Ngaba wakha wazibuza ukuba kutheni abanye Amalaphu e-PTFE anobushushu obuphezulu anesiphelo esifana nesipili ngelixa amanye ejongeka matte okanye enziweyo? Impendulo i- calendering - inkqubo ye-post-sintering apho i-mirror mirror rollers ibeka uxinzelelo oluphezulu lwe-linear ukubuyisela umgangatho wemveliso.
Ikhalenda itshintsha ngokusisiseko i-microstructure, imeko yomphezulu, kunye nokusebenza kwenkonzo ye- PTFE ilaphu lobushushu obuphezulu . Inokunciphisa uburhabaxa bomphezulu ngomyalelo wobukhulu, itywine imingxuma emikroskopu, kwaye iphucule ngokumangalisayo iipropathi zokukhulula - kodwa ngeendleko zokunciphisa amandla okukrazula kunye nokuguquguquka.
I-Aokai PTFE isebenzisa ikhalenda ngokukhetha ngokusekelwe kwiimfuno zesicelo. Eli nqaku lichaza imiphumo emihlanu engundoqo: i-morphology yomhlaba, ukukhulula ukusebenza, ukunganyanzeki, iimpawu zomatshini, kunye nokunyamezela komlinganiselo.

Indlela esebenza ngayo: Kwiqondo lobushushu elikufutshane nendawo yokunyibilika kwe-PTFE (360–380°C), imathiriyeli ifumana impompo epheleleyo yeplastiki phantsi koxinzelelo oluphezulu. Imisonto ye-warp/weft ephakanyisiweyo iba mcaba, yenze umaleko oqhubekayo ogudileyo.
Inzuzo yolawulo lomgangatho: Iziphene zomphezulu onjengamabala ekristale kunye nokungcola zibonakala ngakumbi kwilaphu lekhalenda, zenza ukuba kuhlolwe inkangeleko engqongqo.

Kulula kakhulu - intsalela isula |
Kutheni ukukhululwa kuphucuka: Ilaphu elingafakwanga linemiqulu yefiber ephumayo eyenza ukudityaniswa koomatshini kunye nezinto ezincamathelayo, irabha, okanye intlama. Ikhalenda yenza i-PTFE eqhubekayo, umaleko ogudileyo. Iimathiriyeli zinxibelelana kuphela ne-PTFE enomgangatho ophantsi-amandla- ixobula ngaphandle komgudu phantse akukho ntsalela.
Impembelelo yesicelo: Ibalulekile ekubunjweni kwezinto ezidibeneyo (inciphisa imilinganiselo yokulahlwa), i-rubber vulcanization (inciphisa ukuhlanjululwa kwe-mold frequency), ukubhaka ukutya, kunye nokuhanjiswa kwegumbi lokucoca.
I-Aokai PTFE inikezela ngeenguqulelo ezifakwe kwikhalenda kunye nezingafakwanga kuluhlu lwamalaphu e-PTFE. Ukukhutshwa kwezicelo ze-liner apho i-zero i-residu ibaluleke kakhulu, sincoma kakhulu ilaphu le-calendered. Ukusetyenziswa okudinga amandla aphezulu okukrazula (umzekelo, amabhanti okuhambisa anomngcipheko womonakalo osemaphethelweni), angakhethwanga.
