Hloov kho cov yas PC + ABS, cov khoom siv engineering ua los ntawm alloying lossis blending polycarbonate (PC) thiab acrylonitrile-butadiene-styrene copolymer (ABS), muaj cov khoom siv logistics uas tsis tsuas yog cuam tshuam rau lub cev ruaj khov ntawm cov khoom siv raw thiab cov khoom tiav thaum khaws cia thiab thauj khoom, tab sis kuj cuam tshuam ncaj qha rau cov saw hlau efficiency thiab kev ruaj ntseg zoo ntawm cov khoom kawg. Hauv kev tsim khoom thoob ntiaj teb thiab kev faib khoom, kev nkag siab zoo thiab kev ua kom zoo ntawm kev xa khoom ntawm PC + ABS yog qhov tseem ceeb rau kev txo qis, tswj cov nqi, thiab ua kom cov khoom zoo ib yam.
Los ntawm lub cev thiab cov khoom siv logistics pom, PC + ABS muaj qhov ntom ntom ntawm kwv yees li 1.1-1.2 g / cm³, faib nws raws li lub teeb yuag engineering yas, uas pab txo qis kev thauj mus los thiab kev siv zog thauj khoom. Nws lub zog tensile ntawm chav tsev kub tseem nyob ntawm 50-65 MPa, thiab nws qhov kev cuam tshuam lub zog yog 20-40 kJ / m², nthuav tawm qhov ua haujlwm zoo rau kev cuam tshuam thiab kev sib tsoo. Nws tuaj yeem tswj hwm kev ncaj ncees raws li cov khoom lag luam thiab thaj av / hiav txwv kev thauj mus los, txo qhov kev pheej hmoo ntawm kev tawg thiab deformation los ntawm kev poob los yog compression. Txawm li cas los xij, PC Cheebtsam yog rhiab heev rau kev txiav; punctures los ntawm cov khoom ntse lossis tee los ntawm qhov siab tseem tuaj yeem ua rau thaj tsam tawg. Yog li ntawd, cov ntaub ntawv cushioning thiab tiv thaiv kev sib tsoo thav ntawv yuav tsum tau siv rau hauv kev thauj khoom ntim tsim kom tsis txhob muaj cov khoom hnyav tiv thaiv cov npoo ntse.
The thermal and humidity-related logistical properties are also critical. PC+ABS has a heat distortion temperature between 110-130℃ and is dimensionally stable under normal storage temperatures (≤35℃). However, prolonged exposure to high temperatures (>50 degree) los yog lub hnub ci ncaj qha tuaj yeem ua rau thermal aging, ua rau txo qis kev cuam tshuam lub zog thiab qhov muag daj. Tsis tas li ntawd, PC yog hygroscopic; Yog tias cov dej noo ntawm cov khoom siv raw khoom ntau tshaj 0.02%, qhov tsis xws luag xws li nyiaj streaks thiab npuas yuav tshwm sim thaum ua tom ntej. Yog li ntawd, ib puag ncig qhuav yuav tsum tau khaws cia thaum lub sij hawm thauj khoom thiab chaw khaws khoom, siv cov khoom siv ya raws - pov thawj ntim thiab ntim ntim, thiab ua cov ntsuas dej noo ua ntej warehouses. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tswj cov av noo nyob rau hauv cov thawv thaum lub sij hawm thauj khoom hiav txwv los yog caij los nag, nrog rau cov khoom siv desiccants thiab ntsuas kub ntsuas raws li qhov tsim nyog.
Hais txog cov tshuaj tiv thaiv, PC + ABS nthuav tawm zoo tiv thaiv dej, tsis muaj zog acids thiab alkalis, thiab cov roj sib xyaw, tiv thaiv cov tshuaj lom neeg hauv kev lag luam thauj ib puag ncig. Txawm li cas los xij, nws tsis tiv taus cov kuab tshuaj muaj zog (xws li aromatics, ketones, thiab chlorinated solvents). Kev sib cuag nrog cov tshuaj no yuav ua rau o, tawg, lossis kev ua haujlwm tsis zoo. Yog li ntawd, thaum lub sij hawm logistics, cov tshuaj incompatible yuav tsum tau nruj me ntsis cais, thiab kev tiv thaiv to thiab zoned loading tswv yim yuav tsum tau saws.
Lub flowability ntawm cov txheej txheem granules kuj xav tau kev saib xyuas. PC + ABS cov khoom yuav tsum tsis sib xws hauv cov duab, tsis muaj plua plav thiab ntev, cov duab tsis zoo, tiv thaiv kev sib tsoo lossis ntsuas qhov yuam kev thaum tsis siv neeg ntsuas thiab xa khoom. Kev sib txhuam hnyav thiab siab shear yuav tsum raug zam thaum lub sij hawm thauj mus los thiab tuav kom tsis txhob ua ntej - melting adhesion ntawm cov khoom vim hluav taws xob zoo li qub lossis cov khoom siv hluav taws xob sib xyaw ua ke, uas yuav cuam tshuam rau kev sib xyaw ua ke thiab molding zoo.
Hauv cov ntsiab lus, hloov kho PC + ABS yas nthuav tawm qhov zoo hauv kev xa khoom, suav nrog lub teeb yuag, kev ua haujlwm zoo, huab cua tsis zoo, thiab tshuaj lom neeg. Txawm li cas los xij, nws qhov rhiab heev rau qhov kub thiab av noo ib puag ncig, kev cuam tshuam rau txhua yam, thiab cov tshuaj tsis sib xws yuav tsum tau tsom xyuas kev tiv thaiv hauv kev ntim khoom, khaws cia, thiab kev thauj mus los. Los ntawm kev siv cov tswv yim tswj kev thauj khoom xws li ya raws- pov thawj thiab qhov kub thiab txias- tswj, buffering thiab tiv thaiv - kev sib tsoo, thiab kev sib cais thiab kev tiv thaiv, kev ua haujlwm zoo sib xws tuaj yeem tswj tau zoo, ua kom muaj kev tswj hwm zoo thiab kev ua kom zoo tshaj plaws thoob plaws hauv tag nrho cov saw hlau los ntawm cov khoom siv raw khoom mus rau qhov kawg kev tsim khoom, thiab muab kev ruaj ntseg logistics xws li kev txhawb nqa 6. tsheb, electronics, thiab khoom siv hauv tsev.
