Cov khoom sib xyaws muaj ntau qhov zoo dua li cov khoom siv ib txwm muaj. Thiab ib qho ntawm cov txiaj ntsig yog qhov yooj yim thiab ruaj khov ntawm kev kho. Cov khoom sib xyaws uas puas lawm yuav raug hloov yog tias tsis muaj kev paub txog kev kho. Tab sis qhov tseeb cov khoom sib xyaws yooj yim dua rau kev kho dua li cov khoom siv ib txwm muaj. Hauv tsab xov xwm no peb yuav muab kev nkag siab yooj yim ntawm kev kho cov khoom sib xyaws.
Kev kho cov khoom sib xyaw ua ke zoo tso cai rau peb kom ntev lub neej ntawm ib feem thiab txuag tus nqi ntawm kev hloov cov khoom sib xyaw. Muaj peb lub hauv paus ntsiab lus tseem ceeb uas yuav tsum nkag siab yog tias koj xav ua kom tiav kev kho cov khoom sib xyaw ua ke zoo. Lawv yog Kev Kho Txawv ntawm Cov Khoom Qub, Qhov Chaw Nce Nce Ua Rau Lub Zog Ntawm Kev Kho Cov Khoom Sib Xyaws Ntau Ntxiv, Kev Kho Yuav Tsum Sib Xws Nrog Koj Cov Khoom Qub.
Kev Kho Txawv Ntawm Qhov Khoom Qub.
Lub hauv paus ntsiab lus thawj zaug txog kev kho cov khoom sib xyaw uas yuav tsum nkag siab yog tias kev kho cov qauv yog ua los ntawm cov txheej txheem sib txawv ntawm daim qub. Thaum ib feem sib xyaw raug tsim thawj zaug, nws cov resin kho tau sib txuas ob qho tib si tshuaj lom neeg thiab lub cev nrog cov ntaub txhawb nqa ua rau muaj ib chav, tsis hais tus lej lossis kev taw qhia ntawm cov ntaub. Qhov no hu ua cov qauv tseem ceeb lossis kev sib txuas, thiab nws yog hom kev sib txuas muaj zog tshaj plaws uas tuaj yeem muaj nyob hauv ib feem sib xyaw.
Thaum ib feem puas lawm, txhua qhov kev kho yuav dhau los ua cov khoom sib txuas thib ob uas txuas rau cov qauv thawj. Qhov no txhais tau tias txhua qhov kev kho yog nyob ntawm kev sib txuas lub cev rau ntawm qhov chaw ntawm cov qauv thawj. Vim li no, kev kho fiberglass vam khom qhov zoo ntawm cov nplaum ntawm lawv cov resin rau lawv lub zog - lub zog ntawm kev sib txuas lub cev rau cov qauv thawj. Vim li no, cov resin siv rau kev kho yuav tsum muaj zog ib yam li cov resin siv los tsim cov khoom. Qhov tseeb, cov resins uas muaj cov khoom nplaum muaj zog qee zaum siv rau kev kho.
Thaj Chaw Nto Ntau Ntxiv Ua Rau Muaj Zog Dua Rau Kev Kho Dua Composite
Vim tias kev kho fiberglass nyob ntawm qhov kev sib txuas ntawm qhov chaw (kev sib txuas ntawm lub cev) ntawm kev kho rau cov qauv tseem ceeb, kev nce thaj tsam ntawm cov kab sib txuas yuav ua rau muaj zog thiab ruaj khov ntawm kev sib txuas - thiab los ntawm kev nthuav dav ntawm qhov lossis kev kho.
Feem ntau, txoj kev siv los ua kom thaj chaw ntawm qhov chaw ntau dua yog kev xuab zeb taper lossis scarf sanding. Hom kev xuab zeb no txhais tau tias thaj chaw ze ntawm qhov puas tsuaj raug xuab zeb maj mam, feem ntau ua rau kwv yees li ½—¾ ntawm ib nti ntawm thaj chaw ib txheej ntawm cov composite laminate. Kev xuab zeb scarf feem ntau yog ua nrog lub tshuab xuab zeb ceev ceev thiabroloc sanding discs.
Vim tias feem ntau cov qauv sib xyaw ua ke nyias nyias, qhov no yog ib qho txheej txheem maj mam. Qhov loj ntawm qhov taper, piv rau qhov tuab ntawm lub laminate, yog qhia ua piv txwv. Feem ntau, qhov kho kom muaj zog lossis tseem ceeb dua, qhov piv txwv loj dua. Kev kho cov qauv feem ntau xav tau qhov taper maj mam, nrog rau qhov piv txwv ntawm 20: 1 txog 100: 1.
Lwm txoj kev siv los ua kom thaj chaw ntawm qhov chaw loj dua yog kev xuab zeb kauj ruam. Cov txheej txheem no txhais qhov loj ntawm kev kho sab hauv, tom qab ntawd tshem tawm cov khoom siv nyob ib puag ncig ntawm qhov dav ntawm ½ "ib txheej ntawm qhov, ua haujlwm mus rau qhov chaw ntawm qhov chaw. Qhov no ua rau muaj kev loj hlob ntawm qhov chaw kho thiab tso cai rau qhov kev taw qhia fiber kom pom tseeb hauv txhua kauj ruam.
Ob txoj kev no siv tau rau feem ntau ntawm kev kho vaj tse sib xyaw, txawm hais tias feem ntau xav tias kev khi kom yooj yim dua, thiab feem ntau suav tias zoo dua. Kev taug kev ua rau cov npoo thiab cov pob qij txha hauv txhua daim ply uas kho lawm tsis meej. Nws kuj nyuaj rau taug kev xuab zeb yam tsis txiav dhau, uas yuav ua rau cov plywood hauv qab puas tsuaj.
Kev Kho Yuav Tsum Sib Xws Li Koj Qhov Khoom Qub
Txawm hais tias koj qhov kev kho composite txawv ntawm koj qhov qub, nws raug pom zoo kom koj theej qhov tuab, qhov ceev, thiab kev teeb tsa ntawm cov laminate qub thaum ua koj qhov kev kho. Qhov no yuav pab tswj kev ua haujlwm ntawm qhov. Ntau dua tsis yog ib txwm zoo dua - hauv qhov no, yog tias koj qhov kev kho yog tuab dua li qhov qub, nws yuav luag yuav tawv dua, tsis hais cov khoom siv siv. Kev qhia txog ntau yam zog hauv ib qho tuaj yeem ua rau muaj kev ntxhov siab tsis xav tau, thaum kawg ua rau cov khoom siv qaug zog lossis tsis ua haujlwm. Nws yog qhov zoo dua los hloov txhua lub ply uas tau raug tshem tawm hauv thaj chaw puas tsuaj nrog cov khoom siv zoo sib xws, muab tso rau hauv tib qho kev teeb tsa thaum ua tau. Txoj hauv kev hloov ply-rau-ply no lav tias cov qauv kho tuaj yeem tiv taus tib yam li qhov qub, thiab tias nws yuav faib cov khoom raws li xav tau.
