Yolula ifilimuikakhulu imveliso ekhuselayo kwaye inokubonelela ngokhuseleko lomhlaba kwimveliso. Ifom yemveliso ilula kakhulu, ukukhusela ngokuchasene nokubonakala kothuli, ioli, kunye nokufuma, ukungangeni kwamanzi, kunye nokuchasana nobusela. Ifilimu ekhuselayo yokupakisha iyakwazi ukulungiswa ngexesha elifanayo ukunyanzeliswa kunokwenziwa ukwenza imveliso ngokuqinileyo. Iimveliso ezithambileyo, ngakumbi kwishishini lecuba nakwishishini lempahla yamalaphu, zinefuthe elikhethekileyo lokupakisha. Abavelisi befilimu abalandelayo baya kukuxelela ukuba uthenge ifilimu eyolulayo ekumgangatho ophezulu. Ziziphi iindlela?
Okokuqala, jonga elubala kwaye ulinganise amandla okuqina.
Okokuqala ukusuka kubude befilimu eyolulayo ecaleni kwendlela yokukrazula, kwaye emva koko ukusuka kwicala elithe tyaba lokukrazula, ukolulwa kwefilimu eyoluliweyo enamandla okuqina kwempembelelo yayo yomelele. Umgangatho olungileyo owoluliweyo wefilimu unokufikelela kwi-100% -300%. Indlela yokuvelisa imveliso iye yaphuhliswa ukusuka kwi-single-layer ukuya kwi-two-layer kunye ne-three-layer, kwaye ngoku indlela yokuphosa isetyenziselwa ukuvelisa ifilimu eyolulayo ye-LLDPE. Oku kungenxa yokuba ukuveliswa komgca we-cast line inzuzo yobukhulu obufanayo, ukucaca, njl., Enokuthi isetyenziswe kwiimfuno zezinga eliphezulu lokunweba kwangaphambili. Ngenxa yokusatywa kwe-single-layer engenzekiyo kwelinye icala lezinto ezincangathi, iindawo zesicelo zilinganiselwe. I-single- kunye ne-double-layer cast in the choice of information is not wide as three-layer cast, kunye nefomyula inzala nayo iphezulu, ngoko ke isakhiwo esine-co-extruded isakhiwo sisalungile. Ifilimu eyoluliweyo ekumgangatho ophezulu kufuneka ibe nokungafihli okuphakamileyo, ubude bobude obuphakamileyo, indawo enesivuno esikhulu, amandla anqamlezayo okukrazula, kunye nokusebenza kakuhle kokugqobhoza.
Okwesibini, ukulinganisa ubukhulu, jonga ukuba ifilimu inamancinci amancinci, kwaye ulinganise amandla okuqina.
I-Crystal point yingxaki yekhwalithi eqhelekileyo yezinto zefilimu ezolula; jonga ukuba kukho amasuntswana kumphezulu wefilimu eyolulayo. Inqaku leCrystal yindawo yefilim eyolulayo yaloo mingxuma mincinci, eyaziwa ngokuba ngamabala aqaqambileyo; ubukhulu becala kuluhlu lwefilimu enezintlu ezintathu eziqhelekileyo. Isizathu esiphambili kungenxa yokusetyenziswa kwe-silica gel synthesis; ijeli ye-silica inokuhamba; ukuba ubuso befilimu eyolulayo budibene neencinci ezincinci ze-extrusion, beziya kwenza i-crystal point ukuphepha i-crystal point yendlela, oko kukuthi, ukukhusela ubuso befilimu yokwelula.
Ukupakishwa kwefilimu yokwelula kwenza ukuba izinto ezipakishweyo zibe noxinzelelo olufanayo, ukuphepha ukungalingani okukhokelela ekulimaleni kwempahla, okuyindlela yokupakisha yendabuko (i-bundling, wrapping, taping, etc. ukupakishwa akunakukwazi). Ukusonga ukuziphatha kwefilimu kunye nokuhlehla, i-compact, i-tape esisigxina inokuvelisa njengeyunithi, i-dispersion yonke incinci, nakwiindawo ezingathandekiyo iimveliso azinakho ukukhulula kunye nokwahlula, akukho macala abukhali kunye nokuncamathela ukuphepha ukwenzakala.
Ukongeza, kukho ifilimu eyoluliweyo kunye nefilimu eyoluliweyo evuthelweyo.
Yenza ifilimu elula
Ifilimu eyolulayo yeCast eyenziwe ngenkqubo yokwenziwa eqhubekayo ibalasele ngokucaca kwayo kunye nokugudiswa kwayo. Ifilimu yeCast iphawuleka ngokuphumla kwayo okuthe cwaka kunye nokumelana nokukrazula okugqwesileyo okugcina uzinzo olubalaseleyo lomthwalo. Ifanelekile kwizicelo ezifuna ukucaca okuphezulu kunye nokusebenza okungaguqukiyo ngelixa ihlala ibiza imali kwaye iguquguqukayo, iyenza ibe lukhetho oludumileyo kuwo wonke amashishini.
ifilimu yolula evuthelweyo
Ngokwahlukileyo, ifilimu eyolulayo evuthelweyo ingena kwinkqubo enzima yabasebenzi ebandakanya i-extrusion kunye nokupholisa kwaye inikezela ukuxhathisa okuphezulu kunye namandla kunefilimu ephosiweyo. Ukomelela kwefilimu evuthelweyo kuyenza ilungele imithwalo enzima okanye emile kakuhle efuna ukomelezwa okomeleziweyo kunye nokumelana nokukrazula, oko kuyenza ibe lolona khetho lubalaseleyo kwimingeni yokupakisha.
Intshatsheli yeXHngumenzi wefilimu owolulayo oyingcali kunye nomboneleli wesisombululo; ukusombulula iingxaki zokupakisha zabathengi yeyona njongo yethu iphambili.Qhagamshelana nathingoku ukwenza ngokwezifiso ifilimu yakho yokupakisha.
