Gutera inshinge Ihindagurika rya Plastike isobanutse - PMMA, PC, PET
Ikigereranyo cyo gusoma:Iminota 3, amasegonda 37
Amashanyarazi akoreshwa cyane mu isoko muri iki gihe ni polymethyl methacrylate (bakunze kwita acrylic cyangwa plexiglass, PMMA), polyakarubone (PC), polyethylene terephthalate (PET), nylon ibonerana, AS (acrylic-styrene copolymer), polysulfone (PSF) n'ibindi.Ibintu bitatu bikoreshwa cyane muri plastiki ni PMMA, PC na PET.Bitewe n'imbogamizi z'umwanya, ibikurikira ni ikiganiro kijyanye n'imiterere hamwe no guterwa inshinge za plastiki eshatu.Urashobora kandivugana naba injeniyeri bacuserivisi zitangirwa ubuntu.
1, PMMA
PMMA Ibikoresho bya plastiki
PMMA ifite ubukonje bwinshi kandi ikagenda neza, bityo igomba guterwa mubushyuhe bwo hejuru kandi no kumuvuduko mwinshi, aho ubushyuhe bwo gutera inshinge bugira ingaruka zikomeye kurenza umuvuduko watewe, kandi uko umuvuduko w’inshinge urushaho kuba mwiza. kugabanuka kw'ibicuruzwa.
Ubushyuhe bwo gutera inshinge ni bugari, ubushyuhe bwo gushonga ni 160 ℃, mugihe ubushyuhe bwangirika bugera kuri 270 ℃, bityo igipimo cyo guhindura ubushyuhe bwibintu ni kigari kandi nibikorwa ni byiza.Kubwibyo, kugirango utezimbere amazi, ubushyuhe bwo gutera ni ngombwa.Ingaruka mbi, kuramba, byoroshye gushushanya, byoroshye gucamo ibice nibindi bibazo, bigomba kongerwa mukongera ubushyuhe bwubushyuhe, kunoza inzira ya kondegene, kugirango tuneshe izo nenge.
2, PC
Urupapuro rwa PC
PC ifite ubukonje bwinshi, ubushyuhe bwinshi bwo gushonga, kutagira amazi meza, kubwibyo bigomba kuba inshinge nyinshi (hagati ya 270-320 ℃), ugereranije ugereranije no kugabanya ubushyuhe bwibintu, inzira ntabwo ari nziza nka PMMA, gutunganya biragoye gato kurenza PMMA.igitutu cyo gutera inshinge ziterwa ningaruka zingaruka ni nto, ariko kubera ubukonje, biracyakenewe kuba igitutu kinini cyo gutera inshinge, bihuye kugirango hagamijwe gukumira imihangayiko yimbere iterwa Kugirango wirinde imihangayiko yimbere, igihe cyo gukomeza igitutu gikwiye kuba bigufi bishoboka.
3 PET
PET icupa
PET ikora ubushyuhe buri hejuru, kandi igipimo cyo guhindura ubushyuhe bwibintu ni gito (260-300 ℃), bityo rero umusaruro ntukennye, ariko nyuma yo gushonga, amazi ni meza.Imbaraga za mashini nibikorwa ntabwo biri hejuru nyuma yo guterwa inshinge, kandi bigomba kunozwa binyuze muburyo bwo kurambura no guhindura kugirango tunoze imikorere.
Ubushyuhe bwububiko bugomba kugenzurwa neza kugirango birinde intambara.Ikintu cyingenzi muguhindura, niyo mpamvu ibyifuzo byubushyuhe bwo kwiruka.Ubushyuhe bwububiko bugomba kuba hejuru bitabaye ibyo bizatera ububengerane bwubuso hamwe ningorane zo kumanuka.
Inenge nibisubizo kubice bya plastike bisobanutse
Inenge ni hafi zikurikira:
Ibinyampeke bya feza ukoresheje uburyo bwo kuzuza no guhuza ibintu, guhangayikishwa n'imbere muri anisotropique, icyerekezo gihagaritse cy'imihangayiko, kugirango ibisigarira bitembera ku cyerekezo, hamwe no kutagenda neza kugirango bitange icyerekezo gitandukanye no kuvuka kwa flash filament. , iyo yagutse, irashobora gutuma ibicuruzwa bigaragara.Usibye uburyo bwo gutera inshinge no kubitaho, ibicuruzwa byiza byo kuvura annealing.Kurugero, ibikoresho bya PC birashobora gushyuha kugeza 160 ℃ cyangwa birenga muminota 3-5, hanyuma bigakonja bisanzwe.
Umwuka mwinshibitewe na resin iri mumazi nizindi gaze ntishobora gusohoka, (mugikorwa cya kondegisiyo) cyangwa kubera kuzura bidahagije, hejuru yubuso hamwe no kwihuta cyane hamwe no gukora ibibyimba bya vacuum.
Uburabyo bubikubera ubukana bwububiko, kurundi ruhande byegeranya hakiri kare kuburyo ibisigara bidashobora kwigana imiterere yubuso bwububiko, ibyo byose bituma ubuso bwayo butanga ubusumbane buto, kandi ibicuruzwa bitakaza ububengerane bwabyo.
Shock ripplebivuga ku kuvuka kwinshi kuva ku irembo rigororotse nk'ikigo, impamvu ni uko ubwiza bwashonga ari bunini cyane, ibikoresho by'imbere byegeranye mu mwobo, hanyuma ibikoresho bimeneka kuri ubu buso, hamwe na Ubuso bwo guhungabana.
Igicu cyerabiterwa ahanini numukungugu ugwa mubintu bibisi mukirere cyangwa ibirimo ibikoresho fatizo ni binini cyane kandi biterwa na.
Umwotsi wera n'ibibara byiraburabiterwa ahanini no kubora cyangwa kwangirika kwa barriel kubera ubushyuhe bwaho bwa plastike muri barriel.
Gutera inshinge bikoreshwa cyane mu nganda zinyuranye kandi birashobora kugera ku musaruro utagira ingano, wuzuye mubice mugihe gito.PorLean Tech itanga serivisi zo gutera inshinge ibikoresho byinshi, harimo plastiki na elastomers.Muri makeohereza icyitegererezo cyawehanyuma ubone ibisobanuro byihuse kubuntu hamwe ninama kuri serivisi zijyanye.
