3. Ukusebenza kakuhle kokusebenza
I-ASTMA53GR.B umbhobho wentsimbi ongenamthungo unokudityaniswa kakuhle, ukusika kunye neplastiki, okwenza kube lula ukusetyenzwa nokuyifaka. Ukongeza, izinto eziphathekayo zinokumelana nokushisa okuphezulu kunye nokuphantsi kwaye kunokugcina ukusebenza okuzinzileyo kwiindawo ezinzima.
Iinkalo zesicelo ze-ASTMA53GR.B umbhobho wentsimbi ongenamthungo
I-ASTMA53GR.B ipayipi yensimbi engenamthungo isetyenziswa ngokubanzi kwiindawo zothutho leoli, igesi yendalo, amanzi, umphunga kunye nezinye iindawo. Ngokukodwa kwezinye iimeko ezifuna ukumelana noxinzelelo oluphezulu kunye nobushushu obuphezulu, le nto yinto efunekayo. Ukongeza, i-ASTMA53GR.B imibhobho yentsimbi engenamthungo nayo isetyenziswa ngokuqhelekileyo kwiikhemikhali, amandla ombane, ulwakhiwo kunye namanye amashishini ukubonelela ngezinto ezithembekileyo zemibhobho kwiinkqubo ezahlukeneyo zokuhanjiswa kwamanzi.
Ukukhethwa kunye nokugcinwa kwe-ASTMA53GR.B umbhobho wentsimbi ongenamthungo
1. Izilumkiso xa uthenga
Xa uthenga umbhobho wentsimbi ongenamthungo we-ASTMA53GR.B, kuya kufuneka uthathele ingqalelo la manqaku alandelayo:
(1) Khetha abavelisi abaqhelekileyo ukuqinisekisa umgangatho wemveliso othembekileyo;
(2) Khangela ukuba iinkcukacha, imilinganiselo kunye nobukhulu bodonga lombhobho wentsimbi ziyahlangabezana neemfuno;
(3) Khangela umgangatho womphezulu wombhobho wensimbi ukuqinisekisa ukuba akukho ziphene ezicacileyo okanye umonakalo;
(4) Khetha izinto ezifanelekileyo zombhobho wentsimbi kunye neenkcukacha ngokwendawo yokusetyenziswa kunye neemfuno.
2. Amanyathelo olondolozo
Xa usebenzisa i-ASTMA53GR.B umbhobho wentsimbi ongenamthungo, kufuneka ubeke ingqalelo kwezi ngongoma zilandelayo:
(1) Ukuhlola nokugcina imibhobho rhoqo ukuze ibone kwaye ijongane neengxaki ngexesha elifanelekileyo;
(2) Gcina imibhobho icocekile kwaye yomile ukuthintela ukudleka kwangaphakathi nangaphandle kwemibhobho;
(3) Ngexesha lothutho kunye nofakelo, ingqwalasela kufuneka ihlawulwe ekukhuseleni umbhobho ukuphepha ukungqubana kunye nomonakalo;
(4) Imibhobho yentsimbi eyonakeleyo ifanele itshintshwe ize ilungiswe kwangethuba ukuze kuqinisekiswe ukhuseleko nokuzinza kwenkqubo yemibhobho.
Ukushwankathela, i-ASTMA53GR.B umbhobho wentsimbi ongenamthungo yimathiriyeli yombhobho esebenza ngokugqwesileyo kunye nemimandla yosetyenziso olubanzi. Ngethuba lokusetyenziswa, kufuneka ubeke ingqalelo kwimiba yokuthenga nokugcina ukuqinisekisa ukhuseleko kunye nokuzinza kwenkqubo yombhobho. Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe, i-ASTMA53GR.B ipayipi yentsimbi engenamthungo iya kusetyenziswa kwiinkalo ezininzi, izisa ukukhululeka kunye neenzuzo kwimveliso yabantu kunye nobomi.
