Ngokuphathelele kumaqondo obushushu exesha elide asebenzayo kwi-Cable, i-inshureyi yerabha idla ngokuhlala kwi-65 ° C, i-COLONIYL CHORINID (PVC) kwi-70 ° C, kunye ne-Polythylene enxulumene ne-90 ° C. Kwisekethe elifutshane (elinexesha elininzi elingagqithanga kwimizuzwana emi-5), owona maqondo owona maqondo obunzima opholileyo osisigxina une-160 ° C nge-PVC i-I-25 ° C ukuba i-xlpe incloble.
I. Umahluko phakathi kwe-XPPE CANS kunye ne-PVC yentambo
I-1. I-Voltage ephantsi inxibelelene (i-XPE) ye-culbs, ukusukela kwintshayelelo yawo ngo-1990, ngokunikela i-Akhawuntingi ye-Preyviny ye-Polyvinyl Chride (PVC). Xa kuthelekiswa neentambo ze-PVC, i-XPPE CABS EXIBELELWANO ZOKHUSELEKO LWEZOBUCHULE BENKONZO Xa uvutha, i-PVC ikhuphe umsi omnyama onesibindi kunye negesi enetyhefu, ngelixa i-XLP COUSTONP ayivelisi iigesi zetyhefu yetyhefu. Ukuphakama kweentambo ezinxulumene nokugqobhoza kuya kwamkelwa ngakuyilo kunye namacandelo osetyenziso.
2. I-PVC eqhelekileyo ye-PVC (i-insulliser kunye ne-sheath) itshise ngokukhawuleza nge-quation ekhawulezayo, imililo ekhuthazayo. Baphulukana namandla abonelele amandla ngaphakathi kwemizuzu emi-1 ukuya kwezi-2. I-PVC ikhuphe umsi omnyama omnyama, okhokelela ekuphefumleni ubunzima kunye nemiceli mngeni yokufuduka. Ngokuthe ngcembe, ukukhutshwa kwe-PVC kukhupha ityhefu enetyhefu kunye ne-geroges efana ne-hydrogen chloride (i-HCL) kunye neDCLL, ezona zinto zibangela ukuba zibulawe kwi-80% yokufa komlilo. Ezi geses zinombala kwizixhobo zombane, ukugungxula ngokusebenza ngokufihlakeleyo kunye nokukhokelela kwiingozi zesekondari ekunzima ukuzinciphisa.
II. Intambo yedangatye
I-1. I-CAMURE-SORDERENS ifanele ibonakalise iimpawu ezihlawulelwayo zedami kwaye zahlulwe zangamanqanaba amathathu abuyiselweyo A, B, kunye ne-C ngokwee-IEC 6033-24 "kwiintambo zombane." Iklasi A inikezela ngeyona ndlela iphakamileyo yelangatye.
Iimvavanyo zokudibana okuthe tye kwi-Flame-Reardistant kunye neengcingo ezihlawulelwayo zedabha zedabha zenziwa liMigangatho ye-US kunye neTekhnoloji yoPhando. Ezi ziphumo zilandelayo zibalaselisa ukubaluleka kokusebenzisa iintambo zedangatye.
a. I-cingo ye-flame-retardint ibonelela kangangezihlandlo ezili-15 ixesha lokubaleka ixesha elithelekiswa neengcingo ezingafunekiyo.
b. Iingcingo zedangatye zedangatye zitshisa kuphela isiqingatha semibandela eninzi njengeingcingo engafakwanga.
c. Iingcingo zedangatye-ezihlawulelweyo zibonisa ireyithi yokukhutshwa kobushushu kuphela ikota yeso singo le-non-flame-remeardent.
d. Ukukhutshwa kwegesi enetyhefu ukusuka kwi-quards sisithathu kuphela kwezo zemveliso ezingengomadangatye.
e. Intsebenzo yokutsha komsi ibonisa umahluko obalulekileyo phakathi kwelanga - i-flander-i-on-flame-i-non-flame-ihlawule.
I-2. I-Halogn-free-free-ayinamsi
I-Halogn-free-free-free kunye ne-halogn-free halogn-free, umsi ophantsi, kunye neempawu zedangatye, kunye nokuchazwa kulandelayo:
IEC 60754 (Uvavanyo lweHalogn-Simahla Akukho mlinganiselo IEC 61034 (Uvavanyo lomsi ophantsi)
I-PH yenzaka lula ukukhanya
Ph≥4.3 r≤10s / mm t≥60%
I-3. Iintambo ezinganyangekiyo zomlilo
a. Ikholathi yovavanyo oluchasene ne-firess ander Ngokutsho kwe-IEC yakutshanje kwi-IEC yakutshanje ye-IEC, iqondo lokushisa lomlilo lisusela kwi-750 ° C ukuya kwi-800 ° C kangangeyure ezintathu.
b. Iingcingo ezinganyangekiyo zomlilo kunye neentambo zinokuhlelwa kwi-flame-retiardent yomlilo kunye neentambo ezingekho mthethweni-ezixhaphakileyo zedanga lomlilo ngokusekwe kulwahluko kwizinto ezingezizo ezingezizo ezomeleleyo. Iintambo ezinganyangekiyo zasekhaya zisebenzisa abaqhubi abanamakhaya ikakhulu uMica kunye nokufakwa kwelangatye ephekisiweyo njengeyona nto iphambili kuzo, ngokusebenzisa iimveliso zeklasi. Abo bahlangabezana neklasi imigangatho basebenzise iitephu ze-mica ezikhethekileyo zokufakwa kunye ne-Mineral Shorhel (i-Copper Copeve, I-Popper Deleve, Magnesium Oxide, ekwabizwa ngokuba yi-MI) ye-MI) yokunganyangeki.
Iintambo ezinganyangekiyo zomlilo ezingahambelaniyo azinanziweyo, aziveli msi, ziyinto engekho buhlungu, engenabungozi, kwaye ixhathise isitshizi samanzi. Baziwa ngokuba ziintambo zomlilo, ebonisa eyona ndlela yokusebenza yempumlo engapheliyo yomlilo phakathi kweentlobo zentambo ezingakhathalelwanga umlilo. Nangona kunjalo, inkqubo yabo yokwenziwa kwayo inzima, iindleko zabo ziphezulu, ubude babo bulinganiselwe, ukugoba kwazo kuninzi, i-diving ikhululwe kumswakama, kwaye okwangoku, ngaphezulu kunokubonelelwa. Iziphelo ezinikezelweyo ezizinikeleyo kunye nezihloko eziphakathi ziyimfuneko, yenza ufakelo kunye nokwakha kunye nokwakha.
