Na Andy wo mu ruganda rwa Baiyear
Yavuguruwe ku ya 2 Ugushyingo 2022
Hano hari amakuru yamakuru yinganda za Baiyear.Ibikurikira, Baiyear izagabanya uburyo bwo guterwa inshinge mu ngingo nyinshi kugirango tumenye isesengura ryibikoresho fatizo byo guterwa inshinge, kuko hari byinshi birimo.Ibikurikira ningingo ya mbere.
(1).PS (polystirene)
1. Imikorere ya PS:
PS ni polymer amorphous ifite amazi meza no kwinjiza amazi make (munsi ya 00.2%).Nibintu bya pulasitike ibonerana byoroshye gukora no gutunganya.Ibicuruzwa byayo bifite itumanaho ryoroheje rya 88-92%, imbaraga zikomeye zo gusiga no gukomera.Nyamara, ibicuruzwa bya PS biroroshye, bikunda gucika intege imbere, bifite ubushyuhe buke (60-80 ° C), ntabwo ari uburozi, kandi bifite uburemere bwihariye bwa 1.04g \ cm3 (binini cyane kuruta amazi).
Kugabanuka kugabanuka (agaciro muri rusange ni 0.004-0.007in / in), PS iboneye - iri zina ryerekana gusa umucyo wa resin, ntabwo ari kristu.. , ariko irashobora kwangirika na acide ikomeye ya aside irike nka acide sulfurike yibanze, kandi irashobora kubyimba no guhinduka mumashanyarazi amwe n'amwe.)
2. Ibikorwa biranga PS:
Ingingo yo gushonga ya PS ni 166 ° C, ubushyuhe bwo gutunganya ni 185-215 ° C, naho ubushyuhe bwo gushonga ni 180 ~ 280 ° C.Kubikoresho bya flame-retardant, umupaka wo hejuru ni 250 ° C, naho ubushyuhe bwangirika ni 290 ° C, bityo ubushyuhe bwabwo bwo gutunganya ni bugari.
Ubushyuhe bwibumba ni 40 ~ 50 ℃, igitutu cyo gutera inshinge: 200 ~ 600bar, umuvuduko wo gutera inshinge urasabwa gukoresha umuvuduko wihuse, kandi abiruka namarembo bashobora gukoresha ubwoko bwose bwamarembo.Ibikoresho bya PS mubisanzwe ntibikeneye gukama mbere yo kubitunganya keretse bibitswe nabi.Niba gukama bisabwa, ibisabwa byumye ni 80C kumasaha 2 ~ 3.
Bitewe n'ubushyuhe buke bwihariye bwa PS, ibishushanyo bimwe bishobora guhita byegerana kandi bigakomera mugihe bikozwe kugirango bigabanye ubushyuhe.Igipimo cyo gukonjesha kirihuta kuruta ibikoresho bisanzwe, kandi igihe cyo gufungura gishobora kuba kare.Igihe cya plastike nigihe cyo gukonjesha ni kigufi, kandi igihe cyo kuzenguruka kizagabanuka;ububengerane bwibicuruzwa bya PS nibyiza nkuko ubushyuhe bwiyongera.
3.Uburyo busanzwe: ibicuruzwa bipfunyika (kontineri, imipira, amacupa), ibikoresho byubuvuzi bikoreshwa, ibikinisho, ibikombe, ibyuma, ibyuma bifata amajwi, idirishya ryumuyaga nibicuruzwa byinshi - amakarito yamagi.Ibikoresho byo gupakira inyama n’inkoko, ibirango by'amacupa hamwe nibikoresho bya PS byo gutondekanya ifuro, gupakira ibicuruzwa, ibikoresho byo murugo (ibikoresho, ibikoresho, nibindi), amashanyarazi (kontineri ibonerana, diffuzeri yumucyo, firime yerekana, nibindi).
(2).HIPS (polystirene yahinduwe)
1. Imikorere ya HIPS:
HIPS ni ibikoresho byahinduwe na PS.Ifite reberi 5-15% muri molekile.Gukomera kwayo gukubye inshuro enye kurenza iya PS, kandi imbaraga zayo zitera imbere cyane (polystirene ikomeye).Ifite flame retardant grade hamwe na stress yo guhangana.amanota, amanota maremare cyane, amanota menshi yingaruka zingirakamaro, ibirahuri bya fibre byongerewe amanota, hamwe n amanota make asigaye.
Ibindi bintu byingenzi bya HIPS isanzwe: imbaraga zo kugonda 13.8-55.1MPa;imbaraga zingana 13.8-41.4MPa;kurambura kuruhuka 15-75%;ubucucike 1.035-1.04 g / ml;Ibyiza.Ingingo za HIPS zirasobanutse.HIPS ifite amazi make kandi irashobora gutunganywa mbere yo gukama.
2. Ibikorwa biranga HIPS:
Kuberako molekile ya HIPS irimo reberi 5-15%, igira ingaruka kumazi yayo kurwego runaka, igitutu cyo gutera inshinge nubushyuhe bugomba kuba hejuru.Igipimo cyacyo cyo gukonja kiratinda kurenza PS, bityo rero birahagije gufata igitutu, gufata umwanya nigihe cyo gukonja.Inzira yo kubumba izaba ndende gato ugereranije na PS, kandi ubushyuhe bwo gutunganya ni 190-240 ° C.
HIPS isubirana amazi buhoro buhoro, kubwibyo rero ntibisanzwe.Rimwe na rimwe, ubushuhe bwinshi hejuru yibikoresho burashobora kwinjizwa, bikagira ingaruka kumiterere yibicuruzwa byanyuma.Ubushuhe burenze bushobora gukurwaho no kumisha kuri 160 ° F mumasaha 2-3.Hano hari ikibazo cyihariye "cyera cyera" mubice bya HIPS, gishobora kunozwa mukongera ubushyuhe bwimbaraga nimbaraga zifata, kugabanya umuvuduko wo gufata nigihe, nibindi, kandi uburyo bwamazi mubicuruzwa bizagaragara cyane.
4.Ubusanzwe busanzwe bukoreshwa: Ahantu h'ingenzi hasabwa ni ugupakira no kujugunywa, ibikoresho, ibikoresho byo mu rugo, ibikinisho n'ibicuruzwa by'imyidagaduro, n'inganda zubaka.Icyiciro cya Flame retardant (UL V-0 na UL 5-V), polystirene irwanya ingaruka yarakozwe kandi ikoreshwa cyane mumashusho ya TV, imashini zubucuruzi nibicuruzwa byamashanyarazi.
Gukomeza, niba ushaka kumenya byinshi, nyamuneka twandikire.Baiyear ni uruganda runini rugizwe ninganda zikora plastike, gutera inshinge no gutunganya ibyuma.Cyangwa urashobora gukomeza kwitondera ikigo cyamakuru cyurubuga rwacu: www.baidasy.com, tuzakomeza kuvugurura amakuru yubumenyi ajyanye ninganda zitunganya inshinge.
