Application uye kugadzirira kwehydroxyethyl methyl cellulose hemc

HydroxytHyl methyl cellulose hemcInogona kushandiswa secloid inodzivirira mumiririri, emulsifier uye inopararira nekuda kweshoko rayo rekushanda rinoshanda mumhedzisiro mhinduro. Muenzaniso wekushandiswa kwayo ndewekutevera: Mhedzisiro yehydroxytHyl methyl cellelose pane zvivakwa zve simenti. Hydroxethyl methylcellose is a is is is is is is is is is is is is is is is is intoxy chena poda inodonha mumvura inotonhora kuti iite yakajeka, viscous solution. Iyo ine zvivakwa zvekuita, kusunga, kupararira, kupararira, kuumba-kuumba, kumhanyisa, kushambadzira, kusunga, kushandira unyoro uye kuchengetedza manyoro. Nekuda kwekushanda kwemvura inoshanda yemhinduro mhinduro, inogona kushandiswa seyakaganhurirwa inodzivirira mumiririri, elsififier uye anopararira. HydroxytHyl methyl cellalose Solution ine hydrophilicity ine hydrophilikuti
gadzirira
Nzira yekugadzirira hydroxythyl methyl cellel celleryl, iyo nzira inosanganisira ichishandisa yakanatswa machira seyakaomeswa uye ethylyone oxide seinowedzera mumiririri kugadzirirahydroxytHyl methyl cellelose. Izvo zvishandiso zvekugadzirira hydroxylyl methyl cellowl cell Yakanatswa Cotton, zvikamu makumi maviri nezvishanu zveOxyThane, 80-90 zvikamu zve methyl chloride, uye 16-19 zvikamu zve glacial acetic acid; Matanho chaiwo ndeiyi:

Nhanho yekutanga, muOntor, wedzera toluene uye isopropanol musanganiswa, mvura, uye sodium hydroxide, kuve nekudziya kusvika makumi matanhatu ~ 80 ℃, kuve yakawedzerwa 20 ~ maminitsi makumi mana;

Nhanho yechipiri, alkalization: inotonhorera zviri pamusoro apa kusvika pamakumi matatu ~ 50 Mamiriro ezvinhu anotevera: Nguva yeAlkalization ndeye maawa maviri, uye tembiricha yekudziya ndeye 30 ° ° C;

Nhanho yechitatu. Chikamu chekutanga chekutenderera: 40 ~ 60 ℃, 1.0 ~ 2,0 awa, dzvinyiriro inodzorwa pakati 0.150.3mpa; Chikamu chechipiri chekutsaukira: 60 ~ 90 ℃, 2.0 ~ maawa 2,5, kudzvinyirira kunodzorwa pakati pe 0.40.8mpa;

Nhanho yechina, kusarerekera: Wedzera metered blacial acetic acetsics yekusaona, kupisa 75 ~ 80 ℃ yekuita 102 68 When the precipitation is completed, the precipitation tank is filled with tap water treated by the reverse osmosis device at 90℃～100℃;

Nhanho yechishanu, iyo Centrifugal Washing: Zvinyorwa zviri muChifu Chechinguvana neChrewl Centrefugeruge, uye zvinhu zvakaparadzaniswa zvinoendeswa kune imwe nzvimbo yekushambidza yakazadzwa nemvura inopisa isati yasvika pamberi, uye zvinhu zvashambwa;

Nhanho yechitanhatu, Centrifugal Kuomesa: Chinyorwa chakashambwa chinotakurwa muChrew CentrefuGer Centrefuge

Tichienzanisa neiyo iripocellulose etherKugadzira tekinoroji, iyo iripo iripo inogamuchira Etlylone oxide kuti gadzirise gadziriso yekunyora metdroxyl metdroxose. Inogona kushandiswa pachinzvimbo chevamwe ma cellulose avaneta.
