Injani imeko yemarike yasekhaya neyangaphandle ye-non-ionic cellulose ether?

(1)Isishwankathelo semarike ye-nonionic cellulose ether yehlabathi:

Ngokwembono yokusasazwa kwamandla emveliso yehlabathi, ama-43% ewonke jikelelei-cellulose etherukuveliswa ngo-2018 kwavela e-Asia (i-China yayibalelwa kwi-79% yemveliso yase-Asia), iNtshona Yurophu yabalelwa kwi-36%, kunye neNyakatho Melika i-8%. Ukusuka kumbono wemfuno ye-cellulose ether yehlabathi, ukusetyenziswa kwe-cellulose ether emhlabeni jikelele kwi-2018 malunga ne-1.1 yezigidi zeetoni. Ukususela kwi-2018 ukuya kwi-2023, ukusetyenziswa kwe-cellulose ether kuya kukhula kumyinge wonyaka we-2.9%.

Phantse isiqingatha sokusetyenziswa kwe-cellulose ether yehlabathi iyonke i-ionic cellulose (emelwe yi-CMC), esetyenziswa kakhulu kwi-detergents, i-oilfield additives kunye nezongezo zokutya; malunga nesinye kwisithathu yi-non-ionic methyl cellulose kunye nezinto eziphuma kuyo (emelwe nguHPMC), kunye nesithandathu esiseleyo yi-hydroxyethyl cellulose kunye ne-derivatives kunye nezinye ii-cellulose ethers. Ukukhula kwemfuno ye-non-ionic cellulose ethers iqhutywa ikakhulu zizicelo kwimimandla yezixhobo zokwakha, iingubo, ukutya, amayeza, kunye neekhemikhali zemihla ngemihla. Ngokwembono yokusasazwa kwengingqi kwimarike yabathengi, imakethi yaseAsia yeyona marike ikhula ngokukhawuleza. Ukusukela ngo-2014 ukuya ku-2019, isantya sokukhula sonyaka esihlanganisiweyo semfuno ye-cellulose ether e-Asia ifikelele kwi-8.24%. Phakathi kwazo, eyona mfuno iphambili e-Asiya ivela e-China, ibala i-23% yemfuno yehlabathi jikelele.

(2)Ushwankathelo lwemarike yasekhaya engeyiyo ionic cellulose ether:

E-China, ionic cellulose ethers emelwe yiCMCiphuhliswe ngaphambili, isenza inkqubo yemveliso esele ivuthiwe kunye nomthamo omkhulu wemveliso. Ngokwedatha ye-IHS, abavelisi baseTshayina bathathe phantse isiqingatha somthamo wemveliso yehlabathi yeemveliso ezisisiseko ze-CMC. Uphuhliso lwe-non-ionic cellulose ether luqale kade kwilizwe lam, kodwa isantya sophuhliso siyakhawuleza.

Ngokwedatha ye-China Cellulose Industry Association, umthamo wemveliso, imveliso kunye nokuthengiswa kwe-non-ionic cellulose ethers yamashishini asekhaya e-China ukusuka ngo-2019 ukuya ku-2021 ngolu hlobo lulandelayo:

Emva kweminyaka yophuhliso, imakethi yaseTshayina ye-non-ionic cellulose ether yenze inkqubela enkulu. Ngo-2021, umthamo owenziweyo wemveliso yezinto zokwakha-ibakala le-HPMC liya kufikelela kwiitoni ze-117,600, imveliso iya kuba yi-104.300 yeetoni, kwaye umthamo wokuthengisa uya kuba neetoni ezingama-97,500. Izinga elikhulu lemizi-mveliso kunye neenzuzo zasekhaya ziye zafikelela endaweni yasekhaya. Nangona kunjalo, kwiimveliso ze-HEC, ngenxa yokuqalisa kade kwe-R&D kunye nemveliso kwilizwe lam, inkqubo yemveliso entsonkothileyo kunye nemiqobo ephezulu yobugcisa, umthamo wangoku wemveliso, imveliso kunye nomthamo wentengiso yeemveliso zasekhaya zeHEC zincinci. Nangona kunjalo, kwiminyaka yakutshanje, njengoko amashishini asekhaya eqhubeka nokwandisa utyalo-mali kuphando kunye nophuhliso, ukuphucula inqanaba lethekhnoloji kunye nokuphuhlisa ngokusebenzayo abathengi abasezantsi, imveliso kunye nokuthengisa kuye kwanda ngokukhawuleza. Ngokutsho kwedatha evela kwi-China Cellulose Industry Association, ngo-2021, amashishini amakhulu asekhaya i-HEC (ebandakanyiweyo kwizibalo zombutho woshishino, yonke injongo) inomthamo owenziweyo wemveliso yeetoni ezili-19,000, imveliso yeetoni ezingama-17,300, kunye nomthamo wokuthengisa we-16,800 yeetoni. Phakathi kwabo, amandla okuvelisa anyuke ngo-72.73% ngonyaka xa kuthelekiswa no-2020, imveliso yanda ngo-43.41% ngonyaka, kwaye umthamo wokuthengisa unyuke nge-40.60% ngonyaka.

Njengokongeza, umthamo wokuthengisa we-HEC uchatshazelwa kakhulu yimfuno yemarike esezantsi. Njengeyona ndawo ibaluleke kakhulu yesicelo se-HEC, imboni yokwambatha inobudlelwane obuqinileyo kunye neshishini le-HEC ngokwemveliso kunye nokuhanjiswa kweemarike. Ukusuka kwimbono yokusasazwa kweemarike, imarike yorhwebo yokugquma isasazwa ikakhulu eJiangsu, eZhejiang naseShanghai eMpuma China, eGuangdong eMzantsi China, kunxweme olukumazantsi mpuma, naseSichuan kuMazantsi-ntshona eTshayina. Phakathi kwabo, imveliso yokugquma eJiangsu, Zhejiang, Shanghai naseFujian ibalelwa malunga ne-32%, kwaye eMzantsi China naseGuangdong babalelwa malunga ne-20%. 5 ngasentla. Imarike yeemveliso zeHEC igxile kakhulu eJiangsu, Zhejiang, Shanghai, Guangdong naseFujian. I-HEC okwangoku isetyenziswa kakhulu kwiingubo zokwakha, kodwa ifanelekile kuzo zonke iintlobo zeengubo ezisekelwe emanzini ngokweempawu zayo zemveliso.

Ngo-2021, isiphumo sonyaka se-coatings yase-China kulindeleke ukuba sibe malunga ne-25.82 yezigidi zeetoni, kwaye imveliso ye-architectural coatings kunye ne-industry yemizi-mveliso iya kuba yi-7.51 yezigidi zeetoni kunye ne-18.31 yezigidi zeetoni ngokulandelelana. Iingubo ezenziwe ngamanzi ngoku zimalunga ne-90% yeeteyiphu zokwakha, kwaye malunga ne-25%, kuqikelelwa ukuba imveliso yepeyinti esekelwe emanzini kwilizwe lam ngo-2021 iya kuba malunga ne-11.3365 yezigidi zeetoni. Ngokwethiyori, inani le-HEC elongezelelweyo kwiipeyinti ezisekelwe kumanzi yi-0.1% ukuya kwi-0.5%, ibalwa kumyinge we-0.3%, icinga ukuba zonke iipeyinti ezisekelwe emanzini zisebenzisa i-HEC njengesongezo, imfuno yesizwe ye-HEC ye-paint-grade imalunga neetoni ezingama-34,000. Ngokusekwe kwimveliso yokugquma yehlabathi iyonke ye-97.6 yezigidi zeetoni ngo-2020 (apho i-architectural coatings ithatha i-58.20% kunye ne-industrial coatings akhawunti ye-41.80%), imfuno yehlabathi yokugquma ibakala le-HEC iqikelelwa malunga ne-184,000 yeetoni.

Ukushwankathela, okwangoku, isabelo semarike yebakala lokugquma i-HEC yabavelisi basekhaya e-China sisaphantsi, kwaye isabelo semarike yasekhaya sihlala ikakhulu ngabavelisi bamazwe ngamazwe abamelwe yi-Ashland yase-United States, kwaye kukho indawo enkulu yokutshintshwa kwasekhaya. Ngokuphuculwa komgangatho wemveliso ye-HEC yasekhaya kunye nokwandiswa komthamo wemveliso, iya kukhuphisana ngakumbi nabavelisi bamazwe ngamazwe kumhlaba osezantsi omelwe ziingubo. Ukutshintshwa kwekhaya kunye nokhuphiswano lwemarike yamazwe ngamazwe luya kuba yeyona ndlela yophuhliso yolu shishino kwixesha elithile kwixesha elizayo.
