Izina ryimiti ya acrylic ni polymethylmethacrylate (PMMA mucyongereza).Bitewe nubusembwa bwa PMMA nkuburemere buke bwo hejuru, guswera byoroshye, kurwanya ingaruka nke, hamwe no gukora nabi gutembera neza, guhindura PMMA byagaragaye kimwekindi.Nka copolymerisation ya methyl methacrylate hamwe na styrene na butadiene, kuvanga PMMA na PC, nibindi.
Imyitwarire yimyitwarire yaPMMAni bibi kurenza ibya PS na ABS, kandi ibishishwa bya elegitoronike byumva neza ihinduka ryubushyuhe.Mugihe cyo kubumba, ibishishwa bya elegitoronike bihinduka cyane cyane bitewe nubushyuhe bwo gutera.PMMA ni polymer amorphous ifite ubushyuhe burenze 160°C n'ubushyuhe bwo kubora bwa 270°C.
1. Kujugunya plastiki
PMMA ifite urugero runaka rwo kwinjiza amazi, hamwe n’igipimo cy’amazi kingana na 0.3-0.4%.Gutera inshinge bisaba ubuhehere buri munsi ya 0.1%, mubisanzwe 0.04%.Kuba hari ubushuhe butera ibibyimba, imirongo yumuyaga, no kugabanya gukorera mu mucyo.Igomba rero gukama.Ubushyuhe bwo gukama ni 80-90℃kandi igihe cyo kumisha kirenze amasaha 3.Ibikoresho bisubirwamo birashobora gukoreshwa 100% mubihe bimwe.Umubare nyawo uterwa nibisabwa ubuziranenge, mubisanzwe birenga 30%.Ibikoresho bisubirwamo bigomba kwirindwa kwanduzwa, bitabaye ibyo bizagira ingaruka kumucyo numutungo wibicuruzwa byarangiye.
2. Guhitamo imashini ibumba inshinge
PMMA ntabwo isabwa bidasanzwe kumashini ibumba inshinge.Kubera ubwinshi bwayo bushonga, bisaba umwobo wimbitse nu mwobo munini wa diameter nozzle.Niba imbaraga zisabwa mubicuruzwa ziri hejuru, umugozi ufite igipimo kinini kigomba gukoreshwa muburyo bwa plastike yubushyuhe buke.Byongeye, PMMA igomba kubikwa muri hopper yumye.
3. Igishushanyo mbonera
Ubushuhe burashobora kuba 60℃-80℃.Diameter yumuyoboro nyamukuru igomba guhuza icyuma cyimbere.Inguni nziza ni 5° kugeza 7°.Niba ushaka gutera inshinge 4mm cyangwa hejuru yibicuruzwa, inguni igomba kuba 7° na diameter yumuyoboro munini ugomba kuba 8 kugeza 8°.10mm, uburebure rusange bwirembo ntibugomba kurenga 50mm.Kubicuruzwa bifite uburebure bwurukuta ruri munsi ya 4mm, umuyoboro wumuyoboro wa diameter ugomba kuba 6-8mm
Kubicuruzwa bifite uburebure bwurukuta rurenze 4mm, diameter yumwiruka igomba kuba 8-12mm.Ubujyakuzimu bw'irembo rya diagonal, rimeze nk'abafana kandi rihagaritse ibice bigomba kuba 0.7 kugeza 0.9t (t ni uburebure bw'urukuta rw'ibicuruzwa).Diameter y irembo ryinshinge igomba kuba 0.8 kugeza 2mm;ingano ntoya igomba guhitamo kubwiza buke.
Imyobo isanzwe iri muri 0,05 yimbitse, ubugari bwa mm 6, naho inguni iri hagati ya 30′-1° naho igice cyaka kiri hagati ya 35′-1°30°.
4. Gushonga ubushyuhe
Irashobora gupimwa nuburyo bwo gutera mu kirere: kuva kuri 210℃kugeza 270℃, ukurikije amakuru yatanzwe nuwabitanze.
Sohoka ku ntebe yinyuma, kora imashini itera inshinge nozzle usige umuyoboro munini ushing, hanyuma ukore intoki ukore inshinge za pulasitike, aribwo buryo bwo gutera umwuka.
5. Ubushyuhe bwo gutera
Gutera inshinge byihuse birashobora gukoreshwa, ariko kugirango wirinde guhangayika cyane imbere, nibyiza gukoresha inshinge nyinshi, nka buhoro-buhoro-buhoro, nibindi. Iyo utera ibice byimbitse, koresha umuvuduko mwinshi.
6. Igihe cyo gutura
Niba ubushyuhe ari 260°C, igihe cyo gutura ntigishobora kurenza iminota 10.Niba ubushyuhe ari 270°C, igihe cyo gutura ntigishobora kurenza iminota 8.
ZAOGE Film Crusherikwiranye no kumenagura ibikoresho bitandukanye byoroshye kandi bikomeye byo gusakara hamwe nubunini bwa 0.02 ~ 5MM, nka PP / PE / PVC / PS / GPPS / PMMA firime, impapuro, namasahani akoreshwa mububiko, gupakira, nizindi nganda.
Irashobora gukoreshwa mugukusanya, kumenagura no gutanga ibikoresho byo kumpera byakozwe na extruders, laminator, imashini zipapuro, hamwe nimashini zisahani.Kurugero, ibikoresho byajanjaguwe bitwarwa numufana utanga umuyoboro unyuze kumuyoboro ugana icyuma gitandukanya inkubi y'umuyaga, hanyuma ugasunikwa mu cyambu cya extruder screw ibiryo ukoresheje ibiryo bigaburira kuvanga byikora hamwe nibikoresho bishya, bityo bikageraho bigahita birengera ibidukikije no kubikoresha.
