Muaj ntau txhiab tus plastics nyob rau hauv kev ua lag luam rau kev tsim kho sai lossis kev tsim khoom me me - xaiv cov yas zoo rau ib txoj haujlwm tshwj xeeb tuaj yeem nyuaj, tshwj xeeb tshaj yog rau cov neeg tsim khoom lag luam lossis cov neeg ua lag luam uas xav tau. Txhua yam khoom sawv cev rau kev sib haum xeeb ntawm tus nqi, lub zog, yoog raws thiab qhov chaw tiav. Nws yog ib qho tsim nyog yuav tsum xav txog tsis yog tsuas yog daim ntawv thov ntawm ib feem lossis cov khoom, tab sis kuj yog ib puag ncig uas nws yuav siv.
Feem ntau, engineering plastics tau txhim kho cov khoom siv kho tshuab uas muab kev ruaj khov dua thiab tsis hloov thaum lub sijhawm tsim khoom. Qee hom yas kuj tuaj yeem hloov kho los txhim kho lawv lub zog, nrog rau kev cuam tshuam thiab kub ua haujlwm. Cia peb dhia mus rau hauv cov khoom siv yas sib txawv los txiav txim siab nyob ntawm qhov ua haujlwm ntawm qhov kawg lossis cov khoom.
Ib qho ntawm cov khoom siv feem ntau siv los ua cov khoom siv kho tshuab yog nylon, tseem hu ua polyamide (PA). Thaum polyamide yog tov nrog molybdenum, nws muaj ib tug du nto rau yooj yim txav. Txawm li cas los xij, nylon-on-nylon iav tsis pom zoo vim, zoo li cov yas, lawv nyiam ua ke. PA muaj qhov hnav thiab ua kom tsis zoo, thiab cov khoom siv kho kom zoo ntawm qhov kub thiab txias. Nylon yog cov khoom siv zoo tshaj plaws rau 3D luam ntawv nrog yas, tab sis nws nqus dej dhau sijhawm.
Polyoxymethylene (POM) kuj yog ib qho kev xaiv zoo heev rau cov khoom siv kho tshuab. POM yog cov khoom siv acetal siv los ua DuPont's Delrin, cov yas muaj txiaj ntsig siv hauv cov iav, cov ntsia hlau, lub log thiab lwm yam. POM muaj siab flexural thiab tensile lub zog, rigidity thiab hardness. Txawm li cas los xij, POM yog degraded los ntawm alkali, chlorine thiab dej kub, thiab nws yog ib qho nyuaj rau ua ke.
Yog tias koj qhov project yog qee yam ntim, polypropylene (PP) yog qhov kev xaiv zoo tshaj plaws. Polypropylene yog siv rau hauv cov thawv ntim khoom noj vim tias nws tiv taus cua sov, tsis muaj roj thiab cov kuab tshuaj, thiab tsis tso cov tshuaj, ua rau nws muaj kev nyab xeeb noj. Polypropylene kuj tseem muaj qhov sib npaug zoo ntawm qhov tawv thiab qhov cuam tshuam lub zog, ua rau nws yooj yim los ua cov loops uas tuaj yeem khoov duav tsis tau tawg. Nws kuj tseem siv tau rau hauv cov kav dej thiab hoses.
Lwm qhov kev xaiv yog polyethylene (PE). PE yog cov yas ntau tshaj plaws nyob hauv lub ntiaj teb uas tsis tshua muaj zog, hardness thiab nruj. Nws feem ntau yog cov yas dawb uas siv los ua cov tshuaj fwj, mis nyuj thiab tshuaj ntxuav tais diav. Polyethylene yog cov resistant rau ntau yam tshuaj, tab sis muaj ib tug tsawg melting point.
Cov khoom siv Acrylonitrile butadiene styrene (ABS) yog qhov zoo tagnrho rau txhua qhov haujlwm uas yuav tsum muaj kev tiv thaiv siab thiab tsim kua muag thiab tawg tsis kam. ABS yog lub teeb yuag thiab tuaj yeem txhawb nqa nrog fiberglass. Nws yog kim tshaj li styrene, tab sis kav ntev dua vim nws hardness thiab lub zog. Fusion-molded ABS 3D qauv rau kev ua qauv sai.
Muab nws cov khoom, ABS yog qhov kev xaiv zoo rau cov khoom siv. Ntawm Star Rapid, peb tsim cov ntaub ntawv smartwatch rau E3design siv txhaj tshuaj molded dub pre-painted ABS / PC yas. Qhov kev xaiv ntawm cov khoom siv no ua rau tag nrho cov cuab yeej siv lub teeb, thaum tseem muab cov ntaub ntawv uas tuaj yeem tiv taus qee lub sijhawm, xws li thaum lub moos tsoo ib qho nyuaj. High impact polystyrene (HIPS) yog ib qho kev xaiv zoo yog tias koj xav tau cov khoom siv ntau yam thiab cuam tshuam. Cov khoom siv no yog tsim los ua cov cuab yeej siv hluav taws xob ruaj khov thiab cov cuab yeej cuab tam. Txawm hais tias HIPS pheej yig, lawv tsis suav tias yog ib puag ncig zoo.
Ntau qhov haujlwm hu rau kev txhaj tshuaj molding resins nrog elasticity zoo li roj hmab. Thermoplastic polyurethane (TPU) yog ib qho kev xaiv zoo vim nws muaj ntau yam tshwj xeeb formulations rau siab elasticity, tsis kub ua hauj lwm thiab kav ntev. TPU kuj tseem siv rau hauv cov cuab yeej hluav taws xob, cov menyuam, cov khoom siv hluav taws xob, thiab cov khoom ua si. Vim nws cov kuab tshuaj tiv thaiv, TPU muaj kev puas tsuaj thiab shear lub zog thiab tuaj yeem siv rau ntau qhov chaw ua haujlwm. Txawm li cas los xij, nws paub txog kev nqus dej noo los ntawm huab cua, ua rau nws nyuaj rau kev ua haujlwm thaum lub sijhawm tsim khoom. Rau kev txhaj tshuaj molding, muaj cov roj hmab thermoplastic (TPR), uas yog pheej yig thiab yooj yim los tuav, xws li ua rau poob siab-absorbing roj hmab grips.
Yog tias koj qhov yuav tsum tau lub qhov muag pom tseeb lossis qhov rais, acrylic (PMMA) yog qhov zoo tshaj. Vim nws cov rigidity thiab abrasion kuj, cov khoom no yog siv los ua shatterproof qhov rais xws li plexiglass. PMMA kuj polishes zoo, muaj zog tensile zoo, thiab yog tus nqi zoo rau kev ntim ntau lawm. Txawm li cas los xij, nws tsis yog qhov cuam tshuam lossis tshuaj tiv thaiv zoo li polycarbonate (PC).
Yog tias koj qhov project xav tau cov khoom siv zog, PC muaj zog dua PMMA thiab muaj cov khoom siv kho qhov muag zoo, ua rau nws yog qhov kev xaiv tsim nyog rau cov lo ntsiab muag thiab lub qhov rais tsis muaj phom. PC kuj tuaj yeem khoov thiab tsim ntawm chav tsev kub yam tsis muaj kev tawg. Qhov no muaj txiaj ntsig zoo rau kev tsim qauv vim nws tsis tas yuav cov cuab yeej pwm kim los tsim. PC yog kim dua li acrylic, thiab lub sijhawm ntev ntawm cov dej kub tuaj yeem tso cov tshuaj phem, yog li nws tsis ua raws li cov qauv kev nyab xeeb khoom noj. Vim nws qhov cuam tshuam thiab khawb tsis kam, PC yog qhov zoo tagnrho rau ntau yam kev siv. Ntawm Star Rapid, peb siv cov khoom siv no los ua vaj tsev rau Muller Commercial Solutions handheld terminals. Ib feem yog CNC machined los ntawm cov khoom thaiv ntawm PC; txij li thaum nws yuav tsum tau ua kom pob tshab, nws tau sanded los ntawm tes thiab chav polished.
Qhov no tsuas yog ib qho kev piav qhia luv luv ntawm qee qhov feem ntau siv plastics hauv kev tsim khoom. Feem ntau ntawm cov no tuaj yeem hloov kho nrog cov iav fiber ntau, UV stabilizers, lubricants lossis lwm yam resins kom ua tiav qee yam tshwj xeeb.
Gordon Stiles yog tus tsim thiab tus thawj tswj hwm ntawm Star Rapid, tus qauv tsim sai, cov cuab yeej ceev ceev thiab lub tuam txhab tsim khoom ntim tsawg. Raws li nws keeb kwm engineering, Stiles tau tsim Star Rapid hauv 2005 thiab nyob rau hauv nws cov thawj coj lub tuam txhab tau loj hlob mus rau 250 tus neeg ua haujlwm. Star Rapid ntiav ib pab neeg thoob ntiaj teb ntawm engineers thiab cov kws tshaj lij uas sib txuas cov thev naus laus zis xws li 3D luam ntawv thiab CNC multi-axis machining nrog cov txheej txheem tsim khoom thiab cov qauv zoo. Ua ntej koom nrog Star Rapid, Styles muaj thiab ua haujlwm STYLES RPD, UK qhov loj tshaj plaws prototyping thiab tooling tuam txhab, uas tau muag rau ARRK Europe hauv 2000.
