1.PE Inkcazo yeFilimu yoLulelela
Ifilimu ye-PE (ekwabizwa ngokuba yi-stretch wrap) yifilimu yeplastiki eneempawu zokuzibamba ezinokuthi zolulwe kwaye ziboshwe ngokuqinileyo kwiimpahla, mhlawumbi kwicala elinye (i-extrusion) okanye macala omabini (avuthelwe).I-adhesive ayihambelani nomphezulu wempahla kodwa ihlala phezu kwefilimu.Ayifuni ukunciphisa ubushushu ngexesha lenkqubo yokupakisha, enceda ukugcina amandla, ukunciphisa iindleko zokupakisha, ukuququzelela ukuthuthwa kwesikhongozeli, kunye nokuphucula ukusebenza kakuhle.Ukuhlanganiswa kweepallets kunye ne-forklifts kunciphisa iindleko zokuthutha, kwaye ukukhanya okuphezulu kuququzelela ukuchongwa kwempahla, ukunciphisa iimpazamo zokusabalalisa.
Iinkcukacha: Ububanzi befilimu yomatshini 500mm, ububanzi befilimu yesandla 300mm, 350mm, 450mm, 500mm, ubukhulu be-15um-50um, bunokunqunyulwa kwiinkcukacha ezahlukeneyo.
2.Ukuhlelwa kokusetyenziswa kwefilimu eyoluliweyo yePE
(1)Umboniso bhanyabhanya owolulela ngesandla:Le ndlela isebenzisa ubukhulu becala ukupakishwa kwencwadi, kunye nefilimu eyolulayo ngesandla ngokubanzi ineemfuno zomgangatho ophantsi.Umqulu ngamnye unobunzima obumalunga ne-4kg okanye i-5kg ukuze usebenze ngokulula.
(2)Ifilimu eyolulwe ngoomatshini:Ifilimu eyolulayo yomatshini isetyenziselwa ukupakisha ngoomatshini, ikakhulu iqhutywa kukuhamba kweempahla ukufezekisa ukupakishwa.Ifuna amandla aphezulu kunye nokunwebeka kwefilimu.
Ireyithi yokwelula ngokubanzi yi-300%, kwaye ubunzima be-roll yi-15kg.
(3)Ifilim yoMtshini Wokolulwa kwangaphambili:Olu hlobo lwefilimu olulula lusetyenziselwa ukupakisha ngoomatshini.Ngexesha lokupakisha, umatshini wokupakisha uqala ukunweba ifilimu ukuya kumlinganiselo othile kwaye emva koko uyisongele malunga neempahla eziza kupakishwa.Ixhomekeke kwi-elasticity yefilimu ukupakisha iimpahla.Imveliso inamandla aphezulu okuqina, ubude, kunye nokumelana nokugqabhuka.
(4)Ifilimu enemibala:Iifilimu ezilula ezinemibala zifumaneka ngeblue, red, yellow, green, and black.Abavelisi bazisebenzisa ukupakisha iimpahla ngelixa besahlula phakathi kweemveliso ezahlukeneyo, besenza kube lula ukuchonga iimpahla.
3.Ukulawulwa kwe-PE Stretch Film Adhesiveness
Ukubambelela okulungileyo kuqinisekisa ukuba iileya zangaphandle zefilimu yokupakisha zihambelana nomnye, zibonelela ngokukhuselwa komhlaba kwiimveliso kunye nokwenza i-lightweight engaphandle ekhuselayo malunga neemveliso.Oku kunceda ukuthintela uthuli, ioli, ukufuma, amanzi, nobusela.Okubalulekileyo, ukupakishwa kwefilimu ngokulinganayo kusasaza amandla ajikeleze izinto ezipakishiweyo, ukuthintela uxinzelelo olungalinganiyo olunokubangela umonakalo kwiimveliso, ezingenakufezekiswa ngeendlela zokupakisha zendabuko ezifana nokubopha, ukubopha, kunye ne-tape.
Iindlela zokufezekisa ukubambelela ngokukodwa zibandakanya iindidi ezimbini: enye yokongeza i-PIB okanye i-master batch yayo kwi-polymer, kwaye enye kukudibanisa ne-VLDPE.
(1) I-PIB yi-semi-transparent, i-viscous liquid.Ukongezwa ngokuthe ngqo kufuna izixhobo ezikhethekileyo okanye ukulungiswa kwezixhobo.Ngokubanzi, PIB masterbatch isetyenziswa.I-PIB inenkqubo yokufuduka, edla ngokuthatha iintsuku ezintathu, kwaye ikwachatshazelwa bubushushu.Inokubambelela okuqinileyo kumaqondo aphezulu kunye nokunyathela okuncinci kumaqondo aphantsi.Emva kokwelula, ukunamathela kwayo kuncipha kakhulu.Ngoko ke, ifilimu egqityiweyo igcinwe kakuhle kwiqondo elithile lokushisa (iqondo lokushisa elicetyiswayo lokugcinwa: 15 ° C ukuya ku-25 ° C).
(2) Ukuxuba kunye ne-VLDPE kunokuncamathela okungaphantsi kancinane kodwa akufuni zixhobo zikhethekileyo.Ukuncamathela kuzinzile, akukho phantsi kwemiqobo yexesha, kodwa kukwachatshazelwa bubushushu.Iyancamathela noko kumaqondo obushushu angaphezulu kwama-30°C kwaye incamathele kancinci kumaqondo obushushu angaphantsi kwe-15°C.Ukulungelelanisa inani le-LLDPE kwi-adhesive layer inokufikelela kwi-viscosity efunekayo.Le ndlela isoloko isetyenziselwa iifilimu ze-co-extrusion ezinemigangatho emithathu.
4.Iimpawu ze-PE Stretch Film
(1) Umanyano: Le yenye yezona mpawu zinkulu zokupakishwa kwefilimu eyolulayo, ebophelela ngokuqinileyo iimveliso kwi-compact, iyunithi esisigxina, naphantsi kweemeko ezimbi, ukuthintela nakuphi na ukukhulula okanye ukwahlukana kweemveliso.Ukupakishwa akunayo imiphetho ebukhali okanye ukunamathela, ngaloo ndlela ugwema umonakalo.
(2) Ukukhuselwa okuPhambili: Ukhuseleko oluphambili lubonelela ngokukhuselwa komhlaba kwiimveliso, ukudala ingaphandle elikhuselayo elikhuselayo.Ikhusela uthuli, ioli, ukufuma, amanzi, nobusela.Ukupakishwa kwefilimu ngokulinganayo kusasaza amandla ajikeleze izinto ezipakishiweyo, ukuthintela ukufuduka kunye nokuhamba ngexesha lokuthutha, ngakumbi kumashishini ecuba kunye nempahla yelaphu, apho ineempembelelo ezizodwa zokupakisha.
(3) Ukugcinwa kweendleko: Ukusebenzisa ifilimu eyolulayo yokupakisha imveliso kunokunciphisa ngokufanelekileyo iindleko zokusetyenziswa.Ifilimu eyolulayo idla kuphela malunga ne-15% yebhokisi yebhokisi yokuqala, malunga ne-35% yefilimu yokunciphisa ukushisa, kunye ne-50% yebhokisi yebhokisi yebhokisi.Ikwanciphisa amandla okusebenza, iphucula impumelelo yokupakisha, kwaye iphucula amabakala okupakisha.
Isishwankathelo, indawo yokusetyenziswa kwefilimu eyoluliweyo ibanzi kakhulu, kunye nemimandla emininzi yaseTshayina ekusafuneka ihlolwe, kwaye iindawo ezininzi eziye zahlolwa ayikasetyenziswa ngokubanzi.Njengoko insimu yesicelo isanda, ukusetyenziswa kwefilimu eyolulayo kuya kwanda kakhulu, kwaye amandla ayo okuthengisa angenakulinganiswa.Ngoko ke, kuyimfuneko ukukhuthaza ngamandla ukuveliswa kunye nokusetyenziswa kwefilimu elula.
5.Izicelo ze-PE Stretch Film
Ifilimu eyolulayo ye-PE inamandla aphezulu, ukumelana nokukrazula, ukungafihli, kunye neempawu ezibalaseleyo zokubuyisela.Ngomlinganiselo wangaphambili wokwelula we-400%, ingasetyenziselwa ukugcinwa kwesitya, ukunqanda amanzi, ukutshatyalaliswa kothuli, ukusabalalisa, kunye neenjongo zokulwa nobusela.
Ukusetyenziswa: Isetyenziselwa ukusonga i-pallet kunye nokunye ukupakisha kwaye isetyenziswa ngokubanzi kurhwebo lwangaphandle, ibhotile kunye nokuvelisa, ukwenza iphepha, i-hardware kunye nezixhobo zombane, iiplastiki, iikhemikhali, izinto zokwakha, iimveliso zezolimo, ukutya kunye namanye amashishini. .
