Ndeapi marudzi akasiyana e hydroxyethyl cellulose (Hec)?

HydroxytHyl Cellulose (Hec) ipurusi remvura-soluble polymer rakawanikwa nemakemikari kugadziridzwa kwemasikirwo emusango cellulose. Inoshandiswa zvakanyanya mumatombo, makemikari emazuva ese, zvinhu zvekuvaka uye mamwe minda. Mhando dzakasiyana dzeec dzinonyanya kutaurwa ne parameter dzakadai sedanho rekutsiva

1. Kugadziriswa ne degree rekutsiva

Dhigirii rekutsiva Shanduko muDS inokanganisa iyo solubility, viscosity uye nzvimbo dzekushandisa dzehasha.
Dhigirii rakaderera rekutsiva: DS iri pazasi 1.0. Dhigirii rakaderera rekutsiva hec ine yakaderera solubility uye inowanzoshandiswa munzvimbo dzinoda imwe nhanho yekukanganisika kwemvura, yakadai seyakagadzirwa uye zvimwe zvekuvakira.
Deadium degree rekutsiva Hec: ​​DS iri pakati pe1.0 uye 2.0. Rudzi urwu rwe hec ine yakanaka mvura solubility uye yakakwira viscosity, uye inowanzoshandiswa mune zvezuva nezuva zvigadzirwa (sekudzivirira uye cosmetics), kuungana uye embira.
Yakakwira degree rekutsiva yeHEC: DS iri pamusoro 2.0. Rudzi urwu rwe hec ine yakakwira mvura solubility uye inowanzoshandiswa mune zvekushandisa zvinoda kujeka kwepamusoro uye yakakwirira viscosity, yakadai seyeziso, mitezo yedutu mune yedanda rechikafu, nezvimwe.

2. Kugadziriswa nekutsiva kweMolar
Kutsiva kweMolar Iyo yakakwira iyo ms kukosha, iri nani iyo iyo solubility yemvura uye mwero wekupaza wehec kazhinji.
Low Molar Subindu Izvo zvakakodzera kuti zvikumbiro zvinoda kunonoka kushungurudzika kana kudzorwa kusunungurwa.
Pakati peMukati Kutsiva Hec: ​​MS iri pakati pe1 kusvika ku2
Yakakwira molar kutsiviwa kwehyoko: ms yakakura kupfuura 2

3. Kugadziriswa neViscosity
Iyo viscosity yehec chinhu chakakosha chiratidzo chehunhu hwayo mukugadzirisa, kazhinji zvichienderana nedunhu (kusungwa) kwemhinduro uye chiyero chemamiriro ezvinhu (senge shear rate).
Yakadzika viscosity hec: iyo viscosity mu 1% mhinduro iri pasi pe1000 MPA ·. Yakadzika viscosity hec yakakodzera kushandiswa seyekudzokorora masheya, anoparadzira uye anoshandiswa zvakanyanya mune zvezuva nezuva zvigadzirwa, indasitiri yechikafu, uye zvimwe gadziriso yemishonga.
Pakati pevaViscosity Hec: ​​Iyo viscosity mu 1% mhinduro iri pakati pe1000 uye 4000 MPA · Pakati pevaViscosity HEC inoshandiswa zvakanyanya mumatombo, kuomerera, kudhinda maindasitiri, uye nekuvakira maindasitiri, kupa maindasitiri akanaka, uye rheology kudzora.
Yakakwira viscosity hec: iyo viscosity mu 1% mhinduro yakakwira kupfuura 4000 MPA · High viscosity hec inonyanya kushandiswa seanotenderera uye stabilizer

4. Kugadziriswa nechigadzirwa chechigadzirwa
Hec inogona zvakare kuiswa zvinoenderana nechimiro chayo chemuviri, iyo inowanzoenderana nekushandisa kwayo uye kubata.
Yode yeLEC: Iyo inowanzozivikanwa fomu, iri nyore kutakura uye kuchengeta. Inoshandiswa mukuwanda kwemaindasitiri uye ezuva nezuva emakemikari, inoda kusanganisa mumvura kuti ugadzire mhinduro.
Granular Hec: ​​Granular Hec iri nyore kubata uye kunyungudika pane iyo hec yera, kudzora matambudziko eguruva uye akakodzera kugadzirwa kwemaindasitiri makuru.
Mhinduro

5. Special Inoshanda Hec
Kune zvakare mamwe mahekita ayo anga ari mamwe emakemikari akagadziridzwa kana kurapwa mumuviri kuti asangane nezvinodiwa zvechinyakare.
Crosslinked HEC: HEC yemvura yekudzivirira uye michina yemakwenzi inovandudzwa nekuyambuka kemikari kuyambuka, uye yakakodzera kanhi nguva dzinoda simba rakanyanya uye kusimba.
Yakagadziridzwa Hec: ​​Kuwedzera Kugadziridzwa (senge carboxymethylation, phosphorylation, etc.) inogadzirwa pahyokisheni yekupa mabasa mazhinji, sekuvandudzwa kwemidhara, kupisa kana kuderedza.
Yakasanganiswa Hec: ​​Yakatemerwa nedzimwe miti kana mashandiro ekushanda kuti azivise mashandiro azvo, sekushandiswa kweyakajaira mitezo mumatombo.

Semunhu akakosha emvura-solulable polymer. Kunzwisisa izvi zvikamu zvinobatsira kusarudza zvigadzirwa zvakakodzera ehec mune zvinoshanda zvekushandisa kuti uwane zvakanakisa kuita uye maitiro. Kunyangwe mumakemikari ezuva nezuva, zvigadzirwa zvekuvaka, hukudzo kana mushonga, hec hunoshandiswa zvakanyanya nekuda kwekunetseka kwayo kwakanaka, unyoro uye mafirimu-ekugadzira mafirimu.
