Kuchena kwehydroxypropyl methylcellulose mukuvaka dhaka rekudzivirira uye putty powder inobata zvakananga kunaka kwekugadzirwa kweinjiniya, saka ndezvipi zvinhu zvinokanganisa kuchena kwehydroxypropyl methylcellulose?Rega ndikupindure mubvunzo uyu.
Mukugadzirwa kwehydroxypropyl methylcellulose, iyo yakasara okisijeni mu reactor ichaita kuti kuderedzwa kwehydroxypropyl methylcellulose uye kuderedza uremu hwema molecular, asi iyo yakasara okisijeni inogumira, chero isina kuoma zvakanyanya kubatanidza mamorekuru akaputsika Njodzi.Iyo inonyanya kukosha yekuzara kwemvura ine zvakawanda zvekuita nezviri mukati mehydroxypropyl.Mamwe mafekitari anongoda kuderedza mutengo uye mutengo, asi haadi kuwedzera zvirimo zvehydroxypropyl, saka mhando haigone kusvika pamwero wezvigadzirwa zvekunze zvakafanana.
Mwero wekuchengetedza mvura wehydroxypropyl methylcellulose zvakare ine hukama hukuru nehydroxypropyl, uye kune iyo yese maitiro maitiro, hydroxypropyl inotarisawo mwero wekuchengetedza mvura wehydroxypropyl methylcellulose.Mhedzisiro yealkalization, chiyero chemethyl chloride uye propylene oxide, kusungirirwa kwealkali uye chiyero chemvura kune yakacheneswa donje zvese zvinotarisa kushanda kwechigadzirwa.
Hunhu hwezvakagadzirwa, mhedzisiro yealkalization, chiyero chekutonga kwemaitiro, chiyero chezvinonyungudutsa uye mhedzisiro yekusagadzikana zvese zvinotaridza kunaka kwehydroxypropyl methylcellulose, uye imwe hydroxypropyl methylcellulose inogadzirwa kuti inyunguduke Pashure, yaive makore sekuwedzera. mukaka, mamwe aive muchena semukaka, mamwe ariyero, uye mamwe aive akajeka uye akajeka.Kana iwe uchida kuzvigadzirisa, gadzirisa kubva pane zviri pamusoro apa.Dzimwe nguva acetic acid inogona kukanganisa zvakanyanya kutapurirana kwechiedza.Zvakanakisisa kushandisa acetic acid mushure mekuderedzwa.Mhedzisiro huru ndeyekuti mhinduro yacho inomutswa zvakaenzana uye kana system reshiyo yakagadzikana (zvimwe zvinhu zvine unyoro uye zvirimo hazvina kugadzikana, senge kudzokorodza zvinonyungudutsa).Muchokwadi, Zvinhu zvakawanda zviri kutamba.Nekugadzikana kwemidziyo uye kushanda kwevashandi vakanyatsodzidziswa, zvigadzirwa zvinogadzirwa zvinofanira kunge zvakanyatsogadzikana.Chiedza chekufambisa hachizopfuure huwandu hwe ± 2%, uye kutsiva kufanana kwemapoka anotsiva kunofanirwa kudzorwa zvakanaka.Panzvimbo pekufanana, kutapurirana kwechiedza kungave kwakanaka.
