Aokai PTFE ya inganta matakan shafi a cikin dubban ayyukan samarwa. Wannan jagorar yana bayanin yadda ƙimar haɓakawa ke shafar matakin daidaitawa, samuwar filaye, da lahani - da yadda ake sarrafa shi don tef ɗin PTFE mai inganci.

Yadda Ƙimar Ƙarfafawa ke Shafar Matsayi - Kashe Kasuwancin Danko

Haɓakawa shine ikon fim ɗin ɗanɗano mai ɗanɗano don kawar da ɗigon sutura, ratsi mai jujjuyawa, da nau'in kwasfa na orange-bawo, samar da ƙasa mai santsi. Ƙarfin tuƙi shine tashin hankali na sama; juriya shine danko.

1. Yayi sauri - fata fata yana daina daidaitawa

Lokacin da sauran ƙarfi ya ƙafe da sauri, ƙarfin ƙarfi a saman yana faɗuwa da sauri. Silicone PSA (maganin polysiloxane-nauyin nauyi mai girma) yana da matuƙar hankali. Dankin saman Layer yana tashi sosai - har ma yana samar da babban danko 'fata' kusan nan take.

Wannan fata tana kulle mannen da ba a warkewa ba a wuri. Manne ba zai iya ƙara kwarara zuwa matakin fitar da ɗigo ko alamar ruwa ba. Abubuwan da ba su dace ba da aka haifar yayin sutura ana gyara su har abada.

2. Yayi jinkirin - sagging da dewetting

Idan kaushi yana jujjuyawa a hankali a hankali, mannen Layer ɗin ya kasance mai ƙarancin danko na dogon lokaci. Duk da yake wannan yana ba da lokaci don daidaitawa, nauyi yana haifar da:

• Sagging (manne yana gudana ƙasa akan saman tsaye)

• Ƙaƙƙarfan gefuna ( tafkunan manne a gefuna na yankin da aka lulluɓe)

• Dewetting - a kan ƙananan-makamashi PTFE substrates (mahimmancin tashin hankali kawai 18-20 mN / m), tsawaita wetting na iya haifar da mannewa don raguwa kuma ya janye daga substrate, lalata shimfidar wuri.

Yadda Ƙimar Ƙarfafawa ke haifar da Pinholes

Finholes ƙananan ramuka ne ta cikin manne. Suna samuwa ne lokacin da kaushi ko kumfa na iska suka kama tarko kuma su fashe ta wurin daɗaɗɗen wuri kafin manne ya sake fitowa.

1. Mechanism 1 - tafasasshen ƙarfi da aka makale a ƙarƙashin fata

Lokacin da tef ɗin mai rufi ya shiga cikin tanda mai bushewa, haɓakar zafin jiki mai kaifi haɗe tare da saurin ƙarfi mai ƙarfi yana warkar da fuskar fim da farko. Maganin da aka makale a cikin Layer yana yin tururi da ƙarfi, yana haifar da kumfa. Da zarar matsatsin kumfa na ciki ya karya fata mai taurin kai, fim ɗin da ya fashe ba zai iya sake juyewa ya warke ba - yana barin ramukan dindindin ko ramuka masu kama da wuta.

2. Mechanism 2 - kumfa ba zai iya tserewa ba

Ana shigar da ƙananan kumfa a koyaushe yayin sutura da ciyarwar mannewa. Suna buƙatar isasshen lokaci don yin iyo sama, tsagewa, da warkarwa a ƙarancin ɗanko. Idan fatun saman ya yi sauri saboda bushewa da sauri, kumfa ba za su iya tserewa ba kuma ana gyara su azaman filaye.

3. Mechanism 3 - rashin lafiya wetting na ƙananan ramuka

Saurin saurin canzawa na farko yana haifar da danko sosai, yana hana mafita a hankali don cike ƙananan ramuka da fitar da iska mai tsaka-tsaki. Wannan yana haifar da lahani mai yawa-kamar fatalwa bayan bushewa.

Yadda Ƙimar Ƙarfafawa ke haifar da Craters (Dimples)

Craters ƙanana ne, zagaye-zagaye na baƙin ciki a saman manne, bambanta da ramuka. Rashin daidaituwar tashin hankali na gida ne ke haifar da su.

1. Mechanism 1 - magudanar ruwa

Rapid ƙarfi volatilization sha m vaporization zafi, sharply sanyaya rigar fim da substrate surface. Idan yanayin zafi ya faɗi ƙasa da wurin raɓa na yanayi, tururin ruwa a cikin iska yana takushewa zuwa ƙananan ɗigon ruwa akan rigar fim ɗin.

• Tashin ruwa na saman: ~ 72 mN/m

• Tashin hankali na mannen silicone: 20-25 mN/m

Wannan babban bambance-bambancen yana haifar da yanayin tashin hankali na gida wanda ke motsa abin da ke kewaye da su don nisanta shi daga ɗigon ruwa, yana barin ramuka bayan bushewa.

2. Mechanism 2 - gurɓataccen ramuka

Ƙunƙarar ƙaƙƙarfan tashin hankali (silicone micro-droplets, man shafawa) babu makawa sun wanzu a cikin manne ko yanayin aiki. Wadannan ƙazanta suna samar da ƙananan wuraren tashin hankali a kan fim ɗin rigar. A ƙarƙashin tasirin Marangoni, manne yana gudana waje daga waɗannan cibiyoyin, yana haifar da damuwa.

• Matsakaicin juzu'i yana ba da damar ɓacin rai don warkar da kai ta hanyar mannewa baya.

• Juyawa da sauri fiye da kima yana hana ruwa yin ruwa kafin waraka - ramuka suna kulle dindindin.

3. Mechanism 3 - ramukan dewetting daga rashin isasshen jika

Abubuwan PTFE suna da matsanancin tashin hankali na sama na 18-20mN/m kawai - daidai a bakin kofa na yuwuwar jika. Mannen silicone yana buƙatar isasshiyar taga mai ƙarancin danko don yadawa da jika saman da zafin jiki. Idan sauran ƙarfi ya yi saurin canzawa da sauri, mannen ya rasa ruwa kafin ya gama jika. A lokacin bushewa, ƙarar ƙarar da tashin hankali na saman yana tilasta mannewa zuwa kwangila, yana barin ƙananan ramuka a wuraren da ba su da kyau - ana iya gani a matsayin wuri mai alamar pockmarked.
