Ukumisela uMyinge oLungileyo we-HPMC kwi-Insulation yangaphandle kunye neNkqubo yokuQeqesha (EIFS)
I-Exterior Insulation and Finish System (EIFS) sisixhobo sokwakha esisetyenziswa ngokubanzi esibonelela zombini ukugquma kunye nokugqiba ukuhombisa kwisakhiwo sangaphandle.Iqukethe izinto ezininzi, kubandakanya idyasi yesiseko, umaleko wokugquma, umnatha wokuqinisa, kunye nedyasi yokugqiba.IHydroxypropyl methylcellulose (HPMC) isoloko idityaniswa kwidyasi yesiseko njengesibophelelo kunye nesingqimba sokuphucula ukusebenza kunye nokusebenza kwe-EIFS.Nangona kunjalo, ukumisela umlinganiselo ofanelekileyo we-HPMC kubalulekile ukufezekisa iipropati ezifanelekileyo kunye nokuqinisekisa ukuqina kwexesha elide lenkqubo.
Ukubaluleka kwe-HPMC kwi-EIFS:
I-HPMC yipolymer esekwe kwiselulosi ephuma kumaplanga okanye kwimicu yomqhaphu.Iyanyibilika emanzini kwaye yenza into efana nejeli xa ixutywe nolwelo.Kwimveliso ye-EIFS, i-HPMC isebenza njenge-binder, iphucula ukubambelela phakathi kwengubo yesiseko kunye ne-substrate ephantsi.Kwakhona kwandisa ukusebenza komxube, ukuvumela ukusetyenziswa lula kunye nokugqitywa okugudileyo.Ukongeza, i-HPMC ibonelela ngokuphucuka kokumelana nokuqhekeka, ukugcinwa kwamanzi, kunye nokuqina okupheleleyo kwe-EIFS.
Izinto ezichaphazela umlinganiselo we-HPMC:
Izinto ezininzi zinefuthe ekukhethweni komlinganiselo ofanelekileyo we-HPMC kwimveliso ye-EIFS:
Ukuhambelana kunye nokuSebenza: Umlinganiselo we-HPMC kufuneka ulungelelaniswe ukuze ufezekise ukuhambelana okufunwayo kunye nokusebenza kwengubo yesiseko.Umlinganiselo ophezulu we-HPMC wonyusa i-viscosity, ukhokelela kumxube ongqindilili onokuba nzima ukuwusebenzisa.Ngokwahlukileyo, umlinganiselo ophantsi unokukhokelela ekuqhubeni kwe-runny, ukuphazamisa ukunamathela kunye nokusebenza.
I-Substrate Compatibility: Umlinganiselo we-HPMC kufuneka uhambelane ne-substrate ukuqinisekisa ukunamathela ngokufanelekileyo.Ii-substrates ezahlukeneyo, ezifana nekhonkrithi, i-masonry, okanye iinkuni, zinokufuna ukwahluka kweereyishini ze-HPMC ukufezekisa ukuhlangana okufanelekileyo kunye nokuthintela ukubola.
Iimeko zokusingqongileyo: Iimeko zokusingqongileyo, ezifana nobushushu kunye nokufuma, zinokuchaphazela ixesha lokunyanga kunye nokomisa kwe-EIFS.Umlinganiselo we-HPMC kufuneka ulungelelaniswe ngokufanelekileyo ukulungiselela le miqathango kunye nokuqinisekisa ukusetwa okufanelekileyo kunye nokomisa ngaphandle kokuphazamisa ingqibelelo yenkqubo.
Ukumisela umlinganiselo weHPMC oLungileyo:
Ukumisela owona mlinganiselo ufanelekileyo we-HPMC kwimveliso ye-EIFS, uthotho lweemvavanyo zaselabhoratri kunye novavanyo lwasendle kufuneka lwenziwe.La manyathelo alandelayo angalandelwa:
Uphuhliso Loqulunqo: Qala ngokulungiselela imixube yebhatyi yesiseko eyahlukeneyo enemilinganiselo eyahlukeneyo yeHPMC ngelixa ugcina amanye amacandelo engaguquguquki.Ulungelelwaniso lunokwandiswa ngokunyukayo okanye luncitshiswe ukuhlola impembelelo yabo ekusebenzeni nasekusebenzeni.
Uvavanyo lokuSebenza: Vavanya ukusebenza koyilo ngalunye ngokuqwalasela izinto ezifana ne-viscosity, ukukhululeka kwesicelo, kunye nokuthungwa.Ukuqhuba iimvavanyo ze-slump kwaye ujonge ukusasazeka kunye neempawu zokubambelela ukuqinisekisa ukuba isambatho sesiseko singasetyenziswa ngokufanayo.
Ukubambelela kunye namandla okudibanisa: Yenza iimvavanyo zokubambelela usebenzisa iindlela ezisemgangathweni ukumisela amandla ebhondi phakathi kwengubo yesiseko kunye nee-substrates ezahlukeneyo.Oku kuya kunceda ukuchonga umlinganiselo obonelela ngokunamathela ngokufanelekileyo kunye nokuhambelana neendawo ezahlukeneyo.
UVavanyo lweMechanical and Durability: Vavanya iipropathi zoomatshini zeesampulu ze-EIFS eziveliswe ngomlinganiselo owahlukileyo we-HPMC.Ukuqhuba iimvavanyo ezinje ngokuqina kwe-flexural, ukuchasana kwempembelelo, kunye nokufunxa kwamanzi ukumisela umlinganiselo onika eyona ndibaniselwano yamandla kunye nokuqina.
Iimvavanyo zeNdawo kunye nokuHlolwa kokuSebenza: Emva kokukhetha umlinganiselo wokuqala we-HPMC kwiimvavanyo zaselabhoratri, qhuba iimvavanyo zentsimi kwiimeko zehlabathi lokwenyani.Ukubeka esweni ukusebenza kwenkqubo ye-EIFS kwithuba elongeziweyo, kuthathelwa ingqalelo imiba efana nokuba sesichengeni semozulu, ukuguquguquka kwamaqondo obushushu, kunye neemfuno zokulondolozwa.Lungisa umlinganiselo we-HPMC ukuba kuyimfuneko ngokusekelwe kwi-performanc ephawulweyo
