pc‖原料：聚---pc‖1010nh是一款高强度透明pc‖材料，是产品在透明产品设计时所选用的一款常用材料，常被注塑成各式各样的透明或者半透明制件，可应用于汽车车灯等部件。a、原材料受潮————干燥原料
pc material: polycarbonate pc 1010nh is a high strength transparent pc material. it is a common material used by product engineers in the design of transparent products. it is often injected into all kinds of transparent/translucent parts, which can be used in car lights&other parts. a&raw materials are dampened - dry raw materials
??b、排气---————改进模具设计
poor b&poor exhaust gas -- improving mold design
??3、树脂变色、黑点
resin 3, resin discoloration, black spot
??a、料筒、喷嘴积料————清理料筒和喷嘴
a, cylinder&nozzle material - cleaning cylinder&nozzle.
??b、成型温度过高————降低成型温度
b, forming temperature too high -- reducing molding temperature
??4、制品未充满

??a、物料塑化不够————提高料筒温度
a, material is not plasticized -- increasing the barrel temperature.
??b、模具温度过低————提高模具温度
b, mold temperature is too low -- improve mold temperature
??c、喷嘴溢料————调整模具位置
c, nozzle overflow - adjust the position of the die.
pom☆原料可在-40℃～100℃温度范围内长期使用。pom☆极易分解，分解温度为280℃，分解时有性和腐蚀性气体发生。故模具钢材宜选用耐腐蚀性的材料制作。力学性能pom☆强度、刚度高，弹性好，减磨耐磨性好。eva 2803geva 2803glcp s625pa/mxd6.1022h(2)pom gt525tpv.251-85w232pa66/pa350m4ppa/4000tpu/11t75dcoc 8007s-04pa66 s223-pg2utpx/rt31xbpcta z6002ppa/51g35hslpp hd905cfpc dmx1435pbt rs1409pom.m270ppˉj801pa66.st801hs1lpa46.te250f3poms9244xap2 pom 马来西亚宝理 gh-25dpom ckx-5623pom m90-07pp/cortecm-121/pa46/tw241f10pmma.lp-3105(粉pps r-4tpu/58630lcp.t130pom s9064tpee.1140lhf pps日本宝理1130a1pc l1250tpc/2807mas167pom.3013aeva1533pps.a604 pp 4160
pom material can be used for a long time in the range of -40 to 100 c. pom is easy to deco-e, deco-ition temperature is 280 degrees,&there are excitant&corrosive gases in deco-ition. therefore, die steel should be made of corrosion-resistant material. the mechanical properties are pom, high strength, high rigidity, good elasticity, good abrasion resistance.
pbt聚对---丁二醇酯，又名聚对---四次酯。英文名；polybutyleneterephthalate。简称pbt pbtp或ptmt，它是对---与1,4-丁二醇的缩聚物。可由酯交换法或直接脂化法经缩聚而制得，今后的发展趋势为直接酯化法生产。pbt和pet一起被称为热塑性聚酯。
pbt poly (butylene terephthalate), also known as terephthalic acid, four methyl ester. english name; polybutyleneterephthalate. referred to as pbt pbtp/ptmt, it is a polycondensation of benzoic acid&1,4- butanediol. it can be prepared by transesterification/direct esterification by condensation. the development trend in the future is direct esterification. pbt&pet are called thermoplastic polyester together.eva 2803geva 2803gpbtˉhf-5008pa6ˉbm7300thspcˉ950pc vr2000pp ep648pc/dfl23 pvc德国e67stabs 4000pgpa12/lkn-5hpp/ep310dpp/cpc04cpps 646---62tpeˉ1045nm|1002pom n2650z6pp j340pcˉ3262rtpv 121-87 poe韩国lglc175eva/h401144pp.bx3920pc/fl913pp h4120pa6 8267ghsaeea/271---ctpv 3400bpp 5752 pp/h1850tpe hx8iczpc slx2071tpp c1608pom.gf705pcˉ134 pp台塑1124htpu.70aipp fh44neva 1533tpv 2673bpom/5010/
