HGL/HGW fa'asologa tasi-laasaga tu'usa'o ma faalava pamu kemikolo

Fa'atatauga

HGL ma HGW fa'asologa o pamu vaila'aue mafai ona faʻaaogaina i se tulaga faʻapitoa i alamanuia vailaʻau, felauaiga suauʻu, meaʻai, meainu, vailaʻau, togafitiga vai, puipuiga o le siosiomaga ma nisi acids, alkali, masima ma isi talosaga e tusa ai ma tulaga faʻaoga patino a le tagata faʻaoga. O se ala e pala, e leai ni mea ninii malo po o ni vaega laiti, ma e iai lona viscosity e pei o le vai. E le fautuaina mo le fa'aogaina i tulaga o'ona, mu, pa, po'o tulaga e sili ona pala.

(1) Nitric acid ma faʻaoga i le gaosiga o meaʻai nitric

I le faagasologa o le gaosia o le nitric acid e ala i le ammonia oxidation, o le dilute nitric acid (50-60%) o loʻo faʻatupuina i totonu o le uʻamea faʻafefe uamea e tafe mai le pito i lalo o le olo i totonu o le tane e teu ai uamea, ma o loʻo aveina atu i le isi gaioiga. fa'atasi ai ma se pamu uamea. Fa'alogo lelei i le vevela ma le fa'aulufale i'i.

(2) Talosaga i phosphoric acid ma phosphoric acid alamanuia

Mo acid mama, Cr13 u'amea u'amea na o le tetee i aerated dilute acid, ma chromium-nickel (Cr19Ni10) austenitic u'amea u'amea na o le tetee i aerated dilute acid. O mea sili ona lelei o le phosphoric acid-resistant o le chromium-nickel-molybdenum (ZG07Cr19Ni11Mo2) uʻamea uʻamea, ma isi.

Ae ui i lea, mo le gaosiga o le gaosiga o le phosphoric acid, o le filifilia o mea o le pamu e sili atu ona faigata ona o faʻafitauli faʻaleagaina e mafua mai i le i ai o mea leaga i le phosphoric acid, ma e tatau ona togafitia ma le faʻaeteete.

(3) Faʻaaogaina i le sodium chloride ma alamanuia masima (suavai vai, vai sami, ma isi)

Chromium-nickel u'amea u'amea o lo'o i ai se fua fa'a'ala'au toniga e matua'i maualalo e fa'asaga i vaifofo sodium chloride e le tutusa ma laititi alkaline, suasami ma vai masima i se vevela ma fa'atonuga, ma e fa'aaogaina lautele. Ae ui i lea, e tatau ona maitauina e mafai ona tupu le pala i totonu o nisi tulaga.

Pamu u'ameao loʻo faʻaaogaina lautele i le alamanuia o meaʻai mo le taulimaina o le brine ma meaʻai masima. Ae ui i lea, e tatau ona gauai atu i faʻamatalaga faʻasalalau faʻasalalauga ma faʻailoga faʻamaufaʻailoga masini.

(4) Fa'aoga ile sodium hydroxide ma alamanuia alamanuia

Chromium-nickel austenitic uʻamea uʻamea e mafai ona tatalia sodium hydroxide i lalo 40-50% e uiga i 80 ° C, ae e le tetee i le maualuga-concentration ma maualuga-vevela alkali vai.

Chromium uamea u'amea na'o le talafeagai mo le maualalo o le vevela ma maualalo le fa'aogaina o vaifofo alkali.

E tatau ona gauai atu i le faʻafitauli o le crystallization medium.

(5) Fa'aoga i felauaiga suau'u

E tatau ona gauai atu i le viscosity o le ala, le filifilia o vaega paʻu, ma pe o le afi e iai manaʻoga e paʻu, ma isi.

(6) Fa'aaogāga i alamanuia tau vailaau

E mafai ona vaevaeina pamu fa'afoma'i i vaega nei e lua e tusa ai ma le auala e tu'uina atu ai le pamu:

O le tasi ituaiga o pamu vai masani, pamu vai vevela ma le faʻaogaina o le suavai otaota o loʻo faʻaaogaina i galuega a le malo, ma le isi ituaiga o pamu mo le felauaiga o ala o faʻasalalauga e pei o vailaʻau vailaʻau, vaʻavaʻa, vai mama, acids ma alkalis.

O le mea muamua e maualalo mana'oga mo pamu ma e mafai ona fa'aogaina e pamu o lo'o fa'aaogaina i mea fa'a vaila'au masani, ae o le mea mulimuli e maualuga atu mana'oga mo pamu. O pamu e tatau ona fetaui ma manaoga faʻapitoa mo pamu centrifugal o loʻo faʻaaogaina i masini faʻafomaʻi.

(7) Fa'aaogāga i fale gaosi mea'ai ma meainu

I totonu o le alamanuia o mea'ai ma meainu, o le ala e le fa'aleagaina pe vaivai vaivai, ae e le fa'atagaina le ele, ma o le mama o le ala e matua maualuga lava. I lenei tulaga, e mafai ona faʻaaogaina se pamu uʻamea.

Vaega fa'avae

1. O le fa'avasegaina o le va'aiga o le pamu o lenei fa'asologa o pamu e matua 'alofia ai le fa'aleagaina o le afi afi. O lenei mea e faʻamautinoa atoatoa ai le mautu ma le faʻatuatuaina o le gaioiga umi o le afi.

2. O lenei fa'asologa o pamu o lo'o i ai le fa'atuatuaina ma le fou o le fausaga o pamu pamu. O le pamu i luga ole laiga e mafai ona faigofie ona faʻaogaina le B5 fausaga faʻataʻitaʻiga afi e ave saʻo ai le pamu vai, ma o le pamu faʻalava e mafai ona faigofie ona faʻaogaina le B35 fausaga faʻataʻitaʻiga afi e ave saʻo ai le pamu vai.

7. O lenei faʻasologa o pamu e faʻaaogaina le mamanu faʻataʻitaʻiga sili ona lelei. O le faatinoga o le pamu e mautu ma lelei.

8. O le tino o le pamu, faʻapipiʻi pamu, impeller ma isi vaega o lenei faʻasologa o pamu o loʻo faʻamaonia saʻo e ala i le tuʻuina atu o tupe faʻafaigaluega, faʻatasi ai ma le maualuga o le saʻo, ala lamolemole ma foliga matagofie.

9. O faʻamau faʻapipiʻi, faʻamau, puipui ma isi vaega o lenei faʻasologa o pamu e faʻaaogaina mamanu lautele ma e sili ona fesuiaʻi.
