Kutshanje, imakethi ye-vinyl acetate yasekhaya inamava okunyuka kwamaxabiso, ngakumbi kwingingqi ye-East China, apho amaxabiso entengiso anyuke ukuya phezulu kwi-5600-5650 yuan/ton. Ukongezelela, abanye abarhwebi baye babona amaxabiso abo acatshulweyo eqhubeka nokunyuka ngenxa yokunqongophala, ukudala umoya oqinileyo wokuthengisa kwimarike. Le nto ayizenzekanga, kodwa isiphumo sezinto ezininzi ezidibeneyo kunye nokusebenza kunye.

Unikezelo ngecala lokucutha: isicwangciso sogcino kunye nolindelo lwemarike

Ukusuka kwicala lokubonelela, izicwangciso zokugcinwa kwamashishini amaninzi emveliso ye-vinyl acetate ibe yinto ebalulekileyo eqhuba ukunyuka kwamaxabiso. Ngokomzekelo, iinkampani ezifana noSeranis kunye noChuanwei baceba ukuqhuba ukugcinwa kwezixhobo ngoDisemba, okuya kunciphisa ngokuthe ngqo ukunikezelwa kweemarike. Kwangaxeshanye, nangona iBeijing Oriental iceba ukuphinda iqalise imveliso, iimveliso zayo zezokusetyenziswa buqu kwaye azinakuzalisa isithuba semarike. Ukongeza, ngokuqwalasela isiqalo sokuqala soMnyhadala weNtwasahlobo walo nyaka, imarike ngokubanzi ilindele ukuba ukusetyenziswa kweyoMnga kuya kuba phezulu kunakwiminyaka edlulileyo, oko kusenza mandundu ngakumbi imeko yokubonelela.

Ukukhula kwecala lemfuno: ukusetyenziswa okutsha kunye noxinzelelo lokuthenga

Kwicala lemfuno, imakethi esezantsi ye-vinyl acetate ibonisa ukukhula okuqinileyo. Ukuvela okuqhubekayo kokusetyenziswa okutsha kukhokelele ekwandeni koxinzelelo lokuthenga. Ingakumbi ukuphunyezwa kwezinye ii-odolo ezinkulu kuye kwaba nefuthe elibonakalayo eliphezulu kumaxabiso emarike. Nangona kunjalo, kubalulekile ukuqaphela ukuba iifektri ezincinci ze-terminal zinamandla alinganiselweyo okuthwala amaxabiso aphezulu, nto leyo inciphisa igumbi lokunyuka kwamaxabiso. Nangona kunjalo, indlela yokukhula iyonke yeemarike ezisezantsi zisabonelela ngenkxaso eyomeleleyo yokunyuka kwamaxabiso emarike ye-vinyl acetate.

Ixabiso lexabiso: Ukusebenza komthwalo ophantsi wamashishini endlela ye-carbide

Ukongeza kwizinto zokubonelela kunye nemfuno, izinto zeendleko zikwayenye yezizathu ezibalulekileyo zokuqhuba ixabiso le-vinyl acetate kwimarike. Umthwalo ophantsi wezixhobo zokuvelisa i-carbide ngenxa yemicimbi yeendleko uye wakhokelela amashishini amaninzi ukuba akhethe ukufumana i-vinyl acetate ngaphandle ukuvelisa iimveliso ezisezantsi ezifana ne-polyvinyl alcohol. Lo mkhwa awugcini nje ukwandisa imfuno yemarike ye-vinyl acetate, kodwa kwakhona uqhubela phambili iindleko zemveliso. Ngokukodwa kummandla osemntla-ntshona, ukuhla komthwalo wamashishini okucubungula i-carbide kuye kwakhokelela ekwandeni kwemibuzo yendawo kwiimarike, ngakumbi ukunyusa uxinzelelo lokunyuka kwexabiso.

Imbonakalo yeMarike kunye nemingcipheko

Kwixesha elizayo, ixabiso lemarike ye-vinyl acetate lisaza kujongana noxinzelelo oluthile oluphezulu. Ngakolunye uhlangothi, ukucutshungulwa kwecala lokubonelela kunye nokukhula kwecala lemfuno kuya kuqhubeka nokubonelela ngokunyuka kwexabiso; Ngakolunye uhlangothi, ukunyuka kwezinto zeendleko kuya kuba nefuthe elihle kumaxabiso emarike. Nangona kunjalo, abatyali-mali kunye nabasebenzi kufuneka baphaphe malunga nezinto ezinokuthi zibe yingozi. Umzekelo, ukuzaliswa kwempahla evela kumazwe angaphandle, ukuphunyezwa kwezicwangciso zogcino ngamashishini amakhulu emveliso, kunye nothethathethwano kwangethuba kunye neefektri ezisezantsi ezisekelwe ekunyukeni kolindelo kwimarike zonke zinokuba nempembelelo kumaxabiso emarike.
