Cov pa roj av muaj qhov zoo ntawm tag nrho cov polyethylene seamless (PE) sib sau ntau zaus, muaj kev cuam tshuam tsis kam, kev laus tiv taus, lub teeb heev, tsis muaj dej txia, corrosion tsis kam, lub neej ntev, ua raws li cov qauv hauv tebchaws, thiab lwm yam, cov ntsuas kev ua tau zoo dua li qub iav fiber muaj zog txhawb cov thawv yas, Lub taub hau yas vuam ntim, hlau lined yas thiab lwm yam tso tsheb hlau luam.
Tshuaj lom neeg lub cev muaj qhov kub thiab txias zoo heev thiab ua haujlwm txias, muaj zog, tensile lub zog, antistatic zog thiab ductility zoo heev, thiab muaj cov roj ntsha zoo heev, yeej tsis yaj txhua lub siab kub ntawm chav kub ua kom muaj kuab tshuaj, tiv taus txhua hom kua qaub, alkali thiab ntsev ua kua corrosion, kuj muaj qhov zoo tiv thaiv shear kev nyuaj siab tawg thiab vuam kev ntxhov siab tawg ua tus yam ntxwv, siab zog lub zog, zoo specification kev ntseeg tau. Cov pa roj carbon monoxide yog ib qho yooj yim siv thiab yig. Nrog rau kev hloov kho tshiab thiab hloov pauv, cov thoob yas tau maj mam dhau los ua cov khoom tseem ceeb ntawm cov kua ntim. Nws tuaj yeem tuav cov khoom Class thiab Chav Kawm III qhov khoom txaus ntshai. Lub zog ua kua ntawm Class goods cov khoom txaus ntshai yog 1.5g / cm3, thiab cov kua hluav taws xob ntawm Cov Khoom Muaj Teeb Meem - yog cov khoom txaus ntshai yog 1.8g / cm3. Cov khoom lag luam yog cov tsim nyog, kev kho kom ruaj khov thiab ruaj khov, tuaj yeem tawm los ntawm stacker tam sim ntawd, thiab tuaj yeem khaws cia rau kev khaws cia.
Cov thawv ntim khoom hnyav yog lub teeb taws thiab tsis tawg yooj yim. Cov thoob yas, cov tais thiab cov fwj hauv kev lag luam chemical uas feem ntau tuav cov zaub mov feem ntau yog ua los ntawm polyethylene lossis polypropylene, uas polyethylene muaj ntau dua. Polyethylene kuj tuaj yeem tsim ntim rau hauv cov thoob xws li cov thoob thiab cov lauj kaub, tab sis nws yog tib yam li cov yeeb yaj kiab. Nws tsis tuaj yeem muaj cov khoom noj nqaij, tshwj xeeb tshaj yog thaum nws tsis raug tso cai cia cov roj thiab cawv txiv hmab. Tseem muaj cov mem tes aldehyde plastics nrog cov lej cuav" Dianyu" thiab sodium thiocyanate methylaluminium nrog rau lub npe cuav" Melamine" ;. Cov ntaub ntawv raw nqa formaldehyde. Thaum lub sijhawm ua, yog tias ntxiv polymerization tsis zoo, cov ntxhia kua qaub aciddehyde yuav tshwm nyob rau hauv cov tais diav hauv chav ua noj. Formaldehyde yog ib qho khoom siv organic nrog muaj zog phiv. Yog tias nws txeem rau hauv cov nqaij, nws yuav ua rau muaj kev phom sij rau lub cev kom tsis muaj mob. Yog li ntawd, nco ntsoov siv cov khoom zoo" hluav taws xob jade" thiab" melamine" chav ua noj thiab tej tais diav. Rau cov khoom lag luam tsis tsim nyog, kev tiv thaiv ib puag ncig yuav tsum nruj saib xyuas thiab zam kev tshwm sim. Txawm hais tias polyethylene tais diav tuaj yeem siv los tuav cov zaub mov, lawv kuj yuav tsum tau siv roj. Vim tias polyethylene dissolves rog, yog tias nws tau khaws cia ntev, xim thiab saj ntawm kev ua noj roj yuav hloov ntau heev, thiab txawm tias nws tsis tuaj yeem noj, uas tsis zoo rau kev noj qab haus huv.
