I-Redisperible Powmer Powder (RDP) yamakhemikhali wokwakha

Amakhemikhali wokwakha amabanga ezimboni adlala indima ebalulekile ekwenzeni ngcono ukusebenza nokuqina kwezinto zokwakha. Phakathi kwazo, ama-polymer powders (i-RDP) athole ukunakwa okubanzi ngenxa yokuguquguquka okuhlukahlukene kanye nokusebenza ngempumelelo kwizicelo ezahlukahlukene.

1. Qonda i-polymer powter (RDP):

A. Izithako kanye nokwenziwa:

I-polymer powder evuselelekayo iyi-copolymer ye-vinyl acetate ne-ethylene. Inqubo yokukhiqiza ifaka i-emulsion polymerization yale minondomu elandelwa ukomisa isifutho ukukhiqiza i-powder enhle. Izengezo ezingeziwe zingangezwa ukuthuthukisa izakhiwo ezithile njengokuguquguquka, ukunamathela kanye nokumelana kwamanzi.

B. Izici eziyinhloko:

Ukwakheka kwefilimu: I-RDP yakha ifilimu enamathelayo, eguquguqukayo uma ixutshwe namanzi, isiza ukuthuthukisa ukunamathela nokuqina.

Amanzi abuyiselwe amanzi: I-powder isabalalisa kalula emanzini ukwakha i-emulsion ezinzile engaxutshwa kalula nezinye izinto zokwakha.

I-Adhesion: I-RDP ithuthukisa ukunamathela kwezinto zokwakha ezifana nodaka kuya ezinhlotsheni ezahlukahlukene, ukukhuthaza izibopho eziqinile.

Ukuzivumelanisa nezimo

2. Ukusetshenziswa kwe-RDP ezakhiweni zezimboni:

A. Adhesives kanye ne-grout:

I-RDP isetshenziswa kakhulu ekwakhiweni kwama-tile adhesives kanye nama-grouts ukuhlinzeka ngama-adhesion amahle kakhulu ku-substrate nethayili. Ukuguquguquka kwe-polymer kusiza ukwamukela ukunyakaza kwe-substrate, kunciphisa ubungozi bokuqhekeka kwethayela nokuhlehlisa.

B. Izinhlelo Zokufakwa Kwangaphandle Kwangaphandle (Etics):

Ku-ETICS, i-RDP isiza ukuthuthukisa ukuguquguquka nokunamathelisa kwalezi zindodana ezisetshenziselwa ukuvikela amaphaneli wokufakelwa ukuze kwakhiwe izindonga ezingaphandle. Ukuvuselelwa kwamanzi nge-polymer kuqinisekisa ukusebenza okungaguquki ngesikhathi sohlelo lokusebenza.

C. Ukuzimela okuzenzakalelayo:

I-RDP ithuthukisa ukusebenza kwezindawo zokuzibonakalisa ukuzimela ngokwenza ngcono ukunamathela, amandla aguqukayo kanye nokumelana nokuqhekeka. Umphumela wokubushelela, ovundlile usebenza njengesisekelo esifanelekile sokufakwa kwaphansi.

D. Ukulungiswa kodaka:

Emaceleni kodaka, i-RDP ithuthukisa amandla ebhondi phakathi kwezinto zokulungisa kanye ne-substrate ekhona. Lokhu kubalulekile ukufezekisa ukulungiswa okuhlala isikhathi eside ezinhlakeni zokhonkolo.

E. ulwelwelwesi olungaphandle lwamanzi:

I-RDP ifakwe ulwelwesi olungenamanzi ukuthuthukisa ukuguquguquka nokunamathelisa. I-polymer inikela ngekhono likalwelwesi lokumelana nolwelwesi lokumelana nokunyakaza okunamandla nokumelana nokungena kwamanzi.

ezintathu. Izinzuzo zokusebenzisa i-RDP kumakhemikhali ezokwakha:

A. Thuthukisa i-Adhesion:

Ukusetshenziswa kwe-RDP kuthuthukisa ukunamathela kwezinto zokwakha ezinhlotsheni ezahlukahlukene, ukukhuthaza izibopho eziqinile nezihlala isikhathi eside.

B. Ukuvumelana nezimo kanye nokumelana nokuqhekeka:

I-polymer idlulisela ukuguquguquka kwezinto ezibonakalayo, ukunciphisa amathuba okuqhekeka kanye nokwenza ngcono ukuqina kwesakhiwo.

C. Amanzi abuyiselwe:

Ukuvuselelwa kwamanzi kwe-RDP kuqinisekisa ukukhululeka kokuphathwa ngesikhathi sokwakhiwa kanye nesicelo, okuholela emiphumeleni engaguquki futhi ebonakalayo.

D. Ukusebenza okuthuthukile:

Ukungezwa kwe-RDP kuthuthukisa ukusebenziseka kwezinto zokwakha, okwenza kube lula ukuxuba, ukufaka isicelo kanye nokuqeda.

E. Ukuqina:

Ukungezwa kwe-RDP kusiza ukuthuthukisa ukuqina kwezinto zokwakha, kubenza bamelane kakhulu nezici zezemvelo ezinjengokushisa isimo sezulu kanye nomswakama.

Ezine. Izinto okufanele uzibone nezindlela ezinhle kakhulu:

A. Amazinga wethamo:

Umthamo we-RDP ofanelekile ubalulekile ekufezekiseni ukusebenza okufunayo. Amazinga we-DOSAge angahluka ngokuya ngohlelo lokusebenza oluthile, ngakho-ke izincomo zomkhiqizi kufanele zilandelwe.

B. Ukuvumelana Ukuvumelana:

I-RDP kufanele ihambisane nezinye izithako ekwakhekeni. Kunconywa ukuthi kuhlolwe ukuze kuhambisane nosimende, ama-filler nezinye izengezo ukuqinisekisa ukusebenza kahle.

C. Isitoreji nokusingathwa:

Izimo Zokugcina Ezifanele, kufaka phakathi ukuvikelwa kumswakama nokushisa okwedlulele, zibalulekile ekugcineni ikhwalithi nokusebenza ngempumelelo kwe-RDP. Ngaphezu kwalokho, ukunakekelwa kumele kuthathwe ngesikhathi sokuxuba nokwakha ukuvikela imfucuza yezinto ezibonakalayo.

D. Isiqinisekiso sekhwalithi:

Ukukhetha i-RDP esezingeni eliphakeme kusuka kumkhiqizi odumile kubalulekile ekutholeni imiphumela engaguquki nethembekile. Izindlela zokuqinisekisa ezisezingeni eliphakeme njengokuhlola kwe-batch kanye nesitifiketi kufanele kubhekwe.

5. Izitayela zesikhathi esizayo kanye nokwenziwa okusha:

Imboni yezokwakha inamandla ashukumisayo ngocwaningo oluqhubekayo kanye nentuthuko ukwenza ngcono ukusebenza kwamakhemikhali wokwakha, kufaka phakathi i-RDP. Izitayela zesikhathi esizayo zingafaka ukuthuthukiswa kwe-RDPS ethuthukisiwe yemvelo yokusimama kwemvelo, izici zokusebenza okuthuthukisiwe, kanye nezicelo ezibanzi.

eziyisithupha. Ekuphetheni:

I-Redisperible Powter Powder (RDP) iyisithako esiguquguqukayo futhi esisemqoka kumakhemikhali wokwakha ebangeni lezimboni. Izakhiwo zayo ezihlukile, kufaka phakathi ukuqondiswa kwamanzi, ukunamathela, ukuguquguquka nokuqina, kwenze kube yisengezo esibalulekile ezinhlobonhlobo zezicelo ezinjengezifiso zethayela, ama-terics, ama-underbranes angena ngaphansi komhlaba. Ukucatshangelwa ngokucophelela kwemithamo, ukuhambisana, ukugcinwa kanye nokuqinisekiswa kwekhwalithi kubalulekile ukukhulisa izinzuzo ze-RDP kumaphrojekthi wokwakha. Njengoba imboni yezokwakha iyaqhubeka nokuvela, i-RDP kungenzeka ukuthi ibambe iqhaza elibalulekile ekubumbeni ikusasa lezinto zokwakha eziqinile neziphezulu zokusebenza.
