Hydroxyethyl methyl selulose (HEMC) ni iki?
Hydroxyethyl methylcellulose(HEMC) izwi kandi nka methylhydroxyethyl selulose (MHEC). Nibintu byera, byera byera, cyangwa umuhondo wera. Nibintu bitari ionic selulose ether yabonetse mukongeramo okiside ya Ethylene kuri methyl selulose. Ikozwe muri polimeri isanzwe ishobora kuvugururwa nkibiti byimbaho cyangwa ipamba, kandi HEMC irashobora gukoreshwa nkumukozi wo kubika amazi meza cyane, imashini ifata amashusho, stabilisateur, nibindi. Ikoreshwa cyane mubikorwa bitandukanye byinganda, nkamavuta gucukura, kubaka no kubaka, gusiga amarangi no gutwikira, imiti, nibindiHEMCIrashobora guhindurwa ukurikije ibyo umukiriya asabwa, kandi nyuma yo guhinduka, iracyafite imbaraga zo kurwanya kugabanuka no gutunganywa neza. Ushaka gukoreshaHEMChagamijwe inganda? Nyamuneka hamagara uwatanze isoko yizewehydroxyethyl methyl selulosekubona ibikorwa byiza.
HEMCifite imirimo itandukanye. Harimo:
1. Kugaragara
HEMCirashobora kuba umweru, umuhondo werurutse, umuhondo wera, cyangwa umweru.
2. Gukemura
HEMCirashonga mumazi (imbeho cyangwa ubushyuhe). NubwoHEMCntigishobora gukemuka mumashanyarazi menshi, irashobora gushonga mumyanya ibiri ya organic organique hamwe na sisitemu yamazi yumuti.
Ubwinshi bwacyo buterwa nubwiza, kandi gukomera kwayo biratandukanye nubwiza. Hasi ya viscosity, niko gukomera, nibindi.
3. Guhagarara kwa pH
HEMCihamye murwego rwa 3.0-11.0 kandi ubwiza bwayo ntaho butaniye, ariko kurenza iyi ntera bizagabanya ubukonje bwayo.
4. Metabolism
HEMCni inert ikoreshwa cyane mubiribwa nubuvuzi kubera ko idashobora kwandura metabolism.
5. Igikorwa cyo hejuru
Bitewe nubuso bwacyo bukora mubisubizo byamazi, irashobora gukoreshwa nkikwirakwiza, ikingira, na emulifier.
6. Kurwanya ibihumyo
Mububiko bwigihe kirekire,HEMCifite ubwiza bwimitekerereze myiza, kubwibyo ifite uburyo bwiza bwo guhangana.
Ubushobozi bwayo bwo kurwanya mold burenze ubwa hydroxyethyl selulose.
Kubika amazi
HEMCihinduka uburyo bwiza bwo kubika amazi kubera ubwiza bwayo bwinshi mubisubizo byamazi.
Ubushobozi bwo gufata amazi buruta ubwa methyl selulose.
8. Ibirimo ivu
Gahunda yo kwitegura yaHEMCikoresha amazi ashyushye yoza, bivamo ivu rike cyane.
9. Amashanyarazi yumuriro
IyoHEMCigisubizo gishyushye kubushyuhe runaka, transparency yayo iragabanuka, ikora imyanda na gel, ariko iyo ikonje, izasubira muburyo bwambere bwigisubizo.
Ikoreshwa rusange ryaHEMC
Hydroxyethylmethylcelluloseirashobora gukoreshwa nka:
Hes AdhesiveØ Kurinda colloidØ ThickenerØ Umukozi ukora firime Emulsifier LubricantØ Umukozi uhagarika
Inganda zikoreshwa mu nganda zaHEMC
HEMCikoreshwa cyane mu nganda zikurikira:
· Guteranya · Ubukorikori · Amavuta yo kwisiga · Ubwubatsi · Ibiribwa n'ibinyobwa · Imiti · Irangi hamwe na Coatings · Gucukura inkwa hamwe namavuta
Nkuko byavuzwe haruguru,hydroxyethyl methylcellulose (HEMC) ni inkomoko ya methylcellulose. Nibikoresho bya ionic selulose ether bikozwe mubikoresho byiza byipamba.HEMC'kubika amazi nubushobozi bwo kubyibuha bituma bikwiranye namazi ashingiye kumazi ya latx, wino no gucukura peteroli, ibikoresho byubwubatsi, nibindi. Kubera gukoreshwa kwinshi mubikorwa bitandukanye, kubonaHEMCuhereye kubatanga bazwi cyane ba hydroxyethyl methyl selulose irashobora kwemeza ko ubona ibicuruzwa bibereye gukoreshwa kugiti cyawe cyangwa inganda.
