I. Sumo
HydroxytHyl Cellulose (HEC) isisiri-Ionic Four-Soluble Polymer Inoshandiswa zvakanyanya mumafuta ekubvisa, huku, kuvaka, makemikari ezuva nezuva, mapepa nemapepu nemimwe minda. HEC inowanikwa nemakemikari kugadziridzwa kwemheremalose, uye zvivakwa zvacho uye zvinoshandiswa zvinonyanya kutsanangurwa neiyo hydroxythinyl subsituels pane maneja emheremalose.
Ii. Maitiro ekugadzira
Maitiro ekugadzira ehec anonyanya kusanganisira matanho anotevera: Cellulose erafotifoti, kushambidza, kushomeka, kuomesa uye kuomesa. Izvi zvinotevera sumo yakazara padanho rega rega:
Cellulose erafied
Cellulose inotanga kurapwa nealkali kuumba alkali cellulose (cellulose alkali). Maitiro aya anowanzoitwa mune imwe nhetembo, achishandisa sodium hydroxide solution yekurapa zvakasikwa cellulose kuumba alkali cellulose. Maitiro emakemikari ari seinotevera:
Cell-OH +OH → Cell-O-na + H2OCELL-OH +OH → Cell-O-NA-NA-NA-NA-NA-NA-NA-NA
Zvadaro, Alkali Cellulose Inosangana neEtraylene oxide kuti aumbe hydroxytHyl cellulose. Kuita kwacho kunoitwa pasi pekumanikidzwa kwepamusoro, kazhinji 30-100 ° C, uye maitiro chaiwo anotevera:
Cell-o-na ch2o
Kuita uku kunoda kudzora chaiko kwekudziya kwekushisa, kumanikidzwa uye huwandu hwe ethylene oxide yakawedzerwa kuti ive nechokwadi uye mhando yechigadzirwa.
Kugeza
Iyo yakakonzerwa nehuku yakakwenenzverwa kazhinji ine isina kujairika alkali, ethylene oxide uye zvimwe zvigadzirwa, izvo zvinoda kubviswa nekugeza kwemvura yakawanda kana organic solvent kugeza. Mari yakakura yemvura inodikanwa panguva yekugeza kwemvura yekugezesa, uye iyo yakasviba mushure mekugeza inoda kurapwa uye kuiswa.
Kushomeka
Iyo yakanyorova hec mushure mekushambidza inoda kuve yakadzvanywa, kazhinji neVaCuum Filtration kana centrifugal kupatsanurana kuti uderedze zvinyoro-nyoro.
Kuomesa
Iyo yakasviba yechihedheni yakaomeswa, kazhinji nekupedza kuoma kana kupenya kuoma. Tembiricha uye nguva inofanira kudzorwa zvakanyatso kudzorwa panguva yekuomesa maitiro kudzivirira kupisa kwakanyanya kwesimba kana kuunganidzwa.
Kugeda
Iyo Hec HEC BLOCK inoda kuverengera pasi uye yakachengetedzwa kuti iwane yunifomu yehurongwa hwekugovaniswa, uye pakupedzisira gadzira hupfu kana chigadzirwa chekudonha.
III. Maitiro ekuita
Solubility yemvura
Hec ine yakanaka mvura solubility uye inogona kunyungudutsira nekukurumidza mumvura inotonhora uye inopisa kuti iite iyo inojekesa kana translucent mhinduro. Iyi solubility midziyo inoita kuti iwanzoshandiswa zvakanyanya seanotenderedza uye stabilizer mune huku uye zuva nezuva zvigadzirwa zvemakemikari.
Kuremedza
Hec inoratidza yakasimba inosimbisa mhinduro mumhedzisiro, uye viscosity yayo inowedzera nekuwedzera kwehuremu hwemanyorerwe. Iyi pfuma inokonzeresa inoita kuti itambe chikamu mukurapa, kudzokorora kwemvura uye kugadzirisa mashandiro ekuvaka mumvura-yakavakirwa mvura uye motsi yekuvaka.
Rheology
Hec mhinduro yemvura ine zvimiro zvakasarudzika, uye zvavasangano zvaro zvinoshanduka nekuchinja kwehasha, kuratidza shear kutetepa kana pseudoplastical. Iyi midziyo ye rateological inogonesa kugadzirisa fluidity nekuita kwekuvaka mumakororo uye mafuta emafuta ekudhirowa.
Emulsification uye kumiswa
Hec ine yakanaka emulsization uye kumiswa zvivakwa, izvo zvinogona kudzikisira zvimisikidzo zvimiswe kana madonhwe muhurongwa hwekuparadzira kudzivirira kuoma uye sedimentation. Naizvozvo, hec inowanzoshandiswa mune zvigadzirwa zvakadai sechipfuva nemishonga yezvinodhaka.
Biodegradability
HEC ndeyechisikigo cellulose inobviswa neakanaka biodergradability, hapana kusvibiswa kune zvakatipoteredza, uye zvinosangana nezvinodiwa zvekudzivirira zvakasvibirira zvezvakatodza.
Iv. Minda yekushandisa
Coatings
Mune zvemvura-zvakavakirwa mvura, hec inoshandiswa seanoshandiswa sediki uye stabilizer yekuvandudza iyo fluidity, kuita kwekuvaka uye maitiro ekurwisa ezvipfuyo.
Kuvaka
Muzvivakwa zvekuvaka, hec inoshandiswa mune yemukati-based-based forar uye putty poda kugadzirisa maitiro ekuvaka nekuchengetwa kwemvura.
Mazuva ese makemikari
MuDonthents, Shampoos, uye mazino, hec anoshandiswa seanoshandiswa sedhioni uye stabilizer kuvandudza kunzwa kwekunzwa uye kugadzikana kwechigadzirwa.
MafutaFields
Mukuchera mafuta anokwevera uye kupwanya mvura, hec inoshandiswa kugadzirisa iyo rheology uye kumiswa zvivakwa zvekukwevera kwemvura uye kuvandudza kuderedza kushanda uye kuchengeteka.
Mapepa
Muchiitiko chepapaniti, hec inoshandiswa kudzora pulp fluidity uye kuvandudza kufanana uye pamusoro pepepa.
Hydroxethyl Cellulose (HEC) yakave ichishandiswa zvakanyanya muminda yakawanda yemuindasitiri nekuda kwekunetseka kwayo kwemvura, kuremerwa, zvimisikidzwa uye kumiswa kwezvinhu zvakanaka. Maitiro ayo ekugadzira akakura. Kuburikidza nematanho e cellulose etera Mune ramangwana, nekuvandudzwa kwezvinodiwa zvekudzivirira zvakatipoteredza uye kufambira mberi kwehunyanzvi, tarisiro yekushandisa yehec ichave yakawedzera.
