Kumanga kwa Die Kudakali Vuto Lalikulu pa Kutulutsa Polymer

Kuchuluka kwa ma die-building ndi chimodzi mwa mavuto omwe amakumana nawo kwambiri pakutulutsa ma polima. Kaya kupanga ma waya ndi ma cable compounds, mafilimu ophulika, mapaipi, ma profiles, kapena zinthu zapulasitiki zaukadaulo, ma polima processors amatha kukhala ndi zinthu zozungulira die atatha kugwira ntchito mosalekeza.

Ngakhale kuti kusonkhanitsa zinthu zambirimbiri poyamba kungaoneke ngati vuto laling'ono pokonza, kusonkhanitsa zinthu zambiri kungakhudze pang'onopang'ono kukhazikika kwa extrusion, mawonekedwe a zinthu, magwiridwe antchito a zinthu, komanso ndalama zopangira. Kuyeretsa pafupipafupi kumasokoneza kupanga, kumawonjezera kutaya kwa zinthu, komanso kuchepetsa kugwiritsa ntchito zida zonse.

Pamene liwiro la extrusion likupitirira kukwera ndipo mapangidwe a polima akukhala ovuta kwambiri, kuwongolera kuchuluka kwa ma die kwakhala kofunikira kwambiri kwa ma processor omwe akufuna kupanga kokhazikika komanso kwapamwamba.

Nkhaniyi ikufotokoza izi:

• Kodi kusungunuka kwa madzi m'thupi n'chiyani?
• Chifukwa chake zimachitika panthawi yotulutsa polima
• Ndi zinthu ziti zomwe zimakhudzidwa kwambiri
• Momwe zinthu zomwe zimagwiritsidwa ntchito pokonza zinthu zimakhudzira kuchulukana kwa zinthu
• Momwe ukadaulo wowonjezera wopangidwa ndi silicone ungathandizire kukulitsa kukhazikika kwa extrusion

Kodi Kumanga kwa Die ndi Chiyani?

Kuchuluka kwa ma die kumatanthauza kusonkhanitsa pang'onopang'ono kwa zotsalira za polima, zowonjezera, zodzaza, utoto, kapena zinthu zowonongeka kuzungulira kutuluka kwa die panthawi yotulutsa mosalekeza.

Kutengera ndi dongosolo la zinthu ndi momwe zinthu zilili, ndalama zomwe zasungidwa zitha kuwoneka motere:

• Kuipitsidwa kwa bulauni kapena wakuda
• Zotsalira za polima zomata
• Zinthu zopangidwa ndi kaboni
• Ma depositi oyera odzaza
• Kuipitsidwa kwa pamwamba pa mlomo wa die

Kuopsa kwa kupangika kwa ma die kumasiyana malinga ndi kapangidwe kake, zida zotulutsira, kutentha kwa kukonza, kuchuluka kwa kudulidwa, komanso kugwirizana kwa zowonjezera.

Ngati sizikulamulidwa bwino, zinthuzi zimatha kusamukira ku chinthu chotulutsidwa, zomwe zimakhudza mawonekedwe ndi kapangidwe kake.

N’chifukwa Chiyani Kufa Kumawonjezeka?

Kuchulukana kwa ufa nthawi zambiri kumachitika chifukwa cha chinthu chimodzi. M'malo mwake, nthawi zambiri kumachitika chifukwa cha kuyanjana kwa zinthu, kapangidwe kake, ndi momwe zinthu zimagwirira ntchito.

1. Kukangana Kwambiri kwa Polima-Chitsulo

Pa nthawi yotulutsa, polima wosungunuka amalumikizana nthawi zonse ndi screw, pirelo, ndi malo ouma.

Pakakhala kuuma kwambiri, kumamatira mwamphamvu pakati pa kusungunuka kwa polima ndi pamwamba pa chitsulo kungapangitse kuti zinthu zisonkhanire.

Zipangizo zokhala ndi kukhuthala kwakukulu kwa kusungunuka kapena mafuta osakwanira nthawi zambiri zimakhala zosavuta kugwidwa ndi vutoli.

2. Kudzaza Kwambiri

Mafakitale amakono a thermoplastic nthawi zambiri amakhala ndi zinthu zambiri zodzaza, monga:

• Aluminium hydroxide (ATH)
• Magnesium hydroxide (MDH)
• Kalisiyumu kabodi
• Talc
• Ulusi wagalasi

Ngakhale kuti zodzaza izi zimathandizira kuti moto uchepe kapena kuti ntchito yake ikhale yolimba, zimathanso kuwonjezera kukhuthala kwa kusungunuka ndi kukana kugwiritsa ntchito zinthu zina, zomwe zimapangitsa kuti kutulutsa kokhazikika kukhale kovuta.

3. Kutentha kwa Kukonza

Kutentha kwakukulu komanso kosakwanira kwa zinthu zopangira kungapangitse kuti zinthu zisawonongeke.

Kutentha kwakukulu kumatha kufulumizitsa kuwonongeka kwa polima kapena kusinthasintha kwa zinthu zina, pomwe kutentha kochepa kungachepetse kusungunuka kwa madzi ndikuwonjezera kupsinjika kwa shear.

Kusunga zenera loyenera lokonzekera ndikofunikira kwambiri kuti ntchito yotulutsa ikhazikike bwino.

4. Kupsinjika Kwambiri kwa Kudula

Kutulutsa kwakukulu kwa extrusion nthawi zambiri kumagwirizanitsidwa ndi liwiro lalikulu la screw komanso kupsinjika kwakukulu kwa shear.

Pamene kupsinjika kwa potulukira kwa die kupitirira mphamvu ya kusungunuka kwa polima kuyenda bwino, kusakhazikika kwa pamwamba kungachitike, zomwe zimawonjezera mwayi woti zinthu zisonkhanitsidwe mozungulira die.

Ndi Ma Polima Ati Omwe Amakhudzidwa Kwambiri?

Ngakhale kuti kusungunuka kwa madzi kumatha kuchitika m'zinthu zambiri za thermoplastic, nthawi zambiri kumawonekera m'magwiritsidwe ntchito monga:

• Kutulutsa filimu ya polyethylene (PE)
• Mankhwala a polypropylene (PP)
• Zingwe ndi waya zomwe zimakhala ndi mphamvu zambiri za ATH kapena MDH
• Mapulasitiki opangidwa ndi uinjiniya odzazidwa kwambiri
• Kutulutsa mapaipi
• Kutulutsa mbiri

Dongosolo lililonse la zinthu lili ndi makhalidwe osiyanasiyana ogwiritsira ntchito, kotero kusankha zowonjezera kuyenera kutengera kapangidwe kake ndi zofunikira zogwiritsira ntchito.

Kodi Zingatheke Bwanji?Zowonjezera Zochokera ku SiliconeThandizeni?

Njira imodzi yothandiza yochepetsera kuchulukana kwa ma die ndikuwongolera mafuta osungunuka ndikusintha momwe zinthu zimagwirizanirana ndi malo osungunuka a polymer ndi zitsulo.

Chipolopolo chachikulu cha silicone cholemera kwambiri chimayesedwa kawirikawiri pachifukwa ichi chifukwa chimatha kusintha momwe madzi amayendera popanda kusintha kwenikweni matrix a polima.

Mapindu omwe angakhalepo angaphatikizepo:

• Kuchepa kwa kukangana kwa polima ndi zitsulo
• Kukhazikika kwa kayendedwe ka madzi osungunuka bwino
• Mphamvu yotsika yotulutsa
• Malo oyeretsera zinthu zofewa panthawi yopanga zinthu mosalekeza
• Kuchepetsa kuchuluka kwa kuyeretsa die

Kagwiridwe ka ntchito kwenikweni kamadalira mtundu wa polima, kapangidwe kake kowonjezera, momwe zinthu zimagwiritsidwira ntchito, komanso kuchuluka kwa mlingo.

Chifukwa chiyani silikoni Masterbatch m'malo mwa mafuta odzola wamba?

Mafuta odzola achikhalidwe amatha kusintha momwe zinthu zilili pazifukwa zina, koma nthawi zina sangapereke mgwirizano pakati pa kugwira ntchito bwino kwa zinthu ndi kugwira ntchito bwino kwa pamwamba kwa nthawi yayitali.

Silicone masterbatch monga chowonjezera cha pulasitiki ndi chosinthira cha polima chimaphatikiza kusintha kwa kukonza ndi kukulitsa pamwamba, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna extrusion yokhazikika komanso mtundu wabwino wa chinthu chomalizidwa.

Kutengera kapangidwe kake, silicone masterbatch ingathandizenso:

• Kusalala bwino kwa pamwamba
• Kuchepa kwa kukangana
• Kukana kukanda ndi kukanda bwino

Mayankho a SILIKE Silicone Masterbatch a Extrusion Stability

SILIKE imapanga njira zothetsera vuto la silicone masterbatch zomwe zimapangidwira kuthandiza ma processor a polima kuthana ndi mavuto omwe amafala kwambiri pakugwiritsa ntchito thermoplastic.

Ndi chidziwitso pakuphatikiza silicone-polymer ndi chitukuko cha mapulogalamu, SILIKE imagwira ntchito ndi makasitomala kuti ayese kuyenderana kwa kapangidwe kake, kukonza momwe zinthu zimagwiritsidwira ntchito, ndikupangira mayankho a silicone masterbatch kutengera zofunikira zinazake zopangira.

Kugwiritsa ntchito kwa silicone masterbatch kumaphatikizapo:

•Ma waya ndi ma waya ophatikizika
•Kutulutsa filimu ya PE ndi PP
•Kutulutsa mapaipi ndi mbiri
•Mapulasitiki a magalimoto
• Mapulasitiki aukadaulo
• Zipangizo za TPU ndi TPE

Kuwunika kogwiritsa ntchito kumalimbikitsidwa kuti mupeze yankho loyenera kwambiri pa dongosolo lililonse la polima.

Mapeto

Kumanga kwa ufa ndi chinthu chovuta kwambiri chomwe chimakhudzidwa ndi makhalidwe a polima, kapangidwe ka kapangidwe kake, makina odzaza, ndi momwe amatulutsira. Ngakhale palibe yankho lachilengedwe, kumvetsetsa njira zomwe zimayambira kumathandiza opanga kupanga njira zokhazikika komanso zogwira mtima zokonzera.

Pa ntchito zambiri za thermoplastic, silicone masterbatch imapereka njira yothandiza yowongolera kayendedwe ka madzi osungunuka, kuchepetsa kukangana kwa polymer-metal, komanso kuthandizira kutulutsa koyera komanso kokhazikika.

Kudzera mu chitukuko choyang'ana pa ntchito komanso chithandizo chaukadaulo, SILIKE ikupitilizabe kuthandiza ma processor a polima kukonza magwiridwe antchito a extrusion ndikukweza magwiridwe antchito opangira zinthu zosiyanasiyana za thermoplastic.

Lumikizanani ndi SILIKE kuti mupeze ndemanga yaulere ya fomula komanso kuti mulandire Technical Data Sheet (TDS) yaSilike LYSI mndandanda wa silicone masterbatch(zowonjezera za polima zochokera ku siloxane). Gulu lathu la akatswiri lili okonzeka kupereka mayankho okonzedwa mwamakonda, zopempha zitsanzo, ndi chithandizo chokwanira chaukadaulo kuti chikuthandizeni kuthana ndi mavuto okonza zinthu. kuchepetsa Kumanga ndi Kutaya madzi, ndikuwonjezera mpikisano wa malonda anu!
