Ndeipi pfungwa yekutanga yetsvina eTher?
Mhinduro: Starch Ethere inonyanya kushandiswa mune yekuvaka motokari, iyo inogona kukanganisa kuwirirana kwemotokari yakavakirwa pane gypsum, simende uye lime, uye shandura kuvaka uye sag kudzikisira kwemutya. Starch anaitinhi vanowanzo shandiswa pamwe chete neisina-kushandurwa uye yakagadziridzwa cellulose ma cellouter. Izvo zvakakodzera kune ese asina kwaakarerekera uye alkaline masystem, uye inoenderana nekuwedzera kwekuwedzera muGypsum uye simende zvigadzirwa (senge surfers
Hunhu hwehunhu hwe strar ether zvinonyanya kunyepa mukati:
(1) kuvandudza Sag kuramba;
(2) kuvandudza kuchengetedzwa;
(3) yakakwirira moter.
Ndeipi basa guru renhether ether mune gypsum-based yakaoma mota?
Mhinduro: Starch Ethere ndeimwe yekuwedzera mainini yekuwedzera kweiyo yakaoma poda dhiri. Inogona kuenderana nevamwe vanowedzera. Inoshandiswa zvakanyanya mumatope anoshongedzwa, gadziriso yemauto, mumukati mekusvitsa madziro uye anokonzerwa nemauto, zvakakwaniriswa kuti zvimedu kana kuti spect Inoshanda seinotevera:
. Kuwedzera huwandu hwakakodzera hwehunhu hwakatora methyl celler celler cell
(2.
.
Ndezvipi zvinhu zvinoshandiswa uye nzira dzekuchengetedza dzestrar ethether?
Mhinduro: Inogona kushandiswa seyakagashira yezvinhu zvimeser-based zvigadzirwa, zvigadzirwa zveGypsum-based zvigadzirwa uye ash-calcium zvigadzirwa.
(1) Zvakanakira uye zvikumbiro:
a. Iyo ine simba rakakura pana duri, rinogona kukurumidza kupfidza, uye rinogona kuita zvakanaka.
b. Dosage idiki, uye dosage yakaderera inogona kuzadzisa zvakakura;
c. Kuvandudza kugona kweAnti-slide yegomba rakabikwa;
d. wedzera nguva yakavhurika yezvinyorwa;
e. Kuvandudza mashandiro ekushanda kwezvinhu uye ita kuti kuvhiyiwa kwakanyarara.
(2) kuchengetedza:
Chigadzirwa chinobatwa nemunyoro uye chinofanira kuchengetwa munzvimbo yakaoma uye inotonhorera mune yekutanga kurongedza. Zvakanaka kuishandisa mukati memwedzi gumi nemaviri. (Zvinokurudzirwa kushandiswa pamwe chete neyekumusoro-viscosity cell
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.
