HydroxyPropyl methylcellose (HPMC) inzvimbo yezvinhu zvakasiyana-siyana nehuremu hwakawanda hwekushandisa mumasango, kusanganisira mishonga, chikafu, kuvaka, uye cosmetics, uye cosmetics, uye cosmetics. Paunenge uchifunga nezvenzvimbo yayo yekunyora, zvakakosha kuti ubvise muhunhu hwayo maererano nekudziya shanduko, kugadzikana kwekunyora, uye chero zviitiko zvine hukama.
Kugadzikana kweTermal: HPMC inoratidzira yakanaka yekukasira kudzikama pamusoro peyakaipisisa tembiricha. Izvo zvinowanzoitika pamhepo dzakakwirira tembiricha, kazhinji pamusoro pe200 ° C, zvichienderana neyakaomeswa uremu, degree rekutsiva, uye zvimwe zvinhu. Maitiro ekushambadzira anosanganisira kuchena kweiyo cellulose backbone uye kusunungurwa kwezvinhu zvisina basa zvechidhori.
Girazi transition tembiricha (TG): Kufanana nePolymers akawanda, HPMC iri kushandurwa kwegirazi kubva mugirazi kuenda kuRabhay State nekuwedzera tembiricha. Iyo tg yeHPMC inosiyana zvichienderana nedanho rayo rekutsiva, zvinyoro-nyoro uremu, uye zvinyoro-nyoro. Kazhinji, zvinobva pamakumi mashanu c. Pamusoro TG, HPMC inowedzera inoshanduka uye inoratidza kuwedzera molecular kufamba.
Inline polling point: yakachena HPMC haina nzvimbo yakasarudzika yekunyungudika nekuti inzvimbo yeAmorphous polymer. Nekudaro, iyo inorema uye inogona kuyerera pakukwirira kwekushisa. Kuvapo kwekuwedzera kana kusvibiswa kunogona kukanganisa maitiro ayo ekunyungudika.
Thermal Discount: HPMC ine yakaderera yekubatanidza kubatana kuenzaniswa nesimbi uye vamwe vamwe polymers. Ichi chivakwa chinoita kuti zviite kuti zvikurumidze zvikumbiro zvinoda kuti inyongwe yekuuraya, senge mumapiritsi emishonga kana zvekuvaka.
Kuwedzera kwekuwedzera: Senge vazhinji polymers, hpmc inowedzera kana ichipiswa uye zvibvumirano painenge ichitonhorera. Iyo coefficient yekuwedzera kwekuwedzera (cte) yeHPMC inoenderana nezvinhu senge zvimiro zvemakemikari uye mamiriro ekugadzirisa. Kazhinji, ine cte mune huwandu hwezana zana kusvika 300 ppm / ° C.
Kupisa simba: Iyo yekupisa simba reHPMC inokurudzirwa neyakagadziriswa ma molecular chimiro, degree rekutsiva, uye zvinyoro-nyoro. Izvo zvinowanzoitika kubva ku1.5 kusvika ku2,5 j / g ° c. Madhigirii epamusoro ekutsiva uye zvinyoro-nyoro zvinowanzowedzera kuwedzera simba rekupisa.
Kushatisa kwehunyanzvi: Kana uchinge wasimbiswa kupisa kwenguva refu kwenguva yakareba, HPMC inogona kukurumidza kudzvinyirira. Maitiro aya anogona kukonzera shanduko mune yayo makemikari chimiro, inotungamira kurasikirwa kwezvivakwa senge viscosity uye mechaniki simba.
Kuwedzeredza Kusvirira: HPMC inogona kushandurwa kuti isasimudzire iyo yayo inobata yekubatanidza kune chaiyo mafaro. Kusanganisira mafirita kana ekuwedzera, senge simbi zvimiti kana kabhoni nanotubes, inogona kuvandudza kupisa kuendesa zvivakwa, zvichiita kuti zviite kuti zviite zvakaringana zvekushandisa manejimendi.
Zvikumbiro: Kunzwisisa iyo inowedzera zvinhu zveHPMC inokosha yekugadzirisa kushandiswa kwayo mune dzakasiyana siyana application. Mune mishonga yemishonga, inoshandiswa seye binder, firimu raimbova, uye rakaburitswa-kuburitswa mumiriri mukuumbwa kwehwendefa. Mukuvaka, inoshandirwa muzvinyorwa zve coment-based yekuvandudza basa, kudenha, uye kuchengetwa kwemvura. Mune zvekudya uye zvizoro, zvinoshanda sedhizimusi, stabilizer, uye emulsifier.
HydroxyPropyl methylcellose (HPMC) inoratidzira huwandu hwenzvimbo dzekutora dzinoita kuti zviite kuti zviite kuti zviite kuti zviite zvishandiso zvakasiyana-siyana maindasitiri. Yayo inogadziriswa, girazi rinoshandura tembiricha, rinodziya dhairi, uye humwe hunhu hunotamba chinzvimbo chakakosha mukusarudza mashandiro ayo munzvimbo dzakananga uye mashandisiro. Kunzwisisa izvi zvivakwa kwakakosha pakushandiswa kunobudirira kweHPMC mune dzakasiyana siyana zvigadzirwa uye maitiro.
