Ka hopena o ka cellulose ether ma ka pauka putty

1. cellulose ether – ka mea i hana mua ʻia e ka cellulose ether

ʻEtera celluloseʻo ia ka polysaccharide nui loa ma ka honua i kēia lā. ʻO nā kumu nui o ka cellulose kūlohelohe he pulupulu, nā lāʻau, nā mea kanu wai, ka mauʻu a pēlā aku. Loaʻa i ka pulupulu he 92-95% cellulose; Loaʻa i ka olonā ma kahi o 80% cellulose; Loaʻa i ka lāʻau ma kahi o 50% cellulose.

2, ʻano hana o ka cellulose ether

He polysaccharide paʻakikī ka cellulose ether e loaʻa ana nā tausani o nā ʻāpana glucose i loko o ka molekala, ʻo ke ʻano kemika ʻo (C6H10O5) N. Hoʻopaʻa ʻia ka hui D-glucose e nā pilina β-1,4 glucoside.

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

Nā ʻano hoʻoponopono pilikia maʻamau

Putty kūlike ʻole:

Hoʻoheheʻe i ka pauka: ʻaʻole lawa ka mea sima, ʻaʻole lawa ka paʻa ʻana o ka wai cellulose ether, a haʻahaʻa ka nui o ka calcium o ka calcium kaumaha.

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

Pahu hakahaka; A me ka hoʻopili ʻana o ka paia i hana ʻia e ka lawa ʻole.

Papahele: hana hoʻopili.

Ikaika: Hiki ke hoʻololi ʻia ma ke kālai ʻana i ka pauka kalipuna.

ʻO ka putty calcium lime:

ʻO nā pilikia he pahu hakahaka, depowder yellowing, ʻaʻole maikaʻi ke kūkulu ʻana, depowder, stratification, cracking, ma hope o ka thickening;

Hoʻohemo i ka pauka: ʻaʻole lawa ka mea sima, ʻaʻole lawa ka paʻa ʻana o ka wai cellulose a i ʻole ka nui o ka hoʻohui, ʻaʻole maʻemaʻe ka lime calcium.

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

Pahu hakahaka; A me ka lawa ʻole o ka hoʻopili ʻana o ka paia i hoʻokumu ʻia e ka hoʻohui kūpono ʻana o ka pauka latex.

Papahele: hana hoʻopili.

Melemele: koho kūpono ʻole o ka cellulose ether.

Māwae: māwae kumu a paʻakikī loa paha ka ikaika o ka māwae, mānoanoa loa ka uhi.

Ma hope o ka mānoanoa ʻana: ʻokoʻa ka nui o ka omo ʻana o ka wai calcium kaumaha, ua ʻōlelo ʻia e koho i ka ʻole omo wai a i ʻole ka pauka calcium kaumaha haʻahaʻa loa; Loaʻa i ka calcium hina ka GaO i hoʻoheheʻe ʻole ʻia.

ʻO ka putty i hoʻokumu ʻia i ka sima:

Nā pilikia no ka pahu hakahaka, ʻaʻole maikaʻi ke kūkulu ʻana, depound, delamination, concretion, lawa ʻole ke kūpaʻa wai, coagulation wahaheʻe;

Hoʻohemo i ka pauka: lawa ʻole o ka mea sima, lawa ʻole ka paʻa ʻana o ka wai cellulose ether a i ʻole lawa ʻole ka nui o ka hoʻohui.

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

Pahu hakahaka: a me ka hoʻopili ʻana o ka paia i hana ʻia e ka lawa ʻole a me ka hoʻohui kūpono o ka pauka latex.

Papahele: hana hoʻopili.

Melemele: Koho pono ʻole ʻia o ka cellulose.

ʻAʻole lawa ka pale wai: lawa ʻole ka pauka latex a me nā mea sima ʻole.

Māwae: māwae kumu a i ʻole ka māwae ikaika loa, mānoanoa loa ka uhi, me ka putty e hoʻopiha i ka lua.

ʻO ka coagulation wahaheʻe: hiki ke hoʻohui ʻia ka sodium gluconate e hoʻolōʻihi i ka manawa hana.
