Phantse bonke abavelisi bajongene nemisebenzi yabo kunye nokumakishwa kwezambatho kunye neempawu zokunyamekela. Ukuba iimveliso ziveliswa kubathengi basekhaya, iimpawu zokunyamekela izinto ziboniswe ngokuqwalasela i-GOST. Ukwangoku, kukho imigangatho emibini karhulumente. Iyokuqala ibhekisela kwimpahla yokuvelisa ubuninzi, kwaye yesibini ibhekisela kwiingubo zabasebenzi, abaphathi be-FSB kunye noMphathiswa weMicimbi yangaphakathi.
Kwizambatho ezithunyelwa ngaphandle, iimpawu zomhlaba jikelele zokunyamekelwa kwezinto ziyasetyenziswa. Emva koko, ilizwe ngalinye linemigangatho yalo, izikhundla zalo, ngoko ke ukusetyenziswa kwamagama aqeshwe ngokubanzi kwenza kube lula inkqubo yokuvelisa impahla kunye nokuthunyelwa kwayo kuthengiswa kwelinye ilizwe.
Iimpawu kunye nemigangatho yazo
Iimpawu zokunakekelwa kweettile zichaphazela zonke izigaba zokunyamekela. Kwakhona kuthetha ukucocwa kweekhemikhali kwezambatho, kunye nokuhlamba, ukusetyana kunye nokomisa impahla. Kwaye ngamnye udidi lweemveliso ezikhethiweyo ezichanekileyo.
Kwakhona kwaziwa ukuba ubukhulu befayile nganye akumele kube ngaphantsi kwe-8 mm. Ipeyinti, esetyenziselwa ukusetyenziswa kweempawu, kufuneka ihluke kumbala apho umthunzi wesiqulatho selebula senziwa khona. Ngamanye amazwi, yonke inkcukacha yesimboli kufuneka ibonakale ngokucacileyo ngumthengi.
Ukuhanjiswa kweempawu ngelebula kulawulwa. Kwaye umyalelo ungolu hlobo lulandelayo: uphawu lokuqala lubonakalisa ukuhlamba kweempahla, ngoko-kwenzeka ukuba uhlambulule, ukucoca, uze uqaphele ukutyunjwa kokucoca, kwaye, ekugqibeleni, uphawu lokumisa umveliso.
Kodwa ekujonge imiqondiso, kufuneka ukwazi ukuba yonke imigaqo abonayo ibhekisela kwizinto eziyinxalenye yokwakheka okuyisiseko kwemveliso oyithengayo, ene-index esezantsi kakhulu yokumelana ne-thermal kunye ne-chemical.
Ziyintoni na izimboli?
Ukuba ukhangele uphawu lokuhlamba, yayazi ukuba inani elisetyikitya lithetha ukushisa kwamanzi. Omnye umgca ekusezantsi kwesibonakaliso uchaza malunga nokuhlamba okucokisekileyo, kwaye inani lokuhlamba elifakwe kumatshini wokuhlamba akufanele lidlule ngaphezu kwe-2/3 yexabiso elikhethiweyo. Ngokubhekiselele kwintambo yokugqithisa kwidrama, kuya kufuneka iyancitshiswa. Inani leenguqulelo ngexesha lokuphambukisa kufuneka linciphise, kwaye ngokukhangela okubhaliweyo, kuyimfuneko ukwenza ngokufanelekileyo.
Imigca emibini ejikelezayo ibonisa indlela ekhethekileyo yokuhlamba imveliso. Kwaye oku kuthetha ukuba inani lelineni kumatshini akufanele lidlule elinye elikhethiweyo ngaphezulu kwe-1/3. Umzuzu wokuguqa wokuhlamba kufuneka ube luninzi kunokwenzeka. Kwaye ixesha lokutshiza kunye nenani leenguqulelo liziswa ubuncinci.
Ekuqhubekeni kokuchazwa kweempawu zokunakekelwa kwezambatho, kufuneka kuqatshelwe ukuba ezi zimbini zinokuthi ukuba nangona uphendulela ngesandla, yenza ngokucophelela. Ngamanye amaxesha kukufanelekile ukushiya inkqubo yokugcoba iimpahla.
Kwilebula yengubo onokuyitshitshiswa yimiqondiso emininzi, ukwenzela ukuba kule ngqungquthela ungayidideki, ufunde ngokucophelela umzobo.
Ukucoceka kobugcisa
Ngokwahlukileyo, makhe sithethe ngokucoca uqeqesho lweemveliso, ezahlula zibe zomile kwaye zimanzi. Olu hlobo lokuqhutyelwa kweengubo lwenziwa kuphela kumaziko akhethekileyo. Ngokubhekiselele ekuhlambuleni, akusilo liziko elifanayo. Musa ukudibanisa le mibono.
Iimpawu ezibonisa iimpawu ezithile zokucoca iimpahla kwiziko elizodwa zilandelayo:
- "P" - Perchlorethylene, perchlorethylene (tetrachlorethylene);
- "F" - Inokutsha, iyatshisa;
- "A" - Nayiphi na, nayiphi na;
- "W" - Emanzi, emanzi.
Omnye umgca ohleliweyo ucwangcise ukuhlamba. Kwakhona kuyimfuneko ukunciphisa umswakama, ukushisa kunye nemiphumo emihle kwimveliso. Ngenxa yoko-amabini amabini abonisa ukuhla okubalulekileyo kwiimpawu zecoca zokucoca. Ukuze uthole iinkcukacha ezingakumbi malunga nenjongo yezondlo zokunakekelwa kweempahla, khangela isibalo.
