Mapangidwe a nkhungu ya pulasitiki ndi ukadaulo wopanga

Pulasitiki nkhungu imakhudza kwambiri pokonza zinthu zapulasitiki.Ndipo nkhungu kapangidwe mlingo ndi mphamvu kupanga limasonyezanso dziko mlingo mafakitale, m'zaka zaposachedwapa chitukuko cha kupanga nkhungu pulasitiki akamaumba ndi mlingo mofulumira kwambiri, dzuwa, zochita zokha, lalikulu, mwatsatanetsatane, moyo wautali wa nkhungu pansi pa gawo ndi mochulukira lalikulu kuchokera kamangidwe nkhungu, processing njira, processing zida, mankhwala pamwamba ndi zina zotero zinthu zingapo mwachidule chitukuko cha nkhungu.
Njira yopangira pulasitiki ndi kapangidwe ka nkhungu
Kukonzekera kwa gasi, kupangidwa kwa gasi si teknoloji yatsopano, koma m'zaka zaposachedwapa, zakhala zikuchitika mofulumira ndipo njira zina zatsopano zatulukira.Jekeseni wothandizidwa ndi gasi wothira ndi kubaya mtundu wamadzimadzi otenthedwa ndi kutentha kwapadera kusungunula pulasitiki kuchokera mujakisoniyo.The madzi ndi usavutike mtima ndi vaporized mu nkhungu patsekeke kuwonjezera, kupangitsa dzenje, ndi kukankhira kusungunula pamwamba pa nkhungu patsekeke.Njirayi ingagwiritsidwe ntchito papulasitiki iliyonse ya thermoplastic.Jekeseni wothandizidwa ndi mpweya wa vibration ndikugwiritsa ntchito mphamvu yogwedezeka ku pulasitiki kusungunula kudzera mu mpweya woponderezedwa wa chinthu chozungulira, kuti muwongolere kamangidwe kazinthuzo ndikuwongolera magwiridwe antchito a chinthucho.Opanga ena amasintha mpweya womwe umagwiritsidwa ntchito popangira gasi kukhala zinthu zocheperako, ndipo amatha kupanganso zinthu zazikulu zopanda kanthu zokhala ndi mtengo wapamwamba komanso wotsika mtengo, koma mfundo yofunika ndikutuluka kwamadzi.
Kankhira ndi kukoka nkhungu, njira ziwiri kapena zingapo zimayikidwa mozungulira nkhungu ndikulumikizidwa ndi zida ziwiri kapena kupitilira apo kapena ma pistoni obwereza.Akamaliza jekeseni, wononga kapena pisitoni ya jekeseniyo imasuntha chammbuyo ndi mtsogolo kukankhira ndi kukoka zosungunulira mu nkhungu zisanayambe kusungunuka.Ukadaulowu umatchedwa ukadaulo wowongolera kuthamanga kwamphamvu, womwe umafuna kupewa vuto la kuchepa kwakukulu pamene zinthu zokhuthala zimawumbidwa ndi njira zachikhalidwe zoumba, Kuthamanga kwambiri kumapanga zinthu zoonda kwambiri.Zogulitsa za zipolopolo zowonda nthawi zambiri zimakhala zokhala ndi chiŵerengero cha nthawi yayitali.Ambiri aiwo amagwiritsa ntchito mitundu ingapo ya zipata.Komabe, kutsanulira kwazinthu zambiri kumayambitsa kuwotcherera, zomwe zingakhudze mawonekedwe azinthu zina zowonekera.Single mfundo kuthira si kophweka kudzaza nkhungu patsekeke, kotero iwo akhoza kupangidwa ndi mkulu kuthamanga kupanga luso.Mwachitsanzo, US Air Force, F16 fighter cockpit amapangidwa ndi luso limeneli, amene wakhala ntchito kupanga PC galimoto windscreens, The jekeseni kuthamanga akamaumba mkulu-anzanu zambiri kuposa 200MPA, choncho nkhungu ayenera kusankha mphamvu mkulu. ndi kulimba ndi modulus yapamwamba ya Young.Chinsinsi cha kuumba kwamphamvu kwambiri ndikuwongolera kutentha kwa nkhungu.Komanso, kulabadira yosalala utsi wa nkhungu patsekeke.Kupanda kutero, pulasitikiyo idzawotchedwa chifukwa cha kutopa kosakwanira komwe kumachitika chifukwa cha jekeseni wothamanga kwambiri.
