Peb tab tom sim nthuav tawm qhov tsis pub leejtwg paub ntawm cov khoom xyaw ntawm WD-40
Chaw Tsim Tshuaj
WD-40 tau tsim los ntawm American chemist Norman Larsen. Nyob rau hauv nruab nrab ntawm lub xyoo pua XNUMXth, tus kws tshawb fawb tau ua haujlwm ntawm Rocket Chemical Company thiab sim tsim cov khoom uas tuaj yeem ua tiav cov dej noo hauv Atlas foob pob hluav taws. Cov dej noo condensing ntawm cov hlau yog ib qho teeb meem nrog cov foob pob hluav taws. Nws yog ib qhov chaw ntawm corrosion ntawm daim tawv nqaij, uas cuam tshuam qhov txo ntawm lub sij hawm txuag ntawm cia. Thiab xyoo 1953, los ntawm kev siv zog ntawm Norman Larsen, WD-40 kua tau tshwm sim.
Rau lub hom phiaj ntawm kev tshawb fawb foob pob hluav taws, raws li kev sim tau pom, nws tsis ua haujlwm zoo heev. Txawm hais tias nws tseem siv tau rau qee lub sijhawm los ua qhov tseem ceeb corrosion inhibitor rau missile tawv.
Larsen sim hloov nws qhov kev tsim tawm los ntawm lub foob pob hluav taws, kev lag luam tshwj xeeb, mus rau tsev neeg thiab kev siv dav dav. Tsis ntev nws tau pom tseeb tias cov muaj pes tsawg leeg ntawm VD-40 muaj cov khoom muaj txiaj ntsig zoo hauv lub neej txhua hnub. Cov kua muaj peev xwm nkag tau zoo heev, sai sai liquefies txheej txheej ntawm corrosion, lubricates zoo thiab tiv thaiv kev tsim ntawm Frost.
Ntawm cov rhawv ntawm San Diego cov khw muag khoom, qhov chaw Norman Larsen lub chaw kuaj mob, cov kua tau tshwm sim thawj zaug hauv xyoo 1958. Thiab nyob rau hauv 1969, tam sim no tus thawj tswj hwm ntawm lub tuam txhab tau hloov lub npe ntawm lub Rocket Chemical tuam txhab, uas nws lub taub hau, mus rau lub ntsiab lus thiab tseeb: "WD-40".
Kev sib xyaw ntawm WD-40 kua
Lub invention ntawm Norman Larsen, qhov tseeb, tsis yog ib yam dab tsi tawg nyob rau hauv lub teb ntawm chemistry. Tus kws tshawb fawb tsis tuaj nrog cov ntaub ntawv tshiab lossis hloov pauv. Nws tsuas muaj peev xwm mus txog qhov txheej txheem rau kev xaiv thiab sib tov cov khoom uas twb paub lawm thaum lub sijhawm ntawd hauv qhov kev faib ua feem uas zoo rau cov haujlwm uas tau muab rau cov khoom tsim.
Cov muaj pes tsawg leeg ntawm WD-40 yog yuav luag tag nrho nthuav tawm nyob rau hauv cov ntaub ntawv kev nyab xeeb, vim qhov no yog ib tug yuav tsum tau cov ntaub ntawv nyob rau hauv lub tebchaws United States, qhov twg cov kua tau tsim. Txawm li cas los xij, qhov tseem ceeb ntawm WD-40 tseem yog kev lag luam zais cia.
Niaj hnub no nws tau paub tias lub lubricating-xws li muaj pes tsawg leeg VD-40 suav nrog cov hauv qab no:
- dab dawb (los yog nefras) - yog lub hauv paus ntawm WD-40 thiab ua kom txog li ib nrab ntawm tag nrho cov ntim;
- carbon dioxide yog tus qauv propellant rau aerosol formulations, nws feem yog hais txog 25% ntawm tag nrho cov ntim;
- Cov roj ntxhia nruab nrab - ua kom txog li 15% ntawm qhov ntim ntawm cov kua thiab ua cov roj nplua nyeem thiab cov khoom thauj rau lwm cov khoom;
- Cov khoom xyaw inert - cov khoom tsis pub lwm tus paub uas muab cov kua dej hais tawm nkag mus, tiv thaiv thiab lubricating zog.
Qee cov tuam ntxhab tau sim thiab sim khaws cov "cov khoom xyaw zais cia" hauv qhov sib npaug. Txawm li cas los xij, txog niaj hnub no, tsis muaj leej twg tuaj yeem ua raws nraim li cov khoom tsim los ntawm Larsen.
Analogs
Tsis muaj analogues rau WD-40 kua. Muaj cov khoom sib xyaw uas zoo sib xws hauv kev muaj pes tsawg leeg thiab kev ua haujlwm zoo. Cia peb luv luv xav txog qhov zoo sib xws ntawm VD-40 nyob rau hauv Lavxias teb sab Federation.
- AGAT SilverLine Master Key. Ib qho ntawm cov dej nkag tau zoo tshaj plaws ntawm kev ua lag luam. Tus nqi ntawm aerosol tuaj yeem nrog ntim ntawm 520 ml yog hais txog 250 rubles. Tshaj tawm nws tus kheej ua ib qho analogue ntawm VD-40. Nyob rau hauv qhov tseeb, qhov no yog ib tug muaj pes tsawg leeg zoo sib xws nyob rau hauv kev txiav txim, tab sis tsis yog tag nrho cov analogue. Kev ua tau zoo, raws li cov neeg tsav tsheb, yog me ntsis qis dua qhov qub. Nyob rau sab plus, nws tsw zoo.
- Kua yuam sij los ntawm ASTROhim. Rau 335 ml aerosol tuaj yeem, koj yuav tau them txog 130 rubles. Kev txiav txim los ntawm kev tshuaj xyuas ntawm cov neeg tsav tsheb, tsis yog qhov kev kho zoo tshaj plaws. Nws muaj ib tug pronounced tsw ntawm diesel roj. Nws muaj zog nkag tau zoo. Haum rau kev yooj yim ua hauj lwm nrog rusted threads los yog pob qij txha ntawm hlau qhov chaw. Nyob rau hauv cov nqe lus ntawm lubrication los yog corrosion tiv thaiv, nws yog inferior rau WD-40 kua.
- Kev nkag mus rau roj nplua nyeem DG-40 los ntawm 3Ton. Tej zaum qhov kev xaiv pheej yig tshaj. Rau ib lub raj mis nrog ib tug sprayer nrog ib tug ntim ntawm 335 rubles, koj yuav tau them txog 100 rubles. Nyob rau tib lub sijhawm, kev ua haujlwm ua haujlwm tau zoo sib xws. Haum tsuas yog rau kev yooj yim ua hauj lwm nrog me ntsis corrosion nyob rau hauv lub interfaces ntawm qhov chaw thiab threads. Lub lubricant ua haujlwm tsis zoo li cas. Muaj ib qho tsis kaj siab tsw.
- Kua Key AutoProfi. Pheej yig thiab haum zoo lubricant. Copes nrog nws cov dej num tsis zoo dua li qub VD-40. Nyob rau tib lub sijhawm, qhov nruab nrab ntawm 400 rubles raug nug rau ntawm kev ua lag luam rau 160 ml lub raj mis, uas, ntawm qhov ntim, yuav luag peb zaug pheej yig dua VDshka.
- Ua kua ntswj Sintec. Ib lub raj mis aerosol nrog ntim ntawm 210 ml ntawm Sintec kua tseem ceeb raug nqi ib ncig ntawm 120 rubles. Cov tshuaj tsw qab zoo li kerosene. Ua haujlwm tsis zoo. Haum rau tu oily deposits los yog soot. Lubricity thiab nkag mus yog feem ntau tsis muaj zog.
Tsis muaj chaw tsim khoom muaj peev xwm ua tiav 100% kev sib tw nrog tus thawj VD-40.
DIY WD-40
Muaj ntau cov zaub mov txawv rau kev npaj cov kua nrog cov khoom zoo ib yam li WD-40 hauv tsev. Cia peb xav txog hauv kev nthuav dav tsuas yog ib daim ntawv qhia, uas, nyob rau hauv kev xav ntawm tus sau, yuav muab cov zis muaj pes tsawg leeg zoo ib yam li cov thawj, thiab nyob rau tib lub sij hawm yuav muaj nyob rau hauv nws tus kheej ntau lawm ntawm pawg.
Daim ntawv qhia yog yooj yim.
- 10% ntawm cov roj nruab nrab viscosity. Cov dej ntxhia yooj yim tshaj plaws nrog cov viscosity ntawm 10W-40 lossis cov roj ntws tawm tsis muaj lub nra nrog cov khoom ntxiv yog qhov zoo tshaj plaws.
- 40% qis-octane roj av "Kalosha".
- 50% dab dawb.
Tsuas yog sib tov cov khoom hauv txhua qhov kev txiav txim. Tsis muaj kev sib nrig sib tshua yuav tshwm sim thaum ua noj. Cov zis yuav yog ib tug haum zoo lubricating muaj pes tsawg leeg nrog ib tug zoo penetrating nyhuv. Qhov tsuas yog qhov tsis zoo yog qhov xav tau rau daim ntawv thov kev sib cuag ntawm qhov yuav tsum tau ua. Txawm hais tias qhov teeb meem no tau yooj yim daws tau los ntawm kev yuav lub raj mis nrog cov tshuaj tsuag tshuab.
Kev sib txawv ntawm cov parodies ntawm WD-40 siv roj diesel, roj av, roj av thiab cov kuab tshuaj hauv tsev tau paub. Ntxiv mus, cov proportions thiab cov muaj pes tsawg leeg tsis raug tswj los ntawm lwm yam tshaj li qhov xav tau ntawm cov chaw tsim khoom. Thiab cov kua dej uas tau tshwm sim hauv qhov no yuav muaj cov yam ntxwv tsis tuaj yeem, feem ntau nrog lub ntsej muag ntse ntawm ib qho khoom.
