Kusanthula kwaubwino kwa mbale zophimbira za pepala pa mbale zophikidwa zomwe zimatha kuwonongeka
Zipangizo zotayidwa zotayidwa kuyambira mu 1984 ku China koyamba, polystyrene (yomwe ndi chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga zinthu zotayidwa ...

Popeza polystyrene siiwonongeka, ndi yovuta kuigwiritsanso ntchito ndi zina zotero, zomwe zimapangitsa kuti ntchito yokonza zinthu ikhale yovuta kwambiri. Pambuyo pa zaka zambiri zogwira ntchito mwakhama, ukadaulo wopanga, ukadaulo ndi zida zotayira zinthu zamkati ndi chakudya ndi zakumwa zapangidwa mwachangu mdziko lathu. Mitundu yonse ya mbale zophikira zophikidwa ndi zotentha monga chakudya chozizira komanso chotentha monga bokosi la chakudya chofulumira. mbale, mbale, mbale zazikulu kwambiri zapangidwa: Zakudya zambiri, mbale zamasamba. Zakudya zaposachedwa. etc. masitolo akuluakulu, omwe akuchita bwino, akwanitsa kukwaniritsa bwino zizolowezi zaku China zodyera, akhoza kuvala supu yotentha ndi mafuta ndi madzi osatulutsa madzi.

Kuyambira pamenepo, makampani opanga mapepala okhala ndi mphamvu zoteteza chilengedwe ku China adayamba kukula mofulumira mpaka kumapeto kwa zaka za m'ma 1990. Pakadali pano, mapangidwe a mapepala okhala ndi zinthu zachilengedwe zachilengedwe!

A, mbale zophikira zowononga za pulp molding
Ndi udzu wa tirigu, nzimbe, bango, udzu ndi zomera zina za pachaka za herbacous fber zamkati kudzera mu kuphwanya zamkati, grouting (kapena kuyamwa, kusokoneza), kupanga, kupanga (kapena kupanga) kudula, kusankha, kupha tizilombo toyambitsa matenda, kulongedza, ndi zina zotero, Zipangizo zomwe zimagwiritsidwa ntchito zimabwezerezedwanso ndi kubwezeretsedwanso, ndipo palibe madzi akuda kapena madzi otayira omwe amapangidwa pogwiritsa ntchito njira yopukutira thupi.

Ubwino wa mbale zopangira pulp molding:
(1) Zinthu zopangira ndi tirigu wotayika kapena tirigu wongowonjezedwanso, bango, udzu, nsungwi, nzimbe, kanjedza ndi ulusi wina wa udzu. Magwero ake ndi ambiri, mtengo wake ndi wotsika, ndipo matabwa sagwiritsidwa ntchito.
(2) Palibe madzi otayira omwe amapangidwa kapena kutulutsidwa panthawi yopanga, Zidebe zosungira zachilengedwe kuchokera ku chilengedwe
(3) Chogulitsachi sichilowa madzi ndipo sichimawola mafuta
(4) Mu ndondomeko yogwiritsira ntchito, ikhoza kuzizira, kuzizira, kutentha kwa uvuni wa microwave, ikhoza kuphika madigiri 220
(5) Chogulitsacho chikhoza kuonongeka kwathunthu mkati mwa masiku 45-90, ndipo chikhoza kupangidwa manyowa kunyumba. Pambuyo powonongeka, chinthu chachikulu ndi zinthu zachilengedwe zomwe sizipanga zinyalala kapena kuipitsa.
(6) Monga chidebe cholongedza, chili ndi mawonekedwe a bufering, compresive resistance komanso shock-resistant zomwe zimatha kuteteza bwino zinthu zomwe zalongedza.
(7) Kuyika zinthu zamagetsi sikupanga magetsi osasinthasintha
