Kuki PTFE Imyenda Yubushyuhe Bwinshi-Imiriro irwanya umuriro? Ni ubuhe buryo bwa Microscopique Flame-Retardant Mechanism?

Jiangsu Aokai Ibikoresho bishya, uyobora uruganda rukora imyenda ya PTFE yubushyuhe bwo hejuru, abisobanura:

Imyenda yubushyuhe bwo hejuru ya PTFE irwanya umuriro cyane mumuriro ufunguye, bitewe ahanini nuburyo bwa molekile hamwe nuburyo bwo kubora bwumuriro wibikoresho byingenzi - polytetrafluoroethylene (PTFE). Ikirangantego cyacyo ntigishobora gushingira ku byongeweho umuriro nk'ibikoresho bisanzwe, ahubwo bituruka ku miterere yacyo ya kimiti ndetse n'imyitwarire idasanzwe yo kubora.

Ibi birashobora kumvikana kuva mu nzego eshatu:

1. Molecular Ikomeye 'Intwaro ': Ingufu Zirenze Zirenze kandi Zirinda

·  Imiyoboro ikomeye ya karubone-fluor (C - F) : molekile ya PTFE igizwe numugongo wumunyururu wa karubone ukikijwe cyane na atome ya fluor. Inkunga ya C - F ni imwe mu miti izwi cyane y’imiti, ifite ingufu zingana na 485 kJ / mol. Ingufu nyinshi cyane (ubushyuhe) zirasabwa kumena, zigakora umurongo wambere wo kwirwanaho.

·  Ingaruka zo gukingira atome ya fluor : Atome nini, zuzuye nabi za fluor zipakiye cyane, zikora nkintwaro nini yuzuye uruziga rwimbere. Iyi bariyeri irinda imiti myinshi (harimo na ogisijeni) kugera kumurongo wa karubone kandi ikabuza cyane reaction ya okiside ikenewe kugirango yaka.

2. Kutabora Kwangirika: Depolymerisation Aho gutwika

·  Gukata urunigi mbere ya okiside : Mugihe cy'ubushyuhe bwo hejuru, karuboni-karubone (C - C) idakomeye cyane muri PTFE gucika mbere ya C - F. Iminyururu ya molekulari itangira kubora mbere yuko ogisijeni ishobora kugira uruhare mubitekerezo.

·  Ibicuruzwa nyamukuru ni monomer : Iyo bimenetse, PTFE ihura cyane na depolymerisation , ikarekura tetrafluoroethylene (C₂F₄) monomers kuva kumutwe. Ibikoresho biva mu kirere aho gutwikwa bikabije birekura ubushyuhe bwinshi na gaze yaka umuriro.

C₂F₄  Ingaruka ya bariyeri ya gazi : gaze ya ituruka kuri depolymerisiyasi iruta umwuka kandi igatura hafi yubuso, igakora gaze ya gazi yigihe gito igabanya umwuka wa ogisijeni kandi igakomeza guhagarika umuriro.

3. Gushyigikira Uruhare rwa Glass Fibre Substrate

Imyenda ya PTFE yubushyuhe bwo hejuru ni ikomatanyirizo ryakozwe mugutwikira PTFE kumyenda y'ibirahure. Fibre fibre ubwayo nikintu kidashobora gukongoka ibintu bidasanzwe. Nka skeleton yubatswe, iremeza ko niyo ubuso bwa PTFE bwakoreshejwe neza munsi yubushyuhe bukabije, ibikoresho ntibishonga cyangwa bitonyanga nka plastiki isukuye, bikomeza ubusugire bwimiterere kandi birinda umuriro gukwirakwira.

Twakagombye gushimangira ko PTFE idakongeza umuriro , ntabwo yaka umuriro. Iyo ishyutswe hejuru yacyo (327 ° C) kandi ikomeza, irabora ikarekura imyuka yubumara. Ubusanzwe irwanya ubushyuhe bwigihe kirekire kugeza kuri 260 ° C kandi igakomeza guhagarara neza muri 300-360 ° C.

Kwangirika mumuriro ufunguye : Iyo uhuye neza numuriro ufunguye (hejuru yubushyuhe bwacyo bwo kubora), urwego rwa PTFE rurangirika, ariko inzira ntabwo itanga ubushyuhe buhagije cyangwa ibicanwa kugirango bikomeze. Ufatanije nikirahure cya fibre fibre, umuriro ntushobora gukwirakwira.

Muri make, imyenda ya PTFE yubushyuhe bwo hejuru ntishobora kwihanganira umuriro kuko ibikoresho byingenzi bya PTFE byakozwe muburyo bwo kurwanya inkongi y'umuriro .Imiyoboro ihambaye y’ingufu zikomeye, inzira zidasanzwe zangirika, hamwe na skeleton ya fibre fibre idashobora gutwikwa hamwe ikora inzitizi ikomeye yumuriro.

Amakuru yavuzwe haruguru atangwa na Jiangsu Aokai Ibikoresho bishya byikoranabuhanga Co, Ltd..

Kubisobanuro birambuye, ibintu byakoreshejwe hamwe nibisubizo byabigenewe byuzuye mubicuruzwa byacu byuzuye - harimo imyenda yubushyuhe bwo hejuru bwa PTFE, kaseti ya PTFE yubushyuhe bwo hejuru, umukandara wa PTFE wubushyuhe bwo hejuru, umukandara utagira kashe kumashini ihuza, umwenda wa PTFE uruhande rumwe, umukandara wa convoyeur wihanganira ubushyuhe bwinshi, imyenda y'ibirahure irwanya ubushyuhe bwinshi nibindi bicuruzwa bifitanye isano - nyamuneka twandikire:

●  Bwana Guo: 18944819998

●  Bwana Liu: 13705266308
