Perchloroethylene: Kuchinja Kwegirini uye Maitiro Matsva eMusika we "Mambo weKuchenesa Dry"

Kubva pamasutu akarembera muzvitoro zvekuchenesa zvinhu zvakaoma mumakona emigwagwa kusvika kuzvikamu zvekuchenesa zvinhu zviri kucheneswa mumaworkshop ekugadzirisa mota, perchloroethylene, semushonga wehydrocarbon une chlorine unoshanda zvakanyanya, yave ichishandira maindasitiri zvakavimbika kweanoda kusvika zana remakore. Zvisinei, nekuwedzera kuri kuramba kuchiita mitemo yezvakatipoteredza pasi rose uye kukurumidza kusimudzira maindasitiri, kemikari iyi inozivikanwa se "Mambo weKuchenesa Zvinhu Zvisina Kunaka" ikozvino iri pamharadzano yekuchinja. Kunyange hazvo mashandisirwo ayo echinyakare achitarisana nematambudziko, mamakisi akawedzerwa anokosha akadai seperchloroethylene yemagetsi ari kuvhura nzvimbo itsva yekukura.

1. Pfupiso yeChigadzirwa: Chii chinonzi Perchloroethylene?

Perchloroethylene, inonziwo tetrachloroethylene, imusanganiswa weorganic une molecular formula C₂Cl₄ uye CAS Nhamba 127-18-4. Pasi pekupisa nekumanikidzwa kwakajairika, imvura isina ruvara, inoonekera, inoyerera yakasununguka ine hwema hwakaita seether uye haibati.

Zvimiro zveMuviri neMakemikoro

Perchloroethylene ine kugona kukuru kwekunyungudutsa uye kugadzikana kwakanyanya kwemakemikari. Inogona kunyungudutsa zvinhu zvakasiyana-siyana zvinosanganisira rabha, resin, mafuta, mafuta uye tar; maresini mazhinji ekugadzira anogona kunyungudika kana kuzvimba muperchloroethylene. Perchloroethylene yakachena inoramba yakasimba kunyangwe kana yapiswa kusvika 500℃ pasina mhepo, hunyoro uye catalysts. Kunyange zvakadaro, inogona kuoxidized pasi pemwaranzi ye ultraviolet kuti igadzire trichloroacetyl chloride uye huwandu hushoma hwe phosgene, saka huwandu hushoma hwe stabilizer hunowanzo kuwedzerwa kune zvigadzirwa zvemaindasitiri.

Perchloroethylene inoshandiswa zvakanyanya. Inonyanya kushandiswa se organic solvent, dry cleaning agent uye simbi degreasing solvent. Inoshandawo se anthelmintic drug, fat extractant, fire extinguisher uye smoke agent, uye inoshandiswa mukugadzirwa kwe trichloroethylene uye organic containing fluorine compounds.

2. Zvichangobva Kugadzirwa: Kugadziriswa Kwemitemo uye Kuchinja Kwemusika Kutsva

2.1 Musika Wepasi Pose: Kugadziriswa Kwemaumbirwo Pakati Pekukura Kwakagadzikana

Zvichienderana nedata razvino kubva kumasangano ekutsvagisa misika, saizi yemusika wepasi rose weperchloroethylene yakasvika pamadhora mabhiriyoni 1.93 muna 2025 uye inofungidzirwa kusvika mabhiriyoni 2.53 emadhora panosvika 2034, nekuwedzera kwegore negore (CAGR) kwe3.06% kubva muna 2026 kusvika 2034.

Musika weperchloroethylene uri kuchinja zvinoshamisa. Semusanganiswa unoshandiswa zvakanyanya une chlorine, unokosheswa zvikuru nekuda kwekugona kwawo kunyungudutsa mafuta uye wave chinhu chakakosha mumaindasitiri emachira nemotokari. Zvisinei, nekuda kwekunetseka kwezvakatipoteredza nehutano kunokonzerwa nekubuda kwayo kwemhepo inosvibisa (VOC), musika uri kutarisana nekuongororwa kwakasimba kwemitemo.

2.2 Kumanikidzwa Kwezvakatipoteredza: Kubva Panjodzi Dzehutano Kuenda Kumitemo Yakasimba

Njodzi dzehutano dzeperchloroethylene dzave kukwezva kutariswa kuri kukura. Yakarongwa neInternational Agency for Research on Cancer (IARC) seBoka rechipiri A rinokonzera kenza (zvichida rinokonzera kenza kuvanhu), perchloroethylene yakabatanidzwa muChinaRondedzero yeZvinhu Zvinosvibisa Mvura Zvine Chepfu Uye Zvinokuvadza (Chikamu Chekutanga)muna Chikunguru 2019.

Mitemo nemirau iri kuramba ichioma pasi rose iri kumanikidza vagadziri kugadzira dzimwe nzira dzakachengeteka uye kutungamira indasitiri iyi kubudiriro inoenderera mberi. Semuenzaniso, zvinonyungudutsa zvehydrocarbon uye matekinoroji ekutsiva carbon dioxide ari kusimudzirwa zvishoma nezvishoma muindasitiri yekuchenesa dry cleaning, zvichikonzera kudzikira kwekudiwa kweperchloroethylene muminda yechinyakare iri pasi pemvura. Kuwanda kwemhinduro dzekuchenesa dzinochengetedza nharaunda kwakanganisa zvakananga kudiwa kwemusika, sezvo kusimbiswa kuri kukura kwekuchengetedza nharaunda pakati pevatengi nemabhizinesi kuchikurumidzisa kutsvagisa nekugadzirwa kwezvinonyungudutsa zvakasiyana.

3. Mafambiro Eindasitiri: Shanduko Yepamusoro-soro uye Nzira Yekuvandudza Ruvara

3.1 Kuumbwa kweKudiwa Kwezvinhu Zvakasiyana-siyana: Kuderera Kwetsika vs Kuwedzera Kwemhando Yepamusoro

Indasitiri yeperchloroethylene inoratidza musiyano uri pachena wechimiro. Kune rumwe rutivi, ichikanganiswa nezvinoshandiswa panzvimbo dzekuchenesa zvakaoma, kudiwa kweperchloroethylene yemhando yeindasitiri kuri pasi pekumanikidzwa, nekushomeka kwegore negore kweinenge 2.1% mumakore anotevera. Kune rumwe rutivi, zvichikonzerwa nekuwanda kwekuda kwekugadzira semiconductor, musika weperchloroethylene yemhando yemagetsi uri kuwedzera paCAGR inosvika 12.5%.

Tichitora semuenzaniso kuChina, musika weperchloroethylene yemagetsi yakakwira kubva pasi pe5% kusvika pa22%. Vamwe vagadziri vemuno vanokwanisa kugadzira zvigadzirwa zvemagetsi zve5N-grade (99.999%), zvichibudirira kupinda muchikamu chekutengesa che semiconductor. Musika wezvigadzirwa zvemuno mu12-inch wafer fabs wakasvika 39% muna 2023.

Nzira iyi yekushandura yakafanana zvikuru neyeindasitiri yebutyl acetate mumakore achangopfuura: ese ari maviri anotarisana nekumanikidzwa kwakanyanya kwezvakatipoteredza, ese ari maviri anotsvaga kusimudzira kwepamusoro-soro uye kwakasarudzika, uye anotarisana nekuderera kwekudiwa mumisika yechinyakare nekuwedzera kukosha kwekuwedzera kwechigadzirwa.

3.2 Hupfumi Hwakatenderera: Kudzokorodza Kunova Chinhu Chitsva Chinosimudzira Kukura

Zvichitungamirirwa nemitemo nezvinodiwa nezvakatipoteredza, muenzaniso wehupfumi hweperchloroethylene wava kukura zvakanyanya. MuChina, huwandu hwezvinhu zvakadzokororwa zvakajairwa hwakasvika matani 31,000 muna 2023 nehuwandu hwe58.3%. Huwandu hwezvinhu zvakadzokororwa zvakashandiswa mukuchenesa kwakaoma, zvemagetsi uye zvemishonga hwakamira pa76.4% uye 35% zvichiteerana.

Pakazosvika gore ra2026, simba rekushandisa perchloroethylene pakudzokorodza rinotarisirwa kusvika matani 58,000, zvichiita 38% yehuwandu hwese hwezvinhu zviripo. Perchloroethylene inoshandiswazve inogona kuchengetedza kuchena kwayo pamusoro pe99.8% uye inogona kutsiva zvinhu zvisina kugadzirwa muzviitiko zvakawanda, zvichideredza mari yekugadzira uye kuderedza mutoro wezvakatipoteredza.

3.3 Kuchinja Kwezvipenyu: Kugadzira Tekinoroji Kunotungamira Remangwana

Vachitarisana nematambudziko ezvakatipoteredza, vagadziri veperchloroethylene vari kuwedzera mari yeR&D kuti vagadzire mhinduro dzinochengetedza nharaunda dzinosangana nezvinodiwa nemutemo. Kugadzira zvinhu zvine hungwaru uye matekinoroji ekugadzira zvinhu zvakasvibira zvakaita se electrocatalytic chlorination zvichave nzira huru dzekubudirira.

Inotungamirirwa nezvinangwa zvekabhoni mbiri, indasitiri yeperchloroethylene inotarisirwa kuzadzisa chinangwa chayo chehapana kukura kwesimba rekugadzira zvinhu zvisina kugadzirwa uye kufukidzwa kwakazara kwezvinodiwa zvitsva nezvigadzirwa zvakadzokororwagore ra2030 risati rasvika. Musika uchatevera nzira mbiri dzekuvandudza: kuchengetedza kushandiswa kwechinyakare kwakasimba uku uchitsvaga dzimwe nzira itsva uye dzinogara kwenguva refu dzinoenderana nezvinodiwa nevatengi uye mitemo yekutonga.

Kubva pakutanga kwegore ra2026, indasitiri yeperchloroethylene muChina yakagadzira nzvimbo yakasiyana-siyana yemakwikwi inotongwa nemakambani makuru e chlor-alkali akabatanidzwa uye ichiwedzerwa nevagadziri vemakemikari akanaka. CR5 (chiyero chehuwandu hwemakambani mashanu epamusoro) inosvika 68.5%. Mapurofiti ari kuramba achipatsanurwa: makambani ane kugona kwekuchenesa kwakachena, masisitimu ekudzokorodza akavharika uye manejimendi edhijitari anogona kuchengetedza purofiti yepamusoro pamusoro pe30%, nepo kugona kwepasi kunogona kurasikirwa.

4. Pfupiso uye Maonero

Mhedziso

Kubva kuzvitoro zvekuchenesa zvinhu zvisina tsvina kusvika kumafekitori ema semiconductor, perchloroethylene ine chinzvimbo chisingatsiviwi muindasitiri yemazuva ano nekuda kwekushanda kwayo kwakanaka mukunyungudika. Pakati penyika yose, indasitiri yeperchloroethylene iri padanho rekuchinja kukuru. Makambani anotungamira mukuputsa zvipingamupinyi zvehunyanzvi zvekuchenesa zvinhu zvine hutsanana hwakanyanya, kuvaka masisitimu ekudzokorodza zvinhu, uye kugamuchira hunyanzvi hwegirini achatora mikana yakanaka mukuchinja kunotevera kwemaindasitiri. Remangwana reperchloroethylene rinoenderana nekuti indasitiri iyi inowana sei chiyero chakakodzera pakati pezvinodiwa pakushanda uye mabasa ezvakatipoteredza - dambudziko rakajairika rinotarisana nechikamu chose chemakemikari akanaka.
