I-Methylhydroxyethylcellulose (MHEC) iyi-ether ye-cellulose ebalulekile esetshenziswe kabanzi embonini yezokwakha ngenxa yezakhiwo zayo ezinhle kakhulu. Isakhiwo esiyisisekelo se-MHEC ukwethulwa kwamaqembu e-methyl kanye ne-hydroxyethyl ku-cellulose skeleton, eguqulwa ngamakhemikhali ukuze ibe nezindawo eziyingqayizivele, ezifana nokuqina, ukugcinwa kwamanzi, ukunamathela kanye nokwakheka kwefilimu.
ukuqina umphumela
I-MHEC inomphumela omuhle wokuqina futhi ingakhuphula ngokuphawulekayo i-viscosity yodaka kanye nezingubo. Ekwakhiweni, i-viscosity yodaka ithinta ngokuqondile ukusebenza kwayo kokwakhiwa kanye nomphumela wokugcina. Ngokwandisa i-viscosity yodaka, i-MHEC yenza kube lula ukucwila lapho isetshenziswa futhi ingamboza udonga ngokulinganayo, ithuthukise ukusebenza kahle kokwakhiwa kanye nekhwalithi. Ukwengeza, ukwengeza i-MHEC ekugqokeni kungavimbela ukugoqa ekugwemeni nasekushayeni, kuqinisekiswe ukufana nokushelela kwengubo.
ukugcinwa kwamanzi
Ukugcinwa kwamanzi kungenye yezakhiwo ezibaluleke kakhulu ze-MHEC ezintweni zokwakha. Phakathi nenqubo yokwakha, umswakama odakeni nokhonkolo uyancipha ngokushesha ngenxa yokuhwamuka nokumuncwa, okuholela ekulahlekelweni kwamandla ezinto ezibonakalayo nokuqhekeka. I-MHEC ingakwazi ukugcina amanzi ngokuphumelelayo, yandise isikhathi sokumanzisa udaka nokhonkolo, ikhuthaze i-hydration eyanele kasimende, futhi ithuthukise amandla nokuqina kwezinto ezibonakalayo. Ikakhulukazi ezindaweni zokwakha ezisezingeni eliphezulu noma ezomile, umsebenzi wokugcina amanzi we-MHEC ubaluleke kakhulu.
ukuhlanganisa
I-MHEC futhi inezakhiwo ezinhle kakhulu zokuhlanganisa futhi ingathuthukisa amandla okubopha phakathi kodaka ne-substrate. Kuzinto zokunamathela zamathayili nezinhlelo zokuvikela odongeni zangaphandle, i-MHEC njengesithasiselo ingathuthukisa amandla okubopha okunamathelayo futhi ivimbele amathayela ukuthi angawi kanye nongqimba lokufakwayo ekuqhekekeni. Ngokusebenzisa i-MHEC ngokuhlakanipha ekubunjweni, ukwethembeka nokuphila isikhathi eside kwezinto zokwakha kungaqinisekiswa.
ukwakheka kwefilimu
I-MHEC inezinto ezinhle zokwenza ifilimu futhi ingakha ifilimu yokuzivikela efanayo phezulu. Le filimu evikelayo ivimbela umswakama ekuhwamukeni ngokushesha futhi inciphisa imifantu kanye nokuncipha ebusweni bento. Ezingxenyeni ezingangeni manzi nezinto zokuvala, umphumela wokwenza ifilimu we-MHEC ungathuthukisa ukusebenza okungangeni kwamanzi kwento futhi uqinisekise umphumela wokungangeni kwamanzi wesakhiwo. Ezitezi ezizilinganisa, i-MHEC ingaphinde ithuthukise ukushelela nokuthambile kwendawo yaphansi futhi inikeze imiphumela yokuhlobisa yekhwalithi ephezulu.
Eminye imisebenzi
Ngaphezu kwezindima eziyinhloko ezingenhla, i-MHEC inezinye izinhlelo zokusebenza ezibalulekile kumaphrojekthi wokwakha. Isibonelo, ukwengeza i-MHEC ukufafaza i-gypsum kungathuthukisa ukusebenza kokwakhiwa kanye nokushelela kwendawo ye-gypsum. Ku-putty yangaphandle yodonga, i-MHEC ingathuthukisa ukuguquguquka nokunamathela kwe-putty futhi ivimbele ukuqhekeka nokuwa. Ngaphezu kwalokho, i-MHEC ingasetshenziswa njengesiqinisi ukuvimbela ukubola kanye nemvula yezinto zokwakha ngesikhathi sokugcinwa, ukuqinisekisa ukuzinza nokufana kwezinto.
Izinhlelo zokusebenza
I-adhesive ye-tile: Ukwengeza i-MHEC ku-adhesive tile kungandisa isikhathi sokuvula kanye nesikhathi sokulungiswa kwe-adhesive tile, okwenza ukwakhiwa kube lula, kuyilapho kuthuthukisa amandla okubopha futhi kuvimbela amathayili ukuba angawi.
Isistimu yokufaka udonga yangaphandle: I-MHEC njengesithasiselo ingathuthukisa ukunamathela nokugcinwa kwamanzi kodaka lokufakelwa futhi ithuthukise ikhwalithi yokwakha nokuqina kwesendlalelo sokufakelwa.
I-self-leveling floor: Ukwengeza i-MHEC ezintweni ezizilinganisa phansi kungathuthukisa ukugeleza nokushaya phansi kwephansi futhi kuqinisekise ukushelela nobuhle bendawo yaphansi.
Ukugqoka okungangeni manzi: Ukusetshenziswa kwe-MHEC ekuhlanganiseni okungangeni manzi kungathuthukisa ukwakheka kwefilimu nokusebenza okungangeni kwamanzi kwentokozo futhi kuvimbele ukungena komswakama kanye nokulimala kwezinto.
I-Methylhydroxyethylcellulose isetshenziswa kabanzi kumaphrojekthi wokwakha ngenxa yokuguquguquka kwayo kanye nezakhiwo ezinhle kakhulu. Kusukela ekuqinisweni, ukugcinwa kwamanzi, ukubopha ekubunjweni kwefilimu, i-MHEC idlala indima ebalulekile ekuthuthukiseni ukusebenza kokwakhiwa kanye nomphumela wokugcina wezinto zokwakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokujula kocwaningo lwezicelo, amathemba okufaka isicelo se-MHEC emkhakheni wokwakha azoba banzi.
