Kwintsimi ye-polymer adhesives, ukunyuka kokuguquguquka kuye kwalandelwa iminyaka emininzi. Ngemfuno yeemveliso ezihlala ixesha elide kunye nezomelele ngakumbi, uphuhliso lwezincamathelisi zepolymer eziguquguqukayo ziye zaba yinto ephambili. Olunye uphuhliso olubonise isithembiso kusetyenziso lwe-RDP polymer binder blends.
I-RDP, okanye i-polymer powder ephindwe kabini, i-polymer eyomisiwe kwaye yagutywa ibe yifom yomgubo, enokuthi iphinde isasazwe kulwelo ukwenza i-emulsion entsha okanye i-coating. I powder yenziwe kwiipolymers ezahlukeneyo ezibandakanya i-vinyl acetate-ethylene (VAE), i-vinyl acetate-ethylene (VAEO), kunye ne-vinyl acetate-ethylene ester (VA-VE). I-RDP isetyenziswe ngokubanzi kwi-adhesive kunye ne-coating formulations kunye nodaka kunye nokusetyenziswa kwekhonkrithi. Iimpawu zayo ezigqwesileyo zokwenza ifilimu kunye nokukwazi ukuphucula ukunamathela, ukuqhutyelwa phambili kunye nokuguquguquka kwenza kube lukhetho oludumileyo kumashishini amaninzi.
Xa ixutywe nezinye iipolymers ezifana ne-polyvinyl acetate (PVA), i-rabha ye-styrene-butadiene (SBR) kunye ne-carboxyl styrene-butadiene rubber (XSB), i-RDP inokuphucula kakhulu ukuguquguquka kwemveliso yokugqibela. Oku kungenxa yokukwazi kwe-RDP ukunyusa iplastiki kunye ne-elasticity yeepolymers. Ngokusebenzisa ezi zithako ukwenza ifilimu eyomeleleyo, i-RDP inokuphucula amandla ebhondi yemveliso yokugqibela kwaye yenza kube nzima ukumelana nokuqhekeka kunye nokuguqulwa.
Enye yeenzuzo eziphambili zokusebenzisa i-RDP polymer adhesive blends kukuguquguquka kwazo. Ingasetyenziselwa kwiintlobo ezahlukeneyo ze-substrates, kubandakanywa ukhuni, ikhonkrithi kunye nesinyithi, ngaphandle kokubingelela ukusebenza okanye ukuqina. Ukongeza, inokuqulunqwa ngamaqondo ahlukeneyo okuguquguquka ngokuxhomekeke kwiimfuno ezifunwayo zokusetyenziswa kokuphela. Oku kuvumela ukuguquguquka okukhulu kuyilo lwemveliso kunye nokukwazi ukudala izisombululo zezicelo ezithile.
Olunye uncedo lokusebenzisa i-RDP polymer binder blend kukusebenza kwayo kweendleko. Ixabiso layo eliphantsi xa lithelekiswa nezinye iintlobo zokuncamathelisa zenza ukuba ibe lukhetho olunomtsalane kumashishini amaninzi. Ikwalula ukuyisebenzisa kwaye inokufakwa kwiiresiphi ezikhoyo ngaphandle kotshintsho olukhulu.
I-RDP polymer binder binder blends inokuphucula umgangatho opheleleyo wemveliso yokugqibela. Ngenxa yokuba inika ukuguquguquka okukhulu kunye nokuphucula ukubambelela, yandisa ubomi bemveliso kwaye inciphisa imfuno yokulungiswa rhoqo okanye ukutshintshwa. Ngokuhamba kwexesha, oku kunokubangela ukonga iindleko ezibalulekileyo kunye nokwaneliseka okwandisiweyo kwabathengi.
Ukusetyenziswa kwe-RDP polymer binder blends kubonisa isithembiso esikhulu ekunyuseni ukuguquguquka kwiimveliso ezahlukeneyo. Ukuguquguquka kwayo, ukusebenza kakuhle kweendleko, kunye nokukwazi ukuphucula umgangatho uwonke wemveliso yokugqibela kuyenza ibe lukhetho oluxabisekileyo kumashishini amaninzi. Ukusetyenziswa kwemixube encamathelayo ye-polymer ye-RDP kusenokwenzeka ukuba iqhubeke nokukhula ekuthandeni njengoko imfuno yeemveliso ezihlala ixesha elide kunye nezomeleleyo ziqhubeka zisanda.
