I-Perchloroethylene: Ukuguqulwa Okuluhlaza kanye Nephethini Elisha Lemakethe “Yenkosi Yokuhlanza Okungadingi Ugesi”

Kusukela kumasudi alenga ezitolo zokuhlanza ezomile ezisekhoneni lomgwaqo kuya ezingxenyeni eziqondile ezihlanzwa ezindaweni zokulungisa izimoto, i-perchloroethylene, njengesinyibilikisi se-hydrocarbon esine-chlorine esebenza kahle kakhulu, isisebenzele imikhakha yezimboni ngokwethembeka cishe iminyaka eyikhulu. Kodwa-ke, ngemithethonqubo yezemvelo yomhlaba wonke eqinile kanye nokuthuthukiswa kwezimboni okusheshayo, leli khemikhali elaziwa ngokuthi “iNkosi Yokuhlanza Okomile” manje lisesigcawini soguquko. Ngenkathi ukusetshenziswa kwalo kwendabuko kubhekene nezinselele, amazinga anenani eliphezulu njenge-perchloroethylene ye-elekthronikhi avula isikhala esisha sokukhula.

1. Ukubuka Konke Komkhiqizo: Kuyini i-Perchloroethylene?

I-Perchloroethylene, ebizwa nangokuthi i-tetrachloroethylene, iyinhlanganisela yezinto eziphilayo enefomula yama-molecule i-C₂Cl₄ kanye ne-CAS No. 127-18-4. Ngaphansi kokushisa okuvamile kanye nengcindezi, iwuketshezi olungenambala, olusobala, olugeleza ngokukhululeka olunephunga elifana ne-ether futhi alushisi.

Izakhiwo Zomzimba Nezamakhemikhali

I-Perchloroethylene inezinga eliphezulu lokuncibilika kanye nokuqina okuphezulu kwamakhemikhali. Ingancibilikisa izinto eziningi ezihlanganisa irabha, i-resin, amafutha, uwoyela kanye ne-tar; iningi lama-resin okwenziwa ayancibilika noma ayavuvukala ku-perchloroethylene. I-perchloroethylene emsulwa ihlala izinzile ngisho noma ishiswa ku-500℃ uma kungekho moya, umswakama kanye nama-catalyst. Noma kunjalo, ingase i-oxidized ngaphansi kwemisebe ye-ultraviolet ukuze yakhe i-trichloroacetyl chloride kanye nenani elincane le-phosgene, ngakho-ke inani elincane le-stabilizer livame ukungezwa emikhiqizweni yezinga lezimboni.

I-Perchloroethylene inezinhlelo zokusebenza eziningi. Isetshenziswa kakhulu njengesithako esiphilayo, isithako sokuhlanza okomile kanye nesithako esisusa amafutha ensimbi. Iphinde isebenze njengesidakamizwa esilwa namagciwane, isithako esikhipha amafutha, isithako sokucisha umlilo kanye nesithako somusi, futhi isetshenziswa ekwakhiweni kwamakhemikhali e-trichlorethylene kanye ne-fluorine aqukethe i-organic.

2. Izibuyekezo Zakamuva: Ukulungiswa Kwenqubomgomo kanye Nokuguquguquka Kwemakethe Okusha

2.1 Imakethe Yomhlaba Wonke: Ukulungiswa Kwesakhiwo Phakathi Kokukhula Okuzinzile

Ngokusho kwedatha yakamuva evela ezikhungweni zocwaningo lwemakethe, usayizi wemakethe yomhlaba wonke we-perchloroethylene ufinyelele cishe ku-USD 1.93 billion ngo-2025 futhi kulindeleke ukuthi ufinyelele ku-USD 2.53 billion ngo-2034, ngesilinganiso sokukhula sonyaka esihlanganisiwe (CAGR) esingu-3.06% kusukela ngo-2026 kuya ku-2034.

Imakethe ye-perchloroethylene ibhekana nezinguquko eziphawulekayo. Njenge-solvent esetshenziswa kabanzi ene-chlorine, iyaziswa kakhulu ngenxa yamandla ayo aqinile okuncibilikisa uwoyela futhi isibe yinto eluhlaza ebaluleke kakhulu embonini yezindwangu nezimoto. Kodwa-ke, ngenxa yokukhathazeka ngezemvelo nezempilo okubangelwa ukukhishwa kwayo kwe-volatious organic compound (VOC), imakethe ibhekene nokuhlolwa okunzima kwemithetho.

2.2 Ingcindezi Yemvelo: Kusukela Ezingozini Zempilo Kuya Emithethweni Eqinile

Izingozi zempilo ze-perchloroethylene zidonsele ukunaka okwandayo. Kuhlukaniswe yi-International Agency for Research on Cancer (IARC) njenge-I-carcinogen yeqembu 2A (mhlawumbe ibangela umdlavuza kubantu), i-perchloroethylene yafakwa eShayinaUhlu Lwezinto Ezingcolisa Amanzi Ezinobuthi Neziyingozi (Iqembu Lokuqala)ngoJulayi 2019.

Imithetho nemigomo eqinile emhlabeni wonke iphoqa abakhiqizi ukuthi bathuthukise ezinye izindlela eziphephile futhi baqhubekisele phambili imboni ekuthuthukisweni okusimeme. Isibonelo, izinyibilikisi ze-hydrocarbon kanye nobuchwepheshe bokufaka esikhundleni se-carbon dioxide obuwuketshezi bukhuthazwa kancane kancane embonini yokuhlanza okomile, okuholela ekunciphiseni isidingo se-perchloroethylene emasimini endabuko angezansi komfula. Ukuthandwa okwandayo kwezixazululo zokuhlanza ezinobungani nemvelo kuthinte ngqo isidingo semakethe, njengoba ukugcizelela okukhula ekusimeme phakathi kwabathengi namabhizinisi kusheshisa ucwaningo kanye nentuthuko yezinyibilikisi ezihlukile.

3. Izitayela Zemboni: Uguquko Olusezingeni Eliphezulu kanye Nomzila Wokuthuthukiswa Okuluhlaza

3.1 Isakhiwo Sesidingo Esihlukahlukene: Ukuncipha Kwendabuko vs Ukwanda Okuphezulu

Imboni ye-perchloroethylene ikhombisa umehluko ocacile wesakhiwo. Ngakolunye uhlangothi, ethintwa yizinto ezithatha indawo emkhakheni wokuhlanza okomile, isidingo se-perchloroethylene yezinga lezimboni esivamile singaphansi kwengcindezi, kanti isilinganiso sonyaka sokwehla cishe ngo-2.1% eminyakeni ezayo. Ngakolunye uhlangothi, ngenxa yesidingo esikhulayo ekukhiqizweni kwe-semiconductor, imakethe ye-perchloroethylene yezinga le-elekthronikhi iyanda ku-CAGR ecishe ibe ngu-12.5%.

Uma sithatha iShayina njengesibonelo, isabelo semakethe se-perchloroethylene ye-elekthronikhi ehlanzekile kakhulu sikhuphuke sisuka ngaphansi kuka-5% saya ku-22%. Abanye abakhiqizi basekhaya bayakwazi ukukhiqiza imikhiqizo ye-elekthronikhi ye-5N (99.999%), bangene ngempumelelo kuchungechunge lokuphakelwa kwe-semiconductor. Isabelo semakethe semikhiqizo yasekhaya ku-wafer fabs engu-12-intshi sifinyelele ku-39% ngo-2023.

Le ndlela yokuguqula ifana kakhulu neyemboni ye-butyl acetate eminyakeni yamuva nje: zombili zibhekene nengcindezi enkulu yemvelo, zombili ziphishekela ukuthuthukiswa okuphezulu nokukhethekile, futhi zibhekana nesidingo esinciphayo ezimakethe zendabuko ngokwandisa inani elengeziwe lomkhiqizo.

3.2 Umnotho Ojikelezayo: Ukuvuselela Ukusetshenziswa Kabusha Kuba Yindlela Entsha Yokukhula

Iqhutshwa yizinqubomgomo kanye nezidingo zemvelo, imodeli yomnotho ojikelezayo we-perchloroethylene isivuthiwe kakhulu. E-China, inani elijwayelekile lokuvuselela kabusha lifinyelele kumathani angu-31,000 ngo-2023 ngesilinganiso sokuvuselela kabusha esingu-58.3%. Izinga lokungena kwemikhiqizo evuselelwe kabusha emikhakheni yokuhlanza eyomile, ye-elekthronikhi neyemithi limi ku-76.4% kanye no-35% ngokulandelana.

Ngo-2026, amandla okusebenzisa kabusha i-perchloroethylene kulindeleke ukuthi afinyelele amathani angu-58,000, okubalwa u-38% wenani lonke lokunikezwa. I-perchloroethylene ephinde yasetshenziswa ingagcina ubumsulwa obungaphezu kuka-99.8% futhi ingathatha indawo yezinto ezingakasetshenziswa ezimweni eziningi zokusetshenziswa, inciphise ngempumelelo izindleko zokukhiqiza futhi inciphise umthwalo wemvelo.

3.3 Ukuguqulwa Okuluhlaza: Ukusungula Izinto Ezintsha Kwezobuchwepheshe Kuholela Ekusasa

Bebhekene nezithiyo zemvelo, abakhiqizi be-perchloroethylene bandisa ukutshalwa kwezimali kwe-R&D ukuze bathuthukise izixazululo ezinobungani nemvelo ezihlangabezana nezindinganiso zokusebenza kanye nezidingo zomthetho. Ukukhiqiza okuhlakaniphile kanye nobuchwepheshe bokwenziwa okuluhlaza njenge-electrocatalytic chlorination kuzoba yizinkomba ezibalulekile zentuthuko.

Iqondiswa yimigomo ye-dual-carbon, imboni ye-perchloroethylene kulindeleke ukuthi ifinyelele umgomo ohlukaniswe ngezigaba we-ukukhula okungekho emkhiqizweni ongakaze ubonwe kanye nokumbozwa okugcwele kwesidingo esisha semikhiqizo ephinde yasetshenziswangaphambi kuka-2030. Imakethe izolandela umkhuba wokuthuthukiswa okubili: ukugcina ukusetshenziswa kwendabuko okuzinzile ngenkathi ihlola ezinye izindlela ezintsha nezisimeme ezivumelana nezintandokazi zabathengi ezishintshashintshayo kanye nemithetho yokulawula.

Kusukela ekuqaleni kuka-2026, imboni ye-perchloroethylene yaseShayina yakhe indawo yokuncintisana ehlukahlukene ephethwe amabhizinisi amakhulu e-chlor-alkali ahlanganisiwe futhi esekelwa abakhiqizi bamakhemikhali abangochwepheshe. I-CR5 yemboni (isilinganiso sokuhlushwa kwamabhizinisi amahlanu aphezulu) ifinyelela ku-68.5%. Inzuzo iyanda ngokwahlukana: amabhizinisi anekhono lokuhlanza ubumsulwa obuphezulu, izinhlelo zokuvuselela kabusha ezivaliwe kanye nokuphathwa kwedijithali angagcina inzuzo enkulu ngaphezu kuka-30%, kuyilapho amandla aphansi angase alahlekelwe.

4. Isifinyezo kanye Nombono

Isiphetho

Kusukela ezitolo zokuhlanza izimpahla ezomile kuya ezimbonini ze-semiconductor, i-perchloroethylene ithatha isikhundla esingenakufakwa esikhundleni embonini yesimanje ngenxa yokusebenza kwayo okuvelele kokuncibilika. Phakathi komkhankaso womhlaba wonke wokuvikela imvelo, imboni ye-perchloroethylene imi endaweni ebalulekile yokuguquka. Amabhizinisi ahola ekuqedeni izithiyo zobuchwepheshe zokuhlanzwa okuhlanzekile okuphezulu, ukwakha izinhlelo zokuvuselela kabusha ezivaliwe, kanye nokwamukela ukusungula izinto ezintsha eziluhlaza azosebenzisa amathuba amahle ekushintsheni okulandelayo kwezimboni. Ikusasa le-perchloroethylene lincike ekutheni imboni ithola kanjani ibhalansi efanele phakathi kwezidingo zokusebenza kanye nemithwalo yemfanelo yezemvelo - inselele evamile ebhekene nayo yonke imboni yamakhemikhali amahle.
