Global - Prime Tetrachloroethylene: Xigwitsirisi xa le ka tiindasitiri lexi nga lavekiki
Tinsimu Letikulu ta Xikombelo
Eka bindzu ra dry - cleaning, tetrachloroethylene yi yima tani hi gold - standard solvent. Ku olova ka yona ko hlawuleka handle ko endla matshalatshala ya tshoveka naswona yi susa nxaxamelo lowukulu wa swivati, kusuka eka mafurha yo nonoka eka malapi ya kahle kuya eka ti fibre leti nghenisiweke hi thyaka. Nhlayo ya yona yale henhla ya Kauri - Butanol (KB) yitiyisisa ku basisiwa loku heleleke, kasi profile ya yona ya chefu yale hansi swinene yinyika ndzhawu yo tirhela leyi hlayisekeke eka vafambisi. Tikhetane letikulu to basisa hi ku oma eAmerika N’walungu, Yuropa na Asia ti titshege hi tetrachlorethylene ya hina ku tisa mbuyelo lowu nga riki na xivati, ku hlayisa vutshembeki na ku languteka ka swiambalo swo olova.
Sekithara ya vumaki bya tinsimbi na yona yi vuyeriwa swinene eka tetrachloroethylene ya hina. Tanihi xitirhisiwa xo susa mafurha lexi tirhaka kahle, xi susa mafurha, switolwa ni swilo swin’wana leswi thyakeke hi ku hatlisa eka swilo leswi nga ehenhla ka nsimbi. Eka tifemeni to endla mimovha eJarimani na Japani, na switirhisiwa swa swihahampfhuka eUnited States, yi lulamisela tinsimbi eka maendlelo yo fana na ku penda, ku penda, na ku welda, ku tiyisisa ku namarhela ka le henhla na khwalithi ya swikumiwa. Hiku herisa masalela lawa yanga vangaka ku bola, swi engetela vutomi bya swiphemu swa nsimbi, leswi antswisaka ku tiya ka switirhisiwa swa makumu.
Eka ku endliwa ka tikhemikhali, tetrachloroethylene yi tirha tani hi xitirhisiwa xa nkoka xa le xikarhi. Xivumbeko xa yona xo hlawuleka xa timolekhuli xi pfumelela ku cinca-cinca ko tala, leswi endlaka leswaku ku endliwa tikhemikhali to hlawuleka, swigwitsirisi ni ti- polymer. Eka vumaki bya mirhi na electronics, yitirhisiwa ku tumbuluxa high - purity solvents eka maendlelo ya nkoka, ku tiyisisa ku kongoma na khwalithi ya switirhisiwa swohetelela. Xikombiso, eka vuhumelerisi bya tipulasitiki ta matirhelo yale henhla eka indasitiri ya elektroniki, ti compounds leti humaka eka tetrachloroethylene ti hoxa xandla eka matimba ya swiphemu xikan’we naku lwisana na kuhisa.
Tetrachloroethylene ya hina yitlhela yi tlanga xiave xa nkoka eka nxopaxopo wa mbango. Yi pfumeleriwile tani hi xisirhelelo xa ozone - swilo leswi herisaka, yitirhisiwa eka ku kamberiwa ka mati na misava ku humesa naku xopaxopa swilo leswi thyakeke leswi simekiweke eka oyili. Tilaboratori ta mbango emisaveni hinkwayo ti titshege hi yona ku kambela kahle swiyimo swa ku thyakisa, ku kongomisa matshalatshala yo lulamisa na ku tiyisisa ku landzeleriwa ka milawu.

Hi ku komisa
Yi pakiwile eka swibye swo hlawuleka, leswi nga vupfangiki, Global - Prime Tetrachlorethylene ya hina yi hlayisa ku tshamiseka ka yona hi nkarhi wa ku hlayisiwa na ku fambisiwa. Ntlawa wun’wana na wun’wana wu kamberiwa swinene ku vona ku basa, xivumbeko na matirhelo. Kunga khathariseki leswaku u le ka dry - cleaning, metalworking, vuhumelerisi bya tikhemikhali, kumbe nxopaxopo wa mbango, tetrachlorethylene ya hina yi nyika ku tshembheka na matirhelo lawa u ma lavaka ku humelela eka indasitiri ya wena.
