ʻO ke kumu i hoʻohana nui ʻia ai ka hydroxypropyl methylcellulose

Hoʻohana ʻia ʻo Hydroxypropyl methylcellulose i nā ʻano āpau o ke ola. He aha ke ʻano o ka mea maka?

Mai kahi hiʻohiʻona kino, hydroxypropyl methylcellulose he non-ionic cellulose ether, pauka keʻokeʻo, a ʻaʻohe ona ʻono. I ka ʻoihana kūkulu, hiki ke hoʻohana ʻia ma ke ʻano he mea mālama wai a me ka retarder no ka mortar sima e hana i ka mortar pumpable.

Eia kekahi mau waiwai o ka hydroxypropyl methylcellulose:

1. Me kona kūpaʻa maikaʻi, hiki ke hoʻohana ʻia nā emulsions a me ka wai-soluble resin coatings e like me emulsifiers, stabilizers a me thickeners, etc., i mea e hana ai i ka uhi ʻana i ka pale a me ka hoʻopili, a ʻae i ka waiwai PH paʻa.

2. Loaʻa iā ia ka paʻa wai. ʻO ka hana nui o ka pauka putty hydroxypropyl methylcellulose hiki iaʻu ke mālama i ka wai a pāʻani i ka hana o ka lubrication a me ka hoʻopili. Hoʻomaikaʻi ia i ka pale ʻana a me ka ʻili ponoʻī e pale aku i ka pauka.

3. Loaʻa iā ia ka dispersibility maikaʻi i nā resins synthetic. Ma ke ʻano he mea pale, hiki i ka hydroxypropyl methylcellulose ke hana i kahi hana koʻikoʻi i ka pale ʻana i ka hui ʻana o nā ʻāpana polymer a me ka hoʻomaikaʻi ʻana i ka paʻa o ka dispersion particle resin.

Ma waho aʻe o kēia mau waiwai, hydroxypropyl methylcellulose, a me ka mānoanoa maikaʻi, ka hoʻopili ikaika, ke kūkulu ʻana a me nā ʻano ʻē aʻe, hiki ke ʻike ʻia he maikaʻi loa kāna hana. Ma muli o kēia mau hana, hoʻohana nui ʻia ka hydroxypropyl methylcellulose i nā ʻoihana he nui, e like me ka ʻoihana kūkulu hale, ʻoihana uhi, a me nā mea ʻē aʻe, a he mea nui ka hydroxypropyl methylcellulose.
