Ngokusetshenziswa kwenqubomgomo yaseShayina yokugcina nezindawo zokugcina izimpahla, izintengo zezinsimbi ezinkulu ezingenayo insimbi njenge-copper oxide, zinc, ne-aluminium nakanjani zizohlehla.Lo mkhuba ubonakale emakethe yamasheya ngenyanga edlule.Esikhathini esifushane, amanani entengo yempahla eningi asezinzile okungenani, futhi sisekhona indawo yokwehla okwengeziwe kwezintengo zemikhiqizo ezikhuphuke kakhulu esikhathini esidlule.Uma ubheka idiski ngesonto eledlule, intengo ye-rare earth praseodymium oxide iqhubekile nokukhula.Njengamanje, kungahlulelwa ngokuyisisekelo ukuthi intengo izoqina isikhashana ebangeni lama-yuan ayizigidi ezingama-500,000-53 ngethani ngalinye.Kunjalo, le ntengo iyintengo esohlwini lomkhiqizi kuphela kanye nokulungiswa okuthile emakethe yesikhathi esizayo.Akukho ukuguquguquka kwentengo okusobala kusukela kumsebenzi owenziwe ungaxhunyiwe ku-inthanethi.Ngaphezu kwalokho, ukusetshenziswa kwe-praseodymium oxide ngokwayo embonini ye-ceramic pigment kugxile kakhulu, futhi imithombo eminingi ikakhulukazi ivela esiFundazweni saseGanzhou naseSifundazweni saseJiangxi.Ngaphezu kwalokho, ukushoda kwe-zirconium silicate emakethe okubangelwa ukungezwani okuqhubekayo kwesihlabathi se-zircon kubonise umkhuba omubi.Kubandakanya iSifundazwe sasekhaya sase-Guangdong kanye neSifundazwe saseFujian abakhiqizi be-zirconium silicate baqinile njengamanje, futhi izingcaphuno nazo ziqaphe kakhulu, intengo yemikhiqizo ye-zirconium silicate engaba ngu-60 degrees cishe i-1,1000-13,000 yuan ngethani.Akukho ukushintshashintsha okusobala kwesidingo semakethe, futhi abakhiqizi namakhasimende banamandla ngentengo ye-zirconium silicate ngokuzayo.
Mayelana nokucwebezela, ngokuqedwa kancane kancane kwamathayili akhanyayo emakethe, izinkampani ze-melt block ezimelwe i-Zibo esifundazweni saseShandong zisheshisa ukuguqulwa kwazo ekupholiseni okucwebezelayo.Ngokwemininingwane ekhishwe yi-China Building and Sanitary Ceramics Association, ukukhishwa kwethayela le-ceramic kazwelonke ngo-2020 kweqe ama-square metres ayizigidi eziyizinkulungwane eziyi-10, lapho ukukhishwa kwamathayela acwebezelisiwe acwebezelisiwe kuzoba ngu-27.5% wengqikithi.Ngaphezu kwalokho, abanye abakhiqizi bebesashintsha imigqa yabo yokukhiqiza ekupheleni konyaka odlule.Uma kulinganiswa ngendlela efanele, ukukhishwa kwamathayela acwebezelisiwe ngo-2021 kuzoqhubeka nokuba cishe ku-2.75 billion square metres.Uma sibala inhlanganisela yeglaze ecwebezelayo kanye nokucwebezela okupholishiwe ndawonye, isidingo sikazwelonke se-glaze epholishiwe singamathani ayizigidi ezingu-2.75.Futhi i-glaze ephezulu kuphela edinga ukusebenzisa imikhiqizo ye-strontium carbonate, futhi i-glaze ephezulu izosebenzisa okungaphansi kwe-glaze epholishiwe.Ngisho noma ibalwa ngokwengxenye ye-glaze engaphezulu esetshenziselwa u-40%, uma u-30% wemikhiqizo ecwebezelayo ecwebezelayo isebenzisa ifomula yesakhiwo se-strontium carbonate.Isidingo sonyaka se-strontium carbonate embonini ye-ceramic silinganiselwa emathani angaba ngu-30,000 endaweni ecwebezelayo ecwebezelayo.Ngisho nokwengezwa kwenani elincane le-melt block, isidingo se-strontium carbonate kuyo yonke imakethe ye-ceramic yasekhaya kufanele ibe ngamathani angama-33,000.
Ngokolwazi olufanele lwemithombo yezindaba, njengamanje kunezindawo zezimayini ze-strontium ezingama-23 zezinhlobo ezahlukene eShayina, okuhlanganisa nezimayini ezinkulu ezi-4, izimayini ezimaphakathi ezi-2, izimayini ezincane ezi-5, nezimayini ezincane eziyi-12.Izimayini ze-strontium zaseShayina zigcwele izimayini ezincane nezimayini ezincane, kanti izimayini zasemalokishini nezizimele zithatha isikhundla esibalulekile.Kusukela ngoJanuwari-Okthoba 2020, ukuthunyelwa kweChina kwe-strontium carbonate kwaba amathani ayi-1,504, kanti ukuthengwa kwe-strontium carbonate yaseChina kusuka ngoJanuwari kuya ku-Okthoba 2020 kwaba amathani ayi-17,852.Izifunda ezihamba phambili zokuthekelisa ze-strontium carbonate yaseChina yiJapan, Vietnam, Russian Federation, Iran kanye neMyanmar.Imithombo eyinhloko yokungeniswa kwe-strontium carbonate yezwe lami iMexico, iJalimane, iJapane, i-Iran ne-Spain, kanti izimpahla ezivela kwamanye amazwe zingamathani angu-13,228, amathani angu-7236.1, amathani angu-469.6, namathani angu-42 ngokulandelana.Ngamathani ayi-12.Ngokombono wabakhiqizi abakhulu, embonini kasawoti yasekhaya yaseShayina, abakhiqizi bemikhiqizo ye-strontium carbonate bagxile eHebei, Jiangsu, Guizhou, Qinghai nakwezinye izifundazwe, futhi izinga labo lokuthuthuka likhulu kakhulu.Umthamo wamanje wokukhiqiza ungamathani angu-30,000/ngonyaka kanye ne-1.8 10,000 amathani/ngonyaka, amathani angu-30,000/ngonyaka, kanye namathani angu-20,000/ngonyaka, lezi zindawo zigxile kubahlinzeki bamanje ababaluleke kakhulu be-strontium carbonate baseChina.
Mayelana nezinto ezifunwa yimakethe, ukushoda kwe-strontium carbonate kuwukushoda kwesikhashana kwezimbiwa kanye nokuvikelwa kwemvelo.Kungabonwa kusengaphambili ukuthi ukunikezwa kwemakethe kufanele kubuyele kokujwayelekile ngemva kuka-Okthoba.Njengamanje, intengo ye-strontium carbonate emakethe ye-ceramic glaze iyaqhubeka nokwehla.Ikhotheshini isebangeni lentengo lika-16000-17000 yuan ngethani.Emakethe engaxhunyiwe ku-inthanethi, ngenxa yenani eliphezulu le-strontium carbonate, izinkampani eziningi sezivele ziyiyekile noma zithuthukise ifomula futhi azisasebenzisi i-strontium carbonate.Abanye abantu abachwepheshile abachwepheshile baphinde bethula ukuthi ifomula yokupholisha i-glaze ayisebenzisi ifomula yesakhiwo se-strontium carbonate.Isilinganiso sesakhiwo se-barium carbonate singabuye sihlangabezane nezidingo zobuchwepheshe zezinqubo ezisheshayo nezinye.Ngakho-ke, ngokombono wemakethe, kusengenzeka ukuthi intengo ye-strontium carbonate izobuyela emuva ebangeni le-13000-14000 ekupheleni konyaka.
