Ingabe ulayini we-twin-screw pelletizing uhlala ungcono kunomugqa we-screw single?
Cha. Ulayini we-twin-screw ohambisanayo unamandla uma inqubo kufanele ixube ama-polymer, ihlakaze okokugcwalisa noma i-pigment, yengeze izithako ngeziphakeli eziseceleni, noma isuse ukuguquguquka okukhulu. Ulayini onesikulufu esisodwa kuvame ukukhetha okuqondile lapho isitokwe esizinzile, esilungisiwe sidinga ikakhulukazi ukuncibilika, ukucwengwa, ukukhiqizwa kwengcindezi kanye nokusikwa kwe-pellet.
Imuphi umugqa we-pelletizing ongcono ku-PE noma i-PP egaywe kabusha?
Kuya ngesimo se-regrind. Umfudlana we-PE noma we-PP ohlungiwe, ogeziwe futhi ongaguquguquki kahle ungase ulingane nolayini wesikulufu esisodwa nokuphakelayo okulungile, ukukhipha umoya nokuncibilika. Ukwakheka okuxubile, ukungezwa kwesigcwalisi, ukususwa kwephunga noma okuguquguqukayo, kanye nokudingwa kwe-homogenization kungathethelela umugqa wesikulufu esikabili.
Imuphi umugqa okufanele ngiwukhethele i-masterbatch noma izinhlanganisela ezigcwaliswe kakhulu?
Qala ukuhlola ngomugqa we-twin-screw ohambisanayo ngenxa yokuthi ama-elementi ayisikulufu e-modular kanye nezindawo zokuphakelayo ezihlukene zinikeza ukulawula okwengeziwe phezu kokuxuba okusabalalisayo nokuhlakazayo. Uhlobo lwesihlungi, ukulayisha, ukuminyana kwenqwaba, ukuthunuka nokuhlakazeka okudingekayo kusanquma isiphakeli, ukumiswa kwezikulufu kanye nephakheji yokuguga.
Ingabe ulayini we-pelletizing onesikulufu esisodwa ungasebenzisa i-vacuum degassing?
Yebo. I-Nanhaiya inikezela nge-vacuum degassing njengenketho kulayini wayo we-screw pelletizing. Indawo yokukhipha umoya, izinga lokugcwalisa ngezikulufu, umswakama wesiphakeli, isivalo esincibilikisayo kanye nomthamo we-vacuum kufanele kusebenze ndawonye ukuze okubalulekile kungagcwalisi isikhala.
Uyini umehluko phakathi kwe-strand ne-water-ring pelletizing?
Isistimu ye-strand ikhipha izintambo eziqhubekayo, izipholise bese izisika zibe amapellets angama-cylindrical. Isistimu yeringi yamanzi inqamula ukuncibilika ebusweni bese ithwala ama-pellets emanzini. Ukuziphatha kwezinto ezibonakalayo, okuphumayo, izidingo zokushintsha, umumo we-pellet nokubandakanyeka komsebenzisi kufanele kunqume indlela.
Ingakanani i-Nanhaiya pelletizing lines engakhiqiza?
I-Nanhaiya ibala u-100 kg/h ngomugqa wayo we-pelletizing onesikulufu esisodwa kanye no-300 kuya ku-600 kg/h ngomugqa wayo ohambisanayo we-twin-screw pelletizing. Lokhu ukulungiselelwa komkhiqizo oshicilelwe, ngakho-ke ikhotheshini yokugcina kufanele isho ukwakheka okuqondile, isimo sokuphakelayo kanye nesisekelo sokwamukela somshini okhethiwe.
Yiluphi ulwazi okufanele ngiluthumele ngomugqa we-pelletizing RFQ?
Thumela amamaki e-polymer namaphesenti, ifomu lokuphakelayo, ukuminyana kwenqwaba, umswakama, ukungcoliswa kanye namazinga aguquguqukayo, izithasiselo nezihlungi, okukhiphayo okukhona nokuqondiwe, usayizi we-pellet, imfuneko yokuhlunga, izimo zensiza, ukwakheka kwesitshalo, izinga lokulawula kanye nokuhlolwa kokwamukelwa okulinganisekayo.
Ukudalulwa kwezentengiselwano: I-Nanhaiya ikhiqiza imigqa ye-pelletizing, izikulufu, imiphongolo kanye nezingxenye ze-extrusion ezixhunywe kulo mhlahlandlela. Ukukhetha kokugcina kuncike ezintweni zomthengi, ububanzi bomugqa obugunyaziwe, isivumelwano sobuchwepheshe nokuhlolwa kokwamukela.
