Cellulose ether HE series, kureva, hydroxyethyl cellulose, ichena kune mukaka chena hupfu. Inogona kunyungudutswa mumvura inopisa uye mumvura inotonhora, asi hazvisi nyore kunyunguduka mune organic solvents. Jinshi brand cellulose ether HE dzakatevedzana zvigadzirwa zvine simba rekuchengetedza mvura, kugadzira firimu, kuramba munyu uye kukora mhedzisiro. Iyo zvakare ine yakanakisa kuenderana kwemavara uye ndeye yakanakira yekuwedzera mune latex application.
Hydroxyethyl cellulose HEC inowanzoshandiswa thickener mumachira uye ine zvinotevera zvakanakira:
(1) Yakasimba versatility Hydroxyethyl cellulose HEC isiri-ionic mvura-soluble polymer inogona kushandiswa muhupamhi pH renji (2-12). Inogona kusanganiswa nezvikamu mune zvakajairika coatings (senge pigment, additives, soluble salts uye electrolytes) pasina abnormal phenomena. the
(2) Kuvaka kwakanaka. Iyo yekuputira yakakora ne hydroxyethyl cellulose HEC ine pseudoplasticity, saka inogona kuiswa nekukwesha, kupfapfaidza, roller coating uye dzimwe nzira dzekuvaka. Zvakanakira, kuenzana zvakare zviri nani. the
(3) Hapana chakaipa chinokanganisa pafirimu yekuputira. Nekuda kwekusatarisika kwemvura pamusoro pekunetsekana kwemaitiro eHEC aqueous solution, hazvisi nyore kupupa panguva yekuvaka nekugadzira, uye kune kushomeka maitiro ekugadzira makomba emakomo uye mapini. the
(4) Kukura kwakanaka kwemavara. Hydroxyethyl cellulose HEC ine yakanakisa miscibility ine akawanda mabhainda uye colorants, kuitira kuti pendi yakagadzirwa ive yakanaka kugadzikana kwemavara uye kuenderana.
(5) Kugadzikana kwakanaka kwekuchengetedza. Munguva yekuchengetwa kwepende, inogona kuchengetedza kumiswa uye kupararira kwe pigment, pasina matambudziko ekuyangarara uye kutumbuka. Pane mvura shoma shoma pamusoro pepende. Kana tembiricha yekuchengetedza ichichinja, viscosity yayo inoramba yakafanana. zvakanyanya kugadzikana.
