Indima yePolymer Powder eDispersible (RDP) kwi-Cement Mortar

Kulwakhiwo lwangoku, ukufuna ukuqina, ukuguquguquka, kunye nokuzinza kuye kwaqhuba ukwamkelwa kwezinto eziphambili.I-Redispersible Polymer Powder (RDP)umi phambili kule nguqu, eguqula iinkqubo zesamente zemveli. Njengenxalenye ephambili kwiidaka ezisebenza kakhulu,iRDPiphucula ukuncamathelisa, ukuthintela amanzi, kunye neempawu zoomatshini, nto leyo eyenza ibe yimfuneko kubakhi bezakhiwo, iikontraka kunye nabenzi behlabathi.

UkuqondaInokuphinda ihlakazweIpolymerUmgubo(RDP)

Umgubo wepolymer odispersible ngumgubo wepolymer olungisiweyo ofunyenwe ngokutshiza ukomisa ibhinari okanye i-ternary copolymer yevinyl acetate kunye ne-versatate vinyl ester okanye i-ethylene okanye i-acrylate, kwaye inokuhleleka kwakhona. Xa ixutywe namanzi, iphinda ichithwe kwi-emulsion ezinzileyo, yenza ifilimu ekhuselayo edibanisa i-aggregates kunye neengqungquthela zesamente.

Le nkqubo iphucula kakhulu ukusebenza kodaka ngokuvala izikhewu phakathi kokuqina kwesamente eqhelekileyo kunye nemfuno yolwakhiwo lwangoku yokomelela.

Iingenelo ezingundoqoyeUmgubo wePolymer ophinde uhlakazwe (iRDP)

• · Ukuncamathela okuphuculweyo: I-RDP idala umanyano olomeleleyo phakathi kodaka kunye neesubstrates ezifana neethayile, izitena, okanye ikhonkrithi, ukunciphisa umngcipheko wokugrunjwa nokudilizwa.
• · Ukubhetyebhetye kunye noKuxhathisa i-Crack: Ngokwenza ifilimu enwebekayo, iRDP ithomalalisa ukuqhekeka okubangelwa kukwandiswa kobushushu okanye intshukumo yesubstrate, yandisa ubomi bodaka.
• · Ukusebenza: I-RDP iphucula ukungaguquguquki kodaka, ikwenza kube lula ukufaka isicelo kunye nokuqinisekisa ukhuseleko olufanayo.
• · Ukuqina: Ifilimu yepolymer iphakamisa ukuxhathisa kwi-abrasion, iikhemikhali, kunye nomjikelo wokunyibilika komkhenkce, olungele indawo ezingqongileyo.

Kutheni Songeza iPolymer Powder eRedispersible (RDP) kudaka lwesamente?

Ngelixa i-samente inika amandla acinezelayo, ayinakuguquguquka kunye nokuxhathisa kwamanzi.I-JINJI CHEMICAL'siRDPilungisa le mida ngokuthi:

• √Bond Amandla: Iphumelele ukuya kuthi ga2.0 MPa amandla okuncamathelisa, ilungele i-adhesives tile kunye neenkqubo zangaphandle zokugquma.
• √I-Crack Resistance: Yehlisa iintanda ezicuthekayo40%–60%xa kuthelekiswa nodaka olungalungiswanga.
• √Ukugcinwa kwamanzi: Igcina iimeko ezifanelekileyo ze-hydration, ezibaluleke kakhulu kwiibhedi ezinqabileyo.
• √Amandla e-Flexural: Ukuphucula ukuguquguquka ngo15%–25%, ukuthintela i-delamination kwiindawo eziguquguqukayo.
• √Umanyano: Yandisa ukuxhathisa kwe-sag kwizicelo ezithe nkqo njengokutyabeka.

Nangona kunjalo, ngokwendlela eyahlukileyo yokwakheka kodaka, kunye nokongezwa kokuguqulwa komgubo wepolymer okuphinda kuchaphazeleke kuya kuchaphazela ukusebenza kodaka:

Inani elongezelelweyo le-polymer powder elidispersible yi-Inani elongezelelweyo le-polymer powder li-1% -2%, eliphucula amandla, ukuchasana kwamanzi kunye nokuguquguquka komdaka;Inani elongezelelweyo le-polymer powder li-dispersible li-2% -5%, eyenza ifilimu ye-polymer ye-reticulation kwi-mortar, kwaye ngokucacileyo iphucula amandla kunye nokuguquguquka kodaka kwiindawo ezahlukeneyo zezulu kunye ne-interfaces.
Ngokwethiyori, iqondo lobushushu beglasi yomgubo ongaphantsi kwe-5 ℃ yemveliso ngokwayo ibhetyebhetye ngakumbi, ikakhulu isetyenziswa kudaka lwangaphandle lokugquma, ngelixa iqondo lobushushu beglasi yomgubo ongaphezulu kwe-10 ℃ lisetyenziswa ikakhulu kwincanyatheliso kunye nodaka oluzilinganisayo.

Ukwakha Ngcono ngeI-RDP ye-JINJI CHEMICAL ukusukela namhlanje!

I-Redispersible Polymer Powder (RDP)ayisesiso nje isongezo—isisiseko solwakhiwo lwale mihla. Ngamashumi eminyaka yobungcali,I-JINJI CHEMICALigxile kuphando, ukuphuhlisa, ukuvelisa, kunye nokusasaza umgangatho ophezulu womgubo wepolymer odispersible wokwakhiwa kunye nosetyenziso lwemizi-mveliso. Njengenkokeli ethembekileyo kwintsimi yomgubo wepolymer, sihambisa izisombululo ezilungiselelweyo ezichaza into enokwenzeka kulwakhiwo.
