Réamhrá faoi Cumas PVC sa tSín agus go Domhanda
According to the statistics in 2020, the global total PVC production capacity reached 62 million tons and the total output reached 54 million tons. All the reduction in output means that the production capacity did not run 100%. Mar gheall ar thubaistí nádúrtha, beartais áitiúla agus fachtóirí eile, ní mór an t-aschur a bheith níos lú ná an cumas táirgthe. Due to the high production cost of PVC in Europe and Japan, the global PVC production capacity is mainly concentrated in Northeast Asia, of which China has about half of the global PVC production capacity. According to wind data, in 2020, China, the United States and Japan are important PVC production areas in the world, with production capacity accounting for 42%, 12% and 4% respectively. In 2020, tá na trí fhiontar is fearr sa PVC domhanda ann... -
Is cineál plaisteach é PVC a úsáidtear go forleathan in ábhair thógála. Therefore, it will not be replaced for a long time in the future, and it will have great application prospects in less developed areas in the future. As we all know, there are two ways to produce PVC, one is the international common ethylene method, and the other is the unique calcium carbide method in China. Is peitriliam den chuid is mó iad foinsí an mhodha eitiléine, agus is iad na foinsí a bhaineann le modh cairbíd cailciam gual, aolchloch agus salann den chuid is mó. Tá na hacmhainní seo comhchruinnithe den chuid is mó sa tSín. For a long time, China's PVC of calcium carbide method has been in an absolute leading position. Especially from 2008 to 2014, China's PVC production capacity of calcium carbide method has been increasing, but it has also brought ... -
Polyvinyl chloride (PVC) is a polymer polymerized by vinyl chloride monomer (VCM) in peroxide, azo compound and other initiators or according to the free radical polymerization mechanism under the action of light and heat. Tugtar roisín clóiríde vinile ar homopolymer clóiríd vinile agus ar chóipín clóiríde vinile. Ba é PVC an plaisteach ginearálta is mó ar domhan, a úsáideadh go forleathan. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging film, bottles, foaming materials, sealing materials, fibers and so on. According to the different application scope, PVC can be divided into: general-purpose PVC resin, high degree of polymerization PVC resin and ... -
Leanann fuinneog arbatráiste onnmhairithe PVC ag oscailt
I dtéarmaí gné soláthair, chomhdhúile cailciam, an tseachtain seo caite, laghdaíodh praghas margaidh príomhshrutha chomhdhúile cailciam 50-100 yuan / tonna. Bhí ualach oibriúcháin foriomlán na bhfiontar chomhdhúile cailciam sách cobhsaí, agus ba leor an soláthar earraí. Affected by the epidemic, the transportation of calcium carbide is not smooth, the factory price of enterprises is lowered to allow profit transportation, the cost pressure of calcium carbide is large, and the short-term decline is expected to be limited. Tá méadú tagtha ar ualach tosaithe na bhfiontar PVC in aghaidh an tsrutha. The maintenance of most enterprises is concentrated in the middle and late April, and the start-up load will remain relatively high in the short term. Ar chuir an eipidéim isteach air, tá an t-uas oibriúcháin... -
Tá an fhoireann i Chemdo ag obair le chéile chun an eipidéim a chomhrac
I mí an Mhárta 2022, chuir Shanghai dúnadh agus rialú na cathrach i bhfeidhm agus d'ullmhaigh sé an "plean imréitigh" a dhéanamh. Anois go bhfuil sé thart ar lár mhí Aibreáin, ní féidir linn ach breathnú ar an radharcra álainn lasmuigh den fhuinneog sa bhaile. Ní raibh aon duine ag súil go n-éireodh treocht an eipidéim i Shanghai níos mó agus níos déine, ach ní chuirfidh sé seo stop le díograis an Chemdo ar fad san earrach faoin eipidéim. Cuireann foireann iomlán Chemdo "obair sa bhaile" i bhfeidhm. Oibríonn gach roinn le chéile agus comhoibríonn siad go hiomlán. Déantar cumarsáid oibre agus aistriú ar líne i bhfoirm físeáin. Cé go bhfuil ár n-aghaidheanna sa físeán i gcónaí gan makeup, cuireann an dearcadh tromchúiseach i leith na hoibre thar maoil ar an scáileán. Omi bocht... -

Slabhra tionscal aigéad pholalachtach (PLA) na Síne i 2021
1. Forbhreathnú ar an slabhra tionsclaíoch: Is é an t-ainm iomlán d'aigéad polalactic aigéad lachtach pola nó aigéad lachtaigh pola. Is ábhar poileistear ard-mhóilíneach é a fhaightear trí pholaiméiriú le haigéad lachtaigh nó lachtadh dimer aigéad lachtaigh mar mhonaiméir. Baineann sé le hábhar ard-mhóilíneach sintéiseach agus tá tréithe bunús bitheolaíoch agus díghrádaithe aige. Faoi láthair, is plaisteach in -bhithmhillte é aigéad polalactic leis an tionsclaíocht is aibí, an t -aschur is mó agus an t -aschur is mó a úsáidtear ar fud an domhain. Is é an t -amhábhar bunúsach an tionscal aigéad polalactic in aghaidh srutha, mar shampla arbhar, cána siúcra, biatas siúcra, srl. -
Tá an polaiméir in -bhithmhillte PBAT ag bualadh an ama mór
The perfect polymer—one that balances physical properties and environmental performance—doesn't exist, but polybutylene adipate co-terephthalate (PBAT) comes closer than many. Producers of synthetic polymers have for decades failed to stop their products from ending up in landfills and oceans, and they are now under pressure to take responsibility. Tá iarrachtaí á ndéanamh ag go leor acu chun an athchúrsáil a threisiú chun stop a chur le léirmheastóirí. Tá gnólachtaí eile ag iarraidh dul i ngleic leis an bhfadhb dramhaíola trí infheistíocht a dhéanamh i bplaistigh bhith -bhithmhillte ar amhail aigéad polalachtach (PLA) agus polyhydroxyalkanoate (PHA), ag súil go maolóidh díghrádú nádúrtha cuid den dramhaíl ar a laghad. Ach tá constaicí roimh athchúrsáil agus bithpholaiméirí araon. Despite years... -
