Ma pellets apulasitiki owonekera

Ndi ubwino wa kulemera kwa kuwala, kulimba kwabwino, kumasuka kwa kuumba ndi kutsika mtengo, mapulasitiki akuchulukirachulukira m'malo mwa galasi muzogwiritsira ntchito zambiri, makamaka m'mafakitale opangira zida ndi ma CD, omwe akukula mofulumira.Komabe, zida zowoneka bwino komanso makampani onyamula katundu ali ndi zofunika kwambiri powonekera, kulimba, kukana kwamphamvu komanso kulimba.Choncho, chidwi chiyenera kulipidwa kwazopangira, njira, zida ndi nkhungukuwonetsetsa kuti zinthu zapulasitiki zimakwaniritsa zofunikira za zigawozo.Mukhozansokulumikizana ndi mainjiniya athumwachindunji kukambilana kwaulere.

Transparent pulasitiki khadi

Mapulasitiki oonekera ayenera poyamba kukhala ndi digiri yapamwamba yowonekera, chachiwiri ayenera kukhala ndi mphamvu zinazake ndi kukana kwa abrasion, okhoza kukana mphamvu, kukhala ndi kutentha kwabwino, kukhala ndi mankhwala abwino komanso kukhala ndi mlingo wochepa wa mayamwidwe amadzi, pokhapokha ngati angathe. amakwaniritsa zofunikira zowonekera pogwiritsidwa ntchito ndipo amakhala osasinthika kwa nthawi yayitali.PPT imagwiritsidwa ntchito pakuyika ndi zotengera chifukwa imayenera kutambasulidwa kuti ipeze makina abwino.

Zowonongeka zakuthupi, sungani zouma

Panthawi yodzaza, chidwi chiyenera kuperekedwa ku kusindikiza ndikuwonetsetsa kuti zopangira ndi zoyera.Makamaka, chinyezi chomwe chili muzinthu zopangira chingayambitse kuwonongeka pambuyo pa kutentha, kotero chiyenera kuuma, ndipo mu jekeseni, zinthuzo ziyenera kuwonjezeredwa pogwiritsa ntchito hopper youma.Mfundo inanso yofunika kuzindikira ndi yakuti panthawi yowumitsa, mpweya wolowetsayo uyenera kusefedwa ndi kuchotsedwa kuti usaipitse zopangira.

Kuthamanga kwa jekeseni ndi liwiro

Kachiwiri, monga mapulasitiki owonekera amakhala ndi malo osungunuka kwambiri komanso osayenda bwino, kuti atsimikizire mtundu wa chinthucho, kutentha kwa mbiya, kuthamanga kwa jekeseni, kuthamanga kwa jekeseni ndi magawo ena a ndondomeko ayenera kusinthidwa bwino kuti pulasitiki ya jekeseni idzaze. nkhungu osati kutulutsakupsinjika kwamkati ndikuyambitsa kusinthika kwazinthu ndikusweka.

Kuyeretsa migolo, zomangira ndi zina

Kupewa kuipitsidwa kwa zipangizo ndi wononga ndi depressions pali zinthu zakale kapena zonyansa, makamaka osauka matenthedwe bata la utomoni alipo, kotero pamaso ntchito, pambuyo shutdown ntchito wononga kuyeretsa wothandizila.

Kuyimitsa kwakanthawi kuti muchepetse kutentha

Akayimitsa osakhalitsa, pofuna kupewa zopangira mu kutentha kwakukulu kukhala kwa nthawi yayitali, kuchititsa kuwonongeka, chowumitsira ndi kutentha kwa mbiya kuyenera kuchepetsedwa, monga PC, PMMA ndi kutentha kwina kwa mbiya ziyenera kuchepetsedwa mpaka 160 ℃ kapena zochepa. .(Kutentha kwa Hopper kwa PC kuyenera kuchepetsedwa kukhala pansi pa 100 ℃)

Mavuto omwe akuyenera kuzindikirika pamapangidwe a nkhungu (kuphatikiza kapangidwe kake)

Kupewa kusabwerera bwino, kapena kuzizira kosagwirizana komwe kumapangitsa kuti pulasitiki isaumbike bwino, kuwonongeka kwa pamwamba ndi kuwonongeka.

Kawirikawiri, mfundo zotsatirazi ziyenera kudziwika muzojambula za nkhungu.

1. Makulidwe a khoma ayenera kukhala ofanana momwe angathere ndipo malo otsetsereka ayenera kukhala aakulu mokwanira;2. Gawo la kusintha liyenera kukhala lozungulira pang'onopang'ono komanso losalala, kuteteza ngodya zakuthwa.Mphepete zakuthwa zimapangidwa, makamaka pazinthu za PC siziyenera kukhala ndi mipata;3. Mphukira.Wothamanga ayenera kukhala wamkulu komanso wandiweyani momwe angathere, ndipo malo a sprue ayenera kukhazikitsidwa molingana ndi ndondomeko ya shrinkage condensation, ndipo zitsime zozizira ziyenera kuwonjezeredwa ngati kuli kofunikira;4. Pamwamba pa nkhungu iyenera kukhala yowala komanso yoyera, yokhala ndi zovuta zochepa (makamaka zosakwana 0,8);5. Bowo lolowera mpweya.Kagawo ayenera kukhala okwanira kutulutsa mpweya ndi mpweya mu kusungunuka mu nthawi;6. Kupatula PET, makulidwe a khoma sayenera kukhala woonda kwambiri, nthawi zambiri osachepera 1mm.

Mavuto oti adziwike pakupanga jekeseni (kuphatikiza zofunikira zamakina opangira jakisoni)

Pofuna kuchepetsa kupsinjika kwamkati ndi zolakwika zamtundu wa pamwamba, mbali zotsatirazi za njira yopangira jekeseni ziyenera kudziwika.

1, ayenera kugwiritsa ntchito wononga wapadera, ndi osiyana kutentha jekeseni jekeseni nozzle makina akamaumba;2, kutentha kwa jekeseni mu utomoni wa pulasitiki sikuwola, ndikoyenera kugwiritsa ntchito kutentha kwapamwamba;3, kupanikizika kwa jekeseni: nthawi zambiri kumakhala kokwera kwambiri kuti muthane ndi vuto la kusungunuka kwa viscosity, koma kupanikizika ndikwambiri kumatulutsa kupsinjika kwamkati komwe kumayambitsidwa ndi kumasulidwa kovuta ndi kupunduka;4, liwiro la jakisoni: kukumana ndi vuto la kudzaza nkhungu, nthawi zambiri imayenera kukhala yotsika, ndi bwino kugwiritsa ntchito jekeseni wapang'onopang'ono-wapang'onopang'ono-wapang'onopang'ono 5, kugwira nthawi ndikuzungulira kuzungulira: pokumana ndi kudzazidwa kwazinthu, palibe chopindika, kuwira;ziyenera kukhala zazifupi momwe zingathere, kuti muchepetse kusungunuka mu nthawi ya mbiya;6, wononga liwiro ndi kupsyinjika m'mbuyo: m'malo kukumana khalidwe la plasticization, ayenera kukhala otsika momwe angathere, kuteteza kuthekera decompression;7, kutentha kwa nkhungu: kuziziritsa kwa mankhwalawa ndi kwabwino kapena koyipa, kukhudza kwabwino kumakhala kwakukulu, kotero kutentha kwa nkhungu kuyenera kuwongolera njirayo.Ngati n'kotheka, kutentha kwa nkhungu kukhale kokwera.

Zina

Pofuna kupewa kuwonongeka kwa mawonekedwe apamwamba, chotulutsacho chiyenera kugwiritsidwa ntchito mochepa panthawi yopangira jekeseni;Mukamagwiritsa ntchito zinthu zomwe zagwiritsidwanso ntchito siziyenera kupitilira 20%.

Pazinthu zina kupatula PET, chithandizo cham'mbuyo chiyenera kuchitidwa kuti athetse kupsinjika kwamkati.PMMA iyenera kuuma pa 70-80 ° C kwa maola 4 mumlengalenga wotentha;PC ayenera zouma mu mpweya woyera, glycerine.Parafini yamadzimadzi etc. imatenthedwa pa 110-135 ° C ndipo nthawi imadalira mankhwala, mpaka maola oposa 10 amafunikira.PET, kumbali ina, imayenera kuyang'ana mbali ziwiri kuti ipeze makina abwino.

Kumangira jekeseni kumagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo kumatha kukwaniritsa kupanga kosasunthika, kolondola kwambiri kwa magawo munthawi yochepa.Malingaliro a kampani ProLean Techimapereka ntchito zopangira jakisoni pazinthu zambiri, kuphatikiza mapulasitiki ndi ma elastomer.Mwachidulekwezani chitsanzo chanundipo pezani mawu ofulumira aulere ndi malangizo okhudzana ndi mautumiki.
