Iindaba

Kwimveliso yeefilimu zeplastiki, iifilimu ezifakwe i-PE (Polyethylene) zidlala indima ebalulekileyo kwizicelo ezininzi zokupakisha. Nangona kunjalo, inkqubo yokuvelisa iifilimu ze-PE ezisemgangathweni ophezulu iza nemingeni yayo, kwaye kulapho ii-arhente zokutyibilika kunye nezokulwa nokuvalwa zingena khona.

Imfuneko yokusebenzisaiiarhente zokutyibilika kunye nezokuthintela ukuvimbaKwinkqubo yefilimu eqhushumbiswe yi-PE ayinakugqithiswa. Njengoko iifilimu ze-PE ziveliswa, zinesimo sendalo sokunamathelana ngenxa yendalo yazo egudileyo neguquguqukayo. Le nto, eyaziwa ngokuba kukuvimba, inokubangela iingxaki ezibalulekileyo ngexesha lokusonga ifilimu, ukugcinwa kwayo, kunye nokusetyenziswa kwayo okulandelayo. Ngaphandle kokongezwa kwee-anti-block agents, iifilimu ziya kuhlangana, okwenza kube nzima ukuzikhulula kakuhle okanye ukuzisebenzisa ngeenjongo zokupakisha. Ukongeza, ukungqubana komphezulu kweefilimu kunokuba phezulu, nto leyo enokubangela ubunzima kwimisebenzi yokupakisha ekhawulezayo. Apha,iiarhente zokutyibilikazize zincede. Zinciphisa ukungalingani kokungqubana kumphezulu wefilimu, zivumela ukuphathwa okuthambileyo kunye nokulungiswa ngokukhawuleza. Umzekelo, ekupakishweni kweemveliso zokutya ezifana nezidlo ezincinci okanye iimpahla ezikhenkcezisiweyo, iifilimu kufuneka zityibilike lula phezu koomatshini bokupakisha ukuqinisekisa ukuba imigca yemveliso isebenza kakuhle.

Xa kufikwa kwiintlobo zeiiarhente zokutyibilikaKukho uluhlu olwahlukeneyo. Udidi olunye oluqhelekileyo yi-fatty acid amides. Ezi zisetyenziswa kakhulu ngenxa yokusebenza kwazo ekunciphiseni ukungqubana. Zisebenza ngokufudukela kumphezulu wefilimu kwaye zenze umaleko wokuthambisa. Olunye uhlobo zii-silicone-based slip agents, ezibonelela ngeempawu ezintle zokutyibilika kwaye zifanelekile ngakumbi kwizicelo apho kufuneka i-coefficient ephantsi kakhulu yokungqubana, njengakwimveliso yokupakisha izixhobo zonyango. Kukwakho nee-wax-based slip agents ezibonelela ngesisombululo esingabizi kakhulu kwezinye izicelo zokupakisha ezisetyenziswa ngokubanzi.

Nangona kunjalo, ngelixa i-amide-basediiarhente zokutyibilikaZithandwa kakhulu, zibangela ingxaki enokubakho – ingxaki yokuqhakaza okanye ukufuduka. Xa kusetyenziswa izixa ezikhulu zee-amide slip agents, ekuhambeni kwexesha, zinokufudukela kumphezulu wefilimu zize zikhanye. Esi siphumo sokuqhakaza sinokukhokelela ekubonakaleni okumnyama okanye okunamafu kwifilimu, into engathandekiyo, ingakumbi kwizicelo apho ukucaca kubalulekile, njengakwiphakheji yeemveliso ezicacileyo ezifana nezinto zokuthambisa okanye ezinye izinto zokutya eziphambili. Ngaphezu koko, i-amide efudusiweyo inokuchaphazela ukuprintwa kwefilimu. Ingaphazamisa ukunamathela kwe-inki, nto leyo ekhokelela kumgangatho ophantsi wokuprinta, ukuguguleka, okanye ukukrazuka kwe-inki. Oku kunokuba yingxaki enkulu kwiimpawu ezixhomekeke kwiiprinti zokupakisha ezikhanyayo nezicacileyo ukutsala abathengi.

SILIKE iarhente yokutyibilika engaqhakaziyo, phucula umgangatho wokupakisha okuguquguqukayo okanye ezinye iimveliso zefilimu

Ukuze kusonjululwe le ngxaki, iqela lophando nophuhliso lwe-SILIKE liphumelele ekuphuhliseni i-arhente yokuthambisa ifilimu eneempawu zokungavuthi kwamanzi ngokuzama nokuphucula. I-SILIKE super slip kunye ne-anti-blocking masterbatch yimveliso ephandwe ngokukodwa kwaye yenzelwe iifilimu zeplastiki. Le mveliso iqulethe i-polymer ye-silicone eguqulwe ngokukodwa njengesithako esisebenzayo sokuphelisa iingxaki eziqhelekileyo ezinazo ii-agents zokuthambisa zemveli, ezinje ngemvula kunye nokunamathela kobushushu obuphezulu, njl.

SILIKE iarhente yokutyibilika engaqhakaziyoyimveliso ye-co-polysiloxane eguquliweyo equlethe amaqela asebenzayo e-organic, kwaye iimolekyuli zayo ziqulathe zombini iinxalenye ze-polysiloxane chain kunye namaqela asebenzayo e-long carbon chain. Ekulungiseleleni ifilimu yeplastiki, ineempawu ezibalaseleyo zobushushu obuphezulu obuthambileyo, inkungu ephantsi, akukho mvula, akukho mgubo, akukho mpembelelo ekutywineni kobushushu, akukho mpembelelo ekuprinteni, akukho vumba, i-stability friction coefficient njalo njalo. Le mveliso isetyenziswa kakhulu ekuveliseni iifilimu ze-BOPP/CPP/PE/TPU/EVA, ezifanelekileyo kwiinkqubo zokubumba, ukubumba ngebhombu kunye nokuzoba.

Ukuqukumbela, ukuqonda ukusetyenziswa ngokufanelekileyo kweiiarhente zokutyibilika kunye nezokuthintela ukuvimbaekucutshungulweni kwefilimu ephuhliswe yi-PE kubalulekile kubavelisi. Ngokukhetha ngononophelo uhlobo olufanelekileyo kunye nobungakanani bezi zongezo, banokoyisa imingeni yokuthintela ifilimu kunye nokungqubana okuphezulu, ngelixa bekwanciphisa imiba enokubakho yomgangatho enxulumene neearhente ezithile.

Ukuba ufuna ukuphucula umgangatho wokupakisha okuguquguqukayo okanye ezinye iimveliso zefilimu, ungacinga ngokutshintsha iarhente yokuthambisa, ukuba ufuna ukuzama iarhente yokuthambisa ifilimu ngaphandle kokuyinika amanzi, ungaqhagamshelana ne-SILIEK, sinezisombululo ezahlukeneyo zokulungisa ifilimu yeplastiki.
