Tambayoyin da ake yawan yi (FAQs)

Tambaya: Menene N-Methylmorpholine N-Oxide (NMMO)?

A: NMMO wani fili ne na amine oxide da aka yi amfani da shi da farko azaman kaushi don cellulose a cikin tsarin samar da fiber na Lyocell kuma a matsayin co-oxidant a cikin halayen sunadarai na kwayoyin halitta.

Tambaya: Ta yaya NMMO ke aiki a cikin tsarin Lyocell?

A: NMMO yana narkar da ɓangaren litattafan almara kai tsaye (ba tare da rarrabuwa ba) ta hanyar karya haɗin gwiwar hydrogen na intermolecular, samar da dope mai danko. Ana jujjuya wannan maganin a cikin zaruruwa kuma ana sabunta shi a cikin wankan ruwa, tare da dawo da NMMO kuma an sake yin fa'ida.

Tambaya: Ana ba da NMMO azaman mai ƙarfi ko mafita?

A: Ana ba da NMMO a matsayin mai ƙarfi ko azaman maganin ruwa (yawanci 50-60%), dangane da buƙatun abokin ciniki.

Tambaya: Shin NMMO yana da alaƙa da muhalli?

A: iya. Ana ɗaukar NMMO a matsayin koren kaushi saboda ana iya dawo da shi kuma a sake yin fa'ida a farashi mai yawa kuma baya buƙatar haɓakar sinadarai na cellulose.

Tambaya: Ta yaya za a adana NMMO?

A: Ya kamata a adana shi a wuri mai sanyi, bushe, kariya daga danshi da hasken rana kai tsaye, tare da kwantena da aka rufe sosai.

Tambaya: Me yasa zabar NMMO akan sauran sauran kaushi na cellulose?

A: Yana ba da damar rushewar cellulose kai tsaye, yana ba da damar dawo da ƙarfi mai ƙarfi, kuma yana goyan bayan samarwa mai ɗorewa, mara guba na sabbin zaruruwa masu inganci.
