Ndeupi musiyano uripo pakati peHPMC E5 neE15?

HPMC (Hydroxypropyl Methylcellulose) imhando ye cellulose ether inoshandiswa mumhando dzakasiyana siyana. Iyo isiri-ionic, mvura-inonyungudika polima inotorwa kubva muselulosi, uye inoshandiswa seyakakora mumiriri, emulsifier, stabilizer, uye suspending agent. HPMC inowanikwa mumhando dzakasiyana siyana, imwe neimwe iine yayo yakasarudzika zvivakwa. HPMC E5 neE15 ndiwo maviri emagiredhi anonyanya kushandiswa eHPMC.

HPMC E5 igiredhi yakaderera viscosity yeHPMC, ine viscosity range ye4.0-6.0 cps. Inoshandiswa mumhando dzakasiyana dzekushandisa, senge machira, zvinonamira, uye sealants. Inoshandiswawo mukudya uye mishonga yekushandisa seyakakora, stabilizer, uye inomisa mumiririri. HPMC E5 inonyungudika mumvura inotonhora uye inopisa, uye inofambirana neyakasiyana siyana yeorganic solvents.

HPMC E15 ndeyepamusoro viscosity giredhi reHPMC, ine viscosity range ye12.0-18.0 cps. Inoshandiswa mumhando dzakasiyana dzekushandisa, senge machira, zvinonamira, uye sealants. Inoshandiswawo mukudya uye mishonga yekushandisa seyakakora, stabilizer, uye inomisa mumiririri. HPMC E15 inonyungudika mumvura inotonhora uye inopisa, uye inofambirana neyakasiyana siyana yeorganic solvents.

Musiyano mukuru pakati peHPMC E5 uye E15 ndiyo viscosity. HPMC E5 ine yakaderera viscosity pane HPMC E15, zvinoreva kuti haina viscous uye ine mutete kusachinja-chinja. Izvi zvinoita kuti HPMC E5 ikwane zvirinani kune maapplication anoda kutetepa kuenderana, senge mapeji uye zvinonamira. HPMC E15, kune rumwe rutivi, ine viscosity yakakwirira, iyo inoita kuti ive yakakodzera kune zvikumbiro zvinoda kusimba kwakakura, senge sealants uye zvigadzirwa zvekudya.

Mukuwedzera kune mutsauko we viscosity, HPMC E5 uye E15 inosiyanawo mukunyungudika kwavo. HPMC E5 inonyungudika mumvura inotonhora uye inopisa, nepo HPMC E15 inonyungudika chete mumvura inopisa. Izvi zvinoreva kuti HPMC E5 inogona kushandiswa mumashandisirwo anoda mhinduro yemvura inotonhora, nepo HPMC E15 inokodzera zvirinani zvikumbiro zvinoda mhinduro yemvura inopisa.

Pakupedzisira, HPMC E5 neE15 zvakare zvinosiyana mukuenderana kwavo neorganic solvents. HPMC E5 inofambirana neyakasiyana siyana yezvinonyungudutsa, nepo HPMC E15 inongoenderana nehuwandu hushoma hwezvinonyungudutsa. Izvi zvinoreva kuti HPMC E5 inokodzera zvirinani kune zvikumbiro zvinoda huwandu hwakasiyana hwezvinonyungudutsa, nepo HPMC E15 inokodzera zvirinani zvikumbiro zvinoda huwandu hushoma hwezvinonyungudutsa.

Mukupedzisa, HPMC E5 uye E15 magiredhi maviri akasiyana eHPMC, imwe neimwe iine yayo yakasarudzika zvivakwa. Musiyano mukuru pakati pavo ndeye viscosity, ine HPMC E5 ine yakaderera viscosity pane HPMC E15. Uye zvakare, HPMC E5 inonyungudika mumvura inotonhora uye inopisa, nepo HPMC E15 inonyungudika chete mumvura inopisa. Pakupedzisira, HPMC E5 inofambirana nemhando dzakasiyana-siyana dzezvinonyungudutsa, nepo HPMC E15 inongoenderana nehuwandu hushoma hwezvinonyungudutsa.
