PTFE Tape Salt Spray Resistance & Ngwa mmiri chọrọ

A na-eji teepu okpomọkụ dị elu PTFE eme ihe na gburugburu mmiri - n'elu ikpo okwu ndị dị n'ụsọ osimiri, ụgbọ mmiri, ikuku ikuku n'ụsọ oké osimiri, na mpaghara mmepụta ihe na-ejupụta nnu. Ihe mkpuchi PTFE n'onwe ya na-eguzogide ọgwụ nnu nnu. Agbanyeghị, arụmọrụ teepu ahụ n'ozuzu ya dabere na isi ihe abụọ na-esighị ike: akwa nrapado na nsọtụ nke mkpụrụ osisi fiberglass..

Mgbasa nnu nwere ike banye site na oghere nrapado ma ọ bụ wick n'ime akụkụ fiberglass ekpughere, na-ebute mfu nke nrapado ma ọ bụ corrosion mkpụrụ. Ya mere, inyocha nguzogide ịgba nnu pụtara ịnwale ma nrapado na-ejigide ike njikọ, na-eguzogide mmịnye mmiri, ma na-echekwa ígwè dị n'okpuru ya.

Aokai PTFE na-arụpụta teepu PTFE kwadoro maka ọrụ mmiri. Ntuziaka a na-akọwa ụzọ nnwale ọkọlọtọ, njirisi nnabata, yana ihe achọrọ maka gburugburu nnu-ụrọ dị elu.

Ụzọ nyocha nke nnu maka teepu PTFE

Nnwale ahaziri ahazi na-achọpụta na teepu na-ezute ịdịte aka nke oke mmiri. Usoro a na-ahụkarị bụ nnu nnu na-anọpụ iche (NSS) kwa ISO 9227 ma ọ bụ ASTM B117.

1. Nkwadebe ihe atụ

1. Debe teepu PTFE n'elu ọkọlọtọ igwe nyocha ọkọlọtọ (dịka ọmụmaatụ, SUS304 igwe anaghị agba nchara ma ọ bụ ihe e bu n'obi) site na iji rola.

2. Jiri mmiri na-egbochi mmiri mechie ọnụ ọnụ teepu ahụ ka ọ ghara ịbanye n'ọnụ mmiri nnu na-adịghị mma site n'akụkụ ndị e gbupụrụ. Nke a na-eme ka nrụnye kwesịrị ekwesị ebe echekwara akuku.

3. Kwadebe ihe nlere anya zuru oke maka ule tupu ule, nyocha gachara, na otu njikwa.

2. Ikpughe fogji nnu

• Tinye ihe nlele n'ime ụlọ ịgba nnu na 35ºC, ngwọta NaCl 5%.

• Ogologo oge ule: 96h, 240h, 500h, 1000h , ma ọ bụ dị ka ekwenyere.

• Tụgharịa ogwe ule na 15°–30° site na vetikal maka ọbụna ebe nchekwa nnu nnu.

3. Nyocha mgbe ikpughe (sacha na nkụ)

Ngwa chọrọ maka gburugburu mmiri & Nnu-Nnụnụ dị elu

Maka iji ụwa eme ihe n'ezie na nyiwe dị n'ụsọ osimiri, ụgbọ mmiri, akụrụngwa ike ikuku dị n'ụsọ osimiri, yana mpaghara mmepụta ihe nwere nnukwu nnu nnu, teepu PTFE ga-enwerịrị njirisi siri ike.

1. Nrapado - silicone PSA bụ iwu

• Nkpagide nrụgide silicone: mmịpụta mmiri dị ala, nguzogide nnu nnu pụtara ìhè, ihu igwe. Na-ejigide ike njikọta ogologo oge ma ọ dịghị emebi igwe anaghị agba nchara.

• Acrylic PSA - adabaghị: Ngwa ngwa hydrolyzes, plasticizes, ma na-efunahụ adhesion n'okpuru nnukwu okpomọkụ na nnukwu nnu nnu. E kwesịghị iji acrylic mee ihe na gburugburu mmiri.

2. Substrate na ihu nchebe

• A ghaghị imeju akwa fiberglass nke ọma na PTFE , na-enweghị pinholes. Nke a na-egbochi ntinye nnu site na ime capillary n'akụkụ eriri, nke ga-ebute delamination.

• N'oge echichi, teepu akara na-ekpuchi na n'akụkụ ya na mkpuchi ihu igwe raara onwe ya nye (dịka, dabere na silicone). Nke a na-egbochi ụzọ nnabata nnu nnu - nzọụkwụ kachasị dị mkpa maka ntụkwasị obi ogologo oge.

3. akwadoro indices ịgbasa nnu

• Mgbasa nnu na-anọpụ iche 1000h kacha nta (NSS) na-enweghị ebuli ma ọ bụ ọnya ozugbo.

• 180° bee ike njide ≥80% mgbe 1000h.

• Ọ nweghị corrosion na metal dị n'okpuru (ma ọ bụ nrụrụ corrosion n'ime oke ekwenyere).

• Maka ọnọdụ jọgburu onwe ya (dịka ọmụmaatụ, mpaghara ikuku mmiri nwere okirikiri akọrọ mmiri), 2000h NSS ma ọ bụ nnwale corrosion cyclic (CCT) ka akwadoro.

4. Nkwekọrịta na gburugburu ihe mejupụtara

• Igwe ọkụ dị elu + nnu nnu: Maka mkpuchi ọkpọkọ iyuzucha ma ọ bụ mkpuchi ikuku na-achọpụta okpomọkụ, na-eduzi ule ịka nká jikọtara ọnụ (oke ọkụ + nnu nnu).

• Mkpughe UV: Iji mmiri eme ihe n'èzí chọrọ nguzogide UV - nrapado agaghị etinye nzu ma ọ bụ debond n'okpuru radieshon ultraviolet.

5. Nwụnye na mmezi

• Nkwadebe dị n'elu: degrease zuru oke na ihe jikọrọ ọnụ. A na-atụ aro primer dabara adaba iji kwalite njikọta ihu na igbochi mbanye nnu nnu.

• Nyocha oge niile: Lelee akụkụ teepu n'oge ọrụ maka ọnya ma ọ bụ bee. Dochie teepu dara ngwa ngwa iji gbochie mmebi nrụrụ nke ihe ejikọtara.
