Cellulose ethers imhando yepolymer compound inowanikwa nekugadziriswa kwemakemikari echisikigo cellulose. Iwo anoshandiswa zvakanyanya muindasitiri uye kugadzira chikafu nemimwe minda. Vane zvakakosha zvakakosha semakobvu mukuumbwa. Kune marudzi akasiyana-siyana e-cellulose ethers, akadai se methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), carboxymethylcellulose (CMC), nezvimwewo. zvivakwa, zvine chaiwo mashandisiro ekushandisa.
1. Excellent thickening kuita
Cellulose ethers inogona kupa yakakosha kukora mhedzisiro pamazinga ekuwedzera akaderera. Izvi zvinodaro nekuti cellulose molecular cheni inowedzera kana yakanyungudika mumvura, ichiwedzera viscosity yemhinduro. Zvingave mumasisitimu ane aqueous kana organic solvents, cellulose ethers inogona kuvandudza kuenderana kwezvinwiwa nekugadzira mayunifomu colloidal mhinduro, ichivapa yakanaka rheology. Iyi thickening effect yakanyatsogadzikana uye inogona kunyatso kudzora fluidity uye kuwirirana kwegadziriro, zvichibvumira chigadzirwa kuchengetedza kushanda kwakafanana panguva yekuchengetedza kana kushandiswa.
2. Thermal kugadzikana uye moisturizing zvinhu
Cellulose ethers inoratidza kugadzikana kwakanaka pasi pemamiriro ekushisa akawanda, kunyanya mamwe marudzi akadai seHPMC, anogona kuchengetedza kunaka kwekukora pasi pemamiriro ekupisa. Kupisa kwavo kupisa kunoita kuti ive yakakodzera kushandiswa munzvimbo dzinoda kudziya kwepamusoro-soro senge kugadzira chikafu, zvekuvaka uye machira. Pamusoro pezvo, cellulose ethers zvakare ine yakanaka yekunyorovesa zvivakwa uye inogona kunonoka kubuda kwemvura mufomula. Izvi zvinonyanya kukosha kune mafomula anoda kwenguva refu hydration kana dziviriro kubva pakuoma, senge zvizorwa, mishonga yemishonga, kana zvekuvakisa.
3. Kugarisana uye Biocompatibility
Cellulose ether ine kugarisana kwakanaka neakasiyana siyana emakemikari zvinongedzo uye haina kujaira kune kemikari maitiro nemamwe maformula emhando. Izvi zvinozvipa kuwanda kwekushandisa mumhando dzakasiyana siyana. Semuenzaniso, mukuputira, zvinonamatira, emulsions uye suspensions, cellulose ethers inogona kugarisana nemhando dzakasiyana-siyana pasina kukuvadza kushanda kwese kwechigadzirwa. Mukuwedzera, sezvo cellulose ether inotorwa kubva kune yakasikwa cellulose, ine biocompatibility yakanaka uye inogona kuderedzwa nemuviri wemunhu kana nharaunda. Nokudaro, inoshandiswawo zvakanyanya muzvokudya, mishonga uye zvizoro, kunyanya kana zvinodiwa zvekuchengetedza zvakakwirira. Mune yakakwira fomula, isarudzo yakanakira gobvu.
4. Kumiswa uye kuparadzira mhedzisiro
Cellulose ethers inokwanisa kuchengetedza zvimedu zvakasimba zvakafanana zvakaturikwa mukuumbwa uye kudzivirira kuti zvisagadzikane. Inopa kugadzikana kwakanaka kwekumisa nekukora uye kugadzirisa rheology yemhinduro. Semuenzaniso, mupendi uye machira, kushandiswa kwe cellulose ethers kunogona kudzivirira delamination ye pigment kana zvimwe zvikamu zvemukati uye kuve nechokwadi chekufanana kwechigadzirwa. Mukugadzira zvinodhaka, zvinogona kubatsira kugovera zvinosanganisirwa zvinoshanda zvakaenzana, ive nechokwadi chekuenderana zvemukati mezvishandiso zvinoshandiswa mudosi yega yega, uye kuvandudza kugadzikana kwezvinodhaka uye kushanda.
5. Easy solubility uye nyore kugadzirisa
Cellulose ether inogona kunyungudutswa mumvura inotonhora kana inopisa kuti igadzire inoonekera kana translucent mhinduro, uye kukurumidza kwekunyungudika kunokurumidza. Izvi zvinoita kuti ishande nekukurumidza panguva yekugadzira uye kugadzirisa uye inovandudza kugadzirwa kwehunyanzvi. Uye zvakare, kugadzirisa kwe cellulose ether kuri nyore kwazvo uye kazhinji hakudi yakakosha michina uye maitiro. Inogona kutonhora kushandiswa kana kupisa kushandiswa kuti ienderane nemhando dzakasiyana-siyana dzekugadzirisa. Inogona kunyatso kudzora kuwirirana uye muromo wezvigadzirwa muindasitiri yechikafu, sekugadzirwa kweaizikirimu, zvigadzirwa zvemukaka uye zvakabikwa.
6. Wedzera kugadzikana kwechigadzirwa uye hupenyu hwesherufu
Cellulose ethers inogonawo kuita sezvigadziro mukugadzirisa, kunyanya mu emulsions, suspensions uye colloidal systems. Nekukora uye kugadzirisa rheological properties, cellulose ethers inogona kuvandudza kugadzikana kwemuviri weiyo system uye kudzivirira delamination, sedimentation uye agglomeration. Semuenzaniso, mu emulsion systems, cellulose ethers inogona kunyatsodzivirira kuparadzaniswa kwemafuta nemvura, kuvandudza kufanana uye kugadzikana kwe emulsion, nokudaro kuwedzera mararamiro ehupenyu hwechigadzirwa.
7. Ushamwari hwezvakatipoteredza
Iyo mbishi ye cellulose ether inongotorwa uye inogona kuderedzwa pachisikigo mushure mekushandiswa, saka ivo vakatanhamara maererano nekushamwaridzana kwezvakatipoteredza. Kuenzaniswa nemamwe petrochemical-derived thickeners, cellulose ethers ine zvishoma zvinokanganisa zvakatipoteredza uye inosangana nezvinodiwa zvekusimudzira. Kunyanya mukuvaka, kuvhara uye mamwe maindasitiri, kushandiswa kwe cellulose ethers semakobvu hakungogone kuvandudza mashandiro echigadzirwa, asi zvakare kuderedza kukanganisa kwakashata pane zvakatipoteredza.
8. Yakasiyana-siyana yekushandisa
Nekuda kwekusiyana-siyana kwema cellulose ethers, anogona kushandiswa mune chero kugadzirwa kunoda kukora. Kunyanya zvinosanganisira: indasitiri yezvokudya, zvizoro, mishonga, majasi, zvinhu zvekuvaka, kudhinda ingi, detergents, etc. Muzvokudya, inogona kushandiswa se-low-calorie thickening agent kuti ibudise zvigadzirwa zvakaderera-mafuta, zvichipa mafuta-sekuravira. Muzvizoro, cellulose ethers inobatsira kuvandudza kunzwa uye kupararira kwemafuta uye mafuta ekuzora, zvichipa lubrication inogara kwenguva refu. Mumunda wezvivakwa zvekuvaka, inoshandiswa mudhaka rakaoma, matanda anonamira, gypsum uye zvimwe zvigadzirwa kuti zvingonatsiridza kuwirirana, asi zvakare kusimudzira kuita kwekuvaka uye kutsemuka kuramba kwezvinhu.
9. Kudzorwa kusunungurwa uye kuendesa zvinodhaka
Cellulose ethers inogonawo kushandiswa kugadzira mishonga inodzorwa-inoburitswa, zvichibatsira kuti mishonga ibudiswe zvishoma nezvishoma mumuviri uye kuwedzera nguva yavo yekuita. Semuenzaniso, hydroxypropyl methylcellulose (HPMC) inowanzoshandiswa kugadzira mahwendefa anoramba achiburitswa kuti ave nechokwadi chekuburitswa kwezvinodhaka kwenguva yakareba, kuvandudza mhedzisiro yekurapa nekuderedza kuwanda kwemishonga. Ichi chivakwa chinoita cellulose ethers akakodzera ekuwedzera mumishonga yekugadzira mishonga.
Iwo akawanda mabhenefiti e cellulose ether seanokora, anosanganisira yakanakisa kukora mhedzisiro, kugadzikana kwekupisa, kuchengetedza mwando, kugona kumisa, kugadzirisa nyore uye kushamwaridzana kwezvakatipoteredza, zvinovaita sarudzo dzakakodzera mumagadzirirwo emazuva ano. Huwandu hwayo hwakasiyana hwekushandisa uye kuenderana kwakanaka kunoita kuti cellulose ether itore chinzvimbo chakakosha munzvimbo dzakasiyana siyana sekudya, zvizorwa, mushonga uye kugadzirwa kwemaindasitiri. Mune ramangwana rekugadzira dhizaini, zvakanakira cellulose ethers zvicharamba zvichisimudzira kushandiswa kwavo kwakakura mumaindasitiri akasiyana.
