Thaum lub castor puas lawm, txoj kev ntsuam xyuas feem ntau yog los ntawm kev xyuas seb lub log puas tau puas lawm ntau npaum li cas. Txawm li cas los xij, muaj lwm qhov teeb meem tsis zoo sib txawv kiag li uas pom hauv daim teb: lub log tsheb nplaum, mos, thiab tawg me me, txawm tias tawg me me thaum khawb tes, txawm tias lub castor tsis tau siv ntev dhau los.
Qhov txawv txawv yog tias qee cov khoom siv, txawm tias siv tsis tshua muaj, kuj ntsib qhov teeb meem no.
Nyob rau lub sijhawm no, qhov ua rau yuav tsis yog qhov kev nkag siab ib txwm ntawm "hnav," tab sis yog qhov hydrolytic laus ntawm qee cov ntaub ntawv nto log nyob rau hauv cov xwm txheej tshwj xeeb.
1. "hydrolysis" ntawm cov ntaub ntawv castor wheel yog dab tsi?
Hauv qhov yooj yim, nws txhais tau tias tom qab raug dej noo ntev lossis ib puag ncig noo noo, cov qauv tshuaj ntawm qee cov ntaub ntawv polymer maj mam hloov pauv.
Qhov kev hloov pauv no txawv ntawm qhov chaw ntawm lub log uas raug "ua rau hauv av puas tsuaj".
Feem ntau qhov kev hnav tshwm sim hauv thaj chaw sib cuag ntawm lub log nto thiab hauv av, thaum hydrolysis cuam tshuam nrog kev hloov pauv maj mam hauv cov khoom siv, yog li nws tuaj yeem txuas ntxiv txhim kho txawm tias cov khoom siv tseem nyob ruaj khov rau lub sijhawm ntev.
Qhov no yog vim li cas qee cov khoom siv hauv Tshuag zoo li "yuav luag tsis siv," tsuas yog pom lawv cov log tsheb puas tsuaj ntau thaum rov qab tau ntau xyoo tom qab.
2. Puas yog txhua tus polyurethane casters ntshai hydrolysis?
Nws tsis tuaj yeem ua dav dav.
Polyurethane tsis yog ib yam khoom siv uas ruaj khov tag nrho tab sis yog ib yam khoom siv dav dav. Cov txheej txheem siv cov khoom siv raw, cov qauv, thiab cov txheej txheem tsim khoom sib txawv yuav muaj kev hloov pauv tseem ceeb hauv kev tiv thaiv hydrolysis.
Yog li ntawd, nws tsis yog qhov tseeb los xaus lus tias "cov log polyurethane tsis tuaj yeem siv rau hauv qhov chaw noo noo."
Cov kauj ruam tseem ceeb yog kom meej meej thaum lub sijhawm xaiv seb cov casters puas yuav nyob hauv kev sib cuag ntev nrog dej, qhov chaw noo noo siab, cov tshuaj ntxuav, lossis cov pa dej, thiab tom qab ntawd xaiv cov khoom siv tsim nyog dua raws li cov xwm txheej ua haujlwm tiag tiag.
Tsuas yog hais tias "Kuv xav tau lub log PU" rau tus neeg muag khoom tsis muab cov ntaub ntawv txaus.
3. Vim li cas qhov chaw kub thiab noo noo ntau dua thiaj li tseem ceeb dua?
Cov teeb meem hydrolysis muaj feem cuam tshuam nrog cov xwm txheej ib puag ncig.
Yog tias cov casters raug rau thaj chaw ntub dej ntev ntev thaum tib lub sijhawm ntsib qhov kub thiab txias siab dua, cov txheej txheem laus ntawm qee cov ntaub ntawv yuav dhau los ua qhov tseem ceeb dua.
Piv txwv li, cov chaw tsim khoom uas yuav tsum tau yaug ntau zaus, cov chaw khaws khoom ntub dej ntev, cov khoom siv ntxuav, qee qhov chaw ua zaub mov, thiab cov chaw ua haujlwm uas muaj dej noo, yuav tsum tau teev tseg ua ntej thaum lub sijhawm xaiv.
Qee zaum qhov muaj peev xwm thauj khoom ntawm cov casters tsis yog qhov teeb meem kiag li, thiab nws yog ib puag ncig uas txwv lawv cov xwm txheej siv.
4. Qhov txawv ntawm hydrolysis thiab kev hnav ib txwm yog dab tsi?
Kev hnav ib txwm feem ntau qhia txog cov yam ntxwv sib txawv.
Tom qab dov lub log nto mus rau hauv av ntev ntev, qhov chaw ua haujlwm maj mam nyias nyias, uas yog qhov tshwm sim yooj yim heev.
Thaum cov khoom siv qhia txog kev laus zuj zus, nws yuav tshwm sim ua qhov chaw ntawm lub log uas nplaum, poob qhov elasticity qub, qhov chaw tawg, hmoov av hauv zos, lossis thaiv kev tawg.
Yog tias cov casters tsis tau ua haujlwm hnyav tab sis pom muaj kev hloov pauv ntau yam ntawm cov khoom siv, qhov kev tshawb nrhiav yuav tsum tau nthuav dav los ntawm "hnav" mus rau qhov teeb meem sib xws ntawm cov ntaub ntawv thiab ib puag ncig.
5. Vim li cas cov khoom siv hauv Tshuag thiaj li muaj teeb meem?
Qhov tseeb tias cov casters tsis tau teeb tsa rau ntawm cov khoom siv tsis tau txhais hais tias cov khoom siv yuav tsis hloov pauv.
Qhov chaw cia khoom hauv lub tsev rau khoom kuj tseem ceeb ib yam.
Yog tias raug rau qhov kub thiab txias siab, av noo, tshav ntuj ncaj qha, lossis qhov chaw tsis haum rau kev khaws cia cov khoom siv ntev, qee cov ntaub ntawv polymer tseem yuav maj mam laus.
Yog li ntawd, rau cov khoom muag ntev ntawm cov casters, nws tsis pom zoo kom tsuas yog xyuas seb lub ntim khoom puas tiav.
Ua ntej muab nws rov qab siv dua, qhov chaw ntawm lub log tuaj yeem kuaj xyuas seb puas muaj qhov nplaum, tawg, tawv, mos, lossis qhov tsis zoo ntawm qhov chaw.
Tshwj xeeb tshaj yog rau cov khoom muag uas tsis tau muab faib rau lub sijhawm ntev, nws tsim nyog ua qhov kev tshuaj xyuas yooj yim.
6. Thaum xaiv cov khoom siv rau kev ntxuav ntau zaus, nug ib lo lus nug ntxiv
Cov neeg ua haujlwm yuav khoom feem ntau yuav qhia rau cov neeg muag khoom:
Lub cuab yeej siv sab hauv tsev
Tiam sis qhov xwm txheej ntawm 'sab hauv tsev' dav dhau lawm.
Ib lub tsev rau khoom ib txwm nyob hauv tsev, thiab qhov chaw ua zaub mov uas yuav tsum tau ntxuav txhua hnub kuj nyob hauv tsev. Cov kev xav tau rau cov ntaub ntawv caster hauv ob qho chaw ib puag ncig yuav txawv kiag li.
Yog li ntawd, yog tias cov khoom siv yuav tsum tau ntxuav tas li, yuav tsum piav qhia ntxiv txog qhov zaus ntxuav, seb puas muaj dej sib sau ua ke ntev, seb puas siv cov tshuaj ntxuav, thiab seb lub log puas nyob hauv qhov ntub dej ntev.
Cov ntaub ntawv no feem ntau muaj nqis ntau dua li tsuas yog qhia cov neeg muag khoom siv sab hauv tsev xwb.
7. Pom qhov chaw ntawm lub log tsis zoo, tsis txhob maj hloov nrog tib lub qauv xwb
Yog tias ib pawg ntawm cov log qhia txog kev sib txuas zoo sib xws, tawg, lossis poob, qhov kev daws teeb meem yooj yim yog hloov lawv nrog cov tshiab.
Tab sis yog tias cov neeg ua haujlwm tshiab tseem siv cov khoom siv tib yam thiab qhov chaw nyob hauv tsev tseem tsis tau hloov pauv, cov teeb meem zoo sib xws yuav tshwm sim dua.
Ib txoj hauv kev tsim nyog dua yog ua ntej kom paub meej tias:
Lub cuab yeej no nyob ntev npaum li cas hauv qhov chaw noo noo?
Koj puas nquag kov dej?
Puas muaj ib txoj kev ntxuav?
Puas muaj cov pa dej nyob ntev ze ntawm lub log?
Cov xwm txheej khaws cia hauv lub tsev rau khoom puas tsim nyog?
Tom qab lees paub cov yam no, soj ntsuam seb cov khoom siv ntawm lub log puas yuav tsum tau hloov kho.
Sau rau thaum kawg
Qhov ua tsis tiav ntawm cov casters tsis yog ib txwm vim siv ntau dhau.
Muaj tej lub log khiav ceev heev txhua hnub, tiam sis qhov chaw ntawm lub log tseem ruaj khov; Tej lub log tej zaum yuav tsis siv ntau zaus, tiam sis tej zaum yuav laus ua ntej lub sijhawm vim yog ib puag ncig thiab cov khoom siv tsis sib xws.
Qhov no kuj yog ib qho taw tes uas feem ntau tsis quav ntsej thaum xaiv cov neeg ua haujlwm:
Ntxiv rau qhov nug tias lub cuab yeej hnyav npaum li cas thiab nws khiav hauv av li cas, koj yuav tsum nug seb qhov chaw uas cov neeg ua haujlwm sib cuag nrog txhua hnub yog dab tsi.
Thaum lub log pib lo, tawg lossis poob, nws zoo dua tsis txhob hais tias nws yog vim "cov khoom siv tsis zoo". Kev tshuaj xyuas ntxiv ntawm kev siv thiab qhov chaw cia khoom feem ntau ua rau nws yooj yim dua los nrhiav qhov ua rau tiag tiag.
