Hauv kev ua cov saw hlau ntawm engineering plastics thiab tshwj xeeb plastics, yas granules yog ib qho tseem ceeb hauv nruab nrab daim ntawv txuas cov khoom siv raw thiab cov khoom kawg. Lawv yog tsim los ntawm kev sib xyaw, melting, thiab extruding resin matrices, kev ua haujlwm ua haujlwm, thiab ntau yam khoom ntxiv, yooj yim rau kev thauj mus los thiab kev ntsuas, thiab tsim nyog rau kev ua haujlwm ncaj qha hauv kev txhaj tshuaj molding thiab extrusion tshuab. Yog li-hu ua "cov khoom lag luam yas muaj zog hauv Shanghai" feem ntau yog xa mus rau cov chaw tsim khoom yas hloov kho uas tsis yog tsuas yog muaj peev xwm ua tau zoo li qub tab sis kuj tsim cov qauv tsim thiab ua kom zoo dua qub raws li kev thov. Tus nqi tseem ceeb ntawm cov tuam txhab lag luam no yog nyob rau hauv kev hloov pauv cov khoom siv hauv chaw kuaj mob rau hauv huab hwm coj- cov khoom lag luam granule, muab cov neeg siv khoom hauv qab nrog cov khoom tsim tawm.
Los ntawm cov khoom siv kev pom, hloov cov yas granules npog ntau yam. Kev hloov kho cov yas yas xws li nylon, polycarbonate, polyoxymethylene, thiab polyester; Cov kev hloov kho yas tshwj xeeb suav nrog siab - kub resistant lossis tshuaj lom neeg heev - cov ntaub ntawv tiv taus xws li polyetheretherketone, polysulfone, thiab kua siv lead ua polymers. Tsis tas li ntawd, muaj kev hloov pauv ntawm cov yas alloy, thermoplastic elastomers, thiab fluoroplastics, thiab lwm yam. Cov substrates sib txawv txiav txim siab qhov kev ua tau zoo ciam teb ntawm cov yas granules, thaum kev hloov kho tshuab yog lub luag haujlwm rau nthuav cov ciam teb no. Piv txwv li, ntxiv cov nplaim hluav taws tuaj yeem txhim kho hluav taws kub, qhia cov khoom siv hluav taws xob tuaj yeem ua tiav electromagnetic shielding, txhawb nqa nrog iav fiber lossis carbon fiber tuaj yeem txhim kho rigidity thiab lub zog, thiab ntxiv lubricants los yog nanofillers tuaj yeem txhim kho tribological zog.
Ntawm ntau yam kev hloov kho thev naus laus zis, tus ntoo khaub lig- txuas thiab sib xyaw ntawm nanomaterials thiab resins tau dhau los ua ib qho kev taw qhia tseem ceeb hauv xyoo tas los no. Kev hnav tsoos tsho- kev hloov kho tiv thaiv feem ntau tso siab rau kev ntxiv cov roj nplua nyeem xws li polytetrafluoroethylene, graphite, molybdenum disulfide, lossis silicone roj. Cov additives no txo qhov hnav los ntawm kev tsim cov yeeb yaj kiab hloov chaw ntawm kev sib txhuam, tab sis lawv ua rau tsis ua hauj lwm nyob rau hauv siab loads thiab kub. Nano- hloov kho yuav siv txoj hauv kev sib txawv. Nws siv tshwj xeeb kho nanoparticles kom dhau ib tug ntoo khaub lig- txuas cov tshuaj tiv thaiv nrog resin macromolecules nyob rau hauv ib tug siab -kub molten lub xeev, tsim ib tug muaj zog tshuaj los yog lub cev daim ntawv cog lus ntawm inorganic hais thiab cov organic theem. Nyob rau hauv txoj kev no, nanoparticles tsis yog ib qho yooj yim dispersed theem, tab sis yog kev koom ua ke nrog cov resin matrix, yog li hloov cov kev sib txhuam ntawm cov khoom nto ntawm lub molecular nplai thiab systematically txhim kho hnav tsis kam. Cov cuab yeej no tshwj xeeb tshaj yog muaj txiaj ntsig rau kev txav mus los xws li lub zog, bearings, thiab sliders.
Carbon fiber reinforcement yog lwm tus neeg sawv cev siab -kev hloov kho txoj kev. Cov carbon fibers luv thiab ntev tuaj yeem muab sib xyaw rau hauv cov thermoplastic resins nyob rau hauv sib txawv proportions, thiab shear dispersion thiab impregnation txheej yog tiav los ntawm ib tug ntxaib - ntsia hlau extruder. Compared with unreinforced plastics, carbon fiber reinforced plastics show improvements in tensile strength, flexural modulus, and creep resistance, while the increase in density is limited, thus facilitating lightweighting. Cov ntaub ntawv no tuaj yeem hloov qee yam tsis yog- cov khoom siv hlau lossis txhuas alloy thiab tau siv dav hauv cov khoom siv drone, cov khoom siv neeg hlau, cov khoom siv tsheb, thiab cov khoom ua si. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev ua tau zoo ntawm carbon fiber reinforced plastics tsis yog nyob ntawm cov ntsiab lus ntawm cov pa roj carbon fiber ntau xwb tab sis kuj tseem nyob ntawm qhov ntev ntawm cov fiber ntau, kev sib txuas ntawm kev sib txuas zoo, thiab cov txheej txheem molding.
