Icyitonderwa: Ibisobanuro birashobora guhinduka nta nteguza.
Ibisobanuro ku bicuruzwa
Ibyiza bya firime izuba (EVA) byavuzwe muri make kuburyo bukurikira:
1. Gukorera mu mucyo no gufatira hejuru birashobora gukoreshwa muburyo butandukanye, harimo ibirahuri, ibyuma na plastiki nka PET.
2. Kuramba neza birashobora kurwanya ubushyuhe bwinshi, ubushuhe, imirasire ya ultraviolet nibindi.
3. Kubika byoroshye. Ubitswe mubushyuhe bwicyumba, gufatira kwa EVA ntabwo bigira ingaruka kubushuhe hamwe na firime zinjira.
4. Ugereranije na PVB, ifite imbaraga zikomeye zo gukumira amajwi, cyane cyane kumajwi yumurongo mwinshi.
5. Ahantu ho gushonga, byoroshye gutemba, bikwiranye nuburyo bwo kumurika ibirahuri bitandukanye, nkikirahure cyashushanyije, ikirahure gikonje, ikirahure kigoramye, nibindi.
Filime ya EVA ikoreshwa nk'ikirahure cyometseho, cyujuje byimazeyo ubuziranenge bwigihugu "GB9962-99" kubirahuri byanduye. Ibikurikira nurugero rwa 0.38mm yuburebure bwa firime ibonerana.
Ibipimo ngenderwaho ni ibi bikurikira:
| Icyerekana Umushinga | |
| Imbaraga zingana (MPa) | ≥17 |
| Itumanaho rigaragara (%) | ≥87 |
| Kurambura kuruhuka (%) | 50650 |
| Igipimo cy'ibicu (%) | 0.6 |
| Imbaraga zo guhuza (kg / cm) | ≥2 |
| Kurwanya imirasire byujuje ibisabwa | |
| Kwinjiza amazi (%) | ≤0.15 |
| Ubushyuhe bwo guhangana | |
| Kurwanya ubushuhe bujuje ibisabwa | |
| Ingaruka zo guhangana nazo zujuje ibisabwa | |
| Kurasa imifuka ingaruka zujuje ibyangombwa | |
| Igipimo cya UV | 98,50% |
Ni izihe nyungu n'ibibi bya firime ya EVA ipakira?
Ikintu nyamukuru kigizwe na firime ya EVA ni EVA, hiyongereyeho inyongeramusaruro zitandukanye, nka agent ihuza, umubyimba, antioxydeant, stabilisateur yumucyo, nibindi. kurwanya no kugiciro gito. Ariko inenge ya PID nayo iragaragara.
Kugaragara kwa moderi ebyiri-ibirahuri bisa nkaho biha EVA amahirwe yo gutsinda inenge. Kubera ko umuvuduko wamazi wikirahure cyikirahuri hafi ya zeru, amazi make cyangwa amazi ya zeru ya moderi yikirahure kabiri bituma irwanya hydrolysis ya EVA itakiri ikibazo.
Amahirwe nibibazo bya POE ipakira
Yatejwe imbere na catalizike ya metallocene, POE nubwoko bushya bwa polyolefin thermoplastique ya elastomer hamwe na misile igereranije ikwirakwizwa ryinshi, ikwirakwizwa rya comonomer hamwe nuburyo bugenzurwa. POE ifite ubushobozi bwo guhagarika amazi yumuyaga nubushobozi bwa ion barrière. Igipimo cyo kwanduza amazi ni hafi 1/8 cya EVA, kandi gusaza ntabwo bitanga ibintu bya aside. Ifite imikorere myiza yo kurwanya gusaza kandi ni fotokoltaque ikora neza kandi yizewe cyane. Ibikoresho byo guhitamo ibice bigize firime.
Sisitemu yo kugaburira ya gravimetricike ituma ibintu bitandukanye byongeweho, byongeweho amazi nibikoresho fatizo bigaburirwa neza. Sisitemu yo gukuramo ubushyuhe buke kugirango yizere kuvanga bihagije mbere yo guhindagurika kugirango hirindwe inyongeramusaruro. Igishushanyo cyihariye cya Casting igice gitanga igisubizo cyiza kubuzuza roller no gutemba kwamazi. Igikoresho kidasanzwe cyo kumurongo kugirango ukureho imihangayiko y'imbere. Sisitemu yo kugenzura impagarara zemeza neza ko impapuro zoroshye zitangwa neza mugihe cyo gukonjesha, gukurura no guhinduranya.Uburyo bwo gupima uburebure bwumurongo no gupima inenge burashobora gutanga ibitekerezo-nyabyo byerekana ubwiza bwibikorwa bya firime yizuba ya EVA / POE.
Filime ya EVA / POE ifotora ikoreshwa cyane cyane mugushyiramo modul ya fotovoltaque kandi nibikoresho byingenzi byamafoto yerekana amashanyarazi; Irashobora kandi gukoreshwa mubikorwa bitandukanye nkurukuta rwububiko bwikirahure, ikirahure cyimodoka, ibishishwa bishushe, nibindi.
