ABS appearance is not lit was Ivory aggregates, the product can be riotous with colour and form, has high gloss. ABS relative density of about 1.05, low water absorption rate. ABS and other data connectivity, easy external printing, coating and coating disposed of. ABS oxygen index of 18~ 20, belong to flammable polymers, the flame was yellow, with black smoke, and announced the extraordinary cinnamon.
Mechanical function
ABS has excellent mechanical function, its impact strength is excellent, can at very low temperatures using; ABS abrasion resistance excellent, good size invariance, and has oil resistance, can be used in medium load and speed of bearing. ABS creep resistance than PSF and PC, but the ratio of PA and POM small. The bending strength and compression strength of ABS is poor plastic. ABS mechanical function affected by temperature larger.
Thermodynamic function
ABS heat distortion temperature of 93~ 118, finished product after annealing treatment can also be progress of about 10 DEG c.. ABS at - 40 degrees C can still show a certain toughness, in - 40~ 100DEG C within the scope of use.

CEVIAN SERG2 ABS缺口冲击强度 注塑工艺:
注塑工艺:CEVIAN SERG2 ABS缺口冲击强度
注塑成型(Injection Molding)受热消融的资料由高压射入模腔,经冷却固化后,获得成形品的办法。该办法合用于外形复杂部件的批量出产,是主要的加工办法之一。
注塑成型是以下列六大挨次执行:合模 ,射出, 保压, 冷却, 开模 ,掏出产物 ,反复执行这种功课流程,就可延续出产成品。
注塑工艺要思索的7个要素
一、缩短率
热塑性塑料成型缩短的方式及核算如前所述,影响热塑性塑料成型缩短的要素如下:
1.1塑料种类热塑性塑料成型进程中因为还存在结晶化形起的体积转变,内应力强,冻住在塑件内的剩余应力大,分子取向性强等要素,因而与热固性塑料比拟则缩短率较大,缩短率局限宽、偏向性分明,别的成型后的缩短、退火或调湿处置后的缩短率普通也都比热固性塑料大。
1.2塑件特征成型时熔融料与型腔外表接触外层立刻冷却构成低密度的固态外壳。因为塑料的导热性差,使塑件内层迟缓冷却而构成缩短大的高密度固态层。所以壁厚、冷却慢、高密度层厚的则缩短大。别的,有无嵌件及嵌件结构、数目都直接影响料流偏向,密度散布及缩短阻力巨细等,所以塑件的特征对缩短巨细、偏向性影响较大。
1.3进料口方式、尺寸、散布这些要素直接影响料流偏向、密度散布、保压补缩效果及成型工夫。直接进料口、进料口截面大(尤其截面较厚的)则缩短小但偏向性大,进料口宽及长度短的则偏向性小。距进料口近的或与料流偏向平行的则缩短大。
1.4成型前提模具温度高,熔融料冷却慢、密度高、缩短大,尤其对结晶料则因结晶度高,体积转变大,故缩短更大。模温散布与塑件表里冷却及密度平均性也有关,直接影 响到各局部缩短量巨细及偏向性。别的,坚持压力实时间对缩短也影响较大,压力大、工夫长的则缩短小但偏向性大。注塑压力高,熔融料粘度差小,层间剪切应力小,脱模后弹性 回跳大,故缩短也可过量的减小,料温高、缩短大,但偏向性小。因而在成型时调整模温、压力、注塑速度及冷却工夫等诸要素也可恰当改动塑件缩短状况。
模具设计时依据各类塑料的缩短局限,塑件壁厚、外形,进料口方式尺寸及散布状况,按经历确定塑件各部位的缩短率,再来核算型腔尺寸。对高精度塑件及难以把握缩短率时,普通宜用如下办法设计模具:
①对塑件外径取较小缩短率,内径取较大缩短率,以留有试模后批改的余地。
②试模确定浇注系统方式、尺寸及成型前提。
③要后处置的塑件经后处置确定尺寸转变状况(测量时必需在脱模后24小时今后)。
④按实践缩短状况批改模具。
⑤再试模并可恰当地改动工艺前提稍微批改缩短值以知足塑件要求。
CEVIAN SERG2 ABS缺口冲击强度 成型工艺:
ABS同PS一样是一种加工功能优秀的热塑性塑料,可用通用的加工办法加工。
ABS的熔体活动性比PVC和PC好,但比PE、PA及PS差,与POM和HIPS相似;ABS的活动特征属非牛顿流体;其熔体粘度与加工温度和剪切速度都有关系,但对剪切速度更为敏感。
ABS的热不变性好,不易呈现降解景象。ABS的吸水率较高,加工前应进行枯燥处置。普通成品的枯燥前提为温度80~85℃,工夫2~4h;对非凡要求的成品(如电镀)的枯燥前提为温度70~80℃,工夫18~18h。ABS成品在加工中易发生内应力,内应力的巨细可经过浸入冰乙酸中查验;如应力太大和成品对应力开裂绝对制止,应进行退火处置,详细前提为放于70~80℃的热风轮回枯燥箱内2~4h,再冷却至室温即可。
ABS with PS as a processing functions excellent thermoplasticprocessing methods and processing available generic.ABS melt activity than PVC and PC, but better than PE, PA and PS, POM and HIPS; activity characteristics of ABS is a non-Newtonian fluid; melt viscosity and processing temperature andshear rate has relationship, but more sensitive to shear rate.
ABS thermal invariance, is not easy to show degradation of sight.ABS higher water absorption, processing should be carried outbefore the dry disposal. Ordinary finished boring premise for thetemperature 80 ~ 85 ℃, work 2 ~ 4h; extraordinary requirements of the finished product, such as electroplating, boring premise fora temperature of 70 ~ 80 ℃, work 18 ~ 18h. ABS finishedprocessing prone to internal stress, internal stress of big and small can be immersed in glacial acetic acid in the inspectionshould be carried out; such as stress too much and finishedabsolutely to stop the stress cracking, annealing disposaldetailed premise put in 70 to 80 ° C hot air cycle boring box 2 ~4h, then cooled to room temperature can be.
