Technology Film: iintlobo, iimpawu, iindawo isicelo

Imbali yale nto yaqala ngokubanzi phakathi kwinkulungwane yokugqibela,. Kuye ezisetyenziselwa ukupakisha impahla yokudla. Le filimu sisiphumo zokuguqulwa ezininzi zobugcisa ubume iikhemikhali kunye nokuveliswa kubuchwepheshe wayilungiselela uluhlu olubanzi iimveliso kunye kwinqanaba eliphezulu ukusetyenziswa.

isakhiwo

Properties ezigcinwe yi-bhanya zeplastiki yobugcisa, nenjongo yayo ixhomekeka ekwakhiweni:

• polyethylene xi ePhakamileyo ezixineneyo ephantsi (LDPE).
• polyethylene elisezantsi uxinzelelo-ukuba isakhiwo ashinyeneyo (iHDPE).
• LDPE yomgama nge sisincoko iguqulwe kancinane.
• Imidlalo ezimbaxa, umzekelo, LDPE kunye iHDPE, ezinepolypropylene.

iimfuno zobugcisa

Le polyethylene ayikho ezingenabungozi, kuba non-yityhefu iqela izinto ezinokutsha ledangatya ka-300 ° C, ezinye iimpawu zixhomekeke ekwakhiweni:

Polyethylene umboniso xi eliphantsi:

• izinto mechanics ixesha elide (0,94 ÷ 0,96 g / cm ^2).
• Esitalini kumaqondo obushushu aphezulu (flow mode kwi 112 C °).
• isakhiwo ezingisayo emafutheni ezityiwayo ne-oyile. Cala ezintweni emuncu kunye obrak.
• Ukungabikho - kwinqanaba eliphezulu permeability, phantse 6 amaxesha liwuphakamele HP film. contact Engasebenziyo kunye hydrocarbon nengathandekiyo - kunye izinto lula oxidizable.
• Film Technology ngokusekelwe iHDPE buyafuneka ukwenzela iimveliso upakisha usisisulu nzala, kwaye iintlobo ezithile iimveliso zokutya.

Le polyethylene ifilimu koxinzelelo oluphezulu:

• It has a ukuxinana 0,91 ÷ 093 g / cm ^2.
• uqine Unengqondo.
• A isantya sokuqukuqela esezantsi ikuvumela ukuba weld amaqhekeza eziphathekayo.
• ukumelana Frost: ukuya ku - 60c °.
• Kumphezulu penti kulula ukuba isicelo.

Linear LDPE: isakhelo nokudalwa bhanya multilayer elula.

uhlobo ngalunye okuthe kwaveliswa kufuneka ihlangabezane neemfuno amaxwebhu zolawulo zikarhulumente:

• Plastic ifilimu zobugcisa - GOST 10354 - 82.
• Polyethylene Nciphisa - GOST 25951 - 83.
• IHDPE GOST 16338 - 85.
• LDPE GOST 16337 - 77.

production

Technical umboniso lukhutshwe iindlela extrusion kwizigaba ezininzi:

• Ukunyibilika kwaye kubethwa nokwakheka semi-ulwelo, imveliso wadluliselwa iintlobo ezahlukeneyo izithiyelo:

1. Khalisa, enika uhlobo bag ukuphakheja. Ngamashishini izixhobo amanzi esatsiba xa kutyhobozela phezulu kwaye yomile phezu lonke ubude, kunye zisancumisa elandelayo igubu kunye jiko ngokupheleleyo-nxeba. inkqubo, evumela ukufumana ngelaphu ku-2400 mm ubude ethatha ixesha elide.
2. Iflethi, ivumela iphepha bhanya ngqo. Emva extrusion, umbandela yomile, wazolula, wabagawula. Le iteknoloji ngokukhawuleza, kodwa sheets polyethylene musa ukudlula 1.5 m.

• Polyethylene oluya ukulungiswa ukuvelisa izinto kunye iimpawu ezinqwenelekayo;

1. Chemical, kongezwe izinto ezithile.
2. Mechanical ngekulula.
3. "Crosslinking" imisebe ion
4. sinjalo emhlabeni. Emva unyango ubushushu, ubume ilaphu uba ukumelana ngakumbi umonakalo.

Technical ifilimu: iimpawu kunye neentlobo kweemveliso ezigqityiweyo

Kuxhomekeka feedstock utshintsho ushishino ungabona polyethylene yobugcisa zilandelayo:

• Svetostabilizirovany: siyakwazi ukumelana eliphezulu imisebe yelanga, lokudla ixhomekeke kwindlela ekwakugquba ngayo ekwenzeni. It has imibala eqaqambileyo: mthubi, luhlaza njalo njalo.
• Finyeza: xa itshiswa litshintsha ubungakanani bayo, obtyagivaya into yomsebenzi ibekwe ngaphakathi. ububanzi web-150 mm ukuya 2500 imikhono mm.

shrinkage:

1. Longitudinal: 40 ukuya 80%.
2. Ezinqamlezayo: 10 ÷ 50%.

• Le akayeki labalandeli: uhlobo olwahlukileyo enamathela kongezwe wezenzi ukuba uguqule iipropati eziphathekayo phantsi iimpawu ezifunekayo.
• Okuye kwabethelelwa: Film Technology kunye umnatha of ezinepolypropylene okanye polyethylene.
• Ngaphaya: izinto umthombo - iHDPE. Esibamba ethylene copolymer film iyiphucule elubala.
• Color: Material - iHDPE, colorants, ekwenzeni.

Polyethylene film Technical: Izicelo

Ukwahluka kweentlobo kuvumela ukusetyenziswa polyethylene phantse kuzo zonke iinkalo zezinto ezenziwa luluntu:

• Construction: kwi ngohlobo izingxobo okanye webs, nezinyuko 60 ÷ 200 microns. Isebenziselwa pallets zokubopha kunye nezinto ikhava kunye nokukhusela iindawo ukungcola.

• kwezolimo:

1. Film Technology sombala omnyama: iintlobo ezahlukeneyo yamaphepha, kuquka elibanzi "phantsi umphunga" amahlumelo (microns babulingana nesandla 60), mulching, ingxinano 10 ÷ 60 microns.
2. Esibamba obala oluphuculweyo; ngokuba zokugcina.

• nokupaka:

1. Shwabanisa film (sleeve ngelaphu) loMthetho eziziiprayimari neziziisekondari, izinto enganeno.
2. Xa uhlobo kweengxowa: inkunkuma ezingxobeni nenkunkuma.

Polyethylene filimu uluhlu enkulu yobuchwephesha, nako ukwanelisa nawuphi na umnqweno lomthengi. Le ethile engundoqo - lithuba eliphezulu yokubola ezo zinto zifundwayo kunye nomgangatho ophantsi processing.
