Indlela Yokuhlanganisa Yendwangu Yokwelula ye-PVC
Indwangu enwetshiwe ye-PVC (i-Polyvinyl Chloride Stretch Fabric) iyinhlanganisela evumelana nezimo eyenziwe ngokuyinhloko nge-polyvinyl chloride (PVC) ngenqubo ekhethekile. Isetshenziswa kabanzi ezinhlelweni ezinjengamatende, izindwangu zokukhangisa, ama-raincoat, nama-awnings. Ukuhlanganiswa kwayo kuhilela izinyathelo ezibalulekile eziningi, okuhlanganisa ukulinganisa kwempahla engavuthiwe, ukuxutshwa, ukwenza ipulasitiki, ukwelula, kanye{2}}nokucubungula kokuthunyelwe. Ukulawulwa okuqinile kwemingcele yenqubo kuyadingeka ukuze kuqinisekiswe ukusebenza komkhiqizo ophelile.
Impahla Engavuthiwe kanye Nokwelashwa Kwangaphambili
Impahla yokuqala eluhlaza yendwangu enwetshiwe ye-PVC i-polyvinyl chloride resin, ivamise ukumiswa noma i-emulsion PVC enesisindo esimaphakathi samangqamuzana nokuzinza okuhle kokushisa. Ukuze kuthuthukiswe ukuguquguquka kwayo, ukumelana nesimo sezulu, nezici zokucubungula, izithasiselo ezihlukahlukene ziyengezwa, okuhlanganisa ama-plasticizers (njenge-phthalates), iziqinisa (njenge-calcium{1}}ezinc complex stabilizers), okothambisa (njenge-stearic acid), izigcwalisi (njenge-calcium carbonate), neziqinisi ze-UV. Lezi zithako kufanele zixutshwe kahle ne-PVC resin ngezilinganiso ezithile ukuze kuqinisekiswe ukuhlakazeka okufanayo.
Ukuxuba kanye Plasticization
Ukuxuba impahla eluhlaza kuyisinyathelo esibalulekile ekuhlanganisweni kwendwangu enwetshiwe ye-PVC. Okokuqala, inhlaka ye-PVC kanye nezithasiselo ezihlukahlukene kubekwa-kumxube wesivinini esikhulu ngokuya ngesilinganiso esihlanganisiwe. Ingxube inyakaziswa ku-80-120℃imizuzu engu-10-20 ukuvumela i-plasticizer ukuthi ingene ngokugcwele ezinhlayiyeni ze-PVC futhi yakhe inhlanganisela eyomile efanayo. Inhlanganisela eyomile bese ingena ku-mixer yangaphakathi noma i-twin-screw extruder ukuze kwenziwe ipulasitiki. Ukushisa nokugunda kuncibilikisa i-PVC ibe iyunifomu yokuncibilika. Izinga lokushisa lepulasitiki livame ukulawulwa phakathi kuka-160-190 degree. Amazinga okushisa aphakeme kakhulu angabangela ukubola kwe-PVC, kuyilapho amazinga okushisa aphansi kakhulu angathinta uketshezi.
Ukunweba
I-PVC eyenziwe ngepulasitiki encibilika ingakhiwa ibe yindwangu eyisisekelo kusetshenziswa i-calendering noma i-blow molding. Ukuthumela ikhalenda kuhilela ukucindezela ukuncibilika nge-multi-ikhalenda ye-roll ibe ifilimu elincanyana, elibe selinenswa into eyisisekelo (njengendwangu elukiwe noma engalukiwe{2}}engalukiwe) bese ipholiswa ukuze yakhe indwangu eyinhlanganisela. Ukwelula kuyisinyathelo esibalulekile ekuthuthukiseni ukuguquguquka kanye ne-ductility yendwangu enwetshiwe ye-PVC. Indwangu eyisisekelo ivamise ukwelulwa ngobude noma ngokuphambana ngaphansi kokushisisa (80-120℃), ngokuvamile izikhathi ezingu-2-3. Ngemva kokwelula, okubalulekile kungena inqubo yokusetha ukushisa ukuze kulungiswe i-orientation ye-molecular chain nokuvimbela ukuncipha.
Okuthunyelwe-Ukucubungula kanye Nokuthuthukisa Ukusebenza
Indwangu eseluliwe ye-PVC eqediwe ithola ukupholisa, ukujikajika, nokwelashwa kwendawo (njengokumbozwa nge-ejenti yokukhulula noma ukuphrinta). Ukuze kuthuthukiswe ukumelana nesimo sezulu, eminye imikhiqizo imbozwe ngezingubo ezifana ne-acrylic noma i-polyurethane. Ngaphezu kwalokho, ukuhlolwa kwekhwalithi okuqinile (njengamandla aqinile, amandla okudabula, nokuhlola ukumelana nezinga lokushisa) kuqinisekisa ukuthi umkhiqizo uhlangabezana nezindinganiso zohlelo lokusebenza.
Indlela yokuhlanganisa yendwangu enwetshiwe ye-PVC ifinyelela-okubalulekile okusebenza okuphezulu okuhlanganisa ukuguquguquka, ukumelana namanzi, nokuqina ngokulawula ngokunembile isilinganiso sempahla eluhlaza, izinga lokushisa lokucubungula, nesenzo somshini, ekugcineni kuhlangatshezwane nezidingo zezimboni ezihlukahlukene.
