Hollow yas lub rooj zaum yog dav siv nyob rau hauv ntau qhov chaw xws li tsev, chaw ua haujlwm, chaw ntau pob, thiab sab nraum zoov vim lawv qhov zoo ntawm kev sib sib zog nqus, ruaj khov, yooj yim los ntxuav, thiab tus nqi - zoo. Txawm li cas los xij, qhov zoo ntawm cov khoom lag luam sib txawv heev, thiab cov khoom lag luam tsis zoo yuav ua rau muaj teeb meem xws li kev puas tsuaj, ntxhiab tsw, thiab tsis txaus thauj khoom - cov kabmob muaj peev xwm.
Cov khoom siv yog qhov tseem ceeb hauv kev xaiv cov rooj zaum yas hollow, ncaj qha txiav txim siab lawv txoj kev nyab xeeb thiab kev ua neej nyob. Ua ntej cov khoom tsim los ntawm nkauj xwb siab - ntom polyethylene (HDPE) los yog polypropylene (PP). Cov ntaub ntawv no tsis yog - lom, ib puag ncig tus phooj ywg, thiab cuam tshuam - tiv taus. Ntxiv UV stabilizers tuaj yeem txhim kho lawv cov huab cua tiv thaiv, ua rau lawv haum rau siv sab nraum zoov. Zam cov rooj zaum ua los ntawm cov khoom siv rov ua dua tshiab. Cov khoom no feem ntau ua tiav los ntawm cov khoom siv pov tseg thiab tuaj yeem muaj cov khoom tsis zoo xws li formaldehyde. Formaldehyde tso tawm ntawm 28℃rau 24 teev tuaj yeem dhau qib kev nyab xeeb ntau zaus, ua rau muaj kev phom sij rau kev noj qab haus huv. Tsis tas li ntawd, cov rooj zaum no tsis yooj yim thiab tawg yooj yim. Txhawm rau txheeb xyuas, nrhiav cov cim rov ua dua tshiab hauv qab; tus naj npawb "2" (HDPE) lossis "5" (PP) qhia txog cov khoom siv nyab xeeb. Tsis tas li ntawd, tsw ntxhiab lub rooj zaum; cov khoom uas muaj cov ntxhiab tsw ntxhiab tsw ntxhiab yuav tsum tau muab pov tseg tam sim ntawd.
Cov txheej txheem tsim khoom thiab cov qauv tsim yog qhov tseem ceeb los ua kom muaj kev nyab xeeb siv. High-cov rooj zaum zoo hollow yas yog tsim los siv ib qho -thooj hollow tshuab moulding txheej txheem, ua rau seamless kev tsim kho, niaj hnub phab ntsa thickness (tsis pub tsawg tshaj 3 hli ntawm lub thinnest point), thiab siab sib txuas lub zog ntawm cov pob qij txha. Qhov no zoo faib qhov hnyav, feem ntau txhawb tshaj 150kg, nrog rau qee cov khoom zoo muaj peev xwm txhawb nqa 200kg. Thaum yuav khoom, maj mam nqis ntawm lub rooj zaum saum npoo los kuaj nws txoj kev ncaj ncees; cov khoom uas qhia tias tsis muaj dents, tsis muaj suab nrov txawv txawv, thiab rebound sai yog txhim khu kev qha. Tsis tas li ntawd, xyuam xim rau kev kho lub kaum sab xis; muab qhov tseem ceeb ntawm lub kaum sab xis tsim kom tsis txhob muaj cov npoo ntse thiab pob, tshwj xeeb tshaj yog haum rau cov tsev neeg nrog menyuam yaus. Yog tias lub rooj zaum muaj thav duab, xyuas cov khoom siv ncej; aluminium alloy los yog thickened steel yeeb nkab thav duab muaj zog dua thiab corrosion{10}}resistant, thiab cov pob qij txha yuav tsum tsis txhob xoob thiab burrs.
Practicality thiab saib xyuas kom meej yog qhov tseem ceeb. Xaiv qhov style zoo raws li qhov xav tau siv. Rau kev siv sab nraum zoov, tsom rau kev tiv thaiv - kev laus thiab kev ua haujlwm tsis zoo; lub rooj zaum yuav tsum muaj qhov zoo tshaj plaws kom muaj qhov dej ntws tawm kom tsis txhob muaj dej sib xyaw. Rau kev siv sab hauv tsev, ua qhov tseem ceeb ergonomic tsim uas ua raws li lub cev nkhaus kom txo tau qaug zog los ntawm kev zaum ntev. Tsis tas li ntawd, tsis yog -nplua taw taw tiv thaiv hauv pem teb thiab txo cov suab nrov thaum txav mus los, thaum cov qauv tshem tawm tau yooj yim ntxuav thiab khaws cia- cov ntsiab lus no txhim kho cov neeg siv kev paub. Tsis tas li ntawd, tshuaj xyuas cov ntaub ntawv soj ntsuam cov khoom kom paub meej tias lawv tau dhau qhov kev xeem rau kev thauj khoom -cov kabmob muaj peev xwm thiab ua haujlwm rau qhov kub thiab txias (-50℃txog 75 degree), ua kom lub neej ntev dua.
