Ku lwisana na ku dyuhala ka Ozone ka Lapi ra PTFE ra Mahiselo ya le Henhla

Jiangsu Aokai New Materials, muendli wa xiphurofexinali na fektri ya xihlovo ya lapi ra mahiselo ya le henhla ya PTFE, yi ku nyika xingheniso lexi nga na vuxokoxoko. Lapi ra fiberglass leri pfanganisiweke na polytetrafluoroethylene (PTFE) ri na ku nga tirhi kahle ka tikhemikhali naswona hi ntolovelo ri tisa ku lwisana loku hlamarisaka ka ku dyuhala ka ozone. Hambiswiritano, a yi sirhelelekanga hi ku helela eka ku khuluka ka ozone, naswona matirhelo ya yona hinkwawo ya khumbeka swinene hi nhlayo ya ozone, mahiselo ya ndhawu, nkarhi lowu yaka emahlweni wo hlangana na yona na swin’wana swa le handle.

Hikwalaho ka xivumbeko xa yona xo hlawuleka xa molekhuli, PTFE yi kombisa ku tiya lokukulu ka ozone ehansi ka swiyimo swa ntolovelo. Xihlanganisi xa carbon-fluorine (CF) lexi nga na fluorine hi ku helela xi tinyungubyisa hi matimba ya le henhla swinene ya bond ya kwalomu ka 485 kJ/mol. Hi nkarhi walowo, xivumbeko xa yona xa spiral molecular xi endla xisirhelelo xo enta xa ti athomo ta fluorine, leswi sivela ti oxidants to tiya tofana na ozone ku hlasela carbon-carbon (CC) main molecular chain yale ndzeni.

Hambi swiritano, ozone yinga cinca swinene swihlawulekisi swale henhla swa PTFE naswona yi hlohletela nxaxamelo wa ku cinca ka tikhemikhali na physical. Mindzavisiso yi kombisile leswaku PTFE leyi hlanganaka na ozone yina friction coefficient leyi tlakukeke kwalomu ka kanharhu kutlula eka ndzhawu ya moya lowu tolovelekeke, leswi fambisanaka na swikombiso leswinga erivaleni swa ku onhaka. Leswi swivangiwa ngopfu hi ozone-induced surface oxidation, ku tshoveka ka molecular bond xikan’we naku olova ka swilo.

Hiku hlangana nkarhi woleha na ozone, ngopfu ngopfu ehansi ka swiyimo swo tika swa ntirho swofana na mahiselo yale henhla na nhlayo yale henhla ya ozone, lapi ra mahiselo yale henhla ra PTFE rita hluvuka hakatsongotsongo kusuka eka ku onhaka ka microscopic kuya eka ku tsandzeka ka ntirho wa macroscopic, na swikombiso swokarhi swa ku tsandzeka hindlela leyi landzelaka:

Ku tshoveka ka ti molecular chain na ku onhaka Ozone yi tshoveka ti molecular chains ta CC ta PTFE naswona yi humesa swiphemu leswintsongo swa molecular swofana na carbon tetrafluoride (CF4) na carbonyl fluoride (COF2). Leswi swi endla leswaku kuhunguteka ntiko wa molecule xikan’we naku onhaka ka matirhelo ya xisekelo ya swilo leswi.

Ku pandzeka ka le henhla na ku tshoveka I xiendlakalo xa ku dyuhala lexi twisisekaka swinene. Nchumu lowu wu lahlekeriwa hi ku olova ka le henhla naswona wu humesa ku pandzeka loku hatimaka loku fanaka na network ehansi ka ntshikilelo, ku nga ku pandzeka ka ozone. Lapi ri tiya naswona ri tshoveka, naswona ku dyuhala lokukulu swi ta ya emahlweni swi vanga ku tshoveka ni ku onhaka ka xivumbeko.

Kuhunguteka ka swivumbeko swa michini Ku onhaka ka swilo swiya emahlweni swihunguta matimba ya tensile, elongation eka break, elasticity na swikombiso swin’wana swa nkoka swa michini. Ku tshoveka ka le henhla loku landzelaka, ku tshoveka na kuhungutiwa ka vukulu swita ya emahlweni swi tsanisa ku tiya ka ku onhaka xikan’we naku tiya ka xivumbeko.

Ku onhaka ka swivumbeko swa xivumbeko xa le henhla Ku onhaka ka xivumbeko xa tikhemikhali swi cinca ti parameter ta nkoka to fana na eneji ya le henhla na angle yo tsakama. Ku pandzeka ka microscopic na ti pores leti vumbiweke hiku khuluka ka ozone swita kula hi vukulu, leswinga tsanisa swinene matirhelo yosungula ya ku pfariwa na ku hambanyisa.

Ku tiya ka ozone ka lapi ra PTFE ra mahiselo yale henhla aswi tiveki ntsena hi base material hi yoxe. Mahiselo ya ndzhawu, switandzhaku leswi hlanganisiweke swa ku dyuhala na swiyimo swin’wana swale handle na swona swi tlanga swiphemu swa nkoka eka vutomi bya yona bya vutirheli.

Ku hisa lokukulu ku hatlisisa swinene ku onhaka ka ozone. Ehansi ka swiyimo swa mahiselo yale henhla, oxidation yo tiya ya ozone yi tiyisa ku onhaka ka molecular chain ya PTFE. Hikokwalaho, mpimo wa mahiselo ya nkarhi woleha ya vukorhokeri bya switirhisiwa swa PTFE wu hunguteka swinene kusuka eka 260°C eka moya lowu tolovelekeke kuya eka 200°C–220°C eka tindzhawu ta ozone na gasi yo tiya ya oxidizing.

Kuna mbuyelo wa ku dyuhala lowu tirhisanaka  exikarhi ka ozone na miseve ya ultraviolet. Eka swiyimo swa le handle, ku hlanganisiwa ka miseve ya UV na ozone swi humesa vuyelo byo onha lebyi kurisiweke lebyikulu swinene ku tlula bya nchumu wun’we.

Ku engetela kwalano, khwalithi ya swihumelerisiwa ya hambana kuya hi muendli. Kuhambana eka maendlelo ya vuhumelerisi, ku enta ka coating xikan’we na dizayini ya formula (kufana naku engeteriwa ka ti anti-oxidant stabilizers) swita endla leswaku kuva na swivandla leswinga erivaleni eka ku lwisana na ozone ya nkarhi woleha exikarhi ka switirhisiwa swohambana hambana swa malapi ya mahiselo yale henhla ya PTFE.

Tindlela Leti Humelelaka To Antswisa Ku Lwisana Ka Ozone Ku Dyuhala

1. Engeta ti antioxidants ta xiyimo xale henhla xikan’we na ti light stabilizers eka formula ya PTFE kuva yi khoma ti free radicals xikan’we naku hlwela ku onhaka ka oxidative.

2. Amukela vutshunguri bya ku cinca ka vuandlalo lebyi endleriweke ku endla leyara yo sirhelela leyi tsindziyeleke na ku ndlandlamuxa ku lwisana na ku khuluka ka gasi leyi oxidizing.

3. Ku antswisa swiyimo swa xiviri swa matirhiselo: lawula mahiselo ya ntirho ehansi ka 200°C, naswona papalata vukorhokeri bya nkarhi woleha eka tindzhawu letingana ozone yale henhla xikan’we na radiation ya ultraviolet yotala.

Nkomiso

Lapi ra mahiselo yale henhla ra PTFE ri tirha hiku tiya naswona hindlela ya kahle swinene eka mahiselo ya kamara xikan’we na nhlayo yale hansi ya ozone. Hambiswiritano, ku onhaka ka oxidative, ku pandzeka ka le henhla, ku tshoveka na ku hunguteka loku heleleke ka matirhelo swita humelela eka tindzhawu ta mahiselo yale henhla, ozone yale henhla kumbe UV-coupled harsh environments. Ku lawula mbango loku ringaneleke xikan’we naku cinciwa ka switirhisiwa swinga hunguta hindlela leyinene ku dyuhala naswona swiengetela swinene vutomi bya nkarhi woleha bya vutirheli bya xiendliwa.
