Iyo rheology uye kuenderana kwehydroxypropyl methylcellulose (HPMC) uye hydroxypropyl starch (HPS) macomplexes anoita basa rakakosha mumaindasitiri akasiyana, anosanganisira emishonga, chikafu, zvizorwa, uye kuvaka.Kunzwisisa kupindirana pakati pemapolymer maviri aya kwakakosha pakugadzirisa mashandiro avo uye kugadzira zvigadzirwa zvitsva.Iri bepa rine chinangwa chekuongorora rheological zvivakwa uye kuenderana kweiyo HPMC/HPS yakaoma.
Rheological Properties:
Rheology chidzidzo chekuti zvinhu zvinokanganisa sei uye zvinoyerera pasi pesimba rekunze kwemasimba.Panyaya yeHPMC/HPS yakaoma, iyo rheological zvivakwa zvinotarisa viscosity, gelation maitiro, uye yakazara kuyerera zvimiro zvepolymer musanganiswa.Iyo rheological maitiro eiyo yakaoma inogona kukanganiswa nezvinhu zvakaita se polymer concentration, molecular weight, tembiricha, uye shear rate.
Kuenderana kweHPMC uye HPS:
Kuenderana pakati peHPMC neHPS kwakakosha kuti uve nechokwadi chekuumbwa kwenzvimbo dzakagadzikana dzine zvinhu zvinodikanwa.Kuenderana kunoreva kugona kwemapolymer maviri kana anopfuura kusanganisa uye kugadzira homogeneous system pasina kupatsanurwa kwechikamu kana kurasikirwa kwekuita.
Zvinhu zvinokanganisa rheology uye kuenderana:
Polymer ratio: The reshiyo yeHPMC kune HPS mune yakaoma inogona kukanganisa zvakanyanya rheological maitiro uye kuenderana.
Molecular weight: The molecular weight of HPMC neHPS inokanganisa rheology uye kuwirirana kwezvakaoma.
Tembiricha: Iyo tembiricha iyo yakaoma inogadzirirwa uye yakaedzwa inokanganisa maitiro ayo e rheological.
Shear Rate: Iyo shear rate inoshandiswa panguva yekuyedzwa kana kugadzirisa inogona kukanganisa rheological zvimiro zveHPMC / HPS yakaoma.Yakakwira shear mitengo inogona kutungamirira kushear-kuonda maitiro, uko viscosity inoderera nekuwedzera shear rate.
Applications:
Iyo rheology uye kuenderana kweiyo HPMC / HPS yakaoma ine mhedzisiro yakakosha mumaindasitiri akasiyana siyana. seyakakora mumiriri, stabilizer, kana emulsifier.Muzvinhu zvekuvaka, macomplexes anogona kuvandudza kushanda uye kunamatira kwemasisitimu esimende.
Rheology uye kuenderana kweHPMC/HPS complexes zvinhu zvakakosha pakugadzirisa mashandiro avo kune akasiyana maapplication. uye budiriro munzvimbo ino inogona kutungamira mukusikwa kwezvigadzirwa zvitsva zvine mashandiro akakwenenzverwa uye mashandiro ari nani mumaindasitiri mazhinji.
