He aha nga painga o te cellulose?

Ko te Cellulose he momo cellulose ka tere ake te hanga me te whakamahi. He cellulose kore-pararopi i konatunatua etera i hangaia mai i te miro parakore i muri i te whakamaroketanga, ma te whakamahi i te propylene oxide me te methyl chloride hei kaiwhakawhanake etherification, me te maha o nga tauhohenga. Ko te tohu o te whakakapinga ko te tikanga 1.2~2.0. He rereke ona ahuatanga na te rereke o nga wahanga o nga waahanga tert-butyl me nga waahanga hydroxypropyl.

(1) He wairewa te Cellulose i roto i te wai matao, a ka uaua te memeha ki te wai kohua. Engari he nui ake te pāmahana o te gelatinization i roto i te wai kohua i tera o te carboxycellulose. Ko te ahua memeha i roto i te wai matao ka tino pai ake ki te whakarite ki te carboxycellulose.

(2) Ko te viscosity o te cellulose e pa ana ki te rahi o te papatipu ngota whanaunga, me te nui ake o te papatipu ngota, ka nui ake te viscosity. Ka pa ano te pamahana ki tona pokey, ka piki te pāmahana, ka heke te pokey. Engari he iti ake te kino o tona pokey teitei me te pāmahana teitei i te carboxycellulose. Ka noho pūmau tana wairewa wai ka penapena ki te pāmahana rūma.

(3) Ko te pupuri wai me te wairewa o te cellulose kei roto i tona nui taapiri, te pokey, me etahi atu, a ko tona tere pupuri wai i raro i te nui o te taapiri he nui ake i tera o te carboxycellulose.

(4) Cellulose he ātete ki te waikawa me te alkali, a he tino pumau tona otinga i roto i te awhe o te pH = 2 ~ 12. Karekau he awe nui o te konumohe konumohe hauota me te slurry kotakota i runga i ona taonga, engari ka taea e te alkali te whakatere i te reiti rewa me te whakapai ake i tona pokey. He pono te Cellulose ki nga tote waikawa noa, engari ka nui te kukū o te wairewa tote, ka piki ake te pokey o te otinga cellulose.

(5) Ka taea te whakamahi i te Cellulose me nga polymers wairewa-wai hei hanga i tetahi otinga wai-a-wai me te teitei. Pērā i te whakaehunga kiriaku, tapioka māngaro ether, kāpia huawhenua, etc.

(6) He kaha ake te parenga o te pūmua whākōkī i te carboxycellulose, ā, he iti ake te rewa o tana wairewa wai e te whākōkī i te carboxycellulose.

(7) Ko te piri o te cellulose ki te hanga moata ciment he teitei ake i tera o te carboxycellulose.
