Qhov tsis zoo ntawm HDPE yog dab tsi?
Koj hnov txog txhua yam zoo ntawm HDPE, tab sis koj paub tias tsis muaj ib yam khoom twg zoo tag nrho. Kev saib tsis taus nws qhov tsis muaj zog tuaj yeem ua rau tsis ua tiav hauv daim teb, uas yog qhov kev pheej hmoo uas koj them tsis taus.
Qhov tsis zoo ntawm HDPE yog nws yooj yim puas tsuaj los ntawm UV yog tias tsis muaj kev tiv thaiv, qhov kub thiab txias tsawg dua li cov hlau, thiab qhov coefficient ntawm thermal nthuav dav siab. Kev sib txuas kom zoo kuj xav tau cov khoom siv tshwj xeeb thiab cov neeg ua haujlwm tau kawm tiav.
Kuv ntseeg tias yuav tsum ua siab ncaj txog qhov txwv ntawm kuv cov khoom. Nws pab peb cov neeg siv khoom txiav txim siab zoo dua. Ua ntej, lub hnub ci UV tuaj yeem ua rau HDPE tawg. Peb daws qhov no tag nrho los ntawm kev ntxiv li 2% carbon dub rau peb cov kav dej siab, uas yog vim li cas lawv thiaj dub. LubCov pa roj carbon dub ua haujlwm ua lub zog tiv thaiv UV muaj zog. Qhov thib ob, HDPE tsis yog rau dej kub. Nws ua haujlwm zoo tshaj plaws hauv qab 60 ° C (140 ° F). Rau cov kua dej kub siab, lwm cov ntaub ntawv zoo dua. Qhov thib peb, nws nthuav dav thiab cog lus nrog qhov kub ntau dua li hlau. Rau cov kav dej faus, cov av tuav nws rau hauv qhov chaw. Rau cov kav dej saum av, tus qauv tsim yuav tsum suav nrog qhov kev txav no. Thaum kawg, koj tsis tuaj yeem nplaum nws lossis clamp nws. Koj xav taucov khoom siv sib xyaw ua kom sov zooTxawm hais tias qhov no yuav tsum tau pib nqis peev rau cov cuab yeej thiab kev cob qhia, nws kuj yog nws lub zog loj tshaj plaws, vim nws lav 100% tsis xau.
Kev Tswj Xyuas Cov Kev Txwv ntawm HDPE

|---|---|
| Kev puas tsuaj ntawm UV | Siv cov yeeb nkab HDPE dub uas muaj cov pa roj carbon dub rau kev tiv thaiv UV. |
| Kev Txwv Kub Qis | Tsuas yog siv rau cov ntawv thov qis dua 60 ° C (140 ° F). |
| Kev nthuav dav thermal | Xav txog kev nthuav dav/kev sib cog lus hauv kev tsim cov kab ke saum av. |
| Yuav tsum muaj cov cuab yeej tshwj xeeb | Nqis peev rau cov khoom siv fusion thiab kev cob qhia rau cov neeg teeb tsa. |
HDPE puas muaj zog dua yas?
Lo lus "yas" feem ntau zoo li tsis muaj zog lossis siv pov tseg. Koj txhawj tias kev siv cov yeeb nkab HDPE yog qhov ua rau lub zog thiab lub neej ntev. Qhov kev nkag siab yuam kev no tuaj yeem ua rau koj xaiv cov khoom hnyav dua thiab kim dua.
Qhov no yog qhov kev tsis meej pem ntau, vim HDPEisib hom yas. Txawm li cas los xij, nws yog ib hom yas engineering-grade uas muaj zog dua li cov "plastics" dav dav. Piv rau cov ntaub ntawv siv rau kev ntim khoom lossis cov khoom siv hauv tsev, HDPE muaj zog heev, ruaj khov, thiab tsim rau kev siv hnyav.
Hais tias "yas" zoo li hais tias "hlau." Lub thoob txhuas thiab lub nqaj hlau yog hlau, tab sis lawv muaj zog thiab kev siv sib txawv kiag li. Nws zoo ib yam li cov yas. Cov yas hauv lub raj mis dej pov tseg (PET) tsis zoo ib yam li cov yas hauv koj lub tsheb lub bumper (feem ntau yog Polypropylene sib xyaw), uas tsis zoo ib yam li cov yas hauv lub taub dej siab (HDPE). HDPE poob rau hauv qeb ntawm "cov thermoplastic engineeringCov no yog cov ntaub ntawv tsim tshwj xeeb los tswj kev ntxhov siab, kev nyuaj siab, thiab qhov chaw nyuaj rau lub sijhawm ntev heev. Thaum tus thawj tswj kev yuav khoom zoo li Arief teev cov yeeb nkab, nws tsis yog tsuas yog yuav "yas" xwb; nws xaiv cov khoom siv tsim kho zoo heev nrog cov yam ntxwv ua tau zoo uas sib tw lossis tshaj cov ntaub ntawv ib txwm muaj xws li cov pob zeb lossis cov hlau ductile hauv ntau daim ntawv thov.
