Wakha wema ukuze ucinge ngento egcina iingcingo ekhayeni lakho, eofisini, okanye emotweni yakho zisebenza ngokukhuselekileyo—nokuba zigqunywe phantsi kophahla olushushu, zigqunywe phantsi komhlaba, okanye zisetyenziswa imihla ngemihla? Impendulo ikwinto encinci kodwa enamandla: Iziqinisi zePVC. Ezi zongezo zingadunyiswanga zezona zibangela ukuba iintambo zakho zombane zinganyibiliki, zingaqhekeki, okanye ziqhekeke ngokuhamba kwexesha. Makhe sijonge ukuba kutheni zingaxoxiswani ngeengcingo kunye neengcingo, kwaye zeziphi iintlobo ezibalaseleyo.
Okokuqala: Kutheni i-PVC ibalulekile kwiingcingo kunye neentambo
I-PVC (i-polyvinyl chloride) ifumaneka kuyo yonke indawo kwiintambo. Yi-insulation eguquguqukayo nehlala ixesha elide ejikeleza iingcingo zobhedu, izikhusela ekufuma, kubushushu, nakumonakalo womzimba. Kodwa nantsi into ebangela oku: I-PVC ayizinzanga ngokwendalo. Xa ibekwe kumaqondo obushushu aphezulu (njengombane), imisebe ye-UV, okanye kwanangexesha nje elifutshane, iqala ukubola. Oku konakala kukhupha iikhemikhali eziyingozi (ezifana ne-chlorine) kwaye kunciphisa i-insulation—iindaba ezimbi xa loo insulation ikuphela kwento ephakathi kwakho ne-short circuit okanye umlilo.
Ngena kwi-PVC Stabilizers: Isihlangu esiKhuselayo
Izibambisi-ndlela zifana nabagcini bezinto zokukhusela i-PVC.
Yilwa nomonakalo wobushushu: Iingcingo zombane zivelisa ubushushu, kwaye iziqinisi zithintela i-PVC ukuba inganyibiliki okanye yonakale xa amaqondo obushushu enyuka (cinga ngama-70°C+ kwibhokisi yokuxhuma enabantu abaninzi).
Melana nemisebe ye-UV: Kwiintambo zangaphandle (ezifana nezo zinika amandla izibane zasezitalatweni), izinto ezizinzisayo zivala ukukhanya kwelanga ukuze kuthintelwe ukuqhekeka okanye ukufiphala kobushushu.
Yeka ukuba buthathaka: Kwiminyaka emininzi isetyenziswa, i-PVC inokuqina ize iqhekeke. Izibambisi-ndlela ziyigcina iguquguquka, nokuba zikwigaraji ezibandayo okanye kwiindawo ezishushu.
Gcina ukhuseleko lombane: Ngokugcina ukhuseleko lobushushu, zithintela ii-short circuits, ukuvuza, kunye nemililo yombane.
Ezona Zinzisa Zilungileyo ZeeNtambo NeeCables
Ayizizo zonke izinto ezizinzisayo ezikwaziyo ukwenza lo msebenzi. Nazi ezona zinto zibalaseleyo zokufaka iingcingo:
1. IziQinisekisi zeCalcium-Zinc: Ikhuselekile kwaye inobuhlobo nokusingqongileyo
Le yimigangatho yegolide yentambo zanamhlanje nezikhuselekileyo:
Ayinatyhefu: Ayinazo iintsimbi ezinzima (ezifana ne-lead okanye i-cadmium), ziyahlangabezana nemigangatho yokhuseleko engqongqo (REACH, RoHS) yokusetyenziswa ngaphakathi nangaphandle. Ifanelekile emakhaya, ezikolweni, nasezibhedlele apho ukhuseleko lubalulekile khona.
Ukumelana nobushushu kunye ne-UV: Ziphatha amaqondo obushushu aphakathi (ukuya kuthi ga kwi-90°C) kunye nokuvezwa ngaphandle, nto leyo eyenza ukuba zibe zilungele ukufakelwa kweentambo zokuhlala kunye neentambo ze-voltage ephantsi (ezifana neentambo ze-USB).
Kulula ukuyisebenzisa: Ngexesha lokwenziwa, zixutywa kakuhle nePVC, ukuqinisekisa ukuba ubushushu abunazikhewu okanye amabala abuthathaka.
2. IziQinisekisi zeBarium-Zinc: Inzima kwiintambo ezifunwa kakhulu
Xa iingcingo zifuna ukujongana neemeko ezinzima, iziqinisi ze-barium-zinc ziyaphakama:
Ukunyamezelana nobushushu obuphezulu: Zikhula kakuhle kwiindawo ezishushu (105°C+), nto leyo eyenza ukuba zilungele iintambo zoshishino, iintambo zemoto (phantsi kwekhava), okanye iintambo zombane ezine-voltage ephezulu.
Ukuqina kwexesha elide: Ziyakwazi ukumelana nokwaluphala, ngoko ke iintambo zihlala iminyaka engaphezu kwama-20 nokuba zikwimeko enzima (njengemizi-mveliso okanye imozulu yasentlango).
Isebenza kakuhle emalini: Zilungelelanisa ukusebenza kunye nexabiso, nto leyo ezenza zibe zezona zithandwayo kwiiprojekthi ezinkulu (cinga ngeegridi zamandla okanye izakhiwo zorhwebo).
3. Izinto eziQinisekisa iTin ye-Organic: Ukuchaneka kwizicelo ezibalulekileyo
Ezi zisetyenziswa kwiintambo ezikhethekileyo nezisebenza kakuhle:
Ubushushu obucacileyo obukhanyayo: Zigcina i-PVC icacile, nto leyo eluncedo kwiintambo ze-fiber optic okanye kwiintambo zonyango apho ukubonakala kubalulekile khona.
Ukufuduka okuphantsi kakhulu: Azikhuphi iikhemikhali, nto leyo ezenza zikhuseleke kwiindawo ezinobuzaza (ezifana nezixhobo zonyango okanye iifektri zokulungisa ukutya).
Qaphela: Zibiza kakhulu kune-calcium-zinc okanye i-barium-zinc, ngoko ke zigcinelwe ukusetyenziswa kwiindawo ezithile.
Kwenzeka ntoni ukuba awusebenzisi izinto eziqinisa amandla?
Ukukhetha isizinzisi esingalunganga (okanye esincinci kakhulu) kunokukhokelela kwintlekele:
Imifantu yokuvala ubushushu: Ukufuma kuyangena, okubangela ii-short circuits okanye ukuqhawuka kombane.
Ukunyibilika phantsi kobushushuIintambo ezikwiindawo ezishushu (njengasemva kweeTV) zinokunyibilika, zibangele imililo.
Ukungaphumeleli kwangaphambi kwexeshaIingcingo zingadinga ukutshintshwa kwiminyaka emi-5 ukuya kweli-10 endaweni yeminyaka engama-30 nangaphezulu, nto leyo ebiza ixesha nemali.
Indlela yokubona izinto ezizinzisa umgangatho kwiintambo
Xa uthenga iingcingo okanye iintambo, khangela oku kulandelayo:
Iziqinisekiso: Iilebheli ezifana ne-“UL Listed” (US) okanye “CE” (EU) zithetha ukuba intambo iphumelele uvavanyo lokhuseleko—kuquka ukusebenza kwe-stabilizer.
Uvavanyo lobushushuIintambo eziphawulwe ngo-“90°C” okanye “105°C” zisebenzisa iziqinisi ezakhelwe ubushushu.
Udumo lwebhrendi: Abavelisi abathembekileyo (abafana nePrysmian okanye iNexans) batyala imali kwizixhobo ezizinzisayo ukuze baphephe ukubuyiswa kwakhona.
Ingcinga Yokugqibela: Izinzisi = Iintambo Ezithembekileyo Nezikhuselekileyo
Ngexesha elizayo xa ufaka isixhobo okanye uvula iswitshi yokukhanyisa, khumbula: ubushushu bePVC obujikeleze ezo ngcingo buxhomekeke kwizibambisi-ndlela. Nokuba yiyoi-calcium-zincekhaya lakho okanyei-barium-zincKwiintambo zoshishino, isizinzisi esifanelekileyo sigcina umbane usebenza ngokukhuselekileyo—namhlanje, ngomso, nakumashumi eminyaka ezayo.
Kaloku, xa kufikwa kwiingcingo, ukuthi “ngaphandle kokubona” akufanele kuthethe “ngaphandle kwengqondo.” Eyona nto ilungileyoiziqinisisebenza buthule, ukuze ungaze ukhathazeke.
