PA612 wani abu ne na polymer, cikakken suna shine polyamide 612, wanda kuma aka sani da nailan 612. robobi ne na injiniya na semi-crystalline, tare da kyawawan kayan jiki da kwanciyar hankali na sinadarai.
Filastik ne na injiniyan Semi-crystalline tare da kyawawan kaddarorin jiki da kwanciyar hankali na sinadarai.A fagen aikin injiniya, ana amfani da PA612 sosai wajen kera sassa da sassa a cikin motoci, lantarki, injina da sauran fannoni.

Tsarin kwayoyin halitta na PA612 an kafa shi ta hanyar styrene monomer ta hanyar polymerisation mai radical.A lokacin aikin polymerisation, styrene monomer da farko ya fara samun ƙarin radical free radicals don samar da radicals na styrene, sannan waɗannan radicals suna ƙara samun ci gaban sarkar don samar da sarkar polymer.Wannan tsarin kwayoyin yana ba PA612 kyawawan kaddarorin inji da juriya.

Matsayin narkewa na PA612 shine zafin jiki wanda kayan ke canzawa daga m zuwa ruwa.Don PA612, wurin narkewa yana yawanci tsakanin 295-315 digiri Celsius.Matsayin narkewa a cikin wannan kewayon ya sa PA612 ya zama filastik injiniya tare da buƙatun zafin aiki mai girma.A cikin aikace-aikacen aikace-aikacen, kewayon ma'aunin narkewa na PA612 yana buƙatar ƙaddara bisa ga takamaiman yanayin aiki da kayan aiki.

Matsayin narkewa na PA612 yana shafar abubuwa daban-daban, ciki har da nauyin kwayoyin halitta na kayan, matakin crystallinity, girman hatsi da sauransu.Gabaɗaya magana, mafi girman nauyin kwayoyin halitta, mafi girma wurin narkewa;mafi girma da crystallinity, ƙananan wurin narkewa;ƙarami girman hatsi, mafi girma wurin narkewa.Sabili da haka, ana iya sarrafa kewayon ma'aunin narkewa na PA612 ta hanyar daidaita ma'aunin kwayoyin sa, crystallinity da girman hatsi da sauran sigogi.

A aikace-aikace masu amfani, kewayon wurin narkewa na PA612 muhimmin ma'auni ne.Da fari dai, yana ƙayyade buƙatun zafin aiki na PA612.Idan wurin narkewa ya yi ƙasa da ƙasa, zai iya haifar da narkewa ko rugujewar kayan yayin aiki;idan wurin narkewa ya yi tsayi da yawa, zai iya shafar aikin sarrafawa da rayuwar kayan aiki.Abu na biyu, kewayon yanayin narkewa kuma yana shafar dacewa da PA612 a cikin yanayin aikace-aikacen daban-daban.Alal misali, sassan da ake amfani da su a cikin yanayin zafi mai zafi suna buƙatar samun babban wurin narkewa don tabbatar da kwanciyar hankali da amincin su a yanayin zafi.

Baya ga kewayon wurin narkewa, PA612 yana da wasu mahimman kaddarorin jiki da sinadarai.Misali, ana siffanta shi da ƙarfi mai ƙarfi, ƙaƙƙarfan ƙarfi, ƙazanta mai kyau da juriya na lalata.Bugu da ƙari, PA612 yana da kyakkyawan tsari da kuma filastik, kuma ana iya sarrafa shi da kuma ƙera shi ta hanyoyi daban-daban, kamar ta hanyar yin allura da gyare-gyaren extrusion.

A ƙarshe, PA612 wani abu ne na polymer tare da kyakkyawan aiki, kuma ma'anar narkewar sa ya tashi daga 295-315 digiri Celsius.Gudanar da wannan kewayon yana da mahimmanci don tabbatar da aikin sarrafawa da tasirin aikace-aikacen PA612.Za'a iya samun ingantaccen iko na kewayon narkewa na PA612 ta hanyar zaɓi mai dacewa da daidaita sigogi kamar nauyin kwayoyin halitta, crystallinity da girman hatsi na PA612, don saduwa da buƙatun yanayin aikace-aikacen daban-daban.
