Yiziphi izizathu zokuthi kungani amashidi e-PC angaqhekeka noma aqhekeke phakathi nokusetshenziswa?

Abangane abaningi bangase bahlangabezane nesenzakalo sokuqhuma noma ukuqhekeka kwamashidi e-PC ngemva kokuwafaka isikhathi esithile ngemva kokuwathenga? Bazosola ukuthi ikhwalithi yomkhiqizo ayilungile, ngakho bazoqala ukucela umenzi ukuthi awubuyisele, futhi bazothukuthela kakhulu. Kodwa akukhona nje ngekhwalithi yomkhiqizo, kungase kube nezinye izizathu zokuqhekeka.

Yini ngempela eyabangela?

1 、 Ukwehluleka ukusebenzisa amandla ngesikhathi sokufakwa ngenxa yokugqabuka.

Ngaphambi kokulungisa ipuleti ngezikulufu, imbobo yokuhlola kufanele ibhodwe ngobubanzi obungu-6-9mm obukhulu kunobubanzi besikulufu sokulungisa ukuze kuvinjelwe ukunwetshwa okushisayo nokufinyela futhi kuvinjwe ipuleti ukuthi lingaqhumi ngenxa yokucindezela okukhulu. Ishidi le-PC linokucindezeleka okuqinile kwangaphakathi, okwakhiwa phakathi nenqubo yokubunjwa kwe-extrusion nokubunjwa kokupholisa, kuyilapho ukubukeka kwabo kuhlala kungashintshiwe. Ngesikhathi sokubekwa noma ukusetshenziswa, zizobhekana

Umphumela wokuphumuza ingcindezi uqede ukucindezeleka kwangaphakathi kancane. Kodwa-ke, amashidi e-PC athole ukuphumula okulinganiselwe kuphela kunzima ukuqeda ngokuphelele lezi zingcindezi, njengoba esagcina ukucindezeleka okukhulu kwangaphakathi bese engeza ukucindezeleka kwangaphandle okukhiqizwa ngesikhathi sokusetshenziswa.

Uma ukucindezeleka kuphezulu kakhulu, indawo ye-deformation yendawo izokwenzeka kungqimba olungaphezulu futhi isondele phezulu, okuholela endaweni esengozini. Ngakho phakathi nenqubo yokufaka, kungase kubangele nokuqhekeka.

2 、 Ukunganaki izinqubo zokuthutha kanye ne-reservoir nakho kuyimbangela yokuqhekeka.

I-cushioning efanele, ukupakishwa, nokubeka isicaba kuyadingeka ngesikhathi sokuthutha nokugcinwa, njengoba noma yimuphi umonakalo omncane ebusweni bamashidi e-PC uzokhula ube imifantu. Futhi amashidi e-PC akufanele agcinwe endaweni efanayo namanye amakhemikhali, njengoba izinto eziguquguqukayo zingabangela ukuqhekeka kwamakhemikhali ebusweni bamashidi e-PC. Amashidi e-PC azofakwa esizeni sokwakha nawo kumele enziwe ngale ndlela. Ziqhelelanise nezinto ezine-acidic njengosimende, futhi ungasebenzisi izinto ezinamathelayo ezine-asidi ngesikhathi sokufakwa.

3 、 Ukukhetha okungalungile kwamathuluzi okucubungula nakho kungaholela ekuqhekekeni.

Kungakhathaliseki ukuthi hlobo luni lokucubungula, amathuluzi okusika noma izinsimbi ezisetshenzisiwe akumele zibangele noma yimuphi umonakalo ezingxenyeni ezingacutshunguliwe zeshidi le-PC, futhi ukusika kufanele kube bushelelezi. Ngoba ngisho nomonakalo omncane ungaholela ekuqhekekeni okukhulu. Ngakho-ke kumashede angaphandle akhiqizwa izinkampani zamashidi e-PC, uma ukusika onqenqemeni kuyadingeka, umshini wokusika imabula kufanele kusetshenziswe noma kusetshenziswe umshini wokugaya isandla, futhi ukusika kufanele kube bushelelezi.

4 、 Phakathi nenqubo yokufaka, ukunakwa kufanele kukhokhwe eminye imininingwane.

1. Ungalimazi noma ukhiphe ifilimu evikelayo ngaphambi kokuyifaka ukuze ugweme ukunwaya indawo engaphezulu.

2. Akuvunyelwe nakancane ukubethela ishidi le-PC ku-skeleton, ngaphandle kwalokho kuzodala ukucindezeleka okukhulu ngenxa yokwandiswa kweshidi le-PC futhi kulimaze unqenqema olunezimbobo.

3. Kuyadingeka ukusebenzisa i-sealant ne-gasket efanelekile ipulasitiki ye-polycarbonate. I-Wet sealant kufanele isetshenziswe ezinhlelweni zokuhlanganisa ezimanzi. Ngokuvamile kunconywa ukusebenzisa i-polysiloxane enamathelayo ekuhlanganiseni okumanzi kwama-PCsheets, kodwa ukunaka okukhethekile kufanele kukhokhwe ekuhloleni ukuguquguquka kwamakhemikhali okunamathelayo ngaphambi kokusetshenziswa. Ama-amino, i-phenylamino, noma ama-methoxy elaphayo akufanele nanini asetshenziselwe ukwelapha i-polysiloxane adhesive, njengoba lawa ma-ejenti elaphayo angabangela ukuqhekeka kweshidi, ikakhulukazi uma kunengcindezi yangaphakathi. Ungalokothi usebenzise i-PVC njenge-gasket yokuvala, njengoba ama-plasticizers ku-PVC angakwazi ukushona phansi futhi onakalise ibhodi, abangele ukuqhekeka phezulu futhi kulimaze ishidi lonke.

5 、 Amashidi e-PC athambekele ekuqhekekeni lapho ethintana nama-acids nama-alkali.

Amashidi angenalutho e-PC akufanele ahlangane nezinto ze-alkaline nezinto eziphilayo ezonakalisayo ezifana ne-alkali, usawoti oyisisekelo, ama-amine, ama-ketone, ama-aldehydes, ama-esters, i-methanol, i-isopropanol, i-asphalt, njll. Lezi zinto zingabangela ukuqhekeka kokucindezeleka kwamakhemikhali okukhulu.

6 、 Idigri yokugoba yokufaka akufanele ibe ngaphansi kwerediyasi eshiwo.

Uma i-curvature radius yeshidi le-PC egobile incane kakhulu, amandla emishini nokumelana kwamakhemikhali kweshidi le-PC kuzokwehla kakhulu. Ukuze ugweme ukuqhekeka kwengcindezi eyingozi ohlangothini oluveziwe, irediyasi egobayo yeshidi le-PC akumele ibe ngaphansi kwedatha eshiwo. Amashidi e-PC anezingqimba eziningi akumele agobe aqonde lapho izimbambo zibheke ngakhona, ngoba angakwazi ukucaba kalula noma aphule ishidi. Ishidi kumele ligotshwe libheke ezimbanjeni.

Uma nje siyazi imbangela yokuqhekeka, singakuvimbela ngesikhathi futhi sithathe izinyathelo zokulungisa ngesikhathi esifanele.
