Tlhaloso e Khutšoanyane:

Kakaretso ea Sehlahisoa

Phthalic Anhydride (PA) ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse hlahisoang haholo ke oxidation ea ortho-xylene kapa naphthalene. E bonahala e le 'mala o mosoeu oa kristale o nang le monko o monate o fokolang. PA e sebelisoa haholo ha ho etsoa li-plasticizers, li-resin tsa polyester tse sa sebetseng, li-alkyd resin, dae le li-pigments, e leng se etsang hore e be karolo ea bohlokoa ea lipakeng indastering ea lik'hemik'hale.

Likarolo tsa Bohlokoa

• Reactivity e Phahameng:PA e na le lihlopha tsa anhydride, tse arabelang habonolo ka lino tse tahang, li-amine le metsoako e meng ho etsa li-ester kapa li-amides.
• Solubility e Ntle:E qhibiliha ka metsing a chesang, li-alcohol, li-ethers le lihlahisoa tse ling tsa tlhaho.
• Botsitso:E tsitsitse tlas'a maemo a omileng empa hydrolyzes butle ho phthalic acid boteng ba metsi.
• Mefuta-futa:E sebelisoa ha ho etsoa lihlahisoa tse ngata tsa lik'hemik'hale, e leng se etsang hore e be e fapaneng haholo.

Lisebelisoa

1. Lisebelisoa tsa polasetiki:E sebelisoa ho hlahisa li-phthalate esters (mohlala, DOP, DBP), tse sebelisoang haholo lihlahisoa tsa PVC ho ntlafatsa ho fetoha ha maemo le ho sebetsa hantle.
2. Li-resin tsa polyester tse sa sebelisoang:E sebelisoa ha ho etsoa likhalase tsa fiberglass, likoahelo le likhomaretsi, e fana ka thepa e ntle ea mochini le khanyetso ea lik'hemik'hale.
3. Alkyd Resins:E sebelisoa lipenteng, lirafshoa le li-varnish, tse fanang ka ho khomarela hantle le ho benya.
4. Dyes le Pigments:E sebetsa e le setsi sa ho kopanya lidae le li-pigments tsa anthraquinone.
5. Lisebelisoa tse ling:E sebelisoa ha ho etsoa li-intermediate tsa meriana, chefo e bolaeang likokoanyana le litlolo tse nkhang hamonate.

Packaging & Storage

• Sephutheloana:E fumaneha ka 25 kg / mokotla, 500 kg / mokotla, kapa mekotla ea lithane. Likhetho tsa ho paka ka tloaelo lia fumaneha ha u kopa.
• Polokelo:Boloka sebakeng se pholileng, se omeletseng, se nang le moea o motle. Qoba ho kopana le mongobo. Mocheso o khothalletsoang oa polokelo: 15-25 ℃.

Tšireletseho & Mehopolo ea Tikoloho

• Ho teneha:PA e halefisa letlalo, mahlo le tsamaiso ea ho hema. Thepa e nepahetseng ea ts'ireletso (mohlala, liatlana, likhalase, lisebelisoa tsa ho hema) li tlameha ho apesoa nakong ea ts'ebetso.
• Ho chesa:E tuka empa e sa chese haholo. Qoba hole le malakabe a bulehileng le mocheso o phahameng.
• Tšusumetso ea Tikoloho:Lahla litšila ho latela melao ea tikoloho ea lehae ho thibela tšilafalo.

Iteanye le rona

Ho fumana lintlha tse ling kapa ho kopa sampole, ka kopo ikopanye le sehlopha sa rona sa barekisi. Re ikemiselitse ho fana ka lihlahisoa tsa boleng bo holimo le litšebeletso tse ntle haholo!
