Mafotokozedwe Akatundu
Mphamvu yokoka yowunikira komanso voliyumu yayikulu.Kuchulukana kwa mikanda yagalasi yopanda kanthu ndi pafupifupi gawo limodzi mwa magawo khumi a zodzaza zachikhalidwe.Pambuyo podzaza, imatha kuchepetsa kwambiri kulemera kwazinthu, m'malo mwake ndikusunga ma resin ochulukirapo ndikuchepetsa mtengo wazinthu.
Ndi organic kusinthidwa (lipophilic) pamwamba.Mikanda yagalasi yopanda kanthu imatha kunyowetsedwa ndikubalalitsidwa mosavuta, ndipo imatha kudzazidwa ndi utomoni wambiri wa thermosetting thermoplastic, monga poliyesitala, epoxy resin, polyurethane, ndi zina zambiri.
Kubalalika kwakukulu ndi madzi abwino.Chifukwa mikanda yagalasi yopanda kanthu ndi mipira yaying'ono yozungulira, imakhala ndi madzi abwinoko mu utomoni wamadzimadzi kuposa flake, singano kapena zodzaza zosakhazikika, kotero zimakhala ndi ntchito yabwino yodzaza nkhungu.Chofunika kwambiri, mtundu uwu wa mkanda wawung'ono ndi isotropic, choncho sichidzachititsa kuti pakhale kuwonongeka kosagwirizana m'madera osiyanasiyana chifukwa cha kayendetsedwe kake, kuti zitsimikizire kukhazikika kwa chinthucho ndipo palibe warpage.
Kutenthetsa kutentha, kutsekereza mawu, kutsekereza komanso kuyamwa kwamadzi pang'ono.Mkati mwa mikanda yagalasi yopanda phokoso ndi mpweya wochepa kwambiri, choncho imakhala ndi makhalidwe otsekemera komanso kutentha.Ndiwodzaza bwino kwambiri pakutchinjiriza kutentha kosiyanasiyana komanso zopangira mawu.Makhalidwe otenthetsera matenthedwe amikanda yagalasi yopanda kanthu amatha kugwiritsidwanso ntchito kuteteza zinthu ku mantha amafuta omwe amayamba chifukwa cha kusintha kosinthika pakati pa kutentha mwachangu ndi kuzizira kofulumira.Kukana kwakukulu komanso kuyamwa kwamadzi otsika kumapangitsa kuti azigwiritsidwa ntchito kwambiri pokonza ndi kupanga zida zotchinjiriza chingwe.
Kutsika kwa mayamwidwe amafuta.Tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tambiri timene timayamwa mafuta.Pogwiritsa ntchito, kuchuluka kwa utomoni kumatha kuchepetsedwa kwambiri.Ngakhale pamaziko a kuwonjezereka kwakukulu, kukhuthala sikungawonjezeke kwambiri, zomwe zimathandizira kwambiri kupanga ndi magwiridwe antchito ndikuwongolera magwiridwe antchito.
Mikanda yagalasi yopanda kanthu imagwiritsidwanso ntchito kwambiri pakupanga agate, marble, FRP Bowling mpira ndi zida zina zofananira ndi zokutira zotenthetsera zapamwamba kwambiri, zomwe zimatha kuchepetsa kwambiri kulemera kwazinthu ndikukhala ndi zotsatira zabwino zotchinjiriza.
Mikanda yagalasi yopanda kanthu ndi yabwino kwambiri yodziwitsira zophulika za emulsion, zomwe zimatha kusintha kwambiri kuyambitsa kwa zophulika za emulsion ndikutalikitsa nthawi yosungira.Kuphatikiza apo, mikanda yagalasi yopanda kanthu itha kugwiritsidwanso ntchito muphulusa la atomiki kuti iwonjezere voliyumu, kupititsa patsogolo ntchito yakupera ndikuwongolera kukana kwa acid-base.
