Incazelo:
I-Isophthalic acid iyinhlanganisela yezinto eziphilayo enefomula i-C6H4(CO2H)2. Lesi siqina esingenambala siyi-isomer ye-phthalic acid kanye ne-terephthalic acid. Lawa ma-dicarboxylic acid anuka kamnandi asetshenziswa njengezinto ezandulelayo (ngendlela yama-acyl chloride) kuma-polymer abalulekile kwezentengiselwano, isibonelo, i-Nomex engashisi. Ixutshwe ne-terephthalic acid, i-iso phthalic acid isetshenziswa ekukhiqizweni kwama-resin amabhodlela okuphuza. I-poly benzimidazole ye-polymer esebenza kahle kakhulu ikhiqizwa yi-iso phthalic acid.

Ukusetshenziswa
I-Isophthalic acid isetshenziswa njenge-intermediate yama-polyester angagcwele asebenza kahle kakhulu, ama-resins okumboza, upende oluqinile oluphezulu, ama-gel coats kanye ne-modifier ye-polyethylene terephthalate yamabhodlela. Isebenza njengezinto ezisekelayo ze-nomex ezingashi futhi isetshenziswa ekulungiseleleni i-polybenzimidazole ye-polymer esebenza kahle kakhulu. Iphinde isetshenziswe njengokufaka ekukhiqizeni izinto zokuvikela ukushisa.
I-Purified Isophthalic Acid (PIA) isetshenziswa kakhulu njenge-medium ye-UPR esebenza kahle kakhulu, ama-resin okumboza, upende oluqinile oluphezulu, ama-gel coats, kanye ne-modifier ye-PET yamabhodlela.
Ukupakisha
25KG/Isikhwama noma ngokwezidingo zamakhasimende.
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
