EPS foam block Chiyambi cha njira yopanga

1.Zinthu

Zazikulu: EPS + Foaming wothandizira + flame retardant (malinga ndi zofunika kasitomala)

2.Njira Yoyambira

A. Kuthira ndi kuchita thovu: ikani zopangira za mikanda yokhala ndi thovu (pentane) mu hopper, ndipo ingodyani mumtanda wodziwikiratu wotulutsa thovu. Panthawi imeneyi, polima particles munali thobvu wothandizila ndi Kufewetsa pansi nthunzi Kutentha, ndi thobvu kutentha ndi za 100 ° C, ndi thovu wothandizila ndi volatilized. Zotsatira zake ndikukula mkati mwa mkanda uliwonse, kupanga maselo ambiri. Ndipo kupanga maselo osagwirizana, pochita izi, mikanda iyenera kukhalabe omwazika komanso omasuka.

B. Kuyanika: Mikanda imawumitsidwa kudzera pa bedi lowumitsira thovu, ndipo kutentha kumayendetsedwa pafupifupi 50 ° C.

C.Curing: Zida zouma zouma zimalowetsedwa mu silo yochiritsira ndi chofanizira chowotcha, ndipo kudzitenthetsa nokha kumakhala pafupifupi maola 6. Nthawi yochiritsa imasinthidwa moyenera malinga ndi kutentha kwakunja. Kubwereranso, mpweya umalowa mkati mwa selo kudzera mu cell membrane, kotero kuti kuthamanga kwa selo kumakhala kofanana ndi kuthamanga kwa kunja. Izi zipangitsa kuti mikanda yatsitsi isanakwane zotanuka.

D. jekeseni akamaumba: The mikanda pre- kuchiritsidwa ndi kutenthedwa ndi nthunzi, ndipo iwo adzakula pambuyo kutenthedwa kupanga kukakamiza. Panthawiyi, polimayo amafewetsa ndikuwonjezeranso, ndikudzaza kusiyana pakati pa mikanda kuti apange chipika chonse kuti apange pulasitiki yopangidwa thovu.

E. Kuzizira ndi kugwetsa: Zimapangidwa ndi vacuum kapena fan

kuziziritsa, ndipo pambuyo kuumba, mphamvu mphamvu ya wothinikizidwa mpweya ntchito kuti mankhwala demould bwino. Pambuyo pa kutulutsidwa, kulemera kwa mbaleyo kumawonetsedwa, ndipo mbaleyo imatha kunyamulidwa ndi forklift kupita kumalo osungiramo mankhwala kapena kutumizidwa mwachindunji kumalo osungiramo katundu ndi lamba wonyamula katundu kuti achiritsidwe.

F.Kukalamba: Pambuyo pa sabata la nthawi yochiritsa, tinthu tating'onoting'ono tating'onoting'ono tambiri tambiri timakhala tokhazikika, ndipo titha kudulidwa molingana ndi kukula komwe kasitomala amafunikira, ndipo kukula kwa mbale yochiritsidwa sikungasinthe.

Kompyuta basi kusintha waya, mkulu kudula molondola

Kudula kwa vibration kwa bolodi ya benzene yokhala ndi luso lodula kwambiri

Mkulu digiri ya zochita zokha ndi mkulu kupanga bwino
