Momwe Mungasankhire Zida Zapulasitiki Zabwino Kwambiri Zopangira Majekeseni Apulasitiki
Kusankha pulasitiki yoyenera yopangira jekeseni wa pulasitiki kungakhale kovuta-pali zosankha zambiri pamsika zomwe mungasankhe, zambiri zomwe sizingagwire ntchito yomwe mwapatsidwa. Mwamwayi, kumvetsetsa mozama za zinthu zomwe mukufuna komanso zomwe mukufuna kuzigwiritsa ntchito kungathandize kuchepetsa mndandanda wazomwe mungachite kuti mukhale chinthu chotheka kutha. Poganizira momwe mungagwiritsire ntchito, m'pofunika kukumbukira mafunso otsatirawa:
Kodi gawolo lidzagwiritsidwa ntchito kuti?
Imagwira ntchito nthawi yayitali bwanji?
Ndi zovuta zotani zomwe zimakhudzidwa ndikugwiritsa ntchito?
Kodi kukongola kumagwira ntchito, kapena kuchitapo kanthu kofunika kwambiri?
Kodi zovuta za bajeti pakugwiritsa ntchito ndi zotani?
Mofananamo, mafunso omwe ali pansipa ndi othandiza pozindikira zomwe mukufuna:
Ndi mawonekedwe otani amakina ndi makemikolo omwe amafunikira mu pulasitiki?
Kodi pulasitiki imagwira ntchito bwanji ikatenthetsa ndi kuziziritsa (mwachitsanzo, kufutukuka ndi kuchepa kwa kutentha, kutentha kwa kutentha, kutentha kowonongeka)?
Kodi pulasitiki imalumikizana bwanji ndi mpweya, mapulasitiki ena, mankhwala, ndi zina?
Pansipa pali tebulo la mapulasitiki omangira jakisoni wamba, iliyonse ili ndi zabwino zake komanso ntchito zake zonse zamakampani:
Zofunika
General Industry Application
ubwino

High Impact Polystyrene (HIPS)
chofunika
Zotsika mtengo, zopangidwa mosavuta, zokongola, makonda
Polyvinyl mankhwala enaake (PVC)
chofunika
Yolimba, yosagwira, yosamva malawi, osateteza
Acrylic (PMMA, Plexiglass, etc.)
Engineering
Zosalowetsedwa (galasi, fiberglass, ndi zina), zosagwirizana ndi kutentha, kusatopa
Acrylonitrile Butadiene Styrene (ABS)
Engineering
Zolimba, zosagwira kutentha, zokongola, zotetezeka ku mankhwala
Polycarbonate (PC)
Engineering
Zosagwira, zowoneka bwino, zosagwirizana ndi kutentha, zokhazikika
Nylon (PA)
Engineering
Zosalowetsedwa (galasi, fiberglass, ndi zina), zosagwirizana ndi kutentha, kusatopa
Polyurethane (TPU)

Zosatha kuzizira, zolimbana ndi abrasion, zolimba, zolimba zolimba
Polyetherimide (PEI)
Magwiridwe
Mphamvu yapamwamba, yolimba kwambiri, yokhazikika, yosamva kutentha
Polyether Ether Ketone (PEEK)
Magwiridwe
Kusamva kutentha, kusawotcha moto, kulimba kwambiri, kukhazikika pang'ono
Polyphenylene Sulfidi (PPS)
Magwiridwe
Kukaniza kwabwino konsekonse, kuletsa moto, kugonjetsedwa ndi chilengedwe
Thermoplastics ndiye njira yabwino yopangira jakisoni. Pazifukwa zambiri monga recyclability ndi mosavuta processing. Ndiye komwe mankhwala amatha kupangidwa ndi jekeseni pogwiritsa ntchito thermoplastic, tsatirani izi. Zopangira zosinthika kwambiri kwa nthawi yayitali zapangitsa kuti pakhale ma thermoset elastomers. Lero muli ndi mwayi wosankha ma thermoplastic elastomers. Kotero kuti gawo lanu liyenera kukhala losinthasintha kwambiri sikuchotsa mwayi wogwiritsa ntchito thermoplastics. Palinso magulu osiyanasiyana a ma TPE kuchokera ku chakudya kupita ku ma TPE ochita bwino kwambiri.
Mapulasitiki amtengo wapatali amagwiritsidwa ntchito pazinthu zogula tsiku ndi tsiku. Zitsanzo ndi makapu a khofi a polystyrene, mbale zotengera za polypropylene, ndi zipewa za botolo za polyethylene zolimba kwambiri. Ndizotsika mtengo komanso zopezeka. Mapulasitiki aumisiri amagwiritsidwa ntchito, monga dzina limatanthawuzira, ntchito zaumisiri. Muwapeza m'nyumba zobiriwira, zofolera, ndi zida. Zitsanzo ndi polyamides (Nayiloni), polycarbonate (PC), ndi acrylonitrile butadiene styrene (ABS). Amatha kupirira mikhalidwe yovuta kwambiri ya chilengedwe. Zitha kupirira katundu ndi kutentha kwambiri kuposa kutentha kwa chipinda. Mapulasitiki apamwamba amagwira ntchito bwino pansi pazimene zinthu ndi mapulasitiki a engineering amalephera. Zitsanzo za mapulasitiki ogwira ntchito kwambiri ndi polyethylene ether ketone, polytetrafluoroethylene, ndi polyphenylene sulfide. Amatchedwanso PEEK, PTFE, ndi PPS. Amapeza kugwiritsidwa ntchito pamapulogalamu apamwamba kwambiri monga zakuthambo, zida zamankhwala, ndi magiya. Kuchita bwino kumakhala kokwera mtengo kuposa chinthu kapena mapulasitiki a engineering. Makhalidwe a pulasitiki amakuthandizani kusankha chomwe chikugwirizana ndi ntchito inayake. Mwachitsanzo, mapulogalamu ena amafuna zida zolimba koma zopepuka. Pachifukwa ichi, mumafananiza kachulukidwe kawo ndi mphamvu zawo.
