Isinqandi ukufudumeza: ncomo ixabiso

Njengoko kulwelo ukusebenza kwiinkqubo zokufudumeza ezisetyenziswa ngokubanzi ngenxa nokufumaneka kwayo kunye nendleko eziphantsi, kwakunye kwiipropati ezithile physicochemical, wafumana amanzi. Nangona kunjalo, ukusetyenziswa kwayo njengoko ulwelo ukusebenza kukho inani lokusilela langutana kulo mba kwiminyaka yakutshanje, uhlobo olutsha njengesipholisi, ebizwa ngokuba "zinendlela kwinkqubo ubushushu."

izinto eziluncedo zinendlela

• Into yokuqala ukuze anikele ingqalelo iingxaki ukuba ukususela ukusetyenziswa kwamanzi kwinkqubo zokufudumeza kuvuka. Ingqalelo igalelo elibi iphambili yale njengesipholisi ilixesha - ebusika xa akubandakanyi ixesha inkqubo ubushushu, qhwa amanzi kunokwenzeka kwaye ngenxa yoko, imijelo umsantsa elijonge imali. Le ngxaki ngokukodwa obukhulu kwindawo apho zokuhlala ezicetyiswayo ngamaxesha athile.
• Ukusetyenziswa kwamanzi kwinkqubo ubushushu njengoko kulwelo ukusebenza ekugqibeleni kukhokelela ukuyilwa kwemibhobho, le radiators kunye nobungakanani kwibhoyila, nto leyo kuguga iinkqubo zotshintshiselwano ubushushu, inkqubo nokusebenza apho kamva ukuze kungancitshiswa ngama- 30%.
• Ngokunciphisa ukusebenza eyandileyo amafutha, nto leyo eyandisa kakhulu ixabiso ubushushu.
• Le medium ndiwafudumeze ubilisa isisombululo isinqandi kubhetele kakhulu, ngenxa yokuba iziphene loo nto, eneneni kumafa yayo iqulethe ongeziweyo ezahlukileyo ukunciphisa ubushushu crystallization ukuya malunga 15-40 ° C.

Notes isicelo

Ezi izinto eniza kuyithengisa ukulungele ukusebenzisa ifomu okanye kanzulu. Isinqandi kwinkqubo ukufudumeza njenge mxube iqulethe kuphela ingxenye main - propylene ethers okanye ethylene ethers. Xa imozulu lethu ngokomlinganiselo umgangatho imixutywa ezizalayo ngu: sinezigaba ezibini ngu umthamo wamanzi amkelwe, inxalenye enye umthamo mxube.

• Ilungele ukusetyenziswa nonfreezing ulwelo iqulethe amanzi kunye 45% isisombululo kukho izinto kwesiseko wamandla. zinendlela enjalo kwinkqubo ukufudumeza ikhaya yenzelwe ukusetyenziswa kwiqondo lobushushu ukuya ku -30 ° C.
• Phambi epheleleyo zivula isinqandi mxube ke ekukhethwa ihlanjululwa ukuhlawula, yahluzwa okanye iziqholo amanzi.
• yoxinaniso Safe ethylene ethers emanzini ithathwa ngokuba ukuya ku-1 g / l. Ngokoxinzelelo akukho nako kakubi kokusingqongileyo.
• Kufuneka anikele ingqalelo ukuba umba zinendlela kwinkqubo ubushushu, xa kuthelekiswa amanzi inomlingani ophantsi komhlaba akhululeke. Oku kukhokelela ekubeni le isinqandi kulula ukungena kungena neentanda kunye pores, kwaye fluidity enkulu.
• Irabha phakathi ethylene ethers emthanda kancinci. Ngoko ke, kwimeko yokutshintshwa imibhobho yamanzi endala phezu evuzayo isinqandi zinokwenzeka.

Amagqabantshintshi nabenzi kunye nexabiso

Ngokomzekelo, khawucinge nje, ezinye antifreezes zale mihla ukuba iinkqubo zokufudumeza, ezo zisekelwe imichiza ezahlukeneyo.

• DIXIS -65.
• "Defriz".
• "Nangona Igazi Eco-65."
• "Stugna-H".

DIXIS -65

Le isinqandi kuba zivula sisisombululo esekelwe monoethylene ethers. Ukongeza, oko kuquka impahla ezininzi ongeziweyo, phakathi apho ekubalulekileyo ukuzikhankanya anti-umhlwa, ekwenzeni eliphezulu lobushushu kunye anti-amagwebu.

Kuba brand elinikiweyo crystallization uphawu ubushushu ilingana -68 ° C, evumela ukuba exutywe ngamanzi ethafeni.

Isinqandi le uphawu ikhutshwa kwiziphathi Iilitha ezingama-10 ukuya ku-50, njengoko ifumaneka ngokorhwebo ingafunyanwa kwi emilambo 200 litres. lentengo yale umxube ilitha-1 kuya kuba ukususela engange-70 ukuya kwi-90.

"Defriz"

Isiseko isinqandi "Defriz" kulele into bishofit. Kwakhona kumafa yayo Kwathi ongeziweyo ngokuthembekileyo sikhusela imibhobho esuka iidiphozithi isikali.

Lo mxube luqhutywa kwizikhongozeli Iilitha ezingama-10 no-50. Ixabiso anti-ngumkhenkce ukuya kwilitha 1 kwi-avareji engange 55-100.

"Nangona Igazi 65-Eco"

Le isinqandi yi ulwelo nonfreezing kwiinkqubo zokufudumeza, apho izizathu propylene ethers. Uyondelelwano lwee- propylene ethers - uhlobo of isiqinisekiso ukuba iqondo lobushushu crystallization ayidluli -65 ° C, kuvumela ukwenza ukuba yaze yangxenga ifuthe lomanyano ngamanzi plain kabini.

Kuyinto engangenwa kunye zinendlela non-yityhefu zivula. ixabiso layo ilitha 1 nganye iya kuba 75-90 engange. It yaqaphela tarakh 10, 20 okanye 50 eelitha, mhlawumbi kwi ekupakishweni kwisikhongozeli umthengi.

"Stugna-N"

Olu isinqandi khetho lusekelwe glycerin kwaye igqalwa indalo. Le qhwa lo mxube malunga -17 ° C.

Iphakheji ekhethekileyo additive sikhusela inkqubo zokufudumeza nxamnye ngokudleka netyuwa iidipozithi. Le imiphanda ilitha-50 okanye litre 10 zingathengwa kwinkqubo emelana ubushushu. ixabiso layo ilitha 1 nganye isusela ukusuka engange-70 ukuya 150.

iingcali Izimvo

Ngoko ke, isinqandi ngokuba ziingcali iinkqubo ukufudumeza unalo ukubuyekeza zilandelayo:

• Le njengesipholisi ugqibelele ukuba ngobomi akucingeleki, ngemihla kwilizwe lethu. Ukuba ndiwuzalise kwinkqubo zokufudumeza abantu xa ungekho wena, unokuqiniseka kokhuseleko yayo.
• Zuza qa ulwelo kufuneka ibe kuphela ezivenkileni ezizodwa, ukuthintela amathuba bathenge imveliso ophantsi-umgangatho okanye mbumbulu.
• Ukuze kuqinisekiswe ukuba zokufudumeza efanelekileyo kunye nokusetyenziswa kwale njengesipholisi, nje ukhethe iimpompo ezinamandla kunye radiators.
• Isinqandi ukhuselekile kwimpilo yoluntu kunye nobomi, inokusetyenziswa kuphela kumakhaya abucala, kodwa kumaziko zonyango kunye emfundo.
• Xa zisetyenziswa ngokuchanekileyo, olu hlobo njengesipholisi zinokuhlala kuwe iminyaka emihlanu ubuncinane.
• ulwelo isinqandi kuba zivula uluncedo kuphela kwiimeko apho ngokwenene kusenokwenzeka ukuba ngaphakathi inethiwekhi freeze amanzi.
