Eli nqaku lihlola ukuba yintoni i-MHEC, indlela eyenziwa ngayo, iimpawu zayo eziphambili, kunye nesizathu sokuba idlale indima ebaluleke kangaka kwimilo yanamhlanje yedaka kunye nepeyinti.

Ukuqonda i-MHEC

Yintoni i-MHEC?

I-Methyl Hydroxyethyl Cellulose (MHEC) yi-non-ionic cellulose ether ephuma kwi-cellulose yendalo, edla ngokufumaneka kwii-cotton linters ezicociweyo okanye kwi-wood pulp.

Ngenkqubo yokulawula i-etherification, i-cellulose iguqulwa ngokweekhemikhali ngokwazisa:

  • Amaqela eMethyl
  • Amaqela e-Hydroxyethyl

Olu tshintsho luguqula i-cellulose enganyibilikiyo ibe yi-polymer enyibilikayo emanzini eneempawu ezintle zokuqina kunye nokugcina amanzi.

 

I-MHEC ikwintsapho enye efana nale:

Phakathi kwezi ethers ze-cellulose, i-MHEC ithandwa kakhulu kwizicelo zokwakha ngenxa yokugcina kwayo amanzi okuphezulu kunye nokuhambelana kwayo okuhle neenkqubo zesamente kunye ne-gypsum.

Ulwakhiwo lweKhemikhali lwe-MHEC

Umqolo we-cellulose uqulethe iiyunithi ze-anhydroglucose eziphindaphindayo.

Ngexesha lemveliso:

  • Amanye amaqela e-hydroxyl athathelwa indawo ngamaqela e-methyl.
  • Amanye amaqela e-hydroxyl athathelwa indawo ngamaqela e-hydroxyethyl.

Olu tshintsho lubonelela:

  • Ukunyibilika kwamanzi okuphuculweyo
  • Uzinzo oluphuculweyo lobushushu
  • Ukusebenza ngcono kokujiya
  • Ukusebenza kakuhle

Ubungakanani bokutshintshwa bumisela kakhulu ukusebenza kwemveliso kunye nokufaneleka kokusetyenziswa kwayo.

Inkqubo yoMveliso ye-MHEC

Inyathelo 1: Ukulungiswa kweCellulose

I-cellulose ecociweyo eyenziwe ngekotoni okanye ngomthi iyakhethwa ize icocwe.

Inyathelo lesi-2: Ukwenziwa kwe-Alkalization

I-cellulose iphathwa nge-sodium hydroxide ukuze isebenze kwiindawo ezisabelayo.

Inyathelo lesi-3: Ukufakelwa kwe-Ether

I-cellulose esebenzayo iphendula nge:

  • I-Methyl chloride
  • I-ethylene oxide

Oku kungenisa amaqela e-methyl kunye ne-hydroxyethyl kwisakhiwo se-molecular.

Inyathelo lesi-4: Ukungathathi cala

I-alkali engaphezulu ayisebenzi.

Inyathelo lesi-5: Ukuhlamba nokuCoca

Ukungcola kunye neekhemikhali eziseleyo ziyasuswa.

Inyathelo lesi-6: Ukomisa nokusila

Imveliso ecociweyo iyomiswa ize igutywe ibe ngumgubo ocolekileyo ofanelekileyo ukusetyenziswa kwimizi-mveliso.

Iipropati eziphambili ze-MHEC

Ukugcinwa Kwamanzi Okugqwesileyo

Enye yezona mpawu zixabisekileyo ze-MHEC kukukwazi kwayo ukugcina amanzi kwiinkqubo ezisekelwe kwisamente.

Iingenelo ziquka:
