Urupapuro rwo hejuru - intege nke za polyethylene (hdpe) zikoreshwa cyane mu nganda za mitique, ubwubatsi, hamwe n'inganda zifata imashini bitewe n'umutekano mwiza wa chimique, wambare imitungo yoroheje. Nyamara, ibintu bitandukanye bya porogaramu byerekana itandukaniro ryibintu bifatika kubisabwa byimikorere ya HDP, bigahitamo guhitamo ibintu bifatika kugirango ireme ireme kandi ryo kuramba. Iyi ngingo isesengura gahunda ya HDPE Urupapuro rwo gutoranya ibikoresho kuva muburyo butatu: Ibipimo byibanze, ibipimo byingenzi byimikorere, hamwe nibisanzwe.
Imitungo yibanze hamwe nuburyo bwo gutondekanya ibikoresho bya HDPE
HDPE ni kristu cyane ya polyethylene resin yuzuye iminyururu yangiritse cyane hamwe nubucucike butandukanye kuva 0.941 kugeza 0.965 G / CM³. Ukurikije itandukaniro muri gahunda yumusaruro, ibicuruzwa bisanzwe byimpapuro za HDPA ku isoko birashobora gushyirwa mu byiciro byinshi kandi byoroshye - ubwoko. Ibyambere bitanga uburinganire bwihariye (kwihanganira ± 0.5mm) kandi bikwiranye no kubamo ibikoresho byemewe. Iheruka itanga imbaraga zidafite imbaraga (Ingaruka nziza Imbaraga Zisumba cyangwa zingana na 20 KJ / M²) kandi zikwiriye gusaba hashingiwe ku mitwaro ifite imbaraga.
Kubijyanye n'imikorere yibanze, hejuru -} Urupapuro rwa HDPE rugomba kubahiriza ibipimo bikurikira:
1. Kurwanya imiti: inert to acide ikomeye nka aside sulfuric na aside ya nitric mu gihe cya 80%, ndetse nibiti bisanzwe.
2. Guhangayikishwa n'ibidukikije Kurwanya: Nta muco wometse nyuma yo kwibiza mu gisubizo cyo gukumira ku rwego rw'ibipimo 50 mu masaha 24.
3. Ubushyuhe bwo guhindura ubushyuhe: Ntabwo ari munsi ya 50 munsi yumutwaro wa 1.8 MPA, guharanira umutekano hagati mubihe bisanzwe.
Guhitamo Ibipimo byingenzi byingenzi
(1) umutungo wa mashini uhuza ihame
Kubisabwa ukurikije imitwaro iremereye cyangwa guterana amagambo kenshi (nkibikoresho byo gucukura amabuye y'agaciro), ibikoresho byambariye ibikoresho nibyingenzi. By adding 2%-5% ultra-high molecular weight polyethylene (UHMWPE) to the blend, sheet wear can be reduced to 0.08-0.12 cm³/1.61 km (ASTM D1044 test standard). Kubisabwa mu nyubako (nkabarera by'agateganyo), amanota akomeye-akomeye hamwe n'imbaraga za tensile irenze cyangwa ingana na 2500 MPA irenze 800 MPA igomba gutorwa.
(2) Ibikorwa byo kuzamura ibidukikije
Kera -}} isohoka hanze, uv ass nubusa bwibanze. Amabati ya hdpe yahinduwe na 2% -3% Black Black arashobora kunoza ibihe byikirere (Quv Ibizamini byo gusaza byerekana itandukaniro rya Δe<3 after 500 hours). For applications involving contact with food or pharmaceutical media, sanitary-grade resins that comply with FDA 21 CFR 177.1520 must be selected to ensure heavy metal migration is less than 0.1 ppm.
(3) gutunganya
Iyo uhuza impapuro ukoresheje ubushyuhe, birasabwa guhitamo hagati - kuri hasi {{1 {7- 0.3 GRE / 10 min. Ibi byemeza imbaraga zisukuye (imbaraga zo guswera zirenze cyangwa zingana na 85% yibikoresho byababyeyi) mugihe wirinze guhindura Weld deformation biterwa n'amazi menshi. Kuri CNC Gukata, amanota yo gutema ubuntu hamwe na MFR> 0.5 G / 10 min irasabwa kugabanya cyane cyane kwambara.
Ibisubizo by'ibintu kubisanzwe bya Porogaramu
(1) Kurinda imiti
Kuri tank loank ikoreshwa ryerekanwe nibitangazamakuru byangiza nka aside hydrochloric na sodium hydroxide, fibre ya 15% yikirahure ishimangirwa na HDPA. Modulus yo muriyo irashobora kugera kuri 1200 MPA mugihe ikomeza kurwanya imiti myiza ya chemique (nta gutesha agaciro nyuma yo kwibizwa muri 50% igisubizo cyumwaka umwe).
(2) Sisitemu yo Kurinda imashini
Kubikoresho bya Machine biyobora abashinzwe umutekano, precision - page ifunzwe hamwe nubuso bwa rare ya ra munsi cyangwa ingana na 0.8 μ Ibi bigabanya neza icyuma cyangiza kandi birinda kwambara gukabije hejuru ya gari ya moshi.
(3) Ibigo birinda ibidukikije
Kuburyo bwo kuvura imyanda, urupapuro rworoshye rwa HDPE rufite ubucucike bwa 0.7 G / CM³ rushobora kugabanya ibiro bihagije kuri 40% mugihe ufashe umutwaro uhagije {mugihe gikwirakwije umutwaro uhagije -.
Guhitamo ibikoresho bya HDPE urupapuro ni muburyo bwo guhuza ibikorwa byukuri bihuye nibisabwa nibisabwa. Mumyitozo yubwubatsi, ibintu byinshi, nkimbaraga za mashini, kurwanya ibidukikije, no gutunganya ubukungu, bigomba kumvikana, kandi kwizerwa kubisubizo byatoranijwe bigomba kugenzurwa binyuze mumashanyarazi. Hamwe niterambere muguhuza no guhindura ikoranabuhanga, ibisubizo byihariye bya HDPA bitwara ibyifuzo byayo muburyo busaba porogaramu. Ibi bisaba ibikoresho bya injeniyeri kugirango bishoboke gusobanukirwa uburyo bwo guhuza ibikorwa nibikoresho byakazi na macroscopique.
