Ozone Aging Resistance nke PTFE akwa okpomọkụ dị elu

Jiangsu Aokai New Materials, onye na-emepụta ọkachamara na isi iyi nke akwa akwa okpomọkụ PTFE, na-enye gị nkọwa zuru ezu. Polytetrafluoroethylene (PTFE) akwa fiberglass mkpuchi nwere njirimara kemịkalụ kemịkalụ mara mma ma na-enyefe nguzogide ozone pụtara ìhè. Otú ọ dị, ọ naghị egbochi ya kpam kpam site na ozize ozone, na ọrụ ya n'ozuzu ya na-emetụta nke ukwuu site na ntinye ozone, ọnọdụ okpomọkụ, oge ikpughe oge na ihe ndị ọzọ dịpụrụ adịpụ.

N'ihi usoro ihe omimi ya pụrụ iche, PTFE na-egosipụta nguzogide ozone siri ike n'okpuru ọnọdụ ọkọlọtọ. Njikọ carbon-fluorine zuru ezu (CF) na-etu ọnụ ike njikọ dị elu nke ihe dịka 485 kJ/mol. Ka ọ dị ugbu a, usoro ihe omimi ya na-eme ka ọta nchebe siri ike nke atom fluorine, na-egbochi oxidants siri ike dị ka ozone ịwakpo eriri carbon-carbon (CC) nke dị n'ime.

Ka o sina dị, ozone nwere ike gbanwee njirimara elu nke PTFE ma kpalite usoro mgbanwe kemịkalụ na nke anụ ahụ. Nnyocha egosiwo na PTFE kpughere ozone nwere ọnụọgụ esemokwu dị ihe dị ka okpukpu atọ dị elu karịa nke ahụ na gburugburu ikuku nkịtị, tinyere akara ngosi doro anya. Nke a na-ebutekarị site na ozone na-ebute oxidation elu, mgbaji nke njikọ molecular na ime nro.

Site na ikpughe ozone ogologo oge, karịsịa n'okpuru ọnọdụ ọrụ siri ike dị ka okpomọkụ dị elu na elu ozone, akwa akwa okpomọkụ nke PTFE ga-eji nwayọọ nwayọọ malite site na microscopic mebiri na ọdịda ọrụ macroscopic, na-egosipụta ọdịda ọdịda dị ka ndị a:

Njiji nke yinye molekụla na mbibi ozone na-agbaji agbụ molekụla CC nke PTFE ma mepụta obere iberibe molekụla dị ka carbon tetrafluoride (CF₄) na carbonyl fluoride (COF₂). Nke a na-eduga n'ịbelata ịdị arọ molekụla yana nbibi ọrụ nke ihe onwunwe.

N'elu ihu mgbawa na embrittlement Ọ bụ ihe kacha pụta ìhè ịka nká. Ihe na-efunahụ mgbanwe elu ma na-emepụta netwọk-dị ka mgbawa na-egbuke egbuke n'okpuru nrụgide, ya bụ ozone cracking. Uwe ahụ na-esi ike ma na-agbaji agbaji, na ịka nká siri ike ga-eme ka ọkpụkpụ na-emebi emebi na nhazi.

Ọdịda na akụrụngwa arụrụ arụ Mmebi ihe na-aga n'ihu na-ebelata ike tensile, elongation na nkwụsịtụ, nkwụ na ihe ndị ọzọ na-egosi n'ibu. Mkpụcha elu elu nke na-esote, mkpochapụ na mbelata ọkpụrụkpụ ga-eme ka ike gwụ ike eyi na nkwụsi ike nhazi.

Mbibi nke ihe nhazi elu nke kemịkalụ structural mebiri na-agbanwe isi ihe dị ka ike elu na akụkụ wetting. Ihe mgbawa a na-ahụ anya na oghere nke ozone na-emebi emebi ga-agbasa n'ogo, na-ebelata ike nke mbụ akara na ịrụ ọrụ ikewapụ.

Mgbochi ozone nke akwa akwa okpomọkụ dị elu PTFE abụghị naanị ihe ndabere nke onwe ya kpebisiri ike. Ọnọdụ ihu igwe, mmetụta ịka nká jikọtara ọnụ na ọnọdụ mpụga ndị ọzọ na-arụkwa ọrụ dị mkpa na ndụ ọrụ ya.

Okpomọkụ dị elu na-eme ka mmebi ozone dịkwuo elu. N'okpuru ọnọdụ okpomọkụ dị elu, oxidation siri ike nke ozone na-eme ka mmebi nke yinye molekụla dịkwuo elu nke PTFE. Ya mere, ogologo oge ọrụ okpomọkụ ịgba nke PTFE ngwaahịa tụlee sharply si 260 ℃ na ot ikuku na 200 ℃-220 ℃ na ozone na ike oxidizing gas gburugburu.

Enwere mmetụta ịka nká synergistic  n'etiti ozone na ụzarị ultraviolet. N'ọnọdụ dị n'èzí, nchikota nke radieshon UV na ozone na-emepụta mmetụta mbibi gbasiri ike karịa nke otu ihe.

Na mgbakwunye, ogo ngwaahịa dịgasị iche site na onye nrụpụta. Ọdịiche na mmepụta usoro, mkpuchi ọkpụrụkpụ na usoro imewe (dị ka mgbakwunye na nke mgbochi oxidant stabilizers) ga-eduga doro anya gaps na ogologo oge ozone iguzogide n'etiti dị iche iche PTFE elu-okpomọkụ ákwà ngwaahịa.
