Ungakuthola kanjani okuqukethwe komlotha kwe-hydroxypropyllyll methylcellulose?

Okuqukethwe kwe-Ash kuyinkomba ebalulekile yehydroxypropyl methylcellulose. Amakhasimende amaningi avame ukubuza lapho aqonda khona i-hydroxypropyllllylylyky: Iliphi inani lomlotha? I-Hydroxypropyl methylcellulose enokuqukethwe okuncane komlotha kusho ubumsulwa obuphakeme; I-cellulose enokuqukethwe kwe-Ash okukhulu kusho ukuthi kunokunye ukungcola okukuyo, okuzothinta umphumela wokusebenzisa noma ukukhulisa inani lesengezo. Lapho amakhasimende ekhetha i-hydroxypropyllylylylylyly, imvamisa akhanya ngokuqondile amanye amaselula ngomlilo futhi akushise ukuvivinya okuqukethwe komlotha weselula. Kepha le ndlela yokutholwa ayivumelani kakhulu, ngoba abakhiqizi abaningi bengeza ukusheshisa kokuhlangana ku-cellulose. Ebusweni, i-cellulose inomlotha omncane kakhulu ngemuva kokuvutha, kodwa ekusebenzeni, ukugcinwa kwamanzi kwe-hydroxypropylyllllllllls methylcellulose akukuhle kakhulu.

Ngakho-ke kufanele sikuthole kanjani kahle okuqukethwe kwe-Ash kwe-hydroxypropylllyllose methylcellulose? Indlela yokutholwa efanele ukusebenzisa isithando somlilo sokuthola.

Ibhalansi yokuhlaziywa kwensimbi, i-High Temperature Muffle Fudler Furnic, isithando sikagesi.

Inqubo yokuhlola:

1) Okokuqala, faka i-porcelain engu-30ml ebekwe endaweni yokushisa okushisa kakhulu Out the ecacelwe futhi ukuhambisa ku-desiccator ukuze upholile (20 ~ 30) imizuzu, enesisindo.

2) isisindo 1.0 g yehydroxypropyl methylcelluloseKokulinganisela kokuhlaziywa, faka isampula elinesisindo libe yinto ebekiwe, bese ubeka e-Earcicible equkethe isampula esithandweni sikagesi se-Carbonization, epholile lokushisa kwegumbi, engeza i-sulfuric acid (bese uyibeka esithandweni sikagesi Qedela i-Carbonization. Bese uhambisa esithandweni sokushisa esiphakeme se-muffle, ushise (500 ~ 600) ℃ ngehora eli-1, cisha amazinga okushisa aphezulu we-muffle, lapho izinga lokushisa lomlilo liwela ngaphansi kwama-200 ℃, likhiphe bese lilibeka ku-desiccator Ukupholisa (20 ~ 30) amaminithi, bese kunesisindo esilinganisweni sokuhlaziya.

Ukusalela kokulahla kokubala kubalwa ngokuya ngefomula (3):
