1.Ukuhlukaniswa:
I-HPMCingahlukaniswa ngohlobo olusheshayo kanye nohlobo lwe-hot-melt. Imikhiqizo yohlobo olusheshayo ihlakazeka ngokushesha emanzini abandayo bese inyamalala emanzini. Ngalesi sikhathi, uketshezi alunayo i-viscosity, ngoba i-HPMC ihlakazekile kuphela emanzini futhi ayinakho ukuchithwa kwangempela. Ngemva kwemizuzu emi-2, i-viscosity yoketshezi yanda kancane kancane ukuze yakhe i-viscous colloid esobala. Imikhiqizo encibilikayo eshisayo, lapho ihlangana namanzi abandayo, ingahlakazwa ngokushesha emanzini ashisayo futhi inyamalale emanzini ashisayo. Lapho izinga lokushisa lehla lifinyelela ezingeni elithile lokushisa, i-viscosity ibonakala kancane kuze kube yilapho kwakheka i-viscous colloid esobala. Uhlobo lwe-hot-melt lungasetshenziswa kuphela ku-putty powder nodaka. Ku-glue ewuketshezi nopende, i-clumping phenomenon izokwenzeka futhi ayikwazi ukusetshenziswa. Uhlobo olusheshayo lunohlu olubanzi lwezinhlelo zokusebenza. Ingasetshenziswa ku-putty powder nodaka, kanye ne-glue ewuketshezi nopende, ngaphandle kokuphikisana.
2.Indlela yokuhlakaza:
Indlela yokuncibilika kwamanzi ashisayo: Njengoba i-HPMC ingancibiliki emanzini ashisayo, i-HPMC ingahlakazwa ngokufanayo emanzini ashisayo esigabeni sokuqala, bese incibilika ngokushesha ngesikhathi sokupholisa. Izindlela ezimbili ezijwayelekile zichazwa kanje: 1), faka inani elidingekayo esitsheni samanzi ashisayo bese ushisisa kuze kufike ku-70°C. I-hydroxypropyl methylcellulose yengezwa kancane kancane ngokunyakaziswa kancane, ekuqaleni i-HPMC yantanta phezu kwamanzi, bese kancane kancane yakha udaka, olwapholiswa ngokushukumisa. 2), engeza inani elidingekayo le-1/3 noma i-2/3 yamanzi esitsheni, bese uyishisa ibe ngu-70 ° C, ngokwendlela ye-1), hlakaza i-HPMC, ulungise amanzi ashisayo ashisayo; bese ufaka inani elisele lamanzi abandayo emanzini ashisayo Ku-slurry, ingxube yayipholile ngemva kokugqugquzela.
Indlela Yokuxuba Impushana: Xuba i-HPMC powder nenani elikhulu lezinye izinto eziyimpuphu, xuba kahle ne-mixer, bese ufaka amanzi ukuze uncibilike, bese i-HPMC ingancibilika ngalesi sikhathi ngaphandle kokuhlangana ndawonye, ngoba wonke amakhona amancane ane-HPMC encane kuphela Impushana izoncibilika ngokushesha lapho ihlangana namanzi. ——Le ndlela isetshenziswa abakhiqizi be-putty powder kanye nodaka. [I-Hydroxypropyl methylcellulose (HPMC)isetshenziswa njenge-thickener kanye ne-ejenti yokugcina amanzi ku-putty powder mortar]
