I-methyl hydroxyyethyl cellulose (Mhec) iyingxenye ebalulekile ye-cellulose ether ehlanganisa ukuguqulwa okubili kwe-methylation kanye ne-hydroxyethylation. Ezimbozweni ezisuselwa emanzini, uMhec udlala indima ebalulekile ngezakhiwo zayo ezihlukile zenyama nangamakhemikhali.
I. Izici Zokusebenza
Ukuqina
Amaqembu we-hydroxyethyl kanye ne-methyl ekwakhekeni kwamangqamuzana e-MHEC angakha isakhiwo senethiwekhi esikhaleni esinamanzi, ngaleyo ndlela andise ngempumelelo i-viscosity ye-coating. Lo mphumela wokuqina uvumela ukuthi ifinyelele ukufezekisa i-Rheology ekahle ngokugxila okuphansi, ngaleyo ndlela kunciphise inani lokuhlanganisa kanye nezindleko zokonga.
Ukulungiswa kwe-bhe
I-MHEC inganikeza ukuhlanganisa i-fluority enhle kanye nezakhiwo ezilwa nama-anti-sagging. Izici zalo ze-Pseudoplastic zenza ukuhlanganiswa kube nokuvunywa okuphezulu esimweni esiphakeme, futhi i-viscosity ingancishiswa ngesikhathi senqubo yokufaka isicelo, okulungele ukuxubha, ekugcineni kungabuyisela ngokushesha ukubonwa kwangempela ngemuva kokwakhiwa kuqediwe, kunciphisa i-sag noma ukudonsa.
Ukugcinwa kwamanzi
I-MHEC inezakhiwo ezinhle zokugcina amanzi futhi ingalawula ngempumelelo isilinganiso samanzi. Le mpahla ibaluleke kakhulu ukuvikela upende osuselwa emanzini kusuka ekuqhekekeni, i-powling kanye nezinye iziphambeko ngesikhathi senqubo yokomisa, futhi futhi ingathuthukisa ubushelelezi nobunye bokufana kwe-coating ngesikhathi sokwakha.
Ukuqina kwe-emulsion
Njenge-surving, i-MHEC inganciphisa ukungezwani kwezinhlayiya zezingulube kumapende asuselwa emanzini futhi kukhuthaze ukuhlakazeka kwabo okufanayo ezintweni ezifunwayo, ngaleyo ndlela kuthuthukiswe ukuqina kanye nokugwema ukupenda kanye nemvula yopende.
Biodegradeability
I-MHEC isuselwa ku-cellulose yemvelo futhi ine-biodegradadability enhle, eyenza ibe nezinzuzo ezisobala kumapende asuselwa kumanzi emvelweni futhi isiza ukunciphisa ukungcoliswa kwemvelo.
2. Imisebenzi eyinhloko
Kukhulu
I-MHEC isetshenziswa ikakhulukazi njenge-nyouner for upende osuselwa emanzini ukuthuthukisa ukusebenza kwayo kokwakha kanye nekhwalithi yefilimu ngokwandisa i-viscosity yopende. Isibonelo, ukungeza i-MHEC kupende we-latex kungakha umfaniswano ofanayo odongeni ukuvikela upende kusuka ku-sagging ne-sag.
Umlawuli we-Rheology
I-MHEC ingaguqula i-rheology yamapende asuselwa emanzini ukuze aqinisekise ukuthi kulula ukuyisebenzisa ngesikhathi sokwakha futhi angasheshe abuyele esimweni esizinzile. Ngalesi silawuli seRherological, i-Mhec ngempumelelo ithuthukisa ukusebenza kwezokwakha zokuhlanganiswa, okwenza kube lulungele izinqubo ezahlukahlukene zokuhlanganisa.
I-ejenti yokugcina amanzi
Ezimbozweni ezisuselwa emanzini, impahla egciniwe yamanzi ye-MHEC isiza ukwandisa isikhathi sokuhlala samanzi ku-coating, ithuthukise ukufana kokomisa kwama-coating, futhi ivikele isizukulwane semifantu kanye neziphene ezingaphezulu.
Isitabili
Ngenxa yekhono layo elihle le-emulsuncication, i-MHEC ingasiza ama-coating asuselwa emanzini akha uhlelo oluzinzile lwe-emulsion, agweme ukuhanjiswa kwemvula kanye nokwenza ngcono izinhlayiya ze-pigment, futhi kuthuthukise ukuqina kwesitoreji kwenhlanganisela.
Usizo Olwenziwe Film
Ngesikhathi senqubo eyakha amafilimu ye-coating, ukuba khona kwe-MHEC kungakhuthaza ukufana nokubusheleleka kokuhlanganiswa, ukuze ukuhlanganiswa kokugcina kunokubukeka okuhle nokusebenza.
3. Izibonelo zohlelo lokusebenza
I-Latex Paint
Ku-Latex Paint, umsebenzi oyinhloko we-MHEC ukuqina nokugcinwa kwamanzi. Kungathuthukisa kakhulu ukuxubha kanye nokugoqa izakhiwo zopende we-latex, futhi kuqinisekiswe ukuthi ukuhlanganiswa kugcina bushelelezi obuhle nokufana ngesikhathi senqubo yokomisa. Ngaphezu kwalokho, i-MHEC nayo ingakhulisa ukuphinda i-anti-splashering kanye ne-sagging Properties ye-latex Paint, okwenza inqubo yokwakha ibushelelezwe.
Upende wezinkuni onomanzi
Ku-Waterborte Wood Paint, uMhec uthuthukisa ubushelelezi kanye nokufana kwefilimu yokupenda ngokulungisa i-viscosity kanye ne-rheology yopende. Kungavimba futhi upende kusuka ekwakheni i-sagging kanye nokuhamba ebusweni izinkuni, futhi uthuthukise umphumela wokuhlobisa nokuqina kwefilimu.
Upende Wokwakha Amanzi
Ukusetshenziswa kwe-MHEC kupende wokwakha amanzi kungathuthukisa ukusebenza kokwakha kanye nekhwalithi yopende, ikakhulukazi lapho izindawo ezinamakhanda ezinjengezindonga nophahla, kungavimba ngempumelelo ukugcwala nokudonsa ngopende. Ngaphezu kwalokho, impahla yokugcinwa kwamanzi ye-MHEC nayo inganweba isikhathi sokusoma sopende, sinciphise ukuqhekeka kanye neziphene ezingaphezulu.
Upende Wezimboni Wezimboni
Ku-Waterborne Wezimboni Upende, i-Mhec ayisebenzi kuphela njenge-ejenti yabakhulu kanye ne-ejenti yokugcina amanzi, kodwa futhi ithuthukisa ukuhlakazwa kanye nokuqina kopende, ukuze upende lukwazi ukuqina kokuqina nokuqina ezindaweni eziyinkimbinkimbi zezimboni.
IV. Amathemba emakethe
Ngemithetho yokuvikelwa kwemvelo eqhubekayo eqinile kanye nesidingo esandayo sezinto zokwakha eziluhlaza, isidingo semakethe sokupenda ngamanzi siyaqhubeka sikhula. Njengesengezo esibalulekile kuPaintte Waterrne Paints, i-MHEC inamathuba abanzi emakethe.
Ukunyuswa kwenqubomgomo yezemvelo
Emhlabeni jikelele, izinqubomgomo zezemvelo ziye zaqinisa kakhulu imikhawulo kuma-turatile organic compact compact compound compact (VOC), okuye kwathuthukisa ukusetshenziswa kwezingubo zokumbona ezibodwa. Njengesengezo esinobungani bemvelo, iMhec idlala indima ebalulekile embonweni wamanzi, futhi ukufunwa kwayo kuzokwanda nokwanda kwemakethe ye-Waterborne Coatings.
Ukufunwa okukhulayo embonini yezokwakha
Isidingo esandayo se-Low-Voc, izigqoko zokusebenza okuphezulu embonini yezokwakha nazo zigqugquzele ukusetshenziswa kwe-MHEC eqeshini sokwakha amanzi. Ikakhulu ezembozo zodonga lwangaphakathi nangaphandle, i-MHHEC inganikeza ukusebenza okuhle kokwakha nokuqina ukuze kuhlangatshezwane nokufunwa kwemakethe.
Ukunwebeka ukusetshenziswa kwezimbozo zezimboni
Isidingo esikhulayo sezimbali ezinobungane kwemvelo ensimini yezimboni nazo zigqugquzele ukusetshenziswa kwe-MHEC ekugqokeni kwezimboni ezibomvana. Njengoba izigqoko zezimboni zikhula zibheke ezinkomba ezinobungane nezemvelo, i-MHEC izodlala indima ebonakalayo ekuthuthukiseni ukusebenza kwezixhumanisi kanye nezimpawu zezemvelo.
I-methyl hydroxyyethyl cellulose (Mhec) idlala indima ebalulekile ekuboleni kwamanzi okubandakanyeka ngamanzi ngokuqina kwayo okuhle, ukulungiswa kwama-bheology, ukugcinwa kwamanzi, ukuqina kwe-emulsion kanye ne-bioderghabilibility. Ukusetshenziswa kwayo ekugqokeni okususelwa emanzini akugcini nje ngokuthuthukisa ukusebenza kwezokwakha kanye nekhwalithi ye-coatings, kepha futhi kuvumelana nokwenza okuvikelekile kwemvelo kanye nentuthuko esimeme. Ngesidingo esikhulayo semakethe sokusebenza okuphezulu, izimbangi eziphansi ezisuselwa emanzini, amathemba wesicelo se-MHEC kule nkambu azoba abanzi.
