Ungayibona kanjani kahle i-polymer powder (RDP)

I-Redispersible polymer powder (RDP) iyisengezo se-polymer esisetshenziswa kabanzi esiguqule umkhakha wezinto zokwakha. Ibambe iqhaza elikhulu ekuthuthukiseni ikhwalithi nokuqina kwezinto ezihlukahlukene zokwakha. Nokho, ukuhlonza i-RDP kungase kube nzima, ikakhulukazi kulabo abangazazi izici zayo.

Nawa amanye amathiphu okuthi ungayibona kanjani i-RDP ngendlela efanele:

1. Ukwakheka kwamakhemikhali

I-RDP iyi-copolymer ye-vinyl acetate ne-ethylene. I-polymerized kusuka ku-vinyl acetate, i-ethylene namanye ama-monomers phambi kwama-surfactants nama-colloid avikelayo. Ukwakheka kwamakhemikhali e-RDP kudlala indima ebalulekile ekusebenzeni nasekuziphatheni kwayo. Ngakho-ke, kubalulekile ukufunda ukwakheka kwamakhemikhali e-RDP ngaphambi kokuyisebenzisa ezintweni zokwakha.

2. Izici

I-RDP inezici ezithile ezibonakala kalula. Okokuqala, iyimpushana emhlophe, emhlophe noma ekhanyayo ephuzi. Okwesibili, inobubanzi bezinhlayiyana zama-microns angu-5-100. Okwesithathu, iyancibilika emanzini futhi inezinto ezinhle zokunamathela.

3. Ukupakisha

I-RDP ivamise ukupakishwa esikhwameni sepulasitiki esivaliwe noma esitsheni ukuze kuvinjelwe ukumuncwa komswakama. Ngokuvamile kuba nelebula nekhodi ephaketheni elihlinzeka ngolwazi mayelana nohlobo, ibanga nomkhiqizi we-RDP. Kubalulekile ukuhlola ukupakishwa ngaphambi kokuthenga i-RDP ukuze uqiniseke ukuthi ayiphazanyiswanga noma ayivezwanga emswakameni.

4. Izici zokusebenza

I-RDP ibonisa izici zokusebenza ezimbalwa eziyehlukanisa kwamanye ama-polymer. Isibonelo, i-RDP inokumelana kahle namanzi, ukunamathela okuhle kakhulu kanye nokuguquguquka. Iphinde ibe nezakhiwo ezinhle zokwenza ifilimu, okuyenza ibe isithasiselo esifanele sezinto zokwakha ezifana nokunamathiswa kwamathayela, i-grout, nokhonkolo.

5. Ukuvumelana

I-RDP iyahambisana nezinye izinto zokwakha ezifana nosimende, igypsum kanye nomcako. Ukuhambisana kwayo nalezi zinto kuqinisekisa ukuthi ukusebenza komkhiqizo wokugcina akukona. Ngakho-ke, kubalulekile ukuhlola ukuhambisana kwe-RDP ngaphambi kokuyisebenzisa ezintweni zokwakha.

Kafushane, ukuhlonza i-RDP kudinga ukuqonda okuyisisekelo kokwakheka kwamakhemikhali, izici, ukupakishwa, ukusebenza, nokuhambisana. Ngokugxila kulezi zici, umuntu angakwazi ukuhlukanisa kalula i-RDP kwamanye ama-polymers futhi aqinisekise ukusetshenziswa kwayo okufanele ezintweni zokwakha.
