阀控密封铅酸蓄电池除了胶体电池用软质PVC 外，还有AGM 型阀控密封铅酸蓄电池超细玻纤隔板（AGM ）作为阀控密封铅酸蓄电池的电解液支撑体系，它大量吸附电解液，而且兼具隔板作用，可防止正负极间短路。AGM 的主要属性有：a ．吸酸／电解液量大而且吸酸快，能维持300mm 高度的酸液；b ．孔径小、吸酸吸液性好、保液性好；c ．内阻小．d ．耐酸；e ．为提供氧扩散通道，有极高氧复合能力，失水少。
AGM 吸液式玻纤垫有极大的表面积与极高的孔隙率，孔体积90 ％一95 % ，因而能吸附大量电解液。AGM 由100 ％玻纤组成，用造纸方法生产，纤维可有粗有细搭配，细纤维多性能高，但成本也高。通常不用猫合剂，它的基重（lmm 厚lmZ 的质量）为60 ? 3759 。
AGM 应有极高的机械强度，同时应具有如下特性。
a ．定量10kp 厚度，140g / m2（基厚lmm ) ，基本质量
lookp 厚度，210g / m2 （基厚lmm ) ，基本质量
b ．最大孔径20-25-ūm
c ．平均孔径10-ūm
d ．电阻0.05Ω·cm2 / mm
e ．孔体积95 %
f ．吸酸量7mL / g
9 ．伸长率2 %
AGM 用的原料是“C ”级玻璃，" E ' ，级玻璃用于增强型料（玻璃钢）, " E ' ，级玻璃不太耐酸，失重较大。“C ' ，级玻璃普遍用来生产AGM 。
The valve controls and seals completely sour storage battery of lead in addition to in addition to using soft PVC, gum body battery also an AGM type valve controls and seals completely super thin Bo Xian of sour storage battery of lead and separates plank(AGM) as the electrolyte that valve controls and seals completely lead sour storage battery props up system, it in great quantities adsorbs electrolyte, and possesses ～ and ～ and separates a plank function, can keep plus or minus pole from short circuit.The AGM main attribute has:A.absorb sour/the electrolyte have great capacity and absorb sour quick, can maintain a 300 mm highly of sour liquid;B.the bore path is small and absorb sour absorb a liquid good, protect a liquid good;C.inside the Zu is small. d.acid-proof;E.in order to provide oxygen proliferation passage, have very Gao Yang to reunite ability, lose water little.
AGM absorbs the liquid type Bo Xian the mat have tremendous surface to accumulate to lead with the highest hole, bore physical volume 90% is one 95%, as a result can adsorb a great deal of electrolyte.AGM constitutes to°from 100% Bo Xians and uses deckle method production, the fiber can be thick is thin to match, the thin fiber is much function Gao, but the cost is also high.Usually need not cat matches, is its radicle heavy(lmm the quality of the thick lmZ) to 60?3759.
AGM should have the highest machine strength, should have the following characteristic at the same time.
A.metered 10 kp thickness, 140 gs| m 2(radicle thick lmm), basic quality
Lookp thickness, 210 gs| m 2(radicle thick lmm), basic quality
B.the biggest bore path 20-25-ū m
C.average bore path 10-ū m
D.the electric resistance is 0.05 Ωs ·cm 2| mms
E.bore physical volume 95%
F.absorb sour measure a 7 mls| g
9.the elongation lead 2%
The raw material that AGM uses is "C" class glass, " E', the class glass is used for strengthening a type to anticipate(glass steel), " E', the class glass isn't that acid-proof, lose heavy a little bit greatly."C', the class glass widespreadly uses to produce AGM.
