Saita sigogi na bushewa: Sanya madaidaicin iska ta iska mai dacewa, zazzabi na sama zazzabi da matsi na fesa. Gabaɗaya, zazzabi iska na inlet an sarrafa shi a 150-200 ℃, kuma zazzabi iska an sarrafa shi a 60-80 ℃.
Fesa a cikin tsarin bushewa: emulsiated emulsifion an daure shi zuwa kyakkyawan droplets ta hanyar sprayer, da da sauri yana da kwastomomi don samar da lafiya bushe barbashi barbashi.
Tarin Foda: Ana tattara foda mai bushe da foda mai bushe ta hanyar mai raba kan Cyclone ko matatar jaka. An cire tarin foda na marigayin da aka tattara kuma an cire manyan barbashi ta hanyar allo don tabbatar da daidaiton samfurin.
5. Post-Post da Kaya
Lateitar da aka bushe na marigayi foda yana buƙatar dacewa da tsari don tabbatar da tsayayyen aikinta da kuma ingantaccen ajiyar wuri. Post-Production yafi ya hada da:
Jinshin anti-Cakindu: kara wakilan anti-cinging (kamar Tallum foda, silicon Dioxide) zuwa farfajiya na marigayi foda don hana foda daga agglomatusatus.
Wagagging: Dangane da bukatun abokin ciniki, latex foda yana kunshi a cikin danshi-tabbaci da tabbaci-tabbaci jaka ko ganga. Saurin zafi yana bukatar a sarrafa shi sosai yayin aiwatarwa don hana foda daga danshi.
6. Gudanar da inganci
A yayin aiwatar da samarwa, ana buƙatar ikon sarrafa ingancin ingancin tabbatar da cewa alamun aikin aikin da ke cikin marigayi foda tare da biyan bukatun. Abubuwan sarrafawa masu inganci na yau sun haɗa da:
Rarraba girman barbashi: girman girman barbashi ana gano shi ta hanyar girman yawan adadin ƙimar laser don tabbatar da daidaitaccen samfurin.
Theresion ƙarfi: gwada ƙarfin haɓaka na ƙarshen lateX foda a kan juzu'i daban-daban don tabbatar da aikinta na.
Maimaitawa: Mix lateX foda tare da ruwa don lura da ko ana iya gano shi a hankali kuma an dawo da shi zuwa ga emulsion jihar.
7. Aikace-aikace da taka tsi
Ana amfani da foda latex foda sosai a cikin tuguwar ƙonewa, tala adon, tsarin rufin bango da sauran filayen. Ana buƙatar lura da maki masu zuwa lokacin amfani da:
Yanayin ajiya: LateX foda ya kamata a adana a bushe da kuma sanyi yanayin don guje wa high zazzabi da zafi.
Amfani da kuɗi: Dangane da takamaiman buƙatun aikace-aikacen, ƙara marigayi maris latex mai dacewa don samun mafi kyawun aikin.
Tare da wasu ƙari: Ana amfani da foda ƙarshen latex foda tare da wasu ƙari (kamar sel na ether, mai ƙyalli) don haɓaka aikin kayan.
Ana iya samun nasarar samar da foda na latex foda mai kyau tare da kyakkyawan aiki ana iya samun nasarar samar da nasara. A cikin ainihin samarwa, ya zama dole a daidaita gwargwadon takamaiman yanayin samarwa da kuma buƙatun samfur don tabbatar da ingantaccen ingancin samfurin.
