Amaxabiso entengiso yekhemikhali aqhubekile ukwehla malunga nesiqingatha sonyaka. Ukwehla okunjalo, ngelixa amaxabiso ooli ahlala ephezulu, ukhulele ekungalingani kwixabiso lezinto ezinxibelelana namakhamihemikhali. Ezona terminal zininzi kwikhonkrithi yeMizi-mveliso, kokukhona uxinzelelo kwiindleko zentshukumo yemveliso. Ke ngoko, iimveliso ezininzi zekhemikhali okwangoku zikwimeko ephezulu kodwa imakethi yabathengi eyingcayo, ebangelwa kuqoqosho lwemveliso embi kwiimveliso ezininzi zekhemikhali.
Ixabiso lentengiso le-vinyl acetate iphinde yaqhubeka nokwehla. Kwiminyaka yakutshanje, ixabiso lentengiso le-vinyl i-vinyl iwehlile ukusuka kwi-14862 yuan / ton ngoJuni 2022 ukuya kuJuni 2023 ukuya ku-Juni 2023 ukuya ku-Jun 2023, ngokuqhubekayo kwehla i-5990 yuan / ton. Ukusuka kwiindlela zexabiso kule minyaka imbalwa idlulileyo, owona maxabiso asezantsi embalini avele ngo-Epreli 2020, ixabiso eliphantsi lavela nge-20115 Yuan, kwaye elona xabiso liphezulu lavela ngo-16727 Yuan / Ton.

Nangona ixabiso le-vinyl i-vinyl inyibilikisele kunyaka olandelelekileyo, inzuzo yemveliso ye-vinyl acetate ihlala iphezulu kwaye uqoqosho lwemveliso ilungile. Kutheni le nto i-vanyl i-vinyl inokuthi ihlale ikhulile?
Iinkqubo ezahlukeneyo zemveliso ze-vinyl ye-vinyl ye-vinyl ye-vinyl yesiphumo senzuzo yokwahluka kunye nelahleko
Ngokutsho kotshintsho lwenqanaba lenzuzo ye-vinyl iveliswe yindlela ye-Ethylene, i-vinyl ye-vinyl iveliswe yi-Ethylene Indlela eveliswayo kwiminyaka embalwa edlulileyo, owona mgangatho uphezulu ufikelele kwi-50% okanye ngaphezulu, kwaye ireyithi yenzuzo iphakathi malunga ne-15%. Kungabonwa ukuba i-Ethylene esekwe kwi-vinyl ye-vinyl ye-vinyl ibe yimveliso enenzuzo kule minyaka mibini idlulileyo, ngokuchuma kakuhle kunye nenzuzo eninzi yenzuzo.

Ukusuka kwimbono yendlela ye-calcium carbide vinyl i-vinyl ye-vinyl acetate, kwiminyaka emibini edlulileyo, ngaphandle kwenzuzo ebalulekileyo ukusuka ngoMatshi 2022 ukuya kuJulayi 2022, onke amanye amaxesha ayekwimeko yokulahleka. Ukusukela nge-20 kaJuni 423, inqanaba le-Insorgin lendlela ye-calcium callide vinyl acetate yayijikeleze i-20% yelahleko yendlela ye-calcium ye-calcium vinyl i-vinyl i-0.2% ilahleko. Ingabonwa ukuba impumelelo yendlela ye-calcium ye-calcoum ye-vinyl acetate ihlwempu, kwaye imeko iyonke ibonisa ilahleko.

Ingabonwa ukuba ayisiyonto eqhelekileyo kwi-vinyl acetate ukuba kwinqanaba eliphezulu lenzuzo. Kuphela yindlela ye-ethyyy yemveliso ye-vinyl ye-vinyl ngoku isemoyeni enzuzo, ngelixa indlela ye-carbide ibisoloko ikwimeko yelahleko kule minyaka imbalwa idlulileyo.
Uhlalutyo lokugcina inzuzo ephezulu ye-vinyl ye-chanyl ye-vinyl ye-vinyl
1. Ixabiso leendleko ezikrokrelweyo ziyahluka kwiinkqubo ezahlukeneyo zemveliso. Kwimveliso ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl, ukusetyenziswa kweyunithi ye-ithoylene yi-0.35 kunye neyunithi yokutsalwa kwe-GACECATICATICATICATIC ACCIC yi-0.72. Ngokwenqanaba lamaxabiso aphakathi ngoJuni 2023, umda we-Ethylene esekwe kwimveliso ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl imalunga nama-37%, ngelixa i-acetic acid inama-45%. Ke ngoko, ukuguquguquka kwexabiso le-GLATICATICATICATIC enefuthe elikhulu kuguqulelo lweendleko lwe-vinyll ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl, elandelwa yi-Ethylene.
Ngokubhekisele kwindleko zendlela ye-calcoum ye-caljomide ye-vinyl acetate, i-calcium cartide malunga ne-47% yeendleko ze-calcoum ye-caljomis ye-vinyl ye-vinyl ye-vinyl ye-vinyl ye-calcium ye-calcium ye-calcelide ye-vinyl acetate. Ke ngoko, kwiNdawo yeCalcium carbide yeVinyl Acetate, utshintsho kwixabiso le-calcium carbide inegalelo elikhulu kwiindleko, ezohluke kakhulu kwifuthe le-Ethylene.
2. Ukuncipha okufanelekileyo kwi-Ethylene yeZinto ezingafunekiyo ze-Ecyylene kunye ne-GALCE I-ACCEC ikhokelele ekunciphiseni okubonakalayo kwiindleko. Ngokwedatha efanelekileyo, kunyaka ophelileyo, amaxabiso e-CFR mpuma empuma ye-Iathylene yehlile nge-33%, kwaye ixabiso le-aceccicl acid lehlile ngama-32%. Nangona kunjalo, iindleko zemveliso ze-vinyl acetate isebenzisa indlela ye-calcium carbide ikakhulu inqongophele ngexabiso le-calcium carbide. Kunyaka ophelileyo, ixabiso le-calcium carbide yehlile nge-25%.
Ke ngoko, kwimbono yeenkqubo ezimbini zemveliso ezahlukeneyo, iindleko ezingu-Dew zendlela ye-Icetl Icetate iye inciphile kakhulu, kwaye ukunciphisa iindleko kuyinto enkulu kunendlela ye-calcium caltide.

3. Nangona ixabiso le-vinyl ihlile, ukwehla akufuneki njengezinye iichemicals. Kunyaka ophelileyo, amaxabiso e-vinyl acetate ahlise nge-59%, ebonakala ngathi iyancipha, kodwa amaxabiso eekhemikhali anciphile nangakumbi.
I-Vinyl Acetate ihlala igcina umdaniso othile wenzuzo, ikakhulu ngenxa yokuncitshiswa kweendleko ezibangelwa kukuncipha kwamaxabiso ezilwanyana, endaweni yokuxhaswa kwemakethi yabathengi ngamaxabiso ayo. Le yimeko yangoku yokusulwa kwexabiso kwi-vinyl acetate yeshishini. Kwimeko yangoku yemakethi yamaTshayina kwixesha elifutshane, kunzima ukusingala ngokusisiseko ukutshintsha imeko ebuthathaka yemarike yemichiza yaseTshayina ngaphandle kwemigaqo-nkqubo yabathengi abathengi. Kulindelwe ukuba i-chain yexabiso le-vinyl acetate iya kuqhubeka nokugcina i-Logic yoTshintsho ephantsi, kwaye kulindeleke ukuba i-Polythyenene yentengiso yabathengi, ngakumbi i-Polythyenene kunye nemveliso ye-ED, iya kugcinwa ngokunciphisa i-vinyl i-acetate.
