Kugwiritsa ntchito kwambiri chingwe cha polyethylene fiber

Ngati tikufuna kudziwa kugwiritsa ntchito polyethylene ya polima, choyamba tiyenera kudziwa zomwe zili ndi ubwino wake, zomwe zingapangitse kuti zigwiritsidwe ntchito kwambiri komanso zikhale ndi ntchito zamphamvu kwambiri.
Chingwe cha polyethylene ndi ulusi wapamwamba kwambiri, ndipo Dinima, Netherlands, ndi nthumwi pakali pano.Mosakayikira, mphamvu ya polyethylene yopangidwa ndi mamolekyu apamwamba kwambiri yaku China ikadali yotsika ndi 10% kuposa iyo, koma ili ndi mwayi pakuchita mtengo komanso kuchuluka kwa malonda.Chifukwa kusiyana kwamphamvu kwa 10% kumatha kukonzedwa ndikuwonjezera pang'ono m'mimba mwake.Komabe, makampani ndi mabungwe apanyumba a polymer R&D akutukuka nthawi zonse, ndipo mphamvu zawo zikuyenda bwino nthawi zonse, ndipo azipitilira mayiko akunja.Mpikisano wokhawo ungapangitse ogulitsa zinthu zopangira kuwongolera nthawi zonse.
Chiŵerengero cha polyethylene ndi madzi ndi 0,97: 1, yomwe imatha kuyandama pamwamba pa madzi, ndi elongation ya 4% yokha ndi malo osungunuka a 150. Ndikofunika kukhala ndi kukana kwa UV ndi asidi ndi alkali kukana.
Makhalidwewa amatha kusonyeza kuti angagwiritsidwe ntchito m'madera ena okhala ndi asidi amphamvu ndi zowonongeka za alkali monga kuwala kwa dzuwa, madzi a m'nyanja, ndi zina zotero. komanso kuwala.Ngati mphamvu yomweyi ikufunika, kutalika kwa chingwe cha polyethylene chokhala ndi ma molekyulu apamwamba chikhoza kukhala chaching'ono, ndipo kulemera kwake kumakhala kopepuka kangapo, kotero n'kosavuta kugwira ntchito komanso koyenera kugwiritsidwa ntchito m'madera ofunika monga zombo zazikulu ndi zombo zankhondo.Mwachitsanzo, nayiloni ndi 72mm * 220, ndi mphamvu ya matani 102 ndi kulemera kwa 702KG.Ngati tifunika kufika pa mlingo wa matani 102, tiyenera kusankha awiri a 44mm kusankha polyethylene mkulu-maselo, ndi kulemera kwa 220m ndi 215KG yekha.Poyerekeza, tikhoza kuona bwino ubwino waukulu wa chingwe polymer polyethylene!
Zogwiritsidwa ntchito,
Choyamba, ulusi wa polypropylene, poliyesitala, nayiloni ndi zida zina zitha kusinthidwa mwamphamvu komwe zimagwiritsidwa ntchito, monga mizere yokhotakhota, zingwe zokokera, zingwe zazikulu kwambiri za zombo ndi zombo zankhondo.
Kachiwiri, sinthani zingwe zamawaya zachitsulo, monga zingwe zolumikizira magalimoto, zingwe zokokera magetsi ndi maukonde a zaulimi ndi usodzi, zomwe zitha kugwiritsidwa ntchito.
Pambuyo pake, ndikufuna kuwunikira mphamvu zake, kupepuka, asidi ndi alkali kukana ndi kukalamba, kuti atsimikizire kuti adzakhala ndi udindo waukulu m'madera awa m'tsogolomu.
M'tsogolomu, kugwiritsa ntchito polymer polyethylene kudzakhala malo apamwamba, ndipo anthu sadzasankha zingwe wamba zolemera komanso zotsika mphamvu.Ndi mpikisano pakati pa ogulitsa zinthu zopangira, mtengo wazinthu zopangira udzatsika, zomwe zidzakhala pafupi ndi anthu, ndipo zingwe za polymer polyethylene zidzakhala zinthu zambiri!
