HPMC (HydroxyPropyl methylcellose) inzvimbo inowanzoshandiswa polymer yakaenzana, inoshandiswa zvakanyanya mumushonga, chikafu, zvikafu, zvokuvakwa uye maindasitiri ekuvandudza. Kuita kwayo kunokanganiswa nezvinhu zvakawanda, pakati pei tembiricha ine yakanyanya kukosha pane viscosity yeHPMC solution.
1. Basic hunhu hweHPMC
HPMC ndeye polymer yakawanikwa yakawanikwa nemakemikari kugadziridzwa kwemusango chirimwa cellulose. Iyo ine yakanaka mvura solubility, firimu-inoumba zvivakwa, kururamisa uye kugadzikana. Nekuti chimiro chayo chemakemikari chine hydrophic mapoka akadai se hydroxyl uye methyl mapoka, HPMC inogona kuumba yakakwirira viscossity mhinduro mumvura. Yayo viscosity ine hukama zvakanyanya nezvinhu zvakadai sekusangana, suremu, tembiricha, uye ph kukosha kwemhinduro.
2. Mhedzisiro ye tembiricha pane viscosity yeHPMC Solution
Kuwedzera tembiricha kunotungamira kune kuderera kweViscosity
Iyo viscosity yeHPMC Solution inoderedza nekuwedzera kupisa, iyo yakafanana nezvivakwa zvemari yakawanda yekupenya. Kana tembiricha ichisimuka, iyo yekufambisa yemamolekora yemvura iri pakati pemamolekita (seyakaitwa neHydrogen molecular Car Kunyanya, kuwedzera kwekushisa zvishoma nezvishoma kunoparadza kuyambuka muviri uye hydrogen bond network pakati peiyo hpmc ngetani, ichibvumira maketani ekufambisa zvakasununguka, zvichikonzera kuisirwa rheology uye kuderedza viscosity.
Mhedzisiro yekupisa pane molecular kufamba
Iyo viscosity yeHPMC mhinduro haina kungoenderana neyekunyoreswa nehuremu uye kusvinura, asi zvakare zvine chekuita nekufamba kwemaketani emanyorerwo. Kuwedzera kwe tembiricha kunowedzera iyo inofamba-famba yemamolekyudhi yemvura mumhinduro, uye chiitiko cheHPMC molecular ngetani dzinowedzerawo. Sezvo tembiricha inowedzera, kuchinjika kweiyo hpmc makein kunowedzera, uye mukana wekukanganiswa kana kuwedzera kwekuwedzera kana kuwedzera kunowedzera, izvo zvinochinja rakatsauka kwemhinduro, kuratidzwa sekuderera kwemisangano.
Kuongororwa kwetsika kwekushawa kwemuchina
Hukama pakati pehukama uye tembiricha yeHPMC mhinduro inogona kuwanzotsanangurwa neiyo Arrishenius equation. Iyo equation inoratidza kuti pane imwe hukama hwechokwadi pakati peiyo viscosity yemhinduro uye tembiricha. Zvakananga, iyo viscosity (η) yeiyo mhinduro inogona kutaurwa se:
η = i0 exp (rTEA)
Pakati pavo. Pakupisa kwakanyanya, simba rekutonga rine hukuru hukuru, zvichikonzera visikopa yemhinduro yekudonhedza zvakapinza nekuwedzera tembiricha.
Kugadzikana kweHPMC Solution
Kunyangwe iyo viscosity yeHPMC inoderera nekuwedzera tembiricha, HPMC Soluolise ine yakanaka yekukasira kugadzikana mukati meimwe tembiricha yekupisa. ATHRARA-yakakwira tembiricha, marefu emaketani eHPMC inogona kushatisa, zvichikonzera kuderera kwehuremu hwayo hwemanyorerwe, izvo zvinokonzera kudonha kwakapinza muViscosity. Naizvozvo, mune zvinoshanda zvinoshandiswa, HPMC mhinduro dzinofanira kudzivirirwa kubva mukufumurwa kune yakanyanya tembiricha nzvimbo dzinodarika yavo yekudzikama yekugadzikana.
3. Iyo inoshanda yekushandisa mhedzisiro yekushisa pane viscosity yeHPMC mhinduro
Indasitiri yeMishonga
Muindasitiri yechechi, HPMC inowanzoshandiswa seyekuburitswa-yakaburitswa mumiriri wezvinodhaka, zvinyorwa zvemakapu eCAPULULUL, uye kugadzirira kumwe gadziriro dzakasimba. Mhedzisiro yekushisa pane yayo viscosity inoenderana zvakananga kune iyo mhando uye maitiro ekugadzira ekugadzirira. Kunyanya kukwira tembiricha kuchaguma nekudzikira kwemhinduro yekugadzirisa
Indasitiri yechikafu
Muindasitiri yechikafu, HPMC inoshandiswa zvakanyanya sedhimoni uye emulsifier. Munguva yekugadziriswa kwechikafu, tembiricha yekudziya inogona kukanganisa kuwirirana kweHPMC solution, nekukasira kuravira uye kuumbwa kwechigadzirwa. Naizvozvo, mashura maitiro eViscosity eHPMC Solution pamisiyano yakasiyana inobatsira kudzora zviri nani kudzora maitiro ekugadzirisa ekugadzirisa uye kuve nechokwadi chekugadzikana uye kuravira kwechigadzirwa chekupedzisira.
Kuvaka uye Kuunganidza Indasitiri
Muzvivakwa zvekuvaka uye huku, chikamu chikuru cheHPMC chakafanana nehana uye mvura yeretainer. Sezvo tembiricha shanduko, iyo viscosity shanduko yeHPMC ichakanganisa iyo fluidity, kuderedza nekuita kwekuvaka kwekuita kongiri kana machira. Naizvozvo, mune zvinoshanda zvinoshandiswa, zvinodikanwa kuti ugadzirise huwandu hweHPMC maererano neye ambient tembiricha kuti ive nechokwadi chekufambira mberi kwekuvaka.
Cosmetic indasitiri
Mune cosmetics, hpmc inowanzoshandiswa mukuumbwa kwezvigadzirwa senge matera uye emulsions. Mhedzisiro yekushisa pane viscosity yeHPMC inogona kukanganisa kupararira, kugadzikana uye kutaridzika kwechigadzirwa chechigadzirwa. Kumhepo dzakasiyana siyana, kushandurwa kwemazwi kwemazwi kunogona kukanganisa ruzivo rwemutengi, saka chaiyo tembiricha yekudzora manejimendi inodiwa panguva yekugadzira maitiro.
Mhedzisiro yekushisa kweHPMC mhinduro yeHPMC yemuviri uye yemakemikari maitiro inosanganisira zvinhu zvakadai sekuchinja kwemaketani nemanyorerwo uye shanduko mumasangano ekudyidzana. Kazhinji, kuwedzera tembiricha kuchatungamira kuderera kweiyo visikopo yeHPMC solution, asi mune zvinoshanda zvinoshandiswa, zvakadai sekudziya renji, soupururudza, uye uremu hwe hpmc. Nekudzidza zvakadzika hukama pakati pevisikopo uye tembiricha yeHPMC Solution, tinogona kupa hwaro hwesainzi hwekushandisa mashandiro akasiyana-siyana, tambanudzira maitiro ekugadzira, uye kugadzirisa zvigadzirwa zvechigadzirwa.
