PTFE Emulsion Coated Fiberglass Fabric - Sintering Ho Tšoara Litlhoko tsa Nako

Sintering ke mohato oa bohlokoa moo likaroloana tsa PTFE li qhibilihang, li phallang, 'me li kopanya filimi e tsoelang pele, e teteaneng e tlamahanang le fiberglass substrate. Haeba nako ea ho tšoara e le khutšoanyane haholo, ho roala ho lula ho e-na le porous le ho fokola. Haeba nako e telele haholo, PTFE e senyeha, e ntša likhase tse chefo le ho fetoha brittle.

Parameter ea bohlokoa ke nako ea ho tšoara - nako ka mor'a hore bongata ba ho roala bo fihle mocheso oa sintering (ka tloaelo 370-400 ° C). Ena hase feela nako eo sebōpi se leng mochesong oa sona; ke nako ea lesela ka boeona le ka holim'a ntlha e qhibilihang.

Aokai PTFE e ntlafalitse li-parameter tsa sintering ho pholletsa le mela e mengata ea lihlahisoa. Tataiso ena e akaretsa litlhoko tsa nako ea ho ts'oara bakeng sa mefuta e fapaneng ea sebōpi, lintlha tsa mantlha tse susumetsang, le bofokoli ba nako e sa lokelang.

Melao-motheo ea Motheo - Se Bolelang 'Ho Tšoara Nako'.

1. Sepheo sa mantlha

Ho lumella likaroloana tsa PTFE hore li qhibilihe ka ho feletseng, li phalle, 'me li fuse ka holim'a ntlha ea tsona ea ho qhibiliha (hoo e ka bang 327 ° C ), ho etsa filimi e tsoelang pele le e teteaneng e finyellang mokhoa o thata oa ho kopanya le fiberglass substrate.

2. Phapang ea bohlokoa

Ho boloka nako ho bolela nako e tsitsitseng ka mor'a hore bongata ba ho roala bo fihle mocheso oa sintering (hangata 370-400 ° C), ho e-na le nako feela eo mocheso oa sebōpi o lulang o le teng.

Ho bohlokoa ho netefatsa hore botenya bo felletseng ba lesela la fiberglass (ho kenyeletsoa le resin e ts'oeroeng lipakeng tsa likhoele tsa fiber e kahare) bo fihla mochesong o qhibilihang mme bo tšoare nako e lekaneng. Mocheso oa holim'a metsi feela ha oa lekana - likarolo tse ka hare le tsona li tlameha ho qhibiliha.

Mekhahlelo ea Litšupiso bakeng sa Mekhoa e Tloaelehileng

1. Sebōpi se sa khaotseng sa sintering

Tlhophiso ea mocheso oa sebōpi: Ho futhumatsa libaka tse ngata ka sebaka sa mocheso o phahameng se behiloeng ho 380-400 ° C (ho fihla ho 410 ° C bakeng sa mekhoa e itseng e ikhethileng).

Nako ea bolulo e sebetsang hantle (nako ea ho ts'oara) sebakeng sa mocheso o phahameng:

Phetoho e sebetsang: Tune lebelo la mohala ho latela bolelele ba sebōpi - fokotsa lebelo la maeto a masela ho eketsa nako ea ho lula ha mocheso o phahameng.

2. Sebōpi sa sebōpi sa batch (mofuta oa lebokose).

Tšoara mocheso o sa khaotseng ho 380-390 ° C ka mor'a ho futhumatsa:

Khopotso: Libōpi tsa mabokose ha li na mocheso o lekaneng. Moea o potolohang ka lebelo le phahameng oa hlokahala, 'me nako ea ho ts'oara e tla atolosoa ka nepo ho qoba ho kenella ka tlase ho lilae tse kahare.

Lintlha tse ka sehloohong tse khethollang nako ea ho tšoara

Lintlha tse hlano tsa bohlokoa lia sebelisana ho fumana nako e nepahetseng ea ho ts'oara sehlahisoa se itseng.

1. Fiberglass lesela botenya le boima ba 'mele

Masela a maholo, a boima ho feta a na le tsamaiso e fokolang ea mocheso 'me a hloka nako e telele ea ho tšoara mocheso hore mocheso o kenelle bohareng.

2. Coating passes le PTFE loading

Likarolo tse ngata tsa ho roala li theha lifilimi tse teteaneng tsa resin tse hlokang ho futhumatsoa ho atolositsoeng ho qhibilihisa koae e tlase ka botlalo. Liaparo tse le 'ngoe tse tšesaane li lumella nako e khutšoanyane ea ho tšoara.

3. Kereiti ea emulsion ea PTFE

• Li-emulsions tse hloekileng tsa PTFE - li hloka mocheso o phahameng oa sintering le nako e lekaneng ea ho lula

• Metsoako e fetotsoeng (e kopantsoeng le PFA kapa FEP) - e bonts'a phallo e phahameng ea ho qhibiliha le ho lumella ho fokotsa nako ea ho ts'oara

4. Mocheso oa sintering

• Lithempereichara tse phahameng tse behiloeng (mohlala, 400°C) - khutsufatsa nako e hlokahalang ea ho tšoara

• Lithempereichara tse haufi le moeli o tlase (370°C) - li hloka ho futhumatsa nako e telele

• Fesetere ea 380-390 ° C e leka-lekanya katleho ea tlhahiso le kotsi ea ho senyeha ha PTFE

5. Moralo oa sebōpi le lebelo la moea o chesang

• Lisebelisoa tse nang le moea o chesang ka lebelo le phahameng kapa ho kenella ha infrared - phetisetso e sebetsang ea mocheso, nako e khuts'oane ea ho ts'oara

• Libōpi tse itšetlehileng feela ka mocheso o khanyang - ho hlokahala nako e telele ea ho lula

Mefokolo e Bakiloeng ke ho Tšoara Nako e sa Tšoaneng

1. Nako e sa lekaneng ea ho tšoara (under-sintering)

Ho lemoha: Tlhahlobo ea pono (e tšoeu e opaque, e thollo), teko ea ho hula tepi (ho phunya), tlhahlobo ea likarolo tse ling (likaroloana tse tšoeu tse sa qhibilihisitsoeng ka hare).

2. Ho tšoara nako e telele ho feta tekano (over-sintering)

Ho lemoha: Tlhahlobo ea pono (e mosehla, matheba a tlabola), tlhahlobo ea brittleness (mapetso ha e kobehile), ho lemoha monko (monko oa acrid o bontša ho bola).

Maemo a Sebetsang a Tlhahlobo le Malebela a Ntlafatso ea Ts'ebetso

1. Theha likhahla tsa nako ea mocheso

Sebelisa tracker ea mocheso oa sebōpi ho hatisa mocheso oa lesela la nako ea sebele le ho netefatsa nako e sebetsang ea ho qhibiliha ka holimo ho 370°C. Ena ke tsela e ka tšeptjoang ka ho fetisisa ea ho netefatsa nako ea sebele ea ho tšoara.

2. Tlhahlobo ea kholo ea pono

Liaparo tsa PTFE tse kentsoeng ka botlalo li teng:

• Uniform semi-transparent ho ponahalo e hlakileng ka botlalo (e fapana ka botenya)

• Ha ho na chelky unmelted particles

• E bonolo ho ama (eseng e thata kapa e brittle)

3. Teko ea ho khomarela

Ha ho na masala a peeling kapa phofo ka mor'a teko ea ho hula ka tepi kapa ho khumama khafetsa (mena / bula makhetlo a 5-10).

4. Tlhahlobo e senyang ea likarolo tse fapaneng

Likarolo tse fapaneng tsa lesela le sehiloeng li bontša:

• Ha ho na likaroloana tse tšoeu tse sa qhibilihang ka hare

• Likhoele tsa fiberglass tse kolobisitsoeng ka botlalo ke resin e qhibilihisitsoeng ea PTFE

5. Mehato ea tšireletso le ho pholile ho qobelloa

• Boloka moea o matla oa ho ntša moea ho thibela ho bokellana ha lintho tse chefo (perfluoroisobutylene, HF) ho tloha ho bola ha PTFE.

• Koahela ka tieo mocheso o phahameng le nako ea ho ts'oara

• Hang-hang fepa lesela sebakeng se qobelloang sa ho pholisa ka mor'a hore karolo ea mocheso o phahameng o fokotsehe ka tlase ho 300 ° C ka potlako - ho pholisa ka potlako ho thusa ho koala microstructure e kopantsoeng.
