Indlela yokukhetha ivalve efanelekileyo ye-aerosol?(isayensi)
Ngokutsho kweBritish Aerosol Manufacturers Association (BAMA), namhlanje kukho ngaphezu kwe-200 yeemveliso ze-aerosol ezisetyenziselwa umntu, ikhaya, ishishini, ukulima, ukwakhiwa, umlilo, ukhuseleko, unyango kunye nezinye iinkalo.
I-valve ye-aerosol ibonakala ingabalulekanga, kodwa ngokumalunga nayo yonke imveliso ye-aerosol iyona nto ibaluleke kakhulu, ingahambelani kuphela nokutywinwa kwemveliso, kodwa inxulumene nefuthe le-ejection, ngokuqinisekileyo, inxulumene nokuzinza kwayo yonke imveliso ye-aerosol.Ngoko ke, indlela yokukhetha i-valve efanelekileyo ifanelekile ingqalelo ekuphuhlisweni kweemveliso ze-aerosol.
Amashumi alithoba eepesenti yeevalvu ezisetyenziswa kuMntla Melika zenziwa yiPercision, Seaquist and Summit, kunye nezinye zenziwe nguNewman-Green, Bespak, Beardg, Emson, Riker kunye neCoster.I-Seaquist morphed kwi-Aptar Group, eyafumana u-Emson ngo-1999. Ababoneleli abaziwayo kwiimarike baquka i-Lindal, i-Mitani, njl.
Ukuba ukusuka kudidi lwevalve, i-aerosol yahlulahlulwe ikakhulu ngamacandelo amabini: enye kunye neyesibini.Ulwakhiwo oluphambili lweyuan aerosol lubandakanya: itanki, ivalve, isigqubuthelo sangaphandle, iqhosha lokutyhala, iarhente yeprojekti, umzimba wezinto.Iziphumo eziphambili ze-aerosol ye-binary ziquka: itanki, i-valve, i-multilayer aluminium bag, ikhava yangaphandle, iqhosha lokutyhala, umzimba wezinto eziphathekayo, igesi ecinezelweyo.
I-valve idla ngokubandakanya: ikomityi yokutywina, i-gasket yangaphandle, i-gasket yangaphakathi, i-stem, i-spring, igumbi le-valve, i-straw kunye nezinye iindawo ezisixhenxe, kuthathelwa ingqalelo izinto ezahlukeneyo, ubungakanani kunye nolwakhiwo kunye nezinye izinto, ithiyori yevalve ingabonisa amashumi ezigidi ze utshintsho ezahlukeneyo.
Ngoko ke, indlela yokukhetha i-valve efanelekileyo kufuneka iqwalasele ezi zinto zilandelayo:
Okokuqala: ivalve yedola enye okanye ivalve yokubini?
Kumxube wezinto eziphathekayo kunye ne-projectile agent, ukuhambelana kwefomula yezinto eziphathekayo kufuneka kuthathelwe ingqalelo.Xa i-agent ye-projectile kunye nomxholo ifafazwa ngexesha elifanayo, kulula ukuvelisa ukuba i-agent ye-projectile iye yatshizwa, kwaye umzimba wezinto eziphathekayo uhleli, ochaphazela amava omthengi.Ayinakusetyenziswa i-360 degrees, ingasetyenziswa kuphela ngaphambili okanye phezulu.I-agent eguquguqukayo ye-parabolic (i-propylene butane okanye i-dimethyl ether), uxinzelelo luya kunyuka ngejometri ngokunyuka kweqondo lokushisa, liyimpahla enobungozi, iimeko zokuthutha kunye nokugcinwa zineemfuno eziqinileyo.
Nokuba zithini na iindleko, iivalve zokubini zineenzuzo ezininzi: umzekelo:
Iziqulatho aziqhagamshelani ngokuthe ngqo netanki ye-aerosol, yenze ukhuseleko kumzimba wezinto eziphathekayo;
I-ejection ejikelezileyo, iqhelanise nemeko yokusetyenziswa kwezinto ezahlukeneyo;
Isikhwama se-vacuum valve ngaphambi kokuzaliswa, sinokuphinda sihlanjululwe yi-cobalt 60 ye-disinfection, i-formula inokunciphisa i-preservatives, ukunciphisa umthombo we-allergenic;
Uxinzelelo oluqhubekayo kwitanki, i-ejection ezinzileyo, intsalela yempahla ephantsi;
Ngomoya oxinanisiweyo okanye initrogen, uxinzelelo luphantse lube rhoqo njengoko iqondo lobushushu linyuka, kwaye iimfuno zokuthutha kunye nokugcinwa ziphantsi.
Okwesibini: ukhetho lwempahla yekomityi yokutywina?
Iikomityi zentsimbi zidla ngokuba yi-0.27mm ubukhulu kwaye iikomityi ze-aluminiyam ziyi-0.42mm ubukhulu.Izicelo zokhathalelo lomntu zihlala zisebenzisa iikomityi ze-aluminium, ezizinzile kwaye zincinci kakhulu kwi-corrosion.Ukuzinza kobungakanani bekomityi yentsimbi kungcono, kwaye akulula ukuchatshazelwa yitanki okanye inkqubo yokutywinwa kwekomityi;
Okwesithathu: izinto zegasket
I-Gaskets idla ngokuhlula kwii-gaskets zangaphakathi kunye ne-gaskets yangaphandle, izinto ezihlukeneyo, ngokukodwa: i-butyl, i-chloroprene, i-butyl, i-chloroprene, i-nitrile, i-chloroprene, i-polyurethane kunye nokunye.I-Gasket shrinkage iya kuchaphazela i-stem gasket fit, ngamanye amaxesha ikhokelela ekuvuzeni.Ukuba i-gasket ikhula ngokugqithiseleyo, i-valve stem hole ye-gasket ayinakubonakaliswa xa i-nozzle icinezelekile, eya kuchaphazela ukusebenza kakuhle kwe-injection.Emva kwezilingo eziphindaphindiweyo, igolide yavavanywa ngomxube we-75% ye-ethanol kunye ne-25% ye-isopentane, kwaye ukhetho oluhle kakhulu lwaluyi-rubber ezinzileyo ye-NEOPRENE kunye ne-BUNA.
Okwesine: ukuvuleka kwesikhondo
Ubukhulu obuqhelekileyo buyi-0.35, 0.4, 0.46, 0.51, 0.61mm, kwaye inani lemingxuma ye-stem yenye yezinto ezibonisa izinga lokugubungula.Inani lemingxuma yesikhondo likwafumaneka kuthotho olwahlukileyo, kunye ne-1,2,4,6 kunye nemingxuma esi-8.
Okwesihlanu: ecaleni komngxuma wevalve
Umngxuma wesigaba segesi ubekwe kumzimba wegumbi levalvu, kwaye ungaphakathi emva kokuba ivalve ivalwe.Isetyenziselwa kakhulu ukunyusa umphumo we-atomization, ukunyusa ukuzinza kwe-ejection yomxholo wezinye iimveliso ze powder, kunye nokwandisa ukukhutshwa kweemveliso eziphezulu ze-viscosity.Ifumaneka kuyilo lomngxunya omnye kunye nambini.
Inani lesithandathu: Ubude bendiza
Kwilungiselelo lokuqala kunokusekwa kubude bevalve = ubude obupheleleyo bejagi - ixabiso lexabiso.Ubude bevalve yokugqibela kufuneka bube ngezantsi kwe-1/3 yesiqingatha sesangqa ezantsi kwetanki emva kokuba umzantsi womququ uzinzisiwe ngokufunxwa.
Ukuqwalasela ukuba i-straws inokwandiswa kwe-3-6%, kubalulekile ukuqinisekisa ubude emva kovavanyo lokuhambelana, kwaye ngokuqinisekileyo uyilo lwe-bevel cut straws lunokunceda kancinci.
Ngamaqhosha afanelekileyo, ivalve ekhethiweyo inokuhambisa iimpawu ze-aerosol kumthengi.Njengeskimu sephakheji yemveliso enzima, idinga ukuhambelana kunye novavanyo lozinzo ukuyila imveliso emangalisayo!
