Kusankha pulasitiki yoyenera ndi chimodzi mwazosankha zofunika kwambiri pakupanga extrusion. Kuchokera pakupanga kusanja mpaka kumveka bwino, zinthu zomwe mumasankha zimakhudza kwambiri momwe zinthu zanu zimagwirira ntchito komanso moyo wanu womaliza. Kumvetsetsa kusiyana kwakukulu pakati pa zipangizo zamapulasitiki zomwe zimagwiritsidwa ntchito popanga extrusion kungathandize opanga kupanga zisankho zodziwika bwino, zokhudzana ndi ntchito.
Tiyeni tifufuze mawonekedwe ofunikira, zofunikira pakukonza, ndi zotsatira zomaliza za mapulasitiki omwe amagwiritsidwa ntchito kwambiri potulutsa.
PVC: Kusiyanasiyana Kumakumana ndi Kukaniza kwa Chemical
Polyvinyl chloride (PVC) imagwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wabwino kwambiri, kutheka kwake, komanso kulimba kwake. Imapezeka m'njira zolimba komanso zosinthika, PVC imalimbana ndi mankhwala, kuwonekera kwa UV, ndi chinyezi, zomwe zimapangitsa kuti ikhale yabwino pamapaipi, mbiri, ndi ntchito zakunja.
Mu extrusion, PVC imayenda pakati pa 160 ° C ndi 210 ° C. Pamafunika mbiri yoyendetsedwa bwino ya kutentha ndi kapangidwe ka screw zomwe zimathandizira kusungunuka kokhazikika ndikupewa kuwonongeka. Kapangidwe kake kamene kamalepheretsa kuyaka kwa moto komanso mphamvu zotchinjiriza bwino zimathandizanso kuti ikhale yabwino kwambiri pamagetsi.
PE: Yopepuka komanso Yosagwirizana ndi Impact
Polyethylene (PE), makamaka mumitundu yake ya HDPE ndi LDPE, imadziwika ndi kusinthasintha kwake, kukana kukhudzidwa, komanso kuyamwa kochepa kwa chinyezi. Ndizinthu zopititsira ku machubu, mafilimu olongedza, ndi mapaipi amadzi.
PE imatuluka bwino pa 160-230 ° C, yokhala ndi zomangira zomwe zimagogomezera kumeta kochepera komanso kutulutsa kwakukulu. Kumapeto kwake kosalala komanso kukana kwambiri kwamankhwala kumapangitsa kuti ikhale yoyenera mayendedwe amadzimadzi komanso kugwiritsa ntchito chakudya. Mwa zida zonse zapulasitiki zopangira extrusion, PE imadziwika chifukwa cha kulimba kwake m'malo ovuta.
PP: Kukhazikika kwa Chemical ndi Kukhazikika
Polypropylene (PP) imapereka kuphatikiza kwapadera kwa kuuma komanso kukana kwamankhwala. Ili ndi malo osungunuka kwambiri kuposa PE ndipo imapereka kukana kutopa kwambiri, ndikupangitsa kuti ikhale yoyenera zida zamagalimoto, zida za labotale, ndi mahinji amoyo.
PP imachita pa kutentha kwapamwamba pang'ono (200-280 ° C), ndipo imafunikira wononga ndi zosakaniza zolimba ndi zopanikizana kuti zitsimikizire kusungunuka kofanana. Ndiwopepukanso ndipo imalimbana bwino ndi ma asidi ndi zoyambira, zabwino m'malo omwe kukhudzidwa kwamankhwala kumakhala kofala.
ABS: Kulimba ndi Surface Finish Quality
Acrylonitrile Butadiene Styrene (ABS) imasankhidwa pamene kukana kwamphamvu ndi mawonekedwe apamwamba ndizofunikira kwambiri. Zomwe zimapezeka kwambiri pazinthu zogulira ndi nyumba zamagetsi, ABS imaphatikiza kulimba ndi kukhazikika kwabwino.
Kutulutsa ABS kumafuna kutentha kwapakati pa 190-240 ° C, ndi zometa pang'ono kuti zipewe chikasu kapena zolakwika. Ngakhale ABS sichiri kugonjetsedwa ndi UV popanda zowonjezera, chiŵerengero cha mphamvu ndi kulemera kwake chimapangitsa kuti ikhale yotchuka pamapulogalamu apamwamba kwambiri.
PC: Kuwonekera Kwambiri ndi Kukaniza Kutentha
Polycarbonate (PC) imakondedwa chifukwa chowonekera, kukhazikika kwamafuta, komanso mphamvu yayikulu. Amagwiritsidwa ntchito nthawi zambiri pazovundikira zowunikira, mapanelo odzitchinjiriza, ndi zida zamankhwala komwe kumveka bwino komanso mphamvu ndizofunikira.
Kutulutsa kwa PC kumafuna kutentha kwapakati pa 240-300 ° C ndi zomangira za torque yayikulu yokhala ndi kukameta ubweya wowongolera. Pakati pa zinthu zapulasitiki zopangira extrusion, PC imafuna kuwongolera kutentha koyenera kuti zisatengeke chikasu kapena brittleness. Kuwonekera kwake kwa kuwala kumapangitsa kukhala chisankho chapamwamba pa mapulogalamu omwe amafunikira mawonekedwe apamwamba komanso kufalitsa kuwala.
Kufananiza Zinthu ndi Ntchito: Chinsinsi cha Chipambano
Kusankha zinthu zapulasitiki zolondola kuti ziwonjezeke sikungotengera mtengo kapena kupezeka kwake, koma kugwirizanitsa magwiridwe antchito ndi zomwe mukufuna kugwiritsa ntchito. Mukufuna kukana kwakukulu kwa UV kuti mugwiritse ntchito panja? PVC kapena PE yopangidwa mwapadera ingakhale yabwino kwambiri. Mukuyang'ana mapanelo omveka bwino, olimba? Ganizirani za PC. Pazotengera zosagwirizana ndi mankhwala, PP ndiye ochita bwino kwambiri.
Zida zapulasitiki zopangira extrusion zomwe mumasankha sizidzangowonetsa kumasuka kwa kukonza komanso kupambana kwanthawi yayitali kwa mankhwala anu m'munda.
Mukuyang'ana kukhathamiritsa mzere wanu wa extrusion ndi zida zapulasitiki zoyenera? Gwirizanani ndiJWELLlero-mnzako wodalirika mu njira zapamwamba extrusion ndi ukatswiri zipangizo.
