Maxaa HDPE loo isticmaalaa?
HDPE waxaa loo isticmaalaa badeecooyinka iyo baakadaha sida weelasha caanaha, dhalooyinka saabuunta, tubbada margarine, weelasha qashinka iyo tuubooyinka biyaha.Tuubooyinka dhererkoodu kala duwan yahay, HDPE waxa loo isticmaalaa beddelka tubooyinka hoobiye ee la keenay laba sababood oo aasaasi ah.Mid, aad bay uga ammaan badan tahay tuubooyinka kartoonada ee la keenay sababtoo ah haddii qolof xumaado oo ku dhex qarxo tubbada HDPE, tuubdu ma dillaacayso.Sababta labaad ayaa ah in dib loo isticmaali karo taasoo u oggolaanaysa naqshadeeyayaasha inay abuuraan meelo badan oo la toogto.Pyrotechnicians waxay niyad jabiyaan isticmaalka tubbada PVC ee tuubooyinka hoobiyeyaasha sababtoo ah waxay u egtahay inay burburto, u dirto jeexjeexyo balaastik ah daawadayaasha suurtagalka ah, mana soo bixi doonto raajada.? -
Kaarka cagaaran ee PLA wuxuu noqdaa xal waara oo caan ah warshadaha maaliyadeed.
Baco aad u badan ayaa loo baahan yahay si loo sameeyo kaararka bangiga sannad kasta, iyo walaaca deegaanka ee sii kordhaya, Thales, oo ah hogaamiyaha amniga tignoolajiyada sare, ayaa sameeyay xal.Tusaale ahaan, kaar ka samaysan 85% polylactic acid (PLA), kaas oo ka yimid galley;hab kale oo cusub ayaa ah in la isticmaalo nudaha hawlgallada nadiifinta xeebaha iyada oo la kaashanayo kooxda deegaanka ee Parley for the Oceans.Qashin caag ah oo la ururiyay - "Ocean Plastic®" oo ah walxo ceeriin oo cusub oo loogu talagalay soo saarista kaararka;Waxa kale oo jira ikhtiyaar u ah kaararka PVC-ga ee dib loo warshadeeyay oo gebi ahaanba laga sameeyay balaastiig qashinka ah oo laga keenay baakadaha iyo warshadaha daabacaadda si loo yareeyo isticmaalka caagga cusub .? -
Falanqayn kooban oo ku saabsan xogta soo dejinta iyo dhoofinta resin pvc ee Shiinaha laga bilaabo Janaayo ilaa Juun.
Laga soo bilaabo Jannaayo ilaa Juun 2022, dalkaygu wuxuu soo dhoofiyay wadar dhan 37,600 tan oo xabagta koollada ah, hoos u dhac 23% ah marka la barbar dhigo isla muddadaas sannadkii hore, wuxuuna dhoofiyay wadar ahaan 46,800 tan oo xabagta, koror ah 53.16% marka la barbar dhigo isla muddadaas sannadkii hore.Qeybtii hore ee sanadka, marka laga reebo shirkado gaar ah oo u xirmay dayactirka, raritaanka resin-paste ee gudaha ayaa weli ahaa mid heerkiisu sarreeyo, sahayda alaabadu waa ku filan tahay, suuquna hoos ayuu u sii socday.Wax-soo-saarayaashu waxay si firfircoon u raadiyeen amarada dhoofinta si ay u yareeyaan iskahorimaadyada suuqa gudaha, iyo mugga dhoofinta dhoofinta ayaa si aad ah u kordhay. -
Sideed ku ogaan kartaa in caagtu tahay polypropylene?
Mid ka mid ah siyaabaha ugu fudud ee lagu sameeyo baaritaanka ololka waa in la gooyo muunad caagga ah oo lagu shido armaajo qiiqa ah.Midabka ololka, urta iyo sifooyinka gubanaya waxay ku siin karaan calaamad muujinaysa nooca caagga ah: 1. Polyethylene (PE) - Drips, urta sida shumaca; of candlewax; 3. Polymethylmethacrylate (PMMA, "Perspex") - Goobooyin, dildilaacyo, ur udgoon; 4. Polyamide ama "Nylon" (PA) - Olol sooty, urta marigolds; Olol sooty, urta marigolds; -

MIT: Polylactic-glycolic acid copolymer microparticles waxay sameeyaan tallaal "is-kobcinta"
Saynis yahano ka tirsan machadka Massachusetts Institute of Technology (MIT) ayaa ku sheegay joornaalka dhawaantan ee Science Advances in ay samaynayaan talaalka hal-door ah ee kor u qaada.Ka dib marka tallaalka lagu duro jidhka bini'aadamka, waxaa la sii deyn karaa dhowr jeer iyada oo aan loo baahnayn tallaal xoojin ah.Tallaalka cusub ayaa la filayaa in loo isticmaalo ka hortagga cudurrada u dhexeeya jadeecada ilaa Covid-19.Waxaa la sheegay in tallaalkan cusub uu ka samaysan yahay qaybo poly(lactic-co-glycolic acid) (PLGA).PLGA waa isku-dhismeed organic polymer ah oo shaqayn kara, kaas oo aan sun ahayn oo leh bioocompatibility wanaagsan.Waxaa loo oggolaaday in lagu isticmaalo Maqaar-galaha, tolidda, alaabta dayactirka, iwm
