Imisebenzi yeeThickeners kwi-PTFE Emulsion – 4 Iindima eziphambili

Kwimveliso ye Ilaphu le-PTFE lobushushu obuphezulu , inyathelo lokungena lisebenzisa i-emulsion ye-PTFE (i-aqueous dispersion). Kodwa i-emulsion ye-PTFE ekrwada iyodwa kunzima ukuyiqhuba kakuhle. I-Thickeners yongezwa ukuguqula ukuziphatha kwayo kwe-rheological kunye nokuzinza.

Ngoba? I-PTFE resin inoxinano oluphezulu kwaye ithande ukuzinza. Ngaphandle kwee-thickeners, i-emulsion yayiza kwahlula, ingene ngokunzulu kwilaphu, okanye ivelise iingubo ezingalinganiyo.

I-Aokai PTFE ilwenze ukhetho olutyebileyo kuwo wonke amayeza ofakelo. Eli nqaku lichaza imisebenzi emine engundoqo ye-thickeners kwi-emulsion ye-PTFE.

Ukumiswa kozinziso kunye nokuchasana nokuZinzisa

Intlaka ye-PTFE inoxinano oluphezulu (malunga ne-2.2 g/cm³) kwaye ithande ukuzinza kwaye iqina kakhulu emanzini. Ngaphandle kokuzinzisa, i-emulsion ihlula kwi-sediment-rich layer kunye ne-liquid layer ecacileyo-eyenza ukuba ingasetyenziselwa ukugubungela okuhambelanayo.

Indlela ama-thickeners asebenza ngayo: I-Thickeners iphakamisa kakhulu i-viscosity yesigaba samanzi, senza isakhiwo sothungelwano esixhasa amasuntswana e-resin. Oku:

• Yandisa ubomi beshelufu ye-emulsion - ihlala isebenziseka iinyanga kuneentsuku

• Ikhusela ukuhlukana kwesigaba ngexesha lokuthutha kunye nokugcinwa

• Iphelisa i-caking - intlenga eqinile emazantsi ezikhongozeli

Inqaku le-Aokai PTFE: Kwi-emulsions egcinwe ngaphezulu kweentsuku ezingama-30, sicebisa ukuba i-homogenization iphinde isetyenziswe phambi kokusetyenziswa, nokuba ne-thickeners, njengoko ugcino olusisigxina lwexesha elide lusenokubangela ukucotha kokuzinzisa.

Ukuziphatha kokucheba ukuCwangcisa ngokulula

I-Thickeners inika i-emulsion ngokuziphatha kwe -shear-thinning (pseudoplastic): i-viscosity ephezulu ekuphumleni, i-viscosity ephantsi phantsi kokuphazamiseka..

Impembelelo esebenzayo: Ngexesha lokugquma idiphu, i-emulsion iqukuqela ngokukhululekileyo kwilaphu le-fiberglass phantsi kwe-chear, emva koko ijiye ngokukhawuleza emva kokugquma ukugcina ubukhulu befilimu obumanzi obufanayo ngaphandle kokuthontsiza.

Ukulawula ubunzulu bokungena kunye nobunzima bokugquma

Xa ufaka i-substrates ene-porous efana nelaphu le-fiberglass, ukulungelelanisa uhlobo kunye nedosi ye-thickeners ivumela ulawulo oluchanekileyo kubunzulu bokungena kwe-emulsion..

Indlela izinto ezijiyisa ngayo oku: I-viscosity ephezulu icothisa ukungena, ishiya intlaka eninzi phezu komhlaba. I-viscosity esezantsi ivumela ukungena okunzulu kwi-fiberglass bundle. Oku kugqiba ukulayishwa kwe-resin yokugqibela kunye nokuziva kwesandla kweemveliso ezigqityiweyo.

Ukuphucula ukufana komboniso bhanyabhanya kunye noQinisekisa ukuba akukho Sintering yaMahla

1. Ukufana kwefilimu ngexesha lokumisa

I-viscosity eyaneleyo evela kwii-thickeners:

• Icinezela ukuqhekeka okubangelwa ukufuduka ngokukhawuleza kokufuma ngexesha lokumisa

• Inqanda ukutyeba okungalinganiyo kokutyabeka (kwimiphetho etyebileyo, embindini obhityileyo)

• Iququzelela ukuqulunqwa kweefilimu eziziintloko ezizicaba, eziqhubekayo

• Yehlisa 'i-coffee ring effect' apho i-emulsion ifudukela emaphethelweni

2. Imfuno ebalulekileyo - i-residue-free sintering

I-emulsion ye-PTFE ifuna i-sintering malunga ne- 380 °C ukudibanisa amasuntswana e-PTFE kwifilimu eqhubekayo. Oku kunika imfuno ekhethekileyo yee-thickeners:

Izitshizi ezikhethiweyo kufuneka zitshise ngokupheleleyo ngaphandle kothuthu olushiyekileyo kobu bushushu.

I-Aokai PTFE isebenzisa i-cellulose-based thickeners (umzekelo, i-methyl cellulose) evutha ngokupheleleyo kwi-380 ° C, ingashiyi uthuthu. Sicebisa ukuba uthintele izinto ezityebileyo ezineetyuwa ezingaphiliyo okanye iioksidi zesinyithi ezishiya intsalela.

IsiShwankathelo – Iikhrayitheriya zoKhetho lwe-Thickener ye-PTFE Emulsion

I-Aokai PTFE ikhetha i-thickeners elungelelanisa yonke imisebenzi emine ngelixa iqinisekisa ukutsha okupheleleyo ngexesha lokutshisa. Ukulungiselela ukumiliselwa kwesiko, sinokuhlengahlengisa uhlobo lwe-thickener kunye nethamo ukuze lihambelane nobunzima bakho bokugquma kunye neemfuno zokungena kwelaphu.

Lo mfutshane wobugcisa unikezelwa ngu IJiangsu Aokai yeTekhnoloji eNtsha yeTekhnoloji Co., Ltd.

Ukuba ufuna iinkcukacha ezicacileyo, iimeko zesicelo kunye nezisombululo ezilungiselelwe uluhlu olupheleleyo lweemveliso ezibandakanya amalaphu e-PTFE aphezulu obushushu, iiteyiphu ezincamathelayo ze-PTFE, amabhanti e-mesh ye-PTFE, amabhanti omatshini wokudibanisa angenamthungo, ilaphu elityatyekwe kwicala elinye le-PTFE, amabhanti okuhambisa anganyangekiyo ubushushu kunye nobushushu obuphezulu obungaphantsi kwe-fiberglass nceda uqhagamshelane nathi ngelaphu.
