Imyenda ya PTFE isize fiberglass ni ibikoresho byinshi bikozwe mugutera inda ya fiberglass hamwe na polytetrafluoroethylene (PTFE) ikwirakwizwa hanyuma igacumura mubushyuhe bwinshi. Imiterere yacyo irashobora kugabanywamo ibice bibiri: igipfundikizo cya PTFE nigitambara cya fiberglass.
Mubidukikije byangiza imiti, impinduka zimiterere ziterwa nubwoko, kwibanda, hamwe nubushyuhe bwikigereranyo cyangirika, kimwe no kwibasira cyane cyane igifuniko cyangwa substrate. Reka dusuzume iki cyiciro ukurikije uko abakora imyenda ya PTFE isize:
I. Impinduka mu Gipfundikizo cya PTFE: Irahagaze Cyane Mubenshi Mubibazo
PTFE izwi nka 'Umwami wa Plastiki ' kubera imiyoboro ikomeye ya karubone-fluor hamwe nubusembure bukabije bwimiti. Mubidukikije bisanzwe byangirika (harimo guteka aqua regia, acide sulfurike yibanze, aside nitricike yibanze, ibishishwa kama, nibindi), imiterere yumunyururu wa molekuline ntago ihinduka ryimiti. Ariko, mubihe bikabije bikurikira, imiterere izaba yangiritse:
- Impinduka zuburyo: Ibyuma bya alkali bizakuramo atome ya fluor muri PTFE, bitera reaction ya dehydrofluorination. Amatsinda -CF₂- mumurongo wa molekile arasenywa, akora karuboni-karubone inshuro ebyiri (-C = C-) hanyuma biganisha kuri karubone.
- Kugaragara kwa Macroscopique: Igipfundikizo gihinduka kuva amata yera / yoroheje ahinduka umukara cyangwa umukara, atakaza guhinduka, akavunika, na poro. Ibi nibisanzwe byangiza imiti.
2.
- Elemental fluorine (F₂), chlorine trifluoride (ClF₃), hamwe nibindi bisa birashobora kumena umugongo wa karubone-karubone, bigatuma igifuniko kibora.
- Munsi yubushyuhe bwinshi nigitutu, bimwe mubwoko bwa Freon birashobora gutera kubyimba cyane kwa PTFE. Nubwo imiti yimiti idashobora kubaho byanze bikunze, imiterere yumubiri ibabazwa no kugabanuka kwa kristu, kwaguka kwinshi, no gutakaza imbaraga kubera iminyururu ya molekile ihatirwa.
3. Acide Oxidizing ikomeye cyane mubushyuhe bwinshi
- Kwibiza igihe kirekire mumyuka ya acide ya nitric cyangwa acide sulfurike ishushe irashobora guhumeka buhoro buhoro hejuru ya PTFE, ikazana amatsinda ya polar nka karubone na hydroxyl, no kongera ingufu zubutaka. Ariko, ibi ntibikunze kugaragara mubikorwa bisanzwe.
Ingingo y'ingenzi: Kubenshi mubitangazamakuru byinshi byimiti, igifuniko cya PTFE ubwacyo ntabwo cyubatswe 'ntigihinduka. ' Nyamara, ikibazo gikunze kuba mubyukuri ko kidashoboka rwose, ndetse no mumitekerereze yacyo.
II. Impinduka mumyenda ya Fiberglass Base: Iterambere ridakomeye ryibikoresho byose
Ibice byingenzi bigize fiberglass ni dioxyde ya silicon (SiO₂) hamwe na oxyde yicyuma. Iki gice kimaze gukosorwa, imiterere rusange yimyenda yubushyuhe bwo hejuru izasenyuka.
1. Igitero Cyica Acide Hydrofluoric (HF)
- Impinduka zuburyo: HF ikora reaction yihariye na SiO₂: SiO₂ + 4HF → SiF₄↑ + 2H₂O. Felglass skeleton irashonga kandi irazimira.
- Kugaragara kwa Macroscopique: Ubuso bwigitambara butakaza imbaraga byihuse, bihinduka nkuruhu rworoshye hasigaye gusa igifuniko gisigaye, gushwanyagurika byoroshye gukurura, hamwe no gutandukana kwinshi hagati yigitereko na substrate. Nibintu biteye ubwoba cyane byangirika kubikoresho byibirahure-fibre. Igihe cyose hari ibinogo bitwikiriye cyangwa bigaragaye, ibyangiritse birababaje.
2. Gutinda buhoro na Alkalis ikomeye (cyane cyane alkalis zishyushye)
- Impinduka zuburyo: OH⁻ ion zimena imigozi ya siloxane (-Si-O-Si-) murusobe rwibirahure, ikora silicates zishonga. Ubuso bwa fibre burahinduka kuva muburyo bworoshye kugeza bubi, hamwe nibyobo byacitse nibice bigaragara, diameter ya fibre iranyerera, amaherezo ikavunika.
- Kugaragara kwa Macroscopique: Imbaraga zikomeza kugabanuka, umwenda ucika intege, kandi iyo wunamye, fibre zavunitse zisohoka mu mwenda, bigatuma igifuniko kimeneka kandi kigashonga.
- Impinduka zubatswe: Acide isanzwe (aside hydrochloric, aside sulfurike, nibindi) nibyiza cyane gusohora ibice bitari silika (nka aluminium, okiside ya calcium, nibindi) biva muri fiberglass, hasigara ahanini skeleton ya silika. Iyi nzira izwi cyane nka 'leaching, ' ikora imiterere ya microporome hejuru ya fibre.
- Kugaragara kwa Macroscopique: Umwenda urakomera kandi ugacika intege, hamwe nimpinduka zo kugabanuka, nubwo imiterere rusange ishobora kugumaho. Imbaraga zigabanuka kubera guhangayikishwa cyane.
III. Impinduka kuri Interineti Ihuza: Kunanirwa guhishe
Ibidukikije bya shimi ntibibasira imbonankubone ahubwo byinjira kuva kumpande cyangwa binyuze muri micro-nenge.
. Ibicuruzwa byitwara neza cyangwa ibintu byinjira mumazi birundanya kuri interineti, bikabyara umuvuduko wa osmotic, bigatuma igifuniko cya PTFE gihinduka kandi kigatandukana na fibre yububiko bwa fibre.
- Gucika intege za Stress: Imyenda yubushyuhe bwo hejuru irahangayitse mugihe cyo kuyikoresha. Kwangirika kwa fiberglass hamwe nibitangazamakuru bya chimique (cyane cyane alkalis ikomeye) ikorana hamwe nihungabana ryimashini, bigatuma ibice bikwirakwira vuba mugihe cyerekezo cya fibre radiyo, biganisha kumeneka gitunguranye hamwe na morfologiya isukuye-ivunika.
Mu bidukikije byangiza imiti, impinduka zuburyo bwimyenda ya fibre yububiko bwa PTFE irashobora kuvugwa muri make nka: 'Umwami wa Plastike ' igifuniko gikomeza kuba gihagaze neza nkumusozi, mugihe umwenda wibanze wa fiberglass - umaze kwinjira cyangwa gutera - uhinduka agatsinsino ka Achilles, bigatera gusenyuka kwa skeleti, gutandukana kwimbere, hamwe nibintu byose bisenyuka bivuye imbere.
