Hydroxypropyl methylcellulose i roto i te moata paura maroke, he iti rawa te taapiri o te cellulose ether, engari ka taea te whakapai ake i te mahi o te kumete maku, a ko te taapiri matua e pa ana ki te mahi hanga o te moata.
Hydroxypropyl methylcellulose Ko te ether cellulose e whakamahia ana i roto i te moata paura maroke ko te nuinga o te hydroxypropyl methylcellulose ether (HPMC). I roto i nga taonga hou o te honikoma, ka taea e ia te whakahinuhinu ki te waatea. I roto i te ahumahi whakakikorua, ka taea te whakamahi hei whakamaarama, whakamararatanga me te whakapumau i roto i te umanga whakakikorua, he pai te hototahi ki roto i te wai, i nga whakarewa pararopi ranei. Hei tango peita. Te tuhi waituhi: Ka whakamahia hei whakamaaratanga, hei whakamararatanga me te whakapumau i roto i te umanga waituhi, a he pai te hototahi ki roto i te wai, i nga whakarewa pararopi ranei. .Plastic: whakamahia rite hanga kaihoko tuku, ngohengohe, whakahinuhinu, me ētahi atu Polyvinyl pūhaumāota: Kei te whakamahia te reira rite te dispersant i roto i te hanga o te polyvinyl pūhaumāota, a ko te kaihoko pŭpŭ tauturu matua mo te whakarite PVC mā te whakatārewatanga polymerization. Hydroxypropyl methylcellulose Ētahi atu: Kei te whakamahia whānuitia tenei hua i roto i te hiako, hua pepa, hua me te tiaki huawhenua me te ahumahi pueru.
Ko te HPMC i roto i te kumete paura maroke te nuinga o te mahi ki te pupuri i te wai, te whakapakeke me te whakapai ake i nga mahi hanga. Ko te nui o te pupuri i te wai o te kumete hanga me te kirikiri raima ka taea te tino whakamakuku i te sima me te tino whakanui ake i te kaha here. I te wa ano, ka taea e ia te whakanui ake i te kaha o te kaha me te kaha o te kutikuti, te whakapai ake i te painga o te hanga me te pai ake o te mahi. Wai-ātete me te hinuhinu I roto i te putty, hydroxypropyl methylcellulose cellulose ether te nuinga o te mahi ki te pupuri i te wai, te honohono me te whakahinuhinu, te karo i nga kapiti me te matewai na te nui o te mate o te wai, i te wa ano ka whakarei ake i te piri o te putty me te whakaiti i te wa hanga. Ko te ahua o te sag waenga ka ngawari te hanga. I roto i nga hua raupapa gypsum, ko te hydroxypropyl methylcellulose cellulose ether te nuinga o te mahi ki te pupuri i te wai me te whakahinuhinu, a, i te wa ano he paanga whakamuri, e whakaoti ana i nga raru o te pakaru o te pahū me te kore o te kaha tuatahi i te wa o te hanga. , ka taea te whakaroa atu i nga haora mahi. Ko te kaihoko atanga Hydroxypropyl methylcellulose te nuinga o te whakamahi hei kaitao, ka taea te whakapai ake i te kaha me te kaha kutikuti, te whakapai ake i te paninga o te mata, te whakarei ake i te whakapiri me te kaha hononga. Ngā Āhuatanga: He paura mā, paku kōwhai rānei tēnei hua, kāre he kakara, kore reka me te kore paitini. Te pupuri wai me te kaha ake. , paura putty me etahi atu mea hanga whare hei here ki te whakapai ake i te horahanga me te whakaroa i te wa mahi. Ka taea te whakamahi hei whakapiri tile, mapere, whakapaipai kirihou, whakapiri whakakaha, ka taea hoki te whakaiti i te nui o te ciment. Ko te mahi pupuri wai o te HPMC ka aukati i te pakaru mai i te pakaru na te mea he tere rawa te whakamaroke i muri i te tono, me te whakanui ake i te kaha i muri i te whakapakeke. Te hanga uku: Kei te whakamahia nuitia hei here ki te hanga hua uku. PH pūmautanga: Ko te pokey o te otinga wai o tenei hua he āhua pūmau i roto i te whānuitanga o PH3.0-11.0. Te painga o te pupuri i te wai: Ko te Hydroxypropyl methylcellulose he hydrophilic me tana wairewa wai he tino poiketa. Ko te Hydroxypropyl methylcellulose (HPMC) ka taapirihia ki te kumete, te gypsum, te peita, me etahi atu hei pupuri i te pupuri wai nui i roto i te hua. Te pupuri i te ahua: Ka whakatauritea ki etahi atu polymers wairewa-wai, ko te wairewa wai o tenei hua he ahuatanga viscoelastic motuhake. Ka taea e tana taapiri te whakapai ake i te kaha o te ahua-kore o nga hua karaima kua whakakorehia, me era atu.
Te whakahinuhinu o te hydroxypropyl methylcellulose (HPMC): Ko te taapiri i tenei hua ka whakaiti i te whakarea waku me te whakapai ake i te whakahinuhinu o nga hua uku me nga hua ciment. Nga taonga hanga kiriata: Ka taea e tenei hua te whakaputa i nga pepa kaha, ngawari, me te maamaa me te hinu pai me te kaha o te ester, ina koa ko te pupuri i te wai me te hanga ahurei o te hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose Ko te taonga hanga kiriata o te cellulose i mua i Haina.
