Ukusetyenziswa kweMaleic Anhydride

I-anhydride ye-Maleic sisixhobo esibalulekileyo sekhemikhali yendalo esineendlela ezahlukeneyo zokusetyenziswa kumashishini amaninzi. Ukusetyenziswa kwayo okuphambili zezi zilandelayo:

1. Ukuveliswa kwezinto zePolymer

IiResins zePolyester ezingagcwaliyo (UPR): Le yeyona ndawo inkulu yokusetyenziswa kwe-anhydride ye-maleic. I-MA isabela kunye nee-diols (ezifana ne-ethylene glycol, i-propylene glycol) ukuze zenze ii-resins ze-polyester ezingagcwaliyo. Ezi resins zisetyenziswa kakhulu ekwenzeni iiplastiki eziqiniswe nge-fiberglass (FRP), ezisetyenziswa kwiinqanawa, kwiindawo zeemoto, kwizixhobo zeekhemikhali, nakwizinto zokwakha ngenxa yamandla azo aphezulu, ukumelana nokugqwala, kunye neempawu ezikhaphukhaphu.

Ii-Alkyd Resins: I-Maleic anhydride isetyenziswa ekuhlanganiseni ii-alkyd resins, eziyinxalenye ebalulekileyo kwiipeyinti zokuhombisa, ii-coatings zemizi-mveliso, kunye nee-varnishes. Ii-alkyd resins ziphucula ukunamathela, ukukhazimla, kunye nokuqina kwee-coatings.

Ezinye iiPolymers: Zingadityaniswa ngee-monomers ezifana ne-styrene, i-vinyl acetate, kunye nee-acrylic esters ukuvelisa ii-copolymers. Ezi copolymers zisetyenziswa kwi-adhesives, kwi-textile auxiliaries, nakwi-plastic modifiers ukuphucula ukusebenza kwemveliso (umz., ukumelana nobushushu, ukuguquguquka).

2. Izinto eziPhakathi zeeKhemikhali

Ukuveliswa kwee-Organic Acids: I-Cis-Butenedioic Anhydride idlula kwi-hydrolysis ukuze yenze i-maleic acid, kwaye i-hydrogenation engaphezulu inokuvelisa i-succinic acid okanye i-tetrahydrophthalic anhydride. Ezi mveliso zizinto ezibalulekileyo ekuhlanganisweni kwamayeza, izibulali-zinambuzane kunye ne-surfactants.

Ukwenziwa kweZibulali-zinambuzane: I-Maleic Anhydride Acid sisixhobo esisetyenziswa ekuveliseni izibulali-zinambuzane ezithile, ezifana nezibulali-zinambuzane (umz., ii-glyphosate intermediates) kunye nezibulali-zinambuzane, ezinegalelo ekulawuleni izinambuzane kwimveliso yezolimo.

Izinto eziPhakathi zeMithi: I-Maleic Acid Anhydride isetyenziswa ekuhlanganiseni ezinye izinto zokwenza amayeza, ezifana namayeza okulwa nokuvuvukala kunye neevithamini, idlala indima ebalulekileyo kwishishini lemithi.

3. Amashishini ePhepha kunye neLaphu

I-Agent yokulinganisa iphepha: Ii-copolymers ze-anhydride ze-Maleic zisetyenziswa njengee-agent zokulinganisa iphepha zangaphakathi. Zinokuphucula ukumelana namanzi kunye nokuprintwa kwephepha, okwenza lifaneleke kwiipakethe zephepha, iphepha lenkcubeko, kunye nezinye iintlobo zephepha.

Izincedisi zeLaphu: 2 5-I-Furandine isetyenziselwa ukuvelisa izinto zokugqiba ilaphu, ezifana nezinto ezimelana nokugoba kunye nezinto ezimelana nokuncipha. Ezi zinto zinokuphucula ukunxibeka kunye nokuqina kwelaphu, ingakumbi kwilaphu lekotoni kunye ne-polyester.

4. Ishishini leoyile negesi

I-Corrosion Inhibitor: Ii-Maleic anhydride derivatives (umz., ii-maleic anhydride-vinylpyrrolidone copolymers) zisetyenziswa njengezithinteli zokubola kwi-oyile kunye nemibhobho yeoyile negesi. Zinokwenza ifilimu ekhuselayo kumphezulu wesinyithi, zinciphise ukubola okubangelwa ngamanzi kunye nemidiya ebolayo.

I-Scale Inhibitor: I-Cis-Butenedioic Anhydrides I-Maleic Anhydride ikwasetyenziswa ekulungiseleleni izithinteli zesikali, ezithintela ukwakheka kwesikali (njenge-calcium carbonate, i-calcium sulfate) kwizixhobo ze-oyile kunye nemibhobho, ukuqinisekisa ukusebenza kakuhle kwemveliso.

5. Ezinye izicelo

Izongezo zokutya: Ezinye izinto eziphuma kwi-maleic anhydride (umz., i-succinic acid, eveliswa kwi-maleic anhydride) zisetyenziswa njengezongezo zokutya, ezifana ne-acidulants kunye nezithambisi zencasa, kwishishini lokutya.

Izithambisi Zokuthambisa: Iiflakes zeMaleic Anhydride zisetyenziselwa ukwenza izongezo zokuthambisa, ezifana nezinyibilikisi kunye nee-antioxidants, ezinokuphucula ukusebenza kunye nobomi benkonzo yeeoyile zokuthambisa.
