1.Chemcial Specification

2.Zvigadzirwa Magiredhi

3.Hydroxyethyl Cellulose (HEC) Zvikumbiro:

Mumvura yakavakirwa pendi, inoita basa rekuparadzira nekudzivirira gels, kusimudzira kuita kugadzikana kweagglomerate system, kuve nechokwadi chekugovera homogeneous kwe pigment uye kupfekedza, uye kupa mhedzisiro yekukora, kuvandudza fluidity.

Mukuchera oiri, inoshandiswa seyakagadzika uye yekukora mumiriri, yekuzora mumiriri wekuchera matsime, kupedzisa uye kusanganisa kupa slurry yakanaka fluidity uye kugadzikana.

Mukuvaka, HEC inogona kushandiswa seyakakora mumiriri uye yakabatana mumiriri kuvandudza fluidity uye kushanda, kuwedzera kwekutanga gelling simba uye kudzivirira kupaza.

Mukukwesha nekubatanidza plaster, zviri pachena zvinogona kusimudza kubata mvura uye kusimba kwekubatana.

Mumazuva ese-kushandisa kemikari senge mushonga wemazino inopa yakanaka yemuviri uye kemikari pfuma, ichiita kuti ive yakanaka muchimiro, nguva yakareba yekuchengetedza, yakaoma kuoma uye kupinda mukati.

Mumunda wecosmetic, inogona kuwedzera kusimba kwezvinhu, kuwedzera lubrication uye kutsvedzerera.

Kunze kwezvo, ine yakafara application muinki, machira ekudhaya & kudhinda, kugadzira mapepa, mishonga yemishonga, chikafu, kurima nezvimwe.

4.Hydroxyethyl Cellulose (HEC) Kushandisa nzira :

Nzira Yokutanga: Yakananga Kuisa mukati

1. Dururira mvura yakachena mubhaketi rakapihwa nestirrer.

2. Pakutanga kurunga zvishoma nezvishoma, paradzira zvakaenzana HEC mumhinduro.

3. Gadzirisa kusvika maHEC granules atota zvakazara.

4. Tanga waisa anti-mildew agent, wobva wawedzera mukuwedzera senge pigment, disperser etc.

5. Ramba uchikurudzira kusvikira yose HEC uye additives yakanyungudika zvachose (viscosity mumushonga zviri pachena kuwedzera), wozoisa mune zvimwe zvigadzirwa kuti uite.

Yechipiri Nzira: Gadzirira Amai Doro Kuti Ushandise

Tanga wagadzirira doro raamai gobvu, wobva wariisa muchigadzirwa.Kunakira kwenzira yacho kuchinjika, doro rinogona kuiswa muchigadzirwa.Maitiro uye nzira yekushandisa yakafanana ne1-4 munzira(Ⅰ),be nyatso kurunga kusvika yanyungudika yanyungudika kuita zvinonamira uye mukobvu wobva waisa anti-mildew mudoro raamai nekukurumidza.

Yechitatu Nzira: Gadzirira Gruel-yakafanana Material Yekushandisa

Sezvo organic solvents isiri-solvents yeHEC, inogona kushandiswa kugadzira gruel-like material.Inonyanya kushandiswa ndeye ethylene glycol, propylene glycol uye film-forming agent (hexamethylene-glycol, diethyl glycol butyl acetate etc.) mvura, zvakare inogona kugadzirwa pamwe chete neorganic solvents kuita gruel-like material.

Gruel-senge zvinhu zvinogona kuiswa muchigadzirwa nekuti HEC mune gruel-yakafanana zvinhu yakanyoroveswa uye yakazvimba kumusoro, isa muchigadzirwa iyo inonyungudika nekukasira uye inokurudzira kukora, asi ramba uchimutsa kusvika yanyungudika zvachose.

Kazhinji gruel-like material inowanikwa nekusanganisa organic solvent kana mvura yechando neHEC muchikamu che6: 1, mushure me5-30 maminetsi HEC hydrolyzes uye kunyanya kuzvimba. Nzira yacho haigamuchirwi muzhizha nekuda kwekupisa kwekunze.

5.Application Guide yePaint Industries

High thickening Migumisiro

Hydroxyethy Cellulose inopa latex pendi kunyanya yakakwira PVA pendi ine yakanakisa coating performance.Kana iyo pendi yakakora paste, hapana flocculation ichaitika.

Hydroxyethy Cellulose ine yakakwira kukora mhedzisiro, saka inogona kuderedza dosi, kuvandudza mutengo-kushanda kwekugadzira, uye kuwedzera kugeza kuramba kwependi.

Yakanakisa Rheological Properties

Iyo aqueous solution yeHydroxyethy Cellulose isiri Newtonian system, uye zvimiro zvemushonga zvinonzi thixotropy.

Munzvimbo yakamira, mushure mekunge chigadzirwa chanyungudika zvachose, iyo yekubikira system inogona kuchengetedza yakanakisa kukora mamiriro uye inogona-kuvhura mamiriro.

Munzvimbo yekurasa, sisitimu inogona kuchengetedza ine mwero viscosity, ichiita zvigadzirwa zvine yakanakisa fluidity, uye kwete spatter.

Munguva yekutsvaira uye roller coating, chigadzirwa chiri nyore kupararira pane substrate, saka yakanakira kuvaka, uye panguva iyi, ine yakanaka spatter kuramba.

Pakupedzisira, mushure mekupfekedzwa kwepende kwapera, viscosity yehurongwa inokurumidza kudzoreredzwa, uye pendi yacho inokurumidza kuburitsa sagging pfuma.

Kupararira uye Solubility

Hydroxyethy Cellulose yose inobatwa nekunonoka kupera, uye munyaya yekuwedzera poda yakaoma, inogona kunyatsodzivirira caking uye kuve nechokwadi kuti hydration inotanga mushure mekupararira kwakakwana kweHEC powder.

Hydroxyethy Cellulose mushure mekurapa kwakakodzera kwepamusoro inogona kunyatso kudzora chiyero chekunyungudika uye viscosity yekuwedzera chiyero chechigadzirwa.

Kuchengetedza Kugadzikana

Hydroxyethy Cellulose ine yakanaka inodzivirira mildew kuita, inopa yakakwana nguva yekuchengetera pendi, uye zvinobudirira kudzivirira kugadzika kwe pigment uye fillers.a
