Umphumela we-RDP ku-Datar-Welveling Data

I-TeatisperibleTwetex Powder (RDP) iyisengezo esibalulekile sodaka lokuzimela. Ingxenye yayo eyinhloko yinto eyimpuphu eyenziwe nge-polymer emulsion ngokusebenzisa eyomile yokufafaza. I-RDP ingahle iphindiswe ngamanzi ukuze yakhe i-emulsion, inikeze izakhiwo ezinhle kakhulu. Lokhu okulandelayo kuhlaziya umthelela we-RDP ngodaka oluzenzakalelayo kusuka ezicini ezine: ukusebenza okusebenzayo, izakhiwo zemishini, ukuqina kanye nokuqina kokusebenza kwe-shrinkage.

1. Ukuthuthuka kokusebenza komsebenzi
I-RDP ingathuthukisa kakhulu uketshezi nokuthambisa kodaka lokuzimela. Umsebenzi wayo ongaphezulu unganciphisa ukungqubuzana kwangaphakathi kodaka, okwenza i-slurry ibe lula futhi ibe lula ekusebenzeni kokwakha. Ngaphezu kwalokho, i-RDP ingakhuphula i-Thixotropy yodaka, okwenza kube lula ukusakaza futhi ibuyiselwe ngokushesha amandla, ngaleyo ndlela iqinisekise ukuthi indawo yokwakha ibushelelezi futhi ingenakuhlukaniswa.

2. Ukuthuthukiswa Kwezakhiwo Zemishini
I-RDP ingathuthukisa kakhulu amandla aguqukayo namandla abugqilayo wodaka oluzimele. Lokhu kungenxa yokuthi ifilimu ye-polymer eyakhiwe yi-RDP ngesikhathi senqubo ye-hydration ingadlala indima emabhulokiwe phakathi kwezinto zokwenza u-clean-based, yenza ngcono ukumelana kwezinto zokuxhumana, futhi kuthuthukise ukumelana nokuqhekeka kwento. Ikakhulu ngaphansi komthwalo wokugoba, izici zokulimala kwe-elastic zefilimu ye-polymer zisiza ukudambisa ukugxilisa ukucindezela, ngaleyo ndlela kuthuthukiswe amandla aguqukayo.

3. Ukuthuthuka kokusebenza kokuqina
I-RDP ingathuthukisa ukuqina kodaka lokuzimela, ekhombisa ukumelana okuhle kwe-freeze-thaw, ukumelana kwamanzi kanye nokuphikiswa kwe-alkali. Ifilimu ye-polymer eyakhiwe yi-RDP ine-vapor ephansi ye-vapor yokuqina nokumelana kahle nokuguguleka kwamakhemikhali, okungavimbela ngempumelelo ukungenela komswakama kwangaphandle nama-ion alimazayo, ngaleyo ndlela kunwebe impilo yenkonzo yodaka. Ngaphezu kwalokho, i-RDP ingaphinde futhi inciphise izinga le-carbonization futhi lithuthukise kakhulu ukuqina ngokwezinto ezibonakalayo ezindaweni eside zokusebenzisa.

4. Ukusebenziseka kahle kokusebenza kwe-shrinkage
Udaka olunqwabelaneni ngokungafanele ngesikhathi senqubo enzima, engaholela kalula emifantu. I-RDP ingadambisa le nkinga ngezindlela ezimbili:

Ifilimu le-polymer lakha isakhiwo senethiwekhi esivumelana nezimo ngesikhathi senqubo enzima, engahlakaza futhi ithole ukucindezelwa kwangaphakathi okubangelwa yi-shrinkage eyomile;
I-RDP ingakhuphula izakhiwo zokugcina amanzi kwi-microssmcucture futhi yehlise kancane izinga lokuhwamuka kwamanzi, ngaleyo ndlela kunciphise amathuba okuqhekeka kwe-shrinkage.
Izindlela zokuqapha nokusetshenziswa okufanele
Yize i-RDP ingathuthukisa kakhulu ukusebenza ngodaka lokuzimela, umthamo wayo kudingeka alawulwe ngokufanele. Ukungezwa ngokweqile kungaholela ezindlekweni ezengeziwe futhi kuthinte amandla kusenesikhathi; Isengezo esanele ingenza kube nzima ukufeza umphumela oyifunayo wokuqiniswa. Ngaphezu kwalokho, izinhlobo ezahlukene ze-RDP (njengemikhiqizo esuselwa ku-ethylene vinyl acetate copolymer noma i-acrylate) inomehluko ekusebenzeni, futhi uhlobo olufanele kufanele lukhethwe ngokuya ngezidingo ezithile.

Njengesengezo se-polymer esisebenzayo, i-RDP idlala indima ebalulekile ekwenzeni ngcono uketshezi, izakhiwo zemishini, ukuqina kanye nokuvimbela ukuqhekeka kodaka lokuzimela. Ngokukhethwa kwezinto ezibonakalayo zesayensi kanye ne-dosage design enengqondo, i-RDP ingathuthukisa kakhulu ukusebenza okuphelele kodaka lokuzimela ukuze ahlangabezane nezidingo zamaphrojekthi ahlukile.
