Yadda za a zabi madaidaicin bawul don aerosol?(kimiyya)
A cewar kungiyar masu kera jiragen sama na Biritaniya (BAMA), a yau akwai sama da kayayyakin aerosol guda 200 da ake amfani da su a cikin sirri, gida, masana'antu, aikin gona, gini, wuta, aminci, likitanci da sauran fannoni.
Aerosol bawul ya dubi maras muhimmanci, amma dangane da dukan aerosol samfurin ne mafi muhimmanci, ba kawai alaka da hatimi na samfurin, amma kuma alaka da ejection sakamako, ba shakka, kuma alaka da kwanciyar hankali na dukan aerosol samfurin.Sabili da haka, yadda za a zabi bawul ɗin da ya dace yana da hankali a cikin ci gaban samfuran aerosol.
Kashi casa'in na bawuloli da ake amfani da su a Arewacin Amurka ana kera su ta Percision, Seaquist da Summit, tare da sauran Newman-Green,Bespak, Beardg, Emson, Riker da Coster ke kera su.Seaquist morphed a cikin Aptar Group, wanda ya samu Emson a 1999. Shahararrun masu kaya a kasuwa kuma sun hada da Lindal, Mitani, da dai sauransu. Kuma cikin gida bawul yafi fito daga Amurka, daidaici, cimB da sauran masana'antun.
Idan daga nau'in bawul, aerosol ya kasu kashi biyu: daya da biyu.Babban tsarin aerosol na yuan ɗaya ya haɗa da: tanki, bawul, murfin waje, maɓallin turawa, wakili mai tsini, jikin kayan.Babban sakamakon binaryar aerosol sun haɗa da: tanki, bawul, jakar aluminium multilayer, murfin waje, maɓallin turawa, jikin kayan, iskar gas.
Valve yawanci ya haɗa da: kofin rufewa, gasket na waje, gasket na ciki, tushe, bazara, ɗakin bawul, bambaro da sauran sassa bakwai, la'akari da kayan daban-daban, girma da tsari da sauran dalilai, ka'idar bawul na iya gabatar da dubun biliyoyin canje-canje daban-daban.
Saboda haka, yadda za a zabi madaidaicin bawul yana buƙatar la'akari da waɗannan abubuwan:
Na farko: bawul ɗin dala ɗaya ko bawul ɗin binary?
A cikin cakuda kayan aiki da wakili na aikin, ya kamata a yi la'akari da dacewa da tsarin kayan aiki.Lokacin da aka fesa ma'auni da abun ciki a lokaci guda, yana da sauƙi don samar da cewa an fesa ma'auni, kuma jikin kayan har yanzu ya kasance, wanda ke rinjayar kwarewar mabukaci.Ba za a iya amfani da digiri 360 ba, za a iya amfani da shi kawai a gaba ko juye.Wakilin parabolic mai canzawa (propylene butane ko dimethyl ether), matsa lamba zai karu da geometrically tare da haɓakar zafin jiki, na kayan haɗari ne, sufuri da yanayin ajiya suna da takamaiman buƙatu.
Ko da kuwa farashi, bawuloli na binary suna da fa'idodi da yawa: misali:
Abubuwan da ke ciki ba su tuntuɓar tankin aerosol kai tsaye, suna samar da kariya ga jikin kayan;
Fitar da duk-zagaye, daidaita da yanayin amfani iri-iri;
Bawul bawul jakar kafin cika, kuma za a iya haskakawa ta cobalt 60 disinfection, da dabara iya rage preservatives, rage allergenic tushen;
matsa lamba na yau da kullun a cikin tanki, bargawar fitarwa, ragowar kayan jiki mara nauyi;
Tare da matsa lamba iska ko nitrogen, matsa lamba ya kusan m yayin da yawan zafin jiki ya karu, kuma buƙatun sufuri da ajiya suna da ƙananan ƙananan
Na biyu: zabi na sealing kofin kayan?
Kofuna na ƙarfe yawanci kauri ne 0.27mm kuma kofuna na aluminum suna da kauri 0.42mm.Aikace-aikacen kulawa na sirri sau da yawa suna amfani da kofuna na aluminum, waɗanda suka fi kwanciyar hankali da ƙarancin lalacewa.Girman kwanciyar hankali na kofin ƙarfe ya fi kyau, kuma ba shi da sauƙi a shafe shi ta hanyar tanki ko tsarin rufewa;
Na uku: kayan gasket
Gaskets yawanci ana raba gaskets na ciki da gaskets na waje, kayan sun bambanta, galibi: butyl, chloroprene, butyl, chloroprene, nitrile, chloroprene, polyurethane da sauransu.Rushewar gas ɗin zai shafi dacewa da ƙarar gasket, wani lokacin yana haifar da zubewa.Idan gasket ɗin ya faɗaɗa wuce gona da iri, ba za a iya fallasa ramin bawul ɗin gas ɗin ba lokacin da aka danna bututun ƙarfe, wanda zai shafi ingancin allurar.Bayan gwaje-gwaje akai-akai, an gwada zinare tare da cakuda 75% ethanol da 25% isopentane, kuma mafi kyawun zaɓi shine ingantaccen robar NEOPRENE da BUNA.
Na hudu: budewar kara
Girman gama gari sune 0.35, 0.4, 0.46, 0.51, 0.61mm, kuma adadin ramukan kara yana ɗaya daga cikin abubuwan da ke tabbatar da ƙimar gushing.Hakanan ana samun adadin ramukan kara a cikin jerin daban-daban, tare da 1,2,4,6 har ma da ramuka 8.
Na biyar: kusa da ramin bawul
Ramin gefen lokaci na iskar gas yana kan jikin ɗakin bawul, kuma yana cikin ciki bayan an kulle bawul ɗin.Ana amfani da shi musamman don haɓaka tasirin atomization, haɓaka kwanciyar hankali na fitar da abun ciki na wasu samfuran foda, da haɓaka fitar da samfuran ɗanko.Akwai a cikin ƙirar rami ɗaya da biyu.
Lamba shida: Tsawon bambaro
A cikin saitin farko na iya dogara ne akan tsawon bawul = jimlar tsayin kwalba - saita ƙimar.Tsawon bawul na ƙarshe ya kamata ya kasance a ƙasan 1/3 na Semi-da'irar a kasan tanki bayan an daidaita kasan bambaro ta hanyar jiƙa.
Idan akai la'akari da cewa bambaro yana da haɓakar 3-6%, yana da mahimmanci don tabbatar da tsayin bayan gwajin dacewa, kuma ba shakka ƙirar yanke bambaro na iya taimakawa kaɗan.
Tare da maɓallan da suka dace, bawul ɗin da aka zaɓa zai iya sadar da halayen aerosol ga mabukaci.A matsayin tsarin kunshin don samfur mai rikitarwa, yana buƙatar dacewa da gwajin kwanciyar hankali don tsara samfur mai ban mamaki!
