Amanqaku olawulo lweNkqubo ye-Solvent-Free Compound

Inkcazo: Eli nqaku ikakhulu lizisa amanqaku olawulo lwenkqubo ye-solvent-free composite, kubandakanywa, ulawulo lobushushu, ukulawula umthamo, ukulawula uxinzelelo, ulawulo loxinzelelo, i-inki kunye neglue, ukulawula ukufuma kunye nokusingqongileyo, ukutshisa iglue, njl.

I-solvent free composites iya isetyenziswa kakhulu, kwaye indlela yokusebenzisa kakuhle le nkqubo sisihloko esixhalabisayo wonke umntu.Ukusebenzisa kakuhle i-solvent-free composites, umbhali ucebisa ngamandla ukuba amashishini anemiqathango asebenzise izixhobo ezininzi ezingenayo i-solvent okanye iisilinda zeglue ezimbini, oko kukuthi, sebenzisa iisilinda zeglue ezimbini, enye iqulethe i-adhesive jikelele egubungela uninzi lwesakhiwo semveliso, kwaye enye ikhetha i-adhesive esebenzayo efanelekileyo kumphezulu okanye umaleko wangaphakathi njengesongezelelo esisekelwe kwisakhiwo semveliso yomthengi.

Izibonelelo zokusebenzisa i-cylinder yerabha ephindwe kabini yile: inokunyusa uluhlu lwesicelo se-solvent-free composites, ukunciphisa ukukhutshwa, ukuba neendleko eziphantsi, kunye nokusebenza okuphezulu.Kwaye akukho mfuneko yokucoca rhoqo i-cylinder yeglue, ukutshintsha i-adhesives, kunye nokunciphisa inkunkuma.Unokukhetha kwakhona i-adhesives ngokusekelwe kwimveliso kunye neemfuno zabathengi ukuqinisekisa umgangatho wemveliso.

Kwinkqubo yenkonzo yabathengi bexesha elide, ndiphinde ndishwankathele amanqaku athile olawulo lwenkqubo ekufuneka ahlawulelwe ingqalelo ukuze enze umsebenzi olungileyo kwicomposite engena-solvent.

1.Coca

Ukufezekisa i-composite elungileyo engena-solvent, into yokuqala ekufuneka uyenzile kukucoceka, nto leyo ekwayingongoma ejongelwa phantsi lula ngamashishini.

I-roller eqinileyo esisigxina, ukulinganisa i-roller eqinile, i-coating roller, i-coating pressure roller, i-composite roller eqinile, i-tube yesikhokelo sokuxuba, umgqomo we-agent oyintloko kunye nokunyanga umatshini wokuxuba, kunye ne-roller ezahlukeneyo zesikhokelo, kufuneka zihlambuluke kwaye zingabikho kwizinto zangaphandle, kuba nayiphi na into yangaphandle kwezi ndawo iya kubangela amaqamza namabala amhlophe kumphezulu wefilimu edibeneyo.

2.Ulawulo lobushushu

Isithako esiphambili se-adhesive-free adhesive yi-NCO, ngelixa i-arhente yokunyanga i-OH.Ubuninzi, i-viscosity, ukusebenza kwezinto eziphambili kunye nokunyanga, kunye nezinto ezifana nobomi benkonzo, ubushushu, ubushushu bokunyanga, kunye nexesha le-adhesive, zonke zinokuchaphazela umgangatho we-composite.

I-adhesive ye-solvent yamahhala ye-polyurethane ine-viscosity ephezulu kwiqondo lokushisa kwegumbi ngenxa yokungabikho kweeamolekyu ezincinci ze-solvent, amandla aphezulu e-intermolecular, kunye nokwakhiwa kweebhondi ze-hydrogen.Ukufudumeza kunokunciphisa ngokufanelekileyo i-viscosity, kodwa ubushushu obuphezulu obugqithisileyo bunokukhokelela ngokulula kwi-gelation, ukuvelisa ii-resin ezinobunzima be-molecular, okwenza ukuba kube nzima okanye ukungalingani.Ngoko ke, ukulawula ukushisa kwengubo kubaluleke kakhulu.

Ngokubanzi, ababoneleli abancamathelayo baya kubonelela abathengi ngeeparamitha ezithile zokusetyenziswa njengereferensi, kwaye ubushushu bokusetyenziswa bunikwa ngokubanzi njengexabiso loluhlu.

Ukuphakama kweqondo lokushisa ngaphambi kokuxuba, i-viscosity ephantsi;ukuphakama kweqondo lokushisa emva kokuxuba, ukuphakama kwe-viscosity.

Ukulungiswa kweqondo lokushisa kwe-roller yokulinganisa kunye ne-coating roller ikakhulu kuxhomekeke kwi-viscosity ye-adhesive.Ukuphakama kwe-viscosity ye-adhesive, iphakamileyo yokushisa kwe-roller yokulinganisa.Ubushushu berola edibeneyo bunokulawulwa ngokubanzi malunga ne-50 ± 5 ° C.

3.Ulawulo lwemali yeglue

Ngokwezinto ezidityanisiweyo ezahlukeneyo, iimali ezahlukeneyo zeglue zingasetyenziswa.Njengoko kuboniswe kwitheyibhile, uluhlu olusondeleyo lwexabiso leglue linikezelwa, kwaye ukulawulwa kwesixa seglue ekuveliseni ngokukodwa kunqunywe ngumlinganiselo we-gap kunye nesantya phakathi kwe-roller yokulinganisa kunye ne-roller esisigxina.Isixa sesicelo seglue

4.ulawulo loxinzelelo

Ngenxa yokuba i-coating roller ilawula ubungakanani beglue esetyenziswe yi-gap kunye nesantya somlinganiselo phakathi kwee-roller ezimbini zokukhanya, ubungakanani boxinzelelo lwe-coating buya kuchaphazela ngokuthe ngqo inani leglue elisetyenzisiweyo.Ukuphakama koxinzelelo, kuncinci inani leglue elisetyenzisiweyo.

5.Ukuhambelana kwe-inki kunye neglu

Ukuhambelana phakathi kwe-adhesives-free adhesives kunye nee-inki kulungile namhlanje.Nangona kunjalo, xa iinkampani zitshintsha abenzi be-inki okanye iinkqubo zokuncamathelisa, kusafuneka zenze uvavanyo lokuhambelana.

6.Ulawulo loxinzelelo

Ulawulo loxinzelelo lubaluleke kakhulu kwicomposite enganyibilikiyo kuba ukuncamathela kwayo kokuqala kuphantsi kakhulu.Ukuba ukunyanzeliswa kweembrane zangaphambili nangemuva azihambelani, kukho ithuba lokuba ngexesha lenkqubo yokuvuthwa, i-shrinkage ye-membrane ingaba yinto eyahlukileyo, okubangelwa ukubonakala kwamabhubhu kunye nemigudu.

Ngokuqhelekileyo, ukondla kwesibini kufuneka kuncitshiswe kangangoko kunokwenzeka, kwaye kwiifilimu ezityebileyo, uxinzelelo kunye nobushushu be-roller edibeneyo kufuneka kwandiswe ngokufanelekileyo.Zama ukuphepha ukugoba ifilimu edibeneyo kangangoko kunokwenzeka.

7.Lawula ukufuma kunye nokusingqongileyo

Ukujonga rhoqo utshintsho kumswakama kwaye ulungelelanise umlinganiselo we-arhente ephambili kunye ne-arhente yokunyanga ngokufanelekileyo.Ngenxa yesantya esikhawulezayo se-solvent-free composite, ukuba ukufuma kuphezulu kakhulu, ifilimu edibeneyo ehlanganiswe ngeglu iya kuhlala idibana nokufuma emoyeni, isitya i-NCO, okukhokelela kwizinto ezifana neglue engomisi kwaye ihlwempuzekile. ukuxobula.

Ngenxa yesantya esiphezulu somatshini wokulahla i-solvent-free, i-substrate esetyenzisiweyo iya kuvelisa umbane osisigxina, obangela ukuba ifilimu yokushicilela ithathe kalula uthuli kunye nokungcola, okuchaphazela ukubonakala komgangatho wemveliso.Ngoko ke, indawo yokusebenza yemveliso kufuneka ivalwe ngokulinganayo, igcine iworkshop phakathi komgangatho wobushushu obufunekayo kunye nokufuma.

8.Glue ukufudumeza

Ngokuqhelekileyo, iglue ngaphambi kokungena kwi-cylinder kufuneka ifakwe ngaphambili, kwaye iglue edibeneyo ingasetyenziselwa kuphela emva kokufudumeza kwiqondo lokushisa elithile ukuze kuqinisekiswe izinga lokudluliselwa kweglue.

9.Isiphelo

Kwinqanaba langoku apho i-solvent-free composite kunye ne-composite eyomileyo idibene, amashishini kufuneka akhulise ukusetyenziswa kwezixhobo kunye nenzuzo.Inkqubo ingaba yi-solvent-free composite, kwaye ayiyi kuba yinto eyomileyo.Ukulungiselela imveliso ngokufanelekileyo nangokufanelekileyo, kunye nokusebenzisa ngokufanelekileyo izixhobo ezikhoyo.Ngokulawula inkqubo kunye nokuseka iincwadana zokusebenza ezichanekileyo, ilahleko yemveliso engeyomfuneko ingancitshiswa.
