Nhanganyaya: Nei Kuedzwa Kwemhando yeHPMC Kuchikosha
Hydroxypropyl Methylcellulose (HPMC)ndeimwe yezvigadzirwa zve cellulose ether zvinonyanya kukosha zvinoshandiswa mumaindasitiri emazuva ano. Nekuda kwehunhu hwayo hwakasiyana - kusanganisira kukora, kuchengetedza mvura, kuumbwa kwefirimu, kuvandudza kunamira, uye kudzora rheology - HPMC inoshandiswa zvakanyanya mu:
• Dhaka rakasanganiswa nemvura
•Zvinonamira zvemataira
•Masisitimu ekudzivirira eEIFS
•Puti yemadziro
• Gypsum plaster
• Makemikoro anozvienzanisa ega
•Kuputira kwakavakirwa mumvura
• Mishonga
•Zvigadzirwa zvekudya
•Mishonga yekuchengeta munhu
•Mafuta ekuboorera muminda yemafuta
Sezvo zvinodiwa pakushandisa zvichiwedzera kuoma, vagadziri nevashandisi vanoda nzira dzakavimbika dzekuongorora mhando yeHPMC.
Kushanda kweHPMC kunoenderana nezvinhu zvakawanda:
•Kusimba
•Zviri mukati meMethoxy
• Hunhu hweHydroxypropyl
• Dhigirii rekutsiva (DS)
•Kutsiva mamola (MS)
