isicelo

Ukolulwa kwefilimu ngokuqhelekileyo kusetyenziselwa iifilimu ezilastiki ezininzi zepolyethylene, ezenziwe kusetyenziswa itekhnoloji yefilimu yokukhulisa ifilimu ebizwa ngokuba yi "CAST".Ifilimu ithetha ukuba uluhlu oluncinci lwezi zinto lunokuhambelana ngokuchanekileyo kunye nokuguquguquka okuphezulu.
Ifilimu eyoluliweyo yifilimu yeplastiki enoluleka kakhulu eyenziwe nge-polyethylene (PE) esekelwe kwizixhobo kwaye isetyenziselwa ukusonga i-pallet ukuze ikhusele ukulayishwa kokuphathwa ngokufanelekileyo kunye nokugcinwa.
I-linear low-density polyethylene (LLDPE) sisiseko sezinto zokubonelela ngefilimu.Iifilimu zethu zinomgangatho ophezulu kakhulu ngenxa yeyona migca yemveliso yala maxesha kunye neteknoloji ephezulu kakhulu, kunye nokusetyenziswa kwezinto ezibonakalayo ezibonelelwa ngabavelisi abaziwayo.Uluhlu olwandisiweyo lweefilimu ze-polyethylene zilungiselelwe ukusuka kwi-low density Polyethylene metallocene resins) m- LLDPE), i-linear low-density polyethylene (LLDPE) kunye ne-ultra-low-density polyethylene (ULDPE) equkethe i-0 kunye ne-8% ye-polyisobutylene (PIB).
Isicelo
Ifilimu eyolulayo isetyenziselwa ukusonga kunye nokukhusela imithwalo epakishwe kwiipalethi kwizinto zomntu ngamnye ezinobukhulu obukhulu, ukusebenzisa ifilimu eyolulayo yeyona ndlela isebenzayo yokupakisha kunye nokusonga iimveliso ngenxa yobunzima obuphantsi kunye nokuqina okuphezulu okuqinisekisa ukuzinza komthwalo. .
Yolula ifilimu / usonga Amandla amakhulu kunye namandla
Ubukhulu befilimu obuveliswayo buyilwe ukusuka kwi-10 ukuya kwi-35 yeemicrometer zokusonga kunye nokukhusela iimveliso zisebenzisa oomatshini bokupakisha.Ububanzi befilimu obuqhelekileyo: 500 mm, kuyafezekiswa ukuvelisa enye ifilimu yobubanzi ngokuphindaphinda kwe-250 mm.
Yintoni ifilimu eyolula?
Ifilimu eyoluliweyo yifilimu yeplastiki ecekethekileyo, eyongeziweyo (eqhele ukwenziwa ngepolyethylene) esetyenziselwa ukutshixa kunye nokubopha izinto ezikhuselayo kwiipalethi.Njengoko ifilimu eyolulayo isongelwe kwi-pallet, i-tension iyadalwa kwaye yenza ukuba ifilimu ikhulise ubude bayo ukuya kumaxesha angama-300.Olu xinzelelo ke ludala amandla ekhontrakthi ajikeleze umthwalo kwaye uwugcine ungatshintshi kwindawo yawo.
Iindidi zeefilimu ezolula
Kukho iintlobo ezimbini eziphambili zefilimu eyolula: ifilimu eyolulayo yezandla kunye nefilimu eyolula yomatshini.
1. Ifilimu yokwelula ngesandla
Ifilimu eyolulayo ye-manual yenzelwe ngokukodwa ukusetyenziswa ngesandla kwaye ngoko idla ngokusetyenziswa kwivolumu ephantsi kwimisebenzi yokupakisha kunye nokusonga.Kuye kwaqwalaselwa ukupakishwa ngesandla.Ubunzima befilimu eveliswayo buvela kwi-10 ukuya kwi-40 micrometers kunye nobubanzi buyi-450 mm okanye i-500 mm, i-tensile 100% iqinisekisiwe.Ifilimu iveliswe koomatshini abazenzekelayo abaxhotyiswe ngamaziko alawula ubude kunye nobunzima befilimu ekuluhlu.
2. Umatshini wokolula ifilimu
Ifilimu eyoluliweyo yomatshini yifilimu eyenzelwe ngokukodwa ukusetyenziswa koomatshini bokutsala kwaye idla ngokusetyenziswa kumthamo omkhulu wokupakisha kunye nemisebenzi yokusonga.Ezinye iintlobo eziqhelekileyo zoomatshini befilimu abalula ziquka:
-Ifilim evuthelweyo yoLula-Yenziwa kusetyenziswa inkqubo yokukhupha umoya.Le nkqubo ibandakanya ukuvuthela i-resin ezivuthayo kwi-bubble.I-bubble ke ijika ibe ngamashidi agqitywe kwaye afakwe kwi-tube engundoqo.
Ifilimu yeCast Stretch-Yenziwa kusetyenziswa inkqubo ye-extrusion.Le nkqubo ibandakanya ukondla i-resins evuthayo ngomgca we-roller epholileyo, emva koko iqinisa ifilimu.
Ifilimu eyolulwe ngaphambili- Yifilimu esele yandisiwe kwizigaba zemveliso.
