Waa maxay Cufnaanta Sare ee Polyethylene

Cufnaanta sare ee polyetylen (HDPE), budo cad ama alaab quraarad ah. Aan sun ahayn, dhadhan lahayn, crystallinity 80% ilaa 90%, barta jilicsan ee 125 ilaa 135 ° C, isticmaal heerkulka ilaa 100 ° C; engegnaanta, xoogga jilicsanaanta iyo ductility waxay ka fiican yihiin cufnaanta hoose ee polyetylen; xidho caabbinta, koronto Dahaarka Wanaagsan, adkaanta iyo iska caabinta qabow; xasilloonida kiimikada wanaagsan, aan milmin karin dareere kasta oo organic heerkulka qolka, iska caabinta daxalka ee acid, alkali iyo cusbada kala duwan; Dareemidda filimka khafiifka ah ee uumiga biyaha iyo hawada, nuugista biyaha Low; caabbinta gabowga liidata, iska caabbinta diiqada deegaanka uma fiicna sida cufnaanta hoose ee polyetylen, gaar ahaan oksaydhka kulaylka ayaa yarayn doona waxqabadkeeda, markaa antioxidants iyo ultraviolet absorbers waa in lagu daro resin si loo hagaajiyo yaraantan. Filimka polyetylen-ka cufnaanta sare leh wuxuu leeyahay kulayl yar oo qalloocan oo hoos yimaada cadaadiska, markaa fiiro gaar ah u yeelo markaad codsaneyso.

[Magaca Ingiriisiga] Cufnaanta Sare ee Polyethylene
[English soo gaabinta] HDPE
[Magaca guud] Cadaadis hoose ethylene
[Monomer Halabuurka] Ethylene

[Sifada aasaasiga ah] HDPE waa walax cad oo aan muuqan oo u eg wax u eg cufis-jiid gaar ah oo ka fudud biyaha, oo leh cuf-jiid gaar ah 0.941 ~ 0.960. Way jilicsan tahay oo adag tahay, laakiin waxyar way ka adag tahay LDPE, iyo sidoo kale wax yar la fidi karo, aan sun ahayn oo aan dhadhamin.

[Sifada guban] Waa guban karta waxayna sii wadi kartaa gubashada ka dib marka uu dabka ka tago. Cidhifka sare ee ololku waa jaale, kan hoosena waa buluug. Marka gubanaysa, way dhalaali doontaa, waxaa jiri doona dareere dareere ah, mana soo baxayso qiiq madow. Isla mar ahaantaana, waxay soo saartaa urta gubashada paraffin.

[Faa'iidooyinka ugu muhiimsan] caabbinta aysidhka iyo alkali, iska caabinta dareeraha organic, dahaarka korantada oo aad u fiican, oo wali sii ilaalin kara xoogaa adag heerkulka hooseeya. Adkeysiga dusha sare, xoogga jilicsanaanta, qallafsanaanta iyo farsamooyinka kale ee farsamada ayaa ka sarreeya LDPE, oo ku dhow PP, ka adag PP, laakiin dhammaadka dusha sare uma fiicna PP.

[khasaaraha ugu weyn] Guryaha makaanikada liidata, hawo liidata, qallafsanaanta fudud, gabowga fudud, fudud si ay u noqdaan kuwo jajaban, ka jaban PP, fudud si loo dilo dildilaaca, adkaanta dusha hoose, fududahay in la xoqo. Way adag tahay in la daabaco, marka la daabacayo, daaweynta dheecaanka dusha sare ayaa loo baahan yahay, wax koronto ah ma laha, dushana waa caajis.

[Codsiyada] Loo isticmaalo filimada baakadaha extrusion, xadhkaha, bacaha tolmada leh, shabaqyada kalluumaysiga, tuubooyinka biyaha; qaabeynta irbado ee baahiyaha maalinlaha ah ee hooseeya iyo qolofka, qaybaha aan rarka qaadin, sanaadiiqda caaga ah, sanduuqyada wareejinta; weelasha qaabaynta dharbaaxada extrusion, alaabta godan, dhalooyinka.
