Yini ukusetshenziswa kwe-polymer powder evuselelayo (RDP)?

I-Redisperible Powmer Powder (RDP) iyimpuphu ehlukahlukene ye-polymer esetshenziswa ezinhlobonhlobo zezimboni kanye nezicelo. Kuyimpuphu emhlophe egeleza mahhala equkethe i-polymer emulsion kanye izengezo ezingashintshwa kalula emanzini ukuze kwakhiwe ama-emulsions azinzile. Izakhiwo ezihlukile ze-RDP zenza kube yizinto eziguquguqukayo ezinezicelo zokwakha, ezinamathela, ezinamathela, upende kanye nezinye izimboni.

Izakhiwo ze-polymer powder (RDP)

Ukwakheka kwe-polymer:

I-RDP iqukethe ngokuyinhloko ingxube ye-polymer emulsion. Lawa ma-polymers angafaka phakathi i-vinyl acetate-ethylene (VAE), i-vinyl acetate-acrylic acid copolymers, nokunye okunjalo.
Ukukhetha ukwakheka kwe-polymer kuthinta izici zokusebenza kwe-RDP, njengokunamathela, ukuguquguquka nokumelana namanzi.

Ubukhulu bezinhlayiyana ne-morphology:

Ama-polymer polymer polymer ajwayele ukuba nosayizi omuhle wezinhlayiyana, okunomthelela emandleni awo okwenza ama-emulsions azinzile lapho ahlelwe emanzini.
I-morphology yezinhlayiya yenzelwe ukukhuthaza ukuhamba okuhle futhi ithuthukise izakhiwo zokuhlakazwa ze-powder.

Izithasiselo zamakhemikhali:

Izithasiselo ezahlukahlukene, ezinjengezinto ezihlakazekile, ama-anti-caking agents, nama-colloids avikelayo, avame ukungezwa ukwenza ngcono ukuqina nokuphathwa kwe-powder.

ukulupheka:

I-RDP iyahambelana nezinye izinto zokwakha ezahlukahlukene, kufaka phakathi usimende, udaka kanye nabasizi, okwenza izicelo ezahlukahlukene.
Inqubo Yokukhiqiza Yama-PolyMer POWDERS
Ukukhiqizwa kwama-polymer powders abukeli kuhilela izinyathelo ezimbalwa ezibalulekile:

Emulsion polymerization:

Inqubo iqala nge-emulsion polymerization yama-monomer afana ne-vinyl acetate, ethylene, nezinye izimomonomo.
Ama-emulsifiers kanye nokuqiniswa asetshenziselwa ukuqinisekisa ukwakheka kwama-emulshonts ezinzile.

Ukufafaza ukomisa:

I-polymer emulsion isebhekwe kwinqubo yokuchomisa yokufafaza, esusa amanzi ukuze akhe izinhlayiya eziqinile.
I-powder ephumayo iqoqwe futhi iqhutshwe futhi ukuthola usayizi oyifisayo wezinhlayiya kanye ne-morphology.
Ukufakwa okungeziwe:

Izithasiselo zamakhemikhali ezinjengabalwa ama-anti-casiking agents kanye nabasakazi bangezwa ku-powder ukuze bathuthukise isitoreji sabo kanye nokuphatha izici.

QC:

Izindlela eziqinile zokulawula ikhwalithi ziyasetshenziswa ukuqinisekisa ukuvumelana nokusebenza komkhiqizo wokugcina we-polymer powder.

Izicelo ze-polymer powder (RDP)
1. Imboni yezokwakha:
Ama-tile anamathela: I-RDP ithuthukisa ukunamathela, ukuguquguquka nokumelana kwamanzi kwama-tile anamathela, kuthuthukisa ukusebenza okuphelele nokuqina kokufakwa kwakho kwethayela.
Usimende ngodaka Kubuye kunciphise ukuqhekeka futhi kwandisa ukuguquguquka kodaka.

2. Ukufakwa kwangaphandle kanye nezinhlelo zokuqeda (ama-EIF):
I-EIFS isebenzisa i-RDP ukuthuthukisa ukuguquguquka kohlelo nokumelana nokuqhekeka, ukunikeza isiphetho esihlala isikhathi eside futhi esijabulisayo.

I-3. Amakhompiyutha wokuzimela:
Ezindaweni ezihlanganisiwe zokuzimela, i-RDP isiza ukuthuthukisa ukugeleza, ukunamathela kanye nokuvimbela ukuqhekeka.

4. Imikhiqizo ye-Gypsum:
I-RDP isetshenziswa emikhiqizweni esekwe ku-gypsum efana ne-compain ehlanganisiwe ne-stucco ukuthuthukisa ukunamathela kwabo, ukusebenziseka kanye nokumelana nokuqhekeka.

I-5
Embonini we-Paint and Coatings, i-RDP isetshenziselwa ukuthuthukisa ukunamathela, ukuguquguquka nokumelana kwamanzi kwamapende we-latex. Iphinde ithuthukise ukuqina okuphelele kokuhlanganiswa.

6. Ukuqedwa okubhaliwe:
Ukuqedwa okubhaliwe okuvame ukusetshenziswa ekuhlotsheni kokuhlobisa kuhlomula ekusebenziseni kwe-RDP ngokugcinwa kokushiswa kokuthuthuka okuthuthukisiwe nokuqina.

7. Ukuguqulwa kwe-Asphalt:
I-RDP ingasetshenziswa ekuguqukeni kwe-asphalt ukukhulisa ukuguquguquka nokuqina kwezinto ezisetshenziselwa izinto ezifuywayo ezifana nolwelwesi oluphahla kanye nemigwaqo.

8. Adhesive:
Ezindaweni ezinamathela, i-RDP ithuthukisa amandla anamathela, ukuhlangana nokuvumelana nezimo, okwenza kube lula ukuthola izinhlelo ezahlukahlukene zokubopha.

Ama-polymer polymer powders (i-RDP) ayizinto ezibaluleke kakhulu futhi eziguquguqukayo ezimbonini ezahlukahlukene, ikakhulukazi ekwakhiweni, ezinamathela kanye nezimbobo. Inhlanganisela yayo eyingqayizivele ye-Polymer Njengoba ubuchwepheshe kanye nokwakheka kuyaqhubeka ukuqhubekisela phambili, ukusetshenziswa kwe-RDP kungenzeka bandise, kusiza ekuthuthukiseni izinto zokwakha ezithuthukile nezizinzile nemikhiqizo.
