Wake wema ukucabanga ngalokho okugcina izintambo ekhaya lakho, ehhovisi, noma emotweni zisebenza ngokuphephile—ngisho noma ziboshwe ngaphansi kophahla olushisayo, zigqitshwe ngaphansi komhlaba, noma zicindezelwa ukusetshenziswa kwansuku zonke? Impendulo ilele entweni encane kodwa enamandla: Iziqinisi ze-PVC. Lezi zithasiselo ezingashiwongo yizona ezenza izintambo zakho zikagesi zingancibiliki, ziqhekeke, noma ziqhekeke ngokuhamba kwesikhathi. Ake sihlole ukuthi kungani zingaxoxiswani ngezintambo nezintambo, nokuthi yiziphi izinhlobo ezivelele.
Okokuqala: Kungani i-PVC Ibalulekile Ngezintambo Nezintambo
I-PVC (i-polyvinyl chloride) ikhona yonke indawo ezintanjeni. Yi-insulation eguquguqukayo nehlala isikhathi eside egoqa izintambo zethusi, izivikele emswakama, ekushiseni, nasekulimaleni ngokomzimba. Kodwa nansi inkinga: I-PVC ayizinzile ngokwemvelo. Uma ivezwa emazingeni okushisa aphezulu (njengokuvela kugesi), imisebe ye-UV, noma ngisho nesikhathi nje, iqala ukuwohloka. Lokhu kuphazamiseka kukhipha amakhemikhali ayingozi (njenge-chlorine) futhi kwenza i-insulation ibe buthaka—izindaba ezimbi lapho lokho kufakwa kwe-insulation kuyikho kuphela okuma phakathi kwakho ne-short circuit noma umlilo.
Faka Iziqinisi ze-PVC: Isivikelo Esivikelayo
Iziqinisi zifana nabaqaphi bokuvikela ukuvikela i-PVC.
Yilwa nomonakalo wokushisa: Izintambo zikagesi zikhiqiza ukushisa, futhi iziqinisi zivimbela i-PVC ekuncibilikeni noma ekuwohlokeni lapho amazinga okushisa enyuka (cabanga ngo-70°C+ ebhokisini lokuhlangana eligcwele abantu).
Melana nemisebe ye-UV: Ngezintambo zangaphandle (njengalezo ezisebenzisa izibani zasemgwaqweni), iziqinisi zivimba ukukhanya kwelanga ukuze kuvinjwe ukufudumala ekuqhekekeni noma ekuphelelweni.
Yeka ukubuthakatha: Ngokuhamba kweminyaka isetshenziswa, i-PVC ingaqina futhi iqhekeke. Ama-stabilizer ayigcina iguquguquka, ngisho nasemagaraji abandayo noma ema-attic ashisayo.
Gcina ukuphepha kukagesi: Ngokulondoloza ubuqotho bokufudumeza, zivimbela ama-short circuits, ukuvuza, kanye nemililo kagesi.
Iziqinisi Ezinhle Kakhulu Zezintambo Nezintambo
Akuwona wonke ama-stabilizer akulungele umsebenzi. Nazi izinketho eziphezulu zokuxhuma izintambo:
1. Iziqinisi ze-Calcium-Zinc: Kuphephile Futhi Kunobungani Nemvelo
Lezi yizindinganiso zegolide zezintambo zesimanje neziphephile:
Akunabo ubuthi: Njengoba zingenazo izinsimbi ezisindayo (njenge-lead noma i-cadmium), zihlangabezana nezindinganiso zokuphepha eziqinile (i-REACH, i-RoHS) zokusetshenziswa ngaphakathi nangaphandle. Zilungele amakhaya, izikole, kanye nezibhedlela lapho ukuphepha kubalulekile khona.
Ukumelana nokushisa ne-UV: Ziphatha amazinga okushisa aphakathi nendawo (kufika ku-90°C) kanye nokuchayeka ngaphandle, okwenza zibe zinhle kakhulu ezintanjeni zezintambo zasekhaya kanye nezintambo ezine-voltage ephansi (njengezintambo ze-USB).
Kulula ukucutshungulwaNgesikhathi sokukhiqiza, zixubana kahle ne-PVC, okuqinisekisa ukuthi ukuvikela akunazikhala noma izindawo ezibuthakathaka.
2. Izithambisi zeBarium-Zinc: Kunzima Ngezintambo Ezifunwa Kakhulu
Uma izintambo zidinga ukusingatha izimo ezimbi kakhulu, iziqinisi ze-barium-zinc ziyathuthuka:
Ukubekezelelana kwezinga lokushisa eliphezulu: Zikhula kahle ezindaweni ezishisayo (105°C+), okwenza zibe zilungele izintambo zezimboni, izintambo zemoto (ngaphansi kwe-hood), noma izintambo zikagesi ezinamandla aphezulu.
Ukuqina kwesikhathi eside: Zimelana nokuguga, ngakho-ke izintambo zihlala iminyaka engaphezu kwengu-20 ngisho nasezindaweni ezinzima (njengezimboni noma isimo sezulu sasehlane).
Kuqiza kahle: Zilinganisela ukusebenza kanye nentengo, okwenza zibe yintandokazi yamaphrojekthi amakhulu (cabanga ngamagridi kagesi noma izakhiwo zezentengiselwano).
3. Izithambisi Ze-Organic Tin: Ukunemba Kwezicelo Ezibalulekile
Lokhu kusetshenziswa ezintanjeni ezikhethekile nezisebenza kahle kakhulu:
Ukuvikela okucacile kwekristalu: Zigcina i-PVC icacile, okuwusizo kumakhebula e-fiber optic noma kuma-wiring ezokwelapha lapho ukubonakala kubalulekile khona.
Ukufuduka okuphansi kakhulu: Azikhiphi amakhemikhali, okwenza aphephe ezindaweni ezibucayi (njengemishini yezokwelapha noma izimboni zokucubungula ukudla).
Qaphela: Zibiza kakhulu kune-calcium-zinc noma i-barium-zinc, ngakho-ke zigcinelwe ukusetshenziswa okukhethekile.
Kwenzekani Uma Ungazisebenzisi Izithambisi?
Ukukhetha isiqinisi esingalungile (noma okuncane kakhulu) kungaholela enhlekeleleni:
Imifantu yokuvala umoya: Umswakama uyangena, okubangela ukujikeleza okufushane noma ukushaqeka kukagesi.
Ukuncibilika ngaphansi kokushisa: Izintambo ezisendaweni eshisayo (njengemuva kwama-TV) zingancibilika, zibangele imililo.
Ukwehluleka kwangaphambi kwesikhathiIzintambo zingadinga ukushintshwa eminyakeni engu-5-10 esikhundleni sengu-30+, okuzodla isikhathi nemali.
Indlela Yokubona Izinzinzi Zekhwalithi Ezisezintanjeni
Uma uthenga izintambo noma izintambo, funa:
IzitifiketiAmalebula anjenge-“UL Listed” (US) noma “CE” (EU) asho ukuthi ikhebula liphumelele ukuhlolwa kokuphepha—kufaka phakathi ukusebenza kwe-stabilizer.
Izilinganiso zokushisa: Amakhebula abhalwe ukuthi “90°C” noma “105°C” asebenzisa iziqinisi ezakhelwe ukushisa.
Idumela lomkhiqizoAbakhiqizi abathembekile (njengePrysmian noma iNexans) batshala imali kuzinzisi zekhwalithi ukuze bagweme ukubuyiselwa emuva.
Umcabango Wokugcina: Izinzisi = Izintambo Ezithembekile Neziphephile
Ngesikhathi esizayo uma uxhuma idivayisi noma uvula iswishi yokukhanyisa, khumbula: ukufakelwa kwe-PVC okuzungeze lezo zintambo kutholakala kumandla ayo ngenxa yeziqinisi. Kungakhathaliseki ukuthi kuyinii-calcium-zincekhaya lakho nomai-barium-zincNgezintambo zezimboni, isiqinisi esifanele sigcina ugesi ugeleza ngokuphephile—namuhla, kusasa, kanye namashumi eminyaka ezayo.
Phela, uma kukhulunywa ngezintambo, ukuthi “ngaphandle kokubona” akufanele kusho ukuthi “ngaphandle kokubona.” Okuhle kakhuluiziqinisisebenza buthule, ukuze ungalokothi ukhathazeke.
