Intshayelelo: Imingeni eZingisayo ye-PA/GF Materials
I-Glass fiber reinforced polyamides (PA/GF) lilitye lembombo kwimveliso yanamhlanje ngenxa yamandla azo akhethekileyo omatshini, ukumelana nobushushu, kunye nokuzinza kwe-dimensional. Ukusuka kumacandelo eemoto kunye ne-elektroniki yabathengi ukuya kwizakhiwo ze-aerospace kunye noomatshini bemizi-mveliso, izinto ze-PA/GF zisetyenziswa ngokubanzi kwizicelo zokusebenza eziphezulu ezifuna ukuqina, ukuchaneka, kunye nokuthembeka.
Ngaphandle kwezi ngenelo, izixhobo ze-PA/GF zibonakalisa imingeni eqhubekayo enokuthi ibeke esichengeni ukusebenza kakuhle kwemveliso, umgangatho wemveliso, kunye nokusebenza kokuphela kokusetyenziswa. Amanqaku eentlungu eziqhelekileyo abandakanya i-warpage, ukuhamba kakubi kwe-melt, ukunxiba izixhobo, kunye ne-glass fiber exposure (iintsinga ezidadayo). Le micimbi yandisa imilinganiselo ye-scrap, iphakamisa iindleko zemveliso, kwaye ifuna i-post-processing eyongezelelweyo-imingeni ehlala ichaphazela i-R & D, imveliso, kunye namaqela okuthenga ngokufanayo.
Ukuqonda kunye nokujongana nale mingeni kubalulekile kubavelisi abajolise ekwandiseni ukubanakho kwemathiriyeli ye-PA/GF ngelixa begcina ukusebenza kakuhle kunye nokuhlangabezana nemigangatho engqongqo yobulunga.
I-Pain Point 1: I-Complex and Hard-to-Control Processing
Warpage kunye Deformation
Izinto ze-PA/GF zi-anisotropic kakhulu ngenxa yokuqhelaniswa neentsinga zeglasi. Ngexesha lokupholisa, ukushwabana okungalinganiyo kudla ngokubangela i-warpage kwizinto ezinkulu okanye ezintsonkothileyo zejometri. Oku kubeka esichengeni ukuchaneka komgangatho, kwandisa i-scrap kunye namazinga okusebenza kwakhona, kwaye kudla ixesha kunye nezixhobo. Kwimizi-mveliso efana neemoto kunye ne-aerospace, apho unyamezelo oluluqilima lubalulekile, nephepha lemfazwe elingephi linokubangela ukukhatywa kwecandelo.
Ukuhamba kakubi kweMelt
Ukongezwa kwemicu yeglasi yonyusa kakhulu i-viscosity yokunyibilika, kudala imiceli mngeni yokuhambahamba ngexesha lokubumba inaliti. I-viscosity ephezulu yokunyibilika ingakhokelela ku:
• Izithonga ezimfutshane
• Imigca yokuwelda
• Iziphene zobuso
Le miba iyingxaki ngokukodwa kumalungu anodonga olubhityileyo okanye iinxalenye ezinoyilo oluntsonkothileyo lokungunda. I-viscosity ephezulu ifuna uxinzelelo olukhulu lwenaliti, ukwandisa ukusetyenziswa kwamandla kunye noxinzelelo kwisixhobo sokubumba.
I-Accessed Tool Wear
Iintsinga zeglasi ziyagqabhuka kwaye ziqinile, zikhawuleza ukuguga kwisikhuseli, iimbaleki, kunye nemilomo. Ekubunjweni kwesitofu kunye noshicilelo lwe-3D, oku kunciphisa ubomi bezixhobo, kuphakamisa iindleko zokugcinwa, kwaye kunokunciphisa ixesha lokuvelisa. Kushicilelo lwe-3D, iifilaments eziqulethe i-PA/GF zinokunxiba imilomo ephantsi, echaphazela zombini umgangatho wenxalenye kunye ne-output.
I-Interlayer Bonding enganelanga (ye-3D yoShicilelo):
Kwintsimi yokuvelisa okongeziweyo, i-PA/GF filaments inokuba namava obuthathaka bokubambisana phakathi kweeleya ngexesha lenkqubo yokushicilela. Oku kubangela ukuba kuncitshiswe iimpawu zomatshini zeendawo eziprintiweyo, zibenza bangakwazi ukuhlangabezana namandla alindelekileyo kunye neemfuno zokuqina.
I-Pain Point 2: I-Glass Fiber Exposure kunye ne-Impact yayo
Ukuvezwa kwefiber yeglasi, ekwabizwa ngokuba “ziintsinga ezidadayo,” kwenzeka xa iintsinga ziphuma kumphezulu wepolymer. Le nto inokuchaphazela kakubi i-aesthetics kunye nokusebenza:
Inkangeleko eNcitshiswayo:Imiphezulu ibonakala irhabaxa, ingalingani kwaye ibuthuntu. Oku akwamkelekanga kwizicelo ezifuna isibheno esiphezulu esibonakalayo, esinje ngemoto yangaphakathi, izindlu zombane, kunye nezixhobo zabathengi.
Ukuziva kakubi kweTactile:Umphezulu orhabaxa, okrwempayo wehlisa amava omsebenzisi kunye nomgangatho wemveliso obonwayo.
UkuNcitshiswa koKuhlala:Iintsinga eziveziweyo zisebenza njengezigxininisi zoxinzelelo, zehlisa amandla aphezu komhlaba kunye nokuxhathisa kwe-abrasion. Kwiimeko ezingqongileyo ezirhabaxa (umzekelo, ukufuma okanye ukutyhileka kweekhemikhali), ukuba sesichengeni sefayibha kukhawulezisa ukuguga kwezinto kunye nokwehla kokusebenza.
Le miba ithintela izixhobo ze-PA/GF ukuba zifikelele amandla azo apheleleyo, zinyanzela abavelisi ukuba badibanise phakathi komgangatho, ubuhle, kunye nokusebenza kakuhle kwemveliso.
Izisombululo eziQalayo ze-PA/GF zokuLungiselela imingeni
Inkqubela phambili yamva nje kwisayensi yezinto, itekhnoloji eyongezelelweyo, kunye nobunjineli bonxibelelwano ibonelela ngezisombululo ezisebenzayo kule miba kudala ikho. Ngokudibanisa iikhompawundi ze-PA / GF eziguquliweyo, izongezo ezisekelwe kwi-silicone, kunye ne-fiber-matrix comppatibility enhancers, abavelisi banokunciphisa i-warpage, baphucule ukunyibilika kokunyibilika, kunye nokunciphisa kakhulu ukubonakaliswa kwefiber yeglasi.
1. Izinto eziphantsi kwe-Warp PA/GF
Izinto ezisezantsi ze-PA/GF zenzelwe ngokukodwa ukujongana ne-warpage kunye nokuguqulwa. Ngokulungiselela:

• Ukuhanjiswa kobude beFayibha
• Ubuchwepheshe bonyango lwangaphandle
• I-resin yesakhiwo semolekyuli
olu qulunqo lunciphisa i-anisotropic shrinkage kunye noxinzelelo lwangaphakathi, ukuqinisekisa ukuzinza kwe-dimensional ye-injection eyinkimbinkimbi ye-injection-molded parts. Amanqanaba e-PA6 kunye ne-PA66 enziwe ngokukodwa abonisa ulawulo oluphuculweyo lwe-deformation ngexesha lokupholisa, ukugcina ukunyamezela okuqinileyo kunye nomgangatho wenxalenye engaguqukiyo.
2. High-Flow PA/GF Materials
Izinto ezihamba kakuhle ze-PA/GF zijongana nokuhamba kakubi kwenyibilika ngokubandakanya:
• Izithambiso ezikhethekileyo
• Iiplastiki zeplastiki
• Iipolymers kunye nokusabalalisa ubunzima bemolekyuli emxinwa
Olu hlengahlengiso lunciphisa i-viscosity enyibilikayo, luvumela ukubumba okuntsonkothileyo ukuba kuzalise kakuhle kuxinzelelo olusezantsi lwenaliti. Izibonelelo zibandakanya: iuphuculo lwemveliso, rabafundileyo amazinga eziphene, lukunxitywa kwezixhobo zokusebenza kunye neendleko zokuzigcina.
Ii-Silicone-Based Processing Aids
I-SILIKE izongezo ze-silicone zisebenza njengezithambiso eziphezulu zokusebenza kunye nezixhobo zokusebenza.
Amacandelo abo asebenzayo e-silicone aphucula ukuhanjiswa kwe-filler kunye nokuhamba okunyibilikayo, ukwandisa i-extruder throughput ngelixa kunciphisa ukusetyenziswa kwamandla. Idosi eqhelekileyo: 1-2%, iyahambelana ne-twin-screw extrusion.
Iinzuzo SILIKE'sIi-Silicone-Based Processing Aidskwi-PA6 ene-30%/40% ifayibha yeglasi (PA6 GF30 /GF40):

Zeziphi izongezo ze-silicone ezicetyiswayo zokunciphisa ukuvezwa kwefayibha yeglasi kunye nokuphucula ukunyibilika kokunyibilika kwi-PA/GF kunye nolunye uqulunqo lweplastiki yobunjineli?
I-SILIKE i-Silicone Powder LYSI-100A yindlela yokuncedisa yokusebenza ephezulu
Esi songezo se-silicone sezixhobo ezahlukeneyo ze-thermoplastic, kubandakanywa i-halogen-free flame-retardant wire & cable compounds, i-PVC, iiplastiki zobunjineli, imibhobho, kunye ne-plastic / filler masterbatches. Kwiinkqubo ze-resin ezihambelanayo ne-PA6, esi songezo seplastiki esekwe-silicone sinciphisa i-torque ye-extruder kunye ne-glass fiber exposure, iphucula ukuhamba kwe-resin kunye nokukhululwa kwe-mold, kunye nokuphucula ukuxhathisa kwe-abrasion-ukuhambisa kokubili ukusebenza kakuhle kunye nokusebenza kwemveliso ephezulu.
Isetyenziswe kwiimveliso ze-thermoplastic ezifana ne-PE, PP, PVC, PMMA, PC, PBT, PA, PC / ABS, njl., ukwenzela ukuphuculwa kwenkqubo kunye nokuphucula umgangatho.
Ukongeza i-SILIKE i-Silicone Powder LYSI-100A okanye i-Copolysiloxane Additives and Modifiers SILIMER 5140 ukuya kwi-PA6 GF40 imiqulu inokunciphisa kakhulu ukuvezwa kwefayibha, iphucule ukuzaliswa kokungunda, kunye nokuhambisa uphuculo oluqinisekisiweyo kumgangatho womphezulu, ukuthambisa ukusetyenzwa, kunye nokuqina kwemveliso iyonke.
4. Uphuculo lokuhambelana koNxibelelwano
Ukuncamathela okungalunganga phakathi kweentsinga zeglasi kunye nepolyamide matrix ngoyena nobangela wokuvezwa kwefiber. Ukusebenzisa i-agent edibeneyo yokudibanisa (umz., i-silanes) okanye i-compatibilizers (i-polymers ze-anhydride-grafted) zomeleza i-fiber-matrix bonding, iqinisekisa ukuba iifiber zihlala zifakwe ngexesha lokucubungula. Oku akuphuculi kuphela ubuhle bomphezulu kodwa kwandisa ukusebenza koomatshini kunye nokuqina.
5. IFayibha ende Thermoplastics (LFT)
Ifiber ende ye-thermoplastics (LFT) ibonelela ngenethiwekhi yefiber epheleleyo kunemicu emifutshane, enikezela:
• Amandla aphezulu kunye nokuqina
• Ukunciphisa i-warpage
• Ukuphuculwa kokumelana nempembelelo
Itekhnoloji yale mihla yokuvelisa, kubandakanya i-pultrusion kunye nokubumba inaliti ye-LFT ngokuthe ngqo, iphucule ukuqhubekeka kwe-LFT, iyenza ilungele ukusebenza okuphezulu kunye nezicelo zesakhiwo.
