Isikhwama se-PE sisikhwama esiqhelekileyo kubomi bethu bemihla ngemihla, esetyenziselwa zonke iintlobo zeziqhamo kunye nemifuno yokupakisha, izikhwama zokuthenga, ukupakisha iimveliso zezolimo, njl njl. Ukwenza isikhwama sefilimu yeplastiki ebonakala ngathi ilula kunokuba nzima kakhulu. Inkqubo yokuvelisa ingxowa ye-PE ibandakanya amasuntswana eplastiki - ukuxuba ukutshatyalaliswa kobushushu - ukunwenwa kwe-extrusion - unyango lwe-elektroniki -; Ingxowa ye-PE ikakhulu ezi nkqubo ezininzi zingentla, zenziwe lula emva kweenkqubo ezintathu: ukuvuthela ifilimu ------ ukuprinta ------ ukwenza ibhegi.
Inkqubo yoshicilelo bag PE kufuneka ingqalelo yintoni?
I-Polyethylene, ukumelana nobushushu obuphantsi (ukusebenzisa ubushushu ukuya kuthi ga -70 ~-100), ukuzinza kweekhemikhali, ukhukuliseko lwe-asidi eninzi kunye ne-alkali (enokunganyamezeli kwe-oxidizing acid), enganyibilikiyo kwi-solvents ngokubanzi kwiqondo lokushisa, ukufunxa okuphantsi, ukusebenza kakuhle kombane wokugquma. Nangona kunjalo, i-polyethylene ivakalelwa kuxinzelelo lwendalo (ikhemikhali kunye nesenzo soomatshini) kwaye ihlupheke ekugugeni kobushushu. Iimpawu ze-polyethylene ziyahlukahluka kwiintlobo ukuya kwiintlobo, ngokukodwa kuxhomekeke kwisakhiwo se-molecular and density. Iimveliso ezinobunzima obuhlukeneyo (0.91-0.96 G / CM3) zinokufumaneka ngeendlela ezahlukeneyo zokuvelisa. I-polyethylene inokucutshungulwa ngeendlela eziqhelekileyo zokwenza i-thermoplastic (jonga i-Plastiki processing).
Ngawaphi amanqaku anxulumene nenkqubo ngokweenkcukacha ezingezantsi?
Inkqubo yokuvuthela ifilimu kufuneka inikele ingqalelo kula manqaku alandelayo:
1. Umlinganiselo wezinto eziluhlaza: ngokweemfuno ezahlukeneyo zeengxowa ze-PE, ukulungiswa kwemilinganiselo eyahlukeneyo yezinto eziluhlaza. Umzekelo: i-anti-static, i-anti-rust, inciphisa, i-conductivity yombane, i-biodegradation kunye nezinye iimfuno, zongeza iintlobo zezongezo ezincedisayo umzekelo: ukusebenzisa obomvu, omnyama, umbala kunye neminye imibala, yongeza iindidi zemibala enemibala. Ngokusekuhleni, ukuqina, amandla okukrazula, ukutsalwa kwevacuum kunye nezinye iimfuno, kuthatha indawo yeempawu ezahlukeneyo okanye iimveliso ze-PE. Umzekelo: ngokweemfuno ezizodwa, gxininisa iimfuno zokungafihli okuphezulu, ukukrazula okuqinileyo, ukuvuleka okuhle, ukuze utshintshe umlinganiselo wezinto eziluhlaza.
2.inkqubo yokuvuthela ifilimu yoshicilelo, imfuno yokulungiswa kombane, ngeli xesha ukunikela ingqalelo kumandla ombane wombane, ukuqinisekisa ukuba i-PE drum material electronic processing power (DAYIN) ngokwaneleyo ukuqinisekisa ukunamathela kwe-inki.
3.kwinkqubo yokuvuthela ifilimu, ngokweemfuno ezikhethekileyo zefilimu, ukuvulwa okukodwa, ukuvulwa kabini, ukugoqa, ukutshatyalaliswa kwendawo yoxinzelelo, i-embossing, ukwandiswa kunye neminye imisebenzi.
Inkqubo yoshicilelo lwengxowa ye-PE kufuneka ithathele ingqalelo le miba ilandelayo:
I-1.inki yokushicilela: i-inki esekelwe emanzini, i-inki yokumisa ngokukhawuleza, i-inkino engabonakaliyo, i-inki eguqula umbala, i-anti-counterfeiting inki, i-induction inki, i-conductive, i-electronic ephantsi, i-matte inki kunye nezinye iimpawu ze-inki.
2. Ipleyiti yokushicilela: ngokweemfuno ezintle zomxholo wokushicilela, i-gravure (ipleyiti yobhedu) yokushicilela kunye ne-flexography (offset) yokushicilela isetyenziswa. Ezi ndlela zimbini zokushicilela zahlukeneyo.
3. Ngokutsho kobunzima bomxholo wokushicilela kunye nobunzima bombala, khetha indlela yokushicilela: ukuprintwa kwe-monochrome, ukuprintwa kwe-monochrome kabini, ukuprintwa kombala omnye, ukuprintwa kombala ophindwe kabini.
4. Ngokweemfuno ezikhethekileyo zeepateni zokuprinta, ngokweempawu zokuchithwa kwemibala, i-anti-counterfeiting, i-conductivity yombane, i-adhesives kunye nokunye, khetha inki ezahlukeneyo okanye izongezo.
