Eli phepha ligxile kwi-double components solvent-free laminating adhesives, lixoxa ngepropathi yokulinganisa iimveliso ezingena-solvent.
1. Intsingiselo esisiseko yokulinganisa iPropati
Ipropathi yokulinganisa kukukwazi kweengubo ukulinganisa ngokulinganayo nangokuthe tye phezu komphezulu wezinto ezingaphantsi komhlaba.
2. Ubudlelwane kunye neziphumo zokulinganisa kwinqanaba kwizigaba ezahlukeneyo
Kwingxoxo elandelayo, izinto zokwenziwa aziguquki, kuquka ubunzima bokugquma, ubushushu, uxinzelelo, njl. Ngenxa yokuba zonke izinto ziya kubangela utshintsho kwiilaminate zokugqibela, siza kubona ezi zinto ziguqukileyo njengezizinzileyo.
Ngenxa yokuba i-adhesive engenaso isinyibilikisi ayinaso isinyibilikisi sokuba sisiseko, ipropati yokulinganisa ukusebenza kwe-adhesive ngokwayo. Xa sithetha, iya kuba nyulu ngakumbi, kodwa i-adhesive engenaso isinyibilikisi iseneempawu zayo.
Okokuqala, ipropati yokulinganisa ye-SF adhesive inolwalamano olusondeleyo ne-viscosity ye-adhesive ngokwayo. Ngelixa i-viscosity inolwalamano oluthe ngqo nobushushu kwaye iyahluka ngendlela eyahlukileyo, oko kuthetha ukuba i-viscosity ye-SF adhesive iya kuncipha xa ubushushu bunyuka. Emva koko phantsi kobushushu begumbi, i-viscosities ye-SF adhesives eluhlaza inomahluko omkhulu ngokweemodeli ezahlukeneyo ze-SF adhesive kunye neempawu zomzimba. Nangona kunjalo, phantsi kobushushu obufanelekileyo bokusebenza kwemodeli enye ye-SF adhesive, umahluko woluhlu lwe-viscosity yayo awubonakali kakuhle. Ke ngoko, imveliso ye-viscosity ephantsi mhlawumbi ayingcono xa uthelekisa imodeli enye ye-SF adhesive ephezulu kunye ne-viscosity ephantsi. Umzekelo, i-WD8262A/B ye-KANGDA NEW MATERIALS, phantsi kobushushu bayo bokusebenza (malunga ne-45℃), i-viscosity yayo yi-1100 mpa.s. Kodwa xa i-laminate ye-PET.INK/ALU, inokufikelela kwimbonakalo entle ngaphandle kwamachaphaza ngexesha le-lamination yokuqala. Njengesiphelo, akuthethi ukuba i-viscosity ephantsi inokuzisa imbonakalo entle. Utshintsho olunamandla lwe-SF adhesives lixesha elikhawulezayo, elifuna izinto ezininzi ukufikelela kwisiphumo esihle. Okwangoku, i-viscosity inomgangatho ophantsi. Umzekelo, phantsi kwama-80-90℃ (i-Double component SF adhesive), i-viscosity ayinatshintsho ingako xa ubushushu bunyuka.
Ukulinganisa kwe-Frist kukuqhubeka ngokwasemzimbeni kwesimo se-adhesive exutyiweyo. Emva kwenkqubo yokugquma, ipropati yayo yokulinganisa iyancipha ngakumbi kunye nokusabela ngokukhawuleza phakathi kwezinto ze-A&B kunye nokwehla kobushushu. Ngokubanzi, ukulinganisa kokuqala kwe-adhesive ye-SF kuthathwa njengokulinganisa emva kokujija kwe-lamination. Ngeli xesha i-viscosity ye-adhesive iya kuba nkulu kune-adhesive exutyiweyo kwiirola zokulinganisa.
Ukulinganisa i-adhesive eluhlaza kuthetha i-adhesive esemgangathweni kwiidrums ngaphambi kokuba ixutywe. Le propati yokulinganisa ayithathi nxaxheba kwinkqubo yokulamina iifilimu okanye iifoyile.
Ipropati yesibini yokulinganisa kukuba, emva kwenkqubo yokulaminatha nakwinqanaba lokunyanga, i-SF adhesive ingena kwinqanaba lokusabela ngokukhawuleza kwe-cross-link phantsi kwempembelelo yobushushu, kwaye ukusebenza kokulinganisa kwehla kuye kuphele ngokupheleleyo.
3. Isiphelo
Ipropati yokulinganisa i-adhesive ye-SF eluhlaza ngaphambi kokuba ixutywe > ipropati yokulinganisa yesibini > ipropati yokulinganisa i-adhesive ye-SF exutyiweyo kwiirola zokulinganisa > ipropati yokulinganisa yokuqala. Ke ngoko, indlela yokutshintsha kwe-viscosity ye-adhesives ye-SF ngokwenene yinkqubo ekhulayo, eyahlukileyo ngokucacileyo kwi-adhesives ze-SB.
Ukuba unemibuzo malunga ne-SF laminating yokupakisha okuguquguqukayo, sizimisele ukukunceda.
