Redispersible emulsion latex powder

Redispersible emulsion latex powder (RDP) yimpuphu eyomileyo, ekulula ukuyiphatha esetyenziswa ngokuqhelekileyo njengesongezo kwi-mortars kunye ne-plasters ukuphucula ukusebenza kwabo. Ngokuyinhloko iqulunqwe yi-copolymer ye-vinyl acetate kunye ne-ethylene, eveliswa ngenkqubo ye-emulsion polymerization.

I-RDP yimpuphu eguquguqukayo kunye nemisebenzi emininzi enika uluhlu lweenzuzo kwizicelo zokwakha. Iphucula ukubambelela, ukuguquguquka, ukusebenza, kunye nokugcinwa kwamanzi omdaka kunye ne-plasters, evumela ukuba zisetyenziswe kwiimeko ezahlukeneyo. I-RDP isenokomeleza ukomelela kunye nokuqina kwemathiriyeli yokwakha, izenze zimelane nokuqhekeka, ukucutheka, kunye nezinye iindlela zomonakalo.

Ukongeza kusetyenziso lwayo ekwakhiweni, iRDP ikwasetyenziswa nakwamanye amashishini, anjengokugquma, izinto zokuncamathelisa, namalaphu. Kwiingubo, i-RDP isetyenziswe njenge-binder kunye ne-agent-forming agent, ukuphucula ukubambelela kunye nokuqina kweepende kunye neengubo. Kwii-adhesives, i-RDP iphucula amandla kunye nokubambelela kwi-adhesive, okwenza ukuba ilungele ukusetyenziswa kwizicelo ezahlukeneyo. Kwilaphu, i-RDP isetyenziswa njenge-ejenti yokulinganisa, iphucula amandla kunye nokuqina kwelaphu.

Enye yeenzuzo eziphambili zeRDP kukukwazi ukusasazwa ngokulula emanzini emva kokoma. Oku kuthetha ukuba inokugcinwa njengomgubo owomileyo kwaye emva koko ixutywe ngokulula namanzi xa ifuneka, iyenze ibe yinto eluncedo kunye neyongeza indleko. I-redispersibility ye-RDP ixhomekeke kwizinto ezininzi, kubandakanywa ubungakanani be-particle size, i-polymer composition, kunye ne-degree of crosslinking.

I-RDP yongezwa kwi-mortars kunye ne-plasters kwi-concentrations ukusuka kwi-0.5% ukuya kwi-10% ngobunzima, ngokuxhomekeke kwisicelo esithile kunye neempawu ezifunwayo. Idla ngokuxutywa nezinye izithako ezomileyo, ezifana nesamente, isanti, kunye nezigcwalisi, phambi kokuba zidityaniswe namanzi. Umxube ovelayo unokuthi usetyenziswe kwiindawo ezahlukeneyo, kubandakanywa ikhonkrithi, i-masonry kunye nemithi.

I-RDP sisixhobo esikhuselekileyo nesilungele ukusingqongileyo esivavanyelwe ukhuseleko nokusebenza kwayo. Ayiqulathanga naziphi na izinto ezinobungozi kwaye ayibeki nayiphi na imingcipheko ebalulekileyo yempilo okanye yokusingqongileyo. I-RDP ivunyiwe ukuba isetyenziswe ngamaqumrhu alawulayo amaninzi, kuquka i-Arhente yoKhuseleko lweNdalo yase-US (EPA) kunye ne-European Chemicals Agency (ECHA).

Ukuqukumbela, i-emulsion ye-latex i-powder ene-dispersible i-powder eguquguqukayo kunye ne-multi-functional powder ebonelela ngoluhlu lweenzuzo kulwakhiwo kunye namanye amashishini. Amandla ayo okuphucula ukuncamathelisa, ukuguquguquka, ukusebenza, kunye nokugcinwa kwamanzi kuyenza ibe yinto eyongezelelweyo exabisekileyo kwi-mortars, i-plasters, i-coatings, i-adhesives, kunye ne-textiles. Ukusebenziseka kwayo ngokulula, ukhuseleko, kunye nokuhambelana nokusingqongileyo kuyenza ibe lukhetho olukhethwayo kwizicelo ezininzi.
