Kuwonjezera mikanda yagalasi yopanda kanthu ku zinthu za rabara kungakubweretsereni zabwino zambiri:
1, Kuchepetsa thupi
Zogulitsa za mphira zimapitanso patsogolo pang'onopang'ono komanso molimba, makamaka kugwiritsa ntchito bwino ma microbeads, kuchokera ku kuchuluka kwa 1.15g/cm³ kapena kuposerapo, kuwonjezera magawo 5-8 a microbeads, kuchepetsedwa kufika pa 1.0g/cm³ (komwe kumadziwika kuti "kuyandama pamadzi"), pali kuchuluka kwina kwa R & D kwa makasitomala powonjezera microbeads kukhala kachulukidwe ka 0.9 kapena 0.85g/cm³, zomwe zimachepetsa kwambiri kuchuluka kwa mphira, nsapato ndi momwemo musanachepetse kulemera kwa 20% kapena kuposerapo. Pakadali pano, makasitomala ena omwe ali ndi luso linalake la R & D adzapanga kuchuluka kwa 0.9 kapena 0.85g/cm³ powonjezera microbeads, zomwe zimachepetsa kwambiri kuchuluka kwa mphira, ndipo kulemera kwa nsapato kudzachepetsedwa ndi pafupifupi 20% pansi pa mkhalidwe womwewo monga kale.
2, Kutentha kutchinjiriza
Kapangidwe ka mikanda yopanda kanthu yagalasi kamapangitsa mikanda kukhala ndi kutentha kochepa, chifukwa chodzaza chotenthetsera chochepa chomwe chimawonjezeredwa ku rabara chingakhale ndi mphamvu yabwino kwambiri yotetezera kutentha, monga ma pads otetezera kutentha, ma board otetezera kutentha ndi zinthu zina zomwe zimagwiritsidwa ntchito.
3, Kuchepetsa phokoso ndi kuyamwa kwa mawu
Mkati mwa mikanda yopanda kanthu yagalasi muli mpweya woonda, mafunde a phokoso m'gawoli adzafooka, kuwonjezera pa kuchuluka kwake kuti azitha kuyamwa bwino mawu komanso kuchepetsa phokoso.
4, kukhazikika kwabwino kokhala ndi mawonekedwe
Zinthu zoyambira za mikanda ndi galasi yokhala ndi kutentha kochepa, kukhazikika bwino muyeso ikakhudzidwa ndi kutentha, kuwonjezeredwa ku zinthu za rabara kudzapatsa chinthucho kukhazikika bwino muyeso.

Malangizo ogwiritsira ntchito pokonza:
1, zipangizo zopangira mphira nthawi zambiri zimakhala zokhuthala kwambiri, zotsegulira, zotulutsira zolemera, ndi zina zotero, chifukwa mikanda ndi galasi, khoma ndi la tinthu tolimba, mphamvu yoduladula idzasweka pang'ono, mikanda idzataya ntchito yake yapadera ikasweka.
2, mikanda yopanda kanthu yagalasi ili ndi mitundu yosiyanasiyana ndi magawo ofanana, malinga ndi zida zosiyanasiyana ndi zofunikira za malonda kuti asankhe zinthu zoyenera za mikanda ndizofunikira kwambiri, St. Leite amalimbikitsa kugwiritsa ntchito HL38, HL42, HL50, HS38, HS42 muzinthu za rabara.
3, ikagwiritsidwa ntchito mu makina oyeretsera, pali chozungulira pa chometera cha rabara, mikanda singapewedwe ndi mphamvu yometera, kotero momwe zingathere kuti muchepetse nthawi ya mikanda mu kuyeretsa, tikukulimbikitsani kuwonjezera kuyeretsa komaliza kuti zitsimikizire kuti mikanda yowonjezeredwa ku kuyeretsa kwa mphindi 3-5 ikhoza kufalikira mofanana; mu makina oyeretsera, mtunda wa roller ndi nthawi yoyeretsera ya kuphwanya mikanda zimakhudza kwambiri, tikukulimbikitsani kuti mtunda wa roller > 2mm, nthawi yoyeretsera siyenera kukhala yayitali kwambiri; Mphamvu yonse yometera ya chometera chimodzi ndi yaying'ono, ponena kuti, mphamvu pa mikanda yaying'ono ndi yaying'ono, tikukulimbikitsani kuwonjezera kutentha kwa extrusion ndi 5 ℃, kuchepetsa kukhuthala kwa zinthuzo kuti zikhale bwino pakuumba extrusion, kuchepetsa mikanda yaying'ono yosweka.
