IHydroxypropyl methylcellulosesisixhobo esisetyenziswa ngokubanzi. Ngokukodwa ekusebenziseni i-putty powder. Kukho iipropathi ezininzi zemveliso ezinje: ukuxhathisa ityuwa, umsebenzi ongaphezulu, i-thermal gelation, ukuzinza kwe-PH, ukugcinwa kwamanzi, ukunamathela, njl. Nangona kunjalo, i-hydroxypropyl methylcellulose nayo ixhomekeke kwiingxaki ezithile. Kukho izizathu ezithathu zeengxaki:
1. Ukusetyenziswa kwe-hydroxypropyl methylcellulose
I-2, isixa sezinto ezisisiseko
3. Yindibaniselwano enengqiqo yokuzalisa kwifomula
Ngokomzekelo, imodeli ye-viscosity ye-hydroxypropyl methylcellulose isetyenziswe ngendlela engafanelekanga, inani lezinto ezisisiseko likhulu kakhulu, ukucocwa kwe-filler kuhle kakhulu, njl. imodeli ye-viscosity ye-100,000 yeMveliso, umthamo akufanele ube ngaphantsi kwe-3.5 kg / toni, kunye nomthamo we i-polyvinyl alcohol yomgubo akufanele ibe nkulu kakhulu, ingabi ngaphezu kwe-6%. I-fineness filler ngokuqhelekileyo isebenzisa i-325 mesh yesiqhelo yokuzalisa, kwaye xa idlula i-600 mesh, ukusebenza kolwakhiwo kuya kuchaphazeleka kakubi. Qaphela ukuba le meko ingentla kufuneka isombulule ingxaki yebhetshi embindileyo.
