Te Whakamahinga o te Cellulose Ether

I roto i te hanganga o te moata paura maroke,te etera celluloseHe tāpiringa nui te mea nei, he iti noa te nui o te tāpiri, engari ka taea e ia te whakapai ake i te mahi whakaranu me te hanga o te moata. Ki te kī māmā noa, ko te nuinga o ngā āhuatanga whakaranu mākū o te moata e kitea ana e te kanohi tahanga ka whakaratohia e te cellulose ether. He matū i ahu mai i te cellulose i whiwhihia mā te whakamahi i te cellulose mai i te rakau me te miro, ka tauhohe ki te houra kautika, kātahi ka whakaeterehia ki te kaihoko whakaetere.

Ngā momo etera cellulose

A. Te hauwaiporoporo metila (HPMC), he mea hanga te nuinga ki te miro kua parakorehia he tino parakore hei rauemi mata, ka whakaeterehia motuhaketia i raro i ngā āhuatanga kawakore.
B. Te Hydroxyethyl methylcellulose (HEMC), he etera cellulose kore-ionic, he paura ma te āhua, kāore he kakara, kāore hoki he reka.
C. Te pūhui hauwaioraitiri (HEC), he matū horoi kore-ionic, he mā te āhua, kāore he kakara, kāore he reka, he paura ngāwari te rere.

Ko ngā mea o runga ake nei ko ngā etera cellulose kore-ionic, me ngā etera cellulose ionic (pērā i te carboxymethyl cellulose CMC).

I te wā e whakamahia ana te moata paura maroke, nā te mea he koretake te cellulose ionic (CMC) i te aroaro o ngā ion konupūmā, he onge te whakamahinga i roto i ngā pūnaha whakapūkara kore-waro me te sima me te raima kua whakamaroketia hei rauemi sima. I ētahi wāhi i Haina, ko ētahi putty pakitara o roto i tukatukahia me te māngaro whakarerekētia hei rauemi sima matua me te paura Shuangfei hei whakakī ka whakamahi i te CMC hei whakamātotoru. Heoi, nā te mea he ngāwari tēnei hua ki te harore, ā, kāore e ātete ki te wai, ka āta tangohia e te mākete. I tēnei wā, ko te cellulose ether e whakamahia nuitia ana i Haina ko te HPMC.

Ko te nuinga o te wā ka whakamahia te cellulose ether hei kaihoko pupuri wai me te whakamātotoru i roto i ngā rauemi sima.

Mā tōna mahi pupuri wai ka ārai i te mimiti nui o te wai i te papa, ā, ka ārai hoki i te mimiti o te wai, kia nui ai te wai o te sima ina makuku. Hei tauira, ko te mahi whakapiripiri. Ina pania te paru sima noa ki te mata o te papa, ka tere te mimiti o te nui o te wai mai i te paru, ka ngaro ngāwari te wai e hiahiatia ana mō te makuku i te paparanga paru sima e tata ana ki te paparanga turanga. , nō reira, ehara i te mea kāore e taea te hanga i te kirikiri sima me te kaha piri ki te mata o te papa, engari he ngāwari hoki ki te piko me te mimiti wai, nō reira, he ngāwari te taka o te paparanga paru sima mata. Ina angiangi te kirikiri i pania, he ngāwari hoki te hanga kapiti i roto i te kirikiri katoa. Nō reira, i ngā mahi whakapiripiri mata o mua, ko te wai te tikanga hei whakamakuku i te papa i te tuatahi, engari ehara i te mea he mahi nui, he roa hoki tēnei mahi, engari he uaua hoki ki te whakahaere i te kounga o te mahi.

I te nuinga o te wā, ka piki ake te pupuri wai o te paru sima i te pikinga ake o te nui o te cellulose ether. Ka nui ake te matotoru o te cellulose ether kua tāpirihia, ka pai ake te pupuri wai.

Haunga te pupuri wai me te whakamātotoru, ka pā anō hoki te cellulose ether ki ētahi atu āhuatanga o te moata sima, pērā i te whakaroa, te pupuri hau, me te whakanui ake i te kaha o te hononga. Ka whakaroa te cellulose ether i te tukanga whakatakoto me te whakapakeke o te sima, ā, ka roa ake te wā mahi. Nō reira, i ētahi wā ka whakamahia hei whakapūmau.

I te whanaketanga o te moata maroke-ranu,te etera cellulosekua noho hei ranunga moata sima nui. Heoi, he maha ngā momo me ngā whakaritenga o te cellulose ether, ā, kei te rerekē tonu te kounga i waenga i ngā puranga.
