Ziva zvese nezve yakanyanya kupisa nylon

Yakakwira-tembiricha nylon (HTPA) ipurasitimu yekupisa-inodzivirira inogona kushandiswa kwenguva yakareba yenguva pa150 ° C. Icho chidimbu chesipolitiki chakagadzirwa nePolycononsation of terephthalic acid uye 1,6-hexaneMine. Mapoka makuru ekupisa kwakanyanya nylon anosanganisira aliphatic pa46, semi-aromatic pa4t, pa6t, pa9t, PA22T, mxdt Yakakwira-tembiricha nylon mumaperemberi, kupokana kwemuviri uye nemakemikari kuve nekusagadzikana kwakakura uye kusimba kwakanyanya uye kugadzikana, zvinowedzera, zvinoshandiswa zvakanyanya, zvinoshandiswa zvakanyanya mumotokari, magetsi uye zvemagetsi, mechanical engineering uye mamwe minda.

Hunhu hwekumusoro-tembiricha nylon

(1) kupisa kwakanyanya

Iyo inopisa inopisa tembiricha ndeye 280 ℃ (1.8mpa), uye kuenderera mberi kwekushandisa tembiricha ndeye 180 ℃.

(2) zvivakwa zvinokambaira

HTPA's Crystallinityityityity inotendera kuti irambe yakanyanya kuomarara pakupisa kwakanyanya (yakakura kupfuura 120 ℃), neAluminium - Sesimbi-sesimbi-sekushanduka-simbi, kushushikana uye kukanganisa uye kukanganisa.

(3) Yakanakisa dimensional kurongeka uye kugadzikana

Iyo molecular chimiro cheHTPA ine zvinetso zvinonyomba mumanyorerwo emachira emachira, ayo anoita iyo molecular chimiro chimwe nechimwe cheketeni zvishoma nezvishoma.

(4) Kemical Resistance

Polyamide zvinhu zvine basa rakanaka kumakemikari mazhinji. Semamwe zvinhu zvekushandisa polyam, Htpa haisi yekusarudzika, kunyanya mune yakanyanya kupisa mafuta uye kurwisa mafuta kwakanaka kwazvo.

(5) kunyorova kunyorera

HTPA FILER-yakasarudzika zvigadzirwa zvine yakaderera kunyorova kwekunyora, iyo inongova hafu yeiyo yakaenzana girazi fiber-rakasimbiswa pa46 chigadzirwa. Iyi yakaderera moisture yekunyungudza inogona kuchengetedza zvakanyanya kuomesa mutengo kune vatengi, uye kugadzirwa kwechigadzirwa chakazara kuri nani.

(6) kuomarara

HTPA's yakanaka kwazvo kukanganiswa kunoita kuti ive iyo zvinyorwa zvekusarudza kune zvinodiwa zvigadzirwa.

Mhando dzekwakakwirira-tembiricha nylon

(1) PA46

PA46 IYO ALIPHINOTIC Polyamide inodziya kubva kuButanediamine uye Adipic acid. Kuenzaniswa nePA6 uye PA66, PA46 ine huwandu hwepamusoro hwekutarisa keteni uye hunotendera kuchema kwayo se 70% uye kunopa iyo yakanyanya kukurumidza cruntallization rate.

Iyo yekunyungudika point yePa46 ndeye 295 ° C. Kupisa kupisa tembiricha isina kusarudzika ye40

Iyo yakasarudzika chimiro che pa46 inopa iyo yakasarudzika zvivakwa zvisingagone kuwanikwa nezvimwe zvinhu. Semuridzi akazara ekodzero dzeimba yePfuma yePa46, DSM ari kuita zvishoma nezvishoma zvivakwa zvayo zvakanakisa kuburikidza nekuenderera mberi kuchinjika. Pamusoro pekushomeka kwayo kwakadzika, kwakasiyana-siyana kwakasiyana-siyana kwakadai sekukasira supering kuramba, Ultra-yakanyanya kuomarara, uye Ultra-yakakwirira-yakakwira fluidity yakagadziriswa.

Maererano nekudziya kwakanyanya, DSM muna 2008 Chinaplas yakatanga hupfumi hwaro hweStan yl Diablo, inogona kuve iri 230 【 15% kuderera.

(2) pa6t

Pa6t ndeyemiriri chaiwo weSemi-Aromatic Nylon, iyo iri polycendensed kubva hexyledediamine uye terephthalic acid. Pa6T pa6t inonyungudutsa kusvika pamakumi matatu kusvika ku370

Pa6t muAliphatic Chairs zvichibva padanho rehuwandu hwehuwandu hweBenzene rings, tichienzanisa neChiti yeShona Sezvo pa6t inoda kuunza mamwe monomers yeCopolymerization kudzikisa tete tembiricha, akasiyana monomer ratios anova kiyi yekuchinja kweP6T

MuChina, Wang Peigang uye vamwe vakadzidza maitiro ePolymeration yePalmer. Shanghai Jieshijie kambani yakabudirira zvakare kupa iyo pa6t nhevedzano yepamusoro-tembiricha inodzivirira nylon, uye yakaiswa mukugadzira.

(3) PA9T

Pa9t inovandudzwa neJapan Kuraural Kambani yega, yakadhindwa nonylenedtiamine uye terephthalic acid. Kunyangwe iyo yakafanana semi-inonhuhwirira nylon, pa9t mukugadziriswa kweiyo haidi kuderedza nzvimbo yekunyungudika, Poot yekunyungudika uye yakakwirira crystallinity, yakapihwa nekuomarara kwakanaka munzvimbo dzakakwirira dzekushisa.

Panguva imwecheteyo ine zvimwewo zveP zvigadzirwa zvisingaenzaniswi zveMakemikari Pa9t yakazara pabasa hapana mubvunzo kuti haina kujairika hutsipisa zvekusimudzira.

(4) pa4t

Sekutungamirwa kwenyika inotungamira yekakwira Butylentediamine ndiyo kiyi yezvinhu zvakabikwa pa46 Synthesis, uye iyi kasticle mukana yakagonesa DSM kuti utore kutungamira mukuvandudza pa4t seyakaiswa kumeso.

Iyi yekutanga polymer yezana ramakore 21 ine yakanakisa spatial kugadzikana, nzvimbo yakakwirira-yekunyungudika, yekushomeka kwemvura yakakwirira ichienzaniswa neDSM zvigadzirwa zveDSM, kunyangwe Pa9t.

Kuita kwakazara uye kwakanaka kwazvo kwe pa4t kuchaita kuti iite chikamu chakakosha mune ramangwana mumunda wezvemagetsi uye etcomputer yePa4t zvakare yeiyo mbodo yemusika miniaturization uye iyo centralation zvigadzirwa zvemagetsi, izvo zvinoda zvekuita zvakakwirira zvekuita.

(5) PA10T

China Cao Ming, Zhang Mingqiu, nezvimwe pane synthesis uye Coplymersization yePa10t yekunyungudika yeA10T yekunyungudika . Jinfa tekinoroji, inotungamira yepurasitiki yekushandura kambani kuChina, inoshambadzira iyi tekinoroji.

Padhani-2009 Rubber & Purastics Expo, Jinfa Zvigadzirwa Zvakaunzwa neGiredhi Vicnyl, iyo Yakanyanya Kuwedzera Kubata, Kupesana Kugadzikana Kwemuridzi-Wemahara Coler Kusvika jekiseni rinoumba maitiro ekugadzirisa.

Uyezve, zvinonzi hafu yeiyo mbichana zvinhu zvePa10 inouya kubva kuCastor uye kusimudzira kwezvinhu zvitsva-tembiricha nylon zvinhu, uye jinfa yave iyo 2nd unit muChina ine yakakwira-tembiricha-inodzivirira nylon zvinyorwa zvechina zvichitevera Shanghai Jieshijie kambani.

(6) mimwe zvigadzirwa

PPA (semi-anomatic nylon) inogadzirwa nePolycendenation yealiphatic diamine kana diamine ine chinese chindori che diamine kana diamine. Pamusoro pezvinhu zvakatsanangurwa pamusoro apa, senge pa4t, pa6t, PA9T, PA9T., kune mamwe akawanda ppa marudzi akadai sePamxd6 ne pa12T. Iyi nylon zvinhu nekuda kwechimiro chemakemikari ezvemhete zvinonhuhwirira, akasiyana madhigirii ekuvandudza kupisa kwekushisa tembiricha. Pakati pavo, dontent yakashandiswa dimethyl terephthalate (DMT) uye dodecylamine (DDMD) yekuSynthessize pa12T, ine yekunyungudika ye 296.6 ° C, iyo ine kukosha kwakasimba kwekushandisa.
