Intshayelelo

Indalo:

1. Lulwelo olungenambala nevumba elimnandi nelimnandi.

2. I-Volatile, ivutha kakhulu, i-soluble kwi-solvents yezinto eziphilayo kunye ne-inorganic acids.

 

Ukusetyenziswa:

1. Njenge-solvent ye-organic esetyenziswa ngokubanzi kwishishini lemichiza, idlala indima ebalulekileyo ekutsalweni kwe-solvent, ukuchithwa, kunye nokulungiswa kwee-agent zokucoca.

2. Ibhiphenylinokusetyenziswa njengento ekrwada kunye nephakathi kwizinto ezahlukeneyo zeekhemikhali, ezisetyenziselwa ukuhlanganiswa kwedayi, iiplastiki, irabha kunye nezinye iimveliso.

3. Isenokusetyenziswa njengokongeza amafutha, i-automotive coolant, kunye necandelo lezikhuseli zezityalo.

 

Indlela:

Kukho iindlela ezininzi, eyona ixhaphake kakhulu kukuqhekeka kwetela yamalahle. Ngokusabela kokuqhekeka kwetela yamalahle, iqhezu elixubeneyo eliqulethe i-biphenyl linokufumaneka, kwaye emva koko i-biphenyl yococeko oluphezulu inokufumaneka ngokucocwa kunye neendlela zokwahlula.

 

Ulwazi lokhuseleko:

1. Ibhiphenyllulwelo olunokutsha olunokubangela imililo xa luvezwe kwimithombo yomlilo okanye amaqondo obushushu aphezulu. Ke ngoko, kubalulekile ukuhlala kude namadangatye avulekileyo, imithombo yobushushu, kunye nombane ongatshintshiyo.

2. Umphunga webiphenyl unetyhefu ethile kwaye unokucaphukisa inkqubo yokuphefumla, inkqubo yemithambo-luvo kunye nolusu. Ke ngoko, izixhobo ezifanelekileyo zokukhusela kufuneka zinxitywe kwaye kuqinisekiswe indawo yokusebenza engenawo umoya.

3. Iibiphenyls nazo zinokubangela umonakalo kwizinto eziphilayo zasemanzini, ngoko ke kufuneka zithintelwe ukuba zingakhutshelwa emanzini.

4. Xa uphethe kwaye ugcina i-biphenyls, ukuthotyelwa ngokungqongqo kwiinkqubo ezifanelekileyo zokusebenza zokhuseleko kufuneka kulandelwe ukuphepha ukuvuza kunye neengozi.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
