Kedu ihe na-egbochi ndụ ọrụ nke akwa PTFE dị elu?

PTFE akwa okpomọkụ dị elu na-adịgide adịgide - ọ nwere ike iguzogide ọtụtụ afọ nke okpomọkụ, mkpughe kemịkalụ, na ọrụ na-adịghị mma. Ma n'ikpeazụ, ọ na-ada. Ajụjụ bụ: gịnị na-eme ka ọ daa, oleekwa otú ị ga-esi mee ka ọ dị ogologo?

Azịza ya gụnyere ihe dị iche iche isii: okpomọkụ (nke kachasị), nrụgide n'ibu, gburugburu ebe obibi kemịkalụ, omume nhicha, ọnọdụ nchekwa, na àgwà mbụ nke ákwà ahụ n'onwe ya.

Aokai PTFE enyochala ọdịda ubi gafee ọtụtụ puku ngwa. N'okpuru ebe a, anyị na-akọwa ihe ọ bụla, otu esi amata akara ịdọ aka ná ntị mbụ, yana ihe ị nwere ike ime iji gbasaa ndụ ọrụ.

Okpomọkụ - Onye na-egbu onye mbụ

PTFE nwere ike ijikwa oke okpomọkụ, mana naanị ruo otu isi. Gafee ebe ahụ, nbibi na-abawanye ngwa ngwa.

1. Na-aga n'ihu n'elu-okpomọkụ ọrụ

Oke kachasị ogologo oge na-aga n'ihu na-arụ ọrụ nke PTFE bụ ihe dịka 260 ° C. A na-anabata njem nlegharị anya dị mkpirikpi ruo 300°C, mana ogologo oge ikpughe karịa 260°C na-akpata:

• Yellowing na ebrittlement nke mkpuchi

• Ọnwụ nke ihe na-abụghị osisi

• Nbibi (karịa 400 Celsius C, na-ahapụ gas na-egbu egbu)

• Mbelata ike igwe

Nleba anya n'ubi: eriri ebufe PTFE na-agba na 280°C kama 250°C nwere ike ịdịru naanị ọnwa 6 kama afọ 3.

2. Kwuo ngwa ngwa na ikpo ọkụ ugboro ugboro (ọkụ ọkụ)

PTFE mkpuchi na fiberglass mkpụrụ nwere ọnụọgụ dị iche iche nke mgbasawanye thermal. Mgbe ákwà ahụ na-ekpo ọkụ ma dị jụụ ngwa ngwa na ugboro ugboro:

• Ihe mkpuchi ahụ na-agbasawanye na nkwekọrịta na ọnụego dị iche iche karịa eriri iko

• Nke a na-akpata delamination n'etiti n'ígwé → cracks, blisters, na nkewa

• Karịsịa siri ike n'akụkụ akwa na gburugburu ihe nrụnye igwe

Mgbochi: Zenarị mgbanwe okpomọkụ na mberede. Ebe ịnya igwe na-ekpo ọkụ na-agaghị ekwe omume, họrọ akwa nwere mma nrapado (ngwọta ihu igwe kwesịrị ekwesị) ma zere mpịaji dị nkọ.

Nchegbu Mechanical – Ehulata, erughị ala, na abrasion

Fiberglass mkpuchi PTFE siri ike na mgbakasị ahụ mana adịghị ike na-ehulata ugboro ugboro. Nchekasị n'ọrụ igwe na-abụkarị ihe ọdịda nke abụọ na-ebutekarị mgbe oke okpomọkụ gasịrị.

1. Na-ehulata ugboro ugboro na creasing

Ọ bụ ezie na akwa PTFE na-agbanwe agbanwe, mkpụrụ osisi fiberglass nwere nguzogide mgbanwe na-adịghị mma. Mpịakọta mgbe niile ma ọ bụ creases na-adịgide adịgide n'otu ọnọdụ ga-:

• Gbajie eriri iko

• Gbawaa mkpuchi PTFE

• Mepụta akara crease ọcha na-enweghị mgbagha na-agbasa ngwa ngwa n'ime anya mmiri

Mgbochi: Jiri radius na-ehulata kacha ukwuu. Maka ngwa na-achọ mpịachi ugboro ugboro (dịka ọmụmaatụ, ákwà mgbochi mbughari), tụlee ọkwa dị gịrịgịrị ma ọ bụ akwa PTFE nke aramid gbasiri ike.

2. Oke ike ike

Mgbe ejiri ya dị ka eriri ebufe, oke ụjọ na-ebute:

• Ike ọgwụgwụ fiber (eriri iko ji nwayọọ nwayọọ na-agbaji n'okpuru ibu na-adịgide adịgide)

• Nrụrụ mkpuchi mkpuchi (agbatị na ịcha)

• Ịdị nwayọọ nwayọọ nwayọọ na-akwawa

Mgbochi: Soro oke ọgbaghara nke onye nrụpụta tụrụ aro. Maka ndị na-ebufe ogologo oge, jiri akwa nwere ike dị elu (dịka ọmụmaatụ, akwa akwa ma ọ bụ akwa sara mbara).

3. Esemokwu na-aga n'ihu na abrasion

Mmekọrịta ogologo oge na-amị amị na ihe siri ike ma ọ bụ ihe siri ike na-eyi mkpuchi PTFE. Ozugbo mkpuchi ahụ kwụsịrị, eriri fiberglass ahụ ekpughere na-akụda ma daa ngwa ngwa.

Mgbochi: Maka ngwa ndị na-amị amị (dịka ọmụmaatụ, okporo ụzọ ntuziaka), jiri akara PTFE juputara na nguzogide abrasion ka mma ma ọ bụ tinye akwa akwa. Mmanya mgbe niile (mmanụ silicone ọkwa nri) nwekwara ike ibelata esemokwu.

Mpaghara Chemical - Ọ bụghị Chemicals niile dị mma

PTFE bụ ama ama inert, mana ụfọdụ kemịkalụ na-awakpo ya - ọkachasị na oke okpomọkụ.

1. Strong oxidants na arụ ọrụ ọla

N'ebe okpomọkụ dị elu, ịkpọtụrụ ndị a ga-emebi PTFE ozugbo:

• Ọla alkali gbazere (sodium, potassium) - mbibi zuru oke

• Chlorine trifluoride, fluorine gas - mmeghachi omume ime ihe ike

• Acid siri ike gbadoro anya nke ukwuu - mbuze nwayọ nwayọ na oke okpomọkụ

Mgbochi: Zere kemịkalụ ndị a kpamkpam. Maka ngwa ndị metụtara oxidizers ike, jiri ihe dị iche ma ọ bụ hụ na akwa PTFE adịghị ekpughe ozugbo.

2. Ihe ndị nwere silicon na ntinye griiz

Ịbanye ogologo oge nke mmanụ na-enye okpomọkụ dị elu, ihe ndị na-ahapụ silicone, ma ọ bụ griiz nri n'ime micro-pores nke mkpuchi nwere ike ime:

• Carbonization na coking n'okpuru mkpuchi

• Blisting na delamination mgbe ọkụ

Mgbochi: Na-ehicha akwa ahụ mgbe niile tupu ihe ndị fọdụrụ enwee oge ịbanye. Maka mkpughe mmanụ dị arọ, họrọ mkpụrụ osisi denser (ọnụọgụ eri dị elu).

Nchacha na njikwa - Otu esi ehicha ihe

Nhicha na-ezighi ezi bụ ihe a na-ahụkarị, nke a na-egbochi ya na-akpata ọdịda akaghi aka.

1. Na-ekpochapụ ihe ndị fọdụrụ na carbonized

A na-ejikarị shọvel ọla, ajị anụ, ma ọ bụ akwa akwa akwa akwachapụ nri siri ike carbonized nri, nrapado, ink ma ọ bụ ihe nkwụnye ego ndị ọzọ. Ngwá ọrụ ndị a na-ekpocha mkpuchi PTFE . Ozugbo a kpụchara ya, ihe onwunwe na-abụghị osisi na-efunahụ ya, na mmetọ na-arapara n'ụzọ dị mfe - na-emepụta usoro ọjọọ.

Usoro ziri ezi: Jiri ihe mkpocha plastik, spatulas osisi, ma ọ bụ brush naịlọn dị nro. Maka ihe fọdụrụ nke isi ike, gbanye ma ọ bụ uzuoku dị nro tupu ihichapụ.

2. Ndị na-ehicha ihe na-adịghị mma

PTFE n'onwe ya bụ kemịkalụ inert, mana enwere ike ịwakpo ihe mkpuchi mkpuchi (maka teepu) ma ọ bụ interface n'etiti mkpuchi na mkpụrụ. Ịbanye ogologo oge na:

• Ihe mgbaze siri ike (ndị na-ewepụ agba, acetone)

• Ihe nchacha pH dị elu (bleach, caustic cleaners)

…nwere ike banye site na pinholes wee mebie njikọ dị n'etiti mkpuchi na mkpụrụ.

Usoro ziri ezi: Jiri ncha efere dị nro, mmiri ọkụ, ma ọ bụ ihe nchacha ọkwa nri. Sachaa nke ọma.

Nchekwa na ọnọdụ gburugburu ebe obibi

Ọbụna mgbe ejighị ya mee ihe, akwa PTFE nwere ike imebi ma ọ bụrụ na echekwara ya n'ụzọ na-ekwesịghị ekwesị.

1. Ogologo oge ikpughe UV

PTFE nwere ezigbo nguzogide ihu igwe, mana ikpughe ogologo oge na UV dị n'èzí ga-eme ka:

• Nke nta nke nta n'elu ịka nká

• Nzu (ọcha ntụ ntụ n'elu)

• Ewelatala ike ntakiri

Mgbochi: Maka ngwa n'èzí, họrọ akara ule UV kwụsiri ike. Maka akwa akwa echekwara, debe ya na ebe gbara ọchịchịrị, kpuchie.

2. Dampness na mildew

Ọ bụrụ na mkpuchi ahụ mebiri emebi, mmiri na-abanye na oghere fiberglass ma belata ike eriri. Acids nke ihe mkpofu nri na-adị nro na-emepụta na-emebikwa ihe njikọ ahụ.

Mgbochi: Chekwaa ákwà na ebe akọrọ. Hichaa tupu nchekwa. Ahapụla ákwà ruru unyi ka akpọchiela ya ruo ọnwa.

3. Nchekwa na-ezighị ezi

• Mpịakọta ogologo oge n'okpuru nrụgide dị arọ na-emepụta creases na-adịgide adịgide (isi ihe ọdịda akaghi aka).

• Nchekwa n'akụkụ ebe okpomọkụ dị nso (ọkpụkpọ uzuoku, oven) na-akpata ịka nká okpomọkụ.

Nchekwa ziri ezi: Nyefee akwa akwa na isi, chekwaa na kwụ ọtọ ma ọ bụrụ na ọ ga-ekwe omume, na oyi (10-30ºC), nkụ (<60% RH), ebe gbara ọchịchịrị.

Ogo nrụpụta - Ị nweta ihe ị na-akwụ

Ọ bụghị ihe niile PTFE ka a na-eme otu ihe. Ọdịiche dị mma na-emetụta ndụ ọrụ nke ukwuu.

1. mkpuchi mkpuchi na ịdị n'otu

Ọkpụrụkpụ mkpuchi ezughi oke, pinholes, ikuku ikuku, ma ọ bụ impregnation na sintering na-adịghị mma ga-ebelata ndụ ọrụ nke ukwuu. Njirimara ngwaahịa dị oke mma:

• Ihe mkpuchi zuru oke nke eriri iko

• Adhesion siri ike n'etiti mkpuchi na mkpụrụ

• Enweghị pinholes ma ọ bụ oghere

• Nguzogide ike ọgwụgwụ dị elu

2. Substrate ụdị

Ọdịdị akwa ákwà, dayameta filament, na ịdị arọ nke ákwà fiberglass na-ekpebi ịrụ ọrụ ya. Uwe dị nro ma ọ bụ nnukwu ntupu na-adịghị mma maka ọnọdụ ọrụ na-aka nká ngwa ngwa.

Aokai PTFE na-eji mkpụrụ osisi fiberglass adịchaghị mma nwere njupụta akwa akwa na njupụta PTFE zuru oke. Anyị na-enye data teknuzu na ike tensile, ọkpụrụkpụ mkpuchi na ọnụ ọgụgụ pinhole.

Nchịkọta - Otu esi eme ka ndụ ọrụ PTFE dịkwuo elu

Aokai PTFE na-arụpụta PTFE akwa okpomọkụ na ụkpụrụ dị elu. Anyị nwere ike inyere gị aka ịhọrọ ọkwa ziri ezi, ọkpụrụkpụ na akpa maka ngwa gị iji bulie ndụ ọrụ.
