Ndi Maudindo Otani Amene Ma Surfactants Wamba mu PTFE Dispersions Amasewera Panthawi Yoyimba ndi Kuyimba?

Monga katswiri wopanga nsalu za PTFE zokutira magalasi a fiberglass, Jiangsu Aokai New Material amawonjezera zopangira zoyenera panthawi ya PTFE kubalalitsidwa kwazinthu zapadera. Ma Surfactants ali m'gulu la zigawo zofunika kwambiri za PTFE dispersions, ndi ntchito zomwe zikuyenda panthawi yonse yopanga.

Maudindo Panthawi ya Impregnation

· 

Emulsion Kukhazikika PTFE particles ndi mwachibadwa hydrophobic ndipo amakonda agglomerate m'madzi. Ma surfactants amatsekereza tinthu tating'onoting'ono kuti tipangitse steric chotchinga, zomwe zimawalola kukhalabe mokhazikika komanso mofanana kuyimitsidwa m'madzi kwa nthawi yayitali ndikuletsa kugwa.

· 

Surface Tension Adjustment Surfactants amachepetsa kwambiri kugwedezeka kwapamtunda kwa kubalalitsidwa mpaka pansi pa mphamvu ya gawo lapansi loyimbidwa (monga fiber fiber). Zimenezi zimathandiza kubalalitsidwa kufalikira mofulumira ndi kulowa kwambiri, kuonetsetsa yunifolomu adhesion wa PTFE particles pa gawo lapansi.

· 

Mitundu Yofanana Zomwe zimagwiritsidwa ntchito m'mafakitale ndizopanda ma ionic surfactants, monga Triton X  (atali-chain alkyl ether compound). Pakuwongolera konyowa, ma fluorosurfactants amagwiritsidwanso ntchito, omwe amatha kutsitsa kugwedezeka kwa emulsion pamtunda woyandikira wa zinthu za PTFE.

Maudindo Panthawi Yopangira Sintering

· 

Kuwola kwa Matenthedwe ndi Kutentha Ngakhale kuti ma surfactants ndi ofunikira panthawi yobereketsa, amakhala 'zonyansa' pomaliza. Udindo wawo mu siteji ya sintering ndikuwola motenthedwa ndi kusungunuka kwathunthu popanda kukhala mu zokutira.

· 

Sintering 'Window Phase' Njirayi imachitika nthawi yotentha ya sintering, pafupifupi 240°C , pomwe zinthu za organic zimawola ndi kusanduka nthunzi. Chifukwa chake, sintering nthawi zambiri imatenga njira yokwera pang'onopang'ono  kuti iwonetsetse nthawi yokwanira kuti mpweya wovunda utuluke, kupewa kupangika kwa thovu kapena mapini.

· 

Kuchotsa kwathunthu kwa surfactants ndikofunikira. Wotsalira aliyense wotsalira amatha kusokoneza chiyero cha zokutira, kuchepetsa zinthu zopanda ndodo komanso magwiridwe antchito a dielectric. Panthawi yomaliza yotentha kwambiri, okwera pamwamba 'amakwaniritsa cholinga chawo ndikutuluka,' kupanga njira yopangira zokutira koyera komanso wandiweyani wa PTFE.

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Material Technology Co., Ltd.

Kuti mumve zambiri pamatchulidwe, mawonekedwe ogwiritsira ntchito ndi mayankho makonda pazogulitsa zathu zonse - kuphatikiza PTFE yokutidwa ndi fiberglass nsalu, PTFE high-temperature tepi, PTFE lotseguka mauna lamba conveyor lamba, lamba makina omangira, mbali imodzi PTFE yokutidwa nsalu, mkulu kutentha zosagwira magalasi conveyor, chonde lemberani fiberglass conveyor:

Timakhala ndi malingaliro aukadaulo komanso odalirika pantchito, ndipo tadzipereka kukupatsirani mayankho okhazikika komanso ntchito zachidwi.
