Mhedzisiro ye cellulose ether pane putty powder

1. cellulose ether - cellulose ether predecessor

Cellulose ether ndiyo polysaccharide yakawanda kwazvo munyika nhasi.Nzvimbo huru dzechisikigo cellulose ikotoni, miti, zvirimwa zvemumvura, uswa uye zvichingodaro.Cotton ine 92-95% cellulose;Flax ine inenge 80% cellulose;Wood ine inenge 50% cellulose.

2, cellulose ether chimiro

Cellulose ether inonzi polysaccharide yakaoma ine zviuru zvezvikamu zveglucose mu molecule, chimiro chemakemikari ndeye (C6H10O5) N. D-glucose boka rinosungwa ne β - 1,4 glucoside bonds.

Matambudziko akajairika uye zvikonzero zvikuru zvekuramba kwemvura putty pamadziro emukati

Kazhinji nzira dzekugadzirisa dambudziko

Neutral putty:

Depowder: insufficient cementitious material, cellulose ether kuchengetwa kwemvura hakuna kukwana, calcium content ye heavy calcium yakaderera.

Kuita kwekuvaka: yakagadziridzwa ne bentonite uye starch ether.

Empty drum;Uye kunamatira kwemadziro kunokonzerwa nekusakwana.

Layering: interface yekugadzirisa.

Simba: Inogonawo kugadziriswa nekugadzika calcium poda.

Lime calcium putty:

Matambudziko haana chinhu chigubhu, depowder yellowing, kuvaka hakuna kunaka, depowder, stratification, kuputika, mushure mekukora;

Depowder: isina kukwana simende zvinhu, isina kukwana cellulose kuchengetedza mvura kana kusakwana kwekuwedzera, lime calcium haina kuchena.

Kuita kwakashata kwekuvaka: bentonite uye starch ether kugadzirisa.

Empty drum;Uye kusakwana kwekunamatira kwemadziro kunokonzerwa nekuwedzerwa kwakakodzera kwelatex powder.

Layering: interface yekugadzirisa.

Yellow: kusarudzwa kusina kunaka kwe cellulose ether.

Kutsemuka: kutsemuka kwehwaro kana kutsemuka kwakanyanyisa simba, kukoira zvakanyanya.

Mushure mekuwedzera: inorema calcium mvura inonwisa chiyero chakasiyana, zvinokurudzirwa kusarudza zero mvura yekunyura kana yakaderera kwazvo inorema calcium poda;Grey calcium ine isina kugezwa GaO.

Cement-based putty:

Matambudziko edhiramu isina chinhu, kuvaka hakuna kunaka, depowder, delamination, kuputika, kusakwana kwekudzivirira kwemvura, nhema coagulation;

Depowder: isina kukwana simende zvinhu, isina kukwana cellulose ether kuchengetedza mvura kana kusakwana kwekuwedzera.

Kuita kwakashata kwekuvaka: bentonite uye starch ether kugadzirisa.

Chigubhu chisina chinhu: uye kunamatira kwemadziro kunokonzerwa nekusakwana, zvine musoro kuwedzera kwe latex poda.

Layering: interface yekugadzirisa.

Yellow: Kusarudzika cellulose kusarudzwa.

Kusakwana kwekudzivirira kwemvura: isina kukwana latex poda uye isina kukwana simende zvinhu.

Kutsemuka: kutsemuka kwehwaro kana kuputika kwesimba rakawandisa, kukoira kwakanyanyisa, ne putty kuzadza gomba.

Nhema coagulation: sodium gluconate inogona kuwedzerwa kuwedzera nguva yekushanda.
