hpmc rdp esetyenziswa kwi-Cement Render & Plaster EIFS & ETICS
I-JINJI® HPMC ineempawu ezahlukeneyo ezenza isebenze kwaye ikhethwe kwi-EIFS&ETICS.
Inkqubo yebhodi yokufakelwa kwe-Thermal, ngokubanzi iquka i-ETICS (i-EIFS) (i-External Thermal Insulation Composite System / Exterior Insulation Finish System), ukuze kugcinwe iindleko zokufudumeza okanye amandla okupholisa, udaka oluhle lokudibanisa kufuneka lube nalo: kulula ukuxuba, kulula ukuyisebenzisa, imela enganamatheli; Isiphumo esihle sokuchasa ukuxhoma; Ukubambelela kakuhle kokuqala kunye nezinye iimpawu. Udaka lwe-plaster kufuneka lube nalo: kulula ukushukumisa, ukusasazeka lula, imela enganamatheli, ixesha elide lophuhliso, isakhono esihle esimanzi kwilaphu lomnatha, akukho lula ukugubungela kunye nezinye iimpawu. Ezi mfuno zingentla zinokufezekiswa ngokongeza iimveliso ezifanelekileyo ze-cellulose ether ezifana ne-Hydroxypropyl Methyl Cellulose (HPMC) kudaka.
Iimveliso zethu zeselulosi zeHPMC kunye nemveliso yeRDP zibonelela ngolu phuculo lulandelayo kwi-EIFS:
• Ukuphuculwa kwamandla okubambelela kunye nokuguquguquka: i-cellulose inokusebenza kakuhle kokuqina kunye ne-lubricity, enokuphucula amandla okubambelela kunye nokuguquguquka kwe-EIFS yokunamathela.
• Ugcino lwamanzi olwandisiweyo kunye nexesha elongeziweyo lokusebenza: ukunciphisa kakhulu ilahleko yamanzi ekufunxeni isubstrates kwimixube. Amandla okugcina amanzi e-cellulose nawo aphucula ngamandla amandla okuncamathela e-EIFS. Oku kungenxa yokuba izibophelelo zinexesha elaneleyo le-hydration kwaye ngexesha elifanayo azilahlekelwa ngamanzi.
• Ukulungelelaniswa kwemveliso ephuculweyo kunye nerheology: i-cellulose ibalulekile ukulungelelanisa ukuhambelana okufanelekileyo kwiidaka ezintsha. Ukungaguquguquki okufanelekileyo kwenza udaka olutsha luncamathele kakuhle kwiindonga kunye nokwenza umphezulu ube mtyibilizi kwaye ugalelwe lula ngaphandle kokuziva uncangathi. Isisombululo se-aqueous se-MelaColl yinkqubo engeyiyo ye-Newtonian, kwaye iimpawu zesisombululo sayo zibizwa ngokuba yi-thixotropy.
• Ukuphuculwa kwe-hydrophobicity: Emva kokongeza i-cellulose, i-hydrophobicity ye-EIFS iphuculwe, umphumo wokungangeni kwamanzi unyuke kakhulu.
• Ukuphuculwa kokusebenza: Umgangatho ongcono kunye nokunciphisa ukunamathela kweselulosi kunokufakwa ngokulula kwi-EIFS yokuncamathelisa, ekulula ukuyisebenzisa kunye nokwakhiwa, kwaye inokuphucula ngokubonakalayo ukusebenza kakuhle kolwakhiwo.
• Ukuphucula ukusebenza kokwambathisa ngamandla angaphambili agqwesileyo: i-cellulose idibanisa ukudityaniswa kwezinto zepolymer kunye nokuqina kwemathiriyeli ye-inorganic. Banokuqinisekisa amandla okuqala odaka kunye nezinye iipropati ezibalulekileyo ezifunekayo kwi-EIFS kunye nokwakhiwa olutsha.
• Ukuxhathisa okulungileyo kwamanzi, ukuhambelana kakuhle neemveliso eziqhelekileyo: i-cellulose inciphisa kakhulu ilahleko yamanzi kwi-substrates efunxayo kwimixube. Amandla okugcina amanzi e-cellulose nawo aphucula ngamandla amandla okuncamathela e-EIFS. Oku kungenxa yokuba izibophelelo zinexesha elaneleyo le-hydration kwaye ngexesha elifanayo azilahlekelwa ngamanzi.
• Bonisa amandla aphezulu, ukunamathela okuqinileyo, kunye nokumelana ne-alkali: i-cellulose inokugcinwa kakuhle, ipropathi yokuqina, iipropati zemichiza ezizinzileyo zixhathisa ngokufanelekileyo ukuhlaselwa kwe-alkali.
