I-polymer powder echithwa kwakhona

I-re-dispersible polymer powder (RDP) yindlela eyomileyo yomgubo wepolymer yokwenziwa enokuthi ixutywe ngokulula namanzi ukwenza i-polymer dispersion. I-RDP isetyenziswa ngokuqhelekileyo njengesongezo kwizinto ezahlukeneyo zokwakha, kubandakanywa udaka oluxubeneyo, i-tile adhesives, kunye ne-insulation yangaphandle kunye neenkqubo zokugqiba (EIFS), ngenxa yeempawu zayo ezintle, ezifana nokuphuculwa kokusebenza, ukubambelela, kunye nokuguquguquka.

I-RDP yenziwe ngeendidi zeepolymers zokwenziwa, ezifana ne-vinyl acetate-ethylene (VAE), i-vinyl acetate-versatile monomer (VeoVa), kunye ne-acrylics. Ezi polymers zenziwa i-polymerized kwindawo enamanzi ukwenza i-latex, ethi emva koko yomiswe kwaye igutywe ibe ngumgubo ocolekileyo. Umgubo unokusasazwa ngokulula emanzini ukwenza i-polymer ezinzileyo.

Iipropati ze-RDP zixhomekeke kuhlobo lwepolymer esetyenzisiweyo, iqondo le-polymerization, ukusabalalisa ubungakanani bamasuntswana, kunye nobukho bezinye izongezo. Ngokubanzi, i-RDP inokumelana kakuhle namanzi, ukuguquguquka, ukunamathela, kunye nokuhambelana nezinye izinto zokwakha. Ifomu yomgubo yeRDP ikwavumela ukugcinwa lula, ukuthuthwa, kunye nokuphathwa.

Kwi-dry-mixed mortar, i-RDP isetyenziselwa ukuphucula ukusebenza, ukunamathela, kunye nokuguquguquka kodaka. I-RDP inokomeleza ugcino lwamanzi kudaka, nto leyo evumela ukusebenza ngcono kunye nokwandisa ixesha lokuvula. I-adhesion ephuculweyo enikezelwa yi-RDP inokunyusa amandla ebhondi phakathi kodaka kunye ne-substrate, okukhokelela ekugqityweni kwexesha elide kunye nexesha elide.

Kwii-adhesives tile, i-RDP isetyenziselwa ukuphucula amandla ebhondi kunye nokuguquguquka kwe-adhesive. Amandla ebhondi aphuculweyo abonelelwa yi-RDP anokunyusa ukuchasana nokucheba kunye nemikhosi ye-peel, okubangela ukuba kubekho ibhondi eqinile kunye neyomelele ngakumbi phakathi kwe-tile kunye ne-substrate. Ukuguquguquka okwandisiweyo okubonelelwa yi-RDP nako kunokunceda ukufunxa uxinzelelo olubangelwa lutshintsho kwiqondo lokushisa kunye nokufuma, ukunciphisa umngcipheko wokuqhekeka okanye ukubola.

Kwi-EIFS, i-RDP isetyenziselwa ukuphucula ukubambelela, ukuguquguquka, kunye nokumelana nemozulu yenkqubo. Ukubambelela okuphuculweyo okubonelelwa yi-RDP kunokunyusa amandla ebhondi phakathi kwebhodi yokugquma kunye ne-substrate, ngelixa ukunyuka kwe-flexibility kunokunceda ukufunxa uxinzelelo olubangelwa ukwanda kwe-thermal kunye nokunciphisa. Ukunganyangeki kwamanzi okubonelelwa yiRDP nako kunokunceda ukuthintela ukungena kwamanzi kunye nokunciphisa umngcipheko womonakalo obangelwa yimijikelo yokunyibilika komkhenkce.

Ukusetyenziswa kwe-RDP kwizinto zokwakha kuneengenelo ezininzi. Okokuqala, i-RDP inokuphucula ukusebenza kwezixhobo, okukhokelela ekugqityweni kwexesha elide kunye nexesha elide. Okwesibini, i-RDP inokuphucula ukusebenza kunye nokuphathwa kwezixhobo, ukunciphisa umngcipheko weempazamo kunye nokuphucula imveliso. Ekugqibeleni, i-RDP inokuphucula ukusebenza kokusingqongileyo kwezinto, ezifana nokunciphisa inani le-volatile organic compounds (VOCs) ekhutshwe ngexesha lokusetyenziswa.

Ukuqukumbela, i-dispersible polymer powder (RDP) yinto eyongezelelweyo kwaye isetyenziswa ngokubanzi kwizinto zokwakha. I-RDP inokuphucula ukusebenza, ukunamathela, kunye nokuguquguquka kodaka oluxubeneyo, i-tile adhesives, kunye ne-EIFS, okukhokelela ekugqityweni kwexesha elide kunye nexesha elide. Ukusetyenziswa kwe-RDP kwizinto zokwakha kuneengenelo ezininzi, kubandakanya ukuphuculwa kwendlela yokusebenza, ukusebenza kakuhle, kunye nokusebenza kokusingqongileyo.
