Izicelo eziphambili kwiShishini

Ukwenziwa kweGlasi

Eyona ndlela inzima yokusebenzisa iibhanti zeKevlar ezishushu kakhulu. Iibhanti zithutha izinto zeglasi eshushu—i-stemware, iifestile zomatshini wokuhlamba impahla, izitya zetafile—ukusuka ekwenzeni ii-presses ukuya kwi-annealing lehrs, apho amaqondo obushushu aphezulu kwaye ukutshayiswa kobushushu kuyingozi engapheliyo. Ukumelana nobushushu bebhanti kuthintela ukuphawulwa, ukugqwala, okanye ukuguquka kwemiphezulu yeglasi.

Ukwenziwa kweMetallurgy kunye neNtsimbi

Ukuhambisa amaphepha esinyithi ashushu, ii-castings eziweldiweyo, i-ore e-sintered, kunye ne-clinker. Kwizityalo zentsimbi, iibhanti zeKevlar ziphatha izinto ezishushu ezivela kwiinkqubo zokuphosa eziqhubekayo okanye ze-galvanizing, zigcina ukuthembeka apho iibhanti zerabha eziqhelekileyo ziya kuqina kwaye ziqhekeke. Iibhanti zeSuper-K® ezisekwe kwi-EPDM lolunye ukhetho olumelana nobushushu, kodwa iKevlar inika amandla okutyhafa angcono kunye nolwakhiwo olukhaphukhaphu.

Imigodi kunye noShishino oluNzima

Iibhanti zokuhambisa imithwalo zemigodi ezinee-Kevlar® carcass zithatha indawo yeebhanti ze-polyester/nylon kunye neentambo zentsimbi eziqhelekileyo. Iingenelo ziquka ixesha elide lokuphila, ukuncipha kokumelana nokuqengqeleka, ukusetyenziswa kwamandla okuphantsi, kunye nee-slices ezimbalwa. Uyilo olulula lunciphisa iimfuno zesakhiwo sezixhobo kunye neendleko zokusebenza.

Imisebenzi yokomisa nokunyanga

Iibhanti ze-Kevlar mesh ezigqunywe yi-PTFE zisetyenziswa kwezi:

• Ii-dryer zelaphu ezisicaba kunye nemigca yokufunxa
• Iitonela zokunyanga ezikude ze-infrared
• Ii-oveni zokomisa ze-PCB
• Imigca yokuphelelwa ngamanzi emzimbeni kwimizi-mveliso
• Ukupakisha i-lamination kunye nokuseta ukuncipha kwengubo

Uyilo lwe-mesh evulekileyo luvumela ukuhamba komoya ngelixa umphezulu we-PTFE onganamatheliyo uqinisekisa ukukhululwa kwezinto ngokulula.
