I-PA66 (i-Polyamide 66 okanye i-nylon 66) yindawo ye-thermoplastic, yenziwa ngokufundela i-Polycondikelelo ye-Adipic Acid kunye neDipic Diamine. I-insuble kwii-soces ngokubanzi, kwaye inyibilika kuphela kwi-Cresson njalo njalo. Inamandla amakhulu oomatshini kunye nobunzima, kwaye ziqinile kakhulu. Inokusetyenziswa njengeeplanga zobunjineli, izixhobo zoomatshini ezinjengeegiya, iibheringi ezifudukayo, endaweni yezinto zentsimbi ezingeyongozi ukwenza iifowuni zentsimbi, njl njl., Kunye nezinye iimfuno ze imveliso. Inokusetyenziselwa ukwenza iintsinga zokwenziwa.
Iinkcukacha zajikelele
Yindawo ye-thermoplastic iqulathe iqela le-amil Ihlala yenziwa kwiipellets ze-cylindrical, kwaye ubunzima bemoya ye-pullamides esetyenziselwa iiplastiki ze-15,000 ukuya kwi-20,000 yeetoni. Iimpawu eziqhelekileyo ze-polyamaides ezahlukeneyo ziyi-Flame, amandla aphezulu e-subile (ukuya kuthi ga kwi-104kpa), i-455kpa), i-455kpa phantsi kweqondo lobushushu le-150 ℃ okanye ngaphezulu), indawo yokunyibilika kwe-150 ~ 250 ℃, imeko ye-molten yendlela yokuhamba ye-resin iphezulu, i-fiverand ye-1.05 ~ 1.15 (i-filler inokongezwa ukonyusa inani ukuya kwi-1.6), uninzi lwezinto ezingenabungozi. Nangona kunjalo, xa umxholo onomxholo osemzimbeni uphakame kakhulu, awulungelanga ukunxibelelana kwexesha elide nolusu okanye ukutya, kwaye kuhlala kukho imigaqo ecocekileyo yokutya kumazwe ahlukeneyo.
Iimveliso zenylon
Imbali yokwahluka kwezamane ezinemizi-mveliso ye-Polyamide i-Polyamide 66 (IE, i-NYLOLO 66), i-United States yaseMelika dupont yapapasha iisampulu zokuqala zepatent (i-nylon Fibles), ukusekwa kwesityalo sePilot Ngo-1938, ngo-1939 iiyunithi zokuvelisa ishishini lokusebenza. Ngelo xesha, ii-polyamides bezisetyenziselwa ukuveliswa kweentsinga, iintsontelo kunye nemeri. Ukusebenzisa emkhosini kwezi zixhobo kuphuhliswa ngexesha lemfazwe yehlabathi yesibini, kwaye iifilimu kunye neplastiki zaveliswa emva kwemfazwe. Ngo-1941 wabona ukuqala kwemveliso ye-Polyamide 6 eJamani, kulandelwa luphuhliso lwe-Polyamide 610. Ngo-1950 kwabona ukuphuhliswa kwe-Polsamide 11 eFransi. Ngo-1958 wabona imveliso yokuvavanywa ngempumelelo ye-Polyamide i-1010 eTshayina, kunye ne-co-polyomide e-USSR. Ngo-1966 wabona imveliso yamandla enkulu ye-Polyamide 12 kwinkampani yehemicali ye-hess kwiRiphabhlikhi yaseJamani. Ngo-1972, i-dupnt yase-US yaqonda ukuba ukuveliswa kwemveliso ye-upolyamatide yenhokoti. Iminyaka engama-70 kamva, ukuguqulwa kwezibuko kuvuselele umdla omkhulu, ngakumbi uphuhliso lwe-petrochemical kunye ne-Perowidees Deatiments ye-oyile, indleko ikhula minyaka le, ukuze i-polyamide iphuhlise kwiklasi ye Iintlobo, zinokuhlengahlengiswa kwiintlobo ngeentlobo zezixhobo zePolymer.
Intsebenzo
I-PA66 Polyamide 66 okanye i-NYLOLO 66 I-Chemical kunye nePhepha leMikhali ye-PA66 inendawo ephezulu yokunyibilika kwizixhobo ze-POLLYAMAide. Yinto ene-crystalline ye-crystalline.pa66 igcina amandla ayo kunye nokuqina kwamaqondo obushushu aphezulu. Iziphumo zokuhlela kwi-hygroscoficity ngokuzinza kwejometri kufuneka kuthathelwe ingqalelo ngexesha loyilo lwemveliso. Ukuphucula iipropathi zoomatshini we-PA66, iintlobo ezahlukeneyo zeemodyuli zihlala zongezwa. Iglasi yeyona nto iqhelekileyo, kwaye ngamanye amaxesha irayisi ye-spouber efana ne-EPDM kunye ne-SRR yongezwa ukuphucula ukumelana kwempembelelo. I-PA66 ine-viscofity ephantsi kwaye ke ukuhamba kakuhle (kodwa akulunganga njenge-PA6). Le propati inokusetyenziselwa ukubahlulahlulahlulahlulahlulahlulahlula. I-viscosity yayo inovelwano kuguquko lweqondo lobushushu.pa66 shrinkage phakathi kwe-1% ne-2%, kunye nokongezwa kwe-fiber ye-fiber yeglasi inokunciphisa i-0.2% ukuya kwi-1%. I-Shrinkage kwindlela yenkqubo kunye nesikhokelo esijikelezayo kwindlela yenkqubo enkulu. I-PA66 i-solvent yokunganyangeki kwizinyithi ezininzi, kodwa ayichasanga kangako kwii-acids kunye nezinye iiarhente ezithotyelweyo.
Ipropathi yomzimba kunye neekhemikhali
I-PA66 ye-Plaw yeplastiki yeplastiki ye-translucent okanye ye-opaque opalescent okanye nge-rystalline ye-rystalline polymer, ngeplastikhi. Ukuxinana (G / CM3) 1.10-1.14; amandla amanqindi (MPA) 60.0-80.0; I-Rockwell Hard 118; Inqaku lokunyibilika 252 ° C; Ubushushu bobutsha -30 ° C; iqondo lokungalunganga le-thermal elingaphezulu kwe-350 ° C; Ukuqhubeka kokumelana nobushushu 80-120 ° C; amandla empembelelo (kJ / m2) 60-100; amandla aqingqiweyo (MPA) 1 00-120; Ukumelana nobushushu bukaMartin (° C) 50-60; I-freeXoul imodyuli ye-elaistity (MPA) 2000-3000; Ukunganyangwa kwevolumu (ωcm) 1.83 × 1015; Ukulingana kwe-2.5%; Delectric rhoqo 1.63.
Ifomula yekhemikhali: [-NH (Ch2) 6-NHCO (i-Alkalis, i-Alkalis, iAlkalis, i-Alkalis, i-Hydrocar, i-etter, kunye nolunye uKhekelo
I-PA66 inomgangatho ophezulu wokunyibilika kwizinto ze-POLLYAMAide. Kuyilo lwemveliso, i-PA66 Shrinkage phakathi kwe-1% ne-2%.
Ngoku jikeleza imarike ngamanzi amaninzi anokulahlwa ngokuguqulwa, okufanayo unokufumana ubume bezinto ezibonakalayo zezinto zentsusa, ngelixa ixabiso linexabiso eliphantsi kunezixhobo ezinqabileyo, ukuze uninzi lwabathengi lusindisa inani elikhulu le Ixabiso.
Ukulungiswa kwePolyamide
Eyona ndlela iphambili kukongeza isixa esifanelekileyo sezinto ezongeziweyo kwinkqubo ye-polymerizazazazaza okanye isebenze, ukuze unike i-resin iimpawu ezahlukeneyo, ukuze ilungele iintlobo ezahlukeneyo. Izongezo eziqhelekileyo ezisetyenzisiweyo zezi: ① uzinzo. Kubandakanywa ukuzinza kobushushu kunye nokuzinza okukhanyayo, okunokuphucula ngokuchasene ne-oxidetion kunye nokunganyangeki kokukhanya kwe-Pollide ukuvelisa i-nylon nylon i-anting nylon. Ukuba ukongeza i-carbon ye-carbon emnyama i-2% (umgangatho), i-polyamide inokusetyenziswa ngaphandle kwexesha elide. ② I-Giber esetyenziswayo ye-fiber esetyenzisiweyo. Yenziwe ngoqinile i-nylon eyomeleze i-wigalon, inciphise i-curp, kwaye yenza ukubumba kwemveliso yemveliso kuya kuba mncinci, kuya kuba lusizi olungcono. Iphuculwe ngeentsinga zentsimbi, hayi kuphela imodyuli ephezulu, kodwa ikwaqhuba. Iiminerals nazo zinefuthe elihle lokuphucula, kwaye zenze ukuqhubekiswa kunye nokuncitshiswa okulula, iindleko. I-Molybdenum ilahlekile kwaye i-polytetrafluorofyyyyyyyyyyyyyathyne ikwanobungqina obuqiqiweyo, kwaye inokuphucula ukuchitha. ③ I-Sunteivers. Isetyenziselwa ukuvelisa i-rocrystalline nylon, inokukhawulezisa ixesha lokudilizwa, ukuze umjikelo wokubumba unqunyulwe ngama-20% ukuya kwi-30%. Ukongeza, kuxhomekeka kwisicelo, iiplasitizeli kunye nee-nyibionts zinokongezwa.
Enye indlela yokuguqulwa kukugcwaliswa kwe-copolymerization, i-copolymerizer ye-nylon yizinto ezilungileyo zokusongela kunye nezinto zokutywina kwegasket; I-Polyamide kunye nePolyoolefin ibhloko yokugcwalisa, inokuphucula kakhulu amandla empembelelo kunye nozinzo oluninzi, kwaye lunciphise i-ansurition yokufuma, kwaye ide yenziwe lula, iplastiki ephantsi. Le ndlela isebenzayo yokusombulula iziphene ze-Polyamide yenye yezikhokelo zophuhliso lweentlobo eziguqulweyo kwiminyaka yakutshanje.
Isebenzisa
Iimveliso zeplastiki zePlayside zisetyenziswa ngokubanzi njengeentlobo ngeentlobo zeenxalenye ze-Pounical kunye neeNdawo eziPhezulu, ii-pumples, i-pubilings, i-oyile, iintambo ze-OTO Ukunamathela, iibhokisi zebhetri, ioyile yombane, uqhagamshelo lwentambo njalo njalo. Kukwakhona netheyipu yokupakisha, ifilimu yokutya (ukutya okuphekiweyo kwifilimu ephezulu yefilimu kunye neziselo ezipholileyo ngemveliso yefilimu) yemveliso yefilimu) inkulu kakhulu. Inkampani e-United States ukuya kwiPlassics ye-Polsamide ukuze ifumane intsingiselo yokuphendula, ikwabizwa ngokuba yi-rim nylon, ininzi kakhulu kwi-rim ye-rim nylon ye-rim ye-rim ye-rim Ngezinto zentsimbi, kwimveliso yokwenza imveliso yemoto ukunciphisa ubunzima, ukonga amandla kunye nokunciphisa iindleko kufumene enye indlela.
Iindidi eziphambili zeentsinga ze-Polyamide (Aliiphatic) yinylon 66 noNylon 6, eyokugqibela ikwabizwa ngokuba yinylon. Banamandla aphezulu, ukomelela kakuhle, owona msebenzi uphezulu we-arasion kwimigca ye-itayim, ukumelana nokusebenza okuninzi kunye nokungakhathali kufutshane ne-polyester, ngaphezulu kunabanye abathunywa. Banomsindo wobushushu obulungileyo, kodwa ukukhanya okungalunganga kunye nokuxhathisa ubushushu. I-Pollibemide Fible Fible ingenziwa zibe ziisokisi, impahla yangaphantsi, ihempe, i-sweatshi, ihempe, i-skie, imvula, njl.; Iintsinga ze-staples zingadityaniswa ngekotoni, woboya kunye neentsinga ze-viscose, ukuze ilaphu liyithintele kakuhle namandla. Ingasetyenziswa njenge-velcro, iikhaphethi, ilaphu lokuhombisa njalo njalo. Ngokwemveliso ikakhulu isetyenziselwa ukwenza intambo yentambo, ibhanti yokuhambisa, umnatha wokuloba, intambo njalo njalo.
