Ngophuhliso oluqhubekayo lweteknoloji yokwakha yanamhlanje, i-External Insulation and Finish System (EIFS) ibe sisisombululo esibalulekileyo kwintsimi yezakhiwo zokugcina amandla. Ukuphucula ngakumbi ukusebenza kwe-EIFS, ukusetyenziswa kweihydroxypropyl methylcellulose (HPMC)iya isibaluleka ngakumbi. I-HPMC ayipheleli nje ekuphuculeni ukusebenza kolwakhiwo, kodwa ikwanyusa kakhulu ukuqina kunye nokonga amandla kwenkqubo.
Umgaqo wokusebenza kunye nemingeni ye-EIFS
I-EIFS yinkqubo edibeneyo edibanisa udonga lwangaphandle kunye nokugqiba imisebenzi. Ngokukodwa ibandakanya iipaneli zokugquma, izinto zokuncamathelisa, ilaphu le-mesh elomeleziweyo, isiseko sokugquma kunye nokuhombisa umphezulu. I-EIFS inomsebenzi ogqwesileyo wokugquma kwe-thermal kunye neempawu ezikhaphukhaphu, kodwa ikwajongana neengxaki ezithile zobugcisa kwizicelo ezisebenzayo, ezinje ngolwakhiwo olungonelanga lokuncamathelisa, ukuqhekeka kokutyabeka, kunye nokufunxa ngokugqithisileyo kwamanzi. Ezi ngxaki zichaphazela ngokuthe ngqo ukuqina okupheleleyo kwenkqubo. isondo kunye nobuhle.
Iimpawu zokusebenza zeHPMC
I-HPMC yi-ether yeselulosi esebenza kakhulu eyaziwa ngokutyeba kwayo okugqwesileyo, ukugcinwa kwamanzi kunye neempawu zokuguqula kwizinto zokwakha. Iindima zayo eziphambili kwi-EIFS ziquka:
Ukuphuculwa kokugcinwa kwamanzi: I-HPMC iphakamisa kakhulu amandla okugcina amanzi kwi-binder kunye nokugubungela, ukwandisa ixesha lokusebenza lokwakha, ngelixa liqinisekisa ukuba izinto ezisekelwe kwi-samente zixutywe ngokulinganayo ngexesha lenkqubo yokuqina ukuze kugwenywe amandla anganeleyo okanye iintanda ezibangelwa ukulahlekelwa kwamanzi ngokukhawuleza.
Ukulungiswa komsebenzi wokwakha: I-HPMC iphucula iipropati ze-rheological ze-binder kwaye yandisa ukuchasana kwayo ne-anti-sag, yenza ukuba i-coating ibe lula ukuyisebenzisa kwaye inokusabalalisa okulungileyo, ngaloo ndlela iphucula ukusebenza kakuhle kunye nomgangatho.
Amandla okudibanisa okuphuculweyo: Ukuhanjiswa okufanayo kwe-HPMC kunokwandisa i-viscosity kunye nokubambelela kwi-adhesive, ukwenza ibhondi eyomeleleyo phakathi kwebhodi yokufakelwa kunye nodonga.
Ukuphuculwa kokumelana nokuqhekeka: Ngokwandisa ukuguquguquka kodaka, i-HPMC ikhusela ngokufanelekileyo i-coating ekuqhekekeni ngenxa yokutshintsha kweqondo lokushisa okanye ukuguqulwa komgangatho wesiseko.
Ukusetyenziswa okuthe ngqo kwe-HPMC kwi-EIFS
Kwi-EIFS, i-HPMC isetyenziswa ikakhulu kule miba ilandelayo:
Udaka lwe-Bonding: Emva kokongeza i-HPMC, i-bonding mortar inokusebenza okungcono kunye nokunamathela, ukuqinisekisa ukuba ibhodi yokugquma ayiyi kutshintsha ngexesha lenkqubo yokwakha.
Udaka lwe-reinforcement umaleko: Ukongeza i-HPMC kumaleko okomeleza kunokuphucula ukuqina kunye nokumelana nokuqhekeka kodaka, kwaye kwangaxeshanye kuphucule isiphumo sokugquma komnatha we-fiberglass.
I-decorative surface coating: Ukugcinwa kwamanzi kunye neempawu ezityebileyo ze-HPMC zenza iingubo zokuhombisa ngakumbi kunye nesiphumo sokupeyinta sibe ngcono, ngelixa sandisa ixesha lokuvula kunye nokunciphisa iziphene zokwakha.
Ukuphuculwa komsebenzi wokwakha
Ngokusebenzisa i-HPMC kwi-EIFS, ukusebenza kwesakhiwo kuphuculwe kuyo yonke ibhodi:
Ukonga umbane ophuculweyo: Ukudibanisa okuqinileyo phakathi kwebhodi yokugquma kunye nodonga kunciphisa umphumo webhulorho ye-thermal, kunye nokusabalalisa okufanayo kwe-HPMC kuqinisekisa ukunyaniseka kunye nokusebenza kwe-thermal insulation ye-mortar layer.
Ukuphuculwa kokuqina: Udaka olulungisiweyo kunye nokwaleka luxhathisa ngakumbi ukuqhekeka kunye nemozulu, ukwandisa kakhulu ubomi benkonzo yenkqubo.
Ukuphuculwa kobuchule bokwakha: I-HPMC iphucula kakhulu ukusebenza kolwakhiwo, ukwenza inkqubo yokwakha isebenze ngakumbi kwaye ichaneke, kwaye inciphisa iindleko zokuphinda zisebenze.
Umgangatho wenkangeleko ephuculweyo: Ingubo yokuhombisa ithambile kwaye umbala ufana ngakumbi, okwenza isakhiwo sibonakale sihle ngakumbi.
Njengokongeza kwi-EIFS,HPMCinceda ukukhulisa inkqubo ngokusebenza kwayo okugqwesileyo, ibonelela ngezisombululo ezisebenzayo nezihlala ixesha elide kwizakhiwo zanamhlanje zokonga amandla. Kwixesha elizayo, njengoko ishishini lokwakha liqhubeka nokwandisa iimfuno zalo zokusebenza okuphezulu kunye nokuzinza, amathuba okusetyenziswa kwe-HPMC kwi-EIFS aya kuba banzi ngakumbi.
