I-redispersible polymer powder (RDP) yongezelela i-polymer ebalulekileyo kwizinto zokwakha zanamhlanje kwaye isetyenziswa ngokubanzi kwi-adhesives ye-tile ukuphucula amandla abo okudibanisa, ukuguquguquka kunye nokuqina.
1. Amagqabantshintshi ngomgubo wepolymer oDispersible
I-polymer powder enokuchithwa kwakhonangumgubo okhululekileyo owenziwe kwi-emulsion ngokutshiza inkqubo yokumisa. Inokuphinda ihlakazwe kwi-polymer dispersion efana ne-emulsion yokuqala emva kokuqhagamshelana namanzi. Iindidi eziqhelekileyo ze-latex powder zibandakanya i-ethylene-vinyl acetate copolymer (EVA), i-acrylates, i-ethylene-acrylate copolymer (VAE), njl. Ngenxa yokugcinwa kwayo kakuhle kokugcinwa, ukuthutha kunye nokwakhiwa kwezinto, isetyenziswa ngokubanzi kwizinto ezixutywe ngodaka, ngokukodwa kwi-adhesives tile. Idlala indima ephambili.
2. Indima yepolymer e-Redispersible powder kwi-adhesives tile
I-adhesives ye-tile ngudaka oluxutywe omileyo olusetyenziselwa ukunamathela iileyile kumphezulu wesiseko, ezinokwakhiwa ngokudibanisa amanzi. Udaka lwesamente lwemveli lunobugwenxa bokunciphisa okukhulu kunye namandla aphantsi okudibanisa, okwenza kube nzima ukuhlangabezana neemfuno zezakhiwo zanamhlanje zokubambelela ngokuqinileyo kunye nokusebenziseka kwizinto ezahlukeneyo zesiseko. Ukuqaliswa kwe-Redispersible polymer powder kuye kwaphucula kakhulu iipropati zomzimba kunye nokusebenza kokwakhiwa kwe-adhesives ye-tile, ngokukodwa kule miba ilandelayo:
Amandla okudibanisa okuphuculweyo: I-polymer particles kwi-latex powder zenza isakhiwo sothungelwano kunye nezixhobo ze-inorganic gelling (ezifana ne-samente), okwandisa ukulunywa komatshini kunye nokudibanisa kweekhemikhali phakathi kwe-adhesive tile kunye ne-tile kunye ne-substrate, ngaloo ndlela iphucula kakhulu amandla okudibanisa.
Ukuphucula ukuguquguquka kunye nokuchasana nokuqhekeka: Iimpawu eziguquguqukayo zepolymer zinika i-adhesive umthamo ophezulu wokuguqulwa, unokuthatha ukuguqulwa okuncinci okubangelwa utshintsho lweqondo lokushisa, ukuhanjiswa koxinzelelo, njl., kunye nokunciphisa umngcipheko wokuqhekeka. Ilungele ngokukodwa iithayile ezinobungakanani obukhulu kunye neziseko eziguquguqukayo.
Ukuphucula ukusebenza kolwakhiwo: I-polymer e-Redispersible powder inika i-adhesive ye-tile ixesha elide elivulekileyo, ukugcinwa kakuhle kwamanzi kunye nokuthambisa, okulungeleyo ukuba abasebenzi bokwakha basebenze kwaye baphucule ukusebenza kakuhle kolwakhiwo.
Ukuphuculwa kokuchasana kwamanzi kunye nokuchasana nokuqhaqhazela: Ifilimu eyenziwe yi-polymer emva kokunyanga inokumelana nokugqwesa kwamanzi kunye nokumelana nemozulu, ukwenzela ukuba i-adhesive tile isengakwazi ukugcina ukusebenza okuzinzileyo kwindawo efumileyo okanye eguqukayo yemozulu.
3. Ukusetyenziswa kunye nezilumkiso
Kwinkqubo yokuvelisa i-adhesives ye-tile, i-polymer e-Redispersible powder idla ngokuxutywa kunye nezinto ezomileyo ze-powder ezifana ne-samente, isanti ye-quartz, i-cellulose ether, njl. ngokomlinganiselo wokwenza umxube owomileyo. Yongeza amanzi acocekileyo kwaye ugxobhoze phambi kokusetyenziswa kwindawo yokwakha. I-dosage yayo ngokuqhelekileyo i-2% ~ 10% yexabiso elipheleleyo le-adhesive powder dry, kwaye ihlengahlengiswa ngokwezinga lokusebenza elifunekayo (njengeC1, C2, S1, S2 level).
La manqaku alandelayo kufuneka aqatshelwe xa usebenzisa:
Kuphephe ukugcina kwindawo yobushushu obuphezulu kunye nokufuma okuphezulu: i-latex powder kulula ukuyidibanisa xa imanzi, kwaye kufuneka itywinwe kwaye igcinwe kwindawo eyomileyo.
Uvavanyo lokuhambelana nezinye izixube: Ezinye iikhemikhali kwifomula zinokuchaphazela ukusebenza kwe-latex powder, kwaye ukuhambelana kufuneka kuqinisekiswe ngovavanyo lwangaphambili.
Gxuma ngokulinganayo: Gxuma ngokucokisekileyo ngaphambi kokwakhiwa ukuze usasaze ngokupheleleyo i-latex powder kwaye uqinisekise ukuba imisebenzi yayo iqhutywe ngokupheleleyo.
4. Amathuba oPhuhliso
Njengoko imathiriyeli yokwakha iqhubeleka nokuphuhlisa isiya kwizalathiso eziluhlaza, ezihambelana nokusingqongileyo kunye nokusebenza, iusetyenziso lweI-polymer powder enokuchithwa kwakhonakwizinto zokuncamathelisa iithayileiya ixhaphaka ngakumbi, ngakumbi kwizakhiwo ezonga umbane nezingakhathaliyo kokusingqongileyo kunye nezakhiwo ezenziweyo. Ukongezelela, uphando kunye nophuhliso lwe-latex powder luqhubela phambili ekusebenzeni okuphezulu, njengokuphuhlisa i-VOC ephantsi, i-high-flexibility, kunye nemveliso yokomisa ngokukhawuleza ukuhlangabezana neemfuno zeemeko ezahlukeneyo zesicelo.
Njengomgangatho wezinto eziguquliweyo eziphezulu zokusebenza kwi-adhesives tile, i-Redispersible polymer powder ineenzuzo ezibalulekileyo ekuphuculeni ukunamathela kwemveliso, ukuguquguquka, kunye nokuxhathisa amanzi. Ukukhetha okunengqiqo kunye nokusetyenziswa kwesayensi ye-latex powder kunokuphucula kakhulu umgangatho wokwakha kunye nokuqina kwe-tile yokupakisha. Ngophuhliso lwenzululwazi yezixhobo kunye nokuqhubela phambili kobuchwepheshe bokwakha, iindawo zokusetyenziswa kwayo kunye nokusebenza kuya kwandiswa ngakumbi kwaye kuphuculwe.
