Piv nrog rau thaj chaw ib txwm muaj ntawm cov tsheb siv roj, lub kaw lus EIC yog qhov tseem ceeb los sib txawv ntawm cov tsheb siv zog tshiab los ntawm cov tsheb siv roj ib txwm muaj, thiab nws tseem yog tus qauv tseem ceeb tshaj plaws los ntsuas seb lub tsheb puas muaj lub zog tawv. Nrog rau kev paub txog lub kaw lus EIC cov tsheb siv zog tshiab, daim ntawv thov ntawm nylon kuj tau hloov pauv ntau heev!
Yog li cov ntaub ntawv nylon twg tuaj yeem siv rau hauv cov tsheb fais fab tshiab?
PA46
PA46 muaj cov yam ntxwv ntawm crystallinity siab, kub tsis kam, rigidity siab, lub zog siab thiab lwm yam. Nws yog siv rau hauv lub cav tsheb thiab cov khoom nyob ib puag ncig, xws li lub taub hau lub tog raj kheej, lub hauv paus lub tog raj kheej, lub hau roj, kis tau tus mob.
PA6
PA6 muaj cov khoom siv kho tshuab zoo heev, ruaj khov, tawv, hnav tsis kam thiab nqus tau qhov cuam tshuam, rwb thaiv tsev zoo thiab tshuaj lom neeg tsis kam. Nws yog dav siv hauv cov khoom siv tsheb, hluav taws xob thiab hluav taws xob xoom thiab lwm yam teb.
· Lub hauv paus teeb liab
Cov hauv paus teeb liab nyob rau hauv thaj chaw uas muaj kev cuam tshuam thiab yog li ntawd muaj qee qhov yuav tsum tau ua rau kev tiv thaiv kev cuam tshuam thiab kev tawv, uas tuaj yeem kov yeej los ntawm kev siv PA6. Kev siv PA6 + GF hauv kev kho cov ntsia hlau lossis cov brackets kuj yog ib feem ntawm kev ua haujlwm txhua hnub ntawm cov tuam txhab tsheb.
· Cov khoom siv hauv lub tsheb
Qhov zoo tshaj plaws ntawm kev siv cov yas hauv lub tsheb chassis yog qhov hnyav txo qis. Txawm tias ntxiv cov iav fiber, PA6 qhov chaw tseem tuaj yeem sib dua li 20 txog 30 feem pua ntau dua li cov hlau txhuas, qhov hnyav qis ntawm lub tsheb tuaj yeem ua rau muaj kev siv hluav taws xob zoo dua. Thiab rau qhov qis dua ntawm lub caj npab thiab lwm yam khoom, txo qhov zoo ntawm unsprung, tuaj yeem txhim kho kev tsav tsheb zoo heev, ua rau lub cev ruaj khov dua, kev tswj hwm muaj kev nkag siab ntau dua.
· Lub plhaub them hluav taws xob
Nyob rau xyoo tas los no, muaj kev tshawb fawb ntau heev txog cov ntaub ntawv siv rau lub tsheb them lub pob. Vim tias lub pob them yuav tshwm sim hauv txhua lub sijhawm hauv lub neej txhua hnub, qhov yuav tsum tau ua haujlwm siab dua. Sab nraum zoov sab qaum teb, nws yuav tsum tiv taus qhov kub thiab txias qis; kom tiv thaiv hluav taws kub tam sim ntawd, thiab vim muaj ntau yam xwm txheej ntuj. Tsis tas li ntawd, kev ua kom lub pob them nws tus kheej thiab tiv taus qhov chaw ib puag ncig hnyav kuj yog qhov tseem ceeb tshaj plaws.
PA yog cov khoom dawb uas pom tseeb lossis tsis pom tseeb, nrog rau kev ua tau zoo tshaj plaws, txawm tias nws lub zog kho tshuab, kev tawv, kev co thiab kev hnav tsis kam, lossis nws lub peev xwm rwb thaiv hluav taws xob zoo thiab kev tiv thaiv tshuaj lom neeg, ua rau nws yog ib qho ntawm cov kev xaiv rau cov khoom siv them nqi.
PA66
Piv nrog PA6, PA66 muaj kev tiv thaiv zoo dua, tab sis qis dua qhov kev poob siab thiab kev nqus dej ntawm lub cev. Nws yog siv dav hauv tsheb, drones, khoom siv hluav taws xob thiab kev tsim hluav taws xob thiab lwm yam.
PA12
PA12 muaj cov yam ntxwv ntawm kev sib xyaw ua ke polyamide thiab polyolefin vim nws muaj ntau cov tshuaj ua kom tawv. Nws cov yam ntxwv zoo tshaj plaws yog qhov kub siab decomposition, nqus dej tsawg, thiab ua haujlwm tau zoo heev thaum kub qis.
Nws yog siv rau hauv cov kav dej roj tsheb, vaj huam sib luag ntsuas, lub pedal accelerator, lub hose nres, cov khoom siv hluav taws xob thiab hluav taws xob muffler, lub hnab cable.
PA6 uas tsis muaj halogen uas tiv taus hluav taws thiab ua kom zoo dua
Siv cov iav fiber ntau dua, cov fibers no tau teeb tsa ua ntau txoj kab, uas tsis tsuas yog ua tiav cov nplaim taws zoo, tab sis kuj phim qhov kev thauj khoom hauv cov khoom, uas tuaj yeem siv rau lub plhaub tswj hwm, kev faib, lub hau phaj thiab lwm yam khoom siab ntawm lub thawv roj teeb ntawm cov tsheb fais fab tshiab.
Cov iav fiber ntev ua rau PA6 zoo dua
Cov iav fiber ntev uas muaj zog PA6 muaj ntau yam zoo sib xws li hlau, tsim nyog rau kev tsim cov khoom siv hauv tsheb nyuaj. Piv txwv li, siv lub teeb vaj huam sib luag ntawm lub cuab yeej, lub teeb vaj huam sib luag txuas ncaj qha rau lub cev tsheb, nqa thiab xa cov khoom siv sib cuam tshuam ntawm tib neeg thiab khoos phis tawj thiab cov khoom dai kom zoo nkauj, thiab tsim lub cockpit kev nyab xeeb system nrog lwm cov khoom siv kev nyab xeeb, uas cuam tshuam ncaj qha rau kev tswj hwm thiab kev nyab xeeb ntawm lub tsheb.
Fiberglass ua rau PA66 zoo dua
Cov khoom siv nylon uas ua los ntawm iav fiber muaj lub zog siab, tiv taus kev hnav zoo, tiv taus kev xeb thiab rwb thaiv tsev zoo, thiab nws kuj siv dav hauv cov khoom ntawm lub tshuab them hluav taws xob tshiab. Cov ntaub ntawv siv niaj hnub suav nrog lub thawv roj teeb, lub tsev AC lub cev muaj zog, lub tshuab them hluav taws xob tsheb, thiab lwm yam.
Cov khoom siv fiberglass reinforced PA66 siv dav hauv kev lag luam tsheb, xws li lub cav tsheb hood, qhov rooj, vaj huam sib luag ntsuas, rooj zaum thiab lwm yam khoom. Cov khoom siv PA66 ntxiv rau iav fiber feem ntau yog: PA66 + 10% iav fiber txhim kho piv khoom siv tau rau hauv cov khoom siv sab hauv tsheb, PA66 + 30% iav fiber txhim kho piv khoom siv tau rau cov khoom siv sab nraud tsheb.
Cov iav fiber-reinforced PA66 kuj tseem siv tau ua lub tsev tswj hwm lub zog hluav taws xob - ib qho khoom uas muab lub teeb liab acceleration / deceleration raws li qhov chaw ntawm lub pedal.
PA12
Cov khoom siv yas PA12 muaj kev ywj pheej ntawm cov yas thiab roj hmab, nrog rau qhov loj me tshwj xeeb, lub zog tawg siab tshwj xeeb. Haum rau cov bellows nruj, cov roj du, cov yeeb nkab roj, lub raj nqus tsev, lub raj nres cua, cov yeeb nkab cua siab, cov yeeb nkab roj ntau txheej, cov iav ntsiag to, cov ntaub thaiv cable, cov khoom sib xyaw, thiab lwm yam.
Piv nrog rau cov yeeb nkab roj hmab, cov kab PA12 tuaj yeem txo qhov zoo ntawm lub kaw lus. Qhov ceev ntawm PA12 yog 1.02 g / cm, thaum qhov ceev ntawm EPDM roj hmab feem ntau siv hauv cov kav dej tsheb ib txwm yog 1.1 ~ 1.2 g / cm. Lub caij no, phab ntsa ntawm cov kav dej ntawm cov kab PA12 yog qhov nyias nyias. Piv txwv li, siv cov yeeb nkab nrog lub cheeb sab hauv ntawm 15 ~ 18 hli, cov yeeb nkab dej PA12 tsuas yog 1.25 ~ 1.5 hli, thaum phab ntsa tuab ntawm cov yeeb nkab roj hmab EPDM feem ntau yog 3.5 ~ 4 hli. Kev suav tag nrho, kev xaiv cov khoom siv PA12 tuaj yeem txo qhov hnyav ntawm cov kav dej los ntawm 65%. Cov qauv kav dej PA12 uas tau txais los ntawm Guangzhou Automobile Group Co., Ltd. tau txo qhov zoo ntawm cov kav dej los ntawm 56% piv rau cov kav dej hlau thiab roj hmab ib txwm muaj.
Nrog yuav luag 20 xyoo hauv kev lag luam khoom siv extrusion ntse, nws tau tuav lub luag haujlwm tseem ceeb ntawm Jwell Machinery, suav nrog Tus Thawj Coj General thiab Tus Thawj Coj Hloov Chaw. Txij li xyoo 2024, nws tau tswj hwm ntau lub tuam txhab me, tsav kev nthuav dav lag luam thiab kev txhim kho kev lag luam, thaum ua tus thawj coj hauv kev tsim khoom ntse thiab kev loj hlob thoob ntiaj teb.
