Sizama ukwembula imfihlo yokwakheka kwe-WD-40
Umkhiqizi
I-WD-40 yasungulwa ngusokhemisi waseMelika uNorman Larsen. Maphakathi nekhulu lama-XNUMX, usosayensi wasebenza e-Rocket Chemical Company futhi wazama ukudala into engakwazi ukulwa ngokuphumelelayo nomswakama kumarokhethi e-Atlas. Ukujiya komswakama endaweni yensimbi kwakungenye yezinkinga kulawa marokhethi. Kwakuwumthombo wokugqwala kwesikhumba, okwathinta ukuncishiswa kwesikhathi sokulondoloza isitoreji. Futhi ngo-1953, ngemizamo kaNorman Larsen, kwavela uketshezi lwe-WD-40.
Ngezinhloso zesayensi ye-rocket, njengoba ucwaningo luye lwabonisa, ayizange isebenze kahle kakhulu. Nakuba yayisasetshenziswa isikhathi esithile njenge-corrosion inhibitor eyinhloko yezikhumba ze-missile.
ULarsen wazama ukudlulisa okusunguliwe kwakhe kusuka ku-rocket, imboni ekhethekile kakhulu, ukuya endlini kanye nobuchwepheshe obujwayelekile. Ngokushesha kwaba sobala ukuthi ukwakheka VD-40 has a eziyinkimbinkimbi izakhiwo ewusizo ekuphileni kwansuku zonke. Uketshezi lunekhono elihle kakhulu lokungena, lubilisa ngokushesha izingqimba ezingaphezulu zokugqwala, lugcobe kahle futhi luvimbele ukwakheka kwesithwathwa.
Emashalofini ezitolo zaseSan Diego, lapho kwakukhona ilabhorethri kaNorman Larsen, uketshezi lwaqala ukuvela ngo-1958. Futhi ngo-1969, umongameli wamanje wenkampani washintsha igama Rocket Chemical Company, okuyinto inhloko, ukuze emfushane kakhudlwana futhi iqiniso: WD-40.
Ukwakhiwa kwe-WD-40 liquid
Ukusungulwa kukaNorman Larsen, empeleni, akuyona into eyimpumelelo emkhakheni wamakhemikhali. Usosayensi akazange aqhamuke nezinto ezintsha noma eziguqulayo. Wasondela kuphela ngendlela efanele enqubweni yokukhetha nokuxuba izinto ezavele zaziwa ngaleso sikhathi ngengxenye eyayifanele imisebenzi eyabelwe into edaliwe.
Ukwakheka kwe-WD-40 kucishe kudalulwe ngokuphelele ephepheni ledatha yokuphepha, ngoba lokhu kuyidokhumenti eyisibopho e-USA, lapho uketshezi lwakhiwe khona. Kodwa-ke, okugqamile kwe-WD-40 kuseyimfihlo yohwebo.
Namuhla kuyaziwa ukuthi ukwakheka kwe-lubricating-penetrating VD-40 kuhlanganisa lezi zingxenye ezilandelayo:
- umoya omhlophe (noma i-nefras) - isisekelo se-WD-40 futhi yenza cishe ingxenye yevolumu ephelele;
- i-carbon dioxide iyi-propellant evamile yokwakhiwa kwe-aerosol, isabelo sayo simayelana nama-25% wevolumu ephelele;
- uwoyela wamaminerali angathathi hlangothi - wenza cishe u-15% wevolumu yoketshezi futhi usebenza njenge-lubricant kanye nomthwali wezinye izingxenye;
- izithako ze-inert - izakhi eziyimfihlo kakhulu ezinikeza uketshezi ukuphinyiselwa kwezakhiwo zokungena, zokuzivikela nezokugcoba.
Abanye abakhiqizi bazame futhi bazama ukucosha lezi "zithako eziyimfihlo" ngezilinganiso ezifanele. Nokho, kuze kube manje, akekho oye wakwazi ukuphinda ncamashi ukwakheka eyasungulwa Larsen.
Ama-Analog
Awekho ama-analogue we-WD-40 liquid. Kukhona izingxube ezifanayo kakhulu ekubunjweni nasekusebenzeni izici. Ake sicabangele kafushane ukufana edume kakhulu VD-40 in the Russian Federation.
- I-AGAT SilverLine Master Key. Olunye uketshezi olungena ngempumelelo emakethe. Intengo ye-aerosol ithini enomthamo wama-520 ml imayelana nama-ruble angama-250. Izimemezela njenge-analogue ye-VD-40. Eqinisweni, lokhu ukwakheka okufanayo ngesenzo, kodwa hhayi i-analogue ephelele. Ukusebenza kahle, ngokusho kwabashayeli, kuthi kancane kuphansi kuneyasekuqaleni. Ngakolunye uhlangothi, iphunga elimnandi.
- Ukhiye woketshezi oluvela ku-ASTROhim. Ukuze uthole i-aerosol engu-335 ml, kuzodingeka ukhokhe cishe ama-ruble angu-130. Uma sibheka ukubuyekezwa kwabashayeli, hhayi ikhambi eliphumelela kakhulu. Inephunga elizwakalayo likadizili. Inamandla amahle okungena. Ifanele ukwenza lula umsebenzi ngemicu egqwalile noma amalunga ezingxenye zensimbi. Mayelana nokuthambisa noma ukuvikela ukugqwala, ingaphansi koketshezi lwe-WD-40.
- I-lubricant engena i-DG-40 isuka ku-3Ton. Mhlawumbe inketho eshibhe kakhulu. Ukuze ibhodlela nge sprayer umthamo ruble 335, kuzodingeka ukhokhe ruble mayelana 100. Ngesikhathi esifanayo, ukusebenza kahle komsebenzi kuhambisana. Ifanele kuphela ukwenza lula umsebenzi ngokugqwala okuncane ezindaweni zokuhlangana zezingxenye nemicu. I-lubricant isebenza kanjani kabi. Inephunga elingemnandi.
- I-Liquid Key AutoProfi. I-lubricant engabizi futhi esebenza kahle. Ibhekana nemisebenzi yayo hhayi kubi kakhulu kune-VD-40 yasekuqaleni. Ngesikhathi esifanayo, isilinganiso sama-ruble angu-400 sicelwa emakethe ibhodlela le-160 ml, okuyinto, ngokwevolumu, cishe izikhathi ezintathu ezishibhile kune-VDshka.
- Isikrufu samanzi Sintec. Ibhodlela le-aerosol elinevolumu engu-210 ml yokhiye we-Sintec liquid libiza cishe ama-ruble angu-120. Ukwakheka kunuka uphalafini. Isebenza kabi. Ifanele ukuhlanza amadiphozithi anamafutha noma umule. Ukuthambisa kanye nokungena ngokuvamile akunamandla.
Akekho umkhiqizi okwazile ukuzuza ukufana okungu-100% ne-VD-40 yoqobo.
I-DIY WD-40
Kunezindlela zokupheka eziningi zokulungiselela uketshezi olunezakhiwo ezifana ne-WD-40 ekhaya. Ake sicabangele ngokuningiliziwe iresiphi eyodwa kuphela, okuzothi, ngokombono womlobi, izonikeza ukwakheka kokukhishwayo okufana kakhulu nokwasekuqaleni, futhi ngesikhathi esifanayo kuzotholakala ekuzikhiqizeni kwakho phakathi kwabantu abaningi.
Iresiphi ilula.
- I-10% yanoma yimuphi uwoyela we-viscosity ophakathi. Amanzi amaminerali alula ane-viscosity ye-10W-40 noma amafutha ashisayo angathwele izithasiselo afaneleka kakhulu.
- 40% low-octane uphethiloli "Kalosha".
- 50% umoya omhlophe.
Vele uhlanganise izingxenye nganoma iyiphi indlela. Akukho ukusabela kwamakhemikhali okuhambisanayo okuzokwenzeka ngesikhathi sokupheka. Okukhiphayo kuzoba ukwakheka kokuthambisa okusebenzayo okunomphumela omuhle wokungena. Okuwukuphela kwe-drawback yisidingo sohlelo lokusebenza lokuxhumana endaweni edingekayo. Nakuba le nkinga ixazululwa kalula ngokuthenga ibhodlela nge-spray mechanical.
Izinhlobonhlobo zama-parodies we-WD-40 zaziwa kusetshenziswa uphethiloli we-diesel, uphethiloli, uphalafini kanye ne-solvent evamile yasendlini. Ngaphezu kwalokho, izilinganiso kanye nokwakheka okuqondile akulawulwa yinoma yini enye ngaphandle kwesifiso somkhiqizi. Futhi uketshezi oluba khona kulesi simo luzoba nezici ezingalindelekile, ngokuvamile ngokubhekela okubukhali kunoma iyiphi impahla eyodwa.
