Uzinqanda njani iiNgxaki eziBangwe kuKwandiswa kweThermal kwi-PTFE Ubushushu obuphezulu beFabric Applications

Ilaphu le-PTFE lobushushu obuphezulu alinayo i-coefficient esisigxina yokwandiswa kwe-thermal (CTE). Ngokungafaniyo nentsimbi okanye iplastiki eqinileyo, ukuziphatha kwayo okwandisiweyo kuchatshazelwa ngokudibeneyo ngelaphu lesiseko se-fiberglass, umxholo wokulayisha we-PTFE, ulwakhiwo olulukiweyo, kunye noluhlu lobushushu obusebenzayo.

Oku kuntsonkotha kukholisa ukukhokelela kwiingxaki ezingalindelekanga: amabhanti okuhambisa amabhanti, iigaskets ezikrazukileyo, iileya ezidityanisiweyo, okanye iileyina eziphothiweyo zokukhulula. Ukuqonda kunye noyilo lokwandiswa kwe-thermal kubalulekile ekusebenzeni okuthembekileyo kwexesha elide.

I-Aokai PTFE iye yahlalutya isimilo sokwandiswa kwe-thermal kuzo zonke izicelo ezininzi. Esi sikhokelo sichaza amaxabiso aqhelekileyo e-CTE kwaye sibonelela ngezisombululo ezithandathu ezisebenzayo ukuphepha ukungaphumeleli okunxulumene nokwandiswa.

Ii-Coefficients eziqhelekileyo zoKwandiswa kweThermal - Yazi amanani akho

1. Isalathiso se-PTFE ecocekileyo

I-PTFE esulungekileyo inomlinganiso ophezulu womgca wokwandiswa kwe-thermal: malunga ne- 10×10⁻⁵ – 20×10⁻⁵/°C (100–200 ppm/°C) kwiqondo lobushushu begumbi, ngokuguquguquka okungeyo-layini njengokutshintsha kobushushu.

Inqaku elibalulekileyo: I-PTFE idlula kwiinguqu zesigaba se-crystalline malunga ne- 19 ° C kunye ne-30 ° C , ekhokelela ekutshintsheni kwevolumu ngokukhawuleza kwe- 1% -2% . Olu phawu lufuna ingqalelo ekhethekileyo kwizicelo ezichanekileyo. Ifilimu ye-PTFE enemitha eyi-1 ubude ingakhula nge-1-2 cm ngokudlula nje kubushushu begumbi.

2. Ilaphu le-PTFE eliphezulu lobushushu (i-fiberglass substrate) - uluhlu oluqhelekileyo lwe-CTE

I-Fiberglass ngokwayo ine-ultra-low CTE ye-approx. 5×10⁻⁶/°C (5 ppm/°C) , esebenza njengesakhelo esomeleleyo sokunqanda ukwandiswa kwe-PTFE kunye nokunciphisa kakhulu ukwandiswa kwe-thermal kwinqwelo-moya yelaphu eligqityiweyo. Nangona kunjalo, ulwakhiwo olulukiweyo lusakhokelela ekwandiseni okuphezulu kunelaphu le-fiberglass ecacileyo.

Ukwandiswa ecaleni kobukhulu becala kubaluleke kakhulu ngenxa yomlinganiselo ophezulu we-PTFE resin. Ngeenjongo zobunjineli, kuphela iinguqu zedimensional zenqwelomoya ezibekwe phambili ngokubanzi.

UYilo lweziCwangciso zeZakhiwo zokwandiswa kweThermal

1. Imida yokwandisa yasimahla

Xa isetyenziswa njenge gaskets, i-thermal insulation mats, okanye umphezulu wokutyibilika, thintela ukulungiswa okupheleleyo macala omane. Gcina umphetho omnye okanye emibini ekhululekileyo ukuvumela ukolula nokucutheka kwe-thermal okungathintelwanga.

2. Imingxuma yokuxhoma emide

Ukuba kufuneka ubophelelo lwebholithi, yandisa imingxunya okanye wamkele imingxunya emide ebotyiweyo. Musa ukuziqinisa ngokupheleleyo iibholithi; yongeza iigaskets ukugcina isibonelelo esincinci sokutyibilika. Oku kuvumela ukuba izinto eziphathekayo zandise kwaye zikhontrakthi ngaphandle koxinzelelo loxinzelelo kumanqaku e-bolt.

3. Ukwaleka okucandekileyo

Ukufakela indawo enkulu, yahlula ilaphu kwiipaneli ezihlukeneyo kunye ne- 3-5 mm yokwandiswa kwamalungu phakathi kwamaqhekeza, ngokukodwa kwicala lobude. Oku kuthintela i-buckling ukusuka kulwandiso olongezelekayo kwiindawo ezide.

Kuthintele ukuHamba ngeBhayisikile okuKhawulezayo kwiThermal KwiSigaba soTshintsho oluBalulekileyo lobushushu

I-PTFE inengxaki yokuguquguquka okukhulu kwevolumu kufutshane nobushushu begumbi – ngakumbi kwi- 19°C kunye ne-30°C indawo zotshintsho. Ukuba isixhobo sihlala sitshintshana phakathi kogcino olubandayo kunye nobushushu be-ambient, musa ukucinezela ilaphu le-PTFE liqiniswe kakhulu.

• Xa ifakwe kwiqondo lokushisa eliphantsi kodwa lisebenza phantsi kobushushu obuphezulu, ilaphu liya kuba lide (umzekelo, ilaphu lemitha eli-1 lolula iimilimitha ezininzi xa lifudumala ukusuka kwi-25 ° C ukuya kuma-200 ° C).

• Ukuxhobisa iindibano zokuxinana ngembuyekezo ezenzekelayo (iinkqubo ezilayishwa entwasahlobo okanye ezichasene nobunzima) endaweni yokutshixa okuqinileyo.

Umgaqo obalulekileyo: Ungaze ucinezele ilaphu le-PTFE liqinile kwiqondo lobushushu begumbi kwaye emva koko ulifudumeze – ukwandiswa kuya kudala ama-ripples. Ungaze uyicinezele ngokuqinileyo kwiqondo lobushushu eliphezulu kwaye emva koko uyipholise - ukushwabana kuya kukrazula okanye kucinezele kakhulu loo nto.

Uyilo lwe-Anti-Buckling yokuGqibela kunye neZidibaniselwano

• Ukugqithela ecaleni kwendlela yolwandiso , kwaye uqinisekise ukuba ububanzi obuthe xhaxhe bungaphezulu kobude obuqikelelweyo.

• Kwimithungo ethungiweyo , shiya isibonelelo esikhululekileyo kwimisonto yokuthunga. Ukuba idityaniswe kunye ne-adhesive yobushushu obuphezulu, khetha iglue elastiki ukuthintela ukukrazuka okubangelwa kukungahambelani kokwandiswa kwee-coefficients.

• Ukupakishwa kwemigangatho emininzi , kunqanda ukudityaniswa komphezulu ogcweleyo. Yamkela ukudityaniswa kwendawo okanye ukulungiswa kwezahlulo ngemicu yeendaba ukuze kuvumeleke ukutyibilika kwe-interlayer-ukuphelisa amadyungudyungu kunye ne-delamination.

Ulawulo loxinzelelo lweemeko zokuSebenza

1. Izicelo zebhanti lokuhambisa

Faka i-counterweight okanye i-spring-loaded tensioners ezenzekelayo ukuze ufunxe ukuphumla kwelaphu kumaqondo aphezulu kunye nokushwabana kumaqondo aphantsi. Ungalokothi uqinise ibhanti phantsi kobushushu obuphezulu - oku kuya kubangela ukugqithiswa ngexesha lokunciphisa okubandayo. Uxinzelelo lwebhanti kufuneka lubekwe kwelona qondo liphantsi lilindelekileyo lobushushu bokusebenza.

2. Khupha ii-liners kunye namaphepha odwa

Lala ngaphandle koxinzelelo lwangaphambili. Khusela kancinci ngobunzima bokuzimela okanye imicu yokucofa emxinwa kwicala elinye ukukhusela i-creases esisigxina ebangelwa kukwandiswa kwe-thermal.

Nciphisa ukuGqwetheka ukusuka kwiiGradiyethi zoBubushushu obuMandundu

Ukwandiswa okungalinganiyo kwenzeka xa elinye icala lelaphu libonakaliswe kubushushu obuphezulu ngelixa elinye lihlala lipholile, libangela ukulwa.

Amanyathelo okulungisa:

• Ukubamba okungapheliyo ngezakhelo endaweni yoxinzelelo olupheleleyo oluqhubekayo

• Khetha ilaphu elingqingqwa, elinoxinaniso oluphezulu lwefiberglass ukunciphisa iphepha lokulwa

• Seta kwangaphambili i-arching ebuyela umva kwicala lobushushu obuphantsi ukuba kuyimfuneko (i-curve yangaphambili ilaphu ukuze libe mcaba kubushushu bokusebenza)

Ukuhlolwa kwamaxesha athile kunye noLondolozo

Emva kwexesha elide lokuhamba nge-thermal, i-PTFE iya kuba ne -deformation ehambayo ebandayo , ekhokelela kubude obusisigxina okanye ukudodobala kwendawo.

• Hlola rhoqo kwaye ulungise amanqanaba oxinzelelo - amabhanti anokufuna ukunyanzeliswa kwakhona emva kwemijikelo yokuqala ye-thermal.

• Lungisa i-bulges kunye ne-delamination ngokukhawuleza ukunqanda ukugxila kuxinzelelo kunye nokukrazula.

• Ukuziphatha kolwandiso lwamaxwebhu - ukuba ibhanti lihamba ngokuqhubekayo ngaphaya koluhlu lohlengahlengiso, linokufuna ukutshintshwa okanye i-substrate ehambelana ne-CTE eyahlukileyo.

Ingcebiso ye-Aokai PTFE: Kwizicelo ezinebhayisekile eshushu ngokugqithisileyo (umzekelo, abahambisi be-oveni bahamba ngebhayisekile ukusuka kwindawo ukuya kwi-250°C amaxesha amaninzi ngemini), sicebisa ilaphu elinomxholo ophezulu we-fiberglass (ephantsi kwe-CTE) kunye nokujongwa koxinzelelo oluzenzekelayo.

IsiShwankathelo – Uluhlu loYilo loKwandiswa kweThermal
