Ethyl cellulose

Ethyl cellulose inobva kune cellulose, yakasikwa polymer inowanikwa mumiti. Iyo inogadzirwa kuburikidza nekuita kwe cellulose ne ethyl chloride pamberi peiyo catalyst. Ethyl cellulose inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kweiyo yakasarudzika zvivakwa uye kuita zvakasiyana. Heano mamwe akakosha maitiro uye mashandisiro ethyl cellulose:

1. Insolubility muMvura: Ethyl cellulose haina kunyungudika mumvura, izvo zvinoita kuti ive yakakodzera kune maapplication panodiwa kudzivirira mvura. Ichi chivakwa chinobvumirawo kushandiswa kwayo sechidziviriro chekudzivirira mumishonga uye sechinhu chinovharira mukutakura chikafu.
2. Solubility muOrganic Solvents: Ethyl cellulose inonyungudika mune dzakasiyana siyana organic solvents, kusanganisira ethanol, acetone, uye chloroform. Kunyungudika uku kunoita kuti zvive nyore kugadzira uye kugadzira muzvigadzirwa zvakasiyana-siyana, semajasi, mafirimu, uye ingi.
3. Firimu-Kugadzira Mano: Ethyl cellulose inokwanisa kuumba anochinjika uye akasimba mafirimu pakuomeswa. Ichi chivakwa chinoshandiswa mumashandisirwo akadai semahwendefa ekuputira mumishonga, uko inopa inodzivirira layer kune inoshanda zvinongedzo.
4. Thermoplasticity: Ethyl cellulose inoratidza hunhu hwe thermoplastic, zvichireva kuti inogona kupfaviswa nekuumbwa kana yapiswa uye yobva yasimba pakutonhodza. Ichi chivakwa chinoita kuti ive yakakodzera kushandiswa mukupisa-kunyunguduka kunamira uye mapurasitiki anoumbwa.
5. Kemikari Inertness: Ethyl cellulose ikemikari inert uye inoshingirira kune acids, alkalis, uye yakawanda organic solvents. Ichi chivakwa chinoita kuti ive yakakodzera kushandiswa mukuumbwa uko kugadzikana uye kuenderana nezvimwe zvinhu zvakakosha.
6. Biocompatibility: Ethyl cellulose inowanzoonekwa seyakachengeteka (GRAS) yekushandisa mumishonga, chikafu, uye zvigadzirwa zvekuzora. Iyo isiri-chepfu uye haina kuisa njodzi yemhedzisiro yakaipa kana ichishandiswa sezvainoda.
7. Kusunungurwa Kunodzorwa: Ethyl cellulose inowanzoshandiswa mukugadzirwa kwemishonga kudzora kusunungurwa kwezvinhu zvinoshanda. Nekugadzirisa ukobvu hweiyo ethyl cellulose coating pamapiritsi kana pellets, chiyero chekuburitswa kwezvinodhaka chinogona kugadziridzwa kuti chiwane akawedzera kana akasimba kuburitswa profiles.
8. Binder uye Thickener: Ethyl cellulose inoshandiswa sebhainda uye gobvu mumashandisirwo akasiyana siyana, anosanganisira ingi, machira, uye zvinonamira. Iyo inovandudza iyo rheological zvimiro zvekuumbwa uye inobatsira kuwana inodiwa kuenderana uye viscosity.

ethyl cellulose i polymer inoshanda zvakasiyana-siyana ine huwandu hwakawanda hwekushandisa mumaindasitiri akadai semishonga, chikafu, zvekuzora, machira, uye zvinonamira. Kusanganiswa kwayo kwakasarudzika kwezvivakwa kunoita kuti ive chinhu chakakosha mumigadziriso yakawanda, uko inobatsira kugadzikana, kuita, uye kushanda.
