Ni irihe tandukaniro riri hagati ya EVA, EPE nibikoresho bya sponge?

EVAikozwe muri copolymerisation ya Ethylene (E) na vinyl acetate (VA), yitwa EVA, kandi ni ibintu bisanzwe bisanzwe. EVA ni ubwoko bushya bwibikoresho byangiza ibidukikije. Ikozwe muri EVA ifuro, inesha inenge ya reberi isanzwe ifata nka brittleness, deformation, hamwe no gukira nabi. Ifite ibyiza byinshi nkamazi nubushuhe, kutagira inkuba, kubika amajwi, kubungabunga ubushyuhe, plastike nziza, gukomera gukomeye, gutunganya ibicuruzwa, kurengera ibidukikije, kurwanya ingaruka, kurwanya kunyerera no kurwanya ihungabana, nibindi. Ifite kandi imiti irwanya imiti kandi ni ibikoresho byiza byo gupakira. ubundi buryo. EVA ifite plastike ikomeye cyane. Irashobora gupfa-muburyo ubwo aribwo bwose, kandi irashobora guhindurwa ukurikije ibishushanyo byabakiriya. Isakoshi yo kubika ya EVA irashobora guhindurwa hamwe nibara, imyenda hamwe numurongo bisabwa nabakiriya. EVA ikoreshwa cyane mugukanguka, kurwanya kunyerera, gufunga no kubika ubushyuhe bwibikoresho bya elegitoronike, gutondekanya udusanduku dutandukanye twapakira, amabati hamwe n’inganda. Imikorere nko gukingira, kurwanya-static, kutirinda umuriro, guhungabana, kubika ubushyuhe, kurwanya kunyerera, no gukosorwa. Kwambara kandi birwanya ubushyuhe. Gukingira hamwe nindi mirimo.

Izina ry'ubumenyi rya EPE ryagurwa polyethylene, izwi kandi nka puwaro. Nubwoko bushya bwibikoresho byo gupakira bishobora kugabanya no gukuramo ibinyeganyega. Nibicuruzwa byinshi byitwa polyethylene biva muri polyethylene nkeya (LDPE) nkibikoresho nyamukuru. EPE iparo ya puwaro ifuro muburyo budasanzwe ukoresheje butane, ituma EPE yoroshye cyane, ikomeye ariko idacitse, hamwe nubuso bworoshye. Irashobora gukumira neza ibyangiritse biterwa no guterana mugihe cyo gupakira ibicuruzwa kandi bifite uburyo bwiza bwo kwinjiza no kurwanya ibintu. . Ubu irakoreshwa cyane mugupakira ibikoresho byamashanyarazi, ibikoresho, ibikoresho bya elegitoroniki neza nibindi bicuruzwa. Ipamba ya EPE isaro irashobora kwihanganira amavuta yubukanishi, amavuta, nibindi. Kuberako ari umubiri wuzuye, ntushobora kwinjiza amazi. Irashobora kuba idafite amavuta, irinda ubushuhe, irinda ihungabana, irinda amajwi hamwe n’ubushyuhe, kandi irashobora kandi kurwanya isuri y’ibintu byinshi. EPE isaro ya puwaro irashobora kuba yujuje ibyangombwa bitandukanye byo gupakira, antistatike, flame retardant, nibindi ukurikije ibicuruzwa bitandukanye. Ifite kandi amabara meza kandi byoroshye kuyatunganya.
Izina ry'ubumenyi rya sponge ni polyurethane yoroshye ya rubber, ifite imikoreshereze igaragara mu kwinjiza ibintu, kurwanya ubukana, no gukora isuku. Ubwoko bugabanijwemo polyester sponge na polyether sponge, bigabanijemo ubwoko butatu: gusubira hejuru, kugaruka hagati no gutinda buhoro. Sponge yoroshye muburyo bwimiterere, irwanya ubushyuhe (irashobora kwihanganira ubushyuhe bwa dogere 200), kandi byoroshye gutwika (flame retardants irashobora kongerwamo). Ukurikije ubunini bwimbere bwimbere, burashobora kwerekana ubucucike butandukanye kandi burashobora kubumbabumbwa muburyo butandukanye nkuko bikenewe. Ifite uburyo butandukanye bwo gukoresha kandi ikoreshwa cyane cyane mukutagira amashanyarazi, kubika ubushyuhe, kuzuza ibikoresho, ibikinisho byabana, nibindi.

Itandukaniro nyamukuru hagati yibi bitatu ni ibi bikurikira:
1. Turashobora kubona itandukaniro riri hagati yabo n'amaso yacu yambaye ubusa. Sponge niyoroheje muri bitatu. Ni umuhondo muto kandi byoroshye. EVA nimwe iremereye muri bitatu. Ni umukara kandi biragoye. EPE isaro ipamba igaragara yera, byoroshye gutandukanya sponge. Sponge izahita isubira mumiterere yumwimerere niyo waba uyikanda ute, ariko ipamba ya EPE isaro izahita yunvikana kandi yumvikane neza iyo uyikanze.
