Ke viscosity e nepahetseng ka ho fetisisa ea hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose hangata e sebelisoa ka putty powder e nang le viscosity ea 100,000, ha seretse se na le tlhokahalo e batlang e le holimo, kahoo e lokela ho sebelisoa ka viscosity ea 150,000. Mosebetsi oa bohlokoa ka ho fetisisa oa hydroxypropyl methylcellulose ke ho boloka metsi, ho lateloa ke ho teteaneng. Ka hona, ka phofo ea putty, hafeela ho boloka metsi ho finyelloa, viscosity e tlaase. Ka kakaretso, ha viscosity e kholoanyane, ho boloka metsi ho molemo, empa ha viscosity e feta 100,000, viscosity ha e na phello e fokolang ho boloka metsi.

Ho latela viscosity, hydroxypropyl methylcellulose hangata e arotsoe ka mefuta e latelang:

1. Viscosity e tlaase: 400 viscosity cellulose, haholo-holo e sebelisetsoang seretse sa ho ikemela.
E na le viscosity e tlase le fluidity e ntle. Ka mor'a ho eketsa, e tla laola ho bolokoa ha metsi holim'a metsi, ho tsoa mali ha ho totobetse, ho fokotseha ho nyane, ho phunyeha ho fokotsehile, hape ho ka hanela sedimentation le ho matlafatsa metsi le ho pompa.

2. Viscosity e bohareng le e tlaase: 20,000-50,000 viscosity cellulose, haholo-holo e sebelisoang lihlahisoa tsa gypsum le li-caulking agents.
Viscosity e tlase, ho boloka metsi a mangata, ho sebetsa hantle, ho eketsoa ha metsi a fokolang,

3. Medium viscosity: 75,000-100,000 viscosity cellulose, haholo-holo e sebelisetsoang putty ea ka hare le ka ntle ea lerako.
Viscosity e itekanetseng, ho boloka metsi hantle, kaho e ntle le ho drapability

4. Viscosity e phahameng: 150,000-200,000, haholo-holo e sebelisetsoang polystyrene particle insulation mortar rubber powder, vitrified microbead insulation seretse.
Ka viscosity e phahameng le ho boloka metsi a mangata, seretse ha se bonolo ho theola molora le ho senya, e leng ho ntlafatsang kaho.

Ka kakaretso, ha viscosity e phahame, ho boloka metsi ho molemo, kahoo bareki ba bangata ba tla khetha ho sebelisa selulose e bohareng ba viscosity (75,000-100,000) sebakeng sa cellulose ea viscosity e bohareng (20,000-50,000) ho fokotsa chelete e eketsehileng, ebe joale ho laola litšenyehelo
