IBanga Lokwakha Inhlanganisela Yokuzilinganisa ye-HPMC

I-HPMC, noma i-Hydroxypropyl Methylcellulose, i-ether ye-cellulose esetshenziswa kakhulu embonini yezokwakha. Ivame ukusetshenziswa njengesengezo kumakhompiyutha azilinganisa, okuyizinto ezisetshenziselwa ukubeka izinga lephansi elingalingani noma ukudala indawo ebushelelezi kwezinye izinto zokubeka phansi.

Izinhlanganisela zokuzilinganisa zivame ukusetshenziswa kumaphrojekthi wokwakha ukulinganisa phansi okungalingani noma okunamabala aphansi. Lezi zinhlanganisela ngokuvamile zenziwa ngengxube kasimende, isihlabathi, nezinye izinto, futhi zixutshwa namanzi ukuze kwakhiwe uketshezi oluthululwayo. Uma isithelwe phansi, inhlanganisela yokuzilinganisa iyageleza ukuze yakhe indawo ebushelelezi, esezingeni.

I-HPMC ivamise ukungezwa kumakhompiyutha okuzilinganisa ukuze kuthuthukiswe ukusebenza kwawo. Ikakhulukazi, kusiza ukuthuthukisa ukusebenza kwe-compound, okwenza kube lula ukuthulula nokusabalalisa ngokulinganayo. Kuyasiza futhi ekunciphiseni ukuncipha nokuqhekeka phakathi nenqubo yokomisa, futhi kungathuthukisa amandla esibopho phakathi kwenhlanganisela kanye ne-substrate engaphansi.

I-HPMC yebanga lokwakha iwuhlobo oluthile lwe-HPMC eklanyelwe ukusetshenziswa ezinhlelweni zokwakha. Ivamise ukusetshenziswa kuma-self-leveling compounds, nakwezinye izinto zokwakha ezifana nodaka, ama-grouts, nama-stuccos.

Izakhiwo ezithile zebanga lokwakha i-HPMC zingahluka ngokuya ngomkhiqizo kanye nomkhiqizi, kodwa ngokuvamile, inezici ezilandelayo:

Ukugcinwa kwamanzi okuphezulu: I-HPMC iwumthombo we-hydrophilic, okusho ukuthi inobudlelwane obuqinile bamanzi. Lesi sakhiwo sisiza ukuthuthukisa ukusebenza kwezinhlanganisela zokuzilinganisa, njengoba kusiza ukugcina ingxube imanzi futhi kulula ukusabalala.

Ikhono elihle lokwenza ifilimu: I-HPMC ingenza ifilimu elincanyana endaweni ehlanganisa ukuzilinganisa njengoba yoma, esiza ukuthuthukisa amandla ayo okusebenza nokuqina.

Ukunamathela okuthuthukisiwe: I-HPMC ingathuthukisa ukunamathela kwenhlanganisela yokuzilinganisa ku-substrate engaphansi, isize ukudala indawo eqinile, ehlala isikhathi eside.

Ukunciphisa nokuqhekeka: I-HPMC ingasiza ekunciphiseni inani lokushwabana nokuqhekeka okwenzeka phakathi nenqubo yokomisa, okungaholela endaweni elinganayo futhi ebushelelezi.

Ayinabuthi futhi ayihambisani nemvelo: I-HPMC iyimpahla engenabuthi, ehambisana nemvelo ephephile ukuthi isetshenziswe ezinhlelweni zokwakha.

Uma usebenzisa izinhlanganisela zokuzilinganisa eziqukethe i-HPMC yebanga lokwakha, kubalulekile ukulandela imiyalelo yomkhiqizi ngokucophelela. Ingxube kufanele ilungiswe ngokuhambisana nesilinganiso esinconyiwe samanzi-to-powder, futhi kufanele ixutshwe kahle ukuze kuqinisekiswe ukuthi i-HPMC isatshalaliswa ngokulinganayo kuyo yonke ingxube.

Uma i-self-leveling compound isithelwe phansi, kufanele isakazwe kusetshenziswa i-trowel noma elinye ithuluzi ukuze kwakhiwe indawo elinganayo. Kubalulekile ukusebenza ngokushesha, njengoba i-compound izoqala ukusetha phakathi nesikhathi esifushane.

Ngemva kokuba i-compound isisakaziwe, kufanele iyekwe ukuze yome isikhathi esinconywayo ngaphambi kokuba kufakwe noma yiziphi izinto ezengeziwe zokubeka phansi. Lokhu kuzosiza ukuqinisekisa ukuthi indawo engaphezulu yelaphekile futhi ilungele ukusetshenziswa.

Sekukonke, i-HPMC yebanga lokwakha iyinto ebalulekile embonini yezokwakha, ikakhulukazi ekuthuthukisweni kwezinhlanganisela zokuzilinganisa. Izici zayo eziyingqayizivele zisiza ukuthuthukisa ukusebenza kwalezi zinto, okwenza kube lula ukusebenza ngazo futhi zihlale isikhathi eside. Ngokusebenzisa izinhlanganisela zokuzilinganisa eziqukethe i-HPMC, ochwepheshe bezokwakha bangakha izindawo ezibushelelezi, ezisezingeni elifanele uhla olubanzi lwezinto zokwakha.
