20-kii sano ee la soo dhaafay, tuubooyinka caagagga cusub ayaa si weyn looga isticmaali jiray degmooyinka, gaaska iyo goobaha biyaha laga qaato. Gaar ahaan hagaajinta joogtada ah iyo hal-abuurnimada tignoolajiyada polymerization polyetylen, waxaa jira qalab koronto oo xoog leh oo sii kordhaya. Si loo sii ballaadhiyo heerarka cadaadiska ee tuubooyinka caagga ah, gaar ahaan sannadihii la soo dhaafay, iyada oo loo marayo cilmi-baarista tiknoolajiyada isku-dhafka ah, tignoolajiyada isku-dhafka birta-caaga ah ee la soo bandhigay ayaa si guul leh u xalliyey dhibaatooyinka tuubooyinka polyetylen (PE) marka loo eego heerka cadaadiska, ka hortagga. daxalka, iyo dhexroor wareegga wax ku ool ah. Loo adeegsaday codsiyo gaadiid oo dareere ah oo kala duwan.
Qaab dhismeedka: Alaabtani waa jir la xoojiyey oo leh lakab xudun ah oo si joogto ah u dhaawacan silig bir ah oo xoog badan ka dib daaweynta daahan, iyo koollo kulul oo gaar ah iyo balaastig ah ayaa lagu daraa tuubo dhan iyadoo loo marayo habka qaabaynta extrusion.
Waxqabadka dhaqaalaha ee dhuumaha
Isticmaalka polyetylen cufnaanta sare sida walxaha lakabka gudaha iyo dibaddaba, birta mesh qalfoofka polyetylen caag ah oo isku dhafan ayaa leh waxqabadka ugu fiican ee alaabta tuubooyinka polyetylenka. Sababtoo ah saameynta qalfoofka birta, tuubada isku dhafan ee heerka cadaadiska isku midka ah ayaa leh dhumuc yar oo gidaar ah oo ka yar tuubooyinka caaga ah ee saafiga ah. Wareegga wax ku oolka ah ee агеа waa ka weyn yahay, iyo iska caabin daxalka wanaagsan iyo xidhashada iska caabin ah si loo hubiyo in nolosha adeegga ee tuubada сап bе sida lang sida 50 sano, taas oo si wax ku ool ah u wanaajisaa waxqabadka dhaqaale ee dhuumaha.
Xooji qalfoofka si aad si wax ku ool ah u xakamayso dildilaaca
Isticmaalka lakabka xudunta u ah mesh birta ah ee xoogga badan sida а xoojinta qalfoofka si wax ku ool ah u joojiya wax soo saarka dildilaaca joogtada ah iyo faafinta degdega ah ee maaddooyinka polyetylenka, waxayna leedahay xoog cadaadis sare leh (cadaadiska magaca ee dhuumaha biyaha ayaa gaaraya З.5МРа) iyo shisheeye сгеер iska caabbinta, iska caabin sare oo saameyn leh, iyo tilmaamayaasha waxqabadkiisa ayaa ka sarreeya tubooyinka polyetylenka.
