I-Methylhydroxyethylcellulose (MHEC) iyi-ether ye-cellulose esetshenziswa kabanzi ezimbonini ezihlukahlukene, kuhlanganise nomkhakha wokwakha nowokwakha. Ezingxenyeni zezakhiwo, i-MHEC iyi-thickener ebalulekile enikeza izakhiwo ezithile ekuhlanganiseni, ngaleyo ndlela ithuthukise ukusebenza kwayo.
Isingeniso se-Methyl Hydroxyethyl Cellulose (MHEC)
I-MHEC i-non-ionic cellulose ether etholakala ku-polymer cellulose yemvelo ngochungechunge lokuguqulwa kwamakhemikhali. Ibonakala ngenhlanganisela eyingqayizivele yamaqembu e-methyl kanye ne-hydroxyethyl enamathiselwe kumgogodla wayo we-cellulose. Lesi sakhiwo samangqamuzana sinikeza i-MHEC ukugcinwa kwamanzi okuhle kakhulu, ukuqina nokuqiniswa kwezakhiwo, okwenza kube kuhle ezinhlobonhlobo zezicelo embonini yezokwakha.
Izici ze-MHEC
1. Izakhiwo ze-Rheological
I-MHEC yaziwa ngezakhiwo zayo ezinhle kakhulu ze-rheological, ihlinzeka nge-viscosity efanelekile nezici zokugeleza zezingubo. Umphumela wokujiya ubalulekile ukuvimbela ukuwohloka nokuconsa ngesikhathi sokufaka isicelo futhi uqinisekise ukunamathela okulinganayo nokushelelayo.
2. Ukugcinwa kwamanzi
Esinye sezici ezibalulekile ze-MHEC amandla ayo okugcina amanzi. Lokhu kubaluleke kakhulu kuma-architectural coatings njengoba kusiza ukunweba isikhathi esivulekile sikapende, okuvumela ukulinganisa okungcono nokunciphisa amandla okomisa ngaphambi kwesikhathi.
3. Thuthukisa ukunamathela
I-MHEC ithuthukisa ukunamathela ngokuthuthukisa ukumanzisa kwendawo, iqinisekisa ukuthintana okungcono phakathi kokumboza ne-substrate. Lokhu kuthuthukisa ukunamathela, ukuqina kanye nokusebenza kwe-coating jikelele.
4. Ukuzinza
I-MHEC inika ukuzinza kwengubo, ivimbela izinkinga ezifana nokuxazulula nokuhlukaniswa kwesigaba. Lokhu kuqinisekisa ukuthi i-coating igcina ukufana kwayo kuyo yonke impilo yeshalofu nangesikhathi sokusetshenziswa.
Ukusetshenziswa kwe-MHEC ekugqokeni kwezakhiwo
1. Upende kanye ne-primer
I-MHEC isetshenziswa kabanzi ekwakhiweni kwamapende angaphakathi nangaphandle nama-primers. Izakhiwo zayo zokujiya zisiza ekwandiseni i-viscosity ye-coatings, okuholela ekuhlanganiseni okungcono nokusebenza okuthuthukisiwe kwesicelo. Umthamo wokubamba amanzi uqinisekisa ukuthi upende uzohlala usetshenziswa isikhathi eside.
2. I-textured coating
Ezembathweni ezenziwe ngombhalo, i-MHEC idlala indima ebalulekile ekuzuzeni ukuthungwa okufunayo. Izici zayo ze-rheological zisiza ngokulinganayo ukumisa ama-pigments nama-filler, okuholela ekuqedeni okungaguquki nokuthungwa ngokulinganayo.
3. I-Stucco kanye Nodaka
I-MHEC isetshenziselwa ukwakheka kwe-stucco nodaka ukuze kuthuthukiswe ukusebenza kahle nokunamathela. Izakhiwo zayo ezigcina amanzi zisiza ukwandisa isikhathi esivulekile, okuholela ekusetshenzisweni okungcono kanye nezakhiwo zokuqeda.
4. Ama-Sealants kanye namaCaulks
Izembatho zezakhiwo ezifana nama-sealants kanye ne-caulk ziyazuza ezicini ezishubile ze-MHEC. Kuyasiza ukulawula ukuvumelana kwalezi zakhiwo, ukuqinisekisa ukuvala nokuhlanganiswa okufanele.
Izinzuzo ze-MHEC ku-Architectural Coatings
1. Ukuvumelana nobunye
Ukusetshenziswa kwe-MHEC kuqinisekisa ukuthi izambatho zezakhiwo zigcina i-viscosity engaguquki futhi imbala, ngaleyo ndlela ikhuthaza ngisho nokusetshenziswa nokuhlanganisa.
2. Nweba amahora okuvula
Izakhiwo ezigcina amanzi ze-MHEC zinweba isikhathi esivulekile sikapende, zinikeza abadwebi nabafake izicelo isikhathi esengeziwe sokufaka isicelo esinembile.
3. Thuthukisa ukusebenza
Ku-stucco, udaka nezinye izimbotshana zezakhiwo, i-MHEC ithuthukisa ukusebenza kohlelo, ikwenze kube lula ngabafake izicelo ukufeza isiphetho abasifunayo.
4. Ukuqina okuthuthukisiwe
I-MHEC isiza ukuthuthukisa ukuqina kukonke kokunamathela ngokuthuthukisa ukunamathela nokuvimbela izinkinga ezinjengokwehla nokulungisa.
I-Methylhydroxyethylcellulose (MHEC) iwugqinsi olubalulekile embotsheni yezakhiwo ezinezakhiwo ezibalulekile ze-rheology kanye nokugcinwa kwamanzi. Umthelela wayo ekuvumelaneni, ukusebenza kanye nokuqina kwenza kube yisinqumo sokuqala ekwakhiweni kwamapende, ama-primers, ama-texture coatings, i-stucco, ama-mortars, ama-sealants kanye ne-caulk. Njengoba imboni yezokwakha iqhubeka nokuthuthuka, i-MHEC isalokhu iyingxenye eguquguqukayo nebalulekile ekuthuthukisweni kwezingubo zokugqoka ezisebenza kahle kakhulu.
