Lub tsheb bumpers yog dab tsi: yuav ua li cas los txiav txim cov khoom koj tus kheej
Txheem
Tsis tshua muaj, cov khoom siv thermosetting yog siv los ua cov yas rau lub bumper ntawm lub tsheb. Lawv tsis tuaj yeem ncab lossis yaj. Ntawm no, feem ntau consumables yog tsim, nyob rau hauv lub engine compartment ntawm lub engine.
Thaum kho tus kheej lub cev puas tsuaj vim yog kev sib tsoo lossis kev ua haujlwm ntev ntawm lub tsheb, cov lus nug yuav cuam tshuam rau cov tswv: dab tsi yas yog lub tsheb bumpers ua los ntawm. Qhov no yuav xav tau thaum lub sijhawm kho cov haujlwm, kho lub cev nrog koj tus kheej txhais tes.
Cov ntaub ntawv los ntawm lub tsheb bumpers yog tsim
Cov qauv tsheb niaj hnub no tau nruab nrog pheej yig yas bumpers. Xws li cov khoom siv lub cev tsis raug kev txom nyem los ntawm xeb, lawv zoo dua absorbs shocks.
Cov yas yas ruaj khov
Tshuab manufacturers siv cov thermo- thiab thermoset yas.
Thawj qhov sib txawv nyob rau hauv uas nyob rau hauv lub siab kub lawv pib yaj. Cov tom kawg tsis raug rau qhov no, uas yog, lawv tsis hloov lawv lub xeev los ntawm cua sov.
Ib qho khoom siv tsim nyog los ntawm lub tsheb bumpers yog ua los ntawm cov thermoplastic, uas yooj yim yaj, uas tso cai rau tus neeg tsav tsheb kho cov khoom siv lub cev yog tias muaj cov cim ntawm kev puas tsuaj lossis kev hnav zoo. Cov chaw kho mob rov ua dua tom qab txias.
Qee lub sij hawm cov khoom ntawm lub tsheb bumper yog sib xyaw ntawm cov yas. Los ntawm kev sib xyaw cov khoom sib txawv ntawm cov yas, tau txais cov khoom tshiab, muaj zog dua thiab tawv dua, los ntawm cov khoom siv los ntawm cov tsheb. Txhawm rau hloov kho cov tsos ntawm lub tsheb, cov neeg tsav tsheb feem ntau kho cov khoom siv lub cev: ob sab pem hauv ntej thiab nram qab. Cov txuj ci saum toj kawg nkaus hauv kev hloov pauv cov tsos ntawm lub tsheb yog kev ywj pheej ntawm kev tsim cov yas yas rau lub tsheb. Qhov no tuaj yeem ua tiav siv cov khoom siv nrov.
Polycarbonate
Polycarbonate yog ib yam khoom uas tsis muaj analogues ntawm cov thermoplastics paub. Cov khoom yog kiag li unaffected los ntawm huab cua tej yam kev mob. Nws cov khoom tseem ceeb yog siab Frost tsis kam. Lwm yam zoo:
- lub zog;
- yooj;
- lub teeb ci;
- hluav taws tsis kam;
- durability
Polycarbonate bumper
Polycarbonate muaj cov thermal rwb thaiv tsev zoo, thaum lub sijhawm ua haujlwm siab tshaj plaws yog los ntawm -40 txog 120 degrees Celsius.
fiberglass
Fiberglass hais txog cov khoom sib xyaw. Nws yog ib qho yooj yim rau txheej txheem, resistant rau kub heev. Nws yog fiberglass impregnated nrog cob. Nws muaj kev nruj heev, uas cuam tshuam rau qhov yooj yim ntawm kev teeb tsa thiab kev ua haujlwm ruaj khov: kev sib tsoo los yog maj mam kov lub laj kab rhuav tshem ib feem ntawm cov khoom siv lub cev. Nyob rau tib lub sijhawm, cov cuab yeej tsim nyog rau qhov kev sib xyaw tshwj xeeb no yuav tsum tau siv rau kev kho. Qee zaum, qhov yuav tsum tau muab khi, lwm qhov nws yuav tsum tau welded.
Fiberglass bumper
Lub cev fiberglass puas tuaj yeem kho raws li hauv qab no:
- ntxuav thiab yaug qhov chaw;
- txheej txheem cov npoo ntawm cov kab nrib pleb nrog kev tshem tawm ntawm cov xov ntawm cov khoom siv nrog lub grinder;
- dock lub ntsiab ua ke thiab kho lawv nrog kua nplaum;
- siv polyester cob rau qhov tawg;
- nteg lub fiberglass impregnated nrog kua nplaum ntawm qhov so;
- tom qab txias, grind;
- putty qhov chaw kho, degrease, prime nyob rau hauv ob peb txheej;
- pleev xim rau.
Tom qab kho, nws raug nquahu kom tsis txhob ntxuav lub tsheb hauv kev kub siab ntxuav ob peb lub lis piam.
Polypropylene
Hom yas no, hu ua "PP", yog cov yas ntau tshaj plaws rau kev tsim cov tsheb bumpers - nws muaj kev hnav siab, lub zog thiab yog qhov zoo tshaj plaws rau kev tsim cov khoom siv lub cev tshiab rau lub tsheb.
Polypropylene bumper
Cov khoom tsim los ntawm cov khoom siv elastic no nqus cov kev cuam tshuam: kev puas tsuaj tsawg heev yuav ua rau tib neeg ob txhais ceg thaum lawv raug ntaus. Yas tsis zoo adhesion rau lwm yam ntaub ntawv.
Yuav ua li cas los txiav txim seb lub bumper ntawm lub tsheb yog ua los ntawm
Yuav kom kho cov khoom siv lub cev puas zoo, koj yuav tsum paub tias yam khoom siv lub tsheb yuav tsum ua li cas. Txhawm rau ua qhov no, nrhiav cov ntawv sau npe nyob rau sab nraum qab ntawm cov yas.
Tej zaum yuav muaj lossis tsis muaj tus lej ntawm cov khoom. Hauv cov xwm txheej zoo li no, ua qhov kev sim hauv qab no txhawm rau txheeb xyuas cov yas.
Txiav ib txoj hlua nqaim los ntawm qhov chaw tsis pom kev. Ntxuav nws los ntawm cov xim, av. Muab cov yas "liab qab" tso rau hauv lub thawv dej. Yog hais tias qhov kev txiav tawm tsis mus rau hauv qab, ces koj muaj ib tug thermoplastic (PE, PP, + EPDM) - cov khoom los ntawm cov khoom siv feem ntau lub cev. Cov yas no yuav ntab rau saum npoo dej vim lawv qhov ntom ntom feem ntau tsawg dua ib qho. Cov khoom siv nrog lwm yam dab tsi hauv dej.
Lwm txoj hauv kev los txiav txim siab txog ib hom yas tshwj xeeb yog kev sim hluav taws. Ntsuas qhov nplaim taws loj, xim thiab hom pa taws. Yog li, polypropylene kub hnyiab nrog cov nplaim xiav, thiab cov pa luam yeeb muaj qhov ntse, tsw qab. Polyvinyl chloride muaj cov nplaim hluav taws kub hnyiab; thaum kub hnyiab, cov khoom siv dub, zoo li cov thee yog tsim. Qhov kev ntsuam xyuas tsis muab cov txiaj ntsig raug vim qhov tseeb tias cov khoom muaj ntau yam additives.
