Rubber ya Chloroprene (CR), izwi kandi nka chloroprene rubber, ni elastomer ikorwa na alpha polymerisation ya chloroprene (ni ukuvuga 2-chloro-1,3-butadiene) nkibikoresho nyamukuru.Yakozwe bwa mbere na Wallace Hume Carothers wo muri DuPont ku ya 17 Mata 1930. DuPont yatangaje ku mugaragaro mu Gushyingo 1931 ko yahimbye reberi ya chloroprene ikanayimenyekanisha ku isoko mu 1937, bituma rebero ya chloroprene iba ubwoko bwa mbere bwa reberi ya sintetike yakozwe mu nganda. .
Ibikoresho bya Chloroprene.
Kugaragara kwa Neoprene ni amata yera, beige cyangwa ibara ryijimye ryijimye cyangwa ibibyimba, ubucucike 1.23-1.25g / cm3, ubushyuhe bwikirahure: 40-50 ° C, ahantu hasenyuka: 35 ° C, ahantu horoha nka 80 ° C, kubora kuri 230- 260 ° C.Gushonga muri chloroform, benzene hamwe nandi mashanyarazi, yabyimbye mumavuta yibimera namavuta yubutare nta gushonga.80-100 ° C irashobora gukoreshwa igihe kirekire, hamwe nurwego runaka rwo kubura umuriro.
Reber ya Neoprene nuburyo busanzwe bwa reberi birasa, itandukaniro nuko itsinda ryamashanyarazi ya polar itari nziza muri neoprene rubber risimbuza itsinda rya methyl muri reberi karemano, ritezimbere ozone, irwanya amavuta hamwe nubushyuhe bwa neoprene.Muri make, ifite ibihe byiza birwanya ikirere, kurwanya ozone, kurwanya imiti yangirika, kurwanya amavuta, nibindi. Imiterere yumubiri nubukanishi nabyo ni byiza.Kubwibyo, neoprene irahuze cyane, haba nkibikoresho rusange-nkibisanzwe.
Ibintu nyamukuru byumubiri nubukanishi nuburyo bukurikira ：
1.Imbaraga za rubber
Imiterere ya neoprene isa niy'ibisanzwe bya reberi, kandi reberi yacyo mbisi ifite imbaraga nyinshi kandi ndende mu kiruhuko, ikaba ari reberi yiyubaka;imiterere ya molekulire ya neoprene ni molekile isanzwe, kandi urunigi rurimo amatsinda ya polar ya atome ya chlorine, byongera imbaraga za intermolecular.Kubwibyo, munsi yibikorwa byimbaraga zo hanze, biroroshye kurambura no korohereza (kwiyubaka-imbaraga), kandi kunyerera hagati ya intermolecular ntabwo byoroshye.Mubyongeyeho, uburemere bwa molekile ni bunini (2.0 ~ 200.000), bityo imbaraga za tensile nini.
2.Kurwanya gusaza neza
Atome ya Chlorine ifatanye nububiko bubiri bwurunigi rwa neoprene ituma umurunga wa kabiri na atome ya chlorine idakora, bityo ububiko bwokubika kwa reberi yacyo yibirunga nibyiza;ntibyoroshye kwibasirwa nubushyuhe, ogisijeni numucyo mwikirere, byerekana kurwanya gusaza neza (kurwanya ikirere, kurwanya ozone no kurwanya ubushyuhe).Kurwanya gusaza, cyane cyane ikirere no kurwanya ozone, ni icya kabiri nyuma ya reberi ya etylene propylene na reberi ya butyl muri reberi rusange, kandi nziza cyane kuruta reberi karemano;ubushyuhe bwayo buruta ubwiza bwa rubber na styrene butadiene reberi, kandi bisa na reberi ya nitrile, irashobora gukoreshwa mugihe gito kuri 150 ℃, kandi irashobora gukoreshwa mugihe cyamezi 4 kuri 90-110 ℃.
3.Ibirwanya birwanya urumuri
Neoprene ninziza nziza-rusange ya reberi, ifite ibiranga gutwikwa bidatunguranye, guhura numuriro birashobora gutwika, ariko urumuri rwitaruye ruzimya, ibi biterwa nuko gutwika neoprene, uruhare rwubushyuhe bwo hejuru rushobora kubora bitewe ninshingano za hydrogène chloride gaze kandi itume umuriro uzimya.
4.Kurwanya amavuta meza cyane, kurwanya solvent
Kurwanya amavuta ya reberi ya neoprene ni iya kabiri nyuma ya nitrile reberi kandi nziza kuruta izindi reberi rusange.Ni ukubera ko molekile ya neoprene irimo atome ya chlorine atom, byongera polarite ya molekile.Imiti irwanya neoprene nayo ni nziza cyane, usibye aside irike ikomeye, aside irike na alkalis nta ngaruka bigira kuri yo.Amazi arwanya neoprene nayo aruta ayandi mashanyarazi.
Nibihe bikoreshwa muri neoprene?
Neoprene ikoreshwa muburyo butandukanye bwo gukoresha, cyane cyane kubicuruzwa bidashobora gusaza, nk'insinga z'amashanyarazi, impu z'insinga, umuhanda wa gari ya moshi, umusego w'ipine y'amagare, uruzitiro rwa rubber, n'ibindi.;ibicuruzwa birwanya ubushyuhe kandi birwanya umuriro, nkumukandara wa convoyeur utarinda ubushyuhe, ingofero, amabati, nibindi.;ibicuruzwa birwanya amavuta kandi birwanya imiti, nka hose, imashini ya reberi, amabati, ibinyabiziga na romoruki;ibindi bicuruzwa nkimyenda ya reberi, inkweto za rubber hamwe nuduti, nibindi.
1.Ibikoresho bitwikiriye insinga
Neoprene irwanya izuba, irwanya ozone, kandi ifite umuriro udasanzwe, ni ibikoresho byiza bya kabili ku birombe, amato, cyane cyane mu gukata insinga, ariko kandi bikoreshwa kenshi mu modoka, indege, insinga zo gutwika moteri, insinga zo kugenzura ingufu za atome, kimwe n'insinga za terefone.Hamwe na neoprene kuri jacketi ya wire na kabili ikoreshwa neza kuruta reberi karemano inshuro zirenga 2.
2.Umukandara wohereza, umukandara wohereza
Neoprene ifite imashini nziza cyane, ikwiranye cyane nogukora imikandara yo gutwara no gukandagira, cyane cyane hamwe nogukora imikandara yohereza kurusha izindi reberi.
3.Amavuta arwanya amavuta, gasike, anti-ruswa Murari
Ukurikije amavuta meza yo kurwanya amavuta, kurwanya ruswa y’imiti, kurwanya ubushyuhe n’ibindi biranga, neoprene ikoreshwa cyane mu gukora ibicuruzwa birwanya amavuta hamwe n’amazu atandukanye, kaseti, gasketi hamwe n’ibikoresho birwanya ruswa, cyane cyane birwanya ubushyuhe. imikandara ya convoyeur, amavuta na aside hamwe na alkali irwanya, nibindi.
4.Gasket, paje
Neoprene ifite kashe nziza kandi ihindagurika, ibice byinshi byimodoka bikozwe muri neoprene, nkamakadiri yidirishya, ama shitingi ya gasketi zitandukanye, nibindi, ariko kandi bikoreshwa nkikiraro, ikamyo itwara amabuye, ikigega cya peteroli.
5.Kwemeza, kashe
Ibikoresho bya Neoprene bikozwe muri reberi ya neoprene nkibikoresho fatizo byingenzi bifite imiterere ihindagurika, hamwe no gusaza, kurwanya imiti no kurwanya amavuta, nimbaraga zikomeye.
Neoprene latex ntabwo irimo ibishishwa kama, bityo ifite ibyiza bigaragara mumutekano nubuzima, aho carboxyl neoprene ishobora gukoreshwa nkigiti cya reberi nicyuma.Rubber ya Chloroprene ifite polarite, bityo substrate yo guhuza ifite uburyo bwinshi bwo kuyikoresha, cyane cyane kubirahuri, ibyuma, PVC ikomeye, ibiti, pani, aluminium, reberi itandukanye yibirunga, uruhu nibindi bifata.
6.Ibindi bicuruzwa
Neoprene nayo ikoreshwa cyane mubijyanye no gutwara abantu no kubaka.Nko gukoresha intebe ya neoprene ifuro intebe muri bisi no mumodoka ya metero, birashobora gukumira umuriro;indege, hamwe na reberi isanzwe hamwe na neoprene ivanze kugirango ibice birwanya amavuta;moteri ifite ibice bya reberi, gaseke, kashe, nibindi.;ubwubatsi, bukoreshwa mu igorofa yo hejuru yubatswe, haba umutekano kandi udahungabana;neoprene irashobora kandi gukoreshwa nkurugero rwibihimbano, intereptor kuri kashe nini, gucapa, gusiga irangi, gucapa, impapuro nizindi mashini zikoreshwa mu nganda Neoprene irashobora kandi gukoreshwa nko gusunika ikirere, igikapu cyo mu kirere, ibikoresho bikiza ubuzima, kaseti ifata, nibindi.
