Intshayelelo: Imingeni eqhubekayo yezixhobo ze-PA/GF
Iipolyamides eziqinisiweyo ngefayibha yeglasi (PA/GF) zibaluleke kakhulu kwimveliso yanamhlanje ngenxa yamandla azo angaqhelekanga oomatshini, ukumelana nobushushu, kunye nozinzo olulinganayo. Ukususela kwizinto zeemoto kunye ne-elektroniki yabathengi ukuya kwizakhiwo zeenqwelo moya kunye noomatshini bemizi-mveliso, izixhobo ze-PA/GF zisetyenziswa kakhulu kwizicelo zokusebenza okuphezulu ezifuna ukuqina, ukuchaneka, kunye nokuthembeka.
Nangona ezi zibonelelo zilungile, izixhobo ze-PA/GF zizisa imingeni eqhubekayo enokuphazamisa ukusebenza kakuhle kwemveliso, umgangatho wemveliso, kunye nokusebenza kokusetyenziswa kokugqibela. Iindawo ezibuhlungu eziqhelekileyo ziquka ukugoba, ukuhamba kakubi kokunyibilika, ukuguguleka kwezixhobo, kunye nokuvezwa kwefayibha yeglasi (iifayibha ezidadayo). Ezi ngxaki zonyusa amaxabiso ezinto ezilahliweyo, zinyusa iindleko zemveliso, kwaye zifuna ezinye iingxaki emva kokucubungula—imingeni edla ngokuchaphazela amaqela e-R&D, imveliso, kunye nokuthengwa kwempahla ngokufanayo.
Ukuqonda nokujongana nale mingeni kubalulekile kubavelisi abajonge ukwandisa amandla ezixhobo ze-PA/GF ngelixa begcina ukusebenza kakuhle kwaye behlangabezana nemigangatho yomgangatho ongqongqo.
Inqaku leNtlungu 1: Ukucubungula okuNzima nokuLula
I-Warpage kunye ne-Deformation
Izinto ze-PA/GF zinoburhalarhume obukhulu ngenxa yokujongwa kweefayibha zeglasi. Ngexesha lokupholisa, ukuncipha okungalinganiyo kudla ngokubangela ukugoba kwiindawo ezinkulu okanye ezintsonkothileyo ngokwejiyometri. Oku kuphazamisa ukuchaneka kobukhulu, kwandisa amazinga okulahla nokuphinda kusetyenziswe izinto ezintsha, kwaye kudla ixesha kunye nezixhobo. Kumashishini afana neemoto kunye neenqwelo-moya, apho ukunyamezelana okuncinci kubaluleke kakhulu, nokuba ukugoba okuncinci kunokubangela ukwaliwa kwezixhobo.
Ukuhamba Kakubi Kokunyibilika
Ukongezwa kweefayibha zeglasi kwandisa kakhulu ukunyibilika, nto leyo edala iingxaki zokukwazi ukuhambahamba ngexesha lokubumba ngenaliti. Ukunyibilika okuphezulu kunokukhokelela koku:
• Iifoto ezimfutshane
• Imigca yokuwelda
• Iziphene zomphezulu
Ezi ngxaki zinzima ngakumbi kwiindawo ezincinci okanye kwiindawo ezineedizayini ezintsonkothileyo zokubumba. Ubuninzi be-viscosity bufuna uxinzelelo olukhulu lokujova, ukonyusa ukusetyenziswa kwamandla kunye noxinzelelo kwizixhobo zokubumba.
Ukunxiba Izixhobo Okukhawulezileyo
Iifayibha zeglasi ziyarhabaxa kwaye ziqinile, zikhawulezisa ukuguguleka kwiimolds, runners, kunye neenozzles. Kwi-injection molding kunye ne-3D printing, oku kunciphisa ubomi bezixhobo, kunyusa iindleko zokugcinwa, kwaye kunokunciphisa ixesha lokusebenza kwemveliso. Kwi-3D printing, ii-filaments ezine-PA/GF zinokuguguleka iinozzles, zichaphazele umgangatho wenxalenye kunye nomthamo.
Ukudityaniswa kwe-Interlayer okunganelanga (kwe-3D Printing):
Kwicandelo lokwenziwa kwezinto ezongeziweyo, iifilaments ze-PA/GF zinokuba nengxaki yokubophana okubuthathaka phakathi kweeleya ngexesha lenkqubo yokuprinta. Oku kubangela ukuncipha kweempawu zoomatshini zeendawo eziprintiweyo, nto leyo ebangela ukuba zingakwazi ukuhlangabezana neemfuno zamandla nokuqina ezilindelekileyo.
Inqaku leNhlungu 2: Ukuvezwa kweFayibha yeGlasi kunye neMpembelelo yayo
Ukuvezwa kwefayibha yeglasi, okwaziwa ngokuba “ziifayibha ezidadayo,” kwenzeka xa iifayibha ziphuma kumphezulu wepolymer. Le nto inokuchaphazela kakubi ubuhle kunye nokusebenza:
Inkangeleko Ebuthathaka:Imiphezulu ibonakala irhabaxa, ingalingani, kwaye ibuthuntu. Oku akwamkelekanga kwiizicelo ezifuna ukubonakala okuphezulu, ezifana nengaphakathi leemoto, izindlu ze-elektroniki, kunye nezixhobo zabathengi.
Imvakalelo Engathandekiyo Yokuchukumisa:Iindawo ezirhabaxa nezikrwelayo zinciphisa amava omsebenzisi kunye nomgangatho wemveliso obonwayo.
Ukuqina Okunciphileyo:Iifayibha eziveziweyo zisebenza njengezixinanisi zoxinzelelo, zinciphisa amandla omphezulu kunye nokumelana nokurhawuzelelwa. Kwiimeko ezinzima (umz., ukufuma okanye ukuvezwa ziikhemikhali), ukuvezwa kweefayibha kukhawulezisa ukuguga kwezinto kunye nokuwohloka kokusebenza.
Ezi ngxaki zithintela izixhobo ze-PA/GF ekufikeleleni kwisakhono sazo esipheleleyo, nto leyo enyanzela abavelisi ukuba bayeke phakathi komgangatho, ubuhle, kunye nokusebenza kakuhle kwemveliso.
