Hydroxethyl Cellulose (Hec) iri polymer yakashandiswa zvakanyanya mumuindasitiri akasiyana siyana nekuda kwezvinhu zvakasarudzika zvakadai sekusarudzika kwemvura, kugona kwemvura, uye kugona. Kunzwisisa kugadzikana kwayo pasi peakasiyana PH mamiriro akakosha pakushandisa kwayo inoshanda.
Hydroxethyl Cellulose (Hec) iri itstivative yemheremalose, chisikwa chinoitika polymer chakawanikwa mumadziro emusero. HEC yakawana kukosha kwakanyanya mumaindasitiri senge mishonga, cosmetics, chikafu, uye kusanganisa solubility yemvura, kugona kwemvura, uye kugona kwemafirimu, uye biocomputer. Nekudaro, kusimba kwehwanda pasi peakasiyana PP mamiriro akakosha pakushandisa kwayo kwakabudirira mukugadziriswa kwakasiyana siyana.
Kugadzikana kwehwanda kunogona kuiswa nezvinhu zvakati wandei, neP kuva imwe yeiyo yakakosha paramita. ph inobata iyo ionization mamiriro emapoka anoshanda aripo muHec, nokudaro achigadzirisa iyo solubility, viscosity, uye zvimwe zvinhu. Kunzwisisa maitiro ehec munzvimbo dzakasiyana PP nharaunda dzakakosha kune vagadziri vezvimiro kuti vagadzirise mashandiro azvo mune dzakasiyana siyana.
1.comemical chimiro che hydroxytHyl cellulose:
HEC yakanyorwa kuburikidza nekuita kwemasero neEtralose oxide, zvichikonzera kuSumo yeHydroxyTH mapoka muCellulose Backbone. Dhigirii rekutsiva Iyo makemikari chimiro chehec inopa hunhu hwakasarudzika hunoita kuti zviite zvakakodzera kune dzakasiyana siyana maindasitiri ekushandisa.
Mapoka epamusoro anoshanda muHec ari hydroxyl (-OOOH) uye ether (-O-) mapoka, ayo anoita basa rakakosha mukudyidzana kwayo nemvura nemamwe mamorekuru. Kuvapo kwehydroxyTHESTL vanowedzera iyo inowedzera hydrophilipity yemasero, inotungamira kuvandudzika solubility yemvura ichienzaniswa neyenzi cellive. Iyo ether zvibodzwa zvinopa kugadzikana kune her h hec mamorekuru, kudzivirira kusvibiswa kwavo pasi pezvakajairwa.
2.Intereractrions naPH:
Iko kusimba kwehisheni mune dzakasiyana PP nharaunda inokurudzirwa neIONZES yemapoka ayo anoshanda. Mumamiriro eAlicIC (PH <7), mapoka e hydroxyl aripo muHec anogona kuzoratidzira progratation, anotungamira kuderera mukugadzirisa newubility uye viscosity. Kukurukurirana, muAlkaline Mamiriro (PH> 7), Displothonation yeHydroxyl Mapoka anogona kuitika, achikanganisa zvivakwa zvePolymer.
PHAKASHURE PH Ichi chiitiko chinonyanya kududzwa madhigirii ekutsiva, uko huwandu hwakakura hwemapoka ehydroxyl aripo kuti azivise. Nekuda kweizvozvo, iyo viscosity yemhinduro dzehec inogona kuderedza zvakanyanya mune acidic nharaunda, inokanganisa mashandiro aro seyekuita mumiriri.
Kune rimwe divi, muAlkaline Mamiriro ezvinhu, kudzikisira kwemapoka eHydroxyl kunogona kuwedzera iyo solubility yehyoko nekuda kwekuumbwa kweiyo alkoxiz ions. Nekudaro, zvakawandisa alkalinity zvinogona kutungamira mukushatiswa kwe polymer kuburikidza neye base-carlyzed hydrolysis yekubatana kwe ether yekubatana, zvichikonzera kuderera kweViscosity uye zvimwe zvivakwa. Naizvozvo, kuchengetedza iyo pH mukati meiyo yakakodzera renji yakakosha kuve nechokwadi chekugadzikana kwehwanda muAlkaline mafomu.
3.Practical Zvinoreva:
Kugadzikana kwehwanda mune dzakasiyana-siyana pP nharaunda ine zvakakosha zvinoshanda zvinoshandiswa pakushandisa kwayo mumaindasitiri akasiyana. Muindasitiri yechechi yechechi, hec inowanzo shandurwa seyekuita mumiririri mukurongedza kwemuromo sekumiswa, emulsions, uye geri. Iyo pH yeaya mafambiro anofanira kunyatso kudzorwa kuti ichengetedze viscosity yaunoda uye kugadzikana kwehwanda.
Saizvozvo, mune yeCosmetic indasitiri, hec inoshandiswa mune zvigadzirwa zvakaita seShampoos, uye mafuta ekurara nekukora uye anofungidzira zvivakwa. Iyo pH yezvimiro izvi zvinogona kusiyana zvakanyanya zvichienderana nezvakaitika zvigadzirwa zvechigadzirwa uye kuwirirana kwehwanda nezvimwe zvinoshandiswa. Vagadziri vanofanira kufunga nezve kukanganiswa kwePH pakugadzikana uye kuita kwehyoko kuti vave nechokwadi chekubudirira kwechigadzirwa uye kugutsikana kwevatengi.
Muindasitiri yechikafu, hec inoshandiswa seyakaoma uye inosimbisa mumiririri mune zvakashata zvigadzirwa, kusanganisira masaga, zvipfeko, uye zveshuwa. Iyo pH yekudya kwekudya inogona kubva kune acidic kuenda kuAlkaline, zvichienderana nezvinonongedzerwa uye mamiriro ekugadzirisa. Kunzwisisa maitiro ehec munzvimbo dzakasiyana-dzakasiyana kuti uzadzise chimiro chaunoda, muromo, uye kugadzikana mune zvigadzirwa zvekudya.
Mune indasitiri yekuvaka, hec inoshandirwa mukushandisa kwakadai seyamentiticious monganda, grouts, uye kuomerera pakuchengeta kwayo kwemvura uye rheological kudzora zvinhu. Iyo pH yezvimiro izvi inogona kusiyana zvichienderana nezvinhu zvakadai sekuporesa mamiriro uye kuvapo kwekuwedzera. Optimizing iyo PH kugadzikana kwehisheni yakakosha nekuda kwekuita basa uye kusimba kwezvinhu zvekuvaka.
Kugadzikana kwehydroxyethyl cellulose (Hek) munzvimbo dzakasiyana siyana Kunzwisisa maitiro ehec pasi pehurongwa hwakasiyana PP mamiriro akakosha kune maFlogulators kuti agadzirise mashandiro azvo mune dzakasiyana siyana. Kuwedzera kutsvagira kunodiwa kuti uise pasi pehunhu hwekutonga kusimba kwehwanda uye nekugadzira mazano ekuwedzera mashandiro azvo pasi penzvimbo ph mamiriro akapokana.
