Iyo indasitiri giredhi hydroxypropyl methylcellulose inoshandiswa kugadzira dhaka (pano inoreva pure cellulose, kusasanganisa zvigadzirwa zvakagadziridzwa) inosiyaniswa neviscosity, uye anotevera mamakisi anowanzo shandiswa (iyo unit is viscosity):
Low viscosity: 400
Inonyanya kushandiswa kune self-leveling dhaka;iyo viscosity yakaderera, kunyangwe kuchengetwa kwemvura kwakashata, asi pfuma yekuenzanisa yakanaka, uye dhaka density yakakwirira.
Pakati uye yakaderera viscosity: 20000-40000
Inonyanya kushandiswa kunamatira mataira, caulking agents, anti-cracking mortars, thermal insulation bonding mortars, nezvimwewo;kuvakwa kwakanaka, kushoma kwemvura, yakakwira dhaka density.
Medium viscosity: 75000-100000
Inonyanya kushandiswa putty;kuchengetedza mvura zvakanaka.
High viscosity: 150000-200000
Inonyanya kushandiswa polystyrene particle thermal insulation mortar rubber powder uye vitrified microbead thermal insulation mortar;iyo viscosity yakakwirira, dhaka haisi nyore kudonha, uye kuvaka kunovandudzwa.
Mumashandisirwo anoshanda, zvinofanirwa kucherechedzwa kuti munzvimbo dzine tembiricha yakakura misiyano pakati pezhizha nechando, zvinokurudzirwa kushandisa yakaderera viscosity munguva yechando, iyo inobatsira pakuvaka.Kana zvisina kudaro, kana kutonhora kwakaderera, viscosity ye cellulose inowedzera, uye kunzwa kwemaoko kuchave kunorema pakukwesha.
Kazhinji kutaura, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura.Tichifunga nezvemutengo, mafekitori mazhinji akaoma ehupfu anotsiva epakati uye akaderera viscosity cellulose (20000-40000) nepakati-viscosity cellulose (75000-100000) kuderedza kuwanda kwekuwedzera.Zvigadzirwa zvedhaka zvinofanirwa kusarudzwa kubva kune vanogadzira nguva dzose uye kuzivikanwa.
Hukama pakati pe viscosity uye tembiricha yeHPMC:
Iyo viscosity yeHPMC inopindirana nekushisa, kureva kuti, viscosity inowedzera sezvo tembiricha inoderera.Iyo viscosity yechigadzirwa chatinowanzo taura nezvayo inoreva bvunzo mhedzisiro yayo 2% aqueous solution patembiricha ye20 degrees Celsius.
