Ka hopena o ka cellulose ether ma ka pauka putty

1. cellulose ether - ka mea mua

ʻO ka cellulose ether ka polysaccharide nui loa i ka honua i kēia mau lā.ʻO nā kumu nui o ka cellulose maoli he pulupulu, lāʻau, mea kanu wai, mauʻu a pēlā aku.Aia ka pulupulu i ka 92-95% cellulose;Loaʻa i ka flax ma kahi o 80% cellulose;Aia ka lāʻau ma kahi o 50% cellulose.

2, ka hale etera cellulose

ʻO ka cellulose ether he polysaccharide paʻakikī i loaʻa nā tausani o nā ʻāpana glucose i loko o ka mole, ʻo ke ʻano kemika (C6H10O5) N. ʻO ka hui D- glucose i hoʻopaʻa ʻia e nā paʻa β - 1,4 glucoside.

ʻO nā pilikia maʻamau a me nā kumu nui o ka putty pale wai ma ka paia o loko

Nā ʻano hoʻoholo pilikia maʻamau

Putty kūʻokoʻa:

Depowder: lawa ʻole nā ​​mea cementitious, ʻaʻole lawa ka paʻa ʻana o ka wai cellulose ether, haʻahaʻa ka ʻike calcium o ka calcium kaumaha.

Hana hana: hoʻomaikaʻi ʻia e ka bentonite a me ka starch ether.

Pahu hakahaka;A hoʻopili ʻia ka pā ma muli o ka lawa ʻole.

Layering: kaʻina hana interface.

Ka ikaika: Hiki ke hoʻololi ʻia e ka helu ʻana i ka pauka calcium.

Lime calcium putty:

ʻO nā pilikia he pahu kaʻawale, ʻeleʻele ka depowder, maikaʻi ʻole ke kūkulu ʻana, depowder, stratification, māhā, ma hope o ka mānoanoa;

Depowder: lawa ʻole nā ​​mea cementitious, lawa ʻole ka mālama ʻana i ka wai cellulose a i ʻole ka nui o ka hoʻohui ʻana, ʻaʻole maʻemaʻe ka lime calcium.

Hana maikaʻi ʻole: bentonite a me ka starch ether e hoʻomaikaʻi.

Pahu hakahaka;A lawa ʻole ka pili o ka pā ma muli o ka hoʻohui kūpono o ka pauka latex.

Layering: kaʻina hana interface.

ʻO ka melemele: koho kūpono ʻole o ka cellulose ether.

Māhā: māwae kumu a mānoanoa paʻakikī paha, mānoanoa loa ka uhi ʻana.

Ma hope o ka mānoanoa: ʻokoʻa ka nui o ka absorption wai calcium kaumaha, makemake ʻia e koho i ka wai absorption a i ʻole ka pauka calcium haʻahaʻa haʻahaʻa;Loaʻa i ka calcium hina ka GaO i hoʻokahe ʻole ʻia.

Putty ma muli o ka sima:

ʻO nā pilikia no ka pahu kaʻawale, maikaʻi ʻole ke kūkulu ʻana, depowder, delamination, māhā, lawa ʻole ka wai, coagulation wahaheʻe;

Depowder: lawa ʻole nā ​​mea sima, lawa ʻole ka mālama ʻana o ka wai cellulose ether a i ʻole ka nui o ka hoʻohui.

Hana maikaʻi ʻole: bentonite a me ka starch ether e hoʻomaikaʻi.

Pahu hakahaka: a me ka hoʻopili ʻana i ka paia ma muli o ka lawa ʻole o ka hoʻohui kūpono o ka pauka latex.

Layering: kaʻina hana interface.

Melemele: Ke koho ʻana i ka cellulose kūpono ʻole.

ʻAʻole lawa ka pale wai: lawa ʻole ka pauka latex a lawa ʻole nā ​​mea cementitious.

Māhā: māwae kumu a māwae ikaika kiʻekiʻe paha, mānoanoa loa ka uhi, me ka putty e hoʻopiha i ka lua.

Coagulation hoʻopunipuni: hiki ke hoʻohui ʻia ka sodium gluconate e hoʻolōʻihi i ka manawa hana.
