Focus on Cellulose ethers

Whakamahia te hydroxypropyl methylcellulose ki te u ki etahi taonga

Ko te Hydroxypropylmethylrubicin (HPMC) he rauemi cellulosic, he penupenu, he miro ranei ka taea te whakamahi hei whakamahine i te penupenu rakau. I mua i te whakamaaramatanga me te mahi whakamaaramatanga me whakangaro. Ka taea e te kino o te miihini te whakangaro i te hanganga whakahiato o te rauemi cellulose pepa, na reira ka whakaiti i te polymerization me te tioata, te whakanui ake i te waahanga mata motuhake, na te whakanui ake i te matrix ka taea te macromolecular ternary me te cellulose.

Ka whakamahia te Hydroxymethylcellulose hei tïpako i roto i te hanga hinu. Ka taea e te tauira whaipainga te whakaoti i te whakamahinga o te huka, te whakapai ake i te tere o te whakamahinga o nga rawa, te whakaiti i te toenga o te tïpako i roto i te wai FERMENTATION, me te whakaiti i te utu mo te maimoatanga wai para. Ko nga ahuatanga o te ranunga he pai ki te arotautanga o te puranga, te whangai-whanga me nga tukanga FERMENTATION tonu, te karo i te raweke o nga waahanga reo me nga reiti waimeha, me te whakahaere hoki i te whakatikatika o nga tikanga FERMENTATION. I te mea he rite te mahi a te HPMC ki etahi atu etera wairewa-wai, ka taea te whakamahi hei kaihoko hanga-kiriata, hei whakakao, hei whakaehunga me te whakapumau mo te peita taherapa me te peita kapia wairewa-wai, me te pai o te whakakakahu i te kakahu, te paninga rite me te piri Arotahi ki runga. te whakapai ake i te mahanga o te mata, te pumau o te waikawa-turanga me te hototahi ki nga poaka konganuku.

Ko te tito o te hydroxypropylmethylcellulose (HPMC) he raruraru, engari i roto i te kaupapa, engari te ngaronga o te tïpako, te turanga..etherification, te whakakore

Ko te whakaora mai i nga kaihoko na roto i te centrifugation, te horoi, te whakamaroke me te pa ki ia taiao, he nui nga pukenga me nga matauranga.

Ko nga taputapu awhina me nga mana-maataki ka awhina i te kounga o te hua me te punaha whakaputa pono. Ka pa ki te nui o te wai i roto i te moata whakamaroke-maroke o te hypromellose hydroxypropyl methylcellulose etera moata pupuri-wai hei whakatairanga i te whakamakuku tonu o te sima, te kumete me te tïpako hei whakanui ake i te wa piri.

He painga nui o te pupuri wai, te pupuri wai, te pupuri makuku ko te paura putty, te piri me nga mahi whakahinuhinu. Ka whakamahia nuitia i roto i te ahumahi hanga, te ahumahi peita me te maha atu o nga umanga, he mea nui te hydroxypropyl methylcellulose mo tete hanga hydroxypropyl methylcellulose. Ko te pāmahana waiariki he tino teitei ake i tera o te methylcellulose. He iti te paanga o te kotakota me te houra ki te mahi, engari ka taea te whakatere i te whakakorenga o te matrix me te whakanui ake i te pokey. A, no te polyvinyl waipiro, māngaro ether, kapia huawhenua me te hydroxypropyl methylcellulose peita, me ētahi atu, te otinga kararehe o te hanganga i runga ake. I te wa e whakamahi ana i te kumete, te gypsum, te paura putty me etahi atu mea hei whakapiri, ka taea te whakapai ake i te mahi me te whakaroa i te waa mahi. Ka taea te whakamahi mo te whakapaipai, te whakapiri i nga taera, te mapere, te kirihou me te whakaiti i te whakamahinga o te kakau teka sima. E kore e tere rawa te pakaru o te wai-pupuri i muri i te whakamaroketanga, ka pai ake te kaha i muri i te whakamaroketanga.
