Kuyo yonke imakethe ye-bisphenol A yalo nyaka, intengo ngokuyisisekelo iphansi kuno-10000 yuan (intengo yamathani, efanayo ngezansi), ehlukile esikhathini esikhazimulayo samayuan angaphezu kuka-20000 eminyakeni edlule. Umbhali ukholelwa ukuthi ukungalingani phakathi kokunikezwa kanye nesidingo kuvimbela imakethe, futhi imboni iya phambili ngaphansi kwengcindezi. Amanani angaphansi kuka-10000 yuan angase abe inkambiso emakethe ye-bisphenol A yesikhathi esizayo.
Ngokuqondile, okokuqala, amandla okukhiqiza i-bisphenol A akhule kakhulu. Kusukela ekuqaleni kwalo nyaka, amandla okukhiqiza i-bisphenol A aqhubekile nokukhishwa, nesamba sokukhiqiza saminyaka yonke samabhizinisi amabili sifinyelela kumathani angama-440000. Ethintwe yilokhu, umthamo wonyaka wokukhiqiza waseShayina we-bisphenol A ufinyelele amathani ayizigidi ezingu-4.265, ukwanda okungaba ngu-55% unyaka nonyaka, futhi isilinganiso sanyanga zonke sokukhiqiza sifinyelele amathani angu-288000, okubeka umlando omusha ophezulu. Esikhathini esizayo, ukunwetshwa kokukhiqizwa kwe-bisphenol A akumile, futhi kulindeleke ukuthi umthamo omusha wokukhiqiza we-bisphenol A uzodlula amathani ayizigidi ezingu-1.2 kulo nyaka. Uma kufakwa emkhiqizweni ngesikhathi, amandla okukhiqiza aminyaka yonke e-bisphenol A e-China azokhula afinyelele cishe kumathani ayizigidi ezi-5.5, okuwukukhula konyaka ngonyaka ngama-45%. Ngaleso sikhathi, ingozi yokwehla kwentengo ngaphansi kwama-yuan angu-9000 izoqhubeka nokuqoqwa.
Okwesibili, inzuzo yebhizinisi ayinalo ithemba. Kusukela ekuqaleni kwalo nyaka, ukuchuma kochungechunge lwezimboni ze-bisphenol A kuyehla. Ngokombono wezinto zokusetshenziswa ezikhuphukayo, Imakethe ye-phenolic ketone ihunyushwa ngokuthi “imakethe ye-phenolic ketone” M Umkhuba uwukuthi engxenyeni yokuqala, amabhizinisi e-phenolic ketone ayesesimweni sokulahlekelwa, futhi engxenyeni yesibili, amabhizinisi amaningi aphenduka. inzuzo enhle. Kodwa-ke, maphakathi noMeyi, imakethe ye-phenolic ketone yagqekeza indlela eyehlayo, lapho i-acetone yehla ngamayuan angaphezu kuka-1000 kanye ne-phenol yehla ngamayuan angaphezu kuka-600, okwenza ngokuqondile inzuzo ye-bisphenol a amabhizinisi. Kodwa-ke, noma kunjalo, i-bisphenol imboni isazungeza umugqa wezindleko. Njengamanje, idivayisi ye-bisphenol a iyaqhubeka nokugcinwa, futhi izinga lokusebenzisa amandla embonini lehlile. Isikhathi sokunakekela siphelile Ngemva komnqamulajuqu, kulindeleke ukuthi ukunikezwa okuphelele kwe-bisphenol A kuzokwanda, futhi ingcindezi yokuncintisana ingase iqhubeke ikhula ngaleso sikhathi. Umbono wenzuzo awukabi nawo ithemba.
Okwesithathu, ukusekelwa kwesidingo esibuthakathaka. Ukuqhuma komthamo wokukhiqiza we-bisphenol A kuhlulekile ukuhambisana nokukhula kwesidingo esiphansi komfula ngesikhathi, okuholele ekuphikisaneni okusobala kwesidingo sokuhlinzekwa kwempahla, okuyisici esibalulekile ekusebenzeni okuqhubekayo kwezinga eliphansi lemakethe. Ukusetshenziswa komfula we-polycarbonate (PC) bisphenol A ngaphezu kuka-60%. Kusukela ngo-2022, imboni ye-PC ingene emjikelezweni wokugaya umthamo wokukhiqiza isitoko, ngesidingo sokugcina siphansi kunokwenyuka kokuhlinzekwa. Ukungqubuzana phakathi kokunikezwa kanye nesidingo emakethe kusobala, futhi amanani e-PC ayaqhubeka nokwehla, okuthinta isasasa lamabhizinisi ukuqala ukwakha. Njengamanje, izinga lokusebenzisa umthamo wokukhiqiza we-PC lingaphansi kwama-70%, okunzima ukulithuthukisa esikhathini esifushane. Ngakolunye uhlangothi, nakuba umthamo wokukhiqiza i-epoxy resin engezansi uqhubeka nokukhula, isidingo semboni yokumboza i-terminal siyanethezeka, futhi kunzima ukuthuthukisa kakhulu ukusetshenziswa kwetheminali okufana nogesi, izinto zikagesi, nezinto eziyinhlanganisela. Izithiyo eziseceleni kwezidingo zisekhona, futhi izinga lokusebenzisa amandla embonini lingaphansi kwama-50%. Sekukonke, i-PC engezansi ne-epoxy resin ayikwazi ukusekela i-bisphenol A eluhlaza.
