Malinga ndi ziwerengero, kupanga acrylic acid ku China kupitilira matani 2 miliyoni mu 2021, ndipo kupanga ma acrylic acid kudzapitilira matani 40 miliyoni.Makina opanga ma acrylate amagwiritsa ntchito ma esters a acrylic kuti apange ma esters a acrylic, kenako ma esters a acrylic amapangidwa kudzera mu zakumwa zoledzeretsa.Zomwe zimayimira ma acrylates ndi: butyl acrylate, isooctyl acrylate, methyl acrylate, ethyl acrylate ndi acrylic acid high absorbency resin.Pakati pawo, kuchuluka kwa kupanga kwa butyl acrylate ndi kwakukulu, kupanga m'nyumba kwa butyl acrylate kupitirira matani 1.7 miliyoni mu 2021. Yachiwiri ndi SAP, yopanga matani oposa 1.4 miliyoni mu 2021. Chachitatu ndi isooctyl acrylate, ndi kupanga opitilira matani 340,000 mu 2021. kupanga methyl acrylate ndi ethyl acrylate kudzakhala matani 78,000 ndi matani 56,000 motsatana mu 2021.

Pazogwiritsidwa ntchito pamakampani, acrylic acid makamaka amatulutsa ma ester a acrylic, ndipo butyl acrylate imatha kupangidwa ngati zomatira.Methyl acrylate imagwiritsidwa ntchito pamakampani opaka utoto, zomatira, emulsions za nsalu, ndi zina zambiri. Ethyl acrylate imagwiritsidwa ntchito ngati mphira wa acrylate ndi zomatira, zomwe zimaphatikizana ndi kugwiritsa ntchito methyl acrylate.Isooctyl acrylate imagwiritsidwa ntchito ngati zomatira zomatira kukakamiza, zomatira zomatira, ndi zina zotero. SAP imagwiritsidwa ntchito makamaka ngati utomoni wotsekemera kwambiri, monga matewera.

Malingana ndi zinthu zokhudzana ndi malonda a acrylate m'zaka ziwiri zapitazi, kuyerekezera kwamtengo wapatali (phindu la malonda / mtengo wogulitsa), zotsatirazi zikhoza kupezeka.

1. m'makampani a acrylate ku China, phindu lomwe limapeza kumapeto kwa zinthu zopangira ndipamwamba kwambiri, pomwe naphtha ndi propylene zili ndi phindu lalikulu.2021 naphtha profit margin ndi pafupifupi 56%, mapindu a propylene ndi pafupifupi 38%, ndipo mapindu a acrylic ali pafupi 41%.

2. Pakati pa zinthu za acrylate, phindu la methyl acrylate ndilopamwamba kwambiri.Phindu la methyl acrylate likufika pafupifupi 52% mu 2021, kutsatiridwa ndi ethyl acrylate ndi phindu la pafupifupi 30%.Malire a phindu la butyl acrylate ndi pafupifupi 9%, isooctyl acrylate ikutayika, ndipo phindu la SAP lili pafupi ndi 11%.

3. Pakati pa opanga acrylate, oposa 93% ali ndi zomera za acrylic acid kumtunda, pamene ena ali ndi zomera za acrylic acid, zomwe zambiri zimakhazikika m'mabizinesi akuluakulu.Kuchokera pakugawa kwa phindu lamakampani a acrylic kumawoneka, opanga ma acrylic okhala ndi acrylic acid amatha kuwonetsetsa kuti phindu lalikulu lamakampani a acrylate, pomwe opanga ma acrylate opanda acrylic acid okhala ndi acrylic acid ndi ochepa ndalama.

4, pakati pa opanga ma acrylate, malire a phindu la butyl acrylate yayikulu yakhalabe yokhazikika m'zaka ziwiri zapitazi, ndi phindu la 9% -10%.Komabe, chifukwa cha kusinthasintha kwa msika, mapindu a opanga ma ester apadera a acrylic ester amasinthasintha kwambiri.Izi zikusonyeza kuti phindu la msika la zinthu zazikulu ndilokhazikika, pamene zinthu zazing'ono zimakhala zosavuta kukhudzidwa ndi zinthu zomwe zimatumizidwa kunja ndi kusalinganika kwa zofuna za msika.

5, kuchokera pamakina opangira ma acrylate amatha kuwoneka, mabizinesi amapanga unyolo wamakampani acrylate, njira yayikulu yopangira butyl acrylate, pomwe ma acrylate apadera ndi SAP amapangidwa mwanjira yothandizira ya butyl acrylate, yomwe imatha kupititsa patsogolo kukana kwa msika. , komanso njira yabwino yopangira.

M'tsogolomu, methyl acrylate, ethyl acrylate ndi isooctyl acrylate ali ndi ntchito zawo zapansi pazitsulo zamakina acrylate, ndipo kugwiritsidwa ntchito kwapansi pamtsinje kumasonyeza kukula kwabwino.Kuchokera pakukula kwa msika ndi kuchuluka kwa kufunikira, methyl acrylate ndi ethyl acrylate ali ndi vuto lochulukirachulukira ndipo mawonekedwe amtsogolo ndiapakati.Pakalipano, butyl acrylate, isooctyl acrylate ndi SAP akadali ndi malo opangira chitukuko komanso ndizinthu zomwe zimakhala ndi phindu linalake muzinthu za acrylate m'tsogolomu.

Kwa mapeto a acrylic acrylic, propylene ndi naphtha, omwe deta yawo yaiwisi ikuwonjezeka pang'onopang'ono, phindu la naphtha ndi propylene likuyembekezeka kukhala lalikulu kuposa la acrylic acid.Chifukwa chake, ngati makampani apanga unyolo wamakampani a acrylate, ayenera kusamala kwambiri pakuphatikizidwa kwa unyolo wamakampani ndikudalira zopindulitsa zamakampani, padzakhala kuthekera kwa msika.
