Chii chinonzi dimensional kugadzikana kweinjiniya mapurasitiki?

August 05, 2024
Ndeipi dimensional kugadzikana kweinjiniya mapurasitiki?
Low IQ: Warping, deformation, haigone kuiswa, kupaza, kunaka, uye pfungwa dzinotevera, uye dzinotevera nhanhatu pfungwa ......
High IQ: Injiniya Purasitiki kubva kune zvikamu zvekugadzirisa, magungano ekunyorera maitiro, nekuda kwekugadzirisa, zvakateerana nemamiriro ekunze ehupenyu hwese, icho chigadzirwa kubva kune izvo zvinyorwa kune zvikamu, kungave basa kushanda kwakanaka. Iyo inonyanya kukanganiswa nekugadzikana kwedare ndeye saizi yechikamu, nekuda kwekunyanyisa kusununguka kana kwakanyanyisa tembiricha, zvichikonzerwa nekuwedzera kwekunyama kana kubvumirana.
Uyezve, kunyangwe kana chikamu chisiri pachena kune vanonyanya kuomesesa nzvimbo, apo zvikamu zvechisimba zvakanyanyisa, maitiro acho anoiswa pasi pekunetseka kukuru kwekunetseka! Saka, zvakakosha kufunga nezvekugadzikana kwakapetwa kwezvinyorwa.

Maitiro ekuongorora iyo dimensional kugadzikana kweinjiniya mapurasitiki?
Inogona kutongwa kubva pane zvinotevera zvinhu:
Coefficient yekuwedzera kwekunyora Iyo yakaderera cte inoreva kuti zvinyorwa zvine zvishoma zvekupfeka shanduko kana tembiricha ichichinja. Nekuda kwechimiro chavo chemakemikari, zvinhu zvepurasitiki zvichawedzera uye chibvumirano chinyoka kune dzakasiyana madhigirii. Shanduko iyi muzvikamu zvekunyama zvinogona kutungamira kune yakakodzera uye clearance matambudziko uye inogona kunetesa michina yezvinyorwa zvekushandisa nguva nenguva.
heat expansion and cold contraction
Kubata kwemvura : Engineering purassics kuwedzera kana ivo vachitora mvura, iyo inogona kutungamira mukuchinja kwekuchinja. Mapurasitiki akasiyana ane akasiyana emvura ekunyora. Mapurasitiki ane yakadzika mvura yekushambadzira ine mashoma mashoma shanduko munzvimbo dzakanyorova uye saka zvakanyanyisa kugadzikana. Uye zvakare, mvura yekunyura inodzora zvimwe zvinhu zvezvinhu, sekusaita kwemagetsi uye nemuchina simba.
Low shrinkage, low water absorption LCP in pr
Mukutarisana nenyama yezvakatipoteredza, kana kutsungirira nekureba kwenguva refu, kunyorova kana kufumura kune zvakasikwa nharaunda, zvakadai sekufunga zvikamu zvepurasitiki mukutenderera kwehupenyu hwayo hwekunyengera, pamwe neiyo kusvinuka uye tembiricha yemanyoro. Semuenzaniso, Nylon PA6, PA.6 Nyore ku hydrolyze. Nepo midziyo senge ppo, peek, lcp ine yakaderera mvura yekunyudza, yakarova zvakanyanya, isa mumvura kana kuomarara.
PPO in water treatment wet environment applic
Kushushikana Kwemukati: Kushungurudzika kwemukati kunogadzirwa panguva yekukura kana kuumbwa kunogona kukanganisa kugadzikana kwezvinyorwa, kugadzirisa izvo, kupaza, kuchibvisa pasi zuva rinotevera, uye mune zvimwe zviitiko kunyangwe zvakanyanyisa, kupwanya mushure mekutakura. Kushungurudzika kwemukati kunogona kukonzera iyo zvinyorwa kushomeka kana kurwadzisa panguva yekutonhora. Izvi zvinodaro nekuti mapurasitiki mamorasitoles anotonhorera kubva kunze mairi
Internal stress cracking of ABS parts
Crystallinity: Iyo dimensional kugadzikana kweiyo hafu-crystalline mapurasitiki akadai sePP, PA6, uye POM inofemerwa nekuchema kwavo. Yakakwira Crystallinity inowanzoguma nekuderera kwehuwandu hwekuwedzera kwekuwedzera uye kukwirira kwakakwirira. Amorphous plastics such as PC, PMMA, PPE, PEI usually have better dimensional stability because of their lower coefficient of thermal expansion.
Application of PC fiber reinforcement in cell
Vafereya uye Modifiers: Kuwedzera mafirita akadai segirazi machira uye carbon felers inogona kuvandudza zvakanyanya kugadzikana kwezvinhu. Modifiers akadai sedzemalilozants, hot stabilizers, etc.
Kugadzirisa mamiriro: tembiricha, kumanikidzwa uye kutonhora uye kuraira kwekunyora kana kuumbwa maitiro kunogona kukanganisa kugadzikana kwechigadzirwa chekupedzisira. Optimizing proceting parameter inogona kuderedza kushushikana kwemukati uye kugadzirisa kudzikisira kwakadzikira.
Injection molding process parameter adjustmen
Mamiriro ekunze: Mumamiriro ekunze akasiyana, humidity, kunze, oiri, doro uye zvimwe zvinhu zvemhoteredzo. Zvepanyama uye zvemakemikari zvivakwa zvezvinhu zvinoshanda mumamiriro ezvinhu akanyanyisa, sarudza kupokana, zvakakwirira uye zvakaderera kupisa kupesana, hydrolysis kurwisa uye zvimwe zvivakwa zveinjiniya zvekushandisa.
Maitiro ekuedza zvakadzama kugadzikana kwemapurasitiki?
Dimensional Shanduko Muedzo (DCC): Kuyera shanduko yedanho rezvinyorwa pasi pemamiriro akasiyana uye manyoro emamiriro ezvinhu.
Kuongorora kweTremomekical (Tma): Matanho ekuchinja kwemukati kwechinhu panguva yekupisa.
Kusiyanisa kuongorora Calorimetry (DSC): Inoshandiswa kuongorora crystallinity uye inonyungudika pfungwa yezvinhu, zvisina kunanga kuratidza kudzikama.
Mvura inowedzera bvunzo (wat): kuongorora iyo mvura yekubvisa uye shanduko yezvinhu zvemagetsi pasi pemamiriro akasiyana ezvinomarara.
Kuburikidza nekuongororwa pamusoro peJunastiki Jun, iwe unofanirwa kuve nekunzwisisa kwekutanga kwekunyorwa kwezvinhu zvemapurasitiki uye zvakatipoteredza, kuitira kuti ufunge kusarudza maitiro ekusarudza zvinhu. Akadai sekusimbisa zvikamu zvinoda kuti saizi yezvinhu yakagadzikana zvakanyanya, nekuti saizi yekusaziva inogona kutungamira kuLeage. Kune dzimwe nhengo dzinoda kugara dzakanatswa ne steam, makemikari kana tembiricha yakanyanya tembiricha, ingave yakaremara nekuda kwemvura, kupokana. Chete chojaya chete, process tekinoroji, kuwedzera dhizaini yekugadzikana kweinjiniya mapurasitiki, kukwanisa kuvaka saizi diki, kukanganisa kwakasimba kwakasimba, sekubatana kwemagetsi uye zvigadziko zvemagetsi.
Tora Zvakaomarara, Nei usingasarudze simbi?
Deredza Uremu: Purasitiki Special Gravity mwenje, muEerospace, emagetsi emagetsi anokwanisa kuvandudza mafuta ekuita mafuta uye kuderedza emission.
Yakaderedzwa mitengo: Yakaderedzwa yekugadzirisa mari inoenzaniswa nesimbi mune yakakwirira vhoriyamu kugadzirwa.
Dhizaini yekuchinjika: Plastics inogona kuiswa jekiseni yakaumbwa, inobuda, uye yakaumbwa nenzira dzakasiyana siyana, dzinopa rusununguko rukuru.
Kemical Resistance: Plastics kazhinji ine yakanaka kurwisa, mukana wakakura wezvikamu zvinoshandiswa munzvimbo dzine hutsinye.
Pfeka kupokana, kushungurudzika uye kuisimbisira: mapurasitiki ane mukana wakajeka mukupokana uye uine mukana wekusimbisa mishonga uye zvimwe zvinoshandiswa nemidziyo yemagetsi uye zvimwe zvekushandisa magetsi zvinodikanwa.
Kurerutsa kwekugadzirisa
Naizvozvo, kuti uongorore zvakakwana kugadzikana kwepurasitiki yeinjiniya, akati wandei zvinhu zviri pamusoro zvinofanirwa kutariswa uye kusimbiswa kuburikidza nekuedzwa kwekuedza. Zvekushandisa zvakanyatsoitika, zvimwe zvinoratidza zviratidzo zvezvinyorwa, zvakadai sesimba, zvakaoma, kupokana kwemakemikari, etc., zvakare zvinoda kufungwa kuti uve nechokwadi chekuti zvinhu zvakakodzera kwazvo zvinosarudzwa.
