Ethylcellulose ipolymer inoshandiswa zvakasiyana-siyana uye inoshandiswa mumaindasitiri akasiyana-siyana, kusanganisira mishonga, machira, manamatisi uye chikafu. Mhando dzakasiyana dze ethylcellulose dzinogadziriswa kuti dzisangane nezvinodiwa zvakananga maererano nekusimba, huremu hwemamorekuru nezvimwe zvinhu.
Maumbirwo e ethyl cellulose:
Ethylcellulose inobva mu cellulose, polymer yechisikigo inowanikwa mumadziro emasero emiti. Kubviswa kwe ethyl cellulose kunosanganisira kuiswa kwemapoka e ethyl mukushanda kwe hydroxyl (-OH) kwe cellulose. Kugadziriswa uku kunoita kuti ethylcellulose ive nehunhu hwakasiyana, zvichiita kuti isununguke mu organic solvents uye kupa kugona kwakanaka kwekugadzira firimu.
Hunhu hwe ethylcellulose:
Kunyungudika: Ethylcellulose inonyungudika mumhando dzakasiyana dzezvinhu zvinonyungudika, zvakaita sealcohols, ketones, esters, nezvimwewo.
Hunhu hwekugadzira mafirimu: Hunhu hwakanaka hwekugadzira mafirimu, hwakakodzera kuputirwa nemafirimu.
Kupisa: Ethylcellulose inoratidza hunhu hwekupisa, zvichiita kuti iumbwe kana yapiswa.
Kusashanda: Hazvina makemikari, zvichipa kugadzikana mukushandiswa kwakasiyana-siyana.
Mhando dzeEthylcellulose:
1. Giredhi re viscosity yakaderera:
Magiredhi aya ane huremu hwakaderera hwemamorekuru uye nekudaro viscosity yakaderera.
Yakanakira kushandiswa kunoda machira matete kana mafirimu.
Mienzaniso inosanganisira mishonga inoburitswa nemutemo uye machira matete ari pamapiritsi.
2. Chikamu chepakati che viscosity:
Huremu hwepakati uye kusimba kwemuviri.
Inoshandiswa zvakanyanya muindasitiri yemishonga pakugadzira mishonga inoburitswa kwenguva refu, uko kuenzana pakati pekukora kwepurasitiki uye mwero wekuburitswa kwayo kwakakosha.
Inoshandiswawo mukugadzira manamatisi akakosha uye zvinonamira.
3. Giredhi repamusoro rekupenya:
Magiredhi aya ane huremu hwakawanda hwemamorekuru uye nekudaro kusimba kwakakwirira.
Yakanakira kushandiswa kunoda machira akakora kana mafirimu.
Inoshandiswa mukugadzira zvinhu zvinodzivirira zvakaita seinki, pendi nemavarnish.
4. Chikamu chakatsetseka:
Magiredhi aya ane saizi diki dzezvimedu, izvo zvinobatsira kuti machira anyatsopfava uye kuvandudza kupararira kwemvura mumhinduro.
Tsvaga maapplication ekugadzira inki dzekudhinda dzemhando yepamusoro uye macoatings ekugadzirira nzvimbo dzakanaka.
5. Magiredhi emhando yepamusoro e ethoxy:
Ethylcellulose ine mwero wepamusoro we ethoxylation.
Inopa kunyungudika kwakawedzerwa mumhando dzakasiyana-siyana dzezvinonyungudutsa.
Inoshandiswa mukushandiswa kunoda mapolymer anonyungudika zvakanyanya, senge mamwe maformula emishonga.
6. Chiyero chehunyoro hwakaderera:
Ethyl cellulose ine hunyoro hushoma.
Yakanakira kushandiswa uko kunetseka kwekunzwa hunyoro kuri dambudziko, senge kugadzirwa kwemishonga inobatwa nemvura.
7. Magiredhi eThermoplastic:
Magiredhi aya anoratidza hunhu hwakanyanya hwe thermoplastic.
Inoshandiswa mukugadzira zvinhu apo zvinhu zvinoda kunyoroveswa uye kuumbwa pakupisa kwakanyanya.
8. Kuburitswa kwedanho rinodzorwa:
Yakagadzirirwa mishonga inoda kuburitswa kwemishonga kwenguva yakareba.
Yakagadzirirwa kuwana kinetics yekusunungurwa inodiwa uku ichichengetedza kugadzikana.
Mashandisirwo e ethylcellulose:
1. Mishonga:
Mishonga inodzorwa inoburitswa.
Mapiritsi ekufukidza kuravira uye kunyungudika kwakadzora.
Chinosunga magranules mukugadzira mapiritsi.
2. Mapendi neingi:
Kuvhara kwekudzivirira panzvimbo dzakasiyana-siyana.
Inki dzekudhinda dzekudhinda ne flexographic ne gravure.
Kupfeka kwemotokari nemaindasitiri.
3. Zvinonamira nezvisimbiso:
Zvinonamira zvemhando yepamusoro zvekushandisa zvakasiyana-siyana.
Zvinovharira zvinoshandiswa pakubatanidza nekusimbisa mukuvaka nekugadzira.
4. Indasitiri yezvekudya:
Kupfeka michero nemiriwo zvinodyiwa kunoita kuti zvigare kwenguva refu.
Kuiswa kwezvinonhuwira nekuravira.
5. Mapurasitiki neKuumba:
Maitiro eThermoplastic mukushandiswa kwekugadzira.
Inogadzira zvigadzirwa zvepurasitiki zvemhando yepamusoro.
6. Zvigadzirwa zvemagetsi:
Inoshandiswa mukugadzira machira ekudzivirira ezvikamu zvemagetsi.
mhedziso:
Mhando dzakasiyana dze ethylcellulose dziripo kuti dzikwanise kushandiswa zvakasiyana-siyana mumaindasitiri akasiyana. Kubva kumishonga kusvika kumachira uye zvinonamatira, kugona kwe ethylcellulose kuri mumagiredhi ayo akasiyana, imwe neimwe yakagadzirirwa kusangana nezvinodiwa chaizvo. Sezvo tekinoroji nezvinodiwa muindasitiri zvichiramba zvichichinja, kugadzirwa kwemagiredhi matsva e ethylcellulose ane hunhu hwakawedzerwa kunogona kuita basa guru mukusangana nezvinodiwa zvemashandisirwo ari kubuda. Kunzwisisa mutsauko uripo pakati pemhando idzi kunoita kuti vagadziri vasarudze ethylcellulose yakakodzera kushandiswa kwayo, zvichiita kuti ive nechokwadi chekuti inoshanda zvakanaka uye inoshanda zvakanaka.
