Isantya esiphakathiumatshini wekomityi yephephaluhlobo lwesikhongozeli sephepha esenziwe ngentlama yomthi wekhemikhali (ikhadibhodi emhlophe) ngokulungiswa ngoomatshini kunye nokuncamatheliswa.Imile okwekomityi kwaye ingasetyenziselwa ukutya okukhenkcezisiweyo kunye neziselo ezishushu.Ngeempawu zokhuseleko, ucoceko, ukukhanya kunye nokulula, sisixhobo esifanelekileyo seendawo zoluntu, iindawo zokutyela kunye neeresityu.Umatshini wekomityi yephepha elinesantya esiphezulu wahlulwe ngokweekomityi zephepha ezityathiweyo ezinecala elinye kunye neekomityi zephepha ezicatyiswe kabini zePE.Iikomityi zephepha ezityatyekwe ngecala elinye le-PE: Iikomityi zephepha eziveliswe ngecala elinye eligqunyiweyo zibizwa ngokuba ziikomityi zephepha ezigqunywe kwicala elinye (iikomityi zephepha kunye neekomityi zephepha lentengiso kwimarike yasekhaya ubukhulu becala ziikomityi zephepha ezigqunywe kwicala elinye).Ifom yokusebenza kwayo: icala lamanzi kwikomityi yephepha, kunye nefilimu ye-PE egudileyo.Iikomityi zephepha ezicatyiswe kabini ze-PE: Iikomityi zephepha ezenziwe ngephepha eliphindwe kabini le-PE libizwa ngokuba ziikomityi zephepha ze-PE.Ukusebenza: I-PE igqunywe ngaphakathi nangaphandle kweekomityi zephepha.
Indlela yokukhetha ikomityi yephepha eyenziwe yiumatshini wekomityi yephepha?
Indlela elungileyo yokukhetha iikomityi zephepha:
1 jonga mhlophe.Nje ukuba ezi zinto ziyingozi zingene emzimbeni womntu, ziya kuba zi-carcinogens ezinokubakho.Iingcali zicebisa ukuba xa abantu bekhetha iikomityi zephepha, kufuneka bakhanyise isibane phantsi kwesibane kakhulu.Ukuba indebe yephepha phantsi kwesibane se-fluorescent eluhlaza okwesibhakabhaka, ibonisa ukuba i-agent ye-fluorescent idlula umgangatho, kwaye abathengi kufuneka bayisebenzise ngokuqaphela.
(2) Pinki: umzimba wekomityi uthambile kwaye awuqini, kulumkele ukuvuza kwamanzi.Ukongezelela, kuyimfuneko ukukhetha ikomityi yephepha enodonga oluqinileyo kunye nolunzima.Ikomityi yephepha enobulukhuni obuphantsi bomzimba wekomityi ithambile kakhulu.Xa ugalela okanye usela amanzi, uya kuba nokukhubazeka kakhulu xa uwachola, okanye uwachole, okuya kuchaphazela ukusetyenziswa.Iingcali zithi iikomityi zephepha ezikumgangatho ophezulu ziyakwazi ukugcina amanzi kangangeeyure ezingama-72 ngaphandle kokuvuza, kwaye iikomityi zephepha ezikumgangatho ophantsi ziya kugalela amanzi kangangesiqingatha seyure.Ivumba: Umbala wodonga oluhle, lumkela ityhefu ye-inki.Iingcali zolongamelo lomgangatho zachaza ukuba ukuba iikomityi zephepha zipakishwe kunye, ukuba zifumile okanye zingcolisekile, ngokuqinisekileyo ziya kubumba, ngoko ke iikomityi zephepha ezimanzi mazingasetyenziswa.Ukongezelela, ezinye iikomityi zephepha ziya kuprintwa ngeepatheni ezinemibala kunye neetekisi.Xa iikomityi zephepha zidityanisiwe, ikomityi yephepha ngaphandle kwe-inki iya kuchaphazela ngokuqinisekileyo umaleko wangaphakathi wekomityi yephepha ehlanganiswe kuyo, kwaye i-inki ine-benzene kunye ne-toluene, eyingozi empilweni.Thenga iikomityi zephepha ezinamaleko angaphandle angena-inki okanye aprintwe kancinci.Injongo: Ukwahlula phakathi kweekomityi ezishushu kunye nezibandayo, "zenza indima yazo".Ekugqibeleni iingcali zabonisa ukuba iikomityi zephepha ezilahlwayo esiqhele ukuzisebenzisa zinokwahlulwa zibe ziindidi ezimbini: iikomityi zesiselo esibandayo kunye neekomityi zesiselo esishushu.
