Kapangidwe kazinthu zama cell:
PMMA ndi njira yachuma ya polycarbonate (PC) pamene mphamvu zamakokedwe, flexural mphamvu, kuwonekera, polishability, ndi UV kulolerana ndi zofunika kwambiri kuposa mphamvu mphamvu, kukana mankhwala, ndi kutentha kukana.[6] Kuphatikiza apo, PMMA ilibe ma bisphenol-A omwe angakhale owopsa omwe amapezeka mu polycarbonate ndipo ndi chisankho chabwinoko chodula laser. Nthawi zambiri imakondedwa chifukwa cha zinthu zake zolimbitsa thupi, kunyamula mosavuta ndi kukonza, komanso kutsika mtengo. PMMA yosasinthidwa imachita zinthu mwachisawawa ikakhala yolemetsa, makamaka ikakhudzidwa, ndipo imakonda kukanda kuposa magalasi wamba, koma PMMA yosinthidwa nthawi zina imatha kukwaniritsa kukanda kwambiri komanso kukana.
Kupanga kwa Acrylic Prosthetic Mano Opangira Zojambula ndi zokongoletsa zimagwiritsa ntchito PMMA, mu malonda a Technovit 7200 amagwiritsidwa ntchito kwambiri pazachipatala. Amagwiritsidwa ntchito pa histology ya pulasitiki, ma electron microscopy, komanso ntchito zina zambiri. PMMA yagwiritsidwa ntchito popanga nembanemba zoyera kwambiri zowoneka bwino zomwe zimatha kusinthasintha ndikusintha mawonekedwe kuti ziwoneke ponyowa.[50] Acrylic imagwiritsidwa ntchito poyanika mabedi ngati malo owonekera omwe amalekanitsa wokhalamo ndi mababu otenthetsera akamawotcha. Mtundu wa acrylic womwe umagwiritsidwa ntchito poyanika mabedi nthawi zambiri umapangidwa kuchokera ku mtundu wapadera wa polymethyl methacrylate, pawiri yomwe imalola kutuluka kwa cheza cha ultraviolet. Mapepala a PMMA amagwiritsidwa ntchito kwambiri m'makampani opanga zikwangwani kupanga zilembo zodulidwa mosabisa mu makulidwe osiyanasiyana kuyambira mamilimita 3 mpaka 25 (0.1 mpaka 1.0 mkati). Zilembozi zitha kugwiritsidwa ntchito pazokha kuyimira dzina la kampani ndi/kapena logo, kapena zitha kukhala gawo la zilembo zowunikira. Acrylic imagwiritsidwanso ntchito kwambiri mumakampani opanga zikwangwani monga gawo lazizindikiro zapakhoma pomwe ingakhale chinsalu chakumbuyo, chojambulidwa pamwamba kapena chakumbuyo, chophimba chakumaso chokhala ndi zilembo zokwezeka kapena zithunzi zosindikizidwa mwachindunji, kapena spacer kupatukana. zizindikiro zigawo. PMMA idagwiritsidwa ntchito mu Laserdisc optical media. [51] (Ma CD ndi ma DVD amagwiritsa ntchito ma acrylic ndi polycarbonate kuti azitha kukana). Imagwiritsidwa ntchito ngati chiwongolero chowunikira pazowunikira kumbuyo mu TFT-LCDs. [kutchulidwa] Ulusi wa pulasitiki womwe umagwiritsidwa ntchito polumikizirana mtunda waufupi umapangidwa kuchokera ku PMMA, ndi perfluorinated PMMA, yovekedwa ndi fluorinated PMMA, munthawi yomwe kusinthasintha kwake komanso kuyika kotsika mtengo. mtengo wake umaposa kusalolera bwino kwa kutentha kwake komanso kutsika kwambiri kuposa ulusi wagalasi. PMMA, mu mawonekedwe oyeretsedwa, amagwiritsidwa ntchito ngati masanjidwewo mu laser utoto-doped organic olimba-boma kupeza media kwa tunable boma olimba utoto lasers.[52] Mu kafukufuku wa semiconductor ndi mafakitale, PMMA imathandizira ngati kukana munjira ya electron beam lithography. Yankho lopangidwa ndi polima mu zosungunulira ntchito kupota malaya sil
Chemwin ikhoza kupereka ma hydrocarbon ambiri ambiri ndi zosungunulira zamankhwala kwa makasitomala aku mafakitale.Izi zisanachitike, chonde werengani mfundo zotsatirazi zokhuza kuchita bizinesi nafe:
1. Chitetezo
Chitetezo ndicho chofunikira kwambiri chathu. Kuphatikiza pa kupatsa makasitomala chidziwitso chokhudza kugwiritsa ntchito bwino komanso kusamala zachilengedwe kwa zinthu zathu, tadziperekanso kuwonetsetsa kuti chiwopsezo chachitetezo cha ogwira ntchito ndi makontrakitala chikuchepetsedwa kukhala chocheperako komanso chotheka. Choncho, tikufuna kuti kasitomala awonetsetse kuti miyezo yoyenera yotsitsa ndi kusunga chitetezo ikukwaniritsidwa tisanaperekedwe (chonde onani zowonjezera za HSSE pazogulitsa zomwe zili pansipa). Akatswiri athu a HSSE atha kupereka chitsogozo pamiyezo iyi.
2. Njira yobweretsera
Makasitomala amatha kuyitanitsa ndikutumiza zinthu kuchokera ku chemwin, kapena atha kulandira zinthu kuchokera kumakampani athu opanga. Njira zoyendera zomwe zilipo zikuphatikiza magalimoto, njanji kapena ma multimodal (mikhalidwe yosiyana imagwira ntchito).
Pankhani ya zofuna za makasitomala, titha kufotokoza zofunikira za mabwato kapena akasinja ndikugwiritsa ntchito miyezo yapadera yachitetezo / kuwunika ndi zofunikira.
3. Kuchuluka kwa dongosolo lochepa
Ngati mumagula zinthu patsamba lathu, kuchuluka kwa madongosolo ocheperako ndi matani 30.
4.Kulipira
Njira yolipirira yokhazikika imachotsedwa mwachindunji mkati mwa masiku 30 kuchokera pa invoice.
5. Zolemba zotumizira
Malemba otsatirawa amaperekedwa pakubweretsa kulikonse:
· Bill of Lading, CMR Waybill kapena chikalata china chamayendedwe
· Satifiketi Yowunikira kapena Yogwirizana (ngati pakufunika)
· Zolemba zokhudzana ndi HSSE mogwirizana ndi malamulo
· Zolemba za kasitomu mogwirizana ndi malamulo (ngati pakufunika)
