DIN 30670-1 Hordhac

DIN 30670-1waa geedi socod saddex lakab ah oo soo saara polyetylen3LPE) dahaarka dusha sare ee dhererka ama silig alxanka leh iyotuubooyinka birta ah ee aan lahaynsi looga ilaaliyo daxalka.

Waxaa inta badan loo adeegsadaa habka dhuumaha ee la aasay ama la quusiyay si loogu qaado dareeraha ama gaaska.

Fiiro gaar ah: DIN 30670 ayaa loo qaybiyay laba qaybood daabacaadda 2024 ee ugu dambeysay iyadoo kuxiran habka wax soo saarka, kuwaas oo kala ah DIN 30670-1 waxay dabooshaa tuubada iyo boogaha dahaarka polyetylenka, iyo DIN 30670-2 waxay daboolaysaa noocyada kala duwan ee dabka iyo ololka lagu buufiyo.

Noocyada Qaybta

Waxay u qaybsan yihiin laba nooc iyadoo loo eegayo heerkulka naqshadeynta, kuwaas oo ahnooca N iyo nooca S.

Nooca Heerkulka naqshadaynta (°C)
N -20 ilaa +60
S -40 ilaa +80

iyoISO 21809-1u dhiganta fasalka A iyo fasalka B, siday u kala horreeyaan.

Qaybaha Nidaamka Dahaarka

Lakabka 1aad ee Epoxy resin, budada resin epoxy waa in la isticmaalo.

Lakabka 2aad ee xabagta, kaas oo noqon kara budo ama dahaarka dibadda loo saaray.

Lakabka 3aad ee Polyethylene, habka extrusion tube, ama habka dabaysha.

Dhuunta Tubada:
Habkan, walxaha polyetylenka ayaa si toos ah loogu sii daayaa qaab tuubo ah oo joogto ah, kaas oo markaa lagu dhejiyo tuubada birta ah.
Habkan waxaa sida caadiga ah loo isticmaalaa tuubooyinka dhexroorka yar oo hubiya isku mid ahaanshaha iyo sii wadida dahaarka.
Dabaysha dabaylaysa:
Habkan, polyetylen-ka ayaa la soo saarayaa qaab xariijimo ah ka dibna ku dhaawacan dusha tuubada birta.
Habkani wuxuu ku habboon yahay tuubooyinka waaweyn ee dhexroorka ama kuwa aan caadiga ahayn waxayna u oggolaanayaan dahaarka dabacsan ee tuubooyinka adag ama kuwa waaweyn.

Dahaarka Dheeraadka ah

Iyadoo ku xiran baahida gaarka ah ee mashruuca, lakabka dheeraadka ah ee ilaalinta farsamada ayaa lagu dari karaa 3LPE.

Qalabka sida caadiga ah loo isticmaalo waxaa ka mid ahla taaban karo(Tixraac ISO 21809-5),caag lagu xoojiyay fiber-ka galaas, ama hoobiye sibidhka(tixraac DN N 30340-1).

Si loo hubiyo xoogga dhogorta wanaagsan, waxaa lagama maarmaan ah in la qallajiyo ama la cadaadiyo dusha sare ee polyetylen.
Daaweynta noocan oo kale ah waxay gacan ka geysaneysaa kordhinta isku-xirnaanta u dhaxaysa lakabka difaaca dheeraadka ah iyo daboolka polyetylen.

Wadarta Dhumucda Dahaarka

Iyada oo ku xidhan dhexroorka magacaaban ee tuubada birta, dhumucda lakabka ilaalinta daxalka way ka duwanaan doontaa.

Wadarta dhumucda lakabka 3LPE, DIN 30670-1 waxay u qaybisaa saddex fasal si ay ula qabsadaan shuruudaha dhismaha ee kala duwan.n,v, iyo s.

DIN 30670-1 Wadarta dhumucda dahaarka

Darajada nXaaladaha caadiga ah, dhumucda darajada n ayaa inta badan ku filan.
Dahaarka polyetylenka, dhumucdiisuna tahay 1 mm ayaa ugu horrayn loo isticmaalaa ilaalinta daxalka, halka dhumucda soo hadhay loo isticmaalo si kor loogu qaado awoodda culeyska farsamada ee lakabka ilaalinta.

Darajada v: Haddii culeyska farsamada uu kordho (gaadiidka, kaydinta, dhigista, tayada gaarka ah, shuruudaha kordhay), dhumucda ugu yar ee daahan waa in lagu kordhiyo 0.7 mm, ie v = n + 0.7 mm.

Darajada s: Dhumucda daahan gaarka ah ee ka sarreeya v ayaa sidoo kale lagu heshiin karaa si loo daboolo baahida mashruuc gaar ah, iyo dhumucdiisuna dahaarka sida habaysan lagu calaamadeeyay sida Grade s.

Goynta

150mm ± 20mm, xagasha bevel ee dhumucda daahan waa in aan ka badnayn 30 °.

Lakabyada epoxy-ga iyo koollada waa in laga saaraa ugu yaraan 80 mm dhammaadka tuubada.Lakabka epoxy-ga waa in looga tagaa isagoo ka soo baxaya dhamaadka tuubada polyetylen-dahaarka leh oo aan ka yarayn 10 mm.

Si loo go'aamiyo dhererka, qiyaas laga bilaabo dusha sare ee tuubada ilaa bilowga jeexan geesaha ee lakabka ilaalinta daxalka.
