Nigute Imiti irwanya PTFE imyenda yo hejuru cyane?

Mu bimera bya shimi, imirongo ya electroplating, hamwe na fabs ya semiconductor, ibikoresho bihora bihura na acide yibasira, alkalis, hamwe nuwashonga. Guhitamo ibikoresho byiza birinda bigira ingaruka kumutekano nibikoresho byubuzima.

PTFE (polytetrafluoroethylene) bakunze kwita 'umwami wa plastiki ' kubera ubudahangarwa bukabije bw’imiti. Ariko 'inert ' ntibisobanura 'udatsindwa ' - niyihe miti ishobora kwangiza? Nigute ubushyuhe hamwe nibitekerezo bigira ingaruka kumikorere yabyo?

Kuri Aokai PTFE , tumaze imyaka twipimisha Imyenda ya PTFE irwanya ibidukikije-nyaburanga. Iyi ngingo isangiye ibyo twabonye kugirango igufashe guhitamo neza.

Imiti PTFE Imyenda Yubushyuhe Bwinshi

1. Acide zikomeye

Imyenda ya PTFE itanga imbaraga nziza kuri:

• Acide ya sulfure (H₂SO₄)

• Acide Nitric (HNO₃)

• Hydrochloric aside (HCl)

• Acide ya fosifori (H₃PO₄)

• Acide nyinshi cyane acide nka aqua regia na aside hydrofluoric (HF)

2. Alkalis ikomeye

Irwanya hydroxide ya sodium (NaOH), hydroxide ya potasiyumu (KOH), amazi ya amoniya (NH₃ · H₂O), nibindi bintu bikomeye bya alkaline.

3. Umuti wumuti

Imiti irwanya imiti myinshi kama, harimo alcool (methanol, Ethanol), ketone (acetone, MEK), hydrocarbone ya aromatic (benzene, toluene, xylene), na lisansi.

4. Ibindi Bikoresho

Ikomeza imikorere ihamye irwanya okiside (urugero, hydrogen peroxide), umunyu (sodium chloride, sodium sulfate), na gaze yangirika (chlorine, hydrogen sulfide).

Imipaka - Imiti yangiza imyenda ya PTFE

Nubwo imiti irwanya imiti, PTFE yubushyuhe bwo hejuru ifite aho igarukira mugihe cy'ubushyuhe bukabije cyangwa mubihe byinshi. Imiti mike yihariye irashobora guteza ibyangiritse nkuko byavuzwe hano:

Byongeye kandi, umwenda wa PTFE ntusabwa gukoreshwa hamwe na:

• Chlorine trifluoride (ClF₃) - gutwika bidatinze

• Oxygene difluoride (OF₂) - reaction yubukazi

• Amazi ya fluor cyangwa gaze (F₂) mubushyuhe bwo hejuru - yibasira PTFE

Ibintu bigira ingaruka kumiti yimiti ya PTFE

Ibintu byinshi bigira ingaruka kumyuka yo kwangirika ya PTFE yubushyuhe bwo hejuru cyane mubikorwa byukuri:

• Ubushyuhe: Imikorere ihamye yimiti ikomeza muri -70 ° C kugeza 260 ° C. Kurwanya bigabanuka kurwanya imiti yihariye ku bushyuhe bukabije.

• Kwibanda: Kwibiza igihe kirekire mubitangazamakuru byangirika cyane bishobora kubangamira imikorere. Kwipimisha kurubuga birasabwa.

• Guhangayikishwa na mashini: Kwangirika kwimiti hamwe no guteranya imashini byihutisha gusaza. Kurinda igipfundikizo cya PTFE ni ngombwa - iyo byangiritse, fiberglass yimbere iba ifite intege nke.

• Igihe cyo kumurika: Kurwanya igihe gito gutandukana biratandukanye no kwibiza.

• Umuvuduko: Umuvuduko mwinshi urashobora guhatira imiti mumyenge ya microscopique cyangwa inenge.

Laboratoire ya Aokai PTFE yerekana ko ubushyuhe-bushingiye ku bushyuhe akenshi budahabwa agaciro. Kurugero, umwenda wa PTFE umara imyaka muri 50% acide sulfurike kuri 100 ° C irashobora kwerekana umweru hejuru mumezi kuri 200 ° C hamwe nuburinganire bumwe. Buri gihe ushyireho umutekano.

Incamake - Imiti irwanya PTFE Imyenda yo hejuru

Kubintu byinshi byinganda zikora inganda, imyenda ya PTFE itanga imikorere yizewe, iramba. Ariko rero, burigihe ugenzure guhuza mubikorwa bifatika - cyane cyane ubushyuhe, kwibanda, hamwe no guhangayika.

Muri make , umwenda wa PTFE ufite ubushyuhe bwo hejuru utanga imbaraga zidasanzwe kuri acide hafi ya zose, alkalis, hamwe nudukoko twangiza umubiri mubikorwa bisanzwe (-70 ° C kugeza 260 ° C). Ibyingenzi bidasanzwe ni ibyuma bya alkali bishongeshejwe hamwe nibikoresho bikomeye bya fluor. Acide ishushe, yibanze cyane nayo isaba kwitonda cyane.

Mubimenyerezo, ubushyuhe, kwibanda, hamwe nubukanishi bukorera hamwe kugirango bigire ingaruka mubuzima. Kubihe bikomeye, turasaba kwipimisha kurubuga cyangwa gukoresha 30-40 ° C yumutekano munsi yubushyuhe ntarengwa.

Ukeneye ubufasha hamwe nibidukikije byimiti? Itsinda rya tekinike rya Aokai PTFE ryakusanyije amakuru yo kwangirika kubitangazamakuru amagana. Twandikire kugirango tuyiyobore cyangwa guhitamo PTFE yashizwemo ibisubizo.

Yatanzwe na Jiangsu Aokai Ibikoresho bishya byikoranabuhanga Co, Ltd.

Kubisobanuro birambuye, ibisobanuro byerekana, hamwe nibisubizo byihariye byibicuruzwa byuzuye birimo imyenda yubushyuhe bwo hejuru bwa PTFE, kaseti yubushyuhe bwo hejuru bwa PTFE, umukandara wa meshi wa PTFE, umukandara udahuza, umwenda umwe wa PTFE, umukandara wa convoyeur wihanganira ubushyuhe hamwe nigitambara cya fiberglass , nyamuneka twandikire:

• Bwana Guo: +86 18944819998

• Bwana Liu: +86 13705266308

Twubahiriza ubunyangamugayo nubunyangamugayo, twihaye gutanga igisubizo kimwe kandi twita kuri serivisi.
