Menene Kayayyakin Insulation marasa Halogen?

(1)Ƙarƙashin Hayaki mai Haɗin Haɗe-haɗe Zero Halogen Polyethylene (XLPE) Abubuwan Insulation:
Ana samar da kayan rufi na XLPE ta hanyar haɓaka polyethylene (PE) da ethylene vinyl acetate (EVA) a matsayin matrix na tushe, tare da ƙari daban-daban irin su halogen-free flame retardants, lubricants, antioxidants, da dai sauransu, ta hanyar haɓakawa da pelletizing tsari. Bayan sarrafa iska mai iska, PE yana jujjuyawa daga tsarin kwayoyin halitta na linzamin kwamfuta zuwa tsari mai girma uku, yana canzawa daga kayan thermoplastic zuwa filastik thermosetting maras narkewa.

Kebul na rufin XLPE suna da fa'idodi da yawa idan aka kwatanta da PE na thermoplastic na yau da kullun:
1. Inganta juriya ga nakasawar thermal, haɓaka kayan aikin injiniya a yanayin zafi mai yawa, da haɓaka juriya ga fashewar yanayin muhalli da tsufa na thermal.
2. Ingantattun kwanciyar hankali na sinadarai da juriya mai ƙarfi, rage kwararar sanyi, da kuma kiyaye kaddarorin lantarki. Yanayin aiki na dogon lokaci zai iya kaiwa 125 ° C zuwa 150 ° C. Bayan aikin haɗin giciye, za a iya ƙara yawan zafin jiki na ɗan gajeren lokaci na PE zuwa 250 ° C, yana ba da damar yin amfani da mafi girma na yanzu don igiyoyi na kauri ɗaya.
3. XLPE-insulated igiyoyi kuma suna nuna kyakkyawan kayan aikin injiniya, mai hana ruwa, da kaddarorin radiation, suna sa su dace da aikace-aikace daban-daban, irin su na'urorin lantarki na ciki a cikin kayan lantarki, jagorancin mota, jagorancin hasken wuta, ƙananan ƙananan wutar lantarki na siginar sigina, wayoyi masu amfani da locomotive. , Kebul na jirgin karkashin kasa, igiyoyin hakar ma'adinai masu dacewa da muhalli, igiyoyin jirgin ruwa, igiyoyi masu daraja 1E don tashoshin makamashin nukiliya, igiyoyin famfo mai ruwa da ruwa, da igiyoyin watsa wutar lantarki.

Hanyoyi na yanzu a cikin ci gaban kayan haɓaka kayan haɓakawa na XLPE sun haɗa da kayan kwalliyar wutan lantarki na kebul na igiya mai haɗaɗɗiya PE, kayan kwalliyar iska mai iska mai iska mai ƙoshin iska, da kayan kwalliyar wutan lantarki mai ɗaukar hoto polyolefin.

(2)Abun rufe fuska na Polypropylene (XL-PP) mai haɗin kai:
Polypropylene (PP), a matsayin filastik na yau da kullun, yana da halaye irin su nauyi mai sauƙi, wadataccen tushen albarkatun ƙasa, ƙimar farashi, kyakkyawan juriya na lalata sinadarai, sauƙin gyare-gyare, da sake yin amfani da su. Duk da haka, yana da iyakancewa irin su ƙananan ƙarfi, rashin juriya mai zafi, gagarumin raguwa na lalacewa, rashin juriya mara kyau, ƙananan zafin jiki, da rashin juriya ga zafi da tsufa na oxygen. Waɗannan iyakoki sun taƙaita amfani da shi a aikace-aikacen kebul. Masu bincike sunyi aiki don gyara kayan polypropylene don inganta aikin su gaba ɗaya, kuma irradiation cross-linked modified polypropylene (XL-PP) ya shawo kan waɗannan iyakoki yadda ya kamata.

Wayoyin da aka keɓe na XL-PP na iya saduwa da gwajin harshen wuta na UL VW-1 da UL-rated 150°C wayoyi. A aikace-aikacen kebul na aiki, ana haɗe EVA sau da yawa tare da PE, PVC, PP, da sauran kayan don daidaita aikin layin rufin kebul.

Ɗayan rashin lahani na PP mai haɗe-haɗe da iska mai iska shine cewa ya haɗa da amsa gasa tsakanin samuwar ƙungiyoyin ƙarewa mara kyau ta hanyar lalata halayen da halayen haɗin kai tsakanin ƙwayoyin tsoka da manyan radicals free radicals. Nazarin ya nuna cewa rabon lalacewa zuwa halayen haɗin kai a cikin haɗin kai na PP irradiation giciye yana da kusan 0.8 lokacin amfani da hasken gamma-ray. Don cimma tasiri mai tasiri mai mahimmanci a cikin PP, masu haɓaka haɗin gwiwar suna buƙatar ƙarawa don haɗakar da iska mai iska. Bugu da ƙari, ingantaccen kaurin haɗin haɗin giciye yana iyakance ta ikon shigar da katakon lantarki yayin da iska mai iska. Rashin iska yana haifar da samar da iskar gas da kumfa, wanda ke da fa'ida don haɗa samfuran bakin ciki amma yana iyakance amfani da igiyoyi masu kauri.

(3) Mai Haɗin Haɗin Ethylene-Vinyl Acetate Copolymer (XL-EVA) Kayan Kaya:
Yayin da buƙatun amincin kebul ɗin ke ƙaruwa, haɓaka kebul na igiyoyi masu alaƙa da wuta mara halogen ya haɓaka cikin sauri. Idan aka kwatanta da PE, EVA, wanda ke gabatar da vinyl acetate monomers a cikin sarkar kwayoyin halitta, yana da ƙananan crystallinity, yana haifar da ingantacciyar sassauci, juriya mai tasiri, daidaitawar filler, da abubuwan rufewar zafi. Gabaɗaya, kaddarorin resin EVA sun dogara da abun ciki na monomers na vinyl acetate a cikin sarkar kwayoyin halitta. Mafi girman abun ciki na acetate na vinyl yana haifar da ƙara bayyana gaskiya, sassauci, da tauri. Gudun EVA yana da ingantaccen dacewa mai filler da haɗin haɗin kai, yana sa ya zama sananne a cikin igiyoyi masu alaƙa da harshen wuta-free halogen.

EVA resin tare da abun ciki na vinyl acetate kusan 12% zuwa 24% ana yawan amfani dashi a cikin rufin waya da na USB. A cikin ainihin aikace-aikacen na USB, ana haɗe EVA sau da yawa tare da PE, PVC, PP, da sauran kayan don daidaita aikin Layer rufin kebul. Abubuwan EVA na iya haɓaka haɗin giciye, haɓaka aikin kebul bayan haɗin giciye.

(4) Mai Haɗin Haɗin Ethylene-Propylene-Diene Monomer (XL-EPDM) Kayan Kaya:
XL-EPDM terpolymer ne wanda ya ƙunshi ethylene, propylene, da diene monomers waɗanda ba a haɗa su ba, masu haɗin kai ta hanyar iska mai iska. XL-EPDM igiyoyi sun haɗu da fa'idodin igiyoyi masu rufi na polyolefin da igiyoyi masu rufi na yau da kullun:
1. Sassauci, juriya, rashin mannewa a yanayin zafi mai zafi, tsayin daka na tsufa, da juriya ga yanayin zafi (-60 ° C zuwa 125 ° C).
2. Ozone juriya, UV juriya, aikin rufin lantarki, da juriya ga lalata sinadarai.
3. Juriya ga mai da kaushi kwatankwacin maƙasudin chloroprene roba rufi. Ana iya samar da shi ta amfani da kayan aikin sarrafa zafi mai zafi na kowa, yana sa ya zama mai tsada.

XL-EPDM-insulated igiyoyi suna da nau'ikan aikace-aikace, ciki har da amma ba'a iyakance ga ƙananan igiyoyin wutar lantarki ba, igiyoyin jirgin ruwa, igiyoyin wuta na mota, igiyoyi masu sarrafawa don compressors na firiji, ma'adinan wayar hannu, kayan aikin hakowa, da na'urorin likita.

Babban rashin amfani na igiyoyi na XL-EPDM sun haɗa da ƙarancin juriya na hawaye da ƙarancin mannewa da kaddarorin mannewa kai, wanda zai iya rinjayar aiki na gaba.

(5) Silicone Rubber Insulation Material

Silicone roba yana da sassauci da kyakkyawan juriya ga ozone, fiɗar korona, da harshen wuta, yana mai da shi kayan da ya dace don rufin lantarki. Babban aikace-aikacen sa a cikin masana'antar lantarki shine don wayoyi da igiyoyi. Silicone roba wayoyi da igiyoyi sun dace musamman don amfani a cikin yanayin zafi mai zafi da buƙatu, tare da tsawon rayuwa mai mahimmanci idan aka kwatanta da daidaitattun igiyoyi. Aikace-aikacen gama gari sun haɗa da injuna masu zafin jiki, masu canza wuta, janareta, kayan lantarki da lantarki, igiyoyi masu kunna wuta a cikin motocin sufuri, da wutar lantarki da igiyoyin sarrafawa.

A halin yanzu, igiyoyin roba na silicone galibi suna haɗe-haɗe ta hanyar amfani da matsi na yanayi tare da iska mai zafi ko tururi mai ƙarfi. Har ila yau, ana ci gaba da gudanar da bincike kan yin amfani da hasken wutar lantarki don yin amfani da robar siliki mai haɗin kai, duk da cewa har yanzu bai zama ruwan dare a masana'antar kebul ba. Tare da ci gaba na baya-bayan nan a cikin fasahar haɗin kai ta hanyar iska mai iska, yana ba da ƙarancin farashi, mafi inganci, da madadin yanayin muhalli don kayan siliki na roba. Ta hanyar hasken wutar lantarki na lantarki ko wasu kafofin watsa labaru, ingantaccen haɗin giciye na rufin siliki na roba za a iya samu yayin ba da damar sarrafawa kan zurfin da matakin haɗin giciye don saduwa da takamaiman buƙatun aikace-aikacen.

Don haka, aikace-aikacen fasahar haɗin kai da iska mai iska don kayan rufin roba na silicone yana riƙe da alƙawari mai mahimmanci a cikin masana'antar waya da na USB. Ana sa ran wannan fasaha za ta rage farashin samarwa, inganta yadda ake samarwa, da kuma ba da gudummawa don rage mummunan tasirin muhalli. Ƙoƙarin bincike na gaba da haɓakawa na iya ƙara haɓaka yin amfani da fasahar haɗin kai ta hanyar iska mai iska don kayan haɗin roba na silicone, wanda ya sa su zama mafi dacewa don kera yanayin zafi, manyan wayoyi da igiyoyi a cikin masana'antar lantarki. Wannan zai samar da ƙarin abin dogara da kuma dorewa mafita ga daban-daban aikace-aikace yankunan.
