Kev tshuaj xyuas cov khoom tseem ceeb ntawm HDPE Dej Trap

Hauv cov dej xa dej thiab cov kav dej, cov khoom siv ntawm cov cuab yeej dej txiav txim siab nws cov corrosion kuj, sealing kev ntseeg tau, thiab kev pab lub neej. HDPE dej ntxiab siv siab- ntom polyethylene (HDPE), cov khoom siv polymer tsim los ntawm ethylene monomers los ntawm catalytic polymerization. Vim nws qhov kev ua tau zoo tshaj plaws, nws tau dhau los ua cov khoom siv tseem ceeb rau cov khoom siv niaj hnub no thiab cov khoom siv tshuaj tsw qab.

HDPE has a dense molecular structure and high crystallinity, giving it excellent mechanical strength and rigidity while maintaining good toughness and impact resistance. Nyob rau hauv chav tsev kub, cov khoom no tuaj yeem tiv taus qee qhov kev thauj khoom sab nraud yam tsis muaj kev tawg yooj yim, thiab nws tswj tau yooj yim nyob rau hauv qis - qhov kub thiab txias ib puag ncig, zam kev tawg tawg. Qhov no ua rau nws ruaj khov nyob rau sab nraum zoov lossis ib nrab- cov dej ntws tawm sab nraud hauv thaj chaw txias. Nws qhov ceev yog kwv yees li 0.94-0.97 g / cm³, me ntsis sib dua li dej, yog li ua rau cov dej ntxiab hnyav thiab yooj yim thauj thiab nruab.

Tshuaj tiv thaiv corrosion yog lwm yam ntxwv zoo ntawm HDPE. Nws muaj kev tiv thaiv zoo heev rau feem ntau cov kua qaub, alkalis, ntsev, thiab cov organic teeb meem hauv cov kav dej phwj tuaj, thiab tsis ua rau o, tawg, lossis kev ua haujlwm tsis zoo, tso cai rau kev ua haujlwm ntev -cov dej hauv ntau qhov chaw xws li chaw nyob, tsev so, tsev kho mob, thiab chaw soj nstuam. Piv nrog rau cov ntaub ntawv hlau, HDPE tsis xeb vim cov tshuaj tiv thaiv electrochemical thiab tsis ua rau muaj kev pheej hmoo ntawm cov pa phem thib ob los ntawm txheej txheej.

Nyob rau hauv cov nqe lus ntawm kev thauj cov kua dej, HDPE tus du sab hauv phab ntsa thiab qhov chaw roughness tsawg ua rau cov dej tsis kam, txo cov av khaws cia thiab tso tawm, yog li txo qis qhov muaj feem cuam tshuam thiab txo kev tu thiab tu haujlwm. Nws zoo heev thaum tshav kub kub- fusion bonding kev ua tau zoo tso cai rau nws los tsim ib qho seamless, ib qho kev sib khi nrog cov kav dej lossis cov khoom siv ntawm cov khoom siv tib yam, tiv thaiv kom tsis txhob xau thiab txhim kho tag nrho cov kev ntseeg tau.

Tsis tas li ntawd, HDPE muaj cov txheej txheem zoo thiab rov ua dua tshiab. Los ntawm extrusion molding, U-zoo li tus los yog P- zoo li tus dej ntxiab tuaj yeem raug tsim los ua kom tau raws li cov qauv tsim rau qhov sib txawv ntawm qhov siab thiab qhov ntev ntawm cov qauv. Tom qab muab pov tseg, nws tuaj yeem rov ua dua thiab rov ua dua tshiab, ua raws li kev coj ua ntawm kev tsim kho vaj tse ntsuab thiab kev lag luam ncig.

Zuag qhia tag nrho, HDPE, raws li cov khoom tseem ceeb rau HDPE dej ntxiab, ua ke lub teeb yuag thiab siab zog, corrosion kuj, du sab hauv phab ntsa, txhim khu kev qha kev sib txuas, thiab ib puag ncig tus phooj ywg, muab cov khoom lav rau lub tsev tso kua dej uas sib txuas ua haujlwm thiab ua haujlwm ntev.
