I-viscosity ephezulu 200000 HPMC

IHydroxypropyl Methylcellulose (HPMC)yi-non-ionic cellulose ether esetyenziswa kakhulu kulwakhiwo, amayeza, ukutya, iikhemikhali zemihla ngemihla kunye nezinye izimboni. Ngokwe-viscosity yayo, i-HPMC inokwahlulwahlulwa ibe yi-viscosity ephantsi, i-viscosity ephakathi kunye ne-viscosity ephezulu. Phakathi kwazo, i-HPMC ene-viscosity engama-200000 mPa·s ikwi-viscosity ephezulu, ineempawu ezigqwesileyo zokuqina, ukwenza ifilimu kunye nokugcina amanzi, kwaye inexabiso elikhethekileyo lokusetyenziswa kwiinkalo ezininzi.

1. Iimpawu ezisisiseko

I-HPMC ene-viscosity ephezulu (200000 mPa·s) yenziwe nge-polymer cellulose yendalo kwaye iguqulwa yi-etherification. Inkangeleko yayo idla ngokuba ngumgubo omhlophe okanye omhlophe othambileyo kwaye kulula ukuyisasaza. Olu hlobo lwe-HPMC lunokusasazwa ngokukhawuleza emanzini abandayo ukuze lwenze isisombululo esicacileyo okanye esikhanyayo. Ixabiso layo le-viscosity libhekisa kwi-viscosity eguquguqukayo elinganiswa kwisisombululo samanzi se-2% kwi-20°C, ifikelela kwi-200000 mPa·s, ebonisa ukuhambelana okuphezulu kakhulu kunye neempawu ze-rheological.

2. Ukusebenza okuphambili

Ukugcinwa kwamanzi okugqwesileyo

I-HPMC ene-viscosity ephezulu inomthamo omkhulu wokufunxa amanzi kunye nokugcina amanzi, ingakumbi kwizixhobo zokwakha, inokuthintela ngempumelelo ukuba amanzi angatshi ngokukhawuleza, kwaye ithintele ukuqhekeka kunye nokulahleka kwamandla okubangelwa kukulahleka kwamanzi.

Ukutyeba kunye nokuthambisa

I-HPMC enomgangatho we-viscosity we-200000 inefuthe elibonakalayo lokutyeba, kwaye nokuba ubungakanani bokongeza buphantsi, inokunyusa kakhulu i-viscosity yesisombululo okanye inkqubo. Kwangaxeshanye, ineempawu ezilungileyo zokuthambisa kunye nokwakha, okwenza ipeyinti, i-putty kunye ne-mortar zibe lula kwaye kube lula ukuyisebenzisa ngexesha lenkqubo yokwakha.

Ipropati entle yokwenza ifilimu

Olu hlobo lwe-HPMC lunokwenza ifilimu eqinileyo, eguquguqukayo necacileyo emva kokomiswa, nto leyo enceda ekuphuculeni ukumelana nokuguguleka kunye nokunamathela kwengubo.

Uzinzo oluqinileyo lweekhemikhali

I-HPMC yi-polymer engeyiyo i-ionic, ezinzileyo kwii-asidi kunye nee-alkali kwaye akulula ukuyiphendula nezinye izinto zeekhemikhali, nto leyo eyenza ukuba ihambelane kakuhle kwiifomyula ezintsonkothileyo.

3. Intsimi yesicelo

Ishishini lokwakha

I-HPMC ene-viscosity ephezulu isetyenziswa kakhulu kwizixhobo zokwakha ezifana nodaka olomileyo, i-tile adhesive, i-thermal insulation mortar, i-putty powder, njl. Imisebenzi yayo yokutyeba kunye nokugcina amanzi inokuphucula kakhulu ukusebenza kolwakhiwo, iphucule ukunamathela kunye neempawu zokungatyibiliki.

Ishishini lamayeza

Njengesixhobo sokukhulula amayeza esilawulwayo kunye nezinto zegobolondo le-capsule, i-HPMC ene-viscosity ephezulu ingasetyenziswa njengeyona nto iphambili kumalungiselelo okukhululwa okuqhubekayo ukwandisa ixesha lokukhululwa kwamayeza kunye nokuphucula ukufumaneka kwawo.

Ishishini lokutya

Isetyenziswa njenge-emulsifier, i-stabilizer, i-suspensing agent kunye ne-thickener ekutyeni, njengakwizinto zokutya ezinamafutha aphantsi kunye neemveliso ezibhakiweyo ukuphucula ubume kunye nencasa.

Intsimi yemichiza yemihla ngemihla

I-HPMC isetyenziswa njengesithambisi kunye nesiqinisi kwishampu, isicoci sobuso, kunye neloshini ukuphucula inkangeleko kunye nokuvakala kwemveliso.

4. Ukusetyenziswa kunye neendlela zokuzikhusela

Xa usebenzisa i-HPMC enoburhabaxa obuphezulu, kufuneka yongezwe kancinci emanzini kubushushu begumbi kwaye isasazwe ngelixa ixutywa ukuze kuthintelwe ukuhlangana. Emva kokuba inkqubo yokusasazwa yenziwe kwinqanaba lokuqala, kufuneka ishiywe imele ukuze kubekho ukufuma okupheleleyo ukuze ekugqibeleni yenze isisombululo se-colloidal esiqinileyo nesicacileyo. I-HPMC akufuneki ixutywe nee-asidi ezinamandla kunye ne-alkalis ukuthintela ukuba isakhiwo sayo se-molecular singatshatyalaliswa. Ukongeza, indawo yokugcina kufuneka iphephe ukufuma kunye nobushushu obuphezulu ukuthintela imveliso ekuhlanganeni ngenxa yokufuma kunye nokuchaphazela ukusebenza.

I-viscosity ephezulu 200000 HPMCiye yaba yinto efunekayo kakhulu kumashishini amaninzi ngenxa yokusebenza kwayo okugqwesileyo kunye nokuguquguquka kwiindawo ezininzi. Ngokuphucuka kweteknoloji kunye nokwanda kwemfuno yemarike, umda wokusetyenziswa kwayo uya kwandiswa ngakumbi. Ukuqonda iimpawu zayo zokusebenza kunye neendlela ezifanelekileyo zokusetyenziswa kuya kuphucula ukusebenza kwayo kwaye kuphucule kakhulu umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso.
