Ungakhetha kanjani i-valve efanele ye-aerosol?(isayensi)
Ngokusho kweBritish Aerosol Manufacturers Association (BAMA), namuhla kunemikhiqizo ye-aerosol engaphezu kuka-200 esetshenziswa emikhakheni yomuntu siqu, ekhaya, ezimbonini, ezolimo, ezokwakha, ezomlilo, ezokuphepha, ezokwelapha nakweminye imikhakha.
I-valve ye-aerosol ibonakala ingabalulekile, kodwa ngokuhlobene nawo wonke umkhiqizo we-aerosol uyinto ebaluleke kakhulu, hhayi kuphela ehlobene nokubeka uphawu komkhiqizo, kodwa futhi ihlobene nomphumela we-ejection, yiqiniso, futhi ihlobene nokuzinza kwawo wonke umkhiqizo we-aerosol.Ngakho-ke, indlela yokukhetha i-valve efanele kufanelekile ekuthuthukiseni imikhiqizo ye-aerosol.
Amaphesenti angu-90 ama-valve asetshenziswa eNyakatho Melika akhiqizwa yi-Percision, Seaquist and Summit, kanti amanye akhiwe ngabakwa-Newman-Green, Bespak, Beardg, Emson, Riker and Coster.I-Seaquist yangena ku-Aptar Group, eyathola u-Emson ngo-1999. Abahlinzeki abaziwayo emakethe futhi bahlanganisa uLindal, uMitani, njll. Futhi i-valve yasekhaya ivela ikakhulukazi e-United States, ukunemba, i-cimB nabanye abakhiqizi.
Uma kusukela esigabeni se-valve, i-aerosol ihlukaniswa ngokuyinhloko izigaba ezimbili: eyodwa nezimbili.Isakhiwo esikhulu se-aerosol ye-yuan sihlanganisa: ithangi, i-valve, ikhava yangaphandle, inkinobho yokusunduza, i-projectile agent, umzimba wezinto ezibonakalayo.Imiphumela eyinhloko ye-aerosol kanambambili ihlanganisa: ithangi, i-valve, isikhwama se-aluminium ye-multilayer, ikhava yangaphandle, inkinobho yokusunduza, umzimba wezinto ezibonakalayo, igesi ecindezelwe.
I-valve ngokuvamile ihlanganisa: inkomishi yokuvala, i-gasket yangaphandle, i-gasket yangaphakathi, isiqu, intwasahlobo, igumbi le-valve, utshani nezinye izingxenye eziyisikhombisa, kucatshangelwa izinto ezihlukahlukene, ubukhulu kanye nesakhiwo nezinye izici, inkolelo-mbono ye-valve ingabonisa amashumi ezigidigidi ze-valve. izinguquko ezahlukene.
Ngakho-ke, indlela yokukhetha i-valve efanele idinga ukucabangela izici ezilandelayo:
Okokuqala: i-valve yedola elilodwa noma i-valve kanambambili?
Engxubeni yezinto ezibonakalayo kanye ne-ejenti ye-projectile, ukuhambisana kwefomula yezinto ezibonakalayo kufanele kucatshangelwe.Lapho i-ejenti ye-projectile kanye nokuqukethwe kufuthwa ngesikhathi esifanayo, kulula ukukhiqiza ukuthi i-ejenti ye-projectile ifuthwe, futhi umzimba wezinto ezibonakalayo usasele, othinta isipiliyoni somthengi.Ayikwazi ukusetshenziswa 360 degrees, ingasetshenziswa kuphela ngaphambili noma sibheke phansi.I-ejenti eguquguqukayo ye-parabolic (i-propylene butane noma i-dimethyl ether), ingcindezi izokhula ngokwejometri ngokukhuphuka kwezinga lokushisa, ingeyempahla eyingozi, izimo zokuhamba nezokugcina zinezidingo eziqinile.
Ngaphandle kwezindleko, ama-valve kanambambili anezinzuzo eziningi: isibonelo:
Okuqukethwe akuthinti ngokuqondile ithangi le-aerosol, okwenza isivikelo emzimbeni wezinto ezibonakalayo;
Ukukhipha nxazonke, ukuzivumelanisa nesimo sokusetshenziswa okuhlukahlukene;
Isikhwama se-vacuum valve ngaphambi kokugcwalisa, singaphinde sifakwe i-cobalt 60 disinfection, ifomula inganciphisa ama-preservatives, ukunciphisa umthombo we-allergenic;
Ukucindezela njalo ethangini, ukukhishwa okuzinzile, izinsalela zomzimba eziphansi;
Ngomoya ocindezelwe noma i-nitrogen, ingcindezi icishe ibe njalo njengoba izinga lokushisa likhuphuka, futhi izidingo zokuhamba nokugcinwa ziphansi kakhulu.
Okwesibili: ukukhethwa kwempahla yenkomishi yokuvala?
Izinkomishi zensimbi ngokuvamile ziba ngu-0.27mm ubukhulu kanti izinkomishi ze-aluminium zingu-0.42mm ubukhulu.Izicelo zokunakekelwa komuntu siqu zivame ukusebenzisa izinkomishi ze-aluminium, ezinzile futhi ezingavamile ukugqwala.Ukuzinza kosayizi wenkomishi yensimbi kungcono, futhi akulula ukuthintwa yi-tank noma inqubo yokuvala inkomishi;
Okwesithathu: impahla ye-gasket
Ama-gaskets ngokuvamile ahlukaniswe ngama-gaskets angaphakathi nama-gaskets angaphandle, izinto ezihlukahlukene, ikakhulukazi: i-butyl, i-chloroprene, i-butyl, i-chloroprene, i-nitrile, i-chloroprene, i-polyurethane nokunye.I-Gasket shrinkage izothinta ukulingana kwe-stem gasket, ngezinye izikhathi okuholela ekuvuzeni.Uma i-gasket ikhula ngokweqile, imbobo ye-valve stem ye-gasket ayikwazi ukudalulwa lapho i-nozzle icindezelwa, okuzothinta ukusebenza kahle komjovo.Ngemuva kokuhlolwa okuphindaphindiwe, igolide lihlolwe ngengxube ye-ethanol engu-75% kanye ne-25% isopentane, futhi ukukhetha okungcono kakhulu kwakuyirabha ezinzile ye-NEOPRENE ne-BUNA.
Okwesine: ukuvuleka kwesiqu
Osayizi abavamile bangu-0.35, 0.4, 0.46, 0.51, 0.61mm, futhi inani lezimbobo ze-stem lingenye yezinto ezinquma izinga lokugeleza.Inombolo yezimbobo ze-stem iyatholakala futhi ochungechungeni oluhlukene, enezimbobo ezingu-1,2,4,6 ngisho nezingu-8.
Okwesihlanu: eceleni kwembobo yevalvu
Imbobo eseceleni yesigaba segesi itholakala emzimbeni wegumbi le-valve, futhi itholakala ngaphakathi ngemva kokuvalwa kwe-valve.Ngokuyinhloko isetshenziselwa ukwandisa umphumela we-atomization, ukwandisa ukuzinza kokukhishwa kokuqukethwe kweminye imikhiqizo yempushana, nokwandisa ukukhishwa kwemikhiqizo ye-viscosity ephezulu.Itholakala ngemiklamo yembobo eyodwa futhi kabili.
Inombolo yesithupha: Ubude botshani
Esimisweni sokuqala singasuselwa kubude be-valve = ukuphakama okuphelele kwembiza - inani elibekiwe.Ubude be-valve yokugcina kufanele bube ngaphansi kwe-1/3 ye-semi-circle ngaphansi kwethangi ngemva kokuzinza phansi kotshani ngokucwiliswa emanzini.
Uma kucatshangelwa ukuthi ama-straws anokwandiswa okungu-3-6%, kubalulekile ukuqinisekisa ubude ngemuva kokuhlolwa kokuhambisana, futhi vele umklamo we-bevel cut straws nawo ungasiza kancane.
Ngezinkinobho ezifanele, i-valve ekhethiwe ingaletha izici ze-aerosol kumthengi.Njengohlelo lwephakheji lomkhiqizo oyinkimbinkimbi, ludinga ukuhlola ukuhambisana nokuzinza ukuze udizayine umkhiqizo omangalisayo!
