Indlela yokususa i-Residual Addives kunye ne-Low-Molecular Substances kwi-Coating ngexesha lokuveliswa kwe-PTFE High-Temperature Cloth

IZixhobo eziNtsha zeJiangsu Aokai – PTFE uMvelisi weLaphu lobushushu obuphezulu, ubonisa indlela. Ngexesha lokuveliswa kwengubo ephezulu ye-PTFE yobushushu obuphezulu, izongezo ezishiyekileyo kunye nezinto eziphantsi kweemolekyuli kwi-coating zizinto eziphambili ezichaphazela ukumelana nobushushu bokugqibela, ukukhutshwa kwepropati kunye nokhuseleko lokutya kwemveliso. Ukuqinisekisa ukusebenza kwelaphu le-PTFE lobushushu obuphezulu liyahlangabezana nemigangatho, inkqubo engqongqo yamanqanaba amaninzi ibalulekile ukususa obu kungcola.

Inqanaba lokuqala: UNyango oluPhambili lwe-Thermal lwe-PTFE yoKutyabeka ngelaphu lobushushu obuphezulu

Le yeyona nkqubo ibaluleke kakhulu kwimveliso yelaphu yobushushu obuphezulu be-PTFE, efikelela ukwahlulwa ngokwasemzimbeni kokungcola okugqumayo ngolawulo oluchanekileyo lobushushu.

Emva kokufakwa kwe-emulsion ye-PTFE ye-PTFE yobushushu obuphezulu belaphu substrate, imveliso kuqala ingena kwi-oven yokomisa ubushushu obuphantsi. Kwifilimu emanzi phezu komhlaba, ukushisa ngokuqhelekileyo kulawulwa kwi- 240-285 ° C. Eli nyathelo alijolisanga ukwenza ifilimu yokugquma, kodwa ukwenza i-volatilize ukufuma, i-solvents kunye ne-surfactants kwizithuba zokugquma ngomoya oshushu. Ukutsiba eli nqanaba kunye nokuqhuba ngokuthe ngqo i-high-temperature sintering kuya kubangela imingxunya okanye amaqamza phezu komhlaba, ukonakalisa kakhulu ukuxinana kwelaphu le-PTFE lobushushu obuphezulu.

Emva koko, ilaphu le-PTFE elinobushushu obuphezulu lingena kwindawo yobushushu obuphezulu be- 360-380 ° C. Kweli qondo lobushushu, amasuntswana e-PTFE kumphezulu aqala ukunyibilika kwaye ahambe, enze ifilimu eqhubekayo ekhuselayo. Okwangoku, eli qondo lobushushu lingaphezulu kwendawo yokunyibilika ye-PTFE inika amandla ekinetic awaneleyo kwii-oligomers ezishiyekileyo kunye nee-monomers ezingaphendulwanga ngaphakathi kwengubo ukuze zibe ngumphunga kwaye zibaleke kwi-substrate. Ulawulo oluchanekileyo lobushushu be-sintering lubalulekile kucoceko lwelaphu lobushushu obuphezulu be-PTFE:

· Amaqondo obushushu angaphantsi kwe-360°C akhokelela ekuguquguqukeni okungaphelelanga kobumdaka bangaphakathi;

· Amaqondo obushushu angaphezu kwe-390 ° C abangela ukuphuka kunye nokubola kwe-PTFE yamaketanga eemolekyuli, ukungcolisa i-coating endaweni yoko.

Inqanaba leSekondari: Ulawulo lweNkqubo eLungileyo kwi-PTFE iMveliso yeLaphu lobushushu obuphezulu

Ukongeza kunyango oluphambili lwe-thermal, ulawulo oluneenkcukacha ngexesha lemveliso lukwanceda ukuphucula ibakala lokucoceka kwelaphu le-PTFE lobushushu obuphezulu.

· Unyango lwangaphambili lwe-Substrate : Phambi kokugquma, ilaphu le-fiberglass elisetyenziselwa i-PTFE ilaphu lobushushu obuphezulu lenziwa ngokucokisekileyo ukuthotywa kunye nonyango lwe-degumming. Iintsalela ze-Organic kwi-cloth yesiseko ziya ku-carbonize ngexesha lokufudumeza okulandelayo kwaye zihlale kwi-interlayer, zenze iziphene eziqhubekayo ezingenako ukupheliswa.

· Ukucoca okuNcedisayo : Kwi-PTFE i-cloth ephezulu yokushisa ifuna ukucoceka okuphezulu, ukucocwa kwe-intanethi kunye ne-solvents ethile okanye unyango lwe-ultrasonic lunokusetyenziswa kwiimveliso ezigqityiweyo, ukuphucula ukukhutshwa kothuli lomhlaba kunye nokucocwa kwe-oyile.

Inqanaba lesithathu: iQhinga loLawulo loMthombo kwi-PTFE iMveliso yeLaphu lobushushu obuphezulu

Eyona ndlela yokucoca ifanelekileyo kukuthintela ukungcola phambi kokuba bangene kwinkqubo yemveliso, efuna ababoneleli ngelaphu lobushushu obuphezulu be-PTFE ukuseka imigangatho engqongqo yolawulo lomthombo.

· UKhetho lweMathiriyeli ekrwada ekwiMgangatho oPhezulu : Kuphela kuphela i-PTFE dispersion resins ezicocekileyo ezinobunyulu obungekho ngaphantsi kwe-99.9% kufuneka zisetyenziswe njengezinto zokwaleka ekrwada. Iireyini zomgangatho ophantsi ziqulethe izinto eziphantsi-molekyuli ezigqithisileyo, zenza kube nzima ukuvelisa ilaphu lobushushu obuphezulu be-PTFE kungakhathaliseki ukuba i-sintering ilungiswa njani kamva.

· Ulawulo lwe-Agent eNcedisayo : Xa izithambiso okanye ii-agent zokulinganisa ziyimfuneko ekwenziweni kwe-coating, iintlobo zokubilisa okuphantsi, eziguquguqukayo kakhulu ziya kunyulwa, kwaye idosi yabo ilawulwe ngokungqongqo ukuqinisekisa ukupheliswa ngokupheleleyo kwimveliso egqityiweyo.

· Imeko ecocekileyo yeMveliso : Iworkshop yemveliso iya kugcina uxinzelelo olulungileyo kunye nococeko. Izixhobo zangaphakathi zezixhobo zifakwe kwi-PTFE okanye zenziwe ngensimbi engenasici ukukhusela uthuli kunye ne-debris ukusuka kwimo engqongileyo okanye i-abrasion yezixhobo zokuwela kwifilimu emanzi kunye nokwenza amabala okungcola okunemibala kwi-coating.

Undoqo wokususa izinto ezishiyekileyo kwi-PTFE yokwambathwa kwelaphu lobushushu obuphezulu ilele kulawulo oluchanekileyo lobushushu be-sintering kunye nejiko lokufudumeza. Kuphela ngokudibanisa unyango lwe-thermal kunye nolawulo lococeko olugcweleyo lunokuthi ilaphu le-PTFE eligqityiweyo lobushushu obuphezulu linikeze iipropati ezigqwesileyo ezingenakukhuni, ukumelana nobushushu kunye ne-high-insulation properties.

Olu lwazi lungasentla lunikezelwe nguJiangsu Aokai New Materials Technology Co., Ltd.

Iiparameters ezineenkcukacha, iimeko zesicelo kunye nezisombululo ezilungelelanisiweyo zoluhlu olupheleleyo lweemveliso ezibandakanya i-PTFE yelaphu lobushushu obuphezulu, i-PTFE iteyiphu yobushushu obuphezulu, i-PTFE ye-mesh belt, ibhanti elingenamthungo lomatshini wokubopha, ilaphu le-PTFE elisecaleni elinye, ubushushu obuphezulu obuphezulu obunganyangekiyo, ibhanti lobushushu elinobushushu obuphezulu, nceda uzive ukhululekile kwiglasi yokuhambisa.
