I-Redispersible Polymer: Ukuphucula ukusebenza kweMveliso

Umgubo wepolymer odispersible (RDP) udlala indima ebalulekileyo ekuphuculeni ukusebenza kweemveliso ezahlukeneyo, ngakumbi kwizinto zokwakha. Nantsi indlela ii-RDPs ezinegalelo ngayo ekuphuculeni ukusebenza kwemveliso:

1. Ukubambelela okuPhuculweyo: Ii-RDPs zonyusa ukuncamathelwa kwezinto zokwakha ezifana nokuncamathelisa iithayile, udaka, kunye nokunikezela kwii-substrates. Benza ibhondi eqinile phakathi kwezinto eziphathekayo kunye ne-substrate, ukuqinisekisa ukunamathela kwexesha elide kunye nokuthintela i-delamination okanye i-detachment.
2. I-Flexibility ephuculweyo kunye ne-Crack Resistance: I-RDPs iphucula ukuguquguquka kunye nokuxhatshazwa kwe-crack yezinto ze-cementitious ezifana ne-mortars kunye ne-self-leveling compounds. Banceda ukunciphisa ukucutheka kunye nokuqhekeka ngokuphucula ukubambisana kunye nokuqina kwezinto eziphathekayo, okubangelwa ukwakhiwa okuzinzileyo kunye nokuqina.
3. Ukunganyangeki kwaManzi kunye noKuhlala ixesha elide: Ii-RDPs zongeza ukuxhathisa kwamanzi kunye nokuqina kwemathiriyeli yokwakha, zizenza zilungele usetyenziso lwangaphakathi nangaphandle. Baphucula ukuxhathisa imathiriyeli ekungeneni kwamanzi, imijikelo yokukhenkceza, kunye nemozulu, ukwandisa ubomi bayo benkonzo kunye nokugcina imfezeko yesakhiwo.
4. Ukuphuculwa kokuSebenza kunye neePropati zeSicelo: Ii-RDP ziphucula ukusebenza kunye neempawu zesicelo sezinto zokwakha, okwenza kube lula ukuxuba, ukusabalalisa, nokugqiba. Baphucula ukuhamba kunye nokuhambelana kwezinto eziphathekayo, okukhokelela kwiindawo ezigudileyo kunye nokugqiba okufanayo.
5. Ukusetwa okuLawulwayo kunye nokuNyanga amaxesha: Ii-RDPs zinceda ukulawula ukusetwa kunye nokunyanga amaxesha ezinto zesamente, okuvumela ukusebenza ngcono kunye namaxesha avulekileyo awandisiweyo. Balawula inkqubo ye-hydration, ukuqinisekisa ukunyanga ngokufanelekileyo kunye nokunciphisa umngcipheko wokumisela kwangaphambili okanye ukomisa.
6. UBumbano kunye nokomelela okomeleziweyo: Ii-RDPs ziphucula ukudityaniswa kunye namandla ezinto zokwakha, okukhokelela kumandla aphezulu ebhondi kunye nokuzinza kwesakhiwo. Baqinisa i-matrix yezinto eziphathekayo, ukwandisa umthamo wayo wokuthwala umthwalo kunye nokuchasana noxinzelelo lomatshini.
7. Uzinzo oluPhuculweyo lwe-Freeze-Thaw: Ii-RDPs zongeza uzinzo lokunyibilika komkhenkce kwizinto zesamente, zinciphisa umngcipheko womonakalo okanye ukuwohloka kwemozulu ebandayo. Banciphisa ukungena kwamanzi kwaye banqande ukubunjwa kweekristale zeqhwa, ukugcina ingqibelelo kunye nokusebenza kwezinto eziphathekayo.
8. Ukuhambelana neZongezo: Ii-RDPs zihambelana noluhlu olubanzi lwezongezo ezisetyenziswa ngokuqhelekileyo kwizinto zokwakha, ezifana ne-accelerators, i-retarders, kunye ne-air-entraining agents. Oku kuvumela ukuguquguquka ekuqulunqweni kwaye kwenza ukulungelelaniswa kweemveliso ukuhlangabezana neemfuno ezithile zokusebenza.

Ngokubanzi, i-polymer powders ehlaziywayo idlala indima ebalulekileyo ekwandiseni ukusebenza kwezinto zokwakha ngokuphucula ukubambelela, ukuguquguquka, ukuxhathisa kwamanzi, ukuqina, ukusebenza, ukusetwa kunye namaxesha okunyanga, ukubumbana, amandla, ukuzinza komkhenkce, kunye nokuhambelana nezongezo. Ukusetyenziswa kwabo kunegalelo ekuveliseni umgangatho ophezulu kunye neemveliso zokwakha ezinokwethenjelwa ezifanelekileyo kwizicelo ezahlukeneyo kunye neemeko zokusingqongileyo.
