Plastic emikhonweni izici, isicelo

Okuvame kakhulu izinhlobo emaphaketheni eyenziwe ifilimu plastic. Kusukela kwenza ethandwa-shirts ezokugqoka nezikhwama bese Ukugoqa izinto zokukhiqiza. Nokho, ngokuya lula, ukhetho best kuyinto iphakethe-emkhonweni. zako zihlanganisa kungenzeka ngokusebenzisa ubude ezahlukene impahla. Lokho, kwezinye izindlela umsebenzisi ziyahlukahluka kwemigomo iphakethe. Ngesikhathi esifanayo, emkhonweni plastic azigcina zonke izinzuzo amaphakheji zakudala, okuhlanganisa ukuqina, kalula ukuphatha ukuqinisekisa yobunzima.

Lapho kufanelekile emkhonweni of polyethylene?

Le filimu kunesisekelo sokubonisa okwengeziwe yokukhiqiza amaphakheji. Ngakho-ke, kungashiwo ngokuthi jikelele. Isikhwama kungaba umkhiqizo consumable embonini yezokwakha, ekuhlinzekeni iIgama izindawo futhi kumnotho wasekhaya. Ngokuvamile, a se plastic upakisha lisetshenziswe izicelo lapho okufanele ukusebenza esiningi umkhiqizo noma lezimpahla. Ngokwesibonelo, lokugoqa izinto ngobuningi. Ukungabi bikho seams evelele kanye perforations ikuvumela ukuba ahlele othomathikhi emaphaketheni line, eyayinqamula akudingi opharetha uxhumano.

Zifakwe ifilimu e ngesimo imikhono futhi ezindaweni ezikhethekile. Ngakho, kukhona polyethylene, okuyinto ekuqaleni yenzelwe ukusetshenziswa nezidingo zikagesi. Njengoba iphakheji kungenziwa isehlane amadivayisi kanye namadivayisi ukuze bazivikele umswakama. Futhi basakaza emikhonweni plastic izithombo, okuyinto sokukhula ngokuya nokuhlanzeka kwemvelo.

yokukhiqiza ubuchwepheshe

Nalapha futhi, i-polyethylene ekuqaleni kuyinto impahla eluhlaza for yokukhiqiza amaphakheji ne izibambo nezinye emaphaketheni ezikhethekile noma yasendlini. Umkhono we yena, - a esuselwe inqubo ingqikithi ekukhiqizeni izinto ifilimu. Ukuze ukukhiqizwa yayo Plastic elimbudumbudu Kusetshenziswa izinga izici ezithile. Kumiswa inqubo ukuncibilika is a emikhonweni plastic for evala ifilimu. Esikhathini esizayo, abakhiqizi bangase bahlukanise roll zibe izicucu, ukudala umkhiqizo lulwimi siphelile ukuba iphakethe egcwele nge izibambo.

Ukuze kwandiswe amandla abakhiqizi nanesandla isakhiwo eyinhloko ekhethekile izithasiselo, modifiers futhi plasticizers. Ngenxa yalokho, a se plastic lithola eqine amandla ephakeme izinga. Futhi, senqubo yokukhiqiza kungafaka isicelo ukunyathelisa futhi ukudalwa isaphulelo ifaka. Kodwa le misebenzi ngokuvamile eyenziwa oda ekhethekile.

izici

Kanye ubude emaphaketheni akuyona ngokuvamile fixed - emkhonweni ekhiqizwa ngendlela ebalulekile. Ngokuqondene nobubanzi, ifomethi ezijwayeleke kakhulu 20, 30 no-40 cm, nakuba kuye amakhono imishini osayizi ephasishi wande. Kumafilimu kakhulu embondelene ukujiya kwalo ebangeni 30-200 microns. Naphezu isakhiwo nomzimba omncane, emkhonweni plastic zingamelana imithwalo okusezingeni eliphezulu - emashumini ambalwa amakhilogramu. Kuyaphawuleka ukuthi izinto ekhiqizwa kusuka polyethylene ezase babe izingqimba mkhulu, futhi okuholela okusezingeni eliphezulu amandla izici.

izakhiwo okusebenza kwe-ifilimu

Njengoba kuphawulwe ngenhla, izici lobuchwepheshe polyethylene abazimisele ngezinga izithasiselo esikhulu okuyinto yethulwe ngesikhathi enza. Ikakhulu, i-ngokuhambisa modifiers impahla aninike aphansi Coefficient friction. Lokhu lula ukuvezwa imikhono, ifilimu inika kukhanye elithile, kodwa ngesikhathi esifanayo ukususa umphumela static. Ikakhulukazi ukuvimbela ababambelela odongeni kwangaphakathi impahla esetshenziswa njengoba antiblocking okufakiwe. With the kwalokho ifilimu hhayi kuphela kuqeda umphumela adhesion, kodwa uzuza ebusweni maholoholo. Okusatshalalisiwe futhi kusho sokuvikelwa zangaphandle, okuyinto kwahambisana ifilimu polyethylene. I-sleeve, esasetshenziswa esikhangisweni se ngokucubungula cishe yizona ezisetshenziswa kabanzi flame, isibonelo, ukumelana nomlilo. Isimiso umlilo ukucindezelwa yaqaphela ngokwethula egqinsiwe silicate inhlanganisela, okuyisisekelo ungqimba carbonaceous. Imiphumela iba yinhlanganisela yokukhandleka isithiyo engangenwa umlilo futhi ukukhululwa kwemikhiqizo oluyingozi ngesikhathi omlilo.

Lokho okwakudingeka ukuze kukhokhwe impahla

Ngokuvamile, abakhiqizi yakha amanani ngamunye, ukugxila kwemigomo ngeluhlelo lolutsite. Kuthinte izindleko kanye nosayizi kuwebhu, kanye ukushuba nokusebenza izakhiwo, afakwa ifilimu polyethylene. Inani roll ububanzi 15 kuya 150 cm ngokwesilinganiso 180-200 ruble ngalinye 1 kg. I ukujiya ziyahlukahluka kusuka microns 40 kuya 120. Ngenhla ifilimu obukhulu kungase kwandise inani layo likwenza ubone ngoba ruble angu-50. ikhilogremu ngayinye, kodwa okuningi kuncike umthamo oda.

Okusatshalalisiwe nemikhiqizo melkoformatnaya ngesimo ezinemikhono ububanzi 6 kuya ku-15 cm. Nge ifilimu ezinjalo zingase zimiswe izikhwama ezincane emaphaketheni amabhizinisi iIgama. Nokho, kukhona eziningi amabhizinisi zezimboni, asebenzisa melkoformatnaya polyethylene ifilimu. Intengo kulokhu kakade ruble 250-300 ngamunye 1 kg. Ukwandisa izindleko ngenxa yokuba yinkimbinkimbi ohlobo senqubo yokukhiqiza kanye nobubanzi ezincane.

isiphetho

Ukusebenzisa okokusebenza esiwusizo sokuba nezinto eziqondile polyethylene ne anganikeza isivikelo mechanical kuya umkhiqizo futhi awuvikele ukuchayeka okushisa aphakeme kanye nomswakama. Ngesikhathi esifanayo onjiniyela balwela ukuthola ukusebenza entsha umkhiqizo ngenxa modifiers ngcono. Ikakhulukazi, uma uhlela ukusebenzisa emikhonweni plastic ezindaweni elangeni, kufanele sinake okuqukethwe isakhiwo stabilizers ukukhanya. Ngakho, uma ifilimu kuthengwa ukuze zimboze abamba ukushisa, bese uvula ilanga ngeke ukulimaza enamathela refractory. Ngakolunye uhlangothi, ukuba zikuvikele kuyaqina namandla ngaphansi kwamazinga okushisa aphansi kumele kusetshenziswe ifilimu lapho Ukwakheka izithasiselo abandayo nemithi anikezwa.
