Kutshanje, imakethi ye-vinyl ye-vinyl ye-vinyl ye-vinyl iveze i-wave yexabiso, ngakumbi empuma yeMpuma China, apho amaxabiso entengiso aye anyuke ukuya kwi-5600-5650 yuan / ton. Ukongeza, abanye abarhwebi babone amaxabiso awo acatshuliweyo ayaqhubeka nokuphakama ngenxa yokunikezelwa okunqabileyo, ukudala imeko eqinileyo evenkileni kwimarike. Le phenomenon ayikho ngengozi, kodwa iziphumo ezininzi ezinxulumene nazo kwaye zisebenza kunye.

Ukukhutshwa kwecala

Ukusuka kwicala lokuhambisa, izicwangciso zesondlo ze-vinyl ye-vinyl ye-vinyl ye-vinyl ye-vinyl iyonyuso elibalulekileyo lokuqhuba. Umzekelo, iinkampani ezinje ngeSeranis kunye nesiCwangciso seChunjii ukwenza ulondolozo lwezixhobo ngoDisemba, oluya kuthi ngqo kunikezelwa ngokuthe ngqo. Kwangelo xesha, nangona iiCwangciso zeBeijing I-Orting Accovental yokuqalisa kwakhona, iimveliso zayo ikakhulu zisetyenziselwa wena kwaye azinakho ukugcwalisa isithuba sentengiso. Ukongeza, ukuthathela ingqalelo ekuqaleni komnyhadala wonyaka, imakethi ilindele ngokubanzi ukuba ukuselwa ngoDisemba kuya kuba ngaphezulu kweminyaka elidlulileyo, ukuqhubela phambili imeko eqinileyo.

Ukukhula kwecala le-Can: Ukusetyenziswa okutsha kunye nokuthenga uxinzelelo

Kwicala lemfuno, intengiso esezantsi ye-vinyl acetate ibonisa amandla omeleleyo akhulayo. Ukuvela okuqhubekayo kwendlela entsha yokusebenzisa kukhokelele ekwenzeni uxinzelelo lokuthenga. Ngokukodwa ukuphunyezwa kwemiyalelo emikhulu kunefuthe eliphezulu eliphezulu kumaxabiso entengiso. Nangona kunjalo, kufanelekile ukuba uqaphele ukuba iifenitshala ezincinci zesiphelo zinokwazi ukuvelisa amaxabiso aphezulu, ezinokuthi zenzeke kwinqanaba elithile kwigumbi lokwanda kwamaxabiso. Nangona kunjalo, ukukhula ngokupheleleyo kweemarike ze-dowstreamsream isazisela inkxaso eqinileyo kunyuso lwamaxabiso e-vinyl acette.

Ixabiso lexabiso: Ukusebenza okusezantsi kokusebenza kwe-carbide yendlela

Ukongeza kwizabelo kunye nezinto ezifunwa, izinto zexabiso zikwazezizathu ezibalulekileyo zokwenza ixabiso le-vinyl acetate emarikeni. Umthwalo ophantsi wezixhobo zemveliso ye-carbide ngenxa yemicimbi yeendleko ikhokelele kumashishini amaninzi ukukhetha ukuthuthwa kwe-vinyl acetate ngaphandle kwe-polyvinyl utywala. Le meko ingakonyusa kuphela imfuno yentengiso ye-vinyl acetate, kodwa iqhubela phambili kwiindleko zayo zemveliso. Ingakumbi kumda ntshona-ntshona, ukwehla komthwalo wamashishini okulungisa kwe-carbide kukhokelele kwiMibuzo yeSpoties kwintengiso, ngakumbi ukonyuka koxinzelelo lwamaxabiso.

Ukujonga intengiso kunye nengozi

Kwixesha elizayo, ixabiso lentengiso le-vinyl acetate izakujongana noxinzelelo oluthile. Kwelinye icala, ukuntywila kwecala lokuhambisa kunye nokukhula kwenqanaba lemfuno kuya kuqhubeka nokubonelela ngenkuthalo yokwanda kwamaxabiso; Kwelinye icala, ukwanda kwezinto zexabiso kuya kuba negalelo elifanelekileyo kumaxabiso entengiso. Nangona kunjalo, abatyali-mali kunye neengcali kufuneka baphaphile malunga nezinto ezinokubakho. Umzekelo, ukugcwalisa kwakhona kweempahla ezingeniswe elizweni, ukuphunyezwa kwezicwangciso zesondlo ngamashishini amakhulu okuvelisa imveliso, kunye nothethathethwano kwangoko kunye nemizi-mveliso esezantsi esekwe ekwenzeni izinto ezilindelekileyo kwimakethi
