Dab tsi ntawm cov yas yog siv nyob rau hauv cov thoob khib nyiab
Tso lus
Lub hauv paus rau phau ntawv
Cov thoob khib nyiabPuas yog hom kev siv cov khoom siv yas uas siv tau, thiab cov xwm txheej sib txawv tau sib txawv ntau rau lawv. Yog li, dab tsi ntawm cov plastics yog siv nyob rau hauv cov kaus poom thoob khib nyiab kom muaj kev ruaj khov thiab kev coj ua hauv cov chaw sib txawv? Kab lus no yuav qhia koj rau cov hom yas siv hauv cov ntawv pov tseg hauv cov cuav pov tseg, tshawb xyuas lawv cov yam ntxwv thiab cov xwm txheej muaj feem xyuam, thiab pab koj xaiv ntau cov lus qhia.
HDPE (siab - ntom polyethylene)
HDPE yog ib qho ntawm feem ntau cov yas siv rau hauv kev tsim cov khib nyiab bins. Nws yog feem ntau tsim kev siv ib - lub sij hawm txhaj tshuaj molding los, thiab yooj yim} {3} - huv huv lub cev.
Cov yam ntxwv
• Kev cuam tshuam siab kuj:Nws nruj me ntsis teem cov lwg me me tuaj yeem cuam tshuam yuam kev thaum ntaus, tiv thaiv nws los ntawm kev tawg zoo li cov ntaub ntawv brittle.
• Muaj zog corrosion:HDPE tsis muaj kev cuam tshuam nrog cov kua qaub, alkalis, noo noo, lossis ntsev, yog li nws yuav tsis corroded txawm nyob rau hauv los nag lossis noo ib puag ncig.
• Cov huab cua zoo tiv:HDPE muaj qhov zoo tsis kam rau ultraviolet rays, nag, thiab qhov kub hloov, thiab tsis muaj kev laus lossis raug rau sab nraum zoov ntev. Nws tseem nyob tawv txawm tias nyob rau hauv qis - qhov chaw nyob ntawm lub caij ntuj no, zam brittle bacthure.
Pp (polypropylene)
Piv nrog HDPE, PP yog sib dua thiab ntau dua cua sov - tsis kam. Nws yog cov khoom siv rov qab tag nrho, ua rau nws haum rau kev tsim khoom siv rov ua dua cov khoom noj.
Cov yam ntxwv
• Muaj Kub Kub Kub Tshaj:PP muaj qhov muag kub tshaj ntawm ntau tshaj 120 degree, uas tuaj yeem tiv taus dej kub yaug lossis ncaj qha tshav ntuj tsis muaj deformation.
• Kev qaug zog zoo heev:Nws cov molecular chains muaj kev rov qab elasticity, yog li thaum siv hauv Lidding cov thoob khib nyiab, lub hau yuav qhib tau thiab kaw dua tsis tau tawg.
• Tshuaj Muaj Zog:Nws muaj qhov tsis zoo rau feem ntau cov kua qaub thiab alkali daws, yog li nws tseem siv tau hauv kev cia tshuaj lom neeg lossis chaw kho mob.
PVC (polyvinyl chloride)
PVC yog cov khoom siv yas ntau nrog cov hardness. Nws cov qauv molecular muaj chlorine, muab cov nplaim taws ntuj- retardant thaj chaw. Txawm li cas los xij, vim muaj kev txwv ib puag ncig, nws yog feem ntau siv nyob rau hauv cov xwm txheej tshwj xeeb thiab tsis tshua pom nyob hauv tsev lossis chaw teeb tsa pej xeem.
Cov yam ntxwv
• Tshuaj lom neeg tsis kam:PVC tau ruaj khov molecular bonds thiab tuaj yeem tawm tsam yaig los ntawm acids, alkalis, thiab ntsev, ua rau nws haum rau ib puag ncig.
• Cov nplaim ntsuab zoo retardancy:Vim nws cov chlorine -}} muaj cov qauv, nws tuaj yeem hloov kho thaum hlawv thiab tsis yooj yim txhawb kev sib txuas.
• Hloov Hardness:Lub hardness ntawm lub cev yuav tuaj yeem hloov kho los ntawm cov kev hloov kho kom muaj kev hloov kho kom tau raws li kev siv kev pab sib txawv sib txawv.
• Yooj yim rau xim:Nws tuaj yeem kho tau rau ntau xim los pab txhawb qhov sib txawv ntawm cov hom khib nyiab sib txawv.
LDPE (tsawg {- ntom polyethylene)
LDPE yog qhov hloov tau yooj yim, lub teeb yuag yas uas yog softer dua HDPE. Nws hloov tau yooj yim tab sis tsis tshua muaj zog, ua rau nws muaj feem ntau hauv me me, lub teeb yuag cov kaus poom.
Cov yam ntxwv
• Muaj siab heev:Nws muaj kev du me ntsis thiab tuaj yeem khoov duav lossis nyem yam tsis muaj kev tawg.
• Ultra - xob laim:Nws qhov ntom ntom yog qis dua HDPE, ua rau nws sib dua thiab yooj yim los nqa txawm tias muaj lub peev xwm zoo li.
• Siv tau zoo:LDPE muaj dej tsawg vapor permeability, ua rau nws haum rau cov muag muag - lub hau khib nyiab pov tseg los ntawm chav ua noj lossis dej pov tseg.
Rov qab ua kom qhuav
Rov qab siv cov plastics yog tsim los ntawm kev ntxuav, crushing, thiab pelletizing pov tseg plastics xws li HDPE thiab PP. Lawv yog cov kev xaiv thiab ib puag ncig kev xaiv uas tuaj yeem txo tus nqi.
Cov yam ntxwv
• Kev tiv thaiv kev huam yuaj ib puag ncig ib puag ncig thiab kev lag luam:Lawv txo cov khoom siv raw thiab ua kom tau raws li cov kev xav tau ntawm kev ua kom ruaj khov.
• Durabe yog nyob ntawm raw khoom siv purity:Yog tias cov pellets rov los ntawm ib qho, kev huv los, lawv lub zog tuaj yeem ze rau ntawm cov khoom nkauj xwb; Yog tias sib xyaw nrog ntau cov plastics lossis muaj ntau yam impurities, lawv muaj feem ntau rau embrittlement thiab fading.
• Muaj mob tiv thaiv huab cua:Anti-aging agents can be added to improve performance, but long-term outdoor exposure may still cause fading or embrittlement.
Xaiv cov thoob khib nyiab tuaj yeem muab cov ntaub ntawv rau cov xwm txheej sib txawv
Cov pej xeem sab nraum zoov
Sab nraum zoov cov kaus poom yog nthuav tawm lub hnub ci, nag, thiab yuav tsum tau tiv thaiv tsis ntev, thiab kuj tseem muaj zog tiv thaiv tsis zoo lossis tus txiv neej} ua kev cuam tshuam. Yog li, cov khoom yuav tsum tau cuam tshuam - tiv taus thiab anti - kev laus. HDPE muaj cov qauv molecular nruj thiab muaj zog nruj, uas tuaj yeem tiv thaiv UV fading, thiab tiv taus dej thiab tshuaj yaig. Enlightening pallet'sYas Kev Khib Khib Nyiab Binyog ua los ntawm HDPE, ua kom ntev - lo lus ruaj khov.
Chaw ua haujlwm sab hauv tsev lossis chaw ib puag ncig
Nyob sab hauv tsev khib nyiab yuav tsum tau ua lub teeb thiab yooj yim txav, nrog tsawg chaw. Lub caij no, lub hau thiab lub cev yuav tsum tau qhib thiab kaw ntau zaus. PP thiab LDPE muaj kev nruj me ntsis thiab cov tawv nruj, tsis yooj yim rau kev siv yooj yim, thiab ua rau lawv haum, chav ua noj, lossis chav pw.
Kev lag luam lossis tshuaj ib puag ncig
Cov kaus poom pov tseg hauv kev lag luam lossis tshuaj lom neeg yuav tsum tuav cov khib nyiab uas muaj cov kua qaub, alkalis, roj, lossis lwm yam khoom sib xyaw. Kuj tseem yuav muaj kev pheej hmoo tua hluav taws thiab cuam tshuam rau cov teeb meem thaum tuav. Yog li ntawd, cov khoom yuav tsum tau corrosion - tiv taus, nplaim hluav taws xob {{retardant, thiab muaj qee yam cuam tshuam tsis kam. Ob tug pvc thiab HDPE yog corrosion - tiv taus: pvc muaj cov nplaim taws rov qab, thaum HDPE muaj kev cuam tshuam tsis zoo. Siv cov ntaub ntawv no tuaj yeem ua kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov khib nyiab hauv cov chaw muaj kev lag luam.
