Kanema Wapamwamba Kwambiri Wolemera Wolemera Wa polyethylene
Ntchito:
Maenvulopu osalala komanso njanji pamakina odzaza mabotolo, makina olembera, makina ogulitsa, ndi zina zambiri.
Zivundikiro za zovundikira lamba wa conveyor ndi nsonga zamatebulo zamakina osiyanasiyana otumizira.
Maenvulopu opangira ma mandrel amitundu yosiyanasiyana yamakina opanga mafilimu ndi mapepala.
Kwa gasket lining.
Liners kwa mitundu yosiyanasiyana yotulutsa pansi.
Zinthu zotsetsereka zotsetsereka pazida zam'nyumba ndi makina odziwikiratu.
Kutsetsereka kwa zinthu zotsetsereka za makope.
Zinthu zotsetsereka zotsetsereka pamakina a fiber.
Zinthu zotsetsereka pamakina omangirira mabuku.
Zinthu zotsetsereka zopangira makina osindikizira.
Tengani mbewa pad mwachitsanzo:
Poyerekeza ndi Teflon (polytetrafluoroethylene PTFE), zinthu zomwe zimagwiritsidwa ntchito m'mapadi a mbewa zachikhalidwe, filimu yopitilira muyeso yamamolekyulu ya polyethylene UPE ndiyosamva kuvala. Malo odzipangira okha mafuta a UPE ali pafupi ndi a Teflon. Panthawi imodzimodziyo, malinga ndi mtengo, kachulukidwe ka filimu yochuluka kwambiri ya polyethylene UPE ndi yochepa kwambiri, ndipo ultra-high molecular weight polyethylene (UPE) ndi 50% yotsika kuposa Teflon mu kutembenuka kwakukulu. Chifukwa chake, filimu yochuluka kwambiri ya polyethylene (UPE) yasintha pang'onopang'ono ferroazol ngati chisankho choyamba pazida zopangira zoyambira.
Kugwiritsa ntchito pa tepi:
Tepi yomatira yotengera kukakamiza kutengera filimu ya UHMWPE komanso yokhala ndi liner yotulutsa. Poyerekeza ndi matepi ena omatira pogwiritsa ntchito filimu ya utomoni, kukana kwake ndikokwera, kukana kwa abrasion ndi kudzipaka mafuta bwino.
Kukula kokhazikika
| Makulidwe | M'lifupi | Mtundu |
| 0.1 ~ 0.4mm | 10-300 mm | wakuda, woyera kapena makonda |
| 0.4-1 mm | 10-100 mm |
Chiyambi cha UHMWPE:
Polyethylene yapamwamba kwambiri (UHMW-PE) imatanthawuza polyethylene yozungulira yomwe imakhala yolemera kwambiri kuposa 1.5 miliyoni. Chifukwa cha kulemera kwake kwa mamolekyulu (polyethylene wamba ndi 20,000 mpaka 300,000, UHMW-PE ili ndi magwiridwe antchito osayerekezeka poyerekeza ndi polyethylene wamba ndi mapulasitiki ena auinjiniya:
1) Kukaniza kwambiri kuvala, nthawi 4 kuposa nayiloni 66 ndi PTFE, nthawi 6 kuposa carbon steel, yabwino kwambiri pakati pa ma resin opangidwa panopa.
2) Mphamvu yamphamvu kwambiri, yomwe ndi 2 nthawi ya polycarbonate ndi nthawi 5 ya ABS, ndipo imatha kukhala yolimba kwambiri pa kutentha kwa nayitrogeni wamadzimadzi (-196 ℃).
3) Katundu wabwino wodzitchinjiriza, katundu wake wodzitchinjiriza ndi wofanana ndi wa PTFE, ndipo friction coefficient ndi 0.07-0.11 yokha; ndi 1/4-1/3 yokha ya chitsulo chosakanikirana chachitsulo.
4) Mtengo wamayamwidwe amphamvu ndiwokwera kwambiri pakati pa mapulasitiki onse, ndipo mphamvu yochepetsera phokoso ndiyabwino kwambiri.
5) Ili ndi kukhazikika kwamphamvu kwamankhwala ndipo imatha kukana zofalitsa zowononga zosiyanasiyana komanso media organic mkati mwa kutentha kwina ndi ndende.
6) Kuthekera kwamphamvu kotsutsana ndi kumamatira, kwachiwiri kwa "Plastic King" PTFE.
7) Zaukhondo kwathunthu komanso zopanda poizoni, zitha kugwiritsidwa ntchito pokhudzana ndi chakudya ndi mankhwala.
8) Kachulukidwe ndi kakang'ono kwambiri pakati pa mapulasitiki onse a engineering, 56% yopepuka kuposa PTFE ndi 22% yopepuka kuposa polycarbonate; kachulukidwe ndi 1/8 yachitsulo, ndi zina zotero.
Chifukwa cha magwiridwe antchito apamwambawa, UHMW-PE imatchedwa "pulasitiki yodabwitsa" ndi mayiko aku Europe ndi America ndipo yayamikiridwa komanso kugwiritsidwa ntchito kwambiri m'mafakitale ambiri.
