viscous agent formulation and made as process
黏 combined agent good bad and powder quality and use amount very large powder fine degree, 蛋白质 and content effect/influence its property can. if powder in 蛋白质 and content high, fine degree low 于98目(100目筛 滤), make made as oxidation degree very high, material degree has 二十几秒( coating -4杯黏 degree amount ). 但存放5-7天 left right 会自然变稠, flow property, 呈胶冻状. use foam large, effect/influence bonding quality, use combined 格 淀 powder, need oxidation and 糊化程 degree 适当, made formed combined agent formed product degree 40±10秒, 贮存期 inner degree has large 变化, is color deep, degree basic 不变. powder use amount according to bonding for specific requirements 而改变, 如: 1, mono 面瓦楞纸 sheet/plate use bonding agent 覆面, for bonding agent requirements relatively low, powder use amount: 150-170kg/吨 water. 2, high strong/high 瓦楞纸两面施胶, for bonding agent requirements relatively high, powder use amount 170-200kg/吨 water. 3, 普通瓦楞纸 and 草浆瓦楞纸两面施胶 and sheet/plate and sheet/plate composite/compounding, for bonding agent requirements comparison high, powder use amount 180-300kg/吨 water. 4, 自动贴面 machine and tube/pipe use 胶, for bonding agent has requirements, remove drying fast outer, also requirements bonding good, strong/high degree high, powder use amount: 200-350kg/吨 water. lower specific introduction viscous agent (熟胶) use raw materials and formulation: agent: industrial alkali (NaOH) has crystallization 状, rod 状, sheet/slice and 喊30%NaOH water solvent liquid, need pure degree combined 格, 任何状态 烧 alkali can use, alkali use amount add oxidation powder in 搅拌20 separation powder liquid is semi transparent is 止, alkali amount large, liquid flow property large, transparent property good, time long, 但瓦楞楞峰施胶 in alkali amount 也会随之 increase large, made formed 瓦楞纸箱容 easy 反黄, formed 瓦楞纸箱 surface ink color; alkali amount small, add 入20 separation rear, is white or white 糊状, transparent viscous, 应酌情 again add separation alkali solvent liquid, make its formed is semi transparent liquid, use alkali amount small bonding agent 糊化不 good, adhesion force 差, easy 变稠. alkali use amount from 实际观察, generally is powder 12% relatively is combined 适. oxidation agent: powder bonding agent in, commonly used oxidation agent has di oxygen water, chlorine acid 钠, high acid and other. high acid as oxidation agent, use amount easy 掌握, made formed powder bonding agent formed product quality stability, made formed powder bonding agent color is deep color or black. chlorine acid and di oxygen water as oxidation agent made 出 淀 powder bonding agent color 泽淡黄, chlorine acid made powder bonding agent in use process in quality unstable, separation understanding chlorine gas, make as 人员感 to 眼部不适; di oxygen water made formed powder bonding agent in use in generate a large amount of foam, 需投放 defoamer. another, chlorine acid in cationic light or high temperature lower easy separation understanding, reduce its chlorine content, in application in need 随时掌握 it content degree add large use amount. from use in analysis, use di oxygen water oxidation agent, quality stability, use amount small, cost low, reaction fast is used as oxidation agent 理想材 material. in made as cold made high strong/high fast dry powder bonding agent 时, oxidation reaction key/critical function, oxidation 适当( add alkali rear 20-40 separation degree is 60-80秒), powder solvent understanding property can improve/increase, formed film can force good, adhesion force strong/high; oxidation 不够, large separation degradation less, its property and powder property same, add alkali rear, very long time 都不变 dilute, 甚至出现搅不动 phenomenon ( add alkali reaction 40 separation above, degree high 于100秒), this add oxidation agent 进行二次 oxidation, oxidation degree, powder ring type structure 开链, degree low, 甚至失 bonding can force ( add alkali rear reaction 20 separation degree low 于40秒). therefore need especially attention/notes oxidation agent content, ratio use. oxidation process in temperature degree 也起一定 function, temperature degree high, oxidation fast, generally oxidation reaction 10-15 separation 钟, 春秋天 oxidation 15-20 separation 钟, oxidation reaction 30 separation left right, oxidation reaction time long, oxidation full, product quality stability, time long effect/influence production cycle. oxidation agent specific use amount powder 变化而改变, powder use amount small, oxidation agent use amount small, chlorine acid content (10%) use amount is powder 28%, di oxygen water content (27.5%)约 is powder 4%, high acid use amount is powder 2%. oxidation is 否适当 methods is; add alkali rear 搅拌20-40 separation 钟, its degree is 60秒 left right (夏天) is good. this formed product 存放2 small left right, degree is 50秒 left right rear stability in 40±10秒. another, gas temperature low, oxidation agent use amount 应适当 increase, gas temperature high, reaction fast, use amount decrease/reduce. strong/high solid catalytic agent (简称 drying agent ): cold made high strong/high fast dry series powder bonding agent difference its it bonding agent main/primary factors is in selection “ strong/high solid catalytic agent ”. strong/high solid catalytic agent is types salt type and has machine machine combined material polymerization reaction formed, in bonding agent production process in, need use use amount 适宜, not only add fast reaction speed degree, but also rear through polymer and gas in oxygen chemical reaction, very fast crystallization, also add fast bonding agent film speed degree, shrink short drying time, improve/increase sheet/plate strong/high degree. therefore bonding agent bonding speed degree (初 viscous, full viscous, bad fiber )均 ratio type powder improve/increase above. sheet/plate hardness high, degree good, strong/high solid catalytic agent use amount in bonding agent in water use amount low 于5kg起不 to has function, water use amount high 于15kg, bonding agent film fast, easy generate sheet/plate phenomenon. therefore need control ratio/proportion. positive commonly used amount standards is 6-12kg/吨 water. crosslinked agent: bonding agent rear add 入硼砂 or acid, it can make short oxidation powder its and 硼原子形 formed combined material, through this 不规则 crosslinked, formed structure, tool has crosslinked increase viscous function, has improve/increase viscous force and add fast drying speed degree, another also to anti anti and reaction function, use amount is more good, more make bonding agent flow property 变差呈胶冻状, difficult above 胶, 胶质发脆. less combined 不够, adhesion force 差, 引起瓦楞纸 sheet/plate and phenomenon. oxidation rear powder add alkali rear 搅拌20-40 separation 钟, degree is 60秒 left right, can 进一步 add solvent liquid, degree high ultra- 100秒, can add oxidation agent 进行二次 oxidation, stability rear degree is 50秒( generally 2-3 small 时), again add solvent liquid, low 于100秒, can stability 2 small rear add water dilute 至60秒 left right add solvent liquid. has content 11.32%, acid has content 17.48%, application in, acid use amount can ratio decrease/reduce 近1/3, use amount generally is powder 3-3.5%, acid use amount generally is powder 2-3%. defoamer: in production and use process in due to powder quality and reaction 不适当, generate many foam, effect/influence water machine positive 常施胶, especially is use di oxygen water as oxidation agent, more easy generate foam, this add amount defoamer 消泡. defoamer can selection silicon or acid 三丁脂, positive alcohol and other. use chlorine acid or high acid as oxidation agent, acid 三丁脂 use amount is amount 0.01-0.03%, use di oxygen water as oxidation agent acid 三丁脂 use amount is amount 0.03-0.05%. especially attention/notes is defoamer use amount more, amount make bonding agent surface force reduce, viscous property, bonding strong/high degree to requirements, in production in, water machine upper foam more, most good machine water add less defoamer uniform, machine use, foam also more, again add less 许, can positive 常运转, has 一点, 千万不 need upper 边胶辊 in add defoamer, 以免出现甩胶 phenomenon. method defoamer is 否适当 can will powder 胶装一 transparent degree high bottle in, make 劲摇动约2 separation 钟, 立即停止, bottle in liquid upper foam, 如20-30秒 inner liquid upper large foam 消失, 即说明 defoamer use amount can, can upper use; 如20-30秒 inner, liquid in small 泡也消失, 则说明 use amount large, can reduce.
