Mkulu -}}}} Komabe, zochitika zosiyanasiyana zofunsira zimakhala zosiyana pakugwiritsa ntchito pepala la HDPA Nkhaniyi yosanthula mwadongosolo la HDPE
Zoyambira Zoyambira ndi Miyezo Yoyimira Gulu la Zida za HDPPE
HDPA ndi polyethylene ulkethylent unin ndi maunyolo owoneka bwino a molecular ndi kachulukidwe kuyambira 0.941 mpaka 0.965 g / cm³. Kutengera ndi kusiyana njira zopangira, zinthu zofananira za HDPA pamsika zitha kugawidwanso mumitundu yotayidwa. Zakalezo zimapereka ufa wapamwamba kwambiri (kulekerera ± 0.5mm) ndipo ndibwino kuti mupange zida zopepuka. Omaliza imapereka mphamvu kwambiri (yomwe imawoneka bwino kwambiri kuposa 20 kJ / m²) ndipo ndizoyenera kugwiritsa ntchito katundu wamphamvu.
Pankhani ya magwiridwe antchito, okwera -
1. Kukaniza kwa mankhwala:
2. Kupsinjika kwa chilengedwe Kukana Kukaniza: Palibe chopumira mutamizidwa mu njira yotchingira 50 mpaka maola 24.
3. Kutentha kwa kutentha: osachepera 50 mulingo pansi pa katundu 1.8 MPA, kuonetsetsa kukula kosakhazikika.
Kusankhidwa kwa magawo a magwiridwe antchito
(1) Katundu wofanana ndi mfundo yofananira
Zofunsira zokambirana ndi katundu wolemera kapena kukangana pafupipafupi (monga zida zamigodi), zakuthupi zimasokoneza ndizofunikira kwambiri. Powonjezera 2% {3} 5% ya Ultra {{8} Pa ntchito zamagetsi (monga ma antchito osabereka), othamanga kwambiri okhala ndi mphamvu yayikulu kuposa kapena yofanana ndi 2500 modulus wamkulu kuposa kapena wofanana ndi 800 MPA yoyenera kuyenera kusankhidwa.
(2) Kusintha kwa chilengedwe
Munthawi yayitali {- gwiritsani ntchito, UV uve ndi njira yolerera. Ma sheet a HDPA adasinthidwa ndi 2% -3% ya carborm yomwe ingakuletse pokana nyengo ndi 3-5<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) Kugwirizana
Mukamajowina ma sheet omwe amawotcha mafuta, tikulimbikitsidwa kusankha sing'anga - kwa osungunuka (MFR) ya 0,1 {7 { Izi zimapangitsa kuti mupeze mphamvu yolumikizira (kumeta ubweya wokulirapo kuposa kapena wofanana ndi 85% yazomwe zimapangitsa kuti kusokonezedwa ndi madzi ambiri. Kwa CNC Kudula kwa CNC, kalasi yodulira kwaulere ndi MFR> 0,5 g / 10 min tikulimbikitsidwa kuti muchepetse kwambiri chida.
Njira zakuthupi zothetsera zochitika wamba
(1) Chitetezo cha Milsion
Kwa mapulogalamu a Tanking a Tank omwe amapezeka ndi zowononga monga hydrochloric acid ndi sodium hydroxide, 15% ya mitsuko yolimbikitsidwa. Modulus wake wa mulungu wake ukhoza kufikira 1200 MPA ROPPARD EXEMICE BAMO (POPANDA KUSINTHA KWAMBIRI KWAMBIRI MU CHITSANZO CHA 50% kwa chaka chimodzi).
(2) Makina oteteza makina
Kwa makina oyendetsa sitima yapamsewu, olondola - Izi zimalepheretsa kwambiri zachitsulo ndikulepheretsa kuvala njanji yotsogolera.
(3) Malo oteteza zachilengedwe
Kwa matenda a chimbudzi chophimba, pepala lopepuka la HDPA lokhala ndi chindapusa cha 0,7 g / masentimita Kumachepetsa mphamvu {}}}
Kusankha kwazinthu zakuthupi kwa HDPE ndikofunikira kufanana ndi magawo a zinthu zogwirira ntchito ndi zofunikira kugwiritsa ntchito. Pazochita zaukadaulo, zinthu zingapo, monga mphamvu zolimbitsa thupi, kukana chilengedwe, ndi kukonza zachuma, ziyenera kuganiziridwa mokwanira, komanso kudalirika kwa njira yoyeserera iyenera kutsimikiziridwa. Kupita patsogolo kwa matekinoloje ndi kusintha, kusintha kwa mapepala a HDPPE. Izi zimafuna mapangidwe apamwamba kuti apitirize kumvetsetsa kwawo njira zomwe zimagwirizanitsa microstructuctuctucation yam'madzi ndi macascopic.
