Isishwankathelo: Eli nqaku lizazisa ikakhulu iindawo zolawulo lwenkqubo ye-composite engenasombululo, kubandakanya, ulawulo lobushushu, ulawulo lobungakanani be-coating, ulawulo loxinzelelo, ulawulo loxinzelelo, ukudibanisa i-inki kunye neglue, ukulawula ukufuma kunye nokusingqongileyo, ukufudumeza kwangaphambili kweglue, njl.
Ii-composites ezingena-solvent ziyanda ukusetyenziswa, kwaye indlela yokusebenzisa kakuhle le nkqubo yingongoma exhalabisa wonke umntu. Ukuze zisetyenziswe kakuhle ii-composites ezingena-solvent, umbhali ucebisa kakhulu ukuba amashishini aneemeko asebenzise izixhobo ezininzi ezingena-solvent okanye ii-double glue cylinders, oko kukuthi, asebenzise ii-glue cylinders ezimbini, enye equlethe i-universal adhesive egubungela uninzi lwesakhiwo semveliso, kwaye enye ikhethe i-adhesive esebenzayo efanelekileyo kumphezulu okanye kumaleko wangaphakathi njengesongezelelo ngokusekelwe kwisakhiwo semveliso yomthengi.
Iingenelo zokusebenzisa isilinda yerabha ephindwe kabini zezi: inokunyusa uluhlu lwezinto ezidityanisiweyo ezingenasombululo, inciphise ukukhutshwa komoya, ibe neendleko eziphantsi, kwaye isebenze kakuhle. Kwaye akukho mfuneko yokucoca isilinda yeglue rhoqo, ukutshintsha izincamathelisi, kunye nokunciphisa inkunkuma. Ungakhetha nezincamathelisi ngokusekelwe kwiimfuno zemveliso kunye nabathengi ukuqinisekisa umgangatho wemveliso.
Kwinkqubo yenkonzo yabathengi yexesha elide, ndikwashwankathele amanqaku athile olawulo lweenkqubo ekufuneka anikwe ingqalelo ukuze kwenziwe umsebenzi olungileyo kwi-composite engenasombululo.
1. Ucoceko
Ukuze ufumane i-composite elungileyo engenasombululo, into yokuqala ekufuneka yenziwe kukucoceka, nto leyo ekwayinto engananzwa lula ngamashishini.
Irola eqinileyo esisigxina, irola eqinileyo yokulinganisa, irola yokugquma, irola yoxinzelelo lokugquma, irola eqinileyo edibeneyo, ityhubhu yesikhokelo sokuxuba, ibhereli ephambili kunye neyokuphilisa yomatshini wokuxuba, kunye neerola ezahlukeneyo zesikhokelo, kufuneka zicoceke kwaye zingabi nazinto zangaphandle, kuba nayiphi na into yangaphandle kwezi ndawo iya kubangela amaqamza kunye namabala amhlophe kumphezulu wefilimu edibeneyo.
2. Ulawulo lobushushu
Isithako esiphambili seglue engenasombululo yi-NCO, ngelixa i-agent ephilisayo yi-OH. Ubuninzi, ukuxinana, ukusebenza kwee-agent eziphambili kunye ne-curing, kunye nezinto ezifana nobomi benkonzo, ubushushu, ubushushu bokupholisa, kunye nexesha leglue, zonke ezi zinto zinokuchaphazela umgangatho weglue edibeneyo.
I-adhesive ye-polyurethane engenaso isinyibilikisi ine-viscosity ephezulu kubushushu begumbi ngenxa yokungabikho kwee-molecules ezincinci zesinyibilikisi, amandla aphezulu e-intermolecular, kunye nokwakheka kweebhondi ze-hydrogen. Ukufudumeza kunokunciphisa ngempumelelo i-viscosity, kodwa amaqondo obushushu aphezulu kakhulu anokukhokelela kwi-gelation, avelise ii-resin ezinobunzima obukhulu be-molecular, okwenza i-coating ibe nzima okanye ingalingani. Ke ngoko, ukulawula amaqondo obushushu e-coating kubaluleke kakhulu.
Ngokubanzi, ababoneleli ngeglu baya kubonelela abathengi ngemida ethile yokusetyenziswa njengesalathiso, kwaye ubushushu bokusetyenziswa bunikwa njengexabiso loluhlu.
Okukhona ubushushu buphezulu ngaphambi kokuxuba, kokukhona ubushushu buphantsi; kokukhona ubushushu buphezulu emva kokuxuba, kokukhona ubushushu buphezulu.
Uhlengahlengiso lobushushu lwerola yokulinganisa kunye nerola yokugquma luxhomekeke kakhulu kwi-viscosity ye-glue. Okukhona i-viscosity ye-glue iphezulu, kokukhona i-viscosity ye-roll yokulinganisa iphezulu. Ubushushu be-roll edibeneyo ngokubanzi bunokulawulwa malunga ne-50 ± 5 ° C.
3. Ulawulo lobungakanani beglue
Ngokwezinto ezahlukeneyo ezidityanisiweyo, ubungakanani obahlukeneyo beglu bungasetyenziswa. Njengoko kubonisiwe kwitheyibhile, uluhlu oluqikelelweyo lobungakanani beglu lunikiwe, kwaye ulawulo lobungakanani beglu ekuvelisweni lumiselwa ikakhulu ngumsantsa kunye nomlinganiselo wesantya phakathi kwerola yokulinganisa kunye nerola esisigxina.Isixa sesicelo seglue
4.ulawulo loxinzelelo
Ngenxa yokuba i-coating roller ilawula ubungakanani beglu esetyenziswa ngumsantsa kunye nomlinganiselo wesantya phakathi kwee-light rollers ezimbini, ubungakanani boxinzelelo lweglue buya kuchaphazela ngokuthe ngqo ubungakanani beglue esetyenziswayo. Okukhona uxinzelelo luphezulu, kokukhona inani leglue esetyenziswayo lincinci.
5. Ukuhambelana phakathi kwe-inki kunye neglu
Ukuhambelana phakathi kwezincamathelisi kunye nee-inki ezingenasombululo ngokubanzi kulungile kule mihla. Nangona kunjalo, xa iinkampani zitshintsha abavelisi be-inki okanye iinkqubo zokuncamathelisa, kusafuneka zenze uvavanyo lokuhambelana.
6. Ulawulo loxinzelelo
Ulawulo loxinzelelo lubaluleke kakhulu kwi-composite engenasombululo kuba ukunamathela kwayo kokuqala kuphantsi kakhulu. Ukuba uxinzelelo lwee-membrane zangaphambili nangasemva aluhambelani, kunokwenzeka ukuba ngexesha lenkqubo yokuvuthwa, ukuncitshiswa kwee-membrane kunokwahluka, okubangela ukubonakala kwamaqamza kunye nemijelo.
Ngokubanzi, ukondla kwesibini kufuneka kuncitshiswe kangangoko kunokwenzeka, kwaye kwiifilimu ezityebileyo, uxinzelelo kunye nobushushu berola edibeneyo kufuneka kunyuswe ngokufanelekileyo. Zama ukuphepha ukugoba kwefilimu edibeneyo kangangoko kunokwenzeka.
7. Lawula ukufuma kunye nokusingqongileyo
Jonga rhoqo utshintsho kumswakama kwaye ulungise umlinganiselo we-arhente ephambili kunye ne-arhente yokupholisa ngokufanelekileyo. Ngenxa yesantya esikhawulezayo se-composite engenasombululo, ukuba umswakama uphezulu kakhulu, ifilimu edibeneyo egqunywe ngeglu iya kuhlala idibana nomswakama osemoyeni, idle i-NCO ethile, nto leyo ekhokelela kwiziganeko ezifana neglu engomiyo kunye nokuxobuka kakubi.
Ngenxa yesantya esiphezulu somatshini wokulaminetha ongenaso isinyibilikisi, isiseko esisetyenzisiweyo siya kuvelisa umbane ongashukumiyo, nto leyo ebangela ukuba ifilimu yokuprinta ifunxe uthuli kunye nokungcola ngokulula, nto leyo echaphazela umgangatho wemveliso. Ke ngoko, imeko yokusebenza kwemveliso kufuneka ivalwe, igcine indawo yokusebenzela ikwiqondo lobushushu kunye nokufuma okufunekayo.
8. Ukufudumeza kwangaphambili ngeglu
Ngokubanzi, iglu ngaphambi kokungena kwisilinda kufuneka itshiswe kwangaphambili, kwaye iglu exutyiweyo inokusetyenziswa kuphela emva kokuba ifudunyezwe kubushushu obuthile ukuqinisekisa izinga lokudluliselwa kweglu.
9. Isiphelo
Kwinqanaba langoku apho i-composite engenasombululo kunye ne-composite eyomileyo zisebenza kunye, amashishini kufuneka asebenzise izixhobo kakuhle kwaye azuze. Le nkqubo inokuba yi-composite engenasombululo, kwaye ayisoze ibe yi-composite eyomileyo. Lungiselela imveliso ngokufanelekileyo nangokufanelekileyo, kwaye usebenzise izixhobo ezikhoyo ngokufanelekileyo. Ngokulawula inkqubo kunye nokumisela iincwadi zokusebenza ezichanekileyo, ilahleko zemveliso ezingeyomfuneko zinokuncitshiswa.
