Kwishishini le-caster, izixhobo ze-nylon ziyathandwa ngenxa yokukrala kwazo okuhle kunye nokumelana nempembelelo kunye neempawu ezilungileyo zokucubungula. Phakathi kwazo, ii-caster ze-nylon PA6 kunye nee-caster ze-nylon MC njengeentlobo ezimbini eziqhelekileyo zee-caster ze-nylon. Nganye ineempawu zayo ezikhethekileyo kunye neemeko zokusetyenziswa. Eli nqaku liza kujonga umahluko phakathi kwezi ntlobo zimbini zee-caster, ukunceda abafundi bakhethe ngcono i-caster efanelekileyo kwiimfuno zabo.
I. Ukwakhiwa kunye nolwakhiwo lwezinto
Ii-casters ze-nylon PA6 zenziwe kakhulu nge-caprolactam monomer ngokusebenzisa i-polymerization. Zine-crystallinity ephezulu kunye namandla. Le nto, nangona igcina ubulukhuni kunye nokuqina okuphezulu, ikwanayo nokuqina okuthile kunye nokumelana nokukrala. Oku kwenza ukuba ibe lukhetho olusemgangathweni kwii-casters zokwenza.
Nangona ii-casters ze-nylon MC zisekelwe kwi-nylon PA6. Ukusebenza kwayo kuyaphuculwa ngokongezwa kwee-modifiers kunye nee-fillers. Ezi modifiers kunye nee-fillers zinokuphucula ukusilela kokusebenza kwe-nylon PA6. Umzekelo, ukuphucula ukumelana nokukrala, ukumelana nokugqwala kunye nokumelana nempembelelo. Ke ngoko. Ngelixa zigcina iimpawu ezisisiseko ze-nylon PA6, ii-casters ze-nylon MC nazo zisebenza ngcono ngokubanzi.
II. Iimpawu ezibonakalayo
Ii-casters ze-nylon PA6 zinamandla aphezulu kwaye zinobunzima. Ziqinile kwaye azinazo iintlungu. Oku kuyivumela ukuba iphumelele kwiindawo zokusebenza eziphantsi kwemithwalo ekhanyayo ukuya kwephakathi, amaqondo obushushu aphakathi (80-100 degrees) kwaye zifuna amanqanaba aphantsi engxolo. Nangona kunjalo, i-nylon PA6 inokumelana nobushushu okubuthathaka. kwaye inokuba neengxaki zozinzo kwiindawo ezithile ezithile.
Xa kuthelekiswa. Ii-casters ze-nylon MC, ngokusekelwe ekugcineni iipropati zomzimba ezisisiseko ze-nylon PA6. Ukumelana nokukrala okungcono, ukumelana nokugqwala kunye nokumelana nempembelelo kufunyanwa ngonyango lokuguqula. Oku kuyenza ifaneleke ngakumbi ukusetyenziswa kwiindawo ezinzima, ezinobushushu obuphezulu, nezinzima. Ukongeza, ii-casters ze-nylon MC zine-coefficient ephantsi yokungqubana. Ikwavelisa ingxolo encinci ngexesha lokusetyenziswa. Nika abasebenzisi indawo yokusebenza ezolileyo.
III. Iindlela zokucubungula kunye neendleko
Ii-casters ze-nylon PA6, ngenxa yezinga lazo eliphezulu le-crystallization ziyafuneka amaqondo obushushu aphezulu kunye noxinzelelo ngexesha lokucubungula. Oku kunokukhokelela kwiindleko eziphezulu zokucubungula. Nangona kunjalo, ikwaqinisekisa ukuba ii-casters zinamandla aphezulu kunye nobunzima.
Ii-casters ze-nylon MC ngenxa yonyango oluguquliweyo. Amaqondo azo obushushu kunye noxinzelelo oluphantsi. Kulula ukuzibumba nokuzilungisa. Oku kunika ii-casters ze-nylon MC inzuzo kwiindleko zemveliso. Nangona kunjalo. Ngenxa yesidingo sokongeza ii-modifiers kunye ne-fillers, ii-casters ze-Nylon MC zinokubiza ngaphezulu kancinci kunee-casters ze-nylon PA6.
IV. Iindawo zokusetyenziswa
Ii-casters ze-nylon PA6 ngenxa yeempawu zazo ezintle zomzimba kunye nexabiso eliphakathi. Zisetyenziswa kakhulu kwii-casters zefenitshala, ii-casters zeenqwelo, ii-casters zezixhobo zoshishino nakwezinye iindawo. Ziyakwazi ukuhlangabezana neemfuno zokusetyenziswa phantsi kweemeko zokusebenza eziqhelekileyo. Nika abasebenzisi inkxaso ezinzileyo nethembekileyo kunye neempawu zokuhamba.
Ii-casters ze-nylon MC zilungele ngakumbi ii-casters ezineemfuno eziphezulu zokusebenza. Ezifana nezixhobo zothutho ezisebenza nzima, ii-casters zokusetyenziswa kwiindawo ezinzima, njalo njalo. Ziyakwazi ukugcina ukusebenza okuzinzileyo phantsi kwemithwalo enzima, amaqondo obushushu aphezulu, iindawo ezinzima,... Nika abasebenzisi inkxaso ethembekileyo kunye nezisombululo zokuhamba.
Ukuqukumbela. Kukho umahluko phakathi kwee-casters ze-nylon PA6 kunye nee-casters ze-nylon MC ngokwezinto ezisetyenzisiweyo, iimpawu zomzimba, iteknoloji yokucubungula kunye nexabiso. Xa ukhetha ii-casters, abasebenzisi Kuya kufuneka ukhethe uhlobo olufanelekileyo lwe-caster ngokweemfuno zakho zokwenyani kunye nendawo yokusebenza. Ngeemfuno zokusetyenziswa phantsi kweemeko zokusebenza eziqhelekileyo. Ii-casters ze-nylon PA6 ziyindlela efikelelekayo; Kwaye kwii-casters ezineemfuno zokusebenza eziphezulu, ii-casters ze-Nylon MC ziyindlela efanelekileyo ngakumbi.
