Yintoni i-hydroxyethyl methyl cellulose (HEMC)?
I-Hydroxyethyl methylcellulose(HEMCIkwaziwa njenge methylhydroxyethyl cellulose (I-MHEC).Lisuntswana elimhlophe, elingwevu, okanye elimthubi.Yi-non-ionic cellulose ether efunyenwe ngokudibanisa i-ethylene oxide kwi-methyl cellulose.Yenziwe kwiipolymers zendalo ezihlaziyiweyo ezifana ne-pulp yomthi okanye ikotoni, kwaye i-HEMC ingasetyenziselwa njenge-agent ephezulu yokugcina amanzi, i-adhesive kunye ne-agent yefilimu yokwenza ifilimu, i-stabilizer, njl. Isetyenziswa ngokubanzi kwizicelo ezahlukeneyo zoshishino, njengeoli. ukugrumba, ukwakhiwa kunye nokwakhiwa, ipeyinti kunye neengubo, amayeza, njl.HEMCinokuguqulwa ngokweemfuno zabathengi, kwaye emva kohlengahlengiso, isenokumelana okuhle nokuncipha kunye nokusebenza kakuhle.Ufuna ukusebenzisaHEMCngeenjongo zoshishino?Nceda uqhagamshelane nomthengisi othembekileyo wei-hydroxyethyl methyl celluloseukufumana intengiselwano elungileyo.
HEMCinemisebenzi eyahlukeneyo.Ziquka:
1. Imbonakalo
HEMCinokuba mhlophe, tyheli ngokukhanyayo, mhlophe tyheli, okanye ingwevu emhlophe.
2. Ukunyibilika
HEMCiyanyibilika emanzini (ibanda okanye ishushu).NangonaHEMCayinyibiliki kuninzi lwezinyibilikisi eziphilayo, iyanyibilika kwizinyibilikisi eziphilileyo zokubini kunye neenkqubo zamanzi ezinyibilikayo zendalo.
Ukugxininiswa kwayo okuphezulu kuxhomekeke kwi-viscosity, kwaye ukunyibilika kwayo kuyahluka kunye ne-viscosity.I-viscosity ephantsi, i-solubility enkulu, kunye ne-vice versa.
3. Ukuzinza kwe-pH
HEMCuzinzile kuluhlu lwe-3.0-11.0 kwaye i-viscosity yayo iphantse ingachaphazeleki, kodwa ukudlula olu luhlu kuya kunciphisa i-viscosity yayo.
4. Imetabolism
HEMCyinto engasebenziyo esetyenziswa kakhulu ekutyeni nakwiyeza ngenxa yokungakwazi kwayo ukungena kwimetabolism.
5. Umsebenzi womphezulu
Ngenxa yomsebenzi wayo osebenzayo kwizisombululo ezinamanzi, inokusetyenziswa njenge-dispersant, umkhuseli, kunye ne-emulsifier.
6. Ukunganyangeki kwefungus
Kwindawo yokugcina ixesha elide,HEMCinozinzo oluhle lwe-viscosity, ngoko ke inokumelana nokungunda okulungileyo.
Ikhono layo lokulwa nokungunda liphezulu kuneselulosi ye-hydroxyethyl.
7. Ukugcinwa kwamanzi
HEMCiba yinto esebenzayo yokugcina amanzi ngenxa ye-viscosity yayo ephezulu kwizisombululo ezinamanzi.
Umthamo wayo wokugcina amanzi mkhulu kunowo we-methyl cellulose.
8. Umxholo wothuthu
Inkqubo yokulungiselelaHEMCisebenzisa ukuhlamba ngamanzi ashushu, okukhokelela kwisiqulatho sothuthu esisezantsi kakhulu.
9. I-adhesive conductive ye-thermal
Xa iHEMCisisombululo sifudunyezwa kwiqondo lokushisa elithile, ukucaca kwayo kuyancipha, ukwenza intlenga kunye nejel, kodwa ukuba ipholile, iya kubuyela kwimeko yokuqala yesisombululo.
Ukusetyenziswa okuqhelekileyo kweHEMC
I-Hydroxyethyl methylcelluloseingasetyenziswa njenge:
Ø I-AdhesiveØ I-colloid ekhuselayoØ I-ThickenerØ i-ejenti yokwenza ifilimu i-Emulsifier LubricantØ i-Agent yokuSuspension
Izicelo zamashishini zeHEMC
HEMCisetyenziswa kakhulu kula mashishini alandelayo:
·Aggregation·Ceramics · Cosmetics·Construction·Ukutya kunye nesiselo·Amayeza · Ipeyinti kunye ne Coatings · Ink kunye ne-oyile yokomba
Njengoko bekutshiwo ngaphambili,ihydroxyethyl methylcellulose (HEMC) iphuma kwimethylcellulose.Yi-ether engeyiyo ionic cellulose eyenziwe ngezixhobo zomqhaphu ezisulungekileyo.HEMCUgcino lwamanzi kunye nezakhono ezityebileyo zenza ukuba zilungele iipeyinti zelatex ezisekelwe emanzini, ii-inki kunye nokomba wepetroleum, izinto zokwakha, njl.njl. Ngenxa yokusetyenziswa kwayo ngokubanzi kwizicelo ezahlukeneyo, ukufumanaHEMCkubaboneleli abaziwayo be-hydroxyethyl methyl cellulose bangaqinisekisa ukuba ufumana iimveliso ezifanele ukusetyenziswa komntu okanye kwishishini.
