HEC (HydroxyHyl Cellulose) uye HPMC (HPMC (HYDROKYPROPYL MetHylcellose) maviri anowanzo shandiswa cellulose derivatives, ayo anoshandiswa zvakanyanya mumaindasitiri mazhinji. Izvi zvigadzirwa zvave zvakakosha zvinoshanda zvinhu nekuda kwezvakange zvakasiyana zvemuviri uye zvemakemikari zvivakwa.
1. Hec (HydroxyTHYL Cellulose)
1.1 Basic chimiro uye zvivakwa
Hec is is is is is is-ionic yemvura-soluble polymer yakawanikwa nemakemikari kugadziridzwa kwemasikirwo emusikirwo cellulose. Yayo yekutanga chimiro ndiko kusuma kwehydroxytHyl vanodziya pane β-d-glucose skeleton yemheremalose. Nekuda kweiyo hydrophicity yeiyo hydroxylwl group muchimiro chayo, hec ine yakanaka solubility uye yakakora nzvimbo mumvura mumvura.
HEC inoratidzira kuderedza kwakanaka, kuumbwa kwefirimu uye lubricity, uye zvakare zvakare acid- uye alkali-inopesana uye ine yakanaka uye ine yakanaka biocomputer. Izvi zvivakwa zvinoita kuti ive inoshanda zvakanyanya, uye stabilizer uye yemufirimu-kugadzira mumiririri mune zvemvura. Uye zvakare, solution yehisiyo ine yakanaka thisxotropy, iyo inogona kuratidza yakakwira viscosity pasi peShear Simba, uye visikoka inodonha nekukurumidza pasi peShear Simba reShear. Hunhu uhwu hunoita kuti iwane kukosha kwakakosha kwekushandisa mukurapa kwakasiyana-siyana.
1.2 Kugadzirira Maitiro
Hec inonyanya kugadziriswa ne itstification maitiro ezvisikwa cellulose. Kazhinji inoshandiswa zvishandiso zvinoshandiswa zvinosanganisira maCellulose SOURCESS yakadai sekotoni uye huni, iyo inoitwa neEndlyone oxide mushure mekutora hydroxyll cellulose. Munguva yekuita kwese kuita, kutonga kwemamiriro ezvinhu (sekudzidzira, kwakadai tembiricha, ph kukosha uye nguva yakakosha pane iyo nhanho yekutsiva, solubility yechigadzirwa chekupedzisira.
1.3 Minda Yokushandisa
HEC inoshandiswa zvakanyanya mukuvakwa, marara, makemikari emazuva ese, mushonga uye chikafu. Muzvivakwa zvekuvaka, hec inoshandiswa zvakanyanya mumutumbi wetsiva uye gypsum seanoshanda zvakanaka uye stabilizer kuti uvandudze zvinopindirwa uye zvinopesana-zvino-sagging zvivakwa. Mujasi, hec inogona kushandiswa seanoshandiswa sedhioni uye rheology modifier yemvura-yakavakirwa mvura kuti uvandudze kuderedza uye kuseka kwematombo. Mumakemikari ezuva nezuva akadai seShompoo uye ruoko sanitizer, hec inoshandiswa seanoshandiswa sedhizaini uye moisturizer yekupa chigadzirwa chekunzwa uye kugadzikana. Uye zvakare, mune maindasitiri emishonga uye ecmace, hec inoshandiswa seyekuchinjika kwemapiritsi, iyo firimu aimbova yemakapuru, uye dhizaini uye stabilizer yekudya nekuda kwekunaka kwayo uye yakaderera yezvinhu zvakanaka.
2. HPMC (hydroxyprupyl methylcellose)
2.1 Basic chimiro uye zvivakwa
HPMC ndeye isiri-ionic cellulose ether yakawanikwa nekuunza hydroxypropropropropropropropropropropropyl uye mapoka mapoka muCellulose Skeleton. Zvakafanana neHep, HPMC ine yakanaka mvura solubility, kuremedza, firimu kugadzira zvivakwa uye biocomputer. Nekuda kweiyo nzira uye hydroxypruspropyl mapoka muchimiro chayo, HPMC isiri chete yakajairika salubility mumvura, asi zvakare inoratidza yakasimba nzvimbo yebasa uye kumiswa zvinhu.
Iyo viscosity yeHPMC mhinduro inokanganiswa zvakanyanya nekushisa. Mukati meimwe tembiricha tembiricha, iyo viscosity yeHPMC Solution inoderera nekuwedzera kupisa. Mukuwedzera, HPMC zvakare ine yakanaka gel zvivakwa. Kana tembiricha yekudzidzira inopfuura imwe kukosha, gel ichaumbwa. Ichi chivakwa chine kukosha kwakakosha kwekushandisa muminda yechikafu nemushonga.
2.2 Kugadzirira Maitiro
Kugadziriswa kweHPMC kwakafanana neHPM, uye kunoitwawo kuburikidza nekutsauka kwekuchinja kwemheremello. Usually, cellulose reacts with propylene oxide and methyl chloride under alkaline conditions to introduce hydroxypropyl and methoxy groups, respectively. Zvivakwa zveHPMC (senge viscosity, solubility uye solubility uye magetsi ekumisikidza) anogona kudzorwa nekugadzirisa huwandu hwekutsiva uye maitiro ekutsiva.
2.3 Masvinda Ekushandisa
HPMC ine huwandu hwakawanda hwekushandisa mumunda wekuvaka, mushonga, chikafu nemazuva ese emakemikari. Mukuvaka Mumunda wekurapa, HPMC inoshandiswa seyekudzoserwa, inonamatira uye capsule inovhara zvinyorwa zvemahwendefa, izvo zvinogona kudzora zvinobudirira mishonga uye kugadzirisa kugadzikana kwezvinodhaka. Muindasitiri yekudya, HPMC inoshandiswa zvakanyanya sedhizimusi uye emulsifier muzvinhu zvakabikwa, zvigadzirwa zvemukaka uye condiments kuti dzivandudze kugadzirwa uye kuravira kwezvigadzirwa. Mukuwedzera, HPMC zvakare inoshandiswa zvakanyanya mumakemikari ezuva nezuva senge shampoo, conditioner, yechiso yekuchenesa, etc.
Sezvo maviri akakosha cellulose derivatives, hec uye hpmc anotamba yakakosha basa mune akawanda maindasitiri. HEC inoshandiswa zvakanyanya mukuvaka, kuungana, kwemakemikari emazuva ese nemushonga nekuda kwekunaka kwakanakisa, firimu-fomu uye bigishomis. Hpmc, kune rumwe rutivi, anoita basa rakakosha mukuvaka, mushonga uye maindasitiri ezvekudya nekuda kwesimba rayo rakasarudzika uye minda yakasarudzika yekushandisa. Nekufambisira mberi kwehunyanzvi, maitiro ekugadzirira uye minda yekushandisa yeiyi zvinhu zviviri zvinoenderera mberi nekuwedzera, kuunza zvimwe mukana wekuvandudza maindasitiri ane hukama.
