Cellulose ethers anochinja-chinja uye anochinja-chinja mapolymers ane maapplication mumaindasitiri akasiyana siyana, anosanganisira kugadzirwa kwehuchi ceramics nezvimwe zvigadzirwa.
1. Nhanganyaya kune cellulose ether:
Cellulose ethers zvinobva kune cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro.Inowanikwa nekugadziriswa kwemakemikari ye cellulose, zvichiita kuti mvura-inonyunguduka kana mvura-inopararira mapolymers.Zvinowanzowanikwa zve cellulose zvinosanganisira huni pulp, donje, uye zvimwe zvezvirimwa.
2. Mhando dze cellulose ethers:
Kune akawanda marudzi e cellulose ethers, imwe neimwe iine akasiyana zvivakwa akakodzera kune chaiwo maapplication.Mamwe marudzi akajairika anosanganisira methylcellulose (MC), ethylcellulose (EC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), uye carboxymethylcellulose (CMC).Kusarudzwa kwe cellulose ether kunoenderana nezvinodiwa zvechigadzirwa chekupedzisira.
3. Maitiro ekugadzira:
Kugadzirwa kwema cellulose ethers kunosanganisira matanho akati wandei, anosanganisira kubvisa cellulose, kugadzirisa kemikari, uye kucheneswa.Cellulose inotanga kutorwa kubva muzvirimwa uyezve kemikari maitiro anoshandiswa kuunza mapoka anoshanda akadai semethyl, ethyl, hydroxyethyl kana carboxymethyl.Iyo inoguma cellulose ether inobva yacheneswa kubvisa tsvina uye kuwana hunhu hunodiwa.
4. Zvinhu zve cellulose ether:
Cellulose ethers vane zvinhu zvakasiyana-siyana zvinodikanwa, zvichiita kuti zvive zvakakodzera kune zvakasiyana-siyana zvekushandisa.Izvi zvinosanganisira kunyungudika kwemvura, kugona kugadzira firimu, kugona kukora, uye kugadzikana pamusoro petembiricha yakakura uye pH renji.Izvi zvivakwa zvinobatsira mukusiyana-siyana kwe cellulose ethers mumaindasitiri akasiyana.
5. Kushandiswa kwe cellulose ether:
Cellulose ethers inoshandiswa mumaindasitiri mazhinji, anosanganisira emishonga, chikafu, kuvaka, machira uye ceramics.Mashandisirwo ayo anotangira kubva pakushandiswa seanokora mumiriri mune zvekudya kusvika pakusimudzira zvimiro zvezvivakwa zvekuvaka.Mumunda we ceramics, cellulose ethers inoita basa rakakosha mukugadzirwa kwemizinga yehuchi.
6. Cellulose ether mumizinga yekeramic:
Zviumbwa zvehuchi zviumbwa zvine maseru akarongwa ane hexagonal kana patani yemuzinga.Aya maceramics anozivikanwa nepamusoro penzvimbo, yakaderera kupisa kwekuwedzera, uye yakanakisa kupisa uye hukuru hwekutamisa zvivakwa.Cellulose ethers inoshandiswa mukugadzira mizinga yehuchi nekuda kwezvikonzero zvinotevera:
Binders uye Rheology Modifiers: Cellulose ethers inoshanda semasungiro, ichibata zvidimbu zveceramic pamwe chete panguva yekuumba.Pamusoro pezvo, inoshanda senge rheology modifier, inokanganisa kuyerera uye deformation yeceramic slurries.
Green body formation: Ceramic slurries ine cellulose ethers inoshandiswa kuumba miviri yakasvibira yehuchi dzekeramics.Mitumbi yakasvibira haina kupiswa ceramic zvimiro zvakaumbwa uye kuomeswa isati yaenderera mberi nekugadzirisa.
Kubatanidza uye kuomeswa: Cellulose ethers inobatsira maceramic particles kubatanidzwa panguva yekuomesa.Iyo inodzivirira kutsemuka uye deformation, kuve nechokwadi kuti muviri wakasvibira unochengetedza hunhu hwayo.
Kusvirwa nekunyunguduka: Muzvinhanho zvinotevera zvekugadzirwa kwemuzinga weuchi, ma cellulose ethers anotsva, achisiya mavhodhi anobatsira kuumba chimiro chemuzinga.Iyo sintering process inozoenderera mberi nekuwana yekupedzisira ceramic chigadzirwa.
7. Zvimwe zvinoshandiswa zve cellulose ethers:
Kuwedzera kune huchi ceramics, cellulose ethers inoshandiswa mune akasiyana ezvimwe zvigadzirwa nemaindasitiri:
Pharmaceutical: Inoshandiswa sebhainda uye disintegrant mukugadzira piritsi.
Indasitiri yechikafu: Cellulose ethers inoshandiswa seyakakora, inosimbisa uye emulsifiers muchikafu.
Zvishandiso Zvekuvaka: Inosimudzira zvimiro zvedhaka, zvinonamira uye machira.
Machira: Cellulose ethers anoshandiswa mukudhinda machira uye saizi maapplication.
8. Zvinetso uye kufunga:
Nepo cellulose ethers ichipa zvakawanda zvakanaka, kushandisa kwavo kunopawo mamwe matambudziko.Izvi zvinogona kusanganisira zvingangoitika zvezvakatipoteredza zvine chekuita nemaitiro ekugadzira uye kudiwa kwekuwana zvigadzirwa zvakachengetedzeka.Basa rekutsvagisa nekusimudzira ririkuenderera mberi kugadzirisa matambudziko aya uye kuvandudza kusimba kwese kwesero ether zvigadzirwa.
9. Mafambiro nebudiriro:
Sezvo tekinoroji ichifambira mberi uye kusimba kunova nyaya inonyanya kukosha, ramangwana rema cellulose ethers rinogona kusanganisira hunyanzvi mumagadzirirwo ekugadzira, kuwedzera kushandiswa kwebio-based raw materials, uye kuvandudzwa kwezvishandiso zvitsva.Iko kuita kwakasiyana-siyana kwe cellulose ethers kunoita kuti ive chinhu chinovimbisa kune akasiyana maindasitiri, uye kutsvagisa kunoenderera mberi kunogona kuratidza mikana mitsva.
10. Mhedziso:
Cellulose ethers mapolymer anoshanda akawanda ane akawanda maapplication mumaindasitiri akati wandei.Kushandiswa kwayo mumaserura ceramics inosimbisa kukosha kwayo mukugadzira zvinhu zvepamberi zvine zvimiro zvakasiyana.Sezvo maindasitiri achiramba achitsvaga zvinhu zvinogara uye zvinoshanda, cellulose ethers inotarisirwa kuita basa rakakosha mukuzadzisa izvi zvinodiwa.Tsvagiridzo inoenderera mberi uye budiriro ichawedzera kuwedzera mashandisirwo ecellulose ether zvigadzirwa uye kuwedzera kusimba kwazvo.
