Intshayelelo kwi-BS 5308 Icandelo 1 Uhlobo 2 Intambo ye-PE/IS/OS/PE/SWA/PVC
I. Isishwankathelo
I-BS 5308 Icandelo 1 Uhlobo 2 Intambo ye-PE/IS/OS/PE/SWA/PVC yimveliso yentambo eyenzelwe ngokukodwa ukuhlangabezana neemeko ezahlukeneyo zesicelo esintsonkothileyo. Indibaniselwano yayo eyahlukileyo yesakhiwo ibonisa izinto eziqwalaselweyo ngokubanzi ngokubhekiselele ekusebenzeni kombane, ukhuseleko loomatshini, kunye nokuguquguquka kwendalo, kwaye isetyenziswa kakhulu kwiindawo ezahlukeneyo zoshishino, zokwakha, kunye nezakhiwo ezikhethekileyo.
II. Ulwakhiwo lwesakhiwo
(I) I-Polyethylene (PE) I-Inner Insulation Layer (IS)
Isiqinisekiso Esiphambili Sokufakwa Kombane
Njengomgca wokuqala wokukhusela ubushushu ngaphakathi kwentambo, umaleko we-PE wangaphakathi wobushushu unamandla obushushu aphezulu. Ungawuthintela ngempumelelo umbane ongaqhelekanga phakathi kwee-conductors, ukuqinisekisa ukuba amandla ombane adluliselwa kwindlela emiselweyo. Uphawu lwayo lokumelana nobushushu obuphezulu luvumela intambo ukuba igcine imeko yobushushu obuhle xa iphantsi kombane olinganisiweyo okanye nokuba ikwiqondo elithile lobushushu obungaphezulu, nto leyo ethintela iimeko eziyingozi ezifana nee-electrical short - circuits.
Inkxaso yoZinzo lweZakhiwo
Umaleko we-insulation yangaphakathi ye-PE uyafana ngobume kwaye unobungqingqwa obuthile, unika inkxaso ezinzileyo kwisakhiwo sangaphakathi sentambo. Xa intambo iphantsi kwamandla angaphandle afana nokugoba, ukolula, okanye ukucinezelwa kancinci, inokugcina imo yayo kunye nokusebenza kwe-insulation yombane, ngaloo ndlela iqinisekisa ukuthembeka kwesakhiwo sentambo iyonke kunye nokuzinza kokusebenza kombane.
(II) I-Polyethylene (PE) Umaleko Wokugquma Wangaphandle (OS)
Ukusebenza Kokugquma Kombane Okuphuculweyo
Umaleko wokufakelwa kwangaphandle we-PE ongaphandle komaleko wokufakelwa kwangaphakathi uphucula ngakumbi amandla okufakelwa kombane wentambo. Isebenza ngaxeshanye nomaleko wokufakelwa kwangaphakathi, yenza ukhuseleko lokufakelwa kombane olunamaleko amabini, inciphisa kakhulu umngcipheko wokuvuza kwamandla kwaye iphucula ukhuseleko lwentambo kwiindawo zombane ezintsonkothileyo. Kwezinye iindawo ezineemfuno eziphezulu kakhulu zokufakelwa kombane, ezifana nezitishi ezincinci kunye neeworkshops zezixhobo ze-elektroniki ezichanekileyo, olu lwakhiwo lokufakelwa kombane olunamaleko amabini lwe-PE lunokuhlangabezana ngempumelelo nemigangatho engqongqo yokufakelwa kombane.
Uzinzo lweeKhemikhali kunye nokufuma - Ipropati ethintela ukufuma
Umaleko wokugquma wangaphandle we-PE unozinzo oluhle lweekhemikhali kwaye unokumelana nokukhukuliseka kwezinto zangaphandle zeekhemikhali. Kwangaxeshanye, ukwanayo nepropati ethile yokumelana nokufuma, ethintela ukufuma ekungeneni ngaphakathi kwentambo kwaye ithintela ukwehla kokusebenza kombane okanye umonakalo kumaleko wokugquma obangelwa yindawo enomswakama, ngaloo ndlela yandisa ubomi benkonzo yentambo.
(III) Isixhobo Sokuxhoma Iingcingo Zentsimbi (i-SWA)
Umqobo woKhuselo lweMishini
Isikhuselo sentsimbi sisakhiwo esibalulekileyo sokukhusela intambo. Sinokumelana noxinzelelo olunamandla lwangaphandle loomatshini, njengokukhupha izinto ezinzima emhlabeni ngexesha lokubeka phantsi komhlaba, ukungqubana nezixhobo kwiindawo zoshishino, kunye neempembelelo ezingalindelekanga ngexesha lokwakha. Esi sakhiwo someleleyo sokuzikhusela sikhusela ngokufanelekileyo umaleko wokukhusela kunye nee-conductors ngaphakathi kwentambo, siqinisekisa ukuba intambo isakwazi ukusebenza ngokuqhelekileyo kwindawo enzima yoomatshini.
Ukusebenza kakuhle kokukhusela i-electromagnetic
I-SWA inefuthe elikhulu lokukhusela i-electromagnetic. Kwiindawo ezine-electromagnetic interference, ezifana nezixhobo zamandla ezinkulu kunye nezikhululo zonxibelelwano, i-steel wire armor inokuthintela ngempumelelo ukuphazamiseka kwentsimi ye-electromagnetic yangaphandle kwi-signal transmission ngaphakathi kwi-cable, kwaye ikwathintele imiqondiso yangaphakathi ye-cable ukuba ingakhanyisi ngaphandle ukuze iphazamise ezinye izixhobo, ukuqinisekisa ukuchaneka kunye nokuzinza kokudluliselwa kwesignali.
(IV) Isingxobo sangaphandle sePolyvinyl Chloride (PVC)
Ukhuseleko lweNdalo yangaphandle
I-PVC yangaphandle sheath ibonelela ngokhuseleko olupheleleyo lwangaphandle lwentambo. Ingamelana nokungena kwezinto ezahlukeneyo ezingqongileyo, kubandakanya imisebe ye-ultraviolet, ukubola kweekhemikhali, kunye nokugruzuka koomatshini. Kwimeko engaphandle evezwe ngaphandle, i-PVC yangaphandle sheath inokuthintela impembelelo yokuguga yemitha ye-ultraviolet elangeni kwizinto zangaphakathi zentambo; kwimeko eneekhemikhali, inokumelana nokuguguleka kwezinto zeekhemikhali; kwiindawo ezinengxaki yokungqubana rhoqo, njengakwiitreyi zentambo zangaphakathi, inokunciphisa umonakalo kwintambo obangelwa kukugruzuka koomatshini.
Umsebenzi wokuchonga nokwahlulahlula
Umbala weshelufu yangaphandle yePVC unokwenziwa ngokwezifiso ngokweemfuno ezahlukeneyo zesicelo, nto leyo ibaluleke kakhulu kwinkqubo yocingo lwentambo entsonkothileyo. Iishelufu zangaphandle zemibala eyahlukeneyo zingasetyenziswa ngokulula ukuchonga injongo, inqanaba levolthi, okanye isekethe enxulumeneyo yentambo, njl.njl., nto leyo enceda ekuchongeni intambo ngokukhawuleza nangokuchanekileyo ngexesha lokufakwa, ukugcinwa, kunye neenkqubo zokufumana iimpazamo, ukuphucula ukusebenza kakuhle komsebenzi.
