inoluhlu lwesayizi ye-5-100 microns. Okwesithathu, iyanyibilika emanzini kwaye ineempawu ezintle zokuncamathelisa.
3. Ukupakishwa
I-RDP idla ngokupakishwa kwingxowa yeplastiki etywiniweyo okanye isikhongozeli ukunqanda ukufunxa ukufuma. Ngokuqhelekileyo kukho ileyibhile kunye nekhowudi kwiphakheji enika ulwazi malunga nohlobo, ibakala kunye nomvelisi we-RDP. Kubalulekile ukuhlola ukupakishwa phambi kokuthenga i-RDP ukuqinisekisa ukuba ayiphazanyiswanga okanye ayivezwanga kukufuma.
4. Iimpawu zokusebenza
I-RDP ibonisa iimpawu ezininzi zokusebenza eziyahlula kwezinye iipholima. Umzekelo, i-RDP inokuxhathisa okulungileyo kwamanzi, ukunamathela okugqwesileyo kunye nokuguquguquka. Ikwanazo neempawu ezintle zokwenza ifilim, nto leyo eyenza ukuba ibe sisongezo esifanelekileyo sezinto zokwakha ezifana nokunamathelisa iithayile, igrout, kunye nekhonkrithi.
5. Ukuhambelana
I-RDP iyahambelana nezinye izixhobo zokwakha ezifana nesamente, igypsum kunye nekalika. Ukuhambelana kwayo nezi zinto kuqinisekisa ukuba ukusebenza kwemveliso yokugqibela ayiphazamiseki. Ke ngoko, kubalulekile ukuvavanya ukuhambelana kwe-RDP ngaphambi kokuba uyisebenzise kwizinto zokwakha.
Isishwankathelo, ukuchonga i-RDP kufuna ukuqonda okusisiseko kokwakheka kweekhemikhali, iipropathi, ukupakishwa, ukusebenza, kunye nokuhambelana. Ngokugxininisa kule miba, umntu unokwahlula ngokulula i-RDP kwezinye iipolymers kwaye aqinisekise ukusetyenziswa kwayo ngokufanelekileyo kwizinto zokwakha.
