Ndeipi nzira yekugadzira yemethylcellose?

Ndeipi basa re methyl cellulose ether mune yakaoma poda dowder?
A: Methyl HydroxyTH CellEthese ether (Mhec) uye methyl hydroxpropropropropropropropropropropropyl Cellulose

Mumunda weDry Powder Dorare, methyl Celler's gadziriso yakagadziridzwa yehuremu, TILE SAME, SPY-Lighting Moturu, Wallpaper Glue uye Caulking Fully. Mune dzakasiyana-siyana dzakaoma poda meths, methyl cellelose ether inonyanya kuita basa rekuchengeta kwemvura uye kureruka.

Ndeipi nzira yekugadzira yemethylcellose?
Mhinduro: Chekutanga, iyo cellulose chigadzirwa chakapwanyika, ndokuzoshandiswa uye chakabikwa uye chakabikwa pasi pechiitiko cheCaustic soda. Wedzera Olefin oxide (senge ethylene oxide kana profylone oxide) uye methyl chloride yekuwedzera. Pakupedzisira, kushambidza kwemvura uye kucheneswa kunoitwa kuti uzokupedzisira kuwana jira chena. Iyi powder, kunyanya mhinduro kwayo, ine zvivakwa zvinonakidza zvemuviri. Iyo cellulose ether inoshandiswa mune yekuvaka indasitiri iri methyl hydroxyl cellyl cellyl Ichi chigadzirwa chinoita basa rakakosha kwazvo mumunda weiyo yakaoma poda muhari. Basa rakakosha.

Ndeipi kuchengetedza kwemvura yeMethyl Cellulose ether (MC)?
Mhinduro: Chikamu chekuchengetwa kwemvura ndechimwe chezvakakosha zviratidzo kuyera mhando ye methyl cellown cellever Kugadziridzwa kwemvura kunogona kudzivirira chiitiko chekurasikirwa kwesimba uye kupaza kwakakonzerwa nekunyanyisa kuoma uye zvisina kukwana hydration. Kuchengeta kwakanyanya kwemvura methyl cellelose ether pasi pemamiriro ekunze ndeimwe yezviratidzo zvakakosha kusiyanisa mashandiro emethyl cell. Mumamiriro ezvinhu akajairika, kuchengetwa kwemvura kwemvura yakawanda methyl cellulose ana ana vana vanoderera nekuwedzera kwekushisa. Kana tembiricha ika kusvika 40 ° C, kuchengetwa kwemvura kwemvura methyl methyl cellelose ana vanayo kwakaderedzwa kwazvo, izvo zvakakosha munzvimbo dzinopisa uye dzakaoma uye dzakaoma. Uye iyo yakatetepa-yakaomeswa kuvaka pakakwirira yezuva muzhizha ichave nekukanganisa kwakakura. Nekudaro, kugadzira kushaikwa kwekuchengetwa kwemvura kuburikidza neakakwira dosi kuchaita kuti yepamusoro visikoka yezvinhu zvakakonzerwa nenzvimbo yakakwirira, iyo ichakonzera kusawirirana kuvaka.

Kuchengetwa kwemvura kwakakosha kwazvo kuti uwedzere kuomesa maitiro ekuomesa kwemaminerari maelelly system. Pasi pechiito cheCellulose ether, iyo unyoro rinoburitswa kuimba yekutsvaira kana mhepo pamusoro penguva yakareba, saka simende kana gypsum nguva yakakwana yekudyidzana nemvura uye zvishoma nezvishoma yakaoma.
