Polyethylene sera, yomwe imadziwikanso kuti sera ya polima, imagwiritsidwa ntchito kwambiri chifukwa cha kuzizira kwambiri, kukana kutentha, kukana mankhwala, komanso kuvala.Pakupanga kwabwinobwino, sera iyi imatha kuwonjezedwa mwachindunji ku polyolefin ngati chowonjezera, chomwe chimatha kukulitsa kukongola ndi kukonza magwiridwe antchito a mankhwalawa.Monga mafuta, imakhala ndi mankhwala okhazikika komanso magetsi abwino.Poyerekeza ndi PVC ndi mafuta ena akunja, sera ya polyethylene imakhala ndi mphamvu yothira mkati.

Sera ya Fischer TropschAmapangidwa makamaka ndi ma linear, odzaza ndi ma alkanes okwera kwambiri okhala ndi mamolekyu olemera pakati pa 500 ndi 1000, omwe amachititsa kuti mankhwalawa akhale ndi mawonekedwe abwino a kristalo, malo osungunuka kwambiri, malo ocheperako osungunuka, otsika mafuta, kulowa pang'ono, kutsika pang'ono, kusungunuka kochepa. mamasukidwe akayendedwe, kuuma, kuvala kukana, ndi mkulu bata.

Kusiyana kwakukulu pakati pa Fischer Tropsch sera yopanga sera ndi polyethylene wax wamba ndikuti:
(1) Kulemera kwa mamolekyu.Kulemera kwa molekyulu ya sera ya Fischer Tropsch ndi yotsika kwambiri kuposa ya sera ya PE, yokhala ndi unyolo wocheperako wokhala ndi nthambi komanso crystallinity yayikulu.Ndiosavuta kulowa mu unyolo wapamwamba wamakina macromolecular, kuchepetsa kukhuthala kwa kusungunuka.Iwo ali otsika kusamuka pa processing ndi zoonekeratu kondomu kwenikweni mu siteji yotsatira.
(2) Fischer Tropsch sera ndi alkane yolumikizidwa mwachindunji yomwe ilibe zomangira ziwiri, imakhala ndi mphamvu yamphamvu ya antioxidant, ndipo mankhwalawa ali ndi kukana kwanyengo.

(3) Kukhuthala kwa sera ya Fischer Tropsch ndikotsika kwambiri kuposa sera ya PE.Pokhapokha mozungulira 10. Ndalama zochepa zimatha kukwaniritsa zofanana zokometsera.Kugwiritsa ntchito ndi 70-80% yokha ya sera ya PE.Sera ya Fischer Tropsch imagwirizana bwino ndi PVC ndipo imatha kugwiritsidwa ntchito ngati mafuta amkati ndi akunja.Itha kugwiritsidwa ntchito ngati mafuta abwino amkati kuti athe kuwongolera bwino mikhalidwe yometa ubweya, kulimbikitsa kuyenda, kuwongolera mikangano ndi kusungunuka, potero kumapangitsa kukhazikika kwamafuta.Panthawi imodzimodziyo, chifukwa cha crystallinity yapamwamba komanso mapangidwe apamwamba, sera ya Fischer Tropsch imathandizira mankhwala a PVC kuti akwaniritse bwino kwambiri thupi ndi kukonza katundu.Malinga ndi zosowa, njira ya Fischer Tropsch imatha kupanga ma alkanes okhala ndi utali wosiyanasiyana wa unyolo kuti asinthe kulemera kwa molekyulu ya chinthu chomaliza ndikupanga zinthu zingapo.

Waukulu limagwirira zochita za kunja lubricant
Kawirikawiri, mafuta akunja a PVC ndi sera yosungunuka kwambiri yopanda polarity kapena polarity yochepa, yosungunuka kwambiri ya 50-200 ℃, ndi kulemera kwakukulu kwa maselo.
Limagwirira ntchito ndi kugwiritsa ntchito kusagwirizana kwake kupanga mafuta wosanjikiza kunja kwa PVC kusungunula kapena otaya unit, kupititsa patsogolo kukangana pakati pa malo otaya mayunitsi ndi pakati pa kusungunuka ndi zitsulo pamwamba.Ndikosavuta kugwa pa kutentha kwambiri, koma sikophweka kugwa pa kutentha kwa firiji.

Zotsatira za mafuta pazamankhwala
Mafuta akunja, kupanga pulasitiki kuchokera kuchangu kupita pang'onopang'ono, magwiridwe antchito kuchokera kumtunda kupita kumunsi, komanso kutuluka kuchokera ku zoyipa kupita ku zabwino kupita ku zosokoneza.
Pa gawo loyambirira la extrusion processing, pamene tinthu tating'onoting'ono tating'ono tating'ono tating'onoting'ono tating'onoting'ono, malo osungunuka amafuta akunja amakhala okwera ndipo palibe kusungunuka, komwe sikungachedwetse pulasitiki.Pakatikati ndi pambuyo pake, kutentha kwa kusungunuka kumawonjezeka, ndipo mafuta osungunuka akunja amaphimba pakati pa kusungunula, moyenerera kuchedwetsa plasticization ndikuwongolera kumamatira ndi zitsulo, kuteteza kusungunuka kwakukulu kwa kusungunuka ndikupereka ntchito yabwino yowononga.
