Film Technology: hoailona ia mea, ano, noi mau

I ka moolelo o keia mea, hoomaka ae la ka lono a hiki i ka waena o ka hope ke kenekulia,. Ua Ua hoʻohana 'ia no ka hāʻawe o ka waiwai o ka meaʻai oihana puolo. Ka ho film ia hoʻi i ka hopena o ka lau oaoieei-ka hoʻololi 'ana o ka haku mele' ana a me ka Nine Inch? Iecaianoaaiiuo o ka 'ike loea hou ana, ua wae iho la ia ia me ka laulā huahelu o nā huahana a me ke kiʻekiʻe nui o ka pono.

'ole

Ka waiwai paa ma ka oaoieei-ea ho film, a me kona manao hilinai ma o ka haku mele:

• High puʻe polyethylene me ka haʻahaʻa nuʻa (LDPE).
• Low-puʻe polyethylene me ke anuanu 'ole (HDPE).
• Laina LDPE me ka Hoʻololi 'haku mele' ana.
• Likeʻole o ka hui: no ka laʻana, LDPE a me ka HDPE, polypropylene.

oaoieei-koi

Ke polyethylene mea oleʻawahia, mea ole-ʻawahia pūʻulu flammable mea me ka waihonaʻike wahi o ka 300 ° C, i nāʻano hilinaʻi ma o ka haku mele:

Polyethylene ho film o haʻahaʻa puʻe:

• Mechanically mau nō mea (0,94 ÷ 0,96 g. / Knm ^2).
• Ka pilina paʻa ke kiʻekiʻe Mahana O Ke Kai (pele 'ano ma ka 112 C °).
• Paakiki 'ole i ka edible i ka momona, a me nā mea kāhinu,. 'ākilikai iʻakika a me kona'ākilikai waiwai.
• Hoi i emi kana - kiʻekiʻe permeability pae, kokoke 6 manawa ma luna ma mua o ka HP ho film. Helu kuhi hui 'ana me hydrocarbons a undesirable - me hoopuni oxidizable waiwai.
• Film Technology ka nānā 'ana ma luna o HDPE mea paʻa mau no ka'ōpala me nā huahana undergoing sterilization, a me ka hanaʻano o kaʻai me nā huahana.

Ke polyethylene ho film o kiʻekiʻe puʻe:

• Ua loaʻa i ka pa apŘ o 0,91 ÷ 093 g. / Knm ^2.
• Kupono tensile ikaika.
• A haʻahaʻa pele ana e leie aku i ka weld mea liilii.
• Hau paa ia'ku: mai i - 60C °.
• Ma ka ili o ka HW mea maʻalahi e pili.

Laina LDPE: i? Aieao no ka mea i hanaia kīkoʻo multilayer Film o.

Kēlā me kēiaʻano o ka mea he pono i kō nā koi o ka moku'āina hoʻokonukonu palapala:

• Lula ea Auana iiaie oaoieei - GOST 10354 - 82.
• Polyethylene menemene - GOST 25951 - 83.
• HDPE GOST 16338 - 85.
• LDPE GOST 16337 - 77.

Kōmike Auana ua hua mai ma ka extrusion i kūpono i loko o kekahi mau kahua o ka hoʻonaʻauao.

• Ke Kēhaupaʻa a me ke puhi ana i kalaka nui-wai haku mele 'ana, ka mea i hiki ia auoiaea ma nāʻano o nā mau maunu.

1. Ke komo lima, e haawi ana i ke ano o ka eke'ōpala. Ma ka mākeke o ka kīʻamo mea e pehu ae mai, a ua maloo ma ka lōʻihi holoʻokoʻa, a me ka mea hope puakai o ka pahu, a me ka piha-ʻeha coils. Manawa-e hoopau ana kaʻina, e leie aku e kiʻi i ka canvas i ka 2400 mm o ka lōʻihi.
2. I lalo, e leie pololei Auana kuina. Ma hope o extrusion, me ka lako e ua maloo,'ō a oki. Kēia wikiwiki enehana, akā, i ka polyethylene a lahilahi mai i oi aku mamua o 1.5 m.

• Polyethylene kŰlń ao nā loli i ka paka i kekahi mea me ka makemake ka waiwai:

1. Nine, a me ka hou ana o ka mea i ho'ākāka 'hehee wale.
2. Mechanical ma ka hohola ana.
3. "Crosslinking" ma ion pāhawewe
4. Thermal noaaeeecaoee. Ma hope o ka wela lapaʻau, ka lole 'ole i oi hoʻopale i me mechanical poino.

Kōmike Auana: 'ano a me ke ano o ka hoʻopau' ana i huahana

Ke kaumaha ma muli o ka feedstock nā pāʻoihana hoʻololi 'ia ke ike i ka hahai oaoieei-polyethylene:

• Svetostabilizirovany: i ke kiʻekiʻe ia'ku i ka pāhawewe lā, i ka wa e ola ana hilinaʻi nui ma ka lehulehu o nā stabilizers. Ua he ao alohilohi i'ōniʻoniʻo: melemele, omaomao, a no laila, ma luna o.
• Emi aku ana lakou: i ka wa wela hoʻololi kona nui, obtyagivaya e hoopii mai ai ke aupuni 'maloko. pūnaewele puni honua akea o ka 150 mm o ka 2500 mm o lole a.

shrinkage:

1. Lonikū: 40 i ka 80%.
2. Transverse: 10 ÷ 50%.

• Ke ahupapa menemene: kekahi ano o ka penaʻana me ka hou ana o reagents e hoʻololi i ka mea waiwai ma lalo o ka koi 'ia' ano.
• Ka ikaika: Film Technology me ka hei o ka polypropylene a polyethylene.
• Ka aniani moakaka: ke kumu - HDPE. 'etolina copolymer hydrophilic Auana mea kiʻekiʻe mäliko.
• Waihoʻoluʻu: Material - HDPE, colorants, stabilizers.

Polyethylene ho film Kōmike: noi

Ke 'ano o ka laha' e leie aku ka hana o ka polyethylene i aneane pau spheres o kanaka aayoaeuiinoe:

• ? Ieoaeunoai: ma ke ano o ka lole a me ka Pūnaewele Puni Honua, mānoanoa 60 ÷ 200 microns. Hoʻohana 'ia no ka'ōpala pallets a me ka uhi mea, a hoʻopale ai surfaces mai ka mea hoʻohaumia.

• ka Mahiai:

1. Film Technologyʻeleʻele pigment: nāʻano likeʻole o ka pepa, a me ka uhi ana "ma lalo o mahu" hoi e pana aku (mānoanoa 60 microns), mulching, nuʻa 10 ÷ 60 microns.
2. Hydrophilic me ka hoʻokāʻoi 'mäliko: no ka hoʻoulu mea kanu.

• hāʻawe:

1. Emi ho film (lole canvas) o ka iniiaiie, a kiʻekiʻe, ho'ēmi maka mea.
2. Ma ka palapala a mau eke: no ka'ōpala neoneo a me ka neoneo.

Polyethylene ho film mea he nui huahelu o oaoieei-, ke panai ai i kekahi makemake o ka mea kūʻai mai. Na ka papa kuhikuhiE drawback - ia mea he kiʻekiʻe wā o ka decomposition o ka mea, a me ka haahaa nui o ka aaioee.
