Kurwanya Imiti Kurwanya PTFE Imyenda Yubushyuhe Bwinshi - Ibyo Byihanganira Nibidashoboka

Mu bimera bya shimi, imirongo ya electroplating, hamwe na fabs ya semiconductor, imirongo y'ibikoresho hamwe n'umukandara wa convoyeur bihura nibitero bivuye kumiti ikaze. Imyenda ya PTFE yubushyuhe bwo hejuru (umwenda wa fiberglass ushyizweho na polytetrafluoroethylene) ukunze gusobanurwa neza kubera ubudahangarwa bw’imiti budasanzwe. Ariko 'hafi ya bose ' kurwanya ntabwo 'rusange ' - ibintu bike byibasiye bishobora kubitera, kandi ubushyuhe bugira uruhare runini.

Aokai PTFE yagerageje umwenda wa PTFE kurwanya imiti amagana. Aka gatabo gasobanura icyo kanga, icyo kwirinda, nuburyo ubushyuhe bugira ingaruka kumikorere.

Muri rusange Umwirondoro Wimikorere - Hafi ya Universal Chemical Inertness

Imyenda ya PTFE yubushyuhe bwo hejuru ifite imiti idasanzwe yo kurwanya ruswa, ikaza murwego rwo hejuru rwibikoresho bisanzwe byubuhanga. Uyu mutungo wibanze ukomoka kuri polytetrafluoroethylene yo hanze, igizwe nububiko bukomeye bwa karubone-fluorine (CF) irwanya ibitero byimiti.

Substrate ya fiberglass munsi ntabwo iba inert ya chimique - ariko mugihe cyose igifuniko cya PTFE gikomeje kuba cyiza, umwenda ukora nkibikoresho bya inert. Ku bushyuhe busanzwe bukora, umwenda wa PTFE ukomeza kuba mwiza cyane ugereranije na acide nyinshi zikomeye, alkalis ikomeye, ibishishwa kama, hamwe na okiside.

Urwego runini rwibitangazamakuru birwanya - Ibyo imyenda ya PTFE ishobora gukemura

Ubushyuhe busanzwe bukora, ibintu bikomeza kuba byiza cyane kurwanya aside nyinshi, alkalis ikomeye, ibishishwa kama, hamwe na okiside.

1. Acide ikomeye

Acide yibanze ya sulfurike, aside nitric, aside hydrochloric, aside fosifori, na aqua regia (imvange ya acide nitric na hydrochloric aconga zahabu) - PTFE irabihanganira byose. Nta gutesha agaciro kugaragara.

2. Alkalis ikomeye

Sodium hydroxide (NaOH) hamwe na hydroxide ya potasiyumu (KOH) nta ngaruka mbi bigira ku bushyuhe bwicyumba. Kurwanya bigera no kuri alkaline nyinshi.

3. Umuti wumuti

PTFE ntishobora gukemuka mumashanyarazi yose azwi. Ntabwo izabyimba cyangwa ngo ishonga mugihe ihuye na ketone, alcool, ethers, hydrocarbone, chlorine solver, cyangwa ikindi cyiciro icyo aricyo cyose.

4. Oxidizing agent

Yerekana kwihanganira bihebuje okiside ikomeye nka hydrogen peroxide (H₂O₂) na permanganate.

5. Imitungo yinyongera

• Hydrolysis-irwanya - idatewe namazi cyangwa amavuta

• Ikirere cyihanganira ikirere - UV hamwe no hanze bitera kwangirika gake

• Amavuta yanga kandi adakomeye - ingufu zo hasi zirinda gufatana

• Kwinjiza amazi - neza zeru (<0.01%)

Ibidasanzwe - Imiti yo kwitonda

PTFE ntabwo irwanya isi yose. Ifata numubare muto wimiti ikora cyane mubihe bikabije, bisaba kwitabwaho cyane mugihe cyo gutoranya ibintu.

Aokai PTFE ashimangira ko ibyo bidasanzwe ari gake ariko ni ngombwa kubimenya:

H3: Ibyuma bya alkali

Sodium ya Molten (Na), potasiyumu (K), na lithium (Li) bisenya karuboni-fluor muri PTFE, bigatera kurimbuka burundu. Iri ni ihame ryihishe inyuma ya sodium-naphthalene yo kuvura PTFE.

H3: Ibibyimba bya halogene byikora cyane mubushyuhe bwinshi n'umuvuduko mwinshi

• Chlorine trifluoride (ClF₃)

• Oxygene difluoride (OF₂)

• Gazi ya Fluorine (F₂) hejuru yubushyuhe n'umuvuduko

Ibi birashobora kubyitwaramo cyangwa no gutwika PTFE mubihe bikabije.

H3: Gushonga alkalis ikomeye mubushyuhe bwinshi

Hydroxide ya sodium ya elegitoronike (NaOH) cyangwa hydroxide ya potasiyumu (KOH) hejuru ya 300 ° C yangiza buhoro buhoro PTFE. Ku bushyuhe bwicyumba, nta ngaruka.

H3: Kwibutsa byingenzi - kwangiza gutwika byerekana fiberglass

Imipaka yavuzwe haruguru ikoreshwa gusa hejuru ya PTFE. Niba igifuniko cyashushanijwe, cyangiritse, cyangwa gifite pinholes, substrate ya fiberglass substrate izagaragara. Fiberglass ifite imbaraga zo kurwanya:

• Acide Hydrofluoric (HF) - ishonga vuba fibre yibirahure

• Alkalis ishyushye cyane - itera ikirahure

Niyo mpamvu kubungabunga ubudahangarwa ari ingenzi kuri serivisi yimiti. Kubisabwa birimo HF, tekereza firime nziza ya PTFE.

Ingaruka yubushyuhe kuri Kurwanya Imiti

Ubushyuhe bukora nkikintu gikomeye kigenga imiti irwanya imiti. Mubikorwa byigihe kirekire bya serivise yubushyuhe (mubisanzwe -70 ° C kugeza 260 ° C), imiti ya PTFE ntigihinduka.

Nyamara, ubushyuhe burambye burenga 260 ° C bizaba:

• Buhoro buhoro gabanya ubumara bwa PTFE

• Kora ibikoresho byoroshye kwibasirwa nisuri nibintu bikabije byavuzwe haruguru

• Kwihutisha iyangirika ryumuriro, utere ingingo zintege nke aho igitero cyimiti gishobora gutangirira

Ikizamini cya Aokai PTFE: Kuri 250 ° C ikomeza kugaragara, umwenda wa PTFE ugumana> 90% byimiti irwanya imiti nyuma yiminsi 200. Kuri 280 ° C, imikorere igabanuka cyane mubyumweru.

Kubisabwa hamwe nubushyuhe bwo hejuru (> 260 ° C) hamwe nubushakashatsi bwimiti, baza amakuru ya tekiniki cyangwa ukore ibizamini byihariye.

Incamake - Igihe cyo Guhitamo Imyenda ya PTFE kubidukikije

Aokai PTFE itanga imyenda isize PTFE kugirango isabe ibidukikije. Kubisabwa bisaba guhangana na HF cyangwa imiti ikabije, turasaba kwipimisha mubikorwa byukuri cyangwa gukoresha amanota meza ya PTFE. Twandikire hamwe na chimique yawe yihariye, ubushyuhe, nigihe cyo kwerekana kugirango tugusabe.

Ibi bikoresho bya tekiniki bitangwa na Jiangsu Aokai Ibikoresho bishya byikoranabuhanga Co, Ltd.

Niba ukeneye ibisobanuro birambuye, ibintu bisabwa hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, imikandara ya meshi ya PTFE, imikandara yimashini idahwitse, umwenda wa PTFE utwikiriye ubushyuhe, imikandara itwara ubushyuhe hamwe numuyoboro ukabije wa fiberglass:

• Bwana Guo: +86 18944819998

• Bwana Liu: +86 13705266308

Dushyigikiye amahame ya serivisi yumwuga nubunyangamugayo, kandi twiyemeje rwose gutanga ibisubizo-byose hamwe ninkunga yitonze kubakiriya bose!
