Ukusetyenziswa kwe-resin ye-pvc yokuncamathisela.
Kuqikelelwa ukuba ngo-2000, ukusetyenziswa okupheleleyo kwemarike ye-PVC paste resin yehlabathi bekumalunga ne-1.66 yezigidi zeetoni. E-China, i-PVC paste resin ikakhulu inezicelo ezilandelayo: Ishishini lesikhumba sokwenziwa: ukubonelela ngemarike iyonke kunye nokulinganisela kwemfuno. Nangona kunjalo, xa ichaphazeleka kukuphuhliswa kwesikhumba se-PU, imfuno yesikhumba sokwenziwa eWenzhou nakwezinye iindawo eziphambili zokusetyenziswa kwe-paste resin ixhomekeke kwimida ethile. Ukhuphiswano phakathi kwesikhumba se-PU kunye nesikhumba sokwenziwa lunamandla. Ishishini lesikhumba somgangatho: Lichaphazeleka kukuncipha kwemfuno yesikhumba somgangatho, imfuno ye-paste resin kweli shishini iye yehla minyaka le kwiminyaka yakutshanje. Ishishini lezinto zeglavu: imfuno inkulu kakhulu, ikakhulu ingeniswa kwamanye amazwe, eyokucutshungulwa kwe-mate ebonelelweyo... -
Isityalo se-polyethylene esinobunzima obuziitoni ezingama-800,000 saqalwa ngempumelelo ngexesha elinye lokutya!
Isityalo se-polyethylene esigcweleyo seGuangdong Petrochemical esiziitoni ezingama-800,000 ngonyaka sisityalo sokuqala se-polyethylene esigcweleyo sePetroChina esinomgca ophindwe kabini "wentloko enye nemisila emibini", kwaye sikwasisityalo sesibini se-polyethylene esigcweleyo esinamandla amakhulu emveliso eTshayina. Esi sixhobo samkela inkqubo ye-UNIPOL kunye nenkqubo yebhedi yegesi yesigaba esinye. Sisebenzisa i-ethylene njengezinto ezisetyenziswa kakhulu kwaye sinokuvelisa iintlobo ezili-15 zezinto ze-polyethylene ze-LLDPE kunye ne-HDPE.

Ukusetyenziswa kwe-caustic soda kubandakanya iinkalo ezininzi.
I-Caustic soda ingahlulwa ibe yi-flake soda, i-granular soda kunye ne-solid soda ngokwemo yayo. Ukusetyenziswa kwe-caustic soda kubandakanya iinkalo ezininzi, oku kulandelayo kukwazisa ngeenkcukacha: 1. I-petroleum ecociweyo. Emva kokuhlanjwa nge-sulfuric acid, iimveliso zepetroleum zisenazo ezinye izinto ezine-asidi, ekufuneka zihlanjwe ngesisombululo se-sodium hydroxide kwaye emva koko zihlanjwe ngamanzi ukuze kufunyanwe iimveliso ezicociweyo. 2. ukuprinta kunye nokudaya Isetyenziswa kakhulu kwiidayi ze-indigo kunye needayi ze-quinone. Kwinkqubo yokudaya iidayi ze-vat, isisombululo se-caustic soda kunye ne-sodium hydrosulfite kufuneka zisetyenziswe ukuzinciphisa zibe yi-leuco acid, kwaye emva koko zifakwe kwimo yokuqala yokunganyibiliki ngee-oxidants emva kokudaya. Emva kokuba ilaphu lekotoni liphathwe ngesisombululo se-caustic soda, i-wax, i-grease, i-starch kunye nezinye izinto ... -
Ukubuyiselwa kwemfuno yePVC kwihlabathi liphela kuxhomekeke eTshayina.
Ukungena ngo-2023, ngenxa yemfuno ecothayo kwiindawo ezahlukeneyo, imakethi ye-polyvinyl chloride (PVC) yehlabathi isajongene nokungaqiniseki. Ngexesha elininzi lowama-2022, amaxabiso e-PVC e-Asia nase-United States abonise ukwehla okukhulu kwaye ehla ngaphambi kokungena ngo-2023. Ukungena ngo-2023, phakathi kweendawo ezahlukeneyo, emva kokuba i-China ilungise imigaqo-nkqubo yayo yokuthintela nokulawula ubhubhane, imakethi ilindele ukuphendula; i-United States inokunyusa ngakumbi amazinga enzala ukuze ilwe nokunyuka kwamaxabiso kwaye inciphise imfuno ye-PVC yasekhaya e-United States. I-Asia, ekhokelwa yi-China, kunye ne-United States zandise ukuthunyelwa kwe-PVC ngaphandle phakathi kwemfuno ebuthathaka yehlabathi. Ngokuphathelele iYurophu, lo mmandla usaza kujongana nengxaki yamaxabiso aphezulu amandla kunye nokwehla kwamandla emali, kwaye mhlawumbi akuyi kubakho kubuyiselwa okuzinzileyo kwimida yenzuzo kushishino. ... -
Iyintoni impembelelo yenyikima enamandla eTurkey kwi-polyethylene?
ITurkey lilizwe elijikeleze iAsia neYurophu. Lityebile kwimithombo yezimbiwa, igolide, amalahle kunye nezinye izixhobo, kodwa alinazo izixhobo zeoyile kunye negesi yendalo. Ngentsimbi ye-18:24 nge-6 kaFebruwari, ngexesha laseBeijing (nge-13:24 nge-6 kaFebruwari, ixesha lendawo), inyikima enkulu ye-7.8 yenzekile eTurkey, enobunzulu obuphambili beekhilomitha ezingama-20 kunye ne-epicenter kwi-38.00 degrees latitude emantla kunye ne-37.15 degrees longitude empuma.
