Ukulawulwa Okunembile Kwe-PTFE Coating Thickness in Fabric Production

Njengomkhiqizi womthombo ochwepheshe wendwangu ye-PTFE eshisa kakhulu, I-Jiangsu Aokai New Materials ikunikeza incazelo enemininingwane. Ngenqubo yokufaka izindwangu ze-fiber fiber (noma izindwangu ze-fiber efanayo / izindwangu) nge-emulsion ye-PTFE, umgomo wokulawula ukushuba ufana nendlela evamile yokuhlanganisa i-dip-coating. Ubunzima obukhulu bulele esakhiweni esinezimbotshana nezingalingani se-fiber substrates. Ngakho-ke, umnyombo wokulawula ukushuba ukulinganisa umthamo wokumunca uketshezi oluncane kanye nemingcele yenqubo ye-macroscopic ngokunemba okuphezulu.

1. Ifomula ye-Emulsion: Inquma ubukhulu besisekelo sesendlalelo ngasinye sokumboza

Okuqukethwe okuqinile kanye ne-viscosity : Yamukela ukuhlakazeka kokuqukethwe okuqinile okuphansi (isb. 45%) ukuze wenze uqweqwe oluncane lwephasi ngayinye futhi unciphise ingozi yokomisa ukuqhekeka. I-emulsion viscosity iyisihluthulelo sokulungisa i-fluidity kanye nenani lokuthatha i-coating.

2. Inqubo Yokukhulelwa: Ibhalansi yemishini enamandla

Isivinini sokuphakamisa / sokukhama : Ijubane linquma ukujiya kwefilimu emanzi okwakhiwa ibhalansi yamandla adonsela phansi namandla e-viscous. Isivinini esiphezulu sithwala i-emulsion eyengeziwe futhi sakha ifilimu emanzi kakhulu.

Isikhathi sokukhulelwa kanye ne-fiber pretreatment : Qinisekisa ukumanzisa okuphelele nokungena kwemicu. Ngaphambi kokukhulelwa, ama-burrs nokungcola endaweni yefayibha kufanele kuhlanzwe kahle ukuze kuqinisekiswe ukunamathela okufanayo namandla okubopha okuhle kakhulu.

I-multi-pass coating kanye nokwelashwa kwangemva kokwelashwa : Finyelela ukujiya okuhlosiwe ngokunqwabelana kancane kancane. Leli isu eliwumongo lokufinyelela ubukhulu obudingekayo, ngokuvamile obulandela umjikelezo wokukhulelwa okuningi — drying — sintering . Ukujiya okunconyiwe kwephasi elilodwa kulawulwa ngaphakathi kuka -0.01mm ~ 0.08mm.

·  Ukomisa : 100 ~ 150℃ ukususa ngokuphelele umswakama.

·  Ukubhaka : 280 ~ 290℃ ukuqeda ama-surfactants. Ukomisa nokubhaka okungalingani kuzodala imifantu, amabhamuza noma izimbobo ezimbotsheni.

·  I-Sintering : 360 ~ 390℃, ibambe imizuzwana engama-30~90. I-Sintering ibalulekile ekwakheni i-coating. Ukushisa okuphansi kakhulu kuholela ekuxhumaneni okubi phakathi kokumboza kanye ne-fiber; izinga lokushisa eliphakeme kakhulu lingabangela ukubola kwe-resin.

3. Izinto ezithinta imvelo: Izakhi ezinethonya ezibalulekile

Umswakamo : Umswakama we-ambient kufanele ulawulwe ngokuqinile ku- 40%–60% RH . Umswakama ophansi kakhulu uzodala isikhumba sobuso kanye nokungena okwanele kwangaphakathi; umswakama ophezulu kakhulu ungase ubangele ukuwohloka, izimbobo zokunamathisela kanye nokuncipha kokunamathela.

Ukuhlanzeka kwendawo yokusebenzela : Lawula ngokuqinile ukuhlanzeka kweshabhu ukuze uvimbele izinhlayiya ezihamba emoyeni ukuthi zingaweli ethangini lokukhulelwa noma ukunamathela efilimini emanzi engomisiwe, engabangela ukonakala kwendawo.

4. Iziphakamiso Ezisebenzayo Nokulawula Ikhwalithi Evaliwe

Isiqondiso sokukhiqiza : Kunconywa ukusebenzisa isu lokugxilisa okuphansi + amaphasi amaningi okufaka  ukuze ulawule ngokunembile ukushuba okuphelele kokumboza ngokulungisa izikhathi zokumilisa. Phakathi naleso sikhathi, qinisa izinqubo zokwelashwa ngaphambi nangemva kokwelashwa, okuyisisekelo sokumbozwa kwekhwalithi ephezulu.

Ukuxazulula inkinga : Uma ukuqhekeka kwe-coating kwenzeka ngemva kokucwiliswa, hlola ukuthi ukunamathela kwe-single-pass kukhulu kakhulu noma isivinini sokumisa sishesha kakhulu; uma ukunamathela kokunamathela kunganele, hlola ukuhlanzeka kwendawo ye-fiber kanye nezinga lokushisa le-sintering kanye nesikhathi sokubamba.

Ikhwalithi yesistimu evaliwe yohlelo : Sungula indlela yokukhiqiza ephelele:  Ukulawulwa kwepharamitha yenqubo → Ukuqapha kwesikhathi sangempela ku-inthanethi → Ukuhlaziywa kwezibalo zomkhiqizo oqediwe → Impendulo yokuthuthukisa inqubo .
Ukufakwa kwe-PTFE kuyinqubo eyinkimbinkimbi ye-physicochemical enokuhlanganisa okuguquguqukayo okuningi. Ukunemba kokuqina okuzinzile kungafinyelelwa kuphela ngokwakha uhlelo lokulawula olujwayelekile olumboza ifomula ye-emulsion, imingcele yenqubo kanye nezimo zemvelo, kanye nezindlela zokuhlola ezifanisiwe.
