I-Hydroxypropyl methylcellulose (HPMC)iyi-ether engeyona ionic cellulose esetshenziswa kakhulu ezintweni zokwakha, ikakhulukazi odakeni oluxutshwe okomile. Udaka oluxutshwe okomile luyimpahla yesimanje yokwakha exuba ngaphambili izinhlobonhlobo zezinto ezingavuthiwe (ezifana nosimende, isihlabathi, izithasiselo nezithasiselo) ngesilinganiso esithile efektri. Uma isetshenziswa, idinga kuphela ukwengeza amanzi nokunyakazisa ukwakha. I-HPMC, njengesengezo esibalulekile, idlala indima engenakushintshwa odakeni oluxutshwe okomile, ithuthukise ukusebenza kahle kanye nokusebenza kahle kodaka lodaka.
1. Thuthukisa ukugcinwa kwamanzi futhi wandise isikhathi sokuvula
I-HPMC inezindawo ezinhle zokugcina amanzi. Phakathi nenqubo yokwakha, ingenza ifilimu encane odakeni, inciphise izinga lokuhwamuka kwamanzi, ukuze amanzi agcinwe odakeni isikhathi eside. Lesi sici sibaluleke kakhulu ekuphenduleni kwe-cement hydration, esiza ukuthuthukisa amandla nokunamathela kodaka futhi kugwenywe izinkinga zekhwalithi ezifana nokuqhekeka nokubhoboza okubangelwa ukulahlekelwa kwamanzi amaningi. Ngaphezu kwalokho, i-HPMC ingaphinda inwebe isikhathi esivulekile sodaka, inikeze abasebenzi bezokwakha isikhathi esengeziwe sokulungisa nokulungisa, futhi ithuthukise ukuguquguquka kwesakhiwo nokusebenza kahle.
2. Thuthukisa ukwakhiwa nokusebenza
I-HPMC inika udaka oluxutshwe okomile ukuvumelana okuhle nokushelela, okwenza kube lula ukulisebenzisa, bushelelezi kanye nekhalenda. Umphumela wawo wokuqina ungathuthukisa i-thixotropy yodaka, okwenza udaka lube uketshezi oluthe xaxa lapho lunyakaziswa noma kusetshenziswa amandla, futhi lungabuyisela ngokushesha ukuvumelana kwalo lapho lumile, okuzuzisa ukuzinza kwalo endaweni eqondile futhi kunciphisa ukugoqa. Emikhiqizweni eyahlukene yodaka oluxutshwe okomile efana nokunamathiswa kwamathayili, udaka lwe-plaster, nodaka lwaphansi, i-HPMC ingathuthukisa kakhulu ukusebenza kwayo kokwakhiwa, ngaleyo ndlela ithuthukise ukusebenza kahle kokwakhiwa kanye nekhwalithi yangaphezulu.
3. Thuthukisa ukusebenza kwesibopho
I-HPMC inomphumela obalulekile ekuthuthukiseni amandla okubopha odaka. Isakhiwo sayo samangqamuzana e-cellulose sinomsebenzi omuhle ongaphezulu, ongathuthukisa ukunamathela phakathi kodaka ne-substrate, futhi kuvimbele ukubola nokuvuleka. Emikhiqizweni efana ne-adhesive tile kanye ne-interface agent, ukungezwa kwe-HPMC kungaqinisekisa ukubopha okuqinile kwamathayela nama-substrates, kujwayelane nezinto ezihlukahlukene zamathayili nezinhlobo ze-substrate, futhi kuthuthukise amandla okubopha sekukonke nokuqina.
4. Thuthukisa i-anti-slip kanye nokugcinwa komumo
Ngesikhathi sokwakhiwa kodonga noma ukubeka amathayili, i-anti-slip iyinkomba ebalulekile. I-HPMC ingathuthukisa ikhono lokulwa nokushelela lodaka, ukuze isakwazi ukugcina indawo ezinzile lapho ibeka amathayela asindayo noma amatshe anosayizi omkhulu, ngaphandle kokushelela, futhi iqinisekise ikhwalithi yokwakha. Ngaphezu kwalokho, izakhiwo ezijiyayo ze-HPMC zingagcina kahle ukwakheka kodaka futhi zivikele ukucwila noma ukugeleza ngesikhathi sokwakhiwa kongqimba oluwugqinsi. Ifaneleka ngokukhethekile ukwakhiwa ezingxenyeni eziyinkimbinkimbi ezifana nama-facade nophahla.
5. Lungiselela ukuhambisana kwefomula futhi usebenzise kumasistimu ahlukahlukene we-dry-mix
I-HPMC inokuqina okuhle kwamakhemikhali kanye nohlu olubanzi lokuhambisana kwefomula, futhi ingasebenza ngezinto ezihlukahlukene ze-inorganic gelling kanye nama-emulsions e-polymer. Ilungele izinhlobonhlobo zezinhlelo ezifana ne-cement-based, i-gypsum-based, kanye ne-lime-based. Ayikwazi nje ukuzinzisa ukwakheka kwesistimu, kodwa futhi ithuthukise umphumela we-synergistic phakathi kwezingxenye ezihlukahlukene futhi ithuthukise ukusebenza okuphelele. Lokhu kuvumelana nezimo kukwenza kube esinye sezithasiselo ezisetshenziswa kakhulu nezithembekile kudaka lwengxube eyomile.
6. Thuthukisa ukumelana nokuqhekeka nokuqina
Ngenxa yomphumela wokugcina amanzi we-HPMC kanye nokwenza kahle kwe-microstructure of mortar, inganciphisa ngempumelelo izinkinga zokuqhekeka ezibangelwa ukuncipha noma ukungalingani kwe-hydration esigabeni sakamuva sokwakha, futhi ithuthukise ukumelana nokuqhekeka kodaka. Ngesikhathi esifanayo, ifilimu yokuzivikela ye-polymer eyakhiwe yiyo ingathuthukisa ukumelana nesithwathwa, ukumelana kwamanzi nokusebenza kokuguga kodaka ngezinga elithile, futhi yandise impilo yesevisi yezingxenye zokwakha.
7. Ukuvikelwa kwemvelo, ukuphepha, okungezona ubuthi nokungenabungozi
I-HPMC isuselwa emiculweni yezitshalo yemvelo futhi yenziwa ngemva kokuguqulwa kwamakhemikhali. Ine-biodegradability enhle kanye nobungane bemvelo. Ngeke ikhiphe amagesi ayingozi ngesikhathi isetshenziswa, ayinabo ubuthi futhi ayinabungozi kubasebenzi bokwakha, futhi ihambisana nomqondo wamanje wokwakha oluhlaza kanye nentuthuko esimeme.
Njengesengezo esibaluleke kakhulu sokusebenza okuphezulu kuudaka oluxutshwe owomile I-HPMCinendima ebalulekile ekugcineni amanzi, ukusebenza kokwakhiwa, ukunamathela, izakhiwo ezilwa nokushelela, njll., okungathuthukisi kuphela ukusebenza okuphelele kodaka oluxutshwe okomile, kodwa futhi kukhuthaza kakhulu ukumisa, ukwenziwa kwezimboni nokusebenza kahle kwezindlela zokwakha zesimanje. Njengoba izidingo zemboni yezokwakha zekhwalithi nokusebenza kahle ziqhubeka nokwanda, ukusetshenziswa kwe-HPMC kuzokwanda kakhulu, futhi ubuchwepheshe bayo nemikhiqizo kuzoqhubeka nokuthuthukiswa nokusungulwa, kufaka umfutho omkhulu embonini yezinto zokwakha.
