Chloroprene caag (CR), oo sidoo kale loo yaqaan caag chloroprene, waa elastomer ay soo saartay alfa polymerization of chloroprene (ie, 2-chloro-1,3-butadiene) oo ah alaabta ceeriin ee ugu weyn.Waxaa markii ugu horreysay sameeyay Wallace Hume Carothers oo ka tirsan DuPont Abriil 17, 1930. DuPont waxay si cad ugu dhawaaqday Noofambar 1931 inay ikhtiraacday caag chloroprene oo si rasmi ah u soo bandhigtay suuqa 1937, taasoo ka dhigaysa chloroprene caag noocii ugu horreeyay ee caag-samaysan ee warshado lagu soo saaro. .
Guryaha caagga ah ee Chloroprene.
Muuqaalka Neoprene waa caano cad, beige ama buro khafiif ah ama buro, cufnaanta 1.23-1.25g / cm3, heerkulka kala-guurka galaas: 40-50 ° C, barta jajaban: 35 ° C, barta jilicsan oo ku saabsan 80 ° C, burburka 230- 260°C.Ku milmay chloroform, benzene iyo dareerayaasha kale ee organic, oo ku barara saliidda cuntada iyo saliidda macdanta iyada oo aan la milmin.80-100C waxaa la isticmaali karaa waqti dheer, iyadoo heer gaar ah oo dib u dhac olol ah.
caag Neoprene iyo qaab-dhismeedka caag dabiiciga ah waa la mid ah, farqiga u waa in kooxda koronto-neoprene neoprene beddelo kooxda methyl ee caag dabiiciga ah, taas oo hagaajinaysa caabbinta ozone, caabbinta saliidda iyo caabbinta kulaylka caag neoprene.Marka la soo koobo, waxay leedahay iska caabin cimilo oo heer sare ah, iska caabin ozone, caabbinta daxalka kiimikada, caabbinta saliidda, iwmSidaa darteed, neoprene waa mid aad u badan, labadaba sida caag guud oo ujeedo leh iyo caag gaar ah.
sifooyinka ugu muhiimsan ee jirka iyo farsamada waa sida soo socota:
1.Xoogga caagga neoprene
Noocyada jilicsan ee neoprene waxay la mid yihiin kuwa dabiiciga ah ee dabiiciga ah, iyo caaggiisa cayriin wuxuu leeyahay awood xoog leh oo xoog leh iyo dhererka jebinta, taas oo ah caag is-xoojisa;Qaab dhismeedka molecular ee neoprene waa molecular joogto ah, silsiladuna waxay ka kooban tahay kooxaha polar ee atamka chlorine, taas oo kordhisa xoogga intermolecular.Sidaa darteed, marka la eego ficilka xoogagga dibadda, way fududahay in la kala bixiyo oo la isku qurxiyo (is-xoojinta), iyo silbashada intermolecular ma fududa.Intaa waxaa dheer, miisaanka kelli waa ka weyn yahay (2.0 ~ 200,000), sidaas darteed xoogga xajinta ayaa ka weyn.
2.Dib u caabbinta gabowga oo aad u fiican
Atamyada chlorine-ka ee ku xidhan isku-xidhka labanlaabka ah ee silsiladda molecular neoprene waxay sameeyaan isku-xidhka laba-jibbaaran iyo atamka koloriinku waxay noqdaan kuwo aan shaqayn, sidaas awgeed xasilloonida kaydinta caaggeeda vulcanized ayaa wanaagsan;Ma fududa in lagu saameeyo kulaylka, ogsijiinta iyo iftiinka jawiga, taas oo muujinaysa caabbinta da'da ee aad u fiican (iska caabinta cimilada, caabbinta ozone iyo caabbinta kulaylka).Iska caabbinta gabowga, gaar ahaan cimilada iyo iska caabbinta ozone, ayaa ah ka labaad ee kaliya marka loo eego caagga ethylene propylene iyo caagga butyl ee caagga guud ee ujeeddada, aadna uga wanaagsan caagga dabiiciga ah;caabbinta kulaylkeedu waxa uu ka fiican yahay caag dabiici ah iyo styrene butadiene, oo la mid ah caag nitrile ah, waxa la isticmaali karaa wakhti gaaban 150 ℃, waxaana la isticmaali karaa ilaa 4 bilood at 90-110 ℃.
3.Holac-iska caabin heer sare ah
Neoprene waa caagga guud ee ugu fiican, waxay leedahay sifooyin gubasho aan iskeed ahayn, xiriirka ololku wuu gubi karaa, laakiin ololka go'doonsan waa la daminayaa, tani waa sababta oo ah neoprene gubanaya, doorka heerkulka sare waa la burburin karaa iyada oo la raacayo doorka gaaska hydrogen chloride oo ka dhig dabka dami.
4.Excellent caabbinta saliidda, caabbinta dareeraha
Iska caabbinta saliidda caagga neoprene ayaa ah kan labaad oo keliya caag nitrile ah oo ka fiican caagga kale ee guud.Tani waa sababta oo ah molecule neoprene ka kooban yahay atamka chlorine polar, taas oo kordhisa polarity ee molecule.Iska caabbinta kiimikada ee neoprene sidoo kale waa mid aad u wanaagsan, marka laga reebo aashitada oksaydhka ee xooggan, asiidhyada kale iyo alkalis wax saameyn ah kuma laha.Iska caabbinta biyaha ee neoprene sidoo kale way ka fiican tahay kan caagadaha kale ee synthetic.
Waa maxay meelaha loo isticmaalo neoprene?
Neoprene waxaa loo isticmaalaa codsiyo kala duwan oo kala duwan, gaar ahaan alaabooyinka u adkaysta gabowga, sida fiilooyinka korantada, maqaarka fiilooyinka, barkinta barkinta jidka tareenada, darbiyada taayirrada baaskiilka, biyo-xireennada caagga ah, iwm.;Alaabooyinka kulaylka u adkaysta iyo ololka u adkaysta, sida suumanka gudbinta kulaylka u adkaysta, tuubooyinka, xaashida caaga ah, iwm;Saliida u adkaysata iyo kiimikooyinka u adkaysta, sida tuubooyinka, rolalka caagga ah, go'yaal caag ah, baabuurta iyo qaybaha cagafyada;alaabo kale sida maro caag ah, kabo caag ah iyo xabag, iwm.
1.Waxyaabaha daboolaya fiilada iyo fiilada
Neoprene waa u adkaysta iftiinka qoraxda, ozone adkaysi u, oo uu leeyahay non-flammability aad u fiican, waa qalabka fiilada ugu fiican ee miinooyinka, maraakiibta, gaar ahaan samaynta xidhidhka cable, laakiin sidoo kale inta badan loo isticmaalo baabuurta, diyaaradaha, fiilooyinka dabka engine, fiilooyinka kontoroolka warshad tamarta atomiga. iyo sidoo kale fiilooyinka telefoonka.Iyada oo neoprene loogu talagalay jaakada fiilada iyo fiilada isticmaalka badbaadada leh marka loo eego caagga dabiiciga ah in ka badan 2 jeer.
2.Suunka gaadiidka, suunka gudbinta
Neoprene waxay leedahay sifooyin farsamo oo aad u fiican, oo aad ugu habboon soo saarista suunka gaadiidka iyo suunka gudbinta, gaar ahaan iyada oo wax soo saarka suumanka gudbinta ay ka fiican tahay caag kale.
3.Oil tuubada u adkaysata, gasket, anti-corrosion Murari
Iyada oo ku saleysan caabbinta saliidda wanaagsan, caabbinta daxalka kiimikada, caabbinta kulaylka iyo sifooyinka kale, neoprene waxaa si weyn loogu isticmaalaa soo saarista alaabada saliidda u adkaysata iyo tuubooyinka kala duwan, cajaladaha, gaasaska iyo dahaarka qalabka daxalka u adkaysta, gaar ahaan kulaylka u adkaysta. suumanka qaada, saliida iyo aashitada iyo tuubooyinka u adkaysta alkali, iwm.
4.Gaaska, suufka taageerada
Neoprene waxay leedahay caabbinta wanaagsan iyo dabacsanaanta, qaybo badan oo baabuur oo laga sameeyay neoprene, sida muraayadaha daaqadaha, tuubooyinka gaasaska kala duwan, iwm.
5.Adhesive, dheesha
Xabagta neoprene ee ka samaysan caag neoprene ah sida alaabta ceeriin ee ugu muhiimsan waxay leedahay dabacsanaan wanaagsan, iyo caabbinta gabowga, caabbinta kiimikada iyo caabbinta saliidda, iyo xoogga isku xirnaanta sare.
Latex neoprene kuma jiraan dareerayaasha organic, sidaas darteed waxay leedahay faa'iidooyin muuqda oo ku saabsan badbaadada iyo caafimaadka, halkaas oo carboxyl neoprene loo isticmaali karo sida xabagta caag iyo birta.Caag chloroprene ah ayaa leh polarity, sidaas darteed substrate-ka isku-xidhka ayaa leh codsi ballaaran oo kala duwan, gaar ahaan dhalada, birta, PVC adag, alwaax, alwaax, aluminium, caag kala duwan, maqaar iyo dhejisyo kale.
6.Alaabooyinka kale
Neoprene sidoo kale waxaa si weyn loogu isticmaalaa goobta gaadiidka iyo dhismaha.Sida isticmaalka barkinta xumbo neoprene ee baska iyo baabuurka dhulka hoostiisa mara, waxay ka hortagi kartaa dabka;diyaarad, oo leh caag dabiici ah iyo neoprene isku-dar ah si ay u sameeyaan qaybo u adkaysta saliidda;mishiinka oo leh qaybo caag ah, gaasaska, shaabadihii, iwm;dhismaha, loo isticmaalo gaasaska dhismaha-sare, labadaba badbaado iyo naxdin;neoprene sidoo kale waxaa loo isticmaali karaa sida embankment macmal ah, interceptor on shaabadda Rafaa, daabacaadda, dheehidda, daabacaadda, waraaqaha iyo rullaluistemadka kale ee caag warshadaha Neoprene sidoo kale loo isticmaali karaa sida barkin hawo, bacda hawada, qalabka nolosha badbaadinta, cajalad koollada, iwm.
