Engxenyeni yokuqala yalo nyaka, imakethe ye-Foam ethambile yabonisa umkhuba wokunyuka kokuqala bese iwela isikhungo samanani esigcwele. Kodwa-ke, ngenxa yokuhlinzekelwa okuqinile kwe-EPDM eluhlaza ngoMashi kanye nokunyuka okunamandla ngamanani, amanani e-foam athambile aqhubeka nokukhuphuka, amanani entengo afinyelela ku-11300 yuan / ithoni engxenyeni yokuqala yonyaka, okulindelwe okweqile. Kusukela ngoJanuwari kuya kuJuni 2026, inani elijwayelekile le-foam elithambile emakethe yase-East China lalingu-9898.79 yuan / ton, ukwehla kwe-15.08% kuqhathaniswa nesikhathi esifanayo ngonyaka owedlule. Engxenyeni yokuqala yonyaka, intengo yemakethe ephansi ekuqaleni kukaJanuwari yayingu-8900 yuan, futhi umehluko wentengo phakathi kokuphakama okuphezulu kanye nethani eliphansi kwakungu-2600 yuan / ton, kancane kancane ukunciphisa ukuguquguquka kwemakethe.

Umkhuba ongezansi we-Market Price Center udalwa ukuhudula komkhuba ongezansi wezintengo ezibonakalayo ezibonakalayo, kanye nomphumela womdlalo phakathi kokuhlinzekwa kwamakethe okuningana kanye nesidingo esinamandla ". Engxenyeni yokuqala ka-2023, imakethe ye-bubble ethambile ingahlukaniswa ngokulinganayo ibe umthelela ophansi isigaba esiphakeme nesiteji sokushaqeka.
Kusukela ngoJanuwari kuya ekuqaleni kukaMashi, ukuguquguquka kwamanani kukhuphuka
1. I-EPDM eluhlaza iqhubeka nokukhuphuka. Ngesikhathi somkhosi waseSky Spring, ukulethwa kwezinto zokusetshenziswa ezivuthiwe zokuvikelwa kwemvelo kwakubushelelezi, futhi amanani aguqukayo futhi anda. Ekuqaleni kukaMashi, ngenxa yokunakekelwa kwezinto zokusetshenziswa eziluhlaza ezinjengesigaba sokuqala seHuanbing Zhenhai naseBinhua, ukunikezwa kwakuqinile, futhi amanani akhuphuka ngamandla, aqhuba i-foft foam ukuqhubeka nokukhuphuka. Engxenyeni yokuqala yonyaka, amanani akhuphuke.
2. Umthelela wezinto zenhlalo ukhubazeka kancane kancane, futhi imakethe ilindele ukululama kohlangothi lwesidingo. Abathengisi bazimisele ukusekela amanani entengo, kepha imakethe iyabuthwa ngomkhosi wentwasahlobo, futhi kunzima ukuthola ukunikezwa okunamanani aphansi emakethe ngemuva kweholide. Kulesi sigaba, ukufunwa phansi kwehlayo kuphansi, ukulondolozwa kwesidingo esiqinile sokuthengwa kwempahla, ikakhulukazi ukubuyela emakethe ngesikhathi somkhosi wentwasahlobo, ukuhudula phansi ngokwengqondo kwemakethe.
Kusuka maphakathi no-Mashi kuya kuJuni, ukuguquguquka kwamanani kuncishisiwe nokushintshashintsha kwemakethe kancane kancane
1 Kwikota yesibili, kancane kancane yathinta ukulethwa kwe-EPDM emakethe, okwenza intengo ye-EPDM yehle futhi ishayela intengo yemakethe ethambile ye-polythert ukwehla;
2 Kusukela ngoMeyi, kancane kancane kungenile ngesizini yendabuko yendabuko, kudonsela phansi isimo sengqondo se-Downstream. Imakethe ye-polythere ichichima kakhulu ekuhlinzekeni, kanye nokunikezwa kwemakethe kanye nokufunwa kuyaqhubeka ukuncintisana, okuholela ekwehleni okuqhubekayo ngamanani. Ama-warehouse amaningi aphansi agcwaliswa njengoba kudingeka. Lapho intengo ibuya iphuzu eliphansi, kuzoholela ekuthengeni okumaphakathi kwesidingo esiphansi, kepha kuzohlala isikhathi esingu-Nosuku ngosuku. Ekuqaleni kukaMeyi walesi sigaba, ngenxa yokushoda kokuhlinzekwa kwe-EPDM eluhlaza eluhlaza kanye nokunyuka kwamanani entengo, lapho imakethe ye-polythelekile ikhombisa ukuguquguquka kwamanani, ngamanani entengo elandela umkhondo .
Njengamanje, ama-polythease polyols asesesikhathini sokunwetshwa kwamandla. Njengengxenye yokuqala yonyaka, umthamo wonyaka wokukhiqiza wama-polytheate polyols eChina uye wakhulisa amathani ayizigidi ezingama-7.53. Ifektri igcina ukukhiqizwa okususelwa kwisu lokuthengisa, ngamafektri amakhulu ngokuvamile asebenza kahle, kuyilapho amafektri amancane naphakathi nendawo alungele. Izinga lokusebenza kwemboni liphakeme kancane kune-50%. Uma kuqhathaniswa nezidingo, ukuphathwa kwe-folf folether emakethe ye-polythert bekulokhu kuvame kakhulu. Ngokombono wesidingo esiphansi, njengoba ithonya lezici zenhlalo kancane kancane, abangena ngaphakathi kwemboni banethemba lokufunwa ngo-2023, kepha ukululama komkhiqizo wezimboni kulindelekile. Engxenyeni yokuqala yonyaka, imboni enkulu ye-Down Down Sponge yayinomugqa ophansi ngaphambi komkhosi wentwasahlobo, kanye nevolumu yokuthengwa kwempahla ngemuva kokuthola umkhosi wasentwasahlobo kunokuba bekulindelwe. Ngombhalo wokufunwa kusukela ngoMashi kuya ku-Ephreli, kanye nendabuko yesikhashana kusuka ngoMeyi kuya kuJuni. Ukuvuselelwa komkhakha weSponge engxenyeni yokuqala yonyaka bekuphansi kakhulu kunalokho obekulindelwe, kuhudula phansi isimo sokuthenga. Njengamanje, ngokunyuka nokuwa kwemakethe ethambile ye-bubble, okuthengwayo kakhulu kwe-downstream kuguqukele ekuthengeni okuqinile, ngomjikelezo wokuthengwa kwempahla eyodwa kuya kwamabili kanye nesikhathi sokuthengwa kwempahla yosuku ngosuku olulodwa. Izinguquko emijikelezweni yokuthengwa kweThengistream zinazo futhi ngezinga elithile ngokushintshashintshashintsha

Engxenyeni yesibili yonyaka, imakethe ye-folethert ethambile ingazwa ukwehla okuncane kanye namanani angabuya
Ekota yesine, isikhungo semakethe samandla adonsela phansi singaphinde siphinde sibe nobuthakathaka obuncane, njengoba imakethe iguquguquka kumdlalo ofunwa ngokuhlinzekwa ngemphumela wezemvelo wezinto zokusetshenziswa.
1. Ekupheleni kwendandatho yezinto ezibonakalayo eluhlaza C, amanye amandla amasha endandatho we-CRIRT C afakwa kancane kancane emakethe. Kusekhona amandla amasha okukhiqiza azokhishwa kwikota yesithathu. Kulindeleke ukuthi ukuhlinzekwa kwe-epitso eluhlaza eluhlaza kuzoqhubeka nokukhombisa umkhuba ongaphezulu kwikota yesithathu, futhi iphethini yokuncintisana izothuthuka ngokwengeziwe. Kungenzeka kube nomkhuba omncane ongezansi emakethe, futhi i-folther ethambile i-polyber ingahle ishaye phansi kancane lapho; Ngasikhathi sinye, ukwanda kokuhlinzekwa kwe-ePDM ebonakalayo eluhlaza kungathinta uhla lokushintshashintsha kwentengo. Kulindeleke ukuthi ukukhuphuka nokuwa kwemakethe ethambile ye-bubble kuzohlala kungakapheli 200-000 yuan / ton;
2. Ukunikezwa kwemakethe kwe-folther polyther kungenzeka kusenze silondoloze isimo esinele esidingakalayo. Engxenyeni yesibili yonyaka, amafektri amakhulu eShandong naseSouth China anezinhlelo zokugcina noma izinkathi zendawo zokuhlinzekwa okuqinile emakethe ye-polyther, edonsa ukwanda okuhle emakethe. Ukusakazwa kwezimpahla eziphakathi kwezifunda kungenzeka kulindeleke ukubaqinisa;
3 Umsebenzi wokuhweba kanye nokusimama kwemakethe ye-polyther kulindeleke ukuthi kube ngcono kancane kancane. Ngokusho kwemboni inertia, izinkampani eziningi ezaphansi zaphansi zithenga izinto ezingavuthiwe ngaphambi kwesikhathi esiphezulu lapho amanani entengo elungele ikota yesithathu. Ukukhokhelwa kwemakethe kwikota yesithathu kulindeleke ukuthi kuthuthuke ngokuqhathaniswa nekota yesibili;
4. Kusukela ekuhlaziyweni kwesizini kwe-folthelekile ethambile, eminyakeni eyishumi edlule, imakethe ye-foam ethambile iye yabhekana nokwanda okukhulu kusuka ngo-July kuya ku-Okthoba, ikakhulukazi ngoSepthemba. Njengoba kancane kancane imakethe ingena kancane kancane "i-Golden Nine Silver Ten" isidingo se-Ten "selifunwa isizayo, kulindeleke ukuthi ukuthengiselana kwemakethe kuzoqhubeka nokwenza ngcono. Kwikota yesine, izimboni zezimoto ne-sponge kulindeleke ukuthi zibone ukwanda kokukhula kwe-oda, kwakha ukusekelwa ohlangothini lwesidingo. Ngokwanda okuqhubekayo endaweni egcwalisiwe yezindawo ezithengiswayo kanye nokukhiqizwa komkhakha wezimoto, kungahle kube ngezinga elithile lesidingo semakethe se-foleam ethambile.

Ngokusekelwe ekuhlaziyweni okungenhla, kulindeleke ukuthi imakethe ye-Foam ethambile ye-Foam iyophinda iphinde ifinyelele phansi ngemuva kwengxenye yesibili yonyaka, kepha ngenxa yezikhathi ezithile, kuzoba nomkhuba wokulungiswa ekupheleni konyaka. Ngaphezu kwalokho, umkhawulo ophezulu wokuvuselelwa kwemakethe yokuqala ngeke abe phezulu kakhulu, futhi uhla lwamanani entengo evamile kungenzeka lube phakathi kuka-9400-10500 yuan / ton. Ngokusho kwamaphethini wesikhathi sonyaka, iphuzu eliphakeme engxenyeni yesibili lonyaka kungenzeka livele ngoSepthemba nango-Okthoba, kuyilapho iphuzu eliphansi lingavela ngoJulayi nakuDisemba.
