Kapangidwe ka pepala la polyethylene lolemera kwambiri

Polyethylene yolemera kwambiri ya molekyulu (UHMW-PE) ndi chinthu chopangidwa ndi thermoplastic chomwe chimaphatikiza zabwino zonse za pulasitiki. Ndi kukana kukalamba, kukana kugwedezeka, kukana dzimbiri kwa mankhwala, mafuta awoawo, kukana kukalamba kutentha kochepa, kulemera kochepa, kuyamwa mphamvu, kukana kukalamba, kukana malawi, kukana kusinthasintha ndi magwiridwe antchito ena abwino, kugwiritsa ntchito UHMW-PE plate lining power plant, fakitole ya malasha, fakitole ya malasha ya coking; Ore ndi zinthu zina zosungira simenti, fakitole yachitsulo ndi fakitole ya aluminiyamu; Tirigu, chakudya, nkhokwe yamakampani opanga mankhwala, chosungiramo madoko, ndi zina zotero, zimatha kuletsa zinthu zomata, kufulumizitsa liwiro la chakudya, kuthetsa ngozi za douce, kusunga ndalama ndi mtengo wa mfuti yampweya, chogwirira chachikulu cha lining chingapewe kumatirira ufa pamalo ogwirira ndikuchepetsa kuwonongeka kwa makina okweza ndi kutsitsa katundu kupita ku malo ogwirira. Ndi chitukuko cha ukadaulo wopangira pulasitiki, gawo logwiritsira ntchito la UHMW-PE lidzakhala lalikulu.

A, kukana kuvala kwambiri, chifukwa cha kapangidwe kake kapadera ka mamolekyu, kukana kuvala ndikokwera kuposa zinthu zonse zapulasitiki zachitsulo, chitsulo cha kaboni nthawi 6.6, chitsulo chosapanga dzimbiri nthawi 5.5, mkuwa nthawi 27.3, nayiloni nthawi 6, ptfe nthawi 5;

B, kudzipaka bwino, kusakaniza pang'ono, kukana kuyenda pang'ono, kusunga mphamvu;

C, mphamvu yogwira ntchito kwambiri, kulimba bwino, ngakhale kutentha kutsika, chifukwa cha mphamvu yogwira ntchito kwambiri sidzasweka;

D, kukana dzimbiri kwa mankhwala, kukana (kupatula asidi wokhuthala wa sulfuric, asidi wokhuthala wa nitric, mphamvu zochepa zachilengedwe) pafupifupi asidi onse, alkali, ndi mchere;

E, si poizoni, yopanda kukoma, yopanda exudate;

F, mphamvu zamagetsi zabwino, kuyamwa madzi pang'ono kwambiri;

G, kukana bwino kwambiri kupsinjika kwa chilengedwe, kuwirikiza nthawi 200 kuposa polyethylene wamba;

H, kukana kutentha kochepa kwambiri, sikuphwanyika ngakhale pa -180C °.
