Iiplastiki ezikhazimlayo eziphezulu (optical) zivame ukubhekisela kwizinto zeplastiki ezineempawu ezintle kakhulu, kunye nezinto eziqhelekileyo ziquka i-polymethylmethacrylate (PMMA), i-polycarbonate (i-PC), kunye ne-polystyrene (PS). Ezi zixhobo zinokuba nokungafihli okugqwesileyo, ukumelana nokukrweleka, kunye nokufana kwamehlo emva konyango olukhethekileyo.
Iiplastiki ezikhazimlayo eziphakamileyo zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ze-optical fields, ezifana ne-eyeglass lens, iilensi zekhamera, i-car lampshades, izikrini zeefowuni eziphathwayo, iipaneli zokujonga, njalo njalo. Ngenxa yobuhle bayo obugqwesileyo kunye neempawu ze-optical, iiplastiki ezicwebezelayo eziphezulu ziyakwazi ukuhambisa ukukhanya ngokufanelekileyo kwaye zibonelele ngokubonakalayo okucacileyo, ngelixa zikhusela izixhobo zangaphakathi kwimeko yangaphandle. Ngokubanzi, iiplastiki ezikhazimlisiweyo eziphezulu zinoluhlu olubanzi lwezicelo ekwenziweni kwezixhobo zamehlo, amaqokobhe emveliso ye-elektroniki, izinto zokwakha, kunye neminye imimandla, kwaye indima yabo ikakhulu kukubonelela ngokusebenza kakuhle kwamehlo kunye nokhuseleko, kodwa kunye nokuhombisa inkangeleko yokukhanya. imveliso.
Eminye yemiceli mngeni kunye neengxaki ezinokuthi kuhlangatyezwane nazo ngexesha lokusetyenzwa kweeplastiki ezicwebezelayo (optical) zibandakanya oku kulandelayo:
Utshintsho lweThermal:Ezinye iiplastiki ezikhazimlayo eziphezulu zixhomekeke kwi-thermal deformation ngexesha lenkqubo yokufudumeza, okukhokelela ekugqweniseni ubungakanani bemveliso egqityiweyo okanye imilo. Ngoko ke, kuyimfuneko ukulawula ukushisa kunye nexesha lokufudumeza ngexesha lokucubungula kwaye uthathe iindlela ezifanelekileyo zokupholisa ukunciphisa umphumo we-thermal deformation.
Amaqamza kunye namaqamza:Izinto zeplastiki ezikhazimlisiweyo eziphakamileyo zigqabhuka ngakumbi kwaye zithandeka kwi-burrs kunye namaqamza. Oku kunokuchaphazela ukungafihli kunye neempawu ezibonakalayo. Ukusombulula le ngxaki, iiparamitha ezifanelekileyo zokubumba iiparitha, ezinjengokwehlisa isantya sokutofa kunye nokwandisa ubushushu bokubumba, zingasetyenziselwa ukunciphisa ukuveliswa kwee-burrs kunye namaqamza omoya.
Umkrwelo womphezulu:Imigangatho yeplastiki ecwebezelayo ephezulu iyakwazi ukukhuhla, okuya kuchaphazela umphumo wabo we-optical kunye nomgangatho wokubonakala. Ukuze ugweme imikrwelo yomhlaba, kuyimfuneko ukusebenzisa izixhobo ezifanelekileyo zokubumba kunye nonyango lomphezulu kwaye ubeke ingqalelo ekukhuseleni nasekuphatheni umphezulu wemveliso egqityiweyo ngexesha lokucubungula.
Iinkcazelo Ngeempawu Zokukhanya ezingalinganiyo:Kwezinye iimeko, ukusetyenzwa kweeplastiki ezikhazimlayo eziphezulu kunokukhokelela kwiipropati ezingalinganiyo zamehlo, ezifana nokubonakala kwenkungu kunye nokuphuma kombala. Ukuyicombulula le ngxaki, kuyimfuneko ukulawula ngokuthe ngqo umgangatho wezinto eziluhlaza, iiparamitha zenkqubo yokucubungula, kunye nonyango olulandelayo lokuqinisekisa ukufana kwezinto ezibonakalayo.
Ezi zezinye zeengxaki eziqhelekileyo ezinokuthi zihlangabezane nazo ngexesha lokusetyenzwa kweeplastiki ezicwebezelayo (optical) eziphezulu. Kusenokubakho ezinye iingxaki ezithile ekufuneka ziqwalaselwe kwaye zisonjululwe kwiimathiriyeli ezahlukeneyo kunye neemeko eziphathekayo. Ebusweni bengxaki yokucutshungulwa kweeplastiki ezikhazimlayo eziphezulu, i-SILIKE iye yaphuhlisa isongezelelo se-silicone eguquliweyo esigcina ukugqiba kunye nokuthungwa kweemveliso zeplastiki ezicwebezelayo ngelixa ikwaphucula ukusebenza.
Igcina ubume obumenyezelayo obuphezulu ngaphandle kokuchaphazela ukugqiba kwemveliso——I-SILIKE lukhetho lokuqala loncedo lokucubungula.
SILIKE SILIMER seriesyimveliso ene-alkyl-modified polysiloxane ene-chain-alkyl-modified namaqela asebenzayo asebenzayo, okanye iimveliso ze-masterbatch ezisekelwe kwii-resin ze-thermoplastic ezahlukeneyo. Ngazo zombini iipropathi ze-silicone kunye namaqela asebenzayo asebenzayo,SILIKE SILIMER iimvelisoidlala indima enkulu ekusetyenzweni kweeplastiki kunye ne-elastomers.
Ngokwenza okugqwesileyo okunje ngokusebenza kakuhle kokuthambisa, ukukhutshwa kakuhle kwe-solo, inani elincinci lokongezwa, ukuhambelana kakuhle neeplastiki, akukho mvula, kwaye kunokunciphisa kakhulu i-coefficient ye-friction, ukuphucula ukuxhathisa ukunxiba kunye nokumelana nokukrweleka komphezulu wemveliso,SILIKE SILIMER iimvelisozisetyenziswa ngokubanzi kwi-PE, PP, PVC, PBT, PET, ABS, PC kunye namacandelo abhityileyo, njl.
Nangona kunjalo,SILIKE SILIMER 5140, luhlobo lwe-wax ye-silicone eguqulwe yi-polyester. esi songezo se-silicone sinokuhambelana kakuhle kunye neninzi ye-resin kunye neemveliso zeplastiki. kwaye igcina ukumelana nokunxiba kakuhle kwe-silicone, kunye nokuzinza okuhle kwe-thermal, kunye neenzuzo zokuphucula ukusebenza ukugcina ukucaca kwezinto kunye nokungafihli, yinto egqwesileyo yangaphakathi ye-lubricant, i-arhente yokukhulula, kunye ne-ejenti yokuxhathisa kunye ne-abrasion yokumelana nokulungiswa kweplastiki.
Xa iiplastiki ezongezelelweyo zifanelekile, ziphucula ukusetyenzwa ngokuziphatha okungcono kokukhutshwa kokubumba, ukuthambisa okulungileyo kwangaphakathi, kunye nokuphucula i-rheology ye-resin melt. umgangatho womphezulu uphuculwa kukukrweleka okuphuculweyo kunye nokumelana nokunxiba, i-COF esezantsi, isicwebezelisi somgangatho ophezulu, kunye nokumanzisa ifayibha yeglasi engcono okanye iibhuleki zefayibha ezisezantsi, Isetyenziswa kakhulu kuzo zonke iintlobo zeemveliso ze-thermoplastic.
Ingakumbi,SILIKE SILIMER 5140ibonelela ngesisombululo esisebenzayo sokusebenza kwi-High-gloss (optical) iiplastiki ze-PMMA, i-PS, kunye ne-PC, ngaphandle kwesiphumo esibi kumbala we-High-gloss (optical) weplastiki okanye ukucaca.
KubaSILIKE SILIMER 5140, amanqanaba okongeza phakathi kwe-0.3 ~ 1.0% acetyiswayo. Ingasetyenziswa kwiinkqubo zokuxuba zokunyibilika kweklasikhi ezifana ne-Single / Twin screw extruders, ukubumba inaliti, kunye nokutya okusecaleni. Umxube womzimba kunye neepellets zepolymer ezinyulu ziyacetyiswa. Ewe kunjalo, kukho iifomyula ezahlukeneyo zeemeko ezahlukeneyo, ke sicebisa ukuba uqhagamshelane no-SILIKE ngokuthe ngqo, kwaye siya kukubonelela ngesisombululo esona sisombululo se-thermoplastic kunye nomgangatho womphezulu!
