Fiditaalada HDPE: Awoodda Kor, Dhaqanka iyo Nidaamka Maareynta Biyaha Kalsoonidood

Awooda saamiga leh ee tubuulka hdpe ee dhaqdhahay waxa uu ka dhacaa qorxinta kalsoonida u dhigma amaqaafsan oo ka dhiganta awoodga sare, halka la xadgudbiyo isticmaalka alaabta. Qorxintii tuubugga korosurka ah waxa uu abuura sarreefaha saamiga ee ku tegeyneysan tahay oo kala soo saara waajibaadka si hagaag leh sanjabiyaalka tuubugga, taasoo kuu kara in ay ilaaliyaan daacadaha caafimaadka sare iyo daacadaha dhulka iyagoo aan tixraaca ama aan wejifaan. Qorsheega kan muhiimka ah waxa uu sameeyaa qiimaha gaar ah ee jiritaanka halbitiga ah oo ka wayn qaabab kala duwan oo kale, halka la ilaaliyaa dhibaatada loo baahan yahay marka lagu dhisaa haaladaha shaqsi leh. Materiaalka polyethylene ee meel gaaban waxa uu sheegay awoodda weyn ee nabad galyada, taasoo kuu kara tubuulkii in ay ilaaliso nabad galyada mararka qofka, mashinkii, iyo cadhadaha aagga bilaabiyeed iyagoo aan sameyn karin shabo ama awood la'aanta saamiga. Tijaabada maancaska ah waxa muhiimka ah in tubuulka hdpe wuxuu ilaaliyaa saamiga saamiga sanjabiyaalka in ay dhiman karo ama ay wejiyaan bedelka midba midkaba, taasoo imanaya mid aad u habboon marka loo eego warshadaha, goobaha dib-u-dhexeeyinka, iyo xafiiska industriilka sare. Awoodda dhaxalka wanaagsan waxa uu sheegay awoodda weyn ee jebinta marka loo guuro ama marka loo dhisaa, taasoo kama cimri in ay wejifin karo taasoo ka dhici kara in ay dhibaato kala duwan kala duwan. Sare ugu dhexeeya tuubugga waxa uu kordhin kartaa la hadhidhka dhulka, abuuraya khatarto xidhan oo la isku hallaysa magaalooyinka dib-u-dhexeeyinka oo kordhinaya dhibaatada jiraadka iyo kala wareegista. Xasaasiikan ayaa noqonaysa muhim in ka badan goobaha dhulka hoose ama leh korontiisa sare ee biyaha dhexdooda, halka tubuulkii kala duwan kala duwan ay ka dhici karaan in ay kala wareegaan ama ay dhici karaan. Isku darka awoodga iyo dhibaatada tubuulka hdpe waxa uu kara in ay qabsi karto dhibaatada dhulka kaas oo la sababi jidhka, dhibaatada, ama dhibaatada zelzeelka iyagoo aan jointaha wejifin karo ama aan dhibaato kala duwan kala duwan. Macluumaadka aad u fiican ee shaqada ka soo baxday instalasiyadaha ee si degdeg ah ka socda labaatan iyo saddexatan sannad waxa uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu muhiimka ah in uu mu......

Sare dhagaha HDPE ay leedahay jabin dhaadhac ah oo kama guulaysan in la gadoobado ama ka halgama, taasoo xusuustooda in ay shaqeeyaan si fiican ee ku tiisnaa sharafta kor saarka ugu qabowdooda. Qaybta polimerka polyethylene ugu weyn ay leedahay jabin dhaadhac ah oo aan kaluun in la gadoobado, tuulooyin, maluul, iyo habaab-kimiyaal aadka ah ee bulshada leh dhexdaba iyo badda dhexe. Talaabada kimaayga ay sababi kartaa in la gadoobado ama ka halgama, taasoo baahinta in lagu daabo ilaa in ay ka badan tahay qaybta sare, iyadoo laga hortagi doono dadkii iyo qaab-dhismeedka kor saarista oo kale. Sare dhagaha hdpe waxay faa'iideyso leedahay warfaafintiisa, maxaa yeelay waxay jabin dhaadhac ahayd in ay horumarineysaa baabuurta, deegaankiisa, iyo sharafta tuulo ah ee dhibaatooyinka ugu horumarineysa habaab kale. Materiaalkuna ma jabin karin in la gadoobado, chloride, iyo habaabo kimaaylka aadka ah ee ku jira warshadaha iyo dibada dibadda, taasoo dhigitaanka in ay noqon kartaa in la isticmaalo dhibaatada sare dhagaha oo keliya ee kimaaylka muhiim ah. Jabin dhaadhaca heerka ogorrada ay kuu kalsooniyeen in sare dhagaha ay shaqeeyaan si fiican ee ku tiisnaa heerarka ogorrada sarreefka ah ama xad-gudubka sarreefka sare. Isbedelka UV ay naadin kartaa qaybooda la eexday sare dhagaha hdpe in ay ka halgamaan in la eexdo, iyadoo ay isku dayeen in ay kula jebin kartaa ciidamiddu iyo muuqaalka mudada dheer. Aragtida aan poro ahayn ay ilaalin kartaa horumarinta baktaariyada iyo horumarinta biofilm ee ka dhigan kartaa in ay qalbi kartaa wajiga kor saarka iyo abuurta dhabarka kor saarka hore. Jabin dhaadhaca stress kaasoo la macni jiray ay kula jibin kartaa inta ay jecelyihiin, taasoo ay isku dayeen in ay kula jibin kartaa inta ay jecelyihiin. Jarjarintii laboratoorka ee muddada dheer ay simuleeyeen muddada shaqada, taasoo tusaysa in sare dhagaha hdpe ay kula jibin kartaa afkaheerka saxda loo yaqaan. Talaabtan ay siiwanaansooraya in ka dhasho qaadasho kamid ah iyo shaqsiin kalsooni ah oo kalsooni ah hooyga iyo magaalada. Talaabta stabillimadda ayaa caawinaa in lagu tixgelinayo sidii ay ugu yartahay, maxaa yeelay sare dhagaha hdpe la isticmaalay ayaa la tixgeli karaa in ay sameyn karaan alaab cusub mana jabin karin, taasoo caawinaa in ay dhalin karaan dalkeeda iyo ka goorin karta in ay joogto.

Dhisidda haydaroolikidka ee dhilcadka hdpe ayaa heli kara awoodda koronteed ee ku qorshay dhexdha sareenka iyo joometriga inshaarka ah ee ka dhigaysa xadka gafafka lagu garta si ay ka dhigiyaan awoodda koronteed iyo kordhinta awoodda koronteed. Sareynta dhexeeya waxa ka muuqata in la astaamaha salka xad-dhab ah oo ka sii yar, taasoo ka dhigaysa in joometerkoodu kala duwan yihiin ama ka bilaabma in ay kor ugu tagaan, isku-dhafka ama horumarinta baalaha biyaha oo ka dhigaya goobta la socda iyo awoodda koronteed hadda. Aragtiyada sareenka sareenka waa muhiim ah marka loo eego falanka gaaban ee kaas oo awoodda koronteed si fiican ay ku caawiyaan awoodda koronta iyo awoodda. Tegniyadda inshaarka ayaa abuura geesood shaandheer sareen ah oo leh inshaar joometrik ah oo kordhinga haydaroolikiga, taasoo garan kara in awoodda koronteed siiso lacagteed laga yaabba in lagu dhisno geesood yar kaliya laakiin iyaga soo jeeda ilaa geesood kale oo aan joometrika sahlan. Dhilcadka hdpe oo leh geesood la istaagay waxa la abuura habeen daacad ah oo ka dhigaysa geesood istaag ah oo ka dhigaysa in biyaha buuxsado siday raadin lahayd halka la istaago sabab la’aanta sabalka oo ka dhigaya in geesuhu la cakilmo. Hababka istaagga ayaa la istaagi karaa tusaalooyinkii ah, iyadoo leh istaagooyin kala duwan oo leh geesood kala duwan, furitaanka, iyo hababka ku darsan oo kordhinga awoodda ku qabsashada sabalka kala duwan iyo baaneysa koronteed. Xaqiiqsanaanta astaahidda jabaarka sare iyo sareynta dhexeeya ayaa abuura xaqiiqsanaanshaha wanaagsan ee ka dhigaysa awoodda iyo awoodda haydaroolikiga, taasoo kordhinga awoodda jabaarka iyo awoodda koronteed. Alaabada dhejinta kompyuutar-ka lagu caawin karta injiineerada inay mudulka haydaroolikiga ee nidaamka dhilcadka hdpe ilaaliyaan, taasoo garan kara in dhisidda ay fulina maajelaha inshaarka halka la ka sarro qaladka iyo xarasha la xushma. Awoodda inshaarka saxda ah ayaa garan kara in xisaabinta haydaroolikiga ay tahay saxda intii dhexdooda, taasoo noqon kara awoodda muuqda oo taasoo caawin kara daryeelka dhererka iyo kalsooniinta nidaamka. Macaamiisha barwaaqo ee nooc walba ayaa muujin kara in dhilcadka hdpe ay ku kaydiyaan awoodda haydaroolikiga intii dhexdooda, ilaa mid walba oo aan dhexdooda ka sii badan, isla markaana alaabka kale oo kaas oo awoodda ku qaadaya si joogto ah.
