Momwe mungasankhire valavu yoyenera ya aerosol?(sayansi)
Malinga ndi British Aerosol Manufacturers Association (BAMA), lero pali zinthu zoposa 200 za aerosol zomwe zimagwiritsidwa ntchito pazinthu zaumwini, nyumba, mafakitale, zaulimi, zomangamanga, moto, chitetezo, zamankhwala ndi zina.
Valavu ya aerosol ikuwoneka ngati yopanda pake, koma yokhudzana ndi mankhwala onse a aerosol ndi chinthu chofunika kwambiri, osati chokhudzana ndi kusindikiza kwa mankhwala, komanso zokhudzana ndi ejection effect, ndithudi, zimagwirizananso ndi kukhazikika kwa mankhwala onse a aerosol.Chifukwa chake, momwe mungasankhire valavu yoyenera ndikofunikira pakupanga zinthu za aerosol.
Ma valve makumi asanu ndi anayi pa zana aliwonse omwe amagwiritsidwa ntchito ku North America amapangidwa ndi Percision, Seaquist ndi Summit, ndipo ena onse amapangidwa ndi Newman-Green, Bespak, Beardg, Emson, Riker ndi Coster.Seaquist morphed mu Aptar Group, yomwe inapeza Emson mu 1999. Odziwika bwino ogulitsa pamsika akuphatikizapo Lindal, Mitani, ndi zina zotero.
Ngati kuchokera ku gulu la vavu, aerosol imagawidwa m'magulu awiri: imodzi ndi ziwiri.Kapangidwe kake kakang'ono ka yuan aerosol kumaphatikizapo: thanki, valavu, chivundikiro chakunja, batani lakukankha, wothandizira projectile, thupi lakuthupi.Zotsatira zazikulu za aerosol ya binary ndi monga: thanki, valavu, chikwama cha aluminiyamu chamitundu yambiri, chivundikiro chakunja, batani lakukankha, thupi lazinthu, mpweya woponderezedwa.
Vavu zambiri zikuphatikizapo: kusindikiza chikho, gasket akunja, gasket mkati, tsinde, kasupe, valavu chipinda, udzu ndi mbali zina zisanu ndi ziwiri, kutenga nkhani zipangizo zosiyanasiyana, kukula ndi kapangidwe ndi zinthu zina, chiphunzitso cha valavu akhoza kupereka makumi mabiliyoni a kusintha kosiyana.
Chifukwa chake, momwe mungasankhire valavu yoyenera muyenera kuganizira izi:
Choyamba: valavu ya dollar imodzi kapena valavu ya binary?
Mu kusakaniza kwa zinthu ndi projectile wothandizira, kugwirizana kwa chilinganizo cha zinthu kuyenera kuganiziridwa.Pamene wothandizira projectile ndi zomwe zili ndi sprayed panthawi imodzimodziyo, zimakhala zosavuta kupanga kuti wothandizira projectile atayidwa, ndipo thupi lakuthupi likadalipo, lomwe limakhudza zomwe ogula akukumana nazo.Sangagwiritsidwe ntchito madigiri 360, angagwiritsidwe ntchito kutsogolo kapena mozondoka.Wosakhazikika parabolic wothandizira (propylene butane kapena dimethyl ether), kupanikizika kumawonjezeka geometrically ndi kuwonjezeka kwa kutentha, ndi wa zinthu zoopsa, mayendedwe ndi kusungirako zinthu zofunika kwambiri.
Mosasamala mtengo, ma valve a binary ali ndi zabwino zambiri: mwachitsanzo:
Zomwe zili mkati sizimalumikizana mwachindunji ndi thanki ya aerosol, kupanga chitetezo ku thupi lazinthu;
Kutulutsa kozungulira konsekonse, kutengera mawonekedwe osiyanasiyana ogwiritsira ntchito;
Thumba la vacuum vavu musanadzaze, limathanso kuyatsidwa ndi cobalt 60 disinfection, chilinganizocho chingachepetse zoteteza, kuchepetsa gwero la allergenic;
Kupanikizika kosalekeza mu thanki, kutulutsa kokhazikika, zotsalira zakuthupi zotsika;
Ndi mpweya woponderezedwa kapena nayitrogeni, kupanikizika kumakhala kosasintha pamene kutentha kumawonjezeka, ndipo zofunikira pamayendedwe ndi kusungirako ndizochepa.
Chachiwiri: kusankha kusindikiza zinthu za chikho?
Makapu achitsulo nthawi zambiri amakhala okhuthala 0.27mm ndipo makapu a aluminiyamu amakhala okhuthala 0.42mm.Ntchito zothandizira anthu nthawi zambiri zimagwiritsa ntchito makapu a aluminiyamu, omwe amakhala okhazikika komanso osachita dzimbiri.Kukhazikika kwa kapu yachitsulo ndikwabwinoko, ndipo sikophweka kukhudzidwa ndi thanki kapena ndondomeko yosindikiza chikho;
Chachitatu: zinthu za gasket
Gaskets nthawi zambiri anawagawa gaskets mkati ndi gaskets kunja, zipangizo zosiyanasiyana, makamaka: butyl, chloroprene, butyl, chloroprene, nitrile, chloroprene, polyurethane ndi zina zotero.Kutsika kwa gasket kumakhudza kukwanira kwa gasket, nthawi zina kumabweretsa kutayikira.Ngati gasket ikuchulukirachulukira, dzenje la valavu la gasket silingawululidwe pomwe mphunoyo ikanikizidwa, zomwe zingakhudze jekeseni.Pambuyo poyesedwa mobwerezabwereza, golidi anayesedwa ndi 75% ethanol ndi 25% isopentane, ndipo chisankho chabwino chinali mphira wokhazikika wa NEOPRENE ndi BUNA.
Chachinayi: pobowola tsinde
Miyeso yodziwika bwino ndi 0.35, 0.4, 0.46, 0.51, 0.61mm, ndipo kuchuluka kwa mabowo ndi chimodzi mwazomwe zimatsimikizira kuchuluka kwa kuthamanga.Kuchuluka kwa mabowo a tsinde kumapezekanso m'magulu osiyanasiyana, okhala ndi 1,2,4,6 komanso mabowo 8.
Chachisanu: pambali pa dzenje la valve
Bowo la mbali ya mpweya lili pa thupi la chipinda cha valve, ndipo limapezeka mkati pambuyo posindikizidwa valavu.Izo makamaka ntchito kuonjezera zotsatira atomization, kuonjezera bata okhutira ejection ena mankhwala ufa, ndi kuonjezera ejection mkulu mamasukidwe akayendedwe mankhwala.Zopezeka muzojambula za dzenje limodzi komanso ziwiri.
Nambala 6: Kutalika kwa udzu
Pachiyambi choyamba chikhoza kukhazikitsidwa pa kutalika kwa valve = kutalika kwa mtsuko - mtengo wokhazikitsidwa.Kutalika kwa valve yomaliza kuyenera kukhala pansi pa 1/3 ya theka-bwalo pansi pa thanki pambuyo pokhazikika pansi pa udzu ndikunyowa.
Poganizira kuti udzu uli ndi kufalikira kwa 3-6%, ndikofunikira kutsimikizira kutalika kwake pambuyo poyezetsa kuyanjana, ndipo ndithudi mapangidwe a bevel odulidwa udzu angathandizenso pang'ono.
Ndi mabatani oyenera, valavu yosankhidwa imatha kupereka mawonekedwe a aerosol kwa ogula.Monga dongosolo la phukusi lazinthu zovuta, zimafunikira kuyesedwa koyenera komanso kukhazikika kuti apange chinthu chodabwitsa!
