Itandukaniro mu gutunganya Rubber isanzwe ugereranije n'iy'ubukorikori

Ibintu by'ingenzi byakunzwe

• Icyuho nyacyo ni ukwisubiramo, si ubutabire: gukwirakwiza ibicuruzwa muIbikoresho bya Mooney 8-12 bya rubber karemano ugereranyije na MU 3-5 bya SBR, NBR cyangwa EPDMuturutse ku mucuruzi umwe.
• Imbaraga z'icyatsi kibisi zihindura imiterere yawe yo gukata10-30 ku ijana by'umuvuduko w'ibiryokuri gauge imwe ya 0.5 mm, hamwe na silicone ku mpera buhoro.
• Gukuraho ubushyuhe bw'amaraso mu buryo bwa Cryogenic kuri-Dogere selisiyusi 150Itwikira buri polimeri isanzwe kuko ihindagurika ry'ibirahure riba hagati ya dogere -125 na dogere -20 gusa, ariko urumuri rworoshye rwa silicone rusohoka bitewe n'imbaraga z'umwuka gusa.
• Silicone na FKM ubusanzwe bikeneraUbushyuhe bwa dogere selisiyusi 200-250 nyuma yo gukira amasaha 4-24; ubusanzwe irangizwa nyuma yo gukaraba.

Igisubizo kigufi:Rubber karemano n'urubber y'ubukorikori bitandukanye mu gutunganya ahantu hane hatwara amafaranga:imiterere y'itsinda ku bikoresho biri muri icyuma gikata, imbaraga z'icyatsi kibisi ku gikoresho gikata, uburyo bwo gucika kwa flash ku gikoresho gikuraho ubushyuhe, ndetse niba igice gikeneye gusubizwamo umuti wa kabiri.. Rubber karemano ikwirakwiza ibice 8-12 bya Mooney hagati y’ibice ariko ifata neza imiterere yayo, bityo ubushobozi bwo gukata bushobora kuba bwinshi. SBR, NBR, EPDM, FKM na silicone bihura neza ariko bifite imbaraga nke z’icyatsi kibisi kandi akenshi bikenera dogere selisiyusi 200-250 nyuma yo kuvurwa NR itigeze isaba.

Umurongo w’umusaruro ntutakaza amafaranga muri laboratwari y’ubutabire. Utakaza amafaranga iyo umurongo urambuye munsi y’umuzingo w’ibiryo, iyo amarira atangiye gucika aho kuvunika, cyangwa iyo itsinda ry’ibiryo rikize vuba 15% kurusha irya nyuma. Iyi mfashanyigisho ikurikira igice kuva ku bicuruzwa bijya mu bindi kugeza ku gupakira, kandi ikagaragaza gusa itandukaniro rituma imiterere ihinduka.

Ni iki mu by'ukuri gitandukanya peteroli karemano n'iya sintetike mu gukora?

Itandukaniro rigera ku isoko ni uko ibintu bishobora gusubiramo, ntabwo ari imiterere ya molekile.Rubber karemano ni cis-1,4-polyisoprene iva mu biti bya Hevea kandi igapimwa n'umwanda, ivu n'ibintu bihindagurika. Kubera ko idakozwe ku ntego runaka, ubona icyo igihembwe cyakozwe cyose. Rubber y'ubukorikori, ishyirwa mu byiciro biri munsi yaISO 1629bikozwe mu muryango, bihindurwa nk'ibisobanuro.

Kubera ko ikintu kimwe gishyirwa mu byiciro ikindi kigashyirwaho, NR ihindura igenamiterere ryawe naho icyuma gikozwe mu buryo bwa sintetike kigahindura impamvu zawe.Ubwo buryo bwo kudahuza busobanura itandukaniro ryose rifatika riri hepfo.

Kuki guhuza kw'itsinda ari byo bigena uburyo bwo kwihanganira ibintu mu buryo busanzwe?

Kubera ko buri gipimo cyo gukata ukoresheje mu by'ukuri ari igitekerezo cy'ubushyuhe. A Imashini ikata umurongo wa CNCIfata neza cyangwa ikagabanya 0.1 mm y'uburyo bwo kugaburira kandi ikagabanya ubugari bwa 0-20 mm kugeza ku minota 80, ariko gusa mu gihe ikintu cyinjira mu cyuma gifite ubukana nk'uko resept ibivuga.

Rubber karemano igomba gusya mbere yo kuvanga, bityo ikakugeraho ifite amateka yo gukata atandukanye cyane. Mu bicuruzwa by'abakiriya, NR lots ikunze gusya units 8-12 za Mooney (ML 1+4 kuri dogere selisiyusi 100) mu gihe SBR, NBR na EPDM lots zisya units 3-5 MU - agaciro gasanzwe dukurikije ubunararibonye bwacu.

Gukwirakwira kwa MU 8-12 ni ukuzamuka kwa 15-20% mu gukomera kw'ibice bimwe., bihagije kugira ngo bihindure uburyo agace k'umugozi gatera, uko gasubira inyuma nyuma y'icyuma, ndetse niba isura yaciwe ari kare cyangwa yacitse.

Imibare ikwirakwira ni agaciro gasanzwe dukurikije ubunararibonye bwacu, ntabwo ari imipaka ya kataloge - reba ukurikije uko wabibonye.

Ni hehe Rubber isanzwe n'iya sintetike zicikamo ibice iyo zikuraho Flash?

Itandukaniro riri mu buryo flash inanirwa, ntabwo ari mu bwinshi bwayo.Umupira w'urubura usanzwe urakora neza kandi ugacikamo imigozi, umupira wa SBR na NBR uracikagurika, kandi umupira wa silicone ntuba ukomeye bihagije ku buryo ushobora gukurwaho.

Ubukonje ni bwo buryo bwo kugereranya buri wese. Impinduka z'ikirahure ziva kuri dogere selisiyusi -125 kuri silikoni zikagera kuri dogere selisiyusi -20 kuri FKM, bityo reroimashini ikuraho aside y'amazi ikoresheje icyuma gishyushya amazikuri dogere selisiyusi -150 bishyira byose munsi y'aho bicika intege. Imashini yacu ya LN2 ifata litiro 80 z'umuvuduko w'umuzingo (15-20 kg by'ibice bito) kandi ikazenguruka mu minota iri munsi ya 8 kuri 20-70 RPM hamwe n'igipimo cyo gutsinda kiri hejuru ya 98%.

Cryo ntabwo ari yo isanzwe. Flash yoroshye kandi ikomeye kandi ikora neza ihita igaragara hamwe naimashini ikoresha umwuka ikuraho imbaraga z'umwukaku gipimo cya 4 kg/umunota, kukoubundi wakwishyura azote y'amazi kugira ngo ukore akazi, igice cy'isegonda cy'umwuka cyarangiye.. Banza ukoreshe igice cy'ibisigazwa kuri dogere selisiyusi -80 hanyuma umanuke dogere 10 icyarimwe; ahantu hashyushye cyane hashobora kunyura mu buryo bwa flash yawe niho hatuma azote ikomeza kuboneka.

Ese ibinyabutabire bya sintetike bikeneye uruziga rwa kabiri rwo kuvura?

Akenshi yego, kandi agapira karemano gakunze kuba oya.Ubusanzwe NR vulcanisation irangirira mu gikoresho cyo gucapa. Silicone na FKM bikenera gukurwaho nyuma yo kuvurwa kugira ngo bikureho ihindagurika ry’ikirere no guhuza neza, cyangwa se uburyo bwo gukomera no gukanda bugakomeza kugenda nyuma yuko ibice bishyizwe mu gasanduku.

Igikoresho gikwiye niifuru ikoresha ibyuma bito bito kugira ngo ikoreshwe mu buryo bwa kabiri, ntabwo ari ugukanda kwa kabiri. Ibikoresho byacu bya XCJ-K600 (600 L) na XCJ-K900 (900 L) bikoresha ubushyuhe bw'icyumba kugeza kuri dogere selisiyusi 280 ku gishyushya cya 10.5 kW, bitwara 3,000 CBM/H by'umwuka binyuze mu ngoma ifite impande enye kugira ngo ubuso bwose bubone ubushyuhe bumwe, kandi byemere igihe icyo ari cyo cyose cyo kuvura kiva ku masaha 0 kugeza 99.99.

Shyira umuti wa nyuma yo gukira ku ikarita yo guteka aho kuwushyira mu mutwe w'umuntu ukoresha.Idirishya risanzwe ry'amasaha 4 rihinduka amasaha 6 rihindura ubukana n'uburyo bwo gukanda, kandi hariho uburinzi bubiri bwo gukabya ubushyuhe kuko ikirahure cya FKM kidakira kidakira.

Ni gute gucika intege bikubuza kwihanganira mbere yo gukata ikintu icyo ari cyo cyose?

Kugabanuka niho igice giciwe neza kiba igice kitari cyo.Kugabanya uburebure bwa 1.5-4% bivuze ko uburebure bw'igika bugomba kugabanywamo kimwe hakuwemo ishusho y'igika, ntabwo bushyirwa ku gipimo cy'igishushanyo.ASTM D2000ishyiraho ibyiciro by'ubukana n'ubworoherane ariko ntabwo igabanya, bityo umubare ugomba kuva mu igeragezwa ryawe.

Iyo gasket ya 50.0 mm igabanutseho ikeneye gukatwaho 51.5 mm. Ifite 50.0 mm kandi igice cyayo kiba cyamaze kuba gito kuri 1.5 mm mbere yo kuyigenzura - inenge umukozi adashobora kubona kandi umukiriya ntazemera.

NR yimuka 1.5-3% kandi ikagabanuka cyane mu ngano kurusha uko imeze, kuko iminyururu yerekeza mu gihe cyo gusya. Silicone na FKM byimuka 2-4% kandi bigasubiza ubushyuhe bwinshi kurusha igihe, bityo resept imwe ku kindi gikoresho ishobora kugwa hanze y’ubworoherane.

Ni iyihe nzira yo gusukura ijyanye n'iyihe polymer?

Huza icyo gikoresho gikozwemo n'icyo hejuru yacyo itwaye, ntabwo ari icyo igice gikozwemo.Ibice bya NR biza bivangwa na talc cyangwa isabune ibice bya sintetike bidatwara, kandi NR irabyimba mu mazi mu gihe silicone itabyimba.

Itsindaimashini isukura kandi yumisha imashiniXCJ-QXJ 600 ikoresha ingoma ya 304 itagira umurambararo ifite umurambararo wa mm 600 na mm 1.000, ifata kg 15-30 kuri buri mutwaro kandi ikora amatsinda atatu y’ibice bitandatu. Ikoresha litiro 20 ku munota (toni 0.1 kuri buri minota 6 yoza) na 2.5 kWh kugira ngo ikoreshwe mu minota 20 isukuye kandi yumuke kuri 12 kW / 380 V, ifite imiyoboro izunguruka idasiga ahantu hadasobanutse.

Kuri NR, koresha amazi make cyane akuraho ivumbi, kuko amazi menshi abyimba igice nyuma yo kugisuzuma. Kuri silikoni, icyo gice cyongeraho amazi gihita gihinduka: amazi gusa asigarana agahu gatuma umukiriya ananirwa gukora neza.

Ni gute wakongera kwemeza umurongo wa Compound nshya?

Ongera wemererwe mu ntambwe eshanu, kandi ntusimbuke iya mbere.Inyinshi mu mpinduka z’ibikoresho zananiwe zirananirwa kubera ko nta mbanzirizamushinga zanditswe, bityo nta muntu ushobora kwemeza icyahindutse.

1. Konjesha imiterere ije.Andika ubukana bwa Mooney, ubukana, uburemere bwihariye n'umubare w'ibice bitatu mbere yo gukora ku kintu runaka.
2. Ongera ukate ikintu cya mbere ku muvuduko utatu wo kugaburira.Komeza umuvuduko ukabije kandi uhoraho, kuko umuvuduko wiyongereye ku kintu gito cy’icyatsi kibisi kigura gusa ibisigazwa.
3. Shaka idirishya ricitse ku bisigazwa.Tangira kuri dogere selisiyusi -80 hanyuma umanuke dogere 10 kugeza igihe ubushyuhe bucikiye aho gucika.
4. Ongera ubare uburebure bw'igikato uhereye ku kugabanuka kwapimwe.Pima ibice bitanu amasaha 24 nyuma yo gukira, ntubipime ku munsi, kuko ibyinshi mu bice bigabanuka birangira muri iryo dirishya.
5. Andika resept nyuma yo gukira ku muntu ugenzura imiterere y'indwara.Igipimo cyo guhagarara, ubushyuhe bwo gufata, igihe cyo gufata n'igipimo cyo gukonjesha, byose uko ari bine, si aho byagenwe gusa.

Umwanzuro: Ni iyihe nyandiko ukwiye gukoresha mu buryo busanzwe?

Shyiraho uburyo busanzwe ibikoresho igenzura ryawe rishobora kugenzura.Imvange y’ubukorikori ifite MU 3 igufasha gukora isuzuma rikomeye kandi ikanagabanya isuzuma ry’ingingo ya mbere, ibyo bikaba bifite agaciro kurusha imiterere iyo ari yo yose. NR ifata umwanya wayo aho ubushobozi bwo kwihanganira no gucika intege kw’amarira ari ingenzi kuruta gusubirwamo - hanyuma ukagura ubushobozi bwo kwihanganira ibintu ukoresheje umuvuduko muto wo kurya no gukaraba mu buryo bugufi.

Umuryango uwo ari wo wose ukoresha, igenamiterere riba muri mashini, ntabwo riri muri polymer. Ohereza imiterere yawe, ingano na flash hanyuma tuzahuzagukuraho ubushyuhecyangwa kugabanya uburyo bwo kuyishyiraho.
