Iikristale ezimhlophe okanye umgubo omhlophe wekristale, onyibilikayo emanzini, utywala kunye nezinye izinyibilikisi zendalo. Isisombululo sayo samanzi sine-asidi
I-1,2,3,4-Butanetetracarboxylic acid (BTCA) yiarhente yokugqiba egqibeleleyo ye-formaldehyde-free durable press (DP). Inomsebenzi ophezulu wokuphendula kwaye ayinavumba elicaphukisayo. Icutshungulwa yi-BTCA, amalaphu afana nomqhaphu kunye nesilika anokufikelela kwiimpawu eziquka ukulwa nokuphela, ucinezelo oluhlala luhleli kunye nokugcina imo kwaye anokuqina okuphezulu.
I-BTCA ingasetyenziselwa ukulungiselela izinto ze-polyimide. Olu hlobo lwezinto lunokumelana okuhle nobushushu, ukumelana ne-asidi, ukumelana ne-hydrocarbon kunye neempawu ezilungileyo zokuthintela ubushushu, kwaye lunokusetyenziselwa ukulungiselela izinto ezahlukeneyo ze-polymer ezisebenzayo, ezifana nezinto ezibuthathaka kwi-photosensitive, izinto ze-polymer zonyango kunye nezinto ze-polymer membrane ezisebenzayo. Ingasetyenziselwa ukulungiselela iiringi zokuthintela ubushushu, ii-wire coating kunye nezinto zokuthintela ubushushu.
Ingxowa yephepha edityanisiweyo engama-25kg, eyenziwe ngePolish - linen bush okanye njengoko umthengi enqwenela.
Indawo yokugcina:
Gcina endaweni efudumeleyo nengenamoya. Ixesha layo lokuphelelwa ziinyanga ezili-12. Ingasetyenziswa nokuba sele ivuliwe.
Uthutho:
Kuphephe ubushushu obuphezulu kunye nokutshiswa lilanga ngexesha lokuthuthwa.
