UPS閥控密封電池先進(jìn)設(shè)計(jì)型AGM隔板 |
| UPS閥控密封鉛酸蓄電池電解液支撐體系分膠體技術(shù)用膠體、吸附式玻纖兩大類(lèi)。其中AGM 在發(fā)展，開(kāi)發(fā)AGMS （超細(xì)玻纖棉）由硼硅玻璃為原料，通過(guò)火焰拉絲，其單絲直徑0.25-4um 范圍。這種玻纖具有堅(jiān)實(shí)性與柔性，可以通過(guò)造紙方法濕式鋪層生產(chǎn)片式材料。超細(xì)玻纖棉的微孔結(jié)構(gòu)與對(duì)酸接觸角為零，所以它具有較高的芯吸作用。 先進(jìn)設(shè)計(jì)的AGM 有“活性物質(zhì)”（促進(jìn)氧擴(kuò)散與傳送）與“板柵結(jié)構(gòu)”（極好的拉伸強(qiáng)度）的特點(diǎn)，以下是先進(jìn)設(shè)計(jì)AGM 的要求。① 表面積表面積直接影響電池壽命與電池性能的主要參數(shù)。表面積與孔的大小有關(guān)，通�？自叫”砻娣e越大，表面積涉及對(duì)強(qiáng)度的影響，AGM 應(yīng)有一定強(qiáng)度，才能確保電池壽命。強(qiáng)度與表面積及厚度有關(guān)．作為技術(shù)進(jìn)步及越來(lái)越多的經(jīng)驗(yàn)積累認(rèn)為表面積不能太強(qiáng)調(diào)，向較小表面積趨勢(shì)的走向。由當(dāng)前1.1 ② 可壓縮性組裝電池的壓縮比是一個(gè)重要參數(shù)，壓縮比不應(yīng)低于10 % ，也不能過(guò)高大于40％，這樣會(huì)損壞AGM ，使其不能恢復(fù)彈性，濕態(tài)時(shí)壓縮比會(huì)降低，AGM 收縮，所以干態(tài)壓縮比應(yīng)有更高的壓縮。 ③ 隔板厚度選擇薄隔板對(duì)高率放電的電池更合適，對(duì)于低率放電的電池，儲(chǔ)存電解液盡可能多一點(diǎn)，要求隔板厚一點(diǎn)。對(duì)起動(dòng)型（SLI ) 電池AGM 厚度是正極厚的1-1.5 倍。 ④ 隔板的滲透性AGM （或AGMs ）的滲透性對(duì)電解液“分層”現(xiàn)象的發(fā)生至關(guān)重要。在富液式電池里，由于充電析氣的攪拌作用能使電解液分層現(xiàn)象得以消除。對(duì)于閥控密封鉛酸蓄電池電解液“貧”化，AGM 的滲透力值越低越優(yōu)異，通常AGM 滲透力值為2 一10 達(dá)西（Darcy )（多孔介質(zhì)滲透力值單位）。滲透力是一個(gè)參數(shù)，是測(cè)量物質(zhì)對(duì)牛頓流體的阻量大小，并以此計(jì)算孔結(jié)構(gòu)，不同粗細(xì)玻纖組成的AGM （或AGMs ）中細(xì)纖維含量多，AGM 才有更多的優(yōu)點(diǎn)。 The valve controls to seal completely sour storage battery electrolyte of lead to prop up system a gum body technique for cent is used gum body and the adsorb type Bo Xian is two major types.Among them in the development, AGM's development AGMS(super thin cotton of Bo Xian) is been a raw material by the glass of Peng Huo, pulls silk through a flame, it list the silk diameter 0.25-4 um scope.This kind of Bo Xian has solid with gentle, can spread through a wet type of deckle method the 1 F production slice type material.The tiny bore structure of super thin cotton of Bo Xian and to sour contact Cape is zero, so it has higher Xin to absorb a function. AGM of advanced design has "live material"(promote oxygen proliferation and transmission) with the characteristics of "plank grid structure"(best pull to stretch strength), is the request that the forerunner designs AGM as follows.①The surface accumulates the main parameter that the surface accumulates direct influence battery life and battery function.The surface accumulates to relate to the size of bore, usually the bore more small surface accumulates more big, the surface accumulates to involve the influence to the strength, AGM should have certain strength, so as to ensure battery life.The strength has something to do with surface accumulating and thickness. is technique progress and more and more experience backlogs to think that the surface accumulates to emphasize too much, toward the alignment that smaller surface accumulates trend.From current 1.1-1.3 ms 2| gs is 2| g developments to the 0.79-0.9 ms, however the surface accumulates decrease will also invite strength to lower, insulate sex to lower, the "the anti- lead wears a sting" dint lowers.The trend that Gao surface accumulates should be commendable, Gao surface accumulates to bear high pressure for assembling battery to shrink a ratio and consumedly improves battery circulating life span.The surface accumulates to still influence Xin to absorb the velocity that the function carries on.The AGM(or AGMS) Xin that the low surface accumulates absorbs the velocity that the function carries on Gao, but the Xin absorbs height limited, still recommend an use to Gao Xing's battery Gao the surface accumulate AGM. ②Condensability sex assembles the compression of battery than is an important parameter, compress compare don't should be lower than 10%, also can not lead is higher big than 40%, will damage AGM like this, it can not resume flexibility, wet Tai compress than will lower, AGM constringency, so stem Tai compression than should have higher compression. ③Separate plank thickness to choose thin separate the battery that the plank turns on electricity to Gao Lu more suitable, battery turn on electricity to the low rate, store electrolyte possibly more, request that separating plank is a little bit thicker.To start the type(SLI) battery AGM thickness is a cathode thick of 1-1.5 times. ④Separate knothole to permeate permeating of sex AGM(or AGMs)'s sex to the taking place of the electrolyte"layering" phenomenon is to the pass importance.At rich liquid type battery in, because of refresh the agitation function of Xi spirit can make electrolyte layering the phenomenon can get rid of.Control to seal completely sour storage battery electrolyte"poverty" of lead to turn to the valve, permeating of AGM the dint value is more low more excellent, usually AGM permeates dint to be worth to 2 a 10 reach west(Darcy).(many bores lie quality to permeate a dint value unit)Permeating the dint is a parameter, is measure the material has great capacity to the Zu of Newton's fluid small, and computes bore structure with this, the dissimilarity thick thin Bo Xian constitutes of the thin fiber content in AGM(or AGMs) is many, AGM just has more advantages. |
