Lub neej ntev ntawm 70 xyoo uas muaj tib lub neej raws li lub tsev zoo li cas?

Lub neej ntev 70 xyoo cableyog tsim nyog rau txhua qhov chaw uas muaj cov pejxeem tuab, xws li cov khw muag khoom, chaw ua yeeb yam, chaw nres tsheb, tshav dav hlau thiab lwm qhov chaw pej xeem, nrog rau cov kab tseem ceeb, kev tsim vaj tsev, kho kom zoo nkauj hauv tsev, thiab lwm yam.

Lub neej kev pab cuam ntawm cov khoom no tsis tsawg tshaj li 70 xyoo ntawm qhov nruab nrab kev khiav hauj lwm kub ntawm 70 ° C.Lub sij hawm ntev tso cai ua haujlwm kub ntawm tus neeg xyuas pib yog 90 ° C, 105 ° C, thiab 125 ° C;Qhov siab tshaj plaws kev khiav hauj lwm kub thaum lub sij hawm luv luv Circuit Court (ntau tshaj 5S) yog 250 ° C.

Cov kab hluav taws xob rwb thaiv tsev siv hluav taws xob sib txuas ob txheej txheej rwb thaiv tsev.Lub rwb thaiv tsev sab hauv ua tau raws li cov hluav taws xob rwb thaiv tsev kev ua tau zoo, cov rwb thaiv tsev sab nrauv ua tau raws li cov nplaim hluav taws kub ua haujlwm, thiab cov txheej txheem sab hauv thiab sab nrauv ib txhij ua tau raws li lub neej ua haujlwm siab.

Cov laj thawj thiab qhov zoo ntawm kev siv hluav taws xob sib txuas rau kev rwb thaiv tsev (piv nrog PVC zoo tib yam): Cov khoom siv PVC tsoos tsis zoo thermal stability.

Nws ua nyuaj thiab nkig ntawm qhov kub thiab txias, thiab yooj yim softens thiab so ntawm qhov kub thiab txias.Nws muaj kev cuam tshuam tsis zoo thiab kev laus ua haujlwm, yooj yim tso tawm cov pa phem ntawm qhov kub thiab txias, thiab yooj yim tso cov khoom tsis zoo thaum tsim khoom thiab siv, ua rau muaj kev phom sij rau tib neeg thiab ib puag ncig.

Radiation cross-linking siv cov kab hluav taws xob hluav taws xob siab uas tsim los ntawm cov hluav taws xob accelerators los hloov cov khoom qub zoo li cov qauv molecular rau hauv peb-dimensional network molecular qauv los tsim cov kab sib txuas.

Peb-dimensional network molecular qauv muaj cov thermal stability zoo, thiab cov rwb thaiv tsev, hluav taws xob thiab cov khoom siv kho kom zoo tuaj.Kev txhim kho tseem ceeb.

Qhov zoo ntawm kev ua tau zoo yog raws li hauv qab no
Lub neej cable yog synchronized nrog lub tsev: 70 xyoo.Vim tias qhov kub thiab txias tsis kam thiab siab aging kub ntawm irradiation cross-linked rwb thaiv tsev, lub neej kev pab cuam ntawm lub cable uas generates tshav kub thaum siv yog ncua.
Lub peev xwm nqa loj: irradiation cross-linked cable nce los ntawm kev sib txuas tsis sib txuas 70 ° C mus rau 90 ° C, 105 ° C, thiab 125 ° C.
Kev rwb thaiv tsev loj: Txij li cov hluav taws xob sib txuas sib txuas tsis txhob siv cov hydroxide ua cov nplaim hluav taws, nws tiv thaiv kev sib txuas ua ntej thaum sib txuas thiab qhov txo qis hauv rwb thaiv tsev vim qhov nqus dej noo hauv huab cua los ntawm txheej rwb thaiv tsev.Qhov no ua kom cov nqi hluav taws xob tiv thaiv.
Cov khoom lag luam ruaj khov: Qhov zoo ntawm cov khoom siv hluav taws xob sib txuas sib txuas (feem ntau hu ua cov dej sov cables) cuam tshuam los ntawm dej kub, txheej txheem extrusion, kev sib txuas ntxiv thiab lwm yam, thiab qhov zoo tsis ruaj khov, thaum qhov zoo ntawm irradiation hla -linked cables nyob ntawm cov kab hluav taws xob.Cov koob tshuaj irradiation yog tswj los ntawm lub computer, uas txo cov tib neeg yam, yog li qhov zoo yog ruaj khov.
Cov nplaim hluav taws kub hnyiab: Cov khoom siv hluav taws kub kub yog siv, thiab ZA, ZB, ZC, thiab cables tuaj yeem tsim raws li cov neeg siv khoom xav tau.Cov nplaim hluav taws kub ua haujlwm tau dhau qhov kev ntsuas hluav taws xob tau teev tseg hauv GB / T 1966-2005.
Halogen-dawb, tsis muaj toxicity, tsis muaj pa luam yeeb: qhov tsawg kawg nkaus lub teeb kis ntawm thawj-chav kawm nplaim-retardant nyob ntawm tej thiab thawj-chav kawm hluav taws-resistant xov hlau tsis tsawg tshaj li 80%, thiab qhov tsawg kawg nkaus lub teeb transmittance ntawm lwm yam nyob ntawm tej thaum hlawv tsis tsawg. 60% acidity PH tus nqi ntawm cov roj combustion yuav tsum tsis pub tsawg tshaj 4.3, thiab cov conductivity yuav tsum tsis txhob ntau tshaj 10us/mm.
