Ko te take i whakamahia nuitia ai te hydroxypropyl methylcellulose

Kei te whakamahia inaianei te Hydroxypropyl methylcellulose ki nga waahi katoa o te ao. He aha te momo rauemi mata?

Mai i te tirohanga tinana, ko te hydroxypropyl methylcellulose he ether cellulose kore-ionic, he paura ma, kaore he reka. I roto i te ahumahi hanga, ka taea te whakamahi hei kaihoko pupuri wai me te retarder mo te moata ciment kia pai ai te pupuhi.

E whai ake nei etahi ahuatanga o te hydroxypropyl methylcellulose:

1. Ki tona pai pūmautanga, emulsions me coatings kapia wai-wairewa e taea te whakamahi rite emulsifiers, stabilizers me thickeners, me ētahi atu, kia rite ki te hanga i te paninga kakahu-ātete me te whakapiri, me te tuku uara PH pūmau.

2. He pupuri wai. Ko te mahi matua o te paura putty hydroxypropyl methylcellulose ka taea e au te pupuri i te wai me te mahi i te mahi whakahinuhinu me te adhesion. Ka whakapai ake i te whakaheke me te kiri-whaiaro hei aukati i te ahua o te paura.

3. He pai te dispersibility i roto i te kapia waihanga. Hei kaihoko tiaki, ka taea e te hydroxypropyl methylcellulose te whai waahi nui ki te aukati i te whakahiatotanga o nga matūriki polymer me te whakapai ake i te pumau o te marara matūriki kapia.

I tua atu i enei taonga, hydroxypropyl methylcellulose, me te pai o te matotoru, te kaha o te whakapiri, te hanga me etahi atu ahuatanga, ka kitea he tino pai tana mahi. Na enei mahi, ka whakamahia te hydroxypropyl methylcellulose i roto i te maha o nga ahumahi, penei i te ahumahi hangahanga, te ahumahi whakakikorua, me etahi atu, he mea nui te hydroxypropyl methylcellulose.
