Intangiriro kuri Jiangsu PTFE Abakora Imyenda Yubushyuhe Bwinshi: Ni izihe ngaruka Irrasiyo ya Gamma-Ray igira ku miterere n'imiterere ya PTFE?

Impinduka mu miterere yimiti: Urunigi nyamukuru rwoherejwe na Oxidation

1. Urunigi runini rwo kugabanuka no kugabanuka gukabije muburemere bwa molekile

Imirasire ya gamma isenya neza iminyururu nyamukuru ya CC hamwe na CF kumurongo wa PTFE. Imirasire yimiti yumuriro (G-agaciro) igera kuri 3.0–3.5. Urunigi runini rushobora kubaho no kuri dosiye nkeya cyane, biganisha ku kugabanuka gukabije kwibiro bya molekile. Abakora Imyenda ya PTFE yubushyuhe bwo hejuru muri Jiangsu ifata iyi nkimpamvu nyamukuru itera imikorere mibi.

2. Ibisubizo byubusa na Oxidation

Mugihe kitarimo ogisijeni, radicals yubusa iterwa no gusohora urunigi ihura na recombination cyangwa idahwitse kugirango ibe perfluoroalkanes ngufi. Mu kirere cya aerobic, radicals yubusa ihuza byihuse na ogisijeni ikora radicals ya peroxy, bigatuma habaho urunigi rwongera kuvunika iminyururu ya molekile no kumenyekanisha amatsinda ya nyuma nka acili fluoride na acide karubike. Iyo ihuye nubushuhe, fluoride acili hydrolyze muri acide karubike hanyuma ikarekura fluoride hydrogène ifite ubumara bukabije (HF), ikangiza ibintu cyane.

Impinduka mu miterere ya Leta ihuriweho: Crystallinity na Morphology

1. Crystallinity irazamuka mbere hanyuma igwa

Mugihe gito (mubisanzwe munsi ya 50 kGy), urunigi nyamukuru rutanga ibyiciro bigufi byurunigi bigufi byongerewe imbaraga, bigategura byoroshye muburyo buteganijwe kandi bigatera kwiyongera bidasanzwe muri kristu. Mugihe imishwarara yimishwarara yiyongera, inenge nyinshi nibicuruzwa bitesha agaciro bihagarika imiterere ya kirisiti, hanyuma kristu ikagabanuka.

2. Kurimbuka kwa Lamellar Crystal Imiterere

Nkuko byasesenguwe nabakora imyenda ya PTFE yubushyuhe bwo hejuru muri Jiangsu: Ibisubizo bya WAXS / SAXS byerekana ko imirasire itesha agaciro umwimerere wambere umeze nkigihe kirekire cya lamellar kristal ya PTFE mo kristu ntoya, yacitsemo ibice. Inzira ndende itondekanya imiterere irazimira, iherekejwe na kirisitu yoroheje ya lamellae kandi yongerewe inenge.

Impinduka z'umutungo wa Macroscopique: Kwangirika kwuzuye

1. Ibikoresho bya mashini (Ikimenyetso Cyinshi Cyerekana)

Kurambura kuruhuka bitangira kugabanuka kuri 0.1 kGy gusa mu kirere, kandi bigatakaza hejuru ya 90% hafi ya kGy 1. Ibikoresho bitakaza rwose ubukana kandi bigahinduka bikomeye. Imbaraga zingana zirashobora kuzamuka gato murwego rwambere kubera kwiyongera kwa kristu, hanyuma bigakurikiraho kugabanuka byihuse; modulus ya elastique yiyongera, mugihe kwambara birwanya no kunanirwa byangirika cyane.

2. Ibyiza byubushyuhe

Intungamubiri za kirisitu lamellae hamwe nudusembwa twubatswe bigenda bigabanya buhoro buhoro aho gushonga kuva kuri 327 ° C kugeza munsi ya 310 ° C, hamwe nubushyuhe bwo kugabanuka. Amatsinda adahindagurika kumurongo wa polymer ugabanya cyane ubushyuhe bwambere bwangirika bwumuriro kandi bikangiza ubushyuhe bwumuriro.

3. Ibyiza byamashanyarazi no kugaragara

Amatsinda ya polar (urugero, amatsinda ya karubone) yatangijwe no gutesha agaciro azamura gato dielectric ihoraho no gutakaza dielectric. Ubuso bwibintu buhinduka kuva cyera bugahinduka imvi hanyuma amaherezo bikirabura, biherekejwe no gutakaza cyane ububengerane hamwe na embrittlement.

Ibintu by'ingenzi bigira ingaruka

1. Ibidukikije bya Irrasiyoya (Core variable)

Kwangirika kwikirere birakabije cyane kuruta mu kirere cyangwa mu kirere. Oxygene igira uruhare mu kwiyitirira urunigi nyuma yo gukuramo urunigi, kugwiza imikorere yo kwangirika no kubyara amatsinda yangiza. Ibi bigize imbogamizi yibanze igabanya PTFE ikoreshwa nimirasire.

2. Igipimo Cyuzuye Igipimo

Igipimo cyuzuye cyuzuye kigena urwego rwangiritse muri rusange. Mugihe cyimiterere yindege, irrasi ya dose nkeya itera ingaruka mbi kurenza irrasi ya dose. Oxygene ifite igihe gihagije cyo guhora ikwirakwira imbere yimbere, ikora ibice byimbitse bya okiside igabanuka kandi byangiritse kandi byangiritse, bikarushaho kwihuta gutakaza ibikoresho bya mashini. Kubwibyo, abakora imyenda ya PTFE yubushyuhe bwo hejuru muri Jiangsu banzura ko muri rusange PTFE idakwiriye ibidukikije.

Amakuru yavuzwe haruguru yatanzwe na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba wifuza kumenya ibisobanuro birambuye, ibintu bisabwa hamwe nibisubizo byihariye kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, umukandara wa meshi ya PTFE, umukandara wimashini itagira kashe, umwenda umwe wa PTFE, umukandara wa convoyeur wihanganira ubushyuhe bwinshi hamwe nigitambara cyo hejuru cya fiberglass, nyamuneka twandikire ukoresheje inzira zikurikira:
