Allon Sake Buga Ƙwallon Ƙafa | Sake Buga Ƙwallon Ƙafa | Kayan Aikin Horar da Ƙwallon Ƙafa

1. Inganta juriyar lalacewa. Ɗaya daga cikin mafi kyawun halaye na polyethylene na UHMW shine juriyar gogewa mai matuƙar yawa, wanda yake da matuƙar amfani a aikace-aikacen injiniya da yawa. Daga cikin dukkan robobi, juriyar lalacewa ita ce mafi kyau, har ma juriyar lalacewa ta yau da kullun na kayan ƙarfe da yawa (kamar ƙarfen carbon, bakin ƙarfe, tagulla, da sauransu) ba ta da kyau kamar ta. Yayin da nauyin ƙwayoyin polyethylene ke ƙaruwa, kayan yana ƙara juriyar lalacewa.

2. Juriyar tasiri mai matuƙar yawa. Ƙarfin tasirin polyethylene mai nauyin ƙwayoyin halitta mai matuƙar yawa yana da alaƙa da nauyin ƙwayoyin halitta. Lokacin da nauyin ƙwayoyin halitta ya ƙasa da miliyan 2, ƙarfin tasirin yana ƙaruwa tare da ƙaruwar nauyin ƙwayoyin halitta, kuma ya kai kololuwa kusan miliyan 2. Bayan kololuwa, ƙarfin tasirin yana ƙaruwa tare da nauyin ƙwayoyin halitta. Wannan saboda sarkar ƙwayoyin halitta ba ta da kyau kuma tana hana ɗaukar hoto, don haka akwai babban yanki mara tsari a cikin macromolecule, wanda zai iya shan babban kuzarin tasiri.

3. Ƙarancin ƙarfin gogayya. UHMWPE yana da juriya sosai ga lalacewa, yana da ƙarancin ƙarfin gogayya da kuma kyakkyawan man shafawa, kuma abu ne mai kyau don ɗaukar bushings, sliders da linings.

Amfani da polyethylene mai nauyin kwayoyin halitta mai matuƙar yawa a matsayin ɓangaren gogayya na kayan aikin ba wai kawai zai iya inganta rayuwar da ke jure lalacewa ba, har ma yana adana kuzari.

4. Kyakkyawan juriya ga sinadarai. Polyethylene mai nauyin kwayoyin halitta mai matuƙar yawa yana da kyakkyawan juriya ga lalata sinadarai. Banda sinadarin nitric mai yawa da sinadarin sulfuric mai yawa, ba zai lalace a cikin dukkan ruwan leda da ruwan acid ba, kuma ana iya amfani da shi a cikin sinadarin hydrochloric mai yawa a zafin jiki (80°C, Hakanan yana da ƙarfi a cikin sinadarin nitric acid <20%, sinadarin sulfuric acid <75%, kuma yana da ƙarfi a cikin ruwa, wankewa da ruwa.)

Duk da haka, polyethylene mai nauyin kwayoyin halitta yana da sauƙin kumbura a cikin mahaɗan ƙanshi ko halogenated (musamman a yanayin zafi mai yawa), don haka ya kamata a ba da kulawa ta musamman yayin amfani.

5. Rashin shan ruwa sosai. UHMWPE yana da ƙarancin shan ruwa, kusan ba ya shan ruwa, baya kumbura a cikin ruwa, kuma yana da ƙarancin shan ruwa fiye da nailan.

6. Halayen zafi. Dangane da hanyar ASTM (nauyi 4.6kg/cm2), zafin murɗewar zafi shine 85℃. A ƙarƙashin ƙaramin kaya, zafin sabis ɗin zai iya kaiwa 90℃. A lokuta na musamman, ana ba da izinin amfani da shi a mafi girman zafin jiki. Polyethylene mai nauyin ƙwayoyin halitta abu ne mai matuƙar tauri, don haka ƙarancin juriyarsa ma yana da kyau sosai, kuma har yanzu yana da wani matakin sassauci a ƙananan zafin jiki na -269°C, kuma babu alamar murɗewa.

7. Halayen Wutar Lantarki. UHMWPE yana da kyawawan halaye na lantarki a cikin kewayon zafin jiki mai faɗi, juriyar girmansa shine 10-18CM, ƙarfin wutar lantarki mai lalacewa shine 50KV/mm, kuma ma'aunin dielectric ɗinsa shine 2.3. A cikin kewayon zafin jiki da mita mai faɗi, halayen wutar lantarkinsa ba sa canzawa sosai. A cikin kewayon zafin jiki mai jure zafi, ya dace sosai don amfani da shi azaman kayan gini a cikin injiniyan lantarki da kayan aiki a cikin injinan takarda.

8. Polyethylene mai nauyin kwayoyin halitta mai guba ba shi da ɗanɗano, ba shi da guba, ba shi da ƙamshi, ba ya lalata, kuma yana da zagayawar jiki da kuma daidaitawar jiki. Hukumar Abinci da Magunguna ta Amurka (FDA) da Ma'aikatar Aikin Gona ta Amurka (USDA) sun ba da izinin amfani da shi wajen hulɗa da abinci da magunguna.

Halayensa, musamman juriyar lalacewa, juriyar tasiri, da kuma kaddarorin mai da kansa, sune mafi kyau a cikin robobi na injiniya.
