Phthalic Anhydride (PA) Zoo Tshaj Plaws: Lub Tsev Tseem Ceeb rau Cov Polymers thiab Cov Tshuaj Uas Muaj Kev Ua Haujlwm Zoo
Cov Ntawv Thov Tseem Ceeb
1. Cov Polyester Resins thiab Thermoplastics: Lub Hauv Paus ntawm Cov Polymers Kev Lag Luam
Phthalic Anhydride feem ntau yog siv rau hauv kev tsim cov unsaturated polyester resins (UPRs), ib qho tseem ceeb hauv fiberglass-reinforced plastics (FRPs):
Cov Ntawv Thov FRP:
Hauv kev tsim tsheb (piv txwv li, cov chaw tsim tsheb European), UPRs uas tau los ntawm PA yog siv los tsim cov vaj huam sib luag lub cev sib dua, cov bumpers, thiab cov khoom hauv qab lub hood, txo qhov hnyav ntawm lub tsheb thiab txhim kho kev siv roj.
Hauv lub zog cua, PA-based resins yog qhov tseem ceeb rau kev tsim cov hniav cua turbine, muab lub zog siab thiab kev ruaj khov kom tiv taus huab cua hnyav hauv cov liaj teb hauv hiav txwv (piv txwv li, North Sea projects).
Cov Khoom Siv Thermoplastic:
Ua haujlwm ua tus hloov kho hauv kev tsim cov polyvinyl chloride (PVC), txhim kho kev ywj pheej thiab kev ua haujlwm. Piv txwv li, hauv cov chaw tsim khoom yeeb nkab PVC hauv Es Xias, cov yas ua PA txhim kho kev tiv thaiv kev cuam tshuam ntawm cov yeeb nkab rau cov dej thiab cov kav dej phwj.
2. Cov Xim, Cov Tshuaj Txhuam, thiab Cov Nplaum: Kev Ua Tau Zoo thiab Kev Ruaj Khov
Cov roj alkyd:
PA yog ib qho khoom xyaw tseem ceeb hauv cov alkyd resins, siv rau hauv cov xim pleev tsev (piv txwv li, cov xim pleev tsev sab nraud hauv North America) rau lawv qhov kev tiv thaiv huab cua zoo heev thiab khaws cov xim. Cov txheej txheem alkyd kuj tseem tiv thaiv cov hlau hauv cov chaw lag luam (piv txwv li, choj, tshuab) los ntawm kev xeb.
Cov txheej txheem epoxy:
Hauv cov txheej txheem sib xyaw, PA derivatives txhim kho qhov kev nplaum thiab kev tiv thaiv tshuaj lom neeg ntawm cov kab ke epoxy, qhov tseem ceeb rau hauv pem teb hauv chav tshuaj thiab cov chaw ua zaub mov.
Cov nplaum:
Siv rau hauv 热熔胶 (cov nplaum kub-yaj) rau kev ntim khoom thiab kev khi phau ntawv, PA txhim kho qhov chaw yaj thiab lub zog sib txuas, ua kom muaj kev ua tau zoo hauv cov kab tsim khoom ceev ceev (piv txwv li, kev lag luam ntim khoom European).
3. Cov Tshuaj Yas thiab Cov Tshuaj Tshwj Xeeb: Txhim Kho Cov Khoom Siv
Cov Phthalate Plasticizers:
PA yog cov ua ntej rau kev tsim cov diisononyl phthalate (DINP) thiab diethyl phthalate (DEP), siv dav hauv cov khoom PVC xws li cov khoom ua si, rooj zaum, thiab cov khoom siv kho mob. Cov yas no ua kom muaj kev ywj pheej thaum tswj hwm kev ua raws li EU REACH cov cai rau kev lom tsawg (piv txwv li, hauv cov khoom menyuam yaus).
Cov Tshuaj Nruab Nrab:
Hauv kev tsim tshuaj, PA derivatives yog siv rau hauv kev tsim cov tshuaj xws li cov tshuaj tiv thaiv kev o thiab cov tshuaj tua kab mob fungal. Piv txwv li, nws ua lub luag haujlwm hauv kev tsim cov tshuaj tua kab mob cephalosporin, uas tseem ceeb rau kev kho cov kab mob bacterial thoob ntiaj teb.
4. Kev Ua Liaj Ua Teb thiab Kev Tswj Kab Tsuag: Kev Dais Teeb Meem Kom Ruaj Khov
Cov tshuaj tua kab thiab cov tshuaj tua kab mob fungal:
Cov tshuaj PA-based siv rau hauv kev tsim cov khoom tiv thaiv qoob loo, xws li cov tshuaj pyrethroids hluavtaws rau kev tswj kab. Hauv cov liaj teb taum pauv South American, cov tshuaj no pab tiv thaiv cov qoob loo ntawm cov kab tsuag thaum txo qis kev cuam tshuam rau ib puag ncig.
Cov Polymers uas lwj tau:
Ua ib lub monomer hauv cov yas uas lwj tau, PA pab txhawb rau kev tsim cov khoom ntim khoom uas zoo rau ib puag ncig (piv txwv li, cov thawv ntim khoom noj uas ua los ntawm cov nroj tsuag) uas txo kev vam khom rau cov khoom siv roj av.
5. Cov Ntawv Thov Rau Chav Kuaj Mob Thiab Kev Tshawb Fawb
Kev Tsim Khoom Siv Organic:
PA yog ib qho tshuaj reagent uas siv tau ntau yam hauv cov chaw kuaj mob thiab chaw kuaj mob hauv kev lag luam rau cov tshuaj tiv thaiv xws li Friedel-Crafts acylation, uas siv los ua cov ketones thiab cov xim pleev kom muaj ntxhiab. Nws kuj tseem pab txhawb kev tsim cov phthalimide, uas yog ib qho tseem ceeb hauv kev tshawb fawb txog tshuaj thiab kev ua liaj ua teb.
Kev Tshawb Fawb Txog Polymer:
Siv rau hauv cov chaw kuaj polymer los kawm txog kev sib raug zoo ntawm cov qauv thiab cov khoom ntawm polyesters, ua rau muaj kev txhim kho cov khoom siv siab heev rau aerospace thiab electronics (piv txwv li, cov txheej tiv taus cua sov rau satellites).
