Ukutyhila iiMfihlo eziNgachazwanga ze-perchlorethylene: Ukuphucula ulwazi lweMveliso

Malunga:

Perchlorethylene, kwaziwa njengetetrachlorethylene, i-organic compound kunye ne-formula C2Cl4 kwaye ilulwelo olungenambala. Kuye kwaba yinto ephambili kwiinkqubo ezahlukeneyo zoshishino kunye nokusetyenziswa. Ngaphandle kokubaluleka kwayo, kukho ukunqongophala kolwazi malunga nale nto ininzi. Ke ngoko, ukucacisa i-perchlorethylene, ukuhlalutya iipropathi zayo, ukuphonononga ukusetyenziswa kwayo, kunye nokuqonda ukhuseleko lwayo kuye kwabaluleka. Ngophando olunzulu lwale miba, eli phepha lijolise ekunikeni abafundi ulwazi olubanzi lwe-perchlorethylene.

Iimpawu zeperchlorethylene:

I-Perchlorethylene lulwelo olungatshayo olungenambala olubonisa incasa emnandi kwiindawo eziphezulu. Ifomula yemolekyuli yiC2Cl4 kwaye iqulethe iiathom zekhabhoni ezimbini kunye neeathom zeklorini ezine. Inozinzo olubalaseleyo, ukungasabelani nezinto ezininzi, kunye nomthamo ophezulu wokunyibilikisa.

Ukusetyenziswa kwe-perchlorethylene:

1. Ukucoca okomileyo: Esinye sezicelo ezidumileyo ze-perchlorethylene kumashishini okucoca okomileyo. Ukungatsha kwayo, ukunyibilika okuphezulu kunye neqondo eliphantsi lokubilisa liyenza ibe sisinyibilikisi esifanelekileyo sokususa amabala kunye nokungcola kwiilaphu. Ikhono le-perc lokunyibilikisa i-oyile kunye ne-organic compounds liqinisekisa ukucoca okusebenzayo ngaphandle kokonakalisa izinto ezibuthathaka.

2. I-Metal degreasing: Iimpawu ezinamandla zokunciphisa i-perchlorethylene nazo zifanelekile kwi-industry processing industry. Ngokuqhelekileyo isetyenziselwa ukususa igrisi, i-oyile, kunye nongcoliseko olungafunekiyo kwiindawo zetsimbi ngaphambi kokuqhubela phambili okanye unyango olungaphezulu. Ukuhambelana kwe-perchlorethylene kunye neentsimbi ezahlukeneyo, kuquka i-aluminium, intsimbi, kunye nobhedu, yenza ukuba i-solvent esebenzayo kwinkqubo yokunciphisa isinyithi.

3. Ukuveliswa kweekhemikhali: I-Perchlorethylene isebenza njengekhemikhali ephakathi kwimveliso yeendidi ezahlukeneyo. Isebenza njenge-precursor yokwenziwa kwe-vinyl chloride, ephinda isetyenziswe kwimveliso ye-polyvinyl chloride (PVC). Ukongeza, ikwasetyenziswa xa kusenziwa iipeyinti, izinto zokuncamathelisa, irabha kunye namayeza.

Izilumkiso zokhuseleko:

1. Ukhuseleko emsebenzini: Njengayo nayiphi na imichiza, amanyathelo afanelekileyo okhuseleko kufuneka athathwe xa kuphathwa i-perchlorethylene. Nxiba izixhobo ezifanelekileyo zokuzikhusela (PPE), ezinjengeeglavu kunye neeglavu, ukuthintela ukudibana ngokuthe ngqo. Indawo yokusebenza enomoya owaneleyo kunye nenkqubo yokucoca umoya ibalulekile ukuze kuncitshiswe ukuchanabeka kumphunga wekhemikhali.

2. Impembelelo yokusingqongileyo: Ngenxa yokukwazi ukungcolisa umhlaba, umoya kunye namanzi, i-perchlorethylene ihlelwa njengengozi yokusingqongileyo. Ulawulo olululo lwenkunkuma kunye neenkqubo zokulahla zidlala indima ebalulekileyo ekuthinteleni ukonakala kwendalo. Ukurisayikilishwa okanye ukulahlwa okufanelekileyo kwe-perc esetyenzisiweyo kuyacetyiswa ukuba kuncitshiswe ukukhululwa kwayo kokusingqongileyo.

3. Iingozi zempilo: Ukuvezwa ixesha elide kwi-vinyl chloride kunokuba nemiphumo emibi yempilo, kuquka iingxaki zokuphefumla, isiyezi kunye nokucaphuka kwesikhumba. Ngoko ke, kubalulekile ukuba abasebenzi bafumane uqeqesho olululo kwiinkqubo zokuphatha ngokukhuselekileyo kunye nokuthobela imida emiselweyo yokuba sesichengeni.

Isiphelo:

Ukuqukumbela, i-perchlorethylene ibaluleke kakhulu kumashishini amaninzi, ngokukodwa ekucoceni okomileyo, ukuchithwa kwesinyithi kunye nokuveliswa kweekhemikhali. Ukuqondwa ngokucokisekileyo kweempawu zayo, usetyenziso, kunye noqwalaselo lokhuseleko kubalulekile ukuze kuqinisekiswe ukusetyenziswa ngokukuko kunye nokunciphisa umngcipheko. Ngokuziqhelanisa neemfihlo ezisemva kwale khompawundi iguquguqukayo, sinokwenza izigqibo ezinolwazi kwaye sikhuthaze indawo ekhuselekileyo yokusetyenziswa kwayo.
