Ngokuphuhliswa kweshishini lokwakha, iimfuno zokusebenza kwezixhobo zokwakha ziya zisanda, ingakumbi kwinkqubo yodonga lwangaphandle, ekufuneka ibe nokumelana okuhle kakhulu nemozulu, ukumelana namanzi, ukunamathela kunye nokumelana neentanda. Njengezinto ezibalulekileyo zezixhobo zokwakha zanamhlanje,umgubo wepolymer ophinda unyibilike (RDP)kwaye udaka olomileyo ludlala indima ebalulekileyo ekwakhiweni kweendonga zangaphandle zesakhiwo.
Iimpawu zePowder yePolymer ephinda iDispersible
I-Redispersible Polymer Powder yinto eguqulwe yi-polymer, edla ngokwenziwa nge-spray drying polymer emulsions ezifana ne-ethylene-vinyl acetate (EVA), i-acrylic okanye i-styrene-butadiene (SB). Iimpawu zayo eziphambili ziquka:
Ukuphucula ukunamathela: Emva kokufuma, kwakheka ifilimu yepolymer, ephucula kakhulu ukunamathelana phakathi kwemortar kunye ne-substrate, ithintela ukuxobuka nokuqhekeka kwemingxuma.
Ukuphucula ukuguquguquka kunye nokumelana nokuqhekeka: Ukongeza i-Redispersible Polymer Powder kwinkqubo yodaka olungaphandle kodonga kunokuphucula ukuqina kwezinto, kuxhathise ngempumelelo utshintsho lobushushu kunye noxinzelelo, kwaye kunciphise ukuqhekeka.
Yonyusa ukumelana namanzi kunye nokumelana nemozulu: Ifilimu yepolymer eyenziweyo inamandla angcono okungena manzi, nto leyo ephucula amandla okulwa nokuphuma kwamanzi kwi-mortar yangaphandle eludongeni kwaye iyenze ikwazi ukumelana nokukhukuliseka kwemvula.
Ukuphucula ukusebenza kolwakhiwo: Ukuphucula ukunyibilika, ukusebenza kakuhle kunye nokugcinwa kwamanzi kwesamente, ukwandisa ixesha lokwakha kunye nokuphucula ukusebenza kakuhle kolwakhiwo.
Iimpawu zedaka elomileyo
Udaka olomileyo luyimpuphu exutyiweyo eyenziwe ngokuxuba isamente, isanti ye-quartz, izizalisi kunye nezinye izongezo ezahlukeneyo ngomlinganiselo othile. Luneempawu ezilandelayo:
Umgangatho ozinzileyo: Imveliso yemizi-mveliso iqinisekisa ukufana kwezixhobo zedaka kwaye ithintela iimpazamo zomlinganiselo kwindawo.
Ulwakhiwo olulula: Yongeza nje amanzi uze uxube ukuze usebenzise, nto leyo enciphisa ubunzima bokuxuba ngesandla kwindawo ohlala kuyo.
Ukuguquguquka: Iimortars ezinemisebenzi eyahlukeneyo zingalungiswa ngokweemfuno ezahlukeneyo, ezifana nemortar yokubopha, imortar yokuplasta, imortar engangeni manzi, njl.
Ukhuseleko lokusingqongileyo kunye nokonga amandla: Nciphisa inkunkuma yodaka olumanzi lwendabuko kwaye unciphise ungcoliseko kwindawo yokwakha.
Ukusetyenziswa kwePowder yePolymer eDisparable kwidaka elomileyo
Ekwakhiweni kweendonga zangaphandle, iRedispersible Polymer Powder idla ngokusetyenziswa njengesithako esibalulekileyo kwi-dry mortar, nto leyo enika i-mortar ukusebenza okungcono kwaye iyenze ifaneleke kwiimeko ezahlukeneyo zokusetyenziswa:
Isinyithi sokubopha udonga sangaphandle
Inkqubo yokugquma yangaphandle (i-EIFS) idla ngokusebenzisa ibhodi ye-polystyrene (i-EPS), ibhodi ekhutshiweyo (i-XPS) okanye uboya belitye njengomaleko wokugquma, kwaye i-Redispersible Polymer Powder inokuphucula kakhulu ukunamathela kwe-bonding mortar kwibhodi yokugquma, ithintele ukuxobuka nokuwa okubangelwa luxinzelelo lomoya okanye umahluko wobushushu.
Idaka lokuplasta eludongeni lwangaphandle
I-plastering mortar yangaphandle eludongeni isetyenziselwa ukukhusela umaleko wokukhusela nokwakha umphezulu othe tyaba. Emva kokongeza i-Redispersible Polymer Powder, ukuguquguquka kwe-mortar kuyaphucuka, ukumelana nokuqhekeka kuyaphucuka, ukuqhekeka okubangelwa kukutshintsha kobushushu kuyancitshiswa ngempumelelo, kwaye ukuqina kwenkqubo yodonga lwangaphandle kuyaphucuka.
Idaka elingangeni manzi
Iindonga zangaphandle ziguguleka lula yimvula, ingakumbi kwiindawo ezifumileyo okanye ezinemvula. I-Redispersible Polymer Powder inokunyusa uxinano lwe-mortar, iphucule ukusebenza kokungena kwamanzi, inciphise ukungena kwamanzi, kwaye iphucule ukumelana nemozulu kweendonga zangaphandle zokwakha.
Udaka oluzilungelelanisayo
Ngexesha lenkqubo yokuhombisa okanye yokulungisa udonga lwangaphandle, iRedispersible Polymer Powder iphucula ukutyibilika kwemortar ezenzela ngokwayo, ivumela ukuba ilingane ngokukhawuleza kwaye iphucule umgangatho kunye nokusebenza kakuhle kolwakhiwo.
Umgubo wePolymer ophinda unyibilikekwaye udaka olomileyo ludlala indima ebalulekileyo ekwakheni iinkqubo zodonga lwangaphandle. Ukongezwa kweRedispersible Polymer Powder kunika udaka ukunamathela okungcono, ukuguquguquka kunye nokumelana namanzi, kwaye kuphucula uzinzo kunye nobomi benkonzo yenkqubo yodonga lwangaphandle. Ngophuhliso lweshishini lokwakha, olu hlobo lwezinto zokwakha ezintsha luya kusetyenziswa kakhulu kwixesha elizayo, lubonelela ngokhuseleko oluthembekileyo kunye nemiphumo yokuhombisa yokwakha iindonga zangaphandle.
