Yazi yonke into malunga nobushushu obuphezulu nylon

Iqondo lokushisa eliphezulu nylon (i-htpa) liyityhefu ebuyela ubushushu enokusetyenziselwa ixesha elide nge-150 ° C. Yinto evuthayo evuthayo eyenziwe yi-Polycondentring ye-terephthayic i-Acid kunye ne-1,6-hexaminedine. Iindidi eziphambili zeqondo lobushushu i-NYLOL liquka i-Aliphic PA46, i-Semi-Aromatic Pa4t, Pa9t, Pa1t, i-PA12T, i-PPGE ye-Aromatic, kunye ne-pppta yayo. Ubushushu obuphezulu nylon kwi-thermal, ukuchasana nombane, ngokwasemzimbeni kuyasebenza, ngakumbi kumaqondo obushushu aphezulu anobunzima obuphezulu kunye nokuzinza okuphezulu kunye nokuzinza okuphezulu kunye nokulungiswa kwentsingiselo, kusetyenziswe ngokubanzi kwinqwelo-mafutha, Ubunjineli boMbane kunye ne-elektroniki, oomatshini kunye nezinye iindawo.

Iimpawu zobushushu obuphakathi nylon

(1) Ukunganyangeki kobushushu obuphezulu

Iqondo lokushisa elishushu lingama-280 ℃ (1.8MPA), kunye neqondo lobushushu eliqhubekayo liyi-180 ℃.

(2) Iipropathi ze-Creep

I-crystallies ephezulu ye-htpa ivumela ukuba igcine ingqumbo ebalaseleyo kwiqondo lobushushu eliphezulu (elingaphezulu kwe-120 ℃), kunye ne-altisum-njengamandla, intsimbi-njengokuguquguquka, irabha kunye nokungavisisani kwembaleki.

(3) Ukuchaneka okungalunganga kunye nokuzinza

Isakhiwo se-MOLERAN I-HTPA iqulethe amakhonkco avuthayo kwicandelo le-molecular chain, eyenza imeko yemolekyuli ixhaphake rhoqo kunye ne-chain sests zithambekele ekuhambeni.

(4) Ukumelana kwamachiza

Izixhobo ze-Pollide zinokumelana kakuhle kwiichemicals ezininzi. Njengezinye izinto ze-polnamide, i-HTPA ayifani, ngakumbi kwi-oyile yobushushu ephezulu yeoyile kunye negrisi ilunge kakhulu.

(5) Ukufunyanwa komswakama

Iimveliso ze-HTPA FIBER-Reciententrated iimveliso zinokufunyanwa komswakama okuphantsi, nto leyo enesiqingatha se-fiber elinganayo ye-fiber-eyomeleleyo ye-PA46. Lo mqobo wokufumanisa umswakama unokugcina iindleko ezoyikisayo zabathengi, kwaye uzinzo lwemveliso lungcono.

(6) ubunzima

Ubunzima bempembelelo entle ye-HTPA yenza ukuba kuthathelwe ingqalelo ukhetho lokukhetha imveliso.

Iindidi zeqondo lobushushu obuphezulu nylon

(1) I-PA46

I-PA46 yi-aliphic pellamide evunyiwe kwi-butanediamine kunye ne-adipic acid. Xa kuthelekiswa ne-PA6 kunye ne-PA66, i-PA46 inenani eliphezulu le-avals ubude be-chain kunye nolwakhiwo lwekhonkco lokulinganisa, elivumela i-Crystallity ye-70 kwaye inike iqondo lekristali elikhawulezayo.

Indawo yokunyibilika ye-PA46 ngama-295 ° C. Iqondo lokungcolisa i-surtion nge-PA46 le-160 ° C, ngelixa emva kokuqiniswa kwe-fiber fiber, ubushushu bayo obushushu bunokuba yi-290 ° C, iqondo lobushushu ixesha elide likwayi-163 ° C.

Isakhiwo esahlukileyo se-PA46 sinika ipropathi eyahlukileyo engenakufezekiswa zezinye izinto. Njengomnini opheleleyo wamalungelo epropathi ye-PA46, i-DSM iphuhlisa ngokuthe ngcembe iipropathi zayo ezilungileyo ngokuguqulwa okuqhubekayo. Ukongeza kulwando lwamaqondo obushushu obuphezulu oluphezulu, izicelo ezahlukeneyo ezizodwa ezifana nokuxhathisa i-arasion enkulu, i-ultra-rigidity ephezulu, kunye nolwelo lwe-Ultra.

Ngokumalunga nokunganyangeki kobushushu obuphezulu, i-DSM ngo-2008 Chineplas isungule i-China eNtsha ye-STAN YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YL YLY Iipesenti ezili-15.

(2) I-PA6T

I-PA6T ngummeli oqhelekileyo we-semi-ivumba le-nylon, elivela kwi-hexlem kunye ne-terephthamic acid. Inqaku elicocekileyo le-PA6T ukuya kuthi ga kwi-370 ℃, kweli nkunkuma ichithwayo, ayinakuba sisibungu se-thermoplatic, ngoko ke ukujikeleza kwemakethi ye-PA6T emva kokunyibilika kweyona ndawo inyibilikayo ye-copolymer okanye entsokothileyo.

I-PA6T kwi-Aliichatic Chain esekwe kulwaziso lwenani elikhulu le-Bezene, xa kuthelekiswa ne-PA6 ye-PA6, i-PA66, i-PA6T inesitayile esiphezulu, ukuzinza komhlaba okuphakathi kunye nokungamelana nobushushu obuphakathi. Kuba i-PA6T ifuna ukwazisa ezinye izaziswa ze-copolymer ukunciphisa ubushushu be-melt, umyinge ohlukeneyo baba sisitshixo sokutshintsha kwe-PA6T sinegumbi elininzi lokuphuhlisa.

E China, uWang Peigang kwaye abanye baye bafunda inkqubo ye-Polymerizazazazari ye-PA6T / 66 i-copolymer enemixholo eyahlukileyo yomkhana ovuthayo kunye nokumelana nobushushu. Inkampani yeShanghai Jieshijie ikhuphe ngempumelelo nothotho lwe-PA6T ye-NYLOn enganyangekiyo, kwaye ifakwe kwimveliso.

(3) I-PA9T

I-PA9T iphuhliswa yi-japjaray yenkampani yedwa, i-polyconing ene-nonyledine kunye ne-terephthayic acid. Nangona i-nylon efanayo ye-nylon, i-PA9T ekuqhubeni okufanayo akufuneki ukuba ifake i-PA6T yokuthoba indawo yokunyibilika nge-chigy ye-rapolyling ye-chigy ye-chiger ye-chig yeglasi (i-125 ° C) kunye ne-crystallies ephezulu, enikwe amandla amahle kwiindawo zobushushu obuphezulu.

Kwangelo xesha ikwanayo nezinye izinto ze-PARS ezingenakuthintelwa kukungakwazi ukwenza imichiza engafaniyo yemichiza, yesibini kuphela kwi-PPS, kunye nokuthathwa kwamanzi yi-0.17% kuphela, eyona iphantsi yayo yonke i-PA. Intsebenzo ebanzi ye-PA9T ngokungathandabuzekiyo i-nylon enganyangekiyo yemveli engcono, kwaye ngokwandiswa okuqhubekayo kwemveliso, iindleko zeendleko zayo ziya kusondela kwindleko ze-PA, ke i-PA9T inokwenzeka yophuhliso.

(4) I-Pa4T

Njengomvelisi ophambili wehlabathi weqondo lobushushu nylon (PA46), i-DSM inenkqubo yehlabathi ye-Butylidine. I-Butyledine yeyona nto iphambili kwi-PA46 ye-Synthesis, kwaye esi sibonelelo setekhnoloji senze ukuba i-DSM ikhuphe i-DSM yokukhokela ekuphuhliseni i-PA4T njengezixhobo ezibukhali.

Le nkulungwane yokuqala ye-21 yenkulungwane yokuqala inozinzo oluhle kakhulu lomhlaba, igosa elikhokelayo elikhokelayo, indawo elula yokunyibilika, ubunzima bemveliso ephantsi, kwaye bonisa i-Ultra-Onlication I-APREAL BREERE YAMA-DSM, nkqu ne-PA9T.

Intsebenzo ebanzi nenobuchule ye-PA4T iya kwenza ukuba ibe nenxaxheba ebalulekileyo kwixesha elizayo kwicandelo lezicelo ezinganyangekiyo ngamaqondo obushushu anjenge-PA4T, njl njl. Ungenelelo lweemveliso ze-elektroniki, ezifuna izinto eziphezulu zokusebenza.

(5) I-PA10T

I-China Ming's Cao, Zhang mingqiu, njl njl. . I-jinfa itekhnoloji, inkampani ekhokelayo yeplastiki e-China, intengiso yeTekhnoloji.

Kwirabha ka-2009 kunye ne-Exporithi yePlastiki, uJinfa avele nge-PA10T imveliso ye-PATYL, enokuzimela kwiTyransi ye-Eltra, enobuchule obukhulu, ukunyangwa okukhulu, ukunyangwa okuqinisekileyo kwamanzi, ukuxhathisa i-CORTE COOR, Inaliti yokungena.

Ngaphezu koko, kuthiwa phantse isiqingatha sezinto ezingafunekiyo ze-PA10t ivela kwi-castor, eyona nto ibaluleke kakhulu kwindalo yokusebenza ngokugqibeleleyo, ibonisa ukhuphiswano olunamandla lwentengiso. kunye nophuhliso lwezinto ezintsha ze-nylon zeqondo elitsha le-nylon, kwaye i-jinfa sele iyiyunithi yesi-2 e-China eneTekhnoloji yokuHlanganisa i-Nylon enganyangekiyo kwi-hingern.

(6) ezinye izinto ze-PPA

I-PPA Ukongeza kwezinto ezichazwe apha ngasentla, ezinjenge-PA4T, i-PA6T, i-PA9T, i-PA9T, i-PA4T, i-PA10T, zininzi ezinye iintlobo ze-PPA ezifana nePamxd6 kunye ne-PA12T. Ezi zixhobo zenylon ngenxa yesakhiwo sekhemikhali sesakhiwo se-Aulematic, siziidigri ezahlukeneyo ukuphucula ubushushu bokugqwetha ubushushu. Phakathi kwazo, i-DUPE isebenzisa i-Derethyl Terephhthalate (DMT) kunye ne-Dedecylamine (DDMD) ukuya kwi-PA12T, inyibilike ye-296.6 ° C, enexabiso elinamandla.
