Anhydride ea Phthalic ea Premium (PA): Moaho oa Bohlokoa bakeng sa Li-polymer le Lik'hemik'hale tse nang le Ts'ebetso e Phahameng
Masimo a Maholo a Kopo
1. Li-resin tsa Polyester le Thermoplastics: Motheo oa Li-polymer tsa Indasteri
Phthalic Anhydride e sebediswa haholoholo tlhahisong ya di-resin tsa polyester tse sa tlatswang (UPRs), e leng karolo ya bohlokwa dipolasetiking tse matlafaditsweng ka fiberglass (FRPs):
Likopo tsa FRP:
Tlhahisong ea likoloi (mohlala, bahlahisi ba likoloi ba Europe), li-UPR tse tsoang ho PA li sebelisoa ho hlahisa liphanele tsa 'mele tse bobebe, li-bumper, le likarolo tse ka tlas'a sekoahelo, ho fokotsa boima ba koloi le ho ntlafatsa ts'ebeliso e ntle ea mafura.
Ka matla a moea, li-resin tse thehiloeng ho PA lia hlokahala bakeng sa ho etsa mahare a turbine ea moea, li fana ka matla a phahameng le ho tšoarella ho mamella maemo a leholimo a feteletseng mapolasing a lebōpong la leoatle (mohlala, merero ea Leoatle le ka Leboea).
Lisebelisoa tsa Thermoplastic:
E sebetsa e le phetoho tlhahisong ea polyvinyl chloride (PVC), e ntlafatsa ho tenyetseha le ho sebetsa habonolo. Mohlala, lifekthering tsa liphaephe tsa PVC tsa Asia, li-plasticizer tse thehiloeng ho PA li ntlafatsa khanyetso ea tšusumetso ea liphaephe bakeng sa litsamaiso tsa metsi le likhoerekhoere.
2. Pente, Liaparo le Likhomaretsi: Tshebetso le ho Tšoarella
Li-resin tsa Alkyd:
PA ke motsoako oa bohlokoa oa li-resin tsa alkyd, tse sebelisoang penteng ea meralo (mohlala, pente ea ntlo ea kantle Amerika Leboea) ka lebaka la ho hanyetsa boemo ba leholimo hantle le ho boloka 'mala. Liaparo tse thehiloeng ho alkyd li boetse li sireletsa libaka tsa tšepe libakeng tsa indasteri (mohlala, marokho, mechini) ho tsoa mafomeng.
Liaparo tsa Epoxy:
Likoahelong tse kopantsoeng, li-derivatives tsa PA li ntlafatsa ho khomarela le ho hanyetsa lik'hemik'hale tsa litsamaiso tsa epoxy, e leng tsa bohlokoa bakeng sa fatše likamoreng tsa ho hloekisa meriana le lits'ebeletsong tsa ho lokisa lijo.
Likhomaretsi:
E sebelisoa ho 热熔胶 (likhomaretsi tse qhibilihang ka ho chesang) bakeng sa ho paka le ho tlama libuka, PA e ntlafatsa ntlha ea ho qhibiliha le matla a ho tlama, e netefatsa ts'ebetso e tšepahalang mefuteng ea tlhahiso e potlakileng (mohlala, indasteri ea ho paka ea Europe).
3. Lisebelisoa tsa polasetiki le lik'hemik'hale tse ikhethang: Ho ntlafatsa thepa ea thepa
Lisebelisoa tsa polasetiki tsa Phthalate:
PA ke selelekela sa tlhahiso ea diisononyl phthalate (DINP) le diethyl phthalate (DEP), tse sebelisoang haholo lihlahisoa tsa PVC joalo ka lintho tsa ho bapala, upholstery le lisebelisoa tsa bongaka. Li-plasticizer tsena li ntlafatsa ho tenyetseha ha li ntse li boloka ho latela melao ea EU REACH bakeng sa chefo e tlase (mohlala, lihlahisoa tsa bana).
Meriana e Mahareng:
Motswakong wa meriana, di-derivatives tsa PA di sebediswa tlhahisong ya meriana e kang di-anti-inflammatory agents le di-antifungal complexes. Mohlala, e bapala karolo tlhahisong ya di-antibiotic tsa cephalosporin, e leng tsa bohlokwa bakeng sa ho phekola ditshwaetso tsa baktheria lefatsheng ka bophara.
4. Temo le Taolo ea Likokoanyana: Litharollo tse Tšoarellang
Libolaea-likokoanyana le Libolaea-fungi:
Lik'hemik'hale tse thehiloeng ho PA li sebelisoa ho etseng lihlahisoa tsa tšireletso ea lijalo, tse kang li-pyrethroids tsa maiketsetso bakeng sa taolo ea likokoanyana. Mapolasing a soya a Amerika Boroa, metsoako ena e thusa ho sireletsa lijalo ho likokoanyana tse hlaselang ha ka nako e ts'oanang e fokotsa tšusumetso ea tikoloho.
Li-polymer tse bolang:
Jwalo ka monomer ya dipolasetiki tse bolang, PA e kenya letsoho ntshetsopeleng ya thepa ya ho paka e sireletsang tikoloho (mohlala, dijana tsa dijo tse thehilweng dimeleng) tse fokotsang ho itshetleha hodima dihlahiswa tse thehilweng peteroleng.
5. Likopo tsa Laboratori le Lipatlisiso
Tlhahiso ea Lintho tse Hloahloa:
PA ke sesebelisoa se sebetsang ka ho feto-fetoha lilaboratoring tsa thuto le tsa indasteri bakeng sa liketso tse kang Friedel-Crafts acylation, e sebelisetsoang ho kopanya li-ketone tse nkhang hamonate le lidae. E boetse e nolofalletsa tlhahiso ea phthalimide, e leng karolo ea bohlokoa lipatlisisong tsa meriana le tsa agrochemical.
Saense ea Polymer:
E sebelisoa lilaboratoring tsa polymer ho ithuta likamano tsa sebopeho le thepa ea li-polyester, e nolofalletsang nts'etsopele ea thepa e tsoetseng pele bakeng sa lifofane le lisebelisoa tsa elektroniki (mohlala, liphahlo tse hanelang mocheso bakeng sa li-satellite).
