Hydroxypropyl methyl seluplose

Hydroxypropyl methylcelculose (hpmc)Ngaba i-polymer eguquguqukayo efumana izicelo kumashishini ahlukeneyo anjengamayeza, amayeza, ukutya, kunye nolwakhiwo. Ngaphandle kwenqanaba layo elibanzi lokusetyenziswa, kukho iingxaki ezininzi ezifanayo ezinxulumene ne-HPMC ukuba abasebenzisi banokudibana.

Ingxaki yokuhlwempuzeka: Ingxaki enye ye-HPMC kukungabinamlili kwawo kumanzi abandayo. Oku kunokukhokelela kubunzima ekuqulunqweni kwezisombululo, ngakumbi xa kufuneka ukonakaliswa ngokukhawuleza. Ukuzoyisa lo mba, ezinye iindlela zibandakanya i-hydration plarimen, usebenzisa amanzi afudumeleyo, okanye amaqhinga e-co-dochents ukonyusa isoba.

Umahluko we-viscosity: UVekyusi weZisombululo ze-HPMC unokuhluka ngenxa yezinto ezinje ngobushushu, inqanaba le-Shear, kunye nePolymer Distination. U-viscofity ongathobekanga unokuchaphazela intsebenzo yokwenziwa, ekhokelela kwimiba enjengoMgangatho wemveliso engekho mgangathweni okanye ukukhutshwa ngamachiza angonelanga kwizicelo zamayeza. Abavelisi kufuneka balawule ngenyameko iimeko zokulungisa ukunciphisa ukuguquguquka kwe-viscofity.

Indalo e-Hygroscopic: I-HPMC inotyekelo lokufumana umswakama kwindalo esingqongileyo, enokuthi ichaphazele iipropathi zayo kwaye ibangele ukuba i-cung okanye iqulunqe kwimigudu yowomileyo. Ukunciphisa le ngxaki, iimeko zokugcina ngokufanelekileyo, ezinje ngemimandla ephantsi yokufuma kunye nokupakisha ubungqina, kubalulekile.

Ukuziphatha okusebenzayo: Kweminye imisebenzi, i-HPMC inokubonakalisa indlela yokuziphatha, ngakumbi malunga nokugxininisa kakhulu okanye phambi kwee-ion ezithile. Ngelixa ukugcwala kunokubakho kwizicelo ezinje ngeenkqubo zokuhambisa iziyobisi, kunokukhokelela kwimiceli mngeni okanye ukufunyanwa okungafunekiyo kwezinye iimveliso. Ukuqonda izinto ekuthathelwa ingqalelo i-gel yejeli kubalulekile ekulawuleni intsebenzo yemveliso.

Imicimbi yokuhambelana: I-HPMC ayinakuhambelana nezithako ezithile okanye ezongeziweyo ezisetyenziswayo ezisetyenziswayo kwifomu. Ukungahambelani kunokubonakala njengokwahlukaniswa kwesigaba, okanye ukutshintsha, okanye utshintsho kwi-viscofity, enokuthi ithole uzinzo lwemveliso kunye nokusebenza kakuhle. Uvavanyo lokuhambelana kufuneka lwenziwe ukubonisa kunye nokulungisa imiba enokubakho ngexesha lokuqulunqwa.

I-Shear Shoring: Izisombululo ze-HPMC zihlala zibonisa indlela yokuziphatha ye-Shear, ezithetha ukuba i-viscofity yabo incipha phantsi koxinzelelo lwe-Shear. Ngelixa le propati inokuba yingenelo kwizicelo ezinjengeendleko kunye neminyango, inokubeka imiceli mngeni ngexesha lokuqhutywa okanye isicelo, ngakumbi kwiinkqubo ezifuna ukubonwa. Uhlobo olufanelekileyo lweRokiology lubalulekile ekusebenzeniyo kokuqulunqwa kwemisebenzi.

Ukonakaliswa kwe-thermal: Amaqondo obushushu aphezulu anokubangela ukonakala kwe-HPMC, okhokelela ekunciphiseni kwi-viscofity, utshintsho kubunzima bemolekyuli, okanye ukwenziwa kweemveliso zokuphelisa. Uzinzo lwe-thermal luqwalaselo olubalulekileyo ngexesha lokugcina kunye nokugcinwa, kwaye abavelisi kufuneka bakwazi ukulawula ngononophelo ukunciphisa ukuncipha nokugcina umgangatho wemveliso.

Ukuthotyelwa komthetho: Kuxhomekeka ekusetyenzisweni ngenjongo kunye nendawo, iimveliso ze-HPMC zinokuba ziphantsi kweemfuno zemigangatho nemigangatho ye-HPMMC yokhuseleko ukhuseleko, ukucoceka, kunye neelebheli. Ukuqinisekisa ukuthotyelwa kwemigaqo efanelekileyo kubalulekile ekwenzeni ukwamkelwa kwintengiso kunye nokuthotyelwa kwezomthetho.

ngelixahydroxypropyl methylcelceluploseInikezela ngezibonelelo ezininzi njenge-polymer ye-polymer, abasebenzisi banokuhlangabezana nemiceli mngeni enxulumene nomoya onxulumene nomoya, i-viscosity, indlela yokuziphatha, indlela yokuziphatha, ukuzinza, nokuzinza komthetho, kunye nokuthotyelwa kwenkohliso, kunye nokuthotyelwa kwenkohliso, nokuzinza komthetho kunye nokuthotyelwa kolawulo. Ukujongana nezi ngxaki ziqhelekileyo kufuna ukuqonda okuchanileyo kweepropathi zePolymer, izinto zokwakha izinto, kunye neemeko zokulungisa, kunye neendlela ezifanelekileyo zokunciphisa zilungiselelwe izicelo ezithile.
