一、概述HYX系列数显陶瓷吸水率测定仪是采用真空法对日用陶瓷、建筑卫生陶瓷、电瓷、砖瓦、水泥制品的吸水率进行测定的仪器。本机符合国家标准GB/T3810.3-2006《陶瓷砖试验方法 第3部分：吸水率、显气孔率、表现相对密度和容重的测定》和国家标准GB/T3299-1996《日用陶瓷吸水率测定方法》中对试验设备的要求。First,outlineHYXisenumeraterevealstheceramicwater-absorptivitycryoscopeisuses真空法totheceramicsfordailyuse,thebuildingsanitaryearthenware,electricporcelaneous,thebricksandtiles,thecementproductwater-absorptivitycarriesonthedeterminationtheinstrument.ThismachineconformstonationalstandardGB/T3810.3-2006 theceramicceramictiletestingmethod□□3rdpart:Thewater-absorptivity,reveals气孔率,theperformancerelativedensityand容重determination andnationalstandardGB/T3299-1996 CeramicsfordailyuseWater-absorptivityDeterminationMethod centertotestequipmentrequest.二、主要技术指标1、容量： 250、 4002、真空度：0.1Mpa 0.005Mpa3、抽真空时间：0～99分钟连续可调4、注水时间：0～99分钟连续可调5、浸泡时间：1～120分钟连续可调6、电源：220V 180WSecond,maintechnicalspecification1,capacity:Phi250,phi4,002,vacuumdegree:0.1Mpa 0.005Mpa3,pullsoutthevacuumtime:0~99minutescontinuouslymayadjust4,pourwaterthetime:0~99minutescontinuouslymayadjust5,soakthetime:1~120minutescontinuouslymayadjust 6,thepowersource:220V180W 三、仪器的测试及组成该仪器采用机电一体化结构，由真空容器、水循环式真空泵、注水电磁阀、进气阀、排水阀、盛水器及数字式控制器组成。水循环真空泵具有运行噪音低，不易损坏，电耗低等特殊优点，使该仪器具有更优越的性能。Third,instrumenttestandcompositionThisinstrumentusestheintegrationofmachinerystructure,bythevacuumtank,thewatercycletypevacuumpump,pourswaterthesolenoidvalve,theadmissionvalve,thedraw-offvalve,ShengShuiqiandthedigitalcontrolleriscomposed.Thewatercyclevacuumpumphasthemovementnoiselowly,isnoteasytodamage,theelectricityconsumesandsoonlowlythespecialmerit,enablethisinstrumenttohaveamoresuperiorperformance.6th,powersource:220V180W 四、仪器的测试原理该仪器采用全自动数字化程序控制系统，无须操作机械人工进行抽水、排水、排气的操作过程。根据所采用的国家标准对吸水率测定方法、根据所需真空度技术要求设定好预抽真空时间（抽真空时间15－20分钟＋保持时间）、注水时间（20秒左右）、浸泡时间（日用陶瓷1小时，建筑卫生陶瓷10分钟）。当将已按测定方法制备好的试样烘至恒重后称重G，放入真空容器，关闭机器进气阀开关和排水阀开关，启动真空泵，通过真空泵对真空容器进行预抽真空，当真空度达到要求后，在此真空度下保持一定时间（日用陶瓷无此过程），保持时间到后，自动打开注水电磁阀，使其水徐徐注入真空容器中，直至水面满足要求时（可实际调整时间），自动关闭注水阀，然后浸泡一定时间，浸泡时间结束，声音自动报警，关闭电源开关。打开机器进气阀开关，对真空容器中注入空气，当真空表回零时，打开排水阀开关，将真空容器中的水放回水容器中，将真空容器盖揭去，取出试样，用已吸水饱和布揩去表面附着水，称重G1，然后计算：G1－G0W= 100%G0W 吸水率 （%）G0 试样干重量 （克）G0 试样吸水后重量 （克）Fourth,instrumenttestprinciple Thisinstrumentusestheentireautomaticdigitizedprocedurecontrolsystem,doesnotneedtooperatethemachineryartificiallytocarryonpumpswater,drainingwater,theexhaustoperatingprocess.Accordingtothenationalstandardwhichusestothewater-absorptivitydeterminationmethod,thebasisneedsthevacuumdegreespecificationtoestablishthegood预抽真空time(topulloutvacuumtime15-20minutes+maintenancestime),pourswaterthetime(about20seconds),soaksthetime(ceramicsfordailyuse1hour,constructionsanitaryearthenware10minutes).AfterhasarrangedaccordingtothedeterminationmethodsystemthetestspecimendriestotheconstantweightcalledheavyG,putsinthevacuumtank,theshut-downadmissionvalveswitchandthedraw-offvalveswitch,startsthevacuumpump,carriesonthroughthevacuumpumptothevacuumtank预抽真空,afterthevacuumdegreeachievedtherequest,maintainsthecertaintimeunderthisvacuumdegree(ceramicsfordailyusenottohavethisprocess),themaintenancetimetoafter,automaticallyopenspourswaterthesolenoidvalve,causesitswaterslowlytopourintointhevacuumtank,whenthewatersurfaceanswersthepurpose(mayactualtime),theautomaticshut-offnotewatervalve,thensoakthecertaintime,soaksthetimetofinish,soundauto-alarm,closesthepowerswitch.Turnsonthemachineadmissionvalveswitch,poursintotheairtothevacuumtankin,whenthevacuumgaugereturnstothezerohour,turnsonthedraw-offvalveswitch,putsthevacuumtankinwaterinthebackwatervessel,uncoversthevacuumtanklid,takesoutthetestspecimen,withhasabsorbnwaterthesaturatedclothtowipethesuperficialattachedwater,callsheavyG1,thencomputation: G1－G0 W= 100%G0W 吸水率 （%） Water-absorptivity G0 试样干重量 （克） Thetestspecimendoestheweight G0 试样吸水后重量 （克） Aftertestspecimenabsoringwaterweight
