Lub hom phiaj tseem ceeb
R - 22 raws li niaj hnub no siv ntau tshaj plaws hauv cov tub yees txias txias, feem ntau yog siv hauv tsev cua txias, ua lag luam cua txias, nruab nrab cua txias, mobile cua txias, cua kub twj tso kua mis dej rhaub, dehumidifier, khov hom tshuab ziab khaub ncaws, txias cia , khoom noj khoom haus tub yees, khoom siv tub yees, Marine industrial tub yees, lag luam tub yees, tub yees condensing units, supermarket zaub txee thiab lwm yam khoom siv tub yees. Difluorochloromethane tuaj yeem siv los ua cov khoom siv raw rau kev tsim cov polytetrafluoroethylene resins thiab ua ib qho nruab nrab ntawm cov hluav taws tua hluav taws 1121, nrog rau lub cev foaming tus neeg sawv cev rau polymers (yas).
Siv rau reciprocating compressors, ua refrigerant rau industrial, coj mus muag thiab domestic cua txias tshuab; Kuj tseem siv tau los ua tshuaj tua kab thiab tshuaj tsuag tshuaj tua kab mob aerosol, tuaj yeem siv los tsim cov tshuaj tua hluav taws; Nws yog cov khoom siv tseem ceeb rau kev tsim ntau yam fluorinated polymer tebchaw.
R22 yog HCFC refrigerant uas yuav raug txiav tawm los ntawm 2030 raws li Montreal Protocol.
Ib puag ncig kev hloov pauv tseem ceeb: R404A, R410A, R290, R23, R407C, R411A, R417A, R1270.
Cov tuam txhab tseem ceeb: cov tuam txhab tsim khoom hauv tsev yog quzhou Juhua Group, Shandong Dongyue Group, Zhejiang Meilan Tshuaj, sanaifu, thiab lwm yam.
Lub npe tseem ceeb thoob ntiaj teb: Dupont, Honeywell, Arkema thiab lwm yam. Txawm li cas los xij, raws li cov teb chaws tsim tau twb tshem tawm R22 ua ntej thiab tsis raug tso cai los tsim cov khoom no hauv lawv lub teb chaws, lub npe hu ua R22 uas tau muag hauv khw yog cov khoom siv hauv tsev OEM.
Feem ntau siv rau cov cua txias los yog ob lub tshuab overlapping qib, raws li lub siab kub kawg refrigerant, tub yees lub zog yog ntau dua li cov refrigerant.
R22 yog ib tug tswv cuab ntawm Freon tsev neeg ntawm hydrochlorofluorocarbons.
Freon txhais, freon yog saturated hydrocarbon (hydrocarbon) halogen derivatives ntawm lub npe dav, yog lub xyoo pua 30's nrog kev loj hlob ntawm kev lag luam tshuaj thiab ib chav kawm ntawm refrigerant, nws tshwm sim los daws cov tub yees cua txias sector rau refrigerant. Los ntawm cov ntsiab lus ntawm freon tuaj yeem pom, tam sim no cov neeg hais tias tsis yog-freon R134a, R410A thiab R407C yog tiag tiag freon.
Freon tuaj yeem rhuav tshem cov txheej txheej ozone vim tias muaj cov tshuaj chlorine (Cl) hauv cov tub yees, thiab nrog kev nce ntawm cov tshuaj chlorine atoms, cov txheej txheem ozone kev puas tsuaj muaj peev xwm nce ntxiv, nrog rau cov ntsiab lus hydrogen ntau ntxiv, ozone txheej puas muaj peev xwm txo qis. ; Cov nyhuv tsev xog paj feem ntau yog tshwm sim los ntawm qhov loj ntawm tsev cog khoom gases, xws li CO2, tsim nyob rau hauv cov txheej txheem ntawm qeeb oxidation thiab decomposition ntawm refrigerant.
