Ngokuthuthuka okuqhubekayo kobuchwepheshe besimanje bokwakha, i-External Insulation and Finish System (EIFS) isibe yisixazululo esibalulekile emkhakheni wezakhiwo ezonga amandla. Ukuze kuthuthukiswe ukusebenza kwe-EIFS, ukusetshenziswa kwei-hydroxypropyl methylcellulose (HPMC)iya ngokuya ibalulekile. I-HPMC ayigcini nje ngokuthuthukisa ukusebenza kokwakhiwa, kodwa futhi ithuthukisa kakhulu ukuqina nokonga amandla kwesistimu.
Umgomo wokusebenza nezinselelo ze-EIFS
I-EIFS iwuhlelo oluyinhlanganisela oluhlanganisa ukwahlukanisa odongeni kwangaphandle nemisebenzi yokuqeda. Ihlanganisa ikakhulukazi ama-insulation panel, ama-adhesives, indwangu ye-mesh eqinisiwe, i-base coating kanye ne-decorative surface coating. I-EIFS inokusebenza okuhle kakhulu kokufakwa kwe-thermal nezici ezingasindi, kodwa futhi ibhekana nezinkinga ezithile zobuchwepheshe ekusebenziseni okungokoqobo, njengokusebenza okwanele kokwakha okunamathelayo, ukuqhekeka kokumboza, nokumunca amanzi ngokweqile. Lezi zinkinga zithinta ngqo ukuqina okuphelele kohlelo. ubulili kanye nobuhle.
Izici zokusebenza zeI-HPMC
I-HPMC iyi-ether ye-cellulose esebenza kahle kakhulu eyaziwa ngokujiya kwayo okuhle kakhulu, ukugcinwa kwamanzi kanye nezakhiwo zokuguqula ezintweni zokwakha. Izindima zayo eziyinhloko ku-EIFS zihlanganisa:
Ukugcinwa kwamanzi okuthuthukisiwe: I-HPMC ithuthukisa kakhulu amandla okugcina amanzi we-binder kanye ne-coating, inweba isikhathi sokusebenza sokwakha, kuyilapho iqinisekisa ukuthi izinto ezisekelwe kusimende zifakwe emanzini ngokulinganayo ngesikhathi senqubo yokuqina ukuze kugwenywe amandla anganele noma imifantu ebangelwa ukulahlekelwa kwamanzi ngokushesha.
Ukuthuthukiswa kokusebenza kokwakha: I-HPMC ithuthukisa izici ze-rheological ze-binder futhi ikhulise ukumelana kwayo ne-anti-sag, okwenza ukunamathela kube lula futhi kube nokusabalala okuhle, ngaleyo ndlela ithuthukise ukusebenza kahle nekhwalithi yokwakha.
Amandla okubopha athuthukisiwe: Ukusatshalaliswa okufanayo kwe-HPMC kungakhulisa i-viscosity nokunamathela kokunamathelayo, kwakhe isibopho esiqinile phakathi kwebhodi lokufaka nodonga.
Ukumelana nokuqhekeka okuthuthukisiwe: Ngokwandisa ukuguquguquka kodaka, i-HPMC ivimbela ngokuphumelelayo ukunamathela ekuqhekekeni ngenxa yokushintsha kwezinga lokushisa noma ukuguqulwa kwesendlalelo sesisekelo.
Ukusetshenziswa okuqondile kwe-HPMC ku-EIFS
Ku-EIFS, i-HPMC isetshenziswa kakhulu kulezi zici ezilandelayo:
I-Bonding mortar: Ngemva kokwengeza i-HPMC, udaka oluyisibopho lusebenza kangcono kanye nokunamathela, okuqinisekisa ukuthi ibhodi lokufakwayo ngeke ligudluke phakathi nenqubo yokwakha.
Udaka lwesendlalelo sokuqinisa: Ukwengeza i-HPMC kungqimba yokuqinisa kungathuthukisa ukuqina nokumelana nokuqhekeka kodaka, futhi ngesikhathi esifanayo kuthuthukise umphumela wokumboza we-fiberglass mesh.
I-Decorative surface coating: Izakhiwo ezigcina amanzi kanye nokujiya ze-HPMC zenza ukunamathela okuhlotshiswe kube ngokulingana kanye nomthelela wokupenda ube ngcono, kuyilapho kunwetshwa isikhathi sokuvula futhi kuncishiswe amaphutha okwakha.
Ukwenza ngcono ukusebenza kwesakhiwo
Ngokusebenzisa i-HPMC ku-EIFS, ukusebenza kwebhilidi kuyathuthukiswa kulo lonke:
Umthelela othuthukisiwe wokonga amandla: Isibopho esiqinile phakathi kwebhodi lokufakwa ngaphakathi nodonga kunciphisa umphumela webhuloho elishisayo, futhi ukusatshalaliswa okufanayo kwe-HPMC kuqinisekisa ubuqotho nokusebenza kokufakwa okushisayo kwesendlalelo sodaka.
Ukuqina okuthuthukisiwe: Udaka oluguquliwe kanye nokunamathela kumelana kakhulu nokuqhekeka kanye nesimo sezulu, okunweba kakhulu impilo yesevisi yesistimu.
Ukusebenza kahle kokwakha okuthuthukisiwe: I-HPMC ithuthukisa kakhulu ukusebenza kokwakha, yenza inqubo yokwakha isebenze kahle futhi inembe kakhudlwana, futhi yehlise izindleko zokusebenza kabusha.
Ikhwalithi yokubukeka elungiselelwe: Ingubo yokuhlobisa iphansi futhi umbala ufana kakhulu, okwenza isakhiwo sibonakale sisihle kakhulu.
Njengesengezo esibalulekile ku-EIFS,I-HPMCisiza ukuthuthukisa isistimu ngokusebenza kwayo okuhle kakhulu, ihlinzeka ngezixazululo eziphumelelayo nezihlala isikhathi eside zezakhiwo zesimanje ezonga amandla. Ngokuzayo, njengoba imboni yezokwakha iqhubeka nokwandisa izidingo zayo zokusebenza okuphezulu nokuzinza, amathemba okufaka isicelo e-HPMC ku-EIFS azoba banzi nakakhulu.
