Chii chinonzi density yePOM? Kuongorora kwakadzama kwezvinhu zvePOM zvinhu
Chii chinonzi density yePOM? Uyu mubvunzo wakakosha kune varapi veindasitiri yemakemikari uye mainjiniya emidziyo, POM (Polyoxymethylene) ipurasitiki yeinjiniya inoshandiswa zvakanyanya muindasitiri yekugadzira, uye hunyoro hwayo hune chekuita nemamiriro ekushandisa kwayo uye kuita kwayo. Iri bepa richaongorora zvakadzama kuwanda kwePOM, zvinofurira zvinhu uye kukosha kwayo mukushandisa zvinoshanda.
1. Basic sumo yePOM zvinhu
POM (polyoxymethylene) ndeye crystalline thermoplastic ine simba rakawanda, yakanaka kupfeka kusamira uye yakaderera coefficient yekupokana. Nekuda kweaya akanakisa emuviri zvimiro, POM inoshandiswa zvakanyanya mukugadzira magiya, mabhengi, masiraidhi, zvisungo uye zvimwe zvemakanika zvikamu. Usati wakurukura "chii chinonzi density yePOM", zvinodikanwa kuti unzwisise zvakakosha zvePOM, izvo zvinobatsira kunzwisisa zviri nani mhedzisiro yehuwandu hwayo pakuita kwayo. 2.
2. Numerical range yePOM density
Kazhinji, kuwanda kwePOM kunotangira pa1.41 g/cm³ kusvika 1.43 g/cm³. Kunyanya, iyo density yePOM inonyanya kupesvedzerwa nechimiro chepolymer cheni uye maparamendi anoshandiswa panguva yekugadzira. Nekuti POM ine yakakwira dhigirii rekristaro, izvi zvinokonzeresa kune yakawedzera density, iyo iri pakati pepamusoro pepakati pemapurasitiki emaindasitiri. Density iyi inobvumira POM kuti ibudirire mukuramba abrasion uye kugadzikana kwedimensional.
3. Zvinhu zvinokanganisa POM density
Nepo huwandu hwePOM densities hwakati dzikamei, kuwanda kwePOM kunogona kusiyana zvishoma kubva kumugadziri kuenda kumugadziri uye mamiriro ekushandisa kune application mamiriro. Zvinhu zvinokanganisa POM density zvinosanganisira:

Crystallinity: iyo yakakwira crystallinity yePOM zvinhu, iyo inokwirisa density yayo. Yepamusoro crystallinity kazhinji inoreva kuti zvinhu zvine simba remagetsi riri nani uye kupfeka kuramba.
Mafirita uye ekuwedzera: Mune mamwe akakosha maapplication, mafirita kana ekuwedzera anogona kuwedzerwa kunatsiridza kupisa kupisa kana magetsi ePOM. Kuwedzerwa kwezvinhu izvi kunogona kuchinja zvishoma kuwanda kwePOM.
Kugadzirisa: Maitiro akasiyana ekugadzirisa, senge jekiseni kuumba, extrusion moulding, nezvimwewo, inogona kukonzera shanduko shoma mukuwanda kwePOM.

4. POM density yekushandiswa kunoshanda kwekukosha kwe
Mukushandisa zvinoshanda, kunzwisisa "chii chinonzi density yePOM" inogona kubatsira mainjiniya kusarudza chinhu chakakodzera. Yakakwira density kazhinji inoreva kuti zvinhu zvine zvirinani zvemuchina, asi zvinogona zvakare kutungamira mukuwedzera kwehuremu. Mune mamwe maapplication anobata huremu, senge kugadzira zvikamu zvemotokari, chiyero pakati pekuita uye density chingada kuwanikwa.
Iyo density yePOM inokanganisawo maitiro ayo ekugadzirisa uye kugadzikana kwedimensional yechigadzirwa chakapedzwa. Yepamusoro density zvinhu zvinonyanya kugadzikana muchidimbu panguva yekuumba, nepo yakaderera density zvinhu zvingave zvakakodzera zvirinani kune zvimwe zvirerudzo zvinodiwa.
5. Pfupiso
Izvo density yePOM inoenderana nehuwandu hwezvinhu, zvinosanganisira crystallinity, mafirita uye kugadzirisa. Zvizhinji, density yePOM inotangira pa1.41 g/cm³ kusvika 1.43 g/cm³, density inoita kuti zvinhu zvePOM zvinake mumaindasitiri mazhinji. Kunzwisisa uye kushandisa density hunhu hwePOM kwakakosha mukuvandudza mashandiro echigadzirwa uye kugadzirisa maitiro ekugadzira.
Tinovimba kuti kuburikidza nechinyorwa ichi, une kunzwisisa kwakadzama kwe "chii chinonzi density yePOM". Kune avo mainjiniya vanotsvaga kunyatso uye kuita mukusarudza kwezvinhu uye kushandisa, ruzivo urwu ruchabatsira kushandisa zvirinani POM zvinhu.
