Vinyl Acetate (IP), imadziwikanso kuti vinyl acetate kapena vinyl acetate, ndi madzi opanda utoto komanso owoneka bwino kutentha ndi kutentha. Monga chimodzi mwazinthu zogwiritsidwa ntchito kwambiri padziko lonse lapansi, ntchito imatha kutulutsa polyvinyl acetate remin (pvac), mowa wa polyvinyl, poto) ndi zotumphukira zina mwa polymerization ndi ena. Izi zimagwiritsidwa ntchito kwambiri pomanga, zolembedwa, makina, mankhwala opangira mankhwala ndi zowongolera nthaka.

Kusanthula konse kwa Vinyl acetate makampani opanga

Kukweza kwa makilogalamu a vinyl acel acetate makamaka ndi acetylene, acelec ndi hydrogen njira ya ethylene, ndipo imakhudzidwa ndi hydrogen mitengo yamitengo yamafuta. Imodzi ndikukonzekera kwa acetylene ndi gasi lachilengedwe kapena calcium carbide, kenako ndi acetic acid synthesis yotsika mtengo pang'ono kuposa carcium carbide. Pansi pamtunda makamaka pokonza zoledzera kwa polyvinyl, zoyera (polyvinyl evalsion), Vae, Eva ndi Molyvinyl.

1, zokutira zam'mwamba za vinyl acetate

Acetic acid ndiye kiyi yaiwisi yopanda pake, ndipo kugwiritsa ntchito kwake kumaphatikizidwa kwamphamvu ndi Vae. Zambiri zikuwonetsa kuti kuyambira 2010, kugwiritsidwa ntchito kwa China a acetic acid ndikusintha kwa matani asanu, owonjezera a quilic acid.

Pankhani yopumira, 25.6% ya acetic acid imagwiritsidwa ntchito kupanga pta (kuyeretsa Terefic acid M'zaka zaposachedwa, makampani opanga acetic acid amakhala okhazikika. Vinyl acetate amagwiritsidwa ntchito ngati gawo limodzi lofunikira kwambiri pamagawo a acetic acid.

2. Kupanga kotsika kwa vinyl acetate

Vinyl acetate amagwiritsidwa ntchito kwambiri kuti apange mowa wa polyvinyl ndi Eva, eva. yinyl acetate (mowa), eva), eva), eva), chifukwa Ma polima amatha kugwiritsidwa ntchito ngati zomata, pepala kapena nsalu zokazinga, mapepala osungunuka, mafilimu osungunuka, opatsa matayala, kupanga mapepala, kumanga ndi minda yamagalimoto. Zambiri zikuwonetsa kuti 65% ya vanyl acetate imagwiritsidwa ntchito kupanga mowa wa polyvinyl ndi 12% ya vinyl acetate amagwiritsidwa ntchito kupanga ma acevinyl.

Kusanthula kwa nyengo yaposachedwa ya msika wa vinyl

1, vinyl acetate mphamvu yopanga ndi kukhazikika

Kupitilira 60% ya zopanga vinyl kukhazikika kudera la Asia Poyerekeza ndi njira ya Acetylene, njira ya Ethylene ndiyochulukirapo komanso yopanda chilengedwe, yokhala ndi chilengedwe chapamwamba. Popeza mphamvu zamagetsi za malonda ku China makamaka zimadalira malasha Kupanga kwa Vinyl Airl Acetate kumawonjezeka kwambiri mu 2013-2016, pomwe osasintha mu 2016-2018. Makampani ogulitsa a vinyl a Vinyl amapereka zoopsa zochulukirapo, ndikugwiritsa ntchito kwambiri mu calcium carbide acetylene mayunitsi ndi makampani ambiri opanga mafakitale. 2020, China cha Vinyl acetate chogwiritsa ntchito matani a 2.65 miliyoni / chaka, pachaka cha pachaka.

2, mankhwala a vinyl acetate

Ponena za kugwirira ntchito, yi vinyl acetate posonyeza kusintha kwakukulu, ndipo msika wa vinyl ku China ukuwonetsa Kufunsira msika kwa Acetate kwakwera mwachangu, kugwiritsa ntchito chaka ndi chaka, chifukwa cha 2020 otsika afika matani 1.95 miliyoni, kuwonjezeka kwa 4.8% poyerekeza ndi 2019%.

3, mtengo wapakati wa msika wa vinyl

Kuchokera pakuwona mitengo yamsika ya vinyl, yomwe imakhudzidwa ndi kuthekera kowonjezera, mitengo yamakampani idakhazikika mu 2009-2020. Pofika EastAs ikuyamba kutsutsana, mitengo yamakampani yopanga mafakitale ichuluka kwambiri, mabizinesi apakhomo achulukanso kukulitsa kupanga, zomwe zimayambitsa kuchepa kwambiri. Mitengo yamtundu wa vinyl imagwera kwambiri mu 2015 ndi 2016, ndipo mu 2017, ndipo mu 2017, zomwe zidakhudzidwa ndi mfundo zachitetezo cha chilengedwe, mitengo yamakampani yopanga mafakitale idadutsa kwambiri. 2019, chifukwa cha kupezeka kokwanira pamsika wa Acetic Acid ndi Kuchepetsa Mafakitale Omwe Amatsika, ndipo mu 2020, Mitengo Yaku Earth Ager of National Mitengo Yoposa 12,000 fakitale yotseka kapena kuchedwa.

Mwachidule makampani a ethyl acetate

Zomera zaku China za Ethyl Acetate Chinesergrees a Sicopec's a Iscopec ali ndi matani azaka 1.22 miliyoni, omwe amawerengera 43% ya dzikolo, ndipo Ahui Wanwei Gululi lili ndi matani 750,000, chaka, kumawerengera 26.5%. Gawo lachilendo la nanjing balanes 350,000 / chaka, kuyanjana kwa 12%, ndi gawo laumwini la Mongolia Shualxin ndi Ningxia Ankel All 56000,000 / Chaka cha 20%. Opanga zam'madzi a ku Rinyl amapezeka kumpoto chakumadzulo, East China ndi kumwera chakumadzulo, ndi Kumpoto chakumadzulo kwa 51.6%, Kumpoto China Akaunti ya 21.2%.

Kusanthula kwa malingaliro a vinyl

1, Eva Otsika Pempho

Eva kutsikira kwa vinyl acetate angagwiritsidwe ntchito ngati filimu ya PL cell. Malinga ndi mphamvu yatsopano ya mphamvu yapadziko lonse, Eva kuchokera ku Ethylene ndi Vinyl Acetate Otsatsa, etc. 2020 kwa othandizira a Photovovoltal chaka chatha, opanga mitu iwiri alengeza kukula kwa zithunzi, ndipo ndi njira zowonjezera za Photovoltaic kuposa momwe akuyembekezeredwa, Eva Akufuna Kukula. Zikuyembekezeka kuti matani 800,000 a Eva adzaikidwa mu 2021. Malinga ndi kuwerengera, kukula kwa matani a eva opanga vinyl oncy, zomwe zimayendetsa matani a acetic a Acetic.

2, vinyl acetate wopitilira, zinthu zazitali kwambiri zimafunikirabe kuyimitsidwa

China ili ndi vuto lalikulu la vinyl acetate, ndi zinthu zapamwamba kwambiri zimafunikirabe kuyimitsidwa. Pakadali pano, kupezeka kwa vanyl acetate ku China kumapitilira zofuna zake, zomwe zimachulukitsa komanso zopanga zowonjezera zimadalira kugwiritsidwa ntchito kunja. Popeza kufalikira kwa luso lopanga vinyl acethate mu 2014, kusinthitsa kwa China ku China kumawonjezera kwambiri, ndipo zinthu zina zochokera ku Vinyl zasinthidwa ndi mphamvu zapabanja. Kuphatikiza apo, kunja kwa China ku China kumakhala kochepa kwambiri, pomwe zotuluka ndizogulitsa kwambiri. Pakadali pano, China ikufunika kudalira kunja kwa zinthu zomaliza za vinyl acelete zinthu zolimbitsa thupi, ndipo malonda a vinyl acetate akadali malo achitukuko pamsika wotsiriza.
