Cellulose ether (CE) kirasi yerudzi rwakawanikwa nemakemikari kugadzirisa cellulose. Cellulose ndicho chinhu chikuru chechirwere chemasero madziro, uye cellulose eter tevedzeri wePolymers yakagadzirwa neye hydroxyl mapoka (-Ooh) mu cellulose. Ivo vanoshandiswa zvakanyanya muminda yakawanda senge zvekuvaka, mushonga, chikafu, zvizoro, etc., uye zvinoshandiswa zvakanyanya mumagiripi akasiyana siyana nekuda kwezvivakwa zvavo zvemuviri uye zvemakemikari uye zvinowedzera.
1. Kugadziriswa kwe cellulose ana
Cellulose etana inogona kukamurwa kuva dzakasiyana mhando zvichienderana nemhando dzevatambi vezvemakemikari. Iyo yakajairika chikamu chinoenderana nemusiyano muzvidzidzo. Company cellulose ana ana ana anotevera:
Methyl cellulose (mc)
Methyl Cellulose inogadzirwa nekutsiva iyo hydroxyl chikamu che cellulose molecule ine methyl (-ch₃). Iyo ine yakanaka yakakura, yemafirimu-ekuumba zvinhu uye zvinoshandiswa zvinowanzo shandiswa mune zvekuvakisa zvekuvakisa, hukudzo, mishonga uye maindasitiri ezvekudya.
Hydroxyprupyl methylcellose (HPMC)
HydroxyPropyl methylcellose icther cellulose ether, iyo inoshandiswa zvakanyanya muzvivakwa zvekuvaka, mushonga, mitambo yezuva nezuva nekuda kwekushushikana kwayo kwemvura uye nemakemikari. HPMC is nonitic cellulose ether nezvivakwa zvekuchengetwa kwemvura, kuremedza uye kugadzikana.
Carboxymethyl cellose (cmc)
Carboxymethyl Cellelose ndeye anonic cellulose ether inogadzirwa nekuunza carboxymethyl (-ch₂cooh) mapoka mu cellulose mamorekuru. CMC ine yakanakisa mvura solubility uye inowanzoshandiswa seye thickkener, stabilizer uye kumisa mumiririri. Inotaridza basa rakakosha pakudya, mushonga uye cosmetics.
Ethyl Cellulose (EC)
Ethyl Cellulose anowanikwa nekutsiva iyo hydroxyl boka mu cellyl (-ch₂ch₃). Iyo ine hydrophosity uye inowanzoshandiswa sefirimu yekubatanidza mumiriri uye inodzorwa kuburitswa zvinyorwa muindasitiri yemishonga.
2.. Zvepanyama uye zvemakemikari zvivakwa zve cellulose ana
Zvivakwa zvemuviri uye zvemakemikari zve cellulose ana vana zvakabatana nezvinhu zvakaita serudzi rwechinguvana ether, mhando yekutsiva uye iyo nhanho yekutsiva. Zvivakwa zvayo zvinobatanidza zvinotevera:
Solubility mvura uye solubility
Mazhinji mheremalose eter ane yakanaka mvura solubility uye inogona kunyungudutswa mumvura inotonhora kana inopisa kuti ugadzire mhinduro inojekesa coolution. Semuenzaniso, HPMC, etc.
Kuremadza uye mafirimu-ekuumba zvinhu
Cellulose ana vanayo zvakanakisa zvinhu zvinokonzeresa uye unogona kuwedzera zvinowedzera zvevisiko zvemvura. Semuenzaniso, kuwedzera HPMC yekuvaka zvinhu zvinogona kuvandudza plasiki uye kushanda kwemutema uye kusimudzira anti-sagging zvivakwa. Panguva imwecheteyo, cellaulose.com.rolose vainakidzwa firimu-kugadzira mafirimu uye vanogona kuumba yunifomu yekudzivirira firimu pamusoro pezvinhu, saka ivo vanoshandiswa zvakanyanya mumatombo uye zvipfeko zvinodhaka.
Kuchengeta kwemvura uye kugadzikana
Cellulose ana ana ana anayo kuve nemvura yakanaka yekuchengetedza, kunyanya mumunda wezvinhu zvekuvaka. Cellulose anaiters kazhinji inowanzoshandiswa kuchengetwa kwemvura yekuchengetwa kwemvura yeiyo coment door, kuderedza kuitika kwerukova shrinkage marara, uye kuwedzera hupenyu hwebasa remutya. Mundima yekudya, CMC inoshandiswawo sekambani yekunonoka kuchema chikafu.
Chemical Kugadzikana
Cellulose ana ana vana vakaratira makemikari akanaka muAcid, ALKALI uye ELKALE Solutions, uye inogona kuchengetedza chimiro chavo uye kushanda mune dzakasiyana siyana emakemikari emakemikari. Izvi zvinovatendera kuti vashandiswe mune dzakasiyana siyana maindasitiri pasina kukanganiswa kubva kune mamwe makemikari.
3. Kugadzira maitiro e cellulose ether
Iko kugadzirwa kwe cellulose ether kunonyanya kugadziriswa ne itstification maitiro ezvisikwa cellulose. Maitiro ekutanga matanho anosanganisira kurapwa kweayo cellulose, erthitation maitiro, kucheneswa, nezvimwe.
Alkalization kurapwa
Chekutanga, zvakasikwa cellulose (senge machira, huni, etc.) inogadziriswa kushandura iyo hydroxyl chikamu mu cellulose mudhara inoshingairira.
Erafied maitiro
Iyo cellulose mushure mekunge alkalization inosangana neyekutsvaira mumiririri (akadai methyl chloride, profylene oxide, etc.) kugadzira cellulose ether. Zvichienderana nemamiriro ekuita, mhando dzakasiyana dze cellulose etana dzinogona kuwanikwa.
Kucheneswa uye kuoma
Iyo cellulose ether inogadzirwa nekuita kunocheneswa, kushambidzwa uye kwakaomeswa kuti uwane hupfu kana chigadzirwa chakadonha. Kuchena uye zvivakwa zvemuviri zvechigadzirwa chekupedzisira chinogona kudzorwa nekutevera tekinoroji yekugadzirisa.
4. Masisitiri ekushandisa e cellulose ether
Nekuda kweiyo yakasarudzika yemuviri uye yemakemikari zvivakwa zve cellulose ana anayo, inoshandiswa zvakanyanya muindasitiri mizhinji. Minda huru yekushandisa iri seinotevera:
Zvekuvaka
Mumunda wezvivakwa zvekuvaka, cellulose ana anainhu inonyanya kushandiswa sehana uye mvura inochengetedza vamiririri vekamenti yemutumbi uye gypsum zvigadzirwa. Cellulose eter yakadai seHPMC uye MC inogona kuvandudza basa rekuvaka, kuderedza kurasikirwa kwemvura, uye nekudaro kunowedzera kuderera uye kupenga kuramba.
Mushonga
Muindasitiri yemishonga, cellaulose ana anaimbo vanoshandiswa zvakanyanya seanorongedza vamiririri vezvinodhaka, zvinonamatira mahwendefa, uye zvinhu zvinodzorwa-zvakadzora. Semuenzaniso, HPMC inowanzoshandiswa kugadzirira zvinodhaka mafirimu uye ine yakanaka inodzorwa-kubudiswa.
Chikafu
CMC inowanzoshandiswa seanotenderedza, emulsifieri, uye stabilizer mune indasitiri yechikafu. Iyo inoshandiswa zvakanyanya mune zvinwiwa, zvigadzirwa zvemukaka, uye zvinhu zvakabikwa, uye zvinogona kuvandudza kuravira uye zvinonyungudza zvivakwa zvekudya.
Cosmetics uye zuva nezuva makemikari
Cellulose ana ana vana vanoshandiswa sehuku uye emelsififiers uye stabilizers mune cosmetics uye ezuva nezuva makemikari, izvo zvinogona kupa kusarudzika kwakanaka uye chimiro. Semuenzaniso, HPMC inowanzo shandiswa mune zvigadzirwa zvakaita se mazino uye shampoo kuvapa viscous kunzwa uye yakagadzikana kumiswa kwemhedzisiro.
Coatings
MuCoatings Indasitiri, Cellulose eths inoshandiswa senhema, mafirimu mafirimu, uye kumisa mumiriri, izvo zvinogona kuwedzera kuita kwekuvaka kwejasi, kuvandudza kuwanda, uye kupa zvakanaka pendi yemhando yefirimu.
5. Runyorwa rwekudzikisira rwemangwana re cellulose etana
Nekuwedzera kwekuda kwekudzivirira kwezvakatipoteredza, cellulose ether, sekubva kune chinobva kune zvakasikwa zvinowanikwa zviwanikwa, zvine tarisiro yakakura yekuvandudza. Yayo biodegradability, kuvandudza uye kuwedzera kuita kuti zvive zvinotarisirwa kuve zvakanyanya kushandiswa muminda yezvinhu zvakasvibirira, zvinhu zvinosemesa uye zvakangwara mune ramangwana. Uye zvakare, cellulose ether zvakare ine zvakare kutsvagisa uye kusimudzira mukana mune yakakwirira kukosha-yakawedzerwa minda yakadai seBiomedical engineering uye yakakwira zvinhu.
Sechigadzirwa chakakosha chemakemikari, cellulose ether ine huwandu hwakawanda hwekushandisa. Nekuchengetwa kwayo kwakanakisa, kudzokorora kwemvura, kuumbwa kwemvura uye kwakanaka kemikari kugadzikana, zvinoita basa risingaperi mumunda mizhinji dzakadai sekuvaka, mushonga, uye chikafu. Mune ramangwana, nekufambira mberi kwehunyanzvi hwekusimudzira uye kusimudzirwa kwenzvimbo dzekudzivirira dzemakompitirwo emasangano.
