Nzira yekubatanidza isina halogen yekubatanidza mabhatani emagetsi e-acrylic akagadzirwa nemvura
Muma acrylic systems akavakirwa mumvura, huwandu hwekuwedzera hwealuminium hypophosphite (AHP) ne zinc borate (ZB) hunofanirwa kutariswa zvichienderana nezvinodiwa zvekushandiswa (zvakadai sekudzora moto, ukobvu hwekufukidza, zvinodiwa pakushanda kwemuviri, nezvimwewo) uye mhedzisiro yazvo yekubatana. Heano mazano akajairika uye huwandu hwereferensi:
I. Nhamba Yekuwedzera Yemari Yekutanga
Tafura: Zvimwe Zvinokurudzirwa Zvinodzivirira Moto uye Tsananguro
| Rudzi Runodzivirira Murazvo | Kuwedzera Kunokurudzirwa (wt%) | Tsananguro |
| Aluminium Hypophosphite (AHP) | 5%~20% | Chinodzivirira moto chakagadzirwa nephosphorus; enzanisa kushanda kwemumoto nekuenderana kwehurongwa (huwandu hwakawanda hunogona kukanganisa hunhu hwemuchina). |
| Zinc Borate (ZB) | 2%~10% | Synergistic enhancer; inogona kuderedza kuwedzera kwese kana ikasanganiswa neAHP (huwandu hwakawanda hunodiwa kana ikashandiswa yoga). |
II. Kugadziriswa kweCompound Ratios
- Zviyero Zvakajairika zveCompound:
- AHP:ZB = 2:1 ~ 4:1(semuenzaniso, 15% AHP + 5% ZB, huwandu hwese hwe20%).
- Gadzirisa zviyero uchishandisa bvunzo, semuenzaniso:
- Kudiwa kwekudzora murazvo kwakanyanya:AHP 15%~20%, ZB 5%~8%.
- Hunhu hwemuviri hwakaringana:AHP 10%~15%, ZB 3%~5%.
- Mhedzisiro yekubatana:
- Zinc borate inowedzera kunonoka kwemurazvo ne:
- Kusimbisa kuumbwa kwechar (kubatana nearuminiyamu phosphate inogadzirwa neAHP).
- Kusunungura mvura yakasungwa kuti itore kupisa uye kuderedza magasi anobvira.
III. Matanho Ekusimbisa Ekuyedza
- Kuedzwa kwematanho:
- Kuedzwa kwemunhu mumwe nemumwe:Kutanga ongorora AHP (5%~20%) kana ZB (5%~15%) zvakasiyana kuti uone kana moto usingaperi (UL-94, LOI) uye kushanda kwepachifukidziro (kunamatira, kuomarara, kuramba mvura).
- Kugadzirisa zvinhu zvakasiyana-siyana:Mushure mekusarudza huwandu hwekutanga hweAHP, wedzera ZB zvishoma nezvishoma (semuenzaniso, 3% kusvika 8% kana AHP iri 15%) uye ona kuvandudzwa kwekunonoka kwemoto uye migumisiro yadzo.
- Zviratidzo Zvikuru zveKushanda:
- Kunonoka kwemurazvo:LOI (chinangwa ≥28%), chiyero cheUL-94 (V-0/V-1), kuwanda kweutsi.
- Zvimiro zvemuviri:Kuumbwa kwefirimu, kunamira (ASTM D3359), kuramba mvura (hakuna kucheka mushure mekunyudzwa kwemaawa makumi mana nemasere).
IV. Zvinhu Zvikuru Zvekufunga nezvazvo
- Kugadzikana Kwekupararira:
- AHP inogadzirwa ne hygroscopic - inoomeswa isati yaoma kana kushandisa mhando dzakagadziriswa pamusoro.
- Shandisa zvinoparadzira mvura (semuenzaniso, BYK-190, TEGO Dispers 750W) kuti uvandudze kufanana uye kudzivirira kudonha kwemvura.
- Kuenderana kwe pH:
- Masisitimu e acrylic akavakirwa mumvura anowanzova ne pH ye8–9; ita shuwa kuti AHP ne ZB zvinoramba zvakagadzikana (kudzivirira hydrolysis kana kuora).
- Kutevedzera Mutemo:
- AHP inofanira kusangana nezvinodiwa zveRoHS zvisina halogen; ZB inofanira kushandisa magiredhi asina kuchena esimbi ine heavy-metal.
V. Mhinduro Dzakasiyana kana Dzekuwedzera
- Melamine Polyphosphate (MPP):Inogona kuwedzera kunonoka kwemurazvo kana ikasanganiswa neAHP (semuenzaniso, 10% AHP + 5% MPP + 3% ZB).
- Zvidziviriro zveNano Flame:Nano-grade ZB (kuwedzera kwakaderedzwa kusvika 1%~3%) kana layered double hydroxides (LDH) kuti pave nekuvandudzwa kwemhedzisiro yekudzivirira.
VI. Pfupiso yeZvinokurudzirwa
- Kutanga kuumbwa:AHP 10%~15% + ZB 3%~5% (huwandu hwe13%~20%), wobva wagadzirisa.
- Nzira yekusimbisa:Edzai mienzaniso midiki yeLOI neUL-94 muchiongorora hunhu hwemakanika.
