Ngaphezu kwalokho, le nto nayo inokumelana okuhle nokuguguleka kanye nokumelana nokushayisana, okungandisa ngempumelelo impilo yesevisi yepayipi.
2. Ukumelana nokugqwala okunamandla
Ipayipi lensimbi elingenamthungo le-ASTMA53GR.B lenziwe ngensimbi yesakhiwo sekhabhoni esezingeni eliphezulu. Ngemva kwenqubo eqinile yokwelashwa kokushisa, linokumelana okuhle nokugqwala futhi lingamelana nokuguguleka kwamakhemikhali anjenge-asidi nama-alkali, okuqinisekisa ukusebenza okuzinzile kwesikhathi eside kohlelo lwamapayipi.
3. Ukusebenza kahle kokucubungula
Ipayipi lensimbi elingenamthungo le-ASTMA53GR.B linokushibilika okuhle, ukugoba kanye nokuqina, okwenza kube lula ukulicubungula nokulifaka. Ngaphezu kwalokho, izinto zalo zinokumelana okuhle nokushisa okuphezulu nokuphansi futhi zingagcina ukusebenza okuzinzile ezindaweni ezinzima.
Izinkambu zokusetshenziswa kwepayipi lensimbi elingenamthungo le-ASTMA53GR.B
Ipayipi lensimbi elingenamthungo le-ASTMA53GR.B lisetshenziswa kabanzi emikhakheni yezokuthutha kawoyela, igesi yemvelo, amanzi, umusi kanye neminye imikhakha. Ikakhulukazi kwezinye izikhathi ezidinga ukumelana nomfutho ophezulu kanye nokushisa okuphezulu, le nto iyindlela ebalulekile. Ngaphezu kwalokho, amapayipi ensimbi angenamthungo e-ASTMA53GR.B avame ukusetshenziswa ezimbonini zamakhemikhali, zamandla kagesi, ezokwakha kanye neminye imikhakha ukuhlinzeka ngezinto zombhobho ezinokwethenjelwa zezinhlelo ezahlukene zokulethwa koketshezi.
Ukukhethwa nokugcinwa kwepayipi lensimbi elingenamthungo le-ASTMA53GR.B
1. Izinyathelo zokuphepha uma uthenga
Uma uthenga ipayipi lensimbi elingenamthungo le-ASTMA53GR.B, kufanele unake amaphuzu alandelayo:
(1) Khetha abakhiqizi abavamile ukuqinisekisa ikhwalithi yomkhiqizo ethembekile;
(2) Hlola ukuthi imininingwane, ubukhulu kanye nobukhulu bodonga lwepayipi lensimbi kuyahlangabezana yini nezidingo;
(3) Hlola ikhwalithi yobuso bepayipi lensimbi ukuqinisekisa ukuthi azikho iziphambeko noma umonakalo obonakalayo;
(4) Khetha izinto ezifanele zombhobho wensimbi kanye nemininingwane ngokuya ngendawo yokusetshenziswa kanye nezidingo.
2. Izinyathelo zokulungisa
Uma usebenzisa ipayipi lensimbi elingenamthungo le-ASTMA53GR.B, kufanele unake amaphuzu alandelayo:
(1) Hlola futhi unakekele amapayipi njalo ukuze uthole futhi ubhekane nezinkinga ngesikhathi esifanele;
(2) Gcina amapayipi ehlanzekile futhi omile ukuze kuvinjelwe ukugqwala kwangaphakathi nangaphandle kwamapayipi;
(3) Ngesikhathi sokuthutha nokufaka, kufanele kuqashelwe ukuvikela ipayipi ukuze kugwenywe ukushayisana nomonakalo;
(4) Amapayipi ensimbi alimele kufanele ashintshwe futhi alungiswe ngesikhathi ukuqinisekisa ukuphepha nokuzinza kohlelo lwamapayipi.
Ngamafuphi, ipayipi lensimbi elingenamthungo le-ASTMA53GR.B liyipayipi elisebenza kahle kakhulu kanye nezinkambu zokusetshenziswa ezibanzi. Ngesikhathi sokusetshenziswa, udinga ukunaka izinkinga zokuthenga nokulungisa ukuqinisekisa ukuphepha nokuzinza kohlelo lwamapayipi. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ipayipi lensimbi elingenamthungo le-ASTMA53GR.B lizosetshenziswa ezinkambu eziningi, okuzoletha ukulula kanye nezinzuzo ezengeziwe ekukhiqizweni nasekuphileni kwabantu.
