II Prìomh Bhuannachd agus Iarrtas
A. Paramadair corporra:
1) Trast-thomhas uèir: 0.025 ~ 15mm
2) Tha comas aig nicil fìor-ghlan seasamh ri teòthachd an ìre mhath àrd gun chrìonadh. Obrachadh as àirde
tha an teòthachd timcheall air 600 ° C
3) Tha uèir nicil ri fhaighinn ann an togail aon shreath no ioma-iallan. Tha e air a thoirt seachad bho stoc an dara cuid lom, no air a chòmhdach
B. Feartan:
1) Sàr-cheartas
2) Suidheachadh uachdar èideadh agus breagha gun spotan
3) Sàr chomas cruth coil
C. Prìomh thagraidhean agus adhbhar coitcheann:
1) Faodar an uèir seo a chleachdadh gu farsaing cuideachd san fharsaingeachd air a shònrachadh airson caiptean transistor, anodes airson tiùban dealanach,
stiùiridhean de cho-phàirtean dealanach / uèirichean luaidhe airson lampaichean agus airson mogal-uèir. Cuideachd air a chleachdadh ann an cruth stiallan airson diofar
tagraidhean a’ toirt a-steach bataraidhean Ni-Cd
2) Cuideachd air a chleachdadh airson càbaill, Lead-in-Wire airson lampaichean, taic tiùba dealanach, uèir ceangail dealain uèir
far a bheil an teòthachd nas àirde na an fheadhainn airson a bheil copar freagarrach, fighe uèir
3) Am measg nan tagraidhean àbhaisteach tha: crìochnachadh airson eileamaidean teasachaidh mar ann an àmhainnean, extruders plastaig, fùirneisean.
