Kutheni le nto i-Sintering ilelona nyathelo libaluleke kakhulu ukumisela iNdlela yokuGqibela ye-PTFE Coated Fiberglass Fabric?

E-Jiangsu Aokai Advanced Materials Technology Co., Ltd., inkqubo ye-sintering ye-PTFE coated fiberglass ilaphu ithathwa 'njengentliziyo kunye nomphefumlo' wemveliso. Itshintsha ngokusisiseko amasuntswana e-PTFE abambeneyo ngokwasemzimbeni abe ngumaleko wefilimu oqhubekayo kunye nokusebenza okugqwesileyo, ukugqiba ukuba i-PTFE ilaphu ingaba yinto edibeneyo yokusebenza ephezulu. Oku kuhlalutywa nzulu ukusuka kwimilinganiselo emine engezantsi.

1. Ukuguqulwa kweMicrostructural: Ukusuka 'Ukupakishwa kweNgxenye' ​​ukuya 'Ukwenziwa kweFilimu eqhubekayo'

Emva kokufakwa kunye nokomisa, i-PTFE ikhona kuphela njengamaqhekeza, amasuntswana amahle afakwe kumphezulu kunye nangaphakathi kwe-interstices ye-fiberglass substrate. Ngeli nqanaba, ilaphu eligqityiweyo alinawo amandla asebenzayo, kwaye i-coating isuka ngokulula ngokungqubuzana okuncinci.

Indima ye-Sintering :Kubushushu obuphezulu be-360-380 ° C, amasuntswana e-PTFE ancibilika, asasazeke, kwaye ahlangane ukuze enze ifilimu exineneyo, eqhubekayo, engeyiyo i-porous efaka ngokupheleleyo i-fiberglass. Ngaphandle kolu tshintsho, ilaphu alikwazi ukuphumeza utyikityo lwalo olungabambekiyo, lumelana neekhemikhali, kunye neempawu zombane.

2. Ukumisela amandla eBond kunye neePropati zoomatshini

I-Fiberglass kunye ne-PTFE zizixhobo ezingafaniyo ngokwendalo. Unxulumano olungekho mgangathweni oluphakathi kobuso lukhokelela ekugqunyweni kwe-delamination, ukugqabhuka, okanye ukuxobuka ngexesha lenkonzo.

I-Interfacial Fusion kunye neCrystallinity Control :Ngexesha le-sintering, i-PTFE etyhidiweyo ingena kwaye i-anchors kwi-micropores kunye nomgangatho orhabaxa we-fiberglass, idala i-mechanical interlocking. Okwangoku, ubushushu obuchanekileyo be-sintering kunye nezinga lokupholisa elilawulwayo lilawula i-crystallinity ye-PTFE. Uphando lubonisa ukuba ilaphu le-PTFE elingaphantsi kwe-sintered linobukhazikhazi obuphantsi kunye nokuncamathela okumbi kakhulu, kunye neengubo eziguga ngokukhawuleza phantsi kokugotywa okuphindaphindiweyo okanye ukukrazuka. Kuphela yinkqubo ye-sintering elawulwa ngokungqongqo eqinisekisa ukomelela kwe-peel, ukomelela, kunye nobomi obuguquguqukayo.

3. Ukudala ukuxinana kokugqibela kunye nesithintelo soKhuseleko

I-Fiberglass ngokwayo i-brittle, ayinxibi kakuhle, kwaye ichaphazeleka kwi-hydrolysis. Ukusebenza okugqwesileyo kwe-PTFE ilaphu eligqunyiweyo lixhomekeke ngokupheleleyo kumaleko akhuselayo e-PTFE.

Ukuphelisa iziphene kunye nokwenza umqobo :I-Sintering fuses kunye nokuphelisa i-pinholes encinci, amaqamza omoya, kunye nezinye iziphene ezivela kwiinkqubo zangaphambili, ukwenza i-integment 'isikrweqe sokukhusela.' Lo mqobo oxineneyo wenza ukuchasana kwexesha elide kwi-acids eqinile, i-alkali, kunye ne-solvents ye-organic, ngelixa uhambisa i-non-stick kunye nokusebenza kombane wokugquma. Ngamafutshane, umgangatho we-sintering uchaza ngokuthe ngqo umda wesicelo selaphu - nokuba yenzelwe iinjongo eziqhelekileyo zebhanti zokuhambisa okanye i-aerospace-grade insulation.

4. Uvakalelo olugqithisileyo lweeParamitha zeSintering kuMgangatho weMveliso

I-Sintering ineyona nkqubo imxinwa kwaye inzima kakhulu kwimveliso yelaphu ye-PTFE; ukutenxa kancinci kwiparameters kukhokelela kumahluko omkhulu ekusebenzeni.

Ulungelelwaniso oluchanekileyo loBubushushu kunye nexesha :Ubushushu obungonelanga okanye ubude bexesha bukhokelela 'kwi-under-sintering': I-PTFE iyasilela ukwenza ifilim-ifom epheleleyo, ishiya isambatho esixekileyo, esimhlophe, esiluthuntu kunye nokunganyangeki kakuhle kweekhemikhali. Ubushushu obugqithisileyo okanye ixesha lokuhlala libangela ukubola okushushu kwe-PTFE, ukukhupha imisi eyityhefu, ukunciphisa amandla e-substrate, kunye nokwenza ilaphu libe brittle kwaye libe tyheli, lilenze lingasebenziseki.

Impembelelo egqibeleleyo yeqondo lokupholisa :Isantya sokupholisa emva kokucolwa simisela ubume bekristale kunye nobukhazikhazi be-PTFE. Ukupholisa ngokukhawuleza kuvelisa i-crystallinity ephantsi, ilaphu elibhetyebhetye kakhulu elilungele usetyenziso oluguquguqukayo lokugoba. Ukupholisa okucothayo kubumba ubukristale obuphezulu, ubulukhuni obuphezulu, ilaphu elingagugiyo elilungele ukutywinwa okuzinzileyo.

Ukuqukumbela

Ngokulawulwa ngokuchanekileyo 'kwimbali ye-thermal,' inkqubo ye-sintering ifezekisa ukunyibilika kwe-PTFE, ukubunjwa kwefilimu, i-crystallization, kunye ne-interfacial bonding kunye ne-fiberglass, ukuguqula imveliso ebuthathaka egqityiweyo ibe yinto ephezulu yokusebenza. Imisela ngokusisiseko ukumelana nobushushu, ukuzinza kweekhemikhali, amandla oomatshini, ukugqunywa kombane, kunye neempawu ezingaphezulu zelaphu le-PTFE elakhiwe ngefiberglass. Ke ngoko, i-sintering ngokungathandabuzekiyo lelona nqanaba libaluleke kakhulu kuyo yonke inkqubo yemveliso, kwaye inqanaba letekhnoloji limele ngqo ukhuphiswano lobuchule olungundoqo lwabavelisi belaphu be-PTFE.

Olu lwazi lungentla lunikwe nguJiangsu Aokai Advanced Materials Technology Co., Ltd.
