Ngaba ukuhanjiswa kweefestile zoomatshini bePC kunokugcinwa ngaphezulu kwe-90% ixesha elide?
Kwimimandla yezixhobo zemizi-mveliso, izixhobo ezikrelekrele, njl.njl., iifestile zoomatshini zePC zithwala uxanduva olubini lokukhusela amacandelo angaphakathi kunye nokuqinisekisa ukucaca kokubonwa. Ukuzinza kwexesha elide lokudluliselwa kwabo kuchaphazela ngokuthe ngqo ukusebenza kokusetyenziswa kwezixhobo. Kodwa ngaba ukuhanjiswa kweefestile koomatshini bePC kunokugcinwa ngaphezulu kwe-90% ixesha elide? Oku kuxhomekeke kwimpembelelo ye-synergistic yezinto ezininzi ezifana nokukhethwa kwezinto, ulawulo lwenkqubo, kunye nokugcinwa kokusetyenziswa.
Izinto zePC ngokwayo zineempawu zokuhambisa ukukhanya kufutshane neglasi. Ukuhanjiswa kokukhanya kokuqala kwezinto ezikumgangatho ophezulu we-PC kunokufikelela malunga ne-90%, ebeka isiseko sokugcina ukukhanya okuphezulu kwexesha elide. Nangona kunjalo, iiPC eziqhelekileyo zineentsilelo zendalo, njengoko amaqela e-ester kunye namakhonkco e-benzene kwisakhiwo sabo se-molecular anovelwano kwimitha ye-ultraviolet. Ukutshatyalaliswa kwexesha elide ekukhanyeni kunokukhokelela ekuphenduleni kwe-oxidation, kubangele ukuphuka kwe-molecular chain kunye nokwakheka kweekhompawundi eziphuzi, ngaloo ndlela kuncitshiswe ukuhanjiswa kokukhanya. Iimvavanyo zibonise ukuba emva kweminyaka engama-3-5 yokusetyenziswa kwangaphandle, ukuhanjiswa kweebhodi zePC ezingaphathwanga kunokuncipha nge-15% -30%, kwaye ngokucacileyo akunakwenzeka ukugcina inqanaba elingaphezulu kwe-90%.
Impumelelo kwitekhnoloji yokuguqulwa kwezinto inika ithuba lokusombulula le ngxaki. I-PC ekwaziyo ukuguga inokuthintela ngokufanelekileyo ukukhanya kwe-ultraviolet kunye nokulibazisa isantya somthubi ngokongeza i-Absorbers ye-UV kunye nezinzisi zokukhanya. Kuvavanyo lokuguga lweyure ye-1000 ye-UV, ukuhanjiswa kwe-PC ekwaziyo ukwaluphala kusezantsi kakhulu kunePC eqhelekileyo. Okubaluleke ngakumbi, itekhnoloji yokukhusela umphezulu, ukugquma kwe-UV kunokwenza umaleko okhuselayo kumphezulu wePC, enokucoca i-99% yemitha ye-UV.
Itekhnoloji yokucubungula inempembelelo enkulu ekuzinzeni kwexesha elide lokuhambisa ukukhanya. Ukuba kukho uxinzelelo lwangaphakathi ngexesha lokucutshungulwa kwePC, kunokukhokelela ekuqhelaneni nokungalingani kwamatyathanga eemolekyuli, ezinokuthi zingabangeli i-birefringence kuphela kodwa ziphinde ziwohloke ukusebenza kwamehlo ngokuhamba kwexesha. Ukongeza, amaqondo obushushu aphezulu aphezulu okanye ukungcola kwimathiriyeli ekrwada kunokubangela ukwehla kokuhanjiswa. Ngokulungisa isitofu sokubumba kunye neenkqubo ze-extrusion, ukulawula ubushushu bokusebenza ngaphakathi kwe-300 ℃, kunye nokuphepha ukunxibelelana nee-ion zetsimbi ezifana nobhedu kunye nentsimbi, umngcipheko wokuthotywa kwezinto unokuncitshiswa, ukuqinisekisa ukuhanjiswa kokukhanya kokuqala kunye nokuzinza kwexesha elide.
Imeko-bume yokusetyenziswa kunye neendlela zokulondoloza zibaluleke ngokufanayo. Kwiindawo eziselunxwemeni ezinetyuwa eninzi okanye indawo engcolisekileyo yemizi-mveliso, amanzi emvula kunye nokukhukuliseka kweekhemikhali kunokunyusa isantya sokuguga kwePC. Kulondolozo lwemihla ngemihla, ukusebenzisa izixhobo ezinzima zokucoca kunokubangela imikrwelo ngokulula kwaye kunciphise nokuhanjiswa kokukhanya. Ukukhetha inqanaba lokukhusela elifanelekileyo lokusingqongileyo kunye nokusetyenziswa kwelaphu elithambileyo lokucoca kunokwandisa ngokufanelekileyo ixesha lokugcinwa kobume obucacileyo obuphezulu.
Isishwankathelo, ingaba ukuhanjiswa kokukhanya kweefestile zomatshini we-PC kunokugcinwa ngaphezu kwe-90% ixesha elide kuxhomekeke ekubeni izinto ezitshintshileyo zokuguga kunye nokukhuselwa kwe-UV yokukhusela zisetyenzisiweyo, nokuba uxinzelelo lwangaphakathi lulawulwa ngokuchaneka kwe-machining, kunye nokuba ukugcinwa kuqhutyelwa ngokudibanisa neempawu zokusingqongileyo. Kwisiseko somgangatho wezinto eziphathekayo, ubugcisa obugqwesileyo, kunye nokugcinwa okufanelekileyo, iifestile zoomatshini zePC zinokufikelela ngokupheleleyo kule njongo, zibonelela ngeziqinisekiso zexesha elide elithembekileyo lokusebenza kwezixhobo zoshishino. Ngokuqhubela phambili okuqhubekayo kobuchwepheshe bezinto eziphathekayo, ixesha lokugcina ukuhanjiswa okuphezulu kuya kuqhubeka kwandiswa.
