Umgubo wepolymer ophinda uqhekeke (RDP)sisixhobo esibalulekileyo se-polymer yendalo, esisetyenziswa kakhulu kwiindawo ezininzi ezifana nokwakha, izixhobo zokwakha, imihombiso kunye nemizi-mveliso. Ngokuyintloko yipowder ehamba ngokukhululekileyo efunyanwa yi-emulsions yokomisa nge-spray (ezifana ne-vinyl acetate-ethylene copolymers, i-vinyl acetate-acrylate copolymers, njl.njl.). Le powder ingasasazwa kwakhona ukuze yenze i-emulsion ezinzileyo emva kokuxubana namanzi, ngaloo ndlela igcina ukusebenza kwe-emulsion yokuqala.
1. Iimpawu ezisisiseko
Umgubo wepolymer ophinda uqhekeke uneempawu ezibalulekileyo ezilandelayo:
Ukuphinda kuphinde kunyibilike kakuhle: Ingaphinda inyibilike ngokukhawuleza ibe kwimeko yayo yokuqala emanzini, nto leyo eyinika ukusebenza kakuhle kolwakhiwo lwayo.
Ukusebenza kakuhle kokubopha: Phucula amandla okubopha phakathi kwezinto kunye nesiseko.
Phucula ukuguquguquka: Yandisa ukumelana nokuqhekeka kwezinto kwaye ifanelekile kwezinye izicelo ezifuna ukuguquguquka okuphezulu.
Ukumelana namanzi kunye nokumelana ne-alkali: Isezinzile kwiindawo ezine-alkali ezifana nesamente okanye ilayimu.
Ukulwa nokwaluphala kunye nokumelana nemozulu: Isaqhubeka nokusebenza kakuhle phantsi kwemitha ye-ultraviolet okanye iimeko zemozulu ezinzima.
2. Iindlela eziphambili zokusetyenziswa
I-adhesive yethayile kunye ne-adhesive exhasa ithayile I-Redispersible polymer powder isetyenziswa kakhulu kwi-adhesive yethayile. Iphucula ukuguquguquka kunye namandla okubopha kwezinto ze-adhesive zethayile, ivumela iithayile ukuba zibotshelelwe ngokuqinileyo kwiindawo ezahlukeneyo, ngakumbi ezifanelekileyo kwiithayile ezinkulu, ezingafunxwa ngamanzi amaninzi.
Umgubo wePutty kunye nePutty yangaphandle yodonga Ukongeza umgubo wePolymer ophinda udibane kwiPutty yangaphakathi nangaphandle yodonga kunokuphucula kakhulu ukunamathela, ukumelana namanzi kunye nokusebenza kolwakhiwo lwePutty. Ingakumbi ekusetyenzisweni kodonga lwangaphandle, ukumelana nemozulu okwandisiweyo kudlala indima ebalulekileyo ekuthinteleni ukuqhekeka nokuqhekeka komgubo.
Izinto zomgangatho ezizilinganisayo Umgangatho wesamente ozilinganisayo ufuna ukunyibilika kakuhle kunye nokunamathelana. Umgubo wepolymer ophinda uchitheke unokuphucula ukulula kwawo ekwakheni kunye neempawu zokwenza ifilimu, kwaye unciphise ukuqhekeka kunye nokwahlukana.
Inkqubo yodaka lokufaka i-insulation (njengenkqubo yokufakela i-insulation yangaphandle yodonga lwe-EIFS) Ukongeza umgubo we-polymer ophinda udibane kwi-insulation mortar kunokuphucula ukunamathelana phakathi kwedaka kunye ne-substrate (njengebhodi ye-foam, ibhodi ye-polystyrene, njl.njl.), ukuphucula ukumelana nokuqhekeka, ukumelana neqabaka kunye nokwandisa ubomi benkonzo yenkqubo.
Udaka olungangeni manzi Ukusebenzisa i-RDP kwifomyula yodaka olungangeni manzi kunokuphucula kakhulu ukuguquguquka nokungangeni kwamanzi kwezinto, ukuze zikwazi ukugcina ukusebenza kwazo kwindawo emanzi nehlala ixesha elide.
Ukulungisa i-mortar kunye ne-interface agent Umgubo we-polymer ophinda uqhekeke unokuphucula ukunamathela kunye nokuqina kwe-mortar yokulungisa ukuze kuthintelwe ukuqhekeka kwindawo elungisiweyo. Ukongeza i-RDP kwi-interface agent kunokunyusa amandla okubopha phakathi kweengqimba ezahlukeneyo zezinto.
Izinto ezisekwe kwiGypsum Ukusebenzisa umgubo wepolymer ophinda usetyenziswe kwi-gypsum kunye nee-gypsum binders kunokuphucula amandla azo okubopha, ukumelana nokuqhekeka kunye nokusebenza kolwakhiwo, kwaye yinxalenye ebalulekileyo yezixhobo zokwakha eziluhlaza.
3. Iingenelo zesicelo
Ulwakhiwo olulula Umgubo wepolymer ophinda udibane uhlala ukwimo yomgubo owomileyo kwaye ungaxutywa ngokuthe ngqo nezinye izinto ezomileyo (ezifana nesamente, isanti, njl.njl.) ngaphandle konyango olongezelelweyo lwe-emulsification. Ingasetyenziswa kwindawo leyo ngokongeza amanzi, alungele ukuthuthwa nokwakhiwa.
Ukuphucula ukusebenza okubanzi Ayiphuculi kuphela ukusebenza kwe-mortar ekuqiniseni udonga, kodwa ikwaphucula neempawu zayo zomzimba ezibanzi ezifana nokumelana nokuqhekeka, ukumelana neqabaka, ukumelana nokuguguleka kunye nokuguquguquka. Sisithako esibalulekileyo sokuphucula umgangatho wezixhobo zokwakha.
Ukhuseleko nokhuseleko lokusingqongileyo Umgubo wepolymer ophinda usetyenziswe awunabungozi kwaye awunabungozi, uyahlangabezana neemfuno zezakhiwo zanamhlanje zokukhusela okusingqongileyo kunye nokukhutshwa kwe-VOC ephantsi, kwaye usetyenziswa ngakumbi kwiinkqubo zezakhiwo eziluhlaza.
4. Iindlela zophuhliso lwexesha elizayo
Ngenxa yemfuno ekhulayo yezixhobo zokwakha eziluhlaza nezinobuhlobo nokusingqongileyo kunye nophuhliso oluqhubekayo lwetekhnoloji yokwakha, ifomula kunye nokusebenza kwe-Redispersible polymer powder nazo ziyaphuculwa, zisiya ekunamatheleni okuphezulu, ukumelana nemozulu ephezulu, kunye nokukhutshwa kwe-VOC ephantsi. Kwangaxeshanye, kudityaniswe neendawo ezintsha zezinto ezifana ne-nanotechnology kunye nezinto ezisekelwe kwi-bio, ukusetyenziswa okuzinzileyo nokusebenzayo kwe-RDP kuya kuba yinto ephambili kuphando nophuhliso lwexesha elizayo.
Njengesongezelelo sepolymer esisebenzayo,I-RDPIdlala indima engenakutshintshwa kwizakhiwo zanamhlanje nakwizinto zokwakha zoshishino ngenxa yokusebenza kwayo okugqwesileyo kunye noluhlu olubanzi lwezicelo. Ukusuka ekubekweni kwethayile ukuya ekulinganisweni kodonga, ukusuka ekwakhiweni komgangatho ukuya ekulungisweni kwamanzi, ijolise ekuphuculeni ukusebenza kwezinto kunye nokusebenza kakuhle kolwakhiwo, kwaye ikhuthaza lonke ishishini lezinto zokwakha ukuba lihambe liye kumgangatho ophezulu kunye nezikhokelo ezinobuhlobo nokusingqongileyo.
