Cellulose ether

Cellulose etherMhando yemheremalose inobviswa iyo inogadziriswa nemakemikisirwo kuti uwedzere kuwedzeredza zvivakwa zvaro uye uiite zvakanyanyisa kuita zvakasiyana siyana zvehuwandu hwekushandisa maindasitiri. Iyo inotorwa kubva ku cellulose, iyo ndiyo yakanyanya kuwanda polymer inowanikwa mumasero emaruva ezvirimwa. Cellulose ether inogadzirwa nekubata cellulose nemacemical reagents kusuma mapoka ekutsiva kune iyo cellulose Molecule, zvichikonzera kuvandudzwa, uye kuita uye kushanda. Heano mamwe mapoinzi akakosha nezve cellulose ether:

1. Chemical chimiro:

• Cellulose ether yekukoshesa cellucose chimiro, icho chine kudzokorora zvikamu zveGlucose zvakabatanidzwa pamwechete ne β (1 → 4) Glycosic Zvisungo.
• Kumakemikari kugadziridzwa kunounza mapoka emapoka, akadai se methyl, ethyl, hydroxyprichyl, cardroyropyl, uye vamwe, kuHydroxyl (-oh) mapoka emherulose molecule.

2. Zvivakwa:

• Solubility: Cellulose anainhers inogona kuvezwa kana kuparadzaniswa mumvura, zvichienderana nerudzi uye degree rekutsiva. Iyi solubility inovaita yakakodzera kushandiswa mune mafomu ezvekumuka.
• Rheology: Cellulose ana mhereter vanoita sevanoshanda, renhema modifiers, uye stabilizers mune zvemvura mafomu, kupa viscosity kudzora uye kugadzirisa chigadzirwa kugadzikana uye kuita.
• Firimu-inogadzira: Mamwe ma cellulose ethema-emafirimu ekugadzira firimu, achivabvumira kugadzira mafirimu akaonda, anochinjika kana akaomeswa. Izvi zvinovaita kuti vabatsire mujasi, zvinonamatira, uye zvimwe zvinoshandiswa.
• Kugadzikana: Cellulose ana ana anairatidzira kuratidzira kugadzikana pamusoro pehuremu hwakasiyana-siyana hwemamiriro ekunze, uchiita kuti vakwanise kushandiswa mukushandiswa kwakasiyana siyana.

3. Mhando dze Cellulose Ether:

• Methylcellose (mc)
• Hydroxyprupyl methylcellose (HPMC)
• HydroxytHyl Cellulose (Hec)
• Carboxymethyl cellose (cmc)
• Ethyl hydroxyll cellulose (ehec)
• Hydroxyprupyl cellulose (HPC)
• Hydroxytlyl methylcellose (hemc)
• Sodium CarboxyMethyl Cellulose (Nacmc)

4. Zvikumbiro:

• Kuvaka: Inoshandiswa seVatongi, Vamiriri vemvura, uye rheology modifiers mune zvigadzirwa-zvakavakirwa zvigadzirwa, pendi, majasi, uye anomiririra.
• Kuchengeta Kwemunhu uye Cosmetics: Working Sirizi, Stabilizers, mafirimu akanyorwa, uye emlsifiers mumarara, Shampoos, uye zvimwe zvigadzirwa zvemunhu zvega.
• Mishonga: Inoshandiswa seBinders, disintegraphts, dzakadzorwa-dzakaburitswa-vamiririri, uye vhiza modifizi mukugadzira piritsi, kumiswa, mafuta, uye zvigunwe zvemusoro.
• Chikafu uye Zvinwiwa: Kushandiswa senhau, Stabilizers, emulsifiers, uye modifiers mune zvigadzirwa zvekudya, zvipfeko, zvigadzirwa zveDairy, uye zvinwiwa.

5. Kudenga:

• Cellulose ana ana vana anotorwa kubva kune inovandudzwa masango-inozvidza zvinyorwa, kuita ivo varipiresi dzimwe nyika dzimwe nzira dzevashandi vekuSynthetic.
• Ivo vane biozuriki uye havaite mupfuurire mukusvibiswa kwezvakatipoteredza.

Mhedziso:

Cellulose ether inzvimbo inoverengeka uye ine nzvimbo yakasimba ine huwandu hwakawanda hwekushandisa mumaindasitiri akadai sekuvaka, kutarisirwa kwega, mishonga, uye chikafu. Zvivakwa zvaro zvakasarudzika uye zvinoshanda zvinoita kuti ive yakakosha mune zvakawanda zvekuumbwa, zvinobatsira kuita zvigadzirwa, kugadzikana, uye hunhu. Maindasitiri anoramba achiisa pekutsigira uye eco-oushamwari mhinduro, kudikanwa kwemasero anotarisirwa kukura, kutyaira mune ino ndima.
