Ubwino wogwiritsa ntchito polyethylene wothira chlorine mu zingwe za pa intaneti

1. Kukweza mulingo waukadaulo wa zinthu za chingwe
Ukadaulo wa CPE uli ndi magwiridwe antchito ambiri, umachepetsa moto bwino komanso umalimbana ndi mafuta, umalimbana ndi kutentha kwambiri, umalimbana ndi ozoni, umalimbana ndi nyengo, komanso umalimbana ndi kusakaniza zinthu. Uli ndi mphamvu yosungira zinthu nthawi yayitali popanda kuwonongeka, zomwe zimapangitsa kuti ukhale chingwe chabwino.
Kutentha kwa CPE komwe kumagwira ntchito kwa nthawi yayitali ndi 90 ℃, ndipo bola ngati njirayo ndi yoyenera, kutentha kwake kwakukulu kogwira ntchito kumatha kufika 105 ℃. Kugwiritsa ntchito CPE kumatha kuwonjezera kuchuluka kwa zingwe za rabara kuchokera pa 65 ℃ kufika pa 75-90 ℃ kapena ngakhale 105 ℃ m'maiko otukuka akunja. Guluu wa CPE wokha ndi woyera ngati chipale chofewa, kotero kaya umagwiritsidwa ntchito ngati chotenthetsera kapena chidebe, ukhoza kupangidwa kukhala zinthu zokongola malinga ndi zosowa za ogwiritsa ntchito. Komabe, zinthu wamba monga rabara wachilengedwe, rabara wa styrene butadiene, rabara wa chloroprene, ndi rabara wa nitrile zimakhala zovuta kupanga mitundu yoyera kapena yokongola chifukwa cha chikasu chawo. Kuphatikiza apo, rabara wa chloroprene womwe umagwiritsidwa ntchito kwambiri ndi rabara wa polyethylene wa chlorosulfonated zimakhala zovuta kuthetsa mavuto monga poizoni wa monomer ndi solvent, volatilization, ndi zina zotero panthawi yopanga. Posungira, mayendedwe, ndi kupanga zingwe, mavuto monga kutentha ndi kukhazikika kwa roller nthawi zambiri amapezeka. Kwa CPE, mavuto awa omwe amayambitsa mutu sapezeka. Mfundo ina yofunika kuiganizira ndi yakuti chlorination ikagwiritsidwa ntchito poteteza mphamvu yamagetsi ochepa, siingaipitse maziko a mkuwa, zomwe mosakayikira zimakweza luso la chingwe.
2. Kusinthasintha kwa njira zambiri, mtengo wotsika, komanso phindu
Pambuyo potulutsidwa ndi chotulutsira rabara, rabara yosakanikirana ya CPE imatha kulumikizidwa ndi kutentha kwambiri kapena kulumikizidwa ndi ma elekitironi kutentha kwa chipinda. Komabe, rabara yachikhalidwe ya chloroprene singathe kulumikizidwa ndi ma elekitironi, ndipo rabara yachikhalidwe ya styrene butadiene si yoyenera kulumikizidwa ndi ma elekitironi.
3. Kusintha kapangidwe ka zinthu za chingwe n'kopindulitsa
Ponena za mawaya ndi zingwe zotsika mphamvu, zimagawidwa m'magulu awiri malinga ndi momwe zimagwiritsidwira ntchito: mawaya omangira ndi zingwe zamagetsi. Chifukwa cha ubwino wake wambiri womwe mphira wopangidwa ulibe, CPE ingagwiritsidwe ntchito kwambiri popanga zingwe zamagetsi zosinthika m'nyumba ndi zingwe zina zamagetsi zosinthika.
