Dej ntsuab liab thiab nws lwm views

Dej ntsuab yog ib tug ua kua uas nws khov kub ntau npaum li cas qis tshaj cov crystallization kub ntawm cov dej. Siv cov kua yuav pab tiv thaiv kom txhob puas tsuaj rau lub mechanisms uas yuav tshwm sim thaum H2O crystallization. Dej ntsuab (liab, daj, ntsuab, thiab lwm yam) muaj dej thiab ib tug polyhydric haus dej cawv. Nyob rau hauv tas li ntawd, lub coolant yog ntxiv ntau yam additives, corrosion resistant Cheebtsam zoo li. Cov kev sib txuas rau kom cov kev tiv thaiv kev nthuav dav. Raws li ib feem ntawm cov kua kuj muaj dyes, uas muab lawv ib tug xim. Raws li cov lus ntawm cov kws txawj, cov kua xim muaj tsis ntxim rau nws cov kev ua tau zoo. Nyob rau hauv raws li ib tug tau, dej ntsuab (liab thiab nws lwm hom) tej zaum yuav comprise ethylene glycol los yog propylene glycol.

Cov yav tas yog ib tug tsis muaj kob khov oily kua. Nws muaj ib tug yam ntxwv yoob tsis nco qab tsw. Ethylene glycol yog ib tug muaj zog tshuaj lom, li ntawd, ceev faj thaum kov lawv. Ntshiab ethylene glycol khov ntawm Rho tawm tsug kaum peb degrees. nws kub taw tes yog 197 degrees. Nws yuav tsum tau hais tias tus ethylene glycol nyob rau hauv lub concentrated aqueous tov freezes ntawm ib tug tsawg kub (yog tias siv ob qhov chaw ntawm ethylene glycol thiab ib feem dej). Boiling point dej ntsuab nyob rau nruab nrab yog hais txog ib puas nees nkaum degrees, thiab qhov tsawg kawg nkaus ntawm nws cov khov taw tes tej zaum yuav xya caum degrees hauv qab no zero. Raws li ib tug txoj cai, dej ntsuab (liab, daj, thiab lwm yam) muaj nyob rau hauv nws cov muaj pes tsawg leeg txog 50-60% ethylene glycol. Nyob rau hauv cov ntaub ntawv no, nws yog sib npaug zos rau qhov tsawg kawg nkaus khov kub ntawm peb caug degrees hauv qab no zero.

Nyob rau hauv lub chaw ua khoom ntawm dej ntsuab nws tseem yog feem ntau heev siv propylene glycol. Qhov no cov ntaub ntawv uas yog ntau environmentally phooj ywg. Nyob rau hauv cov ntaub ntawv no, qhov kev kawm yog yuav luag ywj siab ntawm lub hauv paus. Txawm li cas los, propylene glycol yog kev ruaj ntseg thiab tsawg lom.

Lo lus "anti-freeze" yuav cia txhais li "anti-te" los yog "cov dej khov-free". Qhov no lub sij hawm yog siv los xa mus rau tag nrho cov hom ntawm coolants.

Dej ntsuab los yog dej ntsuab - uas yog ib qho zoo?

Nws yuav tsum tau muab sau tseg ntawm tus nyuam uas tus thawj tswvyim yog siv los xa mus rau kua domestic ntau lawm. Lub sij hawm "dej ntsuab" muaj lub npe ntawm daim card, nyob rau hauv uas nws tau tsim (Organic Synthesis yees Division (CBT)). Xaus "ol" yog hais txog ib tug cov ntaub ntawv uas teej tug mus rau lub haus dej cawv. Dej ntsuab yog hais txog cov tshuaj coolants uas nyuam qhuav ntau thiab ntau tsis tshua muaj siv.

Raws li twb tau sau tseg, qhov kev kawm thaj chaw ntawm cov ntaub ntawv uas tsis yog nyob ntawm seb seb qhov no yog qhov dej ntsuab - liab, xiav, daj, los yog ntau tshaj ntawm cov xim. Chiv, tag nrho cov kua ua los ntawm cov xim tib yam. Dej ntsuab xim ntxiv ib yam "cwm pwm." Nws yog ntseeg hais tias tso cai rau nws kua ntawm tib xim rau txhua lwm yam. Nws yuav tsum tau muab sau tseg tias nws yog yuam kev nyob rau hauv ntau lub respects. Lub ntim ntawm dej ntsuab chaw tsim tshuaj paus yeej ib txwm muab cov lus qhia mus rau lub nws muaj peev xwm ntawm nws hom nrog lwm leej lwm tus.

Nyob rau tib lub sij hawm ib tug tej yam lub xeev tus qauv tau tsim rau domestic cev. Nws yuav tsum tau, txawm li cas los, yuav muab sau tseg tias tsis conformity ntawm GOST tsis tau lees tias lawv cov qib high quality yam ntxwv. Piv txwv li, dej ntsuab Lavxias teb sab ntau lawm tsis yeej ib txwm siv rau niaj hnub designs xyaw. Nyob rau hauv cov ntaub ntawv no, cov nyob sab Europe anti-freeze yog tsis tseem ceeb rau lub Lavxias teb sab txheem, qhia siab zoo ua tau zoo.
