Film Technology: mitundu, maonekedwe, malo ntchito

Mbiri ya nkhaniyi anayamba kunja ngakhale mu zaka za m'ma otsiriza,. Iwo ankagwiritsa ntchito pa kulongedza katundu katundu chakudya makampani. The filimu chifukwa cha zosintha angapo luso mipweya ndi kupanga njira zamakono zimene anam'patsa ndi osiyanasiyana mankhwala ndi mkulu mlingo wa ntchito.

kapangidwe

Katundu unachitikira ndi luso pulasitiki filimu, ndi cholinga chake zimadalira zikuchokera:

• Kuthamanga polyethylene kukhala otsika kachulukidwe (LDPE).
• Low-kuthamanga polyethylene ndi dongosolo wandiweyani (HDPE).
• Liniya LDPE ndi zikuchokera kusinthidwa.
• Kusiyana kwa pawiri: mwachitsanzo, LDPE ndi HDPE, polypropylene.

amafuna luso

The polyethylene si poizoni, ndi sanali poizoni gulu flammable zakuthupi ndi mfundo kung'anima 300 ° C, makhalidwe ena zimadalira zikuchokera:

Polyethylene filimu ya mochedwerako:

• Umakaniko cholimba chuma (0,94 ÷ 0,96 g / masentimita ^2).
• Khola ndi kutentha (otaya mode pa 112 C °).
• Kapangidwe mwakhama kuti mafuta edible ndi mafuta. Ndale ndi zinthu acidic ndi zamchere.
• Kupanda - mkulu permeability msinkhu, pafupifupi 6 zina kuposa filimu HP. kukhudzana yolakwika ndi chimasanduka ndi osafunika - ndi zinthu mosavuta oxidizable.
• Film Technology zochokera HDPE ndi yofunika kwambiri kwa mankhwala ma CD likufa yolera yotseketsa, ndi mderalo katundu chakudya.

The polyethylene filimu ya kuthamanga:

• Iwo ali osalimba a 0,91 ÷ 093 g / masentimita ^2.
• Oganiza kwamakokedwe mphamvu.
• A otsika otaya mlingo amalola china chotulutsa zinthu zidutswa.
• Frost kukana: mpaka - 60C °.
• Padziko utoto ndi zovuta kutsatira.

Liniya LDPE: dongosolo kwa chilengedwe cha mafilimu Tambasula multilayer.

Mtundu uliwonse wa zinthu opangidwa ayenera kukwaniritsa ziyeneretso zolembedwa boma zolimbana:

• Pulasitiki filimu luso - GOST 10354 - 82.
• Polyethylene kuotcha - GOST 25951 - 83.
• HDPE GOST 16338 - 85.
• LDPE GOST 16337 - 77.

kupanga

Luso filimu amapangidwa ndi njira extrusion mu magawo angapo:

• Kusungunuka ndi kuwomba kwa theka-madzi zikuchokera, linanena bungwe kudzera osiyanasiyana nyambo:

1. Mphete, kupereka mtundu wa thumba ma CD. Pa kubwereketsa nkhani nozzle amawonjezereka ndi nafota pa kutalika lonse, ndi kumangika wotsatira wa ng'oma ndi coils zonse bala. Nthawi yambiri ndondomeko, amene amalola kuti chinsalu mpaka 2400 mm m'litali.
2. Mosabisa, amalola filimu pepala mwachindunji. Pambuyo extrusion, chuma zouma, anatambasula ndi kudula. Izi luso mofulumira, koma mapepala polyethylene musalumphe 1.5 m.

• Polyethylene chimafikira kusinthidwa kubala chuma ndi katundu adakhumba:

1. Mankhwala, ndi Kuwonjezera wa zinthu zenizeni.
2. Mawotchi ndi kutambasula.
3. "Crosslinking" ndi cheza ion
4. Matenthedwe olimba. Pambuyo mankhwala kutentha, kapangidwe nsalu umakhala kugonjetsedwa ndi kuwononga makina.

Luso filimu: makhalidwe ndi mitundu ya mankhwala yomalizidwa

Malinga feedstock zosintha malonda kuwona izi polyethylene luso:

• Svetostabilizirovany: ali zonyamula dzuwa cheza, ndi moyo zimadalira ambiri stabilizers. Iwo ali kuwala mitundu: achikasu, wobiriwira ndi zina zotero.
• Kuotcha: pamene mkangano amasintha kukula kwake, obtyagivaya chinthu ili mkati. ukonde m'lifupi 150 mamilimita kwa 2500 mamilimita manja.

shrinkage:

1. Kotenga: 40 mpaka 80%.
2. Yopingasa: 10 ÷ 50%.

• The kuotcha gulu: wosiyana ❖ kuyanika ndi Kuwonjezera wa reagents kuti kukweza katundu zili pansi makhalidwe ofunikira.
• Analimbitsa: Film Technology ndi mauna a polypropylene kapena polyethylene.
• Transparent: gwero zakuthupi - HDPE. Hydrophilic ethylene copolymer filimu bwino chilungamo.
• Mtundu: Zofunika - HDPE, colorants, stabilizers.

Polyethylene filimu zaumisiri: Mapulogalamu

The zosiyanasiyana mitundu amalola ntchito polyethylene pafupifupi muzochitika zones za zochita za anthu:

• Yomanga: mu mawonekedwe a wamanja kapena webs, makulidwe 60 ÷ 200 microns. Ntchito pallets CD ndi zipangizo chivundikirocho ndi kuteteza kali ku kuipitsidwa.

• Agriculture:

1. Film Technology pigment wakuda: yosiyanasiyana mapepala, kuphatikizapo zofunda "pansi nthunzi" mphukira (makulidwe 60 microns), mulching, kachulukidwe 10 ÷ 60 microns.
2. Hydrophilic ndi kuzikonzanso chilungamo: kuti greenhouses.

• wazolongedza:

1. Kuotcha filimu (malaya chinsalu) za pulayimale ndi sekondale, zipangizo mtengo yaiwisi.
2. Mu mawonekedwe a matumba: zinyalala CD ndi zinyalala.

Polyethylene filimu ali osiyanasiyana yaikulu ya luso, angathe kukwaniritsa chokhumba chilichonse cha wogula. The drawback chachikulu - ndi mkulu nthawi ya kuwonongeka kwa zinthu ndi mlingo wochepa wa processing.
