Kuwonjezera mikanda yagalasi yopanda kanthu kuzinthu za rabara kungayambitse ubwino wambiri:
1, Kuchepetsa thupi
Zopangira mphira komanso kumayendedwe opepuka, okhazikika, makamaka kugwiritsa ntchito kokhwima kwa mphira zazing'ono zazing'ono, kuchokera pakachulukidwe wamba wa 1.15g/cm³ kapena kupitilira apo, onjezani magawo 5-8 a ma microbeads, ochepetsedwa kukhala 1.0g/cm³ (omwe amadziwika kuti " zoyandama pamadzi”), pali mlingo wina wa R & D kuthekera kwa makasitomala powonjezera ma microbeads adzakhala kachulukidwe 0.9 kapena 0.85g/cm³, kuchepetsa kwambiri kachulukidwe mphira, nsapato ndi zinthu zofanana pamaso kuchepetsa kulemera. pafupifupi 20% kapena kuposa.Pakalipano, makasitomala ena omwe ali ndi luso lina la R & D apanga kachulukidwe 0.9 kapena 0.85g/cm³ powonjezera ma microbeads, omwe amachepetsa kwambiri kachulukidwe ka mphira, ndipo kulemera kwa nsapato kumachepetsedwa ndi 20% pansi pa zofanana. monga kale.
2, Kuteteza kutentha
Kapangidwe kachipangizo kakang'ono kagalasi kopanda magalasi kumapangitsa kuti mikandayo ikhale yotsika kwambiri, chifukwa chodzaza mafuta otsika omwe amawonjezeredwa pamtengo wa rabara amatha kusewera bwino kwambiri, monga pamapaipi opangira matenthedwe, matabwa opaka kutentha ndi zinthu zina zomwe zimagwiritsidwa ntchito. .
3, Mayamwidwe amawu ndi kuchepetsa phokoso
Mkati dzenje galasi mikanda ndi woonda mpweya, mafunde phokoso mu gawo ili adzakhala wofooka, mu kuchuluka kwa Kuwonjezera kuimba zotsatira zabwino kwambiri mayamwidwe phokoso ndi kuchepetsa phokoso.
4, Kukhazikika kwabwino kwazithunzi
Mikanda yoyambira ndi galasi yokhala ndi coefficient yocheperako yakukulira kwamafuta, kukhazikika kwapang'onopang'ono ikagwidwa ndi kugwedezeka kwamafuta, kuwonjezeredwa kuzinthu zamphira kumapangitsa kuti chinthucho chikhale chokhazikika bwino.

Malangizo ogwiritsira ntchito pokonza:
1, zida zopangira mphira nthawi zambiri zimakhala zoyenga zowongoka, zotsegulira, zopopera imodzi, etc., chifukwa mikanda ndi khoma lazinthu zamagalasi ndi tinthu tating'onoting'ono tating'onoting'ono, mu gawo la mphamvu yakumeta ubweya wamakina idzasweka pang'ono, mikanda idzatayika. ntchito yake yapadera pambuyo wosweka.
2, mikanda yagalasi yopanda kanthu imakhala ndi mitundu yosiyanasiyana ndi magawo ofananira, malinga ndi zida zosiyanasiyana ndi zofunikira zopangira kusankha mikanda yoyenera ndikofunikira kwambiri, St. Leite amalimbikitsa kugwiritsa ntchito HL38, HL42, HL50, HS38, HS42 muzinthu zamphira.
3, ikagwiritsidwa ntchito mu makina oyenga, pali rotor pa shear wa zinthu za mphira, mikanda singapewedwe ndi mphamvu yakumeta ubweya, momwe mungathere kuchepetsa nthawi ya mikanda pakuyenga, tikulimbikitsidwa kuwonjezera kuyenga mochedwa kuonetsetsa kuti mikanda anawonjezera kuyenga 3-5min akhoza kumwazikana uniformly;mu makina oyenga, katayanidwe wodzigudubuza ndi nthawi yoyenga ya kuphwanya mikanda ali ndi mphamvu yaikulu, tikulimbikitsidwa kuti wodzigudubuza katayanitsidwe> 2mm, kuyenga nthawi sayenera kukhala yaitali;Onse kukameta ubweya wa mphamvu single wononga extruder ndi yaing'ono, kunena, mmene microbeads ndi yaing'ono, tikulimbikitsidwa kuonjezera extrusion kutentha ndi 5 ℃, kuchepetsa mamasukidwe akayendedwe a zinthu ndi yabwino kwa akamaumba extrusion, kuchepetsa microbeads. wosweka.
