Kurin Burburteed oo Labaad: Fidnaansho iyo Xasilooniyeed Abaar ah

Sare dhulka la socotay ee iskudhafka ay si degdeg ah ugu soo saara awoodda hidrooligiska adoo isticmaalaya hab dabiici dool-dool ah oo kalsoonaanayo sifada goobta, halka uu ilaalinayo jiraadda. Dabxiddu sare ee wanaagsan ku xad garta ilaa raaxadda dhexdooda marka loo bixiyo biyaha, sidoo kale waxay ka hortagaysaa shuqulkii iyo kala duwidda nidaamka dib u dhacaya geesha la socotay wareegsane. Kuwo kan arrintan waxay ku dhashaa in ka badan tahay qaar baahimadda shaqsiyadda muddo dhammaantood ee lagu dejiyey. Qaabka dib u dhacaya hoose ee sare dhulka la socotay ay abuuraan hababka goobta dadban oo ka hadlaynaya in ay ka dhigin lahaan tahay dharinta, sidoo kale ay ka dhigin tahay baahimadda saxidnimo. Albaabkan saxidnimadeed kaliya oo isku leh dharinta lama aydanaan khasabka goobta, balka qaadashada saxidnimadeed ay sabab tahay in ay isku leh tahay goobta dadban. Sare dhulka la socotay waxay ku saaraan in goobta ay joogto si degdeg ah sababtoo ah qaybta dabxiddu oo muujiyay in ay ilaaliyaan tiro guud ee goobta dhexdooda. Kan horumarinta waxay ilaalinaysaa in ay ka fog yihiin ilaa goobta ilaa raaxadda oo kale oo dhicin kara nidaamka. Muhandisiirta waxay jeclaanaysaa in sare dhulka la socotay ay ilaaliyaan goobta si cad, sidoo kale waxay ka caawin kartaa in lagu sameeyo nidaamka si cad iyo in lagu tijaabo awoodda. Faaiidaynta hidrooligiska ayaa sii socda ilaa maamulka darajada, halka awoodda sare dhulka la socotay ay ka hadlaynaya in ay ka dhigin lahaan tahay darajada oo kale oo ka dhici kara awoodda sare. Ka dhiginta kan waxay ka jeedinaysaa qaybaha hore iyo dambe ilaa xarshiga hidrooligiska, sidoo kale waxay siinaysaa nidaamka waqtiga dheer iyo in ay ka dhigin lahaan tahay baahimmo badan. Isku daynta wanaagsan waxay kaalmo sare dhulka la socotay in ay raacdaan hababka dhulka bilaashka ah iyadoo aan ku filinaya falka badan ama beddelka masirka oo kale oo ka dhici kara in ay abuurtaan raaxad dheer.

Samarada dabool ah ee dhexdhexaad ay ku lug leeyiin khaasada farxad siinaysa ilmaha sayniska iyo handisiinta oo abuuraaya xaqiiqsiga kor saaran ee jiidka aayadda. Tengidda polimer-ka wuxuu isticmaalaa polyethylene stabilized oo ka dhigan tahay in uu ilaaliyo radiationka UV, sabab uuna in laga soo bilaabo material-ka marka la aaso dhexdooda ama marka loo socdo hoos jidka. Xaqiiqsi UV-ka wuxuu garan kartaa in samarada dabool ah ee dhexdhexaad ay leedahay qalbiga iyo muuqaalka intii kula kulma karsheeda, sidaas oo aan la baahnin isku daynta laala ama qabaasho. Xaqiiqsi kiimikada wuxuu noqon yahay khaasada aynu helin samarada dabool ah ee dhexdhexaad, halkaasoo meelaha ay ka kooban yihiin asiduhu, albaashuhu, maleeshuhu, iyo kiimikadaha orgaanik ah oo badan la shaqeeya dhexdhexaadda. Qof-kolaheedka wax ugu fikirantahay xaqiiqsiga kiimikada, sidaas oo samarada dabool ah ee dhexdhexaad ay shaqeeyeen si fiican marka la aaso kiimikadaha xooggan oo kaleenaysa tuboyinka feddig si tobanbiyaha. Saamigga molekulyar ee polimer-ka loo isticmaalo samarada dabool ah ee dhexdhexaad wuxuu abuura flexibiliti aan uusan hortaga in ay kala soocdo guduudka iyo xaaladaha dushoodka. Flexibiliti-kan wuxuu ka saarisaa hababka jabinidduubka oo la shaqeeya tufooyinka shisay iyo tufooyinka silika, sidoo kale inay hubiyeen shaqada si fiican kama waaweynka jawaabka. Isbedelka kiimikada dhulka oo dhulki lagu damcen tufooyinka caadiga ah ay leedahay tani aad u yar yahay samarada dabool ah ee dhexdhexaad, sidoo kale inay hubiyeen inay la saaran tahay hal-abar kasta oo aan la baahnin isku dayn xoog badan ama meelaha la saaran. Sare ugaadhinta wuxuu ku daray tijaabooyinka sare ugaadhinta oo ay ku xusuustaa inay leedahay thickness uniform ee warshadaha iyo xaqiiqsi meelaha la isku raacayo kilaanti kasta, sidoo kale inay ka saarteen xaalado xoog badan oo kaleenaysa marnaba. Tigilinta sanadaha badan wuxuu tusaa in samarada dabool ah ee dhexdhexaad oo si sax ah loo dejiyay ay leedahay qalbiga iyo karrada orodka iyo shaqada joint sealing ee jirta iyo sanadaha 50, sidaas oo kale inay ka saarteen qiimaha beddelida iyo jilibka karsheeeda.

Nidaamka buubnaha dhexeeyinka laba-waaf ah ay iibsaan faa'iidooyin aqoonta badan adiguna ku daraystay in la saarayo nidaamka iyo habsiininta xad-dhaadhiska yar oo ka dhigaya khalinta jawaabaha projejkta guud ahaan. Qudhmin-kalaanka qalabka yar waxaa samaysaa in lagu helayso buubno dhaqdhahoodii weyn si ganacsan, ka saarita goobta sare iyo kordhinta heerarka ku jira shaqaalaha ku jira goobta saarka, iyadoo la comparenaayo saarka konkreeti ama saarka fulka. Mideyda qalabka wuxuu kala saaraa in la dhammaystiro shaqada si degdeg ah, mararka qaarkood in la dhammaystiro shaqooyinka waqtiga halba la isticmaalo cabbir kala duwan. Ilaalinta nidaamka buubnaha dhexeeyinka laba-waaf ah ay leedahay ma-aqneeya goobaha farshaxanka kala duwan iyagoo aan u baahan tahay beddellada sare ama khalkalaha boqorka aad u fiican, maxaa yeelay nidaamku wuxuu kala siiya hoosaska kala duwan. Taliyaddan wuxuu kala saaraa khalinta furfurka iyo kala duwanaanshaha dib-u-habka marka loo eego taliyada jiritaanka jiritaanka. Nidaamka ku xidhidda loo isticmaalo buubnaha dhexeeyinka laba-waaf ah ay sameynaa xidhidda daacad leh oo aan laabtin garta midho fudud iyo nidaamka caadiga ah oo aan shaqaalaha saarka u baahan tahay barasho gaar ah. Kontrolkii aasaaskii wuxuu noqon karaa fudud marka la saaro, maxaa yeelay suurtooniddu wuxuu fudud uga muujiyaa in xidhidda iyo buubnaha ay joogto si toos ah iyagoo aan u baahan tahay in la isku dayo socodka ama nidaamyo xooggan. Faa’iidooyinkii ilaaliynta nidaamka buubnaha dhexeeyinka laba-waaf ah waxaa ku jira iman la’aanta jeclaha, maxaa yeelay dhulka gacmahooda raaciyaha iyo xidhidhka kaga qaadaya ay iman la’an yihiin jeclaha laabtay oo kale oo masruufa buubnaha caadiga ah. Dhulka gacmahooda raaciyaha wuxuu kala saaraa kala qaybinta gacmaha, dharka iyo dharka midabka oo loo baahan yahay iskushubidda marwalba ee buubnaha kale, taasoo siinaya muddada u dhowaadka iyo kala saarita khalinta ilaaliynta. Marka ilaaliynta ay noqon doona muhim, meel-togga buubnaha dhexeeyinka laba-waaf ah wuxuu kala saaraa helitaanka iyo isbeddelka fudud iyagoo la comparenaayo khalkalaha qotimka ah oo sharciga badanaa in ay badaldaan qaybta guud. Isku-dhafka ama siyaasadda nidaamka ay ku xiran yihiin nidaamka buubnaha dhexeeyinka laba-waaf ah oo jira iyagoo isticmaalaya ku tilmaamaya caadiga ah iyo nidaamka xidhidda, iyagoo ka hortaga khalinta sare ee nidaamka dib-u-habka ama sharafka kala jira. Aragnimadda aqoon la’aanta wuxuu kala saaraa tallaabooyinka qiimaha muddada u dhow, taasoo kala saaraa maamulka aaladda inay budgeydaan si fiican shaqada muddada dheer ee nidaamka marka loo yaabo khalinta iskushubidda aan la taabbin lahayn oo kale oo soo baxa buubnaha kale.
