Abstract
Description
Išradimas priklauso hermetinimo skysčių gamybos pramonei ir pateikia hermetinimo skysčio gamybos būdą, pagal kurį pagamintas hermetinimo skystis naudojamas apsaugoti deaeruotąjį vandenį ir hidrofilinius skysčius nuo išgaravimo, prisotinimo dujomis, mechaniniais teršalais iš atmosferos bei apsaugoti rezervuaro įrengimus nuo korozijos.BACKGROUND OF THE INVENTION The present invention relates to a process for the manufacture of a sealing fluid, and to a method for producing a sealing fluid, wherein the sealing fluid produced is used to protect deaerated water and hydrophilic liquids from evaporation, gas saturation, mechanical pollutants from the atmosphere
Laikant deaeruotąjį vandenį bakuose-akumuliatoriuose jis iš oro prisotinamas deguonimi. Aukšta vandens temperatūra (95-98°C) ir netgi nedidelis jame esančio oro kiekis sukelia intensyvų korozinį metalinių vamzdynų bei kitų termofikacijos sistemos įrengimų irimą.When storing deaerated water in tanks, it is oxygenated from the air. High water temperature (95-98 ° C) and even a small amount of air in it cause intense corrosion of metal pipelines and other equipment of the cogeneration system.
Tuo pačiu korozijos produktai pablogina vandens kokybę.At the same time, corrosion products impair water quality.
Plaukioj antys mediniai pontonai ir polimeriniai tuščiaviduriai rutuliukai nebuvo pritaikyti praktiškai, nes jie patikimai neužtikrindavo hermetiškumo, o taip pat ir vandens paviršiaus izoliavimo nuo atmosferos.Floating wooden pontoons and polymeric hollow beads were not used in practice because they did not reliably ensure airtightness, as well as insulating the water surface from the atmosphere.
Siekiant pašalinti šiuos trūkumus buvo sukurtas hermetinimo skystis, kurio klampiai elastinga savitekė struktūra ant laisvo vandens paviršiaus bakuoseakumuliatoriuose ilgam laikui užtikrina praktinį vandens hermetinimą ir tuo pačiu padeda išlaikyti jo kokybę bei temperatūrą.To remedy these drawbacks, a sealing fluid has been developed whose viscous elastic self-draining structure on a free water surface in a batch accumulator provides long-term practical water sealing while maintaining its quality and temperature.
Žinomi hermetinimo skysčio gamybos būdai tirpinant poliizobutileną mineralinėje alyvoje ir palaipsniui pridedant tikslinius komponentus, kurie būtini norint gauti numatytas hermetinimo skysčio charakteristikas, gerinančias elastingumą, nelaidumą dujoms, tarnavimo laiką, šiluminį stabilumą ir t.t., ir vėliau išmaišant visą masę iki visiško jos paruošimo. (SU išradimas Nr. 223976, C 09 K 3/10, 1967).Known methods of making the sealing fluid are by dissolving polyisobutylene in mineral oil and gradually adding the target components necessary to obtain the intended sealing fluid characteristics that improve elasticity, impermeability to gas, service life, thermal stability, etc., and subsequently mix the entire mass until complete preparation. (SU Invention No. 223976, C 09 K 3/10, 1967).
Aprašytasis būdas neleidžia detaliai įsivaizduoti hermetinimo skysčio gamybos, nes šis procesas aprašytas trumpai, reikalauja didelių sąnaudų, nes maišomi brangūs komponentai, o taip pat ilgai užtrunka, nes stengiamasi gauti universalų hermetinimo skystį.The method described does not allow for a detailed view of the production of the sealing fluid as this process is brief, high-cost, expensive components are mixed, and also takes a long time to obtain a universal sealing fluid.
Pasiūlytasis hermetinimo skysčio gamybos būdas šių trūkumų neturi.The proposed method of producing the sealing fluid does not have these disadvantages.
Išradimo esmė yra ta, kad hermetinimo skysčio gamyba vyksta keliais etapais; pirmajame etape susmulkinamas poliizobutilenas ir užpilamas mineraline alyva, dedant jo 20-35% į visą alyvos kiekį, ir ši masė maišoma 50-70% laiko, kuris reikalingas visai skysčio gamybai; antrajame arba paskutiniame etape į gautąją masę dedami tiksliniai komponentai ir maišoma 8,3-15% laiko, kuris reikalingas visai skysčio gamybai, o kituose etapuose supilama 65-80% mineralinės alyvos pradžioje vienodais kiekiais, vėliau didėjančiais bent du kartus per vienodus arba dviejų kartotinius laiko intervalus, be to, visos maišymo operacijos atliekamos 95-110°C temperatūroje.The essence of the invention is that the production of the sealing fluid takes place in several stages; in the first step, the polyisobutylene is crushed and filled with mineral oil, 20-35% of which is added to the total amount of oil, and the mass is stirred for 50-70% of the time required to produce all the liquid; in the second or final step, the target components are added to the resulting mass and mixed in 8.3-15% of the time required to produce all the liquid, and in the next steps 65-80% of the mineral oil is added initially in equal quantities, subsequently increasing at least twice in equal or and all mixing operations are performed at 95-110 ° C.
Hermetinimo skystis gaminamas mažiausiai keturiais etapais, be to, trečiajame ir ketvirtajame etape pilamos mineralinės alyvos masės santykis lygus bent jau 1:2, o tiksliniai komponentai, kurie dedami antrajame arba ketvirtajame etape, prieš tai maišomi 10-15% laiko reikalingo viso hermetinimo skysčio gaminimo alyvoje, kurios kiekis sudaro 10-15% visojo kiekio.The sealing fluid is produced in at least four steps, and in the third and fourth stages, the weight ratio of mineral oil to be poured is at least 1: 2, and the target components added in the second or fourth step are premixed for 10-15% of the time required to produce the sealant. in oil containing 10-15% of the total.
Žemiau pateiktose lentelėse yra pasiūlytojo hermetinimo skysčio gamybos būdo pavyzdžiai, kai tiksliniai komponentai į maišytuvą dedami atitinkamai antrajame ir paskutiniame etapuose, o vėliau pridedama pramoninės alyvos.The following tables give examples of the proposed method of manufacturing the sealing fluid, whereby the target components are added to the mixer in the second and final stages respectively, followed by the addition of industrial oils.

Technological mode norms for the JI3JI - 630 - 01 mixer to produce 630 sealing fluid when the target components are added to the mixer in the final step
Siekiant sutrumpinti hermetinimo skysčio gamybos laiką galima iš anksto sumaišyti tikslinius komponentus su mineraline alyva.Pre-mixing of the target components with mineral oil can be done to shorten the sealing fluid production time.
Maišymas trunka 10-15% laiko, reikalingo visai skysčio gamybai alyvoje, kurios kiekis sudaro 10-15% viso kiekio, o Ši masė vėliau sudedama antrajame arba paskutiniame etape.The mixing takes 10-15% of the time needed to produce all the liquid in the oil, which is 10-15% of the total amount, which is then added in the second or final step.
Pasiūlytasis būdas leidžia gauti hermetinimo skystį, priklausomai nuo jo paskirties, pridedant tik tikslinių komponentų, o ne universalų hermetinimo skystį, ir sutrumpinti jo gamybos laiką iš anksto išmaišant komponentus reikalingoje mineralinės alyvos dalyje, o visa tai sumažina hermetinimo skysčio savikainą ir sutrumpina jo gamybos laiką.The proposed method allows the sealing fluid to be obtained, depending on its purpose, by adding only the target components, not the universal sealing fluid, and shortens its production time by premixing the components in the required amount of mineral oil, all reducing the cost of sealing fluid and shortening its production time.
Pasiūlytu būdu pagamintas hermetinimo skystis užkerta kelią bakųakumuliatorių koroziniam irimui bei pagerina juose laikomo vandens kokybę.The sealing fluid produced in the proposed manner prevents the corrosion of the tank accumulators and improves the quality of the water they contain.
