Hmoov txheej yog txheej txheem txheej txheej hlau nrog cov yas ua tiav rau hauv cov hmoov thiab ci rau hauv cov kua dej kom sib txuas rau cov hlau. Hmoov txheej muaj ntau qhov zoo tshaj li ib txwm ua kua txheej: Nws zoo dua rau ib puag ncig, siv tuab dua yam tsis tau khiav, thiab yooj yim rau style nrog. Txawm hais tias qee yam ntawm cov hmoov txheej tuaj yeem ua rau nyuaj, nws yeej tsis nyuaj, tshwj xeeb tshaj yog rau kev ua lag luam tus ntsuj plig. Kev tu kom zoo thiab cov cuab yeej tuaj yeem yog qhov sib txawv ntawm kev pib xyaum ua thiab kev ua haujlwm hmoov zoo.
Cov kauj ruam
Txoj Kev 1 ntawm 2: Ua Ntawv Thov Hmoov Txheej
Kauj Ruam 1. Txiav txim seb hom khoom siv twg koj yuav mus rau lub tsho loj thiab tom qab ntawd xaiv cov hmoov tsim nyog rau qhov ua tiav
Hmoov txheej yog ua tiav nrog cov thermoplastic lossis thermoset polymer hmoov, thiab cov ntaub ntawv no tau tsim los rau kev sib txuas nrog cov hlau sib txawv hauv paus kom muab cov txiaj ntsig zoo tshaj plaws.
Saib ntu tom ntej rau kev sib tham ntxaws ntxaws ntawm qhov sib txawv ntawm thermoset thiab thermoplastic tsho loj. Dab tsi yog qhov zoo rau lub tsheb yuav tsis zoo rau lub qhov me me los yog kho kom zoo nkauj
Kauj Ruam 2. Tshem tag nrho cov xov los yog lubricated cuam tshuam ua ntej koj pib, suav nrog txhua yam uas koj tsis xav tau txheej
Nws suab yooj yim, tab sis ntau tus neeg tsis nco qab cov kauj ruam no. Cov hmoov txheej uas koj thov yuav ua raws txhua yam (yog tias ua tau zoo) ntawm koj lub rig, ua qhov chaw sib khi, cov kabmob, clamps, ntsia liaj qhov rooj thiab txiv ntseej, thiab lwm yam tsis muaj txiaj ntsig tom qab tawg.
Kauj Ruam 3. Ntxuav lub hauv paus hlau kom huv si
Siv cov hlaws lossis cov nplaim tawg rau ntawm cov hlau tawv, xws li cov hlau cam khwb cia lossis hlau, yuav tshem cov zeb thiab xeb nplai, av thiab cov khoom siv txawv teb chaws. Kev ntxuav tshuaj hnyav yuav tshem tawm cov roj, roj, lossis pleev xim, thiab lub teeb xuab zeb tuaj yeem ua tiav los npaj qhov saum npoo. Aluminium, magnesium, thiab lwm yam hlau ua hlau tuaj yeem ua kom huv huv thiab xaim txhuam, lossis xuab zeb yog tias xav tau.
- Piv txwv li, koj yuav xuab zeb-tawg txhua yam koj xav tau rau hmoov txheej kom txog thaum nws poob qis rau cov hlau. Qhov no yog thawj kauj ruam hauv txheej txheem. Yog tias koj tsis muaj kev nkag mus rau lub tshuab xuab zeb, koj kuj tseem tuaj yeem siv lub log hlau, lub rooj zaum sib tsoo, lossis txawm tias cov ntawv xuab zeb. Tsuas yog ntev npaum li koj tau txais cov khoom mus rau liab qab hlau.
- Cov kauj ruam tom ntej yog hle cov hlau ntawm cov seem uas seem los yog hmoov av. Koj tuaj yeem ua tiav qhov no los ntawm kev so cov khoom hauv acetone (yog tias cov khoom me me txaus) lossis los ntawm kev so nws nrog cov ntaub so ntswg acetone-soaked.
Kauj Ruam 4. Siv cov hmoov txhuam rau cov khoom kom ua hmoov
Qhov no yog ua tiav siv "rab phom" lossis cov tshuab txau cua uas siv hluav taws xob tsub cov hmoov cov khoom kom nws lo rau cov khoom siv hlau hauv av uas tau txais txheej. Cov phom no muaj los ntawm ntau tus neeg xa khoom, thiab raug nqi tsawg li $ 100. Rau kev sim ua lub hom phiaj, koj tuaj yeem siv cov hmoov rau hauv cov hlau tiaj tus los ntawm hmoov av nws ncaj qha rau, thiab kis nws mus rau qhov nyias, txawm tias txheej.
- Nco ntsoov tias koj muaj koj cov nqi hluav taws xob sib txuas rau ib qho twg uas koj tau txheej. Cov hmoov uas koj siv yuav tsis ua raws cai tshwj tsis yog tias nws tau them nqi los tuav.
- Tom qab thov lub tsho tab sis ua ntej kho, ceev faj tsis txhuam los yog tshuab rau ntawm cov hmoov txheej, vim qhov no yuav ua rau qee cov hmoov poob, ua rau koj nrog lub tsho tsis meej.
Kauj Ruam 5. Kho cov hlau ntawm qhov kub kom haum rau cov khoom siv hmoov uas koj siv
Lub qhov cub zoo yog tsim rau lub hom phiaj no yog tias cov hlau me me txaus kom haum, txwv tsis pub, lub teeb hluav taws xob cua sov lossis lwm yam nplaim taws tsawg dua qhov cua sov yuav tsum tau siv. Feem ntau, cov khoom yog rhaub kom 350 ° txog 375 ° F (175 ° txog 190 ° C) li 10 txog 15 feeb, thiab tso cai kom txias.
Koj tuaj yeem siv lub qhov cub zoo ib yam los txhuam cov khoom me me. Tsuas yog nco ntsoov tias koj yuav tsis siv lub qhov cub los ua zaub mov tom qab cov hmoov txheej. Thaum koj tau siv lub qhov cub kom hmoov txheej, nws kiag li yuav tsum tsis txhob siv los ua noj.
Txoj Kev 2 ntawm 2: Thermosets v. Thermoplastics
Kauj Ruam 1. Siv cov thermoplastic txheej rau cov khoom uas koj tuaj yeem rov qab siv dua, thiab cov thermoset txheej rau cov khoom uas yuav nyob ruaj khov
Qhov sib txawv tseem ceeb ntawm thermoplastic thiab thermoset yog qhov thim rov qab ntawm lub tsho loj. Ib yam li lawv lub npe cuam tshuam, cov thermoset txheej tsis tuaj yeem rov yaj tom qab ua cov txheej txheem tshuaj lom neeg uas tsis hloov pauv. Hloov pauv, cov thermoplastic txheej tuaj yeem rov qab vim tias tsis muaj txheej txheem tshuaj lom neeg siv.
Cov ntsuas cua sov yog qhov zoo tshaj plaws rau cov khoom xws li khoom siv hluav taws xob thiab khoom siv vim tias lawv yuav tsum tau tiv tshav kub ntau dua, uas tuaj yeem ua rau cov thermoplastic txheej yuav yaj
Kauj Ruam 2. Xaiv cov thermotype raws li qee qhov tshwj xeeb ntawm lub tsho loj
Thermosets thiab thermoplastics muaj cov tshuaj sib txawv sib txawv, ua rau lawv zoo tagnrho rau kev siv sib txawv. Paub txog qee yam ntawm cov khoom no tuaj yeem pab koj xaiv hom twg los tsho nrog:
- Thermosets tau hais kom txhawb kev tsim kho kom ruaj khov ntawm ib yam khoom, ua rau lawv tshwj xeeb rau kev hnav hnyav thiab hnyav. Lawv kuj tseem muab cov khoom nrog tshuaj lom neeg thiab tiv taus cua sov, raws li tau hais los saum no.
- Thermoplastics muab kev sib xyaw ua kom muaj zog thiab yoog raws. Lawv feem ntau siv rau cov khoom xws li hnab yas thiab txawm tias cov khoom siv kho tshuab.
Kauj Ruam 3. Paub qhov zoo thiab qhov tsis zoo ntawm cov thermosets
Cov thermosets feem ntau siv los pleev cov khoom siv vim tias cov cua sov lawv tuaj yeem tiv taus.
- Qhov zoo: zoo nkauj zoo nkauj zoo nkauj; pheej yig; ntxiv dag zog thiab ruaj khov; tiv taus huab cua txias.
- Qhov tsis zoo: cov txheej txheem thim rov qab txhais tau tias thermoset tsis tuaj yeem siv tau; nyuaj dua kom tiav; hloov tsis tau.
Kauj Ruam 4. Paub qhov zoo thiab qhov tsis zoo ntawm cov yas yas
Thermoplastics tau siv rau ntau yam khoom, xws li lub rooj zaum hauv chaw ua si, uas xav tau ob qho tib si yas thiab ua haujlwm ntev.
- Qhov zoo: siab lubricity lossis tack; rov ua dua tshiab; muaj peev xwm rov tsim dua thiab/lossis rov tsim dua tshiab; ua rau muaj zog tiv taus.
- Qhov tsis zoo: kim dua (feem ntau); tuaj yeem yaj tawm yog tias kub tshaj.
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
Lub tswv yim
- Siv nyob rau qhov chaw muaj cua nkag tau zoo, huv si.
- Ntxuav thiab yaug tag nrho cov hlau saum npoo kom huv si, ib yam li txhua xim pleev xim.
- Hmoov txheej yog ib puag ncig tus phooj ywg, xeb thiab tiv taus UV lub teeb ua kom tiav. Txawm hais tias nws yog qhov ua tau zoo tshaj plaws nrog cov cuab yeej siv hauv kev tsim khoom, nws muaj peev xwm sim nrog nws hauv kev ua haujlwm hauv tsev.
- Ib txwm ua kom sov ib feem hauv qhov cub ua ntej txheej. Qhov no yuav tshem tawm cov roj lossis cov roj uas tseem nyob rau saum npoo. Yog tias ib feem tsis sov ua ntej, ib qho roj lossis roj tseem tshuav tom qab ntxuav tas yuav ua pa tawm thaum lub sij hawm kho thiab ua npuas kom tiav thaum kho.
- Muaj tus lej ntawm cov khoom siv rau hmoov sib tov hmoov, phom, thiab lwm yam khoom siv online.
- Nco ntsoov, koj yuav tsum tau ua kom sov cov khoom ua kom lo lo lo lo av, yog li koj yuav tsum muaj lub qhov cub uas yuav tuav tau daim, lossis txaus siab siv cov cua sov ncaj qha nrog lub teeb ci ci rau lub sijhawm txaus los kho nws.
- Sau tag nrho cov hmoov ntau dhau rau rov siv dua rau yav tom ntej.
Lus ceeb toom
- Tsis txhob ci hauv qhov cub roj.
- Kev ci cov txheej hauv lub qhov cub uas siv rau kev npaj zaub mov noj tsis pom zoo.
- Siv lub tshuab ua pa, hnab looj tes, thiab tiv thaiv qhov muag thaum txhuam cov hlau kom tshem cov nplai.
- Tsis txhob kov qhov khoom thaum nws raug tshem tawm ntawm qhov cub tom qab kho kom txog thaum nws txias tag.
- Tsis txhob noj! Tej zaum ua rau tuag taus.
- Tsis txhob nqus hmoov thaum ua ntawv thov.
