He iti noa te tāpiri o te cellulose ether i roto i te moata paura maroke o te hydroxypropyl methylcellulose, engari ka taea e ia te whakapai ake i te mahi a te moata mākū, ā, ko ia te tāpiri matua e pā ana ki te mahi hanga o te moata.
Hydroxypropyl methylcellulose Ko te cellulose ether e whakamahia ana i roto i te moata paura maroke ko te hydroxypropyl methylcellulose ether (HPMC). I roto i ngā uku honikoma hou, ka taea e ia te whakahinuhinu i te paraikete. I roto i te umanga paninga, ka taea te whakamahi hei whakamātotoru, hei whakamarara me te whakaū i roto i te umanga paninga, ā, he pai te hototahi ki te wai, ki ngā whakarewa waro rānei. Hei tango peita. Tānga waituhi: Ka whakamahia hei whakamātotoru, hei whakamarara me te whakaū i roto i te umanga waituhi, ā, he pai te hototahi ki te wai, ki ngā whakarewa waro rānei. Kirihou: Ka whakamahia hei kaihanga tuku, hei whakangawari, hei hinu whakahinuhinu, me ētahi atu. Polyvinyl chloride: Ka whakamahia hei whakamarara i roto i te hanga polyvinyl chloride, ā, ko ia te kaihoko āwhina matua mō te whakarite PVC mā te whakatārewatanga polymerization. Hydroxypropyl methylcellulose Ētahi atu: Ka whakamahia whānuitia hoki tēnei hua i roto i te hiako, ngā hua pepa, te tiaki hua me te huawhenua me ngā ahumahi kakahu.
Ko te HPMC i roto i te moata paura maroke te mahi nui ki te pupuri wai, ki te whakamātotoru me te whakapai ake i te mahi hanga. Mā te pupuri wai nui o te moata hanga me te onepu parai ka taea te whakamakuku katoa i te sima me te whakanui ake i te kaha here. I te wa ano, ka taea e ia te whakanui ake i te kaha kume me te kaha kutikuti, ka whakapai ake i te hua hanga me te whakapai ake i te pai o te mahi. Ātete wai me te hinuhinu I roto i te putty, ko te hydroxypropyl methylcellulose cellulose ether te mahi nui ki te pupuri wai, te here me te whakahinuhinu, te karo i ngā kapiti me te maroke i puta mai i te nui o te ngaronga wai, me te whakanui ake i te piri o te putty me te whakaiti i te wa hanga. Ko te āhuatanga totoro waenga ka maeneene ake te hanga. I roto i ngā hua raupapa gypsum, ko te hydroxypropyl methylcellulose cellulose ether te mahi nui ki te pupuri wai me te whakahinuhinu, ā, i te wa ano he pānga whakaroa, e whakaoti ana i ngā raruraru o te pakaru o te pahu me te ngoikore o te kaha tuatahi i te wa hanga. , ka taea te whakaroa i ngā haora mahi. Ko te kaihoko atanga Hydroxypropyl methylcellulose te nuinga e whakamahia ana hei whakamātotoru, ka taea te whakapai ake i te kaha kume me te kaha kutikuti, te whakapai ake i te paninga mata, te whakarei ake i te piri me te kaha here. Ngā Āhuatanga: He paura mā, he paura kōwhai paku rānei tēnei hua, kāore he kakara, kāore he reka, ā, kāore he paitini. Ka taea te pupuri wai me te whakanui ake i te kaha. , te paura putty, ētahi atu rauemi hanga rānei hei here hei whakapai ake i te horapa me te whakaroa i te wā mahi. Ka taea te whakamahi hei tāera whakapiri, hei māpere, hei whakapaipai kirihou, hei whakapakari whakapiri, ā, ka taea hoki te whakaiti i te nui o te sima. Mā te mahi pupuri wai o te HPMC ka ārai i te pakaru o te paru nā te tere rawa o te maroke i muri i te tono, ā, ka whakanui ake i te kaha i muri i te whakapakeketanga. Te hanga uku: He whānuitia te whakamahinga hei here i roto i te hanga hua uku. Te pumau o te PH: He pumau te matotoru o te wairewa o tēnei hua i roto i te awhe PH3.0-11.0. Te pānga pupuri wai: He pai ki te wai te Hydroxypropyl methylcellulose, ā, he tino matotoru tōna wairewa. Ka tāpirihia te Hydroxypropyl methylcellulose (HPMC) ki te moata, te gypsum, te peita, me ētahi atu hei pupuri i te pupuri wai nui i roto i te hua. Te pupuri āhua: Ki te whakatauritea ki ētahi atu polymer wairewa-wai, he āhuatanga viscoelastic motuhake tō te wairewa o tēnei hua. Mā te tāpiri atu ka taea te whakapai ake i te kaha pumau-āhua o ngā hua uku kua whakaputahia, me ētahi atu.
Te whakahinuhinu o te hydroxypropyl methylcellulose (HPMC): Mā te tāpiri i tēnei hua ka taea te whakaiti i te tauwehenga waku me te whakapai ake i te whakahinuhinu o ngā hua uku me ngā hua sima kua whakaputahia. Ngā āhuatanga hanga-kiriata: Ka taea e tēnei hua te whakaputa i ngā pepa pakari, ngāwari, me te mārama me te ātete pai ki te hinu me te ester, inā koa te pupuri wai me te hanganga ahurei o te hydroxypropyl methylcellulose (HPMC), te hydroxypropyl methylcellulose. Ko te āhuatanga hanga-kiriata o te cellulose kei mua i Haina.
