I-Polymer Modifiers

Ama-polymer modifiers yizinto ezengezwa kuma-polymers ukuze kuthuthukiswe ukusebenza kwazo noma ukunikeza izakhiwo ezintsha. Kunezinhlobo ezahlukahlukene zama-polymer modifiers, kufaka phakathi ama-filler, ama-plasticizers, ama-crosslinking agents, nama-diluent asebenzayo, phakathi kokunye. Olunye uhlobo lwesilungisi se-polymer oluvame ukusetshenziswa ezintweni zokwakha i-Redispersible Polymer Powder (RDP).

I-Redispersible Polymer Powder (RDP) iwuhlobo lwesilungisi se-polymer esisetshenziswa ezintweni zokwakha ezifana nezisimende zikasimende, izinto zokunamathisela zamathayela, nezinhlanganisela ezizilinganisa. Yenziwa ngokufafaza-omiswe ingxube ye-polymer emulsion kanye ne-colloid evikelayo, futhi ngokuvamile isekelwe ku-vinyl acetate-ethylene (VAE) noma i-ethylene-vinyl acetate (EVA) copolymers.

I-RDP iyimpushana emhlophe, egeleza mahhala engaphinde ihlakazwe kalula emanzini. Uma ixubene namanzi nezinto zikasimende, yenza ifilimu ezinzile, eguquguqukayo, futhi ehlala njalo ethuthukisa izakhiwo zezinto zokwakha. Ezinye zezinzuzo zokusebenzisa i-RDP njengesilungisi se-polymer zifaka:

1. Ukusebenza okuthuthukisiwe: I-RDP ithuthukisa ukusebenza kahle kwezinto zikasimende ngokunciphisa okuqukethwe kwamanzi kanye nokwenza ngcono i-rheology. Lokhu kubangela ukunamathela okungcono, ukuphatha kalula, nokuncipha kokuqhekeka.
2. Amandla akhulayo: I-RDP ithuthukisa amandla nokuqina kwezinto zikasimende ngokwandisa amandla ebhondi kanye nokunciphisa ukungakwazi ukungena. Lokhu kubangela into yokwakha enamandla futhi ehlala isikhathi eside.
3. Ukumelana kangcono namanzi namakhemikhali: I-RDP ithuthukisa ukumelana nezinto zikasimende emanzini namakhemikhali ngokunciphisa ukubola kanye nokwenza ngcono ukungagxili. Lokhu kubangela into yokwakha engangeni manzi futhi imelana namakhemikhali.
4. Ukunamathela okungcono: I-RDP ithuthukisa ukunamathela kwezinto zikasimende kuma-substrates ahlukahlukene, okuhlanganisa ukhonkolo, amatshe, nokhuni. Lokhu kubangela isibopho esiqinile futhi esihlala isikhathi eside phakathi kwezinto zokwakha kanye ne-substrate.

I-RDP isetshenziswa ezintweni zokwakha ezahlukahlukene, kufaka phakathi:

1. Izisimende ezisasimende: I-RDP isetshenziswa odakeni lukasimende olufana nokunamathiswa kwamathayela, ama-grouts, nama-renders. Ithuthukisa ukusebenza, amandla, nokuqina kwalezi zinto zokusebenza, okuholela ekuqedeni okungcono nempilo ende.
2. Izinhlanganisela zokuzilinganisa: I-RDP isetshenziswa kumakhompiyutha azilinganisa ukuze kuthuthukiswe ukugeleza kwawo kanye nezakhiwo zokuleveling. Iphinde ithuthukise amandla abo nokuqina, okuholela ekuqedeni okungcono.
3. Imikhiqizo esekwe kwi-Gypsum: I-RDP isetshenziswa emikhiqizweni eyenziwe nge-gypsum efana nezinhlanganisela ezihlangene kanye namapulasi. Ithuthukisa ukusebenza, amandla, nokuqina kwale mikhiqizo, okuholela ekuqedeni okushelelayo nempilo ende.
4. Izinto zokuvikela: I-RDP isetshenziswa ezintweni zokuvikela ezifana nodaka olushisayo kanye nezingubo zokugqoka. Ithuthukisa ukunamathela, amandla, nokuqina kwalezi zinto zokwenziwa, okuholela ekwandeni okungcono nokuhlala isikhathi eside.

Sengiphetha, i-Redispersible Polymer Powder (RDP) iwuhlobo lwesilungisi se-polymer esivame ukusetshenziswa ezintweni zokwakha ukuze kuthuthukiswe izakhiwo zazo. Ithuthukisa ukusebenza, amandla, nokuqina kwezinto zikasimende, okuholela ekuqedeni okungcono nempilo ende. I-RDP isetshenziswa ezintweni zokwakha ezahlukahlukene ezifana nezisimende zikasimende, izinhlanganisela ezizilinganisa, kanye nemikhiqizo eyenziwe nge-gypsum, phakathi kokunye.
