1. Uhlolojikelele
IHydroxypropyl Methyl Cellulose (HPMC) i-non-ionic cellulose ether eyenziwe ngezinto ze-polymer zemvelo - i-cellulose ngochungechunge lwezinqubo zamakhemikhali.IHydroxypropyl methylcellulose (HPMC) iyimpushana ezenzela umbala engenaphunga, enganambitheki, engenabuthi, engancibilika emanzini abandayo ukuze yakhe isixazululo se-viscous esisobala, esinomsebenzi wokuqina, ukuhlanganisa, ukuhlakaza, ukuhlanganisa, ukwenza ifilimu, kanye nokumisa okwesikhashana, i-adsorption, i-gelation, umsebenzi ongaphezulu, ukugcinwa komswakama kanye nezakhiwo ze-colloid ezivikelayo.
IHydroxypropyl methylcellulose (HPMC) ingasetshenziswa ezintweni zokwakha, okokuhlanganisa, izinhlaka zokwenziwa, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo nezimboni zikagwayi.
2, Ukucaciswa komkhiqizo kanye nezigaba Imikhiqizo ihlukaniswe yaba uhlobo oluncibilikayo lwamanzi abandayo S kanye nohlobo olujwayelekile

3,imvelo yomkhiqizo
Izakhiwo: Lo mkhiqizo uyimpushana emhlophe noma emhlophe, ayinaphunga, ayinambitheki futhinon-toxic.
Ukuncibilika kwamanzi kanye nekhono lokujiya: Lo mkhiqizo ungancibilika emanzini abandayo ukuze wakhe isisombululo se-viscous esisobala.
Ukuncibilika kuzinyibilikisi zemvelo: Ngenxa yokuthi iqukethe inani elithile lamaqembu e-hydrophobic methoxyl, lo mkhiqizo ungancibilika kwezinye izinyibilikisi zemvelo, futhi ungancibilika kuzincibilikisi ezixutshwe namanzi nezinto eziphilayo.
Ukumelana nosawoti: Njengoba lo mkhiqizo uyi-polymer engeyona i-ionic, uzinzile kuzixazululo ezinamanzi zosawoti wensimbi noma ama-electrolyte aphilayo.
Umsebenzi ongaphezulu: Isixazululo esinamanzi salo mkhiqizo sinomsebenzi ongaphezulu, futhi sinemisebenzi nezakhiwo ezifana ne-emulsification, i-colloid evikelayo nokuzinza okuhlobene.
I-Thermal Gelation: Uma isixazululo esinamanzi salo mkhiqizo sishiswa ekushiseni okuthile, siba yi-opaque size senze (i-poly) isimo se-flocculation, ukuze isisombululo silahlekelwe yi-viscosity yayo.Kodwa ngemva kokupholisa, izophenduka ibe yisimo sokuqala sesixazululo futhi.Izinga lokushisa lapho i-gelation livela khona lincike kuhlobo lomkhiqizo, ukugxila kwesisombululo kanye nezinga lokushisa.
Ukuzinza kwe-PH: I-viscosity yesisombululo esinamanzi salo mkhiqizo izinzile phakathi kwebanga elingu-PH3.0-11.0.
Umphumela wokugcina amanzi: Njengoba lo mkhiqizo uyi-hydrophilic, ungangezwa kudaka, i-gypsum, upende, njll. ukuze ugcine umphumela wokugcina amanzi emkhiqizweni.
Ukugcinwa komumo: Uma kuqhathaniswa namanye ama-polymers ancibilika emanzini, isixazululo samanzi salo mkhiqizo sinezici ezikhethekile ze-viscoelastic.Ukwengezwa kwayo kunamandla okugcina ukwakheka kwemikhiqizo ye-ceramic extruded ingashintshiwe.
I-Lubricity: Ukwengeza lo mkhiqizo kunganciphisa i-coefficient ye-friction futhi kuthuthukise ukuthambisa kwemikhiqizo yobumba ekhishwe kanye nemikhiqizo kasimende.
Izakhiwo zokwakha ifilimu: Lo mkhiqizo ungakha ifilimu eguquguqukayo, esobala enezici ezinhle kakhulu zemishini, futhi unowoyela omuhle ukumelana namafutha.
4.Izakhiwo zomzimba namakhemikhali
Usayizi wezinhlayiya: Izinga lokuphasa nge-mesh eyi-100 likhulu kuno-98.5%, izinga lokuphasa le-80 mesh li-100%
Ukushisa kwe-Carbonization: 280 ~ 300 ℃
Ukuminyana okubonakalayo: 0.25~0.70/cm amandla adonsela phansi athile 1.26~1.31
Izinga lokushisa lokushintsha umbala: 190 ~ 200 ℃
Ukushuba kobuso: Isixazululo esinamanzi esingu-2% singama-42 ~ 56dyn/cm
Ukunyibilika: Incibilika emanzini nakwezinye izincibilikisi, isixazululo esinamanzi sinomsebenzi ongaphezulu.High obala.Ukusebenza okuzinzile, izinguquko ze-solubility nge-viscosity, i-viscosity ephansi, i-solubility enkulu.
I-HPMC iphinde ibe nezici zekhono lokuqina, ukumelana nosawoti, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, impahla enhle kakhulu yokwenza ifilimu, kanye nohlu olubanzi lokumelana nama-enzyme, ukuhlakazeka nokuhlangana.
5, inhloso eyinhloko
I-HPMC yebanga lezimboni isetshenziswa kakhulu njenge-dispersant ekukhiqizeni i-polyvinyl chloride, futhi iyi-ejenti eyisizayo eyinhloko yokulungiselela i-PVC ngokumiswa kwe-polymerization.Ngaphezu kwalokho, ingasetshenziswa njenge-thickener, stabilizer, emulsifier, excipient, kanye ne-ejenti yokugcina amanzi ekukhiqizeni amanye amakhemikhali e-petrochemicals, okokugqoka, izinto zokwakha, izinto zokususa upende, amakhemikhali ezolimo, oyinki, ukuphrinta kwendwangu nokudaya, izitsha zobumba, iphepha. , izimonyo, njll., i-ejenti yokwakha ifilimu, njll. Ukusetshenziswa kuma-resin okwenziwa kungenza imikhiqizo etholakalayo ibe nezici zezinhlayiya ezivamile nezixekethile, amandla adonsela phansi afanele kanye nokusebenza okuhle kakhulu kokucubungula, ngaleyo ndlela ngokuyisisekelo esikhundleni se-gelatin ne-polyvinyl utshwala njengama-dispersants.
Izindlela eziyisithupha zokuqeda:
(1).Thatha inani elidingekayo lamanzi ashisayo, ulifake esitsheni bese usishisa libe ngaphezu kuka-80°C, bese wengeza kancane kancane lo mkhiqizo ngaphansi kokunyakaziswa kancane.I-cellulose intanta phezu kwamanzi ekuqaleni, kodwa kancane kancane ihlakazeka ukuze yenze udaka olufanayo.Isixazululo sipholile ngenkathi sinyakaza.
(2).Ngaphandle kwalokho, shisa i-1/3 noma i-2/3 yamanzi ashisayo ibe ngaphezu kuka-85 ° C, engeza i-cellulose ukuze uthole i-slurry yamanzi ashisayo, bese ufaka inani elisele lamanzi abandayo, qhubeka ugoqa, futhi upholise ingxube ewumphumela.
(3).Imeshi ye-cellulose ilungile uma kuqhathaniswa, futhi ikhona njengezinhlayiya ezincane kumpushana ogoqiwe ngokulinganayo, futhi incibilika ngokushesha lapho ihlangana namanzi ukuze yakhe i-viscosity edingekayo.
(4).Kancane kancane futhi ngokulinganayo wengeze i-cellulose ekamelweni lokushisa, uvuselela ngokuqhubekayo kuze kube yilapho kwakhiwa isisombululo esibonakalayo.
