Ko tambo yemakore makumi manomwe yehupenyu hurefu ine hupenyu hwakafanana nechivako chinotaridzika sei?

Iyo 70-yemakore yakareba hupenyu tamboinokodzera nzvimbo dzese dzine vanhu vakawanda, senge mashopu, mabhaisikopo, zviteshi, nhandare dzendege nedzimwe nzvimbo dzeveruzhinji, pamwe nemitsetse yakakosha yekugovera, wiring yekuvaka, yekushongedza imba, nezvimwe.

Hupenyu hwesevhisi yechigadzirwa ichi hahusi pasi pemakore makumi manomwe paavhareji tembiricha ye70°C.Iyo yenguva yakareba inobvumirwa tembiricha yekushanda yetambo conductor ndeye 90 ° C, 105 ° C, uye 125 ° C;tembiricha yepamusoro yekushanda panguva pfupi (yepamusoro yenguva 5S) i250°C.

Iyo cable insulation layer inotora radiation cross-yakabatana kaviri-layer insulation chimiro.Iko kuvharidzira kwemukati kunosangana nekushanda kwemagetsi ekudzivirira kwemagetsi, kunze kwekunze kunosangana nekushanda kwemoto, uye mukati nekunze kwemukati panguva imwe chete inosangana nehupenyu hwepamusoro.

Zvikonzero uye zvakanakira kushandisa radiation cross-linking yekuvharisa (zvichienzaniswa neyakajairwa PVC): Yechinyakare PVC zvinhu hazvina kugadzikana kwekupisa kwekupisa.

Inova yakaoma uye brittle panguva yakaderera tembiricha, uye nyore kupfava uye kuzorora panguva yakakwirira tembiricha.Iine hurombo husina simba hwekuramba uye kuramba kuchembera, inoburitsa nyore magasi anokuvadza pakupisa kwakanyanya, uye inodonhedza nyore zvinhu zvinokuvadza panguva yekugadzira uye kushandiswa, zvichikonzera mhedzisiro yakaipa pavanhu uye nharaunda.

Radiation cross-linking inoshandisa high-energy electron matanda anogadzirwa neelectron accelerators kushandura cheni yepakutanga-yakafanana nemamorekuru chimiro kuita matatu-dimensional network mamorekuru maumbirwo kuti aumbe macross-link.

Iwo matatu-dimensional network mamorekuru chimiro ane yakanaka kugadzikana kwekupisa, uye iyo yekuvharisa, yemagetsi uye yemagetsi zvinhu inovandudzwa.Kuvandudza kukuru.

Mabhenefiti makuru ekuita ndeaya anotevera
Hupenyu hwetambo hunowiriraniswa nechivakwa: 70 makore.Nekuda kweyepamusoro tembiricha yekudzivirira nhanho uye yakanyanya kuchembera tembiricha ye irradiation cross-linked insulation, hupenyu hwesevhisi yetambo inoburitsa kupisa panguva yekushandiswa inowedzerwa.
Huru hwekutakura huwandu: irradiation-yakabatana tambo inowedzera kubva kune isiri-yakabatana 70 ° C kusvika 90 ° C, 105 ° C, uye 125 ° C.
Yakakura yekudzivirira kudzivirira: Sezvo radiation cross-linking inodzivirira kushandiswa kwehydroxide senge inodzoreredza murazvo, inodzivirira pre-cross-linking panguva yekuyambuka-yakabatana uye kuderera kwekudzivirira kwekudzivirira nekuda kwekutorwa kwemwando mumhepo neiyo insulation layer.Izvi zvinovimbisa kukosha kwekudzivirira kwe insulation.
Yakagadzika chigadzirwa mhando: Hunhu hwechinyakare silane-yakabatana tambo (inowanzo zivikanwa semvura inodziya tambo) inokanganiswa nekupisa kwemvura, extrusion process, cross-linking additives uye zvimwe zvinhu, uye mhando yacho haina kugadzikana, nepo mhando yeradiation cross. -akabatanidzwa netambo zvinoenderana nerekitironi danda.Iyo irradiation dose inodzorwa nekombuta, iyo inoderedza zvinhu zvevanhu, saka mhando yacho yakagadzikana.
High flame retardant: High flame retardant zvinhu zvinoshandiswa, uye ZA, ZB, ZC, uye tambo dzinogona kugadzirwa zvinoenderana nezvinodiwa nevatengi.Kuita kwemoto kudzoreredza kwakapfuura bvunzo yekupisa yakatsanangurwa muGB/T 1966-2005.
Halogen-isina, yakaderera muchetura, yakaderera utsi: iyo shoma mwenje transmittance yekutanga-kirasi-inodzoreredza waya waya uye yekutanga-kirasi-inodzivirira moto waya haisi isingasviki 80%, uye kushoma kwemwenje kupfuudza kwedzimwe waya pakupisa hakusi kushoma. kupfuura 60%.The acidity PH kukosha kwegesi inopisa haifaniri kuva pasi pe4.3, uye conductivity haifaniri kuva yakakura kudarika 10us / mm.
