Epoxy filament-wound insulation tubes are a big step forward in high-performance electrical insulation technology because they have both great dielectric strength and great mechanical longevity. Precision-wound fiberglass strands filled with high-quality epoxy resin systems are used to make these advanced tubular insulators. The result is cylinder-shaped structures that work well in harsh industrial settings. The epoxy filament-wound insulation tube design offers the best thermal stability, chemical resistance, and structural integrity for electrical power systems, industrial machinery, and specialized manufacturing sectors that need reliable insulation performance in harsh conditions.

Textolite material, which combines phenolic resin with paper or cotton cloth as a substrate to make flexible laminated sheets, is an important industrial insulation option. These composite materials are great for electrical insulation in electronics, power systems, and machinery production because they are very strong and stable at high temperatures. Textolite materials are used by industrial engineers and procurement teams for parts of switchgear, transformer insulation, and precision-machined electrical parts that must meet high standards of stability and performance.

FR4 sheet is the most common substrate material used in the electronics businesses around the world and is the building block of modern PCB production. This in-depth guide looks at why FR4 is the most popular material for PCBs because it has the best electrical insulation qualities, is very durable, and is also very cheap. When engineering managers and procurement teams know about FR4's technical specs, manufacturing methods, and buying strategies, they can make decisions that improve performance and stick to the budget.

Izimoto zikagesi zishintshe indlela izimoto ezenziwe ngayo futhi zibeka ingcindezi enkulu ekuphepheni kwebhethri kanye nezinhlelo zokulawula ukushisa ezingakaze zibonwe ngaphambili. Amashidi okuvikela ukushisa ayizinkanyezi ezingakadunyiswa zezinhlelo zokusebenza zebhethri le-EV. Avikela ekushiseni, ugesi, kanye nomlilo, okubalulekile kokubili ekusebenzeni nasekuphepheni. Lezi zinto ezikhethekile zivimba ukusabalala kokushisa, zigcina ukuhlukaniswa kukagesi kwezinhlelo zamandla aphezulu kuvinjelwe, futhi zakha izindonga zokuphepha ezibalulekile ngaphakathi kwezingxenye zebhethri. Onjiniyela abasebenza esigabeni esilandelayo sezimoto zikagesi kanye nezinhlelo zokugcina amandla kudingeka bazi okuningi ngezinhlobo ezahlukene zamashidi okuvikela ukushisa, izakhiwo zawo, nokuthi angasetshenziswa kanjani ngendlela efanele.

Ukuze uthole ukusebenza okuhle kakhulu ezintweni zokuvikela ze-epoxy fiberglass zokusetshenziswa kwezentengiselwano, kubalulekile ukwazi umehluko phakathi kwe-FR4, G10, kanye ne-G11. I-FR4 ilungele izinto zikagesi ngoba ayibambi umlilo futhi inezinga le-UL94 V-0 ngenxa ye-bromine engeziwe kuyo. I-G10 inamandla angcono okusebenza kunezinye izinto ezikhona emakethe ngaphandle kokusebenzisa izinto ezivimbela ilangabi. Iphinde ibe namandla okudonsa angcono kanye nokumelana nokumanzi kokusetshenziswa kwamandla aphezulu. I-G11 isebenza kahle ezindaweni ezishisayo ngoba izinzile kangcono ekushiseni kufika ku-180°C. Lokhu kuyenza ifaneleke kakhulu ezimbonini ezifana nezindiza nezimoto ezidinga ubukhulu obuzinzile ezimweni ezinzima.

Amashubhu e-Bakelite alaminethiwe awuhlobo olubalulekile lwezinto zokufakelwa ezihlanganisiwe ezenziwe ngokubeka ngokucophelela indwangu, ilineni, noma iphepha nge-phenolic resin eqina lapho amazinga okushisa aphezulu. Izindlela ezikhethekile zokupholisa ukushisa nokucindezela zisetshenziswa kulezi zingxenye ezimise okwesilinda ukuze ziqine ngokwanele ukusetshenziswa ezindaweni eziningi zezimboni zezinto ezifana nokufakelwa kukagesi, isikhala semishini, kanye nokuvikelwa kokushisa. Uma uxuba izinto zokuqinisa eziphilayo ne-phenolic resin chemistry, uthola ukusebenza okuhle kakhulu, ukuzinza kobukhulu, kanye nokusebenza okungabizi kakhulu onjiniyela banamuhla abathembele kukho ezingxenyeni ezibalulekile zesistimu.

Lolu uhlobo oluhle kakhulu lwe-fiberglass epoxy laminate, futhi izinto ze-Garolite zinezimfanelo ezinhle zokuvikela ugesi kanye namandla amakhulu omshini. Lezi zinto ezihlanganisiwe ezithuthukisiwe zenziwe ngendwangu yengilazi elukiwe exutshwe ne-epoxy resin ukwenza izinto eziqinile ezingasetshenziswa ezindaweni ezinzima zezimboni. Izimfanelo zokusebenza okuphezulu ze-Garolite zisiza onjiniyela nabaphathi bokuthenga ezimbonini eziningi ezahlukene ukuqinisekisa ukuthi kuhlangatshezwana nezidingo eziqinile zemishini kagesi, izinhlelo zamandla, kanye nezingxenye zemishini enembile.

Ukuze ukhethe i-laminate yengilazi-epoxy engcono kakhulu phakathi kwezinto ze-G10 ne-FR4, udinga ukwazi ukuthi zisebenza kanjani ezindaweni ezibalulekile zezimboni nokuthi umehluko wazo oyisisekelo uthinta kanjani ukukhetha kwakho. Yakhiwe ngezindwangu zengilazi ezilukiwe ezifakwe i-epoxy resin emsulwa. Amapuleti namashidi e-fiberglass e-G10 angama-laminate ane-thermosetting ephezulu anamandla amakhulu omshini kanye nezimfanelo zokushisa zikagesi ngaphandle kwezithasiselo ezivimbela ilangabi. Ngenkathi amakhemikhali afakwe i-brominated ku-FR4 enza ukuthi ingashi, i-G10 ingcono ekwenzeni izingxenye zikagesi, ama-spacer omshini, kanye nezingxenye zezimboni ezinembile ezidinga okungcono kakhulu ekuqineni kwesakhiwo, ukuzinza kobukhulu, kanye nomshini wokugaya.

Lapho onjiniyela bezimboni bedinga izinto zokuvikela eziqinile ezingagugi futhi ezikwazi ukuvimba ugesi, i-phenolic cotton cloth laminate ivelele njengesinqumo esingcono kakhulu. Le nto eguquguqukayo inamandla amakhulu okusebenza, ukuqina kwezinga lokushisa okuhle, kanye nezakhiwo zikagesi ezinhle, okwenza ibe yinto ebalulekile embonini yezimoto, imishini yezimboni kanye nokukhiqiza ugesi. Ukwazi izici zayo ezikhethekile nokuthi ingasetshenziswa kanjani kusiza ochwepheshe bokuthenga benze izinqumo ezihlakaniphile ezithuthukisa ukusebenza ngenkathi begcina izindleko ziphansi.
