U ka khetha valve e nepahetseng joang bakeng sa aerosol?(saense)
Ho ea ka British Aerosol Manufacturers Association (BAMA), kajeno ho na le lihlahisoa tse fetang 200 tsa aerosol tse sebelisoang libakeng tsa botho, tsa lehae, tsa indasteri, tsa temo, tsa kaho, tsa mollo, tsa tšireletso, tsa bongaka le tse ling.
Valve ea aerosol e shebahala e se na thuso, empa e amanang le sehlahisoa sa aerosol kaofela ke ntho ea bohlokoa ka ho fetisisa, eseng feela e amanang le ho tiisoa ha sehlahisoa, empa hape e amana le phello ea ejection, ha e le hantle, hape e amana le botsitso ba sehlahisoa sohle sa aerosol.Ka hona, mokhoa oa ho khetha valve e nepahetseng e bohlokoa ho ela hloko nts'etsopele ea lihlahisoa tsa aerosol.
Liperesente tse mashome a robong tsa li-valve tse sebelisoang Amerika Leboea li entsoe ke Percision, Seaquist le Summit, ha tse ling kaofela li entsoe ke Newman-Green, Bespak, Beardg, Emson, Riker le Coster.Seaquist morphed into Aptar Group, e ileng ea reka Emson ka 1999. Barekisi ba tsebahalang 'marakeng ba kenyelletsa Lindal, Mitani, joalo-joalo. 'Me valve ea lapeng e tsoa United States, precision, cimB le bahlahisi ba bang.
Haeba ho tsoa sehlopheng sa li-valve, aerosol e arotsoe haholo ka mekhahlelo e 'meli: e le' ngoe le tse peli.Sebopeho se seholo sa yuan aerosol se kenyelletsa: tanka, valve, sekoaelo sa ka ntle, konopo ea push, moemeli oa projectile, 'mele oa thepa.Liphello tse ka sehloohong tsa aerosol ea binary li kenyelletsa: tanka, valve, mokotla oa aluminium oa multilayer, sekoahelo sa ka ntle, konopo ea push, 'mele oa thepa, khase e hatelitsoeng.
Valve hangata e kenyelletsa: senoelo sa ho tiisa, gasket ea ka ntle, gasket e ka hare, kutu, selemo, kamore ea valve, lehlaka le likarolo tse ling tse supileng, ho nahanela lisebelisoa tse fapaneng, boholo le sebopeho le lintlha tse ling, khopolo ea valve e ka hlahisa mashome a limilione tse likete. liphetoho tse fapaneng.
Ka hona, mokhoa oa ho khetha valve e nepahetseng o hloka ho nahana ka lintlha tse latelang:
Ea pele: valve ea dollar e le 'ngoe kapa valve ea binary?
Ka motsoako oa thepa le moemeli oa projectile, ho lumellana ha mokhoa oa thepa ho lokela ho nkoa.Ha moemeli oa projectile le litaba li fafatsoa ka nako e le 'ngoe, ho bonolo ho hlahisa hore moemeli oa projectile o fafalitsoe,' me 'mele oa thepa o ntse o le teng, o amang phihlelo ea bareki.Ha e khone ho sebelisoa likhato tse 360, e ka sebelisoa feela ka pele kapa ka holimo.Volatile parabolic agent (propylene butane kapa dimethyl ether), khatello e tla eketseha geometrically ka ho eketseha ha mocheso, ke oa thepa e kotsi, maemo a lipalangoang le a polokelo a na le litlhoko tse thata.
Ho sa tsotelehe litšenyehelo, li-valve tsa binary li na le melemo e mengata: mohlala:
Lintho tse ka hare ha li kopane ka ho toba le tanka ea aerosol, ho etsa tšireletso ho 'mele oa thepa;
Ejection ka hohle-hohle, ikamahanya le maemo a fapaneng a tšebeliso;
Mokotla oa vacuum valve pele o tlatsa, o ka boela oa khabisoa ke cobalt 60 disinfection, foromo e ka fokotsa li-preservatives, ea fokotsa mohloli oa allergenic;
Khatello e sa khaotseng ka tanka, ejection e tsitsitseng, masala a 'mele a tlaase;
Ka moea o hatelitsoeng kapa naetrojene, khatello e batla e sa fetohe ha mocheso o ntse o eketseha, 'me litlhoko tsa lipalangoang le polokelo li batla li le tlase.
Ea bobeli: khetho ea lisebelisoa tsa senoelo sa ho tiisa?
Likopi tsa tšepe hangata li botenya ba 0.27mm mme likopi tsa aluminium ke 0.42mm botenya.Likopo tsa tlhokomelo ea botho hangata li sebelisa linoelo tsa aluminium, tse tsitsitseng haholoanyane le tse sa senyeheng habonolo.Botsitso ba boholo ba senoelo sa tšepe bo molemo, 'me ha ho bonolo ho angoa ke mokhoa oa ho tiisa tanka kapa senoelo;
Ea boraro: thepa ea gasket
Hangata li-gaskets li arotsoe ka li-gaskets tse ka hare le li-gaskets tse ka ntle, lisebelisoa li fapane, haholo-holo: butyl, chloroprene, butyl, chloroprene, nitrile, chloroprene, polyurethane joalo-joalo.Gasket shrinkage e tla ama stem gasket fit, ka linako tse ling e lebisang ho lutla.Haeba gasket e atoloha ka mokhoa o feteletseng, lesoba la "valve stem" la gasket le ke ke la pepeseha ha nozzle e hatelloa, e tla ama katleho ea ente.Ka mor'a liteko tse pheta-phetoang, khauta e ile ea lekoa ka motsoako oa 75% ethanol le 25% isopentane, 'me khetho e ntle ka ho fetisisa e ne e le rabara e batlang e tsitsitse ea NEOPRENE le BUNA.
Ea bone: lesoba la kutu
Boholo bo tloaelehileng ke 0.35, 0.4, 0.46, 0.51, 0.61mm, 'me palo ea likoti tsa stem ke e' ngoe ea lintlha tse khethollang sekhahla sa ho phalla.Palo ea likoti tsa stem e fumaneha hape ka lihlopha tse fapaneng, tse nang le 1,2,4,6 esita le likoti tse 8.
Ea bohlano: ka thōko ho lesoba la valve
Lesoba la lehlakore la khase le teng 'meleng oa kamore ea li-valve,' me le fumaneha ka hare ka mor'a hore valve e tiisitsoe.E sebelisoa haholo-holo ho eketsa phello ea atomization, ho eketsa botsitso ba lihlahisoa tsa lihlahisoa tse ling tsa phofo, le ho eketsa tlhahiso ea lihlahisoa tse phahameng tsa viscosity.E fumaneha ka meralo ea lesoba le le leng le habeli.
Palo ea botšelela: Bolelele ba joang
Sebakeng sa pele se ka ipapisa le bolelele ba valve = bophahamo bo felletseng ba nkho - boleng bo behiloeng.Bolelele ba valve ea ho qetela bo lokela ho ba ka tlase ho 1/3 ea halofo ea selikalikoe ka tlase ho tanka ka mor'a hore botlaaseng ba lehlaka bo tsitse ka ho koloba.
Ha ho nahanoa hore litlhaka li na le katoloso ea 3-6%, ho bohlokoa ho netefatsa bolelele ka mor'a tlhahlobo ea ho lumellana, 'me ho hlakile hore moralo oa litlhaka tsa bevel cut o ka thusa hanyane.
Ka li-buttons tse loketseng, valve e khethiloeng e ka fana ka litšobotsi tsa aerosol ho bareki.E le morero oa sephutheloana bakeng sa sehlahisoa se rarahaneng, se hloka tlhahlobo ea ho lumellana le botsitso ho theha sehlahisoa se tsotehang!
