Okwangoku kukho iintlobo ezimbini ezinamachaphaza angenazimali ezingenamali zokupakisha eziguqukayo, izinto ezingatshatanga kunye nezabini. Inxalenye enye isetyenziselwa iphepha kwaye engafane isebenze ngaphandle kokuxuba kwaye ungahlengahlengisi umyinge. Izinto ezimbini zinokusetyenziselwa ifilimu eyahlukeneyo yefilimu. Ngokusekwe kumava obuqu, eli phepha liza kuchaza indlela yokutshintsha umlinganiselo wamacandelo amabini ngeenjongo ezahlukeneyo nendlela esebenza ngayo.
Okokuqala, umgaqo wokuxuba we-bimiot of School-wakhululeka.
Zintathu iinkalo ezikwi-ratio yoyilo lwe-sconvent-free ingenayo
1. Zama ukutshatisa umyinge ongumxube wezinto ze-A & B kubunzima.
I-A / B 'I-Compaction yokuBhala i-A / B Umzekelo, x yi-100A ixutywe ne-90b, y yi-100a ne-50b. I-1% yokutshintsha kwe-B iyakukhokelela kwi-1.1% yokutshintsha kwesisindo ye-X kunye ne-2% ye-Y. Ngokubanzi, i-2% yokutshintsha komlinganiso wemveliso yamkelekile ngexesha le-2. 2 % kwaye i-4%. Ukuba ubunzima babo bahluka kakhulu, oku kunokukhokelela kwezi-anolies zilandelayo:
.
.
2. Kufutshane kangangoko kunokwenzeka kuhlobo lwezinto ze-A & B
I-viscofity ye-viscosity yecandelo A & B kwiqondo lobushushu elifanelekileyo, kungcono umxube wokuxuba. Ukujonga isenzo se-binder, uVenkile wokuqala wawo omabini la mahluko wahluke ngokupheleleyo. Iqondo lokushisa kufuneka lilawulwe ngokwahlukeneyo ukulungisa ixabiso le-viscous. Ukonyusa ubushushu benxalenye yokuqala ngophawu oluphezulu lwenza ukuba kufuphi nelinye icandelo, kwaye luyingenelo kuwo omabini isixhobo somxube kunye nempompo yemveliso.
3. Ukonyusa ukunyamezelana komxube we-A & B
Ngenxa yezinye izinto zangaphandle ngokunakalisa, kufuneka kubekho ukuphambuka kumlinganiso wokudibanisa. Ukwandisa ukunyamezelana komgangatho wokudityaniswa komgangatho we-A / B ukudibanisa ngokufanelekileyo kunokubuyisela ngokufanelekileyo isiphumo salo mbandela. Umzekelo, i-Songavent yeSolvent yasimahla ye-WD8118A / B yezinto ezintsha ezivela kwi-100: 75 ukuya kumxube we-100: 60 - 85, zombini zamkelekile ukuba zisetyenziswe ngabathengi abaninzi.
Okwesibini, umgaqo kunye nendlela yokuxuba uhlengahlengiso lwe-ratio
(1) Uhlengahlengiso lweqondo lobushushu kunye nomswakama
Ngokubanzi, umxholo we-NCO kwicandelo a aphezulu, ngelixa impendulo enomoya kunye ne-vapor kwifilimu isekhohlo. Nangona kunjalo, ngeenyanga zasehlotyeni, xa kukho i-steam engakumbi emoyeni kwaye ifilimu inomxholo ophezulu wokufuma, icandelo elinokukhulisa ukuchitha i-Steam, eya kuqhuba impendulo efanelekileyo yokuthambelela.
(2) uhlengahlengiso lwezinto ze-inki kunye nentsalela ye-solvent
Uninzi lokupakisha ifilimu iprintiweyo, inkqubo yokuprinta yasekhaya inesimo se-inki ye-Solvent. Kwii-Inki ezisekwe kwi-Solvent njengesongezo ziya kubakho kwaye ziya kufika kwakhona, zombini yinkqubo ye-Polyurethane, kwi-obedherthane ressin, kwi-adhenges kunye ne-NCO impendulo inokutya i-NCO.
Sixhalabele ubunyulu kunye nokufuma komswakama kwesolokisiwe. Baza kuhlala ngaphezulu okanye ngaphantsi kushicilelo, kwaye i-hydrogen esebenzayo isebenza i-NCO. Ukuba intsalela kunye nentsalela yokubuyela umva iphezulu, songeza icandelo a ukuphucula iziphumo.
(3) Uhlengahlengiso lwe-aluminium yokudluliselwa
Izinto ezininzi zokupakisha eziguquguqukayo ngoku zikhethwe, kwaye isiphumo soxinzelelo sinokuncitshiswa ngokuhlengahlengiswa komyinge we-AF / B ukunciphisa ngokufanelekileyo i-aluminium ngokusebenzisa amachaphaza amachaphaza .
