1. Makhalidwe a kuwonjezera kosayenera kwa mafuta akunja muzinthu za thovu la PVC
Sera ya parafini ndiPE sera ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri pozembera panja popanga thovu.Sera ya parafini ndiyosavuta kugwa, kotero sera ya PE imagwiritsidwa ntchito nthawi zambiri.

Kupaka kunja sikukwanira, kutentha kwa zone 4 ndi 5 za extruder sikophweka kulamulira, ndipo ndikosavuta kupitirira kutentha.Pali matuza, matuza, chikasu ndi akhakula mbale pamwamba pa mbale pamwamba;Kuwonjezeka kwa kutentha kwa kumeta ubweya wa ubweya kumayambitsa kuwonongeka kwa zinthu, chikasu ndi phala pamwamba pa mbale, kutsetsereka kwambiri kwakunja ndi kusungunuka kwapulasitiki, zomwe zimapangitsa kuti mkati mwa nkhungu kukhale mvula ndi mvula pamtunda wa chinthucho, chomwe chimakhala ndi khoma losagwirizana. makulidwe ndi kusakhazikika mmbuyo ndi mtsogolo kuyenda kwa zizindikiro zina pamtunda.
2. Makhalidwe a kuwonjezera kosayenera kwa mafuta amkati muzinthu za thovu la PVC
(1) Osakwanira kondomu mkati, osauka kubalalitsidwa kwa zipangizo, mkangano plasticization, zovuta kulamulira makulidwe a mankhwala, wandiweyani pakati ndi woonda mbali zonse za bolodi thovu, kumamatira ku nkhungu patsekeke ndi kutenthedwa m'deralo;Kupaka mafuta kwambiri mkati kumapangitsa kuti zinthu za thovu ziwonongeke ndipo kukana kutentha kumachepa;Pansi pa kutentha kwina ndi kuthamanga kwa kusungunuka, kumasandulika kukhala mafuta akunja, zomwe zimapangitsa kusalinganika kwa mafuta.

(2) Osakwanira kondomu mkati ndi kunja, mkulu kusungunuka mamasukidwe akayendedwe, mkulu plasticizing makokedwe, kwambiri kusungunula khoma adhesion, chikasu kuwola mzere pamwamba zinthu, osauka pamwamba kusalala ndi kuchepetsedwa makina katundu katundu;Mafuta amkati ndi akunja ndiwochulukirachulukira, torque ya pulasitiki ndi yaying'ono, ndipo pulasitiki yosungunuka mwachiwonekere ndiyosakwanira.Ngakhale kuti mankhwalawa ali ndi kusalala bwino, kukakamiza kumamatira kumakhala kosauka, komwe kumakhudza kwambiri makina a chinthucho.
(3) Pali mafuta ochepa amkati komanso mafuta owonjezera akunja, nthawi yopangira pulasitiki mwachiwonekere imatenga nthawi yayitali, torque ya plasticizing imachepetsedwa, mankhwalawo ndi ovuta kupanga ndipo amakhala osalimba;Pali zodzoladzola zambiri zamkati komanso mafuta ochepa akunja, nthawi yopangira pulasitiki imafupikitsidwa kwambiri, pali chodabwitsa chomata khoma, nthawi yokhazikika yamafuta imafupikitsidwa, ndipo pamakhala mizere yachikasu yowola pamtunda.

Kuchulukana kwakukuluwothiridwa ndi polyethylene sera ndi lubricant wochita bwino kwambiri mkati ndi kunja, wopereka pulasitiki wabwino kwambiri komanso wotsitsa.

3. Kupaka mkati ndi kunja sikukwanira, kusungunuka kwa viscosity ndikokulirapo, torque ya plasticizing ndi yayikulu, kusungunuka kwa khoma kumamatira chodabwitsa, zinthu zakuthupi zimakhala ndi malire achikasu, kusalala kwa pamwamba ndi koyipa, komanso makina amakina. mankhwala ndi otsika;
Mafuta amkati ndi akunja ndi ochulukirapo, torque ya pulasitiki ndi yaying'ono, ndipo kusungunula pulasitiki mwachiwonekere sikukwanira.Ngakhale kuti mankhwalawa ali ndi kusalala bwino, kuthamanga kwa mfundo kumamatira kumakhala kosauka, komwe kumakhudza kwambiri makina a mankhwala;
Ndi mafuta ochepa amkati komanso mafuta ochulukirapo akunja, nthawi yopangira pulasitiki mwachiwonekere imatenga nthawi yayitali, torque ya plasticizing imachepetsedwa, ndipo mankhwalawo ndi ovuta kupanga ndi kuphulika;
Mafuta ochulukirapo amkati, kuthira kocheperako kwakunja, kufupikitsa nthawi yopangira pulasitiki, kumamatira pakhoma, kukhazikika kwanthawi yayitali, ndikuwola mizere yachikasu pamtengo.
