Wowotcha aliyense amafuna kuti makasitomala awo apindule kwambiri ndi khofi wawo.
Pofuna kutulutsa makhalidwe abwino a khofi wobiriwira wapamwamba kwambiri, okazinga amathera khama kwambiri posankha mbiri yabwino yowotcha.
Ngakhale zonsezi zikugwira ntchito komanso kuwongolera bwino kwabwino, ngati khofiyo idayikidwa molakwika, kasitomala woyipa ndi wotheka.Khofi wowotcha amawonongeka msanga ngati sanapakidwe kuti akhalebe watsopano komanso wabwino.
Wogulayo angataye mwayi wolawa zokometsera zomwezo zomwe zowotchazo zinkachita pokanika.
Kuyika ma valve ochotsa mpweya m'matumba a khofi ndi njira imodzi yabwino kwambiri yowotcha kuti aletse kuwonongeka kwa khofi wowotcha.
Imodzi mwa njira zodziwika bwino komanso zogwira mtima zosungirako zomverera ndi kukhulupirika kwa khofi ndi kugwiritsa ntchito ma valve a degassing.
Pitirizani kuwerenga kuti mudziwe momwe ma valve ochotsera mpweya amagwirira ntchito komanso ngati mungathe kuwagwiritsanso ntchito ndi matumba a khofi.
N'chifukwa chiyani matumba a khofi okhala ndi mavavu ochotsera gasi amachokera kwa owotcha?
Mpweya wa carbon dioxide (CO2) umachulukana kwambiri mkati mwa nyemba za khofi panthawi yokazinga.
Chifukwa cha izi, nyemba ya khofi imakulitsa pafupifupi 40% mpaka 60%, yomwe imakhala ndi mawonekedwe owoneka bwino.
M'zaka za khofi, CO2 yomweyo yomwe idasonkhanitsidwa panthawi yowotcha imatulutsidwa pang'onopang'ono.Kusungidwa kosakwanira kwa khofi wowotcha kumapangitsa kuti CO2 ilowe m'malo ndi mpweya, zomwe zimawononga kukoma kwake.
Kufalikira ndi chithunzi chochititsa chidwi cha kuchuluka kwa mpweya womwe umakhala mkati mwa nyemba za khofi.
Kuthira madzi pa khofi wapansi panthawi yomwe ikufalikira kumapangitsa kuti CO2 itulutsidwe, yomwe imafulumizitsa njira yochotsa.
Payenera kukhala thovu zambiri zowonekera pamene khofi wokazinga waphikidwa kumene.Chifukwa CO2 mwina yasinthidwa ndi mpweya, nyemba zakale zimatha kupanga "chimake" chochepa.
Kuti tithane ndi vutoli, valavu ya njira imodzi yochotsera gasi inali yovomerezeka mu 1960.
Ma valve ochotsa mpweya amathandiza CO2 kutuluka phukusi popanda kulola mpweya kulowa pamene alowetsedwa m'matumba a khofi.
Kuti zinthu ziipireipire, nthawi zina, khofi imatha kusungunuka mwachangu, ndikuwonjezera thumba la khofi.Ma valve ochotsa mpweya amalola mpweya wotsekeka kuthawa, kuteteza thumba kuti lisatuluke.
Mavavu ochotsera gasi ayenera kuikidwa muzotengera za khofi poganizira zinthu zingapo.
Mwachitsanzo, okazinga ayenera kuganizira zowotcha chifukwa zowotcha zakuda zimakonda kutentha kwambiri kuposa zowotcha zopepuka.
Chifukwa chakuti nyemba zawonongeka kwambiri, kuwotcha kwakuda kumafulumizitsa ntchito yochotsa mpweya.Zing'onozing'ono zambiri zimakhalapo, zomwe zimapangitsa kuti CO2 itulutsidwe, ndipo mashuga akhala ndi nthawi yambiri yosintha.
Zowotcha zowala zimasiya nyemba zambiri, zomwe zingatanthauze kuti zimatenga nthawi yayitali kuti degas.
Kuchuluka kwake ndi chinthu china choyenera kuganizira.Wowotcha sadzakhala ndi nkhawa kuti thumba la khofi likutuluka ngati akulongedza tinthu tating'onoting'ono, tating'onoting'ono tomwe timakonda kulawa.
Kuchuluka kwa nyemba m'thumba kumagwirizana mwachindunji ndi kuchuluka kwa CO2 yotulutsidwa.Akulangizidwa kuti owotcha omwe amanyamula matumba a khofi olemera kuposa 1 kg kuti atumizidwe amatengera zotsatira za degassing.
Ma valve ochotsa mpweya: amagwira ntchito bwanji?
M'zaka za m'ma 1960 adatulukira ma valve ochotsa mpweya ndi bizinesi ya ku Italy Goglio.
Iwo adakambirana ndi vuto lalikulu lomwe mabizinesi ambiri a khofi anali nawo ndi degassing, oxidation, ndikusunga mwatsopano.
Mavavu a Degassing asintha pakapita nthawi chifukwa amakhala olimba komanso otsika mtengo.
Masiku ano mavavu ochotsera gasi samangokwanira bwino mkati mwa matumba a khofi, komanso amafunikira pulasitiki yochepera 90%.
Zosefera pamapepala, kapu, chimbale chotanuka, chotchinga cha viscous, mbale ya polyethylene, ndi valavu ya degassing ndizofunikira kwambiri.
Madzi osindikizira amavala mkati mwake, kapena mbali yoyang'ana khofi, ya mphira wa rabara wotsekeredwa mu valavu, kuti asagwedezeke pamwamba pa valavu.
Pamene khofi imatulutsa CO2, kupanikizika kumawonjezeka.Madzi amadzimadzi amasuntha diaphragm pamene kupanikizika kukadutsa pamtunda, zomwe zimapangitsa kuti CO2 yowonjezera ituluke.
Valavu imatsegula kokha pamene kupanikizika mkati mwa thumba la khofi kuli kwakukulu kuposa kukakamiza kunja, kuziyika mophweka.
Kuthekera kwa mavavu a degassing
Owotcha ayenera kuganizira momwe ma valve ochotsera mpweya, omwe nthawi zambiri amaphatikizidwa m'matumba a khofi, adzatayidwa ndi kulongedza.
Makamaka, bioplastics yatchuka ngati njira ina m'malo mwa mapulasitiki opangidwa ndi mafuta.
Bioplastics ili ndi mikhalidwe yofanana ndi mapulasitiki wamba koma imakhala ndi mphamvu yochepa kwambiri ya chilengedwe chifukwa imapangidwa ndi fermenting ma carbohydrates kuchokera kumalo ongowonjezedwanso kuphatikiza nzimbe, chimanga chowuma, ndi chimanga.
Mavavu ochotsera gasi opangidwa ndi zinthu zokometsera zachilengedwezi tsopano ndi osavuta kupeza komanso amtengo wapatali.
Mavavu ochotsera gasi opangidwa ndi zinthu zobwezerezedwanso angathandize owotcha kuti asunge mafuta oyaka, kuchepetsa mphamvu ya kaboni, ndikuwonetsa kuthandizira kwawo kuti asasunthike.
Kuphatikiza apo, amapangitsa kuti makasitomala azitha kutaya zonyamula khofi moyenera komanso momveka bwino.
Makasitomala amatha kugula thumba la khofi lokhazikika pomwe mavavu otulutsa mpweya osasunthika akuphatikizidwa ndi zinthu zobwezerezedwanso kapena zophatikizika, monga pepala la kraft lokhala ndi polylactic acid (PLA) laminate.
Izi zitha kukulitsa kukhulupirika kwamakasitomala omwe alipo omwe angasinthire kukhulupirika kwawo kwa opikisana nawo okonda zachilengedwe kuphatikiza kuwapatsa mwayi wosangalatsa.
Ku CYANPAK, timapereka owotcha khofi mwayi wowonjezera mavavu ochotsera khofi opanda BPA m'matumba awo.
Mavavu athu ndi osinthika, opepuka, komanso okwera mtengo, ndipo atha kugwiritsidwa ntchito ndi zosankha zathu zilizonse zokometsera khofi.
Owotcha amatha kusankha kuchokera kuzinthu zosiyanasiyana zobwezerezedwanso zomwe zimachepetsa zinyalala ndikuthandizira chuma chozungulira, kuphatikiza mapepala a kraft, mapepala ampunga, ndi ma LDPE amitundu yambiri okhala ndi PLA yamkati yochezeka.
Kuphatikiza apo, timapatsa owotcha athu ufulu wakulenga powalola kupanga zikwama zawo za khofi.
Mutha kupeza thandizo kuchokera kwa ogwira ntchito yopanga khofi kuti abwere ndi phukusi loyenera la khofi.
Kuonjezera apo, timapereka matumba a khofi osindikizidwa omwe ali ndi nthawi yochepa yosinthira maola 40 ndi nthawi yotumiza maola 24 pogwiritsa ntchito luso lamakono losindikiza digito.
Kuphatikiza apo, CYANPAK imapereka zinthu zotsika mtengo (MOQs) kwa owotchera ang'onoang'ono omwe akufuna kukhala osinthika pomwe akuwonetsa mtundu wawo komanso kudzipereka kwawo kwa chilengedwe.
