Zingaki izinhlobo ze-Hydroxypropyl methylcellulose (HPMC)?

I-Hydroxypropyl methylcellulose (HPMC) ihlukaniswe yaba uhlobo olusheshayo kanye nohlobo lwe-hot-melt.

Ngokuphazima kwesoI-Hydroxypropyl methylcellulose (HPMC)ihlakazeka ngokushesha emanzini abandayo bese inyamalala emanzini. Ngalesi sikhathi, uketshezi alunayo i-viscosity, ngoba i-HPMC ihlakazekile emanzini futhi ayincibiliki ngempela. Cishe imizuzu emi-2, i-viscosity yoketshezi yanda kancane kancane, yakha i-viscous colloid esobala.

I-Hot-melt Hydroxypropyl methylcellulose (HPMC), uma ihlangene emanzini abandayo, ingahlakazeka ngokushesha emanzini ashisayo bese inyamalala emanzini ashisayo. Lapho izinga lokushisa lehlela ezingeni elithile lokushisa (umkhiqizo we-Shijiazhuang Lvyuan Cellulose Co., Ltd. ungama-degree Celsius angama-60), i-viscosity ibonakala kancane kuze kube yilapho kwakhiwe i-viscous colloid esobala.

I-Hot-melt Hydroxypropyl methylcellulose (HPMC) ngokuvamile isetshenziswa ku-putty powder nodaka. Indlela yokuxuba i-powder iyamukelwa: i-HPMC powder ixubene nenani elikhulu lezinye izinto eziyimpushana, ihlanganiswe kahle ne-mixer, bese ihlakazwa ngokungeza amanzi, khona-ke i-HPMC ingaqedwa ngaphandle kokubumbana kwe-clumping, ngoba ikhoneni ngalinye elincane liqukethe kuphela. impushana encane ye-HPMC, ezoncibilika ngokushesha lapho ihlangana namanzi.

I-Instant Hydroxypropyl methylcellulose (HPMC) inohlu olubanzi lwezinhlelo zokusebenza. Ngaphezu kwe-putty powder nodaka, isetshenziswa kakhulu emikhiqizweni yansuku zonke yamakhemikhali njengeglue ewuketshezi, upende, nesihlanzi.
