Ukuveliswa iingxowa ezinepolypropylene: ubuchwepheshe kunye nezixhobo

Njengoko nokubunjwa kweenkqubo zoshishino wokwenziwa iimveliso ziyahluka iindlela kwintlangano zabo zobugcisa. Ukusetyenziswa koomatshini compact ingasetyenziswa kwi isithuba kumgangatho esincinane echaphazela imali iindleko zemveliso. Isiqhelo uhlenga lo gama kuqinisekiswa inkqubo yokuvelisa imveliso oqaphelekayo ingakumbi kwiindawo neemfuno zasekhaya. Ngenxa yoko, imveliso iingxowa ezinepolypropylene swi abaphulaphuli ebanzi kubathengi, Noko ke, phakathi kwazo nje kuphela abathengi abaqhelekileyo kodwa amashishini amakhulu. Oku kukhokelela ekubeni icandelo umdla ngakwicala kumashishini amancinci, kubalulekile ukuba ukuvula imigca zabo ngemveliso yazo.

Yintoni bag ezinepolypropylene?

Olu hlobo iingxowa ukupakisha, injongo leyo kuthathwa jikelele. Sekunjalo, le ndawo ingundoqo isicelo yeemveliso ezinjalo lancitshiswa ukusetyenziswa yasekhaya - njengendawo umthetho, ukuba kulawulwe izinto evakalala, ukuhlanganiswa ezomileyo, fillers zisitya, njl bag Polypropylene esetyenziselwa ukugcinwa kwezimpahla non-ukutya. Nditsho ishishini lokwakha yenza usebenziso olunzulu iphakheji enjalo ukugcina ezithutha isamente, amalahle, amaqabane ezahlukeneyo kunye nobutyobo.

Kuxhomekeka kuhlobo ubuchule lokuvelisa sifakwa ngoku, imveliso sinikezwe ezi okanye nezinye iimpawu. Umzekelo, imveliso iingxowa ezinepolypropylene eRashiya kutshanje ngamandla nokuphuhlisa ubuchwepheshe izicwili conductive. Ngenxa ezintsha asolwa zivuselela iingxowa conductive kunye antistatic. Ngokumalunga iimpawu ephambili nokukwazi ukumelana imithwalo, lo ezinepolypropylene umgangatho swi ubunzima 5.10 kg. Izingxobo ezizodwa enkulu nako ukumelana kg-50 okanye ngaphezulu, kodwa iimveliso ezinjalo jikelele enziwa ngokwemiyalelo ngamnye.

izigaba kwetheknoloji kwimveliso

Inkqubo iqala ulungiselelo lwe umbandela ekrwada isiseko yenziwa apho apha kwakhiwe iibhegi. Le plastiki lokuqala granules lokufaka mixed kwaye zonekwe. Ngenxa yezizathu kuqoqosho, kunye wavumela imveliso iingxowa ezinepolypropylene ukuze zirisayikilisheke, nto leyo enokuthi zixutywe nesiseko ecacileyo, emva koko umxube yathotyelwa kwimeko amabala kunye exutywe kunye nezongezelelo uguqulo kancincane.

Inqanaba elilandelayo kukuba ukondla ubunzima kwayiloo extruder apho lashushu 260 ° C. Isiphumo sale nyathelo inkqubo yokutshata nemisonto tyaba. Iindlela ukusika nobuchwepheshe okupholisa ivumela ubungakanani kangangoko ukwenza kwimicu ezimcaba ukuba iingxowa plexus elizayo.

Ukuyila isiseko laphu kuveliswe kwi zinto setyhula, ekuthi kwezo nto kuphume emkhonweni ngokubhijela Imicu ephothiweyo kwi emasondweni okhethekileyo. Inyathelo lokugqibela nangokukrola kwesiseko laphu ogqityiweyo banikwa imilinganiselo kunye nezinto nezitishi zibe ziimveliso ugqibile. Kubonakala ngathi imveliso ezaziwa iingxowa ezinepolypropylene. Technology kunye nezixhobo nazo ziquka ezinye iimpawu inkqubo, ngenxa iimfuno umthengi lowo. Ngokomzekelo, njengenyathelo ezongezelelweyo ingangeniswa flexography.

Extrusion Line nemisonto flat

Ukuveliswa ngqo izinto apho ingxowa wenziwe ezinepolypropylene, iqala inkqubo extrusion. Ukuqala ukuvunwa umxube ohambelana, nto leyo nayo ezingqanyaniswe umsebenzi ofunekayo imveliso yokugqibela. Isiseko ilayini extruder, nto leyo yenza yeplastiki umboniso. Imifanekiso ukusebenza uluhlu olubanzi Polymer-based, kodwa kunjalo imisebenzi eziphambili ziquka zokufudumeza, extrusion kunye zokuzoba. Ukuba imveliso okunqwenelwayo iingxowa ezinepolypropylene yobukhulu enkulu, le extruder eqale iqwalaselwe ukuba unikeze imicu ebanzi ashinyeneyo. Noko ke, inyathelo elilandelayo ikuvumela ukunyenyisa umboniso kwi fomathi olifunayo.

iSetyhula esisemnyango

Ukuze kwakhiwe isiseko ngelaphu kusetyenziswa iiyunithi Setyhula. Nendalo yawo kwenzeka nge sleeve oqhubekayo ezinepolypropylene. Kukho iinguqulelo ezininzi esi sixhobo, ezahluke inani shuttles. Ngenxa yoko, phakathi kwinguqulelo esisiseko Kungaba liphathwe umatshini 4-nesiphekepheke. Izinto eziluncedo lo matshini inika inani ubuncinane amalungu ngokuxhomekeke ukunxiba, iyenza outperforms analogue ngaphakathi kwalo. Kwakhona kwandisa ukuthembeka kunye nomgca ngokubanzi, apho imveliso iingxowa ezinepolypropylene.

Ezi zixhobo inikezelwa nenkqubo ukudluliselwa kunye amavili mqengqeleki, ongazifuniyo ukuthambisa ajikeleze rhoqo. Le kujonge izinto, bona, abangele nokuchulumacha yesondlo.

Machines iingxowa ukusika nezitishi

Cutting iya kwenziwa ngesandla kwaye zoomatshini. Yandile nokuveliswa industrial ngakumbi sebenzisa ukhetho lokuqala. Kulo mzekelo, iiyunithi ezisetyenziswayo ukwenza nangokukrola ezingxobo elungiselelwe ngesantya avareji enemikhono amaqhosha 40-50 ngokuzenzekelayo. Ububanzi iphezulu rolls, ziyafumaneka ukuze kungonakali, lufikelela 800 mm ekwiimo eqhelekileyo. Kwezinye iimeko, sigwetyelwe nokuveliswa manual lweengxowa ezinepolypropylene.

Olu hlobo itheknoloji kubandakanya ukusetyenziswa iitafile ezizodwa apho abasebenzisi-nkonzo, kuquka ubukhulu ezingekho semgangathweni kunye enemikhono. Emva koko, kwimeko engena izixhobo nokuthunga iziseko aqingqiweyo for ezingxoweni. lokubolekwa ezinjalo Ngokuqhelekileyo wambumba emqukumbelweni nomphezulu zikhabane somchako zeplastiki.

Machines flexo

Printing ukwenza oomatshini ezizodwa, anikeziweyo ngu menzi woluvo umfanekiso. Lo matshini zixhaphakileyo bhetyebhetye kwenza ushicilelo kwi izihlunu zeplastiki of polyethylene kunye ezinepolypropylene. Kwezinye imigca nazo kusetyenziswa imishini ukuba luphawulwa ubuchule babo ukuba babacingele emibini kunye nombala ezintathu-shicilelwayo. Lo matshini eliphezulu-ngqo mihla, apho ukulawula ilungiselelwa ngokusebenzisa panel elektroniki. Ngokukodwa, imveliso iingxowa ezinepolypropylene (umfanekiso eboniswe ngezantsi) lubandakanya ukusetyenziswa kwezixhobo flexographic yale hlobo.

Iimfuneko iimeko zemveliso

Kungakhathaliseki ukuba ubume intambo yokusebenza, ukuveliswa umnini kufuneka anike imiqathango efanelekileyo yokusebenza izixhobo. Kwindawo yokuqala, ngokunjalo zonke iivenkile, ukusebenza nto leyo ehambisana kunye nokuqwalaselwa Iipholima, imigca ezinjalo kufuneka zisuswe amakhaya. Kwizikhewu efanayo kakhulu ukubonelela ngenkqubo umoya esebenzayo ukwenza unxibelelwano ngokohlobo umjelo kunye namanzi neziphaluka, kwakunye ukuthatha unonophelo ukufakelwa okucoca zokucoca amanzi.

Ke ukuba ubungakanani gumbi, imveliso iingxowa ezinepolypropylene ngokuqhelekileyo luqhutywa kwimveliso imigca kwindawo angekho ngaphantsi kwe-50 m2. Ngako oko, ngenxa yokulungiswa ngokupheleleyo kwicandelo yokusebenza ubungakanani ezintsonkothileyo kufuneka ubuncinane 80 m2.

isiphelo

Inkqubo yokwenza iingxowa ezinepolypropylene kufuna utyalo-mali kakhulu entlanganweni. Irenti kweendawo kunye nokuthengwa kwezixhobo - kuphela izinto ezisisiseko yenkcitho, kodwa kwixesha elizayo kusenokuba yimfuneko kunye nokudalwa amanyathelo inkqubo eyongezelelweyo lweshishini.

Umzekelo, ukuveliswa lokhuphiswano iingxowa ezinepolypropylene kwiimeko mihla kunokwenzeka kuphela xa esweni ngononophelo umgangatho imveliso. Ngenxa yoko, ukuphuculwa kunye kumhlathi amazwe kuviwo kweemveliso. Kananjalo kuya kufuneka ukuba iimeko ukugcinwa kunye nentlangano impahla. Nangona iibhegi ezinepolypropylene musa ukuya eninzi isithuba kwaye musa ukuba iimeko ezizodwa yokugcina, inkangeleko yabo ziphangwe ngu neziphumo ngoomatshini ngexesha izithuthi - kwakhona akufuneki ukulibale oku.
