Mawu Oyamba
ABS (Acrylonitrile Butadiene Styrene) ndi imodzi mwa thermoplastics yotchuka yomwe imagwiritsidwa ntchito popanga jekeseni. Imadziwika chifukwa cha mphamvu zake, kulimba mtima, komanso kusinthasintha, ndikupangitsa kuti ikhale yoyenera pazigawo zamagalimoto, zamagetsi ogula, komanso kugwiritsa ntchito mafakitale. Komabe, monga zida zilizonse, ABS imabwera ndi zovuta zake panthawi yopangira jakisoni. Kumvetsetsa nkhanizi—ndi momwe mungazithetsere—kungathandize opanga kukonza bwino zinthu, kuchepetsa zolakwika, ndi kuonetsetsa kuti zinthu zikuyenda bwino.
Kuwotcha ndi kuchepa
Chimodzi mwazovuta zomwe zimachitika kwambiri pakuumba jekeseni wa ABS ndikupukutira kapena kuchepa kosagwirizana. Izi zimachitika pamene madera osiyanasiyana a gawolo azizira mosiyanasiyana, zomwe zimapangitsa kuti pakhale zolakwika.
Yankho: Gwiritsani ntchito mawonekedwe oyenera a nkhungu okhala ndi makulidwe a khoma lofanana, sinthani kuzizirira, ndikuwongolera kutentha kwa nkhungu. Kuthamanga kwapang'onopang'ono kumathandizanso kuchepetsa kuchepa ndikuwonetsetsa kukhazikika kwa gawo.
Zowonongeka Pamwamba
Zigawo za ABS nthawi zambiri zimasankhidwa kuti zitheke bwino, koma nkhani zapamtunda monga zolembera, mizere yowotcherera, kapena mizere yoyenda zimatha kukhudza mawonekedwe ndi magwiridwe antchito.
Yankho: Kuchepetsa kuwonongeka kwapamtunda, sungani kutentha kosasunthika, onetsetsani kuti zipata zimayikidwa bwino, ndipo gwiritsani ntchito kupukuta nkhungu pakafunika kutero. Kutulutsa mpweya kungathenso kuchotsa mpweya wotsekeka umene umayambitsa zilema.
Chinyezi Sensitivity
ABS ndi hygroscopic, kutanthauza kuti imatenga chinyezi kuchokera mumlengalenga. Ngati sichiwumitsidwa bwino musanawumbe, chinyezi chingayambitse thovu, splay, kapena kusalimba kwa makina.
Yankho: Nthawi zonse zowuma utomoni wa ABS pa kutentha kovomerezeka (nthawi zambiri 80-90 ° C kwa maola 2-4) musanakonze. Gwiritsani ntchito zida zomata kuti musunge utomoni kuti musamayamwidwe ndi chinyezi.
Kutentha Kwambiri kwa Mold Kutentha
ABS imafuna kuwongolera bwino kutentha. Ngati nkhungu kapena mbiya kutentha kwambiri, kungayambitse kuwonongeka ndi kusinthika. Ngati zotsika kwambiri, zimatha kuyambitsa kudzaza kosakwanira kapena kumamatira koyipa.
Yankho: Sungani kutentha kwa nkhungu mokhazikika mkati mwawindo lovomerezeka lokonzekera. Makina owunikira okha amatha kutsimikizira kusasinthika panthawi yopanga.
Kulondola kwa Dimensional
Chifukwa ABS imagwiritsidwa ntchito kwambiri pazinthu zomwe zimafuna kulolerana kolimba, kusunga kulondola kwazithunzi kumatha kukhala kovuta. Kusiyanasiyana kwa kukakamiza, kutentha, kapena kutuluka kwa zinthu kungayambitse mbali zina zachilendo.
Yankho: Gwiritsani ntchito njira zasayansi zowumba monga kuwunika kwapang'onopang'ono, ndikuwonetsetsa kuti zida za nkhungu zimasungidwa bwino. Gwiritsani ntchito zoyerekeza za CAE (zothandizira makompyuta) panthawi ya mapangidwe kuti mulosere kutsika komwe kungachitike.
Environmental Stress cracking
ABS imatha kukhudzidwa ndi mankhwala ena, mafuta, kapena kupsinjika kosalekeza, zomwe zimapangitsa kuti pakhale ming'alu pakapita nthawi.
Yankho: Sinthani kapangidwe ka gawo kuti muchepetse kupsinjika, gwiritsani ntchito ma ABS osakanikirana ndi kukana kwakukulu, ndikuwonetsetsa kuti ikugwirizana ndi malo omwe mukufuna.
Mapeto
Kupanga jakisoni wa ABS kumapereka mwayi wabwino wopanga magawo olimba, osunthika, koma zovuta monga kumenyera, kuyamwa kwa chinyezi, ndi zolakwika zapamtunda ziyenera kuyang'aniridwa mosamala. Potengera njira zabwino kwambiri monga kukonzekera bwino kwa zinthu, kapangidwe ka nkhungu kokometsedwa, komanso kuwongolera kutentha kwanthawi zonse, opanga amatha kuthana ndi mavutowa ndikupeza zotsatira zapamwamba komanso zokhazikika.
