Iplastiki yobunjineli: Umahluko wephepha le-PA6 le-PA66

1. Imvelaphi:

I-PA STOP, i-Polyamide okanye ibizwa ngokuba yi-NYLOLO, yenziwa ngokufaka i-fappes kwimilo ye-Maching kwiphepha, i-rod kunye netyhubhu yenye yeeplasitiki zobunjineli. Ineentlobo ezi-2 zezinto ezibonakalayo, i-PA6 kunye ne-PA66, ezona zixhobo ziqhelekileyo ze-nylon. Ezi zinto zimbini ziyafana kwaye zininzi izinto ezifanayo. Ke yintoni umahluko phakathi kwezi zimbini?

I-PA66 yabekwa ngempumelelo kwi-Polymer ye-PA66 ye-PA66 ye-Wallace Himes ngo-1935

I-PA6 yi-POOLMER ye-POOLMER idityaniswa ngumJamani i-Ig Gitraker esebenzisa i-caprolacam enye njengezixhobo ezibukhali Imveliso yovavanyo ye-PA6 fiber yenziwe ngo-1939, kwaye intengiso yaqhutywa yiNkampani yaseJamani ngo-1943.

2. UCWANGCISO:

Ukuhlalutya umahluko phakathi kwabo, kufuneka siqale ngesakhiwo sabo. Njengoko sonke sazi, i-PA6 yenziwa yi-Polymerization yaseCaprolactam, kwaye i-NYLOLO PA66 ifunyanwa ngokulandelelana kwe-hexmethyline kunye ne-adipic acid. I-PA6 kunye ne-PA66 inefomula yemoleyuli efanayo, kodwa ifomula yesakhiwo yahlukile, njengoko kubonisiwe kwesi sicelo ilandelayo:

Kuthe ngqo ngenxa yalo mahluko onguhlobo lomehluko, ezinjenge-Intermoecular Hydrogen Hydrogen Food yahlukile.

3. Intsebenzo

Inqaku lokunyibilika kwe-PA66 li-260 ~ 265 ° C, kunye neqondo lokushisa leglasi (ilizwe elomileyo lingama-50 ° C. Ukuxinana yi-1.13 ~ 1.16 g / cm3.

I-PA6 ye-Prestlucent okanye i-opaque i-storyry ye-polymer, inqaku leengcingo ezingama-220 ° C, uxineneyo lwe-22 ° C, i-1.8 Unamandla amakhulu omatshini, ukumelana nobushushu obufanelekileyo kunye neepropathi zombane, ukusebenza kweqondo lobushushu obuqaqambileyo, ukucima ukunyanisa kunye nokuchasana nemichiza, ngakumbi ngakumbi ukumelana kweoyile.

Xa kuthelekiswa ne-PA66, i-PA6 kulula ukuyiqhubela phambili kunye nefom, ine-grass elungileyo kumphezulu wemveliso, kwaye inoluhlu lobushushu olubanzi, kodwa inamanqanaba aphezulu okuzinza kwamanzi kunye nokuzinza okungekho phantsi kwamanzi kunye nokuzinza kweqondo eliphezulu. Inengqongqo ephantsi, indawo ephantsi yokunyibilika, ukusetyenziswa kwexesha elide kwiindawo ezinobunzima, kunye noxinzelelo olwaneleyo kuluhlu lwamaqondo obushushu ngokubanzi. Iqondo lobushushu eliqhubekayo liyi-105 ° C.

Ngokubanzi, umahluko wentsebenzo phakathi kwe-PA66 kunye ne-PA6 ngolu hlobo lulandelayo:

Iipropathi zoomatshini: PA66> Pa6

Ukusebenza okuphakathi: PA66> Pa6

Ixabiso: PA66> Pa6

Inqaku lokunyibilika: I-PA66> Pa6

Ukufunxa kwamanzi: I-PA66 <PA6

Ukuxhathisa kwemozulu: I-PA66 <PA6

Ixesha le-Quisonce: PA66 <PA6

Intsebenzo yokubumba: PA66 <PA6

4. Iimeko zeNkqubo

Unyango olomileyo

I-PA6 ifunxa ngokulula ukufuma, ingqwalaselo ekhethekileyo kufuneka ihlawulwe ukomisa ngaphambi kokuqhutywa. Ukuba izinto ezibonakalayo zinikezelwa kwizinto ezingaphantsi komhlaba, isitya kufuneka sigcinwe sivaliwe. Ukuba umswakama ungaphezulu kwe-0.2%, kuyacetyiswa ukuba yome ngomoya owomileyo owomileyo ngaphezulu kwe-80 ° C kwiyure ezi-3-4. Ukuba izinto ezibonakalayo ziveliswe kumoya ngaphezulu kweeyure ezi-8, kucetyiswa ukuba zome kwi-105 ° C ngaphezulu kwe-1 ukuya kwezi-2. Kungcono ukusebenzisa i-Dejumidi.

I-PA66 ukuba loo nto itywinwe ngaphambi kokuba isebenze, akukho mfuneko yome. Ukuba isitya sogcino sivuliwe, kuyacetyiswa ukuba some umoya oshushu, owomileyo nge-85 ° C. Ukuba umswakama ungaphezulu kwe-0.2%, kuyayimfuneko ukuqhuba ukonakala kwe-vacuum nge-105 ° C kwiyure enye ukuya kwezi-2. Kungcono ukusebenzisa i-Dejumidi. Iqondo lobushushu le-260 ~ 310 ° 80 ° 320 ~ 320 ° 2 ° C ukufumana iintlobo eziphuculweyo.

Iqondo lobushushu

I-PA6: 80 ~ 90 ° C. Ubushushu obubunjiweyo buchaphazela kakhulu i-crystallives, ethi ichaphazele iipropathi zoomatshini benxalenye.

Iinxalenye ezinqabileyo ezixineneyo, ezihamba ixesha elide, zikwacetyiswa ukufaka amaqondo obushushu aphezulu okumba. Ukonyusa ubushushu obubunjiweyo kukhulisa amandla kunye nokuqina kwenxalenye, kodwa kunciphisa ubunzima. Ukuba ubukhulu becala bungaphezulu kwe-3mm, kuyacetyiswa ukuba basebenzise ubushushu obungaphantsi kwe-20 ° 8 ° C. Kwiglasi yokuqiniswa kweqondo lobushushu lokudala kufuneka libe ngaphezulu kwe-80 ° C.

Pa66: I-80 ° C iyacetyiswa. Amaqondo obushushu abumba aza kuchaphazela i-crystallies, eya kuchaphazela iipropathi zomzimba zemveliso.

Kwiinxalenye zeplastiki ezinqatyisiweyo, ukuba iqondo lobushushu elinemililo elingaphantsi kwe-40 ° C lisetyenziswa, i-crystallity yenxalenye yeplastiki iya kutshintsha kunye nenqanaba le-PAMPIC, kwaye inyanga efundwayo iyafuneka.

Ubushushu bokunyibilika

I-Pa6: 230 ~ 280 ° 80 ° 250 ~ 280 ° C.

Pa66: 260 ~ 290 ° C. Imveliso yezicelo zeglasi yi-275 ~ 280 ° C. Ubushushu bokunyibilika kufuneka kuthintelwe ngaphezulu kwama-300 ° C.

Uxinzelelo lwenaliti

Zombini zihlala ziphakathi kwe-750 ne-1250 ibha (kuxhomekeke kwi-Nations kunye neMveliso).

Isantya senaliti

Zombini zisantya esiphezulu (esezantsi kancinci kwizixhobo ezizeziweyo).

Imbaleki neSango

Ukusukela ixesha le-PA6 kunye ne-PA66 lifutshane kakhulu, isikhundla sesango sibaluleke kakhulu. Isango lesango akufuneki libe ngaphantsi kwe-0.5 * t (phi i-t ubukhulu becala leplastiki). Ukuba imbaleki eshushu isetyenziselwa, ubungakanani besisango kufuneka bube mncinci kunelo mbaleki yesiqhelo kuba imbaleki eshushu inokunceda ukukhusela ukuqiniswa kwangaphambi kwexesha. Ukuba isango elinemikhono lisetyenziswa, ubuncinci besango sesango kufuneka ibe yi-0.75 mm.

5. Isicelo

I-PA6 yePlastiki zobunjineli inamandla aphezulu e-thensile, ukungavisisani kwempembelelo, ukunyangwa okungapheliyo, ukunganyangeki kwamachiza kunye nokuxabana okuphantsi. Banokuguqulwa yi-fiber ye-fiber, ukuguqulwa kwe-mineral kunye nelangatye. Iyenza ikhule kakhulu, ikakhulu isetyenziswa kwishishini lezithuthi kunye nezixhobo ze-elektroniki.

I-PA66 inesiphumo esihle sokusebenza, amandla aphezulu, ukungavisisani kwempembelelo, ukungavisisani kweoyile kunye nokunganyangeki, ngakumbi, ukunganyangeki kobushushu kunye nokusebenza kobushushu kunye nokusebenza kobushushu kunye nokusebenza kobushushu kunye nokusebenza kobushushu kunye nokusebenza kobushushu kunye nokusebenza kobushushu. I-PA66 isetyenziselwa ukuveliswa kwemisonto yemizi-mveliso efana neentambo ngenxa yamandla ayo aphezulu kune-PA6.

I-PA6 kunye ne-PA66 ngaphezulu kwezicelo ezininzi, kodwa apho i-PA6 inokusetyenziswa, i-PA66 ayisetyenziswanga.

Iplasitiki ye-AHD

Inkcazo yesitokhwe ngokubanzi ye-PA6:

Iphepha loku-1: 100 x 1000 x 2000mm (ubungakanani bobuqili bunokubonelelwa)

Imibala: mhlophe, mnyama, luhlaza, eminye imibala inoku-odolwa.
