Nylon (Polyamide, PA) waa balaastiig injineernimo oo heersare ah oo si ballaaran loogu isticmaalo elektiroonigga, baabuurta, dunta, iyo qaybaha kale. Dabacsanaantiisa awgeed, wax ka beddelka dab-dejinta naylon ayaa si gaar ah muhiim u ah. Hoos waxaa ah naqshad faahfaahsan iyo sharraxaad qaabeynta dib-u-dejinta ololka naylon, oo daboolaya labadaba xalalka dib-u-dhigista ololka halogenated iyo halogen-la'aanta.
1. Mabaadi'da Naqshadeynta Dabcinta Ololka Nylon
Naqshadeynta qaababka dib u dhigista ololka naylon waa in ay raacdaa mabaadi'da soo socota:
- Dib u Dhigista Ololka SareLa kulan heerarka UL 94 V-0 ama V-2
- Habaynta WaxqabadkaDib-u-dhacyada ololku waa in aanay si weyn u saamaynayn waxyaabaha nayloonka ah ee farsameeya (tusaale, dareeraha, xasilloonida kulaylka).
- Guryaha Makaanikada: Ku-darka dab-demiska ololku waa inuu yareeyo saamaynta xoogga nayloonka, adkaanta, iyo xidhashada caabbinta.
- Saaxiibtinimada deegaankaMudnaanta sii dabciyaasha ololka aan halogen lahayn si ay ugu hoggaansamaan xeerarka deegaanka.
2. Samaynta Nayloonka Ololka Halogenated
Dib-u-celiyayaasha ololka halogenaysan (tusaale, iskudhisyada brominated) waxay kala gooyaan falcelinta silsiladda gubashada iyagoo sii daaya xag-jirrada halogen, iyagoo bixinaya waxtarka dib u dhigista ololka sare.
Habaynta:
- Xabagta naylon (PA6 ama PA66): 100 phr
- Dib-u-dhigista ololka burburay: 10-20 phr (tusaale, decabromodiphenyl ethane, boom polystyrene)
- Antimony trioxide ( synergist): 3-5 phr

- Antioxidant: 0.5-1 phr (tusaale, 1010 ama 168)
Tallaabooyinka Habaynta:
- Premix resin naylon, olol retardant, synergist, saliid, iyo antioxidant si siman.
- Ku dhalaali-isku darka adoo isticmaalaya faashad mataano ah oo pelletize.
- Xakamee heerkulka ka saarida 240-280 ° C (ku hagaaji nooca naylon).
Astaamaha:
- Faa'iidooyinka: Hufnaanta dab-demiska sare, qadar yar oo lagu daro, kharash-ool ah.
- Khasaaro: Sii daynta suurtagalka ah ee gaaska sunta ah inta lagu jiro gubashada, welwelka deegaanka.
3. Samaynta Nayloonka Dabka Dabacsan ee Halogen-free
Halogen-free olol retardants (tusaale, fosfooraska ku salaysan, nitrogen-ku salaysan, ama hydroxides inorganic) waxay ku shaqeeyaan falcelinta endothermic ama samaynta lakabka ilaalinta, oo bixiya waxqabad deegaan oo wanaagsan.
Habaynta:
- Xabagta naylon (PA6 ama PA66): 100 phr
- Fosfooraska ku salaysan ololka: 10-15 phr (tusaale, ammonium polyphosphate APP ama fosfooraska cas)
- Dib u dhiga holac ku salaysan Nitrojiin: 5-10 phr (tusaale, melamine cyanurate MCA)
- Hydroxide aan organic: 20-30 phr (tusaale, magnesium hydroxide ama aluminium hydroxide)
- Saliid: 1-2 phr (tusaale, zinc stearate)
- Antioxidant: 0.5-1 phr (tusaale, 1010 ama 168)
Tallaabooyinka Habaynta:
- Premix resin naylon, olol retardant, lubricant, iyo antioxidant isku mid ah.
- Ku dhalaali-isku darka adoo isticmaalaya faashad mataano ah oo pelletize.
- Xakamee heerkulka ka saarida 240-280 ° C (ku hagaaji nooca naylon).
Astaamaha:
- Faa'iidooyinka: Deegaanka saaxiibtinimo leh, aan lahayn qiiqa gaasta sunta ah, u hoggaansan xeerarka.
- KhasaaroWaxtarka hoos u dhaca holac, xaddi badan oo lagu daro, saamaynta suurtagalka ah ee sifooyinka farsamada.
4. Tixgelinta Muhiimka ah ee Nakhshadeynta
(1) Xulashada Ololka Retardant
- Dib-u-celinta ololka halogenatedWaxtarka sare laakiin waxay keenaysaa khataraha deegaanka iyo caafimaadka.
- Dab-celiyayaasha ololka aan halogen lahayn: Eco-saaxiibtinimo laakiin waxay u baahan tahay xaddi badan waxaana laga yaabaa inay saamayso waxqabadka alaabta.
(2) Isticmaalka isku-dhafka
- Antimony trioxide: Wuxuu si isku mid ah ula shaqeeyaa dab-celiyayaasha ololka halogenaysan si kor loogu qaado dib u dhaca ololka.
- Fosfooraska-nitrogen isku-dhafka: Nidaamyada aan halogen-la'aanta ahayn, fosfooraska iyo nitrogen-ku-salaysan ololka dab-demiska ayaa is-waafajin kara si loo hagaajiyo waxtarka.
(3) Kala-firdhinta iyo Hab-socodka
- Kala firdhiyey: Hubi kala firdhisanaanta isku midka ah ee dab-celiyayaasha ololka si aad uga fogaato uruurinta sare ee gudaha.
- Saliidaha: Hagaajinta dareeraha farsamaynta oo yaree xirashada qalabka.
(4) Antioxidants
Kahortagga wax-u-dhimista walxaha inta lagu jiro farsamaynta iyo xoojinta xasilloonida alaabta.
5. Codsiyada caadiga ah
- Elektrooniga: Qaybaha ololka celinaya sida xirayaasha, furayaasha, iyo saldhigyada.
- Baabuur: phr ololka-celisa sida daboolka mishiinka, xadhkaha fiilooyinka, iyo qaybaha gudaha.
- Dharka: Fiber iyo maryo ololka celisa.
6. Talooyinka Hagaajinta Habaynta
(1) Kobcinta Waxtarka Dib u Dhigista Ololka
- Isku darka ololka retardant: Halogen-antimony ama fosfooraska-nitrojiinka isku-dhafka si kor loogu qaado waxqabadka.
- Nano ololka dib u dhigaTusaale ahaan, nano magnesium hydroxide ama dhoobo nano, si kor loogu qaado waxtarka loona yareeyo qadarka wax lagu daro.
(2) Hagaajinta Guryaha Makaanikada
- AdkeeyayaashaTusaale ahaan, POE ama EPDM, si kor loogu qaado adkaanta walxaha iyo iska caabinta saamaynta.
- Xoojinta buuxinayaasha: Tusaale ahaan, fiber galaas, si loo hagaajiyo xoogga iyo qallafsanaanta.
(3) Dhimista Qiimaha
- Hagaajin saamiga dib u dhigista ololkaYaree isticmaalka intaad buuxinayso shuruudaha daahitaanka ololka.
- Dooro walxo kharash-ku-ool ahTusaale ahaan, dab-demiska dabka ee gudaha ama isku-dhafka ah.
7. Shuruudaha Deegaanka iyo Xeerarka
- Dib-u-celinta ololka halogenatedWaxaa xaddiday RoHS, REACH, iwm, oo u baahan isticmaalka taxaddar leh.
- Dab-celiyayaasha ololka aan halogen lahayn: U hoggaansan xeerarka, oo matalaya isbeddellada mustaqbalka.
Naqshadeynta qaababka dib u dhigista ololka naylon waa in ay tixgeliyaan xaalado gaar ah oo codsi ah iyo shuruudaha sharciyeed marka la dooranayo dib-u-celinta ololka halogenaysan ama halogen-la'aanta. Dib-u-celinta ololka halogenated waxay bixiyaan waxtar sare laakiin waxay keenaan khataro deegaanka ah, halka beddelka halogen-la'aanta ah ay yihiin kuwo saaxiibtinimo leh laakiin waxay u baahan yihiin xaddi badan oo lagu daro. Marka la wanaajiyo habaynta iyo hababka, wax ku ool ah, deegaanka saaxiibtinimo, iyo agab naylon olol-celisa oo kharash-ool ah ayaa la soo saari karaa si loo daboolo baahiyaha qalabka elektiroonigga ah, baabuurta, dunta, iyo warshadaha kale.
