Cara Pembuangan Hydroxypropylus Methylcellulose

Methylcellulose hydroxypropylose, uga dikenal minangka HPMC, minangka Ether Cellulose Non-ionik sing dipikolehi dening pirang-pirang pangolahan kimia karo bahan polimer alami sing diisi katun minangka bahan mentah. Iku bubuk putih utawa rada kuning, larut banyu kanthi gampang. Ayo ngobrol babagan metode pembubaran saka metilcellulosa hydroxypropyl.

Piranti / Bahan
Hydroxypropylmethylcellulose
Banyu
Cara / Langkah
Kaping pisanan, methylcellulosa hydroxypropellumis utamane digunakake minangka aditif kanggo bubuk, mortir lan lem. Yen ditambahake mortir, bisa digunakake minangka agen pemaca lan retard kanggo nambah kumpab; Nalika ditambahake ing bubuk lan lem, bisa digunakake minangka binder. Kanggo nambah paningkatan lan ndawakake wektu operasi, ayo njupuk selulosa Qingquan minangka conto kanggo nerangake cara pembubaran hydroxypropylulule hydroxyplellulule.

Methylcellulosis hydroxypropylus biasa diudhek lan disebar karo banyu panas, banjur larut kanthi nambah banyu adhem, aduk lan adhem;

Khusus: Njupuk 1 / 5-1 / 3 jumlah banyu panas sing dibutuhake, aduk nggawe produk sing ditambahake, banjur tambah bagean sing adhem, utawa banyu es sing bisa dadi banyu sing cocog, lan aduk banyu sing cocog (10 ° C) supaya bisa larut.

Cara Weting Solvent Organic:

Disperse hydroxypropyl methylcellulose in an organic solvent or wet it with an organic solvent, and then add it to cold water or add cold water, it can be well dissolved, and the organic solvent can be ethanol, ethylene glycol, etc.

4
Yen ana aglomerasi lan bungkus sajrone dissolution, amarga aduk ora cukup utawa model biasa ditambahake langsung menyang banyu adhem. Ing wektu iki, kudu diudhek kanthi cepet.

5
Yen gelembung digawe sajrone pembubaran, bisa ditinggalake sajrone 2-12 jam (wektu tartamtu ditemtokake dening konsistensi solusi) utawa dicopot kanthi cepet, utawa nambah jumlah agen defoaming sing cocog.

Pungkasan
Cegahan
Methylcellulosa hydroxypropylose dipérang dadi jinis sing alon-alon lan jinis bubar. Cepet-bubar metilcellulosa hydroxypropyL bisa langsung larut ing banyu adhem.
