Ziziphi iihalogens?
Izinto ezifana ne-fluorine, i-chlorine, i-bromine, i-iodine kunye ne-astate ziyi-halogens kwaye zivela kwiqela lesixhenxe eliphambili kwi-periodic table yezinto.Zifumaneka kwiikhompawundi ezininzi zeekhemikhali, umzekelo kwi-polyvinylchloride.I-PVC, njengoko yaziwa ngokuba mfutshane, yomelele kakhulu, yiyo loo nto isetyenziswa kwiimveliso ezininzi zobugcisa, kunye nokugquma kunye nezixhobo zesheath kwiintambo.I-Chlorine kunye nezinye i-halogens zihlala zibandakanyiwe njengezongezo zokuphucula ukukhuselwa komlilo.Kodwa oko kuza nexabiso.IiHalogens ziyingozi empilweni.Ngenxa yesi sizathu, iiplastiki ezingenazo iihalojeni ziya zisetyenziselwa iintambo.
Yintoni intambo engena-halogen?
Njengoko igama labo libonisa, i-halogen-free cables ayinayo i-halogen ekubunjweni kweeplastiki.Iiplastiki eziqukethe i-halogens ziyakwazi ukuchongwa ngamacandelo amakhemikhali kumagama abo, njenge-polyvinyl chloride ekhankanywe ngaphambili, i-rubber chloroprene, i-fluoroethylene propylene, i-rubber ye-polymer ye-fluoro, njl.
Ukuba ufuna okanye kufuneka usebenzise iintambo ezingenazo i-halogen, qiniseka ukuba ezi ziquka iiplastiki ezifana nerabha ye-silicone, i-polyurethane, i-polyethylene, i-polyamide, i-polypropylene, i-thermoplastic elastomers (i-TPE) okanye i-ethylene propylene diene irabha.Azinazinzisi okanye izithambiso zentsimbi enzima, kwaye izongezo zokukhusela ilangatye zikhuselekile ngokusingqongileyo.
Zenziwa njani iintambo ezingenazo ihalogen?
Intambo ayinayo i-halogen ukuba akukho ma-halogens afana neklorini, i-fluorine okanye i-bromine esetyenziswayo kwi-insulation ye-cable kunye ne-sheath material.Amadlala ekhebhula, iinkqubo zethumbu, izihlanganisi okanye imibhobho ecuthekayo, efana neKHUSELA ityhubhu ecuthekayo ye-HFevela eMingxiu, isenokwenziwa nangeeplastiki ezingenazo ihalogen kwaye ke azinahalogen.Ukuba ufuna iintambo ezingenazo i-halogen, umzekelo, nceda uqaphele ezi zinto zilandelayo zemveliso:
| Iiplastiki zeHalogenated | Iiplastiki ezingenazo iHalogen |
| I-Chlorinephen-rabhaUmguboethylene Ipropylene Fluorpirabha ye-olymer PolyvinylUChloride | Irabha yeSiliconePolyurethane Polyethylene Polyamide Polypropylene Thermoplastic Iielastomers |
Kutheni iintambo ezingenazo ihalogen zibalulekile ekukhuseleni umlilo?
IiHalogens zingonakalisa impilo.Oku kunjalo ngakumbi xa iiplastiki ze-halogenated, ngakumbi i-PVC, zitshisa.Ukuba kuqhambuka umlilo, i-hydrogen halides iphuma kwiplastiki.I-halogens idibanisa namanzi, njengamanzi okucima asetyenziswa ngumlilo okanye ulwelo olusuka kwi-mucous membranes, ukwenza i-acids - i-chlorine iba yi-hydrochloric acid, i-fluorine i-hydrofluoric acid eyingozi kakhulu.Ukongeza, umxube we-dioxins kunye nezinye iikhemikhali ezinetyhefu kakhulu zinokuqulunqwa.Ukuba zingena kwimizila yomoya, zinokubangela umonakalo kwaye zibangele ukuphefumla.Nokuba umntu uyasinda emlilweni, impilo yakhe inokonakala ngokusisigxina.Oku kungaphantsi kakhulu kwimeko yeentambo ezingenazo i-halogen.
Ukukhusela umlilo odibeneyo, iintambo kufuneka zibe nokukhuselwa komlilo kunye nokuveliswa komsi ophantsi.Ukukhuselwa komlilo kunciphisa ukutsha kunye nokusasazwa komlilo kunye nokukhuthaza ukuzicima.Abavelisi bajongana nengxaki apha, njengoko iklorini kunye nebromine zezona zikwazi ukunqanda amadangatye, yiyo loo nto zihlala zixutywa neeplastiki zeentambo.Nangona kunjalo, ngenxa yeengozi zempilo ezikhankanyiweyo, oku kuyaphikisana kwaye kuvunyelwe kuphela apho kungekho bantu basengozini.Ngenxa yoko, uMingxiu usebenzisa izixhobo ezinomgangatho ophezulu wokukhusela amadangatye kodwa ngaphandle kweehalogens.
Yintoni inzuzo yeentambo ezingenazo i-halogen?
Ukuba iintambo ezingenazo ihalogen zifudunyezwa kakhulu okanye zitshiswe kakhulu, zenza iiasidi ezingadlekiyo okanye iigesi eziyingozi empilweni.Iintambo ze-XLPE okanye iintambo zedatha ezivela eMingxiu zifaneleke ngokukodwa ukuba zisetyenziswe kwizakhiwo zikawonke-wonke, izithuthi okanye ngokubanzi apho imililo inokwenzakalisa kakhulu abantu okanye izilwanyana okanye yonakalise impahla.Zinobuninzi berhasi yomsi ephantsi, ngoko ke zivelisa umsi omncinci kwaye zenza kube lula kubantu ababanjiweyo ukufumana iindlela zokubaleka.
Iintambo ezingenazo iHalogen ziluncedo ngakumbi ukuba ufuna ukuqinisekisa ugcino olusebenzayo oluphezulu xa kutsha.Oku kunokubaluleka kwizakhiwo apho iikhamera zokucupha zibonelela ngemifanekiso yomthombo womlilo.Intambo yedatha enesantya esiphezulu evela eMingxiu idlulisela idatha ngesantya esipheleleyo sothumelo nasemva kweeyure ezimbini kwidangatye.
