Shwabanisa ifilimu upakisha: inkcazelo kunye neentlobo

Nophuhliso entsimini kobuchwepheshe yemichiza ukuphucula imveliso yawo. Kakhulu ingxenye kwicandelo ekupakisheni izinto, ngayo nabenzi nonfood kunye nokutya iimveliso nokugcina iimpawu zazo kunye nokusebenza. ithandwa enkulu wafumana umboniso nciphisa zokuphakheja, ifoto leyo ithiwe thaca apha ngasezantsi.

Iimpawu Shwabanisa film

Umahluko omkhulu Shwabanisa ifilimu ukukwazi kwalo nciphisa ukuya ubungakanani elihambisana into ekujoliswe kulo. ucinezelo yayo kwenzeka phantsi amaqondo obushushu aphezulu. Emva okupholisa, impahla kuthatha uhlobo lwemveliso olupakishiweyo. Ngenxa yoko, le filimu sofinyela nokubopha ungagcina iimpawu zobugcisa ngokwasemzimbeni kweemveliso ezahlukeneyo, kuquka ukwakhiwa kunye nokutya.

Kuxhomekeka umda wokusetyenziswa abenzi ukunika ezinye iifitsha zibe film. Umzekelo, i-apertured umboniso lukhutshwe ukuba iimveliso yokubhaka. Isiseko umbandela olufanayo ekrwada izenzo PVC okanye zithutha polyolefin. Ukuba PVC ngokwemveli kwemfuneko ngenxa iyahlala yayo, i pof kusilungele, kuba akukho ukungcola eziyingozi. Ngokuqhelekileyo, le filimu sofinyela iibhotile ekupakishweni okanye izikhongozeli ukutya kuveliswe ukusuka material polyolefin.

film application

Kuxhomekeka indices Shwabanisa bhanya kunye nende zisetyenziselwa iinjongo ezahlukeneyo. Ngoko ke, ukuba iqondo encinci nokubotshwa, impahla isetyenziselwe iimveliso ezithambileyo izihlunu, iimveliso eziprintiweyo okanye iimveliso zokutya. Ngokwahlukileyo koko, shrinkage ngqongqo kuvumela ukwenza izinto zokwakha enzima, kwakunye iimveliso kunye neefom ezingekho semgangathweni. Amayela akayeki umboniso upakisha izinto ezinkulu equka iqela iqela, ukholosile ukulungisa nabo sisendleleni. Hi ndlela leyi, kuba eyimveliso enjalo umboniso Polyvinyl chloride uyasetyenziswa. Kubalulekile ukuqaphela ukuba ukongeza zokuzikhusela kunye nokugcwaliswa umsebenzi ifilimu zingasetyenziswa uyilo obonakalayo imveliso. Nokupakishwa akayeki idla lisongelwe iphepha lodongo, izinto zokudlala, iimagazini, enika imveliso ye ayenechaphothi extra ukhanye.

iimpawu ezibonakalayo

Le filimu ifumaneka iifomati ezahlukeneyo, nto leyo iyohluka, ngokuxhomekeke kumatshini nokupakishwa. Ngokuphathelele ukukhetha imveliso ethile, kufuneka sinikele ingqalelo iimpawu ezimbini - ipesenti shrinkage nezinyuko. Ngokuqhelekileyo, ipesenti shrinkage kwi kumgca longitudinal zomyalelo 60-70%, kwaye kwicandelo cross - 10 ukuya kwi-50%. Ngomhla ngamandla ebekupakishwe iphembelela ubukhulu. Le film thinnest ngenxa Shwabanisa ukupakisha, wenza ngokwemigangatho zenkqubo zobuchwepheshe, kukho Ebubanzini microns-10. ukwahluka High ungaba kuze microns 200. Ngaphezu koko, kuyimfuneko ukuba bakuthathele ingqalelo iimeko lobushushu apho izinto ezinokusetyenziswa. Inyoba komndilili weqondo lobushushu avumelekile sivela -40 ukuya +50 ° C, nangona ngokuxhomekeka ubuchule isicelo kongeza izinto ezithi ekuphuculeni eli banga.

iipropati yokusebenza

Kukho zesiseko iimpawu yababephethwe phantse zonke iinguqulelo nciphisa iifilimu. Kwindawo yokuqala ngayo amandla aphezulu ngomatshini ukufanela ukuphakheja quality olukhuselayo. Kwakhona, le hlobo nto iphawulwa indibanisela bhetyebhetye kunye nokungafihlisi. Ukumelana kuseko amanzi yinto enye kwaye nokumelana ukufuma nazo ekwandiseni amathuba okuba kusetyenziswe lo mboniso.

Kakade ke, ipropati phantse unique, nto leyo iba umboniso nciphisa nokubopha, kukuba uyakwazi ukutshintsha indlela yomgama parameters uthabathe imilo imveliso target. Enye into kukuba ke ifuna izixhobo ezikhethekileyo, eyenza i yokugoqa. Kodwa exineneyo compact usempilweni elizayo iza kunika iingenelo ezimbini ezibalulekileyo. Okokuqala, uya kunikwa nokhuseleko emnyango, yaye okwesibini, kwinkqubo yokuthutha impahla iqela liya kuthatha ubuncinane isithuba. Ukuba sithetha kwiipropati ngabanye, phakathi kwazo ezi ukhuseleko lokusingqongileyo kunye nenkangeleko entle. Ezi mpawu isicelo ukuguqulwa ekhethekileyo imveliso lwemiboniso bhanya-bhanya.

uhlobo

Nangona ezininzi izinto ifilimu ithuba ubushushu-setting khangela ngokufanayo, kuba kukho umahluko. Technologists zihlelwa ukuphakheja ngohlobo isakhiwo, yokuqaqadeka, ubukho modifiers ezithile ekwakhiweni, ubukhulu, imilo, yaye ke mba. D. Enye yezona zinto ebalulekileyo ukuhlukana uhlobo lwesakhiwo. Eyona engcono kakhulu ukuba ukusebenzisa kucingwa ukuba cross-bhanya ilaphu nemixawuka. Akunamsebenzi ukubeka ingxelo ngokwemiqathango ngamandla, kodwa isakhiwo sayo waphawula ukulingana ngokugqwesileyo amalaphu ubukhulu kunye uqine. Lo mhlaba kubalulekile ukuba, umzekelo, sisetyenziselwa Shwabanisa umboniso diphu ingaphakathi imithamo emikhulu. Phambi ekukhonzeni abasebenzi kulo mzekelo, umsebenzi wokulondoloza isithuba iphezulu efumanekayo kwaye kwangaxeshanye kuqinisekiswe ukuthembeka ifilimu ngokwayo. Ngokubhekiselele iiyantlukwano ekwakhiweni, ngoko ke izinto ekwanti, nto leyo ziqulathe hydrochloride iirubber, istro, polyamide kunye ezifana. D. ingqalelo eyodwa unikwa kucalulo yi nenani lamanqanaba zefilim.

Le multilayer kunye monolayer film

Okokuqala, kufanele kuqatshelwe ukuba umahluko ezisisiseko zigqitywa indlela lemveliso. Single-Umaleko laphu yenziweyo indlela extrusion, ngamanye atsho ubunzima zeplastiki. Ngaloo ndlela eziluncedo afunyenwe mveliso ziquka viscosity ukwanda, luthambe, kwakunye nokwenza izinto elubala. Kodwa ukuba ukhetha ukuyishwabanisa umboniso for ukupakisha kwezitena okanye ezinye izinto zokwakha, kungcono ujonge betye multi-umaleko. Loo nto iveliswa coextrusion buciko. Umahluko omkhulu inkqubo yokuvelisa ukuba intloko evelisa extruders ethile esetyenzisiweyo. Multi-sangqa web iquka lokusekwa copolymer kunye asidi uguqulo kancincane kunye copolymer ethylene. isakhiwo ifilimu kuquka kwiiseli ezininzi olongezelelweyo.

nokupaka uqwalaselo

ezahlukeneyo ezahlukileyo imveliso nokupakishwa Shwabanisa umboniso, ukhetho yayo emiselwe iimpawu mveliso. Ngokukodwa, isebenzisa enye, iqela kunye nokupakishwa eDibanisa. Le ukhetho lokuqala lisetyenziselwa ukusebenza kunye iimpahla piece - nokupakishwa ekuthiwa-ngamnye. indlela Group olusetyenziswa izixhobo enye imveliso eziliqela kunye ezineempawu ezifanayo mbini. Ngokomzekelo, omnye uqwalaselo onjalo ivumela umboniso nciphisa ukuba diphu pallets ukuba pre-Bha eDibanisa okuninzi kwi zeendawana okhethekileyo. Ukongezelela ukugcina loo indlela sopakisho yenza yokuthuthwa emyoli ekhuselekileyo kweempahla. uqwalaselo eDibanisa okuninzi kwakhona ibonelela ukuba ukusetyenziswa pallet, kodwa oluphuculweyo ukuqina. Olu khetho efanelekileyo ukulawula uluhlu olubanzi iimveliso: ukusuka iinkonkxa kunye neencwadi ukuba izitena neebhegi. Emva ingqokelela iimpahla kuhlawulwa yi-inshorensi lwemiboniso bhanya-bhanya.

ifomu Ukukhululwa nokumakishwa

Ukulungiswa ifilim isilonda izingxobo ezikhethekileyo yaye iza ngohlobo rolls. Ngaphezu ngokubhijela nganye nayo ezihlawulelwayo esingxotyeni salo olukhuselayo ezenziwe ngephepha okanye polyethylene efanayo. Ngokuqhelekileyo, le Shwabanisa film ilingana uluhlu umntu ububanzi 500 mm kwaye inobunzima-35 kg. Noko ke, kushishino kunye necandelo lokuvelisa izinto ezisetyenzisiweyo, kunye nezinye neefomathi ezahlukeneyo, umzekelo, ububanzi 1000 mm kunye nobunzima 50 kg. roll ngasinye mfuneko iphawulwe inkampani equlethe ulwazi malunga nomenzi, iinkcukacha imveliso, umhla ukukhululwa, njl Xa ukhetha iimveliso filimu kufuneka afumane ulwazi malunga iimvavanyo - .. Ulwazi iimpawu kunye nezakhono zokusebenza kuya kunceda kuthenga sopakisho ngeyona ndlela inenzuzo enkulu efanele iimfuno ezithile.

isiphelo

iimveliso upakisha market obanzi kakhulu, nto leyo kungenxa isidingo esikhulu iimveliso kweli qela. upakisha Umgangatho kufuneka namhlanje kwiinkalo ezahlukeneyo: zokulungisa ukutya kwakunye neevenkile. Njengoko lo mkhuba ubonisa ukusetyenziswa kwezinto ubushushu-nciphisa, malunga 90% yale yemveliso isetyenziswa inkonzo impahla non-ukutya. Noko ke, ukwanda ukhuseleko lokusingqongileyo kunye amathuba okwandisa ukusetyenziswa zizinto ebekupakishwe kuzo imifuno, iimveliso yokubhaka, iimveliso semi-igqityiwe njalo njalo. D.

Ukuphuculwa film shwabana ngenxa ukuphakheja kwempahla ezimalunga nokhuseleko. Ukuqina, ukumelana iinyembezi kunye yengxinano - ezi mpawu zibaluleke kakhulu ukugcinwa zokwakha, apho -. Iwolphepha, amanqaku kufanelekile, tile, panel lining, njl Kwakhona, kukho isimo ukwanda kwemfuno iifilimu ezobuchwepheshe iinguqulelo zibonelela iipropati yokusebenza olongezelelweyo.
