HydroxyPropyl methyl cellel celler Iyo yekutanga sosi ye cellulose yekugadzirwa kweHPMC iri kazhinji huni yehuni kana machira. Maitiro ekugadzira anosanganisira makemari kugadzirisa iyo cellulose kuburikidza nekutsvaga, kuunza hydroxypruppropyl uye methyl mapoka kune iyo cellulose backbone.

Kugadzirwa kweHPMC kunosanganisira matanho akati wandei:

1. Cellulose kubviswa:
   • Iyo cellulose inowanikwa kubva kune zvidyire zvinyorwa, kunyanya huni propp kana machira. Iyo cellulose inobviswa uye yakanatswa kuumba cellulose pulp.
2. Alkalization:
   • Iyo cellulose pulp inobatwa neAlkaline Solution, kazhinji sodium hydroxide (naoh), kuti udzore mapoka ehydroxyl paCellulose Chain.
3. Etera:
   • Kuwedzera ndiyo yakakosha nhanho mukugadzirwa kweHPMC. Iyo Alkalized Cellulose inoitwa neProcleene oxide (yeHydroxyPropyl mapoka) uye methyl chloride (ye methyl mapoka) kuunza aya mapoka emapoka kune iyo cellulose backbone.
4. Kusarerekera nekugeza:
   • Iyo inokonzerwa yakagadziridzwa cellulose, iyo yave iyo hydroxyprupyl methyl cellelose, dziratidzazve maitiro ekusarerekera kuti ubvise chero alkali yakasara. Izvo zvinobva zvachashambwa kuti ubvise kusvibiswa uye ne-zvigadzirwa.
5. Kuomesa uye kugaya:
   • Iyo yakagadziridzwa cellulose yakaomeswa kubvisa yakanyanyisa kunyorova uye inobva yabiwa mune yakanaka hupfu. Saizi yehukuru inogona kudzorwa zvichienderana nechinangwa chekushandisa.

Iyo inokonzeresa HPMC chigadzirwa chiratidzo chena kana kubva kune chena poda nehurema madhigirii ehydroxypropropyl uye methyl kutsiva. Izvo zvakananga zvivakwa zveHPMC, sekudaro sekusanzwisisa kwayo, viscosity, uye humwe hunhu hwekuita, zvinoenderana nedhigiri rekutsiva uye maitiro ekugadzira.

Izvo zvakakosha kuti uzive kuti HPMC ndeye Synthetic Polymer, uye ichitoshwa neyechisikigo cellumlose, iyo inokosha yemakemikari inogadziriswa panguva yekugadzira yekugadzira kuti iwane zvivakwa zvemaindasitiri akasiyana siyana.
