Ethylcellulose inonzi multifunctional polymer inotorwa kubva ku cellulose kuburikidza nekuunza ethyl mapoka. Uku kugadziridzwa kunopa iyo polymer yakasarudzika zvivakwa, ichiita kuti ive yakakodzera kune akasiyana maindasitiri ekushandisa. Chinhu chakakosha chekushandisa ethylcellulose mundima dzakasiyana kunzwisisa maitiro ayo ekunyungudika sezvo ichikanganisa magadzirirwo ayo uye mashandisirwo.
Disolution nzira ye ethylcellulose:
Solubility properties:
Nekuda kweiyo hydrophobic hunhu hweiyo ethyl inotsiva, ethylcellulose inonyungudika zvishoma mumvura. Nekudaro, inoratidzira kunyungudika mune dzakasiyana siyana organic solvents, ichiita kuti ive yakakosha kune maapplication uko kushomeka kwemvura kwakakosha. Kazhinji zvinonyungudutsa zve ethylcellulose zvinosanganisira ethanol, ethyl acetate, methylene chloride, uye toluene. Iyo disolution process inosanganisira kutyora iyo intermolecular masimba mukati mepolymer, ichibvumira iyo solvent kuti ipinde uye kuparadzira cheni dzepolymer.
Zvinhu zvinokanganisa dissolution:
Zvinhu zvinoverengeka zvinokanganisa kupera kwe ethylcellulose:
Sarudzo yekunyungudutsa: Sarudzo yekunyungudutsa inoita basa rakakosha mukugadzirisa. Zvinonyungudutsa zvine hushamwari hwepamusoro hwe ethylcellulose, senge ethyl acetate, inomhanyisa kupera.
Tembiricha: Kuwedzera tembiricha kunowanzo wedzera chiyero chekunyungudika nekuti inopa simba rakawedzerwa rekubatana kwepolymer-solvent. Nekudaro, tembiricha yakawandisa inogona kukonzera kudzikira.
Saizi yepolymer particle: Idiki diki saizi inopa yakakura pamusoro penzvimbo yekusangana kwe solvent, zvichikonzera kukurumidza kupera. Kukuya kwakaringana kana particle size yekudzikisa matekiniki anogona kushandiswa kukwenenzvera kunyungudika.
Polymer Giredhi: Iyo giredhi yeethylcellulose inotarwa neiyo ethoxy yemukati uye molecular uremu, iyo inokanganisa kunyungudika kwayo. Yepamusoro ethoxy yemukati kazhinji inowedzera solubility.
Kukurudzira kana kubvongodza: Mechanical kubvongodza kana kubvongodza kunofambisa kupinda kwezvinonyungudutsa mukati mepolymer matrix uye inomhanyisa nzira yekunyungudika.
Inonyanya kushandiswa nzira dzekubvisa:
Nzira dzinoverengeka dzinogona kushandiswa kunyungudutsa ethylcellulose:
Solution Mixing: Izvi zvinosanganisira kusanganisa ethylcellulose nemushonga wakakodzera uye kubvongodza musanganiswa kusvikira wapera zvachose. Iyi nzira inowanzoshandiswa mumarabhoritari.
Spray coating: Mumaindasitiri ekushandisa, ethylcellulose mhinduro dzinowanzo gadzirirwa iyo yekupfapfaidza yekuputira maitiro. Iyo inonyungudutsa inoputika, ichisiya firimu yakaonda ye ethylcellulose pane substrate.
Hot melt extrusion: Iyi nzira inosanganisira kudziyisa musanganiswa we ethylcellulose uye zvimwe zvinhu kune yakanyungudutswa mamiriro uye wozoiburitsa kuburikidza nekufa. Mushure mekutonhora, iyo ethylcellulose inosimbisa.
Kunzwisisa hunhu hwekunyungudika uye nzira dzakakosha pakugadzirisa ethylcellulose kune chaiyo maapplication.
Iko kushandiswa kukuru kwe ethyl cellulose:
Pharmaceutical industry:
Tablet Coating: Ethylcellulose inoshandiswa zvakanyanya sechinhu chekuputira mahwendefa kuti ipe inodzorwa kusunungurwa uye kudzivirira inoshanda yemishonga yemishonga.
Microencapsulation: Iyo microencapsulation tekinoroji inoshandiswa mumasisitimu ekutumira zvinodhaka kuchengetedza zvinodhaka kubva kune zvakatipoteredza.
indasitiri yezvekudya:
Edible Coatings: Ethylcellulose inoshandiswa sechinhu chinodyiwa pamichero nemiriwo kuwedzera hupenyu hwavo hwesherufu uye kuchengetedza hutsva.
Paints uye Coatings:
Inks uye Coatings: Ethylcellulose chinhu chakajairika muinki uye machira, ichipa firimu-kugadzira zvimiro uye inosimudzira kugadzikana kwekugadzirisa.
Plastic industry:
Polymer Additive: Inoshandiswa sechinhu chinowedzera mumapurasitiki kuvandudza maitiro avo ekugadzirisa, kupa kushanduka uye kuoma.
Adhesive:
Kupisa Melt Adhesives: Ethylcellulose inoshandiswa mukugadzirwa kweanopisa anonyunguduka adhesives kubatsira kuvandudza avo anonamira uye akabatana zvimiro.
Indasitiri yemachira:
Textile Kukura: Mukugadzira machira, ethylcellulose inoshandiswa mukuyera kuti ipe inodzivirira yekuvhara kune fiber uye kuwedzera simba rayo.
electronic product:
Photovoltaic zvishandiso: Nekuda kweiyo firimu-inogadzira uye dielectric zvivakwa, ethylcellulose inogona kushandiswa kugadzira mafirimu matete emidziyo yemagetsi, kusanganisira maseru ezuva.
Zvigadzirwa zvekuchengeta wega:
Cosmetic magadzirirwo: Inoshandiswa seyakakora uye inodzikamisa muzvigadzirwa zvezvizoro zvakaita semafuta uye lotions.
3D kudhinda:
Binders mu 3D kudhinda: Ethylcellulose inogona kushandiswa sebhainda mu 3D kudhinda maitiro, zvichibatsira kuchengetedza kuvimbika kwechimiro chechinhu chakadhindwa.
Indasitiri yemapepa:
Pepa kupfekedza: Ethyl cellulose inoshandiswa sepepa rekupotera kuvandudza zvimiro zvayo zvepasi, kuwedzera kudhinda uye kupa kusamira kwemvura.
Ethylcellulose ine maapplication mumaindasitiri akasiyana siyana nekuda kweiyo yakasarudzika solubility hunhu uye multifunctional zvivakwa. Disolution nzira chinhu chakakosha pakuona kugona kwavo, zvichiita kuti zvigadziriswe zvakagadzirirwa kune zvakanangana nezvinodiwa. Sezvo sainzi yepolymer ichienderera mberi, ethylcellulose inogona kuita basa rinowedzera kukosha mumhando dzakasiyana dzekushandisa, zvichibatsira mukuvandudzwa kwezvigadzirwa zvepamberi uye zvigadzirwa.
