HydroxytHyl methyl cellulose (hemc)Inoshamwaridzana yakakosha ether denderedzwa uye ndeya asiri-ionic cellulose ether. Hemc inowanikwa nemakemikari kugadziridzwa neyechivanhu cellulose seyakaisa zvinyorwa. Chimiro chayo chine hydroxylthyl uye methyl vakaderera, saka zvine akasiyana zvinhu uye zvemakemikari zvinoshandiswa mukuzvivaka, zvipuka, zvezuva nezuva, mushonga uye mamwe minda.
1. Zvepanyama uye zvemakemikari zvivakwa
Hemc inowanzo kuve chena kana kubva puru-chena poda kana granules, iyo inochema mumvura inotonhora kuti iite pachena kana zvishoma turbid colodal solution. Maitiro ayo makuru anosanganisira:
Solubility: Hemc inogona kunyungudika nekukurumidza mumvura inotonhora, asi ine isina kunaka solubility mumvura inopisa. Yayo solubility uye viscosity shanduko nekuchinja mukushisa uye pH kukosha.
Kuita kwakasimba: Hemc ine simba rakasimba rakasimba mumvura uye rinogona kuwedzera zvinowedzera zvevisiko zvemhinduro.
Kuchengeta mvura: Iyo ine yakanakisa yekuchengetedza mvura kuita uye inogona kudzivirira kurasikirwa kwemvura mune izvo zvinyorwa.
Firimu-inogadzira nzvimbo: hemc inogona kuumba yunifomu yeyakajeka firimu pane pamusoro pekunetseka uye kusimba.
Lubricity: Nekuda kweiyo yakasarudzika molecular chimiro, hemc inogona kupa yakanaka lubrication.
2. Kugadzira maitiro
Iyo yekugadzira maitiro yeHEMC inonyanya kusanganisira matanho anotevera:
Alkalization: Natural cellulose inobatwa pasi peAlkaline mamiriro ekugadzira Alkali cellulose.
Eteraifition Reaction: nekuwedzera methylating vamiririri (senge methyl chloride) uye hydroxylating vamiririri (senge ethylene oxide), cellylose oxidection
Kutumira-kurapwa: Iyo inokonzeresa chigadzirwa chisina kurapwa, kushambidzwa, akaomeswa, uye akapwanywa kuti apedzweHemczvigadzirwa.
3. Nzvimbo huru dzekushandisa
. Zvinogona kuvandudza zvevasikidzo, kuchengetedza kwemvura uye zvekunyepedzera-sagging zvivakwa zvekuvaka, kuwedzera nguva yakavhurika, uye nokudaro kunatsiridza kushanda kwekuvaka.
(2. Mukuwedzera, inogona kupa yakanaka firimu-yekuumba midziyo, ichigadzira iyo pendi pasi yakawanda yunifomu uye yakatsetseka.
. Nekuda kwekuchengetedza kwayo kwakakwirira uye kusanzwisisika, zvinowanzoshandiswa muzvigadzirwa zvakadai sekudonha kweziso, chechiso kuchenesa, uye marara.
.
4. Zvakanakira uye kuchengetedza zvakatipoteredza
Hemc ine yakakwira biodegradability uye yemamiriro ekunze ekudzivirira hunhu uye haazokonzeri kusvibiswa kwenguva refu kune zvakatipoteredza. Panguva imwecheteyo, haina chepfu uye chisina kukuvadza, chisina kukurumidza, kusatsamwisa kune ganda remunhu uye mucous membranes, uye anosangana nezvinodiwa zvekudzivirira zvakasvibirira zvezvakatipoteredza uye kusimba kwekuchengetedza.
5. Tarisiro yemusika uye maitiro ekuvandudza
Nekuvandudzwa kweindasitiri yekuvaka uye yezuva nezuva maindasitiri, musika unoda kuti hemc inoenderera ichikura. Mune ramangwana, sezvo vanhu vanoteerera zvakanyanya kune zvakatipoteredza zvinhu zvinoshamisa uye nekuwedzera kugadzirisa zvigadzirwa, hemc ichave yakashandiswa zvakanyanya muminda dzakasiyana siyana. Uye zvakare, kutsvagisa uye kusimudzira kwezvinhu zvitsva zvinoshanda zvigadzirwa (senge tembiricha yakanyanya kuramba uye inopisa mhando) ichakurudzira zvakare chikumbiro chacho mumusika wakakwira.
Sechivanhu chaunga uye chakakwirira-performan cellulose ether,hydroxytlyl methylcellose (hemc)inoita basa rakakosha mukuvaka, kuungana, mushonga uye mimwe minda ine zvimiro zvakasarudzika zvemuviri uye zvemakemikari. Nekufambira mberi kwesainzi uye tekinoroji uye kuwedzera kweminda yekushandisa, hemc ichatamba zvakanyanya indasitiri yemazuva ano uye ipe rutsigiro rwakasimba rwekuvandudzwa kwesindasitiri ane hukama.
