Zeziphi izizathu zokuba kutheni amaphepha ePC angaqhekeka okanye aqhekeke ngexesha lokusetyenziswa?
Abahlobo abaninzi banokufumana isenzeko sokugqabhuka kwamaphepha ePC okanye ukuqhekeka emva kokuyifaka kangangexesha elithile emva kokuyithenga? Baya kukrokrela ukuba umgangatho wemveliso awulungile, ngoko baya kuqalisa ukucela umenzi ukuba awubuyisele, kwaye baya kuba nomsindo kakhulu. Kodwa akukhona nje malunga nomgangatho wemveliso, kunokubakho ezinye izizathu zokuqhekeka.
Yintoni kanye kanye eyabangela oko?
1 、 Ukungaphumeleli ukusebenzisa amandla ngexesha lofakelo ngenxa yokugqabhuka.
Ngaphambi kokulungisa ipleyiti ngezikrufu, umngxuma wokulinga kufuneka ugrunjwe ngobubanzi obuyi-6-9mm ubukhulu kunobubanzi be-screw yokulungisa ukunqanda ukwanda kwe-thermal kunye nokucutheka kunye nokuthintela ipleyiti ekugqabhukeni ngenxa yoxinzelelo olugqithisileyo. Iphepha lePC linoxinzelelo olomeleleyo lwangaphakathi, olwenziwa ngexesha lenkqubo yokubumba i-extrusion kunye nokubunjwa kokupholisa, ngelixa ukubonakala kwabo kuhlala kungatshintshi. Ngexesha lokufakwa okanye ukusetyenziswa, baya kungena
Isiphumo sokuthomalalisa uxinezeleko saluphelisa kancinane uxinezeleko lwangaphakathi. Nangona kunjalo, ii-PC sheets eziye zaphumla kancinci kunzima ukuphelisa ngokupheleleyo olu xinzelelo, njengoko zisagcina uxinzelelo olubalulekileyo lwangaphakathi kwaye zongeze uxinzelelo lwangaphandle olwenziwe ngexesha lokusetyenziswa.
Ukuba uxinzelelo luphezulu kakhulu, indawo ye-deformation yendawo iya kwenzeka kwi-surface layer kwaye isondele kumphezulu, okukhokelela kwindawo esengozini. Ngoko ngexesha lenkqubo yokufakela, kunokubangela ukuqhekeka.
2 、 Ukungahoywa kweenkqubo zothutho kunye ne-reservoir nayo yimbangela yokuqhekeka.
I-cushioning echanekileyo, ukupakishwa, kunye nokubekwa kweflethi kuyimfuneko ngexesha lokuthutha kunye nokugcinwa, njengoko nawuphi na umonakalo omncinci kumphezulu wamaphepha e-PC uya kuphuhlisa ukuqhekeka. Kwaye amaphepha e-PC akufuneki agcinwe kwindawo enye njengezinye iikhemikhali, njengoko izinto eziguquguqukayo zinokubangela uxinzelelo lweekhemikhali eziqhekeka kumphezulu we-PC sheets. Amaxwebhu ePC aza kufakwa kwisiza sokwakha nawo kufuneka enziwe ngolu hlobo. Gcina kude nezinto ezine-acidic ezifana nesamente, kwaye ungasebenzisi i-adhesives ene-acidic ngexesha lofakelo.
3 、 Ukukhetha okungafanelekanga kwezixhobo zokusebenza kunokukhokelela ekuqhekekeni.
Kungakhathaliseki ukuba luhlobo luni lokucubungula, izixhobo zokusika okanye izixhobo ezisetyenzisiweyo akufanele zibangele umonakalo kwiindawo ezingacutshungulwayo ze-PC sheet, kwaye ukusika kufuneka kube lula. Ngenxa yokuba nomonakalo omncinci unokukhokelela ekuqhekekeni okukhulu. Ke kwiishedi zangaphandle eziveliswa ziinkampani zamaphepha ePC, ukuba ukusika komphetho kuyafuneka, umatshini wokusika imabhile kufuneka usetyenziswe okanye umatshini wokusila ngesandla kufuneka usetyenziswe, kwaye ukusika kufuneka kube lula.
4 、 Ngethuba lenkqubo yokufakela, ingqwalasela kufuneka ihlawulwe kwezinye iinkcukacha.
1. Musa ukonakalisa okanye ukususa ifilimu ekhuselayo ngaphambi kokufakwa ukuze ugweme ukukrwela umphezulu.
2. Akuvumelekanga ngokupheleleyo ukubethelela ngqo iphepha le-PC kwi-skeleton, ngaphandle koko liya kuvelisa uxinzelelo oluphezulu ngenxa yokwandiswa kwephepha le-PC kwaye lonakalise i-edge perforated.
3. Kuyimfuneko ukusebenzisa i-sealant kunye ne-gasket efanelekileyo kwiplastiki ye-polycarbonate. Ukutywinwa okumanzi kufuneka kusetyenziswe kwiinkqubo zokuhlanganisana ezimanzi. Ngokuqhelekileyo kucetyiswa ukuba kusetyenziswe i-polysiloxane adhesive kwindibano emanzi ye-PCsheets, kodwa ingqalelo ekhethekileyo kufuneka ihlawulwe ukujonga ukuguquguquka kwemichiza ye-adhesive ngaphambi kokusetyenziswa. I-Amino, i-phenylamino, okanye i-methoxy curing agents ayifanele isetyenziswe ukunyanga i-polysiloxane adhesive, njengoko ezi zixhobo zokunyanga zingabangela ukuqhekeka kwephepha, ngakumbi xa kukho uxinzelelo lwangaphakathi. Ungaze usebenzise i-PVC njenge-gasket yokutywina, njengoko iiplasticizers kwi-PVC zinokunyusa kwaye zidle ibhodi, zibangele ukuqhekeka komphezulu kunye nokonakalisa iphepha lonke.
5 、 Amaphepha e-PC axhomekeke ekuqhekekeni xa edibene ne-acids kunye ne-alkali.
I-PC hollow sheets akufanele idibane nezinto ze-alkaline kunye nezinto ezidliwayo eziphilayo ezifana ne-alkali, iityuwa ezisisiseko, i-amines, i-ketones, i-aldehydes, i-esters, i-methanol, i-isopropanol, i-asphalt, njl. Ezi zinto zinokubangela ukuqhekeka koxinzelelo lwekhemikhali.
6 、 Iqondo lokugoba lofakelo aliyi kuba ngaphantsi kweradiyasi echaziweyo.
Ukuba i-radius ye-curvature yephepha le-PC eligobileyo lincinci kakhulu, amandla omatshini kunye nokumelana nemichiza yephepha le-PC kuya kuncipha ngokukhawuleza. Ukuze ugweme ukuqhekeka koxinzelelo oluyingozi kwicala eliveziweyo, iradiyasi yokugoba yephepha lePC kufuneka ingabi ngaphantsi kwedatha ekhankanyiweyo. I-Multi layer PC sheets akufuneki igobe i-perpendicular ukuya kwicala leembambo, njengoko inokuthi ibe mcaba ngokulula okanye iphule iphepha. Iphepha kufuneka ligotywe kwicala leembambo.
Ngethuba nje sisazi isizathu sokuqhekeka, sinokuyithintela ngexesha elifanelekileyo kwaye sithathe amanyathelo okulungisa ngexesha elifanelekileyo.
