Nibihe Bikoresho Bishobora Kwangiriza PTFE Imyenda Yubushyuhe Bwinshi?

PTFE izwi cyane kubera kutagira imiti - bakunze kwita 'Umwami wa Plastiki. ' Irwanya aside hafi ya zose, alkalis, hamwe n’umuti ku bushyuhe bwicyumba. Nyamara, 'hafi ya byose ' ntabwo 'byose. ' Mubihe bikabije - ubushyuhe bwinshi, ubushyuhe bwinshi, cyangwa mumashanyarazi - imiti imwe n'imwe irashobora gutera PTFE. Kandi niyo PTFE ubwayo irokoka, substrate ya fiberglass substrate irashobora kwibasirwa mugihe igifuniko gifite inenge.

Gusobanukirwa izo mbogamizi ningirakamaro muguhitamo umwenda wa PTFE mubidukikije bikaze.

Aokai PTFE yagerageje imyenda isize PTFE kurwanya imiti ikaze. Aka gatabo gasobanura icyangiza PTFE mu buryo butaziguye, ibitero bya fiberglass substrate, nuburyo bwo kwirinda gutsindwa.

Uburyo Ruswa ibaho - Uburyo bubiri

Imyenda ya PTFE yubushyuhe bwo hejuru igizwe nibice bibiri: igipfunyika cya PTFE (inanutse, idafite inkoni, inert ya chimique) hamwe na fiberglass substrate (itanga imbaraga ariko ishobora kwibasirwa nimiti imwe n'imwe). Ruswa ibaho muburyo bubiri:

1. Isuri itaziguye ya PTFE

Ibi bibaho gusa mubihe bikabije - ubushyuhe bwinshi, kwibanda cyane, cyangwa mumashanyarazi. Ku bushyuhe bwicyumba, PTFE ntakingira indwara yibasiye.

2. Kwangirika kwa fiberglass substrate ikoresheje inenge

Imiti yinjira muri pinholes, gushushanya, cyangwa micro-crack mu gipangu cya PTFE ikanatera fibre yikirahure. PTFE ubwayo irashobora kugaragara neza, ariko umwenda utakaza imbaraga za mashini kandi urashobora guturika byoroshye. Nuburyo busanzwe bwo kunanirwa mugihe igifuniko cyangiritse.

Imiti yibasira mu buryo butaziguye PTFE

Ibi bintu bifata na PTFE ubwayo, ariko mubihe bikabije.

1. Ibyuma bya alkali byashongeshejwe - birasanzwe

Sodium ya sodium (Na), potasiyumu (K), na lithium (Li) ikuramo atome ya fluor ikomoka kuri PTFE, itera karubone, ibara ryirabura, hamwe nifu yubutaka bwibintu. Sodium-naphthalene igisubizo gikoreshwa mugukora PTFE ikora kuri iri hame.

• Ingaruka: Gusenya burundu imiterere ya PTFE.

• Ibisabwa: Ikintu cyose gihura nicyuma cya alkali gishongeshejwe (hejuru yibyo bishonga, urugero, Na kuri 98 ° C).

• Icyifuzo: Irinde burundu. Koresha firime nziza ya PTFE gusa nibiba ngombwa rwose, ndetse no mubwitonzi.

2. Ibikoresho bikomeye bya fluorine mubushyuhe bwinshi

Ibi bintu birashobora kubora PTFE munsi yubushyuhe bwinshi:

• Gazi ya Fluorine (F₂): Itera kwangirika gahoro gahoro n'ubushyuhe bwinshi.

• Floride ya interhalogen: Imiti ikabije cyane nka chlorine trifluoride (ClF₃) na promafluoride ya bromine (BrF₅) irashobora gutera reaction zikomeye cyangwa no gutwikwa kwa PTFE mubushyuhe bwinshi.

• Fluide ikomeye ya okiside: Urugero, xenon difluoride (XeF₂).

Icyifuzo: Komeza umwenda wa PTFE kure yiyi miti, cyane cyane ku bushyuhe bwo hejuru.

3. Gushonga alkalis ikomeye mubushyuhe bwinshi

Hydroxide ya sodium ya elegitoronike (NaOH) na hydroxide ya potasiyumu (KOH) bigenda byangirika buhoro buhoro hejuru ya PTFE hejuru ya 300 ° C, bigatuma habaho gutakaza hydrophobique hamwe nuburabyo bwo hejuru. Munsi ya 300 ° C, PTFE irwanya alkalis neza. Ku bushyuhe bwicyumba, nta ngaruka.

4. Ifu yicyuma ikora mubushyuhe bwinshi

Ifu ya Magnesium (Mg), ifu ya aluminiyumu (Al), nibindi bikoresho bisa nibitwara nabi na PTFE mubushyuhe bwinshi, bitanga fluoride yicyuma na karubone. Ngiyo ishingiro ryibintu bimwe na bimwe bya pyrotechnic no gutwika birimo PTFE.

Imiti yibasira Fiberglass Substrate ikoresheje inenge

Iyi miti ntabwo ikora hamwe na PTFE, ariko niba igifuniko cya PTFE gifite pinhole, gushushanya, cyangwa impande zose, bizinjira kandi bisenye fibre.

1. Hydrofluoric aside (HF) - iteje akaga cyane

Acide Hydrofluoric yangiza cyane fiberglass. Ifata vuba na dioxyde ya silicon (igice cyingenzi cyikirahure) kugirango ikore gaze ya silicon tetrafluoride, ishonga fibre yikirahure.

• PTFE ubwayo irwanya HF neza - PTFE ikoreshwa mubikoresho byo gukoresha HF.

• Nyamara, umwenda usize PTFE ntabwo ari umutekano kuri HF keretse iyo igifuniko kidafite pinhole rwose (biragoye cyane kubyemeza). Inenge iyo ari yo yose izemerera HF guhindagurika muri fiberglass, bigatera kunanirwa imyenda.

• Icyifuzo: Kuri serivisi ya HF, koresha firime nziza ya PTFE (nta fibre yububiko bwa fiberglass) cyangwa umurongo wuzuye wa PTFE wuzuye hamwe na zeru zeru zeru.

2. Alkalis yibanze cyane kubushyuhe bwinshi

Sodium hydroxide yibanze cyane (NaOH) igisubizo cyubushyuhe bwinshi irashobora kwangiza fiberglass ikoresheje ubusembwa. Icyumba-ubushyuhe, amazi ya alkalis afite umutekano.

3. Acide yibanze ya fosifori mubushyuhe bwinshi

Kumara igihe kinini hamwe na acide ya fosifori ishyushye bizatera kwangirika kwa fiberglass. Na none, PTFE ubwayo irayirwanya, ariko inenge zo gutwikira nizo ntege nke.

Ibyibutsa byingenzi kuri serivisi yimiti

1. Kunanirwa kwinshi biterwa no kwambara imashini cyangwa gusaza k'ubushyuhe, ntabwo ari imiti

Mubikorwa bisanzwe byinganda (ibihingwa bivura imiti, gutunganya ibiryo, nibindi), imyenda ya PTFE irananirana kubera gukuramo, gutanyagura, cyangwa kwangirika kwubushyuhe mbere yuko ruswa yimiti iba ikibazo. Imiti idahwitse ya PTFE nukuri kandi yizewe kumiti hafi ya yose igera kuri 260 ° C.

2. Niba ugomba gukoresha imiti ikaze, koresha firime nziza ya PTFE

Kubisabwa birimo ibyuma bya alkali byashongeshejwe, HF ishyushye cyane, cyangwa ibintu bikomeye bya fluor, PTFE ikozweho fiberglass ntabwo byemewe . Ahubwo, koresha:

• Filime nziza ya PTFE (skive cyangwa cast) idafite imbaraga za fiberglass

• Ibikoresho bya PTFE byuma

• PFA cyangwa FEP (izindi fluoropolymers zifite imbaraga zisa ariko imiterere ya mashini zitandukanye)

3. Buri gihe ugerageze mbere yo gukoresha byuzuye

Niba porogaramu yawe irimo imiti itashyizwe ku rutonde rwa 'umutekano ' mu mbonerahamwe isanzwe ihuza, kora ikizamini cyo guhuza ibintu mubikorwa nyabyo (ubushyuhe, kwibanda, igihe). Aokai PTFE irashobora gutanga ibizamini byo kwemeza.

Incamake - Guhuza imiti byihuse

Aokai PTFE itanga imiti ihuza imiti kandi irashobora gusaba ibicuruzwa byiza - umwenda usizwe na PTFE kubisabwa byinshi, cyangwa firime ya PTFE itunganijwe neza. Twandikire hamwe na chimique yawe yihariye, ubushyuhe, nigihe cyo kwerekana.

Ibiri hejuru byavuzwe na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba ushaka kumenya byinshi kubyerekeranye nibisobanuro birambuye, ibintu bisabwa hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, imikandara ya mashini ya PTFE, imikandara yimashini idahwitse, umwenda umwe wa PTFE, imikandara ya convoyeur irwanya ubushyuhe bwinshi hamwe nigitambara cyo hejuru cya fiberglass, nyamuneka twandikire:

• Bwana Guo: +86 18944819998

• Bwana Liu: +86 13705266308

Buri gihe dushyigikira filozofiya yumwuga nubunyangamugayo, kandi twiyemeje kuguha ibisubizo bimwe kandi serivisi zitaweho.
