I-Redisperible Powmer Powder (RDP) isengezo esibalulekile samakhemikhali esisetshenziswa kabanzi kwezinto zokwakha, njengodaka oluxutshwe ngodaka, ukunamathela kwethayela nezinhlelo zokungena. Ingxenye yayo eyinhloko imvamisa i-ethylene-vinyl acetate copolymer (EVA), i-Ethylene-Vinyl Acetate-Ethylene Copolymer (VAE) noma i-Styrene-acrylic acid Copolymer (SA). I-RDP inika amandla izinto zokwakha ukuze zithole izinzuzo ezibalulekile kwizicelo zabo ngokuthuthukisa izakhiwo zabo zomzimba nezamakhemikhali.
1. Thuthukisa ukunqwabelana
Inzuzo ebalulekile ye-RDP ukuthi yathuthukisa kakhulu amandla e-bonding wezinto zokwakha. Ukungeza i-RDP kudaka olomile oluhlanganisiwe lungathuthukisa kakhulu amandla obugqi phakathi kodaka kanye nezindawo ezahlukahlukene. Lokhu kubaluleke kakhulu ngokunamathela kwe-tile njengoba kuqinisekisa ama-tile anamathela ngokuphepha odongeni noma phansi, anciphise ubungozi obunamafutha nokuwa.
2. Thuthukisa ukuguquguquka nokungamelana nokuqhekeka
Ukuguquguquka nokuvuselelwa kokuqhekeka kwezinto zokwakha zinomthelela oqondile ekunciphiseni kwabo nasekufezeni ukuqina kwabo kwenkonzo. I-RDP ithuthukisa kakhulu ukuguquguquka kwezinto zokwakha ifilimu ye-polymer eguqukayo ngaphakathi kokuqukethwe, okwenza kube ngcono ukumelana nokuxineka kwangaphandle kanye nokushintshana, ngaleyo ndlela kunciphise ukwenzeka kwemifantu. Lokhu kubaluleke kakhulu ezinhlelweni ze-wall zodonga zangaphandle (ama-EIF) kanye nezitezi ezizimele.
3. Thuthukisa ukumelana kwamanzi
I-RDP ingahle iphindiswe kabusha ibe yi-emulsion ezinzile empuphu owomile, inikeze okuqukethwe okuhle kakhulu kwamanzi. Ezindaweni ezimanzi, izidumbu ezingezelwe yi-RDP kanye nezikhangiso zingagcina amandla amakhulu ebhondi nokuqina. Lokhu kubaluleke kakhulu ezintweni zokwakha ezindaweni ezimanzi njengezindlu zokugezela namakhishi.
4. Khulisa ukusebenza kokwakhiwa
I-RDP ithuthukisa ukwakhiwa kwezakhiwo zodaka nezinye izinto zokwakha, okwenza kube lula ukwakha nokusebenza. Isibonelo, i-RDP ingathuthukisa ukugcoba nokusebenza kodaka, inciphise ukubonakala kwezinto ezibonakalayo ngesikhathi sokwakha, futhi kusebenze uhlelo lokusebenza lwezokwakha kanye nokulinganisa. Ngaphezu kwalokho, kunganweba amahora okuvula, kunikeze abasebenzi bezokwakha isikhathi esiningi sokujwayela.
5. Khulisa ukumelana kwe-freeze-thaw
Ezimweni ezibandayo zesimo sezulu, izinto zokwakha zidinga ukuba nokuphikiswa okuhle kwe-free-thaw ukuvikela impahla ekuqhekekeni ngenxa yezinguquko zokushisa. I-RDP ithuthukisa ukumelana kwe-freeze-thaw efrijini ngokuthuthukisa ukuguquguquka kwayo nokumelana nokuqhekeka, okuvumela lokho kugcina ukuthembeka kwayo kokuhleleka nokusebenza ngesikhathi semijikelezo ephindaphindwayo.
6. Thuthukisa ukumelana kokugqoka
Ukusetshenziswa kwe-RDP ezindaweni eziphansi kungathuthukisa kakhulu ukumelana nokugqoka nokuqina phansi. Lokhu kubaluleke kakhulu ezintweni zokwakha zomhlaba ezidinga ukubekezelela imvamisa ephezulu kanye nomgwaqo omkhulu wabantu, njengezitolo ezinkulu zezitolo, izitolo zezindiza kanye neziteshi zomgwaqo.
7. Thuthukisa ukusebenza kwe-shrinkage yodaka
Ngesikhathi senqubo enzima yodaka, i-shrinkage ingenye yezimbangela eziphambili zokuqhekeka kanye nokuguquguquka. I-RDP inciphisa i-shrinkage yodaka ngokwakha isakhiwo se-membrane esiguquguqukayo ku-datar, ngaleyo ndlela ivimbele ngempumelelo imifantu ngesikhathi senqubo enzima.
8. Ukuvikelwa Kwezemvelo Nokusimama
Njenge-polymer esolulekayo yamanzi, ukusebenza kwezemvelo kwe-RDP nakho kungenye yezindlela zemboni yokwakha. Ngesikhathi sokukhiqiza kanye nenqubo yokufaka isicelo se-RDP, imvamisa i-NO noma i-Organic Solvent encane, enciphisa ukungcoliswa kwemvelo. Ngaphezu kwalokho, ngoba i-RDP ingathuthukisa kakhulu ukusebenza nokuphila kwezinto zokwakha, inciphisa ngokungaqondile ukusetshenziswa kanye nokuchitha izinsiza, okuhlangabezana nezidingo zokuthuthuka okuqhubekayo embonini yanamuhla yokwakha.
Ukusetshenziswa kwe-latex powder evuselelayo (i-RDP) ezintweni zokwakha ilethe ukuthuthuka okuningi ekwenzeni izinto zokwakha kanye namasu okwakha. Ngokwenza ngcono ukunamathela, ukuguquguquka, ukumelana namanzi, ukumelana kwamanzi, ukumelana kwamanzi kanye nokumelana ne-abrasion, i-RDP ithuthukisa kakhulu impilo yonke nempilo yenkonzo yezinto zokwakha. Ngaphezu kwalokho, izakhiwo ezinobungane zemvelo ze-RDP nazo zikwenza kube yisengezo esisemqoka embonini yanamuhla yokwakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokwakha, i-RDP izodlala indima ebaluleke kakhulu ngokuzayo, ithuthukise ukuthuthukiswa kwezinto zokwakha ezikhundleni eziphezulu nokuvikelwa okwengeziwe kwezemvelo.
