I-hpmc rdp esetshenziswe ku-Cement Render & Plaster EIFS & ETICS
I-JINJI® HPMC inezinto ezahlukahlukene eziyenza isebenze futhi ithandwe ku-EIFS&ETICS.
Uhlelo lwebhodi lokufaka elishisayo, ngokuvamile elihlanganisa i-ETICS (EIFS) (Isistimu Yangaphandle Yokufakwa Kwe-Thermal Insulation Composite System / I-Exterior Insulation Finish System), ukuze kongiwe izindleko zokushisisa noma amandla okupholisa, udaka oluhle lokubopha ludinga ukuba: kube lula ukuxutshwa, ukusebenziseka kalula, ummese ongagodoli; Umphumela omuhle wokulwa nokulenga; Ukunamathela okuhle kokuqala nezinye izici. Udaka lwe-plaster kudingeka lube: lula ukunyakaziswa, ukusakazeka kalula, ummese ongagxili, isikhathi eside sokukhula, ikhono elihle lokumanzisa indwangu inetha, akulula ukumboza nezinye izici. Lezi zidingo ezingenhla zingafinyelelwa ngokungeza imikhiqizo efanelekile ye-cellulose ether njenge-Hydroxypropyl Methyl Cellulose (HPMC) odakeni.
Imikhiqizo yethu ye-HPMC cellulose kanye nomkhiqizo we-RDP ihlinzeka ngokuthuthuka okulandelayo ku-EIFS:
• Amandla okunamathela athuthukisiwe nokuguquguquka: i-cellulose inokusebenza okuhle kokuqina kanye nokuthambisa, okungathuthukisa amandla okunamathela kanye nokuguquguquka kokunamathela kwe-EIFS.
• Ukugcinwa kwamanzi okuthuthukisiwe kanye nesikhathi sokusebenza esandisiwe: kunciphisa kakhulu ukulahlekelwa kwamanzi abe ama-substrates amuncayo ekubunjweni. Amandla okugcina amanzi e-cellulose nawo athuthukisa kakhulu amandla okunamathela ezinto ezinamathelayo ze-EIFS. Lokhu kungenxa yokuthi ama-binder anesikhathi esanele se-hydration futhi ngesikhathi esifanayo awalahlekelwa amanzi.
• Ukuvumelana komkhiqizo okuthuthukisiwe kanye ne-rheology: i-cellulose iyisihluthulelo esibalulekile sokulungisa ukungaguquguquki okufanele odakeni olusha. Ukungaguquguquki okulungile kwenza ukhonkolo olusha lunamathisele kahle ezindongeni futhi lwenza izindawo ezibushelelezi futhi zisetshenziswe kalula ngaphandle kokuzwakala kokunamathela. Isixazululo esinamanzi se-MelaColl siwuhlelo olungezona olwase-Newton, futhi izakhiwo zesixazululo salo zibizwa ngokuthi i-thixotropy.
• I-hydrophobicity ethuthukisiwe: Ngemva kokwengeza i-cellulose, i-hydrophobicity ye-EIFS ibe ngcono, umphumela wokuvimbela amanzi ukhuphuka kakhulu.
• Ukusebenza okuthuthukisiwe: Ukulinganisa okungcono nokunamathela okuncishisiwe kwe-cellulose kungasetshenziswa kalula kuma-adhesive e-EIFS, okulula ukuwasebenzisa nokwakhiwa, futhi kungathuthukisa kakhulu ukusebenza kahle kokwakha.
• Thuthukisa ukusebenza kwe-coating ngamandla okuqala amahle kakhulu: i-cellulose ihlanganisa ukuhlangana kwezinto ze-polymer nokuqina kwezinto ezingaphili. Bangaqinisekisa amandla okuqala odaka nezinye izakhiwo ezibalulekile ezidingekayo ku-EIFS nokwakhiwa okusha.
• Ukumelana kahle namanzi, ukuhambisana okuhle nemikhiqizo evamile: i-cellulose inciphisa kakhulu ukulahlekelwa kwamanzi kuma-substrates amuncayo ekubunjweni. Amandla okugcina amanzi e-cellulose nawo athuthukisa kakhulu amandla okunamathela ezinto ezinamathelayo ze-EIFS. Lokhu kungenxa yokuthi ama-binder anesikhathi esanele se-hydration futhi ngesikhathi esifanayo awalahlekelwa amanzi.
• Bonisa amandla aphezulu, ukunamathela okuqinile, nokumelana ne-alkali: i-cellulose inokugcinwa okuhle, impahla eqina, Amakhemikhali aqinile amelana ngempumelelo nokuhlaselwa kwe-alkali.
