Extruded polystyrene board (XPS) chinhu chinoshandiswa zvakanyanya pakuvaka insulation, uye zvivakwa zvayo zvinodzoreredza moto zvakakosha pakuchengetedza kuvaka. Iyo yekugadzira dhizaini yezvinodzosa moto yeXPS inoda kutariswa kwakadzama kwesimba remoto retardant, mashandiro ekugadzirisa, mutengo, uye zvakatipoteredza zvinodiwa. Pazasi pane yakadzama dhizaini uye tsananguro yemoto unodzoreredza maumbirwo eXPS, anofukidza ese halogenated uye halogen-isina murazvo retardant mhinduro.
1. Dhizaini Mitemo yeXPS Flame Retardant Formulations
Chinhu chikuru cheXPS ndeye polystyrene (PS), uye gadziriso yayo inodzoreredza murazvo inowanikwa nekuwedzera zvinodzosa moto. Iyo dhizaini yekugadzira inofanirwa kutevedzera zvinotevera misimboti:
- High flame retadancy: Sangana nemirazvo inodzoreredza mirazvo yezvinhu zvekuvaka (semuenzaniso, GB 8624-2012).
- Processing performance: Iyo inodzoreredza murazvo haifanire kukanganisa zvakanyanya kupupa uye kuumba maitiro eXPS.

- Dzora tembiricha yeextrusion pa180-220 ° C kuti uve nechokwadi chekupupa uye kuumbwa.
(3) Hunhu:
- Zvakanakira: High flame retardant performance, yakaderera yekuwedzera mari, uye yakaderera mutengo.
- Zvakaipa: Inogona kuburitsa magasi ane muchetura (semuenzaniso, hydrogen bromide) panguva yekupisa, zvichiunza kunetseka kwezvakatipoteredza.
3. Halogen-Free Flame Retardant XPS Formulation
Halogen-isina murazvo retardants (semuenzaniso, phosphorus-based, nitrogen-based, kana inorganic hydroxides) inowana kudzoreredza murazvo kuburikidza nekunyudza kupisa kana kugadzira matanda ekudzivirira, ichipa zvirinani kuita kwezvakatipoteredza.
(1) Kuumbwa Kwekugadzirisa:
- Polystyrene (PS): 100phr (base resin)
- Phosphorus-based flame retardant: 10–15phr (semuenzaniso,ammonium polyphosphate (APP)kana tsvuku phosphorus)
- Nitrogen-based flame retardant: 5–10phr (semuenzaniso, melamine cyanrate (MCA))
- Inorganic hydroxide: 20-30phr (semuenzaniso, magnesium hydroxide kana aluminium hydroxide)
- Foaming agent: 5-10phr (semuenzaniso, carbon dioxide kana butane)
- Dispersant: 1-2phr (semuenzaniso, polyethylene wakisi, inovandudza kupararira)
- Lubricant: 1-2phr (semuenzaniso, zinc stearate, inowedzera kugadzirisa fluidity)
- Antioxidant: 0.5-1 chikamu (semuenzaniso, 1010 kana 168, inodzivirira kuora panguva yekugadzirisa)
(2) Maitiro ekugadzirisa:
- Premix PS resin, flame retardant, dispersant, lubricant, uye antioxidant zvakafanana.
- Wedzera iyo inoputika mumiriri uye nyungudusa-musanganiswa mune extruder.
- Dzora tembiricha yeextrusion pa180-210 ° C kuti uve nechokwadi chekupupa uye kuumbwa.
(3) Hunhu:
- Zvakanakira: Hushamwari kwezvakatipoteredza, hapana magasi ane muchetura anogadzirwa panguva yekupisa, zvinoenderana nemirairo yezvakatipoteredza.
- Zvakaipa: Kudzika kwemoto kudzoreredza kushanda zvakanaka, huwandu hwekuwedzera hwekuwedzera, hunogona kukanganisa makina ezvivakwa uye kuita kwefuro.
4. Mafungiro Akakosha Mukugadzira Dhizaini
(1) Flame Retardant Selection
- Halogenated flame retardants: Kunyanya kushanda zvakanaka asi kunoisa njodzi kwezvakatipoteredza uye hutano.
- Halogen-isina murazvo retardants: Yakawedzera hushamwari kwezvakatipoteredza asi inoda huwandu hwekuwedzera hwekuwedzera.
(2) Kushandiswa kweSynergists
- Antimony trioxide: Inoshanda synergistically nehalogenated flame retardants kuti iwedzere zvakanyanya kunonoka kwemurazvo.
- Phosphorus-nitrogen synergy: Mune halogen-isina masisitimu, phosphorus uye nitrogen-based flame retardants inogona kushanda pamwechete kuti ivandudze kushanda zvakanaka.
(3) Kupararira uye Processability
- Dispersants: Iva nechokwadi chekupararira kweyunifomu yezvinodzosa moto kudzivirira nzvimbo dzakakwirira.
- Mafuta ekuzora: Kuvandudza kugadzirisa fluidity uye kuderedza kupfeka kwemidziyo.
(4) Foaming Agent Selection
- Muviri unopupa zvinhu: Zvakadai seCO₂ kana butane, zvakatipoteredza zvine hushamwari nemhedzisiro inopupa.
- Kemikari inopupa furo: Zvakadai se azodicarbonamide (AC), yakakwira furo kushanda zvakanaka asi inogona kuburitsa magasi anokuvadza.
(5) Antioxidants
Dzivirira kuparara kwezvinhu panguva yekugadzirisa uye kuwedzera kugadzikana kwechigadzirwa.
5. Typical Applications

7. Zvakatipoteredza uye Regulatory Zvinodiwa
- Halogenated flame retardants: Inodziviswa nemirairo seRoHS uye REACH; shandisa nekungwarira.
- Halogen-isina murazvo retardants: Tevedzera mirau yezvakatipoteredza uye unomiririra mafambiro emangwana.
Summary
Iyo yekugadzira dhizaini yezvinodzosa moto yeXPS inofanirwa kunge yakavakirwa pane chaiwo mamiriro ekushandisa uye zvinodikanwa zvekutonga, kusarudza pakati pehalogenated kana halogen-isina moto retardants. Halogenated flame retardants inopa kushanda kwepamusoro asi inokonzeresa zvinonetsa kwezvakatipoteredza, nepo halogen-isina murazvo retardants ine hushamwari nharaunda asi inoda huwandu hwekuwedzera. Nekugadzirisa magadzirirwo nemagadzirirwo, kuita kwepamusoro-soro, eco-hushamwari, uye inodhura-inoshanda murazvo-inodzoreredza XPS inogona kugadzirwa kuti isangane nezvinodiwa zvekuvharisa kwekuvaka uye mamwe minda.
