Ainm Táirge | 304 Boltaí Ceann Heicse Cruach Dhosmálta |
Ábhar | Déanta as 304 cruach dhosmálta, tá friotaíocht ceimiceach maith ag na scriúnna seo agus féadfaidh siad a bheith beagán maighnéadach. Tugtar cruach dhosmálta A2 orthu freisin. |
Cineál Ceann | Ceann Heics. |
Fad | Déantar é a thomhas ó faoi cheann. |
Cineál Snáithe | Snáithe Garbh, Snáithe Míne. Is iad snáitheanna garbh an caighdeán tionscail; roghnaigh na scriúnna seo mura bhfuil an pháirc nó na snáitheanna in aghaidh an orlach ar eolas agat. Tá spásanna dlúth idir snáitheanna míne agus seach-mhínithe chun cosc a chur ar scaoileadh ó chreathadh; dá míne an snáithe, is amhlaidh is fearr an fhriotaíocht. |
Caighdeán | Comhlíonann scriúnna a chomhlíonann sonraíochtaí ASME B18.2.1 nó roimhe seo DIN 933 na caighdeáin tríthoiseach seo. |
Faigheann boltaí heics cruach dhosmálta iarratais fhorleathan ar fud na dtionscal éagsúla mar gheall ar a n-friotaíocht creimeadh, neart agus marthanacht. Ceadaíonn an ceann heicseagánach é a cheangal go héasca le eochair nó soicéad. Seo roinnt feidhmchlár coitianta le haghaidh boltaí heicsidheachúlach cruach dhosmálta:
Feidhmchláir Mhara:
Tá boltaí heicsidheachúlach déanta as cruach dhosmálta resistant a chreimeadh, rud a fhágann go bhfuil siad oiriúnach le húsáid i dtimpeallachtaí mara le haghaidh tógáil agus deisiú bád.
Earnáil Ola agus Gáis:
Úsáidtear boltaí heicsidheachúlach i dtógáil agus i gcothabháil rigí ola, píblínte agus bonneagair eile sa tionscal ola agus gáis.
Innealra Talmhaíochta:
Úsáidtear é i ndéantúsaíocht trealaimh agus innealra talmhaíochta, amhail tarracóirí agus céachta.
Tionscadail Fuinnimh In-athnuaite:
Úsáidtear boltaí heicsidheachúlach i dtógáil tuirbíní gaoithe, struchtúir painéil ghréine, agus bonneagar fuinnimh in-athnuaite eile.
Áiseanna Cóireála Uisce:
Úsáidtear boltaí heicsidheachúlach i gcóimeáil agus i gcothabháil ionaid chóireála uisce, ag cinntiú naisc shlána i dtrealamh agus i struchtúir éagsúla.
Próiseáil Bia agus Dí:
Tá boltaí heicseagán cruach dhosmálta oiriúnach don tionscal bia agus dí mar gheall ar a bhfriotaíocht creimeadh, a úsáidtear i gcóimeáil trealaimh phróiseála.
HVAC (Téamh, Aeráil, agus Aerchóiriú):
Úsáidtear é i suiteáil agus cothabháil córas HVAC chun comhpháirteanna agus struchtúir a dhaingniú.
