I-Fire Extinguisher Cylinder Inner Thermoplastic Coating

Amasilinda okucima umlilo ngokuvamile enziwa ngensimbi, njengensimbi noma i-aluminium, futhi adizayinelwe ukuqukatha isicisha-mlilo esisetshenziselwa ukucisha imililo. Nokho, amanye amasilinda okucima umlilo angase abe nengaphakathi i-thermoplastic coating, esetshenziswa ngaphakathi kwesilinda ukuze kuvikelwe ukugqwala nokuthuthukisa ukusebenza kwe-ejenti yokucisha.

Ingubo ye-thermoplastic esetshenziswa kumasilinda okucima umlilo imvamisa iyi-polymer ye-polyethylene noma into enayiloni. Lezi zinto zikhethwa ngenxa yokuqina kwazo, ukumelana namakhemikhali, namandla okumelana namazinga okushisa aphezulu. I-coating isetshenziswa ngaphakathi kwesilinda kusetshenziswa inqubo ebizwa ngokuthi i-rotational molding, lapho i-powder coating ishisa futhi ijikeleziswa ngaphakathi kwe-cylinder kuze kube yilapho incibilika futhi yakha isendlalelo esifanayo.

Ukusetshenziswa kwe-inner thermoplastic coating kumasilinda okucima umlilo kunganikeza izinzuzo eziningana. Okokuqala, kusiza ukuvikela isilinda ekugqwaleni, okungabangelwa i-ejenti yokucisha noma ukuchayeka kumswakama. Ukugqwala kungawenza buthaka isilinda futhi kunciphise amandla ayo okuqukatha isicisha-mlilo ngokuphumelelayo, okungafaka engozini ukusebenza kwayo esimweni esiphuthumayo.

Okwesibili, i-thermoplastic coating ingathuthukisa ukusebenza kwe-ejenti yokucisha. Isibonelo, ku-carbon dioxide (CO2) izicishamlilo zomlilo, ukunamathela kungavimbela i-CO2 ekuphenduleni ngensimbi yesilinda, okungabangela ukuba isilinda sibe buthaka noma siqhume. Ukwengeza, ukunamathela kungasiza ekunciphiseni inani le-CO2 eliphuma kusilinda ngesikhathi sokusetshenziswa, okungathuthukisa ukusebenza kahle kwesicishamlilo.

Kodwa-ke, kukhona ukukhathazeka mayelana nokuphepha kwezingubo ze-thermoplastic kumasilinda okucima umlilo. Uma ukugqoka kungasetshenziswa ngendlela efanele noma konakalisiwe, kungaxebuka noma kuqhume, okungase kungcolise i-ejenti yokucisha futhi kubangele ukungasebenzi kahle. Ukwengeza, uma ukumboza kuvezwe emazingeni okushisa aphezulu noma amalangabi, kungakhipha intuthu enobuthi, engaba yingozi kubantu nasendaweni ezungezile.

Ukuqinisekisa ukuphepha nokusebenza kahle kwamasilinda okucima umlilo anezingubo zangaphakathi ze-thermoplastic, kubalulekile ukulandela izinqubo ezifanele zokugcinwa nokuhlola. Amasilinda kufanele ahlolwe njalo ukuze kubonakale izimpawu zomonakalo noma ukugqwala, futhi noma yikuphi ukukhubazeka kufanele kulungiswe ngokushesha. Ukwengeza, izicishamlilo kufanele zisetshenziswe kuphela ngokuhambisana neziqondiso zomkhiqizi futhi kufanele zigcinwe futhi zihanjiswe ngokuphepha ukuze zigweme ukulimala kokunameka.

Ekuphetheni, ukusetshenziswa kwengubo yangaphakathi ye-thermoplastic kumasilinda okucima umlilo kunganikeza izinzuzo eziningana, njengokuvikela ukugqwala nokuthuthukisa ukusebenza kwe-ejenti yokucima umlilo. Kodwa-ke, kunokukhathazeka ngokuphepha kwalezi zimbotshana, ikakhulukazi uma zonakalisiwe noma zivezwe emazingeni okushisa aphezulu. Kubalulekile ukulandela ukugcinwa okufanele kanye nezinqubo zokuhlola ukuqinisekisa ukuphepha nokusebenza kahle kwamasilinda okucima umlilo anezingubo zangaphakathi ze-thermoplastic.

PECOAT® I-Fire Extinguisher Cylinder Inner Thermoplastic Coating iyi-polymer esekelwe kwi-polyolefin, eyenzelwe ukusetshenziswa ngolwelwesi olujikelezayo kumasilinda ensimbi ukuze inikeze ulwelwesi oluvikelayo olukwazi ukumelana kahle kakhulu nezindawo ezinamanzi, okuhlanganisa ne-agent ekhipha amagwebu i-AFFF futhi futhi imelana nokufika ku-30% I-Antifreeze ( i-ethylene glycol). Uma isetshenziswe kahle, ukunamathela kunikeza ukunamathela okuhle kakhulu ngaphandle kwesidingo se-priming coat ehlukile futhi ingamelana nezinga lokushisa elizinzile noma lokuhamba ngebhayisikili phakathi -40 ° C kanye +65 ° C.
