Indlela yokusebenza yeRedispersible Polymer Powder (RDP) kudaka olomileyo

I-Redispersible Polymer Powder (RDP)sisongezelelo esibalulekileyo kwimixube yodaka olomileyo, ebonelela ngoluhlu lweenzuzo ezifana nokuphuculwa kokuncamathela, ukudibanisa, ukuguquguquka, kunye nokusebenza. Indlela yokusebenza kwayo ibandakanya izigaba ezininzi, ukusuka ekusasazeni emanzini ukuya ekusebenzisaneni namanye amacandelo kumxube wodaka. Makhe sihlolisise indlela eneenkcukacha:

Ukusasazwa emanzini:
Amasuntswana e-RDP enzelwe ukuba asasazeke ngokukhawuleza nangokufanayo emanzini ngenxa yobume be-hydrophilic. Emva kokongezwa kwamanzi kumxube wodaka olomileyo, ezi ngqungquthela zihlutha kwaye zihlakazeke, zenze i-colloidal suspension ezinzileyo. Le nkqubo yokusabalalisa ibonisa indawo enkulu yendawo yepolymer kwindawo engqongileyo, iququzelele intsebenziswano elandelayo.

Ukwenziwa kwefilimu:
Njengoko amanzi eqhubeka ukufakwa kumxube wodaka, iinqununu ze-RDP ezihlakaziweyo ziqala ukukhupha amanzi, zenza ifilimu eqhubekayo malunga neengqungquthela ze-cementitious kunye nezinye izinto. Le filimu isebenza njengomqobo, ukuthintela ukudibanisa ngokuthe ngqo phakathi kwezinto ze-cementitious kunye nomswakama wangaphandle. Oku kubalulekile ekwehliseni ukungena kwamanzi, ukomeleza ukuqina, kunye nokunciphisa umngcipheko we-efflorescence kunye nezinye iindlela zokuwohloka.

Ukuncamathela okuPhuculweyo kunye noManyano:
Ifilimu ye-polymer eyenziwe yi-RDP isebenza njenge-agent edibeneyo, ikhuthaza ukunamathela phakathi kodaka kunye ne-substrates ezahlukahlukeneyo ezifana nekhonkrithi, i-masonry, okanye iithayile. Ifilimu iphinda iphucule ukubambisana ngaphakathi kwe-matrix yodaka ngokuvala izikhewu phakathi kwamaqhekeza, ngaloo ndlela iphucula amandla onke kunye nokunyaniseka kodaka oluqinileyo.

Ukuguquguquka kunye noKuxhathisa i-Crack:
Enye yeenzuzo eziphambili ze-RDP kukukwazi ukunikezela ukuguquguquka kwimatrix yodaka. Ifilimu ye-polymer ithatha ukunyakaza okuncinci kwe-substrate kunye nokwandiswa kwe-thermal, ukunciphisa umngcipheko wokuqhekeka. Ukongeza, i-DPP yonyusa amandla okuqina kunye ne-ductility yodaka, iphucula ngakumbi ukuchasana kwayo nokuqhekeka phantsi kwemithwalo emileyo kunye neguqukayo.

Ugcino lwamanzi:
Ubukho be-RDP kumxube wodaka kunceda ukulawula ukugcinwa kwamanzi, ukuthintela ukuvela komphunga okukhawulezayo ngexesha lokuqala lokunyanga. Eli xesha elongeziweyo le-hydration likhuthaza i-cement hydration epheleleyo kwaye iqinisekisa uphuhliso olufanelekileyo lweempawu zomatshini, ezifana nokunyanzeliswa kunye nokuguquguquka kwamandla. Ngaphezu koko, ukugcinwa kwamanzi alawulwayo kunegalelo ekuphuculeni ukusebenza kunye nexesha elide elivulekileyo, ukuququzelela ukusetyenziswa okulula kunye nokugqitywa kodaka.

Ukomelezwa koKuhlala:
Ngokuphucula ukubambelela, ukuguquguquka, kunye nokuchasana nokuqhekeka, i-DPP iphakamisa kakhulu ukuqina kwezicelo zodaka olomileyo. Ifilimu ye-polymer isebenza njengesithintelo sokukhusela ekungeneni komswakama, ukuhlaselwa kweekhemikhali, kunye nongcoliseko lokusingqongileyo, ngaloo ndlela ukwandisa ubomi benkonzo yodaka kunye nokunciphisa iimfuno zokugcina.

Ukuhambelana nezongezo:
iRDPibonisa ukuhambelana okugqwesileyo kunye nezongezelelo ezahlukeneyo ezidla ngokusetyenziswa kwimixube yodaka olomileyo, njengee-intrainers zomoya, ii-accelerators, iiretarders, kunye ne-pigments. Oku kuguquguquka kuvumela ukulungelelaniswa kweempawu zodaka ukuhlangabezana neemfuno ezithile zokusebenza kwizicelo ezahlukeneyo kunye neemeko zokusingqongileyo.

indlela yokusebenza yepolymer ehlakazekayo yomgubo kudaka olomileyo ibandakanya ukusasazwa emanzini, ukubunjwa kwefilimu, ukunamathela okuphuculweyo kunye nokudibanisa, ukuguquguquka kunye nokumelana nokuqhekeka, ukugcinwa kwamanzi, ukunyusa ukuqina, kunye nokuhambelana nezongezo. Ezi ziphumo zidibeneyo zinegalelo ekusebenzeni okuphuculweyo, ukusebenza, kunye nokuqina kweenkqubo zodaka olomileyo kuluhlu olubanzi lwezicelo zokwakha.
