Cov rooj zaum hauv chaw ntau pob
Cov rooj zaum hauv chaw ntau pob tuaj yeem ua tau raws li qhov xav tau ntawm ntau qhov chaw huab cua thoob ntiaj teb, suav nrog sab hauv tsev, sab nraum zoov, kub, av noo, thiab tshuaj tsuag ntsev. Qhov no muaj feem xyuam nrog lawv cov qauv, cov khoom siv, thiab cov txheej txheem tsim khoom. Hauv qab no yog cov lus qhia ntxaws:
Lub Cev Lub Cev: Ua los ntawm siab -density polyethylene (HDPE) nrog qhov ceev ntawm 0.95-0.97 g/cm³, tensile zog Ntau dua los yog sib npaug rau 25 MPa, elongation ntawm tawg ntau dua los yog sib npaug li 600%, thiab cuam tshuam lub zog siab dua los yog sib npaug rau 15.m² / k Nws toughness thiab lub zog deb tshaj li cov khoom zoo tib yam. Nws suav nrog siab -kub antioxidants, nplaim taws retardants, antistatic agents, thiab huab cua- tiv taus masterbatches. Kev ntsuam xyuas kev laus sab nraum zoov yog ntau dua lossis sib npaug li 3500 teev, thiab nws tiv taus qhov kub thiab txias ntawm -60℃rau +80℃. Tom qab 72 teev ntawm qhov chaw kuaj huab cua, nws pom tias tsis muaj deformation lossis tawg. Nws ua tau raws li cov qauv thoob ntiaj teb ib puag ncig, tsis yog - tshuaj lom, tsis muaj ntxhiab, tsis muaj formaldehyde, thiab tsis muaj hlau hnyav, ua rau nws tsim nyog rau cov chaw pej xeem.
Hollow tshuab moulding: Los ntawm sab nraud, cov rooj zaum hauv chaw ntau pob nthuav tawm tag nrho, nrog rau qhov tsis sib haum xeeb, cov phab ntsa tuab, thiab sab hauv cov txheej txheem kev txhawb nqa, uas ua rau muaj txiaj ntsig zoo rau kev thauj khoom -cov kabmob muaj peev xwm. Qhov saum npoo yog du thiab burr-dawb, nrog cov nkhaus du thiab xis nyob, thiab nws muaj cov dej tsis zoo, tsis muaj pov thawj- pov thawj thiab yooj yim- rau- huv si.
Thaum lub sij hawm tsim cov rooj zaum hauv chaw ntau pob, peb tsis tsuas yog tswj xyuas qhov zoo xwb tab sis kuj ua tiav cov khoom tiav tiav. Tsuas yog cov khoom tsim nyog tau tso cai tawm hauv lub Hoobkas, tsis lees txais cov khoom lag luam qis dua los ntawm qhov chaw thiab qhia peb lub luag haujlwm rau peb cov neeg siv khoom. Cov khoom kuaj tseem ceeb ua ntej xa zaub mov muaj xws li cov hauv qab no:
Static load test:Siv 2000N ntawm siab rau lub rooj zaum thiab 800N ntawm lub siab rau lub backrest, thiab xyuas kom meej tias tsis muaj deformation, tawg lossis loosening tom qab 1 teev;
Dynamic impact test:Ib qho 80kg rauj tau siv los cuam tshuam lub rooj zaum saum npoo los ntawm qhov siab ntawm 360mm thiab backrest los ntawm qhov siab ntawm 630mm. Tom qab 20 lub voj voog ntawm kev sim, tsis muaj kev puas tsuaj lossis tawg.
Kev ntsuas kub thiab qis:-60℃khov rau 72 teev → +80℃ci rau 72 teev, tsis muaj deformation, tawg lossis fading tshwm sim;
Aging Resistance Test:Tom qab 3500 teev ntawm UV aging chamber kuaj, qhov sib txawv ntawm cov xim yog tsawg dua los yog sib npaug rau 1 qib, thiab qhov saum npoo tsis pom cov cim ntawm embrittlement lossis hmoov.
Kev tshuaj xyuas qhov loj:Length, dav thiab qhov siab yuam kev Tsawg dua los yog sib npaug rau ± 2mm, nto tsis muaj khawb, npuas, shrinkage marks thiab flash, xim xim tsis muaj xim sib txawv thiab zoo ib yam gloss.
Cov duab ntxaws ntxaws ntawm cov rooj zaum grandstand
High-density polyethylene (HDPE) has a linear molecular chain structure with few and short branches, and its chain segments are arranged regularly and densely, thus giving it high rigidity, high strength, and good heat resistance. Nws muaj cov khoom zoo thermal zoo:
Melting point: 131-137 degree;
Softening point: 125-135 degree;
Nws tuaj yeem siv rau ncua sij hawm hauv ib puag ncig Tsawg dua lossis sib npaug li 80 degree, yog lub teeb yuag tsis tau siab -lub zog, thiab ruaj khov.
Cov rooj zaum hauv chaw ntau pob tsis tawg, tawg, lossis dhau mus tas li deformation nyob rau hauv cov khoom hnyav xws li kev cuam tshuam sab nraud tam sim ntawd, ntog khoom hnyav, neeg coob coob, kev sib tsoo hnyav, thiab kev sib tsoo nrog cov khoom tawv.
Cov neeg yuav khoom los ntawm Russia, Kyrgyzstan thiab Kazakhstan txaus siab heev rau peb lub rooj zaum.Los ntawm lub Hoobkas kos npe rau daim ntawv cog lus thiab tsim cov phiaj xwm.
Cov rooj zaum hauv chaw ntau pob yog cov txheej txheem nyuaj uas muaj lub cev loj, ncej, thiab kev sib txuas. Cov ncej hlau yog lub hauv paus tseem ceeb uas tiv thaiv tag nrho cov kev cuam tshuam thiab tiv thaiv kev tawg. Lawv tau tsim los siv hwm Q355B qis- alloy siab- lub zog steel nrog lub zog tawm los Ntau dua lossis sib npaug rau 355MPa, nce kev cuam tshuam thiab deformation tsis kam los ntawm 40%. Kev ua haujlwm siab ntawm CO2 shielded welding yog ua haujlwm, ua rau cov welds tsis muaj porosity thiab slag inclusions, nrog lub zog vuam ntau dua lossis sib npaug li 90% ntawm cov khoom siv hauv paus. Cov khoom sib txuas siv 304 stainless hlau bolts, uas yog shear{12}}tiv taus, cuam tshuam- tiv taus, xeb{14}}dawb, thiab tiv thaiv kom tsis txhob xoob, ua kom cov rooj zaum tsis tawg thaum muaj kev cuam tshuam.
