Kuwonjezera mikanda yagalasi yopanda kanthu kuzinthu za rabara kungayambitse ubwino wambiri:
1, Kuchepetsa thupi
Zopangira mphira komanso kumayendedwe opepuka, okhazikika, makamaka kugwiritsa ntchito mikanda yaying'ono ya mphira, kuchokera pakachulukidwe wamba wa 1.15g/cm³ kapena kupitilira apo, onjezerani magawo 5-8 a ma microbeads, otsika mpaka 1.0g/cm³ (omwe amadziwika kuti "kuyandama pamadzi"), pali kuchuluka kwamakasitomala ndi R & D cap.9 ngakhale 0.85g/cm³, kuchepetsa kwambiri kachulukidwe mphira, nsapato ndi mkhalidwe womwewo pamaso kuchepetsa kulemera kwa 20% kapena choncho. 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 pafupifupi 20% pansi pazimenezi kale.
2, Kuteteza kutentha
Maonekedwe opanda pake a mikanda yagalasi yopanda kanthu imapangitsa kuti mikandayo ikhale yotsika kwambiri, chifukwa chodzaza mafuta otsika omwe amawonjezedwa pamtengo wa raba amatha kusewera bwino kwambiri, monga pamapadi otsekemera, matabwa otenthetsera matenthedwe 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 wandiweyani, chotsegulira, cholumikizira chimodzi, 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 idzataya magwiridwe antchito ake atasweka.
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 pakupanga mphira.
3, pamene ntchito mu makina kuyenga, pali rotor pa mphira zinthu kukameta ubweya, mikanda sangathe kupewedwa ndi kukameta ubweya mphamvu, kotero ngati n'kotheka kuchepetsa nthawi ya mikanda mu kuyenga, tikulimbikitsidwa kuwonjezera mu kuyenga mochedwa kuonetsetsa kuti mikanda anawonjezera kuyenga 3-5min akhoza omwazika uniformly; mu makina oyenga, katayanidwe ka wodzigudubuza ndi nthawi yoyenga ya kuphwanya mikanda zimakhudza kwambiri, ndi bwino kuti wodzigudubuza katayanitsidwe> 2mm, kuyenga nthawi sayenera kukhala yaitali; Onse kukameta ubweya mphamvu ya single wononga extruder ndi yaing'ono, tikulankhula, zotsatira za microbeads ndi yaing'ono, tikulimbikitsidwa kuonjezera extrusion kutentha ndi 5 ℃, kuchepetsa mamasukidwe akayendedwe a zinthu ndi yabwino kwa extrusion akamaumba, kuchepetsa microbeads wosweka.
