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, he pai te hototahi ki te wai, ki 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. Te wai-atete me te hinuhinu I roto i te putty, ko te 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 hanga. wā. 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, he kakara, he reka, he 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, ki te gypsum, ki te peita, me etahi atu hei pupuri i te 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 pai o te hinu me te ester resistance, ina koa ko te pupuri wai me te hanga ahurei o te hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose Ko te taonga hanga kiriata o te cellulose i te mua i Haina.
