Cov Khoom Noj Khoom Haus thiab Qib Kev Lag Luam Roj Hmab Hose
Kev Qhia Txog
1. Cov qauv hose feem ntau muab faib ua peb pawg raws li nram no:
1.1 Cov roj hmab hose nrog cov qauv txheej txheem txhawb nqa
1.1.1 Cov yeeb nkab roj hmab uas muaj ntaub ua kom ruaj khov
1.1.2 Cov kav dej roj hmab uas muaj hlau txhawb nqa
1.1.3 Raws li cov qauv ntawm cov txheej txheem txhawb nqa
1.1.3.1 Cov yeeb nkab roj hmab laminated: cov yeeb nkab roj hmab ua los ntawm cov ntaub coated (lossis cov ntaub roj hmab) ua cov khoom siv txheej pob txha, tuaj yeem kho nrog cov hlau hlau sab nraud.
Cov yam ntxwv: cov ntaub qhwv lub raj xa dej siab feem ntau yog ua los ntawm cov ntaub woven yooj yim (nws qhov ceev thiab lub zog ntawm warp thiab weft yog qhov zoo ib yam), txiav los ntawm 45 °, splicing, thiab qhwv. Nws muaj qhov zoo ntawm cov txheej txheem tsim khoom yooj yim, muaj zog hloov kho tau raws li cov lus qhia ntawm cov khoom thiab ntau txheej, thiab lub cev yeeb nkab zoo. Tab sis nws tsis ua haujlwm zoo.
1.1.3.2 Cov roj hmab braided hose: cov roj hmab hose ua los ntawm ntau yam xov hlau (fiber lossis hlau hlau) raws li txheej pob txha hu ua braided roj hmab hose.
Nta: Cov txheej braided ntawm cov hose braided feem ntau yog interwoven raws li lub kaum sab xis (54 ° 44 '), yog li cov hose ntawm cov qauv no
Nws muaj kev ua tau zoo ntawm kev coj tus kheej, kev ua tau zoo ntawm kev khoov thiab kev siv cov khoom siv siab piv rau cov roj hmab laminated.
1.1.3.3 Cov yeeb nkab roj hmab uas ntswj: Cov yeeb nkab roj hmab uas ua los ntawm ntau yam xov hlau (fiber lossis hlau hlau) raws li txheej pob txha hu ua cov yeeb nkab roj hmab ntswj. Cov yam ntxwv: zoo ib yam li cov yeeb nkab braided, lub zog siab, kev cuam tshuam thiab kev ua haujlwm zoo flexure. Kev ua haujlwm ntau lawm.
1.1.3.4 Cov yeeb nkab uas siv rau xaws: cov yeeb nkab uas ua los ntawm cov xov paj rwb lossis lwm cov xov ua cov txheej pob txha hu ua cov yeeb nkab uas siv rau xaws.
Cov yam ntxwv: xov xov yog interwoven rau ntawm lub raj sab hauv billet ntawm ib lub kaum sab xis nrog lub ncej. Qhov kev sib tshuam yog tsawg thiab feem ntau muaj ib txheej txheej.
