EHEC uye MEHEC

EHEC (ethyl hydroxyethyl cellulose) uye MEHEC (methyl ethyl hydroxyethyl cellulose) mhando mbiri dzakakosha dze cellulose ethers dzinowanzoshandiswa mumaindasitiri akasiyana-siyana, kusanganisira pendi uye coating indasitiri.Ngationgororei zvakadzama mune imwe neimwe:

1. EHEC (Ethyl Hydroxyethyl Cellulose):
   • Chemical Structure: EHEC inotorwa kubva ku cellulose nekuunza ese ethyl uye hydroxyethyl mapoka pane cellulose musana.
   • Properties uye Mabasa:
     • EHEC inonyungudika mumvura uye inoumba pachena, viscous mhinduro.
     • Inoshanda seyakakora uye rheology modifier mumvura-yakavakirwa pendi uye machira, inodzora viscosity uye inovandudza mashandisirwo ekushandisa.
     • EHEC inopa pseudoplastic kana shear-kuonda maitiro ekupendera maumbirwo, zvichireva kuti viscosity inodzikira nekuwedzera kweshear rate, kuita kuti kuve nyore kushandisa uye kutsetseka kwebrashi.
   • Applications:
     • EHEC inoshandiswa zvakanyanya mukati nekunze pendi, maprimers, uye machira kuti uwane inodiwa kuenderana, kuyerera, uye kuyera zvivakwa.
     • Iyo inonyanya kushanda mukugadzira uko yakakwira viscosity pane yakaderera shear mitengo inodiwa kuti sag kuramba uye yakagadziridzwa firimu kuvaka.
2. MEHEC (Methyl Ethyl Hydroxyethyl Cellulose):
   • Mushonga Wemakemikari: MEHEC is modified cellulose ether ine methyl, ethyl, uye hydroxyethyl substituents pamusana we cellulose.
   • Properties uye Mabasa:
     • MEHEC inoratidza solubility yakafanana uye rheological properties kuEHEC asi paine mimwe misiyano mukuita.
     • Inopa masimba ekuchengetedza mvura yakagadziridzwa kana ichienzaniswa neEHEC, ichiita kuti ive yakanyatsokodzera maumbirwo apo yakawedzerwa nguva yakazaruka kana kuvandudzwa kwemavara kudiwa.
     • MEHEC inopa yakawedzera kukora kushanda uye kugadzikana pamusoro pehupamhi hwepH uye tembiricha mamiriro.
   • Applications:
     • MEHEC inowana kushandiswa mumvura-yakavakirwa pendi, machira, uye zvinhu zvekuvaka uko kwakagadziridzwa kuchengetedza kwemvura, kukora, uye rheological control inodiwa.
     • Inowanzo shandiswa mukugadzira pendi yekushongedza, machira akashongedzwa, uye hunyanzvi hwekupedzisa uko yakawedzera nguva yekushanda uye nekunatsiridza kuyerera zvivakwa zvakakosha.

Ese ari maviri EHEC neMEHEC akasiyana-siyana cellulose ether anopa maformulator kuchinjika mukuwana inodiwa maitiro ekuita mupendi-yakavakirwa mvura uye mapendi.Kupindirana kwavo nezvimwe zvinowedzera, nyore kubatanidzwa mukugadzirisa, uye kukwanisa kusimudzira zvinhu zvakakosha zvakadai sekutonga viscosity, kuchengetwa kwemvura, uye zvigadziro zvekushandisa zvinovaita zvikamu zvakakosha mukugadzirwa kwemhando yepamusoro yekushongedza.
