Ethylcellulose (EC) i polymer inoshanda zvakasiyana-siyana inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro. Ethyl cellulose inowanikwa nekugadzirisa cellulose nekuunza ethyl mapoka. Uku kugadziridzwa kunopa iyo polymer yakasarudzika zvivakwa zvinoita kuti ive yakakosha kune akasiyana maindasitiri ekushandisa.
Zviratidzo zve ethylcellulose:
1.Chemical chimiro:
Ethylcellulose inogadzirwa ne cellulose inowanikwa nekurapa cellulose ne ethyl chloride pamberi pe alkali. Mapoka ethyl anotsiva mamwe emapoka ehydroxyl mune cellulose chimiro. Chimiro chemakemikari ethylcellulose chinoratidzwa nekuvapo kwemapoka ethyl akabatanidzwa kune anhydroglucose units ye cellulose.
2. Solubility:
Ethyl cellulose haina kunyungudika mumvura, inova chinhu chakakosha chinoisiyanisa kubva kune yakasikwa cellulose. Nekudaro, inoratidza kunyungudika mune akasiyana organic solvents, kusanganisira madoro, ketoni, uye chlorinated hydrocarbons. Kunyungudika uku kunoita kuti ethylcellulose ikwane kune akasiyana-siyana ekuputira uye firimu-kugadzira maapplication.
3. Kugadzikana kwekupisa:
Ethyl cellulose ine kugadzikana kwakanaka kwekupisa uye inoshingirira kune tembiricha yepamusoro. Ichi chivakwa chakakosha pakushandisa uko zvinhu zvinodziya, sekugadzirwa kwemafirimu uye machira.
4. Kugona kugadzira firimu:
Chimwe chezvinhu zvinozivikanwa zve ethylcellulose kugona kwayo kwekugadzira firimu. Ichi chivakwa chinoshandiswa mumaindasitiri emishonga uye ezvekudya, uko ethylcellulose inoshandiswa kugadzira mafirimu ekuunza zvinodhaka uye machira anodyiwa, zvichiteerana.
5. Kuchinja uye plastiki:
Mafirimu ethylcellulose anozivikanwa nekushanduka uye kuumbwa kwawo, achiita kuti ave akakodzera kune maapplication ayo anoda inoshanduka asi yakagadzikana zvinhu. Ichi chivakwa chinonyanya kubatsira mumaindasitiri emishonga uye ekurongedza.
6. Kemikari inert:
Ethylcellulose ikemikari inert uye nekudaro inopesana nemakemikari mazhinji. Ichi chivakwa chinosimudzira kugadzikana kwayo munzvimbo dzakasiyana siyana uye inowedzera mashandisirwo ayo mumaindasitiri ane kazhinji kuratidzwa kumakemikari.
7. Low density:
Ethylcellulose ine density yakaderera, iyo inobatsira pakureruka kwayo. Ichi chivakwa chinobatsira mukushandisa uko huremu chinhu chakakosha, senge mukugadzirwa kwemafirimu akareruka uye machira.
8. Kuenderana nemamwe mapolima:
Ethylcellulose inoenderana neakasiyana mapolymers, achibvumira misanganiswa kuti igadzirwe neyakagadzirirwa zvivakwa. Uku kuwirirana kunowedzera mashandisirwo ayo nekugonesa kugadzirwa kwezvinhu zvakasanganiswa zvine zvivakwa zvakawedzerwa.
9. Hainakidzi uye haina hwema:
Ethylcellulose haina kunaka uye haina kunhuhwirira uye inokodzera kushandiswa mumaindasitiri emishonga uye ezvekudya uko hunhu hwekunzwa hwakakosha.
Kushandiswa kwe ethylcellulose:
1. Indasitiri yemishonga:
Tablet Coating: Ethylcellulose inowanzoshandiswa sechinhu chekuputira mahwendefa. Firimu yekuputira inopa inodzorwa kusunungurwa, kuchengetedzwa kubva kune zvakatipoteredza zvinhu, uye yakagadziridzwa kutevedzera kwemurwere.
Inodzorwa kuburitsa matrix: Ethylcellulose inoshandiswa mukugadzirwa kwezvinodhaka zvinodzorwa kuburitsa matrix mapiritsi. Kudzorwa kuburitswa maprofiles akawanikwa nekugadzirisa ukobvu hweiyo ethylcellulose coating.
2. Indasitiri yezvekudya:
Edible Coatings: Ethylcellulose inoshandiswa sechinhu chinodyiwa pamichero nemiriwo kuwedzera hupenyu hwavo hwesherufu uye kuchengetedza hutsva. Iyo ethylcellulose isinganakidze uye isinganhuwi inova nechokwadi chekuti haikanganise hunhu hwezvikafu zvakavharwa.
3. Packaging industry:
Flexible kurongedza mafirimu: Ethyl cellulose inoshandiswa mukugadzira anochinjika ekurongedza mafirimu. Flexibility, low density uye makemikari inertness inoita kuti ive yakakodzera kune zvikumbiro zvinoda kureruka uye kugadzikana kwemakemikari zvinhu.
4. Ingi uye coatings:
Kudhinda ingi: Ethylcellulose chinhu chakakosha pakudhinda inki maumbirwo. Kunyungudika kwayo uye firimu-kuumba zvinhu mumhando dzakasiyana-siyana dzemakemikari zvinogadzirisa zvinoita kuti zvive zvakanaka kune ingi dzinoshandiswa mu flexographic uye gravure kudhinda.
Wood Coatings: Ethylcellulose inoshandiswa muhuni yehuni kuti iwedzere kunamatira, kushanduka uye kuramba kune zvakatipoteredza zvinhu. Inobatsira kugadzira chifukidzo chakasimba uye chakanaka pahuni.
5. Adhesive:
Kupisa Melt Adhesives: Ethylcellulose inosanganisirwa mune inopisa inonyunguduka inonamira kuti ivandudze kuchinjika uye kubatanidza zvivakwa. Yakaderera mamorekuru uremu mamakisi ethylcellulose anonyanya kukodzera kugadzira anopisa anonyungudutsa anonamatira.
6. Zvigadzirwa zvekuchengeta wega:
Bvudzi Kuchengeta Zvigadzirwa: Ethylcellulose inowanikwa mune zvigadzirwa zvekuchengeta bvudzi senge styling gels uye hairspray. Iyo firimu-inogadzira uye inodzivirira mvura zvivakwa zvinobatsira iyo chigadzirwa fomula inopa inogara kwenguva refu kubata uye kubata.
7. Indasitiri yemachira:
Textile Sizing Agent: Ethyl cellulose inoshandiswa senge saizi muindasitiri yemachira kunatsiridza kusimba uye kugadzikana kwemachira uye machira panguva yekugadziriswa.
8. Indasitiri yemagetsi:
Electrode Material Binders: Muindasitiri yemagetsi, ethylcellulose inoshandiswa sebhainda remagetsi emagetsi panguva yekugadzira bhatiri. Inobatsira kuumba yakagadzikana electrode chimiro.
9. Indasitiri yeOiri neGasi:
Drilling Fluid Additives: Ethylcellulose inoshandiswa sechinhu chinowedzera mukuchera zvinwiwa muindasitiri yeoiri negasi. Inovandudza rheological properties yemvura uye inobatsira kudzora chiyero chekupinda panguva yekuchera mabasa.
Ethylcellulose inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana anosanganisira emishonga, chikafu, kurongedza, machira uye zvemagetsi nekuda kwekusanganiswa kwayo kwezvivakwa. Iko kushandiswa kwakasiyana-siyana kwe ethylcellulose, pamwe nekugona kugadzirisa zvimiro zvayo nekusanganisa nemamwe mapolymers, inoita ethylcellulose chinhu chakakosha kune zvakasiyana siyana zvinodiwa mumaindasitiri. Sezvo tekinoroji uye tsvagiridzo ichienderera mberi, mashandisirwo ethylcellulose angangowedzera, achisimbisa kukosha kwayo mumaindasitiri emazuva ano.
