Ubwino wogwiritsa ntchito chlorinated polyethylene pazingwe zapaintaneti

1. Kupititsa patsogolo luso lazinthu zamagetsi
Ukadaulo wa CPE uli ndi magwiridwe antchito athunthu, kuyimitsa moto kwabwino kwambiri komanso kukana kwamafuta, kukana kukalamba kwabwino, kukana kwa ozoni, kukana kwanyengo, komanso magwiridwe antchito abwino osakanikirana. Zilibe pafupifupi zotentha komanso zosungirako nthawi yayitali popanda kuwonongeka, ndikuzipanga kukhala chingwe chabwino.
Kutentha kwanthawi yayitali kwa CPE ndi 90 ℃, ndipo malinga ngati chilinganizo chili choyenera, kutentha kwake kokwanira kumatha kufika 105 ℃. Kugwiritsa ntchito CPE kumatha kuwonjezera kuchuluka kwa zingwe za mphira kuchokera ku 65 ℃ mpaka 75-90 ℃ kapena 105 ℃ m'maiko otukuka kunja. CPE zomatira palokha ndi yoyera ngati matalala, kotero kaya imagwiritsidwa ntchito ngati kutchinjiriza kapena sheath, imatha kupangidwa kukhala zinthu zokongola malinga ndi zosowa za ogwiritsa ntchito. Komabe, zinthu wamba monga mphira wachilengedwe, rabala ya styrene butadiene, rabala ya chloroprene, ndi rabala ya nitrile ndizovuta kutulutsa mitundu yoyera kapena yokongola chifukwa cha chikasu. Komanso, ambiri ntchito mphira chloroprene ndi mphira chlorosulfonated polyethylene zovuta kuthetsa mavuto monga monomer ndi zosungunulira kawopsedwe, volatilization, etc. pa ndondomeko kupanga. Posungira, mayendedwe, ndi kupanga zingwe, zovuta monga zotentha ndi zomata zodzigudubuza zimachitika nthawi zambiri. Kwa CPE, nkhani zoyambitsa mutu izi sizikhalapo. Mfundo ina yofunika kukumbukira ndi yakuti pamene chlorination imagwiritsidwa ntchito pazitsulo zotsika kwambiri, sizingaipitsa pachimake cha mkuwa, zomwe mosakayika zimathandizira luso lamakono la chingwe.
2. Lonse ndondomeko kusinthasintha, mtengo wotsika, ndi phindu
Pambuyo extruded ndi mphira extruder, CPE wothira mphira akhoza thermally crosslinked pa kutentha kapena crosslinked ndi elekitironi walitsa kutentha firiji. Komabe, mphira wamba wa chloroprene sungathe kuwoloka ndi kuwala kwa ma elekitironi, ndipo mphira wamba wachilengedwe wa styrene butadiene siwoyenera kuwoloka waya.
3. Kusintha kapangidwe kazinthu zamagetsi ndikopindulitsa
Ponena za mawaya otsika kwambiri ndi zingwe, amagawidwa makamaka m'magulu awiri malinga ndi ntchito zawo: mawaya omanga ndi zida zamagetsi. Chifukwa cha zabwino zake zambiri zomwe mphira wopangira alibe, CPE imatha kugwiritsidwa ntchito kwambiri popanga mawaya amagetsi apanyumba ndi zingwe zina zamagetsi zamagetsi.
